Chapter 2 — Fall Break

 

Austin pulled into the driveway of his dad’s house. It was fall break, really just a glorified long weekend but good enough for Austin to make the journey back home from college.

 

Austin closed the door of his brand-new black Ford F-150, his one big splurge after getting his inheritance money. Austin and Jon texted every day and he had called his stepdad a couple times since school had started, mostly to keep Jon company and to check in on his gym progress.

 

Jon was devoted, Austin gave him that… every day he’d text Austin which exercises he had done, a summary of what he had been eating, how long he lifted, everything in great detail. At first they were just in text messages, but soon they were links to a shared Google Sheets page, everything organized in rows and cells. The one thing Austin couldn’t see is what weights his stepdad had been using for all these different lifts, as his dad had set a filter on that so only he could see.

 

The other thing that Austin didn’t see was any pictures. Jon wanted to surprise his stepson on the progress he’d been making.

 

Austin had made progress on his own; he’d put on another 5lbs of muscle and was in top in-season shape. At 6’0” and 235lbs, he was the biggest and best quarterback of his D-3 conference at the small private school he went to. He also had a 3.8 GPA and was acing all of his classes.

 

Austin approached the front door, carrying a weighty duffel bag full of dirty laundry, and found it unlocked. Inside, the house had changed in the last 6 weeks. It was less organized, less neat, and smelled differently; gone was the clean scented candle smell his mom cultivated, replaced with something else. It smelled masculine, fresh but tangy and sharp, a mix of his stepdad’s beard oil and his team’s football locker room.

 

“Jon?” Austin called out, but didn’t hear any response other than music coming from the basement. Austin dropped his bag and made his way downstairs, following the narrow stairs and low ceiling into the basement. As he made his way down, he spotted someone doing pushups. Austin arched his eyebrow, a little confused, because it didn’t really look like his stepdad; this guy was way too big to be Jon. The stranger cranked out pushups tirelessly and with perfect form, quickly going up and down, up and down, squeezing each rep.

 

“Hello?” Austin said. The stranger stopped mid-rep and then twisted around to see.

 

Jon got up from the mat and stood to greet his stepson. “Austin! There you are! Welcome home, son!” he said as he wiped the dripping sweat from his forehead onto his shirt, revealing his furry and hard-looking tummy. He stepped forward and embraced Austin in a wet hug.

 

“J-Jon? Wow, I mean, it’s great to see you, I didn’t even recognize you!” Austin sputtered as he embraced his stepdad. He could feel how much more solid, how much wider, how much bigger Jon was all over. “You… you look incredible, Jon!”

 

Jon stepped back and puffed out his chest, proud and eager to show off his gains to Austin. “You think so? I know I’ve been making some progress but not sure how much you were expecting,” Jon said. His shirt was way too small, soaked and dark under his pits, down the middle of his chest, and across his bulging tummy. The shirt had a cartoon version of his stepson’s college football mascot, the Saint Brian Tigers; the tiger was huge and muscular, bowling past the mascot characters from rival schools.

 

His solid-looking arms strained the tight sleeves, and his chest and traps made the front of the shirt ride up and strain in the middle. A sliver of hairy tummy stood out at the bottom, a slight overhang over his mesh shorts. His shorts, too, looked small and struggled to contain his muscular thighs. His quads bulged out to the sides and down, with ample muscle hanging over his knees and bulging calves. Jon had grown a short beard, the middle of it blonder and longer than the cheeks and sides, with sprinkles of grey spreading throughout; his hair was a mess of short dirty blond curls.

 

“Jon, you… holy shit, I mean, I’ve never seen progress like this before!” Austin exclaimed, flabbergasted. “I knew you had been working hard and following my plan, but this is… wow!” Austin said, and stepped closer. Jon flexed his right bicep and smiled, showing off for his stepson as the muscle pushed back the tight sleeve of his t-shirt.

 

“You like?” Jon asked, an uncontrollable grin spreading across his bearded face. “Your plan has really been great. You did such a good job coming up with it. They must really be teaching you good stuff at college!” A wave of sharp musk radiated from his sweat-soaked shirt and armpits as he raised his arm, the same smell that Austin had smelled upstairs.

 

“Feels solid, dude, way to go,” Austin said as he rubbed the hard peak. It wasn’t the biggest bicep Austin had ever seen, but it was solid and bulging with new muscle. “Just how big are you now, Jon?” Austin asked, a little overwhelmed by his suddenly jacked dad.

 

“Weighed myself this morning, I’m 225 lbs now… gained 50 pounds since you last saw me! Is that good?” Jon asked, stepping back and turning sideways to show his thickness. “I’ve been following your instructions exactly, Austin, and I gotta say, I don’t know why I didn’t start lifting sooner. I’m getting kind of obsessed with it!” Jon said as he flexed his chest, breathing in sharply through his nose and grunting out through his mouth, bits of sweat dripping off his nose and eyebrows.

 

Austin was speechless. 50lbs in 6 weeks? How was this even possible? He laughed at the absurdity of it. “Uh yeah I can see that! These gains are incredible, Jon! You’re almost as heavy as me now, though I’ll still always be taller,” Austin said as he stood closer, to prove his point.

 

“Heh, I guess so. Let’s go upstairs and eat, I’m starving!” Jon said and the two jocks went to the kitchen.

 

Jon’s kitchen had become a mess of Tupperware, half-cleaned dishes, shaker bottles, and jugs of protein powder and supplements.

 

“Jon, you gotta clean this place up. You can’t make as efficient of gains if you’re not organized,” Austin said.

 

Jon looked around the kitchen. “Yeah, you’re right son,” he said.

 

Austin paused for a moment, then sat at the dining room table and looked over at Jon. He wondered what else Jon would do for him. “And make me a protein shake too. You remember the recipe I sent you a couple weeks ago?” Austin said as his stepdad grabbed two clean shaker bottles.

 

“Of course, son, coming right up,” he said. He loaded up the first shaker bottle with two scoops of chocolate protein powder, a banana, oats, peanut butter, olive oil, and water. The second one he did the same but doubled all the solids. “I’ve been doubling the recipe lately because just one wasn’t filling me up. I hope that’s ok!” Jon said. There was so much in the bottle there was hardly room for it to shake.

 

“Yeah Jon, of course. You’re really serious about these gains, aren’t you?” Austin said as his stepdad walked over to him. He really did look amazing, like a fit ex-jock who lifted every day. It was already such a dramatic change from when he last saw him, and Austin got the feeling this was just the beginning.

 

“I really like drinking these shakes, especially since it was you who gave the recipe to me,” Jon said as he stood next to his stepson. “They’re definitely helping with the gains!” He raised the bottle to his mouth, tipped his head back, and chugged, the thick sludge disappearing quickly. “*glug, glug, sluurrrrp, slllrp, glub glug, slluuuuurp slllrp*” Jon rubbed his stomach as he chugged, the shake filling him up as it disappeared. His tummy bulged out round and taut, making his shirt ride up a little, and he took a big breath when he was done. “Grrruff, mmph, *sniff*, that hit the spot! Now I’m ready to make dinner for us,” Jon said.

 

Austin just watched all of this in wonderment. No wonder his stepdad had grown so much since he last saw him. “Jon, you doubled the shake recipe and you’re still hungry?” Austin asked as Jon started cleaning up the kitchen, just like Austin had asked.

 

“Since you told me to start lifting, it seems like I’m always hungry! I guess maybe I’m eating a little too much since I have a little bit of a tummy too, I’m not cut like you are,” Jon said. “Maybe it’s also the beer I’ve been drinking.”

 

“You should keep drinking that, though,” Austin said, the words coming out before he could stop them. Wait, did he want Jon to keep getting bigger and have a bit of a tummy? Yeah, he realized, he definitely did. It would make Jon look even better. Austin adjusted his crotch as he thought about his handsome, older stepdad growing into a proper daddy muscle bear, pushing past 250lbs or maybe even bigger. “The extra calories from the beer, uh, help round out your gains and helps dull joint pain. I read a study about it in class,” Austin lied.

 

“Great!” said Jon as he reached into the fridge and cracked open a cold one.

 

“Make spaghetti, a double batch with 3lbs of beef. And make garlic bread too. I’m gonna take a shower,” Austin said.

 

“That’s a great idea!” Jon replied enthusiastically and started cooking.

 

--

 

The next day, the guys got up and had a big breakfast. Austin again asked Jon to cook, and his stepdad was eager to do so. They loaded up on carbs and protein and headed to the gym together, both of them packing into Austin’s F150.

 

At the gym, Austin was unforgiving, putting Jon through his paces with an intense push day. They started with dumbbell bench press, Austin urging Jon to try 90lb dumbbells that he had never had the courage to try himself. They did decline and incline, Austin making Jon go until failure on every set, pushing him to new PRs. Jon grunted and groaned, his focus intense, his form always perfect, eager to prove himself to his bigger, stronger stepson.

 

Sweat dripped off of Jon’s nose as they went over to do cable flies, Austin making sure he squeezed and paused at the top of each rep. Austin was blown away by how strong his stepdad had become in such a short time; it wouldn’t be long until the 42-year-old caught up to his virile college football athlete stepson if he kept this up.

 

By the time they were done with their workout, their tank tops were a different shade than when they arrived, soaked in sweat and clinging to their pumped-up bodies. They eagerly guzzled protein shakes in the parking lot before riding home, talking about their favorite lifts. They drove home, both of them buzzing with a gym high.

 

They got out of the truck, and Austin walked over to Jon.

 

“Jon, there’s one more thing I want you to do today, and that’s mow the lawn. And I want you to do it shirtless so you can show off all the awesome progress you’ve made to the neighborhood!” Austin said. Jon looked down at his shirt, the Tiger mascot looking darker because the shirt was soaked with sweat. It was an unseasonably warm afternoon, even though it was mid-October.

 

“I don’t know, Austin, I usually wear a shirt when I’m lifting and I don’t think I’m really fit enough to—“ Jon started.

 

“Stop. No way, Jon, look at you,” Austin started. He walked up to his stepdad, reached out and patted his arms and shoulders. “I mean, damn man, you’ve beefed up so much since I’ve been gone. Look at your biceps, I mean really flex and look at them,” Austin said, trying to pump Jon up. Jon flexed his arm timidly at first, but then with more gusto when he looked down and saw them. He lifted his arms up and flexed harder, his biceps bulging into hard, impressive peaks. Austin squeezed and felt Jon’s big arms. They were already almost as big around as Austin’s. “Yeah, jeez look at those big hard guns. You think most guys in their 40s are built like this?”

 

Jon couldn’t help but grin and he scratched the back of his head, making his round bicep peak bulge out more. “Heh, yeah I guess you’re right, son,” Jon said sheepishly. “If you think I should, I guess I will mow shirtless. Why not!” he said.

 

With that, he peeled off his shirt and headed for the garage. He soon emerged with the lawn mower. He was already soaked with sweat from the gym, and after just a couple minutes in the hot sun, he was drenched again, sweat dripping from his arms and chest, his shorts turning darker as they soaked through, revealing a prominent bulge bouncing back and forth as he walked. Bulging dad muscle on display for the entire neighborhood to see, furry and sweaty and hot.

 

Austin sat on the front step and watched his stepdad, his pumped shoulders and biceps gleaming with a sheen of sweat in the afternoon sun. Jon looked over and smiled, seeking Austin’s approval.

 

In that moment, Austin knew he was in charge. The power dynamic of the house had shifted, officially. He was the alpha dog. And Jon would do whatever Austin wished.

 

--

 

Jon finished cleaning up after another enormous dinner and another post-meal protein shake. Austin had Jon drinking 5 shakes a day on top of 5 meals so his growing stepdad had a regular intake of calories and protein. His shirtless torso bulged with muscle and a round, full tummy as he walked into the living room and sat down next to Austin, who was watching football.

 

They had to share the loveseat, because the recliner was piled high with the most recent shipment of Jon’s supplements and protein powder. They both had wide shoulders and took up most of the space, only a few inches between them.

 

“Your season has been going great, son, I’ve watched every game,” Jon said. “You’ve been great reading the defense and shedding defenders. Your increased strength is paying off!” he said, beaming with pride. “I was so impressed with you at the gym today too, bud, I’ve never seen a guy your age be that strong,” Jon said, patting his stepson on the back and rubbing his neck. “Beast!”

 

Austin sat up straighter in his seat and spread his shoulders wide. “Heh, you’re telling me, I’ve never seen anybody make the gains you’ve made over such a short time, Jon,” he said, appreciating his dad rubbing his neck and shoulders. Jon’s raised arm exposed his pits, and Austin could smell the fresh, ripe smell of musk, the kind you get after a hard, sweaty workout. “You’re gonna pass me if you keep this up, old man. But yeah, I had to get a new set of pads, the ones I had freshmen through junior year were too small, too tight,” Austin said and shifted his arms around, flexing his shoulders and traps.

 

The football game went to halftime and the guys switched over to watching World’s Strongest Man on ESPN. Austin got an idea as he saw one of the big strongmen getting massaged between events. “Say Jon, why don’t you rub my shoulders? They’re feeling tight after the gym and it would feel great if you rubbed them. Plus, you owe me as your trainer!” Austin said as he stood up, looking down at Jon.

 

Jon looked up at Austin and adjusted the bulge in his gym shorts, his hard thighs shifting wider to make room for his stepson. “Sure thing, bud, have a seat and let me loosen you up,” Jon said. Austin took his shirt off, revealing his naked torso to Jon. Austin’s wide shoulders framed his broad, meaty chest. Abs studded his stomach, which were covered in a light dusting of brown hair. “Wow, son, you really are jacked, look at you!” Jon said. Austin smirked at Jon and flexed his bicep, the peak bulging up bigger than Jon’s had when they were outside. Austin got a whiff of his own musk; Jon wasn’t the only one stinking up the living room after his workout.

 

Austin sat down and leaned back against Jon’s warm thighs. Jon started rubbing Austin’s hard traps, kneading his fingers into the dense muscles. Austin could feel the rough gym callouses his stepdad had developed over the last couple months scrape against his neck and upper back as he dug in.

 

“Oooooh yeah wow Jon, that feels great,” Austin groaned as his stepdad rubbed harder. “You’re pretty good at this, you know?”

 

“Your mom had me train to be a massage therapist a couple years ago because she said I wasn’t any good at it. Guess I picked up a thing or two. The things we do for love…” Jon said as he leaned down and pressed his forearm and elbow into Austin’s traps and down his shoulder blades.

 

“Uuunnnnnggggg damn that’s it,” Austin moaned as Jon loosened his hard muscles. Austin could feel and smell Jon’s breathing on his neck as he rubbed and rubbed; his breath smelled like protein shake and his beard had a whiff of cedar beard oil. The combination of all the different smells in the room made Austin’s head spin and his cock pulse.  “Feels amazing,” he cooed.

 

“Mmm glad you like it, son,” Jon said, his voice deep and relaxing. Austin could feel Jon’s bulge shift and throb as he leaned harder into his tight muscles. This was clearly turning Jon on, Austin realized. Austin felt a flitter of excitement for the forbidden but undeniable attraction to his stepdad. Seemed it was mutual, to his surprise. He had assumed Jon was straight, but apparently not!

 

Austin took a deep breath and sat up a little bit, creating a little distance between them. He had to take this slower.

 

Austin looked up and saw last year’s strongman champion on the screen, a hulking monster at 6’8” and over 450lbs. He had a flash of Jon somehow getting that big, transforming him into a massive muscle monster with bulging arms and shoulders like the big strongman on TV.

 

Austin knew something extraordinary was happening with his stepdad; no one grew that fast, especially not in their 40s, but somehow Jon was doing it. How far could Austin push it? Jon seemed to love it, totally addicted to the gym, the growth, the lifestyle of being a lifter. Austin knew he had to try. Jon continued rubbing Austin’s back until the football game came back on.

 

“Alright Jon, now it’s your turn. You deserve it after such a long day,” Austin said as he stood up to switch spots. Jon stood up too, and suddenly they were face-to-face, brushing past each other, both of them shirtless. They both grinned awkwardly and then shifted past each other to get in place, Austin on the chair and Jon between his legs, pressing back against the quarterback’s firm thighs.

 

Jon’s traps and shoulders were firm and plump, ruddy from his workout. Austin could feel how much harder and bigger his stepdad was than when he had left him just 6 weeks ago. He could hardly believe it… the hard muscle shifting around in his grip felt nothing like the soft, flat shoulders that were there not long ago.

 

“Ohhhhh, mmmm son this is great, keep rubbing,” Jon groaned. The sounds of football washed over them and Austin rubbed Jon’s shoulders, both of them relaxing but feeling an undeniable tension.

 

When the game was over, they both headed up to shower and said goodnight to each other. Austin could hear Jon grunting and then yelling in the shower… was that his stepdad jerking off? He had plenty of reason to, after the tension he felt between them and the heavy lifting they had done.

 

--

 

Austin threw his fresh laundry and other stuff into the bed of his truck. He was wearing a black tank top with the school logo on it and short white gym shorts that did little to conceal his prominent bulge.

 

“Jon, it’s been awesome staying here the last few days. I’m so proud of the gym progress you’re making. You seem so much happier than last time I had to leave,” Austin said.

 

Jon was wearing a tight grey polo and khakis, as he had work later that morning. “I wish you didn’t have to leave, but I can’t wait to get more workout and diet plans from you, son. I’ll be bigger than ever next time you see me!” Jon said with a spark in his eye. He lifted up his right arm and flexed, the peak pushing back the tight sleeve of his polo shirt and exposing his big bicep.

 

“You better be, or else I’ll be disappointed!” Austin said and lightly squeezed Jon’s bicep. “Jon, there’s something else I want to talk about.”

 

“What is it, son?” Jon said.

 

“I’m so happy with your gym progress, Jon. It’s given you a new direction and given me a project I feel so passionate about. And you know, we have so much money that mom left us. I want to build on this,” Austin said, stepping closer to his stepdad. He put his hands on Jon’s chest and felt the muscles of his pecs through through the tight polo. “I want to see you push your limits and really grow. You understand?” Austin said and looked Jon right in the eyes.

 

Jon looked up at his stepson. He felt a quiver of excitement in his chest, just like Austin had felt the night before. “Y-yes, son, I do understand. More than you know,” he said.

 

“Good. I want you to go into work today and quit your job. You’re going to start devoting all of your time to lifting, eating right, and maintaining the house, got it?” Austin said. “You are my first priority, and I can’t get the most of you if you’re distracted by work.”

 

“Are… are you sure? I mean, I’ll have so much time, and what about money, and,” Jon sputtered, his old insecure self coming out for a moment, but Austin wrapped his arm around his shoulder.

 

“Don’t worry about any of that… dad,” Austin said. It was the first time he had ever called Jon his dad, but after this weekend, it felt right. “I’ve got it all under control.”

 

Jon’s mouth dropped open a little. “Did you just call me… oh son, I’ve been hoping for that for a long time,” Jon said, clearly moved. They hugged and patted each other on the back.

 

“Well dad, I’ve got something else for you too,” Austin said as he reached into his backpack on the ground. “These are tank-tops from the team store at college. I’ve been saving them for the end of the weekend, and you’ve earned them,” Austin said and he tossed them to his dad.

 

Jon caught them; three tank tops, all with different motifs of the school’s football mascot logo, one straightforward and clean, one the old-school logo from the 70s, and the other a more cartoonish one with the tiger flexing his huge muscles over a vanquished rival, snarling and wearing football pads and cleats.

 

“You are to wear these and only these during your workouts between now and when I get back for Thanksgiving break, got it? Take off your shirt and try one of these on, now,” Austin said in a firm tone.

 

Jon did so right away, but struggled a bit to get his polo off. He slipped on the tank top and looked awkward. He wasn’t used to wearing them. “This’ll take some getting used to… and, Austin, these… these don’t really fit! I mean, it’s an XXL,” Jon said. He was right, the tank top was a bit too big for him and sagged off his shoulders and drooped below his waist like a pajama shirt.

 

“You’ll grow into it, dad. I challenge you to make it be too small come Thanksgiving,” Austin said with a smirk.

 

Jon grinned. “You’re on!”

 

Austin climbed up into his huge truck and started it up, the loud diesel engine rumbling. “Oh dad!” he called down to Jon. “One more thing. Expect some delivery and installation guys in the next few days,”

 

“What for?” Jon asked, looking a bit silly in a tank top and khakis.

 

“I’m turning the garage into a professional-grade gym. You’re gonna have everything you need right here at home to get fucking huge. Sound good?” Austin said as he put his sunglasses on.

 

Jon raised his chin up to look at Austin. “Sounds amazing,” he said and an uncontrollable smile spread across his face. He couldn’t wait for Thanksgiving to show the progress he was going to make for his son.
