As a young man I went on a summer holiday to a health resort in the mountains. This was a small chalet style resort with something organised each day with all guests expected to participate. On the second or third day I opted out of the bush walk planned for the day as an old ankle injury was playing up. I spent a couple of lazy hours reading and then thought to take a sauna. As I was the only guest left in the chalet, I showered and, wrapped only in a towel, went down to the sauna. When I arrived, I thought it strange that it was already hotswitched on, but took no particular notice. I entered and after laying out my towel on one of the benches, I lay down naked to enjoy my sauna.
I soon became a little soporific from the heat and so my mind was miles away when the door opened and someone walked in. I woke suddenly and tried to cover myself, while struggling to sit up to greet the newcomers. I recognised them as the cook, Helga and her husband, Sven, the night manager. Sven said "Sorry, Rob, we thought that all guests were out for the day, otherwise we wouldn't have attempted to use the sauna. We will leave now and not disturb you."
I replied "Don't be concerned, I thought that I couldn't finish the walk, so declined to go out today. I don't mind sharing this place with you, in fact it is a bit quiet and I would appreciate the company. Come on in."
They both accepted this and entered, closing the door behind them. While I was still sitting trying to cover my nakedness, Helga shrugged out of the towelling robe she was wearing and placed it on the lower bench opposite me. She was now stark naked and was totally unconcerned that I was there as she lay down on the robe covered bench. Sven also removed his towel and having placed it on the bench above Helga, he climbed up naked to the bench and lay down on his back. This gave me some reassurance so I rearranged my towel and lay down also. We began to talk quietly and they said that they often sneaked into the supposedly guests only sauna when all the guests were away for the day as they had been accustomed to their own sauna back in Sweden where they came from.
After a little while, we were all sitting on the benches with Sven sitting alongside Helga and facing me. I noticed that Helga had only a small tuft of pubic hair above her pussy which was otherwise quite bare and that Sven had no hair on the shaft of his cock or balls, but only a thin band above. Both were quite unconcerned about their hairstyles. By now I had been in the sauna for quite a while so I went out to take a cooling shower. When I returned, it was obvious that they had been talking about me because they suddenly stopped and glanced at each other. I noticed that x/Sven's penis had grown a little and that Helga seemed to squirm around. I resumed my position opposite them and we chatted again about inconsequentialities until Helga suddenly realized that I would need lunch and invited me back to their cabin to share it with them, saving her the need to open the main kitchen. I accepted.
