Yurina Wakabayashi visits Kasumi Hourai, a bondage master and AV director, hoping to appear in her works. Declaring herself a masochist, Yurina eagerly anticipates hard-core play, but Kasumi pushes Yurina's limits with humiliation and pleasure far beyond her imagination. Kasumi doesn't care if Yurina enjoys it; she wonders how to capture genuine expressions. Through various plays and psychological warfare, Kasumi draws out Yurina's charm. She uses clothespins struck by a whip while suspending Yurina for enema play, testing how much Yurina can endure.
