Foot Gagging And Licking

I order the slave to come over to me on all fours and then slurp my feet while I loosen on the couch - but hes just too slow! I order him to lie down on the ground, get up and grope 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!
