My stepfather I hate is being raped at night...

Aoi is blessed with a kind husband and has a happy married life. However, Aoi had one dissatisfaction: living with her vulgar father-in-law. She doesn't want to be alone with her father-in-law during the day when her husband isn't around, so she goes to work, but due to her busy work, she ends up getting tired and falls asleep at home where only her father-in-law is. When the father-in-law finds the defenseless Aoi, he makes the most of his son's absence and plays with his young body, playing with Aoi and rapes him. From that day onwards, whenever my father-in-law was alone, he would always enjoy the beautiful body of his beautiful wife...
