Maybe another time I will recount our further two visits to Helios and exactly what happened there, but suffice it to say had we stayed in the area we would have definitely taken up a full membership. However our training contracts both expired around the same time and we both moved back up to the north west. We got stuck into our professions and bought a house together and probably a couple of years passed without any further experiences apart from visiting clothing optional beaches on Ibiza, either at Playa d'en Bossa or the official naturist beach at Es Cavalet. One Autumn weekend we decided we were missing the sauna scene and noticed there were Saturday afternoon naturist sessions in the Northgate Arena, where of course our initial experiences had started. So we decided to take the plunge again. The familiar butterflies were present as we paid for admission to the couples only session and went up. There were perhaps eight or nine couples and we would quickly recognise that most were regulars. We were the youngest couple by quite a bit, most of the others middle aged and several with guys who seemed to have slightly reluctant wives who would spend most of their time in the lounge area wrapped in towels only occasionally visiting the two sauna cabins in the adjoining room. It seemed strange stripping off together in the communal changing room and often mainly guys would wander through ostensibly visiting the loos but I thought usung the opportunity to watch Alison disrobe. The sauna in all other respects seemed quite proper, with couples mainly keeping to themselves. This wasn't a problem for us, we were quite happy just spending our time naked with others. However after a few visits we were clearly becoming regarded as part of the regulars and a few of the couples became more approachable. There was one couple Bo and his wife Ann who seemed to be always there. Towards the end of the sessions Ann and Alison would tend to frequent the lounge while Bo and I would remain in the sauna. On one occasion when we were the only two remaining Bo started telling me about another of the regular couples John and Lesley who were swingers. When I didnt make a derogatory comment he went on to tell of some exploits that had occurred and had also involved Bo and his wife. He told the stories well and it wasnt long before I got a raging hard on, which he noticed and commented on. Others came in at that point and I rushed out to the plunge pool to cool off. The following week both John and Bo and their respective spouses were there. I thought something must have been mentioned between them as John and Lesley were much more communicative with us than previously and when Alison and I went to the showers in the sauna room immediately prior to entering the sauna John and Lesley came over. There was only one remaining shower available, next to me. They both got in together, which was quite unusual for the venue , as we had realised it was a more traditional naturist crowd. As Alison and I got out of the shower John and Lesley followed and we all entered the sauna at the same time closing the door behind us. The sauna was quiter packed with few spaces. John and my Alison both found gaps on the middle tier seperate from each other and sat on their towels. That just left the bottom row with a four foot expanse of bench right by the door. As such Lesley and I settled down next to each other. Everyone facing the same way back towards the door we had just come through. After a few moments a couple from somewhere behind us left passing between Lesley and myself. I stood up to let them past. As they went past and I settled back down Lesley sat down where she had been but this time sideways facing towards me but with her left leg up on the bench giving me a clear view of her pussy. As I was sitting I too turned to face her mirroring her pose so she had a clear view of my cock. Nothing was said and to all intents and purposes everone was behaving properly. The inside of the sauna was quite dark but close to the glass door we had a better view than those further in the sauna. I was sure that John would be able to guess what his wife was up to and I darent look at my Alison. I started to wonder if I was misinterpreting the situation as everything remained silent and normal and then I felt Lesleys foot touch mine. Our eyes met and she glanced down, I followed her eyes down and saw her pussy lips twitch as she contracted her pelvic floor, I looked up and she gave a mischevious wink and I bacame instantly aroused. At this time Alison and I would have been mid 20's and Lesley was well into her 50's but had a very trim body and clearly exercised well and took good care of herself. I let me semi twitch and start to grow aware that Lesley had a clear view of it but my raised leg meant that others in the sauna couldnt see what was going on. We kept this up for what seemed ages waiting for someone within the sauna to shout and complain but no one seemed to notice. It was probably only a minute or so before my bottle went and I exited the sauna with my towel clutched around my cock. The couple who had left moments earlier were in the plunge pool so I rapidly went to the shower and turned it as cold as it would go and faced the wall until my erection subsided. Later John approached me in the lounge and started conversation asking me if I found Lesley attractive. I said I thought she was very attractive and he said something which made me realised he was aware what had gone on between Lesleyand myself in the sauna. He told me they were from Stoke on Trent and they often practiced naturism at home as their house was quite secluded and in its own grounds. I said that must be nice as we lived on an estate and there was no way we could be as free as we would like. He suggested our wives spoke and if we wanted we should come over for dinner sometime. I said I'd talk to Alison and let them know. As the session was drawing to a close most of the couples, John and Lesley included had left. A fewcouples remained including Bo and Ann. My Alison left to get changed first as it always took her longer to dry her hair and get ready. Ann and the other couple also left leaving just Bo and I in the sauna. He said he thought he had noticed something between Lesley and myself and I tried to pass it off. He said John had told him of the invitation to their house and said he thought Alison and I should go as they were often some wild evenings at John's house As he was telling me this I noticed he started touching his cock, moving it from one position to another. I guess he was testing me to see if I would tell him to stop but I didn't, maainlly becuse I wanted to hear more about these parties and what may be in store for Alison and me. As Bo went on he touched his cock more frequently and from something quite insignificant it grew into quite a long cock with a long uncut foreskin I too was starting to become aroused, thinking of Lesley and John naked at their house and what had gone on earleir in the sauna but also wondering if Bo went to these parties and if so what happened..........
