It was good that my father-in-law, who seemed to have suddenly quarreled with his wife, came over and stayed for a few days, but it turned out that he found out that Manami was sexually frustrated. So, pretending to be his wife, he approached Manami, and the sexually frustrated Manami also enjoyed pretending to be his mother-in-law. She realized halfway that it was my father-in-law's strategy, but she couldn't go back and was filled with semen in her vagina. From then on, she was lured into my father-in-law's demands and her body was ravaged.
