To celebrate the birthday of Sano, her husband's friend, Reiko visits his home. While her husband has yet to arrive, Sano begins talking over tea about a woman he's secretly been in love with for a long time. As he reveals that the woman is Reiko herself, he overpowers her—drugged tea taking effect. Reiko is bound tightly with jute rope, deprived of water and the ability to relieve her bladder, pushed to the limits of hunger and arousal. In this helpless state, Sano claims her completely. Temptation and domination intertwine as Reiko's mind and body are torn between resistance and surrender. A dense, intense narrative unfolds, driven by emotional conflict and the raw power of control.
