This happened a few years back. My wife brought her little niece to our community pool. As my wife is walking up the steps to get out of the pool, her niece grabs her to get her attention. The little niece slips and as she is falling she is hanging onto the wife's bikini bottom. She ends up pulling her bottoms down to about her knee's. My wife quickly bends down and yanks her bottoms back up. Even though this all happen pretty quickly, it was still a great show. Depending on your angle , you saw her red haired pussy or full view of her ass as she bent down to pull her bikini bottoms back up. My wife was a good sport about it seeing it was truly unintentional, but boy was she REALLY EMBARRASSED
Also, it was a very crowded pool day so I'm sure more than a few people saw the show
