Slave Coerced To Lick 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 soles are completely covered with all kinds of dirt - 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 dirt from the boot soles with his tongue and swallow all of the disgusting 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!
