Yuka Matsushima is a beautiful, warm, domestic caregiver who even cleans the father's penis during his care, leaving him slightly erect. After watching the entire scene, the jealous son begins flirting with her. He offers a massage to thank her for caring for his father, then lets his hands wander somewhere far more intimate. Yuka gradually gives herself over to the caresses and fills the room with moans, while the father remains nearby.
