Riding my brother

I'm Geraldine 46 divorced 2 grown children, married at 16 and pregnant. I divorced 3 years ago and my children live and work on the other coast and rarely visit. I have a brother my only sibling and with both parents now passed on is my only close family member besides my children. David 44 divorced 5 years ago and also has 2 children who prefer their mother to him. David is a self made man and is still very well off even after the divorce and wasn't in the market as they say for another wife. She tries every now and then get more from him, but as she was the unfaithful one in the marriage, it has made it harder for her to get more out of him. Mainly as he offered her a large lump sum during and on her acceptance. The agreement bans her from getting more, without first paying back the previous amount. Which she has already spent, so she tries time and again and has so far failed. With his children backing their mother over him, he has stop all contact with them. Last year he sold his business and home and moved to a property in a rural area in a new state. Cancelling his email, internet accounts and cellphone. Getting a new cellphone and starting anew on his property, give me his new number only. He told me that he had enough of his ex wife attempts to get more money from him. I lost my job shortly after he had moved and decide for a change myself and moved to stay with David until I settled in. I also changed my surname back to my maiden name and got a new cellphone number and my internet was linked to my ex husband my access was all closed after the divorce. Only my children know my address and have been told to anyone, especially their cousins or ex aunt. While staying with David I noticed he had a really big cock on him while soaking in a hot tub together. He was wearing boxer type shorts and when they were wet, they clung close to his skin. Highlighting his assets you could say, that caused me to get a little horny myself. Not having sex for while myself then, I decided to asked if he would show me his cock, at first he wasn't going too. But I kept asking and I think he gave in to shut me up. I liked what I saw and started to play with his cock and went hard and was poking at me. So I started to stroke it more and told him I would get him off. He let me continue and ended up fucking and after he said we shouldn't have done it. I replied didn't you enjoy it, I did a great deal. He said he had also enjoy the sex, but he said it was wrong for a brother and sister to fuck each other. I responded that only if you have children together and I'm passed that now. He agreed that was the main reason and we left at that. That evening after dinner I asked him could sleep with him that night. At first he was against it, but I talked round and we slept together that night and every night since, but I have to start any sexual relations we have and I do that at least twice a week. I really like riding his cock.
