There are a ton of NTR games. It's not a particular kink I have but people fucking is (haha) and this story just got too boring by the halfway mark. Due to that I was ready for D to fuck literally anyone else, under any circumstances as long as it was her choice. I was down for her fucking anyone as long as she didn't have to go ask permission of have her dad watch/join in.
So not NTR specifically but if someone wants to call it that in this case I'll say "sure, shoulda had NTR" haha.
However, a great game that is probably my favorite VN ever on here is called "Babysitter" and has NTR that you can avoid or make happen. It's MUCH more realistic take on a young lady having multiple men wanting to fuck her and, gasp, she actually has free will and a brain to decide who she wants to fuck. Crazy idea, right? As MC you can actually NOT win the girl if you make dumb decisions.
I'm into stuff like that but it's not specifically an NTR kink. I just like good, realistic stories. NTR just happens to be in a few of the better ones.
