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, however that wasn’t the reason he invited Nathan over. Recently he got a gift from a friend that would assist him with his deepest desires and daunting fantasies and Martin eagerly took it much to his dismay. However those fantasies were of a specific friend he had a deep crush on and always played a part in those desires, Nathan, so what better test subject than him huh.
Martin hoped this little secret stuff would work, mostly because if it did he would get the opportunity to see his long-time crush as muscular and big as he wished. If not, he’d be disappointed and feel like he was ripped off hard and played a fool. As his mind bounced between the rage of being ripped off and the fantasy of imagining his friend being big and buff, his thoughts were interrupted by the doorbell ringing through his home.
He rushes to the door to come face to face with his friend Nathan standing at the doorway with his backpack in tow. Clad in a black short-sleeved shirt and a pair of grey jeans to match, he turns away from the doorbell showing how his blond hair covers just a bit of his green eyes. Martin forgets how smitten he is with his friend as he pauses a bit too long to stare at his friend and he stares back at Martins before speaking out to break the awkward silence to him: “So you gonna invite me in or we just gonna get lost in each others eyes…?”, he says jokingly. Martin flustered for nearly getting caught diffuses and jokes back: “I was wondering if you had a housewarming present for me.”, laughing and sneering at his friend only to be rewarded by a playful punch from Nathan to his shoulder causing the two to chuckle before walking into the house.
Going into Martins’s house, passing through the kitchen and the halls, they head towards Martins’s bedroom. Once passing the threshold Nathan rushes 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 boredly asks eyeing Martins gaming consoles. “ Well I was thinking we start with homework, then get to doing something fun.”, Martin answers truthfully or at least half so keeping his concoction of delight an obvious secret. Nathan chuckles: “Dude that’s not how studying works but I won’t complain.”, eager to get this whole studying out the way so they can game as they usually do. “How about drinks to start us off and you can set up where you wanna do homework sounds cool?”, Martin plans as he gets ready to set into motion. “Sure sounds good I’ll take anything you have to drink tho, you guys usually have awesome stuff.”, Nathan affirms back giving his bud a thumbs up as he shuffles into a spot in the room taking stuff out of the backpack he threw. As Martin leaves the room he can hear Nathan saying slight curses as he struggles through the messy confines of his backpack. Martin takes a moment to admire that about him as well as how he delights with how surprised his friend will be.
Martin begins to head out of the room and down the hall toward the kitchen, reaching into the back of the refridgerator to where he hid the special stuff. Giving it a couple of shakes to see if its still sloshing around and to his delight it was. A dash of eagerness, giddiness and worry flash through his mind as now was the time for it to all come together, this was the moment whether or not it would succeed or fail. He takes the special stuff and begins to grab two different color glasses and pours the stuff in the red one, Nathans’s favorite color. After that, he adds a bit of juice to both of them to hide the mysterious look it woulda had with the stuff being an odd milky white color. Then with a bit of stirring, he mixes the stuff into the drink cleanly with zero traces whatsoever. His smirk widens as he begins to head back with the drinks in tow, and can already see Nathan is working on the homework with a bit of a struggle. Nathan seemed to have taken the homework part of their study group a bit too seriously as he could see the other teens’ furrowed brows and pensive stare at the papers before him. His shoes tossed to the side as he lays on the floor to get more comfortable before the sound of Martin walking in made him quickly look up.
Martin hands him his glass with the special stuff inside it and Nathan takes a moment to drink it down pretty fast as per usual he likes to chug his drinks and as if on cue Nathan goes into a coughing fit. “Oh no! You okay…?”, Martin says snarkily as he pats his friend on the back to get it out, some concern there but being the usual helped mitigate that panic. “N-No… I‘m coughing you dick….”, Nathan answers pounding his chest and coughing a bit more before continuing the rest of his drink. “One day I’ll master that”, Nathan points to Martin who just rolls his eyes in response: “Yeah sure bud if you don‘t choke first… you know I could become a doctor with the amount of times I have to save your life”, Martin jokes receiving a light jab to the shoulder and a shut-up from Nathan as he can see he was a bit embarrassed. “This stuff is good tho.”, Nathan remarks as he shakes his glass at Martin who simply pays attention to how his friend drank it all down. ‘Well, it was easy to get the stuff into him so now he just had to see the effects’ Martin thought, before Martin managed to nod in response as the two went to the homework.
Martin decided to lay next to Nathan to get a closer view of the supposed effect of this substance, and much to his dismay nothing was happening. He was cursing internally but as he turned again he noticed the changes begin. Martin’s eyes grew wide as he watched Nathan’s arm slowly thicken, filling out the sleeve of his shirt bit by bit his bicep becoming plump with muscle like a round baseball. Soon his chest seemed to slowly jut out too more and more as the front of Nathans shirt was beginning to be pulled by the growing muscle underneath. He can see those back muscles slowly widen too with his shoulders becoming bigger and broader. 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 the shape of ass was plumping and rounding out as his gets filled with muscle and soon to Martin noticed a growing height discrepancy between the two teens. Their bodies were the same height and now it seemed there was a bit more of Nathan compared to Martin in his own room. Martin was internally screaming for joy realizing it was working very well. He continued to watch his friend fill out his clothes, slowly growing more and more as now he had quite the athletic build and was still getting bigger.
Nathan gets up to stretch revealing how much he has grown fully his clothes now tight upon his growing muscular body. His clothes even riding up high showing a bit of midriff and 6 pack of abs and legs showing thick calves. A moan even letting loose from his lips as he stretches and Martin can see his bulge throb bigger and bigger like a fist in the front of his pants. “Can we be done with this homework and get started on that fun you said we would have?”, Nathan turns to Martin bored of the homework and would rather do something different. “Oh buddy we are already having it!”, Martin says with a mischievous smile as he sees Nathan’s thick bulge seem to throb bigger and pop the top button of his jeans as his cock grew just a bit more along with the rest of his body. Nathan moaned a bit but was confused as to why he felt so good 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 just at Nathan’s massive pecs as they grew thicker and plumper right in front of Martin’s face. Nathan is surprised: “W-Wait- did you get smaller?!”, Nathan says blushing as he grew bigger just a bit more. “Nope… you’re getting bigger! Just like I always dreamed off…”, 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 Nathan’s muscles and the rest of his body. Martin now being ab-level in height compared to his growing friend Nathan, said friend’s shirt tore off his new muscular frame revealing the now magnificent 8 pack 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 lustfully remarks as he begins to grope his friends crotch with an eager smile and gives it a nice squeeze on that plump meat too. Nathan lets out a loud moan as his cock begins to stir to life, eager to please the sounds of ripping and tearing fill the room as his erect dick tore through its cloth prison with massive balls holding an immense amount of cum.
Nathan had ripped fully out of his clothes with his growing body now able to reach the ceiling by barely raising his arm and he was surprisingly still growing. He moans as he feels his friend worship his body, licking his muscles and cock in kind making it leak and ooze and immense amount of precum. Nathan drops to his knees by now to let Martin continue his play and worship all the while his body still continues to fill the room more and more. Nathan’s cock was hard to please, now growing as big as Martin was tall and wide, but that just made it more enticing as Martin put his whole body into rubbing it off. Even using his friends – now medicine ball-sized – 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 lengthen overtop of him before losing his grip to wrap his arms around it. Nathan moaned out a loud as he leaks pre cum filling up the room with his mini bits of spunk, his back growing against the ceiling as he constantly gets bigger and bigger. He groans and moans as Martins bit of worship was working miracles at getting him off till he lets out a roar and cums and spiking his growth as he finally grows through the ceiling back first covering Martin from the debris. Protected from any falling debris he gazes upward and see’s how much he is eclipsed by whole of his friends body firmly in its shadow and that just makes Martin more horny as he gazes upward. Smirking on this Nathan plucks up his mischievous and horny little friend and puts him on his bicep. “Wow that was intense!”, Nathan says excitedly, cum still dripping out of his cock onto the house and street. Now having grown to quite the gargantuan muscle behemoth size.
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…”, Nathan responds to his friend feeling the pleasure of the growth and seeing the street get further and further from view. “How about we test how tall I am and maybe have some more fun there?”, He teases. Martin, who shudders at the thought, proceeds to give his friend two thumbs up, wanting to see his friend truly grow massive. Martin decides to move somewhere safer and nestles himself just under Nathans chin as his friend stomps his way in direction city. He can see his neighborhood drift away as his friend gets closer and closer to the city. Everything seemed so small being up here, it was fun watching his friend rush by everything leaving colossal footprints in the concrete that just seemed to get bigger and bigger with every step he took. It didn’t even take that many strides to reach their destination, the big city near their homes, that looked more like a playpen than anything by now causing the duo to laugh 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. Debris falling on his knee’s as his final thrusts bring him to the verge of climax. Finally he’s pointing upwards as the load 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 but it was still a nice thing to see. Your best friend finds something you did hot. He picks up his friend putting him down on a nearby skyscraper, still unharmed from all the hot destruction.
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 always ending up like this”, Nathan eagerly says with a playful chuckle flicking his titanic cock up and down. “Yeah this was sooo hot!!! I can’t wait for next time!”. Martin eagerly remarks back eager for the time he gets to see Nathan become a giant again. „And maybe next time you will join me being a giant, right?”, Nathan teases, wanting to have some fun with his friend too. Maybe even a crush reciprocated who knows…
