It felt like all eyes were on us as we walked the 15 meters or so to the waters' edge, the pebbles loose under my beach shoes meant neither of us were overly dignified in this and Donna would squeeze my hand each time she slipped. As I neared the water I stopped and kicked off my shoes, angry at myself as I hadn't thought to bring a towel with me. I suddenly panicked that, as a cold wave crashed over my lower legs, this cold water might have a drastic effect on my manhood. I stopped and said it was too cold for me and that I'd paddle but Donna yanked my arm and pulled me in. The beach shelved and we both toppled into the icy water. In fact it was probably not that cold but the contrast to the near 30 degrees in the sunshine just made me go goose-bumps all over and I felt my balls run for the safety of my lower abdomen!
I swam about with Donna for about 15 minutes. It was a lovely feeling to swim in the nude and I made the most of it. I am a much stronger swimmer than Donna and in the end I had to give up swimming to assist her inefficient technique that had her getting battered by the light waves. He body was warm to the touch and, although I was not doing it deliberately, my hands were touching her way beyond what is allowed for 'friends', in my mind at least. We moved in close to sure and I was able to squat against the pebbles with Donna sat on my knees keeping her upper body out of the water. I was definitely getting hard for her as I held her soft waist firmly so as not to allow her to get pulled into the water by the tide. I knew I had to move as my dick would soon be digging into her buttocks.
I pulled us both up and out of the water onto the beach. I then made the awkward scramble to our footwear and once my feet were covered I took Donna over her flip-flops. I realised I was distracted by this gentlemanly task and so hadn't thought to look down at my penis to see how bad the cold water had effected my dignity. All in all it was not too bad. My balls were up inside me and me semi was poking out about 3 inches in just enough of a downward angle to not look I was erect. Donna held onto my shoulder as she put her flip-flops on and I had a great view down into her cleavage as she leant into me. The waves had moved her bikini top a bit and the top of one nipple was clearly visible. My ogling didn't go unnoticed though and I got a light slap on the arm and a telling off from her for perving over her 'wardrobe malfunction'; her broad smile leading me to believe the telling off was more for show than for real; and as she 'fixed' herself I got a brief glimpse of one full pointy nipple.
Once set I went to head back towards Nikki but Donna grabbed my arm and once we were holding hands she pulled me along the water's edge. I felt very exposed as we walked slowly along the waterfront with literally hundreds of people looking our way. I was pleased to see I was warming up and my balls were coming back out but I did feel like I was on show for them all and they all were having a look. My only saving grace was that I was hand-in-hand with Donna, meaning for the lonesome straight men at least, I was possibly being looked upon with envy. Her nipples were poking through her top like pen lids and she was swaying her hips more than necessary as we walked.
As we neared the edge of the nudist zone I could see many clothed people just outside the imaginary line. Many, if not most, were women and I had to take another quick look at my package to know if was going to be embarrassed some more. I now had a full set of balls out on show, but my dick was down to just a couple of inches, albeit a fair bit fatter than normal. I had to live with what I had so stood tall as we left the nude section fully. I pulled at Donna's arm and said we were now out of the nude area but she pointed out a naked couple who were a good 20m further along. Donna said on busy days people spread out more and it was the norm. So she dragged me along past all these people who were definitely looking at me (us). I felt almost overawed by this unplanned exposure and felt I might shrink back further so didn't even look.
