In f95 colloquial terminology ntr is an umbrella term for any instance where the mc, sometimes the playable character, doesn't have sex while other characters do. NTR refers to an extended family of fetishes if you will. Voyeurism is part of it, your mother having sex with your father while conceiving you is ntr, raising a daughter is ntr, etc. The more you know.
I just... what? Is this what people here think NTR is? Literally any sex that occurs without the MC being involved? That's not how it works. NTR is a pretty specific kink.
Saying that NTR = all sex that occurs without the MC is like saying the Lesbian tag is appropriate for every game that has gay characters, even if there are no women in the game. Or like saying the Vaginal Sex tag is fine for strictly lesbian games that don't include penetration. Hey, there's a vagina involved so it must be the same, right?
Tags and genres exist for a reason, don't try to muddy the waters by conflating genres with each other and assuming everyone agrees with the idea of throwing every categorization into a blender. NTR is not the same as cheating and is certainly not the same as pimping.
As far as I've played in this game, there is absolutely no NTR whatsoever to be found here.
