Muv Luv Altnerative's NTR Rape scene.
I think the point of the scene was to disturb viewers, so people who are disturbed are doing it right.
I just thought the whole scene was stupid. Instead of feeling any kind of emotion for the character, I couldn't control my eyes from rolling. I felt so embarrassed for the character who was supposed to be beyond tragic, in a truly tragic VN. CTRL all the way through. It was such a forced scene and totally unnecessary. I had a hard time believing terrifying aliens would do something so cliche in bad hentais rather than the perverse minds of VN writers.
