I remembered. I recently watched the anime Gundam SEED. And there was a moment with NTR. Flay and Kira. Flay did not love Kira, she considers him an enemy, she has a husband, although it is by agreement than by love, but her husband loved her. And Flay loved her too. But because of the death of her father, everything changed dramatically. Now Flay essentially took advantage of Kira's weakness and had sex with him.
Once again, Flay did not love Kira, she hates him. But why then? Because Kira is an NTRman with a 40 cm dick? Or because Kira is just a wild type? No, he is weak. But why then? And so that he would take advantage of him and he, as if out of a sense of duty and obligation to protect, began to kill enemies.
As Flay said in her mind - Kill, kill, protect me and die.
In fact, there is little NTR moment here, but what an approach.
And no blackmail, uglibastard or NTRman with a 100 cm dick. There's even more here NTR Reverse.
As I said before, any anime, even a simple one, can be made into NTR, the main thing is the right approach and reason.
