Mistress BlackDiamoond was teaching this mistress how to torture and humiliate slaves. She wanted to learn practicals as they had done a lot of theory. So mistress BlackDiamoond came with a slave and they had a great time humiliating him. The student was a natural and she pissed on the slave and spat into his mouth and did things which she had not even been taught by mistress BlackDiamoond. She was impressed with her student.
Mistress BlackDiamoond and her friends lady Chanel, mistress Amy and lady Xena found out the guy who was the source of their trouble. He had to pay for his sins and he paid for them dearly. The mistresses had no hurry as they punished him. They did it slowly for maximum impact. The mistresses forced him to lick their boots, they used him as a human ashtray and all manner of nasty punishments. They made him make amends for what he had done.
Mistress BlackDiamoond and her friend did not like the fact that this guy was seducing them both at the same time. He thought they did not know each other so his secret was safe. But they knew each other and his secret was not safe. They punished him together and they did it brutally. He had to learn to stick to one girl and they made sure he did learn that.
