What >>4959 said, but also, NTR applies to more general cases of that sort of sexual humiliation, including when you haven't even asked the girl out yet, or even some guy fucking your mother. I mean, getting a new stepdad isn't necessarily NTR, but when you have a new stepdad who's actually the classmate you were bullying earlier and now that he has a mind-control app on his phone he's taking revenge by fucking your mum and making you watch, that's NTR.
