A housekeeper works in a household with only two men. She is very earnest and enthusiastic, working hard for her husband. One day, the housekeeper accidentally spills tea on the husband's crotch. Panicked, the housekeeper becomes worried about the burn and begins to remove the husband's pants and treat him. Seeing her actions, the husband's dirty fantasies grow, and he starts making one erotic request after another to the housekeeper. However, the housekeeper doesn't show any signs of displeasure, simply saying, "Yes, I understand," and fulfilling the master's requests.
