My girlfriend and I decided to get married.

One day her little sister called and asked me to come over. She whispered to me that soon I was to be married, and 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. I was in total shock and couldn't say a word.

She said, I'm going upstairs to my bedroom, and if you want to go ahead with it just come up and get me. I was stunned. I was frozen in shock as I watched her go up the stairs.

I stood there for a moment, then turned and went straight to the front door. I opened the door and walked straight towards my car.

My future father-in-law was standing outside. With tears in his eyes he hugged me and said, We are very happy that you have passed our test. We couldn't ask for a better man for our daughter. Welcome to the family.

Moral of the story:

Always keep your condoms in your car
