I hoped the other thread would've convinced you. I mean, seriously? She IS your sister. I could never ever do this with my brother. He's been there all the way, and I think it's been the same with you two. You were raised together, you know things about each other that just siblings know, you are brother and sister. And you slept with her? Can't believe it. I don't want to believe it, actually. Please, tell me it is a troll, please. Otherwise...this is just wrong!
