This big-assed amateur sister can't keep her hands off her brother's massive cock. She plays with it, teasing it until it's rock hard, then masturbates it aggressively, her tight grip and fast pace driving him wild. He can't help but finger her soaking pussy, her juices dripping down his hand. They explore each other's bodies, their lust insatiable, until they're fucking hard and fast, her big ass slapping against his thighs as he pounds into her. They cum together, their bodies entwined, their taboo love a secret they'll keep until dad's next trip.
