When she answered the door I was totally surprised: she had her hair in pig tails, the sweater she wore when she, and my daughter, were cheer leaders... and a short skirt that barely covered her ass.I looked at her,and said, "Oh, my.....daddy's little girl is beautiful!!" "Do you like me, daddy?" I wasn't sure of what I should say, but I finally blurted out, "Sweety, you are the most beautiful girl in the world. Daddy loves you so much."She came over and but her arms around me. "Daddy, I have. The week went by fast. Ellen and I were really looking forward to the week end and the house around the tree.
