Thanks, but its not that, i remember that its not ntr because the old guy actually asks the protagonist to bone his wife.
Yeah, that's what happens in this - Hitozuma Miyuki-san ni Otto Kounin de Mainichi Tanetsuke Sex
It's got a NTR tag, but it's not. Her old husband asks for the main guy to bone his wife and then she falls for him. Just another example of NTR being misused.
