H2Grow: Just add water

by Musclesaber   

Commission done for @scot158f on Twitter/X. Tony is off to his first day of college and finds he’s been paired with a science geek as his new roommate. What could go wrong when he’s doing experiments in their room all the time?

Move-in Day!

Tony climbed the stairs to his second-floor dorm room with bags of luggage in hand. Groaning with each step, the stocky man finally reached his door and fumbled to get the key out of his pocket. As he did this, he started to lose his grip on all of his bags. Trying his best to fish the key out of his pocket, Tony at last grabbed the key, but his hand couldn’t hold on any longer. All of his bags fell to the ground with a loud crash and Tony sighed in defeat.

While Tony was picking up his dropped luggage, the door to his room swung open. Tony looked up from the ground to see a tall lanky guy standing in the doorway. “Hi there! You must be Tony,” said the stranger with a smile on his face as he reached his hand out to Tony.

“Yes I am! And you must be Andrew. Nice to meet you.” Tony got up from the ground and reached his hand out to meet Andrew’s in the process of dropping all his luggage again.

“Need some help with that?” asked Andrew chuckling a bit at Tony.

“Actually, yeah. That would be real helpful man,” said Tony, picking up some of the suitcases. Andrew got down and started to collect a few of Tony’s bags and walked back into the room.

Tony followed him in with the remaining bags and examined his new dorm. On his side of the room, there was nothing. A blank billboard and a twin sized bed attached to a desk with a chest of drawers and a small closet. On the other side, it was clear that Andrew had been here well in advance and set up his room. He had plenty of Star Wars, Marvel, Lord of the Rings, and Star Trek posters up on the wall. Along with stacks of books on his desk and plants lining the window sill.

“Wow, you didn’t waste any time moving in,” said Tony, setting his luggage down in front of his closet.

“This isn’t my first rodeo. I lived in this room last semester. In the fall semester, I was in this room by myself. I think I originally had another roommate, but he ended up dropping out either right before the semester started or the first day of classes because I never met him. So I had this room all to myself last year,” said Andrew. Tony started to move his luggage into the room and while doing so, slinging some of his suitcases up onto the bed.

“Oh, nice man. Sorry to ruin your solo act,” said Tony.

“It’s okay. It’ll be nice living with someone. Did you have anything else that you were gonna bring up? I can help you out if you need it,” said Andrew.

“Nope, I wanted to bring everything up here in one trip. But I’m pretty beat from that drive.” Tony took off his jacket and set it on his desk and then laid down on the bed. Andrew quickly stood up and walked over to Tony.

“Oh, well maybe, if you don’t feel like unpacking now, we can go and get some food? Ya know, get to know each other. We will be living with each other for the next four or five months, might as well start it off right,” said Andrew as he started putting on his jacket.

“Yeah, sure. Just let me get a quick break in then I’d be more than happy to get some grub with you,” Tony smiled at Andrew and Andrew gave a big toothy grin back at Tony.

“Great! I’m just gonna run to the bathroom real quick and then we can leave,” said Andrew as he opened the door to their room to go to the community bathroom they shared with the whole floor.

Tony looked over at his luggage on the other side of the bed. He leaned forward and grabbed one of the zippers on the bigger suitcases sitting on top and quickly unzipped it. Sitting on top was a big fluffy pillow with folded sheets below it. Tony grabbed out the sheetless pillow, put it on the side he would put his head, and laid down. He took a deep breath in and sighed from exhaustion. But he paused for a moment.

What is that smell? he thought to himself. He sat up and grabbed his pillow and moved it out of the way. On the mattress was a small stain that looked to be no bigger than a ping pong ball. Looks like whoever had this bed last was not the cleanest roommate in the world. I’ll have to get some candles or something to get that smell out of here.

As Tony was examining the stain on the bed, the door swung open and in walked Andrew. “You ready to go or do you need some more time to rest?” asked Andrew as he reentered the room.

“Yeah, I’m good to go. And maybe we can leave the window open or something. My bed kinda reeks,” said Tony as he started standing up. Andrew’s eyes got wide for a split second, but then settled back into his big smile.

“Oh yeah. Sorry about that. I think it’s my experiment going on over here.” Andrew walked over to the windowsill where he had five potted plants lined up. “I’m a biochemistry student and I really got to know one of my professors last semesters so he let me do a little experiment of my own over winter break. I won’t be winning the Nobel Peace Prize for it or anything, but it’s still a good way to get close with the professors in my major.” Andrew grabbed a spray bottle sitting on his desk and started to spray the plants with water.

“That sounds interesting. What are you testing?” asked Tony as he got up and stood next to Andrew.

“These plants were given a fertilizer that was supposed to give them more nutrients which would enable more growth output. It won’t grow them massive, but I’m seeing which chemical combination reacts the best to inhibit the most growth. Long term it could give farmers a new product to get bigger harvests every season.”

“Wow, that sounds…really complicated, but also cool,” said Tony. He leaned in towards one of the plants growing and took a sniff. “Ooo yeah. That’s what I smell.” Tony grabbed his nose a little bit and stepped back towards the door.

“Sorry, this fertilizer is fresh. I didn’t realize you were moving in today and put it on the plants. It will smell for a little bit as the nutrients work their way into the plant’s system. That’s why I suggested we go eat and get out of the room while the smell goes away,” said Andrew, putting his spray bottle back on his desk.

“I see your point. Then lead the way to the nearest dining hall. I don’t think I realized how hungry I was until I was out of the car.” Tony opened up the door and waited for his lanky roommate to walk out with him. Andrew smiled and followed Tony out of the room towards the nearest dining hall.

A few hours later

“I can’t believe they allow All You Can Eat at The Market on Saturdays. That’s gonna save me sooooo much money this year,” said Tony as he walked back into his dorm room with Andrew.

“It’s pretty nice. And for a growing guy like you, I’m sure you’ll take full advantage of it.” The two laughed and looked at Tony’s bed. It still had plenty of still packed suitcases sitting on it.

“Damn I’m not looking forward to unpacking that,” said Tony as he started unzipping his suitcase. Both of them were happy that the smell of the room had returned to normal and they weren’t suffering through the stench of the fertilizer.

“It’ll be done before you know it.” Andrew sat on his bed and started to play on his phone. “If you need any help doing any of the heavy lifting, I know I don’t have much size to show, but I can at least help.” Andrew brought his arm up and flexed his mediocre bicep for Andrew.

“Thanks Andrew. But I don’t think I have much to unpack. Mainly just clothes and some supplies for school. It’ll just be a pain.” Tony started unpacking his things as Andrew got up from his bed and checked on his plants. “Did the plants like the fertilizer you gave them?”

“Unclear. I can’t see any changes in them now, but it has only been a few hours since I added the stuff. Realistically, I shouldn’t see any real changes for a few weeks,” said Andrew as he continued to examine the plants.

“So how does all of that stuff work? I’ve never really been big on science, but I’m always open to hear of better ways to get bigger,” said Tony as he started putting some of his clothes away.

“It’s kind of complicated. How much do you know about biology? Or chemistry?” asked Andrew, spraying down the plants with water.

“I’m a kinesiology major so I know about biology. But that’s human biology. Not plants.” said Tony, folding up some shorts and putting them in his dresser.

“In layman’s terms, whenever I give the plant water, it should activate the nutrients in the fertilizer I gave to the test plant to inhibit growth. But the growth we see at this stage would be microscopic at this early of a time. Or at least on this size of plant. But if we wake up in a jungle of vines, we know it worked.” Andrew got out a ruler and notepad and started to jot down numbers on it.

“So could it work on humans?” asked Tony, peering over Andrew’s shoulder at the plants.

“Who knows? All of this is theoretical. Don’t get me wrong, professor Hendricks and I have been running the numbers and these plants should only grow a few inches more than a regular one. But we’ve only ever tried it on plants. I don’t even know what would happen if that fertilizer got into a human’s system.” Tony frowned and walked back to his closet and continued to hang up his clothes.

“Well, whenever you guys do human trials, let me know. I’ll be first in line. I’d do anything to grow.”

“Yeah I feel you there. I might not be as short as you, but being as skinny as a twig sometimes can be a pain. People always say I look like a giraffe.”

“Short and fat isn’t the best either. In the last few months, everybody has been calling me a baked bean.”

“Wow, that’s rough buddy,” said Andrew as he walked back to his bed. “But kinda funny.” Andrew couldn’t hide the small smirk on his face. “You’ll be able to go to the rec 24/7 if you’re trying to get buff big guy. And the kinesiology department is right next door so it’s an easy commute to class.”

“You’re right, but I was always the short kid in high school. I never was strong enough or fast enough or tall enough to be in any sport so I was really hoping that I could at least gain some sort of size in college,” said Tony.

“I was a band nerd. I didn’t care for any sort of sport. They’re overrated in my opinion. But considering the rec is free with tuition, and as we learned tonight, Saturdays are all you can eat, you’ll get big in no time. At least in the muscle department. The height department, I’ll give you a call once we’ve figured out how to grow people taller,” said Andrew as put away the last of his clothes.

“Like I said, first in line for it.” Tony plopped himself down on his now made bed and breathed out a sigh of relief. “Finally done. I’m beat.” Tony took another deep breath in and then caught a whiff of himself. “You know, on second thought, I might go shower and then head straight to bed. All that moving today really took it out of me,” said Tony sitting back up and grabbing his towel and toiletries.

“I’ll be here. Have fun. Make friends,” said Andrew.

“Make friends? It’s the floor’s community bathroom. I don’t know if I wanna make friends in there.”

“Hey, you never know,” laughed Andrew as Tony shut the door to head to the bathroom. Tony turned the corner and entered the community bathroom. It had three stalls with toilets and three stalls for showers. Tony ducked down and checked if anyone was in there with him, and to his luck, there was no one else. He opened the first door to the shower stall and stepped in .The stall wasn’t very big. It just had a dry area for Tony to place his pajamas and then the small shower itself.

Tony walked into the shower and turned the water on. He started rinsing off his body. Taking stock of it, there wasn’t much to rinse. Andrew hadn’t been lying. Tony was a bit of a little guy. At only 5’5, he definitely was towered over by most other men. And even some women. And he was pretty stocky for being so short. He rinsed off his sizable moobs and lifted his belly up so water could get the undercarriage. Looking down at his belly, he couldn’t even see his stump of a dick under it. At only 3 inches, Tony really longed for any size at all.

Tony sighed as he reached for his shampoo bottle and started lathering up his curly black hair. Tony was met with a weird tightening sensation on the back of his head when he started to rub the shampoo in. It wasn’t burning him, but he did feel a strangle warmth trickle across his head and down his neck. Tony pulled his shoulders back as he felt the warmth spread throughout his whole body. His toes curled as his back arched up. He was lucky he was alone because he let out a deep, loud moan. It echoed through the stalls of the bathroom and Tony felt it ringing through his chest.

It started in Tony’s shoulders first. It was subtle, but he could feel them thickening. His traps became denser and his delts rounded out. Spreading out to his flabby arms, the jiggly fat that hung on his arms seemed to be moving and shifting. Tony was shocked when he flexed, he saw his biceps inflating to the size of softballs. Tony balled his hands into fists to see the veins pulsing on his vascular forearms. Seeping down to his chest, his moobs began to plump up. The once saggy moobs were pushing upwards on his chest. Forming a rectangular shape on his chest and filling out with more muscle. His belly felt like it was marinating with the warmth. Tony rubbed his belly and let out a loud belch that echoed throughout the entire bathroom.

Tony moaned again and gripped his cock with both of his hands. His eyes shot open and he looked down to see his cock. He could see his cock and grip it with two hands. Tony smiled in disbelief as he felt his cock pulse in his hands. His spine shivered with every heartbeat as his cock throbbed bigger and bigger. Tony felt his already somewhat fat ass tighten up and form into a bubble butt behind him. Thunder thighs shaping into ham sized quads. He raised his toe up and flexed his diamond calves.

As Tony stayed under the shower head, he felt his body start to go through a different change. He had gained some muscle suddenly, but now it seemed his belly wanted to grow bigger too. Tony let out another large belch that lasted a few seconds and then he gripped his stomach. His hands were feeling pushback as the belly began to push out further and further. Looking at his body, he saw the toned muscles begin to swell with fat. His athletic build he had just gained being eclipsed as fat began to crawl back onto his body.

Tony reached for the shower faucet and turned the water off. He looked down at his body and was amazed. He couldn’t help but grope and prod at his new form. While he maintained a rather full belly and a significant amount of fat still on him, he could actually see muscles on him now. “I knew there was muscle under all that fat,” mused Tony. He couldn’t stop smiling as he began to towel off his muscular body.

Pulling up the pajamas he had brought, his underwear felt tight on his beefier body. Gripping the waistband, Tony heaved them up and over his fat ass that now felt shaped more like a bubble butt than a lumpy blob. His legs felt squeezed into the pants like sausages and his calves and ankles were on display at the bottom of the pants. Pulling on his shirt, his sleeves felt constraining around his biceps and like one little flex could tear it. His hairy belly was now on full display for the world to see since now his shirt only covered just above his belly button.

Walking out of the stall and staring at himself in the mirror, Tony couldn’t help but smile with glee as he looked absolutely comical now. He didn’t know how it happened, but he had gotten bigger. His clothes looked two sizes too small at least and he had no idea what happened. But he didn’t care. All he did care about was that he had done what he had never thought was possible. Get bigger.

He walked giddily back to his room and entered to see Andrew playing a video game on his tv. Andrew looked up and did a double take at Tony. He squinted his eyes and paused his game. “Hey Tony, how was your shower?” asked Andrew skeptically.

“It was good. I like the showers here,” said Tony as he put his toiletries up and hopped into his bed.

“Uh huh. And you look different than when you left, but I can’t put my finger on it,” said Andrew as he shifted his body towards Tony and pulled his head set off of his head.

“Well… after a long day of travel, a shower always makes me feel nice and refreshed. It’s probably just that you’ve never seen me clean.” Tony said as he absent-mindedly rubbed his exposed hairy belly.

“Hmm, okay. I will say you might want to invest in some new pajamas. It looks like that pair doesn’t fit you anymore. And with you saying that you’re wanting to grow even bigger, I bet those won’t last long.” Andrew put his head set back on and resumed his game as Tony’s cock jumped a little bit from the excitement of Andrew’s words. Grabbing a pillow to cover himself, Tony blushed a bit and made sure his now larger dick wasn’t seen.

“Haha, you got that right. I think I’ll be doing plenty of growing this semester. And I won’t stop until I’m the biggest there ever was.” Tony laid his head back on his pillow and took a deep breath to clear his head. He smiled to himself as his mind began to wander into the fantasies of how big he would grow.

“Sure, whatever you say, big guy. Are you gonna go to sleep now?” asked Andrew, leaving one ear off his headset.

“Yeah. I have my first day of classes tomorrow and wanted to get a good night’s sleep before it,” said Tony as he shifted his weight on his bed. Now amazed at just how far his feet went down the bed.

“All right, I’ll finish up this game and turn everything off so you can get some good sleep. Besides, I have a class at 8am tomorrow, I should probably head to bed too,” said Andrew. Tony looked down and actually saw his pecs obstructing his view of his body and still couldn’t stop smiling. He did feel his cock jump again, but had to resist reaching down and feeling his new endowment. Even though he was under the covers, he could see a bulge wanting to break free and grow. This thought only made the bulge under the sheets jump with even more excitement. Tony tried to focus on other things, but his horny thoughts were getting to him.

“No need to rush.” Tony mused as he turned his body to face away from Andrew only to hear a rip shoot through his pants. Tony’s eyes shot open and he turned to look over at Andrew. But with his head set on, Andrew didn’t hear anything. Turning back to his body, Tony saw a little wet spot on the blanket that must’ve been a small bit of pre that leaked out when he tore his pants.

“Just finished on a good one. Perfect way to end a good day,” said Andrew as he turned off his console and tv. He laid down on his bed and reached for his light to turn it off. “Tomorrow will be a good day. First day of classes. First full day with a new roomie, we have a lot of things to be excited for.” Andrew hit the switch and the light in the room went off.

“Definitely. It’s gonna be a great day. And a great semester. Goodnight Andrew.” Tony rolled back over onto his back. Now with his boner hidden by the darkness.

“Night Tony.” Tony sat there quietly waiting for Andrew to fall asleep. Once he heard a light snore coming from Andrew’s bed. Tony wiggled his big body out of his pants and underwear so he could feel his big enhanced member. He felt another shot of pre leak onto his hand as he put two hands on the mighty rod. Tony looked over at Andrew and heard him sleeping before, but decided to risk it all by starting to jerk off.

Tony felt how big his cock felt in his hands now. He couldn’t believe that he needed two hands just to jerk himself off now. And his hands felt like they barely closed around the monster, it was so thick. One of his hands left his cock to feel the rest of his improved body. After feeling the heft of his pecs, Tony knew it wouldn’t be long before he was shooting cum everywhere. Between having an obscured view of his dick and the fact he could feel how juicy they felt with each lift, he had to stifle a moan as his big body turned him on so much.

Sensing what was about to happen and feeling how much bigger his balls were, Tony reached back behind him and grabbed a few tissues off of his desk. Only after feeling how round and expansive his belly was did Tony start firing shot after shot of cum. It was the biggest load he had ever produced as volley after volley of cum hit his hairy belly. Tony panted as the orgasm subsided and looked over to Andrew who still seemed to be fast asleep. Grabbing the tissue, he started wiping off the excess cum on his belly and was surprised about just how much he had to clean.

After grabbing another tissue, Tony finally cleaned up the mess he made and pulled his blanket back up to cover his torso. He thought about pulling up his pants, but they were already ripped so why bother. He turned to his side and closed his eyes to go to sleep, wondering if every day of college was going to be this eventful. And if it was, it was going to be an incredible year.

Tony rolled around in his bed and grunted as he heard shuffling around in his bedroom. He groaned as he turned to face Andrew’s bed and the rest of the room as his eyes peeled open.

“Good morning! Sorry if I woke you,” said Andrew as he pulled a blue t-shirt over his head. Andrew was dressed already as Tony grunted and shifted in his tiny twin bed.

“It’s okay. I had to get up soon anyway.” Tony yawned and leaned forward. Still not used to the new weight his body had. Looking at the analogue clock Andrew had on his desk, it was 7:30 am. He still had an hour and a half before his first class.

“Well, I’ll get out of your hair. I’ve got microbiology in thirty minutes and I want to get there early to talk to my professor about my winter break experiments,” said Andrew as he gathered up his journals, plants, and test tubes. “I have so much to show him. I just hope he has time to see me today.” Andrew stuffed everything he could into his backpack until it was practically bursting.

“I’m sure he has time for one of his top students,” said Tony, a smile shining through his groggy expression. Andrew blushed and heaved his backpack onto his back with much labor.

“Uh huh, whatever you say. I’ll see you later Tony. Have a fun first day of class.” And with that, Andrew walked out of their dorm room leaving Tony alone.

Tony laid back down and kept his eyes open for a moment. He could hear plenty of other doors slamming closed with various other boys on the floor getting up to go to class as well. He stretched his body in his bed, but was quickly reminded how painfully tight his pajamas were. His dick felt like it was being twisted and strangled inside his underwear. Tony looked up at the door and pondered for a second. Andrew wouldn’t be back before he had to go to class.

After a quick mental deliberation, Tony shucked the covers off and looked at his bigger body. His belly stuck out from him like a dome and his pecs blocked some of his view of it. Tony had never been a super hairy guy, but he did have little black curls sprouting from his body. They seemed to look even more pronounced against his pale white skin now that their canvas had grown bigger.

“I wonder if you’ll get any thicker?” mused Tony as he t one of his curls up in his fingers and tugged at it. Bringing his other hand to his face, Tony felt his uneven beard on his chin. He had always wanted to grow facial hair, but never had any real success with it. For one thing, there was always a big patch of hair that could never grow in on his chin and his beard always looked incomplete. Even his mustache was faint compared to most men’s. It looked like he had a caterpillar on his lips when he grew it out.

Tony sighed and looked back down at his stomach only to see a tent rising higher behind it. Tony smirked and used his big hand to grip his cock in its cloth prison. “Fuck I don’t know what gave you this boost, but I love it.” Tony stroked himself up and down as his cock grew in his pajamas. Tony didn’t waste any time shimmying out of his clothes to reveal his fat cock throbbing in anticipation.

Last night when Tony had had his little jerk-off session under the cover of darkness, he couldn’t get a good look at just how big his equipment had grown. He had only been a meager 3 inches in the cock department before last night, but now he looked to be almost 7 inches long and as thick as a golf ball. His bulbous head waved at him as it sputted pre onto his large belly.

“Fuck, did my balls get that much bigger?” Tony asked himself as he reached down and felt his balls. Looking down, they were the size of chicken eggs in his scrotum. Tony jostled them around for a bit and felt their weight. He was surprised at how much cum he had stored inside considering how much he blew last night.

“Do I have time?” Tony turned to the clock again and saw it was only 7:45. He still had plenty of time. Tony wrapped his hands around his cock and started jerking himself off. He fished for his phone on the bedside table and pulled up some of his favorite videos of hunks growing larger. He settled on one of a muscular football player outgrowing his uniform in the locker room.

Sitting in his bed, he watched the video of the jock growing bigger, outgrowing his clothes and padding. Tony stroked his cock slowly as he shivered. A spurt of pre escaping his slit as he moaned. He watched the jock begin to tower over everything in the locker room and Tony could tell his balls were about to reach their full capacity. The video ended as the creator advertised their Patreon and Tony closed his phone.

Closing his eyes, he jerked off his cock and tried to hold back his load. While focusing hard on not cumming, he could feel the strain his clothes were putting on him. His pecs were about to explode out of the neck hole and with one wrong flex, his biceps could demolish the sleeve. Even his underwear and shorts that were hanging around his ankles and calves felt like if he extended his legs, he’d rip them in half.

In an exhibition of his strength, Tony flexed his pecs and shoved them forward. A tear formed down the middle of the shirt making it a v-neck. He flexed his biceps and his arms burst out of the fabric now making the v-neck shirt a sleeveless one. Finally, Tony spread his legs open and he split his pajama bottoms into two separate pant legs without even trying. All of this show of strength was more than enough to put Tony over the edge. He started shooting cum like a fountain. Cum hit his clothes, his belly, his sheets, everything. He painted most of his side of the room with it.

After what felt like a gallon of cum had been shot out of his dick, Tony basked in the afterglow of his orgasm. He saw his clothes in tatters and chuckled a bit. He grabbed the sides of his shirt and finished the job his pecs had started by ripping his shirt apart straight down the middle. With his clothes just rags of cloth now, Tony grabbed at them and started to clean up his cum splatters he’d made all over himself and the bed.

“Good thing Andrew’s plants provide enough of a smell to mask all this cum.” Tony was surprised at just how many spots he hit with his cum. He’d expected his orgasm to be big, but this was on another level. Once he felt like he had adequately cleaned off all the cum, Tony stood up and threw all of the remains of his clothes into the trash can beside his bed. He grabbed his sheets and started to strip the bed. “I’ll throw you in the laundry later.”

Tony rose up from the small bed and stretched his big body. Reaching up towards the ceiling, he could see the tops of the plants in the window sill. He must’ve been 5’9 compared to how much his old clothes rode up on him and given his elevated view. Stretching his body down, Tony could finally look over his belly at his feet. He’d gone up at least two shoe sizes. “I’m gonna have to get some new clothes.” He wiggled his toes and even they looked longer than usual.

Straightening back up, Tony walked over to his closet. He pulled out a once oversized t-shirt and held it up to his chest. “Maybe this will fit.” Tony threw the shirt over his head and started to squeeze his head through the top hole. He could already tell from his neck alone that the shirt was gonna be a tight fit. Pushing his arms through the holes, his biceps got stuck on the sleeve. He hadn’t even moved his arm and the sleeve felt ready to burst off him. Pulling the shirt down, his pecs bulged forward leaving little material to cover up his gravid belly. Not even his belly button was covered under the t-shirt that once fit him like a dress.

Reaching for his chest of drawers, Tony pulled out a pair of underwear and looked down at his dick. He reached down and put each of his legs in the holes. Pulling them up, they started to tighten up on him as they glided across his thunder thighs. Getting up to his nether region, Tony had to reach down and stuff his dick and balls into the underwear. Tony adjusted himself as best he could in the limited space he had until he was satisfied. Letting the underwear go with a loud snap, Tony felt his bulge being strangled. “I just can’t get hard or else I think you might snap all the way off.”

Refocusing himself, Tony grabbed a baggy pair of sweatpants and put them on. They fit him pretty well until they got to his fat ass. Tony pulled on his pants and started jumping up into the air. “Damn, Beyoncé wasn’t kidding when she said ‘If you don’t jump to put jeans on, baby you don’t feel my pain.’” griped Tony. Finally, he managed to get the pants over his hump.

Tony turned to face the wall mirror all dorm rooms had and his jaw dropped open. He looked obscene. His shirt looked like it belonged to a child the way it fit him. His hairy belly was on full display for everyone to see and if he even slightly moved his arms, it threatened the sleeves bursting off him. His bottom half didn’t look much better. His thick legs looked stuffed into the sweatpants like meaty sausages. His entire ankle and some of his shin were fully exposed from how long his legs had gotten. Every curve and bulge could be clearly seen from the front, back, and side—including his biggest bulge, which stuck a few inches out from the rest of his body.

“I can’t go out like this. Not on the first day at least.” Tony rifled through his closet again for anything bigger that he could fit into, but to no avail. None of his old clothes would fit his new and improved body. “Nothing. Maybe I can get something at the campus store? But I still would need something to leave the dorm in.” Tony pondered for a second as his eyes wandered to the other side of the room.

Andrew wasn’t nearly as stocky as Tony was now, but he was tall. He had to have at least one thing that could fit him, at least in the shirt and pants department. After giving the door a quick glance, Tony walked over to Andrew’s side of the room and looked through his closet for the most basic thing he could find that Andrew wouldn’t notice was gone before Tony could return it. “I’ll throw whatever I use into the washer with the sheets.”

Tony’s eyes locked onto a plain black t-shirt hanging in the back of the closet and fished it out. In an attempt to take off the t-shirt he currently had on, Tony tried to lift the shirt up and off him, but only managed to tear the poor shirt in half. “I’ll definitely need to get a new wardrobe this semester if I keep this trajectory.” Tony threw the pieces of fabric into the trash with his ruined pajamas and started to put on Andrew’s shirt. Pulling it over his body, it was a much better fit than anything Tony had in his closet. He still felt his belly and pecs fighting the tightness of the fabric, but it would have to do.

Looking at his selection of pants, Tony grabbed a pair of sweatpants as he wiggled his way out of his. Kicking them up onto the bed, Tony started to put on the new pair. This time with much less difficulty getting them up past his dump truck ass. They were actually a little loose on him and hung down past his ankles. Even his bulge looked normal in them. “I’ll have to ask Andrew what size he wears.”

Tony gave himself a quick once over in the mirror and he looked as good as he was gonna get on short notice. Tony started gathering up his school supplies and heard a sudden crash of thunder. Tony peered out of his dorm room window to see a cloudy sky coming towards him. Little drops of rain started to hit the window as he gathered his things. Looking over at the clock, Tony’s eyes widened when he saw it read 8:45 “Shit, I may have gotten a little carried away.”

Grabbing for some socks, those still fit him well, but he had another dilemma, his shoes. His feet were going to be a problem. They had gotten longer and wider with his growth spurt. Looking around Andrew’s stuff, Tony saw a pair of sneakers. Grabbing at them and looking at the tag, Tony’s eyes went wide. “Andrew has smaller feet than I do. Even before they got bigger.” Tony bit his lips as he racked his brain.

Deciding to bite the bullet, Tony grabbed a pair of old, worn-out tennis shoes he had. Sticking his feet in them, they were definitely tight, but given they were old, they had enough give to at least fit Tony’s feet inside. “This will have to do.”

Tony grabbed his backpack and was out the door. Hurrying his way down the stairs, Tony could feel his walk was now more of a waddle thanks to his thick legs. When he reached the bottom of the stairs, his stomach let out a loud grumble. “This body needs fuel. I should have time for a quick breakfast.”

Walking through the dorm, Tony made his way to the cafeteria and saw a big buffet of food out. The delicious scents of bacon and pancakes filled his nose and his stomach growled again, louder this time. “I’ll make time for you stomach. Hold on.”

Tony rushed to the buffet line and loaded up a big plate of food. He licked his lips as he piled massive stacks of food onto his plate. Tony swiped his campus ID at the cash register, sat down at the nearest table, and immediately dug into his feast. He shoveled food into his mouth like a trash compactor and didn’t stop to take a breath until his plate was empty. “Wow, I was hungrier than I realized.” Tony got up and put his plate near the dishwasher and hastily left the building.

“Shit…rain.” Tony exited his dorm to the thunderstorm outside. He held his hands over his head to cover himself as best he could, but there was a torrential downpour of rain. Tony walked through puddles on the street and tried to look at the map on his phone to find the kinesiology building. While looking at his phone, Tony noticed the time, 8:55.

“Dammit, hopefully other people got lost in this rain too so I’m not the only one that’s late,” said Tony as he started running through the water. His new and improved body jiggling up and down as he did. “This extra heft isn’t helpful in a rushed situation.” Tony grabbed at his stomach and attempted to keep it from bouncing so heavily up and down as he ran, but with the rain getting everything wet, his body just felt heavier and heavier by the second.

Finally getting to the building, Tony hustled inside and saw other students filing into the classroom. Shaking his head like a dog, water flew off of Tony’s body. Getting a look at himself, Tony’s eyes widened. The rain had made his outfit into a wet t-shirt contest. Every passing observer could see every bulge, every curve, every inch of Tony’s bigger body. Some students kept their eyes on Tony for a little too long. Eyeing his engorged nipples in his shirt.

Shrugging off the looks, Tony walked into the large auditorium hall and saw most of the seats had been taken already. His eyes scanned across the room for any open seat, but there were only a few seats left. Trying to be as inconspicuous as possible, Tony stood in the doorway for a moment finding the best seat for his big body to squeeze into.

“Excuse me, young man?” came a voice from the front. Tony turned his head and saw a man that appeared to be in his late 50’s or early 60’s talking to him. “There are plenty of seats here in the front row for you.” Tony froze like a deer in headlights as more heads turned to face him.

“Um, sure. I guess I can sit up front today,” said Tony unenthused.

“Good, good. Now come, we have to get this class started.” Tony followed the professor down the steps to the front row and sat down in one of the chairs in the front. Luckily for Tony, there were very few people in the front row so he was able to find a seat that he could stretch out his big body.

“Good morning everyone! I hope the rain wasn’t too much of a hindrance for all of you this morning. My name is Professor Bigby and welcome to introduction to anatomy and physiology,” said the professor. Tony leaned back in his seat as the professor continued to talk about the class.

“Today will be an easy day for you all. I’m not gonna be mean like some professors and assign a ton of homework on the first day. We will just go over the syllabus, some expectations for the class, and I have this worksheet for you all to do before you leave just so I can get a good basis for how much knowledge you all have for the course already.” Tony listened to the professor talk, but he felt a weird sensation building in his stomach.

“I’d also like to introduce to you all my TA for the semester, Mr. Washington.” Professor Bigby extended his arm towards a young man standing up against the wall on the other side of the room. “If you have questions about your grade or need some help with your assignments, he will be your first point of contact before contacting me. We both will have office hours, but I’ll get to that in the syllabus.”

“Hi everyone. My name is Trent Washington, but you can just call me Trent. I promise I’m not the harshest grader in the world despite what your grades might reflect,” said the young man. “I have your syllabi right here, but it will also be on our website if you lose this one.” Tony admired the handsome TA as he walked around the aisles passing out the syllabus. He was definitely cute. Couldn’t be older than 25 with a sharp jawline.

“As Trent passes the rest of those out, I’ll start going over some things with you. My expectations of this class for you all is that you will be here on time and ready to learn. A majority of my teaching style relies on your participation in class and that is what one of your grades will be. Now getting into the units. The first unit we will cover will be the musculature of the body and how it interacts with the rest of the body. Then we will cover the skeletal structure attached to the muscles and get into each specific bone. The next unit we cover will delve into the organs of the body and their processes…” Professor Bigby’s voice drowned out in Tony’s head as he ogled the TA.

I’d love to get to know his anatomy, thought Tony as he gazed at Trent’s chest. In the button up shirt he was wearing, Trent’s pecs stretched the buttons of it to a shocking degree. If he breathed in too heavily, the poor button might pop off. Tony felt that same warm feeling in his stomach bubbling up as Trent handed him a syllabus. Up close, he looked even more dreamy.

“Here is the syllabus and here’s the worksheet you’ll turn in at the end of class, big guy,” said Trent as he locked eyes with Tony. His big brown eyes dazzled Tony as a lightning strike lit up the room.

“Thanks,” said Tony in a fluster. He felt his stomach bubble again and he groaned a bit as Trent walked away. “Maybe I shouldn’t have eaten breakfast so quickly.” Tony grunted and rubbed his belly. Something was happening in his body again.

Tony failed to notice that he was no longer dripping wet with water. His body was slowly absorbing the water on his body and getting it ready for another growth spurt. It started first with Tony’s belly. It seemed to bulge out in front of him little by little until it peaked out from below Andrew’s shirt.

“Again? Really? Here?!?” whispered Tony to himself as he looked down to see his body expanding again. He saw his belly was bulging out in front of him. He was really regretting sitting in the front row now. The next part to transform was his pecs. The poor t-shirt stretched out as his pecs swelled bigger. His nipples became even more pronounced in the shirt than they already were. As much as Tony was loving the size he was gaining, he wished he could shrink away and not have it happen in front of an entire class of students, his professor, and the hunky TA.

The next things to grow were Tony’s legs. Tony had been happy that Andrew’s pants were long enough for him, but that was quickly becoming untrue. His legs extended further down into the ground and the pants rode up to his ankles quickly. Within the pants, Tony’s thighs were thickening to look like the sweats were painted on him. Tony then felt a pull at his side as his ass began to grow. His hips widened and his ass plumped up bigger in the seat. On each side of Tony, he could feel his ass wedging itself into the small auditorium seat meant for a much skinnier student. Tony worried that if he stood up, he might take the seat with him.

Feeling his pants tighten again, Tony reflexively put his backpack in his lap suddenly. His cock was throbbing out of his too-tight underwear. The one thing he hadn’t replaced. His balls once again filled out the front pouch to the point the underwear was bending forward to keep up with their size. Tony shuddered when a snap rang through the room. The waistband of his underwear had given out and his cock and balls were free to grow. “So much for not getting hard in these.”

“Psst, hey buddy,” came a voice from behind Tony, “can you maybe lean over? Or sit in the back next time? We all can’t see behind you.” Tony turned around and saw his head was higher than other students’ in the row above him. He’d been growing taller this whole time too.

“Uh yeah. Sure man. I just was late so this won’t be a proooblem again.” Tony bit his tongue when he felt his feet in his shoes extend. Tony winced as his old pair of shoes ripped a bit and he was given some relief. But it wasn’t enough as his feet grew bigger and looked stuffed in the shoes like a Thanksgiving turkey.

“Now it’s time for the worksheet class. Once you finish the worksheet and turn it in to Trent, you are free to go,” said Professor Bigby. Tony tried to focus back in on the class, but he was still growing. Looking at the worksheet, all Tony had to do was identify muscle groups in the body.

Okay, I can do this. Finish this and then I can find out what’s going on, thought Tony. Okay, number one. Those are the pectorals. As Tony wrote the answer, he could feel them swelling again. Next, biceps. Tony’s sleeves tightened around them. Abdominals, Tony’s stomach blocked up and inflated bigger again. Abs are overrated anyways. Next, trapezius. Tony’s head got smashed between his growing traps. Deltoids, Tony’s shoulder’s hardened and his form widened to form tears in his shirt. Latissimus Dorsi, Tony felt his wings grow into the armrests next to him and spill over into the seats beside him. Good thing no one else sat in the front row. Next, Quadriceps and Gluteus Maximus, tiny rips began forming in Tony’s pants as his legs swelled like balloons.

Other students started walking their worksheets up to the front and put them on the professor’s podium. As they turned to leave the class, all of them gazed at Tony’s now hulking form. He looked like he was sitting in a small chair meant for a kindergartener. Gotta finish and quick. Last ones. It’s the calf muscle, but I don’t know what it’s really called. Tony racked his brain as his shins and calves poked out from the bottom of his pants. Fuck it, I’ve gotta get out of here.

Tony tried to get up, but his fat ass made it difficult. With a bit of work, Tony managed to pop his big body out of the seat and hastily threw down his assignment on the podium and ran out of the room. He could feel the new weight on his body again as he lumbered up the stairs to the door. He put his hands in front of his cock and balls as they bounced freely.

Bursting out of the door, Tony ran straight to the bathroom. Looking in the mirror, he saw his face for the first time since this morning. He’d almost grown a full beard and mustache since he’d jerked off. Looking down at the rest of his body, he noticed the hair on his body had grown longer again. And was looking much thicker than before. Reaching up and cradling his head, Tony grabbed at his hair, but didn’t feel any resistance. He brought his hands back down and smoke of his black hair fell away into the sink.

“What the fuck is happening to me!?!”
