“I’m telling you, Dude,” Justin Howells vented to his workout bud as the both of them ran on the treadmills for cardio day, “his staring is getting to the point where I’m thinking about talking to the owner.”
Justin was annoyed about how when he’d walked into the locker room because he’d forgotten his reusable water bottle, he’d spotted Dave near his stuff. It wasn’t that Dave was a bad guy or anything. The 40ish year old man had been a competitive bodybuilder back in his prime, but after years of no longer competing, he’d grown a sizable muscle gut that gave him more of a bearish appearance— and he’d made it clear that he found the fitness influencer very attractive.
Justin carried on, not only pissed that he’d been under the impression that he’d caught Dave trying to mess with his stuff (he didn’t have any proof unfortunately), but that the ex-bodybuilder was across the gym at the barbells, not even trying to hide the fact that he was blatantly staring at Justin as he ran.
His friend, Mike, just grunted, too focused on his run than anything.
Justin went on though, mainly so that he could clear his head of all the rage he was feeling. “And the fuckin’ weirdo tries to play it off all cool,” he huffed, feeling his meaty pecs bouncing as he continued to run shirtless. “I tried to confront him, but he shoved my water bottle at me, as if he’d known that I’d go back for it.”
“…yeah, isn’t that something…” Mike panted.
Justin rolled his eyes as he grabbed his water bottle, unscrewing the top as he ran so that he could keep his heart rate up. “No lying, man, next time that roidhead messes with me…” he trailed off and took a sip from his water bottle, the cool liquid sending an odd tingling sensation throughout the stud. He ignored it and swallowed, his mouth feeling like he’d just licked a D battery.
He noticed Dave’s smile growing larger.
“Next time, what?” Mike teased.
Justin cleared his throat and grunted. “I’m gonna…” he coughed and felt his mouth twitch and his tongue seemingly move on its own, “…suck his cock.”
He paled at the words that left his mouth, having had absolutely zero intention of saying anything even remotely close to that. He’d wanted to say that he’d kick his ass.
Mike flinched and cocked his eyebrow. “Huh?” he asked, slowing down the smallest bit.
Justin Howells shook his head and cleared his throat again, even rubbing at it with a muscled hand. “Um,” he stammered, “I said that I was gonna… suck his big cock so hard until he shoots his fat load down my throat!”
The stud nearly fell off the treadmill in shock and horror. Not only had his mouth seemingly forced those strange words out by itself, but he even shouted it out loud, garnering the attention of a couple of other gym goers who gave him weirded out looks.
“Keep it down!” Mike hissed. “You can’t be joking like that so loudly. People are gonna think you and Dave are some kinda thing.”
Justin struggled to regain his footing, his heart racing in his bare chest. He locked eyes with Dave, who was red in the face as he tried to stifle a laugh. However, the second their eyes met, Justin winced internally as he felt a stirring in his cock.
Dave gave the mortified stud a knowing wink as he performed bicep curls, his massive, hairy muscles bulging with power. He then stood up and began to waddle back towards the locker room, his broad back swaying to and fro.
At the sight of such masculine power, Justin’s cock started to plump up. “Wh-what the fuck… is wrong with my slutty body?” he hissed to himself. He frantically looked around the gym, wanting to wail out as he noticed that the stirring in his loins calmed down whenever he looked at anyone else in the gym, but the second his eyes landed on the older bodybuilder, his cock twitched excitedly and he felt himself flex his asscheeks.
“Justin, you okay?” Mike asked as he looked at the other man’s pale face.
Justin turned to his friend, desperately wanting to tell him that something was horribly wrong— that he couldn’t control his words and that he was getting hard just by looking at Dave. Unfortunately, when Justin opened up his mouth, his mortified ears heard himself say, “I’ll be even better as soon as that muscle daddy fucks my tight hole.”
He didn’t wait for a confused response from Mike. Instead, Justin hopped off the treadmill and stomped his way over towards Dave, his hard cock tenting out the front of his shorts. He knew that something was wrong and based on the knowing look that’d been on Dave’s gruff, handsome, chiseled, stubble-covered face, Dave knew what it was. He rushed into the locker room and stopped right in front of the older bodybuilder and tried to lean over him in a threatening way, but his his eyes hungrily taking in the sight of the older man’s hairy pecs barely covered by his tank top ruined it.
Dave just smirked back at the red-faced man. “Can I help you, Bud?” he asked in his baritone-filled voice.
At the sound of the deep, manly bass emanating from the bodybuilder’s plump form, Justin felt his cock twitch and start to leak pre-cum. “Your sexy ass better tell me what you did to me,” he hissed, trying to keep his voice down and wincing when he’d outwardly referred to the man as ‘sexy’.
Dave tried to look innocent, but the chuckle that escaped his full lips gave him away. “What do you mean?” he asked. “And you really find me sexy?”
Justin wanted so desperately to lash out at the older man, to demand that he fix whatever the hell was happening to him. His body, however, had other plans.
“You better shove that thick cock up my ass right now!” he barked, his eyes widening at the gay words that left his lips. Straining, he tried again, even clenching his jaw as he struggled to control his own words. “Wh-what… what the fuck d-did… did you do… me… Do me, Daddy!” He stomped his foot in frustration.
“Yeah, maybe later,” Dave winked, making the other man shudder. “First, I’m gonna let you suffer for a bit— I’ve always heard every time you’d talked shit about me in the gym. Well now, I think you’ll find it hard to say anything negative about me at all from now on.”
Justin paled at what Dave had admitted. He had no idea how, but somehow the muscle gut-having bodybuilder had cursed him, forcing him to constantly vocalize his need for the man’s cock, making him sound like some perpetually horny slut. He imagined himself at work or even the grocery store, unable to say anything besides how badly he wanted a man’s huge, veiny cock in his mouth or ass. Worse was that he couldn’t take his eyes off of Dave’s hairy muscles, his own cock painfully hard now.
“You gotta fix this, Daddy!” he begged, even bringing his hands in front of himself. “Please, fuck me in the mouth and let me swallow your cum.” He coughed and tried again. “Let me be your little muscleslut! N-no, fuck my tight hole… lemme suck those muscletits…” He trailed off, starting to feel hopeless.
Dave stood up and started to head out of the locker room. “I’ll fuck you after my workout,” he promised. “In the meantime, why don’t you go out on the floor and finish what you were doing.”
Justin’s heart raced, but he found his legs moving on their own accord as he strutted back out onto the gym floor.
Mike found him and hurried over. “You alright?” he asked, concerned for his friend. “You rushed off so quickly, I thought you’d gotten sick.”
Justin could feel it bubbling up in his throat. He pleaded with himself to stay quiet, but his mouth started to move all without his say so.
“I’m great, Stud,” he chirped. “I just had to admire Dave’s huge, sexy muscles. They’re so big and manly, especially his massive cock. After my workout I’m gonna let him wreck my tight hole, and then I’m gonna suck him off and ask him to tug on my nips…” The words just kept pouring out of the humiliated stud, and Dave couldn’t help but smirk as he overheard.
You woke up and sat up in your bed, hearing the mattress squeak more than usual. Cocking your eyebrow, you hopped out and hurried over to your bathroom. As you ran, you felt a cumbersome weight whenever you lifted your legs and an unknown bouncing sensation coming from behind you. When you entered your bathroom and flipped on the light, you gasped at your new reflection.
Standing in the mirror before you was the hottest muscle bear you’d ever laid your eyes on. He had thick pecs that were capped with large nipples that stood at attention. Biceps bulged and rested on large lats. Thighs were thick and pressed together, supporting the weight of the massive bubblebutt that was attached to the backside. Plus, the reflection displayed a large, nine-inch cock that dangled wildly with every movement. Best of all was that every large muscle was covered in sexy body hair.
It took you a few moments to register that the reflection in the mirror really was your own. Whenever you moved, the reflection followed suit. You flexed both of your now massive, hairy biceps, grinning widely when the man in the mirror did so too.
“Holy crap!” you exclaimed, feeling so turned on by your deeper voice. You had no idea how you’d managed to get your dream body, but you figured that it was best not to question fate. You happily got ready for work, finding that your clothes had even managed to change as well to fit over your new physique. You opted for the usual button-down shirt and khakis that you wore everyday to the office, however, this time you were pleased to see that your bulk strained the fabric to bursting. Your pecs stressed the buttons of your shirt to the limit and your nipples poked noticeably against the fabric. Your large cock was clearly outlined in your pants and your bubblebutt pressed against the back so much that you wondered if it’d rip to shreds the moment you took a step.
Even when you drove to work, you were giddy with the fact that your massive biceps kept brushing up against your plump pecs the entire drive, making you rock hard.
When you got to work, everybody acted as if you’ve always been a sexy, hairy musclestud. You puff out your chest with pride and strut around the office with your head held high. When it comes time for your big presentation, you enter into the conference room that has all of the higher ups, including your immediate supervisors.
You set up your slide show and stand in front of the board room, and begin to go over your topic, loving having all eyes on you. Again, you puff out your chest with pride, loving how one of the board member’s eyes widened with want at the sight of your hard nipples creating nubs on your shirt.
“…as you can see by the data presented,” you continued, using a laser pointer to direct attention to a graph, “we can clearly indicate that I have the biggest muscletits in this damn office.” You bounced both of your massive pecs, your eyes widening with shock at the words that left your mouth.
One of the board members leaned onto the conference table, cocking his eyebrow at you. “What was that?” he asked in a low voice.
You could feel blush forming on your bearded face and you wanted to walk out of the room to compose yourself. However, your new body apparently had other ideas as you felt your hands grab at your shirt, ripping it open to expose your hairy chest. “I said that I have the biggest muscletits in this office!” you bellowed loudly. To punctuate your obscure point, you reached up and gripped both of your larger nipples and gave them a rough tug, making your cock twitch to life. As if you were witnessing a movie, you saw and heard everything you were doing, but were unable to control any of it.
A few of the board members left the room, weirded out expressions written over their faces, however a few of them (all men) remained, displaying hunger and lust.
You felt yourself toss your shirt to the floor as you started flexing, licking your larger biceps seductively in front of your bosses. You pleaded with yourself to stop as your fingers began to fumble with the button on your pants. However those pleas were useless as you smiled and dropped your khakis to the floor, exposing your widened thighs and large bulge to the room.
“Have you ever seen a bod this sexy?” you asked the men in the room, cringing at the cocky words that you were saying. You even wiggled your hips and made your bulge in your jockstrap bounce, continuing to show off.
You were screaming internally as you felt yourself turn around, slowly bending forward to show off your bubblebutt to the small group of higher ups. Both of your beefy hands slapped down onto your larger cheeks and you wanted to run and hide when you felt them part as you flashed your tight hole to your bosses.
The men cheered and some even clapped at your impromptu show.
“Hmm, looks like it still kills inhibitions,” one of them muttered to the other.
The one to his right nodded. “Yeah, but you can’t deny that they give subjects such a fuckin’ sexy body. I say it’s worth it.”
“Yeah, we’ll be able to market this as some sort of himbo pill: big muscles, zero brains.”
You began to panic at what you heard. Somehow, you’d been a guinea pig for your bosses, testing out some new supplement that had given you your dream body, but had turned you into a major muscleslut at the same time. You cringed at the thought of yourself showing off constantly in public: flashing your hole at the grocery store, playing with your bubblebutt at the movies, tugging on your large nipples at the coffee shop. No matter what, your new body would be on display and you’d be showing off how sexy you thought it was all the time.
“Ughh!” you grunted as you came in front of the men, a large wet spot forming on your jockstrap. As soon as you caught your breath, you felt yourself drop onto all fours and wag your massive cheeks at the men. “Who wants a turn?”
One of them stood up, followed by another, and then another, and soon a line was forming…
Not feeling well tho yesterday and tdy
