Lenore, despite all her inexperience, had at least spoken to people enough about sex to know what generally went down. It wasn't research or anything, she didn't cosmo that shit, but when you had a lot of sexually active friends (and really, everyone she used to talk to was sexually active) you tended to get a better understanding.

She demanded, still laughing a little as he came back over to her. Yep. Allllll that was hers.
