In Tokyo's M Ward, the "Women's Psychology Research Institute" operates publicly as a domestic violence counseling center. In reality, it is a corrupt organization run by perverted instructors who subject married women to extreme cruel training designed to expose their hidden masochistic desires. This time, a particularly obedient and adorable housewife came seeking help. Complaining that she was troubled by her husband's exhibitionist tendencies and felt too ashamed to face her neighbors, she agreed to undergo intense exposure training—pushed to the point where her sense of shame was completely numbed. As a result, she was fully transformed into a masochistic sex slave, and the recorded footage was destined to be sold on the black market.
