Boot Licker’s Arms Trampled Under Riding Boots

My railing boots are truly dirty - and I know this slave thinks gobbling dirty boots is enormously repugnant. 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 begin to trample his palms under the hard feet of my railing boots. Then I order him to embark 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.
