Chuck Smith had been coaching wrestling at Hudson University for the last fifteen years. His team had won several state championships during that time, and he was always being recruited for other colleges. Despite the large offers, he always had a soft spot for where he worked, which is why he could never accept them. Hell, he’d probably be there until the day he retired.

Coach Smith was no stranger to wrestling himself. He played in college, winning several local, state, and national awards. He wrestled competitively afterwards, before deciding to retire early and take a job coaching. Now in his mid-40s, his once lean body had filled out some. He didn’t have a ton of fat, but he had more of an off-season look, and less definition than he did during his glory days. He stood tall at 6’3”, and weighed around 265 pounds.

He was proud of his body, and he didn’t do too much to hide it. He always wore tight, white shorts that went about mid-thigh, showing off his hairy quads and calves. He wore high topped sneakers, size 13. He always wore his burgundy polo shirt, which hugged his chest and arms. Tufts of chest hair were always poking above his neck hole. He kept a trim dark mustache, and kept his dark hair short, though lately he had been sporting more of a salt and pepper look. It complimented him well, and he knew it.

Thanks to his winning teams, Coach Smith was always getting free sponsorships and samples from across the country. Even some of the bigger names in sports offered powders, supplements, pills, and shakes, but occasionally a start-up would try and work their product in. Last year a company had even offered to completely renovate the gym to help boost morale and support the team. It was a fortunate treat, seeing as the original gym was in need of a tune-up for years. One day, after practice had wrapped up, he got another package. It was fairly small in size, and looked completely ordinary. After a simple examination, he realized it didn’t have a return address. He took it to his office, and shut the door before sitting at his desk. Curious, he opened it up, and found a large bottle of pills, along with a note. It read:

“Coach Smith—You coached me several years back, and you never gave up on me, even when most coaches would. You pushed me to my limits, and I’ve been more successful than I could ever dream of, thanks to you. Here’s something that I did to pay it forward for someone else like me. Be careful, and start with just one; the effects may not last too long, but it will be worth it! Don’t take too many at once, though.”

It wasn’t signed. Coach wondered who it was. He had seen hundreds of students over the years. He always pushed all of them hard, and he couldn’t really identify who had sent it. As he was thinking about it, there came a knock on his door.

“Coach, you wanted to see me after practice?” The curious voice asked. Most people referred to him as ‘Coach’, instead of his full title since it was easier.

Coach Smith had completely forgotten. He had asked Josh Miller to stay behind after practice. Josh was new to the team, a transfer from another college. He was in decent shape, 6 feet tall and 175 pounds, but he was having trouble gaining muscle mass. No matter what he ate or how hard he worked out, he didn’t seem to gain or lose anything. But Coach had admired his determination, and wanted to work with him on a new diet. Even in their college years, it wasn’t at all uncommon for students to have high metabolisms. What mattered was finding a way to push through it.

“Sure son. Have a seat,” he remarked back. Josh sat down, still in his singlet.

“Now son,” Coach began, “I know you’ve been pushing yourself real hard in the gym. And I know you’ve been eating right and taking those supplements, right?” Josh nodded.

“Yeah, I’ve been following everything you’ve told me coach. I think I’ve hit a plateau though…” He looked down towards his feet. He started to think that he was about to get cut from the team. Coach Smith did want to cut him, but then he thought of that letter and the new supplements that came with it. He saw that look of dejection on Josh’s face and he felt bad for the young adult.

“Hey… tell you what, son. I just got something new in. I’m not sure how it works so I’m going to have some before my workout. I don’t want to give you something you’ll have a reaction to! Just be here at the same time tomorrow.” As he said that, he grabbed that unmarked bottle of pills, opened it, and swallowed one down with a gulp of water.

“Damn—thanks, coach!” Josh jumped out of his seat and reached his hand out to shake Coach’s. Coach reached out his own hand, but as he did, Josh swore that his big arm was even bigger than ever.

“Unghh…” Coach groaned, holding his head. His biceps flexed, tensing the polo shirt up. He felt warm all over and dizzy. “Something’s not right…”

Josh stepped back.

“Coach…?” He watched as he held his head, and then heard the sleeves strain further and further, until ripping entirely as the coach’s hairy biceps began to burst through. In just moments, hardly any fabric was left on his arms aside from a few small straps which screamed with tension. But it wasn’t just his arms, either. His traps started to rise up out of his polo, slightly lifting his shirt up from his waist. His chest swelled forward, making his buttons come undone. They pried off, one by one, slowly making their way down. There was a loud thud as his growing legs slammed into the sides of the metal desk.

“Fuck..what’s happening to me..??!” the coach bellowed, his voice was already beginning to become much deeper. He stood up, noticing that the ceiling was closer, and it was even getting harder to see the floor as his chest had grown so large that it filled the bottom of his vision. He watched in a mixture of awe and horror as the jock before him got smaller. He was afraid to admit it, but he even felt a flicker of arousal. Suddenly—


Coach’s shirt finally tore out in the sides as his shoulders and traps got too wide to hold it in. He grabbed the front of it and easily tore the scraps off his swelling body, exposing a set of thick growing pecs and a hairy set of abs he hadn’t had since college. Even so, these muscles were even bigger than the ones he sported in his glory days. His shorts were riding up so far as his thighs kept expanding. His ass filled out the back, the poor fabric whimpering, before his shorts too were in tatters, leaving him just in his jock and shoes. Even those were beginning to get tight as he realized his height was still expanding. Every moment, he was inching higher and higher, and all he could do was watch.

“Fuck Josh, go get the nurse or something! You shouldn’t be here!” he roared, his voice alone deep enough to vibrate his student’s chest. He sat there, heaving and breathing as he surveyed what had become of him. Just over the edge of his pillow-sized pecs, his eyes were drawn to his endowment. It sat average in size, but it looked much plumper than it had just moments before. He cupped his hands over his jock bulge. Almost as if reacting to the touch, his entire package began growing. At first he thought it was just becoming erect, but once it grew beyond that, there was no mistaking it. He could feel his cock growing longer and thicker. He tried to hide it with his hands, but the jockstrap continued to stretch lower and lower as he realized that his balls were swelling too. They rounded out, quickly surpassing the size of tennis balls as each testicle began spilling out the sides. His shaft began straining the stretchy fabric as he grew beyond 10 inches. 11 inches. 12 inches. In just moments, he was sporting one of the largest dicks on Earth. But the moment wasn’t over. It kept growing, quickly becoming too big as the jockstrap continued to pull down further and further. Since the pouch was not equipped to handle size of this scale, the straps on each side of his ripped thighs began stretching with it to allow just a bit more room.

As his length continued to swell, it pulled everything down enough to display his pubic region perfectly, alongside the first few inches of meat that extended down into an overflowing mound. Suddenly, it burst out of its confines, and slammed up against the top of his abs. It continued growing, pushing to more immense sizes as it throbbed against the underside of his pecs. With every heartbeat, it continued to swell. To thicken. It started to climb up the edge of his chest, the wispy hairs tickling it lightly. The coach shuddered, feeling how sensitive he had truly become as it brushed over the top of his nipples. The cockhead alone had the same circumference as a grapefruit.

Finally, there was one last thud as the coach hit the ceiling hard with his head. He winced and looked up in surprise, realizing that he must now be 11 feet tall, almost 5 feet taller than he was just moments ago, standing in his office completely naked with Josh staring up in awe before him. He’d been so caught up in the growth of his manhood that he hadn’t even realized how fast he was scaling up in height. His shoes were shreds that sat on the outsides of his feet. His socks were tatters of string. Any other clothes that remained on the ground was like confetti. He was panting heavily like he just got done with the most intense workout over, each muscle flexing and bulging with a deep soreness. His cock was harder than he could ever remember it being, and it was almost at his chin.

Josh could only look up in awe, not believing that his coach was now a giant of a man. He didn’t know whether to run out, or to worship the giant of a man before him.

When Coach Smith first started coaching, it was an open secret that he was gay. No one on the faculty or staff cared that much. Besides, he was a big guy to start with, and no one wanted to mess with him. On occasion, however, he did hear his students make nasty remarks about other gay students. He’d make them run around the gym for a half hour after practice for the rest of the semester as punishment.

He also never outwardly showed interest in his students. Sure he’d had some extremely attractive students over the years. Younger, bigger guys whose singlets left nothing to the imagination. But he never acted on it, and he was always quick to shoot down flirtations from them when they happened. He was good at keeping his sex life separate from his professional one.

Until today.

Now he stood 11 feet tall, with an enormous erection that reached up to his now thicker beard. Not only that, but his muscles put the hulk to shame. He couldn’t believe that in just minutes, he had grown so big. Big enough to be the largest human alive, with the largest muscles and cock to match. Maybe it was because of all the blood flow, but he felt lightheaded, and instantly started to stumble. His hands reached out and grabbed onto a metal bookcase in his office at the last second to steady himself. He was shocked when he heard and felt the metal crunch in his much larger hand. Just how strong was he? He shook his head, trying to rid himself of the confusion, when he noticed a blurred figure in front of him. That was when he remembered Josh.

He looked down. All he saw was his shelf-like pecs and massive rod, so he had to lean down even further to see him. He could see Josh’s face looking up at him. He looked afraid, but with a sense of admiration as well.

“Josh…” he said. He paused, though, becoming aware that his voice was rattling the windows, much deeper than he had been even when he was normal sized. “Josh… I don’t know what happened to me, but let’s try not to freak out okay? Maybe this is temporary, but I have to find some clothes. I can’t have you in here with my junk hanging out like this!”

Josh shook with both lust and fear as his coach spoke. Josh had always been into wrestling. He’d played a lot in high school, and he had family that were also into wrestling. But he had to admit, he didn’t mind being so close to so many bigger guys. Plenty of other guys on the team got hard during their practice, so no one really thought anything of it.

When he got to college, and saw Coach the first day he nearly lost it. He had lusted after plenty of big studs in the past, but Coach really made him hot. He would often stare at Coach, loving the way his polo hugged his thick pecs, and how his nipples always were visible. His powerful, hairy legs were always on full display thanks to those shorts he wore. His deep, commanding voice always got to him, too. He’d rubbed one out plenty of times to fantasies of his coach, getting naked in the shower with him, wrestling with him…

And now here he was, standing as a giant before him. He instantly got hard in his singlet. There was no way to hide it. And he couldn’t help letting out a low moan as Coach spoke to him.

When Coach told him to leave, he just stood there. He didn’t know what to do; half his mind was screaming at him to worship this new god before him while the other half was screaming for him to get the hell out, but lust won him over. He couldn’t help himself. He walked towards Coach, and he put a hand on his giant quad. It was like warm steel covered in hair, and was bigger around than Josh’s entire chest.

“Holy fuck, Coach, these quads are amazing!”

Coach looked down at Josh. He hadn’t suspected Josh was gay, let alone into muscle. He started fighting his own feelings. ‘I can’t let him be here’, he thought to himself. ‘If I get caught with a student my career is over. Then again, when they see what’s happened to me, I think my career will be over, too.’

But as Josh felt his quad, he shivered in delight. It was hot to him how small Josh’s hand felt on his thighs. He involuntarily flexed it, hearing Josh gasp as his thick leg bulged out even larger. His mind was too cloudy with lust at this point to care that Josh was inches away from his massive cock.

“C-coach? Do you mind if I feel the rest of you?” Josh asked. The coach laughed, a big booming laugh that shook his office again.

“Haha, all right, son. Don’t get too crazy now. Here, let me get down so you can reach better.” He got down on one knee so that his chest and arms were eye level with Josh. The student nearly came in his singlet as his big chest and massive arms came into view. It was just so big! When Josh was looking for ways to bulk up, he came across photoshopped pictures of bodybuilders, celebrities and other wrestlers. He had never seen anything like it before, and he had plenty of hot evenings looking at them. Now he had a living morph in front of him.

As Coach Smith knelt down, he noticed Josh’s rather large bulge in the crotch of his singlet. ‘Damn, so he’s enjoying this too.’ he thought to himself. ‘Well, I’m incredibly horny, so is he, and he knew since it was a Friday no one would be around.’ Again, he knew his lust was getting the better of him, but he wanted to show off his body just as badly as Josh wanted to feel it. He flexed up his right arm for him.

“Damn son. I used to be big back in the day, but I never thought in my wildest dreams I could be this huge!” he rumbled.

Josh reached up and grabbed his arm. It was so big around, there was no way he could fit both hands around it. His bicep and triceps were thick and hard, just like his thighs were. And his forearms made Popeye look like a wimp. He was certain that his biceps alone were larger than cannon balls.

“All right, son, I can tell you’re enjoying this as much as I am, so we’re gonna keep this our secret all right? Until we figure out a way to fix this, that is…” Josh nodded as he then moved his hands to his coach’s thick chest. It was unbelievably hard. A tundra of dense, thick hair covered it, and helped outline the sheer definition that sat on his frame. He ran his hands through it, slipping them over his nips. The coach let out a deep moan.

“Careful there, sport, these nips are hardwired and we don’t want an eruption in here do we?” he said with a wink.

“Coach… you’re so fucking big! How does it feel to be so huge?” Coach grunted, standing back back up to his full height, careful to hunch over some so as not to dent the ceiling again.

“Well son, I can tell ya, it does feel amazing. I’ve never felt so strong, so manly, just so big! It’s intoxicating, it’s definitely sent my testosterone into overdrive, I mean, look at this enormous cock!” He grabbed it with both hands, and even on his enormous body it looked huge. Even with his newfound size, his fingers were not able to fully encase the circumference of his thick cock. “It’s incredible! One of my previous students made these supplements. I guess they really worked!”

Josh looked up at his coach. Not only was he fascinated about his size, but he was also astonished that something existed that could make him so big. The pills! He looked over at the coach’s desk, and realized that they were still there. He thought about it. If he took one would he get as big as Coach? What if it was permanent? What if he got too big? What would his family and friends say?

He hesitated, but once again, he was so horny that he couldn’t think straight. Josh dove for the pills on the desk.

“Josh, wait! What are you doing! Don’t…!” Coach bellowed as he reached out for his student. But it was too late. He saw Josh swallow it down. A few moments of pure silence rang in the air as they both stood there. Not even five seconds had passed before Josh started to moan.

The effects that had slammed into Coach just minutes prior quickly overtook him. It started out with his arms thickening. In only seconds Josh’s arms went from slim to nicely defined. Noticeable muscles began packing onto them as they passed the size of a bodybuilder’s. All he could do was flex, watching as the mound on his arms grew larger and larger with every crook of his elbow. His shoulders and traps followed in his footsteps, pulling on the elastic of the straps that covered them as they started to make their own journey upwards.

“Mmmmmf, Coach, I’m about to become so fucking huge!” he coaxed. His words rang true as everything started to surge all at once. His pecs heaved out with enough force to pull the shoulder straps even thinner. The limited amount of spandex around his thighs started to show off the impressive definition in his quads as the striations of them grew more pronounced. Everything began elongating as well. His torso, his legs, his feet. Every bit of growth that impacted him had the side effect of stretching his singlet even tighter. Coach guessed that Josh had to be around 8 feet tall now, and sporting the musculature of a professional lifter. It was impressive seeing the growth from another angle, and Smith couldn’t deny how hot it was to see so much heft ballooning onto someone’s frame all at once.

The growth began to center itself around Josh’s package. It didn’t have the luxury of being in a simple jockstrap like Coach’s was, however. It was locked behind the fabric prison of his singlet, strained so tight that even his fingers would be unable to reach through the sides. His orbs rounded out. First they were the size of baseballs. Then softballs. Then, they surpassed beach balls! The bulge was so prominent that it hung nearly a foot off the front of the spandex, and that was before his cock started its mighty surge.

The structure of his outfit was looking comical now. Each web of string was now pushed to its limit. The red material that covered him was almost completely transparent now. Nothing was left to the imagination. Knowing that made Josh harder than ever. Pairing that with the growth that ensued called for an interesting combination. Unable to spread outwards any further, his cock started to scale the mountain of mass it was adhered to. It’s long, thickening form dragged along the clothing. His dick was so sensitive that his knees nearly buckled from the sensations that flooded him as the tissue-cloth that wrapped him teased the underside of his cockhead. Simultaneously, he felt stubble begin to appear on his face. In fact, hair was beginning to spread itself all across his body. It appeared most prominently on his face and chest, but it ran down his body and blanketed his arms, legs, and abs. His manhood used his treasure trail as a runway, following the symmetrical divot between his abs as it approached his pecs. The window of the singlet that typically sat above a person’s chest was pulled down so far that it did nothing to even hide his chest. It nearly showed off his abs! The thickening beast began to spill out the top as it grew and grew and grew.

Even if the effects of the pill were the same, the rate at which they happened was different. Josh’s head bumped the ceiling before his growth was even over. He hunched over, feeling his broadening back push down with him. As his upper body continued to swell, he watched in incredulous awe as his singlet impossibly contained him. The shoulder straps looked like spaghetti. It bunched up so much across his crotch that his balls spilled out of the last remaining space of his thighs, which stood like tree trunks. His shoes were a thought of the past.

Suddenly, everything that contained him gave way as the entire singlet practically exploded off at once. The sudden weight change as every muscle dropped towards the floor was enough to pull him against the desk for support, which now sat around his thighs. The bottle of pills clattered to the floor as the entire desk caved in from the sudden burst of weight. His balls dropped like anchors, slapping the interior of his kneecaps. Even at a standing position, his thighs grazed one another. Every individual muscle group was visible across his entire body, and it was hot as hell.

A short beard graced Josh’s face. The layer of hair that covered his entire body was prominent now. His size nearly rivaled that of Coach’s size. While his height was identical, his cock was smaller, but he was more gifted in other departments. His ass had rounded out more, creating the sexiest bubble butt on the planet. Seeing as Coach’s balls hung to his lower thighs, he noted that his balls had sunk down further as well.

“Fuck,” Coach said. No other words could be said. Both of them were lost in desire. Two hot muscle studs in the same room, with libido higher than anyone had ever thought possible. Muscle bulging to the max. Heads touching the ceiling. Cocks above their chests. Before any more conversation could be had, they made the small trek across the room and embraced in a tender, passionate kiss. Seeing as they were the same height, their lips aligned perfectly. Their necks had to reach forward a bit more than usual as their pecs touched first, their cocks frotting into one another just underneath their chins.

“You’re so fucking hot, Coach,” Josh remarked, sliding his hands up his hairy chest and giving his cock a nice stroke. Coach’s body jumped in response from the stimulation.

“Not too bad yourself,” Coach responded, using his knee to nudge his student’s balls, which seemed even more round and plump than just a minute before.

“What do you say we see what these muscles can do?” Coach asked, breaking the kiss and gesturing to the weight room just outside the office door. Josh’s gaze looked back at him, filled to the brim with excitement. Both of them could see it in each other’s eyes. The lust and greed that filled them. The desire for…more.

Coach winked, snatching up the bottle of pills and leading the way. Josh watched as Coach tried his hardest to squeeze through the normal door. The frame of it only sat at 7 feet tall, meaning that he had to bend down 4 feet just to wiggle through. That would’ve been pretty simple if it weren’t for the hundreds of extra pounds of muscle that had spread across his body. The shoulders of this man were far too broad to get through, each overlapping the doorframe by multiple inches. Instead, he turned sideways, threading his cock out just before his huge chest and globe-like ass began grinding into the edges of the metal that encompassed him.

“Come on! Just…a little..more!” he grunted, pushing forward with all of his might.


The door frame bent outwards, the flexing of his body alone causing enough tension on it to allow for more space. A small gust of wind rushed around the big human as the near-air-tight seal broke through. He stumbled onto the other side, breathing a sigh of relief as his muscles relaxed again. He looked around, taking note that nobody else was around. This was to be expected, as it was after class on a Friday.

“All right, Josh. Your turn,” Coach said enthusiastically. Josh walked up to the door. The hinges were bent backwards. This door would definitely never close again. Since Coach had already paved the way for him, squeezing through the gap was much easier. It was almost like a game of ‘Hole in the Wall’.

Coach reached a hand out, helping guide his student through the rest of the metal obstacle before they were both finally in the weight room. The weight room was much larger in comparison. While they were in a cramped office before, now they had a room that was the size of an entire classroom. The ceiling was slightly above their heads, coming in at around 14 feet.

Without wasting any time, Coach set down the pills and picked up the nearest weight he could find. A 25 pound plate. The ease at which it was able to be picked up was impressive. He clasped the edges like a steering wheel and tightened his grip.


The metal groaned. Josh felt a bit of precum run out of his manhood at the hot visual of Coach’s muscles bulging even bigger as he bent the weight with ease. It folded almost completely in half, only a crescent of the circumference it had been. Instantly, it was like a game. They walked around, grabbing the largest things they could to test their strength. Josh grabbed a barbell, effortlessly warping it into the shape of a tree branch, as Coach positioned another plate between his palm and his right bicep. He did a curl, his eyes welling up with a fiery passion as it crumpled against his skin.

“Ha! Easy, Coach,” Josh proclaimed proudly.

“Fuck yeah! This was too,” he said, tossing away the second plate. “We’re Bulls! That size looks good on you…” The feeling of excitement that was brewing in the air was too much. Coach couldn’t restrain himself any longer.

“C’mere, stud. Let’s do some real wrestling,” he said seducingly as he tackled Josh back onto the matts that covered the floor.

“Fuck wrestling! Come here, coach.” One of Josh’s hands grabbed the back of Coach’s head, pulling him into another kiss. It started another frenzy of making out, but this time it was even more erotic. The other hand felt the ridges of muscle that covered his back. Their breathing was hot and heavy, but things were still heating up even more. Both of their cocks were pooling precum onto each other’s chests. Sweat dripped off of their hairy bodies as their legs intertwined. Josh broke the kiss.

“I want you to fuck me, Coach.” They were far too lost in the moment to even care about the setting they were in. Josh stood up and braced himself against a weight rack for support as he leaned forward, revealing his hole. Coach took advantage of the moment, his cock easily sliding in from the sheer amount of pre that covered it. A moan instantly forced itself out of the teacher’s throat.

“Your ass is so tight. It feels so good wrapped around my cock,” he said, his breathing shuddering as he slowly started to pick up the pace. He slid back and forth, enjoying the view of Josh’s muscles tensing and relaxing with every thrust. The coach’s balls slapped against his ass over and over again as the student’s own balls vibrated with joy around his knees. Both of them were moaning now, unable to control themselves as pleasure pulled them down even deeper.

“Fuck, coach! I want to cum so bad,” Josh said as he looked at his hands. The weight rack was bending under his iron grip. His own dick was practically adhered to him, so hard that it still sat against the underside of his chest. He enjoyed the sight of it, watching as it poured more and more liquid as the intensity spiked. That was when he noticed something peculiar. It looked bigger. In fact, it was looking much bigger. While his cock had been up to the top of his chest before, now it was nearly up to his collarbone!

“Wait, my cock…it’s getting bigger!” Josh screamed. Coach paused for a moment, a smile growing across his face as he knew what needed to happen next. With no break, he switched him into a different position while still inside of him, grabbing the weight bench that was just within reach. Coach flipped him onto his back, holding Josh’s legs in the sky with his hands firmly clasped around his calves. Hearing that he was growing was only motivation for Coach to fuck him even faster, and he wanted to watch.

The sounds that left Josh were beyond moaning at this point. It was yelling. At the angle he was at, his balls pooled around his taint and thighs. His cock sat just within mouth’s reach. He reached his tongue out, swirling it around his sensitive cockhead as it felt it continue to grow. It lengthened further, brushing against his soft beard as it surpassed his lips.

“It’s not stopping! It keeps growing! Please let me cum, coach, please!” he begged.

“Just a little bit more, son. I want to see how big we get it. Hold on,” Coach urged.

Josh watched as the fluorescent lights above him began to become blotted out as his cock loomed over his head. The tip of it climbed from above his nose, to his eyes, and then up to his hairline! His hands stayed firm on the shaft of his cock, feeling his fingers force themselves apart even more than as it thickened.

“Fuck, Coach! I want your load in my ass so bad!” he yelled, feeling an overwhelming sense of pressure begin to build from within. Seeing so much growth pack onto Josh’s manhood while he fucked one of the hottest asses he had ever seen was enough to bring him very close as well. He doubled down, giving the longest, sexiest thrusts he could muster as inch after inch forced itself down Josh’s length.

Ahhh. Can’t hold back. I’m cumming!” Josh roared. Instantly, load after load of thick, white cum sprayed against the wall behind him. Each burst was as thick as a water bottle and coated everything. His mouth hung open as it grew taller than him. Every rope of cum just made him bigger and bigger.

The visual of Josh’s own cockhead growing larger than Josh’s entire head, as it grew up taller than him in height sent Coach over the edge. His own breath grew raggedy as he gave a few final affirming thrusts as his own load blew. Both of them were in a constant stream of moans as they exploded with an impossible amount of seed. Coach’s ears began to ring as he grew slightly light headed from the amount of blood that flowed to his cock. His mouth hung open as he felt the waves begin to calm. Both of them gasped for air, sweat pouring profusely off of their bulging frames as they collapsed backwards, somehow an incalculable amount of energy still brewing within. They embraced each other, somehow still impossibly hard.

“Whew! Big muscles and big loads,” Coach said, giving a deep laugh.

“Yeah, coach! Never thought I’d get this big!” Josh laughed back.

“Want more?” Coach said, giving a slight nudge against his shoulder.

“Hell, yes!” Josh said back enchantedly.

Both of them went for the pill bottle at once. Josh ran over to the little bench that Coach had set it on, moving awkwardly due to the new amount of muscle and manhood that covered him. Coach was right on his heels. Just before he could grab it, Josh snatched it up and dumped another pill in his mouth.

“Sorry, Coach! My turn to go first this time!” he said unapologetically. The effects were immediate, just as before.

“Yes. Yes! Grow!!” He flexed his biceps, watching as they started to bunch up even bigger. Size started to ripple up and down his frame at a worrying rate as Coach took a step back in surprise. The sounds of growth became very apparent as Josh widened his stance. The V shape of his body grew more pronounced as his shoulders punched out even wider and his lats flared out like wings that further connected his arms to his chest.

Veins started to wind around his body like a snake under a blanket, each thicker than pencils. His head bumped into the fluorescent lights as he took another step forward. If his biceps were the size of cannon balls before, they were surely now even larger than the size of basketballs! His chest looked like two wine barrels had been fixed onto them.

Ahhhhhhh—!” Josh screamed, his voice growing even deeper as he smashed into the ceiling. The walls shook with the power of his vocals. Debris showered down into the gym as he started to grow up and out. His quads widened more and more, thickening even faster than his own legs were growing. They were almost incomprehensible compared to the size they were before, now almost holding the same circumference as Coach! He winded his arms up, knocking a large section of the roof out above them as Coach had to crane his neck higher and higher to keep him in view. He was now only eye-level with the bottom of his shaft!

“Hey, Coach! You’re looking kinda small down there!” Josh teased.

“Small?! Watch this!” Coach scoffed. He dropped a few pills into his mouth this time, not even caring anymore about what would happen. It seemed Josh held onto a pill or two of his own, and he knocked those back as well.

Coach gasped, feeling a rush of energy that felt impractical. He could feel his heart skip a beat as he realized the consequences his actions were about to have. Part of him was nervous, but most of him was excited.

It felt like he was punched. Size started packing on so intensely that all he could was inhale, unable to close his mouth from the pleasure that ensued. Coach looked down as his chest doubled in seconds, pulling him forward until he was up against Josh. His height surged, every part of him broadening as hundreds, if not thousands of pounds tried to suffocate their way onto his frame. Coach’s eye level went from Josh’s thighs, to his abs, and then to his chest. His arms exploded outwards, crashing through the ceiling. He felt it pry away even more to accommodate him as he continued to grow up and up.

Fuck yeah!!!” Coach roared, enjoying the euphoria as he passed Josh in height entirely. His arms billowed out to the size of smart cars as he flexed them as tight as he could. The entire upper half of his body now protruded from the weight room. His cock stood like a spire, elongating more and more as it grew up past his eyes. It throbbed with enough power to send small vibrations through the ground. He felt his own balls descending, but he couldn’t tell how much over the size of his massive pecs.

“Who’s the small one now, son?” Coach teased back.

The growth continued through both of them, their bodies molding into the likeness of statues as they stepped out of the rubble. Movement at that scale proved to be very odd, especially now that Coach could feel his balls even lower than his knee caps now. The entire gym folded inwards, collapsing in a heap. Coach mentally patted himself on the back as he remembered he was still holding the pill bottle in his hand.

The effects of Josh’s pills caught up. Coach watched as his growth leveled off with his own, making them near identical heights again. Even still, Coach’s cock was nearly a foot above his head. Josh’s cock was multiple feet above. Both of them glistened in the afternoon light as pre pumped out of both of their shafts.

The sounds of moaning, destruction, and muscles growing caught the attention of all the bystanders. Some ran. Some watched in shock. Some couldn’t help but start jacking themselves off on the spot. From their height of over 35 feet, they could barely hear the comments that were being made, but the commotion was obvious. They were two giants who had just hulked out of the building! The comments flew across the yard like crazy. A lot of them happened to be his own students.


“Is that—Coach??”

“And the other guy—?”

The remarks warmed up Coach’s heart, while also making him throb harder. The statements were really getting to him.

“Ha!! Sorry to interrupt your practice, little men,” Coach rumbled down. His fellow students looked up at him in awe.

“Coach!! How’d you get so fuckin’ big?”

“Am I dreaming? They’re giants!”

Bro! You’re a monster!”

“Fuck! Those cocks!”

They ran up to the feet of the giants, admiring their beauty as they tried to get as close as possible for a better view.

‘If they want a better view, I’ll give it to them,’ Coach thought. “Got some new training for ya! You’re going to work on our muscles,” he commanded.

He reached down as much as his body allowed him to, picking up one of the students and placing them across his body. One hopped off on his biceps, which was even larger than those hamster balls that humans could go into. Two others started to scale his chest like a rock climbing wall. Even with their hands hanging onto the crevice of his collar bone, their feet only hung down to his nipples.

“You like that?” Coach teased.

“Yes, Coach! Let me worship you!” one of them chimed back, hugging tightly on his arms.

Josh picked up a few people of his own, placing two of them on his cock, as the others sat on his shoulders. Overall, their bodies were actually fairly proportional compared to their heights, but that would quickly change with what was to come.

The effects of so many pills were still racing through Coach’s body. A hot feeling coursed through every muscle as he began to vibrate with desire. The humans worshiped him. Licking him. Rubbing him. Pumping their cocks on him. Every comment only ceased in chubbing him up more and more.

“Coach, you’re so huge! Muscles like mountains!

“I’m cumming!”

“Fuck, you’re so monstrous!”

“Coach, your cock is like an oak tree!”

Coach couldn’t contain it any more. It was too much!

Fuuuuck! Your worship is making me grow!” he thundered.

Muscle slammed like a train into Coach. To say he was swole before was an understatement. He flexed his arms into a double bi-pose, watching as those rose the size of a three-story building! They very quickly started to rub into his chest, each pec growing even larger than a house! He felt them grow and grow and grow, until they started to push into his chin. It was hard to even look down anymore, both from how big they were and from how far out they extended! His beard grew even longer as his hair wisped around more heavily. It was like every time he stopped flexing, every bit of size completely retained itself! The people that were hanging onto him clutched even tighter, feeling as their hand-holds grew even deeper, their own bodies lifting higher and higher on his musculature. His traps bloated upwards, starting to heavily climb up his neck. The worship continued.

“Fuck yes!! More mass!! Thicker!!”

“God, Coach! I could get lost in your traps!”

“Grow, Coach!! More! More!!”

The shadows of his frame grew across the field as the trees started to pale in comparison. The striations that covered his muscles became extraordinarily pronounced. His broadening width started to pass into morph territory. And then beyond. Unnatural. Just mountains of muscle that only had one goal in mind. Grow.

Even in contrast to one muscle group, the humans that scaled Coach looked smaller and smaller. His forearms blasted outwards, so thick around that it would take 3 humans laying across them just to reach from one end to the other at its thickest point. The veins that rolled through them rivaled the thickness of telephone poles. Even centurion trees couldn’t even balance half of the width of his calves. In fact, an entire train car couldn’t even reach from one side of his thighs to the other. Both of them crashed into each other with every moment, causing a minor hindrance to his mobility.

“Your cock is so huge!”

“God, with balls like that, how could a bull like you ever rest?”

Grow that dick even bigger! No, bigger!!”

It seems that the best part was saved for last. The comments mixed with the growth caused for a massive surge of bliss to spike through his manhood. Coach’s voice boomed with so much pleasure that his worshipers had to cover their ears.

Cum soared through his monolithic package, piercing the sky like white rain, only much thicker. While you would think that such an explosion would cause his balls to grow smaller, they did the opposite. They rolled down his vast expanse, bloating and gurgling as they passed his calves. Then his shins. Then his ankles. Each sphere alone easily covered the entire gym that was standing only minutes prior. His cock grew as well, swelling like the largest air pump in history was attached to it.

Fuuuuck, I’m huge!” Coach gloated.

Josh could only stare with eyes the size of dinner plates at what was unfolding in front of him. Coach’s cock alone nearly doubled the girth of his own now and was even larger around than his chest! In fact, even his muscle groups were so much more expansive.

“Coach! So much mass—” Josh got cut off.

“And still growing! You wanna be like me, son? Grab me and grow,” Coach offered. Josh extended a hand, grasping Coach’s cumming shaft as the power instantly shattered throughout Josh as well. Not even a second passed between making contact before Josh started cumming uncontrollably. Size blasted up throughout his body at an absurd rate that even Coach could feel in his chest. Everything that had just happened to Coach was happening to Josh now.

Coach’s power while cumming fueled all of it. Their proportionality and size was beginning to rival each other’s. Both of their cocks bucked wildly, moans spreading across the region as the sound of muscle expanding grew louder. It was like balloons rubbing against each other and then pitched down. His own prick extended higher and higher and higher, moving from just a few feet beyond his head to multiple! It was as thick and juicy as ever, nearly 30% higher than his head over anything else!

“Oh, man! What a rush!” Josh exclaimed! “We did it, Coach! We’re gods!” They were both able to acknowledge how much of an amazing feeling it was being so colossal. The gym below didn’t even reach up to their calves! They were easily more than 100 feet tall. Absolute giants compared to everything and everyone. There was no doubt that people for multiple miles around knew of the events that were transpiring at the school.

“How do you like us now, little men?” Coach relished, flexing his huge arms to even more preposterous sizes.

“Worship us!!” Josh boomed, giving his own flexing pose as well. Those that had stayed were there for good.

“We love you!!”

“Yes, Master!”

“Fuck, you guys are so hot!”

Coach looked down in his hand, noticing that he still had a good hold on the tiny pill bottle. Ironically, the entire capsule now looked even smaller than the pill they originally ingested. Part of him wanted to throw it back and down the entire thing, just to see what would happen, but logic won. There would be time to try more later. Besides, at the size they were, they could enjoy this for quite some time, and there were still tons left. The instructions stated that the effects didn’t last too long, so it’d be best to ration them.

Coach looked back at Josh, who was flexing in many ways. Both of their cocks were still rock-hard, leaking enough cum to make a stream that pooled on the ground around their feet. Much of the surrounding area was completely coated in the copious amounts of seed they had each expelled. All of their remaining worshipers continued their duty, still safe atop their muscles. Coach’s balls scraped the blades of grass below, while Josh’s hung to his ankles.

“Hey, stud,” Coach started.

“Yes, Coach?” Josh replied erotically.

“Since this size doesn’t last forever, what do you say we maximize our pleasure?”

Josh didn’t even have to say a word. All he had to do was turn his body and open his arms. Coach smirked. He gripped the pill bottle tighter, knowing not to lose it for when it would come in handy again. With that, he approached his massive student to give him the fucking of a lifetime.
