Girls do that kind of stupid shit all the time though. They know its dangerous (because of wind and stuff) to even wear a thong n skirt but do it anyway, to feel naughty, to fantasize they can have an accident and random dudes are going to see their bare cheecks. I read that kind of shit in women forums or even cosmopolitan blogs. Girls are crazy.
And society too. Its ok for them to play with our hornyness but not ok for us to take advantage of that.
Her farts have zero barriers to contend with, when she sit down her bare ass is on seats leaving butthole pucker marks all over. You eat her ass after a long day your eating every other ass that were in the same seats she was.
