Mayu was planning to ask her part-time job for an advance to help her husband who was in financial trouble, but the manager was absent and she embezzled the sales without permission. The act was caught on security camera and she was questioned by the manager, who is also a good friend of hers. The manager, who is a virgin, could not hide his disappointment at what happened just when he wanted to ask for advice on how to treat his first girlfriend. Mayu, who wants to somehow get him to overlook it, seduces him by saying that she will teach him how to please a woman, and he ends up making her cum over and over again with his virgin dick, even making her squirt.
