Honami, the housekeeper for the Sugaura family, becomes captivated by an adult DVD she discovers in her employer's son Shigeru's room. Despite being in the middle of her duties, she gives in to arousal and masturbates—resulting in an uncontrollable, heavy urinary accident that soaks her panties. Faced with this unexpected situation, Honami is forced to continue working without underwear. However, her shapely bare ass, peeking out beneath her skirt, is soon spotted by the master of the house. What follows is a humiliating escalation, as he remarks, "You'll come without panties again tomorrow, right?" From that moment on, Honami's days as a live-ass housekeeper plunge into an unending series of torment and shame.
