The male office worker is a perverted man with a strange fetish for women's underwear. One day, his secretary, Hazuki, discovers his secret. Noticing him trembling during work, she grows suspicious and inspects his body—only to find vibrators attached to his anus and penis. Shocked and furious, she summons him to her home. There, he faces extreme BDSM training involving blindfolds, restraints, whips, wax candles, and penis bondage fisting. As Hazuki's dominant nature emerges, the man submits to her control, experiencing both humiliation and pleasure simultaneously.
