Slave's licking disgusting soles of My boots, then I’m using his pathetic face as a footstool

Description: I was on a date and my shoes are dirty after it. i emphasize that fact every time, cuz i really love cuckold. my pleasure when my slave realizes that he's nothing more for me than a slave. he's just a nonentity which deserves only pain and humiliations for my pleasure. i love to remind him that the highest closeness to me allowed him is licking dirt from my shoes. there's something really disgusting on the both of my heels. that's two black sticky spots, fuel oil or something similar. i don't know what exactly it is but it should be licked and swallowed. actually this bitch said me that he had a stomachache next day after he swallow most of that mess from my boots, lol. after he's done with the soles, i order him to lay down under my feet and i'm using his pathetic ugly face as a soft footstool, and wiping on it the dirt remains as well..
