A story that intensely stirs the hidden shame and sense of guilt within a married woman. To fulfill her husband's cuckolding desire, she contacts the organizer of a spouse-swapping enthusiast group. Her partner is a young, submissive-minded man; she has been married for three years and has no children. When persuaded by her husband over the phone while the man is right in front of her, her expression stiffens and her voice trembles—but her pussy is already soaked. Once mounted by the man, she begins grinding her hips and surrenders her body. During the second round, all rationality vanishes as she unabashedly moans, writhing and convulsing in ecstasy. Her inner conflict and emotional turmoil throughout this process are depicted in profound detail.
