We have just come back from a friends apartment, Ray, in Spain. He told me about a nudist beach close to a popular beach he told us to go to. On our first day we went to the beach at about 11 am where there where loads of sun beds to choose. My wife Sally, 35, 36c tits and a smooth pussy. We settled down and Sally took her bikini top off and put her oil on. It got me semi erect under my trunks just watching her oil up her boobs. We then laid back and took in the rays. After about an hour and a half I went for a swim to cool off. When I got back to Sally I told her I was going for a walk along the beach to dry off and also check the beach area Ray had mentioned. I walked for about ten minutes and started to come across naked people. I had never been to a beach before where it appeared the norm to be naked. The women came in all shapes and sizes. Most where laying on their backs with their legs apart with everything on view. I saw some nice tanned shaved pussies. Most of the men laying with the women had semi erect cocks, all on display for those walking by. I then came to area that had some dunes at the back of the beach and a bit further up it changed into a more male couple area. I decided to walk back but along the top of the dune area. I also decided to take my trunks off and allow the air and sunshine onto my prick and balls. I got to a area on the dunes where there was a few bushes. I looked down and saw a naked male sitting and wanking his prick. He appeared to be looking at something. I moved down and looked over a low bush and saw what he was looking at. I saw a naked couple, both aged about fifty. She was on the plump side with very large boobs, about 44 inches. She was sitting against the bloke, who had his arms around her massaging her boobs and nipples. She was playing with her clit. They appeared to be putting a show on for the bloke wanking. He said something to them and she then beckoned him down. He then went and sat in front of them while they continued to play. He was still wanking his prick. He then started to edge closer to them. I was now wanking my prick, I took over his position he had left and had a good view of the action. The bloke ended up in between her legs, on his knees wanking right in front of her as her partner continued to play with her tits and she fingered her pussy. She then started to moan. The bloke wanking his prick stood up and she then moved both hands and placed them under her boobs pushing them up as the bloke came shooting his spunk over her boobs. He thanked them and walked away. I sat there for a couple of minutes to see what they were going to do next. I looked to my right and saw another bloke arrive. He had a deep tan and had a large cock hanging down in between his legs. It looked about eight inches and was not hard. He stood there for a couple of minutes watching the couple and started to wank his prick. I looked back at the couple. She had now got on all fours and was giving her man a blow job. The bloke next to me went down into the dune and sat behind the woman, about four foot from her arse. His prick was now erect and stood at about ten inches as he rubbed it with slow strokes. The woman looked behind her and saw him. She looked up at me and beckoned me down. I went down and sat next to the bloke with the big prick. I had never wanked in front of another man before, but the sight of the woman's pussy and her giving a blow job to her man was really sexually exciting. The bloke next to me then opened a bag he had with him and got out a condom. He rolled it on his prick and got behind the woman. He tapped her on her bum, she looked round, her partner looked up and they both nodded. The bloke then eased his prick into her pussy and fucked her. As he fucked her her tits swayed back and forth over her partners face and he licked her nipples. The bloke fucking her came and withdrew. He indicated for me to take his place and gave me a condom out of his bag. I had been married to Sally for 15 years and had never cheated on her, but the air was full of sex and temptation was too much. I grabbed the condom, put it on and entered the woman. I felt her grip me with her pussy as I fucked her. I only lasted about a minute and came. I withdrew, thanked them and left. As I walked back I came across another area of secluded dunes with more naked male and female couples. I had a look and saw one couple laying on their backs and the female wanking her partner. Another couple, the male was fingering the female. All these acts were in the open and it appeared if it was the norm for them to let others watch. I decide to go back to Sally. She asked me about the beach and what it was like. I told her there was a lot of sex going on and confessed to her that it had been to much for me, watching others fuck and play with each other gave me a hard on and I had to wank and come as I watched them. She then said after lunch she wanted to see. We had lunch and packed up our gear and left to go tho the dune area. As we got to the start of the nudist area I took off my trunks and encouraged Sally to take her bikini bottom off. She told me she might later. We walked past quite a few naked bodies. Sally did comment on the various sizes of penis and how some looked erect laying on some men's belly's.I took her to the top of the first dune area we came to. The first naked couple she saw were already fucking. The bloke was on top of the woman. They had about four blokes watching them. Sally was amazed that they were fucking in the open and letting people watch them, especially blokes and how they were standing in full view of everyone and just wanking their pricks. We stood there for five minutes, about ten foot away watching the couple fuck, he came and rolled off her. His prick hard and shining with love juices. A couple of the blokes came, shooting their spunk into the sand, the others just wandered away. It was then that Sally realised she was the only woman voyeur. I asked how she felt and she told to look at her bikini bottom. I looked and saw a damp patch. I asked her if she wanted to see anymore and she told me yes. She told me she thought it was quite sexy and thrilling to see others having sex. As we walked away from the couple Sally took her bikini off and we both walked along naked. I had a semi hard prick, which Sally commented on.She then said, "Did you feel like you wanted to fuck me as we watched that couple?" I then asked if we found a quiet area would she let me fuck her. She told me not today but perhaps later in the week. She told me that that she would like to watch others first and build up having sex in the open as others watched. We went to the area where I had seen the first couple. They had gone, thankfully and another couple were in the dune. They already had four or five watchers. Sally became quite keen to seen what was going on and went and stood in between two men wanking. She looked down into the dune and saw the female being fucked from behind, with another male on his knees in front of her being given a blow job as she was fucked. I stood next to Sally, put my arm around her and grabbed her right boob and played with her nipple. She took hold of my prick and wanked me. The bloke to her right moved closer. I took my hand off her tit and went between her legs and from behind found her moist pussy and fingered her. We were both mesmerised with the sexual surroundings. The woman being fucked gave a loud moan and the bloke fucking her shouted out. She pulled her face back as the bloke she was giving the blow job to came over her face. Sally was gently moaning. I looked down and saw that the bloke next to her was sucking her nipple. I came and felt Sally's body tremble as she came and I felt her pussy tighten around my finger. The bloke next to her came and shot his spunk down her right leg. We both felt highly charged as we walked down to the sea to wash our bodies. Sally told me she did not know why she did not feel ashamed or guilty about watching other or even allow another man to fondle her while I was standing there. We both felt it had been right and would see how the next few days panned out and how far we would consider going with others. I will continue with our beach sexcapdes later.
