Sis wakes up to find her brother's throbbing erection poking against her back. He insists she rides him hard, taking every inch of him. She hesitates but as he grabs her by the hair and yanks her head back, she knows there's no escaping. She mounts him slowly, moaning as his girth stretches her pussy. He grabs her hips and starts thrusting up into her, their skin slapping together in lustful syncopation. Their hands grip each other desperately as they move together in a primal dance of lust.
