Mao, a female employee at a certain company, is actually a member of a high-class M erotic club, where she plays with the bodies of perverted M men every night... and even their anuses. She is a hidden slut, and not satisfied with that, she keeps a male colleague as a pet and secretly enjoys slut play in the office during the day. One day, Mao's boss, the department head, finds an M erotic girl who looks just like Mao on a sex site... A man who visits the M erotic club where Mao works as a customer is 'convex' with Mao's obscene techniques and violated to the bone!
