A married woman heading to a love hotel is destined to be trained at an SM circle meetup hosted by a man. In the room, the organizer and another man who had already arrived were drinking beer and preparing. Taking a rope in hand, the man humiliates the married woman, binding her tightly over her clothes and repeatedly fondling her. As her switch is gradually flipped, her arousal intensifies with the situation, until finally her mouth is forced open and her throat is probed with fingers. With tears in her eyes and drool dripping from her mouth, the woman still feels pleasure from the act. Soon, the wife receives deep throat from the man... This entire sequence leads to an intense, erotic development that shakes both her mind and body.
