39-year-old Yukari Fujisaki. Her husband is 42, and they've been married for nine years. They have no children due to her husband's fertility issues, yet they still feel happy together. However, her husband carries some guilt, worrying that he isn't sexually satisfying his wife. To resolve this, he arranges for another man to take her. After their first encounter, the man suddenly ambushes her in the shower room. They kiss in the changing area, then she gives him a blowjob. Next, he torments her with a vibrator and hands it to her. She experiences pleasure from its vibration and penetration, which excites him further as he watches—prompting him to begin vibrating her himself. Fully aroused, the man takes her back to bed for more.
