This work is a documentary featuring videos sent to a magazine editorial office by an SM circle. Their core principle is "extreme male supremacy," positioning women as male property and sexual tools, aiming to secretly realize and sustain this culture in modern Japan. The footage documents four women, each strictly trained by their respective owners. Married woman Ai undergoes anal training and toilet object conditioning; office lady Mina experiences whipping and bareback creampie sex; Keiko has lived for over ten years as a human livestock; and college student Ryoko voluntarily seeks a life as a sex slave. The film depicts female domination through close examination of vaginal tightness, anal shape, servicing mouths, and nipple sensitivity. Themes include humiliating lesbian shows, sandwich servicing, anal tug-of-war, anal sex, punishment by whipping followed by reward sex, slave bondage, piss diapers, oral servicing, and exploring differences between submissive women. This is a documentary intended for amateur fetish enthusiasts. Viewer discretion is strongly advised.
