This mistress had paid for gym membership but her gym instructor was shitty. She did not like how he trained her. He was always looking at her boobs and her ass and did not concentrate on his job. So she plotted to punish him and she did it humiliatingly. She forced him to lie down and she crushed his face with her ass. He had to lick and smell her ass before she let him go. She farted to make it more humiliating.
Mistress Gaia wanted to make sure that her slave would be obedient for good. She did not want to have to punish him every other time. So she punished him once and made sure it was good even for the future. She facesat on him and nearly choked him. She made him smell her ass and lick it as well. She stroked his dick in a rough manner to make him feel pain too.
