Sometimes, for good work, my Mistresses give me power over other slaves. I know that Iren used to be a Mistress but now she is below me in status.. I decided to order her to sniff my socks.. I can see how humiliating it is for her to worship me but I dont care.. I like that she feels even more humiliated now . After which she licks my bare feet while I rest.. it's great to be a Mistress...Marina..
