I was happy. My girlfriend and me were dating for over a year, and so we 
decided to get married. 
There was only one thing bothering me, quite much indeed, and that was 
my mother-in-law to be. She was a career woman, smart, but most
of all beautiful and sexy, who sometimes flirted with me, which made
me feel uncomfortable.
One day she called me and asked me to come over to check the wedding
invitations. So I went. She was alone, and when I arrived, she whispered 
to me, that soon I was to be married, and she had feelingsand desires for 
me that she couldn't overcome. So before I got married and committed my life 
to her daughter, she wanted to make love to me just once.

What could I say? I was in total shock, and couldn't say a word.

So, she said, I'll go to the bedroom, and if you are up for it, just
come and get me. I just watched her delicious behind as she went up
the stairs. I stood there for a moment, and then turned around and
went to the front door. I opened it, and stepped out of the house.

Her husband was standing outside, and with tears in his eyes, hugged
me and said, we are very happy and pleased, you have passed our
little test. We couldn't have asked for a better man for our daughter.
Welcome to the family.

Moral of the story:
Always keep your condoms in your car.
