My Brother David

David 27 is a quiet person by nature and had a hard life as the youngest of 3, our mother died when he was 4. Our father neglected him leaving him in the care of a housekeeper who liked a drink. My other brother Andrew was 13 and away at school most of the time and didn't get affected my much. I'm Marion and was 9 at and raised by my grandparents mainly after the death of our mother and also missed what happened to David. When I was 22 and in university my grandparents passed away in an accident. So I moved back home to my father's place. I found a very quiet brother who wasn't outgoing in anyway kept to himself all the time. Not send away to school as my father thought him retarded, not that he had much if any interaction with David. The old housekeeper was gone, died due to over drinking years before. But the damage was done, I soon realized David wasn't retarded but reclusive and was very intelligent and worked on his own computer. The new housekeeper didn't interact with David, except to tell his meal was ready as David kept out of her way. A lesson he learnt from being with the old housekeeper I assume. I was able to live at home while going to university and when my laptop crashed on Sunday and it had all my work for the Monday on it. I was desperate to get it fixed, quiet David spoke to me without being spoken to first. He asked could he look at it for me, I said go ahead and he fixed it fairly quickly. Not only had he got it working he had speed it up as well. I kissed him on his forehead and thanked him, he became my go to guy for my computer and online problems. I finished university and married, but it didn't last. I had gotten my father to let David attend university, he still thought him retarded. But David done very well at his studies in computing and all other as well. This didn't impress my father as he then thought David a Savant or something similar. David finished university top in his class which still didn't impress our father who views on David were fixed. But then our father died a brain aneurysm leave me as guardian of David in his will, I wasn't concerned by being David's guardian. David Didn't work and an allowance from our father because he thought David was a retard. Andrew my other brother was happy he didn't get lumbered with David as he believed our father about David and hadn't be around David much and on his rare visits. David kept his distance from Andrew and they rarely spoke at all. That brings us up to date almost, I was now 31 divorced no children and looking for a another job as I had been working with my ex. David was 26 almost 27, we downsized as the family home was sold to split the money between the 3 of us. We were very off anyway, but Andrew thought David shouldn't get an equal share because he was retarded and implied he might try and change that part of the will. I stopped that by saying not smart brother, a judge might think because of David's disabilities, he might needed a bigger share to look after him in the future. That stopped Andrew in his tracks as he didn't want to risk it, as I would be supporting David as I was his guardian. With no need of a housekeeper, I bought a 4 bedroom house. a room each for me and David and a room for David's computing equipment and spare as well. During a thunder storm I couldn't sleep and didn't want to be alone so I joined David in his bed. I was awoken later by a loud thunderclap and looked at David it hadn't woken him. I moved closer to him, that's when I felt his hard cock. He had a hard-on and must have been dreaming of something sexual. To my surprise as I felt it very large, biggest I had ever felt. I needed to see it and managed to get it out of his shorts. Once I had it out, I started getting very wet and wanted to try it out. I hadn't had any sex since before my divorce, Thought I could remove my panties and bock on to his cock, but dismissed it. I decided to wake him and get him to actually fuck me, so I woke him. David wondered why I had woken him, I told him he was poking me in the back with his cock. He was shocked and said I'm sorry, I said you made me horny now as well and you can satisfy yourself and me and we can go back to sleep again. He was unsure, but I got him to fuck me and I really enjoyed him fucking me. He done everything I asked him to do and he came inside me and we cuddled together and fell back asleep. In the morning I was going for a shower and decided to have David join me and it was easy as he trust me and does everything I ask of him. Doing the shower he got another hard-on and we went back to his bed and I drained him. That day I moved all his things in to my room the master bedroom and we sleep together every night and I take care of his sexual needs. I'm also pregnant to him as not being sexually active since my divorce I hadn't been on anything to stop getting pregnant and on finding out I was pregnant I got tested and with everything okay. I told David he was to be a father. As for Andrew he thinks I had one night stand and got pregnant, because that's what I told him.
