Caught off guard by his sister's unexpected return, a Brazilian brother finds himself face-to-face with her lush body. She, too, is caught in the moment, her eyes locked on his growing bulge. They freeze, then surrender to their lust, stripping each other with urgent fingers. He groans as she takes him in her mouth, her wet, eager sucking driving him wild. She straddles him, impaling herself on his rock-hard cock, riding him with abandon until they both collapse in a sweaty, satisfied heap.
