Isis Moone steps in as the sister who can't resist the temptation of her stepbrother's massive cock. She teases him mercilessly, denying him release even as she brings him to the brink. With skilled fingers and slippery oil, she massages his prostate, making him beg for release. Twice he cums, once into her waiting hands and again, using his own thick load as lubricant, as she brings him to a second, ruined orgasm.
