Yumi serves as chairwoman of a small neighborhood association. Her husband, head of a prominent local family, was expected to take the role but was too busy, leaving the responsibility to her. Yumi still works hard and earns respect as a capable leader, but her husband's refusal to satisfy her in bed leaves her increasingly frustrated. One day she begins sleeping with men from the neighborhood, and that first affair opens the door to a life of filthy encounters in which the local workers become her personal sex pets.
