“So, you somehow rented out the gym for an entire night? How did you manage this, Parker? I have to say that this would have had to be really expensive, right?” “Uh, no? I know the gym owner, so he made up a story about how the gym needed to close for a couple of days to take care of a few things that needed renovated or something like that. Something about fixing the showers or updating some of the machines. It was a very convincing story I thought. Most, if not all, of the members believed it. I would have believed it too.” “Yeah, I did read that on Tiktok and Bluesky. I don’t get why we would need the entire gym to ourselves though. This makes me incredibly nervous, and I wonder if I can fully trust you. You have tried to trick your friends before.” “You have known me for literally 12 years Vik. Besides, you had to know that the reason why I met you here at the gym was because I am a sports scientist, and I have been working on ways to enhance the gym going experience.” Vikram stares at Parker glassy-eyed and realizes why he is there. “OH! No no no no... no... Parker, I didn’t sign up for this. You know how I feel about those experimental projects you have been working on with Kyson. I have no interest in becoming a guinea pig for you or him.” Parker grabs his arm and nervously giggles as he stops him from trying to move towards one of the gym exits. “Vik...I... uh...well I admit that I have sort of dreamt about you becoming a huge, hunky, Indian hulk on more than one occasion. Besides, don’t you remember how much fun we had spending time together at the beach a few months ago? All the big muscle that passed us by there.” Vik sighs as he relaxes just a bit and is then embraced by Parker. The two men stand there hugging each other for a couple of minutes as Vik then surprisingly leans in to kiss his friend’s lips. Parker caresses his Indian friend’s soft black beard before they finally separate. “See...you know how much we like each other. I just want to turn you into my beautiful musclebound beefcake, Vik. You are already so handsome and... uh...I just have this thought to see you...” “You will have to do it too then Parker. I will be extremely pissed off if you do this to me and don’t reciprocate on yourself. This is your insane plan to turn me into a freak and well...I also have to admit that I have this fantasy of you experimenting on yourself with a growth formula.” Parker laughs and kisses Vikram on the lips again. They walk to the back offices together and go into one of the rooms to continue their conversation. “Are you wearing your workout clothes Vik? Here is what I am wearing.” The scientist takes his button-up shirt off and is wearing a white tank top. He then takes his dress pants off and is wearing black gym shorts. He already has sneakers on and is showing that he is well-toned but isn’t greatly developed. Vik sighs again as he takes his own button-up shirt off and is wearing a blue tank. He slowly takes his jeans off and is wearing matching gym trunks, showing off his skinny legs and torso. He is wearing loafers, which makes Parker giggle. “Well, I guess that was probably smarter to wear than what I have on.” “I wasn’t entirely sure what to wear. This was my best guess considering what I thought would be just a regular gym session. I didn’t know that you were going to test one of your concoctions on me.” “It isn’t a concoction silly.” He pulls four vials out of the desk in the office. Vikram stares at them in jest. “Four? How many of us were you planning on trying this out on Parker?” He laughs as he puts them back in the drawer and pulls out a single unlabeled bottle from the same drawer. “I just wanted to see your reaction to them. Those are actually vials of GH. The gym owner has those in his desk for himself. I put my secret stash in here as well. This bottle is what I have been working on. They are just capsules, but they have stuff in them that nobody will be consuming except us...and possibly a couple lucky growers.” “Pills? Really? That isn’t what I was expecting. I figured you were going to jab me with something. Well at least that is a relief.” “Yeah, the stuff in these capsules is activated once your hormones begin to travel through your system. In other words, you can expect things to happen if you get aroused or amped up by working out.” “Aroused? Well then you need to take the first one then. I will certainly respond once I see you start growing.” The scientist unlocks the cap and plops two of the pills in his hand. He points to one of them and has Vikram take it. He then quickly flips the remaining capsule into his mouth and swallows it before locking the bottle. He remembers to get two small bottles of water out for them. The thin Indian doesn’t put it in his mouth yet. “Open your mouth, Parker.” “Damn, you are paranoid Vik.” He opens up and shows that it isn’t hidden anywhere before closing his mouth. He even opens one of the water bottles to drink it. “Down it goof. I did what you wanted me to.” “Fuck, I feel like I am being used by you, but for some reason I feel like you are confident that this would work if you took it.” Vikram puts the pill in his mouth and swallows it while also guzzling water. He is now leaning against his friend and seems more relaxed now that they have proceeded with this. Parker has his right arm around his back and is holding him against him. “Heh, here I was expecting you to get more worked up, but now you are calming down. I am not sure it will work if you stay this way.” “I am just glad that you are being real with me Parker. Do I have to do something to make you, you know...get beautiful?” Parker lightly punches him in the gut and makes a few ‘hmmphs’ as he lets go of Vikram and starts walking back into the main gym. The Indian follows behind him and grins at him. The scientist then turns around and starts to moan. “Maybe you don’t deserve me if I am beautiful mister...mmm...oh yeah...this stuff is already starting to work...” He points down at his legs as they begin to swell. The muscle fibers quickly thicken as his quads and hamstrings stretch his shorts to their limits. He reaches down to rub on his cock as it also starts to grow. His breathing intensifies as his excitement accelerates, feeling his pecs and arms squeaking as they begin to expand as well. He can see that Vikram is becoming entranced by what is happening to him and fully expects his friend to lose control of his inhibitions at any moment. “Ah Vik...I really had no clue that this would be so incredibly intoxicating. The hormones are flooding my mind and my muscles. MMM...you are entirely responsible for this you know that? I can’t imagine myself ever going back to the way I looked before this started.” Parker grunts in delight as he watches his biceps and triceps swelling bigger and squeezes his forearms with both of his hands, feeling them bulging with power. His pecs are now stretching his tank to the point that there is now a huge gap in between the fabric and each impressive mound. Vikram can feel things stirring within himself, but he is groaning, trying desperately to stay in control of his current self, watching in earnest as his friend continues to hulkout. “OH YEAH BABY! I am becoming a fucking huge alpha beast. I need to turn around to look at myself transforming Vik.” The growing beast turns to stare directly into the mirrors and begins flexing. The pump is enough for his shorts to rip all the way up to his waist as his big cock flops out and stands erect towards the mirror. His huge bubble butt has now freed itself and is making Vikram moan deeply as the Indian tries to keep his own manhood from escaping from his trunks. Parker has now ripped his gym shorts completely off and thrown them onto a nearby bench. His tank top tears in multiple places from the back as he grunts loudly feeling his immense chest do the same from the front. He pulls it off and bounces his huge beefy melons for several seconds, also studying his defined face and running his hands all over his thick manly mounds and his blocky six pack. He can feel himself getting ready to cum. “Vik...baby...I love my muscles so much that I am going to...AHH!” Parker blasts the mirrors with his massive load, showering them numerous times and shouting in pleasure as he lustfully stares back at his Indian friend at the same time, making sure that he is still eyeing him. He finishes unloading and turns back around to walk over to the Indian. “It is your turn mister. Oh...erraagghh...” He grunts as his feet finally emerge from his sneakers. “Ha, I completely forgot I was wearing those. I put on so much mass that these shoes felt like nothing against my feet.” He puts both of his hands on Vikram’s face and rubs on his beard slowly. He can feel his friend trembling from the excitement and nervousness. The hunky white beast then leans in to squeeze his huge pythons along his partner’s sides and picks the Indian up in his arms. “Look at me Vik. Am I beautiful to you now? I look and feel so fucking huge, and I want you to do the same. I crave a big, luscious, olive-skinned beast.” “Err Parker...I can feel it building up so much inside me...I can’t stop it any more...I can only think about...OHH...GROW...ING...” The white beast moans as he feels his friend starting to expand in his arms. Vikram’s lower half rapidly expands as it forces Parker to let go of him as the Indian lands on the floor. His loafers explode off his feet and go flying into the walls. His gym trunks can do very little to contain the big uncut power tool that is now arching its way down Vikram’s massively expanding right quad. He stares into the white beast’s eyes and laughs as he feels the growth moving into his upper body. His loose blue tank is now being filled with thick furry mounds of flesh popping out from every crevice of the Indian’s frame. He can feel his biceps and triceps inflating as he turns his attention to them and can’t believe that they are growing as big as they are. The thick garden hose veins on each arm stretching from his wrists all the way up to his shoulders makes him start leaking on the floor. Parker is now brushing up against Vikram and is rubbing his partner’s thick man meat. “YES VIK! You are becoming the dreamboat I have always wanted to be with. I want you so much.” The olive beast grunts in delight as his trunks finally rip off his mammoth quads and pelvis as he grabs Parker and wraps his huge hairy cannons around him to pull him into his swelling chest. “RRAARR...I knew this would turn me into a dom... I could feel it deep within me. I am going to stretch that hot hole of yours Parker and you won’t want anyone else.” “Oh yeah baby...push that big, beautiful beast inside me. I want you to fill me up hairy daddy.” As he manages to separate the white beast’s huge quads to start sliding his cock inside his partner, Vikram sighs as his blue tank top surrenders to his incredible size, shredding under the weight of his immense man cleavage and his rock hard eight pack. Parker yells in pleasure feeling his friend penetrating him forcefully and reveling in the Indian’s amazing thickness. “I have wanted to top you for years Parker. Mm...” Vikram licks his lips as he feels Parker’s hole hugging his huge 11-inch beast like a glove. It has been one of his goals since the two men started taking things up a notch just a few months prior. They have now moved over to one of the workout benches as the Indian beast flips Parker onto his back, lifts his legs up in the air and sits them on his massive chest, and grunts as he positions himself over top of the white beast and growls as he pushes his thick rod all the way in. “OH, FUCKING YES VIK...” “You are my huge hunky power bottom Parker. I have so much milk in these huge balls of mine for you to consume. I am going to pound you so hard...mmm...then, I want to shower you in my thick load and watch as you smother yourself in my gorgeous body.” The huge hulking olive beast yells as he grips Parker’s thick calves and thrusts in and out of his lover. Feeling his cum flowing into his cock after several minutes of intense fucking and the sweat pouring off both hulks, he pulls out of the white bodybuilder and lets his seed start to coat his partner in waves. “OH FUCK YEAH DADDY! Feed me that load!” “RRAARRHH...MMM...open that beautiful mouth Parker. He wants to be drained properly by a hungry mouth.” Vikram sits him up and shoves his big beautiful uncut furry cock in Parker’s face as it continues to squirt its juicy milk all over him. He slowly opens his lips as it slides down his throat. He shutters in pleasure as he gets very acquainted with it. His thick neck muscles flex as the Indian beast moans staring down at his lover as he begins swallowing his wet goo. “AHH...I am in love with you hunky white beast. I feel like I could cum for days.” Parker pulls his thick snake out to look up at him and smiles. “Well, you know I would gladly play with this gorgeous beast for eternity, Vik.” He lovingly strokes him, making the huge olive hulk grunt in pleasure. He picks Parker up off the bench and locks his lips on his lover’s. The two beasts moan loudly as they massage each other passionately, squeezing their muscles together and giggling in delight. They both are reveling in the intoxicating scent in the air that they have created from their fluids and their musk. “MMM...we smell fucking good daddy. This place has been christened by both of us as the growth gym.” Vikram agrees as Parker caresses his partner’s huge hairy chest and lays his head on the Indian’s massive pec shelf as they stand there together. They both turn their heads at the same time and notice that they have a bystander, who has dropped their gym bag on the floor. “WHAT THA...is that...you Parker? And... WOW...is this your friend Vikram?” “Ah, hello there Gregg. I can’t thank you enough for allowing us to use your establishment here to further develop...my studies...and to...well...I think you see that it has been successful, right?” “Uh...oh yeah guys. You are both looking freaking huge...and mmm...it smells really ripe in here as well.” The older man starts moaning under his breath as he takes in the manly vapors that have permeated the gym floor. He is the gym’s owner, judging by his polo with the gym’s name on it in green and gray letters. He is wearing a pair of jean shorts that show off his nicely toned legs and is wearing sock shoes. The bald, mustachioed, 49-year-old is now running his hands along his chest, as he feels his pecs starting to inflate, his nipples stretching the fabric and making his cock twitch as it begins to form a giant outline along the left side of his shorts. The two beasts are now encouraging his muscles to keep growing. “OH YEAH GREGG! We could both use another beast to come and join us.” “MMM...yeah what Parker said. Hulkout for us big daddy!” “GRR...yeah, I have been hungering to get bigger boys. Make me blow up so I can join your party here.” Gregg grunts in delight as his feet tear through his shoes and his swelling quads start to strain the fabric on his shorts. He especially loves the feeling of his upper body testing the limits of his shirt as he flexes his expanding biceps and grins as he watches them continue to inflate. “MMM...all those supplements were such a fucking waste of time...I could have just waited until now to...AHH...it feels so fucking GOOD. My cock is getting so fat and veiny.” The middle-aged man looks down and sighs as his cock starts ripping its way out of his shorts. It swells even bigger as he feels it twitch and shoot several ropes of cum across the room. The two other hulks moan in delight as they continue to watch Gregg growing. He moans louder as his swelling biceps and triceps make loud stretching noises. The veins pulse and expand to twice their size. He strokes his big tool as they walk over to get an even better look at him. “Yeah, beast man, get huge. Me and the Indian hulk are hungry for some more muscle and milk, right Vik? “You better fucking believe I am ready for more, Parker.” They both get down on their knees and start messing with Gregg’s big cock as he feels his shorts give way, releasing his thick tree trunk-sized quads from their prison as well as his expanding ass, which Vik has taken a liking to. The bald beast looks down at both of them and laughs as his pecs start to rip his polo. The sound of the fabric tearing excites all three of them as they leak profusely. Parker and Vikram take turns slurping on Gregg’s veiny shaft. “OH, FUCK BOYS! Daddy Gregg has some more spunk he can share. There is so much power raging in these muscles too, appreciative of what you have done for them. I can’t think you both enough for this.” Both beasts savor the older man’s thick frothy load as they take turns gulping it down as Gregg marvels at how quickly he is able to destroy his polo with his back and chest. His thick abs heave in delight as he greedily rips his top off and slings it to the side. He starts flexing his huge round biceps and wide chest when Vikram gets up off his knees and starts lovingly punching him in his gut, making him react in delight. Parker also gets up off the floor after finishing his cock meal and looks into Gregg’s eyes, petting the older beast’s thick furry chest, and then moans as he leans down to lock his mouth on the gym owner’s huge left pec. Vikram is now trying to maneuver himself in between Gregg’s massive glutes with his bloated brown cock. Gregg is laughing as he attempts to do so as the three beasts enjoy themselves immensely. Unbeknownst to all three of these hulks, another man has quietly entered the gym from a back entrance and has ventured into Gregg’s office. He quickly put his briefcase down on the floor, along with a gym bag that he brought with him. He can hear them down the hall moaning and groaning with each other and can smell their vapors. It is Kyson, the Spanish-born lab partner of Parker’s, and he is intensely shy. The man unfortunately is unprepared for what he is about to experience. Still wearing the dress clothes that he put on at the beginning of the day, he had just left the lab where he was working on more research for another project he was going to present to Parker in a few days. He is inhaling the intense man scent of each of the beasts, and it is already making him feel a bit excited. “MMM...Parker has done it this time. I had no idea it would be...so...ahh...” He can feel his legs and arms expanding beneath the fabric of his shirt and pants. He goes into one of the other rooms in the back and notices that there are mirrors everywhere in the room, so he gets even more pumped up. He moans watching himself growing as his chest starts swelling as well. The stretching sounds coming from his muscles is making his cock leak profusely as he stares at himself in the mirrors. “Ahh...this is something that I always thought was a pipe dream. Now...mmm...heh...it is really happening...” He can feel his feet getting ready to burst through his dress shoes as his expanding quads start ripping the seams on his pants. He can also feel his triceps doing the same to his white button-up shirt. He greedily puffs his chest out and grins as it starts testing the limits of the front. He reaches down to run his right hand along the thick outline of his Spanish cock and his left along the contours of his growing pecs and sighs. “Mmhmm...yyeess...the amount of testosterone and adrenaline pumping through me is so intoxicating...” Kyson watches his face become enveloped in a reddish-brown layer of fur, which is also making him smile. He can feel his ass and back muscles swelling to the point that they are about to emerge at any second from their confines. Interestingly, he feels like he can control the growth now and is savoring the feelings in his head. He looks down at his shoes as his growing toes start tearing through his shoes. “AHH...I love it so much. I could easily fall in love with myself with all of this...mmm...heh...okay I guess you can be free...” The Spanish-American feels his huge biceps tearing through his sleeves as his glutes shred the back of his pants. His cock is getting extremely hard, as it prepares to rip itself out. He moans as he slowly lifts his arms, hearing more seams ripping along the sides of his shirt as his thickening lats begin to flare outward. His pits are filling to capacity with thick fur, which is quite visible to him in the mirrors. He grunts, flexing his huge biceps as they destroy even more of the sleeves, both arms now entirely exposed. He puts his arms back down to his side as he feels his chest starting to blast the top buttons on his top in the mirrors. “YUM! OH yeah...they are getting so big and beautiful...ahh...I think I have really huge fucking abs too...” His swelling neck and traps are now tearing seams as he looks on and stares intensely as his big, swollen pecs launch even more buttons into the mirrors and are now exposed. His big Spanish cock frees itself as his pants start to fall down his huge lower half. It throbs wildly as he continues to look on at his chest as it heaves, drenched in sweat. He rubs each round furry mound in pleasure while also running his fingers along each one of his big cascading abdominal slabs. “I am so fucking beautiful. MMM...seeing myself hulking out like this makes me want to...” “Want to what, Kyson?” Unknowingly, his beastly business partner has sneaked in behind him to catch the last parts of his transformation. Parker is now slowly wrapping his huge arms around the Spanish beast as he leans in to kiss him on his neck. The other two hulks enter the room a couple of minutes later to join them. Parker tears the rest of Kyson’s shirt off as he finds his Spanish partner’s hole and begins to enter him with his huge pole. The Spanish beast moans in delight as he gets tons of attention from behind. Vikram is now starting to give him attention from the front. “Whoa, you are freaking gorgeous. If I had to pick...well...let me just have some fun.” The huge Indian is now starting to suck on Kyson’s huge pecs as he vigorously strokes the Spaniard’s big cock. Gregg is standing beside them and is massaging everyone’s huge muscles as he gets ready to get off again. Will the chain continue to grow if more guys enter the gym during this time? I have no doubt what the answer would be, do you know?

Tim and Josh had just finished their workout and were changing in the gym locker room. Tim had been working out for months, trying to bulk up and impress Josh, who was always the biggest and strongest guy in the gym. But Josh seemed to barely notice him, always focused on his own workout and his own physique. As Tim approached Josh, his heart was pounding in his chest. He had been rehearsing what he wanted to say for weeks, but now that the moment was here, he was suddenly nervous. "Josh, I need to tell you something," Tim said, his voice barely above a whisper. Josh looked up from his locker, surprised by Tim's sudden seriousness. "What's up, man?" he asked. Tim took a deep breath and said, "I...I have feelings for you, Josh. I've had them for a long time now, and I just couldn't keep them bottled up anymore." Josh's face turned red with shock and confusion. He tried to back away, but Tim was too quick. He lunged at Josh, wrapping his arms around him and pressing his body against Josh's. Josh struggled, but Tim was surprisingly strong. He seemed to have a new power coursing through his body, and it was growing with each passing moment. As Josh tried to pull away, he suddenly felt a strange sensation. He looked down and saw that his legs were merging with Tim's. He tried to scream, but his mouth was pressed against Tim's chest. He could feel his own muscles shrinking as Tim's grew bigger and more defined. Tim's body was now towering over him, twice his original size, with Josh's body parts sticking out of him like a grotesque Siamese twin. Tim reveled in his newfound power, feeling each muscle in his body grow bigger and stronger. He could feel Josh's body parts merging with his own, becoming a permanent part of him. He felt a rush of pleasure as each muscle fiber expanded, filling him with a sense of power and dominance. As Josh disappeared completely into Tim's body, Tim let out a deep sigh of satisfaction. He was now a completely different person, a giant among men, with Josh's body parts as a constant reminder of his newfound power. He flexed his biceps, feeling the power coursing through his veins. Tim felt a rush of energy coursing through his veins. He could feel the power of Josh's muscles, merged with his own, pulsing through his body. Tim had never felt so strong, so powerful, so alive. He reached up and touched his biceps, feeling the hard muscle under his skin. It was a sensation he had never experienced before. As he explored his new body, Tim realized that he had become a completely different person. The body he had been working so hard to build before seemed small and weak compared to the massive, muscular form he now possessed. He flexed his arms, watching the bulging muscles ripple under his skin. He felt a sense of pride and satisfaction, knowing that he had accomplished something that few others could ever hope to achieve. He took a deep breath and tightened his chest muscles, feeling them bulge and contract under his skin. Then, he let them loose, bouncing his pecs up and down. It was a sensation he had never experienced before, the feeling of his muscles moving on their own accord. He laughed in delight, feeling like he was in control of his body in a way he had never been before. As he continued to bounce his pecs, he realized that he was drawing attention from the other guys in the locker room. They were staring at him, some with envy and others with admiration. Tim felt a sense of pride in himself, knowing that he had accomplished something that few others could ever hope to achieve. He bounced his pecs a few more times, enjoying the sensation of his muscles moving under his skin. Then, he relaxed, feeling a sense of satisfaction and contentment. He knew that he was now a different person, someone who could take on the world and win But it wasn't just the size and strength of his muscles that made Tim feel good. It was the sense of power and dominance that came with them. For so long, he had been the small, weak guy that no one paid attention to. But now, he was a giant among men, with the body to match. He knew that he could take on anyone and win, that no one would dare to challenge him. As he stood there, admiring his new body, Tim felt a sense of euphoria wash over him. He was no longer the same person he had been before. He had been reborn as something new, something better.He was no longer the small, weak guy he had been before. He was now a force to be reckoned with, and he knew that no one would ever be able to stand in his way. And he knew that he would never go back to being the small, weak guy he had once been.
