I have always understood it to be where one person allows their partner to cheat on them and even gets off on it, much like a cuckold. If what you say is true however, than as far as I am concerned it is FAR too generalized of a term for me to ever use. If I ever create a game with cheating in it of any sort, I won't use that term nor will I ever tag it with it. Period. I don't understand why people get so uptight about it, it's just another kink that some like, some do not... don't like it, don't play it, move along, but STFU about it. If I don't see the term "NTR" again, it will be too soon!
