Story by Arubazu, enjoy!
As a door opens into a household, two teens enter a home, shuffling through the front door and closing it afterward. “Welcome to Casa del Martin” one of the teens announced clad in a hat, hoodie and some jeans he flashed the other teen a playful smile. “O-oh yeah…hehe” the other teen chuckled, his name was Andreas clad in a t-shirt and jeans as well his shy nature was getting the best of him. “Awww come on don’t be so shy…with a body like that you don’t have any reason to,” Martin spoke and to be fair he was right. Andreas was built like a big teenager athlete thoroughly muscled for his age, with bulging pecs, and a nice pair of biceps and an impressive 6 pack of abs martin peaked at him having in the gym. He was super sexy but surprisingly very shy too, “O-oh y-yeah..” Andreas follows with a bit of a stutter. “Don’t worry I’m guessing this is new to you. I will be easy as we explore all of this together okay?” Martin says giving Andreas a reassuring pat on the back. Andreas paused before blushing and nodding being that this was his first time doing something so, well naughty, he followed Martin into the living room.

Andreas paused before blushing and nodding being that this was his first time doing something so, well naughty, he followed Martin into the living room.
Martin gestured for Andreas to lay down on the couch and whispered into his ear. “So.. I won’t lie to you I have a thing for guys with big muscles so imma have fun feeling you up and down.” That hushed whisper was a bit arousing to Andreas as he lays back feeling his muscles getting gently touched by Martins’s warm hands starting with his biceps big as oranges for his age. Martin seemed so enraptured by touching them and feeling how strong and hard they were. “Hoho… so nice…look at your sexy body..” Martin says to Andreas. The compliment making him blush shyly and shuffle a bit awkwardly. “Oh…uh…thx” he manages to get out between stutters as he feels the touches continue. “Alright..onto the next part,” Martin says as he slides his fingers under Andreas’s shirt slowly lifting it up over his head and tossing it across the way to the floor. His athletically fit body now bare all for Martin to see and he follows suit taking off his hoodie and tossing it to the side. His more thinner normal body exposed. “There, just so your not alone buddy.” Martin gives Andreas’s cheeks a gentle rub and it eases his nerves. “Thanks… it does help” Andreas says with a slight blush still apparent on his face.
Martin has a smirk on his face as he feels down upon Andreas’s muscular chest, feeling his firm pec’s grazing his hand across the muscle before his hand grazes one of his nipples making Andreas gasp real quick from a tingle of delight. A smirk appears on Martins’s face as he plays around with Andreas’s nipples some more causing jerks of pleasure from him before he promptly moves on feeling up Andreas’s impressive 6 pack of abs. He smirks a finger sliding between every crevice getting his face close upon the display of muscle to give it a gentle lick making Andreas shudder from such an unexpected action. Another gasp breaks from his lips before he and Martin lock eyes. “Too much?” martin asks with a smirk, Andreas shakes his head “no keep going…t-this feels nice..” he replies back to the other teen. Martin goes lower and begins to unbutton Andreas’s jeans taking them off to reveal his baggy boxers. He tosses Andreas’s jeans to the side quickly before following suit with his own jeans. He playfully spreads Andreas’s legs and rubs them getting a reaction out of the teen’s well-sized cock making a noticeable bulge in the undergarment. Now clad in just undergarment the two stared at each other in slight awe. “Hehe..now for the real fun!!” Martin says as he gets up off of Andreas he moves to his backpack he tossed to the side of the room to pull out a sorta lotion substance. “Now this will make those muscles really shine!!” Martin announces with glee before moving back to Andreas. “What is that?” Andreas asks curiously enough, Martin takes a moment to pause, “uuh its that…uuhh oil that makes muscles shine…yeah that.” he answers in a most peculiar way. Andreas looks at him for a moment, unsure as to why Martin would have such a thing being that he doesn’t look all that fit but maybe it fits into his needs sexually. Martin dips a hand into the oil and he turns to Andreas with a smile, “Alright imma cover you up thoroughly” He says as he begins to apply it to Andreas’s body. Starting from his biceps once more feeling all around them, those bulging muscles as his fingers slide around that lifting ball of muscle up the forearm and back on both sides, he moves down to give his pec’s some of the application to feeling those slabs of muscle move as Andreas breaths. Martin dips his hand into the stuff again and continues his venture. Down into the rows upon rows of abs, Andreas held, getting every crevice before spreading it out through the rest of his chest. Andreas felt weird but in a good way so far through all of this, he jumped when he felt Martins’s next action as his hand slid between one of the leg holes of his underwear groping his cock. “W-Woah” Andreas jumped but Martin smirks with a wink, “Gotta get everywhere you know. You got a good size on you too” he compliments Andreas who blushes rubbing the back of his head. Andreas watches as Martin continues going down his legs applying the oil to his body his skin having a lustrous shine before going away near immediately as martin finishes up he notices his container is empty. “Oh darn… I knew this wouldn’t be enough.” he says almost disappointed, “I will get some more be right back” Martin informs the other teen, Andreas gives him a slight nod watching Martin leave the room rushing up the stairs.
Silence fills the room as he is left to his own devices his skill feels smooth after all that stuff application and almost tingly too. But to his surprise, the feeling doesn’t subside after a moment but changes to something he couldn’t put his finger on it but it felt so good. He let out a slight moan before looking down at his body, eyes widening seeing what was happening, his body his very muscles were beginning to grow. He turns to look at his biceps as they begin to swell and pulse bigger and bigger becoming softballs of round muscle on his arms. His shoulders broaden to hold onto his strong powerful new arms, the sensation of his growing body sending waves of pleasure throughout him making moan loudly. His pecs follow soon afterward ballooning up and becoming powerful shelves of muscle blocking his view of his growing and tightening abs. Soon another row makes its appearance giving him a powerful 8 pack then another to a whopping 10. He feels his underwear tighten around his legs and waist and is able to peak over his powerful pecs to see his waist and legs growing too. Even his cock and balls began to expand with his body sneaking out of a leg hole as it reached .4 meters soft and his balls become the size of small tennis balls struggling to be contained in his tightening underwear. He moans as his powerful legs grow thicker and fuller with muscle and his body is taking up more of the couch. He was growing not only bigger in muscle but in height to realizing his legs reached over the other end of the couch as he pulls his legs back to keep himself on it. He pants and moans as the growth pauses to a halt, a pleasurable sensation wrapping around him “w-what happened!! That felt amazing!!” he says before he hears a gasp on the other side of the room. Martin returning with another jar of that oil stuff. “Well, then it looks like you grew without me. It’s amazing how well this stuff works” he says with a mischievous smirk.
Andreas looks at Martin with extreme need and lust in his eyes now lost in the haze of his newfound growth and the pleasure wrapping around his body. Martin smirks “oh need some attention?” he teases playfully as he walks closer to Andreas. He sits on his chest interested to find the other teen grew a good bit taller than him. “Don’t worry there’s more in store for you,” Martin says with a mischievous smirk. Andreas simply nods wanting nothing more than to be pleasured right now, Martin began once more applying more of the oil to Andreas’s body feeling him up all over but this time it was more potent and reactive. Andreas can feel the sensation return as his body grows bigger again, muscles throbbing as they grow bigger. Martin can feel and see the growth as he lathers the other in the oil, the muscles bulging under his touch, moving from the biceps that grew bigger than the softballs they were and felt so thick and hard he could barely put a dent in them. Those shelves of pec’s Andreas had grown two stone slabs of pure powerful muscle that martin played around with giving them a few squeezes even giving his nipples a few play full flicks making Andreas’s body twitch in delight a loud moan escaping from his lips. Martin fondles Andreas’s pecs, even more, squeezing the hard muscles as they grow to push back against his every touch. Martin sat upon a sea of abs as Andreas’s 10 pack grew to the ever legendary 12 a finger sliding down the crevice between each to satiate his hunger for more. All of this growth caused Andreas’s massive pleasure as his growing body grew past the 2.5-meter mark taking up most of the couch, there was a loud shrip sound that filled the room between the two’s moans. Andreas’s cock had broken from its confines of his tight underwear slapping against Martins back making him shudder in delight to feel that hot thick cock against his back. He reached around to grope it feeling the head slide back and forth against his lower back. Martin turned to witness the rest cock so big it laid on his stomach and smiled kissing the cock head dripping with pre-cum. Andreas lets out a loud moan his hips bucking in pleasure. “FUUUCK YES!!” he shouts as he grips to couch he was growing bigger than tightly. His body still expanding bigger and bigger as it inches just beyond the confines of the couch to the point it begins to creak under his weight. Martin continues his advances pleasuring the growing teen stroking that massive cock with one hand and licking and sucking the head as well. Firm in his advance as Andreas gets lost in the pleasure moaning loudly to the point of egging on Martin with his grunts. His hips bucking till they hear a loud snap as the couch breaks from Andreas’s growth. Now at 3.5 meters in height his head bumped against the wall while his feet sprawled out on the other side of the room. His powerful cock still twitching eagerly as Martin gave it his all blowing it. With a powerful 1 meter in length, the cock took a lot but it was so arousing that Martin couldn’t help but stroke himself.
Martin resting atop of the muscle giant sucks and licks at that cock as the giant continues to flex his powerful muscles moaning loudly. Andreas’s cock began to leak pre-cum and Martin can taste the contents filling his mouth but he eagerly takes in gulp after gulp of the contents. “OOoooh I feel so Close!!” he moans out loudly. His hands against the walls for balance as Martin continues his advances. Moaning himself in hot arousal from getting this muscle giant off, stroking his own cock listening to the loud powerful moans he was releasing through the room. His foot against those canteloupe sized balls for balance as he continues to go at it, tongue deep in his cock slit to drive more arousal from the other teen till finally with one last buck of his hip and a loud powerful moan. Cum shoots out of his cock Martin the first to get a face full of the hot seed before it shoots onto Andreas’s chest and gets all over the walls too. The sight of that powerful dick shooting wave after wave of his seed sent Martin over the edge as he cums too. The two finally lay back panting in their little afterglow, both sitting in the combination of each other’s seed looking up at the ceiling of the room. Martin rolls over on Andreas’s chest climbing up to look him in the eye, “Hehe who knew that stuff would be so effective, I hope your ready for another round and with some of my friends too.” Martin says playfully as he fondles Andreas’s pecs once more making the other teen let out a slight gasp before his brain finally took in what he just said. “W-wait friends..?” Andreas asks in confusion, “hehe yeah don’t worry, your not gonna be the only big guy today, I got so much more of that stuff.” Martin says with a mischievous smile shaking an empty can of the stuff in front of his eyes followed by a knock on the door.
