Princess Karlie has just recently learned how much fun it can be to whip a man. As her skills mature, so does her desire to whip harder and harder. This is her hardest whipping clip to date, though there will surely be more to come. She slashes and thrashes Bart's ass and back with a permanent grin on her gorgeous face. As the stripes begin to materialize, so does the speed of Karlie's whip. At the end she whips his cock and slaps the hell out of his nuts.
