Bill was quite happy. Bill and his girlfriend had been dating for over a year, and so they decided to get married. His parents helped them in every way, his friends encouraged him, and his girlfriend? She was a dream! There was only one thing bothering him, very much indeed, and that one thing was her younger sister. His prospective sister-in-law was twenty years of age, wore tight mini skirts and low cut blouses. She would regularly bend down when near me and Bill got many a pleasant view of her underwear. It had to be deliberate. She never did it when she was near anyone else. One day her little sister called and asked Bill to come over to check the wedding invitations. She was alone when Bill arrived. She whispered to him that soon he was to be married, and she had feelings and desires for him that she couldn't overcome and didn't really want to overcome. She told him that she wanted to make love to me just once before he got married and committed his life to her sister. Bill 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." Bill was stunned. He was frozen in shock as he watched her go up the stairs. When she reached the top she pulled down her panties and threw them down the stairs at Bill. He stood there for a moment, then turned and went straight to the front door. Bill opened the door and stepped out of the house. He walked straight towards his car. Bill's future father-in-law was standing outside. With tears in his eyes he hugged Bill and said, "We are very happy that you have passed our little test. We couldn't ask for a better man for our daughter. Welcome to the family!"

The moral of this story is:

"Always keep your condoms in your car."
