The sister, her body aching with unquenched desire, takes charge. She straddles her brother, impaling herself on his thick cock. She rides him, her tits bouncing, until she's panting and on the brink. Her brother, unable to hold back, grabs her hips and fucks her hard, his balls slapping against her ass. He grunts, his cock swelling, and fills his sister's pussy with his creamy load, their bodies entwined in a dance of forbidden lust.
