My wife and I separated two years ago, when my stepdaughter Amy (18 years old )was young smart girl , but it was still my habit to go by the house and check on her every Saturday morning, just to satisfy myself that she was handling things all right. She was a 16 year old teenager when I started seeing her mother regularly, so the separation meant losing daily contact with the only father she had ever known. This particular Saturday I decided to ride my bike over. I noticed that her mother's car was not in the driveway as I rolled my bike down the walkway behind the front hedge. Leaning the bike against the wall of the house, I gave a quick "shave-and-a-haircut" knock on the front door. The door opened almost immediately, and I entered to a huge hug from my stepdaughter. I was acutely aware that she wasn't wearing a bra, both because off the soft pressure of her round nubile breasts against me and the feel of her firm back under my hands. I stepped back to look at her and saw that she was wearing one of my old khaki, long-sleeved army shirts and a pair of white cotton panties. Only the top two buttons of the shirt were fastened, so I had an unobstructed view of her smooth, white tummy and long legs. Considering that she was now older and beautiful, this could hardly be an accident. I must pause to explain that my stepdaughter is still very beautiful, but at this age she was just exquisite. 5' 7", slender, with beautiful, proud, breasts, gorgeous auburn hair, and alabaster skin. I had a dim suspicion that I was seeing something that I hadn't seen before.
