Rieko had lived happily with her husband since their youth, but recently grew increasingly dissatisfied as her older husband's health declined. Around that time, her brother-in-law, having lost his job, came to the city to search for work and began staying at Rieko's home. Struggling with his job hunt and feeling down, he joined Rieko and her husband for drinks one evening. As the night progressed and her husband became heavily intoxicated, he was taken to the bedroom. Suddenly, the brother-in-law kissed Rieko, creating intense tension between them. The next morning, with no memory of the incident, her husband remained oblivious, while Rieko and her brother-in-law exchanged awkward glances. That night, while her husband was in the bath, the brother-in-law approached Rieko again and kissed her. Though she resisted at first, when she touched his hardened erection, she hesitated, then gave in—eventually taking him into her mouth as he whispered to her.
