Satomi, who became frustrated after living with her husband's father (father-in-law) and had no night life, had an affair with her boss at her part-time job. Her father-in-law finds out about this and gets angry and demands his body. Although she refused, Satomi, who is in her prime, is at the mercy of the forceful caress and ends up being ejaculated. Since that day, my father-in-law, who has an unparalleled sexual desire, does whatever he wants to his wife Satomi, who has big breasts and a voluptuous body, regardless of where he looks.
