>>55680474That's not even NTR at that point, it's just cheating.
NTR is cuckoldry, the cuck has to be aware and perhaps even present for the fetish to apply. NTR isn't just watching your SO get railed in front of you either, there's the moral degradation, inferiority, seeing your SO get corrupted. That's what makes it NTR.
It's a shit fetish, anyway.
