Women's bodies hold unimaginable potential. This work explores the abnormal impulse to transform such bodies into forms beyond normal conception, reshaping them into more erotic and depraved beings. It portrays the relationship between individuals driven by sadistic desires and masochistic women who resonate with those desires. The film presents an extremely unique worldview centered around the theme of anal stretching.
Case 1 follows Yuki (pseudonym), a housewife living in the metropolitan area, who is being trained by a man known as Kōmon as an "anal animal." Having lost her father at a young age and developed a father complex, Yuki's past intertwines with her masochism, allowing her to find existential meaning through Kōmon's anal training. Starting from having no prior anal experience, she has undergone progressive stretching and continues to be trained to this day.
As an "anal animal," Yuki claims she can no longer live without her master. Her words reveal deep dependency and pleasure. She feels her body has been completely dominated and that she has been reborn into a new existence.
Case 2 depicts Setsuko (pseudonym), a former teacher who became an anal slave after being masochistically trained by her former student. She views her own body as merely "three holes—the mouth, pussy, and anus"—instruments designed solely to provide male pleasure. Once a respected educator, years of training have transformed her into a rental slave capable of serving any man's cock.
Even past the age of forty, Setsuko daily pleasures herself through anal masturbation. Her body has already evolved into something beyond human limits.
Through the theme of anal expansion, this work is an extremely unique exploration of human relationships, bodily freedom, and the boundaries of pleasure.
