Pec Growth - Tumblr Posts

I don't watch a lot of Marvel, but I might have to now!





This Summer, try visiting Himbo Beach! It's a relaxing nude beach where you can leave feeling like a brand new man!

When Derek found out that Stiles's favorite sleeping position is to rest his head on his chest, Derek made sure to do extra chest days to give his boyfriend the largest, most comfy pillows.

I tried to inflate this stud's pecs, but it looked odd. So then I tried to shrink his head a bit to make his muscles look bigger, and now he looks like this! Haha, still kinda nice I think.
31 Days of Derek Hale
Day 05: Cursed Tape
Info │ 01 │ 02 │ 03 │ 04 │ 05

“Der!” Stiles voice rang out, dripping with jubilation. “Come see what I just scored!”
Derek grunted as he got out of his chair, feeling tired from his long day at the auto shop. Still, he shuffled down the hall, clad in only his white tank top and sweatpants, freezing when he saw Stiles beaming ear to ear and holding a large cardboard box.
Before he could even ask, Stiles rushed out, “I got a mystery box at the thrift store! Can you believe it?! How cool is that?”
“Mystery box?” Derek grunted, crossing his arms in front of himself as he cocked his eyebrow. “And how much did that cost?”
Stiles shrugged as he carried the box to the living room. “…um, about eighty dollars, give or take…”
Derek’s eyes widened and his jaw clenched.
Stiles obliviously set the large box down onto the floor before eagerly tearing into it, his large eyes alight with wonder over the “treasures” he’d scored for one-hundred thirty dollars. The big box was stuffed full of various items: scraps of fabric, old porcelain figurines, and some VHS tapes.
“We don’t even own a VCR,” Derek grunted, unamused.
Among the pile that his husband was creating, Derek spotted an odd looking VHS tape. There was a gaudy neon background that looked like it was ripped straight of the 80s, with little captions indicating that it was a workout video of some kind. However, the weird part was that there was a blank outline of a person on the front instead of some obscure fitness guru. The title of the odd tape read out: Sweatin’ it to the 80’s! Starring _____!
“What the hell?” Derek scoffed as he picked up the tape to examine it some more— the second his fingers grazed the cover of the tape, Derek felt what seemed like a jolt of electricity ripple throughout him.
The werewolf jerked back, confused over what had just happened, yet he quickly realized that he was still holding onto the tape. Derek tried to relax his grip to let go of it, but his hand refused to listen, instead clutching onto the tape with all of its strength.
“Stupid tape…” he grumbled to himself, stopping once he saw something else start to happen.
Steadily, his white tank top began to change hue, turning from bleached white to a neon blue. As the straps thinned out, the collar dropped down low to his midsection, exposing his pecs to look more like a stringer.
The changes didn’t stop there.
Stunned silent, Derek’s jaw dropped as he witnessed his toned pectorals shudder before pushing out as they gradually inflated. The previously proportional mounds plumped up and rounded, becoming an impressive set of muscletits that jutted off Derek’s chest noticeably. His altered tank did nothing at all to try to conceal them, the enlarged nipples poking out of the sides and demanding attention. His arms packed on more muscle, becoming large and bulging, especially his biceps which rivaled melons. Derek looked down, yet his massive pecs blocked his view of his sweatpants as they tightened against his legs, suctioning to his form to become a skintight pair of spandex that showed off every ridge of his carefully crafted musculature— that was prompt ruined as his legs grew in size, becoming larger. His butt ballooned out as it beefed up and pushed itself outwards. Derek’s eyes widened as he felt a sensation like he was getting harder. When he reached down and patted at his bulge, he almost gasped at the girth package that filled his hands. His cock and balls had inflated to the point where it looked like the larger stud was smuggling a softball in the front of his spandex pants.
When he was done changing, Derek had to have packed on at least fifty pounds of muscle, making him look like some over-the-top workout guru who belonged on the front of those cheesy exercise tapes.
Derek’s face stretched out to form a large grin, despite the panic that he was feeling. The living room shifted and Derek felt as if he were falling, the walls of the room stretching upwards. Derek’s sight rapidly shifted upwards, forcing him to stare straight up at the ceiling. He tried to look away or call out to Stiles for help, but he couldn’t move. All the shocked werewolf could do was smile and show off his hairy muscletits on the cover of Sweatin’ it to the 80’s! Starring Derek Hale!
Blissfully unaware of his husband’s transformation, Stiles finally finished rummaging through the mystery box. “See?” he smiled, standing upright. “There’s tons of cool stuff in here… Derek?”
Stiles looked around for Derek, pausing when his eyes landed on an obscure VHS tape that was on the floor. He walked over and picked it up, his eyebrows rising at the image of a muscled up Derek on the cover, smiling widely. His eyes looked panicked though.
“Derek!” Stiles gasped, clutching the tape close to him. “Don’t worry! I’ll figure something out!” He sprinted out of the house and to his Jeep…
About an hour later, Stiles returned home and set up the VCR in the living room. Once it was connected, he popped the cursed VHS in and pressed Play.
Synthpop blasted over the speakers, and bright neon colors flashed on the screen before a shocked Derek appeared on screen. He was still in his muscled up body, appearing to jog in place.
“Stiles?!” Derek called out on the TV, able to see his husband on the other side. He tried to stop himself from jogging, blushing at how the motion made his inflated pecs bounce up and down. “What the hell happened— Time to get that heart rate up!” His eyes widened at his last statement, having said it was such pep that he sounded like a cheerleader.
Stiles threw his hands up in exasperation.
“How am I supposed to know?” he cried. “How the hell did you get into the TV?”
Derek rolled his eyes as he stopped and started to do lunges. “It’s that damn mystery box of yours!” he accused. “I touched some weird tape and this happened!” He nodded down at his inflated form, wincing as he couldn’t stop working out.
He paused his lunges and started to bounce his pecs up and down.
“And one, and two…” He blushed, but he couldn’t stop the muscled mounds from lifting and slamming back down. Still, he was smiling widely and speaking with immense enthusiasm. “You gotta do lots of reps if you wanna get pecs as big as these!”
Derek couldn’t stop himself from working out and showing off his out of proportion body. The whole time he kept smiling, despite his eyes looking wide and disbelieving.
Stiles, unsure of what to do, figured that perhaps the best course of action was to let the video finish. Plus, he had to admit that Derek looked pretty hot with big, hairy pecs. “Um, maybe… maybe we should just let this play out?” he suggested.
Derek screamed on the inside, but could only place his hands on his hips. “Now that we’re all warmed up,” he beamed, “I’m gonna show y’all some glute blasters!”
31 Days of Derek Hale
Day 12: Bunny Boi
Info │ 01 │ 02 │ 03 │ 04 │ 05 │ 06 │ 07 │ 08 │ 09 │ 10 │ 11 │ 12

“You’ve got to be shittin’ me,” Derek growled as he looked over the ridiculous outfit that was in the bag.
Derek had lost a bet with a fellow alpha, and as punishment, he would have to wear an incredibly embarrassing outfit for the day.
Derek grimaced at the lacy corset that had matching garters, and a cringey set of bunny ears to top everything off.
There was a loud knock on the other side of the bathroom door. “You better move it, Hale,” laughed Nate, the other alpha who was apparently a total freak.
“Son of a bitch,” Derek spat, taking off his leather jacket and jeans so that he could put on the stupid bunny outfit. The alpha werewolf slid on the panties first, rolling his eyes at how small they were. His cock was so big that it filled the tiny pouch to bursting, yanking the tops of the underwear downward to show off his trimmed bush and the base of his dick. Clenching his jaw, Derek pulled on the corset, which was at least two sizes too small for his muscular body. It was nearly impossible to close it shut around his thick waist, and his pecs completely spilled out over the top, his nipples poking out noticeably. It was so tight, in fact, that Derek felt as if his midsection was being squeezed so tightly that it shoved his pecs outwards even more. He put on the lace garters, feeling ridiculous the whole time.
When he was finally all dressed up in his humiliating outfit, Derek begrudgingly opened up the door, revealing a smirking Nate.
“Lookin’ good, Hale,” Nate whistled, making a show of eying the alpha up and down. “Oh, but wait! You forgot something.” He reached over and snatched the bunny ears off the sink before plopping them on top of Derek’s head.
“Gee, thanks,” Derek muttered under this breath, the headband attached to the bunny ears giving him a little headache.
“Well, c’mon, I’ll show you what chores you can do, and then we can call everything even,” Nate boasted as he stomped down the hallway, his broad back swaying with every powerful step he took.
Derek blushed as he took a step in his stupid outfit. His muscles squirmed against the tight fabric, making him have to almost arch his back in order to get semi-comfortable. The action only led to his large pecs being thrusted forward, his nipples resting atop the lacy corset, constantly rubbing against the soft fabric. The way the straps from the corset attached to the garters around his thighs made his steps resemble more of a mincing movement, soft and delicate.
Nate led Derek to a messy bedroom that completely matched Nate’s frat boy attitude. Clothes were strewn all over the floor, the bed was a total pigsty, and there were pizza boxes and empty beer bottles scattered all over the cluttered floor.
“Go ahead and start with my room,” Nate laughed.
“What a fuckin’ mess— Oh!” Derek squeaked when Nate gave his butt a playful smack. His cheeks bounced from the motion, and Derek’s face grew red.
Worse was that his cock twitched for some reason, almost thrusting out of the confines of his small panties.
“Fuck off,” Derek barked, stomping angrily into the messy bedroom, trying to shield his hardening member from the other man.
He snatched a trash bag out of the pile of cleaning supplies, starting to toss a bunch of the garbage into it. As he moved around, Derek’s nipples get rubbing up against the lace of the corset. It must’ve been due to the softness of the outfit, but it seemed as if Derek’s nipples were hardwired directly to his throbbing cock.
The alpha bit down on his bottom lip, trying desperately to resist the electrifying feelings that rippled through him as the corset stimulated his sensitive nips.
“This is so fuckin’ stupid,” Derek growled, tugging the collar of the corset downward to give his nipples some relief. However, once he let go and it snapped back into place, he had to bite back a moan as it started rubbing up against them some more.
As he continued to mince around the bedroom cleaning, Derek’s hard cock kept throbbing with want inside the tight confines of his panties. The cotton was stretched to the limit, and every so often Derek would give in and rub his aching bulge with one hand while using his other to thumb one of his nips.
Derek started to toss the other alpha’s clothes into the hamper. He flitted about the room, hard nipples and harder cock, bending down and grabbing fistfuls of Nate’s clothes. His musky scent clung to every fabric, that manly musk permeating Derek’s senses.
Derek grabbed a jockstrap off the ground, seeing that it was a size XL.
“Ooh, big boy,” he cooed, before flinching and slapping a hand over his mouth. “Why’d I just say that?”
His perky nipples still burned and his cock throbbed like crazy, at full mast. Still, it hadn’t burst through the small panties, and Derek couldn’t help but reach down again to feel himself up. His hand ran over his rock hard cock, freezing as his fingers grazed his bulge.
“I-is it smaller?” Derek gasped, looking over his pecs to the bulge in front of his humiliating panties. Sure enough, the lump in front of his meaty thighs wasn’t as prominent as it had been moments before, looking tight and compact.
Derek quickly tugged the panties downward, paling at the sight of the four inch cocklet poking out of his trimmed bush. With a shaky hand, Derek reached down at his shrunken member, wrapping his fingers around it.
“Oooh,” he moaned, unable to keep his lips shut at the surge of pleasure that rippled through him. Despite the panic that was coursing through his veins, the werewolf couldn’t help but fondle his tiny cock that made him feel even more ridiculous with his massive muscles in such a girly costume. He knew that he should be panicking even more, to tear the apparently cursed outfit off, but his frazzled mind was so clouded over with lust that it was difficult to think about anything else.
“Did I say that you could play with yourself?” Nate’s deep voice bellowed.
Derek jerked back and blushed as the other man stared him down.
Nate smirked as he crossed his beefy arms over his large chest. Derek hadn’t noticed before, but Nate had large muscles that were so big and manly. His pecs stretched his t-shirt to bursting, and his biceps curled out the tight sleeves. His bulge in the front of his jeans was much, much larger than Derek’s diminished one. And manly musk radiated off of Nate in waves, making Derek’s mouth water.
“No, Sir,” Derek answered promptly, his voice light and almost airy. Instantly, he dropped his muscled arms to his side, his tiny cock throbbing as it stood at attention in front of him. The more Derek stared at the other alpha, the more his small cock throbbed and his perky nipples burned with want. His unknown desire was starting to creep up to higher levels, and he couldn’t help but shift his feet under Nate’s gaze, rubbing his thighs together in anticipation.
Nate gave a tsking motion with his finger. “Well, finish up then, Bunny,” he ordered. “Then I’ll let you play with your tiny nub.” He walked away.
“Yes, Sir!” Derek excitedly said, picking up his pace as he minced around the room, his pert little cock bouncing in front of him as he moved.
He didn’t know why his heart raced at the thought of being ordered around by such an alpha like Nate. The frat boy was stacked with such manly muscles, and some of his chest hair curled over the collar of his t-shirt— a stark contrast to Derek’s smooth muscletits that bounced with every step he took. His little nub leaked precum the whole time he finished cleaning. Once he was done, Derek eagerly rushed over to Nate to deliver the good news.
“All done, Sir!” Derek reported, smiling widely at the alpha.
Nate looked away from the TV. He’d taken off his shirt, resting his arms behind his head, letting his musky, hairy pits air out in the open. “Good job, Bunny,” he grinned at Derek. “Why don’t you take your uniform off? Don’t wanna mess it up while you service your alpha.”
“Yes, Sir!” Derek happily gushed, practically ripping his panties and corset off. He paused for a moment as he looked over himself. His tiny, three inch cock was as hard as ever, yet it seemed so small and utterly tiny— especially in comparison to the large eight inches that Alpha Nate had. And even though his corset was off, Derek’s pecs were still pushed upwards and out, looking slightly larger and more bulbous than they should’ve. His nipples were hard and nubby, sticking off his muscletits like little erasures. Something was wrong, this wasn’t how Derek should’ve looked… was it? He didn’t know why a tiny voice in the back of his head shouted that he was supposed to be a manly alpha like Nate, not some sub bunny boy.
Nate unzipped his pants and fished his own cock out, letting his large member bob in the air. “You gonna stand there or are you gonna take care of this?” he bellowed.
Derek quickly squashed the voice in the back of his head and hurried forward, his muscletits bouncing with every minced step he took. Dropping to his knees, Derek leaned forward and hungrily took the entirety of Nate’s cock into his mouth, sucking it like a pro.
“That’s a good bunny,” Nate teased, toying with the bunny ears that were atop Derek’s bobbing head.
“Mmmm!” Derek loudly moaned, his little nub spurting tiny droplets of cum as he sucked off his alpha, loving his role as his muscled up bunny boy.
31 Days of Derek Hale
Day 24: Cow
Info │ 01 │ 02 │ 03 │ 04 │ 05 │ 06 │ 07 │ 08 │ 09 │ 10 │ 11 │ 12 │ 13 │ 14 │ 15 │ 16 │ 17 │ 18 │ 19 │ 20 │ 21 │ 22 │ 23 │ 24

Derek grimaced as he swallowed down the odd tasting protein shake. “That tastes weird,” he spat. “What’s in it?”
Theo shrugged his shoulders. “It’s a new recipe I’m trying out,” he answered, smirking slightly.
The werewolf and the chimera had been trying to work more closely together, for the sake of the two packs in Beacon Hills. As a result, Derek and Theo would try to be more cordial with one another. One such activity that the two pack leaders actually didn’t hate to do together was work out at the gym. There was a sort of playful rivalry that the two engaged in, always trying to out lift the other as they worked out, trying to get more gains.
Being an alpha werewolf, Derek easily out lifted Theo and his muscles were way larger by comparison. The chimera, on the other hand, tended to stick with a more toned physique, not allowing any of his jealousy to show on his smiling face.
Which was why he was all smiles as he offered Derek a drink of his own secret concoction. The mischievous chimera had fought hard to hide his triumphant grin as he’d watched Derek take a hesitant sip of the “protein shake”.
Derek still wiped at his mouth with disgust at the horrible shake that Theo had offered him. “Yeah, I think I’m gonna stick to my usual,” he huffed. “Thanks though.”
Again, Theo shrugged. “Suit yourself,” he happily hummed.
The two men went to starting their workouts, Theo keeping a careful eye on Derek.
Derek, oblivious to the chimera’s staring, went to the chest fly machine, racking up a ton of weight before performing reps. As he worked out, he noticed an odd tingling sensation in his pecs that wasn’t like the normal burn that he’d expected. Instead, this one felt almost electrifying and oddly… good. Really good.
Derek blushed slightly as his chest tingled, his nipples feeling as if they were hardwired directly to his cock. His cock started to stiffen up in his shorts, and as he continued to perform reps, Derek had to hold back a moan.
“Mmmm,” Derek moaned as he tried his best to keep his lips pursed. His blush deepened when he looked over and caught Theo staring.
The alpha werewolf quickly diverted his gaze and tried his best to continue his workout.
Derek was trying so hard to ignore the odd sensations emanating from his pecs that he hadn’t even registered the growing tightness of his shirt until he heard a loud rip echo throughout the nearly empty gym.
He let go of the weights, letting them bang loudly back to the machine. Cocking his eyebrow, Derek looked down at himself, gasping loudly at the large pecs attached to his chest.
“M-my pecs!” Derek stuttered out of shock. “They’re huge!”
Staring downward, Derek’s previously proportional pectorals had been wildly inflated. They jutted out dangerously from his chest, looking round and bulbous. It looked like someone had sliced a soccer ball in two, glueing both halves onto the werewolf’s hairy chest, looking incredibly out of place on his muscular body. Worse for Derek was that his nipples had even enlarged, growing thicker and protruding off of his massive chest like nubby fingers.
Derek blushed when he squirmed in his seat on the machine, feeling how much his chest bounced and jiggled. Oddly, his pecs felt so heavy and cumbersome, and when he moved, he felt an odd sensation of something sloshing deep inside of them.
Theo snickered as he looked the top-heavy alpha up and down. “I’d say so,” he teased. “Those are some serious udders you’ve got there, Derek.”
Derek shoved himself away from the pec fly machine and hurried towards the privacy of the locker room. As he moved, he noticed the arched back stance that he had to take in order to accommodate for his inflated pecs. This caused the enlarged mounds to be thrusted outwards and more into the open, being impossible to conceal. They bounced and jiggled with every step the frantic alpha took, that sloshing sensation growing in fervor.
When he reached the locker room and stared into the mirror, Derek paled at his warped reflection. His pecs and nipples were huge, easily out-shadowing the rest of his impressive musculature, every other body group looking like an afterthought. His jaw dropped, resting upon the cresting pecs that were pushed upwards and out.
Theo, a devilish smirk still plastered on his face, sauntered into the locker room. He crossed his toned arms over his proportional chest as he studied Derek. “They don’t look that bad, Derek,” he snickered. “Maybe we can get you a bra?”
The color gradually returned to Derek’s face as he turned red, slowly putting the pieces together. “You did this to me?” he accused, gesturing down at his massive chest.
“Duh,” Theo scoffed. “I grew tired of always being the small one, so I did some research and found that a really good growth formula contains alpha milk. Hence, all I needed to do was get you to produce some.”
“‘Alpha milk’?” Derek repeated, looking down hesitantly at his large pecs, frowning when he couldn’t anything past their bulbous size.
Theo walked over and didn’t give the alpha any warning before he reached around and grabbed Derek’s meaty pecs.
“Oohhh!” Derek couldn’t help but moan as his muscletits were fondled. Despite his panic and frustration over having his chest altered, he couldn’t ignore the surge of pleasure that rippled through him. In addition to increasing in size, his pectorals also drastically increased in sensitivity. Every touch from the other man’s hands lit up pleasure receptors that Derek had never had before. His knees buckled and his head rolled back as he was felt up. No amount of sex or playing with his cock could ever compare to the brilliant sensations on his chest, and deep down, Derek felt himself craving more.
Theo began to thumb Derek’s nubby nipples, and the werewolf felt as if he’d explode at any second. His heavy pecs lurched and he felt that sloshing inside of them grow even more; and Derek swore that his pectorals began to feel slightly larger.
Derek tensed up, shooting his load. However, instead of cumming, his nubby nipples squirted out a white substance. The pressure in his muscletits subsided the slightest bit, but Derek felt something else bubbling deep within him. He tried to swallow it down, but the alpha werewolf couldn’t help himself.
As his nipples leaked, Derek bellowed out a deep, “Moooo!”
He was so caught up in the feeling of pleasure that left tingles all over his skin, especially his burning nipples, that Derek didn’t even have time to feel humiliated over that fact that he’d mooed like a cow.
Meanwhile, Theo strategically placed his bottle under the alpha’s leaky nipples, collecting the milk that had seeped out. Placing the cap on it, he grinned widely.
“We’ll have to do this more often, Derek,” he happily said. “There’s a lot of guys out there who’d give a fortune for some alpha milk so that their muscles can grow bigger. And just think, it’s all thanks to you and these udders of yours.”
Derek wanted to be angry, to lash out at the chimera for turning his pecs into large muscletits. However, Theo reached out and teasingly flicked a protruding nipple, causing a lustful haze to cloud over Derek’s mind.
“Mooo!” Derek bellowed again, his giant pecs jiggling with want.

"Coach," Evan blushed as he gestured at his muscletits, "that protein powder you gave me only seems to be helping my pecs grow. And not only that, but... um, they're really sensitive. Like really, REALLY sensitive."

I saw the video and I couldn't resist! I think he looks better this way anyways.

Oops, I completely forgot to tell that jock that there's a side effect to his growth potion I'd given him: the bigger his pecs get, the dumber he gets. If he's not careful, he'll end up as some big-titted himbo. Oh well, I'm sure he'll figure it out...

Ryan Terry at the gym, buying some new shirts online since his pecs keep outgrowing his old ones.
Since your box is cleared can I request a pec to muscletits story or morph of old 2000s gay porn star Caesar?

[I could not, for the life of me, find a pic of him that I could morph well. Sorry!]
Let's travel back in time to the mid/early 2000s, back to when Caesar was active in his porn and competitive bodybuilding career, and he's getting ready to step out on stage...
The crowd roared with applause as Caesar waddled out on stage, his massive muscles glistening underneath the stage lights. Every crevice of his immense musculature shone onstage, illustrating just how massive his muscles were. And the tiny blue poser that barely contained his enormous cock oozed masculinity, making the massive muscleman the awe of many other men in the crowd, many of them wishing for one night with the pornstar bodybuilder.
Caesar moved from pose to pose, nailing every position. His muscles bulged with power and he had a cocky grin on his handsome face as he moved, knowing that first place was well within his grasp.
The giant bodybuilder's stance faltered slightly when he felt cool air blow over his large body. The coolness of the mysterious air caused his pert nipples to harden and poke out off his pecs, making him blush slightly.
Caesar's jaw dropped in shock when his pecs then shuddered and started to inflate. His proportional mounds of muscle grew like balloons as they began to protrude off of his chest. They pushed out and rounded, forming an impressive set of muscletits instead of pecs, capped by large nubby nipples that were seemingly perpetually hard. His pecs grew so large that they blocked the stunned stud's view of anything below them, and his agape jaw brushed the top of them as he stared down in shock.
Even the audience was shocked, before erupting into even louder applause at the bodybuilder with the ludicrously large pecs that were more so muscletits.
Caesar blushed and rushed off stage, noting how he had to arch his back in order to support the new weight on his chest. This only served to push his new muscletits out further into the open though; and his face was bright red as his inflated chest bounced and jiggled with every step he took.
Luckily for the larger Caesar, the big-chested bodybuilder was very resourceful, and his new pec-fucking videos that were posted online proved to be very popular.
Flash-forward to modern day, after Caesar retired from porn and decided to focus on physical training, the muscle daddy with huge muscletits now helps other men grow their pecs to enormous sizes.
Caesar's huge muscletits turned out to be a blessing, and if you ask him nicely, he'll let you give them a squeeze.
Chris Evans hasn't been pulling views lately as Captain America. The producers at Marvel have the idea to improve him a bit; statistics show pecs and ass pull more eyes to the screen. He's under contract, so they don't need to ask. Even if he wasn't, its permanent, so what else is he gonna do?

"You son of a bitch!" Chris Evans roared as he stormed into the producer's office.
The hunky actor's face was bright cherry red as he struggled to move around with his warped proportions. The normally proportional, toned hunk was now a curvy himbo, with pecs so large that they could only be referred to as "Muscletits", and an ass so large that it needed its own zip code.
Chris Evans tried to wear some of his normal clothing, but his larger proportions made them look skin tight on him. His pecs had inflated to the size of small melons, protruding off his chest at a ridiculous angle. His noticeably enlarged nipples poked against the thin fabric of his shirt, the cotton rubbing up against them making his cock throb in his pants. His rotund booty was so large and round that it looked like the actor was smuggling a pair of basketballs in his pants, constantly jiggling and shifting with every step Chris took.
"What's the problem, Mr. Evans?" the producer innocently asked.
"'What's the problem'?!" Chris cried out, holding out his arms to show off his warped body. "Look at me! I look like a damn himbo! Now turn me back!"
The actor's body had been transformed into its current curvy form last week after a meeting with his management, which had claimed that they needed to help Chris Evans boost his image ever since he quit being Captain America. The actor had been on board, unaware of the actual plan that was in store. After taking a mysterious supplement, Chris had been horrified to witness his body morphing into its current himbo state.
The producer mock frowned and typed away at his computer. "Sorry, Mr. Evans," he said, "but we have a contract. You gave us permission to do anything in our power to help boost your sales."
"B-but..." Chris tried to protest, looking down at his altered body, but his muscletits blocked his view of anything south.
"And," the producer continued, "we've managed to get you signed back on with Marvel, and our data suggests that your new tits and booty will be a massive draw for customers."
Chris Evans paled at the thought of romping around in skin tight Captain America suit, his muscletits constantly hindering his movements, and his big butt jiggling behind him tantalizingly.
But then his cock throbbed even more and began to leak precum into his tight boxers despite his humiliation.
"Fine," the curvy hunk relented, "when do we start?"

“Here’s your coffee,” Brandon said as he handed Lance a white cup.
The other man just grunted as he took the offered cup.
Brandon bit down on his lip expectantly, eying his manager cautiously as the cup was brought up towards his lips. Ever since Lance had taken on the manager position at the sporting goods store where they worked, work has been a nightmare. Lance was impatient and arrogant as hell, barking orders at every other employee and seeing himself as higher than all of them. He always strutted around the store like he was top dog and it was annoying everyone else, especially Brandon, who had been hired on at the same time as Lance.
Lance took a sip of the coffee, grimacing as he swallowed. “That’s really bitter,” he muttered, eying the other man up and down. “Did you add the cream and sugar as I’d specified?”
Brandon, a smirk forming on his face since the seller had claimed that only a sip was needed, shook his head. “Nope,” he smiled widely in the small office where they were. “I put something else in there, something I think you’ll enjoy a lot more.”
The manager jerked back in his seat at his desk, looking at his subordinate in shock. “You spiked my coffee?” he asked incredulously. “You realize I can have you arrested, let alone fired, for that…”
He was cut off when one of the buttons on his uniform polo popped off, clattering onto the small wooden desk before him. He scrunched up his brow in confusion and looked down at his shirt in time for another button to pop off, making him gasp when he saw why.
Lance’s previously toned pecs were inflating at a rapid rate. The small mounds were packing on meat as they rounded and puffed out away from his chest, starting to form a shelf. Even his nipples began to enlarge, hardening and poking conspicuously against the straining fabric of his polo.
“Wh-what’s happening to me?!” Lance panicked as he grabbed at his large muscletits, which still expanded under his exploring hands. He stood up and wobbled as the new additions to his chest threw him off balance.
Brandon couldn’t help but stare in awe, knowing that the potion he’d snuck into his manager’s coffee would have some sort of effect, but not like this. He felt so turned on as he watched the inflating man panic over his warping proportions, his cock starting to tent out his uniform khaki pants.
Meanwhile, Lance’s khakis looked like they were vacuuming around his own cock as they started to stretch over his growing ass. The stud whimpered as he looked over his shoulder, paling at the sight of his cheeks packing on size just like his now massive pecs. His bubblebutt continued to inflate until there was a loud rip that echoed throughout the small office. Lance turned around, giving Brandon a full view of the giant ass that had pushed itself through the large tear it had created. His underwear struggled to contain the massive globes, eventually riding up them, resembling more of a thong than briefs.
The warped Lance looked down at himself in horror, trying desperately to piece together what had just happened to him. Moments before, he had been toned yet lanky; but now he was more curvy with thick pecs that obscured his view of below and a giant ass that bounced with every tentative step he took.
All the while, Brandon looked at his manager, smirking as he watched the new himbo try to come to terms with his transformation.
“What happened to me?” Lance whimpered, noting his limited range of movement as his arms kept colliding with his inflated pecs as he tried to feel around his warped body. He took a step forward, wincing when he had to adopt a new stance thanks to his inflated proportions. He had to arch his back due to the massive pecs on his hairy chest and his giant ass kept wagging back and forth, almost as if it were advertising itself.
“Stop worrying and relax,” Brandon said in a calm voice.
“‘Stop worrying’?” Lance repeated incredulously. “How can I stop…” He trailed off when an unknown sense of calm washed over his new body, making him feel incredibly at ease. He was still confused over how his body could’ve changed so drastically, but he couldn’t bring himself to show any of the panic he’d felt mere seconds ago.
Brandon couldn’t help but smirk at the situation before him. “I think this going to be a better fit for you, Lance,” he grinned. “From now on, I’m the manager, and you’re my personal assistant. Got it?”
Lance wanted to argue, to demand to know why the other man was so calm. However, when he parted his lips, he was surprised to hear himself say, “Yes, Sir.”
“Go out on the floor and greet the customers,” Brandon ordered, walking around the desk and sitting down in the large chair. “And make sure to show off for them.” With a flick of his wrist, he waved the former manager away.
Lance’s heart sank in his inflated chest as he felt his legs start to propel him out of his old office. He grimaced as he realized that he was walking out on the store floor with his newly globular asscheeks on display for all to see as they bounced and swayed with every step he took. His pecs were so big that they made his polo end above his navel, looking more like a cut off. His nipples poked through the fabric for all to see, completing his himbo look that was sure to attract lots of attention.
The himbo spotted a man with a dad bod looking over some of the shoes and he felt himself saunter over, a seductive sway in his hips. He internally winced when he stopped in front of the older man, his inflated pecs bouncing with unknown want as his eyes hungrily ran up and down the man’s form.
“Can I help you, Stud?” he practically purred, his eyes widening at how he’d addressed another man. Lance had never had a single gay thought in his life before, yet there he was in a new gay body calling another guy a stud. He wanted to run off and hide, yet the orders he’d received from his new boss forced him to stay put.
The man with the dad bod eyed Lance and smirked. “You sure you’re up for it?” he winked.
Despite screaming at himself to stop, Lance turned around and presented his enormous new ass at the man, giving it a little shake and making it bounce wildly. “I’m positive I can, Sexy,” he moaned. “Why don’t you follow me to the fitting room, and I can show you how I take care of our customers?”
The dad bod man nodded and followed behind Lance to the fitting rooms, all the while the new himbo screamed on the inside over what had happened to him. However, his cock was hardening in his pants as he closed the door to the fitting room.
All the while, Brandon sat back in his new chair and propped his feet up onto his desk as he watched the live feed from the cameras that peeked inside the fitting rooms. He felt himself grow hard at the sight of Lance in his new body bent over and getting fucked by some random guy. Lance was tugging on his larger nipples as he was fucked and his mouth was open indicating that he was moaning loudly. His eyes, however, were panicked and disbelieving.
“I love this job,” Brandon contently sighed as he continued to watch.
I hope I’ve come to the right place… I want to wake up as the man I was meant to be: muscular, handsome, and voracious.
I’ve just never been able to get into working out, so now I find myself entering my thirties with an early-onset dadbod — but I know that if I had the right start, I’d be able to keep it up and be a real fucking man.

If we go back in time and do a little twist of fate, making it so that you'd begun to enter the gym immediately as soon as you could, then...
BWOMPH!
You felt your previous body literally explode with muscle, a large weight placed upon you from all over.
"Whoa..." you couldn't help but mumble, loving how much deeper your voice sounded. Looking downward, all you could see was the great expanse of your massive new muscletits as they jutted far off in front of you. You cumbersome arms were hanging awkwardly at your sides as they rested upon your flaring lats. You took a shaky step forward, your wide thighs rolling over one another as they constantly pressed together.
And that's when you noticed how good it felt to have your newly enlarged muscles rubbing up against itself constantly. Like, really good.
Your cock sprung out and tented your workout shorts noticeably, just from the sensation of your bowling ball sized biceps shifting against your enormous pecs. You had to stifle a moan as you took a step forward, your quads rolling against one another and thrusting your rock hard cock out further in front of you.
All of your clothes were skintight, the squeezing sensation mimicking someone running their hungry hands all over your new bodybuilder form, making your roll your head back and bellow out a moan as you were constantly felt up.
You even had to tug your stringer down to give your excruciatingly sensitive nipples a reprieve. However, you didn't account for the gentle breeze from your A/C unit blowing over the hard nubs, making your cock throb like crazy.
You couldn't help but flex and feel up your inflated muscles which were extremely sensitive, making every touch you felt feel like pure sex. You were a moaning, slutty muscle monster, unable to stop groping himself as many of the other musclemen began to surround you and watch your show, some even starting to join and worship your gigantic form.
Testing a New Supplement

Here's a fun story I wrote for a contest on Gayspiralstories. I didn't place, but it was still fun to write! I'll have to write some more!

“So, what is this exactly?” Viktor asked as he examined the pink capsule pill that was handed to him. It looked like an ordinary pill from any generic vitamin store, but it was allegedly some sort of miracle drug on the cusp of a science breakthrough.
Ethan adjusted his thick-rimmed glasses as he animatedly gestured at the pill. “It’s the latest and greatest in pharmacology,” the nerd explained. “I’ve been working day and night all year to develop this drug. It’s a world class steroid that will help guys build mass, almost instantaneous.”
“‘Instantaneous’? Bullshit,” Viktor scoffed as he studied the pill some more.
When Viktor’s college roommate, Ethan, had eagerly rushed back to their dorm to announce that some members of his biology department were assisting with the development of the new miracle steroid supplement and needed volunteers (paid volunteers), he’d immediately brought a prototype over to Viktor.
Viktor practically lived in the gym, perfecting his body so that he could maintain his position as the star player on the college baseball team. His body was blessed with toned and impressive muscles, and Viktor loved to show them off. He frequently wore tight shirts that displayed his chiseled pecs, and form-fitting jeans that cupped his toned butt and allowed a sneak peek at his sizable bulge. The jock was a total hunk, and Viktor knew it. And he absolutely used his good looks to his advantage, earning himself a reputation as a total ladies’ man on campus, sleeping his way through sororities left and right.
Viktor was known as a total alpha.
It was ironic that he’d gotten stuck with Ethan as a roommate.
Ethan was a total nerd, through and through. The short, skinny dweeb was so utterly tiny, and he wore thick glasses that made him look all buggy. It was obvious that the little guy had a thing for his hunky roommate; and despite having zero interest in guys, Viktor would sometimes tease the little guy by walking around their shared dorm in nothing but his boxer briefs, letting his chiseled pecs be on full display for the nerd to drool over.
Even now as Viktor held the little experimental pill in his grip, he was clad in just his mesh shorts, having just returned from the gym. His pectoral muscles were pumped from chest day.
Ethan shrugged his narrow shoulders. “That’s why the biology department’s paying you thirty dollars, to find out.”
“True,” Viktor hummed. “Thirty bucks is thirty bucks.”
Viktor popped the pill into his mouth, swallowing it down dry.
“Great!” Ethan virtually cheered. “Now all we have to do is monitor and record the results. How’re you feeling now?”
“I feel fine,” Viktor snorted, rolling his eyes at the nerd’s eagerness. He couldn’t help but chuckle inwardly at the thought of some sort of brand new steroid promising results in a few minutes. If anything, he figured he’d just get a minor stomach ache later in the night. “Maybe I got a placebo— UUGHhhh!”
Viktor felt all of his powerful muscles tense up at once, making it look like he was flexing. His body felt really warm, as if he’d just finished a marathon, sweat starting to drip down from his pores in a snap. However, the jock’s attention quickly became alerted to the fact that his impressive seven-and-a-half inch cock rocketed straight to attention, tenting out his gym shorts noticeably.
At first, the stud blushed at being rock hard in front of the small gay guy, but his mind was quickly overcome by a heavy haze of lust. His cock throbbed and ached for release, and Viktor could barely control himself, instinctually reaching down to tear his shorts away so he could take care of it.
Ethan chuckled as the large, alpha stud jerked himself off. Viktor wanted to bark at him and tell him to go away, but he was far too concerned with what he was starting to feel— or what he wasn’t feeling. No matter how hard or long he tugged on his hard cock, he couldn’t feel the regular jolts of pleasure emanating from it.
Viktor grit his teeth as he jerked himself off, but he was getting nowhere near climax. In fact, he could only feel his sexual tension starting to build, his knees weakening and his heart racing as he grew desperate to get off. He even knitted his eyebrows as his throbbing cock elicited zero sexual responses.
“Uhhhh, what’s happening?” Viktor whined, his voice cracking as his cock continued to spasm.
“Just relax,” Ethan said, his voice low and calculating. “You’re a part of a medical science breakthrough.”
Viktor’s face was cherry red as his large bicep flexed with power as he jerked his hard cock, all to no avail. He then winced when he felt his other muscled arm moving on its own accord, without any thought of his own, reaching around himself to his backside. His eyes widened when he felt one of his thick fingers pausing above his tight hole.
“OOOhhhh!” Viktor squealed with pleasure as he inserted a finger inside. His toes curled and his eyes rolled back as he fingered himself in front of his roommate. Viktor had never been penetrated before, and while he maintained the slightest coherence to be begging himself to stop, he’d never felt such pleasure. Viktor’s embarrassment was quickly clouded over as the stud heatedly fingered himself, adding another and then a third one, his mouth wide open as he loudly moaned like a needy slut.
Waves of pleasure crashed over the moaning jock until he could feel a sort of pressure starting to grow inside of him, getting larger and larger until it felt as if a bubble burst.
“GGNnnuuaaa!” Viktor cried as he came, his thick cock spasming as he blew his load all over his muscled chest. His fingers still securely lodged in his ass, Viktor’s massive pecs heaved as he tried to catch his breath after possibly blowing the largest load of his life. “What the fuck was that— uuughhh!” He tensed up, his cock shooting straight up and blowing another large load, his muscles twitching with masculine power as he came.
“It’s working!” Ethan exclaimed excitedly.
Before he could ask what the nerd had meant by that, Viktor felt his impressive muscles tense up as he seemingly was stuck in a perpetual orgasm. His cock kept throbbing and cumming, shooting load after load as the stunned college jock moaned loudly with each burst. Viktor looked down, his face beet red from humiliation before going ghostly white when he noticed something horrible.
Every time his cock blew a load, it grew smaller and smaller. It was still rock hard, but as it throbbed and came, it got yanked further into his body, getting tinier by the second.
“Wh-what!?” Viktor sputtered as he came and reached down at to grab at his shrinking cock, but then he felt something else behind him.
As he shuffled his feet, Viktor felt an unknown jiggling sensation emanating from his backside. The panicked stud looked over his broad shoulder and gasped loudly as he witnessed his proportional butt shudder and pull away from him, growing larger and rounder with each passing second.
“What’s happening to meeeee?” Viktor moaned as he kept cumming, panicking as his cock shrank and his butt grew, all the while the other man kept eying him hungrily as he changed.
Viktor’s ass ballooned out from his back, defying gravity as it blew up. It jutted out at a near ninety degree angle from his back, forming a perfect shelf. The cheeks bounced and jiggled from every slight move that the frantic stud made, sending bolts of electric pleasure straight to his cumming cock. Even his thighs packed on a little meat to accommodate the increased weight at his backside, growing closer together as they constantly rubbed against one another, forcing his tiny cock out front and center.
His butt grew so large that his fingers were forced out of his hole, not able to reach, and the growing sexual tension-fueled pressure inside of him grew to obscene levels, making Viktor desperate to feel stuffed again.
“Uuughhh!” Viktor shrieked as he blew his final load, left spent and gasping for breath as he rested a hand against the wall. His mind tried to piece everything together, but all he could seem to really focus on was the unsettling feeling of emptiness that his giant bubblebutt felt.
“It worked!” Ethan victoriously cried, eying the microdicked, bottomheavy stud with a devious glance.
With a loud gasp, Viktor was finally able to recompose himself, his mind filling with panic over his mysterious transformation. He mobbed past the smaller man, rushing down the hallway. His gait resembled more of a waddle with his thickened thighs, and as he moved, the stud winced as he felt his massive, new cheeks bounce and roll over each other. What was even more alarming was how each movement of his massive ass sent shockwaves of pleasure straight to his small cock, which was still rock hard.
“Fuck!” Viktor shouted when he confronted his new form in the bathroom mirror.
His ass wasn’t just big, it was enormous! Viktor’s face was stark white as he examined his new physique. His butt had inflated to such large proportions that he could see the sides of his rounded cheeks from the front. His muscled torso kept its same size and shape, his massive pecs looming over a trimmed waist that then widened out to a giant pair of cheeks that were about the size of beach balls. No matter how impressive his pecs were, no matter how cute his smile was, and no matter how round his biceps were, Viktor knew that his giant bubblebutt would now forever be the focus of his body. As he turned to and fro to examine his new body, his huge ass bounce and jiggled, seemingly in constant movement.
The former alpha frowned when he saw the tiny one inch nub that his cock had become. It was still rock hard, but it was barely noticeable at its new size. Out of instinct, Viktor reached down and grabbed it, only able to hold it with his thumb and index due to how small it had become. It was embarrassingly tiny.
“What’s wrong, Stud?” Ethan asked as he walked up to him, enjoying how the larger man shuddered when he ran an admiring hand over his cresting ass.
“What— how— why?” Viktor sputtered as he tried to piece together what had happened to him. He knew for a fact that no one would ever look at him the same, that he’d immediately lost his alpha status thanks to the small cock he now possessed.
“You just helped with a scientific breakthrough,” Ethan told the bottomheavy hunk. “We were developing a supplement to see if we could turn the biggest, manliest jock into a musclebutt slut.”
Viktor’s eyes widened at what he heard. “Wh-what?”
“Just think about it: you are Exhibit A now. You’re proof that the straightest alpha male can be turned into a needy bottom who is built to bring pleasure to other men. That massive booty of yours is the perfect cushion for an alpha male to dominate, and that tiny cock of yours will make sure that all of your pleasure receptors are in that big butt now. See? You’re now the perfect bottom!”
Viktor’s pecs heaved as he tried to process what he’d just learned. Not only had his cock shrank and his butt inflated, but apparently the drug had also turned him into a needy bottom slut.
The jock looked over at the nerd beside him, the air in his throat drying up. Despite his panic, Viktor couldn’t help but notice how cute Ethan looked with his soft brown hair and little dimples. He felt a slight pressure in his crotch and looked downward, expecting to be hard. His little one inch cocklet looked unchanged, yet when he reached down and felt it, Viktor paled when he realized that he was in fact rock hard. He was just too small to notice.
But the throbbing in his tiny cock paled in comparison to the deep hunger that he felt in his inflated butt. The jock shuffled his feet with want, every shift and ripple from his booty making his nub throb even more. An intense itch formed deep within his inflated ass, and it grew with such fervor that he could barely think about anything else.
“What is it?” Ethan smirked, noting Viktor’s pained expression.
Viktor’s face burned bright red, and before he registered it, he heard himself blurt out, “I need you to fuck my slutty butt!”
“Well, go ahead and get to the bedroom then,” Ethan hummed.
On cue, Viktor hurried out of the bathroom towards Ethan’s room. His face was bright red due to the nonstop jiggling from his big butt and the absent sensations from his crotch, but his desire to get stuffed overtook it all.
The jock threw himself onto the bed on all fours, arcing his back and shoving his bubblebutt towards the nerd.
Viktor let out a low bellow as the other man entered him, moaning as he began to pick up speed. His inflated butt rippled as he thrusted himself back, sending massive shockwaves of pleasure throughout him, making his bulky muscles twitch. The entire time, his tiny cock uselessly sputtered out an embarrassingly small amount of cum.
His massive bubblebutt elicited nothing but pleasure, and before long, Viktor basked in the glow that getting fucked by the other man gave him. He couldn’t stop the slutty moans from escaping his lips, and the jock shoved his face down into the pillow as he flexed his cheeks, eagerly milking the nerd’s cock.
Ethan tensed up and came; and as he was filled, Viktor’s eyes nearly rolled to the back of his head. He struggled to catch his breath as his entire body tingled, feeling electrified.
Steadily, as the sex-driven fog cleared from his frazzled mind, the shock of his transformation settled in.
“Ohhh, you can’t leave me like this!” Viktor begged, pawing at his pathetic nub and wiggling his hips, his massive butt jiggling wildly.
“Don’t worry, Vik,” Ethan cooed, “the supplement should’ve made it so that you’ll love living your new life as musclebutt.” To prove his point, he roughly swatted the jock’s enormous cheeks.
“Ooh!” Viktor squeaked as his microdick spat out a meager amount of cum.
-- -- --
“Ready?” Ethan asked, dressed up in a suit that made the normally geeky young man look handsome. He peeked behind the curtain, marveling at the large crowd of people from the scientific community who attended the symposium.
Viktor swallowed loudly as he shuffled his feet nervously, his tiny nub throbbing as he examined his roommate in his black suit. “Um, I guess so,” he muttered unconvincingly.
The smaller man mock frowned. “What’s wrong, Big Guy?” he asked, placing a sympathetic hand on Viktor’s broad shoulder.
The former college jock blushed as he stared at the mirror that was placed backstage. Instead of wearing a suit like the nerd, Viktor had been instructed to wear his jockstrap… and nothing else. The usual cocky stud used to have absolutely zero problem with showing off his muscled body, and he could vividly recall peacocking in the gym with his massive chest muscles on full display for all to gawk at. However, now he felt incredibly exposed and humiliated.
His enormous bubblebutt protruded out the back of the jockstrap, being lifted slightly by the constricting straps. Instead of looking confident, the jock looked hesitant to parade around with his beach ball sized rear shifting and bouncing behind him. Still, no other pair of pants would fit him, leaving him wearing next to nothing and just letting his big booty be on full display wherever he waddled. Worse was that the front pouch was loose and baggy, illustrating how much the hunk was lacking.
“Um, n-nothing,” Viktor relented. It’d been three weeks since his transformation, and although he was still horrified over being turned into a slutty, microdicked power bottom— he was still incredibly turned on. Night after night, Ethan or one of his old teammates from the baseball team would take turns fucking him. Although he’d hated having such a big booty at first, Viktor’s massive cheeks brought the jock nothing but pleasure, and he even began to look forward to getting fucked, eagerly awaiting the next time a thick cock would be deep inside of him.
Even now, his little nub was rock hard and barely even tenting out the front of his jockstrap, just from noting how cute Ethan looked in his suit. That familiar needy sensation formed in his ass, and Viktor wondered if they had time to squeeze in a quicky before Ethan needed to go onstage.
Ethan checked his watch. “Whelp, it’s time for me to go out,” he said. “I’ll call you out in a sec.” He playfully swatted Viktor’s bubblebutt.
“Ooohhh!” Viktor moaned, shooting a meager load into his jockstrap. It was nothing like what it used to be, but the stud still panted as he tried to catch his breath, feeling tingles on his inflated butt from where the other man had touched it.
The crowd erupted into applause as Ethan walked up to the podium. After tapping the microphone, he began to speak:
“Good evening esteemed members of the science community. For years, us nerds and small tops have been typecasted as bottoms. But no more. Gentlemen, I am here today to declare that we have successfully created a new supplement one-hundred percent guaranteed to turn the biggest, most cocky alpha male into the neediest buttslut around. May I present, Exhibit A!”
That was Viktor’s cue.
After taking a deep breath, Viktor waddled out onto the stage.
The crowd erupted into loud cheers and awed gasps as the bottomheavy stud waddled out towards the podium. The whole time, Viktor’s face burned with humiliation and he felt as if he’d burst into flames at any second; however, his little cocklet throbbed with intense want as he moved. His massive bubblebutt shifted and jiggled behind him, many of the men in the crowd whistling at him in a catcalling manner.
Ethan smiled warmly at the altered jock and then continued. “Our new supplement will increase the libido of the male, as well as the size and sensitivity of his glutes. It also programs him to respond sexually to any male stimuli. And in order to solidify his status as a bottom, it will cause the phallus to reduce in size by upwards to ninety percent.” He turned to Viktor. “Exhibit A, if you may.”
Viktor’s face looking like a tomato, the jock hooked his thumbs into the straps of the jockstrap and tugged it downward.
The crowd marveled at the jock’s one inch microdick, and despite how humiliated he was, a bead of precum was already starting to ooze out Viktor’s nub.
Viktor glanced out over the crowd, realizing that everyone in attendance was male. Immediately, his nub throbbed even more and he couldn’t help but flex his massive butt with want. He was embarrassed and wanted nothing more than to hide somewhere off stage, but another part of him instantly began to fantasize about getting his big butt stuffed full of cock after cock— from every guy in the audience. He was so caught up in his horny daze that it took the jock a moment to realize that he’d been massaging his inflated cheeks with both hands, unable to stop even when he became aware.
“And for those of you who are more chest guys, we have been trying to develop a supplement to suit your needs. Exhibit A was given a dose this morning with his morning coffee,” Ethan explained.
Viktor jerked back in shock at what he’d heard. “Wait, what— uughhh!”
Vitkor spasmed and felt as if his chest were on fire, like he’d just finished an intense chest day at the gym. His nipples tingled, and then the bottomheavy jock’s jaw dropped as he watched his pecs begin to inflate and round out. The muscled mounds grew outwards from his chest, obstructing his view of anything below them. His nipples even increased in size, inflating into large nubs that stuck off his muscletits tantalizingly, looking more like thumbs.
“Oooohhh!” Viktor squealed as he came, his cocklet shooting out a tiny amount of cum for the entire audience to witness. The now curvy stud paled as he poked and prodded at his muscletits, embarrassed to find that his enlarged chest also elicited the same pleasurable sensations as his massive ass.
The crowd once again cheered as they admired the curvy jock with large pecs that protruded off his chest like a shelf, nearly swallowing his neck; and an even bigger butt.
Viktor knew that the college jock with the proportional body that women lusted over, was gone. And in his place was a curvy, microdicked powerbottom who begged for cock on the daily. He paled at mental images of himself strutting around the gym with a massive butt and humongous pecs… but then he thought about all of the handsome jocks on his baseball team. A lot of them had large muscles as well, and even larger cocks.
Viktor’s nub throbbed again as it hardened, and the stud couldn’t help but reach up and toy with an inflated nipple.
“Do you have anything to say, Viktor?” Ethan asked him, a smirk on his face.
Viktor’s brain was taken over with his horny daze, and despite himself, the former jock dropped onto all fours and wagged his bubblebutt towards the nerd. He even noted how his muscletits squished together as he rested on his hands, having to reposition his arms around their exaggerated size.
“Just please fuck me!” Viktor begged, his deep voice cracking by the surge of lust that took over his body. The stud let out a low, bellowing moan as Ethan slid himself inside of his tight hole, almost loving how many other guys were watching the whole ordeal.
His massive booty jiggling and his enlarged pecs bouncing with every thrust, the moaning Viktor basked in the immense pleasure that washed over him in tidal waves. Sure a small part of him was horrified over what he’d become, but a louder part loved every second of it— getting fucked every day and having his body built for nothing but the upmost sexual pleasure.
Viktor loved his massive booty and enormous pecs (and even his little cock), and he knew deep down that he’d need to convince other guys on the baseball team to take part in the drug trials.
But he’d need to have them fuck him before their cocks shrink, of course.

This stud's a little annoyed because the gym employee at the front desk told him that if his muscletits get any bigger, he's going to have to wear a bra.
(Just something I did while trying to work on shadows)
