Respectfully, no it doesn't.
*gets on soap box*
I repeat, a partner/love interest that doesn't have sex with anyone but the MC is the only thing that 'goes against NTR'.
You are confusing 'what you like about NTR' which is narrow, with 'everything that NTR can be' which is broad. I doesn't matter how common or uncommon it is. As long as the FMC is getting fucked by a third party, then it's NTR. How it starts, how it progress, and how it ends are completely unimportant and can be literally anything you can think of. Telling someone that what they like 'goes against NTR' just because it deviates from a common trope is just more "stop liking what I don't like" logic.
It's like telling people who like lesbian NTR that it 'goes against NTR' because lesbian NTR is rare and you think NTR can only happen with a dick.
It's like telling people who like BSS or MomNTR that it 'goes against NTR' because you think NTR can only happen in a committed relationship.
It's like telling people that like NTR Type-C that it 'goes against NTR' because the girl never falls or betrays the MC.
When you do this you're effectively reducing an entire genre to the narrow part of it that you can see and enjoy while invalidating anyone that is capable of seeing and enjoying more.
And this is why the genre is slowly dying.
Edit: A word.
Maybe I should've rephrased it better. You're right, Revenge doesn't go AGAINST the definition of the Genre, and can even compliment it in fact, but it rarely happens, and with Cuckold/Corruption being literally 99% of the Content anyways, what the fuck is the point of reading and whining about all of that 99% JUST to see the Revenge Ending?
The Genre sure as shit isn't dying because of this, NTR is literally one of the most popular Sexual Topics in porn (if not controversial but that's besides the point).
NTR's definition is literally:
"The NTR in the title stands for netorare, which translates to "
cheating" in Japanese. While the term is similar to cuckold ("husband of an adulterous wife") the couples involved here are not in a marital affair. In the story, the two girls cheat on their boyfriends by doing things with each other."
Does this set up for Revenge? Sure, it can. But that doesn't mean every NTR
needs or should be expected to have a Revenge Ending. The focus is Cheating, and there for you should expect Cheating as its primary focus and nothing else, which is why that applies to 90% of NTR in the first place, and why there's a lack of Revenge.
Whether there's Revenge, Anal, Lesbians, you name it, that's all just a bonus surprise that can apply to pretty much anything. Hating the Genre with 99% Cheating because it doesn't feature a whimsical Revenge Ending is just setting yourself up for a bad time, you might as well go somewhere else if that's your only value in the Genre.
