My mother-in-law passed away three months ago, since then my father-in-law has fallen into gambling and alcohol. My husband doesn't want his father to continue like this, so he wants to bring him to Tokyo with us, and I agreed with him. But even after coming here, his gambling and drinking habits did not stop. My husband is very kind so he can't say anything to his father, both of them turn a blind eye to his actions. But one day, I witnessed my father-in-law stealing money from the family living expenses, he casually took the money in front of me to go gamble. And he also knows my secret, that my husband can't satisfy me. I have always had to masturbate and my father-in-law saw it. He took the money and forced himself on me, but instead of hating him, I felt pleasure from the conquest he brought. Since then, every time my husband goes to sleep, I go to his room to be his wife, replacing my deceased mother-in-law...
