A good submissive will always make himself useful in whichever way his Mistress pleases. I've just returned from a sweaty workout and can't think of a better way to use my devoted plaything than to turn him into a human seat. I park my perfect ass in my soft, sweaty leggings right on his face until he is gasping for air. Toying with him is always my favourite part—will I allow him to breathe or will he suffer his fate under my ass?
