Jon wished his mother would look like he did at the moment, and then when the moment passed, he wished he had his original body back as it was just prior to before wishing with the stone had changed it. Unfortunately, wishes couldn't be reversed, so Jon's current porn star form remained.
Soon after, his mom bursted into the room, with her new boobs in her hands. "Thank god you haven't changed, Jon! But I don't understand why I look like this and have these!"
Jon wondered if he should tell his mom about the wishing stone, then decided that it would be best to tell her. "It's because of a wish, Mom."
"A wish? You made a wish for me to have gigantic breasts? Why?!"
"Because you did it to me," Jon said. He thought that it would be obvious to her. But then he remembered the wish he made just before she bursted into his bedroom. He had wished that his mom wouldn't notice anything wrong with him. That way he wouldn't need to explain too much. But, of course, he was telling her about the stone now anyway, so that wish didn't really matter.
"What are you talking about?" his mom asked. "Jon, you've always had large breasts. And up until now, you seemed to like them."
"Mom ..." What was he going to say? Maybe it was a bad idea telling her about the wishing stone, afterall. Wait a minute, Jon thought. I haven't told her about the stone. Just about the wishing part. I can still keep her from knowing. "Mom, I just wished that you could have large breasts like me. I really like them and I thought you'd like them too," Jon lied. "I don't know how it came true."
"Well, I don't either. But I guess I'm stuck with them now. Nothing to do but buy new clothes. I can't wear what I have with these giant things."
She left the bedroom, leaving Jon sitting on his bed. He picked up the stone and wondered if he should make a few more wishes. Maybe he could figure out a way to get himself back to normal.
