For decades now, declining birth rates and aging populations have been highlighted as major social issues. Despite numerous initiatives and serious policy efforts, there's still no sign of improvement. Time just keeps passing by. Amid this stagnation, I've decided to take matters into my own hands as a "seed-planting uncle" to solve the problem myself. The truth is, this issue is actually very simple—after all, all you need to do is creampie. If I blast my load deep inside a young, cute girl's pussy, the rest will naturally follow. Why can't people understand something so straightforward? As for responsibility? That's something to think about later. Of course, I have absolutely no intention of taking responsibility. I'm just here to enjoy myself. Recently, I met Nana-chan. Her smile is absolutely gorgeous, and she always patiently indulges even my lame old man jokes—she's like an angel. But even someone as pure as her won't be spared from my seed planting. We take a shower together, washing each other's bodies, and I carefully inspect her pussy with a speculum, preparing to creampie her. Her color is beautiful and her condition is perfect. She blushes shyly, embarrassed that someone is looking so deep inside—such a cute sight that I almost cum right then and there. After loosening her up with a toy, it's time for the final preparation before penetration. She licks me from base to tip with slight awkwardness, but her careful attention has me completely aroused. I've already had sex with Nana many times, yet she still reacts with such innocent surprise every time—it truly moves me. When I take her doggystyle and thrust deep inside, she lets out a moan like "Ohh fu—" a sound you'd only hear in erotic manga. If she feels that good, then filling her deep with creampie is no problem at all. Thinking that, I irresponsibly unload massive amounts deep, deep inside her. But that's not where it ends—that's the true nature of the "seed-planting uncle." I'd already decided from the start to creampie her multiple times. Then, we head to the outdoor bath, making plans to meet again the next day. I'm already looking forward to seeing her next month—but I wonder what condition her belly will be in by then.
