Mr. and Mrs. Otomi move in next to Daisuke, a part-time worker who doesn't feel like a woman. Daisuke was annoyed by his neighbor's wife, Rina, who made a violent pant voice at night. She is an attractive married woman with a plump big butt. Daisuke peeks into her room out of nowhere and finds her gasping like a wild beast and indulging in masturbation. Unable to move on the spot due to the shocking sight, Rina notices something strange and finds out that she is peeping. The condition faced by Daisuke is to go along with Rina's libido.
