After a couple of 'coffee dates' where there was some obvious chemistry, she invited me on a picnic at the local beach. Walking along the sand with picnic basket, blanket and bottle of wine in hand, I'd barely noticed that many of our fellow beachgoers were naked. Nervous, but also aroused at the prospect of this voyeuristic opportunity, lay the blanket down and began to strip off. The sight of her delightful looking figure was enough for me to forget there were people walking close by. We started kissing... caressing... and before I knew it she was on top of me, riding my shaft with no care who was watching. I soon became aware of some talking just to my right and some heavy breathing behind me. Shielding my eyes from the sun I looked up and realised we'd drawn a small group of onlookers! 3 couples watching on, engaging in varied levels of petting, plus one fellow behind us looking like he was definitely going to climax before I did! Rather than shock me, it actually stimulated me even more. I felt like an athlete being cheered on to the finish line! Harder and faster we rhythmically reached a spectacular simultaneous orgasm. Falling into one another in exhausted ecstacy we lifted our heads off the blanket to see the crowd dispersing. We looked at each other and smiled, realising this may well have been the first performance of an ongoing exhibition...
