After This, I'm Going To Get My Brains Fucked Out By My Father-In-Law And His Orgasmic Cock Until My Husband Comes Home... Minami Kojima

Around the third year of marriage, the mother-in-law passed away, and at her husband's request to look after the worried father-in-law, she began living with him. From then on, she always felt like someone was watching her... or her underwear would go missing—an unsettling life began. Then one day, she was forcibly raped by the father-in-law, who should have been aging... and she learned the truth about his abnormal sexual desires. From that day on, whenever her husband was away, she was forced to serve her insatiable father-in-law.
