Step-mommy is farting

I wake up early in the morning with VERY bad gas, and go and sit on the couch in the living room. I start ripping deep looong bubbly farts into the seat cushion. My step-son is still in bed jerking off to the sounds and I’m calling him to get up for studies, angry at him for not getting up yet. Eventually, he gets up. While he’s in the bathroom getting ready I continue to belt deep melodic gulpy farts into the couch cushion. Today is an especially gassy day for me, and I even impress myself with the tones I m achieving. I am trying to hold back a bit because I don’t want to turn him on too much as he must get to his studies. It’s to the point where I wish he could stay home to experience it but he’s run out of sick days and must attend studies.
