A girl and her mother were walking through the park and the little girl saw a man and a women kissing. The little girl asked, "Mommy, what are they doing?" The mother replied, "Baking a cake". Later that day, the girl and her mother were at the movies. A small sex scene came on. The little girl asked, "Mommy, what are they doing?" Again the mother replied, "Baking a cake". The next morning the little girl told her mother, "Mommy, you and daddy were baking a cake yesterday, weren't you?" The mother asked the girl, "How did you know?" And the little girl replied, "Because I just licked the icing off the couch."

Later, QD.
