Boot Licker’s Arms Trampled Under Riding Boots

My railing boots are truly dirty - and I know this slave thinks slurping dirty boots is utterly hideous. But of course Ive my ways to ensure the job gets done anyway. I order him to put his mitts on the ground and then start to trample his hands under the hard soles of my riding boots. Then I order him to start cleaning the boots with his tongue - while I still stand on his hands. Of course, the slave now knows the pain is going to be much more intense if he doesnt do his job properly and starts to lick away all the dirt! But the sadist in me cant help it - Ive to trample his hands some more even if he does a good tongue-cleaning :-D.
