"Wow, what a screwed up family!" said Hermione. "Do you know anything else?"

Harry was feeling pretty horny now. His new power was giving him a rush and making him feel invincible. "Yes, just like I know you are too shy and ashamed to tell Ron you really want to have anal sex with him."

Hermoine gasped. "Um...uh...it's just...can we just stick to other people?"

"Sure," said Harry.
