This femdom has just gotten a new slave and he was under the impression that he would only be licking her clean boots, but that has suddenly changed today. She had to go out to her horses to make sure they were okay. In the process, she walked all over their and lots of mud on the way. Once she gets back, it's time for her slave to go to work.
Mistress Maeva forces a slave to worship her muddy riding boots in the outdoors. He has to eat the mud from her shoes and gets his whole face covered with mud as she pushes the boots hard into his face. To clean his face she spits into his face afterwards - isn't she a gracious mistress?
