Alec was shredded. His body fat was in the single digits, his muscles were cut like diamonds and if he wanted to go into professional bodybuilding, he probably could.
But he didn’t. He wanted to bulk.
“I don’t understand you man,” his friend Doug said to him one day at the gym, after Alec had listed his woes, “You’ve got this perfect body, you could get all the pussy in the world, and you wanna get fat?”
“I wanna get big,” Alec clarified, “bigger muscles, bigger biceps, bigger pecs.”
“But you already have all those,” Doug bemoaned. Doug had always struggled to stay in shape, whereas his friend seemed to always look like an underwear model. Words like “bulking” and “cutting” were alien to him. And Alec didn’t have the energy to explain.
“Excuse me,” said a voice from behind them, “I couldn’t help but overhear… did someone say they were interested in ‘bulking?’”
The man behind them was enormous. Standing at well over 6 feet with muscles that made him as wide as a tank, he gave his balls a hearty itch under his sweaty shorts and took a giant swig from his portion shake. Some of the brown juice clung to his beard, which was as impossibly thick as the rest of his body.
Alec cleared his throat. “Um… yeah, I’ve been trying to bulk up these last couple of months, but I’m still not taking in enough calories. My metabolism is off the charts.”
The man gave a deep belly laugh, and rubbed the shake from his beard. “I used to be just like you, kid,” he said. “I was so lean, I couldn’t put on any weight. But then I tried these.” He lifted up the protein shake, “and now I gotta work to keep from full on bloating.”
Alec felt a rousing in his shorts. A powerful erotic sensation at the thought of finally putting on some weight, the thought of looking like the man who stood before him. Huge, hairy. Hot.
“What’s in the shake?” Asked Doug.
The man smiled, leaning in and dropping his voice. “Secret stuff. Not FDA approved. And you gotta be careful too. Like I said, too much of it and you start to bloat. Not to mention all the hair.”
“The hair??”
“Oh yeah,” the man said, running a hand through his beard. “You think I had this before I started drinking these? I used to be as hair-less as your friend here—“ he pointed to Alec, who’d always been naturally very smooth, “but since this drink’s supposed to boost your testosterone, I can’t keep up with all the hair I’m growing. See this?” He pointed again to the luscious hair on his face. “I started growing this last week.”
Doug’s jaw dropped. “No.”
“Oh yeah, bud,” the man nodded. “It’s a real nuisance, but like I said: if you wanna put on weight…”
Alec was in a trance. The man had leaned in so close, he could smell whatever he was drinking on his breath. The scent was intoxicating, milky and sweet, yet irresistibly masculine.
“Can I try some?” The words blurted out of his mouth before he could stop them. What a rude thing to ask! Just taking someone else’s protein shake. Even Doug looked at him incredulous. But the man laughed.
“Just a bit,” he said, “JUST so you can see what I’m talking about. I don’t want you getting hooked or anything.” Doug wasn’t sure, but he could have sworn he saw the man wink.
Alec put the orange bottle up to his lips and took a small sip. It tasted even better than it smelled. The drink was so thick, so rich, he felt like he’d eaten a whole meal.
“FUCK,” Alec cried out as something rushed through his body. He needed to pump. Now. He reached for the dumbbell rack and started doing curls, energy angrily surging through his veins. Before he knew it, he’d done seven sets, and was sweating like a pig.
Doug looked at him aghast. “Damn dude,” he said, “that drink must have given you a real energy boost.”
“Something like that,” Alec said. He was looking around for the giant man. He needed another sip. Just one more sip.
“He took off,” Doug said, reading his mind. “Probably for the best. That illegal shit can be scary.”
“Yeah,” Alec said, “scary…”
Alec dreamt of the man that night. He dreamt that they were at the gym, doing drop sets. Every weight he lifted, every rep he did, Alec could feel himself growing bigger and bigger. Just like the man. They’d stop in-between sets to feel up each other’s muscles, rub their beards together, and—
BEEP. BEEP. BEEP.
Alec’s eyes fluttered open. Disappointed (and horny), he forced himself out of bed and lumbered to the bathroom. He switched on the light, and froze in shock.
“Whoa,” Alec said. The man in the mirror was still clearly him. But Alec didn’t have dark hair. Come to think of it, Alec didn’t have that much hair AT ALL. And yet, the man staring back at him had a chest peppered with black scruff, which also sprouted from his face to form a handsome 5 o’clock shadow. His eyebrows were bushier, the hair on his head was thicker, but most importantly…
He was thicker. Alec’s muscles had seemingly grown overnight. He’d lost a little bit of his definition, but he’d more than made up for it in pure, hard mass.
He must have been admiring his reflection for twenty minutes before his phone rang. It was Doug.
“Hey man, wanna meet me at the gym later today?”
Alec was suddenly worried. What would his friend have to say about his new looks? It was obvious that it was the shake. All the man’s predictions had come true: just one sip and Alec was hairier, bigger, and sexier then ever.
But that also meant Doug was right: this stuff is dangerous. If he had changed that much from one sip… what could two sips do? What could an entire bottle do??
The thought terrified him. But it also turned him on. If he ran into the giant man again, would he be able to control himself?
“I can’t believe you actually tried it,” Doug said as they left the locker room. As Alec has suspected, his friend had reacted to his new mass with trepidation. “Who knows what other chemicals they got packed into that stuff.”
“Yeah, but it worked!” Alec said, excited. “Doug, this could be what you always wanted.”
Doug squinted. “What do you mean?”
“I know you’ve always wanted a body like mine. With just a sip or two from this drink, you could have that body tomorrow!”
Doug scoffed and shook his head. “That shake isn’t just giving you a big body; it’s giving you a big head.” Alec laughed, and the two headed out the doors to the parking lot. “Besides,” Doug continued, “it wasn’t your shake to begin with. I couldn’t have any even if I wanted t—“
“Well look who it is.”
It was the man from the day before. Only this time, he had not one, but TWO shakes.
Alec almost fainted with excitement.
“I see you’ve put on some weight,” the man said, pointing to Alec, “and I’m not just talking about bulking.” Alec reached up and felt his facial hair. He’d never felt hair on his face before, and he couldn’t stop touching it. The prickly feeling of the scruff under his skin was so intensely erotic, he thought he might pop a boner right there in the parking lot.
“Listen, dude,” Doug said, “I don’t care what you wanna put in your body, but my friend here isn’t having anymore of your black-market—“
“Is that for me?” Alec was pointing to the second shake. The man smiled down at him. He was still so, so tall.
“If you want it,” the man said, “I figured by the look on your face when you were pumping yesterday that you got a real kick out of it.”
Doug’s jaw dropped. “You’re giving him a whole shake??”
“Of course not,” the man said, “I diluted it down. Like I said, too much of this stuff could bloat you big time.” He turned back to Alec, and gave a very obvious wink, “but I made sure to put more in than a sip.”
He held out the drink and Alec took it with shaking hands. His mind was reeling from the thought of growing big like the man in front of him, of bulking to impossible size, with pecs like tires and arms as thick as bricks. As he threw back his first sip and felt the sweet, milky substance fill his stomach, he fantasized about the two of them worshiping each other’s bodies, entangled in a knot of muscles, scruff, and sweat.
“This is ridiculous,” Doug said, “C’mon Alec, let’s go home.”
But Alec didn’t want to go home. He didn’t want to go anywhere but back inside the gym and pump his muscles to high heaven. The drink was saturating his body with a powerful need to work out. Going home and sitting on the couch was simply impossible.
“I was just about to head in for my workout,” said the man, “if you wanna join me—“
“Yes!” Alec said, without hesitation. He didn’t see the hurt on Doug’s face, and failed to notice his friend march away from them and out into the parking lot. His eyes were locked on the man in front of him. And that’s when he realized… “I never got your name?”
“Blake,” the man replied, “now come on, let’s put that juice to use.”
BEEP BEEP BEEP.
Alec slapped his alarm clock with such force, it cracked open and sputtered out. He wasn’t that strong, he thought, unless…
He rushed to the bathroom, barely squeezing through the door as he switched on the light.
It was true. He was enormous. Easily the size of Blake, with pecs like tires and biceps like bricks. His traps were larger than he ever thought possible, and he could see them out of his peripheral vision whenever he turned his head.
And then, of course, there was the hair. Alec was sporting a full-on lumberjack beard, thick enough to tickle his pecs every time he bent his head down. And the black scruff on his chest had erupted into a forest of hair.
Alec ran a hand down his cleavage. After all, that’s what it was. His pecs had never been this large, and the chasm between them was as thick with hair as the rest of his body. He inhaled and took in his musk, potent from a long night of sweating, tossing and turning, dreaming about Blake.
He picked up his phone, his big meaty fingers struggling to press the digits as he called the number Blake had given him yesterday evening.
The man picked up in two rings. “Alec,” he said with a smugness in his voice, “I thought you’d call. Did you like what you saw when you woke up this morning?”
“Y—yes,” Alec stammered. His attention was split between the phone and feeling the shape of his bulky muscles.
“I bet you’re as big as me by now, judging by how much you drank.” Blake laughed, “how’d you like to be bigger than me?”
“W—what?”
“Meet me at the gym in an hour,” said Blake, “this time, you’re drinking a full shake.”
He hung up. Alec looked down to see that his cock was leaking all over the floor. The amount of precum he was producing was unreal. What would it look like if he ACTUALLY came?
It didn’t take long to find out. The mere thought of drinking, pumping, and outgrowing Blake was hotter than any porn Alec had ever beat off to, and within seconds of stroking his impossibly meaty dick, he was spraying the mirror with jazz.
“FUUUUCK!” he growled. It spewed out of him like a broken fire hydrant, soaking the mirror, the ground, and his hairy tree trunk legs. He fell to his knees and panted like a thirsty dog.
I need to clean up, he thought, and he wasn’t just talking about the jizz. Alec had just an hour to do a days worth of manscaping. The hair on his chest seemed to get thicker and thicker, and with a FULL shake waiting for him at the gym, it was only gonna keep growing…
“You shaved,” was the first thing Blake said when Alec got to the gym. He’d gotten so wide, he practically had to force himself into his tiny Prius on the wya there. “Don’t worry,” Blake said before he could reply, “there’s plenty more where that came from,” and gave another wink.
Alec’s dick shot up in his shorts. He had to walk funny just to keep it from tenting the stretchy black material as they headed towards the machines. But he wasn’t just horny from thinking about Blake; there was a full shake waiting for him. More sweet nectar, more thick bulky muscles. More.
“I figured we’d start with arms toda--“
“Um… Blake?” Blake turned towards a nervous Alec. “I… um… you said you had a full shake today?”
Blake let out a belly laugh, which only made Alec hornier. “Damn, someone’s eager! Don’t worry, we’ll get there. You gotta pace yourself.” He put a heavy hand on Alec’s impossibly thick shoulder. “How about we start with chest?”
Alec wasn’t picking up his phone. In any other instance, Doug wouldn’t think anything of it, but their interaction at the gym yesterday had made him weary. He was in way over his head, and dealing with a substance Doug suspected to be very dangerous.
He tired calling one more time. As the phone rang endlessly in his ear, Doug began to entertain a new possibility: was he jealous? He had always wanted a body like Alec’s, and Alec had only gotten hotter since he started drinking this new protein shake. Was he right, yesterday? Was that what Doug always wanted?
“With just a sip or two from this drink, you could have that body tomorrow!”
It went to voicemail. Doug angrily shoved his phone in his pocket and made for the door.
How long had it been? Minutes? Hours? Days?
Alec didn’t know. He’d been standing at the machine for what felt like ages, doing bicep curls as Blake added more and more weight. As Alec shook himself out of a trance, he noticed the number on the weight he was now curling: 200 Lbs.
Impossible. Alec had never curled more than 100 on both arms. And yet here he was, effortlessly. How must he LOOK by now, he thought…
“Don’t stop,” a voice whispered in his ear. It was Blake, the smell of the protein shake still heavy on his breath. “I was right, you have a lot of potential.”
Alec tried to reply, but he just kept on pumping, power surging through his veins.
“I knew when I saw you that you were gonna get big. But man… this is something else!”
And that’s when Alec noticed his body. Every time his arms curled up, his biceps flared into two enormous footballs. When he looked down, he felt the bristles of his ever-growing beard scratch his chest, which rose voluminously with each consecutive breath.
Alec let out a final grunt as he lifted the bar and dropped it down again. Everything was sore. His arms, his pecs, his back, his legs. But it wasn’t from the working out: it was from growing so fast.
“You need to replenish,” Blake said, shoving something into his concrete chest. Alec could barely make out the shape of the bottle underneath his pec shelf. His heart skipped a beat. It was the moment he’d been waiting for for what seemed like eons. A full protein shake. Enough raw power to transform him into the biggest guy Blake had ever seen.
Next thing he knew, the bottle was empty. The sweet substance trickled down his throat and warmed his veins. He growled or primal satisfaction, like a beast after a hearty meal. And that’s when things started to change. Fast.
“Um… is your friend okay?” a mousy gym employee asked Blake, but Alec wasn’t paying attention. He had collapsed onto his knees, and was now watching his body evolve with alarming speed. The last two times he’d drunk the special shake, the results took hours to kick in. Now, having consumed a complete dose, they were taking seconds.
“Yeah, I think he just needs to use the bathroom,” Blake reassured him, helping Alec to his feet and walking him over to the locker rooms.
The second they were inside, Alec screamed. “AGGGGGH,” his voice echoed throughout the empty room, a mix of pain and pleasure as his body went from big, to bigger, too biggest. His arms ballooned out, his pecs rising to his chin like blimps. But the most startling change was to Alec’s mid section. Gone were the abs he’d worked so hard on carving out. As Alec’s stomach grumbled, his mid section exploded out into a hard, heavy muscle gut.
“What’s happening to me?” Alec groaned. Blake just stared at him, awestruck.
“I… I’m not sure.”
“What??” Alec’s voice was deep and raw. He was sounding more like an animal than a human being.
“You were kind of my guinea pig, bro” Blake said. “I’d only had a little bit of that stuff, I was curious to see what is was capable of and… man.” He stepped back to admire all of Alec, who was taking up more and more space on the bench.
“You… turned me into… A MONSTER!”
“You kidding?” Blake leaned in, “I made you a god. You wanted to bulk up? Now you’re ALL bulk. 100% muscle and fat and hairy goodness. You should fucking thank me, bro!”
The second he said “hairy goodness,” Alec felt a tickling on his chest. All that time spent shaving his copious body hair only to have it grow back in seconds. But this time, it grew with a vengeance. He was so busy watching his pecs erupt with black fuz, that he didn’t notice Blake drooling over his body.
“Fuck dude…” Blake peeled off his tank top.
“What... what are you doing?” Blake didn’t respond. He ripped his shoes off and pulled his shorts down, unveiling a bulge the size of a grapefruit.
Alec went dizzy. The next thing he heard was a loud RIP as he felt his body outgrow the tiny gym shorts that used to be so baggy on his slender frame. His dick, an impossible 12 inches long and thick as a soda can, tore through his underwear and throbbed in the cool air of the locker room.
He fell backward, unable to support his new bulk, and looked down over his muscle mounds to see the massive figure of Blake, drooling at his cock while stroking his.
It was what Alec had dreamed of. The fantasy that had plagued his mind for days.
“Worship me,” he growled at Blake. Dazed, the man walked over to Alec and mounted him like a stallion. He felt Blake’s ass slide up and over his cock, teasing the head a bit before swallowing it whole.
Blake let out a cry. He was talking all 12 inches, his face contorting with pain and his muscles glistening with sweat. Alec ran two giant hands up the length of his thighs as Blake admired the breath and width of Alec’s new, hairy chest. And then, he started to ride him.
They didn’t care if anyone walked into the bathroom. They were so focused on each other’s bodies, so enraptured by the other’s scent, they could have spent hours worshiped themselves.
But Blake’s ass was so fucking tight, the protein shake had made Alec so inhumanly horny, it was just a minute before he growled in that deep animal voice: “I’m cumming.”
Blake didn’t get much warning, but he didn’t care. He threw his head back as he took Alec’s torrential load, riding him like a prized stallion while Alec convulsed and contorted. His seed leaked out of Blake’s ass, and he opened his eyes just in time to see the man put on a few extra pounds of bulk, not to mention a fresh batch of hair on his chest.
“Fuck bro,” Blake growled, admiring the new size of his body, “it’s like getting a protein shake up my ass.”
Alec laughed. His laugh sounded strange now, his body reverberating in a completely different way. He hadn’t just put on weight; he’d put on years. There was no way this was the body of a man in his 20’s. Alec had to be 30 now. At least.
“Do you have any more?” he asked Blake.
“Of the shake?” Blake raised an eyebrow, “you wanna get bigger??”
Alec grinned, “not necessarily…”
“Alec! Alec!” Doug called out for his friend, but he’d already looked around the whole gym. Twice. He was nowhere to be found. Maybe he isn’t here. He’d only assumed Alec went to the gym to see his “dealer,” but maybe he was at home. Maybe he’d come to his senses, and maybe they could put all this nonsense behind them.
But that’s when his eye caught something. Alec’ familiar dark hair, his jovial face. Except it was trapped under more hair than he’d even had on his head, and more muscle and fat than the two of them combined.
“A…Alec…?”
The man looked up from his phone. “Hey bro,” Alec said in a voice that was so deep, it bordered on unrecognizable, “glad you could make it!”
Doug was staring flabbergasted at his belly. Here was Alec, the guy who used to be so anal about maintaining his perfect six pack, now walking towards him with a hairy muscle gut practically spilling over his gym shorts.
“What happened to you?” Doug said. He was too in shock to be angry, or sad, or frustrated. He just needed to know.
“The same thing that’s going to happen to you,” a familiar voice said from behind him. Doug spun around to see Blake, another protein shake in his hand. Even he looked different—though only marginally compared to Alec, with slightly bigger muscles, slightly more fat, and a lot more hair.
Doug shook his head. “No. I… I can’t…” As he tried to back away, he bumped into a pillar of mass. It was Alec, who now towered above him and emitted a powerful smell. Though Doug hated to admit it, it was a huge turn on.
“One sip,” Doug said, reluctant. “That’s it.”
Blake and Alec smiled at each other, and he handed Doug the shake. Doug looked down at it. He had half a mind to drop it and take off running. That would be the smart thing to do. After all, he had no idea what this was, and the only thing he did know was that it had turned his gym buddy into a monster.
But Doug had always wanted to be like Alec. He’d always wanted his body, his looks. He was one sip away from looking exactly like the first he’d always envied. One sip…
Doug took a gulp. The sweet, rich substance leaking down his throat. The second it hit his stomach, his mind went blank. One sip became two sips became three sips became—
It was gone. Doug dropped the empty bottle in horror as he realized that he’d gulped down the entire shake. All at once. He waited for the two men to react accordingly, but instead, they started roaring with laughter. As if this is what they were expecting.
“What’s so funny?” Doug demanded. “What’s going to happen??”
Alec stared down at Doug’s chest in pleasant surprise. “I think you mean ‘what’s already happening.’”
The words sunk into Doug’s head. He didn’t want to look down at his chest, but both men, with their eyes fixed on his tank top, were making it incredibly difficult.
Finally, Doug glanced downward. For the first time, he couldn’t see his toes. His pec shelf had grown larger in seconds than it had in years of training. Impossible.
Blake reached in to sneak a peak at Doug’s new pecs, but he swatted his hand away. “No!” he cried, “No, this… this isn’t happening, it’s… is my voice… deeper??”
Indeed it was Doug was starting to sound just like Alec, a depth and maturity to his vocal cords that was matched only by the rapid maturation of the rest of his body. His arms, his legs, and his shoulders followed the growth of his pecs, and within less than a minute, Doug was leaning on the two men to keep him upright, as the exponential bulking make him heavier and heavier.
“Don’t resist it bro,” Alec whispered in his ear. Doug felt the bristles of his beard tickle the side of his face as he said, “you’re gonna be so big. I promise.”
The thought sent a wave of pleasure throughout Doug’s body. Much like Alec, the thought of joining these two men in pure size heaven was more than enough to offset the fear of changing so fast.
And change he did. Doug let out a primal growl as pounds and pounds packed onto his frame. The tiny kid who could never built any muscle wasn’t so tiny anymore. His chest puffed out and his arms flared upwards, and each time he looked down at his body, he seemed further and further from the ground.
“Damn, you’re friend’s got some serious potential!” Blake remarked. Doug barely noticed, because the next phase of his transformation had begun. In an instant, he felt a new sensation overtake his entire body. He scrunched his face as he sensed a thick, bushy beard sprout over his previously postmarked skin.
He clawed at the edges of his shirt. He needed to see what he was becoming. He needed to prove to himself that he’d finally grown as hairy as Alec. As big as Alec. Bigger than Alec.
“Fuuuuuuuuck.” Doug took a moment to admire the sheer size of his new body, and watched as the final bits of his transformation took effect: his stomach hardening into a thick, muscle gut just like Alec’s. A treasure trail of hair growing like a runway down towards his dick. And though Doug wasn’t going to drop his shorts in the middle of the gym, he knew there’d been some serious growth in that department as well.
They practically owned the gym from then on: Alec, Doug, and now Blake, hitting the machines, downing protein shakes, and checking out their enormous bodies. And when no one was looking, they’d all three sneak into the locker room for a good fuck.
The three were there almost 24/7. But of course, who could blame them? They’d put all that energy into bulking up. Now, it was time for cutting. To work off all that fat and unveil the raw, hard muscles underneath.
It was time to get shredded.
