Part 1 The Hulk grinned as the human seemed to understand what he meant and wanted. He followed Richard into the other room, turning sideways to fit through the door frame. Even that wasn't enough however, as he felt his rock solid pectorals bend the metal frame to allow passage. "Human good. Human know what Hulk want." He rumbled, ruffling Richard's hair gently. "Now give it to Hulk." Now centered in the large lab chamber, Richard could see the destructive hole left behind by his colleague's enormous endowment. Turning his view to the other side of the room just parallel to the opening, he could see the still fresh discharge dripping down the wall. Such power he thought. The walls were at least half a foot thick of pure concrete and yet the giant could still puncture through with his erection alone. Going further might result with even more demolishing results... The Hulk huffed and stroked his endowment gently, panting ever so slightly as his erection and need continued to itch at his mind. "Human turn machine to full. Hulk take anything machine give." He grunted flexing an arm and admiring the sheer mass of his bicep. He slowly started to chuckle, edging closer to another release. He grunted and forced his hand away. He didn't just want to feel good, he wanted to feel great. The beam, the growth and the worship from the human would do that just fine. It was hard for the smaller man to think straight with Hulk so uncomfortably close to his being. He could already feel the scorching knee-low hairy sack of his titanic friend nuzzling against his lower lumbar. "Go over there and I'll turn the machine on", Richard said as he turned back to face his looming green partner. The Hulk grunted, walking further into the room, his shoulders hunched to allow his massive frame to fit into the room with ease. He pressed himself gently to the human, oddly enough enjoying the feeling of one too small being so close to him. "Hulk go stand, no tricks or Hulk smash you." He growled, tensing an arm in a vicious demonstration. He stepped onto the platform, surprised it could hold his weight, at least for now. He was happy to find he had a bit more headroom, at least he wasn't constantly hunched over. Each switch, dial and keyboard input was set to the appropriate setting. Richard swiped his hand over his forehead, wiping the sweat from his blushed face. His mind was racing at the possibilities of what he was capable of giving to his brutish assistant. it was hard for him to tear his focus off of the erect green hunk waiting for his next dose of radiation. He was immense already and that result alone was just from one single instance of radiation exposure. Not only that, the console's dial was still only set to the 1 setting. There were at least 10 levels available... "Why waiting! Hulk want!" The bellow, his body twitching eagerly. He growled as he adjusted his stance, preparing himself to feel the climactic rush, the growth, the building of overwhelming power within his body. He felt his massive shaft dribble eagerly, pre-cum leaking from his slit. "Hit Hulk with best shot!" Before turning on the machine, Richard adjusted the turn knob to the 2 setting, convinced that no matter what size Hulk would be, it wouldn't be enough for him. "Here we go..." He said under his breath as the scientist flipped the switch and activated the machine again. The machine hummed and buzzed, bathing the green giant in the highly concentrated gamma light. He threw his head back, groaning loudly as his body throbbed, flexing his chest as the radiation soaked into him. Wordlessly, he snarled and began to caress his body, his muscles and his cock. As he lavished himself, he began to feel heavier, his balls already hard at work, dropping lower and filling faster then before. It was a rapturous display being presented to the human. The build up was slow but the ecstasy was almost palpable. Richard could only stare on longingly, pinning his hips against the console as he too was hot and bothered from the Hulk's libidinous submission. "Human, come help Hulk! Hulk want to feel how big he is!" He chuckled as he widened his stance, his body eagerly resuming the slow growth from before as he filled his cock, slowly running a large palm along his titanic manhood. "I-I think I'll stay over here if you don't mind." Although as compelling as the offer stood, Richard had no intent to receive the same growing treatment. He had every intention to cater to Hulk's hunger for size. The Hulk growled, but understood. He was the very epitome of power, anyone in their right mind would be terrified to approach him. He grunted as his shoulders widened, muscles surging in size, neck slowly reaching up to swallow his head, only for his neck to lengthen and head begin to widen. Hulk panted, still focused on his ever growing shaft, caressing the thick veins that ran along its sides. Richard buckled his hips as he saw Hulk enjoying his ever increasing size. Licking his lips, the dial was then set to 3, the radiation pouring out more excessively now. Although it seemed as though the machine was slowly growing the monstrous man, its function only served to amplify the beast's sex drive. Each stroke of his hand pumped his frame to bigger and wider proportions with every caress more powerful than the last the longer he remained under the machine. His cock only hardened more and once his climax has reached and his member plush and soft again, the need to fill it with blood and pump will only worsen, practically making the giant addicted. Hulk let out a strained groan as his muscular mass increased at a quickening rate, every stroke, tug and squeeze of his manhood brought further growth to his frame. His steadily increasing weight bent the metal platform he stood upon. He shudders as his shoulders widened further, cracking his knuckles as he increased further in size, palms wider then a manhole cover. "Mmmmmore!! Hulk want more!" Richard wanted more as well. With no regret, the dial was switched to 4 as the spill of radiation continued to fan the flames of Hulk's sex drive. Naturally, the brute's body was further endowed to cater to his constant cravings. More curly hairs appeared across every inch of his body. His odor only enriched and invaded his nostrils with an exhilarating scent. Of course, even witnessing his very growth and massive musculature served to make the beast enraptured in bliss. The Hulk let out a bestial, primal roar as his growing passion was only further increased. It was maddening, consuming and mind-boggling. He furiously worked his shaft, oblivious to the hair sprouting along his swollen pectorals, between the deep crevices of his abs, tracing the near perfect horseshoe of his traps. He found himself widening his stand as his quads pumped full of raw power. He groaned and moaned panting and shaking. Richard only committed to their antics further. The dial went up to 5, then 6. 7. 8. He couldn't help himself. This was his only opportunity to see their experiment to its fullest potential. The scientist's eyes only widened at the sight of Hulk's massive arms raising and lowering, the biceps mashing against the pillowy huge pecs which flexed up and down into the grunting face of his partner. His cock was practically peaking past his head and his low hanging hairy testicles were bloating near the floor. It seemed like he was about to blow at any second. The Hulk could feel the building pressure throughout his body, from the tips of his sprawling toes to the very top of his dark forest cock. He shut his eyes and grinded his teeth together, fighting against the ever increasing climax that was building at the base of his cock. He roared and cried out, placing a hand on his tip, surprised to find his cock head was bigger then his palm. That moment of shock was all it took. His guard dropped and his balls pulled tight. Every muscle on his body expanded faster than his skin could keep up, making it look like his entire body was flexing. His eyes rolled back as he cried out, his shaft pulsating as thick jets of cum blasted from his tip through the ceiling. At that point, the trajectory of the discharge collided against the machine, damaging the emission of radiation above him to where no setting could hold back what was being expelled into the green monster. The mighty climax followed the same response previously, enlarging every facet of the Hulk's body at a quickening speed. Every hiccup his length made only pulsed his frame bigger. What cum hadn't escaped the enclosure only fell onto the giant. His cock had already punctured a new hole where his ejaculate carved out and his head was reaching to be next. Unleashing a guttural growl, the Hulk moaned and grunted as his body increased in mass almost uncontrollably. His voice deepened as the ceiling drew closer. Hulk bent forward as his back pressed against the ceiling, pulsating, stretching, thickening. Concrete gave way to flesh as he pushed up into the ceiling and through the building, pipes, wires, rebar and so much provided no resistance as his size continued to exponentially increase. The Hulk's head quickly vanished past the destroyed ceiling where his disproportionately enormous pecs were soon next to press firmly into the remains of the roof. What space was left inside the open chamber was quickly being filled with the titan's hirsute mass. Below his rocket of a cock, the vast pillowy sac was rolling outwards towards the scientist, finding any room it can to spread itself out. Despite being unable to see it, Hulk's ever thickening legs could feel the scorching hot balls overtake his stance, bulging between his limbs and underneath his taint. His loaded hairy ass had matched the protruding distance of his back, both pressing hard against the wall behind him with cracks forming against the aggressive swelling. The feeling of his body stuffed inside the crumbling confines of the room only catered to the Hulk's libido, making his impressive spire of cock shoot his loads even harder, more copious. His cock shivered, trembled and leaked like a river. Sweat rolled down his body as his bones cracked and snapped, expanding along with his body. The Hulk wordlessly bent down, pushing the roof out of the window, reaching down to grab the scientist that helped him. He smirked as he wrapped his hand around the puny human, hoisting him out of the soon to be destroyed lab. "Human help Hulk. Now Hulk help human." The green giant bellowed as he placed the man of science on his overly developed pectorals. Thirty feet above the ground, Richard could finally see what kind of experience it must had been for such an immense giant. Snuggly fit between the moist crevice of his partner's chest, the musk was the first thing to really hit the tiny man. Being so rich with hair and sweat, the smell of pure man was almost lethal. Still Richard welcomed such a beautiful odor even if was hard to breath at first. At last, being so elevated on top of his idol, he could gaze onto the dripping face of the Hulk, chiseled and stubbly with a vast jawline, shelf-top brows and toned cheekbones. His test subject was handsome, neanderthal-like but still beautiful in every way masculine. His head was bigger than the doctor but compared to his body, it was the smallest thing about him. Forcing his attention away from the titan, Richard looked behind him to see the Hulk's length stretching upwards, six feet above the Hulk's head. Its lobbing of semen had died down to a dribble as the growth was nearing its end. Hulk had his upper body freed from the facility, the hot Arizona heat now more apparent than ever. Aside from his shaft, everything below the Hulk's waistline was still inside the ruins of the central chamber. Hulk panted slowly unsure if the sweat permeating his body was caused by his sexual release, the mind numbing growth or the desert heat. All three maybe. He glanced down at the man resting on his chest, slowly grinning at him. It felt like hours since the Hulk's heart beat wasn't racing. He could hear his blood rushing in his ears, fading slowly. "Human... did good." He said, slowly raising an arm to better look it over. "Hulk happy." He brought his bicep up to his face, slowly kissing the emerald colored muscle mountain. Such a tease the dumb hung giant was. The deep moans and slobbering sounds of his tongue stroking his peaking arms gave the doctor quite a show. Although still horny, the amount of size the Hulk had piling onto his shaft had made the monolith slump down to its flaccid state, making the entire package rival to that of his entire lower half. The uncut cock rested against what ceiling was intact of the facility, keeping it from joining the rest of his member. The Hulk nuzzled his massive arm, almost needingly. It was obvious he was in love with his power and size. He moaned as his massive manhood slowly dropped down, brushing against the roof of the lab. The contact sent an electric tingle up the green behemoth, making his hair stand on end for a moment. He paused from his muscular ministrations, if only long enough to nod at the human and resume fondling his perfectly split bicep with his tongue. Having an arm raised just to grace the bicep, Richard couldn't help but also notice the curly hairs peeking past the pectoral landscape. The bush below his arm must have been stuffed senseless. Although the up close display was erotic beyond belief, the doctor couldn't help but feel as though he's missing out on so much more of this green stud. "If I was just on the ground..." "Human want down?" The brute asked, hearing the voice in his own head. He blinked as he tried to process the fact. He slowly reached towards the human, holding out his hand for Richard to climb onto. "Y-yes. Yes! I do!" How could this be? Amazingly the Hulk somehow knew what he was thinking. With his left half shifting slowly with easeless flexing, a giant beefy palm glided flat near the chest. With his bicep and shoulder shifting towards his torso, his pec in response molded itself up bigger. Everything about him continued to impress the scientist. Being appreciative, the little man jumped into the lumpy lift that was the Hulk's hand. "Hulk heard you say tho...." Hulk slowly lowered the human to the ground, looming over him as he lowered him down to the roof of the lab, the sunlight dancing lazily through his forest of hair, both on his head and the stubble along his broad jaw and chest hair. He stood back up, staring at the puny human and slowly smirked, the size difference between him was exciting. Below, Richard was placed directly in front of where the Hulk stood, right next to the fat flaccid cock that laid itself straight down across the roof's pavement. Looking up, Richard can see the Hulk having been nearly as wide as he was tall. "You knew what I was thinking?" Richard asked in a quiet voice. Hulk looked down at the human, ears too far away to hear what he said. He was hit by the thought a moment later then nodded. "Hulk heard!" He roared with a grin. "This is incredible!" It was unexplainable how the Hulk knew what the little man was thinking but the only real explanation could be a new super power birthed from the radiation he had indulged in moments ago. The Hulk didn't worry himself about the means of his abilities, like the little human was. He cared more about how massive he was, how thick his arms were, how absolutely titanic and grotesquely powerful he was now. His shaft stirred already, the vague thoughts of power, his power, already so intoxicating. "God you've gotten so big Hulk..." Richard put a hand up to the wall of cock, a pulse shook the surface as the scientist felt it pass through his digits. Even his feet felt the vibration shake through the concrete roofing. "Hulk didn't get big. Hulk got HUGE!" He roared with a crab flex, his traps and neck bulging out, his cock slowly rising off the concrete as his libido returned in full force. "You're right! Hulk IS huge! Hulk should show off more." The giant green behemoth slowly turned, exposing his maze-like back, muscle rippling and shifting, changing the pattern from one moment to the next The sheer turn of the giant's body left quakes along the facility. The blood surged cock, still soft, slid across the roof and fell lazily against the side of the structure. Richard was treated to a back, twenty feet wide and rippling, hair dusting across the surface as it shimmered in the beating sunlight. The ass however was closer, a mesmerizing combination of solid fiber-like muscle and round fatness. Its size almost rivaled that of the back, mere feet away from touching the upper body completely. The crack was stuffed to the brim in hair, unsubtle in it's presentation. "Wow..." was all Richard could muster up. The Hulk guffawed, rolling his deeply striated shoulders, back rolling like waves. His arms rose as he growled, pumping out a titanic double bicep flex. The Hulk knew the human's eyes were glued to him, his planetary glutes, the sweep of his hair and the sheer mass of his body. "Hulk know what human want! Human want Hulk." His booming voice echoed across the empty canyon, announcing the desire Richard had for the green behemoth. There was no hiding it. He knew what the little man was thinking. Richard's pornographic thoughts were completely laid out for the Hulk to revel in. It was almost reverse psychology as Richard couldn't keep himself from hiding his hottest dreams. The forest colored giant slowly placed a hand around his massive shaft, lavishing his dark green tip slowly. This was what that tiny speck wanted. To witness all of his sexual glory and obscene might. He rumbles softly, shaking the air as he did so. “Little man like it when Hulk go slow, when Hulk make sure little man sees everything.” He cooed teasingly, slowly lifting his other arms up and behind his head, fighting his own mass to do so. Having Hulk reward the tiny human with a visage of manly captivation almost seemed generous to Richard. Although having the godly mountain of man do anything but pleasure himself would be illogical. The experiment had already made sure that Hulk's sex drive was at its apex and seeing little Richard's visions of his green master ascending higher and flaunting carelessly only turned him on even further. Hulk smirked, loving the attention, the thoughts directed at him knowing exactly how much space he took up in the tiny human's even tinier brain. He growled and pumped his arms and stared down at his massive, planet sized biceps. His cock throbbed and tensed. The Hulk reached out and gripped his shaft, working his shaft with both hands, moaning loudly. "Ohhhh yessss big Hulk, feels good... So good!" If the outside didn't already leave the two hot from the sun, Hulk's cock-pumping workout would have surely reproduced the same heat. The sweat piled on, pouring from every hairy orifice on the giant's body. With his cock already craning back up past his head, the slick burly hands started up his growth again, his pleasure fueling his size. The ruins of the building around his figure were but an afterthought to him, crumbling feebly as his growing body collided against them. Richard, still on the partially destroyed roof, watched in awe. "Yes, that's it! Keep growing Hulk!" The behemoth grunted and grit his teeth as the full body pressure of growth began once more, he screwed his eyes shut, working his monster shaft eagerly, His colossal pecs heaved and bounced as his hands worked his titanic shaft, he howled and panted, working his growing shaft harder and harder, faster and faster now. "Work that cock big boy! Show me just how big you want to be!" Richard egged the monster on. His mind raced and conjured subliminal images of Hulk twice as big, three times as big, catering to the hunk's bottomless cravings. 45 feet came and went with a cock past even that. Hulk's height carried his hairy balls up in full view for Richard to see though at this point, the poor human couldn't even see past the length of his god. Being so close, the smells had already made the human light-headed, sweat raining down on him, making the stench he loved so dearly permanently stuck to his being. "Guuwaaaarrrr!!! Hurrf hurrf!" He snarled and roared as his shoulder grew further apart, making space for his neck muscles to balloon out, almost swallowing his head completely. He licked along the tip of his thick cock, his flesh quivering and bulging faster now. "Hulk feel... like he gonna!!!" He cried out, the pressure growing faster now, the feeling of growing, strengthening, muscle piling on top of muscle mixed with the absolutely pleasure he way forcing into his cock was mind numbing. The man's eyes widened. His feet could feel tremors passing through the soles of his shoes, signalling the Hulk's next explosive surge in size. Having reached the fifty foot mark, the expansion would surely push against the rest of the facility, along with the smaller scientist. Still wanting to live to witness his partner's ascension, Richard bolted across the rooftop to find a ladder down before it was too late. Turning away, he could only hear moans, grunts and rumbles, the Hulk's shadow casting far from his position. Unrelentingly, Hulk couldn't keep himself from slobbering against his fleshly pillar, desperate to get his fill of sex in before he'd ultimately have to start over again. "Ah... ahhh! AHHHHRRGGG!!!!" Instead of feeling the sweet release of orgasm, The Hulk's growth once against flew out of control. Muscle exploding in size, limbs lengthening to make space for the new tons of flesh. "Awooorrgg!" He flexed, tensing his bulging pecs, admiring the slabs of flesh as they stayed swollen, only increasing in size as he tightened his 10 pack, releasing them. His biceps stretched out, almost tearing his skin. Hands and feet exponentially increased in size, hair covering everything of newly formed skin. Finally reaching the earthy ground, the shadow Richard saw before could be seen widening and stretching further away. He ran out into the open, away from the destroyed facility and turned as he did to catch a glimpse of the heaving heavenly hunk soaring higher. Testicles now matching the Hulk's own width demolished the building with its own size, concrete breaking away meter by meter, hardly an obstacle to the massive cum tanks. Richard stopped and turned, seeing the cock head bubbling and frothing as it was ready to make its first shot.

From a roleplay I'm doing with a friend. There's been a lot more written so keep an eye out for part 2 later on. The series includes, muscle growth, hyper and macro. It was mid afternoon deep in the Arizona desert. Doctor Banner had been out in this isolated lab now for the better part of two years, working out how to make monsters out of men. Improving the military's selection of men and surpassing the limits of human biology. anything to get a leg up on the looming danger of foreign agents. Rumor was they too were working on something similar. He was currently standing in front of a large computer console, adjust a vast multitude of dials and switches, adjusting his math on the fly to accommodate the varying inputs the system was being fed. "Alright... I've regulated the output and the correction algorithm is steady. I hope your math was as good as you say." the beanpole doctor said, his voice a little nervous. He trusted their work, but facing down the emitter itself was a little nerve racking. "Have faith Bruce. You've seen the numbers so there's no reason for doubt. After we succeed in the tests, you and I can finally get out of this place. I'm not taking any more delays just because the military can't decide on who should be their test subject." Although Richard was completely committed to seeing his work finalized, he too couldn't help but feel anxious going through with the final trial. After all, it was Banner's idea to take the test but the experiment was almost too good to be true. Banner might really be the next superhero in the world, but even then, what would that spell out for the rest of the military. "I know, I know. I'm human. Doubt always lingers, even when facts show there is nothing to fear. We see monsters in the shadows at night." Bruce sighed, adjusting his glasses gently on his face. The concept of super human powers was extremely glorious. His brain and the brawn they were artificially creating would be a tremendous force for good, as long as he kept his morals. That's why Richard was around. "Everything is set over here, how're things with the emitter module?" "As good as one can expect. Just step onto the platform and we can get started. I'll give you a minor dose and from there we can witness the results." "Right, base of our simulation resulted... At this dose my shoes should be tighter, but nothing else." he said taking off his glasses and setting them down somewhere safe. He left his lab coat on his chair as he walked over to the patch job platform they made. "Ready!" From the console, Richard turned the dial clockwise to setting 1. An audible hum buzzed above Bruce as the dish-like machine was being fed the appropriate power. After typing away on his keyboard, Richard set his hand onto a large switch mounted to the console. Looking up, both men saw eye to eye in anticipation. "Here we go..." "Alright. Lets play god!" Bruce shouted, giving a final thumbs up as the machines whirred and buzzed around him. Even though the voltage was low, the machine was rather dramatic. The switch was flipped. Visible green distortions in the air could be seen whirling around Banner in an instant. Although the machine was clearly working, the ray of radiation had no bearing on Bruce. Despite being affected, the only thing he could truly feel was a light headed sensation. Bruce winced gently, looking at the green flickers and glittering around his body. He looked at Richard's blur and shrugged. "Doing good." He shrugged gently. A good minute had passed and eventually the switch was flipped again. Richard could see Bruce completely untouched by the event. Although expecting noticeable alterations in Banner's physical appearance, super powers can sometimes be hidden away and thus further examination was necessary. "Well... for all the sound and spark the machine gave off, I feel relatively the same. could you hand me my glasses?" Bruce said, carefully stepping down from the platform. He wandered over to Richard's blur, wondering if he looked any different. "Well Bruce, you don't look any different, but we never really expected that much to change on a physical level." Richard reached out to hand Banner his glasses. "How do you feel?" "To be frank. Light headed and annoyed. I'm concerned we may have to go back to formula." He frowned as he slipped on his glasses. He shifted gently, his clothing felt a little off to him, but perhaps it was the treatment. "We may want to do this nude next time. My shift feels starchy." "Don't be so hasty. You might have gained something after that kind of exposure. We can't risk another dose until we know what's changed. Are you sure there isn't anything about you worth noting?" "Hmmm nothing of notice right now but I see what you're saying, give the treatment time to work." The doctor nodded as he slipped the lab coat back on as well. Bruce picked up a clip board going over the questions, post test. He shuffled a little, feeling a little warmer, but nothing concerning. It was later that day lunch had just past and the sweltering heat of the desert was rising steadily. Bruce was sitting at his desk in the lab, slowly pouring over their calculations, theorems and various documents and tests. By this point in time, he felt that something should have happened, there should have been a change, yet nothing at all. He kept his calm however, this was the first trial on an organic creature they tried. it wasn't a set back. Soon there'd be a swath of overly grown men, charging across battle fields. He grinned at the idea. heck if the test had worked, he would have been one. He felt his cheeks grow warmer as he pictured himself at superhuman sizes. Bruce coughed gently as he got up to answer. He twisted the knob and pulled it open, harder then he expected. "Yes?" He asked. "Sorry to bother, it's just been several hours since the experiment and I wanted to know if you've come to any conclusions yet on the test." "Nothing yet, I apologize." Bruce said to Richard, inviting him into his lab. Bruce found himself adjusting the AC in the lab, lowering the temperature further as he felt even warmer. "Warm today, isn't it?" He began to prepare the coffee machine. "Did you find any breakthroughs?" He said as he shifted his stance a little. Richard gave Bruce a puzzling look. "Nothing to work from I'm afraid. I will say, you have this room freezing cold right now. Are you sure you're okay?" "You find it freezing? I'm feeling really warm" Bruce huffed and sat down at the lab desk once more, stretching himself. "I kind of wish it had work though..." Richard leaned on the desk next to him. "It's hard to say. Maybe genetics are a factor. After all, you're the only one we've tested. I suppose we can try another dose later." Richard looked at Bruce and noticed sweat marks around his work shirt. "If you had these powers, what do you see yourself doing?" "Hard to say, but it would make assembling labs a lot easier." Bruce chuckled, slowly starting to day dream about hoisting large lab machines over head, being built like a tank and just... so big, so colossally huge. He didn't even notice his hand lowering down to his crotch, caressing his cock gently through his pants. "I can't imagine it being wide spread through military interactions. So many men getting that treatment. One can only imagine what life would be like living with such power on a daily basis..." Bruce nodded and chuckled in agreement. "Men the size of giants, walking around, training, maybe it would spread into the general populace," he smirked as he felt his manhood harden in full."God i wish it worked on me." He moaned softly, squeezing the fat head of his manhood. "I don't think it would-" Richard paused after he heard the rustling of Bruce's pants. "Banner what are you doing?!" Bruce was a little lost to his growing lust, slowly working his shaft out of his pants. "Sorry Rick, i just... really need to take care of this." He muttered, almost admiring his decently sized manhood. "Something had happened to you hasn't it! I mean I know it's been a while, secluded and isolated but where's your decency!" Regardless of his outcry, even Richard was impressed how fat Bruce's uncut malehood was. "I'm nowhere near the projected results. I think its just cabin fever..." he grunted, slowly letting Richard admire his manhood. From the few choice veins running along the shaft to his thick, fat glands and the green tint slowly spreading over it. "W-What's happening!?" Richard was in awe as the pinkish skin tone of Bruce's junk was slowly changing to a dark green hue, but it wasn't just Banner's cock that changed, even his skin was gradually shifting to green as he pumped his dick over and over. Bruce huffed and panted working his shaft faster now, the green spreading. His cock was slowly stretching, pulsating, enlarging between his fingers. "Uhhhfff Richard... I think... something's happening." The scientist backed away slowly from Bruce, witnessing the changes overtaking in his body. The masturbatory arm locked into a flex was noticeably bulging inside Bruce's tightening work shirt. His neck filled the collar, veins creeping out as his expression grew more intense. For every push and pull of his growing hand going up and down the enlarging cock, Banner's form only widened, clothes filling with his mass. Banner could feel the changes overtaking him, at this point he welcomed it, flexing and relaxing his masturbating bicep, watching the muscle swell and relax, then swell even larger. He could feel his shoes growing tight around his feet, his shirt struggle to stay clasped. he couldn't help but begin to laugh. His tongue hung out as his belt gave way to his widening hips. Bruce's bellow sounded almost deeper than his regular voice. Richard was still in awe, absolutely paralyzed and yet, overjoyed in some way. "My god Bruce, it actually worked!" Bruce was too far gone to hear what Richard was saying. All he knew was that he felt good, wanted to feel even better. He dropped his cock for a moment, brought both his arms up slowly, and pumped his biceps into twin peaks. Thinking was hard now, his mind addled by the sheer rush of power from his entire body. "Big now. Getting bigger!" Each ball of muscle tore seams across his long sleeve shirt. His hard cock stretched to a foot in length right in front of the flexing behemoth, twitching in wait for his touch. The brute that was Bruce had gained a foot to his frame and even the chair creaking and groaning suggested he had put on a tremendous amount of weight. All of this started just from Banner being hot and bothered and even as he sat there, hands off his meaty cock, his growth slowed to a crawl. Maybe masturbating really did set off a chain reaction. "Bruce, I can't believe I'm saying this but, I need you to... to keep touching yourself." The massive brute huffed and eagerly continued to work his shaft. He didn't need a puny human telling him what to do, but it seemed he enjoyed the show. The green monster couldn't help but flex while he continued to pump his monster cock. "Puny human, like what you see?" Of course Richard liked what he was seeing but did Bruce really not know who he was? "Banner, it's me, Richard. You know who I am right?" Richard said all the while the green behemoth continued fondling his girthy length, his body growing continuously as more rips and seams formed across his clothes. The growing hulk grunted as he opted to stand, his feet bursting through his shoes as he suddenly increased in height, grunting as his muscles expanded in a rapid burst, his shirt tearing and bursting as his muscles expanded further. "Hu-Hulk can't stop! Hulk want morreeeee." Richard fell backwards, staring up at the growing green giant. He stood at eight feet, clad in nothing but loose torn shorts made from his pants, already on the verge of breaking as they held his filling balls. Veins traveled across his hairy physique, sweat dropping like rain as droplets zig-zagged around the curves and crevices of his muscular body. Hulk radiated with such an immense heat, still pumping his loins as he inched closer to the ceiling. "H-Hulk?" Richard could only question the new name of his partner. The green giant roared and flexed, all but tearing the last vestigial remains of his shorts off. His balls dropped with a pleasant bounce, bringing a blush to the huffing brute's face. "What?!" He barked as the man called out his name, he stepped toward him, his muscles moved in tremendous harmony, like semi trucks maneuvering around a parking lot. Hulk grit his teeth and growled. "What human want from Hulk?" Richard had to constantly crane his head back to keep the approaching Hulk in view. He stood uncomfortably close with his foot and a half prick poking against the scientist's chest, smearing pre into his work shirt. Richard continued to gawk up at Hulk, his heat and odor getting to his sensitive senses. Without saying anything, Richard put both of his hands onto the Hulk's shaft, slowly moving his palms back and forth, the deep green foreskin stretching and pulling back. The Hulk snarled growing impatient moments before the human's hands were upon him, slowly working his shaft. The big green man placed a hand on the wall to steady himself. He licked his lips and moaned gently as his shaft was working. "H-hulk feel good. More! Hulk want more!" Sweat formed on Richard's face as both the heat emanating from the Hulk's body combined with the lingering expectations expressed by his oversized partner. Never before would he have imagined himself in this situation, his lab assistant several times bigger, enraptured by sexual acts conducted from both curiosity and fear. Nevertheless, Richard picked up his pace, pressured by the brute's anticipation. The Hulk groaned and placed his free hand on Richard's head, stroking him gently as the man pleased him. The green giant felt a rise in pressure through out his body, drawing several long growls from him as his muscle inflated further, straining his emerald skin as his grip grew stronger on the human's head. Each stroke served to separate the smaller scientist's hands apart from each other as the shaft pushed up and out. He was growing. The stimulus from each masturbatory act only fueled the beast's power. Ever so slightly did the Hulk's shoulders bulge horizontally, chest furl forward, legs thicken in every direction, feet and hands scaling to larger sizes. His head remained almost untouched with the exception of his jawline growing bulkier, his brow shelving and cheek bones more pronounced. His overall appearance was made manlier. The growing brute felt his power increase, his body take up more room, his figure growing more and more imposing. his shoulders grew further apart, granting more space for his muscles to expand into. His musculature bulged under his skin, as deeply striated and detailed as the support cables for a bridge. He smirked down at the human, as he grew smaller and smaller. He felt his balls slowly drop down, swelling as his seed filled them, almost to bursting. Witnessing the scene of his colleague, brutish and virile, growing right before his eyes had ignited even the doctor to sink deeper into his love-making. Eagerly, Richard pressed his lips against the smelly underbelly of the green cock while his hands pushed towards the back side of the stiff tool, lathering the meat with his tongue. The smells, the taste, the increase in flesh and splendor, all of it left the two intoxicated. The growing brute cried out with each wave of growth that radiated out from his massive shaft. the smaller hands, the warm tongue and the sheer physical pleasure of this transformation was growing to be too much for the Hulk. "Hulk gonna... Need to cum!" Suddenly, Richard noticed the Hulk's involuntarily growth had ceased, replaced instead by a shaking sensation that tackled every foot of the green brute. He stepped away slowly, as if anticipating a bomb ready to go off at any moment. Hulk roared and grabbed his massive cock, working it furious as his felt his balls tighten, muscles deep inside him sprung to action as his hips involuntarily thrusting his shaft into the wall, pounding through the concrete until at last, release was granted, his thick seed shot out in pulses as he let out a guttural roar, flexing with all his might. His growth suddenly returned, his head slamming into the ceiling as his body expanded faster now. cords of muscle growing discordantly. He stared at the hand gripping his manhood, watching as his fingers ballooned one by one, his palm widened to match, knuckles popping and rising like mountains. He hissed and snarled as his other hand, curled into a fist grew to match. Hulk... feel HUGE!" he bellowed. Slowly, the orgasm subsided, the giant green man panted and rubbed his head, and slowly looked himself over, admiring his new mass and size. "Human... make Hulk feel grow again." he growled. Richard stood behind him, jaw dropped as he stared on at the miraculous presentation of the Hulk's fuzzy backside. So many muscles were shifting hypnotically from the simplest of movements. Richard's eyes widened in excitement when he looked below to see such an enormous ass, strong yet plump with curly hairs sprinkled between each cheek. Even below that, the Hulk's mighty testicles hung low between his legs, bigger than ever, reaching just below the knees and hairy, like the rest of his frame. The Hulk slowly turned to Richard, his brow furrowed in annoyance, his eyes deep in his skull now, as his brow had expanded tremendously. As he turned, the other scientist would get a clear view of the perfectly sculpted delts, his triceps and striated lats. His bicep slowly swung into view, as large as a car tire. His pecs followed, each globular mass jutted out from his chest like the peaks of a mountain. Across his body grew the gently curled, black hair. His lantern jaw was dusted with a healthy 5 o'clock shadow. Despite the perfect spectacle of throbbing muscles, sweat and hair, the Hulk's presentable turn brought forth an even bigger cock into view, growing flaccid now but thicker and bigger than before. The width could match even his hulking legs that draped in front of his titanic sack. Just how big could Hulk get? Richard could barely even process such a size. "Human no hear Hulk?" He grumbled stomping forward towards the man, cock swinging from side to side leisurely as he walked forward. "Human!" Shaking in fear, all Richard could mutter was "Y-Yes?" The Hulk started to fill his sight as he approached, a twelve foot muscle bound giant approaching, hunched over with abs of steel flexing and his traps carving indents into the concrete ceiling. The Hulk struggled to move at times, dragging his rising traps through the concrete roof, shaking the dust off his shoulder. "What happened?! How Hulk... grow?" he asked, sounding genuinely curious. "W-well Hulk, you're....hammer right there", Richard raised a finger pointing to the enormous girth between Hulk's legs. "That make's Hulk grow..." "Hammer? Hulk no have hammer. Have fists!" he growled, holding one out for Richard. "See! Better than hammer, stronger." He unfurled his fingers gently, his forearms rippling as the muscle pulled his ligaments in a synchronized dance. "Hulk remember though. Making Hulk feel good made Hulk grow. But Hulk remember... light, green, made Hulk! Get light, Hulk wanna see if it make Hulk Hulkier." "A light?", Richard asked questioningly. Perhaps he meant the machine. Green radiation could be the green light. If one dosage made him this big, what kind of an effect would another do to him? Regardless, Richard was almost giddy picturing the Hulk at a giant's size. After all, it was a discovery, a scientific discovery. He was ready to discover just how big man could be. "Hulk follow me" he said to him and walked out into the next room where the experiment took place. Part 2

This was part of a collaborative roleplay I had with Arribous that we never finished. I found the whole thing to be hot and well written and I've always enjoyed Arribous' writing style. Hope everyone likes it. The scenario features a would-be villain attempting to sap away Mr. Incredible's super strength only to find that things go awry. Contains hyper, macro and some sexual scenes. "SO! Mr Incredible, we meet at last!" Bob heard the voice emerging from the darkness of the large, echoing room. His arms and legs were stiff, stuck in place as he felt suspended in air. Dramatically, fluorescent lights flickered on as the interior was lit, showing the warehouse in its entirety with shelves stacked against walls and a man standing before him. The figure wore a black jumpsuit with leather straps wrapped around his body. Bob turned to see what was restraining him as he noticed the two generator-like machines to his sides, buzzing loudly as they work to keep him trapped. Both wrists and ankles had been latched to metal plates with a noticeable blue energy surrounding them. He was left with both arms raised over his head, as if he had been shackled in some kind of dungeon. "What a pleasant surprise it is seeing you here. I didn't think you'd be so foolish to just waltz right through the door but now here you are, hands tied by my magnetized machine. I applaud your efforts." He didn't remember how he'd ended up like this, it was supposed to be an easy job that he could handle on his own. All he remembered was arriving at the warehouse...and then he ended up here. He knew his head was killing him, the middle-aged hero groaning and pinching his eyes closed as the ringing in his ears started to fade. "Ugh..." he groaned, shaking his head. He tugged at his restraints, testing them, finding that since they weren't physical objects he could overpower, he was stuck here. He sighed, hanging his head, an annoyed expression on his face as he looked at this...interesting individual. "Who're you?..." he grunted, not familiar with this person "Why I am Dr. Grow of course and you my friend are the very enticing Mr. Incredible. I've kept my eye on you for some time now." The masked villain said as he gave a slight pinch to his mustache. "Your superior strength is a fetching trait I hold much respect for. I'm almost jealous of it. I AM jealous of it." He turned away, giddy at the reveal of his master plan. "Brains aren't enough for me anymore. What I want is what you have." Bob sighed, furrowing his brow. He didn't have time for this, this was some two-bit hack that the police force shouldn't have any issue with. "You don't think a gym membership would have been easier than capturing me?" he said with a smirk, not particularly concerned. He didn't think this guy had much up his sleeve that could hurt him. "Oh believe me Mr. Incredible. What I have will make gyms obsolete! BEHOLD!" With a dramatic turn, Dr. Grow revealed his weapon. "This my burly friend will be the end of your super days: The Drain Gain!" The small ray gun was sleek and appeared comically canon to weapons of science fiction. "This little tool will suck the brawn right out of your body, harvesting your heroic muscle so 'I' can live in your shoes." The slightly-pudgy superhero was more curious than he was afraid, there was no way that this guy could drain his super-strength, right? Even if he got smaller, he'd still be able to draw upon his massive strength reserves whenever he needed to. He let the wannabe super villain boast about his device, remaining silent and waiting for an opening, his eyes darting around the room behind his mask as he looked for anything that could help him escape. "But why explain it when I can just show you." Giggling maniacally, Dr. Grow had switched the device to the first setting, aiming the Drain Gain at Bob with glee. "Any last words before I make you obsolete?" Bob grimaced, gritting his teeth a bit. "Once I'm out of this thing, you'll regret what you're about to do," he cautioned him, despite knowing it'd fall on deaf ears. "Do your worst." With the pull of a trigger, the weapon blasted a ray of green energy at the helpless hero, encompassing his form in an emerald aura that tingled his skin. Dr. Grow, smiling wide, looked on with excitement, desperate to spot the effects taking place. The process was slow and hard to notice but unbeknownst to Dr. Grow, his choice weapon was having the opposite effect. Even to Bob, he was convinced the alien sensation was taking a toll to his powers yet his figure sluggishly swelled. Bob grit his teeth as the ray hit him, expecting something painful...but he cracked an eye open when he didn't feel a blast of pain, only a strange tingling feeling working its way through his muscles. His suit creaked softly as the mass beneath it began to slowly expand outward, the hero instinctively flexing his muscle as best he could, given his position. The metal clamps around his calves and forearms were starting to feel rather tight. Slowly, Dr. Grow's smile was beginning to sink. At that point, the growth was noticeable to him. Bob's biceps had started to slowly swell closer to his face. His visible lats were wider, thick thighs even thicker, chest size growing, pushing out more. Something was wrong. Releasing his finger from the trigger, the growth had completely halted as the Doctor had disappointment written across his face. "Uhhh...give me a second here." Bob snickered, looking down at himself, his pecs having grown a bit thicker, his biceps tugging against his suit a bit. "Heh. Seems your little toy there might actually be useful. I think it grew me bigger...Maybe you need to turn it up some, maybe it'll work then," he said with a coy grin, hoping that the maddened doctor would go along with it. Maybe he'd get strong enough to break out of here. "Be quiet you! It's just a bug, nothing more..." As he examined the gun, Dr. Grow noted the setting set properly to drain. Perhaps down the line, his configuration functioned in the exact opposite. Switching the setting to gain, his confidence returned once again. "Now Mr. Meathead, watch as your new muscles suddenly vanish!" The beam struck him just the same, and the same effect happened. His muscles slowly swelled, his body getting thicker, wider, heavier...but since the machine was calibrated to only hold someone of his mass and not a larger person, his levitating bindings began to wobble, starting to let him drift down towards the ground. Seeing his opportunity, Bob grinned and began to struggle with the restraints, trying to do whatever he could to get out of the field's effect! "No! Stop!" Dr. Grow's attempts to remove his finger from the trigger hadn't stop the gun. The trigger was stuck in the active setting. No matter how hard he attempted to point his gun elsewhere, the stream was already too familiar with Bob's body. The magnetic machine was starting to groan. The added weight of Bob's mass was overloading it's field of influence. Bob was looking quite beefy now, his frame tumbling forward out of the machine's stasis field, falling to the ground and getting to his feet. Now that he was free, he quickly plied his strength to rip off the shackles around his wrists and ankles, freeing him from the device's grip permanently. But still that beam continued, his shoulders widening, his pecs flaring out in front of him, his glutes more defined and thicker beneath his suit. He grinned cockily, reaching up to flex one of his arms, grunting approvingly. "Whoof. Nice...don't suppose this is permanent, eh?" he chuckles, rubbing his arm. Prying the trigger with both of his fingers, the device finally went off. Now that his focus was on Bob, he stood stunned to see the hulkish hero, seven feet tall, almost seven feet wide. The sudden burst of brawn and beef had left the doctor scared. The moment was so perfect and now his plans had been thwarted on his own accord. And then there was Bob, holding his attention captive. The silk-like red suit stretching enough to show a hint of skin. The "I" insignia adorning his chest was pulling across his hefty breast. Even his black tights had a noticeable heft between his thighs. Dr. Grow was not only afraid, but intrigued. Bob took advantage of his opportunity, lowering his arms and flexing his biceps against his chest with a grunt and a broad grin. "Grrrh! I'd say that's a hell of a little toy you got there, doc! I think it about doubled my mass...look at me, heh," he chortled, relaxing his muscles and idly bouncing his thick pecs, a near-hypnotizing motion for the doctor. "What do you say about pumping me up a little more, eh? Even me out some? You've got scientific curiosity, right?" "Don't think this is over!" Dr. Grow said with a shake in his voice. "Just because you're some Adonis with...flawless arms and chiseled abs...and..." His concentration kept falling victim to the perfect physique he had crafted. "Laugh now, because I'm still going to drain you of all of that." The Doctor was lying of course. Even he knew that his weapon had no effect to suck the powers from his adversary. That still didn't stop him from holding his ray up and pulling the trigger, knowing well of his defeat. He might as well enjoy seeing his victor become even more irresistible. Bob ran his hands down his abs, touching every finely-contoured line, rumbling his approval. "Mmmmm. Even got rid of my pot belly too, heh. It might even help my hairline grow back," he chortled, raising his arms up and flexing, flaring his back out as wide as it could go. It was during this flex that he was struck with the beam again, which made him laugh deeply as he felt his body start to swell outward in every direction, gaining height and muscle and even more mass between his legs, the crotch of his suit stretching and deforming around his swelling manhood! "Rrrrghh, that's it! Keep it comin'!" he barked, his voice growing deeper and louder as he grew. Two feet was added to the glory of Bob's body before Dr. Grow stopped his gun again. The sheer arrogance of his nemesis toyed with his libido, drawing his enthusiasm towards his form. He approached Bob timidly, still pointing his weapon at him. "You like that don't you? You like being my lab rat." The doctor stood a few feet from his manly creation. He could see damp spots below the shoulders and around his chest. The smell of man was unavoidable, even at his distance. That suit; amazing that it still managed to keep itself around the curves of each bulbous muscle. He was even more amazed at how the ray was affecting the hero's member. The outline of his cock and balls had made his junk so apparent in the black speedo. His Drain Gain was never intentionally made to affect such an area but to the amusement of Dr. Grow, he wasn't complaining. Bob's hands reached up to grope and heft his newfound pec-shelf, a manly grunt of approval rising from his throat. "Hrrnnfh...I like getting bigger, and stronger. And you seem excited to give that to me. Maybe...you always wanted me so big and huge and hung, eh?" he chuckled, reaching a hand down to shamelessly grope at his package, the soft cock as thick as his wrist and so long it was forced to curve forward and below his nuts inside the stretchy confines of his suit. Sweat was starting to pool under his suit, soaking into the water-resistant fabric, beads rolling down his face as he panted and groaned under his newfound bulk. Dr. Grow almost pawed at his figure, fixated on giving it a touch. He was still frightened, fearing his worth drain with every blast, yet he still wanted to fire at him. "Tell me big boy, how desperate do you want to grow?" "Hahaha," Bob laughed, turning to the side for a side-chest pose, grunting as he flared his incredible pecs outward, tensing his bicep against them. "You say that like there's any outcome aside from you blasting me again. But I'll humor ya. I wanna GROW. REALLY huge," he grunted, his voice carrying a lot more presence now. "Give it to me." The desire for growth almost worried him more but his attitude suggests he doesn't take the villain serious enough. Nervously, Dr. Grow replied: "First, you kneel." Bob chortled, shrugging his massive shoulders. "Heh, yeah, why not?" he grunted, a little caught up in his growth himself. He dropped down to one knee, still looking down at the shrimpy doctor, though not quite as much as he had been a few moments ago. "I'm waiting," he grunted in mock annoyance, the heat from his body radiating off him like sunbeams. Dr. Grow's heartbeat was racing. He was actually complying to his demands. "Raise up your arm", he asked, hoping the loyalty was still present. It was never really there to begin with, Bob was just playing along so that he could grow bigger. He raised his arm as bidden and flexed, the bicep peaking up enormously, so tall that he could rub his knuckles on the top of it! "Hah, like this?" No reply was made. The glorious mountain of arm was a sight to behold, yet the bothered doctor had his interests below it. He crept closer to his pit, breathing heavy of its aroma. The already sweaty face of Dr. Grow was moistened further by the damp surface of the lat. He only continued to close in further towards his body. If Mr. Incredible can enjoy his newfound size, why couldn't the doctor? Bob grinned wolfishly as he realized what the doctor was getting so worked up about, the scent radiating from his pits, cascading down the inside of his suit, his man-stink leaking out despite the tight elastic contours of his suit. "Heh, you like my smell, doc? Y'know, it'd probably be a lot stronger if I grew big enough to rip out of this thing. But it can take a lot of stretching, so I'd have to get pretty damn big." "And big you will be, once I'm done with you..." The doctor leaned into Bob's side, face pressing against the cavernous contours of his pit. His tongue rolled against the fabric, the musk unbelievable to his senses. One hand caressed the side of Bob's chest, grazing against the protruding nipple under his suit while his other hand felt the lumpy surface of his flaring back. Above him was the mass of Bob's arm, still dripping on top of the wimpy doctor. "Grrhh...yeah, get a taste of a real man," he grunted, tensing his fist and flexing his bicep and lat and pec as strong as he could, the exertion causing the sweat spot to spread further, his musk invading the doctor's nostrils even more fully, he felt Bob's incredible, spicy male-scent reach into his lungs and brain! "Mmmnf, lick my pits more, taste my manhood little guy!" Dr. Grow obliged, lathering every inch of Bob's pit with his mouth. While he tasted the super beast, his arm reached for his ray gun again, unleashing another wave of growth while he savored the salty taste of man. Bob closed his eyes and groaned low in his throat as his nine-foot frame began to swell and bloat upward and outward once again, his muscle creaking beneath his suit as it grew bigger, thicker, stronger. He didn't even know how this might interact with his powers, but he had no doubt it'd make him exponentially stronger! His free hand reached up to heft his pecs, fingering the meaty nipple beneath the suit with a groan, sliding his palm down his bulging 8-pack of abs, feeling the Adonis belt he'd grown under his fingers...he was getting so BIG now, he had to be more than twelve feet tall, looking like he weighed two tons of musclebound brawn! The suit was still holding, but who knows how long that'd keep up. Stopping his ray gun again, Dr. Grow dismounted from Bob's soaking pit, stepping away as to fit every inch of sweat soaked muscle into view. Mr. Incredible was a titan. It was amazing how much room had vanished from his presence. Seeing his deep red suit turn pinkish, stretching from how much muscle it had retained inside only made the doctor tingle. All plans of sapping the hero's muscle were burned away by the villain's libido; the results were just too good. There was still so much room in the warehouse for him to continue and he saw no reason to stop soon. Still, he enjoyed toying with Bob. Any power he had over him was dictated by him giving Bob power. He was all too excited to continue his game. The hulking blonde superhero grunted, flexing his biceps against his chest, leaning his head back against his swollen traps, a broad and eager smile on his face. "Mnnnf. How do I look, Doc?" he snickered, raising both of his monster biceps and flexing them with a growl, the twin peaks of muscle forcing his forearms to bend outward. "Look at me...look how WIDE I am, haha! I feel stronger than ever!" Indeed, Mr. Incredible's physique was pushing to freakish levels. The enticing flexes and soaked suit only played with the Doctor's composure. "Yes, you've certainly grown quite a bit, but you're still too weak, wouldn't you agree?" his eyes fixated on the knee hanging clad member. Bob nodded eagerly, smiling brightly and relaxing from his flex, looking down at the doctor and looming over him, now more than double his height and hungry for more. "Oh yeah. I could stand to be a LOT bigger. I dunno what kinda freaky beast I'm gonna grow into...but I can't wait to get there and find out!" "Then you'll be a good little hero and let me... inspect your changes." The doctor's voice was breathy and dry. He crept closer to the heaving mound of cock, wrapped snugly into the distended leathery tights of Bob's suit. The member had grown to half the doctor's size with the leg holes extending on the sides to show the pink skin wrapped away by his red suit. The pouch was incredibly moist and musky and the smell only intensified the closer he came to it. From his perspective, he could see Bob's face slowly falling into obscurity behind his pumped up pecs. Both of his hands caressed the bulge, tiny in comparison to its magnificence. The balding demigod moaned happily as he felt those tiny hands on his massive dick, grinning from ear to ear and reaching forward with one of his huge hands, gripping the doctor's back and shoving him closer, pushing his face into the incredible bulge between his legs, smearing his face with the sweat pooling beneath his suit. "Yeahhh, how's that feel, little guy? How's my muscle-sweat smell?" he grunted, getting into his status as a growing beastman. It was impressive and divine in its shape. Dr. Grow could only imagine it unsheathed from its restraints but settled to see the outfit pushed to its limits. His hands attempted to lift the meat from its underside but his strength could not compare to its weight. Eagerly, Dr. Grow hoisted himself on top, feebly trying to climb on top of the manhood, pushing his weight against the thick bulge. He could feel his feet shifting as they slid the skin underneath the fabric. The hero's bulge was so big that it was enough of a platform for the smaller man to stand on top of as he balanced against the hulk's body. Bob chortled at how into this the doctor was getting, reaching down with his monster arms and pulling the little fella in to his abs, burying his face in the stretched-out bit of the suit that crossed the divide between his pecs. The doctor was in complete rapture. Half of his very being was scorched in the heaty embrace of his captive. His face could very well sink in between the crevice of the behemoth's chest. He craned his head upwards to catch a glimpse of the ripened man, lost in the handsome smug smile he had with masked eyes half way closed. It was hard to focus on such an amazing jaw line when the hero's breast continued to obscure it from sight. Dr. Grow widened his embrace until his hands glided far enough to caress the beefy nipples wrapped in red. It took the entire span of his arms to finally reach such a prize but that only excited him to realize just how immense the man had become. Bob groaned and instinctively bucked his hips gently at the touch of his fat, swollen nipples. His eyes pinched closed and he moaned softly, his smug grin getting even wider. "Nggghhfff...yeah...squeeze those super-nips, doc. See if you can even dent 'em!" he chortled, flexing his pecs against the doctor's frame. Just as Bob claimed, they were as tough and thick as the rest of him, it was like trying to squeeze a fleshy can of soda that was filled with lead! Much to Bob's ego, the grip of the doctor proved just how weak he really was, showcasing the comparison of just how mighty he's become. One flex of Incredible's chest swallowed up half of Dr. Grow's face, snaring him in walls of clothed, sweaty flesh that dumped the intoxicating alpha stench into the doctor's olfactory senses. Truly he has created something divine and despite Bob being so easily capable of snuffing the villain out, the doctor was rewarded instead with peak masculinity. The hulking hero groaned with bliss as he felt his chest muscles so easily engulf the normal-sized man, a hungry grin crossing his face as he pondered what to do next. His fingers were too thick to use that device that the doctor had, so he needed the little guy to cooperate with him. His man-stink seemed to be intoxicating to the little man...he wanted to grow more, so he needed the doctor to slip further and further into unthinking bliss. To that end he relaxed his chest and hoisted the doctor upward, leaning forward to press his lips to the much smaller man's own, growling as his tongue hungrily invaded the little man's mouth, stamping his masculinity and superiority into his face forever. So much force had entered into Grow's mouth. His hero was eager for more and communicated his hunger in a way that awarded the doctor further. With his face meeting with Mr. Incredible's, Dr. Grow had to lay belly-first across Bob's vast chest just to be drunk from. His noodly arms wrapped around the bullish neck, thrilled to be experiencing such a lust not only from himself but from his experiment, his guinea pig. He could make him as big as he wanted to and still he would beg for more. Happily, the doctor aimed his gun behind the giant's head and dosed him yet again as they continued to kiss. He felt the fabric beneath him stretching and creaking as it turned a lighter shade, the suit growing tighter and tighter across the hulking giant's frame. But if it bothered him in any way, he didn't show it, groaning in bliss as he began to expand outward once more. His voice grew deeper, his bones creaked as he grew taller, and the tongue filling the doctor's mouth expanded slightly. His head was growing but nowhere near the pace the rest of him was, his proportions were becoming freakier and freakier with each subsequent dose! Another ton and a half of muscle was added to his godlike body, swelling up past 14 feet in height. His man-stink rose into the air like heatwaves off of asphalt, filling the doctor's lungs with every breath he took. Dr. Grow had to part mouths, coughing as the intensity of Bob's hot breath was almost too much. As the ray stopped, he noticed just how much his position had been rearranged, his flat body balancing 90 degrees against hulking pecs instead of the previous slope. Knowing this, the doctor was all too eager to see what had become of Mr. Incredible. The middle-aged, balding hero chortled deeply when he looked down at the little man laying on his chest, reaching up to grab his lab coat with two fingers and hoist him up, leaning forward and placing him on the ground at his feet, allowing him to look up in wonder at the demigod he'd created. He couldn't see anything below Bob's eyes thanks to the huge shelf of his pecs, and the superhero was all too eager to make his head vanish completely with a simple flex of his titanic pecs, his body so wide that there was no way Grow could reach both of his nipples at once now. "Hahaha...Whaddya think, doc? Am I big enough yet?" he gloated, raising his arms to flex his biceps, the deep armpits soaked with sweat. "Nnghhh...pits feel all bunched up...must be a lot more hair in there than there used to be..." The doctor was dumbfounded. the sheer width of the titan was inhuman to say the least and the suit he wore, still clinging for dear life, hid almost nothing. Every freckle and hair follicle could be seen with only a hint of red shrouding it faintly. Dr. Grow had to keep stepping back just to keep the godly man in full view. "Amazing. You must show me more." Bob grunted, lowering his arms and pawing at his crotch, which had also grown disproportionately huge compared to his height. The gigantic shank of flesh in his suit had to be at least five feet long, and looked to be completely soft as well, his balls each the size of his bicep! "More..." he groaned, his eyes half-lidded, flexing his bicep against his pecs to rub and squeeze his nipples, his suit growing more and more soaked with his scent. "Believe me. I want more too, but I want to experience you my way. I've only seen you from the front but what are you hiding from the behind?" "Hehehe...there's more than you can see, doc. Check this out." His body sloooowly turned in place, each footfall shaking the warehouse around the two of them, making the ground beneath Grow's feet shake and rumble. He gradually turned his monolithic backside to the curious doctor, raising his arms and making his lats flare out as wide as they could go. "HRRRNNGHHH...YEAH...Check out this power, doc!" he roared, his back surging to more than ten feet in width! "My my, how much you've grown. I guess every part of you is perfect... well almost." Dr. Grow drank in the view, his eyes treated to a helping of Bob's beef. With his massive legs spread wide, the doctor couldn't help but keep his focus on Bob's low swinging balls, dangerously close to riding against the floor. Even more impressively was the ass. Luscious and fat yet still powerful and rippling, the two glutes were in a constant state of squeezing the life out of the black spandex that were strung between the boulders, each one having grown higher over the waist that even Mr. Incredible's lower lumbar was nearly unviewable by the enclosure of lats and cheeks. "Oh my..." Bob snickered, wiggling his ass in the air for the doctor's enjoyment, flexing the two gigantic, mountainous glutes together. "Grrhhhh. I could crush coal into diamond between these, haha! Anything you want flattened?" he asked with a cocky tone, squatting down to let his titanic nuts rest on the ground. "Nghhff...feel so heavy hanging from my crotch like that..." "Your ass is something to behold my guinea pig." Dr. Grow started to walk back towards Bob, as to gain a better view of his rump. The heat intensified with each of his steps. No doubt the entire warehouse was a sauna of stench, windows clearly retaining droplets of moisture in the air. "In fact, there's one last thing you can do for me and after this, I'll give you the fix you so deservingly need." Bob chortled, lowering his arms and attempting to look over his shoulder at the doctor, but his traps were too damn huge to make it possible! "Heh. I dunno if you can give me what I need at this point, doc. But I'll humor ya. What's that little thing ya need?" "Lay yourself down so I can experience that luscious rump of yours. After that, I'll make sure that damn suit comes off of you, and then some." The hero grunted, squatting down further, letting his knees impact the ground with a massive earth-shaking FOOM that rattled some of the sweat off the windows. His suit was fitting him like a second skin at this point, nearly transparent from being stretched so much, his body coated in sweat and man-fur that he hadn't had before. He laid down on his front, laughing as his pecs propped him up so much that he was forced to rotate his torso to the side, hiking his ass into the air to let the doctor explore it. "Heh. Try not to get lost in there, little man." So much mass had shifted with such a change in posture. With Bob having no space below him, his titanic nuts pressed out between his legs, right before reaching the prized booty. The doctor could see it now. The older man's crack had been loaded with blonde salt and pepperish hairs, barely concealed from the red suit. It was almost time to be rid of that obstruction but first, Grow climbed on top of Bob's ballls and graciously mashed his hands against the hulking glutes. He could feel the hair trapped beneath the suit crackling and grinding up against itself as he manhandled Bob's glutes, the man-stink just as strong here as it was everywhere else, a mohawk of fur ready to burst out from between his glutes the moment the suit was torn from his body. The hero flexed one glute, then the other, like a wave filled with steel. "Hahaha, you know, guys my age usually get a prostate exam, you up for the task, doc?" he teased, reaching back to grip his glutes tightly, pulling them apart as much as he could, exposing more hair and even more man-smell. "I'll give you something better." With a new air of dominance, Grow lowered his head into the enclosure, hoping almost to please Mr. Incredible as much as he was pleasing himself. He felt in control yet a part of him still enjoyed the idea of being Bob's bitch in the end. Deeper he went. Grow was slack jawed and ready to feast from his god. His tongue readily lapped against Bob's pulse. Even through the suit he could taste Bob's incredible manly essence, coating his tongue like an oil and overwhelming his senses, making him feel warm and hard as a rock atop the weathered hero. "Grrhh...that you eatin' my ass, doc? Hard to tell with how tiny and weak you are," he grunted matter-of-factly. Bob's words fell on deaf ears. Grow can tell he was speaking with command as his powerful words almost vibrated across his body. Nevertheless, the doctor kept swiping his tongue, drinking in the moment he would never experience again. With a grunt, Bob let go of his ass cheeks, letting them gently enfold the doctor between them, feeling his mass and power and warmth and sweat and stench surround him, temporarily trapping him in this musky jungle of flesh and fuzz, surrounded on all sides by glute muscle! What Bob hadn't expected was that familiar rush of growing energy coming from his ass of all places. As euphoric as having every inch of his body caressed by man-flesh, the doctor grew Bob further, letting the walls part away as to let him breath for air. Slipping out, the doctor fell out past the testicles and onto the floor, gasping and smiling as his arm was still extended, dosing Mr. Incredible more, sealing their deal. The hulking superhero groaned with delight as he felt his body swelling upward and outward, he was growing wider faster than he was growing taller! But he didn't mind, his rock-hard member throbbing as it reached up to his chin, the middle-aged hulk laughing as he raised his arms and tore the roof of the warehouse in half with a single motion, bending the metallic roof like it was made of aluminum foil. He took a big breath of the fresh air outside, now more than 50 feet tall, laughing with a steadily-deepening voice. "Haha! Yeah, that feels AWESOME, doc! Keep going! I'm gettin' so damn BIG and it feels better the bigger I get!" It was finally happening. The paper thin fabric that squeezed against the ever expanding musculature of the hunky hero was finally tearing. Rip by rip, the red uniform was giving up its endeavor to keep Bob remotely covered. The first to go were the black tights, their defeat obvious by the god cock that Bob had, nearing a size to his own body. Dr. Grow could only gawk at how much mass the titan was gaining, though the ray gun was proving to be less potent as Bob's dense muscles needed more and more energy to grow on. His sudden burst of size slowed down a bit as the tiny man below held his arm out to keep it going. He giggled to himself, smiling and licking the salty sweat that poured down on him as he was under his creation. "You hot monster..." left his lips whisperly, but unbeknownst to the villain, Mr. Incredible just so happened to hear him. All of the superhero's senses and powers were seemingly amplified by the ray's energy, not just his size and strength! He laughed as he turned to face the doctor, casting a shadow over him thanks to his massive pecs, his gigantic nipples pointed straight down due to the heft of his chest, leaking big drops of sweat as the hot sun warmed him up even further, the thick tangles of chest and armpit fur giving up big splatters of his sweat. "Grrr, that's right, doc! A hot monster that you created! I feel UNSTOPPABLE now!!" he roared, flexing a massive bicep, making the rest of his suit tear off, the peak of his muscle so tall he could press his palm flat against it! Dr. Grow stood up in shock, amazed to see the giant so high up hear him so vividly. As his finger left the trigger, stopping the growth temporarily, a large thin shedding of super suit had landed on the doctor's head, the smell so intoxicating and addictive, he was almost hesitant on even taking it off. His super beast was fully nude, drenched and clearly horny now, his mammoth chest inhaling and exhaling as though he had just finished a brutal work out. Citizens outside could be heard panicking at the sudden emergence of a 100 ton man attempting to look down at his tiny acolyte. Out of all the chaos ensuing, Grow could only say one thing: "Wait...you can hear me?" "Yeah!" Bob said with a grin. "Why, should I not be able to? I can hear all kinds of stuff, doc. Every part of me feels stronger. "Why'd you stop with the gun? Don't you want me even BIGGER, a more POWERFUL monster-freak for you?" he asked with a cocky expression, bouncing his massive pecs, sandwiching his freakish cock between them and starting to pec-fuck himself. Supposedly the ray gun had given the monstrous man some newfound power, another unforeseeable mistake thanks to Dr. Grow's incompetence at villainy. "Well... you'd want that wouldn't you?", he said, choking on his own words, although deep down he too wanted his experiment to take on magnitudes of size. "Besides, why the hurry? Why not show me just how much you love your new size. The city has so much to offer."

This part I am sure is one of the bigger parts of the Original RP people wanted... I hope I did this justice... There is a very ORIGINAL way I did the theft in this part, which was what I think people enjoyed the most. Also there's a bit of an easter egg to a few other theft stories. Enough chatter, I hope you enjoy this part. Previous Parts: -Part 01 - Part 02 - Part 03 - Part 04 - Part 05 - Part 06 Risk Takers Matt wraps his large arms around Andrew in a tight embrace. “You won’t lose me, bro. I’ll always be your big lunk of a gym rat brother.” He notices the warmth of Andrew’s body up against him; his size much bigger and solid than what he’s been used to before. Even though Andrew is still quite a bit smaller than him, Matt can feel the difference of his smaller twin’s body size. It felt so good actually he began go become a bit more attracted to Andrew’s new size. “You know…” Matt pauses a second, swallowing the lump in his throat. “If we used rubbers, the cum wouldn’t touch…” Matt takes a deep breath, proud of the thought but also nervous on Andrew’s overall reaction. “We know that it’s the cum itself that is making these changes – the cups proved that. So all we have to do is use some condoms, and we can fuck all we want without having to worry.” Matt chuckles nervously, squeezing Andrew a bit more firmly, pulling him in tighter into his body. Andrew looks up at Matt, a bit of a happier tone spread across his face at this new revelation that his twin has proposed to him. “That actually sounds like a great idea!” Before Andrew could even finish his sentence, Matt had his brother scooped up and in his arms. The effort he put into it was a bit of a struggle at their new sizes, but Matt made sure to get in a comfortable position for himself to carry Andrew; up the stairs to their room, where Matt gently places Andrew onto his bed. Matt runs his hands over Andrew’s body, taking note of the new muscle that has formed under his brother’s skin. “Gotta admit, Andrew, watching you grow like that was pretty fucking hot.” Matt smirked down at Andrew, groping his hardening bulge in his shorts, before pulling them down his thighs as they dropped to the floor which he kicks off of his feet and pushes them aside. Matt crawls on the bed between Andrew, his eight rock hard inches at full attention. Reaching out, gently gripping Andrew’s thighs, rubbing them up and down before slowly pushing them apart. Matt reaches over Andrew to his nightstand, pulling the drawer open and grabbing one of the many condoms inside. Smirking down at Andrew seductively, he puts the condom package to his lips, ripping it open with his teeth as he pops the latex sheath out of its wrapper and slides it over his hard dick. He takes note that it’s not quite as tight as he remembered it used to fit him. Matt shook off the unwanted feeling of his smaller self as he grabbed a tube of lube from the drawer, applying a generous amount to slick up his rubber-clad cock. Matt begins to tease Andrew’s hole, prodding it with his finger, applying a bit of lube to make sure he was ready to take him fully. “I’m gonna give you a good fucking, bro. Show you I’ve still got it, even if I’m a bit smaller than before. Andrew moans loud in pleasure as Matt’s finger probes his hole, opening him up for the incoming invasion. “Please be gentle… I haven’t done it before, bro.” Andrew’s hole was tight, and spasming; his ass clamping down tightly on Matt’s lubed finger. “I’ve wanted this for a long time though, bro. I’ve wanted you to Want Me, like this…” Matt feels a bit uneasy at those words, a chill running down his spine. He leans down slowly, kissing Andrew, removing his finger from his tight hole. His lubed up cock, covered by the rubber, is achingly hard. Matt leans forward into Andrew, making sure to press the head of his mushroom tip against his brother’s hole. The tightness of Andrew and the feeling of being opened up by Matt causes them both to moan in unison. With a soft moan, Matt slowly pushes his cockhead into Andrew’s very tight hole. He watches Andrew wince a bit in pain and grunts; Matt leans in to comfort him, pushing his lips onto his twin’s in a deep kiss. His mouth engulfing Andrew’s, tongue forcing its way between his lips and teeth. Matt growls into the kiss, pushing his cock in half way before feeling Andrew tense up more under him, his bro’s hole clamping down on the four inches inside him. Matt pauses for a moment, giving Andrew a chance to adjust to his size; even at eight inches, he’s still quite the hung stud. As he keeps his dick half inside he moves his mouth down Andrew’s face, to his jaw, then his neck, nuzzling against his brother’s ear before teasing it with his tongue. Andrew moans as his body is relieved of some tension, his hole relaxing a bit more, as he gives permission for Matt to proceed further. His hole opening up, Matt pushes in further, loving the groans and moans that escape Andrew’s lips. “Oh yeah,” Matt moans, feeling his thin pubes press against Andrew’s round muscle ass cheeks as he finally reaches the end, his cock fully pressed into his bro. “Fuck you got a nice ass, Andrew.” His breathing more labored as their bodies are pressed firmly together. Matt lifts Andrew up off the bed, letting his slightly smaller twin wrap his legs around his waist; Matt’s cock moving and shifting inside of him as they changed sexual positions. Matt moves over to his desk, sitting down on it. He places his hands on Andrew’s ass as he begins to lift his brother up and down on his cock in a steady rhythm. Andrew moans more and more with each thrust up and down Matt’s shaft in pure pleasure. Every time he is dropped to the base of Matt’s cock he gasps as he feels the large phallus leaving him as he is lifted back up the shaft towards the large head, just to start his long moan as he is lowered again. Andrew’s cock is rock hard and slapping firmly against Matt’s abs as Matt holds him close to his chest. Something then snaps in his own mind right then, the consequences if Andrew was to cum now without something blocking his spunk would be very bad. “Matt… Fuck… nnn… This….Is…A… Bad… Position…” Andrew manages to get out as Matt pounds into him, steadily speeding up his rhythm as he begins to go faster… and faster… “Mmm, Fuck no, Bro! This position is fucking amazing!” Matt growl’s holding Andrew steady as he slams his dick up inside of Andrew, roughly fucking his twin, loving the way Andrew’s lust is evident from his panting and grimacing facial expressions; the way Andrew’s cock hits his abs over and over as he fucks him hard, yet passionately. Matt’s own ass begins to rise up off the chair slightly as he tries to drive his cock in even deeper if it could even be possible; spreading his strong muscular legs wider, leaning back against the desk, driving his dick up into Andrew as he holds his bro in position. His balls begin to ache, he wants to fill Andrew up so much with his love, but they seem to tremble and swell as they begin to cause him pain. Matt snarl’s angrily, desperately wanting to cum as he begins to fuck Andrew even harder, roughly thrusting up into his twin, muscles tensing and flexing with extra effort as beads of sweat begin to form on his skin. Andrew continues to be tossed around, enjoying the pounding as he notices Matt’s face begin to turn red, as he finally cries out in agony, desperate for relief. “Ah, Fuck… Please Matt…” he moans into the rhythm. With a loud cry of pain and pleasure, but pure ecstasy, Matt explodes. “AH FUCK!!!!” Pushing deep inside, Matt feels his dick spasm wildly, the big rod rocking about wildly as his seed continues to erupt from his shaft, filling the condom. The reservoir tip beginning to fill… more… and more… There is so much cum rocketing forth, Matt feels like his cock won’t stop, but he realizes it’s not his choice, it’s something more. Matt’s Symbiote controlled balls are working in overdrive, filling the tip of the condom, making it swell larger and larger inside of Andrew as it continues to fill with Matt’s splooge. “Oh fuck, Matt…” Andrew’s eyes go wide as the rubber reservoir tip expands so much it ruptures inside of him, flooding the enhanced cock cream throughout Andrew completely. As soon as it breaks and flows into him, it’s immediately absorbed, but this time Andrew isn’t warmth spreading over his body; heat begins to fill him, a fire. Every muscle in Andrew’s body begins to tense up all at once, flexing hard against an unseen resistance. “FUCK! THIS…IS… HUGE!” Andrew’s height shoots upwards, almost instantly he is four inches taller, his shoulders broadening wider to provide new space for the muscle that is pumping out from under his skin. Every fiber of his being tensing as he gets bigger everywhere, the veins making a road map to every part of him as they pump with blood and begin to be seen without even a flex. Fifty pounds of solid mass was just added to him in mere minutes, and the show was just starting. Andrew’s own cock, six and a half inches of rock hard meat expands upwards and outwards, throbbing madly as it added one more inch of length and bloated thicker to accommodate his new size. As Andrew’s growth begins to subside, his body bordering on close to Matt’s size now, their bodies even closer than ever, his cock begins rubbing against the ridges of Matt’s abs. As it grew longer and thicker, his body becoming closer to perfection like his larger twin, he begins to gaze at himself in awe from these new changes, the pressure in his own balls begins to come to a head and spill out. As Andrew tries to move up off of Matt’s cock, his body has it’s own desires as his now perfect muscular bubble butt ass latches down on Matt’s cock, “FUCK!!!!” Andrew’s cock explodes! The load firing up into the air as it lands across Matt’s face, chin, and chest. There is nothing else he can do now, but to wait. Andrew wraps his larger arms around Matt, as his cock fires again, his brain going into protective mode, as all he wants to do is hold onto Matt, not realizing his cock is still firing off between their bodies as Matt begins to shrink a bit more. “No…. no no no no no!” Andrew holds Matt tightly as he sits on his cock still balls deep. Their eyes meeting for the first time since they were kids. Matt looks straight across, eye level to Andrew. But it seems a bit off, his eyes may be even a bit lower, but that’s not really surprising since Andrew is still impaled on his dick. Before he came, Andrew had to tilt his head down to look at him, this new status change had him slightly tilting his head up. “Damn Andrew,” he croaked, words a bit slurred. Matt reached up and tries to pull Andrew off of his tool, but Andrew is now too big, too heavy. 200lbs of pure beef sitting on his lap. Matt’s ass touches down on the chair, his trembling legs no longer able to hold up his brother’s weight as easily as he was able to before. “Fuck… you look good…” Matt finally takes in the full size and weight of his twin. His larger muscles, his masculine rock hard hairy chest, his powerful shoulders, and his vasularly huge arms. Andrew lifts his ass up off of Matt’s cock, pulling the obliterated latex condom out of his hole. “Look at me, Matt.” He walks over to Matt’s large mirror that he had installed to check his own perfected body out in. Andrew lifts his right arm up, flexing, watching the ball form of his bicep. He brings his other arm up and shows off a most muscular for Matt. Seeing the tightness of his six pack and much larger pecs. Andrew in a matter of minutes has went from a jock built to something more like an amateur athlete. Andrew moves his hand down his furry chest, crossing his hairy covered abs till it meets his cock, which now looks much more adequate with his thick pubic bush. He gives it a squeeze, as he notices Matt looking at him through the mirror. Andrew spins around to face his twin. “No more, Matt…” Matt shivers with desire as he watches Andrew flex and pose and feel up his bigger body. He slowly stands up, walking up to his twin. He’s still taller, but only barely. One inch at most. He also has a slight bit of muscle still on his once tiny bro, but maybe only about twenty pounds if that. Matt brings his own arms up and flexes, his biceps rising up proudly under his skin – he’d still be impressive to anyone who hadn’t seen him flex a few days earlier. His arms are clearly still a bit bigger then Andrews. Their cocks, on the other hand, look exactly the same size. While Andrew’s dick is more obscured by his new full bush, it’s clear that the two were hanging equally low. “Damn, Andrew. You look good.” Matt purred as he looked his twin up and down. “I’m almost glad that was a defective rubber. Andrew smirks at his bro, crossing his larger muscular arms in front of his newly firm pecs. “Control yourself bro,” his voice has lowered more drastically with this new change. “Another mishap and I’ll probably be the same size as you.” He stretches his arms over his head, feeling his new size. “Well, we wasted our day with experimenting. All this growth sure is making me tired.” Andrew lets out a deep yawn as he goes to sit on his bed. Matt’s eyes never leaving his body. Matt walks over and joins Andrew on his bed, reaching out, massaging Andrew’s newly thick shoulders and traps. “Having a twin who’s the same size as me wouldn’t be the worst thing,” he tried joking as he rubbed Andrew’s thick neck. “Who knows, Bro? Maybe you’ll become a gym rat like me!” Matt laughs, as he throws his head against the pillow on Andrew’s bed. Matt pulls Andrew back into him, until they are both prone and laying in each other’s arms. “Remember how we used to do this, as kids? Sneak into each other’s beds, just stay awake for hours at night, talking to each other? Well, whispering back then. We didn’t want our parents to hear us awake.” He chuckled. “Those were good times, weren’t they?” Andrew lays against Matt’s arm; its smaller then he’s used to with his new size and the lack of size Matt once had as he reminisces about those great times they shared. He grins, turning to face Matt. “Yeah…” Andrew leans in and tries to get a whiff of Matt’s underarm, but when his nose nuzzles Matt’s inner arm, there is no longer that manly masculine scent that he loved so much. He sighs, “Don’t you miss being big, Matt?” “A little. Okay, more than a little. I do miss it. It’s weird, you know? One day I’m the big man on campus and the next, well, not so much.” Matt pauses for a few seconds, gathering his thoughts. “But it’s not all bad, you know? I’m, uh, learning to look at things differently. A Different perspective or whatever. Maybe I wouldn’t have chosen this, if you’d asked me a couple days ago. But hey, lemonade out of lemons right?” Matt turns his own body to look Andrew right in the eyes. “And you’re finally getting some meat on you! For me, that’s definitely a big plus!” Matt grins back at Andrew, running a hand over his brother’s hairy chest, feeling the contours of the new slab of Andrew’s pecs. “Could be worse, right?” Andrew pushes himself up on his elbows. “You’re right. It could have been worse. What if we were complete strangers, or even some stupid roommates?” Andrew bursts out laughing. “At least it’s happening between us, two close brothers.” Andrew moves in to kiss Matt, this time much deeper as the wall between them begins to break, most likely due to the recent surge of Andrew’s confidence from the recent growth. “If I get bigger then you, Matt, I will be there for you like you have always been for me all these years.” “Mmm..” Matt murmurs, surprised and pleased by the force of Andrew’s affections. “I know you’ll be there, Andrew. I know you’ll look out for me. I want you… too…” Matt’s voice catches as the words “Want You” escape past his lips. Like something deeper inside him is triggered. Matt can’t quite figure it out, but it makes him feel safe pressed against Andrew; their hard bodies mashed together on Andrew’s bed. His dick slowly starts to stir again, but Matt wills himself to behave. After all that’s gone on so far, he’s not entirely sure he can take much more, even though a deep part of him desperately wants it. Andrew yawns again, exasperated from the events of the day. “Well… I’m just gonna… sleep…” Andrew crashes out on the spot, his head hitting the pillow as he begins a deep snore. His body needing to recharge from today’s dramatic growth ordeal. As Matt pushes himself off the bed to move over towards his own, Andrew begins to mumble words in his sleep… To Be Continued... Coming Soon Part 07: While You Were Sleeping

Previous Parts can be found here: - Part 01 - Part 02 - Part 03 - Now here is the long awaited Part 04... Part 04 Want Me, Want You Matt pulled Andrew’s warm body into his larger frame. He felt the need to be protective over his much smaller twin. He stared at the TV blankly, not really interested in what was playing on the screen, but more interested in what happened at the gym. After his workout. That shower encounter with Dan. It was frightening and the thought of Dan getting his large paws on him after he grew to epic proportions was making Matt even more fearful. Matt looked down at Andrew, noticing the new muscles on his smaller twin brother. Even thin, the muscles definitely stuck out with great curves and definition for his smaller size. The muscle on Andrew though, just thinking about it gave Matt a feeling of comfort. He slowly closed his eyes and drifted slowly to sleep. *** Dan and Andrew appear before Matt as he stared up at them from his spot on the couch. Both his brother and rival stood in front of him, but Andrew looks much different. He is massive, built like a tank. Both of them with huge giant cocks that were fully hard and being stroked over him. They are so large they literally cast a shadow over the tiny Matt. Matt tries to stand up. He’s fearful of what is about to come, but his legs won’t move. With a smirk on their faces, both large men reach down for Matt and grab him around the throat… *** Matt suddenly jerks awake from the nightmare that was about to unfold. He looks around the room for a moment before looking down and seeing his smaller twin still sleeping by his side. He also notices his own cock is once again tenting visibly in his shorts. Things begin to click in his head; something very strange is going on. If it wasn’t for his cock being a huge distraction, he might even be able to figure out what it might be. Andrew begins to stir awake, stretching his arms out, noticing the hard cock pressing out underneath the fabric of his brothers shorts. They were stretched out into a very large tent. “Hey there, big guy,” Andrew looked up at his brother, sleep still in his eyes. Andrew’s own cock was hard as well, its 5 inches pushing against his tight bathing suit trunks. “You look worried still. Something is not right with you.” Andrew reaches out to touch the highest point of Matt’s tented shorts where a big spot of pre-cum was beginning to form. He moves his hands across the top, making Matt moan a bit before moving his fingers into his mouth to taste his larger bro. Andrew noticed there was nothing to taste, Matt noticed the spot was completely dry where his brother was just touching. Matt looks over his brother. His mouth opening in shock and awe as the blonde hairs on Andrew’s arms and legs began to darken, more and more, until they took on a black color like the hair on his head. Andrew grunts a bit, clutching his stomach for a second. When he moves his hand Matt sees another change, the deep cuts of his 4-pack have now taken on a much more cut look. Four true bricks popped prominently out of his smaller brother’s skin and he wasn’t even flexing them. “You can tell me anything, Matt,” Andrew gazed back up at his brother. “We’re twins. You protected me when you kept on growing. Can’t I protect you, Matt?” “I just had a weird dream, that’s all.” Matt looked down at Andrew bashfully, not sure if he really should say just how weird it was. He felt a bit awkward after Andrew pressed his finger against the wet spot on his shorts, taking his pre into his mouth and watching it completely disappear. Matt noticed his smaller bros own tenting swimwear. Reaching over and grabbing the waistband, he slowly pushes Andrews’s shorts down slightly, just enough for his five inches to bounce free and straight up. “Right now, it looks like you’re the one who could use some help, Andrew.” Matt reaches down and rubs his brothers balls gently, the small orbs rolling around in his finger as he watches Andrew’s cock rise a bit higher as his arousal increases. He slowly moves his and up the shaft, pinching the cockhead, causing a bit of clear pre to seep out of it. Matt brushes the pre off with a fingertip, bringing it to his own lips, before pushing his finger into his mouth. Andrew looks up at Matt. Seeing the finger go into his brother’s mouth was a turn on, but something else was happening. As he continued to watch, Matt’s beard was beginning to get thinner. The hair on his arms and legs began to get a bit less dark. Andrew watched and began to get a bit excited at the sight of this. He reached out to Matt’s shorts, pulling them down, watching his brother’s huge cock finally emerge, free and hard. He was being drawn to the bubbling hot cum emerging from his larger brother’s piss slit and could practically taste the sweet pre-nectar. Matt continued to stroke Andrew, and although Andrew was so fascinated with Matt’s impressive display, the attention Matt was giving him still brought his attention back to himself as he let out a moan of pleasure. Andrew reached forward as his brother continued stroking, touching Matt’s cock juice and scooping up a good amount, bringing it to his lips, tasting it. As soon as it touched, hair began to push out of the pores of Andrew’s underarms; large tufts of hair erupting out of his pits, thickening more and more. Going south down his body, a trail began to grow out of his pubic bush, going straight out of his waist line and attaching itself to his belly button as the start of a treasure trail formed on his body. Andrew lifts himself up a bit, pressing his lips to his brothers as he kissed him as best as his smaller body could with a strong hand still gripping and stroking his cock tightly. “I fucking love you, Matt.” Andrew rubs the side of his cheek against Matt’s bull neck, a slight bit of course skin from him makes Matt shudder and excited as he realizes Andrew has the beginning of stubble forming on his face. Matt growls, pulling Andrew against his body with one hand, using his free hand to continue to grip Andrew’s hard dick. “I love you too, Andrew.” Matt takes one long breath, letting out a low groan of pleasure as Andrew’s stubble continues to rub against his thick neck, driving him even wilder. Matt’s dick surges in Andrew’s hand, rock hard and throbbing; yet it’s not as big as it was before. Although it could be that Andrew has a bit of a better grip on his cock. Matt bends down a bit, bringing his lips down to his brother this time; they slowly kiss, letting the passion smolder hot and low. Matt begins to slowly make his larger hand rise and fall on his brothers cock, feeling Andrew quiver from the hand job he was giving him. Matt reaches over and grabs Andrew by the hips with both of his hands, pulling his smaller brother up onto his lap. Both of their dicks rubbing together; the pre cum from both of them mixing as they kissed. A weird sensation begins to fill both of them as they look on at each other, both of their bodies begin to show differences. Hair begins to rise out of Andrew’s skin more, traveling up his small set of abs and beginning to branch up to his chest. The hair begins to swirl across each pec muscle; its light, but he more contact he has with Matt, the darker and darker it begins to change as the precum continues to flow from each of their hard dripping cocks. For Matt, the changes are the opposite. It almost looks like he has begun to start shaving his fur to make his muscles look bigger. The hair begins to thin out and starts retreating in some places right back through his pores as if the hair was never there. As he continues to watch his chest hair disappear, he gives another glance at Andrew and notices wisps of hair beginning to sprout on his twins chin. Andrew feels the sensation too, scratching at his face, feeling more and more tiny hairs begin to sprout outward and get coarser. Andrew looks up at Matt, seeing his brother’s facial hair begin to slowly retract away as well. “We need to stop, Matt.” He tries to pull away, but Matt is almost entranced by his brother’s changes, holding onto Andrew even tighter. “Mmm… Fuck no, Andrew,” Matt growled, wrapping a huge arm around him, keeping his brother in place as he looks on at the new developing beard thickening on his smaller twin, growing denser and more noticeable with each passing second. Matt is getting more and more turned on watching Andrew becoming increasingly more manly and studly. “I want you so bad, Andrew.” Matt rolls both of them over so that Andrew is on the couch and he is right on top of him, his huge body pinning his twin in place, still much more massive then him. Matt leans down, kissing Andrew’s neck… his collarbone… his chest… and his abs, slowly sliding off down off the couch to kneel in front of his smaller brother. Matt rubs his jaw against Andrew’s thighs, and Andrew notices how Matt’s course beard and stubble are almost none existent; there is no rough and bristly sensation like there should be with a man that has had some kind of beard growth before, they are almost soft by comparison, Matt leans in and gives Andrew’s shaft a few experimental licks, then pulls down Andrew’s swim trunks down a bit further to get access to his balls. Matt licks at them a few times, kissing them, sucking on them, pressing against them with his tongue. Matt takes a quick look up at Andrew and breathes in his scent, sitting there with his legs spread, a new musk permeating from his brothers loins and races up into his nostrils. Matt’s eyes open wider with aroused delight. “Stop? Why would I stop? Are you telling me you don’t like it when I do this?” Matt kisses one of Andrew’s testicles, “or this?” he licks the other one, “or even this?” he runs his tongue up the sensitive underside of Andrew’s shaft, then kisses the cockhead, his tongue darting out to lap up a bit more of the pre-cum bubbling out of the tip. Andrew watches on as the last traces of beard retreat away from Matt’s face. All that remains is his sideburns. Andrew watches, more shocked than ever. The guy who was once the manliest looking man he had ever seen was almost now completely hairless from the nose down. Andrew reaches over and grabs Matt’s jock strap; it’s completely soaked with pre-cum. Or it was, as in a matter of seconds, it’s completely dry. “Oh, fuck!” Andrew looks down at Matt, as Matt gazes up at him. A new lust bleeding out of Matt for Andrew as Andrew’s masculine identity intensifies and it begins to almost pulse off him and pull Matt right back into him. Andrew’s cock begins to get harder than it has ever been. “Well, that answer’s that, doesn’t it?” Matt smirks, moving forward. He engulfs Andrew’s cockhead with his mouth, moving slowly down the hard shaft, until his face hits the new forest of pubes around the base of his brother’s cock. He continues to push forward, not stopping until the tip of his nose touches Andrew’s torso. He then begins to bob up and down on his dick, his huge muscles tensing under his shirt as he blows Andrew as if his life depended on it. Matt runs his hand along Andrew’s thighs, massaging them gently, noting that they seem just a bit sturdier than he last remembered. Andrew just sits back as Matt sucks on his hard shaft. He reaches a hand shakily toward his brother. Matt looks up and sees his arm moving, and he grabs it, placing Andrew’s hand onto the back of his head. Matt smirks a bit like ‘Fuck yeah, little bro! Take charge!’ Andrew swallows the lump in his throat, a bit more at ease as he watches Matt’s head move back and forth along his cock and his own hand rubbing along the top of his brother’s head with the motion, his fingers moving through Matt’s hair as he felt himself getting closer and closer to climax. “Matt… Nnnn…” Andrew begins to grunt a bit. “Fuck, it feels so good…” Andrew reaches his other hand out and places it also on the back of Matt’s head, assisting him a bit more with his blow job. As Matt begins to pull back, Andrew pulls him back towards his deep musky bush of pubes. Matt enjoys the feeling, Andrew pulling him downward onto his dick as he continues to push and thrust his hips up to meet Matt’s face, driving his dick right down his throat. Matt relaxes, letting Andrew guide him, move him, use him as a tool for his own pleasure. The whole time, he wants Andrew to do all of that, to fuck his face with his blossoming manly cock. Matt distantly realizing that’s a very submissive thing to think, and not at all like how he usually is. But right here, right now, at this moment, it seems like the most natural and perfect thing imaginable. So he maintains his suction on Andrew’s dick as best as he can, while letting his twin pull his head back and forth, forcing him down on his cock. Andrew moans deeply, feeling something inside of his ball sack, unlike anything he has ever felt before beginning to build up and radiate from within. He looks down at Matt, moving his hands away from his head for a second to let Matt get a glance at him. Matt still continues to suck though, waiting for his reward. “Matt…. Ahh Fuck… You want this right?” Andrew’s balls begin to churn and ache, but he can’t release just let; something inside is holding it back. “Please Mat…” They begin to pull up; he feels as if the cum is beginning to creep and pump into his shaft, ready to explode outward into his brother’s waiting throat… “Want… Me…” Matt breathes for just a second, just long enough to say, “Want you so bad, Andrew,” before plunging back down onto his brother’s dick, taking the whole five inches in one go, pressing his nose deep into his bush, into the flesh of Andrew’s torso. He can feel Andrew’s dick shaking, quivering, and trembling. He knows his twin is about to explode. Using his tongue, he teases the underside of the shaft, sucking stronger than ever, eager to pull Andrew’s cum right out of his shaft if he has to. Andrew’s hands go right back to the back of Matt’s head. He pushes himself forward, almost leaping off of the couch and knocking Matt over, but Matt makes sure to hold on tight as Andrew presses his pubic bone as far as he could up against Matt’s face. His cock lurching round Matt’s lips, in his mouth, down his throat as he fires the first salvo down into his brother’s waiting belly. Matt has no time to swallow as a second blast fires into his mouth, coating his tongue, followed by a third, a forth… Matt loses count, not knowing when it will stop as he continues to try to swallow it all. In the meantime Matt’s body is undergoing another de-metamorphosis. His muscles begin to shrink in size at a steady rate. Andrew’s cock becoming a bit harder to suck as his body shifts on the floor, losing another inch in height, and then another. Matt begins to see what’s going on, and pushes Andrew off of him. His body shifting more and more laying on the carpet, yet he’s not even moving at all. Matt looks up at Andrew, finding his twin’s eyes. He’s just as scared as Andrew is now. Things are different, and will continue to be from now on. Matt feels weak, and right before he blacks out he hears the calming sounds of Andrew’s voice. “I’m so sorry Matt…” To Be Continued… Coming Soon Part 05: The Experiment

If any of this offends you, please refrain from reading the story. Thanks, and hope you enjoy. Written as part of a trade with someone from a different site. (first time posting a story on muscle growth btw, but have done some writing before) ----- Phil had gotten back to his home after yet another day of work. He got to his front door and noticed a small package included with his usual assortment of mail. He brought the stuff inside and, setting the mail down, looked more closely at the box. It had no label on it to indicate what it was. He was nervous for a moment. What if it was a prank thing or something worse? Curiosity got the better of him though, and grabbing his scissors, he cut open the package. He could instantly smell something of linen, as well as something else he couldn't quite place. Inside was a fairly large white shirt and (Phil blushed) a jockstrap fell out as well. He picked up the shirt first; one of those fitted polyester sports shirts athletes wore. It seemed just a size too large for him though, so he set it aside. He then tentatively picked up the jockstrap. Unlike the shirt, this article looked to be about his size. It looked clean, but he felt he could smell something curious on it. He slowly brought the jockstrap closer to his face before taking a big whiff of it, smelling the slight aroma of a strong musk. He blushed and pulled the jock away as he felt his cock harden a bit. He tried to think of what to do with the stuff. Clearly at least the jock had been used before, despite being clean looking, but Phil thought about how much he loved stuff like this. He looked at his skinny arms, always fantasizing about becoming a muscled beast of a man. He looked at the stuff resting on the table, especially the jockstrap. "Maybe I could just wear that... make me feel like a regular athlete." He paused a moment longer before he dropped his pants and boxers, sliding the jockstrap up between his legs. As it finally slid past his slender butt and lightly cupped his crotch, he went over to a mirror to check himself out. He looked at himself in his jockstrap and shirt, looking anything but muscular, especially with his very slight belly pushing out his shirt. Despite that, he couldn't deny how well the jockstrap fit against his body. He stared at himself a while longer, finally snapping out of it as he realized he was slowly getting a hard on. He shook his head and went to go put his clothing back on, not bothering to take off the jockstrap. The next couple hours seemed just fine. Phil went to his desk and got to work on some drawings-a favorite hobby of his. He was doing well, his craft honed from years of practice as he drew a character on the page. Even this needed a break though. He stood up and massaged his somewhat sore hand as he went over to the bathroom. As he pulled down the zipper, he was reminded of the jockstrap. He had almost forgotten it, the fabric was starting to feel so natural against his frame. He smiled and relieved himself, wanting to get back to work. When he sat back down though, he started feeling a bit uncomfortable. The room felt a bit warmer than usual, causing Phil to lightly sweat. He pulled off his shirt to cool down, his moderately hairy torso glistening a bit with sweat. He felt more comfortable though, and he leaned forward to continue his work. The jockstrap, starting to soak in a bit of his sweat, tingled lightly against his crotch. He ignored the light pulses of pleasure he was feeling as he picked up his pencil, and he immediately paused after grasping it. He looked at his hand confused. The pencil felt a bit awkward in his grasp, as if it had become a more slender style. It didn't seem any different in his grasp, but it felt off nonetheless. He continued trying to draw, having more difficulty due to the feeling. As he slumped over the desk, his sweat-glistened torso began to alter. His small stomach receded slightly as his chest swelled out lightly. Resting his arms on the desk as he worked, his flexed biceps puffed outwards as well, the muscles cramping for a moment before settling into their new size. He paused. His whole body had a slight tingling soreness to it he couldn't quite place. He passed it off as having sat too long, giving him a reason to respond to a new hunger he hadn't noticed before. His stomach gave a loud rumble as he pulled his shirt on over his head. For some reason it felt tighter than usual. He looked down and saw his pecs lightly pressed against the fabric where they would have been obscured before. His shirt sleeves bunched up on his arms a bit too as he flexed. Phil felt great concern for these new developments, but another rumble reminded him of more urgent cares. Phil rushed to the kitchen and wrenched the refrigerator door harder than he had intended, not knowing his new strength. He looked around inside, wondering what would be best. His eye caught a large, packaged steak, and his mouth watered as he pictured eating it rare. He shook his head. "Rare? I only eat medium well." Still though, the steak looked appetizing. He popped it on the stove to cook and tossed a few potatoes into the oven. As the meat sizzled, his patience grew thin; the aroma of the meat made him salivate and lick his lips. He waited only 7 minutes before pulling it from the stove, digging in almost immediately. The meat easily ripped apart in his mouth as his lower canines gained a little height and sharpness. The steak was medium rare, but no steak had ever tasted so good in his life. He resolved to eat them like that from then on. After 8 minutes of inhaling his food, he sat back in his chair, releasing a great belch. It took a few moments, but Phil realized how he had just acted, and felt a bit appalled he even ate his steak that rare. "I must be coming down with something. I've been feeling weird all evening..." Wanting to put whatever sickness he had to rest, Phil carried himself upstairs to get ready for bed, unchanging down to his new jock before plopping down onto his bed, entering a deep sleep. ----- The rays of sunlight eventually stirred the man as he slept. He yawned and stretched, feeling a bit sore all over. Phil let out a belch as well, and it was then that he realized something else was off this morning. Bleary-eyed, he pulled off the sheets and was immediately hit with a wave of strong musk. It felt like he hadn't showered in a week, and to his surprise, he grew a little hard at the thought. From what he could tell, his feet weren't faring too well themselves in the scent department. He shook his head to clear his thoughts, and reached for his glasses on the dresser. He blinked and took them off for a moment. It almost seemed like... he could see a little better without the glasses. A double check confirmed his theory. He gave an annoyed grunt, vowing to see his eye doctor soon enough for a better pair. With his slightly blurred vision, he didn't notice the changes his body went through in the night. His muscles had increased a bit more, and the hairs on his chest continued to thicken. He stumbled into the bathroom, pulling aside the pouch of the jock to let his cock free to unload his bladder. He aimed it with one hand, noting it felt oddly heavy. He guessed that his cock was just still subsiding from morning wood, not realizing it was indeed thicker than the day before. He slipped the tool back into the pouch of his jock and took a look in the mirror. His beard seemed a bit fuller or scragglier than usual. He rolled his eyes and grabbed his razor, trimming it up back to its normal chinstrap look. He took a quick look at the clock in his room and realized he would have to start moving quickly if he didn't want to be late for classes. "Crap!" He shouted before bolting out of the bathroom, any idea of a shower pushed out of his mind. In a rush, he grabbed a can of deodorant and sprayed his pits and crotch vigorously, hiding the musk under a thick layer of aromas. Tossing the can aside, he pulled open his dresser drawers to try and find something suitable to wear. A pair of jeans fit more snugly than usual, but he was still able to get them on without too much trouble. His shirts, on the other hand, did not fare as well. He could barely get any t-shirt to fit over the top of his head and larger shoulders, let alone allow him any sort of decent motion. In frustration he ripped them off, tearing a few with his new strength. Desperate for something to work, his eye looked at the package from yesterday. With no other options, he took the athletic shirt out and wrenched it on. Despite having seemed too large the previous day, it seemed to hug his body in all the right places now, accentuating his pecs, forming abs, and bulging arms. He rubbed a hand down the front, his fingers gliding over the smooth material felt good as he felt the slight contours of his torso. He thought he could feel abs too. He was confused and looked down. Sure enough, his stomach had receded enough to show light bumps when he flexed his stomach. "Guess I never realized how far I've come with the dieting..." he mumbled to himself, a bit scared but excited at the same time. It Made him feel manlier. Remembering he was on a time schedule, Phil grabbed a coat and his bag. He quickly shoveled some food into his stomach in the kitchen, grunting to himself about the lack of meat people have for breakfast, then ran out the door. His morning classes seemed alright, but Phil kept his jacket on to try and hide the odd body changes he had started experiencing. The information in the classes was going right over his head as his mind started drifting. Thoughts of working out and relaxing seemed so much better than boring books, and the occasional rumble of his stomach wasn't helping him concentrate either. He stretched in his seat to try and wake himself up a bit more, pausing when he felt resistance in his clothing. The shirt had fit comfortably only a few hours ago. He subtly unzipped part of his jacket and took a peek inside. His pecs were pushing harder against the fabric, nipples slightly hardened too. His shoulders were also bulging the sleeves. Phil quickly zipped the jacket back up and gulped. This shouldn't be happening. He had no idea what was wrong with his body. To make things worse, seeing his altering body had made him a bit horny. He adjusted his meat inside the jockstrap, trying to will it to go down, but the attention only made him want to play with it more. He gave it a couple of lewd gropes before realizing he was in public, blushing deep red. This only made things worse for the confused man. The combination of embarrassed heat and having the jacket on began to make him sweat, small beads running down his wider back and through the crevices on his chest and abs. His crotch started to sweat as well, the salty water mixing in his pubes and jockstrap causing a reaction. Unknown to him, his musk was starting to slowly overpower the deodorant he applied that morning. Around him, a few people were beginning to crinkle their noses in disgust while some others, confused and nervous, adjusted themselves. Phil eventually got a whiff of it as well and realized, judging from the looks being shot occasionally in his direction, that it was him. He coughed nervously and blushed a bit, waiting desperately for the clock to hit 12:30. With his embarrassment and stomach leading the way, Phil walked out of the classroom as quickly as he could. Phil was starting to panic a bit, and he vowed to sort it out as soon as possible. His stomach growled loudly. Maybe he'd wait till after lunch... Following his stomach, Phil walked to the cafeteria. He started moving towards the salad bar-a common choice ever since he started trying to diet- but after grabbing a couple different veggies he gave a grunt of dissatisfaction. His nostrils flared a bit as he smelled something delicious in the air. His mouth watered as he turned to the grill area, forgetting the plate he had been preparing. On a whim, he ordered 3 burgers and a large helping of fries. Quickly paying for the items, he rushed to sit down at one of the tables, wolfing down the first burger in seconds. It wasn't rare like he would have liked it, but meat was meat. He shrugged and started work on the second burger, taking a bit more time to savor the juicy meal. His body was immediately beginning to take to the nutrients he was receiving. The shirt feeling tighter than ever as his pecs pushed out more, abs looking more like thick cobble stones. His widening lats weren't doing any favors to the poor shirt either, stretching it taught. Even his pants were beginning to feel a bit tight as his glutes swelled like hard rocks and his legs followed suit. Tightest of all though were his shoes. His toes crammed against the ends as it felt like the material was crushing his feet. Halfway through the third burger, he gave a grunt of discomfort in a voice lower than he usually had. He unzipped his jacket and shimmied it off himself in an effort to feel some relief from the tightness. All he managed to accomplish was letting his musk out more freely, radiating a bit from his pits but especially from his crotch. He took in a deep breath, his nostrils staying flared this time, and felt himself harden a bit. He felt like such a man eating meat and smelling like a beast. He started rubbing his crotch through his pants again as he began working on the french fries. Absorbed in the image of his masculinity, coupled with the pleasure of his teasing, Phil didn't realize anything was wrong till a loud rip brought him back to reality. Looking down between his arms, he noticed a large rip down half the middle of his shirt, showing off the deep and hairier crevice between his well-formed pecs. It seemed so unreal. He reached a hand up to cup one of the slabs of muscle, giving a deep, masculine moan as he brushed one of his nips. The sounds had started to attract some attention from surrounding tables. People gave him looks of confusion while others whispered and laughed. Phil blushed a bit and tried to act natural, attempting to pull on his coat again. The motions of his larger muscles caused his athletic shirt to rip further, beginning to reveal the hairy hills of his abs. He thought all would be safe, but as he pulled the jacket over his shoulders, he accidentally ripped a hole in the back, forgetting his new strength. This all seemed to just attract even more attention, making the man even more embarrassed. To add insult to injury, his rising heat levels made his musk radiate more, the jock clinging to his crotch tightly with sweat. Standing up was even worse, as he realized his boner-a full 2 inches longer than normal- pressed tightly against the fabric of his pants. Adding to the attention surrounding him, his first couple of steps were marked with loud rips as large, hairy toes poked out the front of his shoes. At this point, there was little he could do to remain unnoticed, so he rushed out of the cafeteria, knocking a few people over in his haste. He shoved himself into his car, adjusting the seat back a few notches so he would fit more easily, and awkwardly pressed down on the gas with his growing feet. The laces were straining, the rips in the shoes growing bigger as the shirt continued to rip as well. He got into the driveway and bolted into the house, slamming the door behind him and breathing heavily. "This is wrong. So very, very wrong" Phil groaned to himself. With hesitant eyes, he looked down, seeing the moderate mounds of his pecs pushing against his coat. He tentatively unzipped it and carefully took it off, groaning again as he saw the tattered shirt and odd muscled and hairy body underneath. With a frustrated grunt, he ripped the shirt right off his body and tossed it to the ground. His muscled torso glistened with sweat, and it felt good to finally get some cooling relief. Large pecs with hard nipples, rows of hairy abs, a defined Adonis belt, and biceps the size of soft balls. It looked as good as it felt. Looking further down, he noticed the large outline of his cock draping down one of his pant legs. His eyes widened. Even at full erection, he was never as big as he saw now. He felt an impulse to fondle it, but held his hand in check as he took note of the other changes. His muscles hugged close to the jean fabric, making the friction on his crotch all the more intense, and the shoes were a complete mess. He bent down to loosen the tight laces in hope of getting them off his feet. His hands, a bit larger and meatier than he was used to, fumbled clumsily with the strings and he instead opted to rip off the shoes with force, his shoulders and arms flexing hard as he pulled apart the sad shoes. Wiggling his toes, it finally struck him how smelly he was. His feet, overly hairy on the tops and toes, had a sweaty smell to them, and his armpits weren't faring any better. He took another good whiff, his flared nostrils stretching out further. He gave a deep moan as his voice became fully baritone, his cock pressing even harder as if wanting release. Phil felt so strange, he had never been that into scent, especially his own, and the muscle that should have made him panic only brought more excitement. He stood there, conflicted for a minute, before his second head won the fight. Phil rushed to his bedroom and shimmied out of his tight pants, giving a huge sigh of relief as his cock was allowed to spring forth, partially hugged by the jockstrap. The remaining article of clothing was completely damp with sweat and hugged his balls tight. The musk radiating off of it smelled like a much stronger version of what Phil had remembered yesterday. Some inkling in his mind knew that the jockstrap and possibly sweat was causing him to change, but he didn't care at that moment. With a grunt, Phil grabbed his now 10" tool with one of his large, meaty hands and started stroking. The rippling feeling of his muscles as he stroked, the manly musk radiating off his body, Phil was in pure ecstasy. He lifted his free arm and shoved his nose into the pit, his open nostrils taking in the salty, manly musk. All the strange new feelings he had, added to his semi-hard on he had all day, caused him not to last too long. Body growing even hotter and drenching his bed in a bit of sweat, the man roared and shot his load, getting a bit on himself but a lot on the wall behind him. The intense experience left him drained, and Phil quickly nodded off to sleep only in his jockstrap. ------ Everything was quiet, apart from some of the snorting snores occasionally filling the space. Phil slowly awoke, eyes cracking as he peered around. It was still dark, some early hour of the morning. He glanced at the clock on his end table, seeing it read 4:00am. It didn't even register in his mind that he was seeing the numbers clearly without his glasses. What did register was the soreness he was feeling throughout his body. All of his muscles throbbed, as if he had the most intense workout of his life the days before. Coupled with that, the stench was as strong as ever. The cum that he splashed on his skin had been dried, and that coupled with the scent of his old sweat was pungent. The original jock strap smell was nothing compared to the animal he smelled like now. He reached an arm over to flip the light switch and was welcomed with a foreign sight. Two slabs of meaty pecs greeted him as he looked down. Underneath, a 6-pac with nearly an 8-pac visible. He reached to feel his chest, feeling the curve of the muscles and the crevice between them. In place of the cum that had sprayed his chest yesterday, a thick forest of hair was in its place. The same could be said for his even furrier abs, and his legs, though not in the firing range, had become hairy masses. His feet looked strangest of all, a full 4 or 5 sizes larger than the previous day. His toes were thick, the nails darker for some reason. Phil sat up slowly, leaning his back against the head board. He stretches, his muscles and joints popping. He had grown a couple inches overnight too, not that it was noticeable over his other changes currently. "What is wrong with me? It feels so good, but... it doesn't feel right." He held his head in his hands as he tried to think, and he jumped a bit as he brushed past his ears. He got out of bed and walked over to the full length mirror he had on his closet door. Sure enough, his ears were different. The cartilage had stretched itself at the tips, growing into points that increased the size of his ears by a good inch or so. As his mouth stood a bit agape, he noticed a couple of his lower teeth poked into vision more clearly than the others. He pulled back his lower lip and viewed his lower canines, both having indeed grown longer and thicker like tusks almost. "And they'll be even bigger soon" Phil thought to himself, his cock hardening at the apparently masculine image. He lowered his hands and shook his head. Where had such a thought come from? Though his body was so much bigger, he hadn't had any troubles moving in it either. It was as if... he had been like this all along. Was that right? Everything was getting harder for him to think about as attention was drawn more to his stirring crotch and his own musk permeated his nose. Hadn't this been what he wanted all along anyways? He always wanted to be muscular, manlier. Looking at himself in the mirror, he admired his body, looking like a natural bodybuilder covered in a pretty thick, masculine layer of fuzz on his torso, legs, and forearms. His beard was thicker too, higher on his cheeks and a bit longer. His chest puffed out as he lifted an arm and flexed to himself, his thick arm bulging with muscle. The sight empowered him even more, and his cock pressed more strongly against the fabric of his jockstrap. The thing still somehow was large enough to fit him, though it felt pleasantly tight against his cock and balls. One hand moving to start rubbing his crotch through the fabric. He continued to flex, seeing his arm bulge, his pec expand-giving one of his nipples a good squeeze too-, his thick quads which seemed even thicker like tree trunks, his large, hard glutes, everything. The more he flexed, explored, and rubbed, the more turned on he got. His cock started poking through the top of the waistband as it grew and grew. His foreskin had fully grown back overnight too. Flexing a bit more, he slid the jock off and held it in one hand, continuing to admire his large frame. A particularly kinky thought crossed his mind, and he blushed a bit at the thought. He glanced down at the moist jock in his hand and slowly brought it up to his nose. He grunted loudly as he inhaled his own scent in deep. It was just like when he had first gotten the jockstrap, but so much more. He closed his eyes and greedily sucked in the scent, beginning to really jerk his cock with his free hand. As he started jacking, his fingertips and cock started to turn a funny color, going from sickly to pale green to a richer green. The color slowly spread down his body, slowly transforming his meaty hands and turning his cock into a rich green. With the changing color spreading, his cock got more sensitive, and his body seemed to puff out just a tad more. His arms bulged as he jerked, his cock now a solid 12". It all felt so good, but Phil needed to come up for air for a moment. Taking a deep breath, he saw his face again in the mirror. His nose, which had flared out and curved a bit the other day, was now almost vertical, looking more like a snout. It was wide and flat on the front. He blinked a moment before giving a tusky smirk. It looked positively primal, masculine. He took another deep sniff of the jock, and his nose finally finished pushing out into a small snout. Though he admired his body for all the changes he was experiencing, he hadn't started to notice the creeping green going up his arm and spreading over his pelvis. It crept along his body, leaving the areas stronger than before. His ears stretched up another inch, showing the fey influences of his new being prominently. By the time Phil noticed the green skin, it had covered most of his torso, arms, and legs, creeping up his face now too. A small voice in the back of his mind shouted and pleaded for the changes to stop, but the altering skin wouldn't listen. It crept over his chin, his now dark green lips, his snout, and moving up his forehead and pointy ears last. He closed his mind as he struggled with these last parts of the changes. The next time he opened them though, they glowed with a redish fire that overpowered the original brown irises. Suddenly, the changes didn't matter in the slightest. If anything, he was completely enjoying the experience with no reservations. Phil went back over to his bed, dropping the jock on the floor as he fell back onto the covers. He admired his body more as he continued to stroke his green rod. His fingers traced the furry valley between his pecs, the hills of his abs, and the wide sweeps of his obliques. His balls bounced heavily with each stroke, full of testosterone and seed. Everywhere he explored was covered in muscle and dark hair, and the stench of musk still hung lightly in the air. He felt the buildup starting at the base of his cock as he tweaked a meaty, green nipple. Grunting and moaning deeply, Phil tilted his head back and flexed his massive legs hard. Rope after rope of greenish cum sprayed across his huge furry chest and chin, even hitting the wall behind him like last night. The orgasm wracked him for a solid minute before his grunting breaths started to steady. With his seed spent and his body relaxing, Phil was finally able to think clearly again. He sat up in the bed and really got a good look at his new body. It felt at the same time so foreign and natural. It was significantly bulkier than he had been before, but some recalibration allowed him the dexterous movement he had before. Despite how strange his body felt, on the inside he felt... normal. After the frenzy of his libido had quieted down, he could finally concentrate again. Though, feeling his cock twitch slightly as he admired his body and large feet, there were some recalibrations there too. Phil had no idea what he was going to do in his current state; he certainly couldn't go out in the world looking like this. For the moment at least he knew what he wanted to do: take a shower. There was a little nagging in the back of his mind not to do it, but he brushed it aside with the reminder that he would soon be musky again. Unfortunately, he soon realized afterwards that he lacked any clothing to accommodate his new form, and, improvising, wrapped himself in a sheet toga style. He figured he would clean up the room a bit too, ripping the dirty sheets off his bed and tossing them into a hamper. He paused when he saw the jockstrap on the floor. It looked relatively clean, but he could smell the musk he had transferred to it. He picked it up and thought to himself for a moment, wondering at the mysterious power of the object. After a pause, a little thought came to his mind. He smirked and went to the kitchen where the empty box stood from two days ago. He folded the garment and placed it in the box with some wrapping paper, smirking as he considered what doorstep he'd place it.
