Mistress Natalia stepped on oil and she used it to humiliate her slave. She went indoors and made her slave lick the oil off her feet. She did not care how he would do it. She just wanted it done and he had to do it. She also forced him to lick the floor clean since she had stepped on it and left some marks. The poor slave licked her feet for hours before she allowed him to wash her feet using hot water and soap.
