We both worked in a Yorkshire City and were in our early twenties. My wife Sue worked in a national High Street store where she formed a friendship with a local girl. After a while we and her friend and partner met on a night out in town and discovered her friends partner Tom came from a nearby village where we had lived during our childhood. We all hit it off and became very close friends and as our children grew we did things together . However my job took me away from the city and we moved nearer the coast but kept in touch with our friends and often visited and stayed at their house and they visited ours. I noticed my wife and Tom were often complimenting each other and I could see there was an attraction between them. One night in bed we were masturbating each other and telling each other our fantasies, as you do, getting very excited when I happened to mention that Tom obviously fancied Sue. I could tell she was responsive to the idea and she came when i said do you think he would like to fuck you. This became a regular fantasy of ours and we would both come hard thing about Tom having his way with Sue. One visit between us, we all went to the swimming baths with our respective children and Tom took his boy to the male changing rooms with us and the ladies went into their own. My heart skipped a beat when Tom took off his clothes to put his trunks on, to reveal a very large member between his legs. Nothing was said but it made mine look a second best in the scale of size. Later on when back home I mentioned it to Sue who looked stunned when I described Tom's cock to her. She asked for every detail asking if he was hard etc. Of course I said not, just normal lads changing together. Every night after, Tom's cock became the focus of attention when Sue and I made love, she became obsessed with his cock and wanted somehow to see it, just to see what it was like. This made me horny and I came off every time knowing she was interesting in someone else's cock and clearly wanted it. Conversation eventually worked around to the possibility of Tom fucking her if the occasion ever arose, I asked if she would let him fuck her. At first she said no but as time went on she clearly wanted to and admitted she would if I was ok with it and would not be jealous. Secretly, I had pangs of apprehension but I wanted him to fuck her more than she did. I couldn't think of any thing else, the idea occupied my mind constantly. So, the idea was planted and we both got off on the idea it would happen at the first opportunity Time went on and after about six months we went to visit them in the City and were to stay over the weekend. Sue was very excited about our visit and we had discussed that if the the time came then I was ok with it and she should go ahead and let Tom fuck her, with my blessing. Oh my, I was hard as rock even thinking about it. Typing takes longer than you realise so will continue this later if there is any interest,
