It's a gassy night at Mistress Kasia's house, what better time to start training her slave to become aroused by her ass. She taunts and torments him with her gas while demanding he rub his clit to the smells of her asshole. She orders his tongue deeper and deeper inside as she farts right in his face; she berates him over his hardened clit and reminds him that he's not allowed to cum.
