After her mother-in-law passed away, Kana and her husband decided to live with her father-in-law to take care of him. The three of them lived happily together. However, despite having frequent sexual intercourse, Kana and her husband still hadn't conceived a child. Kana shared this with her father-in-law, but he didn't have an answer either. What she knew was that her father-in-law had very healthy sperm, which was why her husband had many siblings. Due to the lack of children, the couple often had conflicts. Kana decided to ask for her father-in-law's sperm in order to quickly get pregnant, so that everyone could reconcile and live happily together. Because Kana knelt down to beg, her father-in-law couldn't bear to refuse. Initially, Kana just wanted him to impregnate her, so she wore all her clothes and covered her body so he couldn't see. But his large and strong penis, along with the deep thrusts into her womb, made Kana gradually feel intoxicated. She became more open, more proactive, making love with her father-in-law like a truly loving couple. They promised to end this relationship once she became pregnant. However, after Kana gave birth, they couldn't resist each other, continuing to engage in sexual activities and her father-in-law impregnated her again. And so, in a short period of time, Kana was pregnant again and gave her husband another "child"...
