It was supposed to be an ordinary day like any other when Geovanni R. Diaz stepped into the gym that afternoon. He drank his pre-workout in the front lobby while waiting for his friend/gym partner Evan Washington to arrive. The two men had met at the beginning of summer when they both started hitting the gym on the same day. They bonded over making fools of themselves as they misused several exercise machines. They became close friends and regular gym buddies since then. 

Some 20 minutes had passed, and Evan was still nowhere in sight. Geo finished the last few sips of his pre-workout and decided to start without him. It was common for Evan to flake out, especially as of late. While Geo initially shared Evan's casual approach to the gym, he eventually decided he wasn’t satisfied with doing the bare minimum. He took on an intense 60-day workout regime to really challenge himself. Evan supported his friend’s endeavor, but the differences in their goals eventually showed themselves when Evan regularly skipped days while Geo kept at it. He didn’t take it personally; he had grown used to it, although he’d be lying if he said he didn’t miss having someone to joke around with between sets. Regardless, Geo claimed a chest fly machine, powered up his headphones, and then proceeded to get to work. 

“Hey papi, mind if I work in with you?” 

Geo heard a familiar voice behind him as he finished his warm-up set. He smiled as he turned and saw Evan leaning against the machine. 

“Hey, handsome, I thought you weren’t coming today.” Geo stood up and embraced his close friend. 

“Wasn’t planning on it if I’m being totally honest, but then I decided maybe I’ve been skipping too many days and forced myself out of bed to come here. Did you just start?”

“Yeah man! It’s chest and shoulder day today so I figured I’d start with my favorite machine,” Geo looked at Evan with a grin. “Care to join me?” 

Evan only laughed in response. They both already knew the answer, but they enjoyed asking anyway as a joke. With that, they proceeded to go through Geo’s workout plan together. Naturally, Evan couldn’t keep up with Geo anymore and had to lower the weight after every set, but that didn’t stop them from enjoying their time together. By the end of the workout, they were both tired and sweaty in the locker room after hitting the weights hard.

“I have no idea how you manage to stay on track with this whole fitness challenge thing…” Evan huffed as he caught his breath. “I’d probably give up after the first day. You look good though! Your hard work is paying off and it really shows!”

“You think so?” Geo said as he wiped the sweat off his brow. “It’s hard to tell sometimes. I look in the mirror and I feel good, but then I stare at myself too long and I start worrying if I’m just lying to myself.”

“That’s just body dysmorphia talking, you look great!”

“Aw thank you Evan, you’re too kind.”

“Of course! Anytime you need reassurance, I’ll always be here.” 

Evan flashed Geo a broad smile, and he smiled back. A few minutes passed before Evan started talking again. 

“Hey, are you free tonight? I was thinking of making my world famous lasagna tonight, and I'd love to have you over for dinner.”

Geo stopped drying himself after he heard Evan say that. He turned slowly to Evan and saw him with a shy smile. The same smile formed on his face as he began to answer.

“I would love to have dinner with you, Evan. Of course I’ll come over tonight.”

Evan practically exploded with excitement. He ran to Geo for a hug, almost knocking him over due to the impact. Geo wrapped his arms around Evan and held him in a tight embrace. Their hugs always put Geo in a good mood. He was more than overjoyed to discover that Evan shared his feelings. He knew this hug would quickly become one of his top favorite memories. It was a tender moment between two men falling in love, which made it all the more noticeable when loud indigestion ended their sweet moment abruptly. Geo pulled away and held his stomach as he kneeled over in pain.

“What’s wrong? Are you okay?” Evan asked. 

“Ugh… I’m fine. I think I just need a bathroom. I’ll be right back.”

Geo ran off while Evan stayed behind in the locker room. Evan finished packing up their things while he waited. Ten minutes passed, then twenty, then thirty. Growing worried, Evan walked to the bathroom stalls to check on his beloved friend. He heard heavy, labored breathing coming from the only closed stall. 

“Hey, is everything okay?” 

Evan knocked on the stall door and found that it was unlocked. He pushed it open slightly. His jaw dropped to the floor when he found Geo naked and drenched in sweat on the tile floor. His eyes were clenched closed, and his face was distorted due to unbearable abdominal pain. Evan ran to his side. 

“What’s going on!? What’s wrong?” Evan asked with apparent urgency in his voice. Geo could barely get words out as he was too busy hyperventilating. 

“So… Hot…”

Evan held a hand against Geo’s forehead and almost immediately recoiled from how hot it was. Geo was running an extremely high fever, unlike anything he had ever seen! Evan’s eyes darted around the bathroom as he desperately sought solutions but couldn’t think of anything due to his panic. He was desperate. He knew he needed to act fast before—

“Ohhhh it hurts!!”

Geo’s sudden shriek stopped Evan’s negative line of thinking. At that moment, time seemed to slow down to a crawl. Evan’s gaze shot back to Geo. His eyes nearly popped out of his head when he saw what was happening to his soon-to-be boyfriend. Unbeknownst to both of them, Geo was a carrier for the Metamorphosis gene, and all the right conditions were met for it to awaken. The gene was hard at work rearranging Geo’s DNA, and he began transforming right before their very eyes! 

It began with his body hair. Like the other men from the paternal side of his family, Geo had never been able to grow much body hair, if any. However, he did have the genes needed for ample body hair, and thanks to the MM gene, it was finally able to express itself. Thick, black hair began sprouting out of his legs in spurts. With each hair follicle that grew in, Geo’s legs grew just a little bit thicker than before, causing Geo to moan obscenely loud as a result. The accelerated hair growth traveled up his legs and into his crotch area where his pubic hair grew in at an alarming rate until he had a jungle of bushy pubes covering his groin. His hairy balls hung lower than before after growing in size and his cock grew an inch thicker in width. Within a few minutes his entire lower half was transformed. His legs became as strong as tree trunks, and with a new, well-endowed package to boot— all covered in a thick layer of hair too! 

The transformation wave continued to ripple throughout the rest of his body. Geo twisted and writhed on the floor as the rest of his body underwent rapid changes. A prominent happy trail formed on his lower abdomen, connecting his belly button and pubic region with a line of long, messy hair. His pecs grew more plump as hair ran up his ab line and onto the center of his chest where it spiraled outward until it formed little rings of hair around his nipples. His chest and abdominal areas were only covered with a slight dusting of body hair compared to his legs. The stubble on his face grew until a thick, connected beard replaced the short goatee Geo once sported. 

His armpits were hit the hardest by the transformation. His pit hair grew and grew until it curled from its long length, leaving Geo with obscenely hairy underarms. Combined with the heavy sweat of an intense workout, Geo’s hairy pit smell began to fill the room. Evan recoiled from how unexpectedly strong Geo’s musky body odor had become, though he couldn’t resist helping himself to a couple of sniffs after he got a whiff of his powerful musk. 

The MM gene had thoroughly scrambled Geo’s DNA sequences, leaving him as a completely unrecognizable, alternate version of himself! 

“WHEW!! God I feel sooo much better now… Hey what’s wrong, babe? You look like you’ve just seen a ghost.”

“G… Geo? Is that you?” Evan stood in shock from disbelief. If he hadn’t witnessed it for himself, Evan would’ve never believed that the hairy, smelly jock lying in front of him, staring at him with a lustful smirk, was the same man he had just invited over for dinner. 

“Of course it is, mi hermosito, who else would I be?” Geo winked as he threw his arms up, leaving his hairy underarms exposed. “By the way, I saw you sniffing the air earlier… How about you come and have a whiff right from the source?” 

Evan chuckled nervously, but Geo wasn’t joking. His laughter died down as he realized just how dead-serious Geo was.

“No… You’re not seriously—” 

“Oh but I am,” Geo interrupted. “Just a little taste won’t hurt anyone. Call it a preview for what’s to come later tonight.”

“But right here? In the public bathrooms?”

“Why not? It’s not like anyone else is around right now. We’ll just have to keep our voices down if someone comes in. So, what do you say? I know you want to…”

Geo got up from the ground and approached Evan. He stood close enough that his scent naturally filled Evan’s nose without him needing to sniff. Evan’s eyes rolled to the back of his head as his friend’s intoxicating musk left him in a state of deep arousal. Of course, Evan had some reservations about hooking up with Geo after he had just randomly transformed right in front of him, but between how close Geo’s pits already were to his face and the fact that it still seemed to be the same man he had come to know and love on the inside, Evan couldn’t bring himself to reject the offer. Before he could think about it properly, he was already leaning in without even realizing it. 

Once Evan started, he couldn’t stop. He buried his face deep into Geo’s sweaty, rank underarms. Geo’s coarse black hair tickled Evan’s nostrils as he nuzzled against the crevices of his pits. Muffled groans filled with pleasure escaped Evan’s mouth as he indulged in the manly, sweaty scent, each sniff leaving him more satisfied than the last. Soon enough, both Geo and Evan grew rock hard from all the sensual physical touch. The tents in their gym shorts poked and rubbed against each other as they continued pressing their bodies together. For Geo, the thought of getting worshiped in a public place like a gym bathroom was the hottest thing ever while Evan was just happy he got to service a hairy, sweaty gym rat. 

Evan briefly lifted his head out of Geo’s armpit for air. At that moment, Geo held his face and planted a firm kiss on his lips. Their tongues wrestled inside of Evan’s mouth as they locked lips. Once they had their fill of making out after a while, Geo began pushing Evan down onto his knees, to which Evan happily obliged. Geo’s cock stood at full mast, nearly poking one of Evan’s eyes out as he got into position. Evan was in awe as he held the heavy piece of uncut brown meat in his hands. He was drooling just from the sight of it! Not able to restrain himself anymore, Evan dove right in and guided the leaking tip into his mouth.

Arghh… Mmmmm…

Geo let out guttural moans as his friend went down on him. The sound of a man’s deep moans encouraged Evan to service him as best as he physically could. It was almost like he forgot he needed to breathe as he slurped Geo’s entire length up and down with his tongue until it hit the back of his throat. Geo squirmed and grunted obscenely loud as Evan wrapped his cock with his warm, moist mouth. He only lasted a few minutes until he couldn’t hold in his load anymore. Geo held Evan’s head down, his nose pressing against his unruly bush, and let out a loud groan from deep within his lungs as his load came rushing out. Evan whimpered with pleasure as he swallowed Geo’s heavy load, the salty taste of cum filling up his mouth. Once it was done, they both pulled away with a satisfied ahhh!

“Alright, get up. Your turn.”

Geo helped Evan up to his feet, then got down on his knees himself. Evan didn’t deny Geo’s advances, but he also didn’t help him get into position either. He had a blank expression as Geo proceeded to go down on him. Even as he swirled and sucked on his sensitive head, Evan didn’t react or say anything aside from an occasional soft moan. All he could focus on was a prominent cut on the inside of his cheek that he could feel with his tongue. Was that always there? Evan wasn’t sure, but regardless, it was already too late. The damage was done. He had contracted the MM gene from Geo. 

Evan winced as he began to notice a pain growing in the pit of his stomach. It started as a slight ache, but it quickly became unbearable. Evan hunched over, letting a low groan as he held his hands against his side where it hurt the most. It felt like he was being stabbed from the inside out! The next thing he knew, his muscles rapidly stretched and constricted as the gene started rearranging his DNA. 

Because Evan was a non-carrier and his immune system was not already accustomed to suppressing the malignant virus, the MM gene was able to activate without delay and transformed him much faster than Geo. He threw his head back and quietly moaned as the transformation happened. Geo was too busy giving him head to even notice. He just thought he was doing a good job. 

The MM gene was hard at work bringing out Evan’s hidden genetic traits. Although he was only 12.5% Black from his mother’s side, that was more than enough for the virus to play around with. Various points around his skinny body began to inflate with muscle mass. His thin frame and scrawny chicken legs filled in with much-needed mass, giving him sturdy legs with sharp ab lines and impressive cannons for arms. His biceps swelled to the size of melons as his body flexed under the tension of rapid transformation. Evan himself was surprised with how heavy his new body was becoming.

His facial structure shifted and morphed. His nose widened while his jawline became stronger and sharper. A bushy goatee beard grew in where he once could only grow peach fuzz. The once wholly flat-chested Evan Washington now sported two massive slabs of meat resting on his torso. His pecs were firm, strong, and hung low from their own weight. Coupled with bright pink nips, it wouldn’t be a stretch to say he now possessed a perfect chest. Although his pale skin tone stayed the same, the MM gene brought his Black features out to the forefront, giving the once undeniably White young man a more visibly biracial appearance by the end of his transformation.

While Evan underwent a total identity change, Geo kept blowing him all the while. Although he did notice a sudden change in Evan’s girth and overall size, the taste of a nice, sweaty cock kept him focused on the task at hand. Geo simply took a breath through his nose and opened his mouth up even wider to keep deepthroating him. Evan’s body was still sensitive from having undergone rapid growth, which only made the pleasure of having his dick sucked sloppily increase tenfold. The veins in his thighs and cock twitched and throbbed as he climaxed and pumped out his thick load straight down Geo’s throat. Geo swallowed, sighed with deep satisfaction, and got up from the ground. 

“Mmm! You know, yours tastes kinda tangy!” Geo gathered and licked up the few stray drops dripping from Evan’s tip. 

Meanwhile, Evan was trembling, struggling to breathe after all the physical stimulation. Only after Geo finished cleaning up the spunky mess did he realize that the Evan standing before him no longer looked like the Evan he once knew.  

“What the— Who are you!! Where’d Evan go?” Geo yelled. Evan turned to look at him, and Geo saw his pupils dilating unnaturally rapidly. “Dude, what’s wrong with your eyes!?”

Evan said nothing in response. The MM gene fried his mind with a heavy concentration of hormones, leaving him in a state of severe brain fog. Evan stumbled forward to the nearby mirror. His cock was still semi-erect. The sight of his own dick was enough to make Evan drool as he admired and flexed his arm muscles. Geo tried calling his attention but to no avail. Evan was unresponsive to his shouts. He had one thing and one thing only on his horny mind. 

“More…” Evan muttered.

“More what?” Geo replied. Evan snapped his line of sight back at Geo. His dazed eyes wandered to Geo’s exposed junk, then narrowed as they met his eyes. He let out a low growl as his eyes suddenly had an intense look that caused Geo to take a few steps back. It was the same look a hungry lion gave a gazelle out in the wild. Geo swallowed his breath. He became acutely aware of the situation he was in.

“Dick! I want more dick!!”

Evan puckered his lips and lunged towards Geo, though Geo managed to sidestep him in time.

“Get away from me! Look man, you might be hot as hell but I’m not interested! I’m a taken man!!” 

Geo quickly gathered his discarded clothes and hightailed it out of the bathroom. Naturally, being in the hyper state that he was, Evan wasn’t going to give up until he got what he craved. He stumbled out of the bathroom stall ass naked, where he was about to run into the perfect target.  

“Man! Today is just not my day,” a bodybuilder mumbled as he walked into the locker room. Dylan was a muscle gay, and he came to the gym solely to go cruising that day. 

However, despite his efforts, he struck out. He was getting sexually frustrated, which made him incredibly willing to hook up with some random stranger in the bathroom. 

Dylan was as equally surprised as he was impressed when Evan stepped out of the stall with his cock out. The smell of sweat and cum hit his nose, arousing him. Dylan loved what he saw and decided to make his move on the muscle-bound hunk.

“Hey there, stud! Need a hand there?” Dylan whistled at Evan, catching his attention.

Evan turned to him. He was still visibly sweaty and was breathing heavily. Dylan wasn’t sure what to make of him, but Evan didn’t give him a chance to reconsider. 

Evan charged at him, planting his lips against his upon impact. Dylan was caught off guard but had no problem matching Evan’s energy. He kissed him back as their frisky hands began feeling up each other’s bodies. Although Dylan loved making out, Evan’s kissing style was quickly turning out to be way too rough for his tastes. Evan forced his tongue in, had an obscene amount of saliva, and even bit down on his bottom lip with enough force to draw blood.

“OWW! What the fuck man!?”

Dylan pushed Evan away and held his bleeding lip. He was glad that there wasn't a lot of blood, but was still rightfully pissed off. As ravenous as he was due to the MM gene, Evan was oblivious to what he had done. Instead, his attention shifted to another guy wearing only a towel near the showers. He ran off in that direction and left Dylan in the dust. 

“Prick…” 

With that, Dylan decided to just give up and get a quick workout in. He took out a rice bar and ate it as he returned to the main area. He did his stretches, picked up a couple of barbells, and claimed an open bench. But just as he was about to start his first set, a powerful hunger overcame him. He grabbed at his stomach and kneeled over in pain as the MM gene took effect.

All of Dylan’s hard-earned muscles melted away within a matter of minutes. He rapidly gained pounds upon pounds of body fat. What were once washboard abs complimented by chiseled biceps were replaced by flabby arms and a protruding, hairy gut. His pecs lost their firmness and began to sag as they became nothing but a pair of man boobs. All the while, the same overwhelming lust Evan had began growing within Dylan too.

A handful of nearby good samaritans came to Dylan’s aid after he collapsed. While they all tried to help Dylan, most stayed back after witnessing his sudden transformation firsthand. Nobody knew what was happening behind the scenes, leading to anxious rumors and worried whispers floating around the gym. While most people were too cautious to get near Dylan, one brave man decided to step forward and help Dylan. Unfortunately, as he tried to help Dylan get up to his feet, Dylan accidentally scratched him on the back. The young man recoiled and dropped Dylan to the ground as a result.

As other people began to help Dylan, the injured man stepped off to the side to tend to his wound. He felt unusually warm as he finished putting on a bandage. He didn’t think much of it and ignored it but soon found himself sweating bullets as he rejoined the group. It got to the point that he needed to take a seat to try to cool off, but it was no use. He soon joined Dylan on the floor, writhing in pain due to contracting the MM gene.

At this point, everyone in the gym had gathered around the two men. The crowd stood back as they bore witness to yet another transformation. They watched in bewilderment as the short man rapidly grew in height. He groaned and gasped in anguish as his limbs stretched out. His torso grew and widened until he had the body of a tall bear. He pawed at the growing tent in his sweats as he thrashed around the floor, massaging his manhood as hormones continued pumping throughout his body. Within minutes, the infected man had gone from a stout 5’4 to a big, burly 6’4.

Although the afflicted man already had a healthy spattering of trimmed body hair, the MM gene forced his hair to grow to what was genetically possible. His body hair grew out beyond what Geo experienced. From his chest and belly to his legs and arms, every hair follicle grew longer and thicker, leaving him a pelt of curly body hair. His facial hair, in particular, grew out the most. His mustache grew longer and longer until it practically covered his mouth! His beard became bushy and unruly with coarse black hair as it reached his chest. All the while, the hair on the top of his head fell out one by one until he had a shiny bald head. He became an unrecognizable version of himself thanks to the MM gene. Once his transformation was over, he sat up and let out a bellowing belch that echoed throughout the gym. 

“Mrmph… Feels sooooo good…”

The crowd of witnesses backed away from the two transformed men. The two men turned to the crowd and smiled. A cold, ominous air filled the atmosphere. A few intuitive individuals saw the writing on the wall and left before shit hit the fan while the majority stayed behind, anxious and confused at what was going on. A few moments filled with tense silence passed, only for it to be broken when Evan came charging in from the men’s locker room and locked lips with the closest man. Almost as if on signal, Dylan and the burly bear joined Evan’s rampage and lashed out, too.

Pandemonium broke out as everyone made a mad dash for the exit. It was like a zombie attack as Evan and the other transformed men attacked every healthy man they could get their hands on. The unfortunate victims contracted the MM gene. Once infected, they, too, succumbed to genetic rearrangements. Some grew insanely muscular, and others became incredibly overweight. Hair was grown and lost; skin colors changed, and every physical feature rearranged until they were completely unrecognizable. All those transformed men wanted nothing more than to kiss, fuck, and spread their seed to as many people as possible until their hyped-up urges were satiated. 

“Shit’s getting crazy out here…” Geo whispered to himself. He poked his head out of the locker room and saw the chaos he unwittingly caused. He wanted nothing to do with the madness and ran out of the gym as fast as he could, though the infected men paid him no attention as he was already one of them. Police were beginning to arrive on the scene as Geo drove away with only one thought: his dinner date with his best friend and crush, Evan. 

Though unfortunately for him, the Evan he knew and loved was long gone. It would only be a matter of time before Geo forgot all about Evan, and his body gradually returned to its original state after the MM gene returned to a state of dormacy.

At least, until the next time Geo or some other carrier falls in love.

PUBLIC STATEMENT ISSUED BY THE SHERIFF’S OFFICE

Good evening.

As you may have already heard, a horrific incident has occurred at one of our local gyms. Dozens of men went on a rampage. It took several hours and almost all of our manpower, but our police department has successfully arrested all of the sexually rabid men and have placed them in custody. 

Security camera footage shows that all of these men were physically transformed before attacking. After an initial investigation, medical experts suspect that a rare genetic disorder called the Metamorphosis gene is responsible. Unfortunately, while there were no casualties, some of our own brave policemen were affected by the viral outbreak and were transformed themselves.

Two big questions remain tonight: how did a genetic disorder manage to spread like a virus, and how did these men contract this previously unheard of disorder? The arrested men were questioned about the events that led to this mass riot. None have been able to provide any concrete information. None of them seem to recognize their former identities, citing amnesia and severe migraines as the cause. 

Patient 0 has yet to be found. An active investigation continues as research efforts for a potential cure to the Metamorphosis gene’s effects continue.
