After a period of time in the city, Koji decided to return to the countryside. He was told by his older brother about how he and his sister-in-law had been trying hard but still couldn't conceive. Koji didn't pay much attention to it, but by chance he witnessed the intimate scene between the two. It seemed like Jun also saw him, but she wasn't shocked or embarrassed, instead she actively displayed her body for him to admire, showcasing all her skills for him to see. From that moment on, Koji couldn't take his eyes off his incredibly attractive sister-in-law. Jun truly wanted to have a child, so she secretly took her husband's sperm for testing, and the result showed that his sperm wasn't healthy enough for conception. Knowing that no matter how many times she had intercourse with her husband, it wouldn't lead to pregnancy, on the day of ovulation, she begged Koji to provide his sperm, ejaculate it into her, and make her pregnant. Despite knowing that this act was extremely wrong and disrespectful to his older brother, Koji couldn't resist the incredibly beautiful sister-in-law of his!
