My big amazing ass smothers your face. Blocks your breathing. You try and gasp for air but my ass still on your face you are to smell in. I give you a moment to admire my ass, thank me and beg for me to smother you face again. You got it, I press you nose right by my asshole and "accidentally" let a BIG and STINKY fart go. With the lack of air you have no choice and are to inhale my stinky farts.
