A married woman seems to be enjoying a family drive on her day off, but in fact, her husband has a man who is like a "second master" to her... She feels sorry for her kind husband, but he has given her sexual training, and they are in a relationship where she cannot resist him... Today, again, in the middle of a family drive, her master calls her, not caring at all, and as if he is enjoying it, and calls her to a multi-purpose public restroom with just one phone call.
