Lady Tassia felt that her slave was careless. He did not know where he put things, he forgot some of the chores he was given and he did not take his job seriously. Sometimes he broke up things and wasted others. So she made him stop all of those things by slapping the crap out of him. The mistress also had him eat food from the ground before she was done with him.
Princess Serena has her slave in between her legs but not in the way that he wants to be. She has her feet on his head and she's about to show him his place. She makes sure to grind in with her hard soles before moving to get her hands in on the action. She gives his face a few slaps and takes off her shoes. Then she slaps him with her naked feet, leaving the smell of her sweat on his cheeks.
