Whilst a student I shared accommodation with a girl who was to become my wife. Our house was on the outskirts of Chester. As our year progressed we became increasingly friendly and flirty. We enjoyed going to the leisure centre, Northgae Arena to swim. It has a free form swimming pool and I still remember the first time we went there and I saw Alison in her red swimming costume which had gone semi transparant.She was sat with her legs dangling in the water and her hard nipples were visible through the thin fabric and her dark bushy mound also stood out through the damp material. It tookk me a long time before I was safe to get out of the water. One Saturday she told me she was going there to use the sunbed. When she came home she seemed quite excited and that evening told me that she had been using the sunbed in the health suite and had been totally naked on there when a man entered the room and watched her. The sunbed had been in its own room but without a lock on the door and the guy had come in for his session early. She hadnt put the top of the sunbed all the way down and was lying on her back and must have been quite exposed when he walked in. She said that as he had come in he let his towel drop and she noticed he too had been naked and had a semi erect penis. She said he apologised and claimed not to have known anyone wes in there although apparantly the light of the sunbed , when used, should have been clearly visible outside. She said he seemed to take quite a while to put his towel back on and leave the room and she though his cock had seemed to twitch and grow a little whilst he was in there. She seemed to have enjoyed the experience and I was surprised not only that she had shared it with me but also that she had used the sunbed without a costume but also that she clearly was turned on by the unexpected interuption. It was after that revelation that she told me that as well as the sunbeds there was a sauna and steam room in the health complex and we agreed to visit it together in the near future....
