Due to living with her husband's father (father-in-law), Satomi lost her nightlife and became sexually frustrated. She started an affair with her boss at the part-time job. However, this was found out by her father-in-law, who scolded her and demanded sex. Although she refused, faced with forceful caresses, Satomi in her prime could only submit, ultimately being made to receive his semen inside her. Since that day, her insatiable father-in-law would take advantage of her whenever he saw her, regardless of the place, abusing her voluptuous body with large breasts.
