Lick the dust from under my socks!

Mistress Morana: Lick the dust from under my socks!
In my free time I like to walk around the apartment and office in my socks, or even outside on the balcony. Today I’m wearing my dusty socks in my sneakers. The socks look clean from above, but the soles of my socks are dusty and a little dirty from the dirt from the floor.
The slave always has to lie at my feet and after he takes off my sneakers, he can remove the dust from under my socks. I want to use his tongue and stick my socked feet deep in his mouth. He is welcome to eat and swallow the mess from my socks. That’s a great slave meal: sock dirt from the mistress.
