A bar somewhere in Tokyo. It's a lawless area where SM and fetish shows are held day and night, and underground people gather to seek excitement. Haruki comes to an interview to be a bar staff member. Haruki also has tattoos on her body, and exudes a mysterious, dark aura. The owner, sensing Haruki's masochistic nature, suddenly starts throat training during the interview. With intense throat play, Haruki's masochistic nature blossoms in an instant. Throat training with toys, deep throat, restrained throat orgasm, and a piss-in-mouth enema that makes her vomit. A hard-core deep throat 3P that makes her brain juices explode. Haruki's true nature is revealed: she wants to be messed up, and to be an outlet for men's desires. She is such a masochist, and a woman with a slave constitution.
