At a certain insurance company's sales office, the chief Momona is rampant with unreasonable power harassment. One day, for unknown reasons, Momona turns into a woman and comes to work. She continues to harass employees as usual, but the employees can't help but fight back. She is unable to withstand the man's seriousness and is tricked. "It won't make me pregnant, so it's fine." From that day on, her days as an outlet for the employees' resentment and sexual desires began.
