An office lady attends a self-defense workshop, only to become the target of a gang of delinquents who subject her to sexual harassment and cruel treatment. Living in Shinagawa Ward, she has a personality that tends to attract unwanted male attention, so she undergoes counseling and participates in the session wearing training attire. She seriously learns the techniques demonstrated by the two male instructors, repeatedly practicing how to respond when grabbed by the upper body or restrained from behind in joint locks. Amidst actual sexual harassment, her breasts and groin are stimulated, causing her body to grow hot despite her inability to resist. She is tormented with electric massagers and vibrators, enduring endless deep throating and repeated orgasms. The video includes standing doggy style, cowgirl position, and creampie scenes.
