I don't get it. What does the end mean, did he do it or did he just imagine it? In any case, that's very rape 101: not stopping even when no is said multiple times, he blames her for reacting to stimulation...yeh he's a real asshole lol. I don't know wheter I should hope he did it for real because hentai or not because it would just be a healthy rape fantasy..
@Juggernaut Santa he rape her for real. maybe the unexplained ending makes you confused, but in the next chapters the story goes on from this incident :D
