A 25-year-old married woman, dissatisfied with her mundane sex life with her husband, begins seeking new pleasures through a master-servant relationship. Under strict training, she screams uncontrollably—unlike the composed civil servant she appears to be—becomes wildly aroused surrounded by cocks, and obediently drools while using remote-controlled vibrators and other toys. However, her discipline remains incomplete; she still urinates recklessly in public and squirts without permission, constantly troubling her handler. Perhaps through deeper training and tighter control, even greater pleasure and submission can be drawn from her.
