Step-Mommy Farting at Midnight

It's the middle of the night and I wake up with very bad gas. This is an extreme drive of gas I'm having, and I must go sit on the couch in the living room to relieve myself. Whenever I have a gas drive in bed I tend to go into the living room in an effort NOT to wake anyone up in the house. I proceed to sit on the couch in my lsexy nightgown and FULL BACK panties on, and start ripping deep gulpy ones into the cushion. I don't want to wake anyone up in the house, especially my step-son (since I know how much he loves when I'm gassy). So I need to rip them extra slow and long. I can't push them out loudly, so they end up being EXTRA long and musical sounding. I sit there legs crossed and rip some of the longest, bubbliest farts I ever had in my life, trying to get some relief. Since I can't be too loud, the farts keep building up, and they don't stop, one after the other. There's so much gas built up inside of me that the farts tend to last much longer than usual .
