This mistress did not want to be bothered. But this guy did not get that and he bothered her. She had to teach him a lesson and she did it by farting on him. The mistress ensured that the guy would never do that again by nearly choking him with her farts. He had not expected that she would do so and it was a shock to him. He begged her not to do it again and she told him not to bother her.
This mistress had an issue with her slave and according to her assessment of the situation, she felt that the best way to go about the issue was to turn her slave into a fart slave. So she made sure that she got the slave to lick as well as smell her ass and in so doing, lick and smell her farts too. And it was so humiliating the slave changed instantly.
