The brother, an eager amador, can't resist his sister's provocative moves. She's a putinha, a slut, but she's his, and he's going to claim her ass. He spreads her cheeks, revealing her puckered hole, and spits on it, lubing her up. She gasps, pushing back, wanting more. He obliges, slamming into her, his balls slapping against her pussy. She's a mess of moans and cries, her body shaking as he fucks her raw, leaving her ass red and used. But she loves it, she's his dirty little sister, and she'll take it all.
