On the Wednesday Peter picked me up at home as arranged on the mobile with Office-too mob. Officially we were off to the Midlands again and back late afternoon. The beach was about 2 hours away, after an hours driving we stopped to change out of our work clothes. Mine was a dress that would survive in the bottom of my work bag and Peter's a simple T shirt and shorts, also in his work bag. We had a quick knee trembler, we now call it 'saying hello' which gave me 3 or 4 quick, little orgasms as Peter slid into me before continuing the journey. In the boot was the picnic/beach bag. The beach was down a long bumpy road. It was nice and warm but not too sunny. We parked and walked about 100yds. to the beach. We walked around the bend in the road and saw the 'beach', it was actually the back of the dunes and dotted with large clumps of marram grass. The beach proper was through the dunes but it faced north and was on a muddy estuary so very few people went that side. A few people could be seen dotted about the beach, mostly as heads peering around the clumps of grass to see who had arrived. Right by a sign warning that clothing was not required lay a couple, about our age, both naked. As we approached the woman parted her legs to show that she had a smooth pussy and as I looked, swollen pussy lips. Peter also noticed. The man's cock was laying dormant along his thigh but it was quite a healthy size. We stood and chatted to them for a few moments while Peter undid the zip on my dress and eased it off my shoulders, it fell to the ground and I stood naked in front of them. I bent to pick it up and enjoyed the thought that anybody behind me would have a nice view of my bum and pussy. I stood up and held the dress in my hand down by my side. I never even considered holding it in front of me to cover my nakedness! Peter had seen me naked quite a few times in the past week and I had been naked, for him, in public places as you will have read but this was the first time I had been naked in full public view. It felt good! I tingled with pleasure from my finger tips to my toes. I could feel my nipples hardening as I felt all the eyes on me, assessing the new arrivals. I'm sure the guy's cock twitched and the woman said 'what a pretty pussy'. The guy agreed and I had a little cum on the spot. I remember thanking them without any embarrassment. Peter got naked quickly and we moved on along the beach, weaving between the grass clumps towards the dunes. I could feel all the eyes checking me out as we walked. We stopped to chat with other couples and a couple of guys on our way to the back of the beach. My pussy was wet and throbbing as more men, and a few women watched me. I loved it! Once we had found somewhere that Peter liked we set up camp, laying down the rug and picnic bag before sitting down ourselves to do our own naked people watching. I quickly realised that around us there was almost a full circle of interspersed clumps. Among the clumps, about 10 feet away, was a young guy, a little below us and nearly behind a clump of his own. Peter told me to open my legs more as the guy was trying to see my pussy while having a wank. I opened them wide. He liked that. Peter told me to lift my knees and let them swing apart. I did. He liked that too, I could now see his elbow moving as he rubbed his cock. Seeing that and knowing he was looking at me made me hot and horny. I was told to open my pussy lips and finger fuck myself. I did! I came a little as the lad turned to watch me quite openly. I was told to beckon him over and tell him I wanted to watch him wank over me. I beckoned to the lad who got up and, using his towel to cover his erection, walked over to us. I told him I wanted to watch him wank while I finger fucked myself and he knelt between my legs. He took his stiff cock in his hand and started to toss himself off. I pushed my knees as far apart as possible, held my pussy lips open with the fingers of one hand and slipped two fingers of the other into my sopping cunt. As the lad stroked his cock I finger fucked my cunt in time with him. I didn't wait for any more instructions from Peter, the lad was getting close to shooting his load and I wanted it on me! I told him to come closer and put my legs over his to encourage him closer still then I told him I wanted his spunk over my smooth, greedy pussy. I was fucking myself frantically by then and the lad was ready to shoot. He closed his eyes, groaned and thrust his hips forward and wanked and spunked hard and fast. Spurt after spurt landed bang on target. I moved my hands and held my cunt lips wide open as he pumped his spunk onto my smooth mons and it trickled down between my pussy lips. When he had finished I scooped up the cum with my fingers and looked at Peter who was smiling happily. He nodded and I licked my fingers clean before going back for more. Peter told the lad he could lay his towel beside us if he wished. I laid down, closed my eyes and relaxed. More if you would like it? Love Mary
