Decades have passed since the issue of a declining birthrate and aging population was first raised. The bigwigs say they'll tackle the issue seriously, like establishing a Home Affairs Agency! But the problem shows no signs of being resolved, and time just keeps passing by. I, the "Inseminating Uncle," will solve this problem. It's simple. Just cum inside a young, cute girl. Just cum deep inside her pussy. Why can't people understand something so simple? Shouldn't they just figure out responsibility later? Of course, I have no intention of taking responsibility. I recently met Nana-chan. She's an angel with a lovely smile and always puts up with this middle-aged man's silly jokes. Well, I'm going to inseminate her mercilessly, though. We shower together and wash each other. Afterwards, I use a speculum to carefully examine the state of her pussy, the place I'm about to cum inside. It's a nice color, and it looks amazing. She's embarrassed because she's never been seen deep inside, and it's so cute, it makes me want to cum. After using a toy to loosen her up, I make the final preparations before insertion. She's a little awkward, but I'm excited by the way she carefully licks from the base. I've actually done naughty things with Nana-chan many times, and she always responds with such innocent grace. She's truly a good girl. When I thrust deep into her from behind, she even lets out a moan I've only heard in erotic manga, "Oh!" If she's feeling that good, it's fine to cum deep inside her, so I irresponsibly release a huge load deep inside her. But this insemination man doesn't stop there. I was determined to cum inside her multiple times from the start, so I went to the outside bath... I've made an arrangement to meet again next month, but I wonder how her stomach will feel.
