Takedo Nogawa is the spoiled step son of a wealthy industrialist. When he was young, he was infatuated with Yumi Okamoto, his step father s personal secretary. But as she was also his step father s personal sex toy, Yumi was off limits for Takedo.
After he gets into a traffic accident with Yukie Kitazawa, an average housewife, Takedo sees an opportunity to one-up his old man. Per a contract drawn up by Yumi, Takedo allows Yukie to waive her legal fees if she becomes his sex slave.
Not to be outdone, the elder Nogawa sicks his secretary on Yukie s teenage step daughters, using the contract to exploit them for his own twisted desires. A sick game ensues as step father and step son compete to strip the Kitazawa women of their dignity.
