Ty suddenly had a crazy idea. Since he could wish for anything he wanted... he could give himself both kinds of parts. Playing with both a penis and a vagina... no one had ever had that experience before!
He took a deep breath, and grinned. "I wish that I had a vagina in addition to my cock." He felt an intense tingling between his legs. His penis and testicles seemed to move up slightly, until a flat space had formed between his balls and his butt. He gasped as he felt the skin in that part sink in, his guts shifting to make room for his internal feminine organs, as the most intense feeling emerged in a tiny nubbin right at the top, poking through the forming lips. The passage being carved inside him pushed almost deeper than the length of his shaft.
The feeling, and the desires the new pussy was sending to his hormone-addled teenage mind, was too much. He reached down and began to rub his erection with his right hand, whilst his left hand sought out his new vagina and proceeded to massage his new, moist lips. As he played with himself, he jerked his hips upward to simulate the feeling of fucking a pussy, and pushed forward and back to imagine a hard cock thrusting in and out of him.
In his lustful mindset, he suddenly thought of another wish. "I wish I had another pair of arms," he moaned, and with that a pair of (feminine) arms emerged from his shoulders, and rapidly set to work satisfying his chest, pawing at the flesh and squeezing the nipples. Before long, of course, satisfying him...her?...self from three different places was too much for Ty, and he came indescribably hard, squirting his seed on his chest and clenching tightly around her fingers.
When he...she... awoke, things would be very different.
