This started a long while back. I was in my mid thirties when a woman joined our them at work. It was still pretty much a male environment then. Liz was quite good looking and acted slutty and used bad language to fit in with her male environment. In fact she went further than was really needed. We tended to work in two's but I hadn't worked with her. It wasn't too long before rumors started that either she was getting shagged by my team mates or she was a lesbian. I knew she wasn't the latter because she had a husband and three kids. Work was often hard and I was looking forward to my upcoming holiday. I had booked us a per-organized camping trip in France. We had four sites to go to over the sixteen day break. All site had fishing on site as although I love fishing, with a young family I rarely got the chance to go. My wife had suggested it and said when the kids were put down to sleep it would be a good time for me to wet a line or two. The kids were loving the holiday and I was enjoying the fishing. The holiday was almost half way through when we moved to our third site. We had seven nights there and on the first morning when we had arrived we needed to shop for food. So kids in tow we were going around a hypermarket when suddenly we were face to face with Liz and Jerry plus their kids. It turned out they had booked their holiday before she had joined our team. It just happened that they were on the sister site to ours just the other side of the road to us. Our site had the better facilities and they had been using them with their kids. My wife instantly invited them over for a barbecue that evening. This was their first week while it was our second week. Late that afternoon Liz, Jerry and kids came over and all the kids were soon in the kids swimming pool. They had a great time and then later back to our tent where I soon had the BBQ underway. The kids all had good appetites and got stuck in. Then I was cooking again for the adults. Jerry broke out the beers and my wife opened some wine. I wasn't sure how it happened but Liz ended up sat on my lap. I couldn't help the erection that slowly grew. It didn't help with Liz grinding her arse against it. Eventually all quite merry Liz and Jerry took their kids back to their tent on the other site. My kids were soon in bed fast asleep and I went off to drown a few maggots. I had barely set up when Liz appeared. She was still pretty tipsy and slurred, "Is that a gun in your pocket or are you glad to see me." Remembering her shuffling her arse on my cock earlier soon had my cock stirring. Liz joked, "You just can't keep a good man down," as she stroked her hand across the front of my trousers and my now hard cock. It was just seconds before Liz was bent over and hanging onto a tree as I got behind her and lifted her dress to find she was naked underneath it. My cock was soon out and in her pussy as I pounded away at her. It didn't last long before I emptied my balls deep in her pussy. The only thing I had for Liz to dry herself on was my fishing towel that I wiped my hands on. She wiped her dripping pussy and pulling her skirt back down and staggered away. I was left shell shocked at what happened and how quick it was. Later back at the tent my wife asked had I caught anything and my mind went to Liz. I told her I had one big one, just before I climbed on top and drove my cock deep into my wife. I couldn't get Liz out of my mind as I fucked my wife. I even heard my wife telling me, "steady tiger," as I rammed her pussy and drove my cum home in her pussy. The next day we had a visit to a nice town and market about ten miles away and then onto a beach where the kids played in the sea before we made our way back to the tent. After tea the kids were soon asleep and my wife told me to go fishing as she tidied up. It was earlier than when I normally got away and was pleased of the time. I was soon set up and fishing when Liz arrived. She was completely sober and I was about to apologize to her for my behavior the previous night when she ripped her dress up over her head and off. Apart from her shoes she was totally naked. I was soon sucking her tits and fingering her pussy as she struggled to undo my belt and pull my trousers down. Once down she dropped to her knees and started sucking my cock, something my wife doesn't enjoy. I couldn't allow her to suck me for too long as I was far to excited and close to coming. I had a ground sheet that I had put down where my kit was set up and the kit was soon discarded as Liz lay on it and I returned the favor and licked her pussy. Then I was on top and hammering away at her pussy for all I was worth. Liz wasn't that quiet and I was concerned that sound travels well across water and others would hear. Then with a final groan from both of us I emptied my balls for a second time in Liz's pussy. As I went to climb off there was clapping behind me and someone said, room for another. A man I had never seen before pushed me aside and thrust his cock straight into Liz's wet gooey pussy before anyone answered him. I heard Liz gasp, Oh yes." There was another man stood watching and wanking his cock as the first man banged away at Liz. She in turn just groaned and I could see her hip thrusting back at the mans cock that was plumbing her depths. As he finished and came in her his mate took his place and was soon groaning as he came in Liz. Her pussy looked a right mess with three loads of cum trickling from her stretched pussy. "Thanks mate, your wife's a good un," the first man said as he and his mate zipped up and walked away. I didn't have the chance to tell him that Liz was not my wife. Liz composed herself and using my towel wiped her fanny as dry as she could get it and then walked away in the direction of her tent. As I made my way back to our tent with with all my fishing kit I wondered what our final five nights might bring. The next night I again fucked Liz and as we sat talking afterwards I asked what Jerry thought she was doing. Liz informed me that since the birth of their last child, to get back in shape, she would take a long walk most evenings and that is where Jerry thought she was. She laughed that sexercise would probably be better to help her get back in shape. Shortly she went off for a short walk before returning to her tent. The following two night saw the two men return and claim their turns with Liz's pussy after I had my fill. My towel was beginning to smell and I had to wash it out. The penultimate night just one of the two original men returned, but in tow he had two other men. One was French the other Dutch. After I had my fill of Liz's pussy, the returning man had his turn followed by the French man and them the Dutch man. Liz seemed to love every second of it and moaned constantly as one by one the four of us fucked her. Our final evening Liz, Jerry and her kids spent the evening and a meal with us. Then as they went back to their tent my kids went off to bed. I again collected my fishing kit and made my way to the lake. To my amazement there was five men stood waiting for Liz. She didn't disappoint and soon turned up. The five watched as I took a long slow go at her pussy as it was certainly my last time to fuck her in France. Then one by one the five took their turns with her. Liz was talking to them telling them to fuck her harder and deeper. Most obliged, but I guessed that several of them did not speak English so just fucked at their own pace and in their own way. It didn't stop Liz groaning and giving orders. Then when all five had finished Liz cleaned up with my towel again and then rearranged her clothes and sat talking with me as the men disappeared presumably to their tents. As we talked I resumed fishing. About an hour later my wife joined us and sat watching as I fished. I caught a very colourful fish and my wife picked up my towel and went to hand it to me. She declared that it was slimy and smelly. I told her I had caught a few eels. She knew how slimy eels are so accepted my reasoning, but told me to throw it away before we traveled the following day. Then she hurried back to our kids that were fast asleep. Being our last night I had a good grope and kiss and suck with Liz's tits and then a final fuck. Liz went off to her tent as I cleared up and set off back to my tent. My wife was still awake and as I tried my luck. She complained that I smelt of fish. As I had only caught the one I knew what she was smelling was Liz on me. I was in luck and had a long slow fuck. I spent my time thinking about Liz as I plunged in and out of my wife. She enjoyed it from her moaning and we lay kissing and cuddling afterwards. The next day Liz, Jerry and her kids came to wave us off and said she would see me again in just over a weeks time on their return home. Back home I couldn't get Liz out of my mind. Then she was back and after welcoming her home and back to work, she informed me that she was working with me. I later heard that she had engineered our pairing by swapping with Matthew telling him she wanted more experience with what I was working on that day. In the van she told me about the rest of their holiday at that site. She said she had anywhere from three up to seven men on one night taking advantage of her pussy. Later that day on our way to the depot we stopped off at my house knowing that nobody would be there. I had barely shut the front door when she was bent over and kneeling on the stairs as I slammed her pussy good and hard. All the rest of that week we found time for me to fuck her and fill her pussy. The next few weeks she was paired up with Rob. I'm pretty sure that he gave her a good seeing to. Then she had a week and a bit with Keith and then she was back with me. We rushed through our work so that we had time to fuck. When we got to my house and I was slamming away at her pussy she suddenly gasped that she was pregnant. Fortunately I was past the point of no return and came deep in her pussy. As we recovered I confirmed that she had said that she was pregnant. I didn't want to ask who's it was in case she said it was mine. I was relieved when she said she had no idea who's it was. Then she really shocked me saying that none of her children were Jerry's. She added that he had no idea and thought that they were naturally his. She said he would accept this one as well, and she had no intention of disillusioning him. I felt a little guilty knowing there was a chance however slim that it could be mine, but agreed to keep her secret. I did fuck her a few more times but she was mostly paired with others. Then she was off having the baby. Six months later she was back and I was pretty sure she was still fucking around. I took a promotion and moved out of that team, but still saw her around from time to time. It was quiet a while later when I saw her again and there was no hiding the fact that she was pregnant yet again. I joked with her, "Who's is it this time?" She just shrugged her shoulders and then said, "Jerry's of course." I took yet another promotion and moved to another office and I saw her just one last time. She was just weeks before she was due to have the baby and asked if I wanted one last fuck. I must admit there is something really sexy about fucking a pregnant woman. More so if the woman isn't your wife. I had one final fuck with her making sure my cum was deep in her pussy I never saw Liz again but heard that after her sixth child she was sterilized. To this day I often wonder how many if any of the children were poor old Jerry's. I wonder if he would have been such a good dad to the kids if he knew their real parentage. Guess I will never know.
