My brother David

I'm Caroline 35 divorced and no children, after my divorce was final in November. I got and job in the next state away from my ex. Lucky my younger brother and only sibling lived there, so I could stay with him till I found my own place. David 32 single a quiet shy person and had been all his life. Our late father believed it was because our mother died when he was 4 and it affected him greatly. David was paying off his own house and went to work and back home nothing else. His house was 3 bedroom 1 bath ranch style and except for his dog called Brutus he was alone. I moved in the weekend before starting my new job and the first weeks I stayed at home every night until I made some friends at my new job. David never went out except to work or a quick shopping trip. Then I walked in David on a Sunday morning after being out late the night before with some women from work. Catching David cock in hand masturbating himself, it didn't shock me that he masturbated. But the size of his enlarged cock did, it must have been at least 12 or so inches long and quite thick as well. It was a monster and after saying sorry and then returning to my own room, I had to masturbate myself. David had been shocked at getting caught, but didn't say anything and so that was how I started to fantasize about being fucked by David. Over the following days I couldn't get his huge cock out of my mind. Then about 2 weeks later I walked in on him again, he was just getting into the shower and I don't what came over me. But I couldn't help myself and stripped naked and joined him in the shower. This shocked David and I started washing his body and then stroking his cock. Which grew bigger as I stroked it, after it was rock hard I went down on him and sucked him off for a while before getting him to mount me. After fucking in the shower I told him he could fuck me anytime he wanted. Still I had to initiate the sex sessions between us. Over the following month I started sleeping every night with David and we still sleep together now. Early last month I got a divorced friend Diana 29 from work to join us camping and we had threesome with David and Diana has since moved in with us. We are all enjoying relationship and I've tested positive to being Pregnant and couldn't happier. Diana has stopped taking her pill now also and wants a baby as well.
