Here Everything Is Slurped Clean

I hate dirty boots, so my slave will clean them! With his tongue he licks the filth off and guzzles it without any argument! He cleans my dirty boots flawlessly, because that is what I request from him. I dont let a crumb of filth escape him, because I look very cautiously and make the slave take in every little particle of dirt! Under my supervision absolutely nothing is overlooked and everything is licked cleanly!
