Mistress BlackDiamoond tied her slave to a cross and she called her students to come and try what she had taught them on him. They had lots of fun humiliating, degrading and torturing the slave. They did all she had told them including slapping and kicking the slave. It was brutal but the slave knew he could not cry or else they would increase his punishment. So he braved the torture he got.
There is nothing this mistress enjoys more than humiliating others. While other people go out to do what they need to do, she goes out to look for guys to humiliate. And she found one. She went back home with him and she made him lick the dirty soles of her boots before using the same boots to trample him and humiliate him. She had lots of fun while the guy she humiliated was degraded.
