A beautiful, seemingly maternal housekeeper named Satomi Mioka arrives at a middle-aged man's home, but her kindness hides a compulsive desire to dominate men and keep them drowning in pleasure. After his harassment sparks their twisted relationship, she strips him naked in the kitchen and reverses their positions: she becomes the master while he does the housework. She uses him whenever the mood strikes, confines him inside his own home, and forces him to watch NTR sex. Within days, she has learned every one of his kinks and taken complete control of both the man and his house.
