I am "Carol". Yes, it all happened as "Lee" described it (I'll call him that here). That was quite a day and I am not ashamed. That was a long time ago, a little more than thirty years, I'm a different person now but I always smile to myself when I think back on that day at the beach. I think Lee did an accurate job of describing the events, and a fair job of describing my feelings during and afterwards, but that's the part I think needs more explanation—my feelings and why I did what I did. Probably nowadays such behaviour is more common, but in those days this was risky and unusual. I prided myself then as I do now for having taken such a risk and making myself so vulnerable and triumphing over any negativity. But what I want to say here is that at the time, I was trying to overcome all the inhibitions I'd been taught by parents, church, school, society. I wanted to rebel even if it meant consequences, I wanted to flaunt the norms of my upbringing even if it meant I'd have to define myself in a whole new way, I wanted expose myself even if it would leave me no place to hide.
Before meeting Lee at the lab, I'd had many boyfriends. If I liked a new guy and saw potential, I'd fuck him on the first or second date (I always called this my "invitational", or "trial" fuck. This was so I'd know if we were sexually compatible. That was the most important thing to me, and I wanted to get that question out of the way. As a grad student I didn't have a lot of time to waste. (Note: we wouldn't even have a first date if he wasn't attractive in the first place; the guy had to be confident, secure, have a good personality, be financially responsible, sensitive, all the rest of the desirable things before I'd even be interested. Those traits had to be apparent right away, before getting to dating. If he got a first date, he probably got a fuck.) Back to the sexual compatibility: I love sex, and wanted a good fit. The cock must fit me and not be so big as to hurt, and not so thin as to slip around too much, and not so short as to not reach inside me far enough. Also, once inside, I want the top part of his shaft to put pressure on my clit. This can be learned later, but the fit must be there to start. If all these things don't come together on the first try, we might continue to be just friends but I'll look elsewhere for sex. Having a large number of first or second dates that didn't work out sexually taught me a lot about guys, but mostly confirmed to me what I like. With Lee, everything came together just right on the "invitational", so I moved in with him for the rest of the summer.
That should clarify about the sex. Now, about the nudity: I'm not a nudist. I don't take my clothes off unless it's to shower or to sleep or to fuck. If you saw me naked on the beach that day, it was because I was fucking. That day I really didn't consider my nudity or even my fucking to be that private.
What I did try to keep private was my orgasms, and it took me a while to be able to willingly share them with onlookers. At first I tried to hide my face as I came, but eventually I realized that my seeking humiliation and vulnerability could be successful only if I shared the most intimate, private, part of me: the feelings you could read on my face as I climaxed. That is different for every woman, and for me it is sharing what I alone can give. I made myself very vulnerable by inviting strangers to make eye contact during my orgasms. If anyone had ridiculed me at that critical time, I would have been devastated—this was the risk I wanted to take. Remember, as Lee wrote, I was doing this without alcohol. I was completely sober and well rested. I was completely aware of what we were doing and could have stopped at any time. I wanted to do something that nobody else had done (at least at that time and that place): put the most private, intimate part of me out there for all to see, and take a chance on being rejected or humiliated. As it turned out, it was thrilling.
Let me tell you a little about getting ready for the beach: I knew I wanted to expose myself, but at the same time I didn't want to appear as cheap. So the day before, I got my hair done, putting it up in a really classy bun in back with a few strands forward, and painted my nails. Before leaving for the beach I did just a touch of make-up, and put in tiny earrings and a simple thin necklace with a single pearl. I could have just as well be heading for high tea, except that I also removed all my pubic hair. (This was a bold move for the times; very few women did this back then. But then remember, the aim was to expose myself, and I didn't want to be hiding behind a patch of hair.) Funny that Lee didn't mention this in his narrative. I wanted all of my pink to show. He did mention about holding myself open, I'm just surprised he didn't dwell on the exposed lips and the pink, like most guy writers would.
As we got near the beach, I felt a mix of excitement, dread, adventure, terror, but never once suggested turning around. This was something I was determined to do. (By the way, Lee led you to believe that we'd just heard about this beach. Well, I didn't let Lee know at the time, but I'd been there several times earlier in the summer with other guys I was trying out. Since those were first or second dates, I did fuck a number of them as "invitationals", but up in the dunes where we couldn't be seen. Otherwise I kept my suit on. In those cases the invitationals didn't work out, so I moved on. I saw people were nude, but no sex. In fact, seeing no sex there gave me an incentive to do this, but only at the right time and with the right guy—someone who could pass the invitational.)
Back to our drive there: all we had with us was a sheet, a couple of towels, some soft drinks in a small cooler, sunscreen, and a sun umbrella. The calendar was good for me, so we didn't need condoms, which I hate anyway. After we parked the (borrowed) car and were on the footpath down to the beach, we planned how we were going to pull this off. We decided the best thing to do was to get to work right away before anything could dissuade us. We'd best set up right where the path gets to the beach, so as to not get distracted and also to make sure any new arrivals would see us. So, we figured we'd arrive on the beach, spread out the sheet, strip, and (literally) mount up.
And that's exactly what we did. At first I had to put myself in the frame of mind that we were alone, so we took up a position with Lee on top. I asked him to not move, but just lie there inside me, I would do the moving when we'd be seen. It was easy to not move around, since I was terrified knowing that someone would appear soon—well, wasn't this what I'd planned? My feelings of humiliation were overwhelming, even with no one around. I was lying naked on the ground, looking up. At least on the main part of the clothing-optional beach you could do this, but then so is everybody else. And they're not fucking! As I heard rustling along the path, I knew someone must be approaching, and I was completely freaking out inside my head but trying to remain calm on the outside. I was not just lying there naked and looking up, I was lying there naked and looking up and fucking! Since we were right where the path empties onto the sand, it took less then a minute for three guys and two girls to appear out of nowhere, and they were now about a meter from us. I'm lying there naked and fucking and looking up at them looking down at me lying there naked and fucking and looking up at them. This first encounter was the most thrilling, terrifying, humiliating, and exciting I had ever felt in my life. In my mind I was screaming, but my mouth was too dry to utter anything. Lee was on top of me looking down, so he couldn't see them; this terror was all my own. I felt so vulnerable—what if they laughed at me, or kicked sand in my face, preached the bible at us? Time just stood still, until I broke the stop-frame by drawing my legs up around Lee's hips and arched my back a little. This brought smiles from our visitors, and they moved on.
