Hello. I am a 29 year old guy. I have to get something off my chest. Last summer I went to visit my sister who lives an hour and a half away. She is married and is seven months pregnant. I got there mid afternoon. Her husband works as a truck driver and is gone for days at a time. So anyway
we get to talk about how its going just shooting the shit. I asked her how the pregnancy is going. She say ok I guess.
I say whats wrong
she says she needs to ask me something
she asked if when my wife was pregnant did I want to have sex with her.
I kinda laughed and said why doug doesn't want to have sex
she say he thinks its not right to because of the baby
so she tells me they haven't had any since they found out
Thats crazy I wanted my wife even more
I said. I didn't tell her but it made me horny as fuck when my wife was pregnant. So my sister says she has hormones like crazy and wants sex. So I tell her to talk to doug and that was that

Half hour later we decided to go for a swim before dinner.
so we go in and change. I come out and get in the pool
5minutes later she comes out and gets in. I was shocked she was having her first kid and her tits were huge. And she had a great ass. At this point my cock kinda gets semi hard.
well when she came up after swimming under water one of her boobs fell out of her bikini top. I saw the hole thing. I went rock hard. She laughs kind For shocked and say damn I dont fit in this top any more
the next 30 minutes or so we just swim around and go to get changed to get ready for dinner. She goes up the stairs and my dick goes hard again because of her ass. She looks at me as I don't make my way out of the pool
you coming
I said yeah in a bit.
she goes in and a get out and grab a towel. Still rock hard I go in the house and in to the spare room to change. She comes in the room like 30 seconds after and goes
I made you hard!
I go not that hard
and she was still in bikini
so I was still solid
she grabs my cock and goes bull shit
then her eyes go wide and shes like
holy fuck your stiff as fuck
im said so your sexy pregnant
without warning she pulls down my trunks and starts to jerk me off
I told her she better stop but she didnt listen. She pulls her bottoms off and says im soaking wet pushes me aside and says
you have to fuck me if nothing else just once she gets on the bed and tells me to fuck her from behind so we don't have to see each other and then it wont be weird. I couldn't help myself. She was so rwady for it I just slipped right in. She screams
OH MY GOD! Your are so deep and hard
I can't believe how wet she was
she begs me to fuck her and she hasn't had an orgasm from a cock in months
I just kept fucking her until I was about to cum. I told her when I was going to blow.
she's like dont stop what ever you do
its not like I can get pregnant
I pumped her as hard as I could
that pregnant girl screamed and came all over my cock I put the biggest load in her ive ever had.

we fucked once more that night so she can ride mu cock. When I got home my wife and I fucked all night.
a month and a half later doug wanted some one to stay with herbecause he was going to be gone for a week. I took vacation time and stayed with my sister. My wife stayed with our kid at home for school.
Needless to say

in three days I fucked her 10 times and she went into Labour the 4th day
we never had sex after that
but she told us last weekend shes pregnant
