Carer to wife

I (27) was hired to care for a cripple, that is what his mother called him. He was 30 and in a wheelchair after a skiing accident. His mother hired me to care for him so she could continue with her social life unimpeded by her son. The family was wealthy, and I was to keep him company mostly and assist him when required. AS long as it kept him from imposing on his family's social life, they would be happy. Due to the back injury, he got slammed back-first into a tree he couldn't use his legs. Everything else worked perfectly. I lived in the cottage beside the family home on the estate with their son. It had been moved there after his accident to keep him away from visitors. I'm plain-looking, but have a large bust, and when I wore a low-cut dress, he got aroused. So, it became my job to get him off, moving on to full sex. For our mutual enjoyment, of course, despite our precautions, I got pregnant. After giving him a healthy son, the mother, fearing a scandal, had us marry ASAP. A quiet family-only event. We were both happy with our actions and quite happy to continue without marrying. But we didn't try to block her from arranging our marriage either. Our son is almost two now, and I'm again pregnant with a daughter this time. His extended family has accepted me as part of the family. His mother is not as much, but as I look after her son very well, she tolerates me, I believe.
