A shadow peeks into the bedroom of a couple having sex late at night. Sumire felt happiness every day since marrying her husband. As he grew older and weaker at night, she felt hungry for sex in contrast. During this time, she had to live with her father-in-law. Her father-in-law was kind, and Sumire thought they could live harmoniously, but she was bothered by his gaze sometimes. Then one night, after a long time, they had sex. Her husband finished quickly just from being a little rough, leaving Sumire unsatisfied. Her figure was seen by her father-in-law.
