Fidelity

My wonderful girlfriend and I had been dating for over a year, and so we decided to get married. There was only one little thing bothering me. It was her beautiful younger sister.
My prospective sister-in-law was twenty-two, wore very tight mini-skirts, and generally went bra less. One day "little" sister called and asked me to come over to check the wedding invitations. She was alone when I arrived, and she whispered to me that she had some feelings and desire for me that she couldn't overcome.
She told me that she wanted to make love to me, 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 upstairs to my bedroom, and if you want one last wild fling, just come up and get me."
I was stunned , as I watched her go up the stairs. When she reached the top she pulled off her panties and threw them down at me. I stood there for a moment, then turned and raced to the front door. I opened the door, and headed straight towards my car.
Lo and behold, my entire future family was standing outside! And they were all clapping!!!
With tears in his eyes, my future father-in-law hugged me and said, "we are very happy that you have passed our little test, and we couldn't ask for a better man for our daughter. Welcome to the family."

And the moral of this story is: Always keep your condoms in your car........
