ADN-522 Is the child in my stomach my husband's or my father-in-law's? Saya Endo, the father-in-law who kept raping her son's wife

Five years ago, my wife died in a traffic accident. Since then, I've been living like an empty shell. The only thing her heart could rely on was the presence of her son. Her son introduced her to me, saying he was getting married. It was her wife. Her wife was there. When I saw Saya-san, I couldn't suppress the sexual desire that rose up for the first time in five years.
