BBW Lady Cathy wants to see how far her slave goes for her. So she eats a Twix in front of you, chews a while and spits it out on the ground. Don't think she's done yet - she smiles, and grinds her sole over the chocolate until everything is a smashed muddy mass. She lifts her shoe and hold it directly in your face to make you eat and lick it up for her. The ultimate slave proof.
