At a certain insurance company's office, unreasonable power harassment by a group of 100 chiefs is rampant. One day, for reasons unknown, Momona comes to work transformed into a woman. The employee tries to use power harassment as usual, but the employees are unable to resist and fight back. She can't stand the man's seriousness and gets fucked. ``I won't get pregnant, so it's fine.'' From that day on, the days that become an outlet for the employee's resentment and sexual desire begin.
