"There's so many of those muscled up himbos showing off their large cocks online; but I have a larger following because guys are really interested in the muscle stud with a microdick."

Brad Rowe studied himself in the mirror one final time, running his eyes up and down his impeccable form that was tanned and contest ready.

“Ready to kill it out there?” one of his friendlier competitors, Alan, asked him. The other bodybuilder was massive, clad in just a red poser that popped out noticeably against his tanned skin. His muscles were rippling and looked like he’d spent incredible amounts of time in the gym in order to grow them to their incredible size.

Brad ran a nervous eye over Alan, suddenly feeling inadequate next to the other bodybuilder. Sure Brad was solid with hard-earned muscle, but he looked much smaller when he stood next to Alan.

“What?” Alan asked him, picking up on his friend’s nerves.

Brad shook his head and chuckled a little, trying to get over his envy. “It’s just, shit, you look so fuckin’ massive!” he laughed and then gestured at himself. “I think I can only try for second now. Kinda makes me wish I had a bigger body.” He tried to laugh at the end of his statement, but his jealousy was clearly evident in his expression.

Alan chewed on his lower lip for a second before perking up. “Gimme a sec,” he bellowed and waddled off.  It didn’t take long for him to return, handing Brad a little cup of water that looked like some Alka-Seltzer had been dropped into it.

“What’s this?” Brad asked, cocking his eyebrow at the offered drink.

Alan smirked. “It’s something some guys use,” he smiled. “It’ll make your body look HUGE.”

“Kinda late…” Brad mumbled, but wanting to be nice to his buddy, chugged down the drink in under a couple of seconds. The bubbles tickled his throat as it went down and the extreme carbonation made him a little lightheaded. He let out a loud burp.

The announcer shouted out that it was time for the competitors to line up to head out on stage.

“See ya out there!” Alan said as he waddled over towards the stage.

Brad took a step forward, but the dizziness in his head intensified. He felt like he was about to topple over and had to steady himself against the wall in order to catch his breath.

“Damn, what the hell?” he grunted as he tried to take a deep breath.

He blinked the stars out of his vision and let out another burp, the gas from the fizzy drink building up in his gut. His sight returned and his eyes went wide when he saw his muscles actually starting to grow right in front of his eyes.

The bodybuilder held out both of his jacked arms in front of him, smiling widely in disbelief as he saw them grow in size, appearing to get larger and larger with each passing second. Even his chest pushed out, his pecs pushing farther away from him and jutting out far enough to block his view of his lower body. His heart raced in his now-enormous chest and Brad couldn’t help the swell of pride he felt as he watched his muscles pump up right before his eyes as if he were a balloon being inflated. The drink that Alan had given him had actually worked!

“I can’t believe it worked— what the fuck?!” Brad squeaked, going deathly white when he heard the chipmunk-sounding voice that escaped from his mouth. It was so high-pitched that it sounded as if the muscle man had been huffing on helium.

He reached up to rub at his throat, his head hurting as if felt like he had to focus all of his attention just to maneuver one massive limb. Once his hand was in front of his face, he yelped when he noticed that his palms were giant too, looking as if they were now the size of a workout plate.

The panicking bodybuilder shifted his line of sight back towards the mirror that he’d been standing in front of earlier, gasping at what he saw.

“What happened to me?!” he squeaked in his comical voice as he stared at his new body. His muscles were their same size; they hadn’t grown a single inch. Instead, the bodybuilder stared in horror at his head which had shrank down to the size of a plum.

He looked ridiculous with such a tiny head attached to his massive bodybuilder frame, throwing his proportions all out of sync. It made his body look enormous by comparison, Brad reddening when he realized what Alan had done to him.

“That son of a bitch!” he growled in his chipmunk voice. He tried to stomp over to the stage where everyone else was, but his body felt so heavy and giant that it was hard just to move. He had to focus all of his attention whenever he picked up a muscled leg and stepped forward, careful not to topple over.

“Brad Rowe!” one of the workers called out. “You’re about to be called up on stage! Are you ready?” Footsteps sounded out and one of the employees walked back, dropping his clipboard in shock when he saw Brad and his tiny head.

“You have to help me!” Brad shouted, cupping his hands in front of his entire head to amplify his small voice. “Call a doctor!”

The employee ran disbelieving eyes up and down Brad’s form. “Whoa, Dude,” he mused. “You’re massive!”

Brad wanted to argue, but looked back into the mirror again. His body looked totally giant when his tiny head was taken into consideration. His muscles were massive, and with a plum-sized head, they’d only look all the more bigger.

“A-are you ready to go onstage?” the employee repeated.

All of the fear drained out of Brad and he threw both of his giant arms up in the air, performing a double biceps pose. His small head nearly disappeared behind all the flexed muscle. “Yeah!” he squeaked. “…I just need some help getting to the stage.”

Bodybuilder Brad Rowe relaxed by the pool, soaking in the sun as he lied back on the chair. He’d been given a fancy room at the hotel where the bodybuilding competition was set to take place, and it included full use of the pool, which the hunk took full advantage of.

Brad had just finished his work out for the day and had thought that relaxing by the water was the perfect way to unwind. The pool area was surprisingly empty, so the muscle man enjoyed the silence and the calming warmth that greeted him. Since he was expected to show off his muscled body the next day, the bodybuilder had brought some sunscreen with him to avoid getting burned.

His new assistant had given it to him. It was supposed to be some fancy sunscreen from Europe or wherever. He couldn’t read the language that was written on the blue bottle, but there was a cartoonish picture of a bear on the front that was flashing a thumb’s up.

The bodybuilder squirted some of the sunscreen into his palms, lathering up his large muscles. It smelt a little bit like musk, making him scrunch up his nose, but his assistant had sworn by it, saying that it would quote: “Change his life”. How sunscreen could do that, Brad had no clue. However, he didn’t want to get any points deducted from the competition over something as stupid as a sunburn, so he continued to smear the smelly substance all over his muscles.

The musky smell settled into the air around Brad, and he even started to get used to it. The muscle man closed his eyes as he relaxed underneath the hot sun, feeling little beads of sweat forming on his forehead. In fact, the rest of his body started to feel all the more sweaty and grimy, making him grimace.

There was a slight itching on his chest, and the bodybuilder scratched at it, his eyes springing open at what he felt.

“What the…?” Brad Rowe trailed off as he looked down at his chest, marveling at the sprinkling of dark hairs that were across his bulging pecs. Even before he’d started bodybuilding, Brad wasn’t a hairy man, so the hairs that had somehow spouted out of nowhere was a shock to see. However, it became an even bigger shock when he saw that they were growing at a rapid rate and spreading across the rest of his limbs.

Brad shot out of his seat in disbelief, unable to comprehend how his body hair could just grow out of nowhere like it was now. As soon as he was on his feet, the bodybuilder’s stomach fell as he felt an unfamiliar jiggle. 

“What the fuck!” he cried out in shock as he watched as his chiseled abs, from underneath a dense forest of hair, start to disappear. His six pack gradually turned into a four pack, then two, and then finally nothing. Then even that started to bulge outward as his hairy gut inflated. He grabbed at it in shock, noting how he could feel the hard muscle underneath it, letting him know that it was more akin to a roidgut than just fat.

Panicking, Brad Rowe looked around the pool for someone who could potentially help him. The musky scent of the lotion increased, and as the inflating, hairy bodybuilder took a step, he gasped at how heavy his footsteps felt. He saw that the rest of his body was starting to puff out like his growing gut. 

His legs packed on more meat, his thighs growing even more closer together to support the weight of his jiggling bubblebutt which rounded and jutted out from his backside. His muscled arms lost definition as a thick layer of fat grew over them, which were covered by thick hair. His pecs inflated some more and rested on the large gut that jutted out in front of him. All the while, that musky stench wafted off of the inflating muscle man in waves.

By the time he was done growing, the muscled man stood in shock, staring at his beefy, hairy body in horror. He had no clue what had just happened to him. He’d been cut and shredded one second, and then the next he had packed on weight like it was an extreme offseason and had grown crazy amounts of body hair. His hairy gut was so big that it even obscured the sight of his speedos, making it look like he wasn’t even wearing anything at the pool.

And the musky smell that wafted off of him was insanely strong, making him scrunch up his nose in disgust.

“There you are, Brad!” his scrawny assistant called out as he ran over to him. “Your manager called and said that we have to do your photoshoot now. So let’s get to your room so you can change.”

Brad Rowe couldn’t believe what was happening. There was no way he could take his competition photos in his inflated, hairy body. He held his larger arms out to show off his new bearish form. “B-but!” he stuttered.

His assistant mock-frowned as he fanned at the air in front of his nose. “Phew!” he teased. “Maybe we should get you in the shower first, Big Guy.”

Brad wanted to argue, to say that something horrible had happened to him, but the second his smaller assistant grabbed him by the hand, he lost his words.

The inflated bodybuilder waddled behind the smaller man as they entered the hotel. Blush formed on his face as he realized that he was parading his new beefy form in just tiny little speedos, the backs of which had wedged between his larger ass cheeks. His hairy gut jutted out in front of him, having a little bounce to it with every movement. Worst was the disgusted and sometimes lustful stares he received from the other men in the hotel lobby as they sniffed the air around him, taking in the overpowering musky smell that stuck to him.

Brad struggled to comprehend what had just happened to him, too freaked out over his new body to read the sign that he and his assistant passed which read: MUSCLEBEAR COMPETITION!

“…thank you for the pointers, Mr. Rowe,” the smaller guy, Chuck, said with a big smile on his face.

Brad grinned back and nodded, slapping a beefy hand onto the tiny’s man’s shoulder, completely engulfing it. “Of course,” he said. “I’m always happy to help guys pack on muscle. We can get you to this size soon.” For emphasis, the bodybuilder brought both of his arms in front of his chiseled chest and flexed, his pecs inflating with power. 

Brad had been approached by Chuck in the gym who wanted to ask for some workout tips, stating that he was a major source of fitness inspiration for the guy. Brad was honored and rather enjoyed it when he could interact with his fans, so he was all too happy to give the little guy a pointer or two on how to pack on muscle. Plus, he could tell by the longing stare in Chuck’s eyes that the smaller guy found him attractive, hence he figured he could be nice and flex for him.

But Brad’s generous attitude was immediately halted when he felt a cool gust of air brush over him, discovering that he could’t move out of his flexed position. He strained his massive muscles and tried with all of his might to bring his arms down and stop puffing out his pecs, but all to no avail. 

Brad started to panic when he couldn’t even open up his mouth or make a noise— he was completely frozen in place like a living statue.

“There we go,” Chuck cheered as he clapped his hands together excitedly. “I knew that there’d be no way you could resist striking a pose, and I knew that’d be the perfect position to keep you in.”

Brad couldn’t even move his eyes and he screamed internally, feeling so utterly weak and powerless as he was stuck like a stone. He wasn’t even sure if his heart was picking up speed in his panic nor could he even feel himself breathe. All he was capable of was looking out forwards while maintaining his pose.

Chuck walked circles around the helpless muscle man. “I wasn’t lying when I said that you were a source of motivation though,” he said as he looked over the wide expanse of the bodybuilder’s form. “But not so much for me, since I’m not interested in bulking up. But my clients have raved about how they would love an up close and personal inspection so that they could feel motivated to work out.”

Brad could hear what sounded like numerous footsteps approaching down the hallway, making him start to panic even further. Had he been capable, he would’ve been begging for help or trying to make a bet in order to get released. He couldn’t be stuck performing a pseudo most muscular pose for the rest of his life!

“I’m not heartless though,” Chuck mocked. “In fact, I came up with a way both parties can enjoy themselves.” He gently caressed the crazy width of Brad’s broad back.

The simple touch of another man’s hand on his frozen skin lit up fires of lust inside of Brad. Had he been able to, Brad would’ve moaned out loud at the touch and his cock would’ve been rock hard. He couldn’t see it, but he could feel a pressure growing deep inside of him as if he were getting close to orgasm.

“Nice right?” Chuck laughed. “Every touch of a man will only cause you get more and more turned on; too bad statues can’t cum. Maybe I’ll check back on you in a year or two… if I remember.”

Chuck smirked back at the petrified Brad as he exited the room. Brad wasn’t alone for long though, as three bodybuilders walked inside, each one carrying their gym bags with them. Once they were inside the small room, each one gasped as they took in the sight before them.

“Holy shit!” the one in red exclaimed, rushing forward to examine Brad. “The gym actually installed a Brad Rowe statue!”

Brad bristled inside at being called a statue and he tried to muster any strength he still had to plead with the other men to help him. It was useless though as he was completely immobile and voiceless.

“It’s so lifelike,” the one in blue mused.

The one in yellow stepped forward and placed an admiring hand on Brad’s plump pec.  Again, simply at the feel of another man’s warm, beefy hand on his muscle sent fireworks of pleasure throughout Brad. His mind immediately clouded over and instead of internally begging for help, he begged for the other men to feel up his stone muscles. Their hands were like lightening, sending darts of pleasure all throughout his core.

“Check out his booty,” the one in red laughed, going so far as to cup each muscular cheek in his large hands.

Had he been able to, Brad would’ve black out from the sheer force of cumming. The orgasm that he couldn’t reach was building up inside of him, creating such an impossible pressure that was only growing larger and larger as the three other bodybuilders ran admiring and disbelieving hands over his pecs, his biceps, his thighs. One even grazed his cock and Brad wished more than anything that he could cum.

He felt so turned on by the beefy hands on his vast form and he craved more and more. Had his cock been able to move, it would’ve been at full mast, shooting off load after load as the men felt up his petrified muscles.

The bodybuilder in blue ran over to the door and opened it, poking his head out. “Hey!” he shouted down the hall. “You guys have to come and see this!”

Brad could barely concentrate with the pleasured pressure that kept growing inside of him, making him feel like he was about to explode into a mess of hormones and cum. But the sounds of other muscle men approaching created such a sense of excitement. That was quickly fogged over when one of the men flicked his hard nipple, nearly making him black out as his horniness exploded to unforeseen proportions. 

Brad was at home taking a shower, rinsing off the sweat from his workout. After rinsing his blond hair, the bodybuilder looked around for his body wash, not able to locate his usual brand. For some reason, there was an unknown pink bottle in the shower with him. Shrugging his massive shoulders, he figured that he must’ve forgotten purchasing the new brand when he’d last gone to the store. 

He squirted some of the pink goop onto his washcloth, not thinking twice when there was a slight shimmer to it.

The body wash smelt of bubblegum and when he lathered it up against his smooth, muscled body, it tingled in a way that made him rock hard.

“Oh fuck,” the bodybuilder moaned as he rubbed the tingling suds all over his massive chest, his head rolling back when his beefy hands ran over his hardening nipples. 

He tensed up as soon as the hot shower water rinsed his chest clean, shooting his load all over the tiled wall.

“Damn,” he breathed, shaking his head in wonder over where that orgasm had come from. Chucking to himself, Brad finished up his shower and turned off the water, stepping out and over to the fogged up mirror.

He wiped at the condensation on the mirror to go about his usual hygiene routine. The cooler air outside of the shower felt good on his skin and he could feel his nipples harden again as they cooled off. It was odd to the muscle man since never before had his nipples ever had any sort of feeling to them.

Brad didn’t pay attention to them until the mirror cleared up and he gained an uninterrupted view of his chest.

“Shit!” the bodybuilder loudly gasped as his eyes bulged out of his skull, honing in on the large nubs that stood off his chest.

His previously small nipples had grown to the width of silver dollars and they stuck off his chest by at least an inch. They were so thick that they resembled pencil erasures and they still had a slight tingling in them, making the stunned bodybuilder’s cock twitch despite his panic.

“Wh-what happened?” Brad worried, a shaky hand moving upwards to hesitantly poke at one of the enlarged nubs. “OOOhhhh!” As soon as he made contact, his cock went rock hard and his knees buckled at the insane surge of pleasure that washed over him. Brad had to grab a hold of the counter to keep from toppling over as his cock started to leak precum, his huge nips feeling as if they were on fire with need.

Once his head cleared, panic began to fill the bodybuilder as he couldn’t stop staring at his enlarged nipples which would be close to impossible to hide, especially with their exaggerated sensitivity. He thought of going to hospital or calling his manager— anything to figure out how to fix his warped body.

The muscled hunk hurried to his bedroom to get dressed so that he could rush out to find someone who could help him. He unfortunately discovered that getting dressed was difficult with his new additions. When he put on his shorts, his bowling ball sized biceps kept brushing up against his erect nips, making him moan like a bitch in heat and spasm as he came. But his shirt was even worse. He tugged on a red t-shirt, his moan morphing into a heated shriek as he came again, a large wet spot visible on his shorts. Once he stopped, he was left panting to see that his larger nipples looked like a pair of thumbs poking against the cotton, easily visible for any passerby.

Brad took a hesitant step towards the door, the swaying motion from his gait causing the fabric of his shirt to rub up against his nipples, making him shoot another load into his shorts.  “OOooohh!” he moaned, growing red with embarrassment over how uncharacteristically vocal he now was when he came.

Unable to make it three steps before a seismic orgasm overcame him, the bodybuilder tore the shirt away from him, his huge sensitive nipples standing out in the air for all the see as he hurried out of his house.

“Here you go, Sir,” the assistant said as he put on the finishing touches of the spray tan.

“Thank you,” Brad said, admiring the assistant’s work. “You really saved my ass. I have no idea what happened to my usual guy. He just wouldn’t pick up his phone for some reason.” 

It was the day of one of the big bodybuilding competitions, and Brad’s usual guy who spray tanned him to make his muscles pop was nowhere to be found. He was lucky that one of his competitors was friendly enough to recommend the current guy to him, not giving out much information but just telling him that he’d send him his way.

“Don’t thank me yet, Big Guy,” the man said, slapping Brad on his broad back, rather hard.

Brad stiffened, not wanting there to be any handprints on his tan. He quickly turned around and looked in the mirror, confused when he saw what looked like a long, black zipper running down the broad expanse of his wide back. “What the hell is this?” he demanded. “Is this some sort of prank?”

“You’ll see,” the guy mysteriously said as his arm shot out at a rapid speed, yanking on the zipper to pull it downwards, effectively opening it.

Like the air had been punched out of him, Brad felt breathless for a brief moment and then felt as if his center of gravity was disturbed. His eyes widened in horror when he watched himself deflate like a balloon in the mirror, his body losing mass as it crumbled down onto the floor. He wasn’t able to move his body at all, and even if he had been, his back was so wide that there’d be no way he could reach the zipper and close it.

“What are you doing to me?!” he yelled, his voice getting muffled as he head began to deflate and flop over onto itself. The rest of his body collapsed in on itself until he was pile of freshly tanned skin lying on the hotel floor.

“Just wait and see,” the man taunted, stepping forward and grabbed a hold of the deflated Brad. 

Brad was shocked as he watched in the mirror as the man stepped inside the hole created by the zipper. He could feel him squirming around inside of him, fitting inside of his massive body as if it were a glove designed specifically for the unknown guy. He tried to yell, tried to fight back, but it was as if he were completely paralyzed and helpless to do anything at all that wasn’t the man’s will.

“There we are!” he heard his own voice cheerfully announce.

He winced internally as he watched his own body hold its massive, muscled arms out like it was showing itself off. He even did a three-sixty turn in front of the mirror, the man inside of him demonstrating that he had completely control over all of his actions. Apparently that control extended to his voice as well as he tried to cuss him out or even beg for his body back, but was unable to do anything expect watch and feel his own body move beyond his control.

“You know, once the other guys heard that Brad Rowe was competing, a lot of them thought that they’d lose considering how impressive your body is,” the man inside of him made him say out loud. He pulled his poser away from his body to check out his cock. “Really impressive actually.”

Brad mustered all of his inner strength to fight back, but it was useless. He couldn’t do anything with the man inhabiting his body as if he were a suit.

“But,” the man made him say, a devious gleam in his eye, “I doubt you’ll win the competition if you go on stage in front of all those judges and do this…” He saw himself turn around and bend over. Making sure to glance over his broad shoulder, Brad’s heart fell when he felt and saw his body yank down his poser to flash his tight hole to the mirror. “Maybe we’ll even finger ourself? I haven’t decided yet, it depends on how much I enjoy your body. Thanks for it by the way.”

Brad screamed internally, but was silent as the man forced a smile onto his face and made him strut out of the hotel room and towards the convention area where he knew he’d be humiliated in front of the entire crowd.

He passed by a fellow competitor in the hallway and winked at him.

“Hey, why don’t you swing by my room afterwards?” he heard himself ask. “You can feel how powerful my glutes are.”
