I was donating some things I had to a local thrift store this one day recently. The back door to my bronco would not open so me being as smart as I thought I was, I climbed onto the back bumber of the bronco to reach inside and pull stuff out, there were too guys standing there watching not far off to the side of me. Well I was bending inward, with my butt completely up in the air, when suddenly I had really bad gas and I realized I was about to blow a big one any second. And to make matters worse my pants were see through so my butt crack completely visible through my panties. I tried so hard to hold it back but before I could do anything to stop it....I let out a HUGE FART!!!!. It lasted about 50 seconds or so. My face turned so red....I was so embarrassed I didn't know what to do. To this day I still have flashbacks about that horrid day.
