I like how he cared about Nayeon there, best girl.
Ppl that talked about recording, it was the redhead phone, what would be the point of recording sth on it?
I think that most possible scenario would be MC baiting redhead for reverse game since that was one sided and it was no way that he could win with someone so experienced and redhead "pride" won't let her refuse.
Second possibility is that 10 minutes just passed but its less likely.
Third one even less likely, he becomes her slave for a short time but then something happens and redhead let him fuck her and she cums so much she release him of being "slave".
