So going back a while, I was 23ish, not particularly polite, and my bf of 2 years was giving me a rim job - my first...and last from him because of this little indiscretion.
After about 10 min of fighting to keep my ass bubble tight while his tongue played the hokey pokey something just snapped and I suddenly decided I was gonna burn the mustache off his face. I lifted my head, watched for just a moment and then cut loose a massive fart that smelled worse than cat shit. His head jerked up as if electrocuted. He looked at me stunned, with a crooked half open mouth, one eye larger than the other, and completely paralyzed for a few seconds. It was EXACTLY like a Warner Brother's Pepe Le Pew cartoon as Pepe walks by the shop keeper. I started laughing almost hysterically and couldn't stop - and yeah, he was pissed off. Days, weeks, even months later someone would fart or make the sound or hell just out of the blue the event would cross my mind and I'd bust out laughing. It was the funniest damn thing I'd ever witnessed to that point in my life. Even now, I have tears streaming down my face I'm laughing so hard as I recant the tale here. Yes it was really rude, but I was young & stupid back then.
