Mods have been going back and forth on the tag several times. There are a bunch of sort-of NTR-like scenes.
The official F95zone definition of NTR is something like "a person the MC is involved with fucking in front of the MC in a scene that is designed to cause jealousy". The clearest examples of this, in my opinion:
1) After the first erotic scenes (before sex, I think) with the mother, the MC walks in on the abusive father having sex with the mother. The mother then belittles the MC and says that she went back to the father because the MC was not "man enough". Classic NTR aside from them (sort-of) being husband and wife. (spoilers)
2) When the MC first enters the sex world, he walks in on one of the possible love interests having a gang bang. One option is to get so angry, he runs into the room in a rage and tries to attack the group. At that point, the MC does not know that this is not the love interest.
The game had been without NTR tag for several years, but 1-2 years ago mods changed it. It might be because of another scene, but I don’t think any new scene like that has appeared since.
So I even agree with the etiquette for the world of sex, because if at that moment you have already finished this character's story they are already "boyfriends" in the normal world, then it would be something like Netorare, but then you get to know the world of sex and you know that There everyone belongs to everyone, in other words it wouldn't be a betrayal but everyone can have fun with anyone there.
As for "mother and father", this moment of sex only happens if you don't spend an afternoon with her, then on the same night you go to the living room and she says this to the MC, but not to belittle him, but rather to put it in in his head that he has to be the man of the house, since he still considers himself a kid, and this helps him mature, until after he punches his "father" his mother apologizes for what she said and then they start to be lovers because of their "father's" things, that is, it is the MC who is "stealing" her from her "father", and according to DEV this scene was created with the intention of making the MC grow up and take control of the situation. life and family, which is why he is not considered NTR by them.
Another thing that could be considered is the "glory hole" on the beach, but you see that everyone saw it there in that place and the MC can do as much for him as for other guys and the MC doesn't even care about that, because He knows that later they will come after him to be with him alone.
In other words, from what I've played so far I haven't seen anything about netorare and I'm very against it and nothing has offended me in relation to it, we can say that it has a beginning of Netori, but for that to happen the "mother" has to ask the "father" for a divorce and then be left alone with the MC.
