Airi, 28 years old, works at a girls' bar in Tokyo. During her student days, she was subjected to SM training by her boyfriend. Even after they broke up, she couldn't forget what he had done to her. No one could satisfy her masochistic tendencies. Such an Airi is trampled upon. Roughly grabbing her hair, slapping her buttocks, cursing her with filthy words, and then a series of slaps. Seeing herself being treated roughly makes her feel pitiful, but she also finds such a self endearing. Watching the man who torments her get excited makes her excited too. She is a pure masochist.
