"Onii-chan's a virgin and doesn't know anything about girls, right! See, you've never even seen a girl's important parts, lol. Virgin small dick, virgin small dick, heh heh heh" – Such taunts from his younger sister snapped the older brother's patience. When he showed off his hidden big dick, his sister said, "Huh, so that's how it is! My friends say I'm good at sex, and you'll probably cum right away and be done, onii-chan," acting cheeky like the bratty little sister she was. Her body had grown though, and it looked like he could insert it, so he plunged it in all the way. The raw pussy felt good, ah, he came, it came out right away... But it was still okay, he kept thrusting without pulling out. Even after creampie after creampie, he didn't stop his hip movements. Hey, looking at his sister's face, she was feeling it. While saying, "There's no way I'd cum from this," she shook her beautiful bowl-shaped tits and moaned vulgarly, cumming like crazy. Even after this incestuous creampie until sperm flowed back into her womb, she might even get pregnant. The sense of taboo accelerated his thrusts even more. "I'm sorry, I'm sorry, I was a trash pussy, I'm cummingggg," she surrendered, defeated for sure. With this, both his heart and his dick felt refreshed and good.
