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

Haruka is blessed with a kind husband and has a happy married life. However, there was one thing that Fuka had to complain about, living with her vulgar stepfather. 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 Haruka, he makes the most of his son's absence and plays with his young body and rapes Haruka. From that day onwards, my father-in-law found an opening and would always violate his beautiful wife...
