Sister Wife.

My wife and I are in our mid 20s and have been married for 6 years with 2 kids. A year ago, we took in my wife's little sister (19) and her 1 year old after her hubby went to prison. We have a small 2BR house and it was difficult at first, Wife and I had our room and we packed the kids into the other bedroom.

Sister-in-law was sleeping on the couch for about 3 months. After a while, the closeness of the arrangement presented an opportunity of even more closeness. The occasional nude or near nude encounters in the bathroom or bedroom went from being an "Oops" moment with giggling to just being a regular thing.

Sis had a great little body and the fact that she had a reputation of being a little firecracker made things that much more interesting. Unknown to me was the fact that the two sisters had been discussing little sister wanting to" get off the couch " ( as they explained it to me ).

I was all-in right from the start, off we went furniture shopping and bought a king sized bed big enough for 3. It wasn't more than 2-3 nights before the two of them started snuggling with me and giggling like schoolgirls. Seems my wife had decided to share me with her horny baby sister who had no man.

Now it's a regular thing for me to fuck them both, It's like I'm living a dream and we just found out, little Sis is pregnant. So I guess I'm gonna be an "Uncle-Daddy" ?
