Lady Shay felt like her slave was due for some punishment and she settled on using her fart fetish to do it. Her big ass was best suited for it so she tied him up in a chair and went to where he was and she made him smell her farts. They were stinky and lingered for a long time. He could not do anything about it and he learned not to piss her off.
Lady Shay wanted to try fart fetish and she did not have anyone else to do it with so she turned her slave into her fart smeller. The mistress did not even do it as a punishment. She just did it because she felt like. He had no choice or say in the matter and he knew it. So he did not bother asking her why she was doing that to him.
