Flashing (ians laptop find)

So long story short, me and Sue were out with friends sat outside a local pub on the grass. Sue was wearing one of those all in one short peices that looks like a short skirt but it's not.
As the day went on (sun getting hotter and hotter), so did Sue. She gave me a look that I'm fairly familiar with and I looked between her legs to see that her shorts were to one side and her knickers (g string) was almost inside her. Obviously this was turning us both on, mixed with the sun and booze. This carried on for a while. We both then went to the bar and she told me that some lads opposite had noticed and were having a good look. I asked if she was enjoying it and surprisingly she said yes. Thinking she would outright refuse I half jokingly told her to go in the toilets and take her knickers off and put them in her bag. She smiled and went to the toilets.
Back outside and her legs were getting wider apart, she was more exposed but making sure our friends weren't aware (they probably wouldn't approve). Her shorts were pulled aside again but now her lips on either side were on show to me and the men opposite. This went on for about an hour before the guys went and we all started making tracks home.
Back home we just had the best sex we've had in ages. She admitted openly that she was so turned on and wet showing her bits that had our friends not been there she would have loved one of those lads to come home with us. I asked if she would have had full sex and she said yes she probably would because she was so turned on.
I've not known her that wet in ages... she wanted to do everything.
Anyone else flashed like that or is it just Sue that loves it?
