Derided

Growing up I was derider by my only sibling as nerd/geek and complete loser. My party going sister failed to into university and ended up working low paid jobs and then marrying a low life loser (her description). I had done very well at university and got a very good paying job. To get me to sign on they paid my university fees and gave a 4bedroom 2baths house. In the years since leaving university, my life keeps improving. Not so for my younger sister who marriage ended suddenly when her husband tried robbing a liquor store and got shot by the owner. Not widowed and soon to be homeless, luckily no children. She had two choices live with me or our parents, our parents lived in a small town and my sister didn't want to return there so I was her choice. She had heard I was doing very well and was still shocked by how well I was doing. But she had to be careful, as any smartass remarks might get her kicked out. I'd a boring lifestyle compared to hers, but I was well setup, and she was almost in the gutter. Anyway, we got on fairly well, her working spot jobs for money and looking for something better. She avoided dating and I didn't date, so when my invitation to the company's award night came. She took notice, the gold embossed invitation would allow me and my partner to enter. I'd no partner, nor very interested in attending either. My sister saw it as a chance to enjoy herself albeit with me, but I said I would take her just to stop her asking me. It cost me money of course because she needed clothes and hair done and she couldn't afford any of that. But she looked gorgeous on the night, I was quite proud to have her on my arm. Nobody knew she was my sister as the name tags had different surnames. The company is very large and different departments, so name tags were required. She had to stay with me, because she was out of her depth, as most was work talk. The wives of others were also very snobbish in my sister's view. Not that they put her down, more that she thought herself not as good as them. Anyway, after getting home she wanted something more and that was sex and me being the only male available she straight out asked me to fuck her. I was talked into sex with her (fairly easily), and I was awkward and so she decided to train me to do better. She hasn't left my bed since night, even those she says I'm a good lover now. There was one more change, she changed surname back to her maiden name before the next company's awards night. Now marked as my wife by others there, even without wedding rings. She was and is quite happy with her new life with me, our father's death got our mother to move and live with us. It was her who suggested we have children as she wanted grandchildren, and I wasn't likely to find a girl marry and start a family. My sister was onto a good thing in her mind, better life than she would've if she left. My sister thought it over and agreed, my approval wasn't required. Now 7 years later and 3 children all healthy and very happy mother and a sister/wife. She derided me when growing up and now is my lover/wife.
