Lick The Mud Out Of My Boot Tread

There was a lot of rain lately - and the ground is terribly muddy everywhere. Well, fortunately thats not my problem - I just walk through the mud and then order a slave to take care of my muddy boots :-D These boots have a indeed deep tread and therefore collect even more mud than my other footwear - so the slave will have a lot of dirt to swallow now! I order him to start licking the soles and make sure he gets his tongue into every groove of the tread. Its so funny to see his tongue getting completely brownblack after only a few licks! And of course, he wont be allowed to stop until both boots are completely clean again!
