Madame Marissa - Slave licks our muddy riding boots in the woods

I'm going for a walk in the woods with my friend - and the slave follows us on all fours a few meters behind. It rained quite a lot in the last few days and our riding boots get really dirty. Time to put the loser following us to some use! We sit down on a fallen tree and order him to lick the mud from our boots. To humiliate him even more we take turns spitting on each other's boots and make him lick the dirt-spit mix. When he finally licked all 4 boots we push him to the ground, walk over him and continue our walk. Obviously he'll have to clean our boots again when we get back home!
