After starting work as a bunny girl at a concept café, Shizuku reaches the limit of her bladder during her manager's seemingly endless training. Her request to use the bathroom is refused, and she wets herself in front of him. The replacement outfit he gives her is an indecent reverse-bunny costume with a diaper covering her exposed crotch. Still confused, she repeatedly loses control as pleasure builds. This niche production focuses on urine and diapers, including wetting inside the diaper and sex with the diaper pulled aside.
