You know, I have nothing against NTR and, in fact, can love it if it's done in a realistic and meaningful (or at least in a really hot) way. I can understand mainly NTR game even if male protagonist is constantly and disproportionately punished for nothing (although I wouldn't play such game for long). But why on earth the author would create two routes with the same events and characters in his game and make one of those chars vanilla (slightly dominating) leaning girl in one and self-humiliation loving slut in the other is beyond me.
If you bother to create two routes at all, have the decency to make them at least partially equal in terms of quality of the content.
