Airi Takasaka is 28 years old and works at a girls' bar in Tokyo. In college, she was in a relationship where she experienced BDSM-style training, and even after the breakup, she can't forget those memories. She has yet to find someone who can satisfy the masochistic desires hidden deep within her. Then comes a man who takes firm control of her body—yanking her hair, spanking her ass, verbally degrading her with filthy words, and repeatedly slapping her face. Though treated roughly, she feels pitiful, and that self-pity arouses her deeply. Seeing the man become excited from tormenting her, Airi becomes genuinely aroused in return. As a true female masochist, she surrenders her body and mind completely to his domination.
