Husband infertile, daughter-in-law asks father-in-law to "give" her a child

After her mother-in-law passed away, Kana and her husband decided to live with her father to take care of him. The three of them lived together very happily. However, despite having frequent intimacy, Kana and her husband still did not have children. Kana shared this with her father-in-law, but he also did not know the answer. However, she knew one thing, that her father's sperm was very healthy, which is why her husband had many siblings. Because they did not have children, the couple often had conflicts. Kana decided to ask her father for his sperm to quickly get pregnant, so that everyone could reconcile and live happily together. Because Kana knelt down to beg, her father-in-law could not bear to refuse.

At first, Kana only wanted him to impregnate her, she wore all her clothes and covered her body so he would not see. But his strong and large penis, along with deep thrusts into her womb, made Kana gradually become aroused. She became more open, more proactive, making love with her father-in-law like a truly loving couple. They both promised to end this relationship once she became pregnant. However, after Kana gave birth, they could not resist anymore, continued to engage in sexual activities, and her father-in-law impregnated her once again. And so, in a short period of time, Kana became pregnant again and gave her husband another "child"...
