It's the middle of the night and I wake up with very bad gas. This is an extreme attack 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 attack 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 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 and eventually become VERY deep and gulpy, even though I'm trying not to wake anyone up. What I DON'T know, however; is that my son heard me farting from the bedroom, anticipated that I would go sit on the couch and is secretly hiding under the couch. He does this from time to time and I never know about it, however this time, this gas attack is one of the worst I ever had . I continue to sit on the couch, legs crossed, belting them deep into the cushion, trying not to wake anyone up and little do I know, my son is under the cushion jerking off to the sounds, yet I have no idea! Normally when this happens, he'll bust, I'll go back to bed and I'll never find out about it. This time however, the gas is SO bad, the attack goes on for SO long, and the sounds are SO deep, gulpy, long and multi-toned he has NO choice and needs to cum three times in row! Afterwards, I go back to bed and never find out about it.
