The father-in-law wanted a grandchild so he secretly fucked his daughter-in-law

About a year after getting married, I decided to live with my father-in-law. It seemed like the father-in-law was looking forward to meeting our grandchildren. However, she did not have any children with her husband, and their marital life gradually decreased. My father-in-law, who had been watching us the whole time, suddenly attacked us. Every day there is a barbaric meat stick that is incomparable to her husband. And that love continued for a year, two years, four years and then he began to let go of his heart, something he refused to accept.
