I'm sure there are a few, but here's one that I remember for now.
It was quite some time ago, probably about 9 years ago or so... It was night time and I was sitting outside by the lake on a blanket with Osiris' ex-girlfriend(who was my friend) and another friend of ours. Osiris was sitting in the car because he wasn't feeling well.
We were drinking vodka and grape juice and getting quite drunk at this point.
Then the other friend decided that he was going to go sit in the car to talk to Osiris, so, we girls were left alone. (Or about as alone as you can be when you're sitting outside in a public place

)
So, here we are trying to think of a way that we can amuse ourselves and have a little fun. We had decided to play a drunken game of Truth or Dare, which didn't last long before it got sexual.
Now, I have had sex in public places plenty of times before, without revealing anything, but this was a bit different.
Before I knew it I had my pants completely off and she was tonguing my pussy! (In plain sight of everyone, I might add.)
Which was awesome, of course, until a patrol car with flashing lights drew nearer to us.
I'll never forget the way my heart jumped as I scrambled to try to put my pants back on or the way I sighed with relief that it drove straight past us.
Then, of course, after it was gone, we were right back at it again.
