Hey, y'all! It's been a while since I've written a story on this site. I miss writing, so, here is the thing: Gimme a picture of a nice, buff guy, or a morphed up guy, or something, and I'll write a story for the picture! It'll be a short story, but I'll do it! Cause I feel like it would be fun! So, don't hesitate to share!

Here's the third instalment of my growing dad story. This will be the final part of the growth act. If i continue writing more in the future, it will be about living with their newfound size rather than growing them bigger. I hope you guys enjoy, let me know what you think in the comments. Part One and Two Like Father, Like Son Part Three "Do you know where I can get more of that stuff?" Darren grinned to himself and flexed his pecs, working on tensing the muscles one at a time. Beside him Darren's father Lawrence struggled to control the steering wheel around his own chest. His Dad's biceps fought for space against his pecs, and his huge hands had already gripped and distorted the plastic wheel. The two men had struggled to fit inside his fathers beat up pickup, but it had been an enjoyable struggle, and Darren felt his cock throb in his tight sweatpants as his fathers massive muscular arm tensed and rubbed against his own. Both men had one arm hanging out a window to make more room within the cab, but they were so wide they couldn't avoid pressing against one another. Not that they would want to. When his father had asked for more of the chemicals that had turned them into muscle gods, his cock had shot back to full hardness, throbbing between his massive pecs. This had in turn gotten his father hard again, and the two of them has been 'forced' to rub their enormous cocks against each other, flexing their new manly pecs together until both had blasted another load across their kitchen ceiling. Darren and his father's libidos were so active they had struggled to control themselves long enough to go upstairs and find some sort of clothing that fit. The results of that search had been laughable. Darren had stuffed his thick quads and enormous cock into a pair of formerly baggy sweatpants. A once loose tank top was now stretched across his broad chest and rode up enough to expose the lower third of his rock hard stomach. His father hadn't managed much better, an old pair of basketball shorts now clinging to his thighs and ass, barely long enough to cover the length of his extraordinary cock and definitely not enough to support or obscure his huge cantaloupe sized nuts. Lawrence had tried pulling on several shirts, and both father and son had been turned on watching Lawrence's enormous upper body shred through and tear each garment like tissue paper. In the end his father had opted to go shirtless. This was fine with Darren as it meant he had an unobscured view of his father's hugely swollen chest muscles while they bounced and quivered with his Dad's every motion. The two hairy masses made driving difficult, but his fathers grin suggested to Darren that Lawrence didn't mind. The way his father had flexed his massive bicep at another car when stopped at a red light, leering and laughing at the shocked men next to them, told Darren his Dad was fully in love with his new body. It was late by the time they left the house, and as they approached the University campus the sun had set. Darren was glad as it meant they would attract less attention when they made their way into the science building. He wasn't sure how to explain the presence of two eight foot tall muscle gods on campus, and would rather wait until they were even Bigger before trying. "Take the next left Dad, and then we can park right there," said Darren, pointing to an empty parking lot next to the chemistry building. Or trying to point, his own bulk and his father's meaning he mostly flexed his bicep against his Dad's tricep while barely lifting his forearm. His Dad smirked and reached down to rub Darren's thigh, making his cock jump and throb in his sweats in response. His Dad laughed and gave Darren's cock a quick squeeze as well as he brought the pickup to a halt. Exiting the vehicle proved just as difficult as entering, and Darren bent the door nearly off it's hinges in the attempt. He was shocked when the door refused to close and he saw the imprints of his fingers on the door panel. Darren was distracted by cursing from the drivers side, arriving just in time to see the door fly fully off it's hinges and land with a crash on the asphalt. One massive quad and thick calf emerged, huge bare foot thudding solidly on the pavement. Neither massive man had fit into shoes, and Darren found himself strangely turned on. They were both so Big! Another string of curses mixed with deep laughter drew Darren's attention, and he stepped in to help his father. Grabbing one arm, he helped pull his Dad free of the truck, hearing the steering column crunch and twist. The truck sprung upward as his Dad exited, and Darren had to wonder just how much the two of them weighed now. As his father stood up and stretched his neck and arms, he spoke. "Damn son, they really don't build them like the used to huh?" He patted the truck roof with one meaty hand, then frowned as he noticed the bits of metal and plastic caught in his chest hair. Darren helped Lawrence brush them from his furry pelt, then spent a few moments caressing and exploring his Dad's huge fuzzy chest with his hands. Lawrence then pulled Darren in for a swift kiss, chests pressed tightly together. Darren felt his Dad's cock and ball throb in response to his own, before his Dad pushed him away. "Enough of that for now kid, save it for when we're Growing again," his Dad growled, eyes gleaming with desire. Darren mock saluted his father, bicep and forearm making it difficult. "Yes sir, lead the way," he joked. "Darren, this is your school. I don't know where we're going. I can barely see over my pecs anyway." Lawrence puffed up his hairy chest proudly as he spoke. Darren had to admit it was more difficult to adjust to his new size than he expected. As both he and his Dad strutted towards the science building, he felt his thighs rubbing together, had to adjust his stride and swing his legs wide around one another. His large nuts and impossibly huge cock also swayed and bounced distractingly in his sweatpants, and he enjoyed every jolt of his heavy testicles in his sack. His father next to him was the biggest distraction of all, a walking mountain of muscle that flexed and bounced with his every stride. He was so distracted by his fathers mass that he walked right into the doors, thumping against them and cracking the glass with his chest. Darren blushed and tried to fish in his small pockets with his giant hand for his keycard, while his father roared with laughter and congratulated him for growing up into a real man. Darren scanned his card and the two of them ducked and lumbered awkwardly through the entry. Looking at the small card in his palm, Darren shrugged and tucked it between his pecs for easier access compared to his skintight pockets. The chemistry building was empty at this hour. Students were allowed to work late, but on a Friday night there was no one to be seen. The automatic lights lit up ahead of them, and dimmed again behind them. The thumping of their bare feet and the subtle creaking and groaning of their muscles provided an organic counterpoint to the low electric hum and mechanical background noises of the building. "We need to get to the third floor," Darren said in a low voice. He felt himself more on edge now, anxious at the thought of being discovered sneaking in. "Is there an elevator nearby then?" His Dad also spoke in a subdued voice. Looking over, Darren almost laughed. They were both slightly hunched, instinctively trying to make themselves smaller to attract less attention. A completely ridiculous and pointless endeavour for the two muscular titans. Darren forced himself to stand up straighter and relax his shoulders. He watched his father do the same. "I don't think we're going to fit in the elevator Dad. Plus I don't think it's rated for our weight!" Darren winked and bounced his chest suggestively. "Alright Mr. Massive, let's take the stairs. Lead the way." Darren set out, down one corridor and up a second. The main stairs on the first floor were broad and decorative, giving the two men plenty of room to make their way up. Darren's new stride meant he took the steps three at a time comfortably. A broad hand on his ass told him his father appreciated the view, and Darren made sure to flex his powerful globes with every step. The hand on his ass squeezed in appreciation, and Darren swallowed a deep chuckle. The second floor hallways were narrower and darker, banks of lockers lining the walls. Darren lead the way again, his father a warm presence looming behind him. The floors farther up were restricted, and Darren had to swipe his tiny keycard to let them access the much smaller concrete stairwell. The metal steps clanged dully under their feet, the enclosed stairwell booming with the echoes of their passage. Darren felt the hair on his neck rise, certain somebody would notice the noise and that they'd be discovered. He scanned his keycard again at the third floor and both massive men ducked through the door, relieved to be in a quieter hallway again. They stood in an island of light, massive muscles gleaming from anxious sweat. Darren felt his Dad's hand on his shoulder and his Dad's lips near his ear. "Alright son, where to from here?" Lawrence whispered. Darren had to clear his throat and swallow before whispering his reply. "Two hallways over and three more down. We're looking for room 313." Both men set out, trying to walk quietly. Darren found he required a surprising amount of effort to control the strike of his heel. His mass was so immense now, it just felt natural to be loud. The rubbing of his muscles was also a constant distraction, his cock in his sweats demanding more attention due to his increased libido. It was natural in his distracted state, with the sexy mass of his father behind him, that he almost missed the warning glow of lights approaching the hallway intersection ahead of them. A hissed breath behind him and a hand grasping his shoulder alerted him. Darren stopped, frozen, unsure what to do as lights switched on ahead and quiet footsteps came towards him. His Dad pulled him back, finger to his lips, and jerked his head towards the intersection behind them. The two men hustled as best they could, as quietly as they could, towards that perceived shelter. His Dad turned the corner just ahead of him, broad back barely out of sight when a voice behind Darren froze him in his tracks. "Hey! You! Are you supposed to be here?" Darren looked at his father in stunned panic. Lawrence looked uncertainly back. Then Darren watched a grin spread across his Dad's face. The older man straightened up and relaxed his shoulders. He gave Darren a reassuring look and a wink, puffing out his chest and gesturing Darren to turn back. He also tapped his chest, once, twice, three times, until Darren realized his father was indicating the keycard tucked between Darren's own pecs. Darren felt relief surge through his body, and his dad nodded encouragement. Then Lawrence turned and began to tiptoe his way down the corridor. The sight of his giant muscular Dad trying to be sneaky was so ridiculous Darren couldn't help letting out a quiet giggle. He stifled that a moment later as he heard footsteps stomping towards him from the other hall. "Hey, Buddy." The voice was insistent, but not yet rude. "This floor is restricted, I'm going to need to see your... ID... please..." The voice trailed off as Darren turned, standing up to his full eight foot height. He crossed thick rippling arms across his broad chest and smiled down at the security guard staring up at him in slack jawed awe. "Good evening little guy. What was that you were saying?" Darren forced himself to sound more confident than he was feeling. The butterflies in his stomach told him his confidence hadn't yet grown as big as his body. The security guard shook his head, obviously trying to collect himself, and just as obviously distracted by Darren's massive muscles. Darren decided to help the man out, and began to flex his pecs, slowly, one at a time, making the massive mounds swell up and tighten before relaxing and bouncing back down under his 'shirt'. "I, I uh, I need to see your ID. Please. These floors are uh, restricted to chemistry students only. Dangerous." The smaller man stood there, clearly not sure what else to say to the giant in front of him. Darren felt a second wave of relief, and relaxed his posture even more. He reached between his pecs and pulled out his keycard. "Sure thing big guy, no worries. You having a busy night?" Darren passed down the card, slick with his sweat, smirking as he noticed the security guards hand trembling as he took it. He looked for a moment at the card, then up in disbelief at Darren. Darren helpfully leaned forward, looming over the smaller man. "Sorry bud, I know it's hard to see my face sometimes over my chest." Darren flexed his chest muscles to prove the point. He looked down and winked at the security guard. The man was clearly in his late twenties, not much older than the students he policed, and he was obviously being turned on by Darren's body. "Y-you weren't kidding," stammered the security guard. "How come I haven't noticed YOU before. A guy your size should be famous! Are you really supposed to be here?" Darren let out a deep laugh, lifting one arm up to flex his bicep. He was beginning to enjoy the lusty look on the smaller mans face. "Yup, I'm just here to get a little chemistry homework done. It's easier to do without a bunch of people around, you know?" Darren wiggled his wrist, making the bicep dance. "What's your name by the way?" "Stan. Uh Stanley, and you're-" the security guard checked the card again. "Darren." "Yep that's me." Stan still seemed unsure and floundering. "You uh, you don't look as big in your picture." Darren bent down, getting closer to the smaller mans face, his huge chest in danger of knocking the guard back. "Yeah, they just zoomed in really close on my face. I think the photographer didn't like my chest being in the way." Stan reached out tentatively, almost touching Darren's chest, before catching himself and coughing. Blushing, the smaller man transferred Darren's keycard to that hand and held it back out to Darren. Darren grinned and gently grasped the security guards wrist. He helped guide Stan's hand to tuck the keycard back between his thick pectorals. The security guard blushed and gasped, and Darren fought to keep from grinning as he noticed the wet spot on Stan's pants. He stood back up and leaned against a locker, denting it with his elbow, and looked back down at Stan. "So do you work here very often? Will I be seeing you again?" Darren felt almost ashamed at how much he was affecting the poor little man. But he felt a tingling excitement instead. He lifted both arms up and gave the shorter man a huge double bicep flex, and flexed his cock in his sweatpants as well. Beads of sweat broke out on Stan's forehead, the wet spot in his pants growing darker. The security guard half hunched and gasped. "Y-yeah probably. But I, I should get back to m-my rounds. Don't w-want to keep you, from homework." Darren could see Stan's dick throbbing in his pants and took pity on the smaller man. "Well alright then Stan, it was nice meeting you. Maybe I'll see you in the gym sometime." Darren rested his hands on Stan's shoulders, gently moving him aside so Darren could slowly slide past the man, letting his prominent bulge 'accidentally' graze against Stan. Darren began to walk away and turned to wink back over his shoulder, seeing Stan bite his lip. He then heard footsteps rushing away in the direction of the nearest bathroom. Darren held his breath until he heard a door slam and then threw his head back to let out a deep laugh. The tension bled from his body, leaving him trembling slightly. It was going to take time adjusting to his new body, but he thought he was going to thoroughly enjoy doing so. Darren rushed down the hall, taking the remaining turns until at last he reached room 313. He ducked inside and closed the door behind him, turning to see his father at the far end of the classroom silhouetted by the light from the fridge. His father held a clear vial between his fingers as he turned to Darren and grinned. "Bottoms up son!" said Lawrence as he drained half the vial in a single swig. Darren stood frozen, watching his father, waiting for the growth he knew was about to occur. His father beamed, holding the vial loosely in one hand, looking down at himself and gently flexing his other forearm. Both of them waited in silence for nearly a minute before the disappointment set in. "Nothing is happening." "Dad did you feel anything?" Both men spoke at once. Darren's father looked chagrined as Darren made his way across the room. "What is it Darren? Did I grab the wrong stuff?" Darren bent down to peer into the cooler, seeing two more vials of clear liquid within the refrigerator. "No Dad, this is the right room, and those are the vials that were left over when I went home today. It should have worked. Can I see that?" Darren took the glass from his father and peered at the small label. "Do you remember which vial did what back at the house?" "How should I know son, you didn't label them remember? I think the pink one grew my muscles?" "Pink..." Darren said under his breath, looking at the vial. It took him another moment to realize the vial he held and the vials in the cooler were each clear liquid. "That's what's different Dad. The stuff we drank all had different colours. These are all still clear. But I don't know why." "Were they clear when you brought them home earlier? Did somebody change what was in here after you left?" Darren could hear the impatience and frustration in his fathers voice as Lawrence was denied the size he craved. "These are the same solutions I brought home with me earlier. They have to be kept cool, that's why I put them in our fridge." Darren frowned, then snapped his fingers as inspiration dawned. "Dad, they were supposed to stay cool! But they didn't, everything heated up when I was in the car driving home. That's why they're still clear, they're still cold!" Darren watched his Dad's face, saw disappointment give way to thoughtfulness, and then a full grin. Darren stepped aside as his father reached past him, grabbing the remaining two vials and the one still held in Darren's hand. "Alright son, we better find a way to make these hotter." Lawrence smirked as he carefully places first one, then the second tube from the fridge between his mammoth pecs. The huge hairy muscles easily held the vials in the crevasse between them, and Lawrence reached out to tuck the third one safely into Darren's own meaty chest. Then he stepped closer and wrapped his arms around Darren's back, pulling him close. Darren immediately felt himself heating up from his father's proximity, and couldn't help letting out a low moan as his Dad pressed the stretched crotch of his basketball shorts against Darrens equally bloated junk in his sweat pants. "Looks like things are heating up already," said Lawrence, smiling and leaning in to kiss Darren. Darren kissed back, hungry for his fathers lips, grinding his cock against his fathers massive thighs. Darrens own arms wrapped around his fathers broad back, hands grasping and groping his father's heavy slabs of muscle. He broke the kiss and traced his tongue along the heavy muscles of his father's neck, tasting the salty sweat already glistening across Lawrence's body as the two titans groped and pressed against each other. His father's hands pulled his face downwards, pressing Darrens face against his father's bloated chest. Darren obliged him and licked the huge hairy globes of beef, groaning as his father moaned above him. Already in the dim light through the windows Darren could see the colours of the liquids in the vials changing, and he could feel the warmth of his body radiating from his own chest. Both men were so involved in their admiration for the others body, neither heard the classroom door open and close. Both let out a yelp as the lights flicked on, dazzling eyes that had grown used to the dimness. "Is somebody in here? I didn't expect- Oh my God!" exclaimed an unfamiliar voice. Darren stepped back from his father, morbidly aware of his cock tenting his sweatpants, noticing his father's own huge erection emerging from the bottom of Lawrence's tight basketball shorts. He turned from his father's huge hairy form and looked towards the door. There he saw his Chemistry professor, Mr. Jones, standing at the light switch, staring in awe and confusion at the two men in his classroom. 'Two Giants' corrected Darren in his own mind. He tried to calm himself, tried to think past the rapid beating of his heart and the answering throbbing in his sweats. The three men were frozen in tableau for a moment more, before Mr. Jones stepped away from the wall, walking slowly towards Darren and his father. "Darren? Is that you? I-it can't be? What on earth happened to you?" Mr. Jones transferred his gaze to Darren's father, eyes widening somehow even more as he took in the heavily furred, obscenely muscled torso of Lawrence, eye's flicking down and then back up. Darren watched Mr Jones' face flush as he swallowed and tried not to stare at Darren's fathers cock. "Darren! What is happening here. I demand an explanation!" "Mr. Jones, I can explain. You see I, we-" "Darren," interjected Lawrence smoothly. "Is this one of your instructors? Aren't you going to introduce him to your old man?" Darren turned in surprise, giving his father a quick glance, returning the nod he received. "Yeah, sorry Dad, of course. Mr. Jones, I don't think you've met my Dad before have you? This is Lawrence. Dad, this is my chemistry professor, Mr. Jones." Darren stepped back at a loss as his father stepped forward to shake hands with Mr. Jones as if they were meeting by chance on a stroll in the park. Mr. Jones looked no less shocked and bewildered, but the ritual pleasantries were a lifeline he could cling to for a sense of normalcy. Mr. Jones stuck out his hand only for Lawrence's massive mitt to completely engulf his hand and wrist in a gentle grasp. "Nice to meet you Mr. Jones. My son here has told me about you, says he really enjoys your classes. Never mentioned you were so handsome though. What brings you in so late?" Darren stared in surprise at his Dad, flabbergasted by how calm he was being. Darren thought he must be trying to flatter the smaller man, but from the look on Lawrence's face Darren suspect his Dad really did find Mr. Jones to be handsome. "Ah, um, nice to meet you Lawrence. I'm H-Harold. Harry." Darren watched Mr. Jones look between himself and his father, and wondered just how much of their activities Mr. Jones had witnessed. Judging by the bulge in his pants, he wasn't turned off by the sight. "Harry? Really? Bit of an ironic name isn't it? You make bald work for you though, and I like the moustache." Darren's Dad continued to hold Mr. Jones' hand, smiling down as the smaller man grew more flustered. Now that he really paid attention, Darren supposed that Harry Jones really WAS a handsome man. He just hadn't considered being interested in an older man before, until... well, a couple hours ago. Mr. Jones pulled his hand free of Lawrence's grip, and looked towards Darren again. "Darren! What is going on here! What happened to you? How did you get so, so," Mr. Jones floundered. "So huge! Why are you here and dressed like..." Mr Jones gestured helplessly up and down at Darren and his Dad. He even seemed to sigh in exasperation as he noticed both men were barefoot in a chemistry lab. "Mr Jones, I can explain. It's kind of a weird story, but..." "Darren, why not stop confusing your teacher, and just Show him what happened instead?" Darren blinked and looked at his father in surprise. Lawrence just grinned at him, and carefully pulled a glass container of faintly blue liquid from between his pecs. Harry looked flummoxed and slightly turned on as he watched the vial emerge from between two enormous pillows of muscle. "My son," Lawrence said proudly, "created the greatest experiment in the world today. I was his first test subject." His father flicked the stopper from the vial with his thumb and slowly lifted the glass, flexing his huge arm for show as he took a small sip of liquid. He sighed happily, and Darren felt his cock throb in excitement, the familiar sensation of butterflies filling his stomach again. He looked down at his teacher and laughed, rubbing the back of his head, flexing his own bicep as he tried to enjoy having an audience. "Sorry Mr. Jones, I guess I'm a better scientist than I thought. You might deserve some of the credit though." Whatever Harry Jones was going to say in reply was lost, as both he and Darren turned at a loud groan from Darren's Dad. As they watched, Lawrence lifted both arms up, pointing and posing like a classical statue. His huge muscles flexed, seeming to grow larger. Darren heard a gasp from Mr. Jones as his father began to inch slowly upwards, body creaking and groaning as he put on height and weight. His dad switched poses twice more, ending with a most muscular as his growth topped out at about six inches. Darren found himself having to look up slightly again at his newly eight foot six inch tall father. He grinned up at Lawrence. "Looks like your second puberty isn't quite over yet Old Man," joked Darren. "Hey, watch who you're calling old, shorty. Or your Dad will send you to bed with no supper." Lawrence winked down at Darren and shook the vial of blue liquid meaningfully. He then transferred his gaze to the awe struck shorter man before him. Darren stepped out of the way as his father knelt down in front of Mr. Jones. "So what do you think Harry? Do you approve of my sons genius?" Lawrence winked and flexed one massive bicep in Mr. Jones face. "Why don't you give it a feel?" Darren grinned as he watched his entranced teacher reach out and rub one hand tentatively over his fathers arm. A big flex from Lawrence encouraged the smaller man to touch and feel the tricep and forearm, even trying to wrap his small arms around Lawrences bulging muscles. "My god, I must be dreaming," breathed Mr Jones. "None of this can be real. You- You're huge! And hulking and handsome and, and..." words failed the smaller man, and Darrens father winked. "Well thanks Harry, I think you're pretty handsome yourself. By any chance has a cute little man like you ever dreamed of being a Big Man like me before?" Lawrence smiled, and Darren felt his stomach do flips of excitement. "W-what? What do you mean, me? I- I couldn't. None of this makes sense, we don't know what's happened, we don't know if you're safe or, or, or any of a hundred other things." Mr. Jones was looking up at Darrens father in both confusion and lust. Darren saw his knees wobbling and stooped to try to catch him, but Lawrence was there first, picking the smaller man up and setting him on a long counter. Darren's father then reached out and casually plucked the vial of liquid from between Darrens pecs, giving his son a wink and knowing nod before turning back to Mr. Jones. "Harry, you're over thinking this. The question is simple. Do you want to be big like me?" Lawrence said, bouncing his pecs in the smaller mans face. "Because if you do, you just have to drink this." Lawrence held up the half empty vial of green liquid, wrapping Mr. Jones' hand around it, helping him hold it steady. Darren watched Mr. Jones swallow and close his eyes, breathing deeply. Taking a deep breath of his own Darren realized how musky and warm the lab classroom had become, the scent of him and his father's huge bodies and throbbing erections permeating the space. He found it intoxicating and knew it must be having an even stronger effect on his chemistry professor. Mr. Jones seemed to come to a decision, opening his eyes and looking up at Lawrence's smiling face. He held the vial to his lips, hesitating. Darren's father reached out with one finger and gently tipped the glass vial up, green fluid flowing into Mr. Jones mouth. The smaller man drank the whole vial, not spilling a single drop. He then sat on the countertop, breathing deeply, and gave Lawrence a worried look. "What did I just- ungh." Mr. Jones bent forward, holding his stomach for a moment. He slowly straightened back up, a weak grin on his face. "Sorry about that, I almost believed you for a moment..." said Mr. Jones, trailing off as his eyes became unfocused. Darren moved up next to his father, eager to watch the growth process again. His father slung one heavy arm across Darren's broad shoulders, the other still supporting Mr. Jones. 'Harry' thought Darren. 'I think I'm going to have to get used to calling him Harry.' Harry meanwhile was beginning to sweat, eyes still unfocussed. He let out a low moan, leaning back against Lawrences supporting hand. Darren grinned eagerly as he watched the crotch of Harry's pants begin to swell and grow. The imprint of an impressive cock began to show through the fabric, two egg sized lumps developing below. Harry gave a sudden gasp, looking down in shock at his crotch, then back up at Darren's father. Lawrence smiled and gave Harry a nod, then gestured down at both his and Darrens own impossibly swollen junk. Darren just winked and reached out to pat Harry's shoulder in support, then reached down to pat the smaller mans rapidly swelling bulge. A soft groan emerged from Harry's lips, turning into a louder moan as the snake in his trousers extended down his pant leg, and the bulge of his testicles threatened the seams of his trousers. The swelling didn't stop, and soon a loud popping sound announced the surrender of Harry's zipper. Darren and his Dad both tensed in excitement as they watched two large nuts emerge from Harry's pants and roll onto the countertop. The rapidly swelling orbs grew from the size of oranges to grapefruits and beyond while the log in Harry's pants throbbed and flexed, swelling up thicker and harder. Finally the cock tore free of Harry's trousers and rose up to smack against the smaller mans chest. Harry's look of shock and excitement made Darren grin, and he looked to his father and grinned wider to see the hungry look on Lawrences face. Darren watched his father retrieve the blue vial from its pectoral prison. His father took another swig of the serum, then held the vial in front of of Harry's face. The smaller man eagerly tipped it back, nearly emptying the glass. He was prevented from doing so though when his own own throbbing erection knocked the vial from his hands. Darren caught the vial before it could be smashed, and gazed hungrily at his father and Harry. Lawrence had one huge hand at Harry's back to support him, while the other hand stroked the nearly four foot long erection the smaller man was sporting. Harry's cock had grown so hard it was in danger of hitting his face if Lawrence wasn't there to fend it off. Darren felt his own cock stretching out his sweatpants. The heat in the room grew more intense as all three men grew hard, breathed harder. Darrens father guided Harry's cock up and between his pecs, moaning with Harry as the massive log throbbed against Lawrences sensitive chest. Both men were beginning to stretch taller, and Darren enjoyed the contrast between his huge, hulking father, and the increasingly lanky limbs of Harry. Harry moaned and groaned as he fucked Lawrence's chest, and Lawrence let out a booming laugh as he hefted Harry's watermelon sized nuts with his larger and larger hands. Darren stepped back as his own cock tore free of his sweatpants, the fabric puddling around his ankles. He grabbed his cock as it throbbed against his chest, eyes glued to his father as the man grew past nine feet tall. Harry seated next to the counter couldn't be far behind. "Hey Dad, who do you think is taller?" "Fuck son, I don't know who's taller, but I know who's Bigger!" said Lawrence, rubbing Harry's throbbing cock. As if to prove the lie, Lawrence's basketball shorts chose that moment to tear around the swelling globes of Lawrences ass and the even larger melons of his nuts. His fathers gigantic cock swelled upward, rising in a graceful arc to thump against his chest next to Harry's. "Well I'm still bigger in most ways anyway. Maybe it's time to fix that," boomed Lawrence. Darren watched eagerly as his growing father pulled the increasingly small final vial from between his pecs. The big man fumbled with the stopper, fingers too big and clumsy to pull it free. Finally he used his teeth, swallowing a mouthful of pink liquid as he did so. Lawrence then pulled Harry to his feet. The two men were of equal height, but where Harry was slender Lawrence was built broader than a barn, and much more muscular. Darren watched his father pull Harry into a deep kiss, then pour the remainder of the pink solution down Harry's throat. As the two giants crested ten feet of height, Darren watched both their muscular bodies tremble and then FLEX. His fathers muscles swelled and bounced, fighting for space on his frame as the already prolific masses grew ever more impressive. Harry's muscles however Exploded onto his body. Huge heaving rolling masses of sinew and steely fibres rose up under his skin. The almost Fey skinniness vanished in moments as Harry morphed into a hulk to match Darrens father. Biceps grew from baseballs to bowling balls to basketballs into bloated beach balls of muscle. His triceps expanded on the back of his arm, rubbing against newly forming lats that forced his arms to higher and higher angles. Darren shifted position, the better to watch Harry's back expand into a broad "V" shaped taper. His narrow waist thickened, but the incredible growth of deltoids and traps more than compensated. Great rolling plains of muscle erupted from Harry's smooth back, the symmetrical foothills crisscrossed by great cables of sinew and thick pulsing veins delivering more power and more growth into the expanding hunk. Meanwhile Harry's ass rose up, becoming perky, then solid, then almost obscenely curved as the two globes bloated with lead heavy mass. Darren felt his cock throb and gush with cum as he watched Harry's ass expand, driven by need to press his own rod between those cheeks. He stepped up behind the giant man, wrapping arms around him, and pressed his own cock between those cheeks. His dick throbbed between his pecs, against Harry's back, and between Harry's huge ass cheeks. In response, Harry began to buck his own hips against Lawrence, his own moans growing deeper as he continued to grow broader. Darren felt the growing mans huge nuts swing between thickening thighs to slam back against his own orbs. Darren let out a wordless yell as his cock throbbed and shot load after load of sticky cum across Harry's growing back. His voice was joined by Harry's new deep voice, and the even DEEPER tones of Darren's Dad. Darren realized he had to look up to see the back of Harry's head now. The colossal muscles of his traps had swallowed his neck, expanding out towards impossibly broad shoulders. The muscle giant in front of of him was breathing extremely heavily. Darren looked up as a wet drop of something landed in his hair, then again onto his chest. The ceiling above the three men was coated in thick heavy cum. Darren also noticed the ceiling was much closer to Harry's head than his own. Staggering backward, Darren bumped the long counter with a crunching noise. He couldn't help laugh at how easily the stainless steel bent under his mass. The two looming studs in front of him turned at the sound, and Darren felt his jaw drop. Harry's back was broad and impossibly muscular and beautiful. The front of his torso however was a masterwork of bloated, powerful muscles, bouncing and throbbing as they fought each other for space. The thick veins pumping power across the masses of muscle were receding, settling down under the smooth skin. Harry's face had grown more rugged, his jawline even more pronounced, and his bald head gleamed under the bright lights, glistening with sweat that collected in his thick moustache and shimmered. Darren's Dad was a perfect contrast to the smooth hulk, a hirsute colossus of rippling perfection, thick beard and thick hair slicked with sweat and cum. The two men loomed over Darren, both of them ten feet tall, each one having to weight at least a ton. Darren felt his cock lurch to extreme hardness again, a response echoed in the other two studs as their cocks thumped against their powerful pecs, huge swollen testicles bouncing against their thighs. The two mature muscle giants grinned at each other and then down at Darren. "Hey son. What are you doing down there?" boomed Lawrence, voice even more resonant as it echoed from his chest. "Just admiring the view Dad. How's the new perspective?" "Pretty fucking great son." Lawrence lifted his arms up into the most enormous most muscular pose ever performed, huge chest forcing his arms apart as it swelled with mass. Next to him, Harry let out a shaky laugh, still learning how to move his thighs around each other, clearly still dizzy from his new libido. "Darren. Lawrence? Did that really happen? I have to be dreaming," spoke the newest member of their muscular family. "Not dreaming at all Harry," said Lawrence as he slung his arm across the new giants massive shoulders. "Could a dream do this?" he said, planting a kiss over Harry's lips while flexing both his massive biceps to either side of the giants head. Darren watched enviously as the two massive men embraced each other, grinding hips together, enormous muscles dancing, colossal balls swaying between their thighs. Darren bit his lip as his cock throbbed urgently again, wanting release as he beheld the monstrously muscled men before him. His hands flexed, and he became aware of a small glass vial still clutched in his palm. He held it up, realizing it still contained a single mouthful of blue liquid. Darren grinned. "Dad. Hey, Dad!" Unable to get the attention of the giants, Darren strode up to them, sliding his arms between their sticky torsos and with enormous effort prying the two horny muscle giants apart. Darren held up the glass vial to forestall their complaints, and Darren's Dad grinned down at him. "Ready to join your Old Man up here then short stud?" asked Lawrence. Darren smirked up at his dad, handing him the vial. "Nah Dad, I'm pretty happy with my new perspective. But I think yours could use a little more adjustment." Lawrence looked down, at a loss for words as Darren pressed the glass into his palm. Lawrence looked across at a beaming Harry, then down at his grinning son. "You sure boy? We don't know when we'll be able to make this stuff again, or even if. You sure you don't want to join us?" "Oh, I won't ever be leaving you Dad. But I'll be happier down here, and we both know you're going to be happier up there," said Darren, pointing at the ceiling a few scant inches above Lawrences head. "Well then, I won't ask again," smirked Lawrence. "Bottoms up!" The huge muscular man drained the last of the vial in a single swallow, tossing the glass aside with a small crash. He then reached out with two enormous arms, pulling Darren and Harry into a massive, crowded hug. All three men felt their cocks throb in anticipation, and they didn't have long to wait. Darren felt his Dad's bulk stretching upward again, enormous furry chest pressed against Darrens face. Harry's smooth bulk moved up behind him, giant cock and heavy balls rubbing against Darrens back and ass. Darren pressed his face against his fathers flexing pecs, feeling them stretch larger while he listened to his father moan and groan. A dull thump and the crack of ceiling tiles announced Lawrence rising to his new height of ten feet six inches. The giant muscle man bent his knees slightly, leaning forward, chest to chest with Darren to plant a long slow kiss on his son's lips. He then reached forward, pulling Harry's lips to his, crushing his son between titanic pecs, gargantuan cock throbbing against Darren's torso. Darren smiled and breathed deeply of his fathers musk, as his new muscular family closed around him. "I love you Dad." "And we love you" rumbled two deep voices.

Like Father, Like Son Part Two "So, you ready to grow up like your old man?" Darren blinked, once, twice, three times. His fathers grinning face, surmounting two enormous hairy pecs, swam in his vision. Lawrence picked up one glass container between two fingers and wiggled it in front of Darren. "Hey Darren. Earth to Darren here. You want to keep your old man waiting? I'm not getting any younger, but if you don't say something soon, I am going to start getting Bigger!" Lawrence laughed as Darren snapped out of his fugue. "Fuck yeah Dad! I want to be just like you, if not even bigger!" said Darren in an excited rush. He reached out again to grope his father's chest, his hand looking small on the thick muscular pec. "That's right you do," said Lawrence, bouncing his chest. "But I don't think you're going to getting bigger than your old man. But let's see how you do!" Lawrence winked down at Darren and then gently tipped the glass, carefully pouring the solution into the second container. The pink and blue liquids merged into a light purple concoction. They both watched to make sure not a drop was spilled, and Darren picked up the now full container. "Bottoms up!" said Lawrence, pulling from behind his back the third and final glass, containing a pale green liquid. He clinked beakers with his son and tossed his head back, draining half the glass before wiping his satisfied smirk. Darren stared at his father for just a moment longer, before tipping back his own glass and chugging the combined formulas. He set down the glass and looked at his father expectantly. Darren wasn't sure what sensation he anticipated, but when it came he couldn't help but moan. Darren first felt a light heat radiating from his stomach, suffusing his body with a pleasant tingling. His brain felt dizzy, almost as though he were pleasantly buzzed. Then the tingling sensation in his neck and shoulder began to grow more insistent, becoming an itch. Then becoming a throbbing almost-pain. The pressure on his neck and shoulder built, making Darren gasp, and he tried to stretch and strain his neck, twisting to look at his shoulder. As he watched, the feeling intensified and suddenly his neck throbbed and BULGED as the trap muscle on that size inflated. The feeling was near indescribable as his skin stretched, feeling like a water balloon full of lead was growing on his neck. His shoulder followed, swelling up into a striated ball before the growth spread lower. Darren's upper arm tingled, then filled with a fire like liquid steel as his muscles and tendons tensed and swelled. He felt themthrobbing, and growing against his bones. Bones that were lengthening, growing denser, stretching to accommodate new size and mass. Darren looked up at his father, panting, sweat running down his face. His father was watching Darrens arm intensely, grinning lustily, and Darren felt an answering grin appear on his own face. The bloating sensation traveled down from his bicep into his forearm, and he lifted his hand, watching his limb stretch and swell to double it's former length. It seemed almost twig-like, until snaking cords of muscle began to rise up, wrapping and folding over themselves as they grew thicker and more powerful, enlarging his forearm until it was bigger than his thighs. Darren felt himself leaning to one side, the new weight of his arm pulling his whole body to the left. He tried to sit up straight, but didn't have the strength to support his own muscles. The thought was so incongruous Darren began laughing helplessly, in between gasping for breath, trying to draw air into a chest that was becoming too heavy for him to lift. Suddenly Darrens right foot cramped and twisted. He yelped as the feeling turned into an icy burn, numbing the pain, but he could still feel the bones of his foot shifting, broadening, growing longer. He looked down and watched his right foot inflate, becoming wider and blockier, fully twice the size of his left foot. He briefly wondered what shoe size it might be, before the icy coolness flowed up his shin. The chilling effect transformed into burning heat as his calf began to balloon, and again he felt as though his skin was stretching over hot lead. Huge veins and muscular cords stood out as his calf bulged larger than his head, the pulsing snakes of blood and cords of sinew rising up, over and around his kneecap, stabilizing it as his thigh began to swell as well. Darren felt himself lifting, rising up on his seat as muscles throbbed and bulged in his thigh, causing him to list even farther to the left. Tipping further and further, until the chair he was sitting on slid out from beneath him. Falling to the floor, Darren felt large hands grip him beneath the arms and lift him into a sitting position on. His father was moaning up above him, and for a moment Darren thought his Dad might be hurt, or think that HE was hurt. Then, Lawrence's hands shifted, one hand staying on Darren's monstrous and powerful shoulder, the other reaching to grope Lawrence's underwear. Darren was temporarily distracted from the feeling of his other foot starting to go numb and swell by the swelling in his Dad's underwear. Seated on the floor, between his fathers own redwood thighs, Darren was at the perfect level to witness his fathers nuts bounce and churn, beginning to inflate inside his underwear. The two orbs were already larger than the average mans but now they were swelling up to the size of oranges. Then grapefruits. One large nut escaped the leg hole of Lawrence's underwear, and Darren gasped lustily as he watched that orb stretch and pull on his fathers sack. Darren braced his massive left hand on the ground, using his right hand to grip his father's thigh and pull himself closer. Darren shoved his face against his fathers huge nuts, feeling the silky hot skin against his cheek, heady musk wafting into his nose. Above him his father groaned, Lawrence shifting and bucking his hips in the chair, grinding his swelling underwear against his son's face. "Oh fuck. Oh fuck yes Darren, that's it, worship your old mans nuts. Fuck they feel so big. I'm so big! How big is your fucking Daddy, son?" his deep voice boomed from above. As he spoke, Lawrence lifted his hands behind his head, and slouched in his chair, leaving his lap exposed to Darrens worship. "He's so, BIG," moaned Darren, licking his fathers nut as it throbbed larger against his face. "Your the biggest man and best Dad in the whole world..." Darren trailed off as he gasped, the fiery feeling in his thighs driving all though from his brain. Thick, powerful muscles filled his legs now, and his ass was beginning to inflate inside his own underwear. The sensation was unimaginable and forced Darren to lean against his Dad's thighs for support while his whole body trembled. Darren's ass filled with iron hard muscle, lifting his seat even higher, thick cords of muscle spreading up his back. He felt his core begin to tighten, and reached down with his right hand to rub his emerging six pack, each ab lightly dusted with hair, the grooves between the muscles growing deeper with every flex. Suddenly Darren felt his back explode outward, both shoulders broadening, one slender, one freakishly muscled. Darren was aware of them forcing his fathers knees apart only vaguely, as the spreading of Lawrence's legs wider pressed his cock and balls harder against Darrens face. Darren laughed, feeling power flow up his back. Huge, HEAVY slabs of muscle erupted across his shoulders, neck buried in engorged traps. His strong abs and powerful core supported the new wingspan, and he felt his arms lifted up and out into new amazing angles by the spreading of his lats. But his focus now was on the rising cannon about to burst out of his fathers underwear. Cantaloupe sized nuts pushing firmly against his chest, Darren leaned forward, placing his right hand on his fathers growing tool. The black cotton of Lawrence's underwear finally tore away, waistband snapping off as his Dad's nine inch cock began to bloat and thicken, catching up with the amazing testicles below it. Darren watched as both his hand and his fathers cock swelled up bigger, huge veins bulging out of both. He squeezed his fathers dick, feeling his grip strength increase as his forearm thickened. Above him he heard his Dad's moans and grunts get louder. As his right arm bulked up into a powerful series of bulging muscles, Darren could resist no longer, and guided his fathers growing cock into his mouth. The taste of his fathers cock was heavenly, sweaty, salty and musky. Darren groaned lustily around the shaft of his fathers expanding cock. He realized that his Dad wasn't hard yet, that some part of the growth process was holding the old man back. All the swelling in Darrens mouth was entirely due to the increasing heft and scale of that tool. A fierce new flaming and throbbing sensation began in Darrens stomach, and he tightened his abs up in excitement. The burning bloomed upward, moving as a wave of heat into Darrens still flat chest. He leaned even harder against his father, pressing his chest into those massive testicles as he felt his chest begin to pump. Throb. Flex, and grow. Darren moaned around the rapidly inflating cock as pecs, two enormous and heavy masses of muscle erupted from his torso. The weight was incredible, the strength to carry the mass even more so. He flexed and bounced his chest as the muscles swelled and stretched without end, grinding them against his father's nuts. At the same time he felt his fathers cock begin to stiffen, growing harder in his mouth. Darren's head was forced backward, only the insane growth of his chest keeping him in contact with his fathers cantaloupe sized balls. He lifted both hands to that rod, each finding space on his fathers increasing length while Darren continued to lick and suck on the tip within his mouth. He felt his jaws forced wider and wider, until with some panic he finally had to pull his fathers cock head out of mouth. He was just in time as the enormous muscular length thickened until Darren new that even a giant like himself couldn't hope to fit that flared head in his mouth. 'A giant like himself.' The though stopped Darren for a moment, and he realized it was true. His huge hands pressed against his fathers thighs were attached to forearms bigger than the bole of a tree. Soccer ball sized biceps pressed against a chest that contained more muscle than his entire body had that morning. Boulder shoulders stretched away from his face as he stretched his thick neck left to right. Cobbled abs led down to skintight underwear that seemed laughably small to him, like he'd shrunk them in the wash. His massive thighs rubbed against each other pleasantly, and he could feel his huge calves flexing and grinding against his even more massive ass as he sat on his knees. An insistent throbbing and a flood of musky pre splashing across his broad hairy chest brought Darrens attention back to his fathers mammoth cock. Two heavy hands thumped onto Darrens shoulders, and he felt his fathers powerful grip rubbing and probing the muscles, while pulling Darrens face insistently against his Dad's cock. Darren was happy to oblige, stroking his fathers enormous length with one hand while the other squeezed and kneaded Lawrence's heavy balls. HIs tongue bathed the head of his Dad's mighty cock, and he slurped up the gushing torrent of cum as he felt his fathers body seizing and spasming above him, growing closer and closer to release. Suddenly, a rugged hand was gripping his chin, forcing Darren to tip his head back. Those fingers prized his mouth open, while a second hand brought a glass container to his lips. Understanding dawned in Darren, and he brusquely seized the glass from his father, pouring the liquid down his throat before throwing the vessel away with a shattering crash. He turned his attention back to his father and shoved his face between Lawrence's two heavy musky orbs. He licked and worshiped those hairy nuts with his tongue, feeling his fathers hand on the back of his head tangled in his wavy hair. The burning heat in Darrens stomach, nearly receded, crested suddenly to a new intensity, and he felt burning tendrils of magma pumping their way down his abdomen and deep into his scrotum. He gasped and moaned, body tensing and flexing uncontrollably as liquid lead poured into his balls. He felt the skin of his sack stretch to bursting, and then continuing to grow tighter, more taught against the swelling mass of his testicles. The cool floor made him sigh when his nuts touched ground, filling the space between his thighs, making him shift his legs further apart to make room. The desire to cum, to climax, to relieve the pressure was intense, but the pressure only continued to build. He felt his own average cock began to snake outward from his abdomen. The weight of it was surreal, the sensation of his cock growing longer, thicker, and plumper without ever getting hard was impossible to describe. Above him he could feel his fathers cock jerking and spasming, a rain of burning droplets across his broad back telling him his father was cumming. The desire to join his Dad forced his cock even larger, and fhe finally felt the intensely sensitive skin of his dick stretching and firming up, his shaft rising higher and higher. His cock thumped against each set of his abs, and somewhere in his mind, a part of his brain that was free of the haze of hormones and pheromones wondered just how BIG he was going to get. Darren got his answer when he felt the tip of his cock tickling the underside of his enormous pecs. The sensation made Darren cry out in his much deeper voice, and he grabbed his cock with one hand, eyes going wide as he felt it continue to swell, fighting his grip. Unable to control himself any longer, Darren rose up unsteadily to his feet. Standing took much longer than he though it should and his new vantage point was dizzying, but Darren focused his horny thoughts on his father below him. His old man seated on a chair, head leaned back, hands rubbing his cock and abs as Lawrences own massive cannon relaxed to half mast. Darren grabbed his father by the shoulders and thrust, driving his cock up between the mounds of his Dad's chest. The tight canyon felt impossibly good around Darrens cock, and he began to buck his hips, feeling his nuts sway wildly and collide with his Dad's own cock. The chest muscles around his dick began to flex and bounce, driving Darren wild as the nerves in his cock sent signals of impossible pleasure to his brain. Darren couldn't take anymore, and he felt his body tense and his enormous nuts draw up, before his cock burst. A geyser of thick cum erupted from the tip, splashing against the ceiling and raining down on the two of them. Darren bucked and thrust, grunting and moaning as he climaxed, powerful energy suffusing his entire body with a feeling of bliss. The kitchen chair beneath his father gave way and collapsed, and the two giants tumbled to the floor. Grinding their massive chests together, still feeling his cock trapped between his fathers pecs, Darren leaned down and planted his lips against his father's. The bristles of his fathers beard scratched against his own pronounced stubble as he made out with his father, hands roaming and exploring that impossible body as his fathers hands squeezed and groped his own muscular back. Both their cocks rose up again, and the two of them felt their nuts contract simultaneously, and they blew thick sticky loads of cum between their hard muscled bodies. After what felt like hours, the two of them lay gasping on the kitchen floor. With a groan Darren rolled himself off his father. Their bodies made a sticky rasping sound as they pulled apart, and Darren felt his back land on the blessed coolness of the kitchen linoleum. He lay there, panting, staring at the mess on the ceiling, watching his pecs rise and fall out of his vision with every shuddering breath. Deep breathing from the radiant heat source beside him confirmed his father was also in need of a rest. Darren wasn't sure how long he lay there before he felt his fathers hand grasp and squeeze his own, the pressure immense but pleasurable to his newly strengthened body. "Darren?" "Yes Dad?" "I love you son." "I fucking love you too Dad." Darren began to chuckle, enjoying the bassy sound of his new voice. His father began to laugh too, and the two of them laid in the hot kitchen catching their breath after the growth they had just experienced. Darren heard and felt his father sit up next to him, and rolled onto his side, propping his head up on one massive hand. Darren admired his fathers heavy silhouette, and he reached out to rub his hand over Lawrence's bulging tricep. His Dad looked back down and grinned at him. "I think we made a bit of a mess son." He gestured at his cum soaked torso, then waved to include the ropes of sticky seed covering the rest of the kitchen. "Looks like that last drink did more than just grow our dicks. I've never felt myself cum so much. Or felt so Virile!" His dad lifted an arm to flex his bicep, then lifted it even higher, taking a whiff of his own arm pit. He made a gross face, but then grinned and leaned in to take a second deeper breath before letting his arm drop. Lawrence scratched his chest, making the muscles of his arm dance. "I don't think anybody has ever felt like us Dad," spoke Darren. "Let alone smelled quite as musky as we do." Darren groaned and sat up, a look of surprise crossing his face as he felt how strong and supple his core was. It was pleasantly easy to lift all the mass of his torso. He watched his father stand up and stretch our a hand to help Darren up. Darren enjoyed the view of his father enormous bare backside, then let out a gasp as his father turned. "Jesus Christ Dad. I knew you grew big, but I didn't realize just how much!" Lawrence looked puzzle, hand still outstretched. When he looked down at his cock swaying by his knees, he let out a deep chuckle and winked down at Darren. "I'd say watch your language son, but I think we can make exceptions for a couple of muscle gods like ourselves. Besides, I'm not the only one packing more tool than he needs." Darren reached up and accepted his Dad's hand, letting Lawrence pull him up. As he stood he brushed aside the kitchen's hanging light. His father wrapped his arms around him and pulled him into a tight bearhug. Darren returned it with conviction. He loved the way their muscles bulged and pulsed against each other, and the incredible pressure of his Dad's hug. He could also feel his own cock pressed against his Dad's giant tool, and felt himself throb. Trying to distract himself, Darren experimented with flexing and bouncing his mighty chest. It took him a few attempts before he could reliable flex the muscles one at a time, but his father didn't seem to mind. In fact his Dad flexed right back, his hairier chest grinding against Darrens with enormous strength. Eventually his Dad let him go and they stepped apart. Their bodies made another sticky rasping noise, and they both broke into low pitched laughter. "Dad, I think we might need to have a shower. We're still a little sticky." "Just one shower? Son, we're gonna need to do this separately, there's no way we can both fit into the bathroom together, let alone the shower. Not that I don't want to try," his Dad said, leaning in for another kiss. "You've got a point," said Darren, breaking the kiss. "Why don't you go try first. I've already showered once today, it seems only fair. I'll try to do something about the mess in the kitchen. " "You sure you don't want to go hose each other off in the backyard?" joked his Dad, grabbing his own cock suggestively before laughing. "I think the neighbours might object Dad. Let's save that as a last resort. Or at least until after dark." "Oh, after dark. I like the way my son thinks!" Lawrence smirked. "It won't be too long before then anyway. But fine. I'll go try." Darren stood looking at his Dad, neither of them moving, both entranced with the others giant bodies. Finally his Dad shifted, strutting past Darren. Or trying too, as their shoulders collided and they both had to laugh again. "It might take your old man a bit of time to adjust to how BIG he is now son." Lawrence chuckled as he forced his way past Darren, reaching back to cup Darren's ass as he did so. Darren stuck his head through to the living room, grinning as he watched his Dad climb up the groaning stairs, huge ass bouncing with every stride. Turning back to the kitchen, Darren brought his own arms up into a flex, looking at both of them, making the muscles dance. He grinned, then sighed as he looked at the ropes of cum splashed across the kitchen. He also chuckled at the layer of dust on the fridge, now visible from his new height. By his guess both he and his Dad were equally eight feet tall now. The countertops looked so far away, and the cupboard door handles were tiny in his massive hands. He kept misjudging distances, banging doors with his knuckles, bumping walls and furniture with his shoulders. The biggest excitement was when he tried to stand at the sink and had to back up to make room for his junk. He looked down proudly at a cock nearly as big as his meaty forearm, and shifted his hips, feeling how his balls swayed. Darren became so involved with exploring his newfound size that he nearly jumped when he heard his fathers deep voice from the living room entry. "I thought you were going to start trying to clean up in here," came a stern mocking tone. "Why does it seem like things have only gotten more messy! Darren turned to see his dad gesturing at a broken vase, knocked over chairs, and a cupboard door wrenched from the wall and placed neatly on the kitchen table. "Well pardon me Dad, some of us have been adjusting to the new size that You got us into!" Darren grinned. "I wasn't the one that decided to drink unknown liquids!" His father walked into the kitchen, heavy thighs sliding around each other, hairy body glistening fresh from the shower. His dad hadn't even bothered to look for clothes, and stood there drying his hair with a small towel, muscles dancing with the movements. Darren couldn't help but lick his lips. "Well I wasn't the one that brought home unknown experimental liquids either. But I'm so glad you did," said Lawrence, stepping up to Darren and planting a kiss on him again. His dads hands exploring his torso made Darren gasp, and he tried to pull his dad in closer. "Ah ah son, none of that now. I just scrubbed up and you're still covered in my load!" His Dad's eyes sparkled. "Get upstairs and clean up. That's an order. I'll try to do something about the mess down here." Darrens Dad snapped his ass with a towel as Darren lumbered by. Rubbing his ass in mock pain, and then with fingers curious about all that new muscle, Darren made his way upstairs. He grinned as the stairs creaked and complained under him. He smirked as his shoulders brushed the walls of the hallway. He laughed as he saw telltale gouges in the bathroom doorframe where his father has clearly hit his head and shoulders. Everything felt new and amazing to Darren as he looked down at the smaller world from his new height. The bathroom felt almost claustrophobic to a man of his size. The shower barely hit his chest, and he cracked several more tiles in the shower trying to twist his body to rinse off. More tiles in addition to the several broken tiles he noticed his father had left. Eventually giving up and pronouncing himself clean, Darren lumbered back out into the hall, drying himself off with his second towel. He walked carefully down the creaking stairs, and rounded into the kitchen, towel wiping and groping his already dry pecs, and saw his Dad washing the walls with a mop. Darren laughed, making his Dad turn and grin. "Seemed like the only way to get the job done son. I didn't know we had it in us. I guess these big bodies of ours can do a lot of new things now." Lawrences smiled and cupped his big full balls again, letting them slap against his thigh. "I guess this towel might make a better cum rag than an actual cloth at our size. I'll do here, if you get that wall." Darren grinned, working behind his Dad, purposely grinding his ass into his father's at every chance he could get. He felt himself beginning to perspire again. The close confines of the kitchen combined with their more massive bodies made the space heat up quickly. Soon the pleasing scent of Man filled the kitchen, and Darren felt his cock twitching back to life again. It was his father who broke the companionable silence. "You know, I've been thinking son." "Oh? What about, Dad?" "Do you know where I can get more of that stuff?"

Hey there, first time poster, long time lurker. This is a gender swapped story of Deviantart's Morefriction's story Wrong Target from their HERS universe. Posted with their permission ofc. Hope you all like it. The lockdowns were ruining everything. All of Kyle's classes were online and he'd been laid off of his part-time job, so he didn't even have an excuse to leave the house anymore. He'd been stuck in the house with his freaking parents for months on end, while it seemed like everyone he ever knew was out in the real world enjoying their lives, finding boyfriends, making money, and living in their own apartments. And, Kyle thought, bitterly, getting the damned HIMS virus. OK, so he only actually knew one guy who'd gotten it—Liam Stilson, who'd apparently gotten so huge that the government was sending him checks just so he could afford food and a giant studio apartment within walking distance of where he worked. But it was everywhere. All over social media, guys his age were posting these crazy before and after pics of their HIMS virus transformations. Kyle had found it bizarre, at first, then somewhat grotesque. Their muscles were so huge and bulging that they were completely impossible to hide or really even to cover, not that most of the guys bothered. They were always out, plain for the world to see, and people were always staring at them like they were obsessed. And for Kyle, who had spent no small part of his college career avoiding the "freshman fifteen" with a religious exercise routine and frequent salads, the very idea of stuffing yourself like a total pig, so hungry that you couldn't even stop yourself from eating, was an actual nightmare. But as Kyle started seeing more of them, and he got used to seeing their absurd forms, something kind of clicked. There was one post where a guy was just walking down a crowded sidewalk. It was just a twenty second clip, taken from his perspective, which must have been nine or ten feet in the air, but Kyle had watched it countless times. It was something about the way the guy's immense shoulders swayed lazily from side to side with his slow, deliberate gait, the way that even through the camera you could just feel how huge he was; the way everyone on the street was staring at him, taking pictures of him, and all of them looking so strangely small. Suddenly, Kyle got it. He started following the original poster, then discovered a dozen other HIMS accounts to follow as well. He found the idea occupying a larger and larger space in his mind, and the idea that he could be one of those guys, that people might look at him that way, became an obsession. Especially considering that Kyle himself was only 5’11’’ in a very tall family. He wanted to know what it was like not looking up at people anymore. But Kyle wasn't going to catch HIMS like this. His parents had him washing his hands a hundred times a day, disinfecting anything and everything that came from outside the house, and he wasn't even supposed to go anywhere unless he absolutely needed to. His mother found the idea disgusting. Possibly because of her own 6’2’’ body, which she was always proud of, and which she loved. She disliked the idea of these men being so much taller than everyone else. As for his father? It seemed as if he wasn't much into the idea either. His father had spent decades of his life working on his own body. He was already fairly tall, at 6'4'', and the years spent working out in the gym were obvious in the way his immense muscles stretched his shirts and sweatpants he wore around the house even at the age of 54. Kyle thought that his dad simply might have felt he had no need to take his own body any further, and go through all the rigmarole that a HIMS infection could put him through at home and at work. His father was a successful man that had pretty much everything he wanted, and he didn’t want to disturb that. But Kyle soon found a solution. After following countless links and reading countless discussions of other men who wanted to catch the HIMS virus despite the government's restrictions, Kyle found a man selling contaminated items online, things he'd been in contact with when he'd manifested the HIMS virus symptoms. Without thinking twice, Kyle had paid the five hundred dollar asking fee, which almost completely drained his bank account. He got excited, imagining himself growing taller, stronger. He loved the idea of being even bigger and more masculine than his old man. Something he wouldn’t have thought was even possible not that long ago. When the package finally arrived Kyle was more than a little disgusted to find that it was, of all things, a dirty napkin. He was half tempted to throw it away, almost sure that he'd been the victim of what should have been a very obvious scam. But he'd waited so long and he'd fantasized about the possibility so much that he finally held the awful thing in his hands, then tentatively wiped the repulsive thing over his face and mouth, until there was no way that he hadn't been exposed to the virus. He even kept the stupid thing on his desk, intending to expose himself again on the following day, but it had disappeared after breakfast. “Got anything more to throw out up there bud? I’m taking out the trash!” He heard his father ask from downstairs. It was obvious that he had taken it while cleaning. That night, as they were watching an old movie together in the living room, Kyle and his mother heard his father’s stomach growl aggressively. He just smiled and turned to them. “Woah, sorry about that. Must have gotten hungry.” He said, patting his firm, muscular stomach. Which was odd, Kyle thought, because the three of them had just had dinner. After a while his dad got up and got himself a snack from the kitchen. He finished it and went up to get another. After he had finished that, he brought out the leftovers from that night’s dinner and started eating them, staring at the TV. “David,” Kyle’s mother asked, a growing look of concern falling across her face. “Are you alright?” “Oh, I’m fine, don’t worry. I’m just famished.” He smiled at her, and he passed his large hand through his full, thick salt and pepper hair, nervous. Kyle couldn’t help but glance at his father’s large bicep, as it twitched and curled into a firm ball as he brought up his hand to his head. Soon, his father had eaten almost everything in the fridge. His mother was starting to freak out. His father tried to reassure them that everything was fine, he wasn’t even feeling weird, it was just a weird hunger spell. Kyle didn’t want to believe it, but a part of his brain was no longer able to ignore just how tight his father’s clothes were now, so much more so than usual. How it seemed like, no matter how much he pulled his sweatpants down, the cuffs always kept rolling above his ankles, his shirt was riding up more and more. He saw his father eye the canisters of enhanced nutritional formula they had acquired through his dad’s friends as a precaution, never in a million years thinking that they'd ever use them, but feeling that it was better to have them than not. And then it began. His father stood up, and bent over. His stomach growled again, much louder than before. Kyle’s mother jolted up and went to the canisters, opening one up and helping his father drink from it. He gulped it down greedily, tens of thousands of calories sliding down his throat. Then he went for another canister, and then another. They all knew what this meant. At first, Kyle was too stunned, too utterly hurt by the cruel twist of fate to even say a word. He simply stood there, helplessly, as his father grew larger and larger, his cries of panic and dismay at having caught the virus soon muffled by the sounds of relentless, machine-like consumption. Kyle’s mother stared at her husband as he visibly expanded in the living room, his thighs and butt swelling, his pecs growing thicker and wider on his chest, his already huge arms packing on even more corded, hard muscle, and his entire frame growing five or six inches longer. They all had to face the reality of the situation. They were supposed to only get one canister of nutrients per household from the government, but his dad wrangled some of his old friends he knew had access to them into giving them a whole load of canisters, just in case. As she watched her husband gulp down the thick liquid greedily, Kyle’s mother regretted giving them all to him almost at once. They only seemed to make him hungrier, more insatiable, and he gulped down the oddly clear, gelatinous fluid like it was the most incredible thing he'd ever tasted. Her husband’s already enormous cock was also increasing at an alarming rate, although already standing fully erect as he drank, having long ago burst through his sweatpants like they were made of tissue paper, it too just kept growing longer and thicker. She realized, as he took another canister from her, that his forearms alone might have already become larger than even her thighs. She watched his engorged, enormous muscles twitch and twist as he brought the canister up to his height, his bicep curling into a ball the size of her chest. His jaw had become even sharper and more masculine, which she didn’t really know was possible for someone who was already so grizzled, handsome, and manly to begin with. She looked down at his waist. Somehow it remained narrow and tight even on his new titanic frame. Where David had once a solid six pack, now he sported an inhumanly ripped and bulging eight pack and Adonis belt. As she handed her husband yet another of the canisters of formula from the bannister of the staircase, as it was the only way she could match his height now, she was vaguely aware of her poor son screaming and crying from below, obviously distraught at watching his father go through such a horrific ordeal. David felt his son’s increasingly smaller fists pound ever more weakly against first his large, round shoulders, then the side of his growing, thickening chest as he kept gulping down more and more of the nutrients his wife just kept handing to him. His clothes tore and fell in tatters on the floor, he kept feeling the tiny fists impact his large, firm ass, then the side of his growing tree trunk thighs, until he felt the hits of anger, or fear, or whatever it was, just somewhere above his knee against his titanic quads which were already huge before, but by now must have been large enough to fit both his wife and son together to into only one. He must have passed the average 10 foot mark that HIMS men usually reached some time ago, he thought, as he kept on consuming more and more of the nutrients. It had only taken a few hours. A few hours of incredulity, then panic, and finally healthy doses of fear as Kyle's dad continued his seemingly relentless growth. But it was finally over. The three of them all stood there in the living room in awe. In the end, Kyle found himself staring up and up at his father, who had become one of the most enormous, hung, and muscular HIMS men he'd ever seen.

Hello all, this is my first time attempting to write some muscle growth in years, and my first time posting it here. I do hope you enjoy. Like Father, Like Son Part 1 The heatwave ground on, making the commute home uncomfortable to an almost unbearable level for Darren. Stuck in afternoon traffic on a Friday, with no air conditioning in his beat up old car, he could only roll down the windows and hope for a breeze. He grew more impatient the longer he had to sweat in the unrelenting heat. His anxiety became more pronounced when he looked at the soft cooler bag in the passenger seat. His chemistry professor had granted special permission to take chemicals off campus to work at home, but it would all be ruined if they were allowed to heat up too much. Darren had though that a bag of ice thrown in the cooler would be sufficient to get them home, but he hadn't counted on being stuck in traffic. All he could do now was hope he made it to the house before this entire weekends plan became a lost cause. Arriving home nearly an hour later, Darren peeled his sticky self out the cars vinyl seat and rushed inside, unzipping the cooler as he hastened to the fridge. The inside of the bag was lukewarm at best, the bag of ice now a bag of tepid water. The three closed containers of liquid had lost their chill. Darren placed them in the fridge anyway and slumped against the counter. He rubbed his sweaty forehead, pushing his unruly curls out of his eyes as he took a deep breath and let it out in a sigh. The semester was going well, and he was really enjoying his chemistry classes in particular. Mr Jones was an engaging teacher, and Darren really didn't want to disappoint him after he'd granted Darren special permission to take materials off campus for the weekend. All Darren could do now was hope the things hadn't warmed up too much, and that the fridge would keep the concoctions stable. Darren set the cooler bag on the countertop, and reopened the fridge to pour himself a glass of cold water from the pitcher. He drained the glass in one long swig, and emptied the pitcher with a second pour, this time sipping the cool water, trying to bring down his body temperature. He felt slick with sweat, clothes clinging uncomfortably and chafing against his flushed skin. The heat was an omnipresent pressure this month, lingering over the city and making every activity a challenge. Darren could feel his pulse in his temples as he left the pitcher in the kitchen sink and sat down at the table. He needed to write a note to his dad letting him know to avoid the three glass containers in the fridge. They weren't harmful, but he did want to take at least some safety precautions. He reached for the pen and paper on the table then sat, head pounding, and stared blankly at the note pad. His phone buzzed before he picked up the pen, and Darren had to reply to his friends about weekend plans, texting back and forth multiple times in a minute, his classmates reminding him he'd promised to go out that night. Darren sat in a dazed torpor for several minutes looking blankly at his phone after the last message was sent. Then he forced himself to rise, grimacing at the sweat imprint he left on the chair, and went upstairs to nap and shower. Hopefully then he'd feel ready to go out for the night. His bedroom was, if possible, even hotter than the kitchen downstairs. Flopping on the bed, Darren pulled off his shirt and pants, leaving him clad in only his boxers. The bedside fan moved hot air across his body but did little to relieve the relentless heat. He lay there only a few moments before giving up and with an exasperated sigh heading to the bathroom. A cool shower first, to rinse away the sweat, and maybe a long soak in a cold bath after to escape the heat. These were the things that occupied his mind as he heard the sound of his fathers old truck pulling into the drive way. He didn't give it a second thought. Darren had his shower, putting the stopper in the bath before he finished and settled in for a long soak under the cool droplets. When he turned off the water, he lay back and closed his eyes, dozing as the bath helped draw the tension and heat from his body. He heard his Dad come upstairs and rummage around in his own room, then heard the creak of the steps announcing his descent back to the living room. Darren lay still in the bath listening to the quiet drip of water from the tap, breathing calm, mind clear, when suddenly he heard an alarmed yelp from his father downstairs. Darren sat up instantly, sloshing water out of the bathtub. He scrambled up, hearing more wordless exclamations from downstairs, and grabbed a towel and his underwear. Pulling them on still wet, he wrapped the towel around his waist and rushed from the bathroom, calling out as he descended the stairs. "Dad? Dad are you okay—" Darrens voice cut off as he rounded into the kitchen and stopped, staring nonplussed at his father. Darrens dad had always been a man of average height. Salt and pepper in his hair, but with a still mostly dark beard. A build that had been athletic in his youth but become a bit paunchy as he'd gone to seed in his middle age. The view that greeted Darren now though was of his father standing in the kitchen in tight clothing, looking down in alarm and surprise at Darren from his new height of nearly seven feet tall. Darren froze, looking up in shock. Darrens eyes took in his fathers height, standing taller than the refrigerator now. His plain t shirt had been pulled up, exposing his hairy stomach, and the sleeves were now so short as to be almost nonexistent, exposing his upper arms and shoulders. His pants showed similar strain, riding up around his calves and glued to the long limbs. Darren's father Lawrence looked down at him, breathing deeply, with a good deal of alarm in his voice. "Darren. Am I dreaming? W-why does everything look so short..." he trailed off, lifting his hand and looking at his longer forearm. Lawrence took a tentative step, shifting his weight as he stood up from leaning against the counter and cupboards. He seemed to rise even higher, nearly eight feet tall, and Darren realized his father had been hunched over the counter for support. Lawrence for his part seemed to be taking his bearings, the panic in his eyes relaxing as he adjusted to his new perspective. "Is this real?" Lawrence breathed. He reached out again, placing his hand on Darrens shoulder as if to confirm the presence of his son. "Dad! What happened to you? How did you grow so– so big!" Darrens mind was whirling as he looked up at his much taller father. Before they'd been of nearly equal height at five foot eight-ish, but now his father towered over him, head in danger of brushing the kitchen light. Darren felt almost like a child again. The change in perspective was extremely unexpected. "Did you eat or drink something weird today? Are you okay? Does it hurt?" "No, I'm not feeling any pain. It was just such... such a weird sensation," his Dad remarked slowly. Lawrence's hands moved to his torso, rubbing over his body as if still in disbelief. "If I'm honest," he said, voice becoming more confident as he stood a little straighter, "it feels pretty good. Your old man has grown into a giant!" he said, a grin breaking through his confused expression. Darren took a step back, surprised by the excitement in his fathers voice. His own heart was still beating rapidly and his hands shook as he reached out to take his fathers hand. A nagging thought was beginning to form in the back of his brain. "Dad, I'm glad you're okay, but we need to know what's happening. This is fucking insane. It's really important dad, what did you do differently today. Anything at all that would cause you to– to– to grow!" Lawrence looked down, and Darren was slightly intimidated by the frown that creased his fathers handsome features. 'Handsome? When have I ever called Dad handsome,' thought Darren. "Hey, I appreciate the concern son, but there's no need to sound that alarmed Darren. I think I could really grow to like this!" His father straightened up even further, placing his hands on his hips and puffing his chest out proudly, winking down at his son. His every motion was becoming more confident as he adjusted to his new stature. "I didn't do anything odd today. I went to work like usual, came home as usual, found you hogging the bathroom as usual." His eyebrows quirked in mild annoyance. "I wanted to have some cold water too cool off from this damn heat, but somebody left the empty pitcher sitting in the sink again. So I had some of your juice instead. Not very flavourful, I don't know why you like those energy drinks. And then, I just felt," Lawrence's eyes became unfocused and hazy as he tried to remember the sensation. "I felt dizzy, like vertigo, and then I was stretching up, the sink and counter were moving away from me, and that's when I must have called out..." Darren felt a shiver run down his spine, the goosebumps on his arms having little to do with damp skin exposed to the air. Juice? He didn't have any juice, the only thing in the fridge was... And then Darrens eyes fixed on a glass container sitting on the counter, half hidden behind his father. A glass jar with a faintly blue liquid, half drained from the level it had been when he'd placed it in the fridge. Darren felt his stomach drop, and he staggered backward, falling into a chair when his knees bumped the seat. He sat there shivering as his father looked down in concern. His father crouched down on one knee, big hands gripping Darrens shoulders as he gently shook Darren in alarm. "Darren? Darren, what is it son, are you okay?" Darren looked into his fathers concerned (and handsome?) face. "Dad. Dad I think I did something stupid and it did this to you." Darren felt his face flush with embarrassment and shame. "That 'juice' you drank wasn't juice, it was a chemical I brought home from the lab. I– I meant to leave a note, to label it, to make sure you didn't drink i– it. B– but it was supposed to be h– harmless, not do this!" Darren felt panicked, his heart throbbed in his chest as he realized how careless he'd been, how dangerous it could have been for his father. "Hey hey hey," said his Dad, "it's okay son. Nobody got hurt. That was a really dumb thing you did, but honestly? If this is the worst side effect? I'm actually pretty okay with it." Darren met his fathers eyes, face slack in shock. "What, I know you've started going to the gym on campus. Is your old man not allowed to want to be a little bigger too?" Lawrence chuckled, but Darren could feel the trembling in his fathers hands on his shoulders, and knew his Dad was putting on a brave face. "In fact, maybe I should take a little more, and REALLY break some records!" Darren gasped, almost falling from his chair, but his father stabilized him. Suddenly he realized the trembling in his fathers hands wasn't fear, it was excitement! He looked at his Dad, trying to push aside his guilt and really paying attention to his father. The gleam in Lawrence's eye, the grin on his still handsome face, the nervous tension thrumming through his bigger body. Darren felt an answering excitement throb in his underwear, and was glad for the towel still around his waist. "Dad, you shouldn't joke about that. We need to get you to a doctor or something, who knows what– Dad!!! Darren cried out in alarm as his father used his longer arm to swing open the fridge door and pull out a second glass container, this one full of faintly pink liquid. His father winked at him again as he flicked off the lid with a single large thumb. "Hey kiddo, you said yourself none of this stuff was supposed to hurt right? So why not live a little?" And in one smooth motion his father lifted the glass to his (bigger) lips and swallowed half the liquid in a single long gulp. Darren could only stare in shock, his mind refusing to believe what his father had just done. He had never thought of his father as the brightest man in the world, but he'd certainly never considered him the stupidest man either! Darren opened his mouth to give vent to his fear, his frustration, anything at all, but was forestalled when his father let out a loud burp and wiped his lips with a long forearm. "Whoops, sorry son. Looks like that one just made your old man a little gassy," his dad laughed. I didn't mean to... to..." His father trailed off, a strange expression crossing his face. He sank back into a half seated position, still on one knee, the other pressed up to his chest. "Dad. Dad! Are you okay? We need to call nine, one... one... oh God!" Darren felt his terror change so something else, something tingling and exciting deep in the pit of his stomach. He saw his own nervous trembling mirrored in his father, watching his fathers shoulders shake. Shake, and Grow! Lawrence's whole body was shivering, the look on his face somewhere between regret and a strange anticipation. As Darren watched, his fathers shoulders seemed to stretch wider. His torso pushed outward, shoulders expanding and tearing the remaining sleeves oh his t shirt. The leg propped up against Lawrences chest shivered, and Darren's eyes grew huge as he watched his fathers calf muscles begin to inflate like a balloon. A heavy, bulging, muscular balloon. The tight pants cut into Lawrences skin, threatening his circulation, before the cuff suddenly tore open with a thready popping sound. The seams of his too short pants began to tear along the leg as the muscle kept growing, and growing, Lawrence's muscular calf now thicker around than Darren's thighs! Darren's eyes were drawn back up to Lawrence's face by his deep panting, his face contorted with exertion and pleasure. Darren watched his fathers neck begin to flex and flare, growing bigger, thicker, wider. Veins stood out on the muscular column, veins that descended under the tight t shirt, visible through the clinging fabric. As Darren watched, the veins throbbed. And with every pump, he saw his fathers flat chest begin to pulse. Two flabby bulges began to shift and change shape, becoming blocky and square under the fabric. His fathers pecs. His Dad had Pecs! He reached to grab his Dad's shoulder, wanting to comfort him, steady him, but Darren pulled his hand back in shock when he felt intense heat radiating from his fathers body. He couldn't look away as his fathers pecs bounced. Flexed. Throbbed. Pumping bigger and bigger with masculine muscles. The thin shirt began to fold, developed a crease at the bottom of the chest, was rolled under Lawrences exploding pecs as the meaty muscles swelled up into two enormous muscular pillows that would have any bodybuilder drooling in envy. A snapping and tearing sound announced the end of Lawrences pants, the fabric tearing free as his quads burst into enormity, huge muscles exploding onto his legs much more rapidly than the growth of his chest. Darren rocked backward instinctively for room, chair hitting the wall behind him as his father let out a series of grunts. The leg against his chest was pushed forward as Lawrence's muscles fought for space. Lawrences foot slammed into the chair between Darrens legs, breaking it and causing Darren to fall seated onto his fathers ankle. He could feel the leg growing beneath him, getting thicker and more muscular, and Darren let out a moan, feeling his crotch swell in excitement. His father was growing into a giant muscular Stud! Shame warred inside Darren against the sexual thrill of watching the worlds tallest man grow into the worlds BIGGEST man. Darren felt sudden urges he hadn't known he possessed as he watched his Dad get bigger. Better. Manlier. Lawrence lifted one long slender arm, and both Darren and his father watched the muscles writhe beneath the skin like snakes, before beginning to bloat. The veins on Lawrences neck snaked down over his shoulder, and the deltoid of his right arm inflated to the size of a bowling ball, thick striations defining the muscle. The back of his arm ballooned into a football shaped mass, then continued swelling to twice that size. Meanwhile Lawrence's bicep was enlarging, the long muscle developing into a rope, then a thick cable, then into a swollen ball of muscle that kept throbbing larger, pressing against the powerful curve of Lawrence's chest. The forearm followed suit, large veins travelling down the limb to connect with Lawrence's hands. The muscles grew thicker and more powerful, forming a large wedge, slowly swelling until his forearm resembled a holiday ham. Lawrence's hand grew even larger, fingers thick and powerful, palms covered in heavy pads of muscle. The two men were so involved in watching Lawrence's right arm grow, they missed seeing the left inflate, grow, and enlarge to match. At least until some deep instinct caused Lawrence to raise his arms into a stunning double bicep flex, letting out a deep booming laugh as he did so. Darren felt himself cum in his underwear as he watched his Dad flex. He shot a load larger and more powerfully erotic than any he ever had perviously in his life. Panting and gasping, he watched his father grin and flex his biceps bigger, until the balls of muscle had inflated to the size of melons, bigger than Lawrence's head. Darren reached out, wanting to feel those muscles, to touch biceps bigger than any man had ever dreamed of having, but was foiled when his fathers chest gave another heave and DOUBLED in size, bursting through his shirt and slamming into Darrens hand. The feeling was electric. Darren got a kick from the energy coursing through his fathers body. His hand squeezed and kneaded the bulging muscle of its own accord, and Darren felt himself become aware of his fathers thickening body hair as new dark hairs erupted, his fathers already sexy chest becoming more so as the fur thickened over his chest, abs, and shoulders. Darren couldn't see but assumed those hairs carried on down his father back. And what a back! As Lawrence continued to flex, his lats swelled up thicker and wider, pushing his already broad shoulders even farther apart. The heat radiating off Lawrences body intensified as the already roasting kitchen became an oven of heady pheromones and masculine musk. With a loud roar Lawrence flexed every muscle in his body and then collapsed over his knee. The seated muscle giant breathed like a bellows, gasping in great lungfuls of air as the veins criss-crossing his body slowly shrank, sinking into the powerful curves and swells of his father's muscles. A body nearly as wide at the shoulders as his own height. A body that dwarfed Darren and made him feel like a child. A body that fully and utterly aroused him. For several minutes Darren didn't dare to move. He remained seated on his fathers leg, trying not dwell on how amazingly Thick and Strong that leg felt beneath him, or how large his fathers foot was behind him. He watched as his father slowly unfolded the other leg, that simple motion sending the new masses of Lawrences body into a rippling, bulging dance. Lawrence slowly lifted his head from where it rested on his two engorged pecs, and weakly grinned at Darren. "Okay son. Maybe I should have thought that through a little bit harder." Darren shivered at how deep and powerful his muscle giant fathers voice had become, and detected a similar ripple down Lawrences spine as he heard his own voice. Darren watched his father carefully reach out and slide his hands under Darrens arms, and felt himself lifted off his fathers leg and set gently on the kitchen table. Darren couldn't even think of resisting, his brain fogged by hormones, pheromones, and in a deep dark place inside himself, lustful envy. His father placed one broad hand on his knee, and with a grunt lurched to his feet. Darren saw his father stagger, unused to his new mass, and reached out to steady him. Only to have his hands slam into hard, unyielding muscle that pushed back and nearly knocked him from the table. He let go, holding his breath and holding his towel over his lap as his cock sprang once again to full hardness. He watched his father, a man who so recently Darren had been slightly taller and fitter than, tower over him. Lawrence's full height remained eight feet, but beyond that he was nearly unrecognizable. The friendly face, the salt and pepper hair, the dark trimmed beard were still there, but to all this there was a new more masculine glamour. Lawrence's hair was thicker for a start. Still greying, but thicker. His beard now covered a wider and more muscular jawline. His face was still familiar, still affable, but all his features were just somehow more muscular. From the chin down, his father was an Adonis. Heck, Adonis didn't come close, he was Herculean. Broad shoulders almost six feet wide blocked the view of the kitchen behind him, supporting two arms each bigger than Darren's whole body. His large, almost voluptuously full pecs bulked out from his torso, casting a shadow over his tight six pack, nipples pointing straight down due to the incredible fullness of his chest. Pointing down towards a narrow waist that only accentuated the vast width of his shoulders. His father, Darren suspected, didn't have a "V" shaped back, but more likely a "Y" shape as his lats winged out from the strong central trunk of his torso. Darren was amused to see that somehow his fathers black boxer shorts remained intact, clinging to the broad curves of his redwood thighs. He let out a small uncontrollable giggle, clapping his hand over his mouth to keep the hysteria he was feeling firmly inside. His father didn't seem to notice, busy as he was also looking down and staring at his own body. Lawrence thrust forward one leg gingerly, and began to shift and flex the muscles in his thighs. They bulged and swelled obligingly, rocking above his powerful knee, and the calf muscle, when flexed, bulked out even more aggressively if such a thing were possible. Darren was both relieved and embarrassed to see that his father, this mountain of power and rising confidence, was also rock hard in his underwear, and one hand was trying to unobtrusively shield that bulge from his son's eyes, even as the other hand was flexing and straining, making his forearm dance. A low rumbling filled the kitchen, rattling Darren's bones. He soon realized it was his father, letting forth a low giggle that rose up into a burbling and then hearty laugh. His laughter filled the kitchen as he raised both arms again, house rattling as he flexed and posed, showing of his new unimaginable and Godly size. "But then again," rumbled Lawrence's new more powerful voice, "thinking through my actions wouldn't have made me into this! Look at your old man son! I'm a giant! A real damn muscle GIANT!" Darren looked up in awe at Lawrence, watching the light and shadow shift over his bulging muscles, showing his serrated obliques. His father attempted to look over his own shoulder, presumably to see his back, but couldn't due to the thickness of his neck and size of his boulder shoulder. "How do I look from the back son? Do I look as wide as in front?" Darren gulped as his father turned around. His back was a crazed map of shifting and folding striations. Deep valleys and large rolling plains of muscle twitched and shifted as Lawrence tried posing, gaining confidence with every motion as he rapidly adjusted to his new mass. But Darrens eyes were drawn inexorably to the large and powerful globes of his fathers ass. Before his Dad had been just as flat in the back as Darren, but now his ass was huge and powerful, flexing deliciously inside their tight black cotton confines, the expanse of glute visible above the waistband and from the sides dusted with the perfect amount of body hair, as was all of his fathers back. His father turned around again, face excited as he looked down into his sons eyes. "Well Darren, don't just sit there staring! Tell your old man how he looks! In fact, get up here and give me a hug!" Before Darren could voice a word in protest his fathers large arms swooped down and lifted him up into the most powerful, most masculine smelling bearhug he'd ever experienced. Thick hairy pecs pressed against his face, alternatively rock hard or firm yet yielding as his father flexed and relaxed. Darren's body hummed with an electric thrill as he felt his fathers massive arms press against his back, crushing his legs against his fathers abs and thighs. He could also feel his fathers large erection pressing into his thighs, and knew his Dad must feel his own rock hard shaft against those cobbled abs. Indeed, his father soon released him, gently setting Darren back on his feet, huge platter sized hands gripping his sons shoulders gently. Looking up Darren saw his father blushing, reaching up to rub the back of his head bashfully. The mountainous bicep flex this caused seemed to turn them both on, if the throb Darren noticed in his fathers underwear could be trusted. "Ah, sorry about that Sport. Guess your old man is, uh, really enjoying himself. But can you blame me?" Lawrence asked, lowering his arm and making his pecs bounce, the muscles so huge and heavy they made an audible thumping noise when they flexed against each other. "Dad, I– I'm not sure what to feel right now. I mean, look at you! What just happened to you! You, you're huge! And sexy! And enormous! And i'm still just–, I mean, I'm stunned!" Darren finished somewhat lamely, trying to hide his envy as he looked up at the biggest, most massive man in the world. He'd been attracted to men his whole life, but never like THIS! He didn't know if he wanted his father, or wanted to BE him, and the confusion was taking a toll on his mind and body. The shaking in his hands was infecting his whole body, and he crossed his arms and sat back into a chair, trying to control his shivering. His Dad meanwhile was still looming above him, and he could hear the grin in Lawrences voice as his old man spoke. "Oh, you think your father is sexy now do you? I'd be lying if I said I wasn't turning myself on too!" he said proudly. Darren saw two fingers move into view and gently lift his chin up to look at his fathers face. "Nothing to be ashamed about son. Jealousy is a perfectly normal emotion. I've been jealous of my friend Carl's body for years, I just never had the time or commitment to go to the gym regularly and put the work in." His father flexed and bounced his pecs, grinning again. "I think Carl is going to be the one feeling jealous next time I see him though. It's going to be fun putting these muscles to use!" The whole time he was speaking, Darren couldn't help but notice his fathers erection bouncing and flexing inside his underwear. As he looked he saw a bead of pearlescent pre ooze out of the tip of his fathers shaft before being absorbed by the black cotton underwear. Darren shivered again and lowered his face, blushing furiously and clutching his aching stomach. Darren sat like that another minute while his giant Dad lumbered around the kitchen, making the floor squeak and rattle under his heavy footsteps. He heard the fridge door open, saw his fathers huge ass flexing even more hugely as Lawrence bent over to peer inside. Darren closed his eyes again, and didn't open them until a creaking groan next to him announced his father sitting carefully on another kitchen chair. Darren heard two glass thumps on the table. Opening his eyes, he saw his father looking eagerly at him. And he saw two glass containers half filled with pink and blue liquid sitting on the table before him. His eyes went wide and his mouth went dry. "So," said his Dad. "You ready to grow up like your old man?"

Longtime reader, first time posting. PART ONE Growing up, I never questioned how my Dad was so immense. I just always remember him being huge. Even in my earliest memories he was a veritable mountain. I know kids tend to exaggerate, but my Dad was absolutely massive. In our family album, he towers over everyone else. He doesn’t have his full beard yet, just some stubble on his lantern jaw. His chest hair isn’t the bear’s pelt it would later become. In the photo, we’ve moved into our house and dad is just in a stringer tank top. The photo’s just a grainy, yellowed polaroid, but still I can see the uncompromising mass in his arms, his bicep bigger than mom’s head, a finger-thick vein running down the middle, his forearms like Christmas hams. And there I am, a toddler perched on his broad shoulder. He’s got a hand on my hip to hold me there and it’s practically the size of my whole torso. Dad is 23 in the photo but already pushing 300 lbs. I’m ashamed to say I never remember him being this...small. All my memories of him are great. For his colossal size and strength, he was a caring and doting dad. His rumbling baritone was comforting instead of frightening, and he never raised his voice to Mom and I. He was quick to smile and laughed easily. Though he had a full-time job and spent most of his free time in his gym, he always found the opportunity to play with me. He’d help me build a fort in the woods and then take up the entire thing with his tremendous body. He’d read me adventure stories while I drifted to sleep on his broad chest. In one of my favorite games he’d pretend to be a bear. Snarling, he’d go shirtless, his chest and forearms covered in brown hair, and chase me about the house on all fours. I’d hit him on the head, which somehow tamed the bear, and then I’d ride on his back until bedtime. It was my favorite game until I discovered The Incredible Hulk. Dad went along as I painted my room green, covered it in posters, bought all the toys, and even talked Dad into painting himself green for my Hulk-themed birthday party. His only condition was that he’d keep his beard. I still remember a friend’s little sister crying as Dad lumbered over, gave a most muscular pose, and growled. I really can’t blame her. I was 8, so at 29, Dad must have been 6’7” and 450 lbs. His chest could stop a car and his arms resembled great knotted ropes like those used on ships. Dad’s neck was bullish and even when fully relaxed, I could spot a vein popping from it. As a kid, I just assumed all dads were gigantic. Didn’t all dads devour 20,000 calories a day? Didn’t all dads have to buy new clothes twice a year to accommodate their swelling muscles? Most of Dad’s friends were powerfully built muscle men (I would later learn he slept with half of them). I just thought that’s what men looked like. I remember going to a friend’s house and meeting my best friend’s dad, a thin wisp of a man, whom I mistook for an older brother. It blew my mind. Meanwhile, the friends I invited over were always awestruck at my dad’s sheer size and strength, something I took for granted. There were moments of jealousy as my friends flocked to him instead of me, but I soon realized I could show my dad off like a new toy. Five fifth-graders would dangle from his one extended arm. They’d ask him to crush watermelons or burst out of a shirt and he’d happily oblige. Most of the town knew my Dad (there were only a few thousand people and how could you miss a man of his stature?), but it wasn’t long before every boy in my school was talking about him like an action hero or football star. I admit I made a lot of friends that year. I did notice certain things, but I didn’t realize how strange they were until years later. For example, once a year Dad would disappear into a black van and be gone for a week. Mom always said he went to the hospital, but the men in black suits and sunglasses who ushered him into the van never looked like doctors to me. When Dad returned he would always, always be bigger and over the next few weeks he would fill out even more. He’d arrive on the doorstep with a big smile, his tank top and jeans reduced to ribbons, his toes poking out of his socks, his sneakers gone. At 10, I remembered Mom screaming in shock once she saw him. He was a few inches taller and his shoulders wider. He must have packed on over a hundred pounds. His delts, triceps, and traps looked like huge bags of flour. Freakish biceps pressed into his pecs, which were now the size of couch cushions. His quads were as big around as the trees in our yard, and his calves were bigger around than most men’s waists. Seeing him grow every year was second only to Christmas for me, but I’d have to wait before he showed me his gains. The day he came home I’d always have to go play in the yard or at a friend’s house. That was “mom and dad” time. “Mom and dad” time was right after I went to school, most days at noon when Dad would come home on his lunch break, and then at night. My parents weren’t particularly strict, but this was the one thing they couldn’t bend on. I was not to be in the house. Even at 10, I didn’t know what they did. I had my hunches, of course. Kids on the bus talked about it. It was some kind of wrestling. Now Mom was a powerhouse in her own right. She wasn’t a bodybuilder herself but she’d played rugby and volleyball in college. A friend called Mom “stacked,” which I think meant she lifted weights. In any case, she could keep up with Dad, or at least she did at first. Knowing what I know now, I can’t begin to imagine how they did the deed. I’d seen him getting out of the shower before he wrapped the towel around himself. Everything was proportionate: that is to say beyond human proportions. Maybe it was great at first. They did make me after all. I’d see her feel his arms and the look they gave each other was something I couldn’t describe at the time, but as he grew and grew and grew, it must have become too much. He needed release more often. Dad always made noises during those times, the same noises he made while working out, but over the years they became louder and more animalistic until my windows began to rattle and I thought we were having a small earthquake. One day I saw him pulling their giant bed frame to a dumpster. It was in pieces. So was a dresser and a nightstand. Things fell apart when I was 15. We’d moved to an enormous new house with vaulted ceilings, castle-sized doors, a huge yard, five refrigerators, a pool, and a basement that Dad would convert to a gym. As a teenager, I never wondered where the money came from to buy it all. I wouldn’t find out for years. Dad and I loved the place but Mom could only force a smile when I showed her how Dad wouldn’t have to duck to get through the door anymore. They started eating and sleeping in separate rooms. When Mom picked me up from school and explained her and Dad were getting a divorce, I was disappointed but not shocked. I didn’t blame her back then and still don’t. She didn’t expect her husband to triple in size. She hadn’t signed up for this. At that point, Dad was a goddamn behemoth: 7’4” and 900 lbs. His shoulders were four feet wide but the way his arms stuck out, his triceps pushed that to five feet. He started measuring his biceps in three digits, and it was a miracle he could even bend his arm. Even relaxed, those biceps resembled beach balls. One day, Dad accidentally tore the door off his truck. I remember him standing there dumbfounded, holding it as if it were lighter than a sheet of styrofoam. It took him less than a week to landscape our yard. He ripped a dead maple tree out of the earth like it was a weed, and he rolled boulders across the yard like soccer balls. How could a woman sleep with a man that powerful four or five times a day? Believe it or not, I think there was a lot Dad held back. Because once she left, his growth went into overdrive. Maybe “hospital” injections were more potent or maybe Dad had given himself permission to go all in? Whatever the reason, he quit his job as a construction foreman and devoted himself to growth. Every day a whole car full of groceries was delivered to our doorstep. Whey powders and supplements filled an entire wall of our walk-in pantry. No gym was enough of a challenge, so he had to build his own. A dozen construction buddies helped him weld a series of machines that looked like medieval torture devices: the benches were as wide as a double mattress, the weights went up to 15,000 lbs. They had to reinforce the house’s foundation. Even then finishing a set could make the ground rumble. Half a block away a car alarm would go off. Dad channeled all his sadness and frustration from the divorce into working out. He smiled less and hardly went into town, but he still participated in my life as best he could. He was ecstatic when the high school football team picked me as linebacker. Even now I chuckle at the memory of this 7 ½ foot colossus, shirtless and painted in our school colors, cheering me on at our games. I’d have friends over to the pool and half the talk centered on how gargantuan my Dad had become, especially a crotch that practically hung to his knees. “Your Dad could sit in his bedroom and fuck a chick in China,” and all that sort of thing. I laughed it off, trying to hide how conflicted I felt. Truly, I loved my Dad. I admired him and he was a great friend. But ever since puberty, something felt wrong. Friends would pass around copies of Hustler or pull up porn on their phones, but it never did much for me. While I used to stare in awe at my Dad’s column-like legs and the contours of his teardrop quads, I now cleared my throat and forced myself to look away from his dense, rotund glutes as he walked by. He’d lean over to check my homework and I’d seize up as his bare chest caressed the back of my head. Our playful wrestling came to a halt. We had the best gym imaginable downstairs but I always exercised at school, afraid the sight of my hulking beast of a dad, all pumped and sweaty would make me spray my gym shorts. We hung out less and less. I’m sure Dad assumed I was being an aloof teenager or perhaps still hung up on the divorce. We never said anything, but he gave me the space I needed. I couldn’t help but worry I was breaking his heart. Of course, I was growing, too. Looking in my bathroom’s full length mirror, I could see the beginning of my Dad’s thick jaw. I was 6’0” and 190 lbs with a stocky, muscular build. I was bulking, so the outline of summer abs had vanished, but that was fine. I was after mass. I had pubic hair but nothing on my chest or jaw. I was huge for a high school junior, but I longed for real growth. I wanted to be a leviathan like Dad. He went through so many tank tops, it was easy to take one without him noticing. The damn thing could have been a tent on me. It hadn’t been washed and some nights I would drape it over myself, breathing in Dad’s musk, imagining my naked body hulking out enough to fill the shirt, maybe even tear it. There were other guys I fancied in school. Being on the football and wrestling teams, I got to see all the biggest men working out, stripping down, washing themselves. We all jerked off together, never thinking anything of it. I don’t want to come across as vain, but because I was big for my age I got a lot of attention. Behind the bleachers, the quarterback and I sucked each other off after practice. During wrestling season, everyone was popping boners. After pinning a particularly strong guy, I realized I was raging hard. So was he. He was leaking through his lycra. Luckily the coach was distracted. We drove to my opponent’s house that night and repeated a version of our match. After watching people rub my Dad’s bulging muscles, it was strange to have someone do the same for me. Especially, since I was a toothpick next to him. In the midst of passion, my wrestler friend moaned how big my cock was. It was only ten inches, I thought. I’m ashamed to say I always thought of Dad during sex. My friends were hot, but I was always comparing their anatomy to Dad’s. It’s not fair, I know, but I couldn’t help it. When I finished on my wrestler friend’s chest, I imagined it was Dad’s mountainous pecs. I pictured them shredding out of his tank top, the striations dancing in each lobe, a forest of dark hair trapping the sweat, and the saucer-sized nipples pointing at his feet. Then I imagined my dick disappearing in his cleavage. I spent whole days locked in my room just beating off over and over, Dad’s old tank top pressed to my nostrils. I pictured him lifting the entire house, his cock rock hard as he crushed his truck into a ball of shrapnel no bigger than my head. Things only got worse after that year’s injection. With no wife to come home to, he spent a week with his construction buddies. No one will admit where the orgy took place, but we didn’t have to look far. No one was buying the “industrial accident” at a work site out of town. The explanation kept changing for how all those steel beams were bent, how entire concrete walls were leveled, and how half the surrounding trees were felled like in a hurricane. These were hundred year oaks, too. The place had a pungent ocean smell for days. Afterward, all the biggest, brawniest men in town were walking funny, though each and every one of them feigned ignorance. That whole week I couldn’t stop theorizing how much he’d grown. Each growth spurt was bigger than the last. Two hundred pounds? Three hundred? Maybe a few inches of height? The anticipation was unbearable. I felt like a little boy counting down the days before a trip to Disneyland. Bigger and bigger shipments of food had arrived in his absence and I’d spend hours putting it away. I was hoisting half sides of beef in our walk-in freezer when a knock came at the front door. I hesitated when I saw it rattle. This door was ten feet tall, six wide, and nearly a foot thick. Mom and I struggled to open and close it. From the way it shook, there must have been a battering ram on the opposite side. I opened it and couldn’t believe what I saw. A set of hairy deep-cut abs stared me in the face. I had to look up to see Dad’s colossal chest. Wider than a car, it bulged two feet over those abs. I could have buried an arm between those pecs. They rose and fell with his breath. His saucer-sized nipples were all but lost in the dense pelt of hair that now coated his stomach and shoulders. I say shoulders, but those delts were more like wrecking balls. His freakish arms hung at 45 degree angles, pushed out by lats that nearly started at his waist. Dad’s biceps were just as big as his delts, bigger even. They pushed into his pecs, fighting for space. A brachial vein thicker than my wrist snaked down the middle of his guns, and even relaxed, each head was prominent. His hairy forearms were two feet across at the widest point, covered in a lattice of veins. His hands put the Incredible Hulk’s to shame. They radiated strength. I could see them ripping train engines apart. Dad’s bare feet were just as immense, the soles caked in dirt from walking through fields and woods. It was a miracle there weren’t cracks in the front step. His calves should have been called bulls. I’m certain they were wider than a probodybuilder’s quads. Oh yes, quads. Dad’s were outlandishly developed, but I couldn’t appreciate them because they were so damn big they pushed forward his monstrous manhood and that’s where all my focus went. Look, I knew my Dad was hung, but this was something else entirely. Had they used a gamma ray on this crotch? A stretched and tattered jockstrap struggled to contain a mass that hung to his knees. Pumpkin-sized balls peeked from the open sides of the jock, so heavy they tugged the underwear down and exposed the base of Dad’s penis, itself obscured in a jungle of pubes. Alarmed, dumbstruck, and horny beyond belief, I looked up at Dad’s face and realized it too had changed. His neck had pretty much been swallowed up by his traps, though I could spot some tendons like steel cables. Stubble covered the majority of it. Dad’s hair was longer, shaggier, and though his beard was full, I could see his jaw had grown wider, bulkier. His cheekbones were more pronounced, too, not a ridiculous amount, but enough to give him a brutal, hypermasculine look. Though when he smiled, he still retained that friendly and loving demeanor. Always the gentle giant. “What’d’ya think, kiddo?” his bass boomed, deep and gravelly.

Missed Opportunity Dave a is 24-year-old college meat head who’d known nothing other than being handed everything to him in his life thanks to his charming, good looks and blessed genetics giving him the body that most guys spent their whole lives building, while he only spent a year in the gym and blew up to incredible size. He’d grown accustomed to being the top dog everywhere he went, and it certainly went to his head as many that were around him would certainly tell you that Dave was a *bit* of a douche. Yet even with all his size and charm it just wasn’t enough for him he needed MORE. So, when he stumbled on some new experimental protein shakes that were hitting the market in very limited quantities, he thought why the hell not and bought the last pack that was in stock before the site was mysteriously taken down a day later. A few weeks later all he could think about was the effects that the new shakes could have on his body and the package was scheduled to be delivered to his dorm that very day. He was ready to sprint like mad to get home and down one of the four shakes before or after his workout. But as he would soon find out it wasn’t just the shakes that he would find waiting for him when he got back home. ---- After his workout he excitedly rushed home heading down the hall ready to improve his gains even further. But as he drew near the door, he could hear noises coming from inside. His two dweeb twink roommates were surely there which already made him angry. He wanted to enjoy his post workout pump alone with no distractions. His roommates Adrian and Michael were both gay and he knew how bad they wanted him from day one, but he didn’t swing that way, although that didn’t stop him from soaking up all their adoration and teasing them with the body of a god they could never get with. Opening the door, he was met with a scene out of his worst nightmares. Adrian and Michael were grinding up on each other fully nude and they were both HUGE! “What the fuck dweebs! What happened to you two?!” The two former twinks were laid out on the couch each of them man spreading their mammoth legs completely filling the couch as their thighs pressed against each other, both of their impressive manhood’s now over 9 inches long leaking pre while the two kissed previously. The both of them had to be over 6’2 looking massive even compared to himself. “Oh, hey Dave didn’t hear you come in.” Adrian said in a luscious deep voice. “Bro thanks for those shakes they were fucking GOOD!” Michael said licking his lips as he looked at Dave with a hunger in his eyes. More terror filled Dave’s mind as he realized his roommates had opened his delivery and take the shakes for themselves. “Please fucking tell me you dweebs didn’t drink them all.” “Don’t worry were not monsters of course we left you one.” Adrian said. Without a second thought Dave’s body moved on its own scouring for the shake in the kitchen seeing the pack torn open with only one bottle of the four left by itself. He quickly twisted the cap off and chugged it down eager to see the results it would have on his body since his small scrawny twink roommates blew up to monstrous sizes. Adrian and Michael watched in horny anticipation as they were waiting to watch the guy, they’ve been pining for grow into a god. The process was already starting. His stomach bubbling as the shake slid down his throat. His muscles growing fuller at a slow rate as he was painfully aroused his average 6 incher tenting in his shorts as his body started pumping itself larger. But like most of his advances in bed the growth that came finished within seconds his cock exploding in his shorts as Adrian and Michael watched in disbelief. Dave had never been more embarrassed in his life as he felt like he had only added a measly 10 pounds of muscle and not an inch of height to his body as his godly roommates looked at him with disappointment in their eyes. “What the hell did you dweebs do why didn’t I grow like you two?!” “Dunno man we just drankem like you did.” Adrian responded. Michael chipped in “Guess you shouldn’t have been so proud of those genetics after all huh Dave!” Dave was appalled by Michaels observation, it filled him with a sense of humiliation and need to lash out, but as he looked at the much larger man in front of him, there was nothing he could do but accept his fate. Just when he thought things couldn’t get any worse a guttural moan escaped Adrian’s cum ridden mouth. Bracing himself against Michael “OH FU- … IT’S HAPPENING AGAIN!” “oh god….PLEASE NO!” was all Dave could think as every single muscle in Adrian’s body rippled with strength as he grew once again now becoming inhumanely large as he bucked against Michaels body. In all his euphoric torment Adrian was at the mercy of Michaels touch as he pleaded for sweet release. “please bro….help!” was all he could mutter as Michael quickly understood and proceeded to help his friend out Taking his large head into his mouth he put his skills to good use as Adrian quickly blew his load into his mouth as his growth subsided. Michael struggled to chug down the copious amounts of cum being blasted down his throat almost choking as he savored every drop that was being shot into his stomach. Minutes pass as Dave was left mortified, glued to the ground he stood on unable to look away as Aiden had become the very thing, he so desperately craved for himself. As he got control of his body again Adrian pulled Michael off his 13 incher and sat him on his lap his head now over a foot taller than Michaels. He then turned his hear upwards muttering out a thank you before planting a kiss on his lips as thanks for his help. Breaking the kiss, he looks back at Dave seeing the man that was once huge to him looking up at him with awe and jealousy. “Don’t look so glum bro maybe you just didn’t grow enough the first time…well for your sake I hope there is a next time.” Adrian’s words cut into him like a knife destroying his confidence so easily for the first time in his life. He couldn’t even get a word out trying to respond as he watched the two gods enjoying their new bodies together. That’s when Michael chipped in with his own thoughts. “Oh, maybe there’s hope for you yet. Your dad swung by earlier and he took one of the shakes with him before we got into them.” A chill ran down Dave’s spine hearing Michaels words now only thinking one thing. “I’ve got to get home and pray that dad hasn’t drunken that shake.”

Some quick smut I banged out today. Give it a like on my Tumblr if you're so inclined. Inspired by a photo Michael Kidd, shot by Rey Rey's Photography. He is not the character, this is fiction, you're an adult so you know the drill. Please, don't sue me. I'm poor. *** Dad wouldn’t tell me what he was up to but he was bigger. The way he filled his shorts in was obscene. He said he was just working out harder. Right. It had only been a month since mom left him and he’d grown. He been growing. He kept growing. My father got visibly larger every day. We’d worked out together before. Lifting weights was our regular father/son bonding since I was twelve. Even when I came out, we didn’t miss a session. But almost imediately after mom left, he insisted on training alone in the basement. He would’t let me down there anymore. Said it wasn’t me, just that he needed space alone. I figured he was crying down there, needed a place where he didn’t have to be “strong” when he felt weak and helpless. Then I heard the grunting through the vent. At first I thought he had a dog down there. A weird ass dog to boot. Maybe one of those mutts from Ghostbusters. Mom was allergic to dogs but dad had grown up with them. He actually got choked up talking them. He always stopped to pet dogs who came across him when he was out. But I never heard those sounds when he wasn’t down there. He’d have told me if he had a dog. None of those dogs made the sounds I heard. They were borderline sexual. That’s why I had to go down there. I needed to know what he was doing, why he had to be alone instead of spending man-time with his only child. He left the door unlocked one day while he was out. I’d been coming over mre often to check on him. Dad had said some stuff that made me worry he might hurt himself. Break-ups will cause that, especially one after thirty years of marriage. But I was glad he was out. I thought he might have found a girlfriend. And it gave me a chance to snoop. But I wasn't ready for what I found. The muscle mags were one thing. Dad was working out hardcore. Okay. Not that I ever knew he had so many. Then I saw that some of those mags had nudes. I didn't even know they still published skin mags with the Internet going strong. So my dad was gay and didn’t even bother to tell his queer as fuck only son. Terrific. And the mags were scattered everywhere. Pages were lying loose on the floor. Some were stapled to the wood paneled walls. Then there were the rags. Torn up t-shirts. Ripped pants. Jockstraps with the jock torn open. All scattered everywhere. So my dad was turning into the Incredible Hulk in the basement? No wonder mom had left. One of the shirts--a nice polo shirt I’d gotten him for his birthday, I might add--was stuck to the wall like he’d thrown it there. I saw splatter marks from the impact. That splatter? It was cum. Cum was fucking everywhere. Some of it was even fresh, scattered all over the mags and the exercise equipment. Pools of it. The smell was overwhelming. And it made me hard as a rock. I’m not even a smells guy but it turned a switch on in my brain and I couldn’t turn it off. I tried. Something about that stench made me feel manlier, like I was getting bigger and stronger just from inhaling my father's crazy-ass super loads. I took deep snorts of the stench. It made my nose buzz. It didn't even smell like cum or sweat as much as it smelled like manhood. And manhood smelled terrific! It felt terrific! I put my finger into some of the cum that he'd shot on the lifting bench and thought "fuck yeah, dad." I had a vision of him in his more powerful body pushing those weights up and down while he was rock hard and... I snapped back, sickened. I was in my childhood basement, holding my crotch in my hand while I was putting a cum coated finger into my mouth while rock hard, thinking about my own father. I got the hell out and thanked my lucky stars that Dad hadn't come home to catch me. But I was still rocking a stronger hard-on of my life for two hours, even though I tried to think about anything other than sex. Then the call came. “Abel,” dad said, “Let's go for a walk.” His voice was cold. Growly in a way that was unfamiliar. I hesitated but said yes. If he wanted to yell at me, so be it. I had some yelling to do too. When I got to the park he walk looking alpha as fuck. That had become standard but the effect never diminished. On that day, he seemed twice as manly as the day before and I hated it. On any other man that would be instant boner fuel. Thick, vascular thighs. Pumped arms. Gray beard. But he was my dad. Even gay boys don’t get hard to their own dads. I never had before. Then I caught a whiff, just a little whiff, of that freak man-smell, It might have been my imagination. Didn’t mater. I felt my dick buzz all over again. And I felt shame. “I’m not mad, Abel. I wish you hadn’t gone down there but, well...” Dad kept his eyes on me and I was the one who looked away. “That’s fucked up, Dad. That’s really... I don’t wanna know.” Sometimes we tell lies thinking they’re the truth. “You have to know now. I can’t keep it secret much longer anyway.” “Secret? What?” Just because dad wasn’t yelling didn't mean I couldn't. “Is this the shit that drove mom away?” “No. But if she hadn't left, this wouldn't have happened. I'm glad it happened too." “God damnit. Just tell me what's going on so you can get it off--" I winced. Bad word choice "--your chest." And, with even better timing, I noticed Dad's chest flaring. He'd always had a good shape to it but, for the first time, I realized my dad had pecs. Big ones. "Are you gay, Dad? Did you let me come out to you and not tell me you were gay too? Because that’s really fucked up. That’s fucking cruel. That’s...” My voice was breaking. “It’s not quite like that. I mean...” I shouted “Then what the fuck is it?” “Shut up.” If he'd slapped me with the back of his hand, it wouldn't have been as effective. “Follow me.” And I did follow, red faced and sniffling. We followed a paved trail deep into the woods, then he went off on a dirt path. I thought it was for bikes but it was too narrow and unkempt. “It happens at home sometimes. I like that. Gives me a chance to explore it on my own. But it's better here.” I screwed my face up in disgust but, before I could complain, I caught that scent again. “It’s better with the others. It’s stronger. Fuller. I dunno. I need to be with the others.” “There’s a group of you? Aw, dad. You were always warning me about internet freaks and now--” “This ain’t on the internet, Abel. And you better not tell anyone. We can’t let outsiders know.” That was when I noticed Dad's voice. It was deeper. Strained. He huffed and puffed. He put his hands on a tree and stretched out. His back... it was wider. "That smell means it's coming, son. It's coming real strong." I heard footsteps. Leaves rustling. “I’m sorry about this. But you won’t be. It’ll bring us closer together, I promise.” He punded his fist against a tree. I heard something snap. Not a branch from the men walking towards us but from his body. There was another snap. Then Iooked down at his ass. How and when my father had gotten a bubble butt, specifically a perfect bubble butt, was beyond me. And all of the sudden, as he arched his back forward, popped that ass out, cried out, and the cloth split open. I saw my father's ass crack for the first time in my life. And I smelled that superhuman man-funk erupting from his skin, stronger than what he'd left in the basement. And as my dad grunted and groaned and swelled and stretched, I saw those others come out. They were not men. Men aren’t that big. Guys spend whole paychecks on drugs and gym hours to look half as powerful. Now I know it’s a waste. They wore tatters that were wrapped around their carved-stone arms and legs. One man tore the remains of a shirt from his chest. Schwarzenegger could only dream of having a chest that big with a waist that small. I didn’t say no. Didn’t say yes either. I might have flinched or pushed a hand away once. But I walked head first into someone's someone’s hard, hairy, inhuman chest and any resistance I had went at that touch. I sank to the ground, surrounded by a set of Tom of Finland super cocks that all had a variation of my father’s freak smell. Then I found the one that wasn’t a variant. “I have to do this, Abel" he said. He pressed my head against his crotch. "I tried to fight it but I don't want to anymore. I wan’t you to be one of--” The moment he said “us.” I clamped my mouth on his cock and he growled. His voice dropped another octave. “I should have done this sooner!” the others laughed. Then they cheered. They cheered because the saw the start of my body swelling up and stretching out. I moaned because I felt stars exploding inside myself. I roared because I felt like a man. More than a man. More than an animal. When people ask me what's going on, I tell them I'm working out harder. It's true. I haven't bought new clothes yet. I don't want to. I'll do so when I'm down to my last set. Then I'll buy a new wardrobe to destroy. I've moved back in with Dad. It's easier that way. More private. More satisfying. When the urge overwhelms one of us, we both go for the ride. The house is a mess now. We fuck too much. Break too much. The neighbors are complaining. They say there's a smell coming from the house. The women don't like it. But the men? They've been poking around. Trying to see what's going on. Needing to smell what's going on. I think they'll come around soon. They might do it without us. I'm already seeing the changes on their bodies. Less fat. Less bone. More muscle. More men. They're looking alpha as fuck these days, but Dad is the real alpha. I'm second in command. We're sitting back. Watching it happen. Waiting. It won't be long. We can wait. Barely.

In May of 2020, geektofreek posted this short story: A Conversation with My Son I liked the scenario so much that I wanted it to continue. I wrote an extension of the conversation for my own pleasure, squeezed quite a bit of private enjoyment from it - - and then sort of forgot about it until yesterday. With all due respect and credit to geektofreek who hasn't been around any of their previous platforms for a quite a while, I decided to repost the original story followed by my extension. I hope you enjoy it as much as I did. Warning: The son in the story is 19 years old. Although there is no sexual contact between the father and son, their conversation is undeniably sexual. If this is likely to bother you, don't read it. ********************************************* A Conversation with My Son by geektofreek (Part 1, slightly edited) I don’t usually like to talk about these sorts of things. Personal problems and such. But my son, Aidan.... He’s just growing so out of control! You would think at nineteen-years old he would have stopped or slowed down a little. But no, not him. It’s almost as if his growth just keeps increasing. Taller, wider, bigger. This never-ending factory of testosterone! Especially his muscles. 270-pounds now. I’ve honestly never felt so small and inferior around another man before! “M-Maybe it’s time you get a girlfriend or something, Aidan...” I couldn’t help but stutter one night. Right at the dinner table, watching him obsessively flex between bites, so in love with own increasing power, his own muscles. He could barely take his eyes off himself. “Meh...” Aidan, grunted in response after finishing off every bit of meat. *BURRRPPP! “No one’s really caught my attention...” He continued, giving his mammoth muscle arm a couple of pumps. 24-inches of hulking teenage bicep. Seeming not even the slightest bit interested in the conversation. No girls. Not even guys. I honestly wouldn’t have cared if he was gay. But it was always just about his muscles. Nothing more. “Plus, I honestly just want to focus on getting bigger...” Aidan stated like always. Pumping the Everest-sized peak of freaky bicep, right up against his face, staring at it obsessively. “Bigger?” I stuttered, dropping my fork to the floor. And yet the conversation had me completely captivated. With my curiosity at a tipping point. I just had to know... How big did my son want to grow? “Well, like... how much bigger...?” I finally had to ask. Seeing a bit of surprise in his face, the big wheels in his small head slowly began to turn with his face turning a little red. It was almost as if he was embarrassed to admit. “It’s okay, son... we’re all friends here.” I tried to comfort him. But my curiosity wasn’t prepared for the magnitude of my son’s muscle lust. “I don’t know, Dad...” Aidan, finally spoke up. “I’ve honestly been having the craziest dreams...” He continued, already making me gulp, watching him bring down one of his arms, adjusting himself in his seat, pulling and tugging at his skintight bulging gym shorts. “Muscle growth dreams, I guess you could say...” He bit his lip. “Muscle growth dreams?” I questioned. “Yeah, Dad...” Aidan, gulped. “Except sometimes, well... I don’t ever stop growing!” He shockingly continued. “Bigger, and bigger, and BIGGER!” Groaning with this insatiable lust. “J-Jesus, Aidan...” I stuttered in disbelief, especially as I watched his huge nipples begin to harden, adjusting himself so much in his chair it began to creak and crack, almost as if he was getting horned up. “400... 500-POUNDS of muscle!!” Aidan unexpectedly snarled his untamed beastly muscle lust. Suddenly flexing into a most muscular pose, blowing his tank-top apart like paper right at the dinner table. *RIIIIPPPP* “F-FUCK!!” Making me squeal like some schoolgirl, shrink into my chair, suddenly overshadowed by these two monstrous blimps of muscle-breast, pecs bigger than watermelons and twice as hairy as my own. “But you’re already so big, son...” I blubbered in confusion, feeling as if I had opened the biggest can of worms. And yet he wasn’t nearly finished describing his fantasy. “More... and more... AND MORE!” He shamelessly continued. “800-pounds... 900-POUNDS! Urrghhh!” Aidan really groaned, grossly bucking his hips, thumping his huge dick a couple times against the underside of the table. “1000-pounds...” Aidan shuddered, whimpered, as if that was the ultimate number. This big ungodly muscle goal. “Unnghh... I’m so sorry, Dad...” Aidan cringed looking down at his foot-long boner lifting the table off the floor. Trying to stop himself, control himself. I once heard his friends refer to it as “The big pussy crusher.” “I just get so excited...” Aidan admitted, rubbing his gigantic muscle chest, flicking his huge, rock-hard muscle nips even though he was embarrassed. Then again, this wasn’t the first time this had happened. Seeing my son uncontrollably horned up was becoming an increasingly frequent awkward event, usually occurring after a heavy workout, but never so randomly like this. “Look, son...” I tried to be supportive. “That’s quite the huge appetite you’ve got there...” I stated admiringly. With his cock still raging out of control, tilting the table, sliding the dishes slowly towards me. My unsatisfied curiosity drove my ignorance to a whole new playing field. “Is it even possible for someone to grow that big?!” I don’t know why I asked. Obviously it wasn’t possible. And yet, I couldn’t seem to stop myself from feeding into my son’s insane fantasies. “I don’t know if it’s possible, Dad... but I want it SO BAD!” Aidan groaned with unbearable lust, cringing, and gritting his teeth helplessly, with his cock suddenly throbbing, raging, appearing to be a whole inch longer and thicker. I thought he was going to cum! I remembered all those times I had to change his sheets in the past couple of months, all the wet dreams he was having... Were they all about him growing!? “Jeez, son... at that size, you’d be squatting semi-trucks,” I said jokingly... *RIIIPPPPP* “SEMI-TRUCKS!? Unnnghh, DAD!!!” Aidan roared with embarrassment as he finally came uncontrollably. “My LEGS would have to be ENORMOUS!!” He roared with wonder, as if I just exploded his imagination. I watched his gym shorts blow apart with his huge horse-crushing cock emerging, engorging to a whole new level of monstrosity, gushing like a fire hydrant, so much cum I didn’t even think it was possible! Rope after rope of thick, warm semen all over the chair, the table, his feet... his gigantic ape-sized hairy muscle legs. “YOU shouldn’t SAY such things, DAD!!!” Aidan had totally lost it, groaning in total ecstasy from a big rumbling pleasure explosion, tilting his head back helplessly. What a fucking beast! While his eyes were closed in cringing embarrassment, I shamelessly peeked under the table... “Oh god...” I was even more astonished. How was this my own creation? My own flesh and blood? My own son? I had never seen a cock so big in my life... not even in the wildest porn! And he couldn’t stop cumming, leaking so much man-juice all over the floor and his shoes, draining his big bull-sized testicles to the very last drop, like he hadn’t released himself in months, rumbling our tiny house as he helplessly bucked his huge, car-crushing muscle butt. “Dad... please...” Aidan choked up a bit. I knew I must have been caught. “Please don’t look...” he begged me. I didn’t know how to respond. Raising my head, I saw him still panting, with his tongue sticking out, his face surrounded by muscle, suffocated by his pecs, drooling helplessly down his colossal hairy chest. “I swear, I’m not gay!!” Aidan unexpectedly continued. “I just really... REALLY like MUSCLE!” He shuddered a bit more, shooting out one last throat-choking load, all his muscles bulging, tensing. “Jesus, fuck, son...” Was all I could say. “I guess I’d better start buying you more meat, then.” *************************************************** Part 2 - The Conversation with My Son Continues by FallenAway “Jesus, fuck, son...” Was all I could say. “I guess I’d better start buying you more meat, then.” Aidan moaned and looked at me, half surprised and half worried, maybe. “Let’s double your portions. How does that sound?” His chest expanded with a huge breath, and his monstrous cock started tilting the table again. “Dad! What are you saying?” “I’m proud of you, son. I love you. I want to help you follow your dreams. How about triple portions? Is that enough?” “Aww, fuck!” He groaned and arched his back, popping eight bricks of hard abdominal muscle into sharp relief. “Dad! That’s enough!” He exhaled and paused, flexing the huge balls of his biceps again. “For now…” He started to relax. “That’s my boy! No limits, right? Do you need heavier weights? Should I buy some old cars for you to lift?” “JESUS, FUCK!” His body went rigid, and the table finally rose high enough to send all the dishes crashing to the floor. “I’m sorry, Dad! It never got that big before! I didn’t mean to…” “There’s nothing to be sorry about, son! You’re a growing boy. No… you’re a man now. And I’m going to help you become the biggest, strongest, most muscular man who ever lived! How does that sound?” “Unnnngh…” Aidan tensed all his muscles. “Fuck, that sounds great, Dad! I can’t believe you’re not mad at me.” “Mad at you? What for? For being a fucking muscle stud? I couldn’t be prouder! Besides, I wouldn’t dare get mad at you. With all that muscle, you could probably pick me up with one hand and throw me through that wall!” “GOD, DAMMIT!! Don’t SAY that Dad!!” He grimaced. “I mean… I’ve thought about that… and you’re right, I could. But fuck! I don’t want to do that!” “I know, son. I’m just saying, I know you could. It’s obvious. But you won’t need to do that, because I will be happy to do anything you want that will keep you growing and help you to look even better than you do right now. You’re a beautiful young man, Aidan.” He was rubbing his thick chest again. “Really? You think I look good like this, Pop?” “Hell, yeah, son! You know I’m not gay, but any man who looks at you must be wishing he looked like that. I could never dream of looking as good as you, and that’s why I’m so amazed and proud to have such strong, handsome son. Like I said, anything I can do to help…” “Well… I’m gonna need bigger clothes…” “Obviously! We’ll have to get things that stretch a lot, and they’ll show off your muscles better.” “Cool. And… this is kind of weird, so you can say no if you want, but…” He stood up and put one of his big hands over his much bigger dick out of modesty. “Could you help me trim my body hair? It’s coming in so thick I can’t keep up with it, you know?” “I can see that.” His body was stunning. So huge and tall and… so powerful! It was hard to believe he was only 19. “I don’t want to shave, though. I want to look like a real man, so if we could just keep it short and sexy, less like a gorilla, you know?” “I know exactly what you mean, I agree. A man should have some body hair, in moderation. We might have to trim it every couple of days, son. And that’s fine with me.” “Thanks, but honestly it needs to be done every day. You wouldn’t believe how fast it grows. My butt crack looks like a forest, and I can’t reach back there… Sorry, Dad! That’s gross. I don’t expect you to do…” “It’s fine Aidan, really. Don’t forget, I used to put diapers on that butt! Although it wasn’t as big and hard as it is now. It looks like a couple of boulders!” “Fuck yeah!” He turned sideways and flexed so his ass looked higher and rounder. “That’s from all the squats. The girls love my ass. They can’t keep their hands off it.” He smirked. “Jeez, Dad, I can’t believe you’re being so cool about this. I really appreciate it.” “Not a problem, I want you to be happy. Um, can I suggest something?” “Sure, Dad. Of course.” He did a side flex and admired his thick biceps and triceps. “Well, I think you’ve been spending so much time in the gym that you never get out in the sun. No offense, but you’re rather pale. Don’t you think you would look better with a good tan? When you were younger you used to get as brown as a chestnut in the summer when you spent more time around our pool.” Aidan smiled as he looked down at his bumpy abs and his tree-trunk quads. He blushed a little. “You’re not the first one to say that. I’ve been so focused on getting bigger I wasn’t paying attention. I guess that would look hot, especially after you trim all this hair.” “You’re gonna look like a fucking god, son. I mean, you already do, but you’ll be a golden god.” He smirked again. “The thing I hate though, Pop, is trying to get tanning oil all over my body.” He turned his back to me. (He was right, his butt crack did look like a dark forest.) “That’s a lot of area to cover.” He flexed his back and spread his lats. Muscle rippled everywhere. “I can’t reach my back now that my arms are so fucking huge.” He raised his arms into a double biceps pose. I could feel the heat coming off his body and felt a little lightheaded. “You see the problem, Dad?” He looked back at me with a sparkle in his eyes. “Um… that’s not a problem, son. That’s a goddamned wonder of the world! How did you get so big?” He turned around to face me again, squeezing his big, soft dick. “Lots of lifting, and a hell of a lot of food. You know that. You buy the groceries.” It was true. I had been spending a lot more on food lately, and it was just the two of us in the house since his mother died years ago. I know I wasn’t eating more than usual. Maybe less, in fact. Aidan took a step closer to me. “So, what do you say, Pop? Do you think you can help me get that tanning oil all over my huge body? Or would that be too weird?” “Weird? No, why would it be weird? You need help, and I’m here to help.” “Uh huh. You keep saying that. I know you want me to take good care of this.” He ran his hand up and down one side of his torso, feeling his smooth teenaged skin. “So, I’m thinking, since you work from home now, you can start the day by cooking us a nice big breakfast like you do on Sundays, except every day. A dozen eggs, bacon, oatmeal. You don’t have to eat it if you don’t want to, but I need a big breakfast, okay.” He stroked his abs. “Okay. That makes sense.” His skin was so smooth and tight against his muscles. I really did want him to take care of it. “Then I can use that fuel for my first workout of the day in the basement. You can get something done for a while. Unless you want to watch me lift. Maybe you would like that.” He flexed one massive bicep again and looked at it, then at me. “Maybe. I would be curious… If it’s okay with you.” “Hell yeah, I like an audience. It helps me grow.” He smiled that crooked smile again. So fucking handsome! He continued, “While I'm lifting you can towel me off between sets because I sweat a lot. That’s why I drink gallons of water every day.” It was amazing to see how much he could swallow in one go, with his big Adams apple bobbing up and down on his thick neck. “You’ll want to rub me nice and dry so it will be easier to trim all this fucking hair.” He widened his stance and let his dick and balls dangle while he ran both hands over the silky black hair on his muscular thighs and calves. He dragged his hand up his furry abs and chest. I was thinking carefully about how much hair to leave on each part of his body to enhance his gorgeous muscles. I wondered how I would handle his bush and his balls. He snapped his fingers. “Are you still with me, Pops?” I startled a bit. “Yes, of course, son. I was just… planning.” “Alright, I’ll need a big protein shake after each workout, so make sure you have those ready to feed my muscles. They get really fucking hungry after I lift!” He flexed both arms again and growled. “I’m sure they do, son. I’m sure they do. I’ll have what you need. Don’t worry.” “Great. I’ll drink my shake while you start trimming the body hair. Make sure you get a top-quality trimmer. I don’t want any snags from some cheap, dull blade, okay?” He gave me a look to make sure I knew he was serious. “I’ll get the best, Aidan. Only the best for you and your body. Trust me.” “I trust you, Dad.” He reached out and squeezed my bony shoulder. It was the first time he had touched me in a long time. It felt nice. “After the trimming, I’ll need a shower.” “Of course.” I waited for him to go on, but he didn’t. “Would you want…? I mean, would you need…?” I couldn’t say what I was thinking. I felt my face flush. His smiled a little and reassured me. “I would never ask you to do anything that would make you uncomfortable.” I felt… relieved? “But… if you want to… I mean, it would be fine with me if you wanted to join me. Then you wouldn’t have to shower earlier. It would save you some time, and it would really help me if you could make sure I get all that hair rinsed off. And I can’t wash my own fucking back anymore, because, well, you see how big I am. And I’ll be getting bigger…” My heart was thumping, thinking about my son getting bigger. “You don’t want me to get acne on my back, do you, Dad? How would that look?” “Terrible. It would look terrible son. Your beautiful skin…” “I know, I need to keep it that way. And guys shower together all the time at the gym. ‘No homo,’ as they say, right Pops?” He grinned. “I trust you, Dad. Even though I’m fucking irresistible!” He threw another pose and laughed. “I’m just kidding! We understand each other, don’t we?” He playfully shoved a huge fist against my shoulder. I understood. I really did. “Of course, son. I would be honored to shower with you if it will help. I only hope it doesn’t bother you to look at my old body. I’m just an ordinary human, unlike you.” “Heh! I like that, thanks! It won’t bother me. Matter of fact, I like to compare my muscle bod to smaller guys. It makes me feel so much bigger and better. Because I am. It’s just a fact.” “It is, you’re right. No point in being modest about it. You’re the finest specimen of a man I’ve ever seen.” “Thanks, Dad. I’m so glad we can talk about this now. I thought you were going to try to talk me out of growing as big as I want to. And I never thought I’d be standing here all fucking naked with you in the dining room. This is so cool.” “It’s a new experience for both of us, son. It does feel good.” I couldn’t stop scanning his body. How could that be made from the same genetic material as mine? He looked like a different species. “So after our shower, you’ll want to get that tanning oil on me right away. It would be good to lock the moisture in while I’m still wet. We might as well do that out by the pool. I can spread out on one of the lounge chairs while you put a nice shine on these muscles. Now that I think about it, you need to get a bigger, sturdier lounge chair. I’m so fucking tall and massive now, I don’t think the ones we have will hold me anymore. Even at my current weight, I’ll just crush them. Look for a metal one, and make sure it has a 500 lb. weight limit. That should do it… for now.” My heart fluttered. I felt like I should be writing all this down, but I knew all the details would be burned in my memory. “What kind of tanning oil do you want?” “Good question. Just get the most expensive kind. You don’t want to take any risks with this.” He gestured to his magnificent physique. “Buy it by the case. Like I said, there’s a lot of area to cover, and you’re going to want to rub it in thoroughly. And I’ll be naked, by the way. I don’t want any tan lines, and a ‘golden god’ should have a golden dick to match, right?” Aidan grinned. “I can’t believe you called me that, Dad. That’s a real boost to my self-esteem. Not that I’m lacking in that department.” He made a smug, goofy face. I couldn’t help but wonder how he would get an even tan on that monstrous cock. I had to ask. “Um, to get that… golden dick, as you called it… wouldn’t you have to make sure it stayed… full size… so all the skin would get tanned?” “Heh! I’m glad I have you here to think about things like that, but I don’t think that’ll be a problem. I can stay hard for as long as I want. You’ll see. It’s a top-quality tool that does whatever I ask it to do.” He squeezed his fat prick for emphasis, and continued mapping out his, and my, daily schedule. “I figure I’ll need about an hour in the sun – that’s a half hour each for front and back in the middle of the day – that should get me nice and brown in no time.” “Yes, your skin always tanned so beautifully. I don’t think you ever got a sunburn.” “I’m sure you’ll keep an eye on me while I bake to make sure I don’t get overdone. Especially the delicate parts.” He winked. “You can do that while you’re making lunch. I’ll need a fuck-ton of lean protein every day, brown rice, lots of vegetables, milk, eggs, yogurt. That’s the ideal, but I can eat pretty much whatever I want, and it still turns to muscle.” He flexed a fat bicep again and admired its shape. “Did I ever tell you about the time I ate twelve whole pizzas at Giovanni’s?” “I don’t think so. I’m sure I would have remembered that son. I’ve always admired your appetite.” “Yeah, one of the guys at the gym challenged me to eat six pizzas in one sitting. I think he was trying to sabotage my routine. But I said, "Fuck that! I’ll eat twelve!" And I made him sit there and watch me do it. He barfed just from thinking about it, but I felt fine. In fact, I had a milk shake for dessert.” He flexed his abs and pulled at the thin skin that wrapped around each block of muscle. “I’m still ripped as fuck, as you can see.” He smiled that cocky smile that oozed superiority. “Then I picked the guy up and carried him into the restroom. I shoved him into a stall, whipped out my dick, and blew a huge load all over him. I just splattered him until he was soaked! God, it felt good. He deserved it. Then I went back to the gym for another long workout, and I lifted heavier than ever. That dude never came back to the gym. Probably gave up weightlifting. He knew he couldn’t compete with this.” Adrien did a beautiful full body flex and admired himself. Hmm. That was a side of my son I hadn’t known about. But it didn’t worry me. “Now that I think of it,” I said, “I do remember a large charge from Giovanni’s on my credit card. I thought you bought pizza for all your friends that day.” “Fuck no. That was all me.” He patted his hard, cobbled gut with a self-satisfied smirk. “Anyway, after lunch, I’ll go to the gym for my heavy workout, and you can get your stuff done. That’ll take about three hours. When I come home, I’ll need my protein shake, and then I’ll take another shower.” “Okay. Will you want me to…” “No, Pop. I’ll want some privacy. I get really horned up after those workouts and I need to pump out a few fat loads just to calm down. Honestly, it wouldn’t be safe for you to be in there. You saw what happened at the dinner table. I don’t have a lot of control when I start fantasizing about getting bigger and stronger, massive as fuck...” He groaned and grabbed his dick again, squeezing it hard to keep it from inflating. His forearm bulged with the effort. “I understand son. That’s perfectly normal for a young man. Nothing to be ashamed of.” “I’m not ashamed of it at all. I love what my dick can do. But I’m not sure I would call it normal. In high school the guys used to call me ‘the geyser.’ None of them could blow as much or as hard as I did. And it’s even better now.” “I must say, I was astonished by your… productivity earlier. I had no idea a man could… make so much…” Aidan blushed and smirked. “That was so fucking embarrassing, Dad. But you handled it well. I still can’t believe you’re not upset. I mean, look at that puddle on the floor! And all those broken dishes. I never lifted a table with my dick before, but… damn that’s fucking hot now that I’m thinking about it.” “It was… impressive, son. I’m not gonna lie.” “Do you want me to clean that up?” “No, no! I’ll take care of it. Do you want to finish going over our schedule?” “Uh, I think you’ve got the general idea. I eat, lift, get groomed, catch some rays, eat again, lift like a fucking mad man, come home, and empty my balls in the shower…” “Then you’ll want dinner. And, as I said, I’m going to feed you triple the amount of meat you’ve been getting. I want to see you really pack on some beef. It’s time to take this seriously.” “Uh… yeah. I mean, I thought I was, but I guess I could step things up.” “If you want to reach those goals, you’d better.” “Okay. Thanks, Dad. Um… do you think those goals are realistic? I was just telling you about my dreams…” “Dreams can come true son! And I’m here to help you make that happen.” “So, when I said I would keep growing, and growing, to…” “400... 500 lbs. of muscle, to start. Yes, I was listening.” “FUCK!” He grabbed his huge dick as it expanded. He sucked a huge breath into his massive chest. “Dad, maybe we shouldn’t get carried away…” “Why not? You must dream big to get big, son! Why not 800… 900 lbs. of hard, powerful muscle?” “JESUS, FUCK! Dad, it’s going to happen again!!” His muscles started to swell as if they were being pumped up. His cock lengthened and hardened into a massive, shiny club. His whole body flexed, and he groaned loudly. I could tell it felt good, but he was trying to hold back. “Aidan, it’s okay! Let yourself enjoy it! You deserve everything you’ve worked for.” He started stroking his cock, now slick with precum. “I want to see how far you can take this. I want to see what you look like at 1000 lbs. Make me proud, young man!” “OH, GOD! DAD! IT FEELS SO FUCKING GOOD!” He let go of his cock and watched it stretch just a little bit longer and a little bit thicker. The head was huge and purple and constantly oozing. His giant balls plumped up and pulled his sack taut. My son flexed his enormous biceps and looked at me with an expression I couldn’t quite read. It was cocky, for sure. He was grateful, I think. But there was something else… He growled and stepped closer, towering over me. Flexing his hard, hairy pecs. He reached out and grabbed a handful of my shirt with one hand and effortlessly hoisted me into the air. “Fuck, yeah, Pops!” He flexed his other arm as hard as he could and pulled my face close to his. “I could throw you right through that fucking wall!” I looked into his eyes and said, “I know, son. Of course, you could.” He smiled a little. “But you know I won’t.” “That’s right. But I like knowing that you could.” “FUCK!” He moaned, and his cock spit out more precum. “Why does that bone me so much?” “Because you know I want this as much as you do.” “Uuuugh! Yes!” He lifted me higher and arched his back. Veins popped out on his abs, visible through the silky black hair. “I fucking knew you would help me! I don’t know how, but I fucking knew it! Maybe it was in one of those dreams…” “Maybe. Does it matter?” “Are you sure you’re on board with this? Are you willing to do everything I asked you to do?” “Hell yes, Aidan! I can’t wait to get started. This is gonna be great! I can’t wait to see you squat a semi-truck.” “OH, FUUUCK!! YOU’RE THE BEST DAD EVER!” He shook me in his fist like a rag doll. “I’m gonna hug the shit out of you! I hope I don’t break you!” He lifted me over his pulsating monster of a cock and pressed me against his hot chest and abs, wrapping his massive arms around me as gently as he could for someone so strong. It felt amazing. “I’M SORRY, DAD, BUT I’M GONNA MAKE A HUGE FUCKING MESS! I CAN’T CONTROL IT ANYMORE!” I patted a slab of muscle on his side. “That’s okay, son. Let it go! Enjoy it!” “UUUUUUUGH!!” He groaned in ecstasy and let loose probably the biggest load of cum he ever produced. I heard it splattering against the far wall and the ceiling. Jet after jet after jet, as if he hadn’t just pumped out a huge load under the dining room table. I patted his thick, hot muscle again. “That’s my boy! You did great. I’m so proud of you!” The End

Previous chapters: Chapter 1 Chapter 2 Chapter 3 Chapter 4 Chapter 5 Chapter 6 Chapter 7 Chapter 8 Chapter 9 Chapter 10 Chapter 11 Chapter 12 Chapter 13 Chapter 14 In the final chapter of the series, Austin lets Jon take control and do whatever the big muscle bullpup wants to his smaller stepson. Jon is all too eager to exert his full strength and size to get what he wants. Thanks to everyone who has been along for the ride, and sorry for the long delay in posting this last chapter. I guess in some ways I didn't want this story to end, and it didn't feel like it would if I didn't post the last chapter! Even though this story has generated less traction than some of my older stories, I'm really proud of it and I think it's some of my best work. When Austin was finished, he pulled out, leaving behind a streak of cum dripping out of Jon’s huge furry hole. He stepped back and gave Jon’s rump a firm, satisfied smack, causing the big man to gasp and chuckle as he looked back at his diminutive Sir. “That’s my bull, mmm felt so good, pup,” Austin said as Jon turned around, still on his knees, still taller than Austin. Jon raised his hands up to his chest and put his fists together, muscles bulging and tensing as he did, and he cocked his head to one side, seeking his master’s praise. “Arrooooo?” he grunted. His jock-bound cock pressed against the side of the deck, leaking pre, hard as a rock. “Oooh yeah pup, we need to drain those big balls of yours too,” Austin said, stepping closer. He reached his hands out and rubbed Jon’s huge pecs in wide circles, spreading the rain and sweat over the chest hair, flicking across his sensitive nipples. Jon gasped and grunted as Austin teased him. “I want to try something that we haven’t done yet, pup,” Austin said conspiratorially. He reached up and tugged his thick chain necklace to make him look down. They locked eyes, Austin’s green staring into Jon’s intense blue. “Borrrk?” Jon grunted, still fully in pup mode. He was locked in to pup space until his monster cock was relieved of its payload. “Bull, you’re the biggest, strongest, most powerful man to ever exist,” Austin said. He reached over and rubbed Jon’s massive right delt and bicep, marveling at the hard, round, full, fur-covered muscle in his hand. Jon flexed in response, always wanting to impress his master. “And you do such a good job of doing everything I say and having me be in total control all the time, like a good bullpup should,” Austin continued. His hand continued down to the convex curve of Jon’s huge muscle gut. Jon breathed a deep sigh, his belly swelling out even more. “Well,” Austin said, stepping closer and lowered his voice to a whisper. “This time, I want my bull to do whatever he wants to his Sir.” Jon took a big breath and stiffened his shoulders, raising himself up higher and tensing. His cock bulged and burbled out more pre. “I’m going to let you borrow control and use me however you want, pup,” Austin continued, leaning his head against Jon’s huge chest. Jon’s breathing intensified and a shiver of excitement and anticipation ran through him like an electric current. His cock bulged and surged more until the head of it pushed out of the tight jock and rubbed against the bottom of his huge gut. “I will always be in control and expect obedience, but I want to feel the full power of my bull pup when he lets go and does whatever he wants. No stopping until you cum, no matter what I say, no matter how hard I might beg you to stop, you hear that, pup?” Austin said firmly, commanding his pup. “AAARRROOOOOOOF!” Jon boomed in excitement. He bolted to his feet and towered over the smaller man. Jon took in the full power difference he had over his Sir, his mind clearing in a way he hadn’t felt in months, and realized just how helpless Austin was before him. He looked down at the sheer size of himself, his enormous, powerful muscles, his round, furry gut, his stupendous height, and he tensed his massive fists. He’d never felt so powerful in his entire life, had never fully realized just how huge he had become. “I’m all yours, pup. What do you want to do to your Sir?” Austin said, spreading his arms wide, his naked muscular body glistening in the light rain, his cock still dripping with football jock cum. He was so grateful that his master was letting him experience the full power he possessed, the true size difference between them. He felt light-headed at the possibilities. Jon looked down at Austin. Jon was twice his height. Jon was several times his weight. Jon was the strongest man on earth. A grin spread across Jon’s face under his pup hood and couldn’t help but laugh in anticipation and excitement. Jon tore at the jock containing his mighty bulge until the elastic snapped, freeing his manhood. It slapped against the bottom of his gut, 20 inches long and as thick as a milk jug. He growled and breathed heavily, his cock throbbing and leaking pre as he looked down at Austin. He reached down and lifted Austin up effortlessly, scooping him up under the armpits and bringing him up to his pup mask. “AAARRRFFF, WOOOOOF!” Jon grunted as he rubbed his master against the snout of his hood and licked him, tasting master’s cum and sweaty and rain-soaked naked body. Jon’s hot, protein shake-smelling breath washed over Austin and the smaller man groaned. “Yeah pup, use your master however you want, don’t stop until you cum, pup,” Austin breathed as Jon nuzzled him aggressively. “MMMLLAAHHH,” Jon breathed as he thrust his tongue aggressively against Austin’s mouth, making out hard, holding him up in the air easily, his hands rubbing against Austin’s tight, hard, muscular body. Austin could hardly breathe as Jon’s tongue pressed into his mouth, pinning down his own tongue, exploring his mouth. Jon walked to the middle of the backyard as he continued kissing his master, scraping his beard against Austin’s face, overwhelming Austin’s senses. Even Jon’s beard was bigger, thicker, and stronger than he was. Eventually, Jon separated from Austin and held him at arm’s length, looking him up and down, rain and sweat dripping down his naked torso. Jon’s cock throbbed in anticipation. Whatever he wanted? As hard as he wanted? Jon bounced Austin up and down in his hands, marveling at the lightness of his muscular, football jock master. Jon laughed at the absurd power difference he felt, really understanding it for the first time. Jon dropped to his knees and set Austin on the grass. Jon raised his arms up and flexed, huge biceps bulging, his furry pits exposed and ripe. “RRPHHH, MMPH!” Jon grunted and gestured for Austin to rub his flexing muscles. Austin got the hint and stepped forward, running his hands over Jon’s huge arms. “Yeah pup, you’re so big and muscular, huh?” Austin said, worshipping his muscle pup. “You like all this attention, don’t you?” “WRRROOOOF!” Jon boomed and flexed harder. He dropped his left arm and reached around behind Austin before pushing him hard towards Jon. Austin stumbled and fell against Jon’s thick, furry chest, gripping on to Jon’s harness. “Yeah, you like having your chest rubbed, huh?” Austin said, his hands running in circles around Jon’s big pecs and flicking his meaty nipples. Austin’s cock rubbed against Jon’s round, hard, furry gut. “MMM-MMOOOOORE!” Jon rumbled as he pushed Austin closer, crushing the smaller man against his huge chest. He pushed and rubbed Austin’s face against his rough chest fur, manhandling Austin as he ran him over the mountains of his pecs, laughing at the ease he controlled Austin’s body. Austin groaned and tried to speak, but his mouth was full of Jon’s beard and chest fur. Jon adjusted his grip and pushed Austin over to his dense, hairy armpit. “TASTE MY MUSK, SIR,” Jon bellowed as he pressed Austin into his pit. He held him there forcefully, ignoring Austin’s squirming attempts to back up. “BREATHE DEEP, SIR, LET THAT BULL MUSK TAKE OVER,” Jon said. Austin finally gasped and breathed in deep, his mind feeling cloudy and overwhelmed by the force of Jon’s potent, masculine pit musk. “THAT’S RIGHT, SIR. GIVE IN TO YOUR PUP,” Jon boomed. “JUST MY MUSK IS STRONGER THAN YOU…IMAGINE WHAT MY MASSIVE MUSCLES ARE ABOUT TO DO TO YOU,” Jon said with a chuckle before finally letting Austin back up and take a breath. Austin coughed and sputtered and gasped, but didn’t have long to recover. Jon dropped down on all fours, his fists slamming into the ground next to Austin. “RUUUFFFF! GRRRUFF, MMPH!” Jon grunted in pup-speak, the ground shaking, 3000lbs of muscle bear looming in front of his Sir. “GRRRRFFF, ARRRRRF!” Jon rumbled as he surged forward and bumped his huge chest against Austin, who staggered backwards. “Heh, yeah pup, you wanna play now?” Austin said, teasingly, moving backwards and sideways to try to avoid Jon’s massive paws and looming muscles. “You wanna roughhouse with your Sir?” “MMMPH, UUURRRFF!” Jon grunted as he his cock pressed against his furry gut and smeared pre around until it dripped to the muddy grass. He moved forward until his chest and gut were over Austin, then he dropped down, pinning his little Sir before he could escape. “Fuck, pup, you’re so, uugghh, heavy!” Austin groaned underneath his massive pup, pushing his arms up to try to keep his chest off the ground so he could breathe. It was a futile effort; Jon kept pressing down harder with his body weight until Austin was crushed against the dirt, mud smearing on his back. “Can’t… move!” he grunted, and he felt the pain of Jon’s bulk crushing him into the ground. “MMMMPH, MORE!!” Jon grunted as he squashed his little Sir. He could feel Austin wriggling and writhing underneath him, trying to escape. Jon knew he couldn’t. He was too big. And master was too small. He pressed down harder and wiggled his huge meaty ass in the air, reveling in the effortless power he wielded. “HAHAHA, CAN’T ESCAPE, HUH? I’M SO… BIG!” Jon laughed as he scooted his torso forward. He planted two massive fists into the grass, strong calloused fingers digging into the soil easily, then pushed himself up off the ground. He hovered his torso over Austin, then scooted forward. Jon coughed as he shifted around, trying to stand up until a massive battering ram of a cock slammed into his chest. He was knocked over again, a smear of warm pre slicking up his chest. He looked up to see the giant cock looming over him; it stretched from Austin’s belly button to his chin, and it throbbed almost as if it had a mind of its own as he looked at it. “MMMPH, SIR IS SO SMALL!” Jon bellowed as he stretched forward and pressed his elbows into the ground. “AND PUP IS SO BIG!” Jon’s cock suddenly surged forward, pinning Austin onto the ground. Austin fell over onto his back, knocked down by the throbbing, hot cock that pressed down on his torso. It bucked and throbbed as Jon pressed more of his tonnage down, pressing into Jon harder until he was unable to move. Austin wrapped his arms around the cock to try to control it, but it was no use. “Pup, whoa ther—oomph!” Austin grunted but was interrupted by Jon’s aggressive humping, the head of the huge cock punching him in the chin, Austin’s jaw reeling from the impact. “HEH, MMPH, UNNNGGG,” Jon grunted as waves of pleasure shimmered up his spine as he felt his cock press and rub against the furry torso of his tiny master. “EVEN MY COCK IS STRONGER THAN YOU NOW, SIR!” Jon’s huge hairy balls slammed against Austin’s own hard cock again and again as he humped, causing Austin to get turned on again despite cumming just minutes ago. Jon’s cock smeared pre across Austin’s slick torso until the whole thing was coated in pup slime. “AARRROOOOF, GGRRRRRRPH, MMMMPH, BIG!” Jon grunted mindlessly, his thoughts lost in pup space, thinking only about his own pleasure for once. He rubbed and rubbed his massive cock against Austin’s lean, hard, muscular body, harder and faster, pressing the smaller man into the dirt again and again, lost in pleasure. Eventually, he shifted down and re-positioned his massive cock until he felt Austin’s tight, furry hole. His Sir’s hole. “MMMMMPH YEEEEAAAAAAHHH,” Jon breathed as he pushed and humped against Austin’s ass, the massive head pressing hard against Austin’s hole, knocking on the door, insistent, undeniable. The huge head split Austin’s hole apart and started pushing in, a moment of pain rippling through Austin before the cock slipped out and rubbed between Austin’s legs instead. “Pup!” Austin gasped, his back and ass grinding roughly against the grass and mud underneath, rainwater and sweat pooling beneath him as Jon started to rub a furrow into the yard. He looked up and back at the massive, jiggling, harness-bound pecs above him and tried to wriggle out from under Jon. “MMMPH GOTTA MAKE IT FIT!” Jon bellowed. He lined up his huge cock against the warm, tight slit underneath him and pushed harder, thrusting forward aggressively. “Aaaahhhh, pup wait!” Austin groaned as the massive cock head battered him, pushing up against his hole and trying to break in, but only succeeding in pushing Austin’s whole body around. Austin tumbled roughly against the ground, grass and dirt scraping against his back and shoulders. “FUCK, TOO, MMMPH, BIG FOR SIR’S HOLE!” Jon groaned as he pressed harder than ever and pinned Austin with his huge, furry gut, trying to hold him in place. Austin braced himself against the ridges of Jon’s roid belly and felt his hole splitting open, and he groaned in pain. But even lined up perfectly, it wouldn’t squeeze in. “HA, GRRRPH, TOO BIG! HAHAHA!” Jon laughed as he slipped his cock out from Austin’s furry crack and repositioned himself until his cock hovered over Austin’s torso. Jon slammed back down on Austin with all his weight and power. The big bull sighed and grunted and groaned as he resumed frotting on his minuscule master. “Pup, stop, you have to, mmmph, wait!” Austin pleaded, his eyes suddenly bulging with fear. He had underestimated just how massive and powerful his pup was. He patted his hand against Jon’s tremendous, furry flanks trying to get the big man’s attention, but Jon ignored him at first. Austin slapped harder, smacking the muscular lats of the huge man humping into the ground. “Stop, pup, you’re too heavy!” Jon froze in place as his master tapped him, instinctively listening to Austin. Rain fell steadily on his wide back as he panted and huffed, looming over his smaller sir as he lifted his tonnage off Austin’s smaller body. But then Jon remembered. His master had ordered him to use him however Jon wanted, as hard as he wanted, until Jon came, no matter what master had said, no matter how hard he begged to stop. Austin’s exact words rang in his mind. He tilted his head to one side and his tongue lolled out of his mouth, and he looked down at his smaller sir hungrily. “NO, SIR!” Jon boomed. He positioned himself carefully over again Austin and then slammed his full body weight back down on him, pinning him effortlessly. “BIG BULLPUP’S GOTTA CUM!” Jon grunted, his mind obeying his Sir’s original orders to the T. He started humping harder and faster than before. He pressed his gut down heavier against Austin, and a new wave of pleasure washed over him. The furry gut pressed down on Austin’s head and face, pinning him back and down even harder. He readjusted, digging his massive hands deeper into the dirt, scraping up more of the lawn as he braced himself to pound his master harder and faster. “No, pup, this is, pppfftt, too much, I can’t breathe!” Austin sputtered, his mouth slimed by spurts of pre that got more and more viscous as Jon humped and pumped harder. He felt the mud around him rising up and onto his pecs and shoulders as his giant pup rutted deeper into the grass. Austin could feel Jon’s balls growing tighter and firmer as he approached climax. Pup ignored his master, lost in pleasure. “MMMMMPH, RRUUFFFFFF, MORE, BIGGER!” Jon groaned and muttered, his heavy chain lock jingling against his harness, his beard draping down to the grass. Thick, meaty muscles jiggled and shook and flexed as he humped his master recklessly, mindlessly. He looked down and under himself, watching Austin wriggle and writhe against his enormous cock, and he laughed, truly seeing the size difference between them now, his vision blurred in a red haze of lust. Jon had become truly gigantic, but all he could think about was MORE. “OHHHHH, MMMPH, HHAAAHHH,” Jon breathed as he imagined himself swelling bigger still, feeling pride as he knew his master would approve, determined to grow and grow endlessly for him. His cock bucked and swelled, burying his Sir harder into the mud. “HHAAAAARRRRRROOOOOOOOF!” Jon bellowed as his cock exploded, jets of hot white cum spraying against Austin’s face until he was in a puddle of mud and cum, more and more fluid filling up the furrow Jon had dug with his enormous cock. When he was done, pup collapsed down, squashing Austin under him. He felt his little Sir squirm and twitch underneath him. Jon reveled in his superior power and strength. He groaned and sighed as his cock throbbed one final time. Snapping out of his trance, Jon pushed himself up then kneeled upright and let Austin stand. Austin sputtered and coughed and caught his breath as Jon looked down at him, his blue eyes glittering through the slits of the pup hood. “Sorry I got a little carried away, Master, but I needed to cum sooooo bad!” Jon boomed as he sat back on his ass, shaking the ground. “No no pup, *cough*, you were perfect and I might’ve bit off more than I can chew, but you obeyed, *pfft*, Sir’s orders to the letter!” Austin said as he wiped goop off of his torso and face. “Sir is so proud of you, big bullpup!” Jon grinned uncontrollably and reached up to take his pup hood off, revealing more of his masculine face and perfectly trimmed beard. “You mean it, Sir?” he asked sheepishly, a lump welling up in his throat. “Of course, dad, you’re the best pup a master could ever ask for!” Austin said as he reached his arms up, indicating he wanted to be lifted up. Jon obliged and he lifted Austin up. Austin straddled Jon’s torso as best he could and rested his knees against Jon’s chest and his feet against Jon’s gut as he leaned in for an enormous, sloppy, slimy kiss. Their tongues wrestled, Jon’s bigger and thicker but giving way to Austin’s aggressive thrusts. Jon leaned back, supporting his Sir with his enormous hands, and he laid back onto the grass, rain falling softly on them, washing away the sweat and cum that coated them both. “I love you, Sir,” Jon rumbled. “I love you too, pup,” Austin said right back. Both of their cocks swelled back to life as they kissed, harder and harder, Jon’s growing until it pressed against Austin’s perky hole, Austin’s cock smaller but harder and rubbing against his bullpup’s enormous, furry chest. They both laughed and groaned as the rain started falling harder, both of them feeling utter contentment.

Previous chapters: Chapter 1 Chapter 2 Chapter 3 Chapter 4 Chapter 5 Chapter 6 Chapter 7 Chapter 8 Chapter 9 Chapter 10 Chapter 11 Chapter 12 Chapter 13 Chapter 14 — Graduation Fuck Austin pulled into the driveway of their house, the truck laboring as he shifted into park. It wasn’t meant to haul around this heavy of a load in the bed; the handling and acceleration was awful the whole drive home, and he could smell burning rubber whenever he hit the brakes. They would need to upgrade the truck to something bigger soon to keep up with Jon’s growth. Austin came around to the tailgate and opened it. A slimy layer of precum dripped out of the truck bed and onto the driveway as he did, and Austin looked up to see Jon sheepishly scratching the back of his head, exposing his enormous furry armpit and flexing his titanic bicep. His jock was soaked with pre and a steady stream of it leaked out of his cock head. “Oh pup, you’re just raring to go, huh?” Austin teased as he gestured for his big daddy to get out of the truck. “All that vibration from driving got you even more worked up, I bet,” he said. “Grrrmmmpphhhh, ruuarrrfff!” Jon whined as he shifted off of the truck and onto the ground. He rose to his full height, towering over Austin, literally twice his height and over twelve times his weight. Jon reached up and adjusted his harness, the leather creaking and metal studs and rings jingling against his neck chain and padlock. “Come around to the backyard,” Austin said as he led his bullpup around the house. Jon didn’t fit inside the house anymore, not comfortably anyway. Austin had started the process of finding a new property to move into, ideally one with a large warehouse or hangar or barn that could be converted into a living quarters for the growing brute. Jon’s growth had only accelerated over the last few weeks and showed no signs of stopping anytime soon; Austin had to plan for BIG things in the future! Suddenly from behind, Austin was grabbed and lifted up and spun around. “Mmrrowwff, mmphhh!!” Jon grunted as he nuzzled his pup mask against Austin, rubbing his Sir. He lowered him down and started rubbing Austin again his sweaty, furry chest and gut, then lower still until Austin could feel Jon’s slimy cock pressing insistently against his pants. “Whoa there, pup, so eager to please your Sir, aren’t you?” Austin said calmly. He was used to his pup getting boisterous sometimes when he was excited and knew how to handle him. “Well first we need to do another weigh-in. Put me down and hop on the scale, bull,” Austin commanded. “AARROOOF!” Jon boomed, still locked into pup-speak. When he was in pup space like this, he was only capable of simple thoughts and ideas and speech, but that’s how his master liked it. Jon set Austin down and then waddled over to the scale. They had set it on the concrete pad next to the deck after Jon had partially destroyed the deck a few weeks ago. The scale creaked and groaned as Jon stepped on. Jon, of course, couldn’t see down to what the number read; his blond and grey bushy beard, enormous shelf-like pecs, and round, hard gut blocked his view. “Wow bullpup, we finally did it. We passed the limit!” Austin said excitedly. “Over 3000 pounds officially, pup. Goddamn you’ve been growing FAST lately!” Austin said as he reached up and smacked Jon’s round, meaty ass that protruded from the tight straps of his jock. “You don’t seem to be slowing down, pup, you just keep growing more and more!” Jon stepped back off of the scale and looked down at his Sir. He grinned through his pup mask, cocked his head to one side, and brought his fists together. He flexed hard, the fur of his pecs curling into wet rings, sweat dripping down off his huge, meaty nips onto Austin. “Bigger?” Jon grunted, knowing the answer but still wanting to hear it from his master. “That’s right, bull, bigger than ever, growing so much for me like a good pup,” Austin cooed, reaching up to rub Jon’s round, solid gut and furry, sweaty chest, which he couldn’t quite reach. “Still gotta keep getting bigger though!” “WWRROOOOOF!!” bellowed the big daddy muscle bear. “BIGGER!” He straightened to his full height. Jon’s throbbing bulge strained his jock strap and threatened to rip it open. Austin walked up onto the deck and gestured for Jon to follow him on the ground. The deck was about two feet raised up off the ground, which gave him a little more height. The wooden railing on the deck was still in the way though. “Tear out this railing, pup,” Austin said. Jon reached down and grabbed the railing at the base where it connected with the deck boards and tugged up hard with a grunt. The railing tore out with a loud snap. He did this one-by-one until the whole thing was disconnected. “Destroy it, pup, tear it all apart,” Austin demanded, rubbing his erection as he watched his big stepdad manhandle the heavy deck wood. “RRROOWWFF!” Jon boomed happily, then brought his fists down on the deck railing hard. Wood splintered and the deck shook. Jon grunted as he grabbed the top railing and pushed down and in, pressing and snapping the wood together like an accordion. He tossed half of it into the yard, laughing and grunting, then shifted over and did the same on the rest of it, relishing the opportunity to use his strength without holding back, his muscles tensing and bulging, veins throbbing as he destroyed the deck railing in seconds. “That’s my pup, big and strong!” Austin said. “Down on your knees, pup, now,” Austin ordered. Jon thumped down to the ground, the earth shaking as his tonnage dropped hard. He was kneeling in front of Austin, who was almost at eye level now. Jon’s gut surged forward onto the deck, his bulge pressing the side of the porch, his wide shoulders, harness-bound chest, and massive arms filling Austin’s field of view. “Flex for me, pup, show me those muscles,” Austin said, stepping closer to Jon. Jon raised his arms up and flexed his biceps, the round, hard peaks exploding up like mountains. Every inch of his torso was covered in dense, dirty blond fur, matted and curled by sweat. Jon’s pits were exposed as he flexed, and Austin was assaulted by the heady, cloying stink of Jon’s musk. “This new cycle has you smelling extra good, pup,” Austin said as he stepped closer, reached up, and squeezed the impossibly huge biceps. He buried his face in Jon’s left pit and huffed deeply, smearing bullpup sweat all over his nose. “Mmmph yeah that’s it, such a good pup. Big stepdad muscle bull. Who would have thought you’d ever be THIS big nine months ago, huh?” Austin said, feeling high on the distilled testosterone stench of Jon’s wet, furry pits. “Arrrrawarruff!” Jon rumbled as he brought his arms down, trapping his Sir in his deep, furry pit. “Am I a big bull pup now, Sir?” Jon asked, his voice muffled in the neoprene and leather mask. “Yes, bull, but not big enough… never big enough!” Austin said, his own voice muffled by Jon’s furry pit, his hands wandering over to Jon’s immense chest, his fingers running through the dense fur and long beard trailing against Jon’s pecs. He grabbed the thick, sturdy leather of the harness straps and pulled hard, but Jon didn’t budge. He was so heavy, too sturdy, too strong. “Gotta grow bigger for my master,” Jon whispered, his eyes closed, every touch from Austin sending fireworks of pleasure up his spine. His cock throbbed and pushed up and out further from his jock strap, belching up more pre. He squeezed Austin into a tighter headlock and growled until Austin tapped his big arm, signaling him to let go and come up for air. “Need to mark my territory, bull. You’re mine now. Isn’t that right?” Austin said, huffing Jon’s stink against his upper lip, his hands rubbing more frantically against Jon’s giant body, exploring the wide v-shaped lats and trailing down to his round, hard, furry gut. Jon sighed contentedly when he heard those words. “Arrroooof, mmmrrrooof!” Jon breathed, then brought his arms around Austin and pressed the smaller man against his big body. Austin tugged down on the harness again, clinking the padlock against the central ring of the harness. “Kiss me, pup, now, hard!” Austin said, just as desperate to make Jon feel good as Jon was to make his master feel good. Jon leaned down and nuzzled his Sir, their tongues wrestling as they kissed hard and sloppy, their beards brushing against each other roughly. “Taste my hole,” Austin demanded, and Jon obeyed. Jon grunted as he grabbed on to Austin’s dress pants and tore them apart, ripping and shredding and tearing until they fell to the ground, revealing Austin’s hard 8” cock and bubble butt. Austin had grown thicker and more muscular over the last few months training and eating with Jon, and he looked sexier than ever. Austin bent over and turned around, revealing his tight, furry hole. It was sweaty and musky, which now started to mix with the light rain that began to fall, coating them both. “MMMPH, grrrff!” Jon growled as he dove into Austin’s meaty ass, his pup mask snout pushing his cheeks apart to get to Austin’s tight hole. Jon’s thick, powerful tongue reached up and dragged slowly against Austin’s hole, causing the smaller man to shiver and groan. Jon pushed his tongue in harder, insistent, pressing past any resistance and penetrating his Sir. Even his tongue had grown bigger and stronger over the last few months! Slurping and sighing happily, sniffing master’s deep, sweaty musk, Jon ate Austin’s furry hole relentlessly, pushing him hard so Austin had to brace himself against the porch. Jon buried his nose deep in his master’s crack and then shook his face back and forth, his metal chain clinking around like when a wet dog shakes himself to get dry, sending another wave of stimulation surging through his Sir’s tight, muscular body. “Mmmmph, grrrfff, mmmmlllaaahhh!” Jon growled as he pushed his tongue in deeper, deeper, fucking his Sir’s hole with his huge tongue, slurping up every morsel of football jock hole he could get. “Lift me up, pup!” Austin groaned. Jon backed up, removing his tongue from Austin’s ass, and stood back up to his full height. He reached down and Jon’s huge, calloused hands wrapped around Austin and lifted him up effortlessly. Austin straddled Jon’s thick bull neck and massive traps with his legs, his ass resting on Jon’s chest-like pecs, his cock right in front of Jon’s pup snout. Austin looked down at Jon’s intense, focused, pleading eyes through the pup hood, his own cock throbbing and leaking, rain dripping down onto both of them. “Get your tongue back in there, pup, I need more,” Austin commanded, and Jon lifted and pressed Austin’s 250lbs like it was nothing. He raised Austin up, leaned his head back, and slurped out with his tongue, lapping up against the tight, sweaty, furry hole of his Sir. “Ssssslluurrrp, mrraraahahhhh, mrroooof!” Jon grunted and breathed as he slurped and licked. He lowered Austin down until Austin’s weight was fully pressed down on his mouth and tongue, allowing him to push in even deeper and rub his master’s jock stink all over his mouth and pup mask. “Oh god, yes pup, eat my hole, making your Sir feel SO good,” Austin moaned. He reached down and steadied himself on the smooth, dark neoprene of Jon’s pup hood, which was becoming more slippery as the rain increased in intensity. After several minutes of this, Austin had Jon put him back down on the deck. “Back on all fours, pup. Head up, good,” Austin ordered, Jon dutifully moving however his master ordered. “Turn around, pup, let me see that ass,” Austin said, breathing heavily as he still felt the stretched-out presence of Jon’s tongue in his butt. “WRROOOOF!” Jon rumbled as he rotated around, his knees and fists pressing into the worn-down grass and dirt, which was starting to get muddy as the rain came down. He planted himself facing away from Austin, head held up high, his wide, furry, muscular glutes bowing out round to the sides and towards Austin. His enormous hamstrings framed his round, heavy balls, which were barely contained in his oversized jock strap. His silicone butt plug tail was enormous, three feet long and as thick around as Austin’s upper arm at its widest point; it bobbed back and forth, up and down as Jon parked his ass in front of Austin. “Time to remove your tail, pup,” Austin said teasingly. Jon groaned as he felt Austin’s rough hands rake across the edges of the tight, filling plug. Austin pulled with all his might, and the massive plug slowly inched out, dragging across the inside of Jon’s hole, slick and wet. Jon bellowed as the huge plug came out, the heavy black tail thumping onto the deck next to Austin; the custom-made item was deceptively heavy. Left behind was Jon’s twitching, furry, pink, stretched-out pup hole, framed by Jon’s jock strap. “Get that ass up in the air more,” Austin said, stepping closer to his bullpup and pressing his face against Jon’s deep, furry crack. Austin licked and huffed his pup’s musky hole, causing it to twitch and pulse more. “AarrOOOOF!!” Jon rumbled, squirming and groaning as his Sir worked his hole. “MmMMMRPH, aaarrUUUFF, FUUUCK,” he groaned as he pressed his ass back harder towards the deck, his boots and knees digging into the muddy ground, his fists clutching a handful of grass and tearing it up as pleasure electrified his body. Austin rubbed his beard over Jon’s sensitive hole, licked up and down, in and out, all around, making his bullpup squirm and whine and bark. He came up for air with a gasp, the heady stink of his pup’s sweaty musk covering every inch of his face, breathing it in like perfume. “Drop that ass, pup, your Sir needs to plant his seed now,” Austin growled. Jon obeyed, dropping lower so his Sir could get at the right angle. He whimpered and twitched and panted in anticipation. He could feel his Sir’s hard, wet cock pressing against the outside of his hole. He could feel his Sir’s muscular torso leaning against his round, hairy ass, could feel his knees pressing against his hard hamstrings, could feel his arms reaching up to just barely grab on to his heavy leather harness and pull down and back. “You want your Sir’s cock?” Austin growled as he ground against Jon’s furry, sweaty crack, the rain mixing with the pre and sweat to make it slick. “Mmmrrrphhh, mmmm!” Jon whined desperately, his ass wiggling back and forth. “You think you deserve your Sir’s load?” Austin teased, pressing against Jon’s hole, right on the doorstep. “Uuurrrfff, arf, mmmh!” Jon begged, pressing back against the cock head that pressed against his pucker, small to his perception but powerful in what it meant to the two of them. “Such a good pup, you DO deserve your Sir’s cock!” Austin roared as he punched his way inside of Jon. “AAARRRUUUUUUFF!!” Jon bellowed as Austin thrust inside of him. His powerful glutes wrapped around Austin’s cock and squeezed tightly. “My big GROWING bull, all mine!” Austin growled as he started pounding into his bullpup with reckless abandon. Jon’s hole gripped his Sir’s cock, fitting together perfectly. Jon grunted and growled as his master filled him up; there was nothing more satisfying than feeling Austin inside of him, being this close, enjoying the fruits of Jon’s labor. Serving his master and making him happy was as gratifying as sex, as necessary as breathing to Jon now. Austin’s lust-filled grunts and moans sent shivers of happiness down Jon’s muscular spine, and he pushed back in time to Austin’s thrusts to increase their mutual pleasure. Jon planted his fists harder into the wet grass, sinking them into the ground to gain more traction as Austin pounded harder and harder. He raised his head proudly, arching his big back and feeling his jock-bound cock scraping against the ground, the head of it pressing hard against the ground and scraping up grass. “Feel me breeding you hard, bull?” Austin grunted through gritted teeth. He panted and pushed his cock deeper, more aggressively, roughly. He knew his big stepdad could take any kind of force he put into it. “GRRRUUUFFFF, MMMMPH!” Jon growled. His harness and chain jingled steadily as Austin’s pounding cock sent shivers through his big body. Rain and sweat dripped off of him, slicking up the dense fur covering his back and shoulders. “Sir needs to mark his territory, bull,” Austin groaned. Jon growled deeply, his voice resonating in Austin’s chest. “Sir needs to keep his pup’s hole full of his seed so you know you’re mine,” Austin breathed, his cock throbbing and swelling, his balls growing tighter and more sensitive. Jon bellowed and groaned unintelligibly in response, pushing back even harder on Austin, almost knocking him over, but Austin was able to brace himself. Austin reached up and gripped Jon’s harness harder. He thrust in deeper than ever, deeper than Jon had ever felt, and something in him broke; happiness, completion, satisfaction, and euphoria washed over him. His hole clamped down tighter around his master’s cock. “Yeah, take it!” Austin breathed, slowing his rhythm as he took in the full, monumental scope of the wide, muscular back and huge, powerful ass gripping his cock. “Take my fucking load, bull, unnnngggg!” Austin groaned as he felt Jon’s hole squeeze his cock and milk the cum out of him like a suction hose. Jon threw his head back and howled into the sky, rain pattering off his pup mask, his own cock leaking into the wet ground and digging up more dirt, his huge ass threatening to knock Austin over.

Austin shows off his growing stepdad to a shocked audience. Chapter 13 — Graduation Ceremony The auditorium on campus was an old, modest building that dated back to the 1950s. Parents, siblings, and faculty members filed in as graduation approached, the hubbub of excitement filling the air as hundreds of Austin’s fellow graduates gathered. Austin approached the building confidently, wearing his cap and gown which felt flowy but warm in the late May sunshine. People in front of him weren’t looking at Austin, though. They were turning, confused then shocked, at the 12-foot-tall man hooked on to a leash and trailing behind Austin, looming over everyone. Jon waddled along behind Austin, his metal chain necklace linked on to a long leash which Austin held tightly. The ground rumbled softly every time his leather boots hit the pavement. Jon saw himself in the reflection of a nearby building and grinned; thick, custom black leather boots, long socks that accentuated his bulging calves, an over-stuffed jock strap that strained to contain his massive balls and sleeping cock, a black leather bulldog harness and bicep straps that dug into his thick muscles sitting next to the heavy, thick galvanized steel chain link necklace that glistened in the sun and held his heavy padlock, and his pup mask. He watched in the glass as his huge ass bounced up and down as he walked, the silicone pup tail butt plug he had sticking out the back of his jockstrap wagging along as he walked. He felt the way his thick, sweaty thighs rubbed against each other, pushing his huge bulge to a more prominent position. Not watching where he was going, Jon suddenly heard a woman gasp in front of him and looked down at her. Jon planted himself in a wide stance, straddling the woman and looking down at her over his mountainous pecs and gut. “Arrooo?” he intoned and cocked his head, lifting up his arms up to his chest in a hello gesture, his biceps flexing into their full size. She yelped in fear, then turned and walked away as quickly as she should. Austin tugged on the leash, pulling Jon along faster. “People seem really impressed by you, pup! Why don’t you give them a show,” Austin said as he looked back at his stepdad. “AAROOOOF!” Jon replied. He took a deep breath, feeling the leather straps pressing tighter against his expanding chest, and then raised his arms up, exposing his sweaty, hairy pits. He lowered his arms into a double bicep pose as he exhaled, smelling the remains of the gainer shake he had for breakfast in his pup hood, and flexed hard. “GGGRRRRRFFFFF!” he boomed as he looked around and saw everyone’s stunned, confused faces. “Good bull, you’re looking bigger than ever today,” Austin said as he stopped and turned to admire his giant stepdad. In the weeks since Jon had moved in, he had grown faster and faster, his weight exploding exponentially, outgrowing the normal confines of the house and beyond any previous human limit. Austin’s lifting and diet plan, combined with Austin’s mental influence, had produced extraordinary results. He turned to Jon and tossed a treat up to him, a chocolate protein bar, which Jon eagerly gobbled up through the mouth hole of his mask in a single bite. “Mmmph, rrawff!” Jon replied happily and pressed closer to his Sir, his enormous jock strap bulge bumping against Austin’s head and mussing up his hair. “Not now, pup, you have to wait until later,” Austin said as he stumbled, reaching up to brush away the enormous bulge. Even a slight nudge like that carried a lot of force when it was coming from a man who weighed over 3000 pounds. Jon whined but backed up, reaching down to adjust his package and thickening cock. “I have to head in to get in line now, pup,” Austin said. He gestured “down” for Jon, and the big pup dropped do his knees and then on to all fours, his ass up in the air for everyone behind them to see. Austin gave his long beard some scritches, admiring how well Jon took care of it, the dirty blond mass of fur smooth and clean. Jon sighed contentedly as his master rubbed his chin. “Go find a seat inside and cheer me on when I get on stage, ok?” “RAAARFF!” Jon replied and wiggled his huge butt, muscle and beef jiggling around on his massive frame. He stood back up and then stepped forward and headed for the entrance, his round belly bouncing against his jock bulge, a sheen of slick sweat covering his chest from the hot sun. Jon reached the doors and found he couldn’t fit. Normal doors were no good for a man his stature anymore, even double doors like these. He went to the entrance on the side that few people were using and dropped to his knees, his bare ass on display for everyone behind him, the sweat and funk of his furry crack radiating out from it, his tail wagging and bobbing up and down. His master needed him inside, so he was going to find a way in no matter what. He grabbed one door in each hand and yanked hard. Each of them ripped off the hinges like they were connected to the frame with staples. He tossed them aside and bent down to look, cocking his head and grunting. The height of the door frame was the problem. He reached in the doorway with both hands and gripped the metal and brick entryway. He pulled hard, and the entire wall above the doorway split with a cracking sound. He pulled again, harder, and bricks started falling away. He continued pulling back and forth until the entire wall gave way. He cleared away the debris and started punching away at the sides and top of the bigger, taller entrance, destruction raining down, his huge fists unharmed, each punch punctuated with a satisfied grunt or ruff. Other graduation attendees and organizers could only stand aside in shock and horror at the power of his giant man. Finished with his work, Jon stood back up to his full height, sweat dripping and running down his chest, back, and flanks. He was able to comfortably walk through the entrance now, which he did. Inside, stunned graduation attendees turned. Some screamed at the sight of the giant muscle pup wearing only boots, a jock, a harness and a mask. A wave of heavy jock BO musk entered with Jon, quickly filling up the entire auditorium and making it smell like a football team locker room, funky and heady and sweaty. Jon ignored their reaction and made a beeline for the open seats in the front row, not watching very carefully at the little people down by his knees. Jon positioned himself front and center, then lowered himself into the seats. His giant frame spread across 6 metal chairs, each of which groaned and deformed as 3000lbs of muscle bear settled in, blocking the view of everyone behind him. He spread his legs wide, giving plenty of room for his massive balls and cock, taking up even more space. His gut folded and bulged out over his jockstrap as he sat, creating a shelf for his enormous pecs to rest on. His dripping sweat started to dry in the air conditioned room. Soon, graduation started with speeches and ceremony. Each person who got up to speak seemed unnerved by Jon’s presence, but he didn’t care. He was just excited to see his Sir walk across the stage and get the diploma he had worked so hard for. Jon was so proud of him, as his stepdad and his bullpup. He couldn’t wait to reward his master for his hard work and help him feel good later tonight. His cock throbbed just thinking about it. Eventually, they started inviting graduates up on stage, starting with the highest level of honors. Jon’s heart jumped when he saw Austin on stage, one of the tallest and certainly the biggest, most muscular of all his fellow graduates at 6’0” and 250lbs. Living together had caused Austin to grow bigger as well, and he was now the thickest, most muscular he had ever been. Even the long black robe couldn’t totally hide his bulging muscles, Jon noticed, especially his traps and arms. Jon’s cock stirred to life in his jock, shifting and thickening quickly. He reached down and adjusted himself roughly, then raised his hand up to smell his own powerful jock musk. He huffed it and growled contentedly. They called Austin’s name, and he confidently walked across the stage, grinning down at his stepdad. Jon’s heart soared, overwhelmed with pride for his son, for his Sir. “THAT’S MY BOY!” Jon stood up and bellowed, causing many in the audience to gasp and the people onstage to flinch. Jon clapped loudly, his huge hands resonant, booming claps that made people’s chests vibrate. Austin just smiled wider. Austin took his diploma, then looked down at his pup. “Get up here, pup, I need you!” Austin commanded, and his pup obeyed. Jon leaped up onto the stage in a single bound, an impressive feat for such a large man, and suddenly the giant was on stage. The crowd gasped and a murmur of concerned and scandalized conversation filled the auditorium. Jon bent down and scooped his son up in one fluid motion, wrapping two enormous, thick, muscular arms around Austin and lifting him up off the ground. He pressed Austin against his chest in a massive bear hug, squeezing the air out of him, smearing bull sweat all over Austin’s graduation gown. Austin tapped Jon to let him know that was enough, a silent signal they had developed as Jon grew and grew, and the big stepdad put Austin down. Austin caught his breath and looked up. Jon brought his fists together and flexed as he looked down as his Sir, his huge furry pecs mashing together, the leather straps of his harness straining across his traps and delts. He grinned and his jock throbbed. Austin grabbed the mic from the podium and addressed the crowd. “Thank you everyone for your kind support and words today. I wanted to introduce you to my step-father, my obedient bullpup Jon. He’s supported me and grown for me so much this year, haven’t you pup?” Austin said, wrapping his arm around Jon’s immense left thigh and hugging it. Jon faced the audience, his crinkled eyes looking out from his pup mask, his long white-blond beard spreading down onto his enormous chest. “GRRRUUUUFFFF!” he boomed proudly, sticking his chest out more. The weighty leather boots made the wooden stage creak ominously. “That’s my pup! Now how about you show these folks what you can do,” Austin said, and stepped away from Jon, gesturing him to get in position to do some tricks. Jon recognized it right away and thumped down to get on all fours. “Lower!” Austin commanded. “Barowrow!” Jon grunted and he sunk down lower, his forehead bumped down on the stage. “Good boy,” Austin said. “Wag your tail!” Jon raised his huge, wide ass higher up into the air and wiggled it back and forth, the silicone tail wagging in the air happily, his leather boots creaking as his heavy weight shifted. “Good, now crawl forward,” Austin said, and Jon shimmied forward, his big boots shifting forward and his forearms pressing against the stage as he got closer to Austin. Some members of the audience tentatively clapped, others yelled in protest. All eyes were on big Jon. “Roll over!” Austin said with a smirk. He looked over to the officiants still on the stage. “I might move if I were you!” Jon flopped to the ground, his huge gut slamming down hard, causing the whole room to boom and shake, causing the audience to gasp again. He grunted and rolled to his left, his tremendous mass shifting around with shocking speed and agility as he rolled, smearing sweat and pre-cum all over the floor of the stage. Jon returned back to his starting position on all fours, his knees and fists pressing divots into the wood of the stage. “Good pup! Now speak nice and loud to all these fine people watching you!” Austin said and then covered his ears. “AHHWWRRRROOOOOOOOOF!!!” Jon boomed as loudly as his could, his deep voice shaking the windows and vibrating peoples’ chests. The audience chuckled nervously, causing Jon to wonder what they were laughing at. Jon’s cock bulged out bigger and thicker though, stimulated by following Austin’s commands in front of all those people, the wet spot on his jock spreading wider and wetter. “Ok pup, sit up,” Austin said, stepping closer. Jon grunted and rose up, sitting back on his heels with surprising flexibility for a man as thick and powerful as he was. His massive bulge stood out prominently. “Get hard for me, pup,” Austin commanded. “Now, in front of everyone.” “Barooorururuff!” Jon grunted, and his massive cock throbbed harder and bigger fast without him even having to touch it. His jock strained and stretched to contain the swelling bulge, his balls filling up the confines, his cock swelling longer and thicker with each throbbing heartbeat until eventually the tip of his giant cock poked out from the top. Master’s command was all he needed to get hard now. “Oohhhh, fuuuck, ruuuufff,” Jon groaned as his cock continued to swell. Clear precum bubbled and oozed out of the tip of his huge mushroom head, leaking out onto the stage. His cock head was as big around as a navel orange. The audience groaned and yelled in shock and protest, some getting up to leave the ceremony altogether. Austin stepped closer to the huge bulge and licked it, slurping up the sweet-tasting pre, getting it on his mustache and chin. “Mmph you taste so good, pup. Kiss me hard, now,” Austin demanded. He looked up at his pup and Jon knew what to do. Jon bent down and grabbed the smaller man from under his armpits and lifted up. His 250lbs weighed nothing to him. Jon brought Austin up to his pup hood-covered face and opened his mouth through the slit at the bottom of the mask, and the two men kissed passionately. Their tongues wrestled, Jon’s bigger and thicker but Austin’s aggressive and assertive. Jon tasted his own pre on Austin’s lips and his cock throbbed again, another splash of precum oozing onto the stage. At this point, the audience had had enough and started heading to the exits, shocked and bewildered by this raunchy display. Austin pulled back for a moment. “All of these people are witnessing the bond, the love that we have,” he whispered intensely to Jon, both of them breathing hard and sweating, Jon’s huge hands digging into Austin’s chest and back. “Marveling at your devotion to me, pup, your willingness to do anything for your Sir. They’re so jealous of what we have, pup. You make me so proud,” Austin growled as he leaned in for another kiss. Jon growled and moaned as his Sir kissed him harder, his heart overwhelmed with love. After their kiss, Austin had Jon put him back down. Jon looked down expectantly, and his cock throbbed harder than ever, belching up a splash of pre that landed at Austin’s feet. “Arrooruoof?” Jon begged, his massive, hairy, muscular frame at odds with the plaintive, mewing sounds coming from behind his pup mask. He groped and adjusted his massive bulge. “Not yet, pup. How about we get out of here first and go home? Then we can celebrate properly,” Austin said. He motioned for Jon to lean down, and Austin linked Jon’s leash up again. “Make a path for us, bull,” Austin commanded, and Jon bounded to his feet and led the way. The crowd of people, who had become chaotic after the scene on stage, parted immediately for the giant, horny bull charging towards them. Austin gripped the leash and jogged to keep up with Jon’s huge steps. In minutes they were back at Austin’s truck. Austin unclipped Jon and told him to get in the back seat. The “back seat” in this case was the bed of the truck; Jon was far too big to ever fit in the cab of a truck or any other car for that matter. He positioned himself behind the truck, then sat gently, the frame of the truck sinking down into the rear tires as Jon settled in, trying to distribute his ton-and-a-half evenly. He hung his huge arms over the sides of the truck, as his frame was naturally wider than the whole truck, massive, muscular biceps and hairy forearms pressing against the warm metal. Austin came over to the side of the truck and rubbed Jon’s big right arm. Jon instinctively flexed, tensing the massive muscles into a round, hard peak. “When we get home, we’re going to have so much fun, pup,” Austin teased, rubbing and squeezing Jon’s huge muscles. Jon looked down at his Sir and sighed. He flexed harder. His cock leaked more precum. “Master needs to mark his territory again and fill his pup with another load now that he’s all done with college. How does that sound?” Austin purred. “GRUUURRUFFF!” Jon boomed happily as he raised his other arm up and flexed harder, breathing deep and huffing his own pit stink, eager to feel Austin’s cock inside him. Austin got in the truck and sped away as fast as he could back home.

Previous chapters: Chapter 1 Chapter 2 Chapter 3 Chapter 4 Chapter 5 Chapter 6 Chapter 7 Chapter 8 Chapter 9 Chapter 10 Chapter 11 Austin orders Jon around, then awards him with a custom-made pup hood. Jon fucks Austin in his excitement. Austin sat in the living room with his computer out, working on a paper for his final term of college, wearing short gym shorts and a tank top. The room wasn’t quiet though; the living room hummed with the sound of loud music coming from the garage, punctuated by the occasional deep grunt, metal clanging, and the whole house shaking as huge amount of weights were moved around by the giant lifting in the garage. Jon was on hour 3 of his afternoon lift and he hadn’t shown any sign of tiring. This was after 3 hours this morning of working nothing but legs; he was out working chest and shoulders now. Austin stretched his arms and realized he was thirsty. He reached for one of the thin chains around his neck, next to the padlock key he wore everywhere, and brought a basketball whistle up to his mouth. He blew sharply, the high-pitched sound cutting through any sort of music or noise in the house. Austin felt the ground shake and Jon’s booming voice rumbled through the house. “COMING, SIR!” Within seconds, Austin could hear and feel the booming rumble of his massive stepdad bounding into the room like an excited puppy, the house shaking as nearly a ton of muscledad thumped into the living room from the garage. Jon’s head scraped against the ceiling as he ducked into the living room, his naked body dripping with sweat from lifting, his face lighting up in excitement as he saw Austin looking at him expectantly. “Sir!” he boomed as his cock twitched, then dropped to his knees in front of Austin and set his sweaty hand on Austin’s. “What do you need, Master?” Jon said, looking in Austin’s eyes intently, eager to serve. Austin had recently cut Jon’s hair into a crisp, short mohawk and trimmed his beard. The beard looked sharp and angular and came down to his nipples, where it mixed together with his dense chest fur, which was currently matted down with sweat. Jon’s musk washed over Austin like a wave as his pup awaited his order. “Get me a beer, pup,” Austin said. “I’m thirsty.” Jon grinned and bounded to his feet, his heavy metal chain clinking, his head bumping into the ceiling and sending down a rain of plaster and spreading cracks across it. “Yes Sir!” he rumbled before galloping to the kitchen. He returned shortly with a can of lager, cracking it open for Austin carefully with a fingernail, the can looking comically small in Jon’s enormous hands. He handed it to Austin. “Thank you, pup, you listen so well,” Austin said, reaching out and rubbing his hand over Jon’s huge thigh. Jon flexed it in response, making it swell out harder and rounder. Austin’s hand came away coated with sweat, which he rubbed on his own tank top. “Heh, thank you Sir! Can I get you anything else?” Jon boomed from above as he looked down as his little Sir. His cock stiffened as he did, sweat dripping down onto the carpet like he was fresh out of the shower, eager to serve his master. “No bullpup, now get back to lifting!” Austin said as he turned his attention back to his computer. “Yes Sir!” Jon said seriously and headed back to the garage. In a few seconds, the familiar clanking of metal and deep, loud grunting resumed. Austin drank his beer and got back to work on his paper, but a couple minutes later he realized he was hungry too. He was having a hard time focusing, especially after Jon had visited. Austin had trained Jon well over the last couple months to come when called and do as he said, and Jon was more than happy to oblige. The whistle had proven to be an exciting addition to their at-home dynamic. Austin blew the whistle again, and once again the huge muscle bear rumbled into the living room. This time, Jon’s cock was semi-hard and leaking; a string of precum oozed out from his huge mushroom head and smeared against his sweaty thighs. He dropped to his knees again and rested his huge chin on Austin’s knees. “Hi pup, I need a snack to go with this beer. Get me one of my meal prep kits,” Austin said as he reached forward and ran his hand through his bull’s spiky mohawk. A mist of sweat bloomed from Jon’s hair as Austin’s rubbed it. Jon grinned, then rose to his full height again. “Coming right up, Sir!” he rumbled, sweat dripping down on Austin. “You look so cute down there in your chair, Sir,” Jon said. His cock pulsed and thickened as he looked down at Austin, a drop of pre drooling out of his slit. “Thank you, pup,” Austin said as he reached out and dabbed up the pre onto his finger, causing Jon to shudder in pleasure. Austin licked it up, savoring the sweet salty flavor. “Now go fetch me my food,” Austin said, keeping Jon focused on the task before losing him to his raging libido. It had been 4 hours since the big man had last cum, and Austin knew his balls would need to be drained again soon. Jon shook his head to refocus, then turned to go to the kitchen. A few minutes later, he returned, dropped to his knees, and delivered a hot meal prep container full of rice, chicken, and broccoli, ready to be eaten. “Good bullpup! Make sure you’re eating too, Jon. Did you have the jug of gainer shake I left for you for your afternoon lift?” Austin asked as Jon breathed heavily on him. “Yes, of course Sir! I’m definitely getting hungry for dinner soon, though,” Jon said. “What are we having tonight?” he asked. “Meat, big guy. You’ll see,” Austin said, grinning up at his stepdad. “I’m gonna go upstairs and take a little rest after my snack,” he said as he got up with his beer and food and stood next to Jon. Austin had to crane his neck to look up at his dad now. Jon reached down to scratch his hairy bush, bouncing his stiffening cock around as he did. “Sounds good, little Sir,” Jon rumbled, twisting his neck around to see over his massive chest and gut to look down at his stepson. “Please let me know if you need anything, I want to help make you feel good,” Jon said, a twinge of desperate longing in his voice. His cock bulged up bigger, stiffening and rising up to his belly button; it oozed out another dribble of precum, which dripped down to the carpet. “That’s what your Sir likes to hear,” Austin said. He reached up and gave Jon’s cock a good, hard squeeze, causing more pre to burble out of it. Jon gasped and shivered. “Now go finish your workout,” Austin ordered before walking by the giant and heading upstairs to their bedroom. “Yes Sir!” Jon boomed and then waddled back to the garage. Austin grinned; his stepdad was completely obedient to him now, and the two of them were both very happy together. He wanted to show his appreciation to Jon and bond them closer together. He had been waiting for this moment. Over the last several months, their relationship had grown more and more intense as Jon grew bigger and bigger, surging taller, thicker, and wider every day. They did everything together and were totally devoted to each other to help reach their mutual goals and make each other happy. After the last couple whistle blows, Austin felt even more strongly than ever that it was time to give Jon his present. Austin made his preparations and finished his food and beer, then once again whistled for Jon. His obedient bullpup bounded up the stairs, then wedged himself into the door, smearing sweat all over the door frame, his head cracking the wood of the frame before emerging into the bedroom. “Sir? What’s all this?” Jon asked as he looked at Austin, who was wearing his leather harness and a jock strap. “Jon, you’ve made such incredible progress over the last 8 months, growing both physically and emotionally for me, learning to trust and love me as we have bonded,” Austin said as he stepped closer to Jon. “Get on all fours, pup,” Austin ordered, pointing down to the carpet. Jon obeyed immediately, thumping down to the floor on all fours, eagerly looking at his Sir, awaiting instructions. Austin leaned down to Jon’s ear. “I can’t imagine life without you now, Jon. We just keep growing more intensely close as you grow bigger and bigger. You feel it too, right?” Austin said, his voice in a deep whisper. Jon shuddered and took a deep breath. “Yes Sir, so much, more intense every day. I live to serve you, Sir, and I’ve never felt better about anything in my life. I have such a clear purpose, and it feels so good to lift, eat, and grow every day as I make you happy,” Jon said, his voice wavering. “I… I want to be your bullpup forever, Sir,” Jon whispered, on the edge of tears. “Good, pup, good. Look at how big you’ve grown,” Austin said as he walked around Jon’s enormous frame, rubbing his hand over the vast expanse of Jon’s hairy, sweaty back, squeezing the huge, round form of his ass, before trailing his hand down Jon’s hamstring. “Truly a freak, bigger than I could have dreamed of. You were made for growing and obeying, weren’t you?” Austin said as he completed his loop. “I was made to grow and serve you, Sir,” Jon echoed, his voice quivering. “Well pup, I’m glad you feel that way too. Show me your devotion,” Austin said before positioning himself in front of Jon. Austin lowered his jock strap and pulled out his hard, thick rod, leaking precum, red and angry-looking. “Suck a load out of your master,” Austin commanded. Jon obeyed. He surged forward aggressively, gobbling up Austin’s cock and taking it in balls deep all at once. The force of it was enough to knock Austin over, and he was suddenly pinned, helpless under the power of Jon’s mouth and hands. The force of Jon’s suction was intense, and Jon hummed and purred as he went to town on his Sir’s cock. “Aww fuck yeah bullpup, such a good boy, you need Master’s seed don’t you?” Austin groaned, the power of Jon’s tongue and sucking on the verge of pain. “Mmmph, mmmm!” Jon grunted as he sucked harder and faster. “Slow down pup, that’s it, get in a rhythm,” Austin said as his cock throbbed. He was so close to climax. Jon’s muscles, his musk, his obedience drove him crazy, and he was almost always ready to share his seed with his eager bullpup. Jon reached up and planted one huge hand on Austin, pinning him down to the carpet effortlessly as his mouth continued to suck and slurp. His tongue flicked and his lips tightened. On most men, Austin’s cock would have been substantial, girthy and a generous 7”. To Jon, it felt small in his oversized mouth, but it just made him want to suck and pull harder. He hummed and groaned as he tasted more precum. “Such a devoted bullpup!” Austin groaned as he got closer to shooting his load. “Gonna make me, ung, make me shoot such a, ahhhhh, big fuckin’ LOAD—!” Austin bellowed as he came, and Jon greedily gulped up every drop until Austin was thoroughly drained. Jon helped Austin get to his feet when he was done, then sat back on his heels. Even seated like that, he was taller than Austin. “How was that, Sir?” Jon said, gently rubbing Austin’s hair with his huge mitt. “Good job pup, you’re so good at that now!” Austin said, steadying himself against Jon’s massive shoulders. He turned to get the box at the foot of the bed. “I got this for you, custom made, in your favorite colors,” Austin said as opened the box. “Oh, Sir! What is it?” he rumbled, tears welling in his eyes. He opened it and gasped. “Really, Sir!?” “Yup. Put them on,” Austin said giving Jon space. Jon pulled did just that, and in a moment a black, green, and orange neoprene pup hood covered Jon’s head and face, his long beard trailing out of the bottom, his excited eyes beaming down at Austin through the holes in the mask, curved bull horns in place of the usual pup ears of his hood. A matching leather harness wrapped tight around his enormous chest, hugging his pecs, shoulders, and traps in all the right places. Jon huffed the intense smells of neoprene and leather that suddenly filled the room and his cock throbbed. “It’s PERFECT, Sir!” Jon grunted, his voice muffled in the pup hood. He turned and looked in the floor-to-ceiling mirror that Austin had installed in their bedroom a couple months ago. “I had both measured to fit your supersized body, bullpup. They hardly believed me when I shared your chest size and hood size and thought it was a joke.” Austin said, grinning at how happy Jon was. “They’re both adjustable and fairly stretchy to keep up with your continued growth, at least for a little while!” “BaarrRROOOOF!” Jon bellowed as he saw himself. His cock throbbed harder and harder, growing longer and stiffer as he stepped closer to the mirror. “Mmmmmph, grrrph, rrrawwwwrph!” he grunted as he flexed his left bicep and rubbed his mask against the sweaty bulging muscle. “ARRFFF!” Jon said as he turned back to Austin and bounded towards him. “Heh, bullpup likes it I see!” Austin said as Jon reached down and effortlessly lifted him up, carrying him and rubbing his mask and beard all over Austin to express his love. “RRRUUUFFFF, ARRFF, GRRRRFF!” Jon rumbled before tackling Austin on to the bed, the combined weight of them both causing the re-inforced bed to groan and the house to shake. Jon nuzzled against Austin, rubbing his pup hood and beard and chest and hands all over his master’s little body, pinning him with his own bigger body, crushing him under nearly a ton of beefy muscle. “AAAARRROOOOFFF, GRRRPH, MMMPH, YEAAAHHHH!” Jon grunted, hardly capable of words now, letting the pup space fully take over his mind. He rubbed and cuddled against Austin hard, his rock-hard cock leaking precum juice all over his little master, totally carried away. “Pup, hold on, that’s, ooof, flip over so I’m on top!” Austin grunted under the immense weight of his overly-excited bullpup. Jon stopped his grunting, wrapped his huge hands around Austin’s torso, and flipped them both around until Austin was on top of Jon. Jon cocked his head to one size as he looked up at his little Sir. “Arroo?” he grunted, then rubbed Austin back and forth on his sweaty torso. “Ruuufff, arruuuff, ggrrooooff!!” he boomed. his huge cock pressing dangerously close to Austin’s tight, furry hole. “Yes big man, I need your bullpup seed inside me now!” Austin grunted as his own hard cock rubbed against Jon’s firm, furry gut. “RRRRUUUHHH, GRRRRR!” Jon groaned as he positioned his master over his massive cock. It was as thick as Austin’s forearm with an apricot-sized head. It burped up more precum, seemingly on command as if it knew Jon needed more lubrication, then Jon rammed Austin down on it hard. “AARRROOOOOOOO!!!” Bullpup bellowed as he speared Austin, pushing in as far as it could go. “Ahhhhh godddddd!” Austin cried as he was suddenly filled with the massive cock. Jon slowed down for a moment, sensing that his master needed time to adjust to his size. The girth of his huge stepdad’s cock pushed him to his limits, and he writhed as his ass struggled to adjust to Jon’s thickness. He stabilized himself against Jon’s leather harness, his own cock throbbing and getting closer to another climax as he huffed in the scent of Jon’s musk and the leather from the harness, taking deep breaths to calm down and open his hole wider. “URRRGGG, HHUUUNNFFF, ARRRFFFF!!” Jon grunted as he stared to pick up speed again, his bull horns bouncing on his hood as he submitted deeper into pupspace. He pounded relentlessly inside his master, working up to full strength, slamming in deeper as Austin’s furry jock hole opened up wider to accept his stepdad’s massive cock, impaling the smaller man over and over again, pausing only briefly to bring both of his huge arms up into a double bicep pose, reveling in his enormity, furry pits emanating fresh waves of jock musk. Austin groaned mindlessly, holding on for the ride, his cock rubbing mercilessly against Jon’s sweaty torso. The two of them ground against each other for as long as they could stand it, Jon using his little master like a sex toy and Austin frotting his cock against Jon’s enormous, meaty gut and chest, Jon’s metal chain clanking against his new harness. Austin groaned as his cock shot another load, smearing cum all over the big bull’s belly and pecs and harness, mixing with Jon’s sweat. His hole clamped down harder around Jon’s tree trunk cock. “AARRRROOOOOO!!!!!” Jon bellowed as he exploded inside Austin. Jon could feel his insides bloat with cum as Jon unloaded inside of him, jets of hot bullpup cum filling him up. Jon kept howling until he was completely drained, his huge balls pumping out cream for over a minute. Finally, he lifted Austin off of his baseball bat cock inch by inch until he popped off with a wet squelch, cum splashing down onto Jon. Jon held Austin suspended in the air over the bed. “Grruufff, arrrrfff, mmmphhhh!” bullpup Jon grunted as he pulled Austin in closer, nuzzled against him, and spread his master’s seed all over his huge body, marked with his master’s cum, honored to serve him for life.

Previous chapters: Chapter 1 Chapter 2 Chapter 3 Chapter 4 Chapter 5 Chapter 6 Chapter 7 Chapter 8 Chapter 9 Chapter 10 Jon enjoys a BIG dinner and Austin makes sure his growing stepdad gets nice and full, which gets both men worked up quite a bit. The doorbell rang right as Austin walked inside. Perfect timing! The pizza delivery guy was here. Austin had ordered it ahead in anticipation of Jon being done with his workout. “Dinner’s here!” Austin yelled. “Come into the kitchen and get ready to eat, bull!” Jon’s thunderous footsteps followed; the big man positioned himself in front of their back door, leaned down, and started wedging himself through the doorway. He had already expanded it himself accidentally weeks ago, and the half-fixed under-construction wider, taller doorway was already barely big enough to allow him to pass through. Austin watched as Jon crawled through the entrance on his hands and knees, grunting and squirming to fit his wide shoulders and round butt through the doorway, shimmying in until he was inside. Austin just watched, the front door momentarily forgotten; he loved watching his big bull struggle to fit into the normal-sized world. “Ooof!” Jon grunted as he rose to his full 10’ tall height, his head thumping into the ceiling, sending plaster dust raining down into the kitchen. He just grinned and blew some of the dust off his nose. He stepped forward and leaned against the counter, his gut and bulge flopping down onto it, post-cum from his load smearing onto the granite through his white compression shorts. His triceps flared out bigger as he leaned his weight against the counter. His gut gurgled and then groaned loudly, audible throughout the main floor of the house. “Sir, I guess I’m really ready to eat today!” Jon said with a laugh as he stared eagerly at his master. Austin opened the door to get the pizzas. “Big party?” the delivery guy said as he handed him 8 extra larges. “Heh, not exactly,” Austin said as he took them, balancing them carefully. Austin set the pizzas on the kitchen counter, the house filling up with the smell. “Alright bull, ready to eat big? You’re not gonna stop until I tell you, ok?” “Yes Sir!” Jon boomed enthusiastically. He grabbed one of the boxes, the extra large box looking so small in his huge hand, and opened it. His eyes lit up and his gut rumbled again as he saw the pizza. “Meat lovers! My favorite. Thank you, Sir, I don’t deserve all this,” Jon said. “Of course you do, big man. You’ve been working so hard lately and growing so fast for Master. You think you can finish all of these?” Jon scoffed and stepped closer to Austin, looming over him; Austin only came up to his bulging belly button. “Sir, I’ll bet you that I can finish all eight of these in less than half an hour. By myself.” the big man rumbled, looking down at Austin with a smirk. He rubbed his hairy gut, the fur scraping against his calloused hands. It responded by gurgling again, louder than before. “You’re on, pup, I’d love to see you try,” Austin said with a grin. With that, Jon grabbed a quarter of his first pizza. The meat lover’s was stacked with bacon, sausage, pepperoni, and chicken. He folded the pieces over on top of each other until they were stacked up together into one huge piece. He opened wide and took a huge bite; half of the quad slice disappeared into his maw and he chomped down on it loudly. “Mmm,” Jon groaned around a mouthful of pizza. “So good. Gotta feed the beast to grow bigger!” he said and slapped the side of his big belly. It jiggled, then rumbled some more, demanding more food. Jon opened wide and stuffed the rest into his mouth, devouring 4 slices in just two bites. “Heh, that’s right bull, keep eating,” Austin said. “Clock’s ticking! Here, use this to wash it down,” he said as he got a 6 pack of Leinie’s from the fridge and slid it over to Jon. “Mmm, yeah!” Jon boomed as he wrapped a hand around one of the cans and pulled it out. The can looked comically small in his massive paw. He carefully snapped it open, then lifted it up to his mouth, his massive arm bulging into a bicep flex as he did. He guzzled the whole can down in seconds, crushing in it his grip as he got to the end. “BBBBRRUUUPPPPP!” Jon erupted as he tossed the can aside and reached down for more pizza. Jon kept eating. It only took him five minutes to demolish the first pizza. He set the box aside and opened the second one. He tore into that one with the same ferocity as the first one, his hunger seemingly not abated at all. “Good bull, keep eating. Don’t stop until I say so,” Austin said, staring intently as his pup. “I’m always so hungry these days, Sir. Just trying to eat enough to keep growing is a lot of work, you know?” Jon said before chomping down on another stack of slices. “I know, pup. You work so hard to grow for your master, and I’m so proud of you. You really know how to put it away, huh?” Austin said, stepping closer and reaching up to rub Jon’s huge round tummy. “You’re gonna keep eating and getting bigger, right?” Jon groaned. “Yes Sir,” Jon sighed between bites, then ripped another huge piece off and kept eating. After finishing off the fourth pizza (and Austin eating a little bit of one of them), Jon paused. His breathing had become faster and more labored, and he had started sweating profusely, his bull musk filling up the kitchen along with the pizza smells. He looked over and caught his reflection in the glass of the cabinets. He rubbed his belly and chuckled. “What’s so funny, pup?” Austin said. “It’s hard to believe how big I’ve grown, Sir. I look at myself sometimes and marvel at how enormous I am,” Jon said, straightening his shoulders and swelling his chest and gut out, emphasizing his full size. “Yeah, well you should be proud of it, pup. You’ve worked hard for your gains! Tell me how much you like being big, pup,” Austin said, looking up at his submissive dad with a smirk. “I love it so much. Everything is thanks to you, Sir. Your leadership and guidance are responsible for it all,” Jon said, a quiver in his voice. “All of what, pup? Show me.” Austin ordered, motioning him to flex. “All of this,” Jon growled, then raised his arms up into a huge bicep flex until his fists bumped against the 10-foot ceiling. The round, thick peak of his arms rose up like a mountain, matched only by his bowling-ball delts and thick traps. “And this,” he continued, reaching down and rubbing a huge hand over his round, furry gut. “I’m outgrowing the damn house thanks to you, Sir!” Jon boomed excitedly. He scraped his head against the ceiling, again sending plastery powder raining down on both men. Jon’s Underarmour-bound package flopped onto the countertop again, pushing aside one of the pizza boxes. “I’d still be an average weakling without you. Look at me now! I’m the biggest man in the world!” Austin stepped closer to feel his massive muscle pup. He reached up and tugged on Jon’s thick heavy chain necklace, grabbing him by the padlock and pulling his head down to look at his master. “Are you done growing yet, pup?” “No Sir! I’ll keep growing as long as you want me to. As big as you want. Whatever it takes!” Jon rumbled, growling intensely, his voice shaking with emotion. “That’s my good pup, you make your Sir so proud,” Austin said, leaning in closer and whispering in Jon’s ear, their beards scraping together. “You’re gonna keep growing bigger and bigger until I say you’re big enough, how do you like the sound of that?” Austin purred. Jon’s big body shook, shivers of pleasure and anticipation rattling through his body. His package throbbed and a wet streak of pre smeared across the countertop. “Yes Sir, *huff*, anything for you, Sir!” he breathed desperately, pizza breath washing over Austin. “Good pups listen to their master!” Jon said, his eyes suddenly welling up with tears. He reached down, wrapped his massive arms around Austin and lifted him up in to a huge bear hug. “Gotta keep growing for my boy, for my Sir!” Jon’s furry torso scraped against Austin’s and Austin could feel the intense heat radiating off his huge body. Sweat and pizza grease smeared against Austin as the two rubbed against each other, both of their cocks throbbing. “Good pup, your master loves you very much. Now put me down,” Austin commanded. Jon took a deep breath to compose himself, his arms still wrapped around Austin. “I love you too, Master, so much,” Jon whimpered, a strange sound from such a big man, before setting Austin down. He wiped the tears away from his eyes. He was overcome with intense devotion. “Do you know how big bulls like you keep growing?” Austin asked, and motioned towards the remaining pizzas. “Gotta eat big to grow big!” Jon boomed, repeating the words that Austin had told him many times over the last 7 months. Jon scooped up another four slices of pizza, crushed them together into one big stack, and stuffed them into his mouth, cramming them all inside. *crruuunnnchhh* and suddenly all that was left in his huge hand was a line of crust. “Good pup, that’s the way. You’re looking bigger already!” Austin said, encouraging his pup, rubbing the side of his mammoth gut. Jon smacked the other side of his belly with a huge hand, slapping it repeatedly, his firm, hard gut barely shaking from the impact. He chuckled around his mouthful of pizza before swallowing it shockingly fast. “UUUURRRRPPP!” Jon belched, the deep, resonant burp making the glass on the cabinets rattle. He followed that up with several smaller burps as he reached down and cracked open another beer. He lifted it up to chug it, but in doing so his huge bulge bumped the half-empty pizza box onto the floor, sending several slices tumbling down onto the ground at Jon’s feet. “Uh oh,” Austin said, looking up at his pup knowingly. “You know my rule about wasting food, pup. What is it?” he said, flicking a nipple on Jon’s bloated pecs. Jon shivered and groaned between panting breaths. “No wasted food, no matter what,” Jon rumbled. He licked his lips and his cock throbbed again, more pre leaking through his compression shorts. “That’s right. Get down there and clean it up,” Austin said, gesturing down to the ground where the fallen pizza lay face-down on the kitchen floor. “Yes Sir,” Jon grunted. The big man, dropped down to his knees, causing the room to shake, then got down on all fours. Even on all fours, he was still almost as tall as Austin. He reached for the pizza before Austin patted him on his shoulder and shook his head. “Not like that pup,” Austin said. He came around to Jon’s front, rubbing a hand across Jon’s expansive, muscular back, feeling the lumpy ridges of his enormous traps. “With your tongue. Get every little bit that you dropped. No wasted food, no matter what,” Austin said authoritatively, looking his bull right in the eyes. Jon nodded obediently, his face flushing red, his breathing heavy. “Yes Sir!” Jon boomed, then dove down to lick up the fallen pizza off the floor, his metal chain clinking around as he did. He slurped, grunted, and moaned as he licked the floor, getting every fleck of sauce, every chunk of sausage, every crumb of crust until all that remained was a wet spot from his own spit. “Licking food off the ground, god you are such a greedy, hungry mutt aren’t you?” Austin teased, scratching the dirty blond mohawk and rubbing his fingers over Jon’s neck rolls. “I need it all, Sir, gotta have more to grow bigger for you, Sir,” Jon breathed. Jon felt dirty, but his cock leaked onto the floor, belying his true feelings. “Good bull, such a hungry pup, you make me so happy,” Austin cooed, moving his hand to Jon’s back and rubbing the bulging traps through the big bull’s back and shoulder fur, feeling the muscles twitch against his calloused hand. “Mmmph, need MORE, Sir!” Jon rumbled as he sat up, eye-level with Austin for a moment. “Still so hungry!” “Good bull, let’s keep eating then, I’m still timing you!” Austin said as he stepped closer. He rubbed his hands against Jon’s round belly and swollen pecs, every inch of him furry and sweaty. He could smell Jon’s pizza breath. He leaned in closer until he planted a firm kiss on Jon’s big lips. Jon groaned as his master kissed him. Nothing felt better than getting Austin’s approval and praise. Nothing felt better than Austin’s lips on his. Jon reached out and rubbed his big hands up and down Austin’s lean, hard body, feeling the firm muscles dance and twitch as they ground against each other in lust. Jon’s cock throbbed again, soaking his compression shorts even more. His gut groaned in hunger. “Still so HUNGRY!” Jon boomed, then stood back up to his full, towering, 10 foot tall height until his head bumped the ceiling. Austin had to back up to not get knocked over by Jon’s huge pecs, gut, and bulge as he stood. Austin looked up at his giant stepdad looming over him; there were still times that even he was shocked at how big Jon was growing. Jon reached down and resumed eating with renewed vigor, gobbling up the pizzas with obscene grunts, chewing, and growling. In just a few more minutes, Jon polished off another 3 beers and 3 more pizzas until there were only a few pieces left. The big man was huffing and puffing and his gut had swollen out rounder and fuller than before. Jon raised the last stack of 4 slices up to his mouth and crunched down on them, breathing heavily out of his nose, chewing slowly. He groaned and swallowed. “DONE!” the big man boomed, smacking his round gut loudly. A deep, resonant burp escaped his lips, and he jiggled his gut proudly in front of Austin. “Such a big meal, Sir. So full,” he groaned. He reached a big fist up and rubbed pizza grease off of his lips and mustache, then licked his hand to make sure he got every bit. But Austin knew the big bull still had more room. “Good job, pup! So proud of you. Such a BIG bull. But you took too long, bull,” Austin said, holding up his timer, which read 30 minutes and 24 seconds. “You must still have room! You’re not done yet,” Austin said, and Jon groaned. “Go over to the living room and sit down in front of the couch. I’ve got more for you coming,” Austin said, rubbing Jon’s full, furry tummy and looking up at his big pup. Jon looked exhausted and overwhelmed. He puffed out his cheeks and exhaled, which turned into a deep, rumbling burp that rose up from the depths of his belly. “Y-yes Sir,” was all the big man could manage before he lumbered off to the living room. Jon sat down heavily and spread out his legs, his tremendous gut spilling into his lap and pressing against his bulge. He closed his eyes and rested for a moment, reaching up to run his fingers across the heavy metal chain and lock that wrapped around his neck, something he did to comfort himself and remind himself of his Sir’s love. A moment later, Austin came out holding three blender containers, each one full to the brim of a vaguely brown-looking sludge and a big red funnel. “Ok bull, now let’s top off that big binge with some protein, huh?” Austin said as he set the shakes down on the coffee table and walked between Jon’s huge legs to get closer. With Jon sitting, Austin was eye level with the big bull. “Three huge, thick gainer shakes to wash down all that pizza, how does that sound?” Jon groaned and rubbed his already full belly. “Y-yes SirUUUUPPP,” Jon rumbled as his words turned into another burp. “Gotta eat big… to grow big,” he groaned. “That’s right pup. Now hold the funnel in place,” Austin ordered, handing Jon the red funnel. Jon set it against his lips and tilted his head back; they had done this routine many times before and Jon knew what to do. “Here it comes,” Austin said as he reached up and poured the thick, brown protein-rich sludge into the funnel. “Mmmmmph,” Jon moaned as the shake hit his tongue, his appetite renewed as he tasted the sweet chocolatey sludge. He drank it with shocking speed, slurping and gulping, his Adam’s apple bobbing up and down, mega-sized gulps loud and clear for Austin to hear, big lips sucking, eager for more. In mere seconds, the entire shake was gone. Austin pulled the empty blender container away, leaving Jon slurping and licking for the final drops. “Good bull, I knew you weren’t done yet,” Austin said with a smirk, smacking Jon’s round, sweaty gut. It gurgled in response, the shake filling in any gaps between the pizzas that filled up his belly. Jon breathed hard and held the funnel against his belly, letting some of the remaining shake leak against it. He closed his eyes and licked his lips then burped in satisfaction. “More…” he sighed dreamily as he rubbed the top of his belly and grinned. His cock throbbed harder, straining the elastic and threatening to escape the tight confines of his compression shorts again. He raised the funnel up into the ready position. Austin just grinned and readied the second shake. “Here it comes, bull, such a good pup growing bigger for his Sir,” Austin said as he lifted up the second shake and started pouring. Jon moaned contentedly as the second shake hit his lips and he started sucking on the funnel loudly. Austin could hardly pour fast enough to keep up with Jon’s eager gulping, the sound of which filled the room with obscene slurping, chugging, guzzling noises. Austin could see Jon’s belly swell bigger, rounder, tighter as Jon consumed every drop. It went down shockingly, unbelievably fast considering how full the big man was. Jon came up for air with a gasp, rumbling a deep chuckle as he caught his breath. He palmed his vast gut and rubbed it. “Uuufffff, Sir, huuufff, I’ve never, rruurrff, been more full,” Jon panted, feeling his upper belly. “It’s so, grrroooofff, TIGHT!” the big bull groaned. “That’s right, bull, SO tight and round, so full of growth fuel,” Austin said, rubbing Jon’s belly in wide, slow circles. “You’re doing SUCH a good job for your Sir, getting so big, so round and strong,” Austin said, heaping praise upon praise. Jon broke into a broad, exhausted grin and closed his eyes . “I don’t know if I can have any more after that,” he said between short, labored breaths. A small burp escaped from his lips and he groaned some more. “So full!” “Aww come on bull, I know you can take a little bit more,” Austin said, leaning in closer and pressing his own hard bulge against Jon’s gut. Standing, Austin was about the same height as Jon was sitting down, and his cock was at just the right height to press against Jon’s thick pecs and the top of his round, hard gut. Austin rubbed up and down against the bulky torso of his huge stepdad and groaned. “Kiss me, pup, I need to taste you,” Austin whispered. Jon grunted and grinned in response. He opened his eyes and leaned forward to kiss his Sir. They locked lips, Jon’s bigger face and beard and lips smothering Austin’s, his thick tongue easily overpowering his Sir’s aggressive embrace. Austin lowered his pants and underwear so he could rub directly against Jon’s massive chest and belly; Jon growled when he felt the slick, warm precum spreading around between his enormous pecs. They both breathed heavily through their noses and grunted and groaned, their hands exploring each others’ bodies freely, greedily, hungrily. Austin could taste the thick, sweet protein shake on Jon’s lips and relished the flavor. After being apart for months, they still savored the benefits that came from being together all the time. After what seemed like an eternity and not enough time, they separated, both of them catching their breath, both men’s cocks throbbing and leaking pre. “Mmmph, well damn you taste good, pup,” Austin said with a grin. “Yeah? What do I taste like, son?” Jon said with a smirk, his cock emerging from the top of his Underarmour, the head of it as big as Austin’s fist. Austin stepped closer until he was inches away from his stepdad’s face. “Like protein and sweat and cum and MAN,” Austin growled, rubbing his beard against Jon’s. “And knowing you’re going to grow even BIGGER has got me so worked up,” Austin said, pressing his cock against Jon’s chest again and smearing more pre around. “Y-yeah!” Jon breathed, then jerked as a belch slipped up and out of his maw. “Always bigger, always more,” Jon intoned. “Good pup. Let’s see that big bicep and let me smell you, bull,” Austin commanded. Jon obeyed. He raised up an arm and flexed his mighty bicep, exposing his hairy, sweat-matted hairy pit. A wave of Jon’s BO funk filled the living room. Austin grabbed the massive, round bicep, leaned forward, and buried his nose in Jon’s armpit, rubbing it around in the deep, sweaty, furry crevice, huffing in the heady smell and groaning with pleasure. Jon shifted his weight and reached over with his other arm to lightly press his Sir into his musky pit, holding him there and feeling his master wriggle against his firm grip. “Mmmmmph, so good,” Austin breathed as he came up for air, sniffing his own upper lip, savoring the musk that coated his beard. “Glad you like it, Sir. I think that’s getting stronger the bigger I get!” Jon said sheepishly. “Yeah? Let’s test that theory,” Austin said before rubbing his nose in the damp, furry pit cave again, huffing in the heady smell, groaning as he did. “What do you think? Muskier? Sweatier?” Jon asked as he held Austin’s head in place. Austin gasped as he came up for air. “Definitely,” he said between breaths. “The bigger you grow, the better you stink,” Austin said, grinning. “Heh, that’s right Sir!” Jon rumbled, looking quite pleased with himself. He pressed Austin against his furry pit again, forcing his Sir to get another huff of his potent bull musk. His master looked so cute desperately rubbing and licking and sniffing his deep, muscular pit. “Ruff, Sir loves my stink, and I do too,” Jon said after Austin had his fill. Jon leaned over and sniffed his own pit and sighed, enjoying his own musk. “Well if growing bigger makes you stink better, then let’s keep going, bull,” Austin said. “And to grow bigger, my bull needs to drink one more big, thick, rich gainer shake. 14,000 calories in every one of these babies, and it’s all for you, pup,” Austin breathed, his voice rising in excitement. He stepped back to grab the last pitcher. Jon breathed more heavily and reached forward to rub his drum-tight belly. “But Sir, I’—URRRPPP—I’m so full!” Jon pleaded, his belly sloshing and groaning as he adjusted his weight. “Now pup, listen to your Sir. You know you can’t say no to me,” Austin said, stepping closer with the shake. “But, but Sir I — BBRRUUAGHHH — I can’t fit, any more, huffff, food in this big belly!” Jon groaned as he palmed the vast expanse, his belly swelled out to the max, heavy and furry and round. “Good pups listen to their masters, don’t they?” Austin cooed, relentless, insistent. He returned to where he was standing before and pressed his cock against Jon’s tight belly again. “Good pups liste—BBBRUUHHHHP—listen to their masters,” Jon repeated. “And are you a good pup?” Austin said, his eyebrow raised, a confident smirk on his face. “I’m a good pup, Sir,” Jon breathed, his eyes welling with sudden emotion. He was filled with a desperate need to make Austin happy, and to do that he needed to drink that shake. He felt a second wind, and his mouth salivated in anticipation of the thick, rich liquid. He grimaced and flexed, his traps and neck bulging with muscle. “Give me more, Sir. I need MORE!!” Jon raised the funnel back up to his lips, his massive bicep flexing as he did, and he tipped his head back again. Austin wasted no time, dumping the final shake into the funnel. Jon moaned, desperate to chug it down, and he guzzled it all up faster than either of the previous shakes, his grunts and chugs turning into greedy-sounding growls. When the final shake was gone, Jon put the funnel in the container and Austin set it aside. Both of them growling and chuckling. Austin pressed his cock against Jon’s rock-hard gut and meaty pecs, and started grinding against his giant stepdad. “Such a huge, hungry, growing PUP, I’m so proud of you, Jon,” Austin breathed as he bucked against Jon, frotting aggressively against Jon’s furry beef. Austin suddenly felt something huge and hard rubbing between his legs; he looked down and saw Jon’s freed, hard cock, thick and long as a Pringles can, rubbing up and down his legs until the tip of it pressed against Austin’s tight balls. “Of course, Sir, I’d do anything for you, Sir, gotta grow BIG for you, Sir!” Jon panted, working into a frenzy, sweat dripping off him and mixing with Austin’s precum, making a slick, furry surface for Austin to rub on. Jon’s cock spurted out another wad of precum, soaking Austin’s balls, and Austin returned the favor, leaking more between Jon’s furry pecs. “So FULL for you, Sir!” Jon bellowed, feeling bigger than ever before. “That’s right bull, always GROWING, turning into my prized muscle daddy BULLPUP, you want that don’t you, dad?” Austin said through gritted teeth, picking up speed as he desperately humped against the wall of beef in front of him, Jon’s round gut trying to push him backwards. “Yes Sir, gonna be the BIGGEST damn bullpup for you!” Jon groaned, his cock flaring up harder and longer as he approached climax. “Aww yeah, fuck yeah,” Austin panted, his hands squeezing and rubbing his stepdad’s impossibly enormous delts and arms. He leaned in and kissed Jon hard, both of them moaning and panting and growling as their tongues wrestled, both of them desperate for a taste of each other. They separated and Jon tensed his arms, flexing the round, hard biceps for his Sir. Austin squeezed harder, his comparatively small fingers hardly denting Jon’s massive muscles. Jon grinned. “Mmmm, even after all that food, son, you know what?” Jon rumbled. “What’s that pup?” Austin groaned. Jon’s pushed out his belly into full roundness, full hardness, squeezing Austin’s cock harder between his gut and Austin’s own muscular body. His gut groaned and gurgled loudly, like it was still empty. “I’m still HUNGRY!” Jon roared. Austin groaned and exploded, his cock spraying cum all over Jon’s chest, jets of it getting all over his bullpup’s huge beard. Jon’s cock followed suit, gushing cum against the underside of Austin’s throbbing balls, cum and sweat and fur mixing together in a moment of perfect release. They went on shooting for almost a minute, both of their bodies shaking and throbbing, cum dripping all over the carpet underneath them, smearing all over Jon’s huge body and Austin’s muscular legs and abs. Austin collapsed against his pup, utterly spent. Jon wrapped his enormous arms around his Sir and squeezed, securing his son against his cum and sweat-soaked body. “I love you so much, pup,” Austin whispered in Jon’s ear. “I love you too, Master,” Jon breathed and both of them felt a contentment that few on Earth ever get to experience.

Previous chapters: Chapter 1 Chapter 2 Chapter 3 Chapter 4 Chapter 5 Chapter 6 Chapter 7 Chapter 8 Chapter 9 Austin enjoys life with his growing, submissive stepdad. Jon lifts some weights in the backyard, then gets excited after his weigh-in and gets an intense blowjob from his Master. Chapter 10: Spring Break — Life With a Growing, Submissive Bull Pt1 The ground shook as Austin watched the beat-up old Ford F150 rise up into the air and crash back down again, bouncing on its shocks each time it hit the ground. The truck itself weighed somewhere around 2 tons, at least according to what Austin had looked up online when he bought it. Perfect weight to challenge the enormous man hefting it up and down like a medicine ball. Jon grunted as he picked up the truck again, lifted it over his head, and grinned down at his master. “Twenty!” Jon boomed proudly, straightening out his arms all the way, his enormous triceps and delts hard and flexing as he held the truck 12 feet off the ground, gripping the axles underneath. He wasn’t shaking or struggling at all, even 20 reps in; it was getting noticeably easier for him just in the last few days, Austin noted. He’d have to try to find another, heavier truck for Jon to lift with soon. The truck crashed down to the ground again, adding to the muddy divots in the grass of the backyard. Jon was soaked and dripping with sweat despite the cool spring Minnesota air, grunting and breathing heavily, clouds of vapor billowing from his beard-covered mouth. His quads shook as he walked around the truck to come closer to Austin, each one swelling out to the sides with round arcs of muscle. Each thigh rubbed against the other one roughly, the enormous bulge in his white Underarmour compression shorts bouncing as he did, the head of his huge cock plainly visible. The tight athletic boxer-briefs were the only thing he had on except for leather bicep straps, custom-made Underarmour football cleats, and long compression socks that were stretched thin over his massive calves. A wet spot spread over his bulge as he looked down at Austin and grinned. “How’s that, Sir? Bigger?” Jon rumbled, his voice unnaturally deep and loud. He planted the tip of his cleat on the grass, the spikes digging into the dirt, and flexed a calf muscle bigger than Austin’s thigh. The straining socks somehow made it look even bigger. He shook the meaty mass of his quads before flexing them, and they hardened into bulging slabs of muscle. His huge, round gut jiggled too, just looming above Austin’s face. “Do you think I’m growing?” the muscle bear boomed. Austin shook his head. Jon always asked questions like that even when the answer seemed obvious, but he knew it was because he craved the approval of his Sir. “Yes, bull, you’re bigger than ever!” “Oh, hehe, that’s good!” Jon said, a huge grin breaking out on his face. He reached up and stroked his dirty blonde beard, which stretched down into his pec cleavage, sticking to the sweaty expanse of his chest. Austin looked up at the giant above him; Jon had just passed 10 feet tall two days ago and was closing in on an even ton. “Looking easier for you, huh?” Austin said. He reached forward to rub his stepdad’s enormous thighs, running his hands through the sweaty, furry, hard expanse of muscle. Austin came up to Jon’s expansive gut, so his huge legs, barrel chest, and thick midsection were all in easy reach. His knuckles brushed against Jon’s bulge and the wet spot on his briefs grew as another spurt of precum leaked out. “Y-yes Sir, two tons is easy for a giant bull like me,” Jon groaned, trying to control his feelings. His cock throbbed and grew, the head of it poking out above his briefs and burping up more pre. It was very hard to stay focused when Master watched him lift weights. He rubbed his hands up and down his sweaty, furry torso, a mist of sweat rising into the cool spring air. “Good bull, that’s right,” Austin said. “And you’re gonna keep getting stronger. Show me your bench press,” Austin said. “Yes Sir!” Jon boomed, and he went back over to the truck. He laid down on the ground, getting dirt and brown grass over his expansive back, then reached one hand under the truck and pulled it over closer. With impossible strength, he hoisted the truck onto his chest, his pillowy pecs taking the impact of the tires and undercarriage with no problem. He gripped the axles and pressed, lifting 4000lbs of truck into the air like it was a warmup. The truck flew up and down, up and down, Jon grunting and sweating but hardly straining against the two-ton weight. “Light weight, Sir! I need more!” Jon grunted between reps as he lifted and lifted, flying past 25 reps with no sign of slowing down. “Gotta lift big to get big, that’s what you always say, Sir!” “That’s right bull, keep going until 100!” Austin said. He had to adjust his own package watching his giant muscle daddy lifting. His strength was beyond anything he had ever seen, unbelievable if he wasn’t witnessing it himself. Jon’s impossible, endless second puberty had only picked up steam since he had visited his dorm room just over a month ago and Austin had moved back in with Jon. Their total focus and dedication had only accelerated his uncanny growth. Jon threw the truck aside, crashing it onto its side as he roared past 100 reps. He scrambled to his feet with startling speed and energy, seemingly not tired at all despite being two hours into his second workout of the day. “Now, let’s do some cardio!” Austin held up a basketball. Jon instinctively turned and dropped into a three-point stance, facing the expansive backyard, his meaty ass in Austin’s face. “Go!” Austin yelled as he threw the ball as hard as he could. Jon grunted and bounded after the ball, his custom-made oversized cleats tearing more divots into the once-pristine grass of the backyard. Jon ran, the huge, rumbling footsteps of the massive brute eating up space surprisingly fast. His heavy chain necklace jingled as he ran. The ball sailed a long ways, and Jon was so focused on it that he didn’t notice the thin birch tree that stood in his way until he shouldered into it; the tree exploded into splinters and fell over as Jon plowed into it. Seeing his target, Jon lunged onto the ball, squashing it under his enormous weight until it popped open with a crack. Rising quickly, he ran back to Austin just as fast, ball tucked into the crook of his arm, pressed between his enormous bicep and meaty chest. He nearly barreled into Austin before skidding to a halt, tearing up more grass. He beamed down at his master, grunting and breathing heavy. “Another one?” Austin said, looking up at his giant stepdad with a disapproving look. “Throw it on the pile,” Austin said, gesturing to the pile of other broken balls and fetching toys. “Heh, sorry Sir, I got excited,” Jon said as he adjusted the tight leather straps digging into his biceps. Austin had bought the custom, adjustable straps at his local fetish gear shop a couple weeks ago with the intention that they would last for months. They weren’t on the loosest setting of 36” yet, but as Austin eyed Jon’s throbbing, hard biceps and heard the leather groaning, he knew they wouldn’t last long. “That’s fine, pup, I love your enthusiasm!” Austin said, getting another ball. “Ooh ooh, can I do another one? Please?” Jon pleaded, bouncing up and down excitedly as he inched closer to his Sir. Austin knew that Jon could take the ball from him whenever he wanted, but he wanted to please his master and run hard for him. Sprinting made his legs and lungs stronger for master. “Ready?” Austin teased, and Jon dropped into a three-point stance again, like a giant football player. “All the way down this time,” Austin said, and Jon dropped onto his stomach with a thump, the nearly plants and trees shaking from the impact. “Go!” Grass ripped up from the ground as Jon exploded off the ground with terrifying power and he launched himself after the ball again. They kept at this for half an hour, Austin working Jon until he was a sweaty mess, the dense fur covering every inch of body soaked and curling with sweat, dirt covering his cleats and calves, his compression shorts soaked through. When Austin finally said that was enough, Jon was panting and tuckered out. “Bring it in, pup, such good work,” Austin said. “Here you go,” he said and held up a gallon-sized jug filled with brown liquid. “Hrrrrmmmmmph just what I need!” Jon grunted as he grabbed the jug, his fingers easily wrapping all the way around it, and started chugging the thick, viscous shake. Austin marveled at how quickly the big man could consume, watching his Adam’s apple bob up and down, listening to the gurgling, groaning, throbbing sound of Jon chugging the 4000 calorie shake. Austin looked up at Jon’s round gut noticeably expanding as it filled up with protein shake until the arc of it brushed against Austin’s forehead. In seconds, the jug was empty. “Ahhhh, that hit the spot, Master!” Jon sighed contentedly as he rubbed his belly, bumping Austin backwards as he did. “More?” Jon asked eagerly as he looked down as his diminutive master, his cock throbbing as he did. “Later, bull. First it’s time for our daily weigh-in!” Austin said and he gestured over to the scale. Jon knew the drill. They followed the same routine every day, lifting and feeding times regimented and organized, weigh-ins and measurements regular and tracked by Austin’s diligent eye, calories and nutrition and exercise optimized for maximum growth. They had an industrial-size scale that was meant for livestock set up on the back deck, which was a couple feet elevated up off the ground. Jon lumbered over, the deck straining under his mass as he walked across, his ass shaking and jiggling up and down as he waddled. Suddenly his right foot broke through the wooden decking and he fell forward and down a foot or two. “Uh oh! Sorry Sir. Rrrruuuuffff, grrrufff!” Jon grunted as he ripped his foot up through the decking, tearing up more of the deck as he kept walking over to the scale. Casual, accidental destruction was becoming more and more common with Jon as he grew beyond normal human scale. The scrapes and holes that dotted the ceilings and the cracked, partly-destroyed doorways in the house were testament to that. Jon stepped on the scale until the number evened out. “1824 pounds! Great job, bull. Boy, you’re getting so big, aren’t you?” Austin said, praising his prized bullpup as he rubbed Jon’s huge, round ass. “Yeah, always bigger, always more, that’s what you always say, Sir,” Jon grunted. “I gotta keep growing, right?” Jon stepped off the scale and turned to face his Sir, looking down at him from over the round hills of his pecs and gut. Sweat dripped down off his nose and nipples, some of it splashing on Austin. “That’s right, pup, always bigger, always more!” Austin repeated. It was the mantra that Austin had come up with since he had moved in to help keep them both focused and motivated on their shared goal. Every aspect of their lives was focused on one thing: to grow Jon as big and strong as they possibly could. “Yeah,” Jon breathed, steam puffing into the air. He looked up into the grey sky and raised his arms up into a flex, steam and heat from his sweaty pits radiating off him. “MORE!” His arms were spread wide, biceps flexed, his forearms spread out at a 45 degree angle, making the biceps look extra thick. Jon’s bulge throbbed and swelled in his Underarmour until they stretched the white material close to bursting. The cock head surged and poked out at the top as if it had a mind of its own. Jon grunted involuntarily as a glob of precum gushed out and splashed onto the grass in front of Austin. “You worked so hard today, bull,” Austin said, looking up at his submissive daddy. They locked eyes, staring intensely, each of them breathing heavily, cocks throbbing. “Let me help you with that.” Austin stepped forward and tugged at the hem of Jon’s shorts until he freed the rest of the meaty, Pringles-can sized cock from its confines. The heady, funky smell of Jon’s crotch and balls wafted into the air, steam rising from his loins. Austin huffed in the smell, sending tingles of excitement down his spine. He was at the perfect height now to suck Jon’s dick while standing. He opened wide and gobbled up as much of his pup’s cock as he could. “Ohhhhhhhnnggggg Sirrrrrr,” Jon groaned, a bassy rumble filling the air, deep enough to rattle Austin’s ribcage. “Rrrrrrruuuuuffffff,” he moaned unintelligibly. Austin pushed deeper, the massive cock head filling every inch of his mouth, jamming it until it scraped the back of his throat. He could only swallow up about half of its length now and barely wrap his lips around it. He was well-practiced with it at this point and didn’t gag, though he knew that he wouldn’t be able to take such a huge cock for too much longer as Jon grew more and more. “Yeahhhhhhh, gotta grow more for my Sirrrrrr,” Jon purred. He reached down, past the love handles of his huge gut, and wrapped his hands around Austin’s chest, easily lifting him into the air. He brought Austin up to his bearded mouth and kissed him roughly, his tongue plunging into Austin’s mouth aggressively. “Morrrrrrre,” he groaned as he walked over to the wall of the house, protein breath washing over Austin as Jon breathed heavily. Jon plopped Austin back down to the ground and brandished his cock like a club, thumping Austin in the face with the swollen, throbbing member. “Harrrrrder,” Jon groaned, his thoughts focused only on pleasure. Jon slammed his weight forward into Austin’s awaiting mouth. Jon looked down and couldn’t see anything past the expanse of his enormous furry muscles and round power gut. He could feel Austin sucking and choking and gagging on his cock but couldn’t see him at all. Jon was just too big. “So big. The biggest!” Jon moaned, humping his enormous body against Austin. He leaned forward onto the house, bracing against the wall with his thick, veiny, hairy forearms, leaving smears of sweat against the cold siding. Austin could only groan and brace himself against the huge thighs that surrounded him. He pressed his arms against the huge, heavy gut that pressed down on him, but it was futile; it was simply too heavy. Austin felt himself squeeze harder against the wall of the house as Jon humped harder and faster, picking up steam. “Always bigger, always more for you, Sir!” Jon groaned as he plowed his master’s tight mouth. His Sir had given him purpose and value and meaning, all he ever needed. The thought of growing even bigger, of swelling beyond the impossible size he had already reached, of making his master even happier and even more proud of him, filled him with euphoria. His cock throbbed harder and more precum oozed down Austin’s throat. “You like how strong I am now, Sir?” Jon asked, an edge of pleading and begging in his sonorous voice. Austin grunted and groaned, his throat choking on the massive cock as he tried to respond. “You want me to keep growing bigger, Sir?” Jon groaned, his deep voice straining as his cock throbbed harder and harder. Austin moaned as loudly as he could, needing his pup’s cum. “I’ll do anything for you Sir, I’m gonna be the very biggest for you, Sir, all for you Sirrrrrrrrahahhhhhhhhh!!!!” Jon roared as his cock exploded, his huge balls tensing and throbbing as jets of cum sprayed directly down Austin’s throat, feeding his master his potent bull cream. Austin gulped furiously, trying to cope with the intense volume of cum flowing into him, but it was no use. Spurts of cum dribbled from his mouth and onto his beard, mixing together with Jon’s sweat in his sweaty, bushy pubes. Jon leaned into Austin harder until every drop was drained, grunting and groaning loudly. Jon arched his neck and back and sighed contently, a plume of steam rising into the air, satiated for now. He was proud to give his master a thick meal of bull cum. Jon stepped back and Austin coughed and sputtered, cum drooling down his mouth and covering his beard and parts of his shirt. He grinned up at his pup. “Good work, bull, wow that was some load! You were really worked up, huh?” “Heh, yeah, grruuuufff, love humping my Sir’s face I guess,” Jon said, raising his arm up and scratching the back of his head sheepishly. As he did, his enormous tummy rumbled loudly, demanding more food. “Sounds like it’s time to eat!” Austin said, staring up at his big pup. Jon rubbed his round belly and licked his lips in anticipation. “Sure is, Sir. I’m STARVING!” Jon rumbled as his gut growled again, louder and longer.

Previous chapters: Chapter 1 Chapter 2 Chapter 3 Chapter 4 Chapter 5 Chapter 6 Jon makes a surprise visit to see Austin on campus. The two celebrate Valentine's Day together the best way a pup and his sir know how. Chapter 7: Valentine’s Day Austin leaned back from his textbook and yawned, beleaguered from another long evening of studying. He knew he less than two quarters left of college, but he had to study hard for midterms to keep on track to graduate. His mind was constantly occupied with planning his life after college, and especially with the football season over, he had little to look forward to on campus. He lived in a small single room in a relatively older building on campus, a strange choice for a senior who had more than enough resources to move somewhere nicer, but Austin appreciated the spartan accommodations; it helped him stay on track with his goals. Besides, he wasn’t around much anyway, usually either at the gym, at class, at the cafeteria, or at the library. Austin heard heavy footsteps thump outside of his room, then suddenly a loud knock thumped on his door three times. He jumped a little, alarmed and taken aback; no one ever visited him, especially not at 10pm on a Friday night. “Hello?” he asked as he got up and went over to his door, unlocking it and then pulling it open. There in front of him was a wall of beefy muscle, barely contained by a comically tight shirt with the mascot logo of the college stretched to absurdity. Austin’s eyes traveled up from the exposed, round, cobblestone gut, up to the tight grey fabric that strained across the widest chest he had ever seen, up to the shoulders that protruded from the torn-off sleeves, up to the grinning, bearded face that stared down at him from the ceiling of the hallway. “Sir!” Jon boomed as he saw Austin. “Happy Valentine’s Day!” He reached his massive paws forward to grab Austin, only for Jon’s forehead to crack against the metal doorframe of Austin’s room. The metal dented and a chunk of plaster fell onto the floor. “Ouch, dammit, happening more and more lately,” Jon grumbled as Austin stepped backwards into his room. “Pup, what are you doing here!? It’s… how…,” Austin said, breathless and confused and excited. Jon ducked down and turned sideways, reached his massive arms through the entrance, and squeezed his way into Austin’s room, his chest and ass and gut scraping against the doorframe until he suddenly popped into the room, a wave of heat and musky BO stink rushing inside as he entered. His head scraped against the 8 foot ceiling as he stood to his full, unbelievable height. He took a deep breath and sighed when he finally was inside, shutting the door harder than he needed to as he grinned down – way down! – at his smaller stepson. “Surprise! I just had to come see you, it’s been WEEKS,” Jon said as he stepped closer to his little master. “I’m so excited to see you!” Jon said as he bent down, reached forward, and gathered Austin up into the biggest bear hug in history, effortlessly lifting the 230lb college jock off his feet and squeezing him tight. “Mmmmm my little Sir, you’re even smaller than you were at Christmas, hehe,” Jon grunted, his voice deeper and more resonant than Austin remembered. “P-pup, put me – uunnnhhhgggg – down!” Austin croaked as the breath was squeezed out his lungs and he felt his back pop. “Heh, oops, sorry Sir,” Jon said as he put Austin down. He still kept close though, crowding Austin’s space and pinning him up against the desk. “I was just so excited to see you, and even though you didn’t tell me to, I had to come see you, Sir,” Jon said bashfully as he rubbed up against Austin, his throbbing bulge pulsing against Austin’s chest. Austin could easily feel Jon’s cock through the thin compression shorts that served as Jon’s pants; he was sure it was the only thing left he could find that fit. “Well, pup, it’s amazing to see you... and feel you,” Austin said as he brought his hands up to rub his stepdad’s incredibly huge belly, arms, and chest. “Yeah?” Jon said, pushing Austin harder into the desk. “Am I bigger?” “Uh, yeah bull, you’re WAY bigger, like holy cow!” Austin said, laughing at the absurdity of Jon’s question. “Your head is to the ceiling and you’ve gotta be twice as wide as me now. So much size…” Austin said as he rubbed harder, reaching under the too-tight shirt to rub his pup’s furry chest. Austin realized this was the same 4XL that he gave his dad at Christmas; it had been tight then, but now it clearly didn’t fit. “I wanna be huge,” Jon grunted dreamily as Austin rubbed his meaty nips. “I follow your routine and schedule every day to the letter, Sir,” the massive weightlifter groaned. “Feels so good to follow your orders, Sir, need to make master happy,” he sighed and his massive bulge drooled through his compression shorts and onto Austin’s tank top. “I need more, Sir, gotta get huge for you.” “Good bullpup, that’s good,” Austin whispered, pushing back against his stepdad; Jon didn’t budge. “How big are you now, pup?” Austin knew from the daily updates he had his dad send him now, but he wanted to hear it anyway. “Just passed 8 feet tall on Wednesday,” Jon grunted as he rutted against his master, pushing the desk harder against the wall. “Up to, uunnnfff, 900 pounds,” Jon said as he raised his arms up and pressed his palms against the ceiling and flexed, his biceps exploding with size, his hairy pits reeking of man musk, his shirt riding up and exposing his round, furry gut. “All for you, Sir,” Jon rumbled as he loomed over his smaller stepson. “Almost four times your weight now, Sir!” “Good, bull, good. But you’re very naughty for coming here! I didn’t tell you to come see me,” Austin said with a hint of disapproval in his voice, reaching up and tugging on Jon’s heavy lock and chain that wrapped around his thick neck. Jon looked down at his little Sir and his eyes welled with tears. “S-Sir, I just hadn’t seen you and I wanted, uh, I needed…” he whimpered, his chin quivering. “Well, I’m not sure pup deserves to see me since he came here without my permission,” Austin said, tugging on the chain harder and pulling Jon down until they were face to face, Jon’s weathered, slightly wrinkled forehead bumping against Austin’s smooth, young skin. “Did I tell you to drive here? Aren’t you supposed to be having your third workout right now before your late-night protein binge?” Jon looked down, away from his master’s intense gaze. “N-no Sir, I mean yes I should be doing that now Sir,” he said, in as small and sad of a voice as an 8 foot tall, 42-year-old hulk could manage. He dropped his arms and brought his hands down, pressing his pointer fingers against each other nervously. “I just—“ “And what did I say about doing stuff like this without telling me first?” Austin said. They were both breathing hard against each other, their lips close, Jon’s breath smelling like protein shakes and fast food. Jon gulped and stuttered. “T-to always tell you first,” Jon said timidly, his bassy voice quivering. “I just, Sir, I—“ Jon started, then wrapped his enormous arms around Austin, engulfing him completely. “I just love you so much I had to see you, and it’s Valentine’s, and I—” he gushed, choking up a little. “Awww, there there pup, that’s a good boy. You just missed your Sir that much, huh?” Austin said, letting his stepdad rest his heavy head against his shoulder as they embraced. Jon nodded heavily, his grey-blonde beard tickling against Austin’s neck as he did. “Bull gets real lonely without his Sir to take care of him, doesn’t he?” Austin rubbed his hand through Jon’s tightly trimmed mohawk and against his thick neck rolls. *Sniff* “Y-yeah!” Jon sighed, his warm breath blowing against Austin’s ear. He shuddered as he took in a big breath. “I NEED you, Sir!” Austin could feel Jon’s enormous cock press harder against his firm abs. “Aww pup, I can’t say no to you! My big, sweet bull. I love you too.” Jon sighed and shuddered as he heard those words. He squeezed his enormous, steel-hard arms against Austin even harder and his cock inched higher and longer against Austin’s torso. He rubbed his baseball glove-sized paws against Austin’s back in wide, firm circles, feeling the lean, taut muscle of his master. “And hey bud, I missed you too. It’s been hard without you and I think about you all the time,” Austin said. “You know what I think you need, pup?” Austin said as he separated from Jon and they stood apart for a moment, both of them eyeing each other up and down, both of them breathing heavy and starting to sweat. “What’s that, Sir?” Jon said as he adjusted his leaking bulge. “I think you need your Sir’s seed inside to you to remind you who’s in charge,” Austin growled and then hefted his own weighty package. Jon huffed and and sighed at those words, and his cock throbbed anew. “Grrruuuff, yes Sir! That’s just what I need!” Jon grunted desperately. He reached up to the hem of his shirt and tugged hard, and the shirt ripped clean down the middle, revealing his enormous, wide, hairy chest and round, turtleshell gut. His cock tented his compression shorts obscenely. Austin stepped closer to his stepdad and reached up to rub the enormous pecs looming over him. “My god, pup, you’re getting absolutely gigantic, aren’t you?” Austin said, flicking Jon’s nips. Jon’s pecs twitched and bounced, heaving up and down as Austin played with them, thick and meaty then hard when he flexed them, covered in a dense layer of blonde and grey fur. “Ruufff, unnnfff!” Jon grunted, pleasure and submissiveness making it difficult to speak. “That’s — rrrfff! — right, Sir! All for you, Sir!” Jon grunted as he tensed and bounced his enormous pecs. “I bet this big chest is bigger around than I am tall now, huh?” Austin said in a low, intense voice, his cock twitching in the basketball shorts he used as pajamas. “Big bull freak growing every day, huh?” “Yeah!” Jon said, his chest heaving up and down. “Yeah!!” he boomed and lifted his massive arms up into a flex. His fists crunched against the ceiling, leaving dents and sending plaster to the floor, but Jon didn’t even flinch. His arms surged to full size, bigger than Jon’s head, bigger around than Austin’s thighs, round hard bicep peaks throbbing, watermelon-sized delts spreading wider, thick traps surging up like a mountain range. “So fuckin’ BIG, yeah!” Austin growled as he reached up to feel Jon’s enormous arms. He could barely reach them. He couldn’t even get his hands halfway around them; he clutched at them hungrily, sliding his hands over the sweat-slick peaks and down into the damp, furry pits. Jon grinned with pride. “Turn around and show me that big ass, bull,” Austin commanded, his voice deep and authoritative. He huffed Jon’s pit stink on his fingers and his cock twitched. Jon obeyed, his cock throbbing in acknowledgement. “Been working them hard for you Sir,” Jon rumbled. He turned around, bent over, and started wriggling out of his compression shorts. “What do you think? Am I bigger?” Jon’s enormous round glutes spread apart just wide enough for Austin to see Jon’s tight, furry hole tensing in anticipation. Austin grabbed the compression shorts and pulled them down lower, revealing Jon’s freaky thick hamstrings, which twitched as Jon shifted his weight. His ass was covered in dirty blonde fur; hard, thick muscle jiggled and bulged as Jon bent down further. “Oh yeah, bull, much bigger, so massive. You’ve done so well, pup. You’ve been growing so much these last few weeks huh?” Austin said as he jiggled Jon’s bubble butt with one hand and reached for the lube next to his nightstand with the other. “Yes Sir!” Jon boomed. He put his hands on his hips and spread his back and shoulders as wide as he could, his incredible traps and lats on display, bulging and huge. His shoulders were wider than the big TV Austin had in his dorm room, blocking out the entire frame. His lats spread out so wide they pushed his arms out even farther, and his traps surged into mountains of muscle; he had no neck to speak of anymore. “Growing faster than ever! Bigger for you, Sir! I still need MORE though, gotta get HU—uuuhhhhgggg ohhhhhh Sir!” Jon moaned as Austin’s fingers probed his tight, muscular hole. “Yeah pup, you like that? You like your Sir’s fingers loosening up that tight hole, don’t you?” Austin growled as he entered his stepdad, leaning against Jon’s massive furry back and rubbing his muscles. “Rruuuuurrrfff, uhhhhggg, rooooooffff!!!” Jon rumbled. He started huffing and panting as Austin got him ready for the main event. “Such a good bull pup, so proud of my pup. I can’t stay mad at you, pup, not when you keep growing big like this. You’re the biggest man on the damn planet now, you know that?” Austin said, pumping him up and loosening his muscular hole. “Ruffff!!” Jon grunted and flexed his big muscles. “Gotta grow big for you, Sir! That’s all that matters!” “That’s right,” Austin said, slipping out of his shorts and revealing his own 8” cock. He rubbed it against Jon’s furry hole, smearing sticky precum that mixed into Jon’s fur. “Such a good, obedient bull! Now are you ready for your son to breed you, dad?” Jon spread his legs wider, his hole begging to be pounded, and moaned unintelligibly in anticipation. Austin had to get on his tip-toes for his cock to line up with Jon’s ass. The curly blonde fur felt incredible against his raging hard-on, and Austin leaned his 230lbs against his musclebear stepdad, his bulbous cock head penetrating Jon’s tight hole. “GGGGRRRRAAAAHHHHHH!!” Jon grunted as Austin entered him. “BREED ME, SIR! BREED YOUR BULL!” Jon bellowed as Austin pressed into him balls deep. “Fuck yeah, dad, you’re so fuckin’ tight,” Austin sighed as he reached up and grabbed on to Jon’s enormous traps. Jon was so much bigger than Austin that he could just barely reach all the way up. Austin got into a rhythm quickly, pushing deep and stretching Jon out as the older man groaned and grunted in time with Austin’s thrusts. He started slow, then started pushing faster as he found his groove. Jon’s cock grew even harder as he got fucked, the wrist-thick shaft throbbing with veins, smearing precum all over Austin’s laptop and desk, pools of it leaking onto Austin’s papers. “Fuck, bull, I can’t believe how big you’re getting,” Austin panted as he pounded his pup. “Grrruuf, uuurrrrhhhggg, aahahhhhh!!” Jon grunted, sweat splashing down onto Austin’s desk. “You’re growing, unnnggg, so goddamn fast, bull, unnfff, it’s just unreal!” Austin gasped, taking in the full size and width of the man in front of him. Jon’s triceps bulged with thick muscle as he braced himself against the desk. “No one has grown so big so fast, dad, ever!” “Ruuuuooooofffff fuck yeah, all for you, son!” Jon boomed as he pushed his weight back against Austin, causing his cock to punch in even deeper but also making Austin stumble back a bit. Austin backed up, taking Jon with him, and looked across the room to the full-length mirror on the back of his door. “Look at us, bull! Football jock son breeding my big bull dad, just like you needed, huh?” Jon looked over at the reflection and groaned, his own massive cock throbbing harder and spurting pre onto the rug. “Arrroooooffff, breed me, son, give me your load, daddy bull needs it!” Jon grunted, guttural, primal, out of control. He looked in the mirror again, marveling at the size difference between them, flexing his bicep in the mirror and watching it swell, fixating on his own massive bulk. He then looked at the hot jock stud thrusting into his huge ass, the smaller man half his age, Austin’s face grimacing in concentration and pleasure, sweat glistening on his arms and chest. Jon pushed back harder against Austin, causing the big football jock to stumble again, Jon’s bulk overwhelming his son. “Fuck, bull, you’re so goddamn heavy, pushing against my cock so hard!” Austin said as he realized he was backed against his bed. “Rrrruuuugggh, ruuuufff, mmmmrrrrooooo!” Jon bellowed as he pushed harder against Austin’s cock, needing it deeper and harder, craving his master’s cum, his own cock throbbing harder and leaking all over the place. Austin lost his balance and sat down on his bed, and his massive stepdad crashed down on top of him, pressing his enormous ass and 900lbs of musclebear mass down onto Austin. The pathetically small twin bed cracked and collapsed, causing both men to crash down to the floor. Austin’s cock pressed even deeper into Jon’s tight hole, and the big man roared with pleasure. Austin grunted and gasped as Jon’s full weight bore down on him, pressing his cock in deeper and harder, his dad threatening to crush him under his impossibly huge body. “Unnnffff, dad, you’re so… so fuckin… BIG!” Austin grunted. “I’m gonna… getting so close to… UNNGGH!” “FUCK yeah Sir, give me your load!, RRRRUUUHHHHRRR” Jon boomed as he bounced up and down on Austin’s big cock, slamming his prostate against Austin’s meaty cock head over and over, nearly half a ton of muscle daddy crushing down on Austin’s cock. Jon’s cock pumped up thicker and throbbed as he got closer to shooting his own load, and he grabbed onto it with both hands and stroked himself desperately. “Unnnnggg, fuck yeah bull, take my seed, fuuuuucccckkk!” Austin roared as he exploded inside of Jon, filling the massive muscle bull with hot jock cum. Both men grunted and groaned as they both shot epic loads, Jon’s cock exploding all over Austin’s dorm, filling the room with the tang of pungent bull cum and musky BO. Their grunts and moans could be heard throughout the building. When they were done, Jon lifted himself off of Austin, his smaller stepson groaning and gasping as Jon’s 900 pounds stopped crushing him. Jon turned around and towered over his Sir, cum dripping down onto the bed and floor; he rubbed some of it into the fur of his chest and gut and tasted the cream that was dripping off his fingers. Austin panted for a moment, then looked up at Jon with a laugh. “Mmm, you really needed my load, didn’t you bull?” Jon licked his fingers and nodded. “Mmmm hmm Sir, I did.” “Heh, I could tell, you knocked me over, you were so eager for it,” Austin said. “Now you have your Sir’s seed inside of you, as it should be,” he said. Jon reached down and offered his Sir a hand, and Austin took it. Jon lifted him up so hard and fast that Austin popped up off his feet and fell against Jon’s massive, cum-covered chest; Jon caught him in mid-air and supported him, his huge hands cupping Austin’s bubble butt. Their cocks pressed against each other as they proceeded to make out in the afterglow, their cum mixing together and smearing against their sweaty bodies. “Yes Sir, feels good to have your warm seed inside me, I needed it so badly,” Jon said, his cock already chubbing up again thinking about it. “I feel complete now, Sir, with you here in my big arms,” he purred as he rubbed his long blonde beard against Austin’s shorter, darker beard. “That’s my good daddy bull,” Austin whispered to him as Jon held him effortlessly in the middle of the room, sticky and sweaty and utterly content. "Happy Valentine's Day," he said, and they kissed passionately.

Previous chapters: Chapter 1 Chapter 2 Chapter 3 Chapter 4 Chapter 5 Chapter 6 Chapter 7 Jon and Austin enjoy a day on campus together, availing themselves of the gym, wrestling practice room, and cafeteria. Jon woke up and realized there was a weight pressing down on top of his massive chest. He breathed in deep and saw Austin, his beautiful stepson Sir, whose body rose and fell with every one of Jon’s breaths. He breathed in deep again through his nose, breathing in the scent of his Sir that filled the room, mixed in with his own tangy musk and the smell of dried cum. His little Sir had slept on top of him all night, using Jon like a big muscly mattress. Jon didn’t fit on the absurdly small twin-sized mattress underneath him; his legs hung off the end of the bed from the knees down, and his shoulders and arms spilled over the sides and onto the floor. It hadn’t been the most comfortable sleep, but with Austin in his arms, it was the best sleep in the world. Jon sighed contently, the warm wind of his nose causing Austin to stir and awaken as well. “Good morning, Sir,” Jon said softly. He lifted his arms and wrapped them around Austin, squeezing him tightly against his bulk. “It feels so good waking up with you in my arms,” Jon sighed. “Mmm, same to you, pup,” Austin said groggily. He propped himself up by pressing his hands against Jon’s pillow-sized pecs and pressed his hard cock against his stepdad’s round belly. “Last night was so much fun!” Austin said with a smirk. “I’m glad you liked it, Sir,” Jon said. “I can still feel your loads inside me, filling me with strength,” Jon growled. Austin felt something smack him from behind and realized it was Jon’s enormous cock slapping his back. It twitched and swelled bigger, thicker, longer, smearing precum along Austin’s spine as it grew and grew to full hardness. “Well well, someone is excited to wake up with his master on top of him, aren’t they?” Austin said. He leaned back against Jon, rubbing his furry crack against his dad’s hard cock. “Unf, Sir, you just make me feel… rrruuuuuhffff,” Jon groaned as his cock twitched and leaked uncontrollably. “Gotta cum real bad, Sir,” he rumbled. “Well pup, we can’t yet. We have a big day ahead of us,” Austin said. “No loads until I say so, got it?” Austin said in jokingly sing-songy voice, like one would use with a child. Jon groaned and stretched, arching his back and lifting Austin higher up into the air. “Uhhhgggg but Sir, I need it so bad!” Jon whined and he reached down to squeeze his cock against Austin’s back. The massive tool reached halfway up Austin’s back, ooze leaking all over Austin’s spine. “I know, big bull, but right now you need to eat! Get up and carry me over to the fridge!” Austin said. Jon, of course, did as he was told, effortlessly lifting his 230lb Sir up as he rose to his towering 8 feet tall height. His head bumped into the ceiling and he chuckled, amused by his own enormity. They were both naked, their bodies rubbing against each other. Jon’s cavernous stomach groaned and gurgled loudly. “Mmm, I AM pretty hungry, Sir,” Jon rumbled as he stomped over to his stepson’s dorm kitchenette, the entire room shaking with each step. “Well I’ve got just the thing for you,” Austin said as Jon put him down. Austin put together the biggest, thickest, most calorie-dense shake Jon had ever seen, filling it with gainer shake powder, bananas, oats, olive oil, honey, whole milk, preworkout, and more. By the time he was done, it was a brown slurry that filled the blender to the brim. “Drink, now, every drop, chug it,” Austin commanded. The massive bear palmed the blender container in one huge hand and lifted it to his maw. He started gulping it down the viscous sludge shockingly fast, astounding Austin with the aggressive, relentless speed he consumed it, his Adam’s Apple bobbing up and down fast. In seconds, he was done, a couple drops dribbling down into his thick beard. Jon gasped for air when he was done and took a deep breath. His belch shook the window panes with its ferocity and depth. “MORE!” he boomed as he handed the blender back to Austin. This continued several more times until Jon had his fill, each time his gut swelling out rounder and bigger and heavier. Austin encouraged him by rubbing his massive belly and reminding him how much bigger all these calories were going to make him. Jon kept asking for more after each shake, his hunger seemingly insatiable. By the time Jon was done, he had already put away around 10000 calories and hundreds of grams of protein. “Now, pup, I have what you’re going to wear today,” Austin said as he dug around in his closet. “I was going to give this to you as a present, but since you need a shirt… Such a good obedient pup needs to let everyone know what he is!” Austin said as he handed Jon his new shirt. Jon unfolded it. It was an absurdly small, tan-colored crop-top with one word emblazoned in rainbow lettering on the front: BEEF. Jon grinned and his eyes lit up. “I am Beef!” he bellowed. He bent over and Austin helped him into the shirt, wriggling and shimmying to get the tight garment to stretch over his enormous bulk. He did the same with the black jock strap and white Under Armour compression shorts, then put on his extra wide Otomix. Jon looked down, past his beard which merged with his furry chest, and looked at this new label, BEEF, and grinned. He flexed his chest, the surging pec meat making his shirt stretch taut across his shoulders and between his pecs. His round, furry gut was totally exposed, and his massive bulge and huge ass stood out prominently thanks to the jock strap. “Today you are no longer bull or pup or Jon, you are Beef. Mine to command and obey,” Austin said with a smirk. “Your goal, Beef, is to pack on as much meat onto your giant frame as possible today, got it?” “YES SIR!” Beef rumbled and stood at attention, his bulge twitching, his shoulders round and wide. “Then, if you are good, we will come home and we will take care of his,” Austin said as he cupped Beef’s huge package and fondled it up and down. Beef shivered and grunted, and his cock throbbed in his jock. “Finally, I’m going to lead you to the gym using this,” Austin said, and he pulled out a leash. “Lean down,” he commanded, and Beef obeyed. Austin clicked the leash harness through one of the links of Beef’s heavy chain necklace. “Everyone on campus will know that you are mine. You’re going to be a good boy and do everything I say, right Beef?” Austin said. Beef nodded eagerly, his eyebrows arching with an expression that made it clear he was desperate to please his master. “Good boy,” Austin said as he tugged on the leash, Beef’s thick neck hardly budging against the firm leash. “Now, to the gym!” Austin said, and he led Beef out of the door. As they walked across campus, other students gawked, some laughing or pointing, others giving them a wide berth, while others stared and adjusted their crotches. Beef obediently followed his master, waddling across campus with heavy, thudding strides. His huge thighs rubbed against each other as he walked, and his belly swayed and jiggled, uncovered by the tight crop-top. Austin led the way, occasionally tugging at Beef’s leash and grinning at people gawking at them. Despite the frosty February temperatures, Beef wasn’t cold at all, steam rising off of his bull neck and wide shoulders. In fact, by the time they reached the gym he was already damp with sweat. His collar and leash jingled as they entered the building and went to the front desk of the gym. “I need a parent guest pass for my stepdad here,” Austin said to the desk clerk, gesturing to the enormous, bulky man next to him. Beef grinned broadly at the clerk, his face blushing bright red, his intense blue eyes sparkling. The clerk stared at him, slack-jawed, not knowing how to process the giant man in a comically tight crop-top attached to a dog leash. Beef took a deep breath, his chest expanding bigger and wider, and he flexed his pecs. “WOOF, RRUUUFFF!! Ready to LIFT!” he boomed down at the clerk, causing the underclassmen to flinch and reach for a day pass. Austin filled it out for Beef, and the two of them strode into the gym, heading for the squat rack. It was leg day, but Austin had Beef do a little bit of everything so he got a nice pump and got a good sweat going. Austin let Beef off his leash as they started to lift, and Beef nuzzled his chest against Austin’s face in appreciation. It was hard to find enough weight to challenge Beef, and Austin had to get creative. Beef had grown even stronger than Austin thought, and in trying to max out weights to challenge him, they used nearly every plate available. Austin tried standing on stacks of weights on the cable machine to create enough resistance for Beef, tried using bands and chains to add resistance, and did higher reps than he would normally think of, but it was rarely enough. Beef could easily curl hundreds of pounds, squat and deadlift double his weight, and did leg press with as many 100s and 45s as they could fit on the stack. He was tireless, relentless, and hardly needed any pauses between sets. Once Austin told him to do something, Beef did so with perfect form, ferocious intensity, and terrifying power. He panted and huffed and puffed but never complained, never slowed down, and looked absolutely content and in his element. Puddles of sweat followed them wherever they went, drops of it dripping off Beef’s face, arms, and shoulders, trickling down over his round gut and tree trunk-thick legs, soaked like he was caught in a rainstorm. Austin kept him fed with a bright-pink drink, a mix of powders and supplements that made Beef feel electric and focused and wired, the pump bloating his body up bigger and thicker than ever. Austin was shameless in touching and rubbing Beef’s big body as they lifted, groping his biceps and meaty ass as he lifted, Beef’s focus never fading, the only indication that he noticed coming from the enormous hard-ons that sprung up whenever Austin touched him. Beef grunted loudly with each rep, his resonant voice and massive weights booming in the open gym space, scaring off many of the usual early-morning crowd. He stared intensely as his own reflection in the mirror or at Austin, unblinking, locked in. After 3 hours straight of lifting, Beef stepped up closer to Austin and looked down at him from his 8 foot vantage. His massive gut groaned louder than Austin had ever heard it. “Sir, I’m hungry,” Beef rumbled, reaching down to rub his belly in a wide circle, sweat dripping off his hand in sheets as he did. His crop top was soaked, now a darker shade of tan, and Austin could see the straps and pouch of Beef’s jock strap through the tight compression shorts. “Need to fuel these muscles, Sir. When’s lunch?” Austin looked Beef over. His thighs and calves bulged with a massive pump, and his chest, arms, and shoulders were ruddy and swollen. Beef reached up and ran a hand through his mohawk, a spray of sweat misting off his hair and down onto Austin. “Soon, big boy. You’ve worked SO hard this morning, and now it’s time to eat. But first let’s go to the bathroom,” Austin said. He reached up and clasped Beef’s leash back on, and Beef moaned with pleasure as it locked around his heavy chain necklace. Austin led Beef back into the locker room, jerking his leash to get him to follow. Beef’s enormously wide shoulders took up the full breadth of the hallways, causing other gym goers to retreat. Beef and Austin made their way to the bathroom and went into the handicap stall. “Alright Beef, go ahead and relieve yourself,” Austin said. Beef dropped trou, his massive hose spilling out of his jock pouch, heavy balls emitting an intense musk. “Ahhhhhhh,” Beef groaned as a thick stream of piss started filling up the bowl. “Mmmm, such a big boy,” Austin said as he rubbed Beef’s thick glutes. “Such a good pump today, Beef, you worked hard,” Austin purred. Beef finished, bouncing his chubbed-up cock to get any stray drops, then stuffed his package back into the jock strap. “Thank you, Sir!” he boomed. Beef realized he could easily see over the bathroom stall partitions; he could just see himself reflected in the mirrors looming over the stalls. Beef grinned and his cock chubbed up more, realizing how big and tall he was getting. “Get on your knees, Beef,” Austin commanded, and Beef dropped down; he still came up to Austin’s chin even on his knees. “Now, get on all fours,” Austin said, and Beef pressed his big hands against the dirty floor of the bathroom stall; he looked up at his Sir with expectant, hungry eyes. “Good boy,” Austin said as he pulled his gym shorts down to reveal his own hard, throbbing cock. He ran a hand through Beef’s sweat-slicked hair and down his cheek to his thick beard. “Suck,” Austin said simply and stepped forward, rubbing his cock against Beef’s lips. Beef obeyed and opened his mouth. Austin groaned as Beef’s powerful lips sucked harder than he could believe, his prickly beard and mustache tingling along his cock. Beef was hungry, and his Sir’s sweaty cock excited him greatly; he slurped and grunted and licked and sucked greedily. Suddenly, someone else came into the bathroom, the door opening with a thump. The small room was filled with Beef’s grunting, moaning, and slurping sounds and Austin’s dirty talk. Beef felt so embarrassed but he sucked harder. He had to make his Sir happy. The stranger came closer and saw two massive meatheads sharing one stall, raised his eyebrows, apologized, and awkwardly left the bathroom. “Fuck yeah, everyone knows you’re my bull now, Beef, mmmph, take my fucking load!” Austin grunted as pleasure rippled up his spine. Austin exploded and Beef slurped up his thick load. “Mmm, good boy,” Austin said as Beef rose back up to his full, massive height. Beef grinned down at Austin and rubbed a knuckle against his lip, wiping a dribble of cum from his beard. As they left the bathroom, they passed by the wrestling practice room, which was a small, secluded room full of wrestling mats and practice gear. It was behind a locked door, but because Austin had a prestigious spot on the football team, he had a master key for every door at his college’s gym. “Hey Beef, wanna wrestle?” Austin said with a smirk. Beef’s eyes lit up. “YEAH!” he boomed as Austin opened up the door. The smell of stale sweat from years of wrestling practice and wrestling mats overwhelmed them as they entered the room. Austin closed and locked the door and they were alone. “Let’s see what we’ve got… here we go,” Austin said as he rummaged through a pile of dirty, used practice singlets. “This is the biggest one I can find, see it if fits.” Austin tossed the maroon-colored singlet to Beef, who raised it up to his nose and breathed in deeply, savoring the musk of wrestling practices gone by. He stripped down to his jock and struggled to put on the too-tight singlet, stumbling to keep his balance. “One foot at a time, there you go, mmm these are gonna stretch tight over your big thighs, huh?” Austin said as he helped Beef step into the singlet. It stretched and stretched, rubbing over the furry expanse of Beef’s massive thighs. Beef slowly rolled the singlet up the round expanse of his muscle gut, sweat already soaked into it, the material stretching and straining. Austin started putting on a singlet of his own, and Beef’s cock strained as he watched his hot master putting on the tight garment. A wet spot started forming on Beef’s bulging package, pre soaking through the singlet. “Sir, I need help with the final straps,” Beef rumbled. He waddled over to Austin and bent down, allowing Austin to reach up and stretch the straps over his huge traps. Beef’s meaty nipples poked out to the sides, his impossibly wide chest and shoulders too much for the singlet to handle. He rose to his full height, the straps taut between his traps and pecs, so tight they dug into his skin. His huge gut stretched the fabric so it looked more pink than maroon. “How do I look, Sir?” Beef boomed as he looked down at his master. “Like a champion heavyweight!” Austin said. He stepped forward and ran a hand across Beef’s lycra-covered gut, teased his meaty nipples that stuck out from the singlet, and bumped his knuckle against Beef’s absurd bulge. “Mmm, yeah, I’m the BIGGEST heavyweight around!” Beef boasted, then lifted his arms and flexed his big biceps. His musky stink was so strong it soon dominated the odor of the practice room, five minutes of Beef’s B.O. stronger than dozens of college wrestlers over years and year. “Let’s see if you can pin me, bud, I don’t think you can!” Austin said as he got into a wrestling stance and challenged his bigger stepdad. “Oh yeah?” Beef said as he advanced on his smaller master. “Come here, little guy!” Austin dodged out of his stepdad’s lumbering approach, but underestimated Beef’s long reach. Austin was surprised as the big man scooped him up and easily lifted him off the ground. Austin wheezed as the air was squeezed out of his lungs in an instant. “Bear hug!” Beef groaned as he flexed and crushed Austin against his enormous torso. He flailed his smaller master around, the tight lyrca singlets rubbing against each other, Beef’s sweat soaking Austin’s singlet, before squashing him down on the mat. Austin groaned as he was crushed under his bull’s tremendous weight, pressing him hard against the wrestling mats. “Takedown!” boomed Beef as he readjusted his position on top of his tiny master. He gripped Austin’s forearms, which felt so small and fragile in his huge hands, and pinned his wrists to the ground. He shifted his weight up, settling his hips and ass on top of Austin’s thighs and crotch. His gut pressed against Austin’s chest. Austin pushed against it to try to shift his weight, tried to slip his wrist out from Beef’s vice grip, tried to flip his hips over and around to fight back, but it was all completely futile. “Are you fighting back, Sir? I hardly feel anything! I’m just so much BIGGER than you, huh?” Beef growled, leaning down to whisper in his Sir’s ear. “Feels real good, feeling you struggle and squirm underneath me, Sir. You fight back so hard,” Beef said as he rubbed his leaking bulge over Austin’s torso. “But it’s pointless, I’m TOO STRONG!” “Huuffff, uff, you, huuuuff, you haven’t beat me yet!” Austin groaned under Beef’s mass. Beef just laughed. “Ha! Try your hardest, little master. I can barely feel you push back. Go ahead, try,” Beef said, shifting his weight even harder on his little captive. Austin pushed back as hard as he could, using all his jock strength, his face straining as he struggled against his stepdad’s overwhelming mass. “Hmmmm I maybe felt a little push of something underneath me?” Beef said, sweat dripping down onto Austin. Beef’s wrist-thick cock throbbed as it rubbed against Austin, lycra on lycra, the swish sound of singlets rubbing together filling the air. He leaned down even harder on Austin until Austin collapsed against the mat, helpless and out of breath. “I think that’s a three-count, Sir!” Beef wrapped his huge arms around Austin and stood up, easily carrying his master. He adjusted his grip on Austin until they were face to face. Beef had a huge, giddy grin on his face. “Heh, so easy to pick you up and move around now!” he boomed. Jon shifted Austin around in his grip again and lowered him face-down onto the mats again, in total control. “Mmmm yeah, your ass looks so good in the singlet, Sir,” Beef boomed from above Austin. Beef shifted his singlet straps off of his traps and over his huge shoulders until they hung at his sides, breathing a sigh as the tight singlet no longer dug into his skin. His chest and shoulders seemed even bigger without the straps on. “Beef wants to fuck little master so bad,” he rumbled as he fell to his knees and straddled Austin, pressing his huge lycra-bound bulge against the smaller man’s ass. “Big Beef fucking his jock stud Sir, mmmmh yeah, fuck,” Beef growled, his self-control fading, his primal instincts bucking against Austin’s control. He rubbed his cock against Austin’s singlet, leaning down harder and wrapping a huge bicep around Austin’s neck and pulling back hard to press his cock in harder. “Mmm yeah, so much fuckin’ BIGGER than you, Sir… and still GROWING!” Austin’s face was turning red and he felt the weight and pressure from his stepdad’s gigantic arm threatening to crush his windpipe. Beef’s cock pushed harder against his ass, spurting wads of precum; Austin could feel the wetness through the sweaty singlets. He knew he couldn’t keep him waiting much longer, but he knew there was one more thing he would want even more right now. “Well, big Beef, you know what you need to keep growing?” Austin choked as he best he could, voice strained as Beef squeezed harder and harder. “Food!” Beef’s gut growled loudly; hadn’t he just eaten less a couple hours ago? But suddenly he realized how starving he was, how much he NEEDED to eat and fuel his gains and feed his growing muscles and have MORE. “Oh, oh yeah! You’re right, Sir!” Beef said loudly as he let go of Austin and stood up suddenly. Austin shook his head as he got up, took a deep breath, and turned to face his giant daddy bear. That had been close. “Now Beef, you know better than to pin your Sir down without his permission, don’t you?” Austin said, putting his hands on his hips. Beef sheepishly rubbed the back of his head. “Yes, Sir, I just got, um,” he sighed heavily, his cock throbbing. “I guess I got a little carried away, Sir,” he said with a grin. “I’m just so excited to be around my hot little stepson Sir, and I—” he explained before Austin cut him off. “Shh, it’s ok, big Beef. I understand,” Austin said as he stepped closer to rubbed his hands over Jon’s sweaty lycra. “It’s hard to contain all your big bull energy, huh?” he asked as he reached down and rubbed Jon’s bulging cock. “Y-yeah,” Jon gasped, his knees shaking as his master played with his bulge. “I just want you so bad, sir,” he rumbled. “I know, Beef. And you’ll have your chance. Just don’t forget who’s in charge,” Austin, grabbing and tugging on Beef’s chain necklace and running his hand over the padlock. “Y-yes sir!” Jon said. “But for now, let’s go have lunch,” Austin said. Beef’s eyes lit up in excitement. “Get out of that singlet and let’s go!” They quickly changed, leaving their sweat and precut-soaked singlets on the mats, and Austin hooked the leash back up to his stepdad. Austin could hardly keep up as Beef rumbled towards the cafeteria, tugging at the leash; the big man was sniffing the air and following his instincts. They entered the cafeteria, and the workers stopped and stared at the massive, half-naked man on a leash. Beef’s eyes lit up when he saw all the food. “Wow! There’s so much! And so many options!” Beef boomed as he looked back at his master. “Let me take care of it, big guy. Just carry the trays and I’ll stack up the food.” Austin loaded up on chicken breasts, pasta, milk, a whole pizza, and more. When they were finished, they were carrying half a dozen trays loaded up with food, Beef balancing them between his big hands and meaty chest. “Have at it,” Austin said when they were seated; he made sure they were at a prominent spot where everyone could see them. Beef proceeded to inhale everything with shocking speed, devouring and consuming every bit of food in front of him, barely pausing to take a breath or wash down the food with greedy gulps of whole milk. “More,” Beef grunted as he finished the first tray, and Austin slid the second one in front of him. Beef continued to eat and eat. “More!” he boomed as he finished another tray. “More!!” he rumbled, his belly bulging with so much food that he had to adjust his chair. His breathing became slower and heavier, his massive shoulders slumped over the table, bent over to eat more food faster. “MORE!!” Austin kept it coming, grinning and encouraging Beef, eventually moving around next to him to rub his sweaty gut and feed him when Beef struggled to finish the last tray. “Good boy, you’ve had so much! The more you eat, the more you grow,” Austin said, a mantra that he sent along to his stepdad almost every day via text message, and Beef nodded. “Soon all this food will fuel more gains and help you get even bigger. You know, you’re getting so close to 1000 pounds,” Austin said as he rubbed his stepdad’s round, hard gut in wide circles. “Mmmmph,” Beef groaned around a mouthful of chicken, his cock throbbing in his jock strap. “Half a ton of bulky, meaty muscle. How do you like the sound of that?” Austin purred, leaning close to his daddy. Everyone stared, and Beef knew they were all staring. He blushed and sweated but Austin’s words also gave him butterflies in his stomach. “MMMph!” Beef grunted, imagining himself getting even bigger. “M-more!” he groaned, and leaned back in his chair and clutched his gut. It was stretched out, the top of it pushing and bunching up his BEEF crop-top even more. “Awww good Beef, you want to grow more for your Sir, don’t you?” Austin said, squeezing and rubbing his stepdad’s enormous bicep and shoulder. “Such a good boy.” “Y-yeah, bigger,” Beef groaned, then burped and gulped down the last of his food. “Always bigger for you, Sir!” “Mmm this is why I love you so much,” Austin said. “But I made a promise earlier this morning. Do you remember it?” Austin said, leaning closer and nearly whispering. Beef gulped and his massive package throbbed. “Yeah!” Beef rumbled. He pushed his chair back and rose to his full height. He swelled out his chest and then erupted with the loudest, deepest belch that Austin had every heard. “When we go home after lifting and eating, I get to cum,” Beef boomed loud enough for everyone around them to hear. “That’s right,” Austin said, rising out of his chair as well. “And today is very special,” Austin said. He reached up and tugged on Beef’s chain until he was leaning down to Austin’s level. “Today, you get to fuck your master and fill me with your thick load,” Austin whispered. Beef’s eyes bulged wide and the hair on his neck stood up. His cock throbbed and until it was rock-hard. “Y-you mean it, Sir?” he sighed desperately. “Uh huh,” Austin breathed, his breath tickling Beef’s ear. “I need you to stretch out my meaty bubble butt,” he said. “Yeah?” Beef panted, his chest heaving. “I need you to fill up my tight hole,” Austin teased. “Yeah??” Beef grunted, louder and more excited this time. “I need your cum inside me, Beef, for you to pound me senseless, and I want you to carry me back to the dorm right now,” Austin commanded. “YEAH!!!” Beef boomed, then picked his Sir up and threw him up over his huge shoulder. “FUCK YEAH, gonna fuck you GOOD, Sir!” Beef roared and stormed out of the cafeteria, the wet spot on his compression shorts growing.

Previous chapters: Chapter 1 Chapter 2 Chapter 3 Chapter 4 Chapter 5 Chapter 6 Chapter 7 Chapter 8 Beef, or rather Jon, finally gets to fuck his little master. Austin decides he can't live away from his growing stepdad any longer. Beef practically ran across campus, holding Austin in a fireman’s carry, grunting and woofing excitedly, panting and sweating and growling. He took the stairs up to Austin’s room three at a time and burst the door open, busting through the lock with one shove. He set Austin down, pushed him into the room, then wedged himself through and closed the door as best he could. Turning to Austin, he towered over the college jock and looked at him with an expression Austin had never seen before: unbridled, uncontrolled, overwhelming lust. “Beef wants to fuck!” he boomed, tearing at his compression shorts and jock until they tore off. His enormous cock sprang forth, drooling precum in a thin line of ooze that dripped to the floor. “Beef NEEDS to fuck!” he said as he stepped towards Austin. There was no doubt that everyone in the neighboring rooms could hear Jon’s words. “Yeah? You want my tight jock butt, Beef?” Austin teased, backing up and towards the middle of the room. “YES! I NEED IT NOW!” Beef rumbled, reaching for Austin with his huge, powerful hands. His lifted Austin up, pinned him to the ceiling, and tore at Austin’s shorts and underwear and shoes until they all fell to the floor. “Mmm, Beef is excited to fuck his Sir, isn’t he?” Austin continued to tease. “It’s gonna feel so GOOD to put that big cock inside me, huh?” Austin said. “MMMMMPH FUCK,” Beef groaned as his cock spurted pre. “Tight fucking HOLE for Beef to FUCK,” he said. He swung Austin down and wrapped his huge hands around Austin’s shoulders, gripping him so tight it hurt. He effortlessly lifted him off the ground, his tremendous arms bulging with power, his cock aimed right at Austin’s waiting hole. “Stop!” Austin said, and Beef immediately froze, holding his stepson in the air. “Good boy. You’re such an obedient piece of Beef. You worked so hard today, and I’m proud of you. Before you fuck me, you need to loosen me up. You’ve got a big monster cock, don’t you?” Austin said. Beef breathed heavily out his nose, huffing and puffing. “Y-yeah, I sure do,” he breathed, calmer than a moment ago but shaking as he held back, his sweat-soaked crop-top heaving up and down as his pecs switched in anticipation. His cock oozed precum onto the floor in heavy drops. “Then rub that slick precum up against my hole, slowly,” Austin said. Beef lowered him. “Oohhhhh, fuuuckk, rruuuuhhhh,” Beef groaned as his huge cock rubbed against Austin’s firm, round bubble butt, the huge cock head pressing against the furry, tight hole, smearing ooze all around. “Oh fuck yeah dad, feels so amazing,” Austin breathed. “So fuckin’ strong, just holding me in place,” he said. “You’re so light, son, you weigh nothing to me,” Beef grunted through gritted teeth. “Gotta fuck you so bad, kid, uuuuhhhhrrrrffff,” the monster rumbled. “Press against my hole harder, Jon,” Austin whispered. Jon’s eyes widened and a wave of emotion flooded into him as Austin used his real name. “Austin, I love you so much,” Jon groaned. The pressure from Jon’s cock became more and more insistent, pressing harder against Austin’s tight hole until it gave way. “You’re so big, so perfect, and I had so much fun today, you mean more to me than you’ll ever know, dad,” Austin breathed. Jon teared up and he became totally overwhelmed by Austin’s words. “I’m going to fill you up with my love, every inch,” Jon grunted and he pushed his cock in harder. Austin’s tight hole wrapped itself around Jon’s cock head like they were made to fit together. Austin groaned loudly, his stepdad stretching him out in a way he had never felt before. Jon pressed down harder, easing Austin down slowly but relentlessly with perfect control. “Oh my god Sir, it feels so incredible,” the huge muscle bear groaned. “You’re so fuckin’ tight… and I’m so fuckin’ HUGE!” Jon boomed. “Yeah that’s right, bull, so massive!” Austin groaned as his stepdad’s cock invaded him. “And you’re, ahhhh, just gonna keep, unnnfff, growing BIGGER!” “FUCK YEAH,” Jon roared as he pushed and pushed, faster and harder now, Austin sliding inexorably down Jon’s shaft. “So big, so thick, so STRONG!” Jon grunted until Austin was all the way in, 14” long and as thick as a beer can filling Austin. Heat and pleasure and pain radiated through every nerve of Austin’s body, and he breathed deeply and moaned and shuddered as his dad lifted him up slowly, then slammed him back down hard. “Unnnffff, fuck!” Jon grunted, his voice shaking with lust. He slammed Austin down again, making him cry out. “RrrrrRRRuuuuFFffffuck,” the big man groaned. Again. “OOOHHHHHH yeah!” Jon kept this up for several minutes, slowly lifting Austin up and slamming him back down in mid-air, his incredible strength lifting the 230lb jock like up and down like he weighed nothing, his cock impaling his stepson again and again and again. Ripples of pleasure shattered Jon’s mind over and over until his eyes glazed over. His body was soon covered in a shiny gleam of sweat, the sweat dripping until the rug underneath them was dark and damp. Austin leaned in closer and pressed his lips against Jon’s, their tongues intermingling with each other, pressing and probing as they made love, grunting and rubbing their beards together. Jon increased his pace as their kissing intensified, each of them breathing hard through their noses, Jon’s heady pit musk filling the room as he exerted himself, the stink becoming the dominant smell in the room and overriding Austin’s. “Mmmoooore,” Jon groaned as his cock swelled thicker and his balls tightened. “MMMOOOOOORRRE!” he growled as he increased speed, Austin’s ass slamming down harder and harder. “That’s right, bull,” Austin groaned, his voice quavering with each thrust. “You’re just gonna keep growing bigger, aren’t you?” he asked. “Fuck YEAH,” Jon growled. “Fuckin’ BIGGER!” he bumped his head against the ceiling to emphasize his height. “Already so fuckin’ HUGE, but just gonna keep GROWING MORE!!” the monster groaned. “Hell yeah, pup, my big bull, unstoppable GROWTH, you haven’t even started to grow yet, you’re gonna get so much BIGGER still!” Austin moaned. “Look at yourself in the mirror, dad, just look at the size and POWER you have!” Jon turned and saw himself in the full-length mirror. He gasped at what he saw. His massive biceps bulged with power, a huge round peak flexing with every thrust, lifting and pushing his big jock son up and down like he was a child. His round gut bounced and jiggled, Austin’s hard cock pressing against it and smearing precum against its hard, furry expanse. His shoulders and traps consumed his neck, and his thick beard trailed down until it brushed against his shelf-like pecs. His enormous legs bulged with power, swollen with a huge pump from the gym, and his whole body was red and ruddy with exertion, slick and shiny with sweat. Austin’s round, bulbous ass wrapped tightly around his massive cock, which was red and slick and pulsed with thick veins as he watched it go in and out of Austin’s hole. He was an absolute beast, and deep down he knew he was only just beginning to tap into his potential for size, power, and obedience. “Goddamn I’m so fuckin’ BIG,” Jon grunted, rearing his head back and growling with pleasure. “I’m gonna keep feeding you and breeding you, dad, gonna force more and more growth into your enormous muscle bull body!” Austin grunted, his own cock swelling closer to climax as it rubbed against Jon’s firm gut. “Uuuuhhhhffff, Sir, that sounds so good, I need that so much, I need MORE!” Jon boomed. He looked in the mirror again and thought of how much smaller he was a few months ago and laughed. He owed everything to Austin, his little Sir, his perfect, sexy stepson who was writhing with pleasure in his arms at this very moment. Jon looked into Austin’s eyes, and then two of them connected, madly in love with each other with an intensity that overwhelmed both of them. “I’m… I’m gonna…” Jon groaned. “Yeah daddy?” Austin said. “I love you so fuckin’ MUCH, son, now take daddy’s big fuckin’ LOAD!!!!” Jon roared. “Yeah!” Austin moaned and both of them exploded at the same time, Austin’s load spraying all over Jon’s torso and Jon’s jetting inside Austin so forcefully that Austin could feel his insides filling with the warmth of his dad’s potent muscle cum. They both shot spurt after spurt of cum, fueled by their epic gym session, public play, and enormous lunch. Cum gushed and rubbed between each other and dripped down to the floor until the room reeked of brawny alpha males. Jon lifted Austin up until he heard a slick, slurping *pop*. Austin groaned at the sudden emptiness he felt without Jon’s cock inside of him. Jon lowered Austin, sliding him against his slick torso, until his feet hit the ground, still holding him in his arms gently. He looked down at him and smiled. “I love you, little Sir,” Jon said, then leaned down for another kiss. Austin tilted his neck back and opened his mouth, tasting his muscle pup’s tongue. When they came up for air, Austin couldn’t help but smile. “I love you too, pup. Now, how about we shower?” “As long as we can do it together and that we don’t have to wash my pits,” Jon rumbled, swelling out his chest bigger. “Heh, we’re gonna freak out all my dorm mates even more with you walking around looking like that,” Austin said and rubbed the cum and sweat mixture into his dad’s furry chest, causing the hair to curl into ringlets. “Mmmm yeah? I love that,” Jon grunted, realizing the things he would have found embarrassing or humiliating a few months ago turned him on immensely now. “We should keep the curtains open in the shower so everyone can see. Who’s going to stop us?” Austin shook his head. “Jon, I can’t just send you back home after this. We share something so powerful when we’re together,” Austin said, stepping closer and wrapping his arms as far as he could around Jon. “I need to be closer to you, to be your Sir and help you maximize these incredible gifts you have,” Austin said, rubbing his hands up and down his stepdad’s enormous arms. “I’m going to find a way to take the rest of my classes online so I can live with you at home. How does that sound?” Austin looked up at Jon and saw that the big man had tears welling in his eyes. “Do you mean it, Sir?” Jon said, his voice shaking. “Yes pup, I do, I need you, I need you every day,” Austin said as he buried his face into Jon’s furry chest. “I want that so much, Sir, you would make me the happiest, luckiest pup in the world!” Jon said as he reached down until his hands cupped Austin’s meaty ass. He lifted Austin up and squeezed him harder than ever. Austin groaned as his giant muscle bull hugged him hard. “We can fuck and lift and eat and grow bigger and bigger together, finally!” Austin wheezed. Jon squeezed him even more tightly, his cock throbbing and his muscles bulging “Fuck yes!” he roared before leaning down to make out with Austin again.

Previous chapters: Chapter 1 Chapter 2 Chapter 3 Chapter 4 Austin takes Jon to the doctor to figure out how his huge stepdad is growing so fast. They use the opportunity to have some fun with Jon's new size at the doctor's office. Chapter 5: Christmas Break Checkup Austin told Jon to drive, and they both piled into Jon’s souped-up, lifted truck. The thing weighed over 2 tons but it still lurched to one side as Jon hauled himself up into the cab. Even with the size of the vehicle, Jon’s massive, wide shoulders still pressed against the driver side door and threatened to creep into Austin’s passenger side space as Jon started the truck, the diesel engine rumbling to life. “Where to, Sir?” Jon asked, turning to Austin and smirking. Austin loved how much Jon was increasingly asking him for everything and waiting for guidance and direction even on everyday sorts of tasks. “First, to the doctor for your check up, then dinner,” Austin said as he typed in the directions on his phone and they pulled out of the driveway. “But Sir, I’m hungry now,” Jon complained, his grumbling tummy audible even over the rumble of the diesel engine. Jon’s huge truck towered over all the other cars on the street, and Austin sort of felt like he was in a monster truck. It certainly matched up with the size advantage that Jon sported over normal people. “Well pup you’re gonna have to wait. I want you to be EXTRA hungry for your big dinner so you can eat as much as possible,” Austin explained. Jon sighed and pouted. “Ok Sir… I’m gonna eat SO much when we’re done!” They pulled into the parking lot and got out of the truck. Jon tugged at his too-small polo, trying in vain to cover up his protruding belly. His sleeves crept up and up his arms as he walked until they were pressing against his pits, cutting into the wide bulk of his upper arm like a tourniquet and exposing his huge biceps. He tried adjusting the sleeves a little but it didn’t do much good; his arms were just too big. His gym shorts rode up into his massive bubble butt and only came halfway down his thighs. He blushed as they approached the door. “Open the door for me, pup,” Austin said and Jon complied, holding it open for him. He followed Austin inside, ducking and turning to fit inside the doorway. The receptionists and patients waiting in the lobby all turned and looked at the massive man squeezing through the doorway, some of them gasping audibly. It wasn’t everyday you saw one of the largest men on Earth. They got checked in, Austin doing all the talking and handling Jon’s documents. The receptionist thought it a little odd but was too distracted by the huge man in front of her, his clothes barely covering his mass. They made their way to the waiting area. There were a few other people there, and they openly gawked at the enormity of the man who had just walked in. A wave of BO stink preceded him, causing some to wrinkle their noses and move to another seat. Austin sat down in a chair, and Jon tried to sit next to him. His massive thighs and wide ass wedged down into the chair, and it clearly wasn’t wide enough. “Go on, Jon. Sit down in the chair,” Austin said, encouraging the bigger man. “You can fit…probably. Give it a try,” Austin said with a smirk, knowing what was going to happen. “O-ok Sir, but I don’t think…” Jon started and suddenly stopped when the arms of the chair creaked and cracked. “Maybe I shouldn’t—“ “Jon, sit in the chair,” Austin insisted. Jon continued lowering his bulk into the chair until the wooden arms of the chair cracked and splintered, bending outward at a 45 degree angle until Jon was sort of wedged into the chair. His shoulders spread wide enough for three seats, his delts spilling over in front of Austin; Jon was hunched over trying to fit. “Hah, you broke it! You’re getting too big for normal furniture,” Austin teased as he rubbed his stepdad’s big shoulder. “Heh, yeah I guess so,” Jon said, blushing, embarrassed. He stood back up and the chair came with him before dropping to the ground with a clunk, ruined. “Come sit on the floor instead,” Austin said, pointing to the space between Austin’s thighs. “O-Ok Sir,” Jon said, his face flushing a deeper red across his chubby cheeks and under his dirty blonde beard. He sat, shaking the waiting room with his 500+lbs as he did. “That’s better,” Austin said. He spread his legs out wider to make space and he rubbed Jon’s thick neck, playing with his thick neck folds as they waited. Jon purred in appreciation, a deep, growling sound of satisfaction as Austin’s strong hands massaged him. Several of the other people in the waiting room gave them weird looks, and Jon felt a little self-conscious, but Austin reassured him with a pat on the shoulder. “I’m so excited to see what the doctor says,” Austin said, leaning down to whisper in Jon’s ear. “You’ve gotten so big so fast… I bet he’s never seen anything like it, you big freak,” Austin said, grinning. Jon’s cock swelled and bulged as Austin spoke. “Y-yeah? A freak? Never seen a bull growing like this huh?” Jon said and he raised his right arm to flex his huge bicep, the peak straining the tight sleeve of his polo shirt, pushing it back until the entire upper arm was exposed again. A wave of jock stink spread through the small waiting room, becoming inescapably strong. Austin breathed in the heady scent. “I bet he hasn’t,” Austin said, squeezing his bull’s big bicep and then smacking it. It was hard and hot to the touch and had a thick, throbbing vein coursing over it. “Jon!” the receptionist called outa while later. Jon rose to his feet and the nurse gasped audibly. Austin and Jon headed back to the exam rooms, Jon’s walking gait now decidedly a waddle that made the floor vibrate, his massive thighs rubbing against each other, his package impossible to hide, pushed forward from the girth of his quads. “H-hello, come on in, and you are?” she said, addressing Austin. “The stepson. I’ll be handling any questions about my father’s health.” Austin said authoritatively. “Alright then, well, hop onto the scale big guy,” she said. “Sure thing!” Jon said affably as he stepped onto the scale. He liked being called “big guy”. *Clank* *Squeeeeee* *Ping* The metal scale made a distressing series of sounds as Jon stepped on, and the needle on the scale, which at first rose sharply, fell back to zero. “Looks like I broke it!” Jon said, lifting an arm up and scratching the back of his head in embarrassment. The nurse wrinkled her nose and stepped back as a fresh wave of Jon’s musk emitted from his exposed armpit. “T-that’s ok, um, let’s just write down…,” “504 as of this morning, though he might have added some since then,” Austin said sharply. “Ok then, and let’s check your height,” she said. “Back up against the wall there and take your shoes off,” the nurse directed and Jon complied, his huge Otomix lifting shoes clunking heavily as he removed them, the smell of his feet acrid and musky. The nurse quickly realized that she couldn’t reach all the way up to the top of his head. “Jon, help her out, would you?” Austin said, and Jon reached out and grabbed the diminutive nurse. She was probably a quarter of his weight and over a foot shorter. She yelped as his huge hands wrapped around her waist and she rose into the air. “Up we go!” Jon said as he lifted her up so she could reach the scale. She adjusted it until it leveled with Jon’s head, 6’8”. Jon put her down. Looking disheveled, she walked them to an exam room and shut the door. “Well, I don’t think they’ve ever had someone break the scale before, pup,” Austin said as he moved closer to his huge stepdad. “I really get a sense of how big you are next to all these normal-sized people.” Jon grinned. He spread his shoulders wide, rose up to his full height, and puffed up his chest proudly. “Heh, yeah!” A knock came at the door and the doctor entered. He was a short man, probably just 5’4” or so and lean, and his eyes bugged open when he saw the size, and smelled the musk, of the giant in the exam room. “Whoa! So, what brings you in today?” “Just a routine physical for my father,” Austin said, taking charge. “He’s had quite a growth spurt lately and has been responding exceptionally well to my training, and I want to make sure he’s in good shape. What do you think about his size, doc?” Austin asked. “Go on, show him Jon.” “Sure!” Jon said and he brought his arms together in a most-muscular pose. “GRRRRR yeah I’ve been really putting on size since my son here started training me! I love growing bigger,” Jon grunted through gritted teeth as he flexed as hard as he could for the doctor. His chest heaved up and down as he flexed and bounced his pecs. “MMMphh, mmmmphhhh, yeah!” Jon grunted. “I, well, I mean,” the doctor sputtered, flabbergasted by the display of size and muscle in front of him. “I’ve never had a patient like you before! Let’s go ahead and take a look. Hop up on the exam table.” Jon did just that, which caused the table to raise off the floor on the other side, nearly tipping it over. Jon slipped off of it and the table clanged loudly back into place. “On second thought, uh, you could just stand. Let’s get your vitals,” he said. “I brought the extra large cuff here so that should work fine for your blood pressure,” he started, before holding the cuff up to Jon’s arm. He wrapped what he could around it, but it was several inches too short. The label said it was big enough for 20” arms. “That’s not going to work, I promise,” Austin said with a smirk. “Jon’s grown too big for that, isn’t that right pup?” Jon grinned and flexed his huge upper arm, the mass and veins and peak of it swelling bigger. “Mmm hmm!” “A-alright then, uh, well, I could get the adult thigh size cuff, but for now let’s get a blood sample and then I’ll ask some questions,” the doctor said. He proceeded to get a couple vials of Jon’s blood and sent those to the lab. “Well, last time you were in you were…” the doctor started, before scrolling through the info on the computer a few more times with a confused look on his face. “…5’10” and 175 pounds? That can’t be right, that was just a few months ago,” he said. “No, that’s right,” Austin said from his chair. “Like I said, my father has been making significant progress on his body over the last few months under my care. Tell him about some of your gains, pup,” Austin said, nodding to Jon. “Sure son! I’m about 500 pounds now, I can bench, deadlift, and squat over three times my weight for each exercise, my biceps are at least 26” around, thighs are bigger than most peoples’ waists, I eat 12,000 calories a day at least, and I just seem to keep growing and growing! Oh, also, I’m 6’8” now so I’ve grown about 10 inches in the last 4 months too,” Jon said, rattling off the info. He stepped closer to the doctor, who was seated with his back to Jon, and Jon loomed over him, casting him in shadow. Jon was turning himself on a bit as he thought about how much bigger and stronger he was getting. His bulge shifted in his tight jock strap and he reached down to adjust himself, smelling his musky hand afterwards. “That… that shouldn’t be possible… you’re a 42 year old man! You shouldn’t just gain 300 pounds and grow almost a foot in a matter of months!” the doctor exclaimed. He looked over his shoulder and saw that Jon was standing over him. The big bear grinned down at him, his polo taut over his massive chest. The doctor stood up from his chair and retreated to a corner of the room to give himself space. “It’s extraordinary, doctor, we know. But all that matters is that he’s healthy and that he can keep growing bigger,” Austin said, standing up and patting the doctor on the shoulder with a reassuring hand. The doctor immediately relaxed, which he knew deep down he shouldn’t feel with such an unusual and alarming patient, but he felt it nonetheless. “You-you’re right of course. Yes. Absolutely, he should keep growing!” the doctor said enthusiastically. “Glad you can see it our way!” Austin said, smiling. "Let’s see what the blood work says, it just got finished at the lab,” he said as he sat back down. “Ok, blood work, and… wow!” “Wow? Wow good, or wow bad, doc?” Austin said. “Wow, I’ve never seen these kinds of readings before. They’re not necessarily indicative of any health issues, but… growth hormone, testosterone, luteinizing hormone, pituitary activity, it’s all just… totally off the charts! Like, look here,” he said pointing at some numbers on the screen. “This number here is about ten times what we see in teenage boys going through puberty. It’s like he’s going through some sort of second growth spurt but magnified into adult-sized proportions.” “And on top of that I’m feeding him a diet to maximize growth and pumping him full of supplements and steroids,” Austin said proudly. “So, what you’re saying is…?” “What I’m saying is,” the doctor said as he stood up. “Jon is just going to keep growing, and there’s nothing at all wrong with his health. On the contrary, he’s one of the healthiest 42-year-old men I’ve ever seen,” Jon grinned at that. “Alright! That’s great news!” he said and he wrapped his arms around the doctor, pinning him against his firm belly. The doctor squirmed and tried to say something as his face was pressed between Jon’s pillowy pecs, but all that came out was a muffled “Mmmmph!” “Jon, let him go… he still has a couple other things to check,” Austin said. “Doc, I’d like you to do a more close-up physical exam. Jon, take your shirt off and doc, look for any suspicious moles, will you?” They both obeyed Austin quickly. Jon struggled out of his tight shirt but eventually got stuck with his arms over his head. “Uh, a little help?” the big man said, his face obscured by his shirt, his belly and pecs exposed. “Heh, sure thing dad, lean over,” Austin said. He grabbed the tight shirt sleeves as Jon bent over and he pulled, tugged, and wriggled the shirt around until it was free from his huge stepdad. Jon staggered backwards and sighed, then stood back to his full height. He stepped forward closer to the doctor and puffed his chest out, looking down at him with a grin. “Wow!” the doctor breathed as he took in Jon’s full musculature now that he was shirtless. “Well you certainly are adding some muscle mass,” he said, trying to sound professional, but his voice wavering. He walked around Jon looking for moles. “So you were just an average build before this, then?” he asked. “That’s right,” Austin said, speaking for his father. “I gave him a new training regime this fall and he has responded to it beyond my expectations. Our mutual goal is to keep growing as big as possible, isn’t that right Jon?” Austin said. “That’s right, bigger and bigger!” Jon said happily. The doctor stood in front of him and Jon flexed his chest slightly for him. His dense, dirty blonde chest hair was curled into ringlets from sweating so much earlier. “Jon, go ahead and pick him up like you did with the nurse,” Austin said with a smirk. “What? I don—whaaaa!” The doctor yelped as he flew into the air, his head almost touching the ceiling. “Heh, you’re so light, Doc! What do you weigh?” Jon said as he bounced the doctor up and down like a child, brushing him against his furry chest and round, hard gut. “150! Put me down please!” he said as Jon played with him. “Heh, I’m more than three times your weight! And soon I’ll be even bigger!” Jon said as he set the doctor down, who took a few steps to steady himself. “One more thing before we leave then, doc. Jon, drop trou. Go ahead and check his balls for any issues. Those have been growing too!” Austin with a chuckle, unable to contain his grin. “They sure have!” Jon said as he unceremoniously yanked his pants down. His package bulged obscenely in his jock strap, which was stained yellow from weeks of intense workout sweat and leaking precum. He pulled the jock down too and his thick cock flopped out, slapping against his massive, hairy thigh. “Oh my, that’s not necessa… oh wow,” the doctor said as he stepped closer and squatted down. He crinkled his nose at the intense jock BO musk that radiated from Jon’s package. He cupped Jon’s balls in his hand and gasped. “My goodness, they’re as big as lemons…” he hefted them up and down, appreciating the sizable weight of them, struggling to be professional. “And growing bigger every day,” Jon said as his cock stirred to life at the doctor’s touch. “Gotta keep ‘em regularly drained too!” he said with a booming laugh. The doctor’s hands brushed against the furry undersides of Jon’s balls and Jon shivered. The doctor asked him to cough, and Jon did. His cock stirred to life, swelling and thickening quickly as the doctor shifted the grip on his balls. “Doc, what’s an average size for a man his height?” Austin asked, enjoying the size disparity between the two men. “5, maybe 6 inches for most Americans,” he said, watching Jon’s cock lurching and twitching as it grew. “Maybe a couple inches more for someone of Jon’s, um, stature.” “And how big would you say Jon is?” Austin said, smirking again. “Well it’s hard to say, but – oof!” the doctor said as a thick cock bumped against his cheek. Jon’s cock suddenly swelled bigger and lurched to one side, smacking the doctor in the face again. Jon grinned down at him and shifted his weight, his cock bulging to full hardness in a matter of seconds. He pushed it against the doctor again, making him lose his balance and fall over. “Oops, sorry doc. I’ve always been a grower not a shower!” Jon boomed from above. “Ha! Jon, your dick is so big it should be classified as a weapon!” Austin said with a laugh. “What do you think, doc? How big does it look from down there?” The doctor looked up at the two muscular studs above him, Austin the epitome of arrogant young jock, and Jon an unimaginably huge giant of a man, naked and hard. Jon grinned down at him from over the mound of his barrel chest, his round gut, and his swelling bulge and laughed. “It’s… enormous… definitely over 10” and I’ve never seen something quite that thick…” the doc sputtered. “As for Jon’s health, yes, everything looks… exemplary,” he said, adjusting his glasses and trying to salvage his pride. “Very good. You’re dismissed,” Austin said and the doctor immediately gathered his things. “Jon, be sure not to block the door…” Austin said with a wink. “Heh sure son,” Austin said and immediately moved to the door. His massive, wide frame wedged into the door frame, his head brushing the top of it and his thighs and shoulders just a bit too wide for it, still naked. “Hey, guys, come on,” the doctor said, flustered. “I have other patients to see,” he said as he tried to find some space to move past Jon. He pushed against Jon’s bulk, and Jon barely felt it. He refused to move, toying with the little man, gently pushing him back or shifting his weight. Jon hardly even had to try. The doctor tried to slip under Jon’s armpit, and Jon squeezed his head between his bicep and bulging lat, rubbing jock musk on the doctor’s face. Austin started laughing as he saw the little man’s futile attempts. Jon did too, and he reached out to palm the doctor’s head and hold him back at arms’ length. The doctor pushed against his wrist and tried to step forward, but it was pointless. “You guys… this isn’t funny!” he said. Austin laughed some more. “Sure it is!” “What should I do with him, Sir?” Jon asked with a twinkle in his eye. “Jon why don’t you help him now?” Austin said as he gathered up Jon’s clothes. “Take him back out to the hall.” Jon suddenly stepped forward and scooped the doctor up into both arms. He swung him through the door frame, holding him effortlessly. He then rubbed him against Jon’s furry chest and bounced him around, the doctor gasping and yelping as he did. “Pin him on the ceiling, Jon,” Austin said, egging him on. The big man did just that, raising him over his head and pressing him against the ceiling easily, dislodging a couple ceiling tiles. “Yeah, that’s great. Alright pup, enough messing around. Let’s go!” Jon smiled and he unceremoniously set the doctor onto the floor in a heap. “Later, doc! Thanks for the check up!” “Alright pup, now walk out to the lobby naked, I want to see everyone’s reactions!” “Naked? Me?” Jon said, suddenly blushing. “Ok Sir!” The massive muscle bear waddled back to the entrance, his bulk filling up the entire hallway as shocked nurses and patients parted before him. Jon liked the reactions he was causing, and he liked that Austin was bossing him around. His stomach growled ferociously and he remembered it was time to eat!

Previous chapters: Chapter 1 Chapter 2 Chapter 3 Chapter 4 Chapter 5 Austin takes Jon out to dinner at Fogo de Chao, the all-you-can-eat steak restaurant, and Jon eats his fill. Jon expresses his devotion to Austin in front of everyone, and the guys take their relationship to the next level. Chapter 6 — Christmas Break Dinner Austin walked into Fogo de Chao and checked in with the receptionist. Jon followed behind, ducking his head slightly to make sure he cleared the doorway and having to open both doors to fit his prodigious width through. When the receptionist looked up from his book, he gasped as he saw the enormous man suddenly standing in front of him. He eyed the big man up and down, perplexed by the comically small polo shirt that did a terrible job containing his stupendous bulk. He wrinkled his nose as the wave of BO stink emanating from the mountainous muscle bear hit him. He almost said something – people usually dressed and cleaned up before coming to this place – but gulped when he heard the big man’s stomach growl audibly. He quickly ushered them to their table after Austin confirmed their reservation. The table seemed small as the two big men approached it; it was right in the middle of the restaurant. Jon looked around a little nervously, self-conscious of how much he stood out in such a public space, especially in his too-small polo and tight gym shorts that only came halfway down his tree trunk thighs. “Sir, I didn’t know we were going to such a nice restaurant,” Jon said as he tugged a little at his shirt, trying to make sure his round belly was covered. “Only the best for my big guy!” Austin said as he sat down. “You look incredible. Everyone should be jealous of how massive and powerful you look, Jon. Give me a flex,” Austin said. Jon grinned as his master’s praise perked him up, and he brought his fists together to flex, his arms and traps stretching the already tight fabric of his polo. “Mmm yeah you like?” Jon said as he grunted. “Hell yeah pup, now let’s fill up that big tank and help you grow! Big bear needs plenty of protein to pack on more size,” Austin said. Jon carefully lowered himself into his chair. It was built for normal-sized people, not 500+lb musclebears, and it creaked ominously as he shifted his bulk down. He could see himself in a big mirror off to one side of the room and marveled at how huge he looked compared to the normal-sized tables and chairs and people; he hadn’t been out to many public spaces other than the gym since growing so much. His shoulders were three times the width of the chair he sat in, and his long legs easily stretched over to Austin’s side of the table. He scratched his salt-and-pepper beard and grinned, his bulge tenting a little in his tight jock; he liked what he saw. The waiter came by and explained how the restaurant worked, but they were both familiar with the all-you-can-eat steakhouse. Jon looked up at the waiter. “I’m gonna have this card on green all night, so you better keep it coming. I have a BIG appetite!” he said as he gave his belly a firm slap, the loud smacking sound making some other diners look their way. Jon blushed but grinned too. “It takes a LOT to fill this tank!” “Of course, Sir,” the waiter stammered as he dished up the mashed potatoes and fried candied bananas. “Jon, just how big are you these days? Just so the waiter knows what he’s dealing with,” Austin said, egging on his big musclebear dad. “Sure, son. I’m 6 foot 8 and just north of 500 pounds, as of this morning anyway. I’d like that number to be MUCH higher by the end of this meal!” Jon said with a laugh. He rubbed his gut, which gurgled loudly. “This tank needs to be FULL by the time I’m done!” he guffawed. Jon grabbed the whole platter of potatoes, brought them up to his mouth, and gobbled them up, spooning and scraping at the plate until they were gone. “I’ll, uh, be sure to get you more of those,” the waiter said, looking back and forth between the strange couple before taking off. Austin laughed and shook his head. Jon looked back at Austin, eager for approval. “Did you like how I did that, Sir? His face when he saw me rub my belly was priceless!” Jon said, bumping the table as he adjusted his swelling bulge. “That was great! I love how confident you are, pup, showing off for me like that. Get eating, bull. I’m gonna go get some things from the salad bar. Want anything?” Austin asked. Jon was too busy cramming bananas into his mouth to properly respond. “Whatever you don’t eat, I’ll take care of,” the big man said. Austin walked by Jon on his way over, rubbing his hand across his stepdad’s fresh high fade haircut and brushing his bulge against Jon’s wide shoulders. The first gaucho-waiter approached Jon’s table, looking slightly trepidatious at the massive man at this small table. “The house special?” he said, offering his skewer of meat. There were 3 medallions of glistening beef on the skewer, each one about twice the size of a hockey puck. “Just slide the whole thing onto my plate!” Jon said. He leaned back, the chair creaking painfully, and lifted his arms up to flex his biceps. “Gotta eat big to get big!” “S-Sir,” the waiter started, “I… very well,” he said, realizing he couldn’t say no to such a big man. He slid all three chunks of the house special onto Jon’s plate, the juice of the meat spreading around his plate, steaming and salty. “Mmm,” Jon growled as he skewered one with a fork, brought it up to his mouth and tore into it, devouring half of a chunk in one bite. Austin came back with two huge plates of veggies, cheese, and more, taking some for himself but leaving most of it for his hungry musclebull stepdad. “Looks like you’re off to a good start, pup,” Austin said. Jon just grunted and kept eating, his eyes glazed over in a food trance. More waiters came by, and Jon always took as much as he could, meat piling high on his plate. He ate it all; sausages, chicken, lamb, every cut of beef they had, bacon-wrapped pork chops, the juice of it all getting into his salt and pepper beard and dripping down onto his new polo shirt, which slowly rode up his belly as the meal went on. He even ate the gristle. “Look at you go, Jon,” Austin said after about 20 minutes. “You’re my big hungry bull, huh? Every bite is gonna make you bigger and stronger,” he said. “Yeah,” Jon said, rubbing a fist against the juice dripping down his salt-and-pepper beard. He paused briefly to wash down another filet mignon with a whole glass of wine, which he downed in three big gulps. “Are you impressed by how much I can take down? Been eating more and more everyday while you were gone,” he said as he tore into another lamb chop. “Seems like my appetite is growing as fast as my muscles are!” he said, taking a deep breath. His chest and belly swelled out and the table shifted back towards Austin, rattling the dishes and glasses. “Hell yeah, bull, you’re eating as much as a whole damn offensive line!” Austin said. “The more you eat, the bigger you grow!” “That’s – URRPP – right!” Jon said, a loud burp escaping his lips, drawing another round of stares from nearby tables. “Starting to sweat there, big guy,” Austin said, noticing the pit stains and U-shaped wet spots under his pecs. “Got the meat sweats, dontcha?” Austin teased. “Mmph,” Jon grunted, his mouth full of meat. He reached up and scratched at the fur that was busting out of the collar of his polo, his bicep swelling as he did. “Come on dad, I know a big lug like you can eat more, keep going!” Austin said. Another waiter approached the table to offer more of the bottom sirloin. “More,” was all Jon said. The juicy, warm protein triggered a feeding frenzy that went on for half an hour, Austin encouraging him, Jon eager to impress. Eventually, Jon got up, his massive gut bumping the table. His chair cracked dangerously as he did. He rose to his full height and towered over Austin. “Gotta lighten the load,” he said, hefting his sizable bulge as he grinned down at Austin, and waddled over to the bathroom. The big man opened the door and a face squashed into his belly as he collided with another dinner guest, causing the smaller man to stumble backwards. Jon didn’t budge. “Oops, sorry there bud. Sometimes it’s tough for me to see down that far!” Jon said with a laugh, measuring himself against the little guy he had nearly knocked over. He looked in the bathroom mirror and noted that the guy came up to his nipples, which poked out prominently from his painted-on polo. “Heh, uh, excuse me,” the little guy said, his cheeks red with embarrassment, and he scampered off. Jon approached the stall and realized he’d have to really contort himself to get in there. He turned sidewise and squeezed in just barely, his gut scraping against the door frame. He closed the door and turned, his shoulders pressing against the sides of the stall; he had never felt bigger. As he came back to the table, Jon’s stomach fluttered when he saw Austin, looking handsome and muscular in his tight dress shirt, his high-and-tight and lantern jaw and trimmed beard making Jon’s cock stir in his jock. He was so lucky to have such a handsome master. He approached Austin’s chair from behind and pressed his belly and bulge against him. “I’m back,” Jon purred from behind Austin, his deep, rich voice vibrating against Austin’s head. “I could feel your footsteps from halfway across the room, big man,” Austin said as he looked up at his stepdad. “You ready for round two?” he said as he beckoned Jon to sit again and resume his feasting. “Hell yeah,” Jon said as he sat down, then chomped into another lamb chop. Jon kept eating for another 45 minutes, stopping only to eat some carbs and wash it all down with more wine. Austin talked to him about lifting and football and the gym, Jon nodding and grunting and occasionally adding in a few comments before resuming his gluttony. The waiters asked them if they were close to wrapping it up several times, but Jon just said “Keep it coming,” “More!”, or “Not done yet!” Austin got more and more worked up as the meal went on, seeing his giant stepdad filling himself up with meat. Austin’s package bulged under the table, throbbing for most of the meal as he watched Jon stuff himself with reckless abandon, Austin watching his huge muscles twitching with every subtle movement. Jon seemed to swell up bigger as he ate and ate. After an hour and half, his shirt was half-soaked with patches of sweat on his back, chest, and arms, and it was stretched taut over his round, solid, full gut. He was breathing heavily through his nose, grunting and groaning after each bite. “Slowing down there, champ?” Austin said. “Come on, pup, you’re not done yet, are you?” *Huff, grunt* “No!” Jon said defiantly, forking up another big bite of steak and stuffing his face. “Gotta get full for you, Sir.” “I’m so proud of you, Jon,” Austin said. With that, he pushed his own fork off the table and onto the floor. “Oops. Get that for me, pup,” Austin said. Jon rose out of his chair, once again bumping the table, taking a huge breath and stretching before erupting into the biggest, loudest burp either of them had ever heard. Everyone in the restaurant looked over in shock and stared at the massive brute whose shirt only covered half his gut. “Unf, that’s better,” the big man said as he thumped on his belly and grinned. He lowered himself to his knees and reached for the fork. “Jon, look at me,” Austin said while Jon was on his knees. His big stepdad looked up at him, his blue eyes glistening. “Yes Sir,” Jon said, holding the fork in his hand. He steadied himself against Austin’s firm thigh. “Open wide, bull,” Austin said as he brought a huge piece of filet mignon to Jon’s mouth with his fingers. Jon opened his hungry maw and took the whole thing, his tongue brushing against Austin’s fingertips, chewing a couple times before gulping it down. “Mmmm good bull, still so hungry and eating right out of my hand,” Austin purred and he rubbed his hand through his stepdad’s short hair. “Yes Sir, feed me more, please,” Jon purred in his deep, rich voice, still on his hands and knees, needing it so badly, any sense of embarrassment overridden by the need to serve. “Good pup,” Austin said, as he got another piece of steak and brought it to his stepdad’s eager lips. “Such a good bull.” Jon grinned and plucked the steak from his master’s fingers gently, showing how much he appreciated it, then chewing quickly and swallowing hard. He opening his mouth up for more, begging shamelessly, panting like a dog. “Yeah bull, keep eating more,” Austin breathed as he leaned down to feed his stepdad. “Just imagine how big you’re gonna grow from this single meal.” “Mmmmph, more,” Jon purred as he gobbled up another piece, then another, then another until Austin’s plate was almost empty. “You’ve done such a good job these last few months, Jon,” Austin said, “Growing bigger than I ever imagined and devoting yourself to me.” He brought another piece of meat to Jon’s lips and the big man obediently slurped it up, his big lips wrapping around Austin’s fingers and leaving behind a trail of saliva. Guests at the other tables looked in shock and bewilderment at the enormous older man eating out of his stepson’s hand. “I couldn’t ask for a better father, especially after losing mom last fall. I want you to be part of my life forever, closer to me, pup.” He rubbed Jon’s huge shoulder and trap, feeling the firmness and size of Jon’s mass. Jon breathed heavily, overcome not just with several pounds of steak in his gut but with intense emotion unlike anything he had ever felt. “I want that so badly, Sir, I need it, to be your bull,” Jon breathed. It felt like everyone in the restaurant was watching them, this huge salt-and-pepper hulk leaning in close to his fit, muscular, younger companion. People whispered and ogled, and Jon felt nervous and sweaty, but elated and excited too. “Are you ready to be bound to your Sir, pup?” Austin said, as he reached behind him. Heavy, bulky chains clinked against each other as he pulled out a big metal padlock and chain necklace from a hidden pocket of his jacket, big enough to wrap around Jon’s massive neck and traps. The lock gleamed in the light. Jon’s heart fluttered. “You will be my good, obedient bull pup and live to serve your master. I will always be there for you no matter what, and you will be there for me and do as I say,” Austin said. Jon scooted closer and lowered his head into Austin’s lap. “Yes Sir, I want that more than anything Sir, I would be honored,” Jon said, his voice quivering with emotion. “Bullpup is ready to serve you.” “Good bull,” Jon said, lifting the heavy chain, wrapping it around Jon’s enormous neck and locking it into place. “Look at me, pup,” Austin said, and Jon did so, tears mixing into his salt-and-pepper beard. Austin put on his own smaller chain necklace, a large metal key at the end of it; Jon knew it was for his lock. Austin reached behind Jon’s head, gripping his neck rolls, and pulled him in for an aggressive, hungry, passionate kiss. They pressed together roughly, their tongues fighting against each other, beards scraping coarsely as they panted through their noses, grunting and growling. “Mmmph, good pup,” Austin said as he broke away, leaving Jon wanting more. “Now let’s finish this meal and get home. There’s more of that waiting for you there,” Austin said as he grasped the sizable bulge in his shorts and squeezed, making a wet spot appear through his khakis. “Yes, Sir!” Jon boomed loudly as he rose to his full height, towering over his smaller stepson. His gut bulged out prominently, his polo only reaching down to his belly button; belly and pec meat swelled out of his shirt, the sleeves straining to contain his massive upper arms, which had already pushed up to his delts. His shorts tented obscenely, and the meat sweats had only increased, jock musk spreading around their table from Jon’s potent pits. Jon reached up and felt the heavy chain and lock around his neck. It felt RIGHT, like something had been missing and was now in place; it was cool against the furry expanse of his chest, a reassuring, comforting weight against him. “Sir?” Jon said. “Yes, pup,” Austin said as he looked up. Jon suddenly reached down and grabbed Austin, hooking his big hands under Austin’s arms and lifting him right out of his chair like he weighed nothing. He lifted him up as high as he could, then lowered him down so they were face-to-face, their bodies pressing against each other. “I love you, Sir!” Jon said loud enough for everyone in the restaurant to hear. His cheeks were red, but his cock throbbed as he said it. Jon leaned in for a forceful kiss, grunting and planting his tongue on Austin’s lips. Austin could taste the steak and wine from dinner as he kissed back, Austin’s feet dangling several inches off the ground. Jon could feel the eyes and hear the shocked comments of everyone at the restaurant, and at first he felt nervous, self-conscious, and exposed. But as he kissed Austin and pressed his enormous, muscular chest against Austin’s, everything was right in the world, and all he felt was happiness. Finally Jon broke their kiss, and he held Austin at arm’s length, grinning. “Let’s go home NOW, Sir,” Jon said, and he scooped Austin up into his arms to carry him out. Austin looked around for the waiter and said, “Check please!” Jon and Austin could barely keep their hands to themselves on the way home, both of them reaching across the cab of Jon’s huge truck to rub the others’ leg or arm or neck, both breathing hard. When they pulled into Jon’s house, the big man came around to the other side to carry Austin inside. Jon scooped Austin’s formidable weight into his arms and waddled towards the front door. This close, Jon could smell Austin’s cologne, and Austin could smell Jon’s musk and meat breath. “What a great dinner, Sir,” Jon said as Austin fished his keys out of his pocket. “Glad you appreciated that, bull, you deserve it,” Austin said as he opened the door, Jon bending down to let him reach the keyhole. They entered, Jon turning sideways to fit both of them in, and kicked off their shoes. “Set me down,” Austin ordered and Jon complied, then straightened back to his full height, looking down at Austin. “Ever since you started growing, I’ve had these feelings,” Austin said as he stepped closer to his stepdad. “More than just pride or happy that we were coming together more after what happened to mom.” Austin planted his hands on Jon’s big pecs, the material of the new polo shirt smooth but damp from Jon’s sweat, and squeezed, massaging Jon’s huge chest. His fingers bumped against Jon’s big chain and heavy metal lock. “Mmmm,” Jon growled, “Me too, Sir. I—I had such an empty space in my life. As I dedicated myself to your desires, it just felt so good. So right. And I started to see the strong, handsome young man you’re becoming, and I—MMMMPH,” Jon groaned as Austin suddenly pinched his meaty, sensitive nipples through his shirt, causing the big man to squirm and flex his pecs. “Yeah, you started coming around, huh?” Austin said, teasing Jon’s nips some more. “It feels right to do what you’re told and obey your Sir, doesn’t it?” Jon breathed a heavy, shuddering sigh and nodded silently, staring intently at his master. Austin moved his hands lower until he got to where the polo didn’t cover Jon’s gut. Austin palmed Jon’s huge, round belly and bounced it up and down, the firm expanse of it furry and warm. “Like growing so big for me,” Austin said as he looked up at Jon, admiring his salt-and-pepper beard that came down to his chest. “So much bigger than me now, bull, quite the change from a few months ago.” “Y-yeah,” Jon said. He reached down and adjusted his huge bulge. “Did you like when I kissed you at the restaurant?” Jon said, sounding a bit sheepish. “I just couldn’t help myself.” “You mean like this?” Austin asked as he stepped closer until they were pressing together. He reached up and around Jon’s thick neck rolls and pulled his head down and planted another kiss. They made out in the entryway for over a minute, hands exploring each others’ bodies. Austin remembered the mirror in the entryway and turned them so they could both see themselves making out, finally fulfilling an unspoken desire that had grown over the last few months. They both groaned as they saw the size disparity, Jon half a foot taller and twice or three times as thick as Austin. Jon reached his hands under Austin’s shirt and felt his firm, furry abs, and Austin grabbed Jon’s enormous upper arms and squeezed. The big bull flexed them in response, Austin’s fingers spreading apart under the huge muscle. Finally they separated, both of them breathing hard, grinning and chuckling. “Jon, looks like you’re bigger all over,” Austin said as he looked in the mirror. He reached down and brushed a hand against Jon’s swollen package. Jon flinched and grinned, a shiver running up his bloated body. “Heh, yeah, I guess so…feels…” Jon started but trailed off as he reached down past his gut to squeeze his huge cock, causing his arms and shoulders and traps to flex. “Kinda good, right?” Austin said. Jon nodded wordlessly, gulping and breathing hard. “Why don’t you take your shirt and shorts off and show me how big you’re getting?” “Sure,” Jon breathed, his deep voice sounding strong but nervous. He grabbed the neck of his new polo and tore, and the wet fabric somehow still ripped apart easily, broken by Jon’s tremendous power. Austin had to help pull the sleeves past his bulbous biceps. His heavy chain clinked around as he took the shirt off. Then Jon stepped out of his shorts, the floor shaking as he did. All he was wearing now was a stuffed jock strap, which was stained from months of soaking up jock sweat. His massive balls poked out of the bottom and the outline of his massive cock head bulged obscenely. He adjusted his package and bounced it up and down for effect, admiring his own size in the mirror. “Jeez, Jon, you’re so… wow…” Austin said as he stepped forward and felt Jon’s enormous chest. The meaty muscle felt solid and heavy in his hands. Jon flexed, bouncing the pecs up and down to show off for his stepson. “You’re so big,” Austin finished as he rubbed Jon’s chest and across his bulging traps and bowling ball delts, tracing the lines of tiger stripe stretch marks. Smears of sweat made Jon’s blonde chest fur curl into ringlets, and Austin’s hands came away soaked with salty, musky sweat. His bullpup had grown so big, so fast. Jon just growled and purred as Austin explored his big torso. Jon looked at himself in the mirror and grinned, his now comparatively lean son worshipping his big, thick body; his cock got harder and harder, precum soaking the sweaty jock strap. “My big bull needs lots of attention and praise,” Austin said breathlessly, accelerating his rubbing, feeling the musclebear’s furry round shoulders, bulging biceps, and round gut. “Yeah, that’s right, and I’m just getting bigger and bigger, Sir,” Jon grunted as he raised an arm and flexed, causing Austin to feel the massive bicep. “You’re turning me into such a beast, Austin, just lifting and eating and feeling horny all the time,” Jon growled. “That’s right, my big horny beast, with a big package to match,” Austin grunted as he reached down and rubbed Jon’s cock. They rubbed and grunted for a minute, Jon feeling Austin’s lean body, which felt so good in Jon’s big hands. He looked in the mirror and saw something he never expected to see. “I never thought I was gay before… before all this,” Jon sighed as he ran his big hands over Austin’s muscular shoulders and arms. “I – I’ve never done anything like—“ Jon started before Austin shushed him. “This is what we’ve both wanted for months, haven’t you felt the tension building between us? And someone your size, with your muscles, who has worked so hard to grow so much, you deserve to feel good, you deserve your master’s full attention,” Austin said. He had Jon raise his left arm up before burying his face in Jon’s sweaty, hairy armpit, rubbing the dank pit sweat all over his nose, lips, and beard, licking and huffing the heady stink. “Yeah, you’re right,” Jon sighed, and reached over to press Austin’s head harder against his sweaty pit. “You like how I stink, don’t you?” Jon growled. Austin rotated and pressed Jon against the wall of the entryway; Jon looked down to see himself being worshipped by his jock son and everything felt so right. Austin came up for breath and grinned. “I’ve been waiting for this ever since I saw you were getting bigger,” Austin said, gasping for air, his left hand groping against Jon’s lat and gut while his other reached down to rub Jon’s hard, leaking cock. “I can’t hold back any more. You’re my big beast and I’m going to keep growing you bigger and bigger,” Austin breathed while he moved closer to Jon’s bearded lips. “And a big, hard-working musclebear like you deserves a master who treats him right,” Austin said before planting a hard kiss on Jon’s lips. Jon kissed back just as aggressively, making Austin lean back as the bigger man’s full weight pressed against him; they struggled back and forth over who was in physical control, and the tension made both of them hard. “Fuck yeah,” Jon breathed as they broke their kiss, his hands rubbing harder against Austin’s hard, muscular body, feeling the football jock’s firm shoulders, meaty chest, and big arms. “My hot little jock stud, turning me into a big daddy musclebear, treating me so good. I’d do anything for you, little Sir,” Jon rumbled. “‘Little Sir’, I love when you call me that,” Austin grunted as he pushed his brute hard against the wall again, Jon’s sweat leaving an imprint. “I need more from you. 500 pounds is big, but it’s just the beginning. And you need one more thing to eat today,” Austin said before reaching up to push down on Jon’s big traps. Jon dropped to his knees, the floor thumping as he did, and Austin pushed his shorts to the ground. His own cock, rock-hard, red, and leaking, bounced out of his boxer briefs and smacked Jon in the face. “Been waiting to do this since Thanksgiving,” Austin said. “Open wide, pup,” he commanded. Jon leaned down and slurped up Austin’s eight inches in one go. Austin gasped as his big, obedient stepdad started working his sweaty cock. Austin reached down and ran his fingers across Jon’s prickly high-and-tight, feeling the neck rolls that had grown over the last few months, then ran his hands over his pup’s chain necklace. This big brute was his, and now he was on his knees, his big head bobbing up and down rhythmically, servicing him. Jon wrapped his arms around Austin, gripping the football jock’s meaty ass in his big hands, and he sucked harder. “This is where you belong, pup, on your knees serving your master,” Austin said. He looked down and had a great view of Jon’s massive shoulders and traps, his barrel chest, and his massive arms flexing and bouncing as he gave the most intense blow job Austin had ever received. Jon grunted and slurped, sucked and growled. “You like it down there, huh?” “Mmmph, mmmm,” Jon hummed as he slurped up Austin’s long, hard cock. He looked up at his master, Austin’s thin chain necklace and golden key gleaming around his neck. His heart fluttered, their eyes meeting. “Fuck yeah, that’s a good muscle pup, slurp out every drop of my jock load and grow more,” Austin groaned as he leaned his hips against Jon’s beard and gripped his huge, hard traps. “You’re growing so big, so fast Jon, such a big freak, such a good pup, so good for your Sir aren’t you?” Austin gasped, getting closer to blowing his load. “Mmmmph!” Jon grunted as he sucked faster, the massive musclebear pleasing his younger master. Jon reached down to stroke his own enormous cock through his jock strap, pre leaking profusely. “UuunnnnghhUUUUGHHHHH,”Austin groaned as he came, filling his stepdad’s mouth with creamy seed. “Yeah, take it, pup!” Austin growled. Jon hungrily gulped down every drop, chugging it like a man in the desert who had finally reached the oasis. Jon licked his lips, swallowed whatever remained of Austin’s load, and looked up at his master. “You taste so good, Sir,” he said. Jon wrapped his arms around Austin’s legs and gripped his ass firmly. “Now it’s MY turn!” Jon lifted Austin up easily as he stood, throwing him over his shoulder, manhandling his smaller stepson and carrying him up the stairs and into his bedroom. He threw Austin across the room, who sailed farther than Jon expected until he landed roughly on the king size bed. “GODDAMN I’m strong now!” Jon said. He took a deep breath and flexed his chest, then reached up and rubbed the salt-and-pepper fur covering his pecs. “So BIG!” He grabbed the heavy chain and lock around his neck and pulled and flexed, his biceps and shoulders bulging with muscle, the metal clinking around. “Whoa there pup!” Austin said as his huge stepdad approached the side of the bed, waddling over and shaking the floor with heavy, purposeful steps. His cock tented the jock strap, soaked with precum. “Eager after all this build-up, aren’t you?” “Yeah!” Jon grunted. He was breathing heavily through his nose, his chest heaving up and down. “Take that jock off, I want to see your cock,” Austin said as he crawled over to the edge of the bed. Jon pulled the jock down until his cock was free. The massive, thick log bounced up and slapped against his huge musclegut. “Brrrooof, rrrruuuffff, mmmph,” he breathed as he stepped out of the jock and adjusted his heavy, tight balls. He squeezed his cock and a long drip of pre leaked down from the tip and onto the floor. He had to have been at least 10” long and as thick as a beer can. “Oh yeah, bull, look at this monster,” Austin said as he hefted his stepdad’s package and scooted himself to the edge of the bed. “A huge cock for a huge bull, huh?” “Rrrrrooofff, that’s right,” Jon grunted as he stepped closer. “You turn me on so much, Sir. Your tight, muscular body, your sweet cum, always taking charge and looking after me and my progress, giving me someone to serve,” Jon breathed as he loomed over Austin, looking down at him from over his barrel chest and round belly. “I need to give you everything, Sir.” Jon rubbed his bulbous cock against Austin’s cheek. “Need to grow so much bigger for you, Sir.” The BO stink from Jon’s bulging crotch filled Austin’s nose with a heady funk. “Yeah, that’s right Jon. Imagine how big you’re gonna be by spring break… or even graduation time!” Austin said. Jon’s cock bucked and twitched and leaked a dribble of pre down onto Austin as he thought about that. Austin reached up and squeezed Jon’s massive cock; he could barely get his hands all the way around it. “MMMMPH boooowwwrrruuff,” Jon growled. “How big do you want me to get, Sir?” “So big you outgrow all your clothes. So big you can’t fit through doorways.” Austin licked the head of Jon’s huge cock. “Grrrroooooff…” Jon sighed, bucking his hips and flicking his nips as Austin stroked. “So big you can’t live a normal life and have to let your little master take care of you.” Austin kissed the cock head, wrapping his lips around it briefly. “Uuuuurrrrffff, grruuuuff!” Jon growled, his deep booming voice rumbling above Austin’s head. “My big trophy musclebull daddy pup. You want that?” Austin said, squeezing and stroking Jon’s cock. “Aaaroooooooofff!” Jon breathed. “Then give me your seed, pup,” Austin said as he opened wide and slurped up his stepdad’s massive cock, struggling to fit it in, gulping and choking and gagging until the entire cock was in his mouth. Jon groaned as pleasure washed over him. He reached down and gripped his stepson’s head in his huge, calloused hands and roughly pressed him against his massive tool. “Fuck yes, Sir, take your bullpup’s big cock,” Jon groaned as Austin bobbed against his cock. “Baaarrroooooff!” Jon looked down, past his enormous pecs and forest of chest hair which hadn’t been there 5 months ago, past his round, solid, furry gut which pressed against Austin’s forehead, down to the sight of his dominant jock stepson slurping a load out of him, and he was overcome with emotions. Jon grunted and growled in a haze of animalistic lust, slamming into Austin’s warm mouth and throat, months of pent-up sexual pressure overflowing out of him. “Fuck yeah, so fuckin’ huge, growing BIG for you Sir, YEAH!” Jon boomed as he got into a rhythm. “Just imagine how much BIGGER I’m gonna get, all for you, Sir, GRRRROOOOOOF!” Jon paused and pulled out, leaving Austin gasping and drooling, then reached down and grabbed his stepson under his pits. He pushed forward, scooting Austin onto the bed, and climbed on top of his smaller Sir. His massive thighs straddled the big football player easily, and he leaned down and forward until his huge cock pressed against Austin’s lips again. “Yeah pup, show me your true size and power, fuck my face,” Austin said as he opened wide. “Uuunnnfff, uurrrff,” Jon breathed as his battering ram cock invaded Austin’s smaller, tight mouth. “So big, GGRRRFFF,” Jon groaned as he squeezed Austin’s comparatively small torso with his 38” thighs, pressing his 500lb weight down onto his stepson as he started thrusting and humping harder. Jon looked down, his helpless master greedily slurping up his cock, eager for his bull pup’s thick cream, and pictured himself rising taller, bigger, wider, thicker, his muscles expanding harder and huger until he couldn’t even fit into this room and he felt his balls twitch and tighten. “YEAH, TAKE YOUR DADDY’S LOAD, Sir, UHHHHFFFRRRAAHHHH,” Jon roared as he exploded, the biggest load he had ever shot. Austin eagerly gulped up all of his stepdad’s potent, thick seed. When he was finished, he leaned back, cum and saliva dripping off of his cock. Austin coughed and sputtered, then reached up and rubbed the massive furry gut and muscular chest looming above him. Jon shifted his weight off his master and then moved around until he was spooning Austin, the mattress groaning as the 500 pound man shifted his weight. “Mmm, amazing,” Jon sighed. He reached a big arm around Austin, who pressed perfectly against his beefy side, tucked against his sweaty pit. Austin’s head rested on Jon’s enormous right pec. He could feel Jon’s warm breath and hear his heartbeat, still elevated. “My big bull, such a good pup,” Austin cooed as he rubbed Jon’s furry chest, lingering over the heavy metal lock and chain that lay against Jon’s chest. “And now we have all Christmas Break to spend time together,” he said. “That’s right,” Jon said. His enormous cock twitched and lurched, ooze smearing across his big thighs. “We can do all kinds of stuff together.” “Uh huh. Are you gonna be a good bull and lift with me?” Austin said, whispering in his stepdad’s ear. “Yeah,” Jon said in a ragged whisper. His cock twitched, already bulging longer even though he had just cum. “And cook for me and eat as much as you can?” Austin said. “Oh yeah,” Jon growled. His balls tightened. “And take care of all your master’s needs?” Jon’s cock bulged fully hard, all the way up to his deep belly button. He leaned down and kissed his little master on the forehead. “Of course, Sir,” Jon said obediently. “Good pup,” Austin said, who reached over and started stroking Jon’s thick cock. “Good.”

Previous chapters: Chapter 1 Chapter 2 Chapter 3 Austin comes home for Christmas Break to see how much bigger his musclebear step dad has grown. Jon shows off his new size and strength, and the two continue to grow closer together. Chapter 4: Christmas Break Austin pulled into the driveway of his dad’s house, the snow crunching under the tires of his big truck. His stepdad’s own new truck, which was even bigger than his, sat in the driveway. It was a bright and sunny afternoon, but cold with snow all around, a lovely white Christmas as Austin arrived home for winter break. Austin knew that if Jon had been following his regimen, he would be napping now. Austin had given Jon a strict schedule and routine to follow, down to the hour, and had worked hard to order food, supplements, clothes, equipment, and more since going back to college after Thanksgiving break. He had really stepped up Jon’s growth and training, sending over food deliveries every day and even supplying him with growth hormones and steroids. Austin wanted to maximize this opportunity to make Jon grow as big as possible, whatever it took. He had also told Jon not to give him regular updates on his progress; Austin wanted to be surprised how much Jon had grown over the last 4 weeks. Austin quietly opened the door, making his way into the house through the front door. He sniffed deeply as he came inside; the whole house smelled like a locker room, sweaty and musky, but he also smelled freshly-baked cookies. He could see a stack of recently-eaten plastic food containers and a decimated tray of gingerbread cookies; Jon had a big lunch, just like Austin told him to. “SSNNNNRRRRHHHH… Hhhhhnnnngggg.” Even from the entrance, he could hear the deep, rumbling snores of his big muscle pup stepdad from the bedroom upstairs. He made his way there quietly, taking off his jeans and jacket and getting down to his tight boxer briefs and tank top, his bullpup’s snores getting louder as he got closer, the musky jock stink getting stronger as he opened up the door to the bedroom. Inside, Jon lay sprawled out on the bed under the covers, a mountainous, ursine form rising and falling with each thunderous snore. Austin could see his face, his cheeks fuller and plumper than when he had last seen him, his mouth slightly open, drooling in total relaxation. His beard was thick and luxurious, waves of brown, blonde, and white fur filling out and down. Austin approached and carefully got into bed, nestling in under the covers next to his massive dad, letting Jon be the big spoon to Austin’s little spoon. The temperature and humidity under the covers was intense, and Austin immediately started sweating; Jon’s body was radiating heat like a furnace. Jon, still asleep, breathed in deeply and then exhaled, his warm breath washing over Austin as he smacked his lips. Jon adjusted his weight and wrapped his arms around the warm, firm mass he had suddenly found pressing against him. Austin felt his huge pup’s bulge under the covers swell to life, twitching and growing as it strained the tighty whities that contained it. It throbbed until it pressed firmly against Austin’s furry, muscular ass. Jon bucked against him in his sleep. Jon’s breathing became more erratic as his cock grew even bigger, and his arms suddenly squeezed Austin tightly; his strength was unbelievable! Austin grunted as Jon’s bulge pushed right against his tight hole, teasing and threatening to invade, until Austin managed to twist around in his pup’s grip and face him. “Hey there, big pup, guess who’s home?” Austin said as he reached out and felt Jon’s enormous chest under the covers. Jon was shirtless under the covers, and his pecs were slick with sweat. His dense chest fur curled into ringlets as Austin rubbed. He couldn’t see it yet, but the amount of mass under there made him gasp; just how big had his daddy pup grown? Jon awoke, the ice blue of his eyes sparkling and a massive smile spreading across his face. “Sir!” his deep voice boomed, vibrating Austin’s torso with the force of it. “You’re home already!” Jon squeezed Austin in his massive arms, the muscles of his biceps pressing against Austin’s sides until he almost felt ribs popping, his breath smelling of chocolate protein powder and chicken. “MMM, I’m so excited to see you!” Jon said, bulge rubbing against Austin’s under the covers. “Hhhhnnggg, pup you hug so hard!” Austin wheezed, feeling the air press out of his lungs. “Merry Christmas, dad!” Jon grinned wider. “Heh sorry son, I don’t know my strength!” Jon adjusted his weight, causing the bed to shake, and rubbed Austin’s lean, hard abs and sides under the covers, running his huge hands up and down his master’s torso. “Mmm we could cuddle in bed like this all day,” Jon purred. Austin noticed that his voice was even deeper than it was at Thanksgiving. “I missed you so much,” Jon whispered as quietly as his deep voice would allow, emotion causing his lower lip to quiver a bit. “Aww, big guy, I missed you too,” Austin said, rubbing his hands across his stepdad’s bigger, thicker body. He leaned in closer until they were face to face. We’re gonna spend so much quality time these next two weeks,” Austin whispered. Both of them breathed in deeply and sighed, feeling excited and relieved to be together again. “Mmm, sounds good, sir,” Jon said as he stretched and flexed his huge body. “We should keep cuddling like this, I missed this the most,” he said as he wrapped his big arms around Austin’s smaller body. “We could, but then we’d miss valuable opportunities for you to grow! And I think it’s almost time for your afternoon lift, isn’t it?” Austin said. “Have you been a good pup and following Sir’s schedule?” “Of course, Sir!” Jon said, sounding more serious. “Your schedule is perfect. It’s really been helping me grow BIGGER,” Jon said. “Plus, I’m already getting hungry again, almost time for me to feed.” Austin slipped out of Jon’s arms and scooted out of bed. Jon’s eyes lit up and scanned Austin’s lean, muscular body as he stood next to the bed. “Like what you see, pup?” Austin said, showing off his fit, muscular build, flexing his hard pecs and trim waist. He was college muscle jock perfection. “Yeah, Sir, you look great,” Jon rumbled as he shifted off the covers, planted his feet next to the bed, and stood slowly. “But you’re so much smaller than me now!” Austin took a step back, his jaw dropping open, as his stepdad rose to his full height. He was way taller than Austin’s 6’0” now. Austin stared straight at his dad’s chest, then craned his neck to look up at the brute smirking down at him. The floorboards creaked as Jon shifted his weight and took a deep breath, expanding his massive chest in Austin’s face, the thick musculature of his pecs swelling to full size. Jon exhaled, his breath ruffling Austin’s hair, and grinned. “Heh, little master looks smaller than last time!” Jon rumbled, standing nearly naked in front of Austin. His immense torso heaved with thick muscles as he breathed in and out. His calves and thighs bulged outwards, great mounds of muscle to hold up his titanic torso, and pushed his obscene bulge forward. Jon was slick and shiny with sweat, like he had just lifted even though he was napping. Austin noticed the sheets were soaked and stained yellow from Jon’s constant sweating, a side-effect from his unprecedented growth, and the full strength of his BO funk washed over Austin in waves of sharp, sour musk. “I don’t think I’ve gotten any smaller, but you certainly have grown a lot bigger!” Austin said as he breathed in his dad’s musk and rubbed his hands against Jon’s huge, broad chest. Jon stepped forward and bounced his belly against Austin, causing him to take a step back. “I’ve been growing really fast since Thanksgiving, Sir,” Jon breathed and he brought his fists together in front of his gut to flex. His round, thick chest, mountainous traps, and bulging biceps all swelled with size, so much bigger and thicker and harder than just a month ago. “Usually 7 or 8 pounds a day. Is that good?” Jon said innocently, pressing harder against his hard, lean, muscular stepson. “Jon you’re… so much bigger! How is this… wow!” Austin stammered, feeling his stepdad’s bigger, stronger, thicker body. “Just following your directions, Sir. Eat, lift, eat, nap, eat, lift, eat, lift, eat, sleep,” he said, counting off each step with a finger. “I need to work hard to grow big for you, son. Are you proud of me?” Jon said as he stepped closer again, backing Austin up against a wall. Jon pressed his belly and chest against Austin’s torso and face. “Do you like all my gains? It’s all for you, Sir…” Jon said as he started to rub his sweaty bulk against Austin. “Love growing bigger for you…” Jon’s cock had grown along with the rest of him, and the sweaty, stained underwear strained to contain it; it swelled as Jon rubbed against Austin, pre forming a wet spot on his underwear. Jon shuttered as he felt his bulk pin Austin to the wall. “So much bigger than you now…” Jon breathed, his balls tightening, and Austin could feel his barely-contained bull strength physically and mentally overpower him. Austin pushed back, his will overtaking Jon’s. “No, pup, not yet. We still have more work to do before we can have fun!” Austin said forcefully. “Yes Sir!” Jon growled, his deep voice booming. “It’s time for your afternoon lift, pup. Let’s get to it. This time with your little master pushing you to your limit. Let’s see what this big body of yours is capable of!” Jon smacked his fist into his palm, flexed his chest, and grunted. “Yes Sir!” “Step over to the scale and let’s just see how big you’ve gotten,” Austin said, and Jon obeyed. The scale was a big, industrial-strength one for measuring freight; Austin had purchased that knowing they would need it in the months to come. The number flashed 504 when it had equalized. “Over 200 pounds in 4 weeks! I’m so proud of you, pup,” Austin said, rubbing his hand against Jon’s wide, muscular back. “Getting SO big, pup!” “Mmmph, yes Sir, growing bigger for you!” Jon said. His whole body shivered with pleasure and his big bulge twitched. Nothing pleased him more than hearing his Sir praise him. “Step over to the mirror,” Austin ordered, and his pup obeyed. Austin noticed the hardwood in front of the mirror was stained white and yellow, and dried, milky streaks dirtied the mirror itself. “Stand up straight,” Austin said as he walked around his hulking stepdad, inspecting the growing specimen. Jon’s shoulders bulged out to the sides, his arms pressed against his thick lats, and his back spread wider than two regular men. His waist narrowed and looked trim against the absurd width of his shoulders, but his round, hard gut swelled out in front, matched only by the thick pec shelf that hung above it. Jon’s beard had grown longer to the point where it was brushing against the dirty blonde chest fur, which was coiled in sweat-soaked ringlets that covered his giant pecs. The beard had a bright blonde streak running down the middle, flanked with darker, denser fur that covered all the way up to his ruddy, full cheeks. His hair was freshly trimmed, just like Austin had asked for. More fur spread along his traps and shoulders and inched down his back; it was growing thicker back there quickly. The giant shifted his weight, his massive 500lbs causing the floor to groan, and Austin saw how his enormous thighs twitched and swelled to support his mass. “Good, bull. My, my you’re getting big, aren’t you?” Austin said. “Y-yes Sir,” Jon said, enormously turned on, his hard cock throbbing and leaking as he looked at his own reflection, his muscles twitching with every slight movement. “How do you feel about your growth and progress, pup?” Austin said, teasing the big man further, running a hand over the immense, dense expanse of Jon’s upper right arm and bulbous, round, hard deltoid. Jon instinctively flexed for his master. “G-good… big! So much growth… all I do, Sir, I lift, I eat, I sleep. I can’t think about anything else but MORE, Sir. I want it so badly,” Jon groaned, even more so when Austin ran his hand against Jon’s bulky pec and flicked a meaty nipple. “Good. You’re a good pup, aren’t you? Always listening to me,” Austin said as he circled around his enormous stepdad, rubbing his calloused hand against Jon’s enormous, thick bubble butt and bouncing it up and down. Jon sighed, his body shaking. “Yes Sir, always Sir, of course!” he said, trying to sound tough but his voice wavering, his mind overcome with desire. “Anything for you!” “Mmmm good,” Austin cooed. “But is this enough?” he said, reaching up to pull Jon’s ear down to him. “Or do you want more?” Austin said, the last word a breathy whisper that lingered. Jon shuddered instinctively, his cock twitching, his muscles shaking. A thick strand of precum oozed out of his hard cock and made a growing wet spot on his briefs. “Unnnggg, Sir, I need…” he trailed off, before taking a heavy breath and gulping, suddenly thirsty. “I need MORE!” “That’s what I want to hear,” Austin said, still holding Jon’s head to lean down to his height. “Now get dressed and show me what you can do with all that bulk,” he said as he released his pup and smacked his ass hard. Jon grinned and straightened to his full, towering 6’8” and 504lbs. “Yes Sir!” he boomed as he flexed in the mirror for his little master. “LET’S GOOOO, PUSH, NOW!” Austin yelled in a commanding voice right in Jon’s face, squatting down in front of his massive stepdad. “FUCKING NOW, PUP, DO IT!” Jon grunted loudly as he stood from deep in the pocket. A thick Olympic bar with enough weight on each side to make it bend lay across his enormous traps and shoulders as the huge man stood, slowly but surely. His quads quivered as he did, shaking with power and exertion. “RRRRHHHHUUUUUHHHHH,” Jon growled as he stood to his full height, the weights shaking as his legs flexed, holding over a thousand pounds on his back. He had just finished another set of 12. “FUCK YES, BULL!” Austin said, slapping his huge dad on the back as Jon unclasped his belt and breathed heavily, his chest heaving up and down. A puddle of sweat pooled underneath him as it dropped off his face and arms. He bent over to catch his breath, grunting and shaking, adrenaline surging through his veins. Jon was wearing black gym shorts that only came halfway up his thighs, which were ruddy and swollen with pump, and a stringer tank top that was a shade darker than it ought to be from sweat, a mascot logo of Austin’s school on the front, faded from overuse even though it was just a couple months old. It was comically small for the big man. The look was completed by huge, wide, heavy Otomix shoes, the flat bottoms perfect for lifting heavy, the laces open to make room for Jon’s thick feet. “Four hours of hard work and grinding and showing your Sir what you’re capable of,” Austin said, leaning down and speaking into his dad’s ear. “And you know what?” Austin asked. “Huuhhh, ffffuhhhh, mmmmuuaaaahh, what,” Jon gasped. “You’re the biggest,” Austin said, punctuating his words by slapping his dad’s meaty ass, “strongest,” *smack* “thickest” *smack* “hardest working,” *smack* “bullpup I’ve ever seen,” Austin said, ending by grabbing a handful of Jon’s thick glutes and squeezing. “Hehe, *huff*, thank you, Sir!” Jon panted, standing and putting his hands on his hips, pacing around and shaking out his overclocked quads. “Couldn’t have done it *huff* without you pushing me.” They were just wrapping up a 4 hour long marathon gym session. The garage had been further upgraded into a world-class gym, way bigger and better than the old set up a month ago. They had done a little bit of everything, Austin ordering Jon around and pushing him harder than ever, yelling at him, spotting for him, keeping him going harder and harder. Jon was eager to show off for his stepson too. He had worked so hard over these months, mostly alone, feeling the need to make his son happy and proud of him, needing to grow bigger and stronger. Now that his master was here in person, pushing him harder, that desire consumed every thought in his mind. To do so in front of him now, achieving results he never dreamed possible, was extremely fulfilling. “I’m so proud of you, pup. You know, you are easily the strongest man in the world now,” Austin said, coming up to his sweat-soaked stepdad and wrapping his arms around him. He could only reach to his lats, not even able to reach his back now. Sweat dripped down on him from Jon’s beard and nose. “Absolutely crushing world records in front of me like it’s no big deal,” Austin said as he looked up at his obedient pup. Influencing him like this felt so easy, so good in person. Jon grinned as he looked down at Austin. He took a deep breath and expanded his chest, making Austin’s arms lose their grip around his lats. He swelled with pride, and his cock bulged in his shorts. “All for you, son. Turning into the biggest damn stepdad in the world!” Jon said. He lifted his arms up for a double-bicep pose. “Mmm that’s right,” Austin said, reaching up to caress Jon’s massive arms, which were covered in a slick sheen of sweat. The musky jock smell that radiated from Jon’s pits hit Austin like a wave, intense and tangy and manly. The whole room was hot and humid even though it was winter outside. “And you smell so good,” Austin said. He stepped forward and buried his nose in Jon’s deep, hairy pit. “Mmm glad that you like my scent, Sir,” Jon grunted, pup said with a smirk. He lowered his arm, trapping Austin in his musky armpit. “Yeah, getting my man smell all over you, mmm,” Jon grunted. Austin gasped as he came up for air, snuffling and looking dizzy. “Hoo, wow, that’s good,” he said. “Such a musky pup! Makes sense with how hard you’ve been working and how big you’re getting, huh?” Austin teased. “All the gear I’m on makes my musk smell even more potent, Sir,” Jon rumbled. He cranked his neck over to his hairy pit and huffed deeply, breathing in his own musk. He exhaled and then took another whiff, his muscles straining, hard for him to move his nose over that far now. “So good, rrrfff,” Jon sighed. “Now go pump up those pecs some more,” Austin said, pointing to the pec deck. Jon obediently complied. “I’ve grown so fast… it’s almost hard to believe,” Jon said as he lowered his arms. He waddled over to the pec deck, which was already set at the highest weight, like all the machines were. “I’m a new man, a bigger, better man! And I just keep growing… I keep wondering if it’s going to stop or slow down, but if anything I’m just growing faster every day. It’s an addiction. It’s all I think about. And all for you, son,” Jon grunted as he started cranking out reps. “I know,” Austin said, walking over to Jon and watching him pump his chest, each rep more than what Austin weighed. “I never expected this. I wouldn’t believe it if I didn’t see and feel it myself,” he said. 20, 30, 40 reps without a rest…Jon made it look like warm up weight. Jon’s pecs swelled up fuller and bigger; Austin reached out and felt Jon’s chest hardening and squeezing with each rep, rubbing the sweat that ran down Jon’s pec cleavage. “Feels amazing, pup,” Austin said as he rubbed. Austin looked right into Jon’s blue eyes. Jon stared back, both of them locked in. “And you’re just gonna keep getting bigger, I can feel it.” “It feels, unf, so good, Sir,” Jon grunted, passing 50 reps. “I never knew how badly I needed to grow. I’m so glad, unf, I have you to guide me. And, unf, how much size I keep packing on. And how much, unf, taller I’m getting! It’s awesome. I, unf, wake up every morning in awe of my own, unf, GAINS, and it’s all because of you, son,” Jon grunted, perfect rep after perfect rep making him sweat profusely. “Of course, dad,” Austin said. “Anything for my growing pup. Your growth is beyond anything I ever dreamed of. When I told you to get into lifting 4 months ago, I never realized I’d be creating a MONSTER,” he said. Jon finished his 100th rep, looking like he could have gone for another 100 even though he had been lifting unreal weights for 4 hours. The weights clanked back into place and the big musclebear daddy stood to his full height again, towering over Austin. “Mmmmm I love when you call me that,” Jon growled, his deep voice rumbling Austin’s chest. He adjusted his weight, his pumped chest pushing out between his flimsy tank top. “Monster grow big for master,” he grunted in a goofy, goonish voice, his eyes glazing over, his obscene bulge throbbing in his tiny gym shorts. “Such a good pup,” Austin said, stepping forward and rubbing Jon’s huge chest. “And such a handsome one too,” Austin said. He looked up and let his hand move up to Jon’s beard and he held his hand against Jon’s cheek. “It’s so good to be here with you in person again, pup,” Austin said, locking eyes with Jon. “I’m such a lucky master.” Jon took a deep, shuddering breath. It had nothing to do with his long workout. He gulped heavily, anxious and excited. “Yeah Sir, I feel the same way for sure,” Jon said. His cock throbbed as he pressed against Austin’s firm torso, so lean and hard. “I’m the lucky one!” Jon said. He ran his big hands up and down Austin’s torso, feeling his youthful frame and firm muscles, and closed his eyes, overwhelmed by what he was feeling. He bent his head down so Austin could rub the side of his face and head more. He opened his eyes again and stared as Austin’s face; a short beard, a strong jawline, and glittering green eyes. “You’re so hot, you know that?” Jon sighed, feeling relieved to admit that. “Heh, thanks dad,” Austin said as he scratched and rubbed his stepdad’s beard affectionately. “That means a lot coming from, stud,” Austin said. “And just think, we have two whole weeks of this.” Jon sighed contentedly and wrapped his arms around Austin. They held each other like that for a full minute, breathing each other in, feeling each others’ heartbeats. Finally, Austin pulled away. “Let’s finish with a big arm pump, hmm?” Austin said and pointed to the tricep pulldown machine. Jon just grinned and nodded. Jon waddled over to the machine, wrapped his calloused hands around the rope, thrust his chest out, and started cranking out perfect reps, the entire weight rack flying up and down like it was nothing. Jon huffed and growled with each rep; his rumbling, guttural grunts made him sound like a prized bull. Austin stepped closer and felt Jon’s enormous right upper arm hardening and flexing with each rep. “Yeah, you like getting bigger huh? Feels good to pump up these big arms for me?” Austin said, rubbing the sweaty mass of his stepdad’s tricep. The upper arm was unbelievably big, dense, and hard. Austin wondered if it was bigger than his thigh yet. He knew it would be sooner or later. Jon grunted louder as he passed 50 reps, his chest thrust out with a fresh pump, straining the pathetic straps of his too-tight tank top. Fresh waves of musk wafted out from his pits with every rep. “It’s – mmmph – really intense having you – rrrfff – here with me as I – ggrrrph – lift and get bigger for you – uuhhhff – Sir,” Jon grunted as his triceps pumped up more and more. His bulge, already obscene in his sweat-soaked gym shorts, tented considerably as Austin rubbed his arm. “You like it?” he groaned as he slammed the weight back down after his 100th rep. Jon flexed hard, the definition and raw bulky size popping out even more. “You think I’m bigger than before?” he asked, his eyes desperate for approval. “Oh yeah, pup, so much bigger. Now finish up with some curls in the mirror,” Austin said, leading the bigger man over to the rack of dumbbells. They were all custom ordered and went all the way up to 200lbs. “Grab those 100s. There you go. Now, shoulders back, elbows locked in, I don’t want to see any swinging. Good,” Austin said, directly his bull into perfect form as Jon started cranking out reps. “Give it a good squeeze and pause at the top of the rep, feel that mind-muscle connection.” Austin said, and held his hand on the hard peak of Jon’s left bicep. “Like this?” Jon said, staring at himself in the mirror, making sure his form was perfect, eager to please Austin. His upper arms, which had to be 25” at least at this point, bulged in a rhythmic, almost mechanical precision, each rep perfect, each rep making his arms expand even bigger. Jon’s bulge tented even more as he noticed that the size difference between the two of them was even more dramatic than it was a month ago. He was getting so big, just what Austin wanted, and nothing made him feel happier than that. “Perfect,” Austin said, squeezing the huge bicep. “So big, bull pup. Pump ‘em up more. Push through the pain. Get to 100 reps for me, come on!” “Grrruuuuhh – MMMpphhh – UUHHHHPH!” Jon grunted louder and louder as he cranked out 100 perfect reps, filling the garage with guttural groans, sweat dripping off his face and elbows and onto the floor mats below, his eyes locked onto the mirror. Finally he dropped the weights, which thunked to the floor. He turned to Austin, raised his arms, and flexed, showing off his hard-earned mass. “MMMphh, how’s that, Sir?” he groaned as he flexed, sweat dripping everywhere, his clothes soaked, his furry pits and chest radiating heat and musk. “Good! Big!” Austin said, smacking Jon’s big arms. “Now it’s time to reward you for your hard work.” Austin pulled out a package he had been hiding nearby and he unfolded it. “4XLT was the biggest they had in stock, so I made sure to get that. But I think you may have exceeded even this size, stud,” Austin said as he held up a brand new polo shirt with his college’s logo as the chest patch. “Mmmm I love it,” Jon said. He gripped the neck of his old tank top and tore, the shirt easily peeling in half down the middle, yielding to Jon’s power. “Thank you, Sir,” the musclebear growled. “Put it on now, even though I know you’re going to soak it with bear sweat. We’re gonna head to the doctor now to get you checked out, and then it will be time for you to feed, huh?” Austin said as his bullpup struggled into the shirt. “Need some help there?” “It’s… I can’t get it on,” Jon grunted as he struggled to wrestle the shirt on over his head. His range of motion was limited from his massive pump. “Here, pup, let me help,” Austin said. “Poor guy, too big to fit into clothes. Better get used to that,” Austin teased as he helped adjust the shirt, yanking it down over his dad’s sweaty back and thick trunk. “Grrrrr soon you’ll run out of things that fit me, son,” Jon mused. He stood to his full height again when the shirt was finally on. “Haha, Jon I think you might be too big for 4XLT already,” Austin said, trying not to laugh. The shirt was stretched taut across his broad chest, each pec straining the fabric. The sleeves stretched across his massive arms, barely hanging on and cutting into his beefy biceps, constricting them a bit. The neck hole was too small and threatened to choke Jon until he reached up and ripped it a bit wider. Most noticeable of all, the shirt only came down to Jon’s belly button, struggling to cover the huge, round belly of the big musclebear. A sliver of furry powerlifter tummy protruded from the bottom, like dough popping out of a can. “Doesn’t fit, Sir,” Jon said with a smirk, then raised his arms to flex. His biceps rose into thick, hard peaks. The sleeves pressing harder and harder against the massive muscle until they ripped simultaneously with a dramatic snap sound. “Heh, yeah!” Jon chuckled as he checked out his newly freed biceps and pumped them a couple times. He speed his lats wider, and his shoulders and traps bulged with power. The shirt strained to contain him, and it rode up even higher on his belly. He lowered his arms and laughed, the shirt staying stuck on his sweaty chest and belly. “Heh, I think it’s perfect, pup,” Austin said and rubbed his stepdad’s round gut. “I think everyone is going to know how big you are when you wear this, including the doctor. And then we’re going to go out and get a BIG dinner, my treat,” Austin said. “Mmmm sounds amazing,” Jon hummed, relishing Austin’s belly rubs. His cock thickened and swelled at the touch of his jacked, dominant stepson, tenting in his short, black gym shorts that revealed his massive quads and bulbous calves. “So hungry,” he said, and on cue his huge belly rumbled loud enough for Austin to hear clearly. “Well I’m gonna make sure to fill you up GOOD,” Austin said. “Let’s see how much you can pack away now that you’re even bigger!”

Previous chapters: Chapter 1 Chapter 2 Austin comes home for Thanksgiving Break, and Jon has grown much bigger. Austin cooks a huge Thanksgiving feast for his stepdad, who is eager to impress his stepson. Jon and Austin's relationship continues to evolve. Chapter 3: Thanksgiving Break The garage door opened, and the morning sun crept in slowly, revealing an elaborate, fully-featured home gym. The light spread, revealing a bench next to a rack full of weight plates, a squat rack with a loaded barbell, a set of heavy kettlebells, a multi-use cable machine, and a full row of dumbbells that went all the way up to 150lbs. The walls were lined with full-length mirrors, and mid-90s rock blared from the speakers installed in the upper corners. Standing in the back of the garage, wearing a sweat-soaked tank top, completely focused on his set of heavy preacher curls, was Jon. Austin rolled his big truck into the driveway and got out, admiring the good work the installation crew he hired had done to set up the home gym. The football season freshly completed, Austin was at his peak fitness, the biggest and best shape he had ever been in at 6’0” and 240lbs, heavier than he probably should have been at his position of quarterback but he loved the size. And he couldn’t wait to see how much bigger his dad had become. He couldn’t see him yet, as Jon was behind the cable machine at the back of the garage. Over the loud music Austin could hear the weights shifting and Jon’s deep grunts. “Mmpph… Rrrffff… Uuunnfff… Hrrrfff…”, getting louder as Austin walked past a barbell loaded up for deadlifts with 400lbs of plates on it. “Huuuffff…Mmmph…Uuahh…,” *CLANK* Finally winding past the cable machine, Austin gasped and dropped his bag as he approached Jon from the side. Jon stood up from his preacher curls to his full height, bringing his fists together and flexing his arms in the mirror. Massive, pumped biceps bulged with muscle, the length of his arms slick and shiny with sweat. His tank top was comically small; it only covered his sizable gut down to his belly button, the material creased and strained over his wide shoulders and chest, and the straps were pulled taut against his mountainous traps and huge pecs. Wide, burly shoulders were capped with thick, hard-looking traps. Huge, meaty upper arms trailed down to equally impressive forearms. Jon’s legs were big too. Austin noted that every single muscle group of his once-diminutive stepdad was easily bigger than own. “Dad?” Austin said, hardly believing how much bigger Jon had become since he had last seen him. Jon turned to his stepson and a huge smile broke out on his face. “Austin! Hey, you’re here earlier than I thought and I was so locked in I didn’t notice you coming in,” Jon said as he stepped out of the preacher curl set up and spread his arms to bring Austin into a big bear hug. Austin noted with disbelief that he had to look up to meet Jon’s gaze now; Jon had somehow grown taller. “Grrrrrr haha you’re looking great, son!” the big bear growled as he clamped his arms tight around Austin’s waist. He leaned back and lifted all 240lbs of him clean off the floor. “I’ve been lifting since 6am, I was so excited to see you I couldn’t sleep!” “Huuuu jeez dad, you’re so…” Austin started but the air was squeezed out of his lungs as his big stepdad bearhugged him. Austin could hardly believe Jon’s strength; he could feel it in his big hug, harder than anything he’d felt during the football season this year. Jon’s sweat-soaked body rubbed against his stepson, getting Austin’s shirt wet. Jon relented and put Austin down. “Jesus, Jon, fucking look at the SIZE of you!” “Hehe, yeah? Am I bigger?” Jon said modestly, bringing a big arm up and scratching the back of his head, which caused his massive upper arm to flex and bulge with muscle. “I guess I’ve been growing some the last few weeks.” His voice was noticeably deeper than a few weeks ago. He dropped his hands down to grab the hem of his shirt and lifted it up to wipe the profuse sweat dripping down his face, exposing the massive hairy belly and chest underneath. Jon dwarfed Austin, the 21-year-old realized; wider, taller, thicker, just fucking bigger all over! His eyes swept up and down, hardly believing the size and rapid growth of his 42-year-old step father. “Flex your arm,” Austin commanded, and Jon did, curling his big arm down towards his belly and flexing hard, his shoulders surging, his upper arm swelling with thick muscle as it pressed against the side of his thick pec. Austin reached out to feel, his fingers small over the expanse of his stepdad’s huge, hard bicep. It throbbed and felt warm to the touch; a big blue vein pulsed down the middle of it, leading to a network of them that could be seen under the blond hair of his thick forearm. “21 inches as of yesterday, getting hard to measure myself though,” Jon said as he lifted up his other arm, bringing it into a big bicep flex. A wave of intense, musky BO washed over Austin from the sweaty, hairy armpit. “Well maybe I can help you out with that later this weekend, you big galoot.” Austin smacked Jon’s beefy shoulder and nodded. “Wow, your progress is even more spectacular than I was expecting. I’m so proud of you, dad,” Austin said and he squeezed Jon’s shoulder, feeling its size and hardness. “You’re really turning into a big, strong musclebear daddy, aren’t you? And you love it, huh?” Jon said, stepping closer and putting his hands on his dad’s big chest, smacking his sweaty pecs. Jon grinned and squeezed his chest, letting Austin feel the hardness and size of his pecs. “Uh huh, I love it,” Jon said, enjoying the feeling of Austin’s calloused hands rubbing his chest. Jon’s big cock chubbed up in his gym shorts, pressing against the tight jock strap for space. “Growing so big for you, son,” Jon said dreamily. “Mmmmm, good,” Austin purred. “Let’s step over to that scale and see just how much bigger you’ve gotten since I’ve been gone.” As they walked over to the scale, Austin noted that Jon was indeed taller than him now… how was his dad growing taller in addition to growing so fast? Austin decided to return to that question later. The scale clanked and groaned as Jon stepped on, his high tops taking up most of the room on the scale, which rattled around until it leveled off. “290!” Jon said proudly. “How’s that for you, son?” Austin patted the big bear on his wide back, admiring how his lats stretched the fabric of the tank top. He pulled at the fabric and laughed at how tight it was. He rubbed his hand over the damp upper back. “It’s unreal, dad, just amazing. 70lbs in 6 week!? You’re a monster! My big growing bull,” Austin said, rubbing his hand harder on Jon’s neck, causing the big guy to growl. “Told you that you would outgrow these XXLs, didn’t I?” Austin said. Jon was wearing the one with the big, buff mascot on it. Even though it was only 6 weeks old, it already looked worn, faded, and sweat-stained under the pits. Jon stepped off of the scale and they headed into the house, Austin closing the garage door as they did. A trail of fresh, funky BO followed Jon where ever he walked, and Austin breathed it in like a perfume. “Yeah, I’ve been doing what you said, I wear them every time I lift. I was washing them after each lift at first, but it started feeling pointless to wash them so often, so I don’t anymore. Haven’t washed this one in a couple weeks, I think,” Jon said as they walked to the kitchen. Jon’s walk had changed into more of a waddle, his huge thighs rubbing against each other, his wide shoulders swaggering back and forth as he did. Jon reached up to grab a clean shaker bottle from the immaculately organized and cleaned kitchen – Jon had followed Austin’s directions there too – and started making his post-workout protein shake. “Yeah I can smell that, bull, when’d you last take a shower?” Austin asked. Jon shrugged, his big traps bulging. “Not sure, I kind of like my own stink and sometimes I lose track when I get real focused on my routine of lift, eat, rest, repeat,” the big bear said. He lifted a big arm up, exposing his hairy pit, leaned in and sniffed deeply, then sighed contentedly. “Well I’ve got more shirts and tanks with me this time, ones that will actually fit you right and cover up the gut you’ve got growing,” Austin said as he reached behind his dad and jiggled the bottom of his belly. “Heh, fuck off, it comes with the territory of growing bigger! Still can’t believe it took me this long to get into putting on size and lifting. This is the best thing that’s ever happened to me,” Jon said as he shook his shake. He popped it open and tilted his head back. *glug, glurrp, slrrrrp* The shake was thick and lumpy with peanut butter, gainer shake powder, and more. Jon’s Adam’s apple bobbed up and down as he swallowed the whole shake in one go, slurping and chugging faster than Austin could believe. *glub, gurrb, sluuuuurrrrp slrrp slrrp* Jon’s gut swelled out noticeably as he drank and drank, his big tank filling up with post-workout growth fuel. “AHhhhhhh!” Jon slammed the bottle down and exhaled. *BUUUUUURRPP* He belched loudly, the burp rising up from the depths of his belly right in Austin’s face. He looked down sheepishly and grinned, rubbing his gut in a wide circle and bouncing it at the bottom. “Jesus, dad, what the fuck!” Austin said, waving a hand to dissipate the burp and stepping back. “What can I say, I’m a growing guy!” Jon said as he started warming up a pre-prepared meal kit. “I need to eat so much to grow, but thanks to your diet plan and all these food deliveries, it’s been easy to keep up with. I’m also just constantly hungry now that I’m lifting twice or three times a day instead of working,” Jon said. “Seems like I can never get enough food to feel full. It’s all thanks to you, son.” “I’m just glad you’ve taken to it so well, dad,” Austin said. “Let’s see if you can tear that old shirt open,” he said. Jon snapped to attention and dropped what he was doing and immediately grabbed the neck of his too-small tanktop and pulled on it. “RRRGGGGG!” Jon roared, and even though the material was damp with sweat and only a few weeks old, it tore right down the middle, splitting the muscled mascot logo in half. “AAaaaahhgg!” Jon took another big rip until it split open at the bottom. He spread his arms and shoulders and tore at the chest again until it peeled off of his big arms and fell to the floor in tatters. “Good, good, big bull! That was awesome,” Austin said. “You made that look easy, you big show off.” Jon straightened to his full height and spread his shoulders wide. “I’m getting real big, it feels great to grow every day and see the scale go up and up and up,” Jon said as he flexed his shoulders and arms. “I should tear up shirts like that more often! So what do you think, is all my hard work paying off?” Jon really was a changed man over the last few weeks, and not just his size. His hair was cut in a crisp high and tight, just like Austin had told him to do a week ago, a mix of dirty blond and grey where it was longer at the top. His piercing blue eyes rested under bright blond eyebrows. His cheeks were fuller and rounder from all the weight he put on. His dirty blond, salt and pepper beard had grown much longer than it was in October; it was getting long enough to brush against the chest hair of his big pecs. It was blond in the middle and darker out to the sides, with flecks of grey sprinkled in. His chest was covered with a much denser layer of hair than a few weeks ago, and even his upper arms and shoulders were dusted with patches of fur. His arms stood out to the sides a bit, pushed away from his body by his lats, and his gut was round, firm, and covered with a dusting of hair that concentrated into a line leading down to his waist. Dramatic, red stretch marks lined the sides of his belly and streaked across his upper chest, his deep armpits, and his burly round shoulders, evidence of the speed and ferocity of his growth. A huge, swollen bulge pressed out from his tight shorts, massive thighs stretching the material apart at the edges and drooping over his knees. His hairy calves bulged out round and hard, accentuated by the Otomix high tops on his big feet. Austin shook his head, astounded by Jon’s progress. He never imagined in his wildest dreams that his dad would erupt into a massive muscle bear in just 3 months of lifting, but now that they had come this far, Austin was obsessed with the idea of pushing Jon as big as he could get. “Oh yes, Jon, you’ve made me very happy. I’m so proud of you. But I know you can still get a LOT bigger,” Austin said as he gestured for his dad to start eating his lunch. “Tomorrow is Thanksgiving and I am going to make a BIG meal for you!” Jon actually looked disappointed. “But Austin, I said that I was going to cook for you, you deserve to be served on Thanksgiving and I want to show you how much you mean to me,” he started, but Jon held up a hand to interrupt him. “I’m so flattered by that, I really am, but Jon, it’s YOU who deserves a reward for all the hard work you’ve done, for following my directions so perfectly and obeying me so much,” Jon said, relishing the power dynamics; he was the alpha, and this huge brute of a man shoveling chicken and rice into his maw was all his. “I’m going to make so much food tomorrow, and I want you to eat as much as possible. In fact,” Austin said, as he walked up to his dad and wrapped an arm around his shoulders as much as he could, “I want to see you break 300lbs this weekend. I’m gonna stuff you silly, bull. Got it?” Austin said, leaning closer and talking right into Jon’s ear. Jon breathed hard and shuddered as he thought of busting past the 300lb barrier. Austin’s words echoed in his head, and it was all he could think about. “Y-yes Austin, that sounds great.” “Call me Sir,” Austin whispered, leaning in even closer. “Y-yes Sir,” Jon whispered back, his breath catching after he said it. It felt right. It felt good. “And then we’ll lift and eat and watch football and hang out the rest of the weekend,” Austin said as he rubbed the back of his dad’s thick neck. “Sound good, bull?” Jon sighed and adjusted the massive bulge that was leaking into his jock. “Yes Sir!” -------------------------------------------------------------- The dining room table had never been more crowded. Austin had done more cooking than he’d ever done in a single day to prepare a truly epic Thanksgiving for his growing stepdad. A huge bowl of buttery mashed potatoes, serving dishes filled with corn, green beans, cranberry sauce, and stuffing, several huge boats of heavy gravy, three different pies, and of course in the middle of the table, a plate full of moist slices of perfectly cooked turkey. Austin had never been motivated to cook such a perfect meal, but something about how his dad was growing, something about the joy Jon was taking in getting bigger and stronger and more muscular every time Austin saw him, filled Austin with a fervor. He wanted to fuel Jon’s growth just as badly as Jon wanted to grow for Austin. “Alright big guy, dinner is ready!” Austin called out. Jon burst into the kitchen from the garage gym, his new tank top soaked and darkened with sweat, drops of it running down his bearded face. His bloated arms were pumped from an all-day gym session; he had been lifting non-stop since that morning, pausing only to eat a little for breakfast. Besides that, he had been fasting and building up his hunger so he could eat as much as possible at dinner. His eyes widened when he saw the spread on the table and his mouth dropped open. “Austin! Whoa! This is… I’ve never had a Thanksgiving dinner like THIS!” Jon said, walking around the table and seeing all the options spread out before him. His mouth watered, he licked his lips hungrily, and the bulge in his tight gym shorts tented knowing that all of this food was going to fuel even more gains. “It’s all for you, Jon. I want to see you eat as much of this as possible tonight so you can grow!” Austin said, pulling the seat out for his big stepdad. The chair creaked as the huge musclebear sat down, a squiggly vein running from his chest, over his shoulder, and down his bicep throbbing as he reached for the bowl of mashed potatoes. “Mmmmmm, my son knows how to take care of me,” Jon said. Austin helped out by laying several thick slices of turkey on his plate before sitting down himself. For the next 30 minutes, neither man spoke more than a couple words to ask for the other to pass along more food. Instead they mostly grunted, chewed, or went “mmmph” after a particularly good bite. After his fourth helping, Austin finally threw in the towel. He stood up, feeling the roundness of his own full belly, and walked over to Jon’s side of the table. “Getting full yet, you big beast?” Austin said, noting that they had polished off about half of the food. Jon washed down a huge mouthful of food with a big swig of pinot noir; he had already drank an entire bottle himself. “Just getting started,” he rumbled as he dug in for another bite, a mix of turkey breast, mashed potatoes, gravy, stuffing, and corn. He was sweating again, this time from the huge amount of calories he was taking in, and his tight gym shorts were pressing uncomfortably against his swelling belly. “That’s what I want to hear,” Austin said as he ran a hand over his stepdad’s huge, bulbous shoulder; it was rock-hard to the touch and slick with sweat. Jon grunted and ate faster. Austin started clearing away some of the empty or half-empty trays. A moment later Austin returned from the kitchen with a brand new heaping platter of turkey meat, dark and white meats dripping with juice and steaming, and a fresh bottle of wine which he popped open before refilling Jon’s glass. Jon kept his head down, eating like a starving man, shoving food into his mouth at an alarming rate. “Still so hungry,” Jon said between bites, pausing to drink more wine and then stuffing more meat into his gob. “And all of this tastes so good, son, you did great.” “Thanks bud, you deserve it with all the hard work you’ve been putting in at the gym,” Austin said as he scooted a chair over right next to Jon. “It’s been amazing to come home and see your progress in these huge leaps and spurts. It’s kind of freaky how fast you’re growing, you know that right?” Austin said. Jon struggled to swallow a particularly big bite, then gasped for air. “Yeah, there are some days I don’t see it, but then other times I step on the scale or look in the mirror and think, ‘What the hell, I’m fuckin’ huge’, heh,” Jon rumbled as he leaned back and stretched, his damp tank top riding up the curve of his swelling belly. “I don’t know exactly how or why it’s happening, but I’ve never felt this good in my life, and all I can think about it getting bigger,” Jon said before tucking back in to his plate. “I know, big bull, I know,” Austin said. “I don’t think anyone your age has ever grown this fast, but I love it. You’re so big, and so strong, but this is just the beginning,” Austin said before slipping a hand over Jon’s huge, round thigh. Jon growled contently as he felt Austin squeeze his big quad, and the bulge in his shorts stretched tighter. “Over Christmas break we can go check it out with a doctor and make sure everything is healthy, but for now,” Austin said as he moved his hand from Jon’s bulky thigh to his round, swelling gut. “For now let’s focus on growing you as big as possible.” Jon grunted and smirked, then took another big bite. Jon finished another 2 plates piled high with food and half a bottle of wine before he started to show signs of slowing down. Gravy and drips of turkey juice dotted his dirty blond beard, his shirt was stained with food that had dropped down onto his shelf-like chest, and his distended belly button and lower arc of his gut protruded from his sweaty tank top. “I think I might be slowing down, kid,” Jon grunted as he adjusted his prodigious weight in the seat, the wooden chair creaking. “Six plates of Thanksgiving dinner is a lot of food,” he said. “Nope,” Austin said, suddenly authoritative as he looked his stepdad in the eye. “You’re not done yet. You’re gonna keep eating until I tell you to stop,” he said, and he scooted closer before slopping more mashed potatoes, a huge serving spoon full of stuffing and gravy, and three thick slabs of turkey meat on to Jon’s plate. “A-Alright,” Jon groaned. He sat up in his chair and straightened out his shoulders, which jutted far wider than his chair. “Gimme some more,” Jon said as he sniffed and grunted, his breathing heavy. His belly pressed into the table as he tried to scoot in, but found he couldn’t without pushing the table back. “Here let me help,” Austin said, and he picked up Jon’s spoon. Austin loaded up a huge spoon of potatoes, stuffing, and gravy, then brought it up to Jon’s mouth, which eagerly opened to take it. “Yeah, there you go. You wanna keep growing big, right Jon?” Austin said as he loaded up another bite. Jon nodded vigorously as he chewed and chewed, breathing out of his nose and grunting as he swallowed. “Yeah,” he breathed before opening for another bite. “Well then you gotta eat, big guy. Eat big, lift big, get big, that’s the formula, right?” Austin said, leaning in closer and pressing against Jon’s massive, sweaty arm. “That’s – *urp * -- that’s right,” Jon said. He tensed his right arm in response to Austin’s touch and flexed. Austin fed him another big bite. Jon’s bicep swelled up into a hard, massive peak as he chewed and chewed. “Yeah, that’s my big bull,” Austin purred. “I’d say today is a cheat day, but you can pretty much eat whatever you want all the time, huh dad?” Austin said. “Such a big bull, getting so huge and so fat.” Jon finished his bite then snorted like a pig. “What can I say, I’m always hungry for more! Gotta get huge no matter what,” he said before rubbing his belly in big, round circles. Austin grabbed a big piece of turkey in his fingers and raised it up over Jon’s face. Jon tilted his head back, his neck rolls bunching up, and opened wide. Austin fed it to Jon, his stepdad taking an exaggerated big bite out of it and chewing like an animal. “You’ve got a big appetite for food and an even bigger appetite for growth, huh big bull?” Jon just breathed heavily as he ate the rest of the turkey Austin held, his lips slurping against Austin’s fingers until every morsel was gone. Jon adjusted his weight as his cock thickened and pulsed until it was harder than he’d ever felt before in his life. Austin’s full attention and persuasion washed over Jon like a spell; all Jon could think about was eating, lifting, and growing. “Yeah you’re still hungry, I know you are. You’re gonna finish every bite on this table before I’m done with you, bull. You’re done when I say you’re done, got it?” Austin said, his voice dropping as their feeding session became more intense. “Yes Sir, unf, more please,” Jon grunted and then opened his mouth wide for a big slice of pie. Austin continued feeding Jon for another half an hour, gradually powering through every bite of every dish on the table, Austin rubbing Jon’s muscles and belly as he fed him. Jon’s breathing was heavy, his big chest rising and falling, and his gut was round and tight; Jon had never been fuller in his life. He was still sweating, and a potent jock musk radiated from his hairy pits as he raised his arms and leaned back after Austin fed him his last bite of Thanksgiving dinner. “Unnnngggghhhhh fuck I’m full,” Jon grunted as he stretched, his tank top rising up until it was stuck between his thick, overhanging pecs and his swollen gut. “That was some damn meal, Austin.” He reached down to adjust his shorts, which were digging into his waist, and he sighed when he wriggled them down a bit to make more room. His huge, thick cock pressed obscenely against his thigh, slowly throbbing as he felt the full hugeness of his body after the biggest meal of his life. “I’m so proud of you, big bull pup, you ate it all. Imagine how much you’re gonna grow from all this food now, mmmm,” Austin said as he rubbed Jon’s huge belly, running his hand through the blond fur and occasionally jiggling his meaty love handles or belly overhang. “We should eat big like this more often,” Jon said as he finished the second bottle of wine. He then erupted in a huge, long, deafening burp, which made both of them laugh. “Wanna go check the scale?” Austin said with a twinkle in his eye. Jon’s eyes widened and he grinned excitedly before slow pushing himself up from the table and standing to his full height. Jon led the way and Austin admired his stepdad’s wide shoulders and how he waddled when he walked, his huge thighs rubbing against each other and his big belly and lats pressing his arms out to his sides. Jon’s huge ass bounced up and down rhythmically with every step, mesmerizing Austin; he could see every inch of muscle tensing up and down, a massive jock bubble butt hugged by obscenely tight shorts. Austin’s formidable cock hardened as he followed Jon into the bathroom. Austin noticed that doorways were starting to get pretty tight for his growing stepdad. Jon stepped on the scale, peered down over his massive gut, and then grinned. “300!” Jon and Austin exclaimed together. Jon stepped down from the scale and turned to the big mirror in the master bathroom. “Fuck, I’m fat,” Jon said as he turned sidewise and cradled his bloated belly in the mirror. “Yeah, you’re so big now, Jon. You look amazing. Look at all that size, all that muscle, the power,” Austin said, showering his stepdad with praise. “Look how much you’ve GROWN in the last 3 months,” he said, standing next to him in the mirror and rubbing Jon’s big arm and shoulder. Jon turned to face the mirror again and lifted his arm to flex, his sweaty, rank pit right in Austin’s face. “Yeah, that’s a hell of a bicep, big bull,” Austin said and rubbed the massive, hard peak. It was solid; Austin squeezed harder but couldn’t dent it. Jon smirked with pride in the mirror as he watched his son try and fail to dent his hard muscle. “Yeah? You like?” Jon said, really seeing how much bigger he was than his football jock son for the first time. “All that food is gonna make these muscles grow too,” Jon said. He reached down to take his soaked tank top off, then brought his big fists together in front of his gut and flexed. He sucked in a big breath, making his pecs swell bigger, then grunted as he showed Austin how big he was getting. His traps and shoulders expanded with size as the muscles flexed, veins snaking across his shoulders and arms, and his arms tensed with hard muscle. “Look at how much bigger you are than me now, dad,” Austin said as he gestured to the mirror. “You’re so, so much bigger. What a monster, what a freak,” Austin said as he stripped out of his own shirt and flexed too. He looked like a skinny kid next to his big stepdad. Jon’s huge cock tented his shorts obscenely as they both grunted and flexed. “Yeah… bigger,” Jon grunted, feeling lightheaded from the food, the alcohol, as from how overwhelmingly horny he felt. “You look small next to my big bulk, hehe,” he slurred drunkenly. His weighty, swollen gut pressed down against the big bulge in his shorts. He turned towards Austin and raised both arms into a bicep flex. “That’s right, Jon, you make me feel so small,” Austin said as he reached up to feel, Jon’s huge arms impossible to reach around even with two hands, the overwhelming stink of Austin’s workout and dinner stuffing-fueled sweat overwhelming his senses. Jon stepped closer to Austin, forcing him to back up until he was pinned against the door. Austin took a deep breath as his hulking stepdad leaned in closer, the size disparity between them making his heart race, Jon’s huge biceps rising into perfect, thick peaks. It was all happening so fast, and Austin didn’t want to make Jon feel weird by pushing it to the next level yet. “So hey, Jon, I bet you’re feeling really full,” Austin said as he reached down to palm Jon’s big tummy. Jon shivered and laughed as he stepped back, and the tension dissipated. “Take your shorts off, that’ll relieve some tension,” Austin said. Jon stepped back and slid the gym shorts down revealing a tight pair of sweat-soaked blue briefs. The outline of his cock head was clearly visible, a sizable bulge stretching the fabric out. “Why don’t we go out to the living room and watch the game? We can lay down and digest that big feast,” Austin continued as he put his shirt back on and stepped out of the bathroom. Jon followed obediently, but kept his shirt off. “Yeah, the game! Good idea. Definitely need to let all this settle,” Jon said as he smacked his gut and gave it a rub. Austin sat down on the loveseat, and Jon started moving towards the recliner. “Why don’t you come over here and sit with me, Jon?” Austin said. “Sure thing, bud,” Jon said, immediately obeying Austin as usual. The big bear rumbled over and wedged in next to Austin, the two of them clearly too big to share the little loveseat that had fit them just fine a few weeks ago. Their shoulders pushed against each other, and Jon’s wide ass and big legs brushed against Austin’s. Austin tried to lean back and make some more space for himself, but Jon’s wide frame wouldn’t budge. Austin turned the football on, as was tradition on Thanksgiving, and wriggled around to try to get comfortable against his mountain of a stepdad. Jon’s arm pressed harder into Austin as he relaxed, the damp mass of his triceps getting Austin’s shirt wet with dad sweat. “Jon, why don’t you try this,” Austin said as he lifted his dad’s right arm up and placed it around Austin’s broad shoulders. That freed up some room between them, and Jon leaned closer to stay pressed against his stepson. “Mmmm yeah that’s better,” Jon purred as he relaxed, letting out his full tummy and sighing contentedly. His arm smeared sweat all over Austin’s neck and traps, and his hairy, sweaty, stinky armpit rubbed right against Austin’s left shoulder. A heady funk filled Austin’s nose, inescapable at this range, and he breathed it in like a drug. “Jeez, dad, you smell like the locker room on game day,” Austin laughed, turning his head a bit to breathe in his dad’s musk. “Oh jeez, sorry, I didn’t even think about it,” Jon said, embarrassed, and started to pull away. “No no, it’s… I actually kind of like it,” Austin said and he put his left hand on Jon’s right thigh, rubbing it firmly all the way up to the hem of his briefs. “Leave your arm right where it was, I want to smell it some more,” Austin said, and Jon put his arm right back, leaning even harder against his smaller, leaner son. “Mmm, ok,” Jon said. “Guess it reminds you of the locker room, huh?” he said. “I bet you’re kinda sad about your last season being over, huh?” Jon said. “Yeah, for sure,” Austin said. “It’s sort of the end of an era, something I’ve been doing since I was a kid. But also, I’ve always just loved the gym more, lifting and getting bigger. You know?” Austin said and leaned his head back against Jon’s meaty bicep. “So now I can just focus on that. Plus, I won’t miss practice and all the injury risks,” Austin finished. “Yeah I totally get that,” Jon said. He adjusted his weight, the loveseat creaking underneath him, and Austin got a fresh wave of BO stink in his face. Austin sniffed the air deeply then sighed and grunted. “Mmph, I never want you to wash these pits again, bull, you got that?” Austin said authoritatively, turning to look Jon in the eye. “Mmmm yes Sir,” Jon said as he lifted his right arm and leaned in, getting his hairy, musky pit right in Austin’s face, his biceps and shoulder muscles bulging. Austin turned and rubbed his nose in it, getting Jon’s potent sweat all over his nose and upper lip. Austin pulled away and relaxed again, sniffing his upper lip and grunting. “Unf, good, mmm,” he said. They both laid back and relaxed, leaning against each other more heavily. “I like this,” Jon purred and he squeezed Austin with his extended right hand, pulling him in closer and pressing him against his big bulk. “Feels good next to you.” Jon’s cock stiffened, tenting obscenely and obviously, unable to hide it, but they both ignored it for now. “Yeah?” Austin said, trying to contain his growing hard-on and taking a deep breath. It was hard to calm down and stay in control with Jon’s pit stink making his head spin. “I bet you’re kind of lonely here by yourself, huh?” Austin said. He tried to focus on the game, but couldn’t help but rub Jon’s big, hard right thigh. “Yeah that’s kind of the one thing I’m missing,” Jon said. “The gym has given me a great new focus, but I want to share it with, well, with you more,” Jon said. Austin switched to rubbing his stepdad’s gut in big, slow, round circles, feeling the distended mass of his belly full of food. “Well we can cuddle like this. Nothing wrong with gym buds relaxing a little together,” Austin said. He lifted his right arm and flexed, and his stepdad squeezed and felt the round, hard bicep and shoulders appreciatively. “Mmm nothing wrong at all,” Jon said. “Your arm feels great too, nice and muscular. You’re a lot leaner and harder than me,” Jon breathed. He rotated a bit, bringing his left arm close enough to reach over and feel Austin’s solid chest. He slipped his hands under Austin’s shirt to feel his cobbled abs. “Yeah, wow, you’re jacked, son,” Austin said. “Thanks, Jon. Was doing it for the team but now that my football career is done, I’m doing it for you. We can get big and jacked together,” Austin said, flexing his leaner, hard chest muscles for Jon. “Fuck yeah,” Jon breathed. “I like the sound of that.” They sat quietly for a bit, idly rubbing each other slowly and watching football, Jon’s full tummy grumbling occasionally and his sweaty pits filling the room with jock stink. They did a player profile on some huge linebacker during a timeout, showing his lifting routine, the big NFL player sweating and flexing as he showed off his size. “You know Jon, you’re bigger than most of these guys already, especially now that you’ve crossed the 300 mark” Austin said. “Well except the linemen, but you’re catching up!” he said and he gave his stepdad’s belly a jiggle. Jon grunted and wriggled against the smaller jock, then pressed his weight against him, crushing him in to the loveseat armrest. “Yup and it took me just 3 months to get there, thanks to my coach,” Jon said. “Belly and all!” “Well you’re gonna outgrow those guys real soon if you keep doing what I say,” Austin said. “And you’re definitely gonna keep listening to your coach, right?” he continued, turning to look Jon in the eye then reaching up to grab Jon’s beard and tug it gently. “That’s right,” Jon breathed. “Or maybe even bigger than that strongman we were watching last time I was here for fall break, remember? He was 450lbs. I bet you can pass that if you keep this up, dad,” Austin said, rubbing Jon harder. “Of course, little Sir,” Jon said as he lifted his chin so Austin could rub his thick beard better. “Little Sir, huh? I kinda like the sound of that,” Austin said with a grin. “You know, it sounds kinda weird, but I love following your directions and having you tell me what to do,” Jon said tentatively. “I kind of got that feeling, bull,” Austin said as he rubbed Jon’s beard. “You need a strong presence in your life to give you a direction, don’t you?” he purred. He felt something unlock inside of Jon, like he was letting his guard down even more, and Jon’s heavy bulk leaned against Austin even harder. “Y-yeah,” Jon sighed, feeling relieved he could give voice to this powerful feeling. “I do, I really do. I need it,” Jon said, almost in a whisper, as he gave in to his submissive feelings. His bulge twitched and a wet spot on his briefs grew. “That’s good, my big musclebear dad,” Austin said. “Now, you just rest yourself against me and relax and let me take care of everything,” Austin said, and Jon did just that, wrapping his arm around Austin even tighter and leaning his massive shoulder and chest against the smaller college jock. “Good pup,” Austin said. “Pup?” Jon asked, with an anxious, eager tone in his voice. “That’s right. That means I’ll always look after you, especially when we grow and eat and cuddle together. How’s that sound, pup?” Jon sighed contentedly. “Sounds great, Sir.” Jon was soon snoring, the big heavy meal causing him to doze off against Austin’s chest, and Austin smiled down at his big submissive dad contentedly.

Previous chapters: Chapter 1 Jon makes great progress with his new lifting and diet routine, which impresses Austin. The guys start growing closer together. Chapter 2 — Fall Break Austin pulled into the driveway of his dad’s house. It was fall break, really just a glorified long weekend but good enough for Austin to make the journey back home from college. Austin closed the door of his brand-new black Ford F-150, his one big splurge after getting his inheritance money. Austin and Jon texted every day and he had called his stepdad a couple times since school had started, mostly to keep Jon company and to check in on his gym progress. Jon was devoted, Austin gave him that… every day he’d text Austin which exercises he had done, a summary of what he had been eating, how long he lifted, everything in great detail. At first they were just in text messages, but soon they were links to a shared Google Sheets page, everything organized in rows and cells. The one thing Austin couldn’t see is what weights his stepdad had been using for all these different lifts, as his dad had set a filter on that so only he could see. The other thing that Austin didn’t see was any pictures. Jon wanted to surprise his stepson on the progress he’d been making. Austin had made progress on his own; he’d put on another 5lbs of muscle and was in top in-season shape. At 6’0” and 235lbs, he was the biggest and best quarterback of his D-3 conference at the small private school he went to. He also had a 3.8 GPA and was acing all of his classes. Austin approached the front door, carrying a weighty duffel bag full of dirty laundry, and found it unlocked. Inside, the house had changed in the last 6 weeks. It was less organized, less neat, and smelled differently; gone was the clean scented candle smell his mom cultivated, replaced with something else. It smelled masculine, fresh but tangy and sharp, a mix of his stepdad’s beard oil and his team’s football locker room. “Jon?” Austin called out, but didn’t hear any response other than music coming from the basement. Austin dropped his bag and made his way downstairs, following the narrow stairs and low ceiling into the basement. As he made his way down, he spotted someone doing pushups. Austin arched his eyebrow, a little confused, because it didn’t really look like his stepdad; this guy was way too big to be Jon. The stranger cranked out pushups tirelessly and with perfect form, quickly going up and down, up and down, squeezing each rep. “Hello?” Austin said. The stranger stopped mid-rep and then twisted around to see. Jon got up from the mat and stood to greet his stepson. “Austin! There you are! Welcome home, son!” he said as he wiped the dripping sweat from his forehead onto his shirt, revealing his furry and hard-looking tummy. He stepped forward and embraced Austin in a wet hug. “J-Jon? Wow, I mean, it’s great to see you, I didn’t even recognize you!” Austin sputtered as he embraced his stepdad. He could feel how much more solid, how much wider, how much bigger Jon was all over. “You… you look incredible, Jon!” Jon stepped back and puffed out his chest, proud and eager to show off his gains to Austin. “You think so? I know I’ve been making some progress but not sure how much you were expecting,” Jon said. His shirt was way too small, soaked and dark under his pits, down the middle of his chest, and across his bulging tummy. The shirt had a cartoon version of his stepson’s college football mascot, the Saint Brian Tigers; the tiger was huge and muscular, bowling past the mascot characters from rival schools. His solid-looking arms strained the tight sleeves, and his chest and traps made the front of the shirt ride up and strain in the middle. A sliver of hairy tummy stood out at the bottom, a slight overhang over his mesh shorts. His shorts, too, looked small and struggled to contain his muscular thighs. His quads bulged out to the sides and down, with ample muscle hanging over his knees and bulging calves. Jon had grown a short beard, the middle of it blonder and longer than the cheeks and sides, with sprinkles of grey spreading throughout; his hair was a mess of short dirty blond curls. “Jon, you… holy shit, I mean, I’ve never seen progress like this before!” Austin exclaimed, flabbergasted. “I knew you had been working hard and following my plan, but this is… wow!” Austin said, and stepped closer. Jon flexed his right bicep and smiled, showing off for his stepson as the muscle pushed back the tight sleeve of his t-shirt. “You like?” Jon asked, an uncontrollable grin spreading across his bearded face. “Your plan has really been great. You did such a good job coming up with it. They must really be teaching you good stuff at college!” A wave of sharp musk radiated from his sweat-soaked shirt and armpits as he raised his arm, the same smell that Austin had smelled upstairs. “Feels solid, dude, way to go,” Austin said as he rubbed the hard peak. It wasn’t the biggest bicep Austin had ever seen, but it was solid and bulging with new muscle. “Just how big are you now, Jon?” Austin asked, a little overwhelmed by his suddenly jacked dad. “Weighed myself this morning, I’m 225 lbs now… gained 50 pounds since you last saw me! Is that good?” Jon asked, stepping back and turning sideways to show his thickness. “I’ve been following your instructions exactly, Austin, and I gotta say, I don’t know why I didn’t start lifting sooner. I’m getting kind of obsessed with it!” Jon said as he flexed his chest, breathing in sharply through his nose and grunting out through his mouth, bits of sweat dripping off his nose and eyebrows. Austin was speechless. 50lbs in 6 weeks? How was this even possible? He laughed at the absurdity of it. “Uh yeah I can see that! These gains are incredible, Jon! You’re almost as heavy as me now, though I’ll still always be taller,” Austin said as he stood closer, to prove his point. “Heh, I guess so. Let’s go upstairs and eat, I’m starving!” Jon said and the two jocks went to the kitchen. Jon’s kitchen had become a mess of Tupperware, half-cleaned dishes, shaker bottles, and jugs of protein powder and supplements. “Jon, you gotta clean this place up. You can’t make as efficient of gains if you’re not organized,” Austin said. Jon looked around the kitchen. “Yeah, you’re right son,” he said. Austin paused for a moment, then sat at the dining room table and looked over at Jon. He wondered what else Jon would do for him. “And make me a protein shake too. You remember the recipe I sent you a couple weeks ago?” Austin said as his stepdad grabbed two clean shaker bottles. “Of course, son, coming right up,” he said. He loaded up the first shaker bottle with two scoops of chocolate protein powder, a banana, oats, peanut butter, olive oil, and water. The second one he did the same but doubled all the solids. “I’ve been doubling the recipe lately because just one wasn’t filling me up. I hope that’s ok!” Jon said. There was so much in the bottle there was hardly room for it to shake. “Yeah Jon, of course. You’re really serious about these gains, aren’t you?” Austin said as his stepdad walked over to him. He really did look amazing, like a fit ex-jock who lifted every day. It was already such a dramatic change from when he last saw him, and Austin got the feeling this was just the beginning. “I really like drinking these shakes, especially since it was you who gave the recipe to me,” Jon said as he stood next to his stepson. “They’re definitely helping with the gains!” He raised the bottle to his mouth, tipped his head back, and chugged, the thick sludge disappearing quickly. “*glug, glug, sluurrrrp, slllrp, glub glug, slluuuuurp slllrp*” Jon rubbed his stomach as he chugged, the shake filling him up as it disappeared. His tummy bulged out round and taut, making his shirt ride up a little, and he took a big breath when he was done. “Grrruff, mmph, *sniff*, that hit the spot! Now I’m ready to make dinner for us,” Jon said. Austin just watched all of this in wonderment. No wonder his stepdad had grown so much since he last saw him. “Jon, you doubled the shake recipe and you’re still hungry?” Austin asked as Jon started cleaning up the kitchen, just like Austin had asked. “Since you told me to start lifting, it seems like I’m always hungry! I guess maybe I’m eating a little too much since I have a little bit of a tummy too, I’m not cut like you are,” Jon said. “Maybe it’s also the beer I’ve been drinking.” “You should keep drinking that, though,” Austin said, the words coming out before he could stop them. Wait, did he want Jon to keep getting bigger and have a bit of a tummy? Yeah, he realized, he definitely did. It would make Jon look even better. Austin adjusted his crotch as he thought about his handsome, older stepdad growing into a proper daddy muscle bear, pushing past 250lbs or maybe even bigger. “The extra calories from the beer, uh, help round out your gains and helps dull joint pain. I read a study about it in class,” Austin lied. “Great!” said Jon as he reached into the fridge and cracked open a cold one. “Make spaghetti, a double batch with 3lbs of beef. And make garlic bread too. I’m gonna take a shower,” Austin said. “That’s a great idea!” Jon replied enthusiastically and started cooking. -- The next day, the guys got up and had a big breakfast. Austin again asked Jon to cook, and his stepdad was eager to do so. They loaded up on carbs and protein and headed to the gym together, both of them packing into Austin’s F150. At the gym, Austin was unforgiving, putting Jon through his paces with an intense push day. They started with dumbbell bench press, Austin urging Jon to try 90lb dumbbells that he had never had the courage to try himself. They did decline and incline, Austin making Jon go until failure on every set, pushing him to new PRs. Jon grunted and groaned, his focus intense, his form always perfect, eager to prove himself to his bigger, stronger stepson. Sweat dripped off of Jon’s nose as they went over to do cable flies, Austin making sure he squeezed and paused at the top of each rep. Austin was blown away by how strong his stepdad had become in such a short time; it wouldn’t be long until the 42-year-old caught up to his virile college football athlete stepson if he kept this up. By the time they were done with their workout, their tank tops were a different shade than when they arrived, soaked in sweat and clinging to their pumped-up bodies. They eagerly guzzled protein shakes in the parking lot before riding home, talking about their favorite lifts. They drove home, both of them buzzing with a gym high. They got out of the truck, and Austin walked over to Jon. “Jon, there’s one more thing I want you to do today, and that’s mow the lawn. And I want you to do it shirtless so you can show off all the awesome progress you’ve made to the neighborhood!” Austin said. Jon looked down at his shirt, the Tiger mascot looking darker because the shirt was soaked with sweat. It was an unseasonably warm afternoon, even though it was mid-October. “I don’t know, Austin, I usually wear a shirt when I’m lifting and I don’t think I’m really fit enough to—“ Jon started. “Stop. No way, Jon, look at you,” Austin started. He walked up to his stepdad, reached out and patted his arms and shoulders. “I mean, damn man, you’ve beefed up so much since I’ve been gone. Look at your biceps, I mean really flex and look at them,” Austin said, trying to pump Jon up. Jon flexed his arm timidly at first, but then with more gusto when he looked down and saw them. He lifted his arms up and flexed harder, his biceps bulging into hard, impressive peaks. Austin squeezed and felt Jon’s big arms. They were already almost as big around as Austin’s. “Yeah, jeez look at those big hard guns. You think most guys in their 40s are built like this?” Jon couldn’t help but grin and he scratched the back of his head, making his round bicep peak bulge out more. “Heh, yeah I guess you’re right, son,” Jon said sheepishly. “If you think I should, I guess I will mow shirtless. Why not!” he said. With that, he peeled off his shirt and headed for the garage. He soon emerged with the lawn mower. He was already soaked with sweat from the gym, and after just a couple minutes in the hot sun, he was drenched again, sweat dripping from his arms and chest, his shorts turning darker as they soaked through, revealing a prominent bulge bouncing back and forth as he walked. Bulging dad muscle on display for the entire neighborhood to see, furry and sweaty and hot. Austin sat on the front step and watched his stepdad, his pumped shoulders and biceps gleaming with a sheen of sweat in the afternoon sun. Jon looked over and smiled, seeking Austin’s approval. In that moment, Austin knew he was in charge. The power dynamic of the house had shifted, officially. He was the alpha dog. And Jon would do whatever Austin wished. -- Jon finished cleaning up after another enormous dinner and another post-meal protein shake. Austin had Jon drinking 5 shakes a day on top of 5 meals so his growing stepdad had a regular intake of calories and protein. His shirtless torso bulged with muscle and a round, full tummy as he walked into the living room and sat down next to Austin, who was watching football. They had to share the loveseat, because the recliner was piled high with the most recent shipment of Jon’s supplements and protein powder. They both had wide shoulders and took up most of the space, only a few inches between them. “Your season has been going great, son, I’ve watched every game,” Jon said. “You’ve been great reading the defense and shedding defenders. Your increased strength is paying off!” he said, beaming with pride. “I was so impressed with you at the gym today too, bud, I’ve never seen a guy your age be that strong,” Jon said, patting his stepson on the back and rubbing his neck. “Beast!” Austin sat up straighter in his seat and spread his shoulders wide. “Heh, you’re telling me, I’ve never seen anybody make the gains you’ve made over such a short time, Jon,” he said, appreciating his dad rubbing his neck and shoulders. Jon’s raised arm exposed his pits, and Austin could smell the fresh, ripe smell of musk, the kind you get after a hard, sweaty workout. “You’re gonna pass me if you keep this up, old man. But yeah, I had to get a new set of pads, the ones I had freshmen through junior year were too small, too tight,” Austin said and shifted his arms around, flexing his shoulders and traps. The football game went to halftime and the guys switched over to watching World’s Strongest Man on ESPN. Austin got an idea as he saw one of the big strongmen getting massaged between events. “Say Jon, why don’t you rub my shoulders? They’re feeling tight after the gym and it would feel great if you rubbed them. Plus, you owe me as your trainer!” Austin said as he stood up, looking down at Jon. Jon looked up at Austin and adjusted the bulge in his gym shorts, his hard thighs shifting wider to make room for his stepson. “Sure thing, bud, have a seat and let me loosen you up,” Jon said. Austin took his shirt off, revealing his naked torso to Jon. Austin’s wide shoulders framed his broad, meaty chest. Abs studded his stomach, which were covered in a light dusting of brown hair. “Wow, son, you really are jacked, look at you!” Jon said. Austin smirked at Jon and flexed his bicep, the peak bulging up bigger than Jon’s had when they were outside. Austin got a whiff of his own musk; Jon wasn’t the only one stinking up the living room after his workout. Austin sat down and leaned back against Jon’s warm thighs. Jon started rubbing Austin’s hard traps, kneading his fingers into the dense muscles. Austin could feel the rough gym callouses his stepdad had developed over the last couple months scrape against his neck and upper back as he dug in. “Oooooh yeah wow Jon, that feels great,” Austin groaned as his stepdad rubbed harder. “You’re pretty good at this, you know?” “Your mom had me train to be a massage therapist a couple years ago because she said I wasn’t any good at it. Guess I picked up a thing or two. The things we do for love…” Jon said as he leaned down and pressed his forearm and elbow into Austin’s traps and down his shoulder blades. “Uuunnnnnggggg damn that’s it,” Austin moaned as Jon loosened his hard muscles. Austin could feel and smell Jon’s breathing on his neck as he rubbed and rubbed; his breath smelled like protein shake and his beard had a whiff of cedar beard oil. The combination of all the different smells in the room made Austin’s head spin and his cock pulse. “Feels amazing,” he cooed. “Mmm glad you like it, son,” Jon said, his voice deep and relaxing. Austin could feel Jon’s bulge shift and throb as he leaned harder into his tight muscles. This was clearly turning Jon on, Austin realized. Austin felt a flitter of excitement for the forbidden but undeniable attraction to his stepdad. Seemed it was mutual, to his surprise. He had assumed Jon was straight, but apparently not! Austin took a deep breath and sat up a little bit, creating a little distance between them. He had to take this slower. Austin looked up and saw last year’s strongman champion on the screen, a hulking monster at 6’8” and over 450lbs. He had a flash of Jon somehow getting that big, transforming him into a massive muscle monster with bulging arms and shoulders like the big strongman on TV. Austin knew something extraordinary was happening with his stepdad; no one grew that fast, especially not in their 40s, but somehow Jon was doing it. How far could Austin push it? Jon seemed to love it, totally addicted to the gym, the growth, the lifestyle of being a lifter. Austin knew he had to try. Jon continued rubbing Austin’s back until the football game came back on. “Alright Jon, now it’s your turn. You deserve it after such a long day,” Austin said as he stood up to switch spots. Jon stood up too, and suddenly they were face-to-face, brushing past each other, both of them shirtless. They both grinned awkwardly and then shifted past each other to get in place, Austin on the chair and Jon between his legs, pressing back against the quarterback’s firm thighs. Jon’s traps and shoulders were firm and plump, ruddy from his workout. Austin could feel how much harder and bigger his stepdad was than when he had left him just 6 weeks ago. He could hardly believe it… the hard muscle shifting around in his grip felt nothing like the soft, flat shoulders that were there not long ago. “Ohhhhh, mmmm son this is great, keep rubbing,” Jon groaned. The sounds of football washed over them and Austin rubbed Jon’s shoulders, both of them relaxing but feeling an undeniable tension. When the game was over, they both headed up to shower and said goodnight to each other. Austin could hear Jon grunting and then yelling in the shower… was that his stepdad jerking off? He had plenty of reason to, after the tension he felt between them and the heavy lifting they had done. -- Austin threw his fresh laundry and other stuff into the bed of his truck. He was wearing a black tank top with the school logo on it and short white gym shorts that did little to conceal his prominent bulge. “Jon, it’s been awesome staying here the last few days. I’m so proud of the gym progress you’re making. You seem so much happier than last time I had to leave,” Austin said. Jon was wearing a tight grey polo and khakis, as he had work later that morning. “I wish you didn’t have to leave, but I can’t wait to get more workout and diet plans from you, son. I’ll be bigger than ever next time you see me!” Jon said with a spark in his eye. He lifted up his right arm and flexed, the peak pushing back the tight sleeve of his polo shirt and exposing his big bicep. “You better be, or else I’ll be disappointed!” Austin said and lightly squeezed Jon’s bicep. “Jon, there’s something else I want to talk about.” “What is it, son?” Jon said. “I’m so happy with your gym progress, Jon. It’s given you a new direction and given me a project I feel so passionate about. And you know, we have so much money that mom left us. I want to build on this,” Austin said, stepping closer to his stepdad. He put his hands on Jon’s chest and felt the muscles of his pecs through through the tight polo. “I want to see you push your limits and really grow. You understand?” Austin said and looked Jon right in the eyes. Jon looked up at his stepson. He felt a quiver of excitement in his chest, just like Austin had felt the night before. “Y-yes, son, I do understand. More than you know,” he said. “Good. I want you to go into work today and quit your job. You’re going to start devoting all of your time to lifting, eating right, and maintaining the house, got it?” Austin said. “You are my first priority, and I can’t get the most of you if you’re distracted by work.” “Are… are you sure? I mean, I’ll have so much time, and what about money, and,” Jon sputtered, his old insecure self coming out for a moment, but Austin wrapped his arm around his shoulder. “Don’t worry about any of that… dad,” Austin said. It was the first time he had ever called Jon his dad, but after this weekend, it felt right. “I’ve got it all under control.” Jon’s mouth dropped open a little. “Did you just call me… oh son, I’ve been hoping for that for a long time,” Jon said, clearly moved. They hugged and patted each other on the back. “Well dad, I’ve got something else for you too,” Austin said as he reached into his backpack on the ground. “These are tank-tops from the team store at college. I’ve been saving them for the end of the weekend, and you’ve earned them,” Austin said and he tossed them to his dad. Jon caught them; three tank tops, all with different motifs of the school’s football mascot logo, one straightforward and clean, one the old-school logo from the 70s, and the other a more cartoonish one with the tiger flexing his huge muscles over a vanquished rival, snarling and wearing football pads and cleats. “You are to wear these and only these during your workouts between now and when I get back for Thanksgiving break, got it? Take off your shirt and try one of these on, now,” Austin said in a firm tone. Jon did so right away, but struggled a bit to get his polo off. He slipped on the tank top and looked awkward. He wasn’t used to wearing them. “This’ll take some getting used to… and, Austin, these… these don’t really fit! I mean, it’s an XXL,” Jon said. He was right, the tank top was a bit too big for him and sagged off his shoulders and drooped below his waist like a pajama shirt. “You’ll grow into it, dad. I challenge you to make it be too small come Thanksgiving,” Austin said with a smirk. Jon grinned. “You’re on!” Austin climbed up into his huge truck and started it up, the loud diesel engine rumbling. “Oh dad!” he called down to Jon. “One more thing. Expect some delivery and installation guys in the next few days,” “What for?” Jon asked, looking a bit silly in a tank top and khakis. “I’m turning the garage into a professional-grade gym. You’re gonna have everything you need right here at home to get fucking huge. Sound good?” Austin said as he put his sunglasses on. Jon raised his chin up to look at Austin. “Sounds amazing,” he said and an uncontrollable smile spread across his face. He couldn’t wait for Thanksgiving to show the progress he was going to make for his son.

At long last, I'm starting to post my new story! I've been working on this on-and-off since before the pandemic. Motivation over the last couple years has been sporadic and life has been busy, but I'm really happy with the final product. I want to thank Jon (boston_muscle on Insta, collegeboy on here) for providing the initial inspiration for the story; though the story ended up going in different directions than we originally chatted about, I hope you will still like it, pup. I also want to thank my friend Claude (Huskythick on CF) for being my sounding board and proof reader. His contributions made the story significantly better! This first chapter is mostly set-up, but trust me, things start growing and heating up very soon. Chapter 1: Summer Break Austin stared down at the file that the family lawyer had given him a moment ago. He was in the lawyer’s office, and suddenly he felt very alone. It was his mother’s last will and testament, for him and him alone to see. He opened the leather-bound folder and started reading what his mom had left. It was a somewhat unusual move that his mother, a powerful, wealthy lawyer known for winning nearly every case she ever tried, had left everything to him instead of Austin’s stepfather Jon. Her and Austin had always shared a close bond, being so similar in personality and looks, but usually the husband received the inheritance. Austin was also only 21, about to enter his final year of college, and though he was mature and intelligent beyond his years, it was still a little daunting. Austin paged through the documents of his mother’s will, his eyes popping a bit seeing just how much wealth his mother had accrued in her 52 years. Investments, property, trust funds, millions of dollars of liquid assets and more. He would be set for life and free to live comfortably. “Thanks mom,” Austin said to himself quietly, his voice deep but tender. Arriving at the final page, he shifted his 6’0”, 230lb athletic frame as he sat up in the chair. It was a letter, hand-written from his mother. Dear Austin, My dear. I’m so sorry to leave you like this. You have been my greatest achievement, and I’m so proud of everything you have done and everything I know you will accomplish in the future. I’m just sad I won’t be there to watch you thrive as an adult. You will always be my son, and I will love you forever. You know that I’m a strong-willed person, and you are your mother’s son. I admire that confidence, leadership, and attitude that you got from me; use that, and you will achieve whatever you want in life. We have even more in common than you know, which is why I am leaving everything to you. Austin raised an eyebrow and couldn’t help but laugh at that paragraph – especially at the line about his “attitude”. She knew him too well, and he knew he got that from her. I’m sure you will know best how to use everything I have left behind for you and Jon. Oh, Jon. Out of everything I leave behind, I am most concerned about him. Jon is the most supportive, caring man I’ve ever known, and the five years we were together were some of the happiest in my life. He was the perfect complement to my headstrong nature, happy to follow my lead. I couldn’t have asked for a better match. But Jon is a man who needs direction, who needs a strong influence and leader in his life. Without me, I am afraid he will drift into depression, apathy, and loneliness. Austin, I am asking you to help take care of Jon after I am gone. I know this sounds strange, because he is twice your age, but give him something to focus on, a new direction, when I’m gone. You are so talented and driven, I know you can help him find something to inspire him. Austin sat back and took a deep breath. His stepfather was a nice guy, and the few years they had known each other were positive. But he still felt like he didn’t know him very well, even after five years. In high school, he was busy with football, wrestling, and being the valedictorian of his graduating class, and during college he was away from home for most of the year at a school hundreds of miles away. Austin knew Jon was everything his mother had said – kind, supportive, eager-to-please, generous with his time and efforts – but he didn’t know the man well enough to lead him like his mother had. Finally, I leave to you my greatest gift, and my greatest secret. It’s something I was going to share with you after you graduated from college, but my time is up. Austin, our family comes from a long line of extraordinary people – leaders, generals, royalty – and you are the latest in that line. We didn’t achieve these things by accident; when you finish reading this letter, you will be blessed with the power that I have, that my father had, that my ancestors had. The power of influence, the power of leading and shaping people as you see fit. You must use this gift to improve the lives of people around you, to help others achieve greatness and help you achieve greatness yourself. It is a gift not to be used lightly. It is a gift you must keep secret, even from your stepfather. Love, always Mom Austin sat up, looked around the room to make sure that no one else was around. What the hell? His mother always had a way with people, could convince anyone of just about anything (which had made her an excellent lawyer), but this was just silly. Had the chemo drugs gone to her head when she wrote this? He looked back down at the letter, and the final line was in a script he had never seen before, but instinctively he knew how to read it. He did so, intoning the words to himself as he did, and the words flashed on the page and then disappeared. Austin felt a burning tingle in his eyes, and he blinked hard, feeling something shift inside him. And then it was gone. He looked back down at the letter, and it was just a blank page. -- In the weeks after Austin read the will, life was a hectic blur for the young quarterback. Suddenly he was thrust into a world of transferring account information, meeting with financial estate planners and investment brokers, bankers and funeral home directors. It was hardly fair for someone just 21 years old, but Austin had little choice, as his stepfather Jon was in no shape to help out. Jon had been listless in his mid-30s when he had met her. He had always been attractive: curly, dirty blonde hair and beard that was lighter near his goatee, an effortlessly athletic build that hinted at untapped potential, and piercing blue eyes. He was a very average 5’10” and 175lbs, lean and trim, which is just what Jennifer wanted. She didn’t allow him to get any bigger than that. Jon had dropped everything to be with her, a powerful, self-made woman who gave meaning and direction to his life, who he was happy to support in every way: cooking, cleaning, running her errands, shopping for her, arranging travel and finances, even sharing her bed with other partners. He had become quite the accomplished chef in his years serving Jennifer. Austin saw that once Jon put his mind to something, he went at it with gusto, but without direction, he seemed to wilt like a plant without water. And now she was gone. No wonder he had spent the last two weeks of August sitting on the couch in their palatial suburban home mindlessly watching TV and eating takeout. He had become listless and increasingly out of shape; he had lost the fit, lean look that Jennifer had preferred. Work didn’t offer much of a spark for Jon’s life either, as he worked a mindless office job at an insurance company. He went through the motions, just like he was going through the motions without the person who had given meaning and direction to his life. Austin saw all of this as he worked through the aftermath of his mother’s death. At first he didn’t know what to do about Jon, thinking that his step-father who he didn’t know that well wasn’t his responsibility. But then one day, as he saw Jon slouched over on the couch and eating cold leftovers, he remembered what his mother had said in her letter: “Take care of Jon after I am gone… give him something to focus on, a new direction”. Austin sat down on the couch next to his stepdad. “I can tell you’re having a rough time processing all this. Do you want to talk?” Jon turned to Austin and tears welled up in his eyes. He looked like had been waiting for Austin to ask him this exact question for days. “I… I just don’t know what to do now. I feel… so lost,” Jon said before taking a deep breath to try to collect himself. “Your mom was everything to me. And not just like emotionally, I mean she was the direction and drive for everything in my life. Without her, I just… I don’t know who I am or what I should do. I’m sort of helpless on my own,” he said with a mirthless chuckle. Even though he was just 21 to his stepdad’s 42 years old, Austin realized he was so much more mature, in a lot of ways: he had always been self-motivated, was taller, bigger, fitter, and stronger, and knew how to lead people and take command. Austin reached out to pat Jon on his shoulder and noticed how flat and soft it was. Maybe that could be a starting point… Austin was an exercise science major and he knew that, in addition to its physical benefits, exercise helps improve one’s mental well-being too. “Well Jon, maybe I can help with that now. I could set you up with a working and training regimen to give you something to focus on. It would be good practice for me too, like you’d be my first personal training client! What do you think?” A light flickered in Jon’s eyes, the kind Austin hadn’t seen since his mother had passed. “Yeah… yeah that sounds like a great idea! What would you want me to do?” Austin felt a tingling in his neck, like the feeling he got when he finished his mom’s letter. Could it be… “Jon, have you ever thought about adding some bulk to your frame?” Austin asked, looking directly at Jon. “It’s great for your metabolism and you have the perfect, natural build for adding more muscle. I think you’d take to it really well,” Austin said. Jon’s face lit up like a revelation had come over him. “Yeah… yes! That’s exactly what I’ve always wanted. Your mom always preferred to keep me lean and hard, but I admit, I’ve always wondered what it would be like to be bigger. My dad was a weightlifter and my mom’s side of the family is full of huge guys, so I have the genetic background for it,” Jon said excitedly. He set his leftovers aside and shifted his weight around to Jon. “Tell me everything you want me to do!” Austin smiled. -- The first two weeks of working out together went really well. Jon took to lifting like a natural, and Austin loved bossing his stepdad around the gym and pushing him to work harder. Jon finished his first few workouts extremely sore and tired, but got over the back-to-the-gym hump quickly with Austin’s adept coaching. They would work out for hours – stretching, lifting, active recovery, Austin teaching Jon as many different kinds of lifts as he could from his college classes. Jon listened and followed every instruction like a perfect pupil and was always eager to please and eager to do what he was told. If Austin said jump, he’d jump until he was told to stop; if Austin said to push, Jon pushed as hard as he could, always putting in maximum effort. At home, it was the same. Austin threw out all the crap food that Jon had around the house and revamped Jon’s entire diet. Austin worked hard to create a new meal plan for his stepdad, a binder full of daily instructions for exactly what to eat, recipes on suggested meals, snacks, and pre and post-workout shakes, everything that would be needed to help Jon pack on size. And money was no object; he set Jon up with food catering and delivery services to get food, protein powder, and pre-prepped meals flowing in constantly. Meanwhile, Austin heaped praise on his new client, telling him how proud of was of Jon’s hard work, how much he wanted to help him achieve his goals, praising every little improvement and encouraging his stepdad to keep getting bigger and fitter. And by the time Austin was set to go back to college, Jon had everything he needed – motivation, workouts, food, and a goal – to succeed. Throughout those two weeks, a new dynamic had built up between the two of them. Whereas once it was a little awkward and Austin looked up to his stepdad as an adult in charge, now it was clear that Austin was the one in charge. Jon had taken to following Austin’s instructions not just in lifting but in everything else around the house too. “I’ll be back in 6 weeks for fall break, Jon,” Austin said as he finished loading up his truck to drive back to college. Jon was wearing a sweat-soaked t-shirt and gym shorts. He was noticeably healthier-looking than just a couple weeks ago, though not necessarily smaller. His chest, shoulders, and arms looked fuller and solid, and his legs had a nice pump. His once-lean abs were covered by some extra bulk, but Austin had told him he was on a bulking diet and needed to eat, eat, eat. “Sounds good, Austin. I’ll check in with you about my workouts every day like you said! If I need your help I’ll let you know,” Jon said, a bit of insecurity creeping into his voice. “Can… can you text me and call me every so often to check in? I just want to make sure I’m doing what you want and that I’m doing it right…” Austin walked over to Jon. He was several inches taller than his stepdad and much bigger and fitter. He patted Jon’s shoulder and noted how much firmer it felt than just two weeks ago. “Jon, of course I will. I’m going to help take care of you and turn you into a new man, got it?” Austin said, leaning down and looking his stepdad right in the eyes. Jon looked up at him and smiled, his blue eyes glittering, any kind of doubt washing away with Austin’s reassuring words.
