Marinka's slave knows that if he wants her to tolerate even 5 minutes of his pathetic company that he must worship her feet. He submits to smelling and feeding on her sweaty socks while she sits on him and smashes her sock feet hard into his face. He's then force to sniff the vinegar smell of her sweaty bare feet and lick them clean with his slobbery tongue.
The mistress insists upon a clean horse stable, and her silly slave boy has disappointed her yet again. While he's lying on the floor of the dirty stable, she alternates between stepping in horse scat and on this poor loser's chest, trampling him and covering him with horse shit. Her method of discipline is harsh but effective, and he's eventually reined in to be her ultimate submissive slave.
