So, now the story. And keep away from the end until you reach it!

My wonderful girlfriend and I dated for over a year, and were so in love we
decided to get married. Only one little thing bothered me, though, it was
her beautiful younger sister.

My prospective sister-in-law was twenty-two, 5'6" 130 lbs., had a waist like
a hornet and wore very tight mini-skirts to show it. She had perfect 36C
breasts and generally went braless. She would regularly bend over when she
was near me, and I always got more than a pleasant view of her private
parts. I knew it had to be deliberate because she never did it when anyone
else was near.

One day "little" sister called and asked me to come over to check the
wedding invitations that had just been delivered. She was alone when I
arrived, and she whispered to me that she had feelings and desires for me
that she couldn't overcome. She told me that she wanted to make love to me
just once before I got married and committed my life to her sister.

Well, I was in total shock and couldn't say a word. She said, "I'm going up
to my bedroom, and if you want this, just come upstairs and get it." I was
stunned and frozen in shock as I watched her go up the stairs. When she
reached the top she turned around and sexily pulled off her thong and threw
it down the stairs at me. I stood there for a moment, then turned and made a
beeline for the front door. I bolted through and ran straight towards my
car.

Lo and behold, my entire future family was standing in the yard-all of them
clapping and laughing! With tears in his eyes, my fiancée's father hugged me
and said, "We are very happy that you have passed our little test ... we
couldn't ask for a more honest man for our daughter. Welcome to the family,
son."
