Mistress Valentina is a gorgeous girl and she knows it. She has many admirers and this one tried to hit on her today but she did not let him go far. He was nowhere her league and she did not want to encourage him when he did not have a chance. So she instead of that, she farted on him and she had him not only lick her ass, but also smell her farts.
When mistress Valentina was pissed by this guy, she knew that it was time for her to react and to get even. She was doing this so that the guy would not think that it was ok to mess with her and think that he could get away with it. So the mistress used her farts to choke him and she did it in a way that he was humiliated as he also had to lick her ass.
