Glad to finally have the first part of this story back up! It’s one I know lots of you enjoyed back in the day. I thought about uploading all three parts of this story together in one post like I’ve been doing with other multi part stories from the past but honestly this story is just too massive. Especially now that I’m updating and extending it. So for that reason I’m keeping it separated into three parts. I’m even considering adding on a bonus epilogue that wasn’t part of the original! But with all that said, enjoy the story! ❤️
Read Part 2 Here! Read Part 3 Here! Read The Epilogue Here!

“No… fucking… way…” Was all Martin could say or think when he recognised the man who’d been working out across from him at the gym.
Recently Martin, a youthful 27 year old, had really been trying to get himself into shape. He’d been working out at home for some time now but after moving to a new town he decided it was finally time to get serious and sign up to one of the local gyms. The one he picked in the end was rather expensive but from what he could tell it was held in very high regard and had everything you’d ever need. More machines and equipment than Martin even knew existed, an amazing sauna, a large indoor swimming pool and more! That in mind he supposed spending the extra money on it would encourage him to go and make the most of it all.
Upon stepping into the gym on his first day as a member, Martin was of course greeted by the sight of hunks, jocks, meatheads and bodybuilders all getting deep into their routines. The aroma of manly sweat mixed with deodorant flooded his senses in a way that had him struggling to keep his dick under control. Getting a front row seat to all these men pumping their juicy muscles as big as humanly possible certainly didn’t help either. He was already having fantasies about worshipping some of these men. Kissing their biceps and massaging their thighs. Imagining how amazing it would feel to press his face between their meaty glutes. The thought alone was enough to make him drool.
Of course Martin tried to stay respectful and not stare, as difficult as that was, while instead opting to get on with his own routine. After all, if he wanted to be like all the hunks he adored, he needed to put in the work. With that things were going smoothly. He pushed through his exercises and was able to build up a good sweat in the process. However there was something that kept distracting him. Across the gym he couldn’t help but notice how a bunch of people had stopped to watch one particular dude as he worked out. Some were even going up and asking for pictures as he was resting while others had politely asked about workout and eating tips. He couldn’t see the man properly from where he was but he could tell the dude was big. Very big. Martin thought that perhaps he was an influencer or something.
Eventually his curiosity ended up getting the better of him. He finished his last set on the machine he was using before wandering his way over towards the man. If the guy was well known online, Martin wondered if it would be someone he recognised. That could be pretty exciting. He’d gotten there just as the man was doing some heavy bench pressing. He wasn’t able to get a good look at first but when the man put the barbell back and sat up, Martin’s eyes went wide with disbelief. No wonder people had been watching him this whole time. It was the Mr Olympia of classic physique! Chris fucking Bumstead!
From that point onwards Martin found it exceptionally hard to focus on his own workout. Always finding himself peeking over his shoulder to sneak glances at the renowned bodybuilding champion. He had to actively stop himself from trying to scan every inch of that titanic body as he watched beads of sweat drip down Chris’ massive frame, dampening the clothes he was wearing. Thoughts of running his tongue along Chris’ glistening muscles after a long session danced through Martin’s mind. Suddenly no other man in the gym existed. All he cared about was that pure adonis of a man. Suddenly Martin was thrown back to all the times he’d found himself laid in bed scrolling through Chris Bumstead’s Instagram while jerking his dick furiously. Now all those lustful feelings were bubbling to the surface ten fold! Martin had to try desperately to hide his painfully hard erection after that living sculpture of a man walked past him at one point, his scent wafting faintly through the air while invading Martin’s nostrils. A perfect blend of woodsy deodorant and fresh musk. Good god. Martin still couldn’t believe that perfect specimen of a man was only 2 years older than him!
Shortly after pulling off his tee to show off the sweat stained tank top underneath, Chris finished up his routine and headed off towards the locker room to change. Noticing this, Martin couldn’t help but stare from behind. Watching that wide muscled back barely contained by that tank. Eyes practically glued to the huge rounded muscle ass stretching the back of those shorts as Chris exited the main gym floor. Almost every part of Martin’s being was telling him to follow the bodybuilder in the hopes that he might get a glance at that glorious physique without a top on in person.
He didn’t wanna seem weird though like he was stalking the guy so he decided it’d be best to finish up another set of exercises first. Admittedly he sort of botched the form due to his excitement but thankfully nobody seemed to notice. With that however Martin swiped up his towel and water bottle before hurrying off the gym’s locker room as inconspicuously as possible.
Before long he found himself casually glancing down each of the aisles to see if he could find the one and only Mr Olympia he’d been drooling over. Unfortunately after checking most of the aisles, he started to believe that perhaps Chris had already finished getting changed and was long gone as there didn’t seem to be any sign of him. He must’ve slipped out somehow when Martin wasn’t looking. Just when he was about to give up, Martin noticed a pile of gym clothes sitting on one of the empty benches. He wasn’t sure why but for some he found himself oddly intrigued by the discarded clothes. Almost like it they were… calling to him? There was no way to explain the feeling. All he knew was that he had to get a closer look at those clothes.
He made his way down the aisle and towards the bench. It was only when he got closer though that he realised who they belonged to. That huge tank top, those massive shorts and the unmistakable giant sneakers next to them with gym socks stuffed inside. He couldn’t believe it! These were the very same gym clothes Chris has just been wearing! The gym bag next to them with the hunks name on it only confirmed what he already knew. Martin couldn’t believe it!
Did he go and take a shower? Or maybe for a swim in the gym’s pool? God just the thought of sneaking a peek at Chris’ naked body under a steaming shower or doing laps in the pool was enough to make Martin want to cream on the spot. But then something odd crossed his mind… Why would Chris leave his clothes out here in the open where anyone could grab them instead of putting them away safely in his locker??
———
A few minutes earlier…
Chris found himself stepping into a rather empty locker room with only a small handful of men getting changed or sitting around. Upon reaching his locker, he found the aisle it was located on was completely desolate. Or so he thought anyway.
He slotted the key in and twisted it before opening the locker and pulling out his hefty gym bag. He turned to place it down on the bench behind when he jumped in shock at the sight of a man who’d seemingly appeared out of nowhere. “Whoa!… Uhh sorry man I didn’t hear ya.” He said politely with a chuckle and that recognisable lisp of his. The strange man didn’t immediately say anything however, just staring and smiling as he ran his eyes up and down Chris’ body. “Ummm can I help you?… if you want a photo or an autograph or something I’d be happy to give you one…” As weirded out as he was now, the bodybuilder remained kind and polite as he shoved his t-shirt into the gym bag.
“Mr Olympia huh?… Incredible. You really are something. ” The man finally spoke in an almost unsettling yet buttery smooth tone. “And as a matter of fact you can help me.”
The more Chris examined him, the more this odd man didn’t look as though he belonged. He was a lean middle aged guy with perfectly styled salt and pepper hair. His face was framed by a well groomed beard that was a chestnut brown flecked with silver besides the hair on his chin that was a snowy white. The man was dressed in a gorgeous navy blue suit that seemed tailored to his body. The flawless jacket hugged a crisp pink shirt underneath that was decorated by a striped blue and indigo tie. A bracelet that matched his suit and shining silver watch adorned his left wrist. A pair of sunglasses hid a pair of dazzling eyes that no doubt matched the rest of his devilishly handsome visage. He was in good shape underneath that suit from what Chris could tell so he must've kept fit but… something about him was just off. You wouldn’t dress this immaculate just to get a workout.
By this point Chris was starting to get a bit creeped out by the whole situation but he kept his cool and played along. After all he was both a body builder and an influencer which meant he always had to put on his best face for the sake of reputation. “Okay? And how is that?” He responded carefully.
Just then the strange man beamed with a large grin. “Well I’m glad you asked! First things first, my name is Mr Wavell and I’ll be your friendly neighbour hood Warlock this fine day.” He claimed as he outstretched a hand towards the hunk in a respectable manner.
Chris was hesitant but he leant a hand to meet Wavell’s, a look of confusion plastered across his face. “Warlock?” He questioned while clasping the other man’s hand and giving it a firm shake. Part of his subconscious was telling him to just brush this guy off and get on with the day. He was clearly a bit of a nutter. Unfortunately he’d had the displeasure of dealing with his fair share of weirdos since becoming rather famous in the body building sphere. But like usual Chris’ kind hearted nature forced him to stay and hear what this strange Mr Wavell dude had to say.
“Oh don’t worry. You’ll understand soon enough big guy.” Wavell replied somewhat ominously as he let Chris’ hand go. “Honestly it’s not often that I experiment on men such as yourself.” He admitted, shamelessly gazing up and down Chris’ godly physique. “Famous men I mean. I play around with jocks, meatheads and bodybuilder’s all the time but never someone as prominent and well known as you. I can see why too. Your body is a true work of art. The very kind that should be carved into stone and worshiped for generations to come. And to have obtained such a physique without the use of any kind of magic is truly magnificent. I’ll have to be sure that whoever owns it next will keep it in peak condition.”
Chris narrowed his eyes in uncertainty. “W-what? What the hell are you talking about? Experiments? Owners? Magic? Look I’m sorry man I don’t know what this is about but it’s all starting to sound really freaking weird.” He chuckled awkwardly while taking a step back from the suited stranger. “I appreciate the… compliments? But I’ve got other things to do today so again if you want a picture or something we can do that but whatever you’re trying to buy or sell, I’m really not interested.” He’d finally reached his limit with all the strange stuff that Wavell was spewing.
Wavell sighed, a deep purple aura surrounding his body as he waved a hand towards the bodybuilder. “Oh you poor thing. Your compliance isn’t really a factor.”
Suddenly the mighty Chris Bumstead found that same purple energy coiling around his body in the blink of an eye and binding him in place like a muscular statue.Understandably Chris was freaking the fuck out. He tried with all his might to move even a single muscle but nothing responded. He was completely frozen in place.
“If it’s any consultation, I actually feel a little bad about this. I took a peek inside your mind and you’re actually a really sweet guy even when you’re not on camera. Most of the time I wouldn’t go out of my way to take from a guy as genuine and kind as you but…” Wavell reached out and placed his firmly against Chris’ enormous sculpted pecs and began to massage the thick muscle. “Mmmm… you’re just too damn gorgeous to resist. Don’t worry though. I’m sure you’ll grow to love what comes next in time. Everyone does eventually.”
Chris wanted to protest with all his might but not even his mouth was permitted to move by the strange energy binding him. It was impossible to scream for help, not that doing so would’ve made a difference. The only things he was able to move were his eyes that were darting around in a frantic manner.
“Well! Time for step two.” Wavell clasped his hands together with a smile. “But which piece will I store you in? Your tank top? Your socks maybe?” Wavell suggested as he inspected the gym wear Chris was wearing.
The body building champion had absolutely no clue what the hell this insane man was talking about and at this point he didn’t wanna know either. All he knew was that he needed to escape somehow. With that Chris scrunched his eyes shut and tried with every ounce of his strength to move one of his arms. A strained grunt rumbled from inside his throat as he fought against the purple energy but the most he could do was a slight bend in his elbow and a twitch of his fingers before he gave out. Despite how minimal the movement was though, Wavell seemed quite surprised.
“Impressive. That’s quite some willpower you’ve got there big man! Then again I suppose you’ve gotta have some serious mental and spiritual strength to maintain a body like that. I commend you but you might as well save your energy. You’re not going anywhere.” The warlock leaned in and kissed Chris on the cheek in an almost mocking fashion before whispering softly into his ear. “Besides, I’ve just figured out exactly what I’m gonna do with you.”
Without another second to spare Wavell crouched down only to grab the waist of Chris’ shorts and yank them down to his ankles, revealing the tight black boxer briefs underneath. “Ohhh wow…” Wavell muttered as he cupped the bodybuilder’s exceptional bulge. “It’s always the quiet and humble ones that are packing the most huh?” He teased while squeezing Chris’ package playfully. “Well I know for a fact that whoever ends up with this is gonna be a happy man.” With that Wavell stood up once again and looked the powerless man in the eyes. He could tell by the way Chris’ eyes were darting from side to side that he was trying his utmost to beg. Unfortunately for him no amount of begging was going to stop what was about to come next.
“Now. Are you ready?” The warlock asked with a growing smirk, one hand still firmly grasping the hunk’s hefty bulge. “I’ll take your silence as a yes.” And with that he sent a shock of magic that filled the fabric of Chris’ underwear, causing it to glow brightly. This in turn caused a rather intense wave of pleasure to ripple through Chris’ body originating from his boxers. His eyes couldn’t help but roll back as the wave of pleasure flowed over his entire frame before moving back towards his underwear again. And then it ripped out again. And again. It was like an ocean tide pulling back and forth. Flowing out across his body and then pulling back towards his now enchanted boxer briefs again. It was only after about 3 or so of these pulses that Chris began to feel himself getting… smaller? Almost as it was with each wave of magic that spread and pulled back into his underwear, part of his own body mass got pulled with it?!?!
The glorious muscular body of Chris Bumstead continued to shrink smaller and smaller as more of his being was converted into pure magical essence that became infused with his boxer briefs. It wasn’t long before he was even smaller than Wavell, a man he’d been towering over mere moments ago. He would’ve been terrified had it not been for the insurmountable euphoria that he was forcibly experiencing through it all. A euphoria so great in fact that he reached multiple orgasms! Jetting hefty load after load of cum that splattered and stained his underwear. It was so intense that he eventually faded from consciousness.
The very second Chris passed out there was a bright light that consumed what was left of his shrinking body and when it dissipated, the renowned body builder was nowhere to be seen. All that was left was his workout gear that fell to the floor in a sweaty heap, including the pair of freshly enchanted boxer briefs that now housed the sleeping soul of Chris Bumstead himself.
Mr Wavell leant down and scooped up the pile of clothes along with the socks and sneakers before placing them all on the nearby bench. Now there was just one final touch that had to be made. He waved a hand over the pile of clothes, placing another perception filter over the, that would make anyone who Wavell deemed unworthy of this gift unable to see or perceive the clothes. For example if by chance a roided out asshole happened upon them first, he would barely take any notice of them. Only those who were worthy of taking up the mantle of the kind and humble Mr Olympia would be able to see them. But with that Wavell decided his work here was done, turning himself invisible once again so he may sit back and simply enjoy the show. Opting to float up and sit atop the lockers and watch until someone received the present he’d left.

As Martin inched closer to the pile of sweaty gym clothes he’d stumbled across, that very same aroma he’d smelt back in the gym wafted over his nose. Yup those were Chris’ clothes alright. No doubt about it. He made sure to look left and right down the aisle to check that nobody was watching before sitting down on the bench beside the seemingly discarded clothes. It already felt as though his heart could explode with the anticipation alone. He just wanted to grab the tank top and press it flat against his face. But what if someone saw him? It was only his first day at this place and he didn’t wanna be labelled the gym weirdo who went around sniffing other dude’s clothes. But that smell… It was just so damn tempting. He checked around one last time before giving into his urges and swiping up the body builder’s tank top.
The next thing he knew Martin had a raging boner straining against his shorts as he held the damp tank top to his face. Unable to stop himself from deeply huffing and inhaling the strong musky scent of an alpha such as Chris Bumstead. Allowing it to overpower all of his senses and sink so deep that everything else faded away. Only him and the sweaty tank pressed against his nose existed in that moment. If there was a heaven, this is how he imagined it.
Slam!
The sound of a nearby locker closing tore Martin’s mind away from the haze with a sudden jolt. Luckily it seemed to have come from a different aisle. His face still went red however, praying that nobody had walked past and seen him. With a sigh he was about to set the tank top back down when something caught his eye. Inside the shorts was a pair of underwear that Chris must’ve been wearing. Already Martin’s mind was going a mile a minute imagining what the pouch of that gorgeous man’s underwear smelt like after a good workout. He just had to know! But he couldn’t risk anyone seeing him. A tank top was one thing but if he was caught sniffing another guy’s underwear in the locker room he’d be seen as a total perv and kicked out for sure.
Part of him thought of doing the right thing and leaving the clothes where they were but the urges of a horny gay man were a powerful thing which in this case Martin just couldn’t bring himself to ignore. So instead he settled on a plan. He scooped up Chris’ gear along with huge socks and sneakers the hunk had been wearing before dashing around the corner and locking himself in a private changing cubicle.
He knew what he was doing was wrong but he just couldn’t help himself! Before long the young and very horny gay man had stripped off his own clothes and begun jerking himself off furiously while digging his nose into the tank top once again. The smell was still so fresh. New sweat that’d only just poured from that Adonis’ body and absorbed into the fabric. It smelt fucking delicious and Martin wished he could savour it forever.
Soon after that his eyes settled on the huge size 13 sneakers. He grabbed one and yanked the white gym sock out from inside before burying his nose in it. It was incredibly damp with sweat and had an even stronger scent than the tank. But that only made it more intoxicating. After a good few minutes, Martin was only able to pull himself away from the sweaty sock to stuff his nose inside the massive sneaker it came from. And somehow that smell was even more pungent! No wonder. It was a heady mix of old sweat from previous workout mixed with the new fresher scent of today, forming an aroma so mind numbingly powerful that Martin could barely control himself. He had to let go of his cock for a moment just so he didn’t cum on the spot.
From there he must’ve spent god knows how long edging himself in that cubicle, trying not to cum or make too much noise. He switched feverishly between deeply inhaling the sneakers and rubbing the socks all over his face. Chris’ scent was so damn addictive. He found himself fantasising about Chris standing in the cubicle with him, imagining that it was actually the dreamy hunk himself who was holding the massive sneakers up to his face and forcing him to sniff it. The mere thought was enough to have him leaking a constant stream of precum.
It took a good long while but eventually Martin decided he’d had his fill of the sweaty socks and sneakers, for now anyway, and decided to get onto the main attraction he’d been saving until last. He glanced over at the shorts with a lustful grin. Without hesitation he dove his hand inside them and fished out the pair of black boxer briefs that were hidden inside. His pervy mind was already racing at the idea of sniffing both the front and back of them. But just as he was about to dig in he noticed something odd.
The pouch. It seemed damp. At first he thought it was just Chris’ ball sweat but it was more than that. It was… sticky? Curiously Martin checked the inside of the boxers and his eyes went wide. There was no way. That couldn’t be what he thought it was right? Pooled inside the pouch and partially absorbed into the fabric was an unmistakable sticky white substance. With his heart now beating out of his chest, Martin dipped a finger inside and scooped some up before sticking it in his mouth. There was no doubt about it.
It was cum.
Martin had just tasted Chris Bumstead’s cum! And it was delicious!!!
A million questions were racing through his mind right now. The biggest ones being: why the hell had that hunk of a man shot a load while at the gym? And even more importantly, why had he left his cum-filled underwear out for just anyone to find?! It didn’t make sense at all. When would Chris have even had time to do that? Not to mention Chris didn’t at all seem like the type to do something like that. Deep down a part of Martin’s brain was telling him this was fishy. Unfortunately that part of his brain was completely drowned out by the rest of his mind that horny beyond imagination right now.
“Oh well… If he’s that careless then I’m sure he won’t mind if I clean up his mess.” Martin muttered to himself while licking his lips.
He gently raised the boxers up to his face, grinning down at the soaked pouch before him. He was already starting to salivate at the sight. Martin always wanted to taste a bodybuilder's load and now he had the best of the best. Top of the line alpha male seed. And so, without another second of hesitation, Martin dove his tongue into the pool of fresh man milk and started licking away. He immediately found himself shivering with delight at the immaculate taste. Sure he’d tasted cum before but it was nothing like this! He could drink gallons of this stuff! Before long he was lapping it up like a feral animal! He had to make sure that he got every last drop of delicious stud cum. And just when you’d think it couldn’t get any better, the flavour was even further enhanced by the taste of Chris’ sweaty balls mixed in.
By the time he’d finished lapping it all up, Martin was a hot mess. He found himself sitting with the underwear draped over his face, sniffing and tasting the delicious groin sweat from it idly. With a belly full of Mr Olympia grade cum, all he could think to do now was wrapping Chris’ damp tank top around his ridiculously hard cock and jacking it until he burst. And that’s exactly what he did, pumping away as he lost himself completely in all the smells and sensations. Edging as much as humanly possible while trying to savour the moment as much as he could. It didn’t even feel real. He thought that at any moment he was gonna wake up back home in his bed after having the best wet dream of his life. And yet he didn’t. This was reality.
Martin was just about ready to shoot his load and glaze Chris’ tank top with it when he was stopped by the perfect idea that suddenly popped to mind.
Next thing you know he’s jumping up off the seat and smiling giddily as he glances at the cubicle mirror. There was just one last thing he had to try before he stuffed these clothes into his gym bag to take home and treasure forever. He had to wear them.
He didn’t waste any time. He began by snatching up the boxer briefs again before stepping into them and pulling them up over his ass. Admittedly they looked more like baggy boxers on him than fitted boxer briefs. They were mainly being held up by the waist band and the tent his dick was making in the front. The feeling of which sent shivers up his spine as the tip of his cock brushed against the dampness where Chris’ load had been. Then after taking a second to appreciate how amazing it felt to wear Chris Bumstead’s underwear, Martin swiftly moved on by grabbing the shorts next. He slid his legs inside and pulled them up before securing them in place by tying the drawstrings tightly. Once again something that would’ve been ordinary gym shorts for a hunk like Chris looked more like huge basketball shorts on Martin. That didn’t make it any less hot though. This was then followed by him slipping the tank top over his head in one smooth motion. It slipped off his shoulders once or twice but he eventually got it to stay in place. At last he was able to bask his upper body in the warm musky aroma of the tank top in the hopes that it would stick to him. After that, all that was left was footwear Chris had left behind.
The huge damp white socks were first. After giving them each one last quick sniff, Martin reached and pulled on each over-sized sock, drenching his feet in Chris Bumstead’s sweat. He couldn’t help rolling his eyes a little in ecstasy at the mere feeling. Once he’d had a chance to enjoy wiggling his toes inside the sweat stained socks, it was time at last for the sneakers. Getting to slip his average sized feet inside those enormous things felt like an orgasm in of itself. He tried his absolute best not to bust as he felt his socked feet suddenly being wrapped in the hot sweaty musk that was trapped inside those pungent sneakers.
And with that his naughty little cosplay was complete.
After all that Martin could only grin cheekily as he looked at himself in the full length mirror. Sure the size difference might’ve made him look like a kid swamped in his dad’s clothes, but he couldn’t deny that it was still hot as fuck. Especially knowing that he was wearing the exact same clothes Chris himself had been wearing less than an hour ago. The adrenaline pumping through his system right now had Martin on cloud nine as he committed every detail of this to memory.
“What’s up? My name’s Chris Bumstead.” He snickered at his reflection while trying his best to imitate Chris’ voice.. “I bet you’re wondering what my secret to looking like a muscle god is. Truth is I just get really horny while working out and bust a nut after my session. Totally helps the gains.” Martin continued half mockingly as he flexed one of his arms, imagining it was Chris showing his mouthwatering biceps. He continued to mutter all sorts of pervy things and imagine it was the real Chris saying them all the while listening to make sure nobody outside the cubicle overheard him. Little did he know that one person in particular had seen and heard everything.
Wavell had watched idly as Martin had crept over to the pile of clothes earlier and swept them up. It’d been a treat getting to see this horny young man goon for around half an hour over the famous bodybuilder’s scent. Honestly Wavell couldn’t blame him one bit. After all he’d given Chris’ clothes a quick sniff as well before leaving them to be claimed and that scent was divine. “Now that he’s wearing them it should start any second now…” Mr Wavell mumbled to himself as he watched Martin curiously. And as if on cue, the black boxer briefs began to emit a soft purple glow. “Yuuup… here we go.”
Martin didn’t seem to take any notice of the glow at first as it was concealed underneath the shorts. He only noticed something strange was going on when the magic glow became bright enough that its light began to seep out of his stolen shorts. “H-hey what!? What the h-hell?!” He was about to pull off the shorts in a panic to see what was going on down there but before he had the chance there was a shooting sensation that flooded his body like a lightning bolt, causing him to seize up a little. “Uuuuuoooaaahhh… What the… fuuuuuuuuck…” Martin groaned without much control. He felt an indescribable mix of pain and pleasure that sparked through every nerve and muscle in his being. His brain struggled to keep up with the sudden overstimulation and couldn’t decide whether it loved or hated the feeling.
He would’ve been more worried about this had it not been for the rising heat in his chest. He could barely comprehend the feeling. It was like… something was building itself up? Martin only realised what was truly happening when he glanced down at himself to see that his once unimpressive chest was now surging forwards with muscle in pulsing waves of growth. He could hardly believe his eyes as he watched himself grow a hefty pair of pecs that began to slowly fill out the front of the stolen tank top. As they expanded he could feel his torso stretching and broadening slightly to accompany his growing chest until they reached the size of massive watermelons! The shock of it all caused Martin to stumble a little before falling onto his hands and knees with the weight of his new meaty muscle tits weighing him down. They looked bizarrely out of place on his small frame but not for much longer…
“What t-the fuck… Is h-happening… to meeeee?!” He just about managed to grunt out while attempting to pull himself back up but to no avail. Not when his back suddenly decided to follow the same example as his chest. After his pecs, the rest of his growing torso upper body kicked into full gear with its fantastical growth. Ridges and contours of hard earned definition began etching themselves onto Martin’s back as it grew huge and wide with newfound muscle! His arms were forced to spread apart some more as his lats flared out like the wings of a true bodybuilder. Before Martin could even comprehend that however, his shoulders ballooned into monstrous cannonballs that only served to widen his upper body further. Even his traps bulged and expanded before his neck thickened into. Suddenly the sweaty tank top wasn’t hanging off him so loosely anymore…
His confused moans echoed not only through his little cubicle but across the entire locker room. And yet nobody seemed to take any notice. Not even as he let out a roar when his arms and hands started to grow. He watched as his fingers stretched longer, each digit thickening as callous’ began to form along his expanding palms. Marks to symbolise years of long hard dedication to the gym. Even more eye-catching however was the sight of Martin’s once average looking arms beginning to hulk out as veins snaked up his inflating forearms while his biceps and triceps swelled to sizes bigger than he ever could have dreamed of. Soon enough his biceps and triceps had bulked up to monstrous sizes with his forearms following suit. Even his hands weren’t safe as they thickened up.
Martin gritted his teeth as he felt what little fat he’d once had around his belly evaporate to make way for a thick and powerful set of abs that cobbled themselves onto his stomach, Martin was given a few seconds of momentary relief to catch his breath. “M-my body!? H-H-How!? I don’t… I…” He stumbled through his words in a panic, not knowing how the hell to even begin articulating his feelings right now. Especially as he glanced up into the mirror, still kneeling on all fours. His build looked like that of a human gorilla with the comical size difference between his gigantic upper body and relatively small lower body in comparison. In fact he doubted he could even stand properly as he was!
It didn’t take long for the transformative heat to return in full force. For as freaked out as he was right now, Martin didn’t know if he should be worried or relieved. Regardless, the intense sensation began to focus itself on his lower half. More specifically his ass first which didn’t waste any time blowing itself up with newfound mass. What was once a fairly average backside ballooned into a massive bubble butt carved from thick muscle that could harden into buns of steel with a single flex. He even let out a long and pleasurable moan as his asshole found itself tightening significantly. Suddenly the stolen shorts and briefs he was wearing looked far less baggy than before, now stretching over his thick bubble ass rather nicely.
Just then his eyes went wide with both fear and a little bit of underlying excitement after feeling where the warm sensation had shifted to next. “Oooh god oooh fuuuck…” he groaned nervously as it focused on none other than his cock and balls. Thankfully, just like the rest of his body, even they started to expand rapidly. His balls grew into a pair of huge cum-filled alpha male that only churned the most premium cum imaginable. Meanwhile his already hard cock engorged into a girthy ten inch anaconda, that didn’t just fill but stretched out the pouch of his stolen underwear perfectly! Feeling this Martin couldn’t help but allow a dumb grin to spread across his face. “Ughhhhfff… I’m huge huhuhuhuh…” He chuckled as the now much larger and obscene tent in his shorts bucked excitedly.
He’d become so distracted by the size of his new manhood and crown jewels that Martin almost didn’t notice his legs starting to get absolutely juiced. It started slow at first with his thighs and calves pulsing with a tiny bit of extra size and definition. It wasn’t long however before a strained growl escaped his clenched mouth as both legs began stretching out longer, bumping him up to a staggering 6’1. Something he’d soon find out when he was eventually able to stand up. But as soon as his legs finished elongating, his quads and hamstrings erupted with an explosion of bulging muscle mass causing another roar to escape his lips. In mere moments he’d been granted the thighs of the century but it wasn’t done there. Moments later Martin found himself cooing in pleasurable discomfort as his calves pumped up to the size of footballs while looking hard as diamond. Finally Martin’s body was starting to look proportionate again but there was one last part of his lower body that needed changing.
Finally his toes started to curl and wriggle inside the hot sneakers. Right now they still felt like clown shoes on him but not for much longer. Martin was just about able to stifle another moan as his feet started expanding, growing longer and meatier by the second. The free space inside Chris’ sneakers swiftly began to fill as even the sweaty white socks started to fit better around his enlarging feet. Growing upwards from size 9 to size 10 then 11 and even 12!? Only stopping when his feet finally fit snugly inside the enormous pungent size 13 sneakers! At last Martin had the exact kind of huge manly feet he’d secretly dreamt of either having or worshipping.
By this point Martin simply looked like a hulking bodybuilder version of himself but that would soon change. All of the distinct features across his body that made Martin unique began to fade only to be replaced with unique qualities of another man. Whether those features be blemishes, body hair, tattoos or even the tone of his skin! The only semblance of his old self left now was his head. Though, judging by the way his face was starting to heat up, that likely wouldn’t be the case for much longer.
It began with his neck bulging a little, his adam’s apple changing and altering his voice in a way that made it drop a couple octaves. That was the least concerning of the right now though as his facial features started to shift. His jaw began to widen as Martin’s once soft chin squared off with a sharp masculinity. His cheekbones rose up slightly, forming an angular structure in tandem with his jaw that was taut and defined. His brows thickened while his eyes took on a newfound mix of softness and intensity. The eyes of a kind beast. His nose broadened slightly as it tapered into a strong bridge. All the while his changing features made sure to reposition themselves as even his head reshaped slightly. As soon as they were all in place, thick stubble broke out across his larger jaw which swiftly grew into well groomed facial hair that framed his new handsome mug perfectly. Even his hair restyled in process while lightening in colour from black to a rich brown.
After all that his mind was spinning like crazy but the good news was that whatever had been spreading through him and changing his body had finally dissipated, leaving him on the floor sweaty and exhausted. He gave himself a moment to gather his strength before pulling himself up off the ground.
He was disoriented to say the least. His new body trembled slightly as he pushed himself up onto his massive new feet that filled out Chris’ large sneakers perfectly now. He stumbled for a moment as he found his balance with all this unfamiliar weight before looking down at his enormous hands. Needless to say he was still in shock over it all. Looking down at himself, Martin no longer saw the lean average build he was used to seeing everyday. Instead stared down in awe at the huge hulking form of a professional bodybuilder. Huge hefty pecs, colossal biceps, hulking thighs. All of which allowed him to perfectly fill out these massive gym clothes. The real shock came however when he finally glanced up to look in the mirror once more…
“Holy fuck!” He shouted with a stunned look on his face. Only it wasn’t his face anymore. Staring back at him was none other than the three time classic Mr Olympia himself! The very man Martin had countless saved pictures of for jerking over. The hunk who’d starred in more than one of his wet dreams over the last few years. There was no mistaking it. His hands shot up towards his new face, inspecting his features to be sure they were real before running his hands through his hair and beard. This sculpted body… This gorgeous face…
“I-I’m… I’m Chris fucking Bumstead!!” He announced, almost not believing his own words as they spilled out in a new unfamiliar voice.
Mr Wavell had witnessed the entire thing go down, invisible as usual. “Mmm… now that was hot.” He hummed to himself as he watched as the new hunk admired his reflection with glee and disbelief. “Maybe I should stick around for a while and see how this plays out.” He shrugged. It was always fun to watch how his subjects adjusted to their new lives and bodies.
