In high school, her nickname was "Big Boobs," and now she runs a massage parlor. A client falls head over heels for her at first sight. Inside the shop, alongside Big Boobs, there are also slender employees, and the sight of her cleavage during treatment is irresistible. When the client confesses his feelings, Big Boobs starts giving him relaxing body rubs. It turns out one of the staff members is a cock enthusiast—she barges in on him while bathing, jerking him off with a handjob, and even gives him a blowjob during the massage. Their actions are caught by a classmate, leading to a twist where having sex with Big Boobs might actually become a reality.
