Roxie Sinner and Kai Jaxon, step-siblings with a naughty streak, find themselves alone on Christmas Eve. Roxie, dressed in a sexy Santa outfit, teases Kai with her jingling bells. Kai, unable to resist, whips out his hard cock, and Roxie mounts him in a cowgirl ride, her tight pussy sliding down his shaft. In a POV shot, Kai watches Roxie's tits bounce as she grinds against him, their taboo family affair heating up under the mistletoe.
