Mistress Polina had a new slave and she needed to punish him. She felt that he was taking a lot for granted and that did not sit well with her. It all had to change and the mistress forced the guy to change. That was done by forcing the guy to smell her stinky socks. The socks were smelly for that purpose and it was effective as he did not want to experience it again.
Maeva has the dirtiest black sneakers anyone has ever seen. but she has a easy foot and sole slave. He willingly licks her converse shoes until they are clean. She is not satisfied so she pulls off her shoes and puts her smelly socks in his face and does a little facetrampling before stuffing her bare toes in his hot mouth.
