The story is about a soft spoken, high school teacher who takes vengeance into his own hands at night by becoming Rape Man. He and his Uncle are partners in Rape Service. Where they offer rape as a means of Justice. They take their earned money through Rape Service and donate all of it to an orphanage which our hero grew up in. Their motto is "Righting Wrongs Through Penetration". (imdb)

Cult filmmaker Hisayasu Sato achieved a bizarre sort of success with his 1990 film Uma To Onna To Inu, leading him to return to the same tainted well with this warped look at a woman who lives in the middle of nowhere with a horse for a lover. The horse is also her best friend, and they communicate through telepathy as well as engage in intimate acts too unnatural to describe here. Unfortunately for all concerned, some photographers and models show up to upset the idyllic romance. (All Movie Guide)

This softcore effort from cult pinku-eiga director Hisayasu Sato concerns the perfect couple. Of course, they don't know that they're the perfect couple because they each keep a "terrible" secret from the other. This prevents them from enjoying a normal sex life. The husband is impotent unless he can watch another couple having sex, and the wife pleasures herself to thoughts of being raped while someone else watches...
