Several years ago we were on vacation and decided to go to a nude beach. When we got there, it was fairly empty, and by the end of the day we were the only ones left. Except for two other guys who were locals.

Now, something to understand about this beach is that it's lined by cliffs, and there are caves every so often that are large enough to accommodate several people. Almost as soon as it was just the four of us left, I saw the wheels in her mind starting to turn. Before long, she made her move. She got up and made a show of parading into the water, making sure the guys noticed her amazing ass and tits. Once she got out, she grabbed my hand and led me into one of the caves. Immediately upon getting there, she dropped to her knees and started sucking my dick. The guys, taking the hint, followed behind us soon afterwards. In no time their dicks were hard and they were positioned on either side of her. She spent a good 15 minutes sucking us all, then demanded that we fuck her right then and there. For the next 30 minutes we took turns on all her holes, even going so far as to DP and DVP her. One of the other guys and I came in her pussy basically at the same time, and a few seconds later the last guy came in her mouth. She swallowed, of course. As soon as we were done we all parted ways, and I don't think we ever even got their names.

100% true story, and I'm very proud of her.
