Sachiko, in her prime, was living happily with her beloved husband. However, recently, her older husband had been experiencing erectile dysfunction, leaving Sachiko unsatisfied. Just then, her husband's younger brother, who had been laid off, came to Tokyo to look for a job and ended up staying with them temporarily. The younger brother's job hunting wasn't going well, so the three of them drank alcohol to cheer him up. Soon after, Sachiko and her brother-in-law took her drunk husband to the bedroom. Then, her brother-in-law embraced Sachiko and kissed her. The next morning, her husband, who had no memory of being drunk, saw Sachiko and her brother-in-law with slightly awkward expressions. That night, while her husband was taking a bath, Sachiko was hugged and kissed by her brother-in-law again. She tried to resist, but when she felt his hardened crotch pressed against her, Sachiko became confused and ended up doing as he said, taking his hardened crotch into her mouth.
