Mistress BlackDiamoond knows how to punish a slave. There is hardly any mistress who can match her skills. Today she was tutoring her friend how to do it. She made him tie her slave to a post and they slapped the crap out of him. That was not all. They had him naked and they ballbusted him as well. It was not just painful, but it was sadism at its best.
Mistress Melisa does not like to have weaklings near her. She realized that her new slave was a loser. She wanted to change that so she humiliated him and beat him up to change it. It was hard at first but the more she did it especially slapping the crap out of him helped him to change slowly. When she was done, he had become a macho guy and even he could not believe it.
