After her mother-in-law died, Kana and her husband decided to live with their father to take care of him. The three of them lived together extremely happily. The only thing is, although they have sex with each other often, Kana and her husband still have no children. Kana shared this with her father-in-law, but he didn't know the answer. But she knows one thing, that is that her father's sperm is very healthy, which is why her husband has a lot of brothers and sisters. Because they have no children, the two often have disagreements. Kana decided to ask for her father's sperm so that she could get pregnant quickly, and everyone would live together happily again. Because Kana knelt down and begged, her father-in-law was also reluctant to refuse. At first, Kana only wanted him to conceive for her, so she wore her clothes and covered her body so that he wouldn't see her. But the big and strong cock along with the strong blows deep into the uterus made Kana gradually become numb. She gradually became more open, more proactive, making love to her father-in-law like a real loving couple. Both promised to end the relationship when she got pregnant. But after Kana gave birth, the two could no longer bear it, continued to throw themselves into each other, and her father-in-law impregnated her once again. And just like that, in a short period, Kana became pregnant again and gave her husband another "child"...
