Kohaku is a dominatrix at an SM club. One day, a man who is training her as a masochist at the club asks her if she would like to become his exclusive dominatrix. Even though the play is over, Kohaku refuses the man's offer, speaking in a way that sounds like he is speaking to a masochist. The man gets angry and calls his friends to the club, holds down Kohaku, makes her smell a drug, and puts her to sleep. When Kohaku wakes up, her hands are tied, and she expresses her anger at the situation, but it is too late, and she ends up being subjected to the pleasure torture of the men who look at her with a relaxed expression! At the beginning, she resists with a strong tone like a dominatrix, but her body, which is actually more sensitive than most, reacts violently contrary to her words, and her clit is instantly rock hard! Unable to hold back any longer, she accepts the men's assault, and from then on, her body arches back, her body convulsing, she screams as she orgasms over and over again, until she even begs, "Please let me come!!"
