My Sister

I 29 was living in another City when both my parents suddenly died in a car accident. My sister 24 has a disability not able to walk without a walking frame. As her only sibling I thought my duty to take her in to live with me. She is very smart and works from home via the internet and was soon doing all my computer work for my business as well as her own business online. I run a mobile mechanic business and am doing quite well, I'd a girlfriend at the time. But we weren't getting on well at the time and soon parted, mainly due to my working odd hours as she called them. But I work when I'm needed and that's what make my business perform better. Being reliable, means I get return business and referred to others. So, not dating and living with my sister, the usual story she caught me masturbating myself and asked could she watch. She started playing herself and one thing led to another, and we became lovers. Of course, we would stuff up and had a daughter perfectly healthy (2022), so my sister is now pregnant again. As far as anybody else knows we're married, we are quite happy with our relationship and plan to have four children in all.
