As Chris laid in bed his body was throbbing in pleasure, the young 13 year old moaning with half-lidded eyes as his body continues making his wish into a reality. His muscles being the first thing to grow as his pecs push his shirt forward more and more becoming almost a near foot off his chest. His t shirt ripped down the front as they continue to swell up and out revealing his solid abs underneath, the once lithe 4 pack now becoming a solid six. Chris continued to moan, "ooo...i feel....good..." he said in hushed breaths as his body continued to swell out. Biceps bulging out along with his shoulders breaking down the sleeve as his soccerball sized bicep flexed on his arm. Not to forget his lower half as in tandem his legs bulged wider and wider, shredding and ripping into the shorts he wore, his ass ripping into the back of the shorts as well revealing his straining underwear. His bulge swelled within its cloth confines till with a loud pop and a wet slap his foot-long cock laid bare on his stomach, throbbing and pulsing with euphoric pleasure on his muscular stomach. His nuts round like tennis balls just below held the overproducing cum that was oozing out of his cock tip as Chris continued to moan and buck his hips. "o-ooh...ooh..." Chris moaned more, hip bucking as he opened up his eyes to look at his newly grown body. His eyes taking in the information but not really processing but a coy smile crossing his lips as he still enjoyed what he saw. "ooh...wait till Nate see's me..." He moans as he continues to inch bigger all around even in height as well reaching 5'9 taking up most of his boyish bed. He grabs his cock pumping it on instinct alone as he continues to grow bigger and bigger, his body sliding across his bed, his back arching as the pleasure reaches new heights till finally he cums hard into onto himself. His thick seed shooting as load after load drenches his muscular body. A satisfied sigh leaving his lips as he reaches a moment of bliss before opening his eye's to see his nude body.
"w-woah!!" Chris shouts in surprise as he feels up his pecs then his newfound 8 pack abs, he stands up to then look at himself in the mirror that hung on his door. "I-i look like a regular athlete,im probably as big as nate now..if not bigger" He says flexing his naked body in the mirror enjoying the sight of every inch of his massive body. His foot an a half long cock dangling infront of him with balls as big as small melons hung below. His thick legs wrapped in muscle with nice calves to boot and going back up to his massive pecs, flexing his biceps again that was as big as bowling balls and hard as them too. "hehe..definitely maybe bigger" Chris praises himself on his size. Altho now there was a question about his new found nudity, Chris sauntered to his dresser and opened it up pulling out a pair of undies. "hmm.. was i always this small..." Chris questions as he examines the pair of undergarments , barely even able to get them up one of his muscular legs now he sighs as he realizes he might need something new...or wear nothing at all. As fun as that later thought might be he would still need to wear at least something unless he's still a growing boy.
Chris opens his door and checks around , seeing if anybody was out there, lucky for him he can still hear his brother washing the dishes downstairs after their pizza lunch. Thinking about it made him wonder if there was any leftover, but he pushed that thought down as he needed some clothing before he showed himself. He snuck down the hallway his erect cock still dangling left and right dripping pre-cum along the way. A slight flush of embarrassment and arousal filling him as he feels the need growing need to have another session in the hallway, but he knew better as he snuck into his brother's room. Closing the door as gently as he could to begin his search for a spare outfit for himself, but to his surprise none of Nate's boxers would fit to well with the hot rod that dangled between his legs. He manage to slip em up and on but that schlong still throbs erect through one of the legs, ripping itself through. Next up was a shirt that he manage to slip on but it was tight and left a little room at the stomach his muscles countering the few inches that Nate still had on him. "and Nate bigger than dad, if I can barely fit into his clothes then...I'm really a big boy.." Chris says with a swelling sense of excitement pulsing in his heart.
However it was a feeling shortlived as he turned to see, looking down at him in surprise, Chris's head at about chin height to his older brother but the massive muscles he held split that difference as Nate looks on him in surprise. There was a moment of pure silence between the two, Nate reaches out and feels Chris's pecs feeling the heat and sheer hard muscle underneath his own tight tank top. Chris lets out a gasp causing Nate to pull his hand away quickly, "a-ah...i must be dreaming..." Nate says before he continues to look at Chris who smiles back at him. "Yes thats it...im dreaming..well Chris you can wear my clothes.." He continues as he chuckles nervously. "Really!! i can..your not mad?" Chris says as he grabs his brother, his still erect dick touching Nates stomach, "U-uh..sure..yeah..your a growing boy after all..." Nate says chuckling nervously. Still unable to believe whats going on, touching Chris's cock to push it away causing the younger boy to moan and shutter causing another bout of pre to spurt out its head. "S-soo...just um..." Nate says as he looks at his pre-covered hand he looks to Chris who is still moaning and panting shuttering in delight. Chris opens his eyes "y-yeah..." he manages to respond as his hand slides slowly to his cock , slowly pumping it causing boyish moans to fill the room. "um...when would you like...to do later..." Nate says getting side tracked ever so slightly, if this was a dream for him it was very very realistic. The boyish moans, the sweat coming off his brother and the pumping of that massive cock was oh too arousing as his free hand reached out and touched Chris's cock head. The boy lets out a louder moan, euphoria wrapping his body in a comfortable blanket, pre oozing onto Nates hand as he manages to squeeze and rub the tip. Chris's meaty rod throbbing in his hand but thats not all as he feels it swell ever so slightly and looking at Chris his feelings were met with the realization that his brother was growing bigger...and bigger. His body slowly inching up and swelling out as muscle and body grow all around, Nates clothes failng to keep Chris's body contained as they rip to shred and the boy just laughs as he moans to swell even further. Before he was close to Nates height and now he was surpassing it by a few inches reaching 6'4 and still gets bigger and bigger. The boy gods body closer to body builder in musculature as he continues to grow higher and higher. It wasnt until Chris hit 7 ft tall he was showing signs of slowing, then a roar as his climax followed suite shooting his thick seed all over the room. Nate is sent flying backwards , flung into the door and onto the ground as he finds himself covered in boy spunk.
Chris stands before him at 7'4 looking down on him with a satisfied smile as if a long forgotten itch was just scratched, his 3ft long cock with pumpkin sized balls that dangled just above Nates head as he sat on the floor. Nate clung hard onto his pants feeling his own hard on pulse and shoot at the sight , shuttering as he had a delightful cum of his own before he took a moment to excuse himself into his bathroom. " This has to be my craziest dream yet..." Nate thought to himself screaming on all cylinders for the unbelievable course of events that were happening before him. His brother just grew even bigger before him and is now bigger than him in more ways than one. Nate peaks open the door to see Chris had slumped over on his bed eyes half lidded as if he was about to sleep but just not yet as he flexes a bit too. He opens the door fully seeing Chris's eyes look at him then smile again proudly, if this wasnt a dream he would be freaking out, However Nates delusions were wrong and this was all real. "I-imma go...shower...and maybe you should too..." Nate suggested for the both of them to get cleaned up. Chris obliges as he gets off of Nates bed causing the frame to creak immensely. Followed by he barely getting himself out of the room, his massive muscles taking up the entire doorway now he had to squeeze in sideways just to get through. Once he did Nate could hear the thumps of Chris's feet as he sauntered back to his room.
However what does Chris do.
