 My Wife Has Sex With Her Brother-In-Law

   Last summer my wife and I were visiting her sister and husband.  Our
first day there we all decided to go swimming, for it was a hot summer
evening.  While in the pool I noticed that my brother-in-law was paying a
lot of attention to my wife.

   My wife came over to me and said that in the pool he was brushing up
against her, and she didn't know how to handled that.  I told her, "No
problem.  Just see how far he will go." (I had already told her several
times that I thought it would be cool for her to have sex with some other
guy, and that I would not be mad if she did.)

   She was a little nervous, but she went back into the pool.  Soon he was
again next to her, and he slowly became braver.  I learned later that he
actually started to rub his stiff cock against her ass.

   She told me she didn't resist.  Then he asked her if she was enjoying
herself.  She told him yes, but that she was "getting excited," and didn't
want her sister to know what he was doing to her.  He told her that he
would be discrete.  Then as he stood close to her and they talked, under
water he started to put his finger under her bathing suit, and proceeded to
penetrate her hot pussy.

   At that time my wife had never been with any guy but me.  She is a very
sexy women who juices up very quickly.  After letting him finger her for a
while, she pushed his hand away.  She came and told me that he had gotten
her quite steamy, and she was going into the house to shower off.

   I keep my sister-in-law busy on their patio, helping her fix a patio
chair.  I soon noticed that her husband went into the house.  I excused
myself, saying that I needed to see if my wife was OK.  When I got to the
bathroom, the door was slightly ajar.  I could see that the shower door was
all steamed up.

   As I opened the bathroom door a little more, I could see my wife and my
brother-in-law were in the shower together.  She was bent forward a bit,
and he was behind her.  I could tell that he was trying hard to get his big
cock between her legs.  She pushed the shower door open, and they both saw
me there.  Nothing was said.

   Since I could tell my wife was not objecting to what her brother-in-law
was doing, I just smiled at her, backed away, and left the bathroom.  She
told me later that when I left he continued pressing his cock between her
legs, and she felt it slide into her pussy.

   That night as she and I lay cuddled in our bed, she told me that once
his cock was inside her, he grabbed her hips and began a series of thrusts.
She said he really filled her full.  She kissed me and said she was sorry
for letting him do that, but that it really had felt very good.

   After I assured her that all was OK with me, she hugged me tight and
went on with her report.  It seems that she had a couple very enjoyable
orgasms before he finally let go and sprayed her insides as he climaxed. 
By the time she finished her report I was connected with her, and we had
some really hot sex.  I don't know if her sister and husband heard us.  We
were rather loud.

   The next morning I woke up and found that my wife was still asleep, so I
slipped out of the room to the kitchen and asked my sister-in-law if I
could help getting breakfast together.  After a little while I told her I
was going to wake up my wife.  As I opened the door I found that my
brother-in-law was there in the bedroom.  He had pulled back the bed
covering.  My wife's nightie up past her waist.

   I walked in and closed the door.  My wife started to protest that he was
messing with her.  And though I could see she was hot, she seemed afraid to
go any further.

   I told him to get onto the bed.  My wife looked at me strangely, but I
told her it was OK.  As he lay against her back I grabbed his long cock,
lifted and spread her legs, and guided his prick into her juicy box.  I
just said, "Have fun."

   Turning to see him humping my wife, I slipped out of the room and closed
the door.  I was so turned-on that I went into the kitchen and proceeded to
put my arms around my wife's sister...  cupping and feeling her breasts. 
She acted like that was a natural thing, but didn't respond, so nothing
happened with her.

   Since that day, her husband had made several business trips to our city,
and has stayed with us.  At the time I was working the graveyard shift.  My
wife told me that he would always come into our bedroom after I left for
work, and they became very close lovers for several years.  She would
always tell me all that happened.

   One night when he was at our house and I was home, I invited him into
our king size bed.  I lay there with them as he screwed my wife.  He wore a
condom, and when he pulled out, I was amazed at the amount of fluid that
was in that rubber.

   My wife was always happy to have him be our overnight guest.  I always
got a kick out of it too.  Her reports about the things she did with her
brother-in-law always made for great sex for us later.
