A cute girl named Suzu visits a certain bar. There's a rumor that if Miuka, the bar's madam, takes a liking to a girl, she'll be taken to a secret room for training. After drinking a cocktail and losing consciousness, Suzu suddenly finds herself tied to a chair. Her stockings are roughly torn off, and she's tormented with a vibrator set to deny orgasm. She then endures the harsh yet pleasurable initiation of a single whip. Her nipples are twisted, her body trembling under candle wax torture. This entire series of torments is a calculated setup to achieve total domination over her.
