With her submissive in the perfect position, the mistress commands him to stay still, her voice dripping with authority. She leans in, her tongue tracing circles around his asshole, making him squirm with pleasure. She takes her time, worshipping his body, her fingers tracing patterns on his skin. When she finally slides her strapon inside him, he gasps, feeling every inch of her. She fucks him hard, her heels digging into the floor, her body slapping against his, leaving him a panting, spent mess, ready for her final command - to clean her heels with his tongue.
