Cuck path is there for the sake of it and pleasing the fans. Logic has nothing to do with it. Most common NTR trope borders around rape, humiliation, blackmail and coercion, which to be honest gets tiring and bland pretty fast. But as they say different strokes for different folks. I don't get the cheating kink tbh, it's probably fun to read, watch and hear about it, if it has not happened to you personally. On the other hand, this shit hits like a fucking heavy gut punch.
