Mistress BlackDiamoond and her friend wanted to show this slave that they meant business. He had swindled them of their hard earned cash and they wanted their money back plus the interest it was supposed to have generated. The mistresses facesat on him after tying him up. They made sure he could not resist whatever they were doing to him before they began doing it. By the time they were done with him he had agreed to give them what they wanted.
