Mistress Lea's walking on the riverside wearing white ballet flats. Of course they're quite muddy soon and she commands her slave to get on his knees and lick them clean! The slave is clearly disgusted by this task and begs her not to force him - but Lea doesn't like her slave's talking back and shoves her dirty shoes deep into his mouth. He has no chance but to lick the filthy shoes until they're completely white again!
The sisters took their slave into the woods and their shoes get all muddy after a rainy week. They force him to lie down next to a wooden fence, step on his body and make him clean their muddy shoe soles! He has to lick all the dirt from their shoe soles while they trample his body relentlessly!
