"Big brother, you're a virgin and know nothing about girls, right? I bet you've never even seen a girl's private parts, lol. Virgin loser cock, virgin loser cock, hehehe."
The brother's patience finally snapped. He showed off the huge cock he had been hiding, but...
"Huh, so that's what it looks like! My friends say I'm great at sex, but you'll probably just cum and be done in a second."
Such an incredibly sassy brat sister. Her body grew up, but her attitude didn't. Since it looked like it would fit, he shoved it in all the way.
"Raw pussy feels so good, ah, I'm cumming, I came so fast..."
But it was okay. Without pulling out, he kept pounding her. Even after creampie after creampie, he didn't stop thrusting. Wait, looking at his sister's face, she's feeling it.
"There's no way I'd cum from this..."
Her beautiful bowl-shaped breasts jiggled wildly as she moaned vulgarly, losing herself in pleasure. If he keeps creampieing this incestuous pussy until the sperm flows back out, she might actually get pregnant. The sense of immorality only accelerated his thrusting.
"I'm sorry, I'm sorry! I was the loser pussy! I'm cumming!!!"
Total submission achieved. Now both my heart and my cock feel refreshed and satisfied.
