Only scene I was shocked that didn't happen was the friend didn't try to fuck the MC's mom(if I remember right). I mean, he tried to exploit his girlfriend and did fuck his sister(?). Maybe he wasn't into milfs or it must've not fit into the story? which is understandable.
Anyway, I'll check this out. I'm looking forward the kinds of spicy scenes that can be cooked up here, since it doesn't have to follow the story.
