A documentary-style work depicting a real-life M-male torture circle run by dominant women in Tokyo. Three sadistic women gather and immediately start slapping middle-aged men who signed up, shouting "There are no rules!" The men gradually become mere playthings for the women's amusement. These male masochists are reduced to nothing more than experimental subjects. The amateur women cruelly torture penises until they bleed, laughing hysterically. They burn the men's genitals and burst into laughter. This is the brutal reality of an amateur S-girls' gathering, a level of cruelty impossible to experience even in professional BDSM clubs.
