A man who goes to school and works part-time to earn money for school. The place where he works is full of part-time housewives, and he often has to listen to their complaints. As he gets changed at work, as usual, he is alone with Nanami, a part-time housewife. As he listens to her complaints before work starts, the atmosphere becomes strange and she kisses him, saying, "Don't you like an old lady like me?" They even end up having sex secretly. From that day on, whenever he has free time, he continues to have sex at his part-time job every day.
