In walked Oliver. Sweaty and carrying a huge bulge in his pants. The two immediately began snogging. Their hands explored each other's bodies and all was fine until:

"Ollie, you still owe me."

"Why?"

"How could you forget? We won!"

"I was only kidding."

"You promised me anything within reason."

"I did."

"Take my virginity!"

Oliver was shocked and ran out the door. Harry had never seen anyone run so fast.
