The (then) partner and I were down the beach doing a spot of nude baking on a local beach, when the horny desires took over us. We were not too far into the dunes and were fairly regular in this spot and well aware of the passing foot traffic. But the heat of the sun and the pure horniness took over and we started going hard at it. I glanced over his shoulder as he was eating me and saw 3 dudes with their cocks in hand a little way off. None made the move to come any closer, but off to the side was another dude, slowly edging closer to us and making eye contact with me. My (then) partner asked me if I was interested in letting him join in.......... Part of me did, but as we had no condoms with us, I only allowed the bold dude to eat my soaking wet pussy whilst the other three watch, as the stranger ate me, and I sucked off my (then) partner. At the time it was the naughtiest thing I had done, and was totally exhilerating.
