Considering the stockings fake-out, I am actually inclined to support your thought here. Not that it was done to fuck with you, but that he decided to delay getting that sweet Josy ass.
It's not NTR if it's not someone you're actively involved with. Until the end up episode 8 all you're doing is casual fucking, and you don't see it happening with the other girls, which is the entire point.
Do I want to see it? Nope. One cock is enough, unless for some reason MC goes in for a devil's threesome somewhere along the way. While I think Jacob is more deserving, we've already seen Derek naked, it may as well be him. Anybody crying NTR just because there's acknowledgement that women have sex lives is just being a retard. May as well declare that it's NTR because Nicole already has a child for fuck's sake.
Who the fuck is "Dale"?
