I usually offer routes that flip the script to some extent in my games, but they are primarily designed for players who don't mind or enjoy the NTR events. A playthrough that fully avoids such scenes may not be possible and doesn't offer much of anything else in it unfortunately.
I like NTR, but only if its optional. I like NTR games where you are supposed to try to make sure it doesn't happen, but it happens anyways because of my bad choices if that makes sceans. I'm not trying to say your game is bad, I'm trying to say your game doesn't match my tastes but that it could with some small changes.
