A housewife seemingly enjoying a family drive on her day off, but in reality, she has another 'master' that her husband knows nothing about... She feels guilty towards her kind husband, but the other master subjects her to sexual training, making it impossible for her to resist. Today, even during the family drive, completely ignoring the situation, or perhaps enjoying it, she is summoned by a phone call from her master to a convenient multi-purpose public restroom.
