Foot Gagging And Gobbling

I order the slave to come over to me on all fours and then munch my feet while I relieve on the couch - but hes just too slow! I order him to lie down on the ground, get up and touch my sweaty foot feet over his tongue - now thats a way more effective cleaning! And in this position, I can shove my feet into his mouth as well, coercing him to suck my toes clean!
