Knocked Up

All names changed.
I was between boyfriends and feeling horny and walked in on my younger brother in the bathroom. He was finishing drying himself and I saw his large cock hanging between his legs. Never been a backward type of person, I asked him to fuck me. He was at first a little shocked, but I knew seeing his cock getting hard he was willing. Not wanting to risk getting pregnant I had him use a condom I carried in my bag. He put it on, and we had sex and from then on it was fairly regular for us to fuck. One of the condoms burst during sex and he came inside me. I wasn't concerned and we continued fucking, then I missed a period and then another, so I got tested and confirmed as pregnant. More test followed and nothing bad was found and so I had the baby girl now 3 and I'm again pregnant to my brother. We're living together and are happy with our little girl, our mother loves her also and now lives with us. Our father departed years ago and hasn't stayed in touch.
