Whilst on a recent holiday in Playa del Ingles in Gran Canaria, my wife and I decided to use the hotels spa facilities. The majority of the guests staying in the hotel were either German or Dutch and the hotel also had a naturist sun bathing area. By the way my wife is 34 years old, 5'5" tall and weighs around 9 stone and is a size 10, she is slim with small breasts. I am 6' 1" tall, weigh 14.5 stone and unfortunately don't have a super sized cock, only 6" fully erect. But even though its not the biggest, it works and both my wife and I like it. We put our swimming suits on in our hotel room and put the hotel robes on and headed to the spa on the ground floor of the hotel. We we arrived at the entrance to the spa we were each given a towel by the girl on reception. From our accents she realised we were english and she told us to read the sign on the wall. It said in that the spa was used by guests from all around the world who had different customs when using the spa facilities compared to the english and that we should not be offended by nudity. My wife was a bit hesitant to enter, but I gave her a little nudge through the glass entrance door and we were in. Directly in front of us was a Jacuzzi, a sauna to the right, a steam room, showers and relaxation area to the left. There were two young women in the jacuzzi, who I could see were topless and a naked man in the showers. We both disrobed and removed our swimming suits and hung them up, and walked naked into the jacuzzi. I asked my wife how she felt being naked, she said she was fine as everybody else was naked to. The two women then stood up and left the jacuzzi, to reveal they were also completely naked and shaven, like my wife. They then went into the sauna opposite. I told my wife that I was going to try the sauna to. She said she would stay in the jacuzzi, so off I went. On entering the sauna I could see the that the only occupants were the two young women, who were lying on their backs talking to each other in german. I sat on the bench opposite the door. The door was made of smoked glass, you could see out, but you could not see in. From my position I could see my wife sitting naked in the jacuzzi, if I glanced left, I could see two young germans lying on the top and middle benches of the sauna, naked, with their feet in my direction. This gave me a perfect view of their shaven pussies. I was starting to get aroused! Suddenly, I noticed that the naked man that had been in the shower when we arrived at the spa had climbed into the jacuzzi and was sat next to my wife. They were both facing me, I could see them but they couldn't see me. They seemed to strike up a conversation, my wife naked talking to a naked man. I got even more aroused and now I couldn't hide it. I was sat in the sauna with a full erection! The two german girls were lying down only 3 feet from me, but were not looking in my direction, so I began to slowly wank. The thought of my wike naked with another man, two naked women only inches away from me. I couldn't help my self. I started wanking furiously and after only a couple of minutes, my cock exploded all over my chest. The two girls in the sauna, never moved a muscle. I had managed to have a fantastic wank, inches away from them without them noticing. I got up and left the sauna and entered the showers, my wife said goodbye to the man in the jacuzzi and joined me. We both dried, put our robes back on and headed back to our room carrying our swimming suits. As we travelled back to our room we were naked under our robes, so we kept daring each other to leave the robes open, exposing our bodies. My wife got caught twice!!!! When we arrived back in the room, I told her what I had done in the sauna watching her talking to another man when they were both naked. She told me that the man was french and that when he was talking to her, his hand was on her leg under the water, moving up and down the inside of her thigh. I asked why didn't she move away and she said initially she was too scared to move, but after speaking to him for a few minutes she began to enjoy it. She said that he told her he goes down to the spa at the same time every evening, whilst his wife has a sleep before they go out in the evening. So the next night and every night until the end of the holiday we went down to the spa. My wife would sit in the jacuzzi with the french man and I would wank in the sauna. Eventually the french man moved on from just touching my wife's inner thigh to fingering and wanking her pussy and she would pull his cock and I watched it all from the sauna!!! What a holiday.
