My father got me pregnant when I just turned 14. He went to jail and I had a son. When I was 29 and my son turned 15, I couldn't fight my desires any more and seduced him. Three years later on his 18th birthday I found my self pregnant by him. We decided to keep the child a girl and it 22 years and we are still together. Our daughter knows we are mother and son. Last year at 20, she asked to join us, and we agreed. We have oral sex threesome most night and fuck like mad on the weekends. She also wants a baby with her father. I get turned watching her ride her father and take his cum.
