Airi, 28 years old, works at a girls' bar in Tokyo. She was subjected to SM-like training by her boyfriend during her student days. Even after breaking up, she can't forget what he did to her. No one appears who can satisfy her masochistic perversion. I will trample on such Airi's body. Roughly grabbing her hair, slapping her ass, abusing her with dirty words, and then a barrage of slaps. She feels sorry for herself being treated roughly, and she loves that self. A pure masochist who gets excited when she sees a man tormenting her and getting excited herself.
