Mistresses Maya, Britney, Bea and Teodora were training themselves to humiliate slaves and losers. They do not like to have someone else train them. They prefer to do it themselves. They got themselves a slave and enjoyed humiliating him. They crushed his throat and other parts of his body and judged themselves on areas they needed to improve on. The feedback was instantaneous and they tried all sorts of things on him making it even more painful.
