Lady Shay loves to dominate guys but for what she wanted to do to this loser, she felt it was only appropriate to compensate him for what he did. And that is why she chose to pay him to smell her farts. She was all gassy and ready for the farting session. His work was to stick his nose in her ass and when he was done smelling her ass and farts, lick her butt.
Lady Shay wanted to punish her slave but she did not want to use any pain to do it. So she chose to do it the easiest way she could which was to use farts to do it. The mistress was gassy and it was easy for her to do it. And to make sure it was worth her while, she made him smell them by being in close proximity to her ass.
Lady Shay wanted to turn off this guy. He was into her and she did not want him to bother her anymore. So she invited him to her house. She put on a show for him and he loved it. But in the middle of it, she farted. It was a stinky fart and she did not do it once. She did it severally and he was turned off and stopped bothering her.
