My sister lives with her girlfriend or maybe I should lover her. Se she is into females only and as far as I know I am the only guy to have his cock inside but that was a few years ago when we were drunk and she wasn’t sure yet.
Her girlfriend is not to bad looking and to me its a waste of good pussy but that’s just me.
My sister dropped by and said she needed a favor from me saying she knew it would be asking a lot but hoped I would help her and her mate out. I said as a joke what you want to have kids and you want me to jack off in a cup for you. She seemed a little embarrassed but said no we would like it if you could fuck Karen and get her pregnant.
Now that was a shock but she said they don’t think in this state that same sex marriages are legal so being single in their eyes the sperm bank wont help us and Karen has ever been with a man so we were hoping you could help us. All I said was you wouldn’t be knocking on my door a year from now saying I have to pay child support right? She said no, why would we do that, it would be our child you would only give your cum that’s it. Well what the hell, after all Karen is sexy little thing and I get my rocks off for free.
At first it was get myself, Karen would use some lube and just stick it in and fuck. After 2 months I told my sister this isn’t going to work if I cant get her in the mood, so I said you stay home and just let me see if I could get her ready without the fucking lube. My sister didn’t like it but agreed.
I had a candle lite dinner with wine and the whole bit and warmed her up for a good two hours before we went two bed and Karen turned into a fucking wild cat in bed. That was Friday night and we stayed in bed for most of the weekend fucking like rabbits. By Sunday Karen told me she thinks she is in love with me and didn’t want to go back to my sister.
Three weeks later Karen missed her period and found out she is pregnant and came to me telling me she wanted her child to have a father not two mothers and I agreed so the next weekend she came to my place but we did a quick trip to Vegas and got married. Now my sister says if she ever sees me again she will cut my balls off but it seems to me I did her a favor by finding out Karen is more straight then bi. Or maybe I just like the idea of stealing her girlfriend. I guess it could be both.
