Housekeeper Yui is assigned to the home of a lonely middle-aged man who lost his wife and child. While cleaning, she becomes engrossed in a porn magazine and indulges in masturbation. Caught by her employer, she struggles but cannot resist as he forcefully creampie her, filling her womb with his sperm. Her wet pussy throbs intensely, and she repeatedly squirts large amounts under the stimulation of fingering and vibrator. Moaning in ecstasy, she begs for his cock, growing even more aroused by the thick cum shooting deep inside her uterus. The film captures Yui's raw, intimate sexual experiences.
