Madame Marissa wanted to dominate this guy and she was not going to let anything get in the way of her doing that. That is why she forced him to lick her feet and especially her smelly socks. In addition, the mistress ensured that the slave was in a lot of pain as she stomped on him. She also had her high heels which he licked. He was lucky she did not ballbust him with the heels.
