Mistresses Cybill Troy and Elena De Luca want their slave to know that he is just a piece of livestock to them, something to be branded and owned. As the Mistresses cane his ass until it is a deeply bruised and marked purple, they remind him that they own his entire body and will do whatever they want with it. They will mark his ass so that the entire world will know that he is nothing but the chattel of his Mistresses.
