If that's the case then NTR is just a weeb name for cheating lol. But yeah, alot of the material tends to be hilariously written. After all the writer assumes you're there to wank, not to grip yourself with a sexy drama.
I've spent hours with a friend talking and laughing about different retarded tropes in NTR porn. I find the "drug is actually a Placebo" trope particularly hilarious as the housewife tries to cope with the situation she had a million ways to avoid with the idea that a pill is making her do it
Hahaha, no not really. Just a looooot of people tends to generalize everything. "MC's wife/girlfriend/childhood friend has feelings for him cheated on him is called NTR. So that means cheating period = NTR." is the overall tone I see with a lot people now days, but it was more specific in the past. A few things that is not actually NTR that people label as NTR are:
1. The non-dating/married love interest doesn't like the MC romantically. Friend-zoned MC basically.
2. The dating/married love interest openly treats the MC with disdain. Only with cause of money/status/etc and doesn't hide it.
3. The love interest seeks out and/or seduces other people willingly. This is just plain cheating.
The NTR situations I fucking love to hate is the "Hey I took a picture of you peeing, changing clothes or some other mundane activity. If you don't want me to upload this to internet, totally putting myself in a high risk....you'll do actual scandalous stuff with me, as I still have the camera/phone I used to take the initial photo, instead of doing the sensible thing like calling the police. You can trust me that I won't take additional pictures and constantly ask you to go further and further with the sexual acts. Oh, and I'll totally not secretly send a copy of those actions to your boyfriend/husband for the lols." thing or the "You're a highly trained warrior/assassin and I'm just an average joe who maybe worked out once in my entire life but by the power of horny alone I can out maneuver and overpower you despite the fact that you earlier easily took down someone/thing that could easily destroy me." thing.
