Shit Licked off Dirty Rubber Boots With the Tongue

Elegant and sublime, the mistress sits enthroned in front of the slave. Her elegant, precious outfit and her condescending movements show the slave his place.
He kneels before her feet wrapped in silk stockings and is allowed to hand her the rubber boots. What these are needed for seems unclear, but anyone who knows Miss Yara a little better can guess.
First she has the shiny rubber licked before she places a considerable pile on the floor in front of the slave's eyes.
Slowly and disgusted, she steps into the shit with the tip of her boot. The shoe gets dirty, of course, which the slave has to clean up. She laughs at him and steps in the shit again. The slave has to lick the boots clean again.
Soon she is stomping around in her poo, which the slave watches with a horrified look. His task is clear. The shoes must shine again.
