Slave Has To Slurp Boots And Gets Trampled

I notice my office boots are fairly dirty and I want the slave to clean them - but I will make it a little tighter for him! I step on his naked chest and then order him to eat the dirty shoe feet while I trample him. Of course, with me standing on him the entire time he needs longer to clean the boots than usual. When theyre ultimately clean I take them off and proceed to trample him under my sweaty socks - and of course he gets to sniff them as well. When he whines too much I take off my socks as well, stuff them into his mouth and trample him with my naked feet for a while!
