My little brother update

I'm Jane and last my little brother David came to live with me while he attended the local university. I came home late one night and walked in on him in the shower and caught him masturbating his huge cock. I ended up fucking him that night and regularly since then. Also, David is fucking our mother Karen after she came for a visit and found out from David about us fucking. I took David with me to my legal firm's new year's party and later had sex with David and I had forgotten my contraceptive pills and got pregnant to David. At first, I was unsure about what I should do and after tests were all good. I decided to have the baby and our baby girl Karen after our mother was born in September. Only the three of us know that David is the father. My father had a stroke in May and another in June and passed away. Karen has come to live with David and me and takes care of little Karen while I'm at work.
