At her husband’s suggestion, a devoted wife visits a nearby couples massage parlor with him. She has sworn never to betray the caring man who always puts her first. A female employee attends to her husband while male therapist Kanda handles her session, and at first everything feels completely normal. But once she lies on her back, Kanda reveals his true nature. The female employee is in on it, and with her sleeping husband on the bed beside her, the wife is forced into a humiliating folded-leg treatment position she has never even shown him.
