A married woman enjoying a peaceful family drive, but secretly she's been involved with another man behind her husband's back. Though she feels guilty toward her kind husband, her relationship with this other man—whom she calls "Master"—has become deeply entrenched through intense sexual training, leaving her unable to resist. Even while out on a drive with her family, she receives a sudden call from him and immediately heads to a public restroom without hesitation, almost as if she's enjoying it. Their encounter there only tightens the bond between them further.
