Slave Coerced To Slurp The Street Dirt From My Boots

I just love these comfy boots - and I wear them all the time. But that also means they get pretty dirty quickly - the feet are entirely covered with all kinds of mud - who knows what I stepped into! I walked with them on the streets, in shops, maybe even in a public toilet? But thats not going to be my problem! I call for the slave and order him to clean off all the mess from the boot feet with his tongue and guzzle all of the abhorrent dirt. And when hes done with the boot soles, hell polish the leather of the boots with his tongue as well until its nice and shiny again!
