Plod is one of Mistress Vivienne’s house slaves. As a collared slave he signed a contract giving Mistress the right to punish him for transgressions as she thinks fit. “Plod come here - you’ve been lying to me and sneaking out to eat junk food. That’s why you’ve got this belly on you. You’ve been eating McD’s for breakfast”. Mistress Vivienne wacks his ass with a leather strap. Since he eats things Mistress doesn’t like him to eat - his punishment will be to eat things he doesn’t like to eat - its jizz for breakfast.
