Awakening to the sensation of soft lips around his morning wood, our unsuspecting stud finds his nerdy step-sister wide awake and eager to please. Her petite frame kneels between his legs, her big ass barely contained in her tiny shorts, as she takes his massive cock deep into her throat, expertly working her tongue along his length. The POV angle captures every slurp and gag as she worships his big dick, her enthusiasm belying her usually studious demeanor.
