The Moral Of The Story...

A newlywed man arrives home one day. As he ascends the stairs and enters the bedroom he sees his wife's sister sprawled on the bed completely naked.

"I've always had a thing for you since you started dating my sister", she says. "You can have me right now anyway you want me. I won't tell a soul."

The man immediately does an about face and goes down the stairs and out the front door. Outside waiting is his wife. She immediately walks up to him and embraces him.

"Honey I'm so proud of you!", the wife says. "You resisted temptation and now I know I can trust you the rest of my life."

The moral of the story? Always keep your condoms in your car.
