Mistress Gaia had waited for a long time to punish her slave. He had learned her habits and it helped him minimize problems with her. That helped him stay safe. But today he messed up and the mistress took advantage of it and punished him. She made him lick the soles of her feet as well as her socks. She used him as her human ashtray and also blew smoke on his face.
Mistress Gaia knows what to do when her slave messes. She is one of those mistresses who do not have a template to punishing slaves. It all depends on what a slave does. The crime has to go hand in hand with the punishment. What her slave did today warranted her to make him lick her feet and her shoes, and that is exactly what she made him do besides trampling him a bit.
Mistress Gaia never goes anywhere looking less than perfect. She was not sure of how her shoes looked. They were clean but she thought they needed to be cleaner. So she made her slave lick them again. He had to do it while she wore them. He was kneeling and as he bent over to lick them, she would spank his ass if he did not do it as well as she wanted.
