Mistress Zephy had a score to settle with this guy and when she thought about it, she felt that converse femdom was the best way to do it. She did not think twice about it. She crushed him with her converse sneakers and made him lick them clean. The soles were dirty but she did not care. He had to lick them as it was a command and not a request.
Madame Marissa was surprised that her friend had never tried slave humiliation. So she invited her to her house and the two mistresses who were both wearing converse sneakers used them to trample madame Marissa's slave at the same time. It was cruel and painful but they were having fun so they did not care about how he felt. His cries of pain fell on deaf ears as they went on trampling him.
