"I wish all girls wanted to touch my penis," Jon muttered, as he fantasized about Karyn caressing his sensitive new member, as she did when she wished for her blond hair and large breasts.
New member.
That thought snapped Jon out of it. What had he done? His penis granted wishes. If girls suddenly wanted to touch it, they could make as many wishes as they wanted; he'd never be able to stop them. And he couldn't wish for them not to touch it, because that would be a contradiction to the wish he had just made.
He grabbed his forehead and sighed, wondering how he was going to go to school now, with every girl in sight trying to shove their hand down his pants.
