I don't know what it is about imagining my wife with other men that excites me. I have always been fascinated by the thought of group sex ever since I was a teenager out on double dates with other couples. Of course it was always quite innocent and normal in those days to go out in a foursome to the pictures or whatever but in the back of my mind the seeds had been sown.
When I first started going out with Sheila I was in love and very possessive but after about a year we struck up a friendship with a school friend of mine. Trevor and his girlfriend would take us out in the car and we would to go out to various places of interest such as stately homes or go on country walks etc. On the way home we would stop at secluded spots for separate snogging sessions with our respective partners, Sheila and I in the back seat, and Trev and his girl in the front. Soon I started having fantasies about Trev and my girlfriend which included me guiding his cock into her. This was all quite naive and of course nothing like it ever occurred in reality but looking back I was a cuckold in my mind even then.
Sheila was quite petite with lovely blue eyes and the best thing about her was the fact that she always looked about five years younger than she actually was, an innocent schoolgirl look that men found irresistible. Even after we were married we were stopped by a policeman on our way home and he asked her if she was running away from her parents, as it was quite late, but I knew that what he really wanted was to fuck this gorgeous young girl! I used to get jealous when this sort of thing happened but it would excite me as well.
As sex with Sheila became more familiar I would verbalize my fantasy and talk to her about having another cock in the room and told her that I knew when other men found her attractive as she flirted with them, and that they would probably masturbate and think about her as they did so. I used to tell her to imagine having another cock to suck as I was fucking her and we used to come off very quickly as our imaginations generated images of multiple penetration.
As time went by I decided to join the army and, after the birth of our second child, Sheila and I set up home in married quarters. About a year later we were posted to Germany and the scene changed quite a lot. All the single men of our unit were housed in barracks and as Christmas approached the married personnel were asked by our Staff Sergeant if we would invite one or two of the single men to Dinner, as they would be away from their families over the Christmas period. At that time I had befriended a young man in our section whose name was Phil, we seemed to share quite a few interests including the same taste in music, so I thought there would be no harm in inviting him to our home as a friendly gesture, Phil accepted.
In the army we used to play a lot of sport and of course there was a lot of laughing and joking in the showers after football, mostly about sex, and quite a lot about cock size. Phil, it seemed was a legend, people claimed that he had the biggest cock in the battalion, and having witnessed it a few times in the showers I could easily believe it. I swear that this fact did not enter my conscious thoughts as I invited him to dinner that day, but who knows what goes on in the subconscious!
A few weeks before Christmas our section organized a trip to Dusseldorf for the lads, and we all piled on the bus that was to take us there and Phil and I sat together on the way. We had arranged to go on the bus with everyone else then make our way back later in the evening by train. We got split up and I mooched around the city all day alone then met up with Phil and some of the others at the railway station.
In the compartment on the way back one of the lads produced a newspaper from his bag. It was not an ordinary newspaper but contained sex stories in English. I read this story about a man having his wife gang banged and it really turned me on and I am sure that Phil noticed my reaction to the article.
Sheila was barely twenty-two at the time and she still looked after herself, in fact she was quite stunning, and the sort of clothes she wore emphasized her little girl image, in fact she looked about fifteen. Our sex life still included my fantasies about other men but Sheila seemed as if she was just putting up with it rather than contributing in any way.
Christmas day arrived and the usual stuff happened, the kids were both excited about the expected arrival of our guest. Phil turned up bearing presents for the kids and we felt grateful for his thoughtfulness. After dinner we played board games and listened to music and enjoyed watching the kids with their presents. Later that evening Sheila put the children to bed and we all relaxed a bit I topped up everyone's glass and the three of us started to get a little bit tipsy.
All the TV stations were in German so we couldn't watch TV. We started to talk about the nightlife in the town and Phil said some of the lads had gone to a bar where they showed blue movies and this interested me a great deal. Sheila showed no interest at all in this, but I said I would love to go one night. Phil then came up with a great idea, apparently some of the lads had clubbed together to buy a projector and he said they wouldn't mind if we borrowed it sometime. I immediately pounced on this saying there was no time like the present. Phil and I went off to the barrack rooms to locate the equipment. Sheila gave me a disapproving look but we went anyway.
When we got back we set up the projector in the living room, Sheila was getting quite tipsy by now and just sat in silence as the first movie came on. In those days before video you had to turn off the lights to see the film so it was pretty dark in the room and I couldn't really gauge her reaction too well. It was strange sitting there almost as if I were alone not daring to look at the two others in the room, but really wanting to know how the movie was going down.
