She didn't turn any lights on, but took my hand and led me through the lobby to the treatment area, closing the heavy door behind us. I heard her fumb...ing on the wall and then the click of a switch. I stared at her, awestruck. She was naked except for a heavy gold chain round her neck. Two finer chains ran down from it to her breasts, passing through slender golden hoops that had been inserted into her tiny nipples.

It seemed like I was masturbating every hour when I was off from work. My mind reeled with excitement. I knew I was being bold and daring, and I wondered what. I've lived more or less on my own since I was sixteen, half way through my third year in high school. I had lost my virginity when I was fourteen at a summertime beach party. That was unprotected sex and even then, I knew that I could not risk getting pregnant. When I told my mother what I had done, she cried but then made an appointment with her doctor for me. I had to promise her that I would never, ever let my father know because he was an extremely conservative and religious man and would. And untied the sash on her robe.I stood there, absolutely shocked, staring at an amazingly sexy pair of silky looking underwear and a lacy bra, barely covering the large teenage breasts that were squeezed into that bra.And I felt my dick growing hard at ten in the morning.Just then, without warning, Katie pulled the sash closed on her robe, and walked into the living room.I saw my step-daughter walk out of her bedroom, smile, wave, say, "Hi," and start walking down the hallway towards me.Katie.
