The problems of declining birth rate and ageing population were raised decades ago. The bigwigs claimed that they wanted to solve the problem seriously, for example, by setting up a Ministry of the Interior! But there is no sign that the problem has been solved, and time just goes by. I, known as "Uncle Artificial Insemination", want to solve this problem. It's very simple. I just have to ejaculate into a young, cute girl. All I had to do was to ejaculate deep inside her vagina. Why can't people understand such a simple thing? Shouldn't they be held responsible later? Of course, I'm not going to take the blame. I recently met Nana Jam. She's an angel with a sweet smile who always puts up with the giggles of a middle-aged man like me. But I had to get her pregnant without mercy. We took a bath together and cleaned each other. Afterwards, I used a peeper to examine the state of her vagina, the place where I was about to ejaculate. The color was beautiful and it looked great. She was shy because she had never been looked at in such depth before, but she looked so cute that it made me horny. After relaxing her with the toy, I made the final preparations. She was a bit reserved, but the way she carefully licked her way down to the root was a real turn-on. I've actually done bad things with Nayanamari many times, and she always acts so innocent. She's such a good girl. When I penetrated her deeply from behind, she even let out a moan that I've only heard in adult comics: "Oh!" Since she felt so good, there was no harm in cumming deep inside her, so I recklessly released a huge load of semen deep inside her. But the insemination mania didn't stop there. I was determined from the start to ejaculate inside her multiple times, so I went outside to the bathhouse ...... I've already made an appointment to see her again next month, but I don't know how her stomach will feel by then.
