Mistress Nica was not comfortable with how forgetful her slave was. She had to do something about it and she did. She used her boots to trample him and make him regret being forgetful. He did not expect such a punishment from him and that is what made him get even more scared and what made the punishment be even more effective. She had a great time and she got him to do something about his forgetfulness too.
Mistress Nica loves to use her dirty feet as well as her dirty boots to dominate. Today she made sure her feet were dirty deliberately and she used them to dominate and to humiliate. The mistress sat on a pallet and she watched her slave lick her dirty boots, her dirty socks, and her dirty feet as she enjoyed and instructed him on what to do to the things he was licking.
