My Mistress Sarah is often not happy with me .. I try to please her but it doesn't always work out. And sometimes she just wants to humiliate me and orders me to worship her dirty feet. Of course, I lick all the dirt, but when her feet are clean, she goes to dirty them again. This is how she punishes me for my misdeeds .. Or maybe she is having so much fun .. because she likes to humiliate me. But I will do whatever she tells me .. she can dirty her feet indefinitely and I will still keep them clean. When she got tired of it, she ordered her to put on her sandals and clean them. I licked her sandals and she went for a walk, ordering me to sit and wait for her return. ..Christina..
