変態病棟 SM診療室

《変態病棟 SM診療室》的剧情介绍：
Japanese cult director Hisayasu Sato made this slow-moving pinku-eiga story for Shintoho, one of two for the studio that year among his four 1989 releases. This is a standard tale of an abusive psychologist (Kazuhiro Sano) whose S&M sexplay becomes too much for his wife (Kiyomi Ito). She leaves him, but happiness arrives in the form of her masochistic twin sister (Ito again), who is perfectly content to be Sano's whipping-girl.
