"Tempting," said Cho, "but my stance hasn't changed." It was too bad, but Padma and I never expected any less.

Padma's head began to move again up and down. Cho Chang opened up her legs further, and was much less discrete in touching herself.

I nearly was asleep minutes after, only waking up to hear Cho and Padma talking amongst themselves. I needed the rest though, the school year was going to be a testing one.
