My wife Ann changed when our daughter became a teenager; I think she thought Jessica had become a rival to her. Ann became so dark and spiteful. Things came to a head when Ann became violent with Jess when the latter was fifteen. Ann tried to strike out at her daughter, but Jess's youthful reflexes enabled her to push her mother away.
Unfortunately 'away' was in the direction of a flight of stairs . . .
Ann survived, but from her hospital bed she set the police on Jessica. Jess was taken into custody and I first visited my daughter to comfort her, then to my lawyers and thirdly to the hospital to serve my wife with divorce papers, then back to Jess.
I did what I could for Jess, but I'm not a lawyer and I'm not rich; the court ended up sending her down for four years, to a young offenders' institution. I visited regularly and she seemed to be doing okay there. At the very least she kept her head down, finished her schooling inside and got time off for good behaviour.
Jess's release came just after her eighteenth birthday, which I was glad about; since any longer and she would have been sent on to a normal prison. We met in the release room, where she signed for her things and her parole.
She hugged me tight for what seemed like an hour; I felt the form of an adult woman pressing against me, where I had only been used to a child before. She was still shorter than me, but she had grown up.
Jess was quiet during the car ride home, except to ask where we were going; I explained I'd moved house, gotten a two-bedroom place for us since the divorce. When we arrived I showed her around and she remained quiet. It was only after I commented that her room was smaller than her old one that she whispered warmly that it was perfect and she hugged me again, pressing her face into my chest and she cried.
I let my daughter get it out; the mass of bottled up emotions she had been concentrating within her. Not letting go of me she sobbed as she told all of her fears, the possibility that I might abandon her, that she might go back to prison, that she had no future, that her mother might come back . . .
(Of course she wouldn't know that her mother could never come back. A couple of years ago during the divorce she had shown up drunk and tried to attack me. I lost my temper and snapped her neck. I threw her body off of a bridge and with the alcohol in her blood the coroner concluded suicide. I kept all of it from Jess, for her mental safety.)
I pulled Jess off of me and looked her in the eyes. I said that I would be there for her, for as long as I lived, unconditionally. I told her I loved her more than any other person. Jess replied likewise and said she owed me everything.
That evening we had a takeaway and just watched TV together, enjoying each other's company. I decided to turn in and Jess followed me up.

I was just falling asleep when I heard my bedroom door open. "Daddy, are you asleep?" (Jess had been calling me 'Dad' since she was ten, but on seeing me today she had gone back to 'Daddy'.)
"Not quite, darling, is something the matter?" I asked in the dark.
"I don't want to be on my own tonight." She said nervously. "Daddy?"
"Okay." I replied "It's a bit of a shock being on your own again isn't it, having a room to yourself again? Still you're a grown woman now; just this once, darling." I lifted up the covers on my bed and I heard her shuffle over until she found the bed in the blackness.
Jess climbed onto the bed and slid in between the sheets. Her hands and legs found my body and she pulled herself against me. "That's nice." She said softly as her head rested on my shoulder.
Something was amiss, I felt. Suddenly it came to me and my hand instinctively felt across, feeling only hot skin, not fabric. "Jess! Jess, are you wearing pyjamas?"
"Oh Daddy" she giggled. "I'm completely naked. Why don't you take your 'jammies off too?" I could feel her hands now feeling over my chest. This wasn't the touch of a child, it was the touch of an adult; a lover?
"Jess; what are you doing?!" I said with a sense of urgency at the boundary my eighteen year old daughter seemed to be intent on bending, if not outright crossing.
"This is the only way I can thank you, Daddy. I'm here to give you what a man needs."
"No!" I cried out and reached for the bedside lamp. We both squinted as it suddenly illuminated the scene, I lifted myself to a sitting position. "You don't need to thank me at all. And I'm your father, this is just wrong. This isn't how we should be."
Jess looked at me pleadingly. She was sat up too, holding the duvet to cover her chest. "But Daddy, I want to. All the time I was inside, you were the one who gave me hope; you gave me the strength to keep going. All I could think about was you, alone out here. Now I'm out, we're together. We're both adults. I even kept my virginity inside, to save myself for you."
"Look darling, I think you've got things mixed up; one thing that should be two. I'm your father; I'm here to protect and support you. There will be another man out there for you to find; someone your age with whom you can fall in love with and build a future together."
"Daddy; but what about your future? I want us to be together."
"I'll support you until you find your feet, and I'll always be here just in case." I was looking at my daughter torn between the image before me of a naked nymph in my bed, and the person that was my child. I was tempted certainly but I had to think of her actual needs first. "I can't be your lover too, I'm your father."
"I don't care. You're the only man in my life; I want to give you everything. I've had almost three years to think about this and my mind is made up." Jessica said, deliberately dropping the duvet to show off her pert breasts.
One of her legs was wrapped around mine. My cock was erect from the stimulation of her touch and view. Jess pulled away the duvet and took hold of my cock through my pyjamas.
I reached out and grasped her wrist. "No!" I said firmly.
"Trust me." Jess replied.
I can't explain it; my grip slackened and I let go of her wrist. She opened my pyjama flies and pulled my cock out. I don't know why I let her, but I felt I couldn't move, like I was only a spectator as she crossed the line into incest.
"It's so beautiful, Daddy; your cock is gorgeous." Jessica said, in quiet awe. "It's better than I imagined, so much."
I watched as her dainty hands grasped it while her body re-oriented. She stroked my cock a couple of times, which felt amazing, and then she plunged her mouth onto it, taking my eight inches deep into her throat.
Despite my pseudo-paralysis I was trying to stop her, but the moment I felt the tightness of her throat around my cockhead; I gave up and accepted it. Partially because my mind was now flooded with both hormones and a single question; where the fuck did she learn to do that????!
Jess must have read my mind as she came up for air "I did it Daddy! I practiced on Kealy's dildo for months, to be able to deepthroat you! But a lump of silicon isn't a cock; I didn't know for sure until now! Woo!"
And to prove it wasn't a fluke, she did it again; sinking her head down over my cock until I felt it bending with the shape of her throat as her lips kissed my crotch around the base of my cock.
Jess came up again and looked frustratedly at my cock. "Daddy, I so want to make you cum and swallow your cream, but I'm going to have to do that another time." My teenage daughter turned to look at me. "Daddy? Can you take my virginity now please?"
I took a deep breath; this was all happening so fast. "Honey, are you sure this is what you want? I don't want to hurt you. We shouldn't be doing this!"
"I'm an adult now. I know exactly what I want. It's not something normal, but I don't care." Jess said indignantly.
