A stepdaughter, Natalie Brooks, has developed a bad habit of swearing. After the latest incident, her stepmom, Pristine Edge, is completely fed up and 'punishes' Natalie by facesitting on her to put her tongue to better use! But this seems to backfire since Natalie uses lots of FILTHY dirty talk during the raunchy session... and Pristine gets so turned on by it that she starts dirty talking too!
