A married woman torn between shame and taboo desires fulfills her husband's cuckolding fantasy by approaching the organizer of a swinging club. This time, the target is Sae (23), a submissive young wife in her second year of marriage. Persuaded to do it for her husband's sake, she reluctantly agrees to be taken by another man. Though she tries to resist during foreplay, her body betrays her, dripping with arousal. Once penetrated, her endurance collapses completely, erupting into loud, desperate moans. Afterward, while being vibrated, she calls her husband to report everything—only to be overwhelmed by pleasure once again. As she accepts the man's cock a second time, she wildly grinds her hips, and during doggystyle, she thrashes uncontrollably until her legs give out. Every moment captures the shocking conflict between her dignity as a wife and her hidden desires.
