Fun in the sun

My wife Liz and I have been into exhibitionism and swinging for some time although it is not an essential part of our sex lives. We do however every year holiday in Gran Canaria and particularly enjoy our trips to the nudist sand dunes of Maspolomas. There you can find all manner of activities however last year we enjoyed a most pleasant experience.
We were as usual keeping ourselves to ourselves at the hotel, spending our time relaxing , drinking and people watching. This particular day Liz was feeling very horny and so we took a trip to the dunes. We found a nice area and soon Liz had my cock in her mouth sucking for all she was worth and we soon attracted a small crowd of onlookers.Liz then bent over a large rock to allow me to fuck her from behind as I did I noticed that one of our audience was a guy from our hotel who was furiously pulling on his cock. I soon emptied my load into my horny wife and we made our way back to the hotel via a bar. Whilst having a drink I told Liz that of the guy from the hotel. She knew who I was talking about and asked what he was doing. I could tell from her tone that she was turned on by this.
Back at the hotel we spent the rest of the day soaking up the sun. Liz went to our room for a lie down so I took the opportunity to go and talk to our watching guest at the bar.
Despite an awkward start we soon got chatting. His name was Barry and he was 50 widowed and enjoyed the dunes something he and his late wife had done for years. He remarked on Liz and her lovely hourglass figure and said I was a lucky man and asked when we were going to the dunes again I said tomorrow afternoon. I left him at the bar and went back to our room. I told Liz about our chat and she said it was a real turn on to know we were going to be watched tomorrow.
That evening over dinner the talk was again very sexual and we were soon on our way back to the hotel . At the bar was Barry and we stopped and I introduced Liz to him we had a drink and prepared to leave Barry said see you tomorrow with a big grin on his face. As we made our way to our room Liz stopped and said why do we have to wait until tomorrow why dont we invite him to ours tonight. My cock began to stir at the thought and Liz told me to go and have another drink while she got ready. Barry was up for it and we downed our drinks and headed for our room. Liz was dressed in pull up stockings and high heels and nothing else she looked every inch a woman who wanted sex. She went over to Barry and planted a big kiss on his cheek stood back and said what do you think, Barrys bulging shorts gave her the answer. Barry and I were soon naked and under Liz`s instructions . As we sat on the sofa Liz layed accross our laps, her head and mouth in my lap and she was soon sucking on my rock hard cock. Barrys fingers were exploring her pussy and her tight arse and Liz soon came for the first time.We then swapped places and Barry enjoyed my wifes mouth around his cock for the first time. It was all to much as Barry called out i`m coming, Liz`s mouth just tightened around his cock even more and I told Barry to cum in her mouth. As Barry recovered Liz sat on his lap to allow Barry to play with her lovely 38 dd tits. I put her legs on my shoulders and began to rub my cock up and down her clit she came again in seconds before I slowly fucked her to another orgasm while watching Barrys hands all over her tits.We then adjourned to the bedroom where we pleasured Liz for another couple of hours including a very horny double penetration with Barry having the honour of fucking my wifes arse.
We had a great couple more days before Barry left but we are all booked up for this year for a repeat performance or three.
