FNS-088 Until just now I thought my sister was just a brat, but she started seducing me with her panties, so I fucked her over and over again while my parents weren't home... Yayoi Hamabe FNS-088

It's been a long time since I've been back to my hometown. My younger sister, Yayoi, and I were very close when we were little, but we started to drift apart when I went through puberty. Seeing her again after so long, she looked unusually mature for some reason. But has she not fully matured yet? Her underwear is always showing… no, is she showing it on purpose…? That piece of fabric clinging to her crotch doesn't completely cover her big butt. I won't get aroused just because she's my sister… And so, my parents went on a trip. Even with just the two of us at home, the act of showing her underwear wouldn't stop. My lust for my sister also wouldn't stop. Once I reached out, it was endless, and while my parents weren't home, we had sex. My sister should be this cute… she should be this erotic… Even though I thought that, I continued.
