For the reader: The story is one of fiction and the characters are all above the age of consent. It is quite long, but popular request is that the original version broken into chapters made them too short so this is the full version with minor editing. I have tried to write it as realistically as possible but it should be treated as the fiction that it is, no more, no less. This is the first story that I have ever written so I do look forward to any comments or constructive criticism that you may have. A sequel is currently in the works and should be out in the near future. (K.S. - 11April2014)

I married my wife when my step-daughter was only four years old and have raised her ever since. As such, we have always been quite close, with her feeling comfortable either confiding in me or my teaching her life's little lessons. She has always been a smart girl for her age so as she grew up, I never needed to worry about her understanding of the changes to her physiology or the "birds and the bees" that my wife and I had taught her about but in other ways she could be quite innocent about the ways of the world. As she developed in her teenage years, this is what concerned me the most. She has matured into a very pretty young woman, standing about 5'6" with an average weight, straight sandy-blonde hair cut to her shoulder blades, and firm young breasts filling a B-cup nicely. Her birthday was in the fall, just after the age cut off for school admission and she was now a senior in high school and had recently turned 18 years old. I tried the best that I could to prepare her to make the right choices and not feel pressured by the typical teenage boy's libido; this was going to come back around...
Our family was pretty open about most things. My wife and I had taught the kids about responsible alcohol use, anatomy, and sex among other things starting at an early age and didn't believe in hiding information from them. We also had a pretty open household that respected privacy but wasn't overly modest; we didn't run around the house nude but it wasn't uncommon to see someone walk across the hall from bathroom to bedroom in their underwear or with only a towel wrapped around them. Likewise, lounging in pajamas or a nightshirt was normal, especially on our family's weekly "movie night."
Due to the closeness that we shared, it was fairly routine while she was growing up for the two of us to share physical contact: almost nightly hugs goodnight, taking care of her ailments (cuts, slivers, etc.), goofing around and tickling her, or curled up on the couch together while watching a movie...it was on one of these nights that things slowly started to change.
We were on the couch watching a movie, essentially spooned, with a blanket over us and her mom and brothers in the same room watching as well. As any of you who have ever lain down like this can attest to, most couches can be a little bit narrow for two adults to be like this without the one in front being right at the edge. We were no different and to keep from falling off, I had my arm over her across her torso and she was snuggled fairly close to me to help keep her on the couch. This night started out no differently than many others before it but none have seemed the same since.
About halfway through the movie, which had already had a few sensual scenes despite being PG-13, one scene gave her a mild startle causing her to back up into me a little further. I didn't even give it a second thought when she remained like that after the initial shock had subsided. A few moments later I felt an almost imperceptible movement of her hips grinding on me a little, but since I had never had any untoward thoughts about her before, assumed that it was just her trying to get more comfortable again. This fidgeting continued every now and then for the rest of the movie and the physical contact with my groin threatened to cause an erection but, since I assumed that this was completely innocent, it never became anything more than a slight swelling that I hoped had not been noticed. This had never happened before and I assumed, was completely innocent.
Over the next few weeks, everything remained normal between us except that similar contact was happening more routinely on movie nights and on one occasion she clutched my arm a little bit and after she relaxed I realized that my hand was actually in contact with the underside of one of her breasts. There was a part of me that felt as if I should talk to her about all of this but I ended up dismissing it thinking that it was still innocent. I didn't want to highlight the occurrences and make her think that I was some sort of lech lusting after her when she didn't even realize that it was happening (I assumed). As far as I knew, she was still an innocent girl in the ways of love.
This had been going on for a little over a month and was still easily written off as innocent when things started to heat up a little more. My mindset, however, still was focused on my step-daughter's innocence and dismissed even this new development.
