SCIENTIFIC GAINS 

Johnny stood barefoot on the cold concrete sealed floor; he shifted his weight on his frail legs.

“Can you remove the glasses?” One of the examiners requested standing behind the crystal clear plexiglass.

Johnny nodded and took off his black glasses. He glanced around the empty room and placed them on the floor outside of the red circular mark he was standing in. His vision was a bit blurry.

“Okay we’re going to be beginning the test soon. For the record please state your name, height, and weight.”

The other examiner looked around his desk and pressed a button giving Johnny a thumbs up, the recording had started.

“I am Johnny García, twenty five years old, weight, one hundred and thirty pounds, height, 5 foot 9 inches.”

“Great, so.. Johnny, what made you want to participate in this experiment?”

“I've always wanted to improve my body but I’ve struggled with gaining muscle for a long time. Mostly due to genetics.”

Two of the examiners were quickly jotting down information, clutching their clipboards. They were all slim, and nerdy. Johnny didn’t want to be like that, he could feel a beast within himself, always hungry to become huge.

“Why do you seek improvement? For yourself? Or for the attention of others?” The vigorous writing halted as all of the scientists waited for Johnny’s response.

“Both.” He responded.

Johnny knew deep down it wasn’t all for him, he wanted the attention.

He constantly daydreamed about flexing his enormous biceps and watching them bulge bigger the more attention he got. This was his chance.

He knew there was a risk of major side effects, but he didn’t care. Johnny had signed the paperwork with confidence in his decision.

He wanted muscle.

There were two other guys joining him in these trials

Marco and Diego, they weren’t muscular, but bigger than him. Marco was wide and big with a gut, Diego was fit but still on the frail side.

they were off in their own containment units. Probably starting now.

 ----

“Okay, we’re going to begin the trial.” There were a few more scientists in the lab, typing away

Suddenly, with a click, a low hum began to buzz in the empty space. Johnny’s brown eyes looked around and met back with the examiners.

“We aren’t fully aware of how this formula feels, but if you feel any discomfort, please, let us know.”

Johnny nodded, he could feel his heart begin to pump in his chest hard and fast. It was a mix of excitement and nerves.

Two small doors on opposite sides of the walls smoothly opened to a metallic pipe-like shoot that slowly pushed out of the wall erect.

Johnny stared, he could feel his heart beat in his throat and temples.

The humming suddenly stopped, and the unit filled with silence.

The two pipes began to pump dense clouds of deep fog that slowly sunk to the floor and billowed outward. Like a drop of ink in a glass of clear water.

Johnny swore he could hear a quiet low sigh, or moan coming from the fog… almost like the sound of men making low groans.

The fog wafted up Johnny’s leg

Hm, nothing..

Once he took a deep breath he realized the insane powerful smell of it. It smelled primal, manly, ripe, and… horny…

The dense fog continued to rise up his body, Johnny could hear those deep groans and moans get louder.. and deeper..

The scientists put down their clipboards and watched…

Johnny’s whole body was tense.. the veins in his arms and neck were bulging, he could feel a deep pleasurable sensation all over his body.. he couldn’t think of a word to describe it. But it felt so fucking good…

The scientists watched in awe as Johnny opened his eyes, pupils dilated, his pecs began to rapidly fill his tank top, filling them to the brim.

Johnny lifted his chin and allowed the growth fog to fill his flaring nostrils; huffing deeply… his frail 5’9” 130lbs body now swelling and rising into a 6’3” 190 lbs muscle jock

“fuuuck..” Johnny grunted, his voice was deeper than before.

His enormous pecs bulged huge and pushed outward ripping the center of his white tank top. His traps began to swell and his deltoids and biceps bulged like he just got out of the gym with a hot dirty pump.

His core began to tighten and ripple; creating a thick wall of hard, chunky, cinder block abs... the dense fog kept pumping from the pipes filling up the unit, giving examiners a distorted view of Johnny’s scientific gains.

The growth came to a halt and the examiners watched with inquisitive, awe-filled expressions.

A deep, masculine moan rumbled from inside the large cloud of dense fog; Johnny’s hard muscle jock body began to rise and swell from it; completely ripping his tank top off

His enormous hairy pecs bulged and bounced, Johnny grinned and flexed a double bicep letting out a low resounding laugh.

“Oh fuck yeahhhh…”

Johnny studied his new monstrous physique; he stared down his freaky 12 pack abs that created a gaping valley like crevice.. he flexed his abs and rolled his hard wall of muscle… flaring the thick wide Adonis belt that framed his o-shaped belly button; his muscle core was a defined arrow that guided Johnny's eyes to his thick, bushy, curly pubes that were pushing up out of his underwear.

“Oooohh.. fuuoock” he felt his thick cock lurch hard, his huge hand groped it. More of the fog wafted up Johnny’s hard, bulging muscle bod. He could feel his brown nipples harden.

He reached peak masculinity. But he wanted more.

The scientists all watched in absolute awe. The experiment worked! They all tried to hide the enormous boners that forcefully filled their slacks and jeans.

Who could blame them? Seeing all that rock hard fuckin’ muscle could make any dick hard and beg to be stroked.

The humming suddenly stopped and the fog began to dissipate.

----

Johnny looked up from his massive ripped muscles, intensely staring at the examiners. He didn’t want it to end.

“Why’d you stop?” He asked, watching the thick fog dissipate.

“We need to record your results and ask you a few questions. This is a monumental success!”

Johnny laughed, proudly flexing his enormous 28 inch biceps, watching the hard beef ball up and bulge upwards.

“How did it feel?”

“It felt so… good” Johnny continued flexing both arms and looking down at his enormous full pecs, bouncing and flexing them.

The examiner paused a bit, becoming entranced in Johnny’s massive muscle. He cleared his throat and quickly continued.

“The results are great, we’re going to measure your sta-“

“Can I get more?” Johnny asked

The examiner paused.

“We’ll have to wait and see, we don’t know the full extent of the side effects you may experience. Now that you’re bigger, way bigger, everything else is elevated to a substantial degree.” He explained

Johnny noticed that his vision wasn’t blurry anymore; he could now see every face vividly. He hadn’t realized that every examiner in the facility was male.

Johnny could feel his big balls churn with a thick load of cum. He felt a deep powerful lust, almost like he could tell how horny everyone in the control room was feeling for his big muscles.

Johnny pushed the thought aside and was led to another large room to check his vitals.

--

Johnny sat on the examination table. It looked tiny compared to his towering size. His shoulders were thick and broad, he was wide and diesel. Johnny noticed his slight tan, giving a low bicep flex watching it bulge and a nice vein swirl around it.

But it wasn’t enough. He kept thinking about how he could be bigger. If only they gave him more of that growth fog, then would he feel big enough?

The door opened and a man entered. He smiled and nodded, studying Johnny’s massive build while setting down a file.

“Wow, look at you! They really pumped you up.” He grinned.

Johnny chuckled

“I’m Dr. Atkinson but you can call me Geoff.” He reached out a hand, Johnny noticed how large his hand was compared to Geoff’s. He made sure not to squeeze too hard.

Geoff was quite buff himself, he wore a tight shirt with slacks. The fabric gripped around his swole body and you could tell he had great abs; his pecs were quite noticeable too, Johnny couldn’t help but take a few glances.

Geoff pulled the swivel chair and took a seat, his pants rode up and pushed out his big package. He had a neatly trimmed goatee and a strong jawline. He was a stud.

Horned up thoughts began to fill Johnny's mind and he could feel something slowly growing and hardening within his shorts.

Geoff continued explaining and asking questions about how Johnny was feeling.

“Seems like you’re doing great. Just gonna check some vitals.”

He stood up and began using the stethoscope. The cold metal pushed against Johnny’s hard, massive, pecs.

Geoff noticed the enormous bulge rising up in Johnny’s shorts, it billowed up and throbbed. Johnny couldn’t stop it, the more he tried, the harder it got and the hornier he felt. His cock began to ooze a thick rope of pre cum, sputtering on the floor.

“Excited?” Geoff grinned

“That’s a healthy sign, everything a man experiences is usually ten times more intense after treatment.” Geoff kept staring at Johnny’s enormous bulge, entranced in the rawest form of masculine lust.

Geoff asked “May I?” His hand was gesturing to rub Johnny’s pecs.

“Of course.”

This is what Johnny always wanted. To be admired, to induce boners, to make a room fill up with lust. To make men cum for his muscles.

Geoff’s hands slowly rubbed Johnny’s hard nipples, his boner immediately reacted, lurching hard and rising in his pants.

Johnny moaned deeply

“Fuck yeah, that’s it…” Geoff bit his lip watching Johnny's ripped, freaky, rippling body become nourished from his worshiping hand.

Johnny quickly placed his other hand on his other massive pec, spreading his legs wider to give his enormous bulge more room to throb.

“Aw fuooock..” Johnny erupted, Geoff’s hands stroked and rubbed his pecs and hard nipples, his slacks were now full of massive boner.

“You like this first check up man?” Geoff asked, his horny masculine tone only made it better.

Johnny responded with a primal answer; “Fuck yess, suck my fuckin’ cock..”

“Aw fuck yeah..” Geoff moaned

He pulled down Johnny's waistband as a warm manly musk wafted into his nostrils. Geoff voice seemed to deepen as he lustfully bounced his pecs and moaned a low

“Fuuuooock..”

He pulled Johnny’s waistband more, revealing even more of Johnny's huge bush; soon leading to his massive cock, which flung upwards and pulsated hard.. towering over Geoff’s chiseled face.

Johnny looked down at his enormous pecs and thick hard abs with a look full of masculine filthy lust.

Geoff pushed his face against Johnny’s huge balls and began to suck and take deep whiffs that followed with low muffled moans

Their moans made a raunchy, dissonant harmony with Johnny’s deeper ones; they only got louder. Examiners walked by the enclosed room and heard the hot sounds, not batting an eye.

Geoff looked up at Johnny's chiseled, shredded torso, his massive chest heaving as he thrusted his hips and pushed his hard veiny cock deep into Geoff’s warm, tight throat.

The walls of Geoff’s throat stroked and hugged against Johnny's enormous hard-on, producing a deep squelching sound, mixed with Johnny's low grunts and moans.

Thick strings of goopy pre cum oozed down Geoff’s cleft chin; the squelching only getting faster and deeper as Johnny began pumping harder and quicker

Johnny began to feel the same indescribable feeling of deep masculine lust overtake him, the same sensation the growth fog gave him, he could’ve sworn his muscles began to swell and bulge bigger…

His core felt tight and his entire body swelled thicker, harder, his muscles pumping and swelling like a massive erection.. and it felt so fucking good.

Johnny’s eyes rolled back as he slowly threw his head back, his jaw appearing thicker than before. Geoff watched Johnny’s massive traps flare and his neck bulge as his enormous vascular growing muscle bod swelled and throbbed turning slightly red.

With one last low thrust, Johnny pushed his cock far down into Geoff’s throat, his massive nuts churned and arose pressing tightly against Geoff’s chin.

With a booming, powerful moan, the base of Johnny’s cock began to pulsate hard, pumping an enormous wad of thick lumpy muscle cum; Geoff could taste the potent flavor of masculinity and protein fill him up. A deep fwap and squelch resounded as Johnny had a few thrusts; the thick lumpy muscle custard now filling Geoff to the brim, squashing against Johnny's hulking cock as thick ropes of muscle cum oozed out.

Johnny flexed his enormous biceps as the hot smell of muscle sex filled the entire room. The smell of cum fumed and wafted up Johnny’s hard abs and pecs, filling his nose. He grinned and let out a pleasured moan, looming over Geoff.

“Fuuuck, that smells gooood..” he bulged even bigger

Johnny pulled out his enormous cock as Geoff began to swallow the dense protein load that filled his mouth. His slacks had a massive glob of cum from his enormous hard on.

The worship made Johnny even bigger than he was before. He was becoming a god, he could feel his first worshippers offering, feeding the horny beast in his belly; but he still hungered for more.

His thoughts were interrupted by Geoff’s huge, resounding cum burp, Johnny looked down at Geoff whose whole shirt was covered in muscle spunk.

He tried to stand up but was halted by something. His whole body tensed up

“You okay man?” Johnny asked

Geoff didn’t respond, but abruptly, his back began to rapidly swell, stuffing his shirt.

“Ohh, I’m more than okay..” Geoff’s said with a deep chuckle

--

Geoff erupted a long moan as he began to expand, widen, and harden with bulging solid muscle mass.

His tight buttoned shirt began to pop and rip a the seams, buttons began popping off one by one revealing a thick cobblestone valley of bulging hairy abs.

“FUUUUUUUCKK..” Geoff’s deep voice dropping an octave. His hunched over, growing muscle body trembling, feeling deep pleasurable sensations of raw power and masculinity.

Johnny watched Geoff grow as he slowly smiled. Proud of his unintentional result, Johnny started to feel like a true god. Bestowing such hot gains to Geoff; Johnny watched him writhe in pleasure as he arose to 6’2” slightly shorter than Johnny’s 6’ 9.”

Geoff had completely torn his shirt to shreds, his tight pants now shredded at the sides and struggling to contain his enormous bulge, his shoes bursted open revealing his massive feet. His bulging hairy pecs and and 10 pack abs were chiseled and beefy; Johnny could smell Geoff’s manliness fuming from his ripe hairy pits.

And he fucking loved it. Johnny had now found his dirty muscle bro.

--

“Fuuuck, this feels so good!” Geoff said; he looked down at his hard body, flexing his triceps, grunting deeply as he flexed and watched his muscles bulge big.

“Fuck yeah bro, you look insane.. look at those abs!” Johnny said as he watched Geoff flex for him.

Their excitement was quickly interrupted when a loud knock banged against the door.

They both had a moment of panic, the floor was covered in cum and the entire room reeked of man musk and hot muscle sex.

They knocked again

Their panic soon came to a halt when they both realized how massive they were.

They no longer needed to be weary of possibly being scolded. They were fucking muscle gods.

“Come in.” Johnny boomed.

The door opened, it was one of the examiners. He was quite buff himself but he was so small compared to the two gods that stood before him.

Johnny and Geoff could both tell he got a whiff of heavy muscle man stink. He stuttered in a low

“Oo- oh…”

As he entered the room more, his brows raised witnessing the chaos that had already happened. His eyes quickly looked at the messy floor covered in cum.

The two gods loomed over him, a shadow casted over the examiner as the massive muscle bros mass covered the fluorescent light. Both of their enormous cock bulges were at his shoulders, his eyes crept up their rippling cores to their enormous pecs and handsome grins.

“Dr. Atkinson?”

“Yeah Tony, it’s me. You like what you see?”

“Y-yeah but, what happened here?’” Tony looked around the cum covered floor. Johnny and Geoff hadn’t realized they trashed the room during their growing fit.

“And how did you get so big?” Tony kept staring at their massive rippling bodies that bulged in his face.

Geoff was about to explain until Johnny stepped in

“We’ll tell you everything if you can get Geoff and I into the growth chamber.”

“Oh, I can’t do that…” Tony said, he found himself staring at their massive size.. and fuck, it smelled so hot in the room. He felt their masculinity and dominance exuding over him. It made him feel horny. He wanted to help; he was also curious on how far this experiment could go.

Tony sighed

“But, I have another idea.”

--

After long talks between the examiners, they all agreed it was necessary to include Geoff in the experiment. They found it fascinating that Johnny’s cum produced such a drastic result for Geoff, causing hyper masculine behavior, and elevated testosterone levels.

Both Johnny and Geoff sat in their own day room. The couch was much smaller than their enormous tight bodies. They both sat with their legs spread wide, naturally bulging big. It was around 9pm and work in the facility had seemed to end.

Their door slowly opened, it was Tony. Geoff and Johnny sat up a bit.

“Hey Tony.” Their deep voices made Tony’s chest pound. He brought a large box full of huge bottles and set it down on a table in front of the two gods.

Tony smiled and breathed heavily from carrying that massive box.

“What’s this?” Johnny leaned over, his muscles rippling and bulging from the smallest movements, his large finger tugged the cardboard.

“Well, this form of growth treatment is being given to another participant, it’s a growth protein shake.”

“Fuck yeah, nice!” They both grabbed a jug

“I’m not sure about the side effects, so please. Just drink one.” Tony warned; he knew this was completely against the lab's plan. But, for some reason, he wanted to please Johnny and Geoff. He wanted to see them grow more.

Johnny and Geoff looked at each other, giving a shrug, they nodded; agreeing that they would both only have ONE.

“Enjoy guys.” Tony headed off and left the two muscle gods to their growth shakes.

Waiting a moment both the gods eagerly reached in the box grabbing one.

“Cheers man.” They both clunked their shakes together and slowly drank.

The protein shake was sweet and tasted like vanilla. It was good.

After guzzling some down, Johnny placed his drink down and released a massive, deep, guttural belch.

“Fuck yeah man.” Geoff grinned, rubbing Johnny’s rock hard 12 pack.

“Ooo..” Johnny moaned as he began to slowly swell bigger.. a look of euphoric pleasure glazed over his eyes.

“That felt good..” Johnny put his arm around Geoff as he took a big gulp of the growth shake.

They both heard Geoff’s stomach deeply gurgle as his abs began to tighten and ripple. He felt a deep powerful sensation overtake his entire body as he rapidly expanded and grew bigger. Their massive biceps were now pressing against their enormous pecs. The couch creaked and sank due to the immense weight of the growing muscle bros.

“Fuuuck..” Geoff moaned deeply, his face looked even more chiseled.

“Aw yeah man..” Johnny rumbled, he began flexing his enormous bicep. His diet face and chiseled jaw were now blanketed in stubble.

Both their shorts were now tenting as their cocks began to harden and make an enormous bulge between their wide spread legs.

Their massive hands began groping their own boners, rubbing each other's hard hairy growing muscles. Now chugging the rest of their growth shake.

They both erupted a gruff, thunderous, protein burp, relaxing on the struggling couch.

Their hard muscles began to seemingly joggle; suddenly expanding with monstrous amounts of hot, hairy, roid-like muscle.

“ooOOOHHH FUUOOOOCKkk!!” The gods moaned as both their shorts ripped; their lurching cocks began to jounce; the tip of Johnny’s pulsating cock head collected a thick glob of pre cum. Both of their hairy muscles pressed against each other, their enormous mass caused the couch to snap and break beneath them.

Their external obliques flared, their abs were so compact and deep they bulged creating a turtle shell-like shape. Their mega sized pecs were swollen and pushed forward, thrusting their hard nipples further down, pressing against their hard top row of abs.

A newly grown 7 foot tall Johnny stood up and flexed his massive back, his lats flared wide; he looked down past his massive 10 inch cock and low hanging churning balls to his enormous muscled legs. His enormous size made his face fill with obscene amounts of muscle lust, his tottering hard cock leaked a thick wad of pre cum.

Geoff stood up, placing his hands on his thick flaring Adonis belt, beside his massive 8 inch cock. He let out deep pleasured moans and murmurs; writhing in his manliness and power.

Everything was elevated. They looked at each other and quickly began to kiss. Their chiseled faces pushing their lips together. Filling each other's mouths with their big tongues.

They both moaned into the kiss, their cocks spurting globs of cum over each other's abs. The smell of hot spunk began wafting up their hard hairy pecs as they began to grind their hips hard, their eruptions thickening as dense warm ropes began to heavily squirt and splatter all over their pecs.

They both reeked of muscle nut and musk, and the floor now had a huge pile of muscle cum between them. Huge warm loads oozed over their rippling hard monstrous bodies. Loving what they’ve become, they both flexed for each other and filled their muscle stomachs by licking up the protein they pumped all over each other.

But it wasn’t enough. They only grew a bit. They needed… more.

Johnny and Geoff both glanced at the box full of growth shakes.

--

The next morning, Tony and the examiners arrived to check up on Johnny and Geoff. As soon as they opened the doors they were gone and so were the boxes.

Tony felt his heart thump hard in his chest. He stayed calm letting the other examiners try to figure out where they could have gone.

“Well we need to find them! What if they get into the chambers? Or worse, the protein shakes?” One of them exclaimed.

“Check the cameras.” The head scientist ordered; a few of the examiners scurried off to check the cameras.

“Come, we’re heading to the next floor.” The head scientist brought his assistant Tony and three other examiners.

--

Geoff and Johnny pounded in a long corridor, Geoff led the way, they soon arrived at a room, sealed by a large window.

The room contained a juggernaut sized muscle beast with a solid roid gut, beefy hairy pecs, and a thick nicely trimmed black beard; he looked familiar to Johnny.

“Diego?” Johnny's deep voice boomed. The man looked up and began to chuckle. A small speaker amplified his deep voice to them.

“Oooo.. they really made you a monster stud, huh?”

He stood up and lumbered towards them. His traps were bulging, he looked totally roided out. A swole fuckin muscle bull. His enormous bulge could barely be contained in his shorts. His room had buckets full of thick wads of cum, and a large catalog of bodybuilder magazines were stacked on the bent bed.

“Looks like they made you a swole bull yourself man.” Johnny grinned.

“And he’s been busy.” Geoff nodded to the cum buckets.

“Mmhmm, constantly horny, constantly wanting to grow more. Flex, fuck, and cum.” Diego chuckled.

Johnny and Geoff knew the feeling. They were five times bigger than before, their cocks were constantly bobbing with a hard on that got bigger with every flex.

“Do you know where Marco is?” Johnny asked

Diego pointed to an even larger room next to his.

Before they headed over Geoff typed in a code that opened Diego’s room. Johnny was hit with the powerful smell of muscle bull cum.

“Oo- oh fuck.. that’s good..” His muscles tightened and bulged thicker as he slightly grew before them. Marco and Geoff both moaned deeply as their cocks began to harden and their muscles began to swell a bit too.

“Shit.. that feels good.” Diego grunted doing a most muscular as his cock bulged even bigger in his shorts.

Johnny knew they were all on the verge of going into a growth fest, so he shifted his focus and led the way to the next room.

They all slowly walked towards the next room as their brows raised, their faces filled with shock. 

Marco’s deep moans sounded like pure bliss and filthy pleasure.

His hyper muscle pecs bulged and pressed up against the glass, his muscle abs tightly compacted into a thick 8 pack squeezing in between his enormous biceps. His gargantuan hard hyper-cock filled the small room, pulsating hard.

“Ohh.. fuuuckk.. it feels so good… I want mooooaaarrreee… fuuuuckk.. oooo..” his voice rumbled.

His chiseled hyper-masculine face was full of immense amounts of pleasure, his large hands rubbing himself.

Johnny, Geoff, and Diego watched with heavy amounts of lust. They could all feel a yearning to grow that big.. they wanted to grow even bigger than Marco. Supersede all expectations.

Geoff began to type the code but before he could finish all the examiners and security entered, halting their progressions.

“Stop right now!” The head scientist commanded. He was horrified by the obscene size and muscle.

“Do not open that chamber. Marco is extremely unstable right now.” He urged.

They all stopped before anything went too far.

Tony stared at their enormous bulging size with total muscle lust. Loving the hot horny gods he created.

Johnny could almost feel the hot lust exuding from the examiners.

He took a deep breathe as his massive muscles began to slowly expand

“Fuuuck.. you’re all so horny..” his ripped body began to rise taller… It was the perfect time for a growth fest. Johnny could feel their lust worship his enormous muscles. He was becoming the horny muscle deity he was meant to be.

Geoff quickly gave Diego a growth shake and they began to chug. Johnny's growing outburst was the perfect distraction. Johnny flexed both his enormous biceps that bulged high making the examiners and guards cocks instantly harden..

Some quickly backed away feeling cum pumping out of their cocks and stuffing their pants full, and others began to walk towards Johnny now rubbing, stroking, and humping his enormous growing muscles.

Johnny moaned and roared

“Yes!! YES!! WORSHIP ME!!”

Geoff typed in the code releasing the gargantuan muscle freak: Marco

With a symphony of deep resounding muscle burps that rumbled the entire corridor; Geoff and Diego began to swell and bulge bigger, elevating the examiner's lust and feeding Johnny's hot colossal gains.

Marco was at peak horniness, all the hot masculinity and muscle lust pushed him over the edge, he let out a long deep monotonous moan as his massive cock erupted a thick dense volley of hot muscle cum.

“Ooooooooo…. FUUUUUUUUUUOOOCK”

Thick globs of muscle spunk plopped on to the floor and began to pile and flood. Its potency and smell made the examiners and security guards knees unbuckle as their rock hard cocks began to erupt hard, producing huge volleys of cum in their pants.

Tony watched his co-workers kneel and cum before the massive muscle gods. He moaned as his cock throbbed hard, he needed more.

 Cum began to flood the entire hall as the three giant muscle gods began to push against the ceiling. Their enormous bulging mass now fills the vicinity.

10 feet, 20 feet, 30..

“Fuuuuuckk.. BIGGER..” The powerful giants moaned as the ceiling crumbled.

Tony was now on Johnny's enormous growing hairy abs protected by his massive looming pecs and extremely wide shoulders.

“MOOOORE.. FUCK YES!!!” Johnny roared, his voice deepened even lower, his gargantuan hairy pecs expanding wider, thicker and harder.

 

… the ground above the facility began to rumble …

… the sound of cracking, bubbling, and squelching grew louder…

 

Suddenly, Four mountainous sized gods smashed through, now above ground. Their colossal sized cocks all erupting dense, heavy ropes of hot growth inducing muscle cum.

A symphony of deep moans and sounds of masculine pleasure filled the atmosphere as the gods flexed for their new worshippers who climbed on their gigantic, powerful, god bodies.

Johnny's gigantic, solid core was the size of the other three's  giant muscle bodies. Tony was now ripped himself, stroking his hard cock on Johnny’s monstrous, hairy, giga pecs. Johnny flexed his veiny monster biceps, bulging them big beside Tony as he writhed and pumped load after load for Johnny, feeding him more.

The examiners and guards bursted out of their suits and lab coats revealing their new tight ripped bodies. Humping, fucking, and stroking on their gods even BIGGER muscle bods. Beneath them was a massive hot bath of thick lumpy muscle cum that bubbled deeply like a jacuzzi; a foggy cloud of hot muscle man musk wafted up causing an endless cycle of pleasurable growth for every single one of them.

Johnny's gargantuan cock arose high from the cum and began pumping like a fountain, flooding the thick cum bath.

The gods all moaned deeply, swelling larger as the thick cum bubbled against their hard freaky abs.

Their massive gigantic muscles bulged HARDER and continued to pump BIGGER, the worshippers grew with every orgasm, feeding their gods MORE pleasure and MORE growth.

An endless cycle began as the muscle gods reached peak masculinity and mass. Johnny looked down at the hot muscle mess he caused; and he loved it. He grunted and powerfully flexed a most muscular and double bicep as his cock simultaneously erupted even more thick, massive globs of muscle cum.

He continued to bask in his unending power, pleasuring and growing himself and the men who surrounded him and worshiped him.

But the horny beast within him still hungered for more.
