A growing study

Storys written by my friend Arubazu, enjoy!

It was all going as planned, on the last day of school before the weekend Martin invited his friend,Nathan, over to study since classes have been so hard on the both of them. But that wasn’t really the reason he invited him over, he had gotten some stuff from a friend that he said would feed into his fantasies. Martin hesitantly took it but nonetheless wanted to try it and what better subject than his friend he had a crush on. If this stuff really works then he would get to see nathan huge and muscular. Always had a thing for bigger guys and wanted it to happen so bad to his friend. As he began to fantasize on the thought the doorbell rang to his home. He quickly grabbed his hat covering his tuft of brown hair and rushed to the door. Opening the door he is met with his friend Nathan standing at the doorway with backpack in tow. Wearing a black short sleeve shirt and classic jeans to match. His blonde hair frayed in the front and green eyes. He stares back into Martins green eyes before speaking “ So you gonna invite me in?” he says jokingly to which Martin jokes back “ I was seeing if you had a housewarming present for me.” To which Nathan playfully punches him in the shoulder causing the two to chuckle before walking into the house. Passing by the kitchen towards Martins bedroom. Nathan rushed in sitting on his friends bed tossing the backpack full of stuff aside. “Alright so how are we going to start our study session?” Nathan asks. “ Well i was thinking we start with homework, then get to doing something fun.” Martin answers playfully. Nathan chuckles “ Dude thats not how studying works but I won’t complain”. “ How about drinks to start us off and you can set up where you wanna do homework sounds cool?” Martin asks. “Sure sounds good I’ll take anything you have to drink tho, you guys usually have awesome stuff.” Nathan says back. Martin takes a moment to think he how he doesn’t even know and smiles. He leaves to the kitchen to grab the special stuff was liquid in nature so he just hid it in the back of the refrigerator. He opens the jar and takes a smell just in case it has a scent to it that gives it off. Surprisingly enough there was no smell so he decided to take a big jug and pours it in as well as pouring some juice into it as well, to his surprise it dissolved nicely not even leaving a trace of its original color. He decided to get himself a different color juice as to not mix himself up before returning with the two large glasses. Nathan had seemed to have taken out his homework and started working on it. His shoes tossed to the side as he lays on the floor, eyes darting upwards as he notices Martins return. 
Martin hands him his glass with the special stuff inside it and Nathan takes a moment to drink it down before entering a coughing fit. “Oh No, you Okay!!?” He screams panicked for a moment the stuff might have been poisonous. “No,,,,*Cough* …No… drunk to fast…went down the wrong hole for a moment” Nathan answers pounding his chest and coughing a bit more before continuing to drink. This sets Martins mind at ease knowing he didnt kill a great friend trying out something new. “This stuff is good tho” he says as he drinks it all down. Well it was easy to get the stuff into him so now i just gotta wait and see the effects happen Martin thought as the two begin to work on the homework at hand. Martin decided to lay next to Nathan to get a closer view of the supposed effect of this substance. Nothing happened first much to his disappointment, but then he noticed the changes as it began. Nathan’s arm was slowly thickening, filling out the sleeve of his shirt bit by bit his bicep becoming thick with muscle actually. His chest seemed to slowly jut out too, Martin could swear he sees it slowly push out. He can see those back muscles slowly widen too. He looks back and sees his legs seemed a bit thicker filling out the room in his jeans and his socks seem smaller on his feet. Even his ass seemed more shapely than usual and he also noticed that there seemed to be a slight growing height difference too, as were their bodies were the same height now it seemed there was a bit more of nathan to be there. Martin was internally screaming for joy realizing it was working very well. He continued to watch his friend fill out his clothes, slowly growing.. Nathan gets up to stretch revealing how much he has grown, His close now tight upon his athletically muscular his body had gotten. His clothes riding up high showing a bit of midriff and calves showing. “Now that we are done with the homework how about we get started on that fun you said we would have.” Nathan says with a smile. “Oh buddy we are already having it.” Martin says with a smile, he can see nathan’s thick bulge seeming as his cock grew a bit with the rest of the growth. Nathan was confused before Martin pointed to him. “You should check yourself out , you looking hot right now or better yet.” Martin stands up in front of Nathan having to look up being that he was now at the height of the bottom of his chin. Nathan is surprised, “W- did you get smaller” Nathan says blushing a bit. “ Nope you got bigger, I made you get bigger” Martin answers with a smile he touches his arm, and chest too.”In more ways than one as well.” showing off his muscles too. Nathan was amazed realizing he was growing very muscular. Soon after the sound of ripping filled the room as his biceps were breaking through his shirt sleeves as they continued to grow more and more massive. His chest jutting out further and further, pec’s becoming true shelves of muscles at this point, His legs growing thicker as a tear forms up the side of them from their growing girth. Martin smiles as he continues to feel up his muscles and his body. Soon now pec level in height to his growing friend his shirt soon tore off his muscular frame revealing the rows upon rows of abs that hid underneath. “Man this is amazing!!” Nathan says flexing his growing muscular body. Martin smiles “ Yeah!! Amazingly hot don’t you think” He says as he begins to grope his friends crotch with a wide smile. Nathan let out a loud moan as his cock begins to stir to life. The erect member growing hard as the sounds of ripping and tearing fill the room till finally his erect dick tore through its cloth prison. All the scraps of is prior clothing fallen to the ground now standing before his friend nude, tall and muscular. Able to reach the ceiling by barely raising up his  and he was surprisingly still growing. He moans as he feels his friend worship his body, licking his muscles and cock in kind. He drops to his knees by now Nathan’s cock is as big and wide as his whole body. But that doesn’t mean he couldn’t pleasure it, wrapping his arms around the thick member and using his strength to jerk it from head to tip even using his friends massive balls as leverage to stroke it and the one thing that made it hotter is feeling it growing bigger and bigger in his arms. Feeling the cock and lengthen overtop of him before losing his grip to wrap his arms around it. He still gives it as best of a hand job as he can till finally Nathan lets out a loud moan as he cums hard growing through the ceiling as he does lucky for Martin he was under the cock  when he came. Protected from any falling debris. He peeks out to see even on his knee’s Nathan is bigger than his house and Nathan smiles once he sees his friend is safe. Picking him up and putting him on his bicep. “Wow that was intense” Nathan says excitedly cum dripping out of his cock still onto the house and street. 

Martin shouts out “Dude your so freaking massive, do you think your still growing?” Nathan nods to answer “I can feel it, i’m still growing” He says to his friend. “How about we test how tall I am and maybe have some more fun there?” He asks Martin. Martin gives a thumbs up wanting to see his friend truly grow massive. Martin decides to move somewhere safer just under Nathans chin as his friend runs to the city. He can see his neighborhood drift away as his friend runs off to the city. Everything seemed so small being up here and it was fun watching his friend rush by everything leaving colossal marks where he stood.  He could also see some of the ones left behind seemed smaller than the new ones being made. Soon they made it to the city and the two laughed loudly. Nathan by now was taller than any of the skyscrapers there and smiled as he put his erect cock gently next to one hearing the sound of breaking glass and crashing metal and stone. It also felt pretty erotic and so he continued, fucking the building hard, moaning so loud nearby buildings glass windows shattered, he smiled as he felt himself getting close till he realized he was taller than all the buildings already, falling on his knee’s he pointed upwards and came sending showers of cum down unto the unsuspecting bystanders bellow. He smiles before turning to Martin who had cum as well although not as climactic as him it was still a nice thing to see your best friend find something you did hot. He picks up his friend putting him down on a nearby skyscraper still intact from all the hot action. 

His entire body covering the city hovering over the building the two smiled at each other. “So you gonna have to invite me to another study session if it’s going to be like this” He says with a playful chuckle “Yeah this was sooo hot!! I can’t wait for next time.” he replies back. “ And maybe next time you will join me being a giant huh” Nathan says poking his friend gently to knock him over. Martin had the windblown outta him but chuckles embarrassingly at that remark.”Hehee maybe”
