You're smelling Mei, your girlfriend's ass through her thong and fishnets, she doesn't know you have a fart fetish and can only dream of her delicious and strong flatulences to wrap you... her stomach rumbles and she farts on you, she is embarrassed and repeatedly tells you she's sorry... but she realizes your face doesn't mean disgust, the complete opposite. She is turned on and starts doing different postures to push the farts out on your face. She tells you to masturbate with your face in her ass, asking you to cum when she counts down to zero, where she starts doing the loudest farts. This was very dirty and sensual, and has strenghtened your bond and relationship
