I've been dreading it since his introduction, but I really hope he doesn't end up letting his friend do things to them. "It feels good, I want to share this with you" or whatever. Also, disappointed in how much he's become such a sex maniac. I was defending him at the start since he really didn't know anything and was never taught a thing about the opposite sex, but now he knows full well what he's doing and practically manipulates them into doing what he wants. Though to be fair, the aunt is also a complete moron.
Still, I enjoy the read anyway and I'm always looking forward to see what happens next.
