For as long as I could remember my parents fostered other children. They were generally older than my sister and I, and I often felt that we came second to them. They tended to come and go fairly frequently. I remember that I had just turned eighteen when they had a baby for a few days until it went to a couple that was going to adopt it. The couple turned up with a social worker. The woman was a lot younger looking than her husband. I heard her speaking to my mother that her husband had been trying for over four years to get her pregnant and it just wasn't happening. I thought to myself that I wouldn't have minded getting her pregnant. She was sexy with an almost sweet looking face. I helped take all the babies things out to their car as Jean fastened the baby into the seat. Then as I put the last piece in the car Jean put her hand on my arm and it stayed there far longer than it needed to. Then jean climbed into the driving seat explaining that Glen doesn't drive. I laughed to myself that it wasn't the only thing that he couldn't do. Then they drove off. I thought that was that so to speak. A few days later driving to my mates house I spotted her car. It turned out that she lived just five roads from us. The following day my mother was talking to someone on the phone when I arrived home and after she put the phone down she informed me that it was Jean and that she had bought a cot for the baby but as hard as he tried Glen wasn't able to put it together. I again laughed to myself that it wasn't the only thing he couldn't get together. Then my mother informed me that she had offered my services to put it together for her. I drove round expecting to see Glen there with bits of cot everywhere. To my surprise although the cot parts were spread out there was no Glen. Jean informed me he was at work and the baby was sleeping for once. I had already noticed that the blouse that Jean was wearing was tight showing of her tits and she had on a short skirt that almost showed her arse when she walked into the bedroom in front of me. I took one look at the plans and could see how it assembled. Jean was joking that she had bought some Ikea furniture a few years back and Glen couldn't put those together either. I started the assembly but it required extra hands at various stages. Jean helped holding parts while I screwed them together with the Allen keys and screw drivers that came with it. It wasn't long before I had the four sides together having worked out how the drop side worked. All was left to do was drop in the base and do the screws up and then insert the mattress. the eight screws for the base did up from underneath so I lay on my back and shimmied under the cot and did the first two up. I wriggled down a bit further and did the next two up. I was about to wriggle out when jean handed me two more screws. As she did I could see right up her skirt to her panties. I could feel my cock waking. I tried to concentrate on the job of assembling the cot and did those two up and as I wriggled down level for the last two screws jean again handed them to me. This time she had squatted down and I had an even better view of the bulge of her pussy lips in her tight panties. I could also see clearly that there was a damp spot where her pussy hole would be. My cock was positively throbbing now as I fastened the last two screws. As I wriggled out from under the cot Jean was straddled my body and I had a great view straight up her skirt and as I cleared the cot Jean stepped away. I was embarrassed by the tent that had formed in my trousers and could see that Jean was looking directly at it and then she licked her lips in a way that almost made me cum then and there. Jean broke her gaze and reached for the mattress and as she did I lowered the side for her. Jean bent forward to put the mattress in giving me yet another view of her panties. Then she went about fitting the mattress protector and the sheet, each time giving me an even better view of her panties and that wet spot that had grown considerably. As she bent forward I could contain myself no longer and reached forward and stroked her pussy through the tight material. Instead of standing and slapping me, which was what a married lady should do, she just groaned and wriggled her arse on my fingers. With no protest or resistance I pulled the flimsy material to one side and slipped one and then two fingers in her tight hole. I heard her groan yes and then groan even louder as she thrust her arse back onto my fingers. I had to free my cock as it was getting very uncomfortable in my trousers. Plus I had somewhere I wanted to introduce it to. Jean was groaning with every thrust of my fingers as I worked on freeing my cock. Once freed I lined up and removed my fingers with a moan from Joan that was soon replaced by the loudest groan as I thrust with my cock deep into her pussy. Now Jean was pushing back to accommodate my incoming cock as I thrust time and time again at her pussy. It wasn't long before Jean's pussy tightened around my cock and she was groaning as she came. I followed closely and dumped my load deep inside her tight pussy. It was only when Jean scuttled away with her hand on her fanny trying to prevent my cum from dropping onto the carpet did I remember that she was trying to get pregnant. When she returned from the bathroom I asked if everything was ok and was it ok that I came in her pussy. She said she was sure she couldn't get pregnant as they had been trying for so long and Glen had two kids by his first wife and therefore it was her problem and not his. After that day, once or twice a week I would go around and fuck Jean in just about every room of their house, never once taking precautions. This had been going on for almost four years when she called off our meeting quite unexpectedly. Instead we met in a coffee bar in town. I was concerned that Glen had perhaps found out about us. Instead what Jean told me shocked me even more. She was three months pregnant. Glen was over the moon as he thought it was his, but Jean suspected that the truth was more likely that the baby was mine. She wanted us to stop seeing each other. I decided that if we wanted to keep the baby's parentage a secret Jean was probably right that we should stop. I kept my distance and refrained from ringing her. Then two months later she called me. She said that Glen was scared of hurting the baby and would not fuck her hard enough for her to get off on it and needed me to go and do the business. Her adopted baby was at play school when I arrived and she was dressed in just a negligee. We never made it to the bedroom. I fucked her on the first few steps of the stairs from behind as she knelt there groaning loudly as I pounded her pussy. Then she was laid on the landing with me still stood on the stairs, banging away at her underused pussy. After my second load she rushed into the bathroom to empty her bladder and pussy and clean up. I wasn't ready to stop yet and had her yet again bent over the bath. That was some session. I continued to fuck Jean up until the day before she gave birth. Glen was over the moon at his baby girl and there was no way that Jean was about to spoil his bubble. It was some while before Jean was able to have sex again and as soon as she could I got the call to resume our affair. The first thing I asked Jean was did she need me to use condoms knowing that she was able to get pregnant after all. Jean said no it wasn't necessary. It was fourteen months before she was pregnant again and all through the pregnancy I fucked her on every opportunity that I could. A few months later I was back fucking her some more. Still unprotected. After the third time she was pregnant. Glen said he had been and had the chop. I banged Jean all through her pregnancy. Sadly after her third child was born Jean called a halt on our affair. For over ten years Jean and I kept apart. Then out of the blue I received a call from her asking could we meet. We met in a local cinema and after a bit of fondling she told me that Glen was unable to get an erection any more and she was desperate for a good shagging. We left the film and drove into the countryside where we fucked in the back seats of my car. I then had to rush her home to go collect her kids from schools. For the next two years we fucked whenever we could. Then the inevitable happened, Glen caught us. He walked in to find me fucking Jean on the kitchen table. He just walked past as if nothing was happening and upstairs to his bedroom. We finished fucking and dressed quickly waiting for the fallout. When he came back down stairs he sat at the table suggesting we all had a cup of tea. I was still expecting him to explode, but it never happened. As we sat sipping tea he calmly said that he knew the children that Jean had were mine. I was gob smacked. Then he calmly said that there was no way that they could be his as after his first wife had their second child he had a vasectomy and not after Jean's third child. All this time he had known that they were not his children yet he treated them as if they were. After that revelation I got bold and asked where we went from here. Glen said that he didn't want the kids to know that I was their father. Neither did I as I had already got a family of my own wife by then. I agreed as did Jean. Then he astounded us by saying that as long as we were discreet we could continue to see each other, but there was a condition. Either I had a vasectomy or I would have to use condoms. The timing couldn't have been better as my wife wanted to come off the pill and as neither of us wanted any more children, she wanted me to have the chop. It was three weeks later when I had the job done. I can tell you it was bloody sore and my balls felt like footballs between my legs. Three months later after the final all clear I was able to fuck both my wife and jean unhampered. That one time was the only time Glen ever saw us fucking although he knew we were still seeing each other. I was fifty seven when my wife informed me that she didn't want sex anymore and that if I did I would have to find someone else. Little did she know that I was already seeing Jean. I made no secret now that I was seeing someone and Jean suggested that if things were awkward I could bring her home as long as we only used the spare bedroom. She didn't want jean in her bed or for us to flaunt it in front of her. From then on Jean and I had two places where we we could see each other and we made good use of both places as often as we could. We even spent a few evenings out with Glen,Jean and my wife. There was nothing sexual about my wife and Glen as one couldn't make love and the other didn't want to. But friendships blossomed between the two family's. We continued our affair up until the virus put us in lockdown. We had still kept in contact by phone and last week was the first time that we actually met again in person. Tonight will be the first time in well over a year and a quarter that I will have had sex. As I write this I am waiting for Jean to arrive at my house for some fun.
