So you fucked the girl you wanted to fuck so now just leave your bitchy gf your "friend" and his bitchy gf (actually keep fucking her from time to time if you want, who cares at this point).
I kinda feel bad for the Mc because even though he isn't clean himself I still feel like he was kinda dragged into all that. Like he was fantasising on his friend's gf but in the end he wasn't trying to make it happen. Unlike his gf who was quite easily persuaded by the mc's friend who isn't a really good friend imo with his quite unhealthy kink relation wise.
So yeah the guy had a gf and a friend and now I wonder what he has left.
