thats what makes rape so terrible. your body reacts like that and you (your mind) have no control over your reactions, so you orgasm against your will. its important to focus on the eyes she has and not the flush cheeks
it would have been wrong if she looked like she had a stone face and that it didn't affect her.
(its vile definitely but the "you like it don't you" is partially true. your body reacts like it does, its just a chemical response)
