My Virginity and how I lost it

I'm Daphne 35 have 4 children and live with my brother Paul 38 single father of my children all healthy. When I was almost 19 our parents both died in traffic accident. A large truck turning sharply rolled over onto their car crushing both of them. Paul was at university at the time and we were both left shocked and crushed by our loss. Only the following year we put our lives back together. We sold the family home and moved closer to the university to cut down travel time as we were both were go there then. We sold the home too many memories and focused hard on our studies. Paul Graduated with honors and got a great job straight away. As we never dated anyone and didn't mix much at all with other students, Paul and I went out to celebrate his great job. We weren't use to drinking and on getting home started mucking about ending up in bed together fucking. That was first sex for both of us, we could've stopped with one, but we didn't. I got pregnant and had our first child who was healthy and then I graduated myself, living with Paul and me wearing my mother's wedding rings everybody assumes we're married. Then another baby and then another and now we have four all healthy and I've started taking precautions as four seems the right number for us. My first fuck was with my brother Paul and I was also his first fuck.
