Since Jon was horny the first thing the thought of becoming a person that was hung like a horse. His dick swelled in size and was soon as large as his forearm.
"Oh shit this is awesome." he said. Making sure the bathroom door was locked, Jon began to take a shower. He imagined becoming a person with huge boobs and extremely feminine hands like Sara from school and instantly he had hands and breasts just like Sara.
He alternated between feeling his extremely sensitive titties and masturbating with his huge cock. With Sara's hands however it felt more like getting a hand job than actually masturbating. "Oh god!" he exclaimed "This feels sooo good."
After about a half hour or so, the water started to turn cold and he got out shivering. No longer horny, he felt slightly disturbed by the boobs as big as his head and a limp penis that fell down to his knees. He imagined him being his normal self. He dried off, dressed, grabbed the rock and went back to his room.
Jon laid on his bed, looking at the ceiling, thinking. What would be the best way to use this new power? Obviously he could use it for his own sexual entertainment, but what else? Should he fight crime? Obtain a new spiritual outlook on life? Help the homeless? Get revenge?
Jon grinned.
