Slave's licking gross soles of My boots, then face as a footstool after cleaning

Description: I love to point that fact every time, that my shoes dirty exactly after date, cuz i love cuckold and i love when my slave realising that simple truth, that he's nothing more to me than a slave, 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 is somthing really disgusting on the both of my heels: some two black sticky spots, fuel oil or something similar, idk what exactly it is, but it should be licked and swallowed, cuz i'm ordering it! (this bitch said me that he had a stomachache and vomit next day after he swallow most of that mess from my boots, lol, might think like i care). after he done with the soles, i'm ordering him to lay down under my feet and i'm using his pathetic ugly face as a soft footstool, and wiping on it the lost dirt as well.
