Miss Amy and her friend mistress BlackDiamoond were teaching a friend of theirs how to humiliate and punish a slave. They made the slave lick their soles before they trampled him using their high heels. He had undressed and was naked before they trampled him. That meant that he felt a lot of pain. But not even his cries of pain did anything to stop the mistresses from showing their friend how to torture a slave practically.
