#ultram0th

Bodybuilder Antoine Vaillant’s phone lit up with a text: Merry Christmas! 

Antoine fidgeted relentlessly at his desk, hissing under his breath as he typed up an email that he needed to send to a sponsor. His impressive gym-built biceps would jostle against the obscenely large pectorals that were attached his muscular chest every so often as he struggled to type on his keyboard, making the top-heavy hunk shudder. His trimmed beard did little to cover up the blush that was taking over his face. Speaking of which, the prickles from his jaw scrapping up against the tops of the hairy muscle mounds sent sparks of pleasure throughout him even more, rendering him nearly incapable of typing a single sentence. The dark hairs that covered his pecs only intensified the hypersensitivity, and the sensation of his button-down rubbing up against his hard, nubby nipples should have been enough to have him blow a load in his pants on the spot.

However, despite the near overwhelming pleasure the older bodybuilder was feeling at his desk, his rock hard seven inches refused to give him any release. Instead it throbbed as it was placed tightly against his muscled thighs.

The bodybuilder frowned as he looked in the mirror that was in his office. He took great care of himself and his body. As a professional bodybuilder, Antoine knew the ins and outs of the gym, and it clearly showed. At 6’0’’ and approximately 250 pounds of meaty muscle, he was a beast of a man. Plus, during his offseason, he’d allow all of that bulging muscle to be covered in manly hair. He’d loved to saunter around, clad in tight pants and form-fitting button-downs that allowed him to display his alpha status. He completely ruled the gym and the little office he’d worked in to take care of his social media accounts. Everyone knew that he was stud— a total man’s man.

However, instead of the alpha male he was used to seeing, Antoine hated the image reflected back at him. He still retained his hard-earned muscles and his handsome looks, but all of that took a backseat to the enormous pecs he possessed thanks to a certain Christmas wish.

The bodybuilder looked as if he were smuggling two basketballs underneath his shirt that was several times larger than his usual ones, but was still strained to bursting. He’d been unable to button up the top three buttons, allowing the deep hairy top cleavage of his muscletits to be on full display. His erect, nubby nipples poked against the fabric, looking like a pair of thumbs. His pecs were so huge that they ballooned outwards at the sides as well, completely engulfing his thick neck and making it appear as if his head was resting directly atop the muscle mounds. His giant pectorals completely ruined his manly and proportional physique, causing him to come off as some freakshow who has beachball-sized pec implants.

But even more embarrassing for the stud was how sensitive they now were. It felt as if all of his body’s erogenous zones had traveled throughout Antoine’s body to center in solely on his pecs, with the epicenters being his nubby nipples. Sensations as simple as his shirt rubbing up the hairy mounds felt as good as masturbation, and Antoine’s cock always rocketed to life whenever his massive arms accidentally brushed up against his muscletits (which was often).

But that wasn’t the worst part…

“Mr. Vaillant?” a light voice called as Erik, a college intern helping to manage his socials, poked his youthful face into the bodybuilder’s office. “Your sponsor wanted me to remind you that you need to make a post of the new protein powder.”

Ever since what had happened, Antoine couldn’t help but admire some of the other men in the gym. He hated how jittery he’d get whenever he’d see another man’s pecs (which were obviously much smaller than his) pressing against their shirt or when he’d spot the large bulge in a guy’s pants. 

As he looked at Erik, he couldn’t help but admire the green tint to the young man’s eyes or how full his lips looked. The guy must’ve been an athlete in school, because his trimmed frame had some toned muscles that were still pretty sizable, albeit nowhere near as huge as the champion bodybuilder’s.

Antoine’s blush deepened when he saw the twenty-one year old guy’s green eyes try their best to avoid his huge pecs. “Tell them I’ll do it tomorrow,” he grunted, waving the skinny guy away with a buff arm. “And it’s 1930. Go home.”

Erik nodded, not-so-subtilely taking one last look at the older man’s muscletits before turning around. “Yes, Sir,” he said. “Have a nice weekend.” He left and closed the door behind him.

Antoine just huffed and slammed himself away from his desk, desperate for release. As he walked to the parking garage, Antoine tried to ignore the sight of his reflection in the car windows that showed his altered posture that had to account for the heavy muscle mounds. He walked with his back arched with shoved his pecs out into the open, as if advertising them for more to stare at. Even worse was that there was a slight bounce to them with every step the stud took, making his nipples rub up his shirt over and over again, his knees going weak.

The muscle hunk hopped in his truck and barely had time to close the door behind him before his frantic fingers undid the buttons of his shirt, desperate to give his sensitive chest some much-needed relief. Antoine practically tore his shirt away from his hairy torso, his inflated pecs heaving as he sighed deep breaths of relief, his larger nipples still burning with desperate want.

“This is getting real fuckin’ old,” Antoine groaned aloud as he struggled to catch his breath, his hard cock twitching wildly in his pants. Despite how irritated he was, he was also so incredibly horny, his sensitive pecs sometimes clouding over his frustration.

The top-heavy DILF took a moment to adjust his seat in his truck, having a little difficulty with his inflated pecs pressing against the horn on the steering wheel a few times. Antoine still wasn’t used to driving with his arms fighting to reach the wheel with his enlarged chest constantly getting in the way. He would have figured that after a few days, he’d be semi-accustomed to it, but he still gasped and whimpered loudly whenever his biceps would graze a nubby nipple whenever he turned the wheel. The rumbling from the powerful engine sent rippling vibrations throughout the truck, constantly making his pecs jiggle the slightest bit, which was shockingly enough to send little darts of pleasure throughout the stud. He had began to unwisely drive without his seatbelt, risking the ticket because whenever he wore it, the strap slipped deep into his cleavage and made him howl like a slut.

Doing his best to ignore the feeling his hypersensitive pecs brought him, Antoine drove straight home. Every so often when he’d be at a red light, the stud would grope his massive chest for a while, moaning loudly like a slut as he played with his tits. He’d be so caught up in the euphoric sensations that emanated from his sensitive muscletits, that he’d only be knocked out of it whenever the car behind him would honk because the light had turned green.

The embarrassed stud sped the rest of the way home, practically sprinting inside once he arrived.

Inside, Antoine barely fared any better. His massive pecs kept jiggling with every movement he made, and they kept getting in the way as he tried to cook himself dinner. No matter what he did, Antoine was helpless to do anything besides stimulate his sensitive chest, which led to him ceasing all of his nightly chores in order to just feel himself up.

As he gripped handfuls of his tits and gave them a squeeze, Antoine couldn’t hold back the low moans that bellowed out of his muscled frame. His face was bright red with humiliation, but the embarrassment he felt paled in comparison to the intense surges of pleasure that his muscletits brought him. His nipples were almost worse— every time he brushed up against them, his knees buckled and his cock throbbed even harder.

As he played with his chest, Antoine couldn’t help but think back to how this had all started. He’d been asked by some random Santa Claus out on the street what he’d wanted for Christmas. The bodybuilder had playfully replied with, “A big set of tits.”

Then the rest was history. 

The morning after the interaction, Antoine had been horrified to wake up and discover that his pecs had magically been inflated to nearly four times their normal size.

Antoine’s masturbation session was interrupted when he heard a knock at the door, making the top-heavy bodybuilder groan with annoyance. “What?” he barked out impatiently, his nubby nipples burning with want as soon as he let go out of his muscletits.

“Mr. Vaillant! It’s me, Erik!” the small voice of his tiny assistant called out from the other side of the front door. “You forgot to take the product home with you for your posts!”

Antoine sighed but opened up the door nonetheless. Like clockwork, as soon as he stared at the younger stud in his doorway, he could feel his cock twitch a little more and his nipples continued to burn with want.

Erik, in turn, couldn’t help but not-so-subtly stare at his boss’s inflated chest, the bulge in the front of his khakis starting to harden. His cock lengthened down his leg and he hungrily licked his lips at the sight of Antoine’s huge, hairy muscletits that were out in the open.

Despite having his warped pecs out for the younger guy to gawk at, Antoine couldn’t deny the surge of lust that he felt. “Fuck it,” he grunted as he grabbed Erik’s hand and yanked him inside. 

Antoine dropped to his knees and fished Erik’s uncut seven inch cock out of his pants. The bodybuilder leaned forward and thrusted his inflated chest out more, sliding his assistant’s cock deep into the cleavage of his pecs.

“OOhhhhh!” Antoine moaned loudly as a slut as the younger man pecfucked him. The bodybuilder grabbed the back of Erik’s toned butt and kept him in place as he thrusted himself up against his cock, driving it deeper into his pec cleavage. 

Nothing he’d ever done compared to the intense sensations that Antoine was feeling from his chest now. No sex he’d ever had with a woman nor playing with his own pecs was even close to the same. Sure he was embarrassed over his actions and over having his perfect musculature warped into a top-heavy caricature, but Antoine couldn’t bring himself to truly mind in the moment.

If walking around with ultra-sensitive muscletits that were way too big and cumbersome for his bodybuilder physique meant that he could get pecfucked by cute guys, then he was game.

His moans grew into pleasured cries as Erik reached down and began to thumb the bodybuilder’s nubby nipples.

Erik tensed up and came, blowing his load all over Antoine’s heavy tits, coating them in his spunk. Antoine’s forgotten cock had already blown its own load and was already hard and ready for a second round.

“Holy shit,” Erik panted as he leaned down and gave one of Antoine’s big muscletits a playful squeeze. “Merry Christmas, Antoine.”

Antoine shuddered at the feeling of his chest being squeezed, and all he could do was respond with a bellowing moan.

Muscle model RJ Portales worked out in the gym at the bench press as he worked on building up his world famous chest. The former Army Officer had developed quite the Internet following because of his plump pecs that he would often bounce for men to drool over. Therefore, the stud made sure to keep his fans happy, working out religiously and having numerous Chest Days to ensure that his muscletits were always big and juicy.

RJ kept his ear buds in, blasting his music as he worked out, allowing him to drown out any distractions. This prevented him from noticing the small group of smaller nerdy men who were staring at his muscular form, trying to hide behind one of the large workout machines.

They watched intently as the stud worked out, his meaty pecs glistening with sweat as he got them pumped up from his presses. RJ would grit his teeth and bellow out a manly grunt as he lifted the bar, making some of the smaller guys swoon.

The leader of the sneaky group pulled out what resembled a comic book ray gun straight out of a cheesy sci-fi movie, aiming it directly at the top-heavy stud. With a mischievous smirk, he squeezed the trigger.

A flash of light flickered in the gym as a beam darted towards the unsuspecting RJ, hitting him square in the chest.

RJ let out a surprised gasp the very second he felt the ray hit his pecs. He didn’t have time to wonder too much what it was that had struck him, because in a flash, the hunk felt his whole center of gravity shift. 

RJ paled when it looked like the walls of the gym were starting to stretch as they grew upwards; however, it didn’t take long for RJ to realize that the room wasn’t growing, but that he was shrinking. “What the fuck is going on?” the hunk panicked, bristling at the chipmunk squeak that his voice now possessed as he got smaller and smaller.

His clothes weren’t affected by the shrinking, and they grew baggier and looser by the second. RJ’s shoulders slipped through the collar of his too big tank top as he got smaller, and his jockstrap and shorts fell to the ground. RJ looked into one of the posing mirrors in the gym, finding a tiny semblance of relief when he saw that his body still maintained all of its bulging proportions as he grew smaller. However, that relief was short-lived as he continued to shrink.

Eventually, RJ got so tiny that he started to get swallowed up by the bundle of clothes that had been skintight mere seconds ago. He felt like he was swimming in fabric, extremely disoriented from his now minuscule stature. He could hear booming thuds from footsteps quickly approaching, and the shrunken stud felt his heart start to race as he hoped that whoever found him could help him.

The group of nerds swarmed the bundle of clothes that were on the gym floor, the leader reaching through them to find the small man inside. He felt the squirming RJ and yanked him out, the group of guys gasping as they saw the tiny man.

RJ couldn’t have been more than six inches tall, and he fit in the lead nerd’s grasp perfectly. All of his muscles and proportions looked the same— they were just on a much smaller body now. The formerly tall muscle stud felt so incredibly tiny as he was held by another man whom he totally would’ve dwarfed at his previous size. However, now he looked like a top-heavy action figure as opposed to an online model.

“Please!” RJ squeaked in his high-pitched voice. “You gotta help me! I don’t know what happened, but I got smaller all of a sudden!”

The nerds chuckled at his helium-esque voice, and the leader reached over with his free hand to feel RJ’s large pectorals. Using the tip of his index, he lifted the mounds up and let them bounce back down, feeling them squish under his touch.

“Whoa, these things are huge!” the nerd mused aloud as he continued to play with RJ’s muscletits.

“H-hey! Knock it off!” RJ blushed, annoyed that despite how panicked he was, he couldn’t deny the feelings of pleasure that rippled though him at having the now much larger man play with his tits. He was completely helpless to do anything but let himself be fondled, his cock even hardening.

One of the other nerds walked up to the group, holding what looked like a hamster cage in his hands. It was designed to look like a scale model replica of the gym; yet, instead of a variety of machines, it appeared that the only ones in it were meant for chest exercises.

RJ was stunned as he was placed inside the cage, wincing when he heard the door slam shut. His eyes went wide as he took in the sight of all of the chest workout machines, and when he saw the bowls of food and water in the corner.

The lead nerd chuckled again as he crossed his arms in front of his thin chest. “Yeah, that’s right, RJ,” he laughed. “It took us a while, but we managed to turn you into our little muscle pet. But don’t worry. We made sure to give you everything you need in order to keep building up those muscletits of yours.”

RJ gulped as he took in the words he was being told. He frowned when he looked around at the bars of the cage that was now his home. His cock was begrudgingly still hard, and the more he thought about it, the more he realized that he’d have no choice but to work out and make his pecs get bigger and bigger.

And worse was that he immediately thought about how great it’d feel to have his bigger pecs fondled by the larger nerds. He blushed as he cock throbbed at the thought.

“O-okay,” RJ squeaked as he walked over to the bench press, his hard cock bobbing in front of him with every step. He racked up the weights and set to work being a good muscle pet so that his new owners could enjoy his muscletits up close and personal.

Online model Shawn Calder scrolled through his Instagram feed. He’d just posted a question to his followers on his story thread: “What do you want for Christmas?”

A simple, innocent enough question in order to boost engagement. Plus, the fact that the picture he’d selected to go along with it was one of him shirtless, flexing his plump pecs in the mirror would only serve to encourage engagement tenfold. Shawn wasn’t oblivious to the fact that a large percentage of his followers were mainly there to lust over his impressive pectorals, which the stud was all too happy to show off in his numerous pec bouncing videos which always garnered tons of likes.

As the hunk relaxed on his couch, he scrolled through some of the answers from his holiday question. His followers responded with typical things like consoles, food, etc. However, one of the responses caused Shawn to bellow out laughing.

What I want for Christmas is your big sexy muscletits.

Shawn chuckled as he looked down at his t-shirt, easily seeing his mounds that were pressed against the tight cotton. Playfully, he gave them a little flex.

“Well, I’d hate to disappoint ‘em,” Shawn joked to himself, grabbing the end of his t-shirt. The hunk froze though when he felt an odd pressure forming on his chest— more specifically: his pecs.

Before Shawn could voice any of his concerns, his eyes widened as he saw his already sizable pecs begin to balloon outwards. The muscle mounds grew to an exaggerated size, tearing his t-shirt to shreds as they enlarged. Shawn’s meaty pecs grew up and out, rounding as they inflated to the size of basketballs. They got so large that the stud could already feel how drastically limited his range of motion was as he repositioned his arms around their crazy size, and when he looked downward, they completely blocked his view of anything south. Even his nipples enlarged, hardening and forming large nubs that were about the size of the man’s thumbs as they protruded off his new muscletits.

“Wh-what—?!” Shawn panicked as he stared down at his new upper shelf. The top-heavy hunk stood up, having to alter his stance to account for his now massive muscletits. This resulted in him having to arch his back, which only shoved his pecs further out. And when he took a step, his pecs bounced and jiggled.

The hunk hurried into his bedroom to examine himself in the mirror, blushing wildly at the way his constantly bouncing chest sent little darts straight to his hardening cock.

Shawn gasped loudly when he stared at his warped reflection in the mirror, paling at the massive pectorals that were attached to his chest. They were insanely large and made the rest of his muscle groups look smaller by comparison. Shawn even shivered a bit when his stubbled chin scraped the top of his muscletits, even that minor sensation feeling oddly pleasurable.

“This can’t be happening…” Shawn muttered as he studied his top-heavy physique. He gave his pecs a tentative squeeze, letting out a loud moan as his knees went weak at the ripples of pleasure that emanated from his pecs throughout the rest of his body. He was left panting, his massive chest heaving as his cock tented his shorts out in front of him.

The stud began to look around his room, his stomach dropping as he realized that no shirt could ever cover his juicy melons. The thought of himself walking down the street with such big muscletits jiggling around for everyone to gawk out made Shawn blush. Sure he loved to show off his (previously normal-sized) pecs online, but the thought of doing so twenty-four/seven with such mammoth tits made him feel utterly humiliated.

…and a little excited.

Despite his embarrassment and bewilderment over his inflated pecs, Shawn didn’t hesitate to start bouncing them like he would frequently do in his videos. The muscle mounds leapt and crashed back down, rippling with the movement as he flexed his tits. All the while, his hard cock throbbed and ached with want.

But Shawn didn’t notice.

He upped the ante and reached up to palm both of his muscletits, giving them a rough squeeze.

“Ooohhh!” the stud moaned loudly as he pursed his lips, playing with his tits as if it were his new form of masturbating.

In a flash, all of Shawn’s panic and humiliation over having his pecs morph into gigantic muscletits evaporated, and the top-heavy stud hungrily began groping himself.

Shawn bellowed out another slutty moan, pursing his lips as he groped and played with his muscletits. His cock twitched and leaked precum the entire time, completely going untouched. The stud began to thumb his enlarged nipples, feeling as if a lightening bolt rippled right through him.

“Uunnnghh!” Shawn squealed as soon as he grazed his hard nipples, blowing his load in his shorts. As he tensed up and came, Shawn could feel his massive chest bounce and jiggle, loving the sensation.

As he panted, his enormous pecs heaving, Shawn struggled to piece everything together. Not only had his pecs somehow inflated to the size of melons, but evidently they were also super sensitive. Shawn felt a meager spark of humiliation over the idea of going around, only able to get off if he was having his new muscletits played with.

But then the stud thought about having another man grope his chest and suck on his hard nipples, and Shawn’s cock rocketed straight back to life.

Without a moment’s hesitation, Shawn grabbed his phone and went live on his OnlyFans.

“I’ve got a Christmas gift for you all,” the top-heavy Shawn purred as he recorded himself bouncing his muscletits in the mirror for his followers to see.

Hunky actor Glen Powell chuckled as he examined the dog mask that he held in his hands. It had been something that he’d received as a Christmas gift from one of the producers from his new movie. It was definitely a gift that was out of the norm, but Glen had accepted it either way.

He could vaguely recall seeing masks like these online, and guys would often wear them shirtless to flex their large muscles with the mask on.

Laughing to himself, Glen couldn’t help himself and he tugged his shirt off, exposing his toned chest muscles. He then pulled the dog mask on, adjusting it to fit perfectly onto his face.

Glen continued to laugh as he lifted a muscled arm, flexing his bicep in the mirror. The fun-loving actor couldn’t help but bust out into hysterics as he flexed while wearing the obscure mask, thinking that this was absolutely a hilarious prank that had been pulled on him.

He went to pull the mask off, his laughing ceasing as he realized that it was stuck.

“What the hell?” Glen hissed as he grabbed onto the ears of the mask with both hands, giving it a rough tug. Still, the mask refused to budge even a centimeter, as if it were superglued to the hunk’s head.

He even tried to find the bottom seam, but it was as if the mask had been suctioned to his skin, preventing him from even getting his fingers into the mask to pry it off.

“Damn it,” Glen huffed angrily as his biceps flexed with power as he tried to yank the stuck mask off. “Why the fuck won’t this thing… Grrrr!”

Glen paused at the odd growl that had escaped his lips. It had been completely unintentional, yet it had felt totally natural.

The hunk cleared his throat as he stumbled towards the kitchen to look for some butter. He opened up the fridge, growling again when he noticed that he didn’t have any butter or anything slippery at all that could help him get the mask off.

“Really… er, WOOF!” Glen barked, literally. The actor’s eyes went wide as saucers as the dog bark escaped his lips. Again, the hunk cleared his throat and tried again. “Woof! Woof! Hrmm… Woof!”

Glen’s heart started to speed up in his muscled chest as he tried to speak. However, no matter how hard he tried to form words, he couldn’t say a single thing besides dog barking. He tried again to pull the mask off his head with all of his might, barking and growling the entire time.

Then Glen tensed up as he felt some sort of invisible force pushing down on his broad back, forcing his legs to buckle. The force grew so strong until he tumbled onto the floor of his kitchen, landing on all fours.

“Woof! Woof!” Glen panicked as he tried to stand back up but was unable to. He tried to balance himself on his legs, barely making it a few inches above the floor before crashing back down onto all fours like an animal.

Glen was so caught up in barking and crawling around on the floor that he didn’t notice someone entering his home until he looked up and saw the older man smirking down at him, his arms crossed in front of his beefy chest.

“Well, well,” the older man mused, “looks who’s finished their transformation into a Good Boy!”

At the phrase “Good Boy”, Glen felt something inside of him snap. He couldn’t help but happily start barking excitedly as he rushed forward to the other man on all fours, his butt wiggling behind him wildly as if he were wagging a tail.

Deep down, Glen was aware of his actions, but he couldn’t stop. Had the dog mask not been covering his face, the other man would’ve been able to see that it was cherry red… albeit with a big, goofy grin on it from the extreme excitement he felt. Worse was that the more he stared at the other man, the harder he felt his cock get.

Glen felt utterly humiliated as his hard cock bobbed in front of him, but he couldn’t even bring himself to hide it as he continued to happily bark at the older man’s feet.

“Good boy,” the older man cooed playfully, tracing a large hand over Glen’s broad back, sending a shudder through the actor that made his hard cock throb. “Let’s go ahead and get you home so we can show you off to your new owner. My husband’s gonna be so happy. He’s aways wanted a dog.”

Glen screamed on the inside as he felt a collar being slipped comfortably around his neck. The older man led him by a leash, walking him out of his home and onto the busy sidewalk. He was mortified at his hard, naked body being on full display as he crawled on all fours like a dog; but he couldn’t show any of his embarrassment. 

Instead, Glen kept his head held high, his chest muscles puffed out. His body knew that he was a good dog, and he couldn’t resist letting out another bark at the excitement he felt over getting a walk. He was such a good boy.

Hunky actor Cody Christian wore a deep frown on his handsome face as he got dressed into his clothes for the photoshoot. The stud buttoned up his shirt, taking time to admire his form in the mirror.

He’d spent years working out religiously in the gym, making sure to build up his muscles to a decent proportional build. It had gained him loads of fans and even offered numerous roles. His pecs popped nicely, yet modestly. His biceps had a nice curve to them, illustrating that he could play the tough guy roles due to the strength they exuded. Lastly, he never neglected legs, ensuring that they matched the rest of his toned body perfectly.

And yet, the photographer of the shoot had had the nerve to suggest that Cody try to work out some more and gain some size when he’d shown up.

“I don’t need any more size,” the actor grumbled under his breath. He was already big enough, so he figured that the photographer had no idea what he was talking about. “He probably wants me to look like one of those roided freaks…”

The moment the words left Cody’s full lips, he began to feel a tingling sensation ripple throughout his body, making him break out into goosebumps. Before he could react, Cody gasped as he saw all of his body hair beginning to pull inwards.

The stud ran a disbelieving hand over his now smooth body, shocked that he felt as if he’d just freshly shaved all over. Cody was never really hirsute, but he wasn’t too into manscaping.

Cody didn’t have time to voice any of his confusion or even try to come up with an explanation before his whole body tensed up, all of his muscles starting to inflate to obscene proportions.

Cody’s calves inflated to the size of footballs, his thighs growing to such wide sizes that they pressed against each other, forcing him to widen his stance. His jeans tore to shreds, landing on the floor in a tattered mess at his feet. He blushed as his butt puffed out, resembling enormous beach balls that were attached to his lower back as they jutted out. The growth traveled upwards as his shoulders broadened to a wide degree. His traps inflated, swallowing up his neck. Arms that were previously toned and proportional were blown out of sync as his biceps rounded out, rivaling the size of bowling balls. His bigger arms rested on lats that flared out, forcing them to hand akimbo at his sides. Cody’s modest pecs ballooned outwards, blocking his view of anything below him. His nipples stretched out and puffed up, looking large and nubby from the huge growth. His shirt followed suit with his pants, leaving him in nothing but his stretched out underwear.

As a final touch, Cody’s stomach dropped as he watched his stomach begin to balloon out too, forming a large roid gut. It continued to bubble out, jutting far out in front of him, with his enormous muscletits resting on top of it. He couldn’t even see his cock and balls that were hidden beneath his rotund belly.

The tingling sensation ceased, and where a toned actor had been stranded a minute ago was an over muscled bodybuilder with a massive roid belly.

“Wh-what the fuck happened to me?!” Cody panicked, his voice sounding much deeper now than it used to. There was no scale around, but the inflated hunk estimated that he must’ve gained at least one-hundred pounds of pure muscle. He looked like a freak!

“Cody Christian to the set, please!” the photographer called out.

Thanks to his panic, it took Cody a little bit to realize that his inflated body had started to move on its own accord. Cody’s face was bright red as his walk resembled more of a waddle as he struggled to move around with such bulky muscles hindering his movements. His thighs kept rolling over each other, and his arms were stuck out at his sides, making him lumber about.

The stud huffed annoyedly when he tried to exit his dressing room, but his broad shoulders both banged against the doorjamb. He had to turn sideways and squeeze himself through the door, his big roid gut making it difficult to fit.

He waddled out onto the photoshoot set, his heart racing in his beefy chest.

The photographer was all smiles as he looked up at the bodybuilder Cody. “Perfect!” he beamed. “It looks like you took my suggestion to heart.” He raised the camera and started to take pictures of the massive muscleman.

On instinct, Cody began to run his hands over this smooth muscles seductively. He ran his hands over his huge roid belly before massaging his inflated pecs. He tried to stop himself, but it was impossible. The hunky actor paled as he realized that not only had his muscles and gut been inflated to incredible proportions, but he couldn’t even control it anymore.

Cody lifted both of his massive arms above his head, forming a double biceps poser. As he flex, he kept his handsome smirk on his face while his big belly jutted out in front of him with every pose and flex he made for the camera.

“You look like such a big, roid-abusing muscle freak,” the photographer laughed as he continued to take pictures of the new bodybuilder. “Maybe you should consider getting even bigger and bigger…"

Muscular model Alessandro Cavagnola was attempting to do something festive for his OnlyFans account by getting more into the Christmas spirit. The hunk opted to do a sort of tree decorating live video, where he would place ornaments on his plastic tree that was in his living room— and he was clad in the tightest boxer briefs that were perfectly suctioned to his body. They showed off every curve of his plump bubble butt and they showcased his impressive package. His large, round pectorals hung over his chiseled abs, and whenever he grabbed an ornament of the box on the floor, Alessandro not-so-subtly would flex a bowling ball-sized bicep for the camera.

Alessandro’s plan worked! Out of the corner of his eye, he could see that there were tons of adoring fans who were lusting over his holiday livestream, each one of them eager to see his plump muscled body.

A confident smirk on his sexy face, Alessandro bent over flirtatiously as he reached inside the box for another ornament. He even gave his bubble butt a little wiggle, loving the chiming notifications that pinged out from his computer.

Alessandro paused when he spotted an ornament that he didn’t recognize, grabbing it and pulling it up to his face to examine it. The piece in question was an ornament in the shape of a muscle man who flexed a large bicep. He was clad in skimpy briefs and had a wide smile on his painted face. The artist had paid extra attention to the chest muscles and even crafted a large lump in the man’s groin area.

Alessandro couldn’t help but chuckle, figuring that he must’ve bought the ornament and then forgotten. After all, a muscle man tree decoration would help his theme. He held the glass man up in front of the camera for his viewers to see.

“Kind of looks like me, right?” Alessandro asked in his deep baritone, throwing up his free arm to flex a bicep just like the ornament. As he posed, a cold air blew over the room. The sudden chill caused the hunk’s skin to erupt in goosebumps and his nipples to perk up.

The unexpected sensation also caused the muscle man to accidentally drop the ornament, sending it shattering onto the hardwood floor.

“Damn it,” Alessandro hissed under his breath, stepping away from the shattered glass at his feet. He looked back up towards his webcam and gave a sheepish grin. “Shit happens. Gotta find a replacement.” He shrugged his broad shoulders.

His first instinct was to go grab the broom to clean up the mess real quick, but his thoughts were quickly distracted when his seven inch cock immediately rocketed to life. Alessandro felt as if his already impressive libido was cranked up to an obscene level as his cock throbbed like crazy in front of the camera, creating an obvious tent in his skintight boxer briefs. His hard perky nipples burned with want, and his skin began to tingle.

He opened his mouth to wonder what was going on, but all that came out was a deep moan.

Alessandro’s confusion deepened when he felt himself throw up his right arm to flex his bowling ball-sized bicep again. It was something he’d done unconsciously and without any say so on his end; but his confusion quickly morphed into panic when he realized that he couldn’t stop holding his pose.

No matter how hard he tried, the muscled hunk’s heart began to beat faster in his beefy chest when he couldn’t drop his arm. Alessandro strained his muscles as hard as he could, but his large bicep wouldn’t budge. It was stuck in its impressive pose, made all the more worrisome when Alessandro discovered that he couldn’t move the rest of his body at all. His feet were superglued in place and his meaty pecs weren’t heaving as they should’ve been due to his rapid breathing. His hard cock still stuck out in front of him despite his horror, which was mixed with an intense horniness.

The hunk felt his mouth stretch out into a goofy grin that was alight with zeal as opposed to fearful.

The tingling sensation over his skin grew stronger by the second, leaving it looking almost glossy. It even began to reflect the bright lights from the Christmas tree, getting harder and harder.

Alessandro felt his center of gravity drastically shift. The room appeared to stretch outwards and up, as if it were rapidly growing all around him. However, despite his frazzled panic, Alessandro knew that the room wasn’t growing, but that he was shrinking.

The muscleman watched as the room looked larger and larger as he got smaller, until the shrinking finally stopped. Based off the way he was staring directly at the base of his table in his living room, he estimated that he couldn’t have been taller than six inches or so.

His flexed muscles hardened, solidifying his single biceps pose. As a final touch, he felt his still hard cock freeze up too, leaving the stud permanently flexing and hard… and incredibly turned on despite how freaked out he was. 

Alessandro couldn’t see that the webcam managed to pivot lower so that his audience gained a full, uninterrupted view of his transformation into a sexy, muscleman Christmas tree ornament. The smiling, hard ornament sat right where the muscle stud had stood a few minutes ago, perpetually flexing and hard.

Alessandro could hear the chat sound off, his viewers gawking and gushing over how hot of a Christmas ornament he made and how they hoped that this would be an annual event for the muscle stud…

Actor Zane Phillips was relaxing at home with his boyfriend, Froy Gutierrez. The two guys were lounging on the couch, barely watching various Christmas movies while they cuddled and had some sexy fun.

Zane lied on his back, with Froy resting on the actor’s chest tracing invisible circles on his pecs before pausing.

“Babe?” Froy asked, looking up at Zane. “Are you growing out your chest hair?”

“What? No…” Zane said, his voice trailing off when he looked down at his pecs. 

The previously smooth muscle mounds had some slight stubble on them, most of the tiny hairs centered around his hard nipples before spreading out across the rest of his pecs. Zane would sometimes let his chest hair grow out for a role that called for it, but now the tiny hairs covered more of his torso than they should’ve. Zane never considered himself as “Hairy”, yet now he seemed to be on the beginning stages of it.

“Oh, um, I guess I forgot to shave…?” Zane muttered as he ran a confused hand over his chest, feeling the slight stubble. “Remind me to shave it off before my photoshoot.”

Froy mock-frowned. “I will,” he said, “but I have to admit that I think you’d look pretty hot with a hairy chest.”

Zane chuckled. “I doubt it.”

The next morning, Zane shaved his chest to make it all nice and smooth. As he shaved, he could’ve sworn that his pecs looked slightly hairier than usual, but he chalked it up to sleepiness.

When he got on set, Zane absent-mindedly scratched at his t-shirt as he listened to the photographer’s brief.

“…you’re on the beach and you’re ready to be a sexy lifeguard,” the photographer said, pointing at a spot on the set for Zane to stand. “Go ahead and take your shirt off and we’ll get some pictures.”

Zane sauntered over to the spot where he was directed and pulled his shirt off, tossing it to the side. He placed both of his hands on his hips and puffed out his muscled chest as he posed.

The photographer frowned and lowered his camera. “Mr. Phillips,” he huffed, “did you not get the brief? You were asked to shave your chest before the shoot.”

The actor jerked back and cocked his eyebrow in confusion. “I did…” he muttered as he looked down at his chest, gasping.

His chest was now officially hairy.

Coarse black hairs covered Zane’s pecs in their entirety, his hard nipples poking out of the dense fur. The hairs even traveled down his torso, covering his stomach and shielding his hard-earned abs from view. The hair even went upwards and started to grow over his shoulders, connecting to some that were starting to sprout on his back.

Zane looked like he hadn’t shaved his chest this morning, let alone this year.

“What the hell…?” Zane muttered under his breath as he ran a disbelieving hand through the thick fur on his chest. He then blushed when he spotted the other people on set watching him. “I, uh, I gotta go!”

Zane sprinted off the set, barely having time to snatch his shirt to cover his hairy chest from view.

A few hours later, when Froy got home, he could hear Zane’s annoyed grunts from their upstairs bathroom. “Zane?” he called up. “Everything okay?”

“Son of a bitch!” Zane’s annoyed voice roared out, echoing throughout the halls.

Froy rushed upstairs and burst into the bathroom, standing back at what he witnessed.

Zane stood in front of the sink, running an electric razor over his chest frantically. The razor left smooth tracks in the thick fur that covered his muscled torso, causing the black hairs to fall to the floor at the stud’s feet. There were clumps of hair all over the floor, as if Zane had shaved numerous cats and dogs, not just his chest. And it wasn’t just Zane’s chest that was hairy. The dark hairs covered his thick arms and legs, making him look all fuzzy. His stubble had grown in too, covering his square jaw as a beard started to form. The actor was nude, allowing his boyfriend to see his larger bush and his fuzzy ass cheeks.

The actor noticed his boyfriend in the doorway and held his arms out to show off his body. “Babe!” he panicked. “Something’s happening to me!”

Froy’s eyes widened as he witnessed his boyfriend’s shaved chest begin to sprout black hairs that thickened in a snap, leaving his chest looking all hairy and fuzzy in a matter of seconds.

“Damn it!” Zane yelled as he stomped his foot in frustration. “No matter what I do, the hair just keeps growing back!” He ran his hands over his fuzzy pecs to emphasize his point, his cock slightly twitching over the odd sensation. “What am I supposed to do?!” He knew that even if he wore a shirt, the hairs would curl over the collar; and his new beard was also concerning. It was still trimmed and manageable, but he feared that it wouldn’t stay like that of long given how quickly his chest hair had grown in.

Froy walked up to his boyfriend and placed a reassuring hand on his hairy shoulder. “Don’t worry, Babe,” he tried to coo, “it doesn’t look bad.” He wanted to be a good boyfriend and support Zane through this hard time, although deep down he thought that his boyfriend looked incredibly sexy with such a hairy, manly body.

Zane tensed up at the sensation of his boyfriend’s fingers running through his now ample body hair. He frowned as he looked down at his hairy form. “B-but,” he whined, knowing that a lot of his parts and photoshoots called him to be freshly shaven so as to play on his boy-next-door charm, “…you really don’t mind this?” He gestured at his fuzzy pectorals. The hair was so prominent on his chest that he could barely see any of his muscle contour lines; the only parts that weren’t covered by the thick hair were his pink nipples.

Froy chuckled. “Of course I don’t mind,” he said, running his fingers through the thick fur on his boyfriend’s plump pecs, loving how the hairy stud tensed up at the feeling. “And who cares what others think? You look really hot with all of this sexy man fur. Fuck those cute guy roles. You look ready for the sexy man ones now.”

Zane’s heart raced faster in his hairy chest and his cock was throbbing as his boyfriend played with his chest hair, the feeling of another man’s fingers playing with making the hairs feel as they were all live wires each directly connected to his aching cock. They all made his chest insanely sensitive, and the more his boyfriend petted him, the more turned on he felt.

“Ughh!” Zane grunted as he came, his cock shooting its load up in the air, his cum landing on his hairy pecs.

Neither of them knew what was behind all of this, but Froy couldn’t bring himself to really care too much. He leaned in closer to his hot, hairy boyfriend, eager to play with his hairy chest again.
