This happened a few years back while my sister-in-law was living with my wife and I. Understand, my wife will bring a raging hard on in a second... but Deanna, her sexy sister, was about 19 years old at the time and had the nicest body with great tits and a firm teenage ass. I fantasized many times about the 3 of us mixing it up. Anyway, she had been living with us for about a year when she "caught me in the act".
You see, I have always enjoyed masturbating ever since a friend "showed me something cool" in grade school.
Deanna was perfect spanking material with that knock out body of hers.
I would often be whacking away in the bathroom as I watched her lay out
by the pool and spread sun tan oil all over that lucious body.
Occasionally, when she thought no one else was home, she would even
take her top off and expose those lucious tits. One time, when I came
home for lunch unannounced, I was watching her from our bedroom which
happened to overlook the pool. Fortunately, my wife wasn't home and I
decided it would be a great time to "release some tension". So I layed
on the bed and started pounding. I would watch her and fantasize about
rubbing oil on her tits and ass. After I got into it for a while, I
closed my eyes and was just wanking harder and faster than ever. The
next thing I knew, the door opened and Deanna walked in!!! She must
have thought I was her sister. I don't know who was more embarrassed.
She quickly shut the door and said "sorry". At that point, I figured
what the hell.... I was already busted.... might as well finish up.
However, I just couldn't seem to get back into it. So I got dressed and
walked back out. When I walked by her room I was still so embarrased
that I didn't even look inside. After I passed by her door and was
heading down the stairs I heard her say "come her". So I went back up
the stairs thinking she probably wanted to apologize for walking in on
me. When I got to the door I got an insta-boner. She was laying naked
on her bed!!! She told me not to worry that it would be out "little
secret". I don't think I heard a word she said.... I was too busy
planning my next wanking session just picturing her laying on the bed.
Then she really blew my mind. She said she would like to watch me
masturbate for her sometime. She said she masturbated frequently. My
cock grew harder and harder picturing that. I told her I would love to
if she would do it for me. She got a big grin on her face and said...
"come on in and lock the door". Without all the details (which would
take 10 pages to describe) we spent the next 45 minutes pleasuring
ourselves and each other. We did everything but have sex... I mean
everything. She finished me off with a blow job and hand job not to be
beaten (no pun intended). When we both finished up, she gave me a long
wet kiss. She moved out shortly thereafter and we have never done
anything like that again. To this day it is our "little secret" and we
just smile and wink at each other when we get together to remind us
both of how great it was. I have wanked to that experience many times
since and would like to hear any stories about other guys sister-in-law
or mother-in-law experiences.
