His Slave Tongue Cleans My Dirty Boots

My dirty boots are just the thing for my slave. He will now slurp them accurately clean until I am pleased with them. I require him to gobble off the filth and guzzle it down. His black tongue already looks fairly disgusting and shows me how thoroughly he does his job. But if you get dirt on your tongue, you spread it all over A little of my precious saliva will certainly solve the problem! I spit on my boot and this time I make him lick off the dirt together with my saliva. Thats much better now, isnt it?
