A married woman seems to be enjoying a peaceful family drive, but in fact, she has a man who is like a "second master" to her husband. 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 instead seems to be enjoying himself, and summons her to a multi-purpose public toilet with just one phone call.
