Just as he was about to head outside, Ty came to a sudden conclusion.
If he could change anything, including himself, why bother going out into the world as geeky Ty? Even with a little extra muscle, he was still a short and undeveloped doofus. He went back to his room and grinned at himself in the mirror. His short bowl cut hair, his wide glasses. His bare little body. He got undressed and stared at himself.
Time to fix this!
The first thing Ty did was fix his eyes so that he would never need glasses again. As his eyes came into sharp focus he tossed his glasses into the trash and smiled. Next, he willed himself to develop to the normal size for his age. He grunted and felt warm all over as his slim short body began to progress to a proper 15 year old. He groaned as his height increased, his shoulders broadened, and wisps of pubic hair began to grow out. His jaw became harder, and the muscles he had given himself grew along with him, pumping him back up into an athletic young man as he hit 5'6". Now hardly a nerd, Ty gave himself attractive thick hair and grew out his facial hair. Pleased, he flexed in the mirror and grinned wider as he saw he had gotten excited during his growth and now sported a nice 5 inch long cock.
He looked down at himself, and decided that wasn't enough. He progressed himself to 21, moaning as he pushed further, his musculature inflating to a hardened athlete now, big and bulky, and his height grew to 6'3". He looked down as his manly hairy body, thick with hard muscle, and marveled at his now six inch cock pulsating down below. He grabbed his cock, feeling it aching and throbbing, and gave it a few swift jerks up and down. His hard bicep flexed and he moaned in a deep voice, sweaty and musky.
Damn! He looked in the mirror, admiring his rough beard and long thick hair, and rubbed hands over his stiff well proportioned pecs and hard abs. His thighs and calves were bulbous powerful legs, and his tight biceps and arms were just as good as his thick hands. He looked down at his dick, now leaking pre, and grinned even wider. He gave himself an extra inch, sitting down on the edge of the bed and gasping as he felt his cock swelling. He jerked it hard, marveling at how much more sensitive it was, and grew it to eight inches long. Gasping, frantically pulling his longer more sensitive cock, Ty blew up his balls too, increasing his capacity and their own sensitivity. Now panting, Ty grew it out another inch, now sitting at a long nine inches of dick. But that wasn't enough, so he willed it longer and longer until he had a stiff and throbbing 12" of cock. With his huge balls though, the slim length was almost comical, so he began thickening it. The base of his dick swelled, slowly engulfing the length of his cock, and soon enough Ty was half as thick as a pop can. To hell with it, he gasped, practically pouring pre, and thickened his huge new sensitive cock up to the thickness of a whole can from base to tip. His huge pulsating tip flared obscenely, and it took both hands to jerk off his wild new monster. When Ty finally blew, with a loud cry, he released enough to soak the floor in front of him, splattering hot jizz all over his chest and stomach.
Gasping, developed and hung Ty rose from the bed and prepared for another warm shower.
