Once Peter started to walk and talk, he became a bit of a worry and a little pain in the ass. He was always taking off on you if you were not watching him at all times, and the questions never stopped. "But how come," or "But why?" were his responses to any answer I would give him. I still had a great amount of love for my son, but he did test my patience on more than one occasion.

Alexis eventually went through the same stages as her brother, but not as extreme. She was curious, but she tended to remain close to her mother or me, and her questions were not as forthcoming as with Peter. As he grew older, he started rebelling a little bit, trying to establish his own little world. It was the typical stuff that kids went through, hell I could even remember being a pain in the ass to my parents, and my wife and I just let it go as a stage of his development.

It was not as if we did not love our kids, we did. It was just the frustration of dealing with the kids getting through the rough middle years where they where so close to becoming an adult, but still hanging on to the craziness of being a kid. Whereas Peter began to resemble my looks, Alexis became a mirror image of her beautiful mother, with one small change. Her body developed into a perfection of art.

Alex had long blonde hair that hung straight down to her shoulders. She was tall at 5'8", and she was very lean. She was not overly thin like some of her friends, who almost seemed to be just skin and bones and her body developed these amazing curves that were just not fair. I mean, how fair is it for a 13-year-old girl to develop "Playboy" like curves to her hips? I did not find it fair at all, and when Alex discovered the power and domination that came with these looks, she began to use it to her advantage.

I saw my cute, perfect little girl turn into a hot teenage slut right before my eyes! She would wear make-up that made her look much older, and she wore clothes that appeared to be painted on. Her shirts always seemed to press against her firm 34-C breasts and her nipples were perpetually erect. I swear that you could hear the erections grow when she sauntered through a room, her tight little ass swaying seductively back and forth. God, she was a goddess and she was my own daughter.

She began to flirt with everyone, even me, and it opened new doors for her. I noticed that she began to hang out with "older" guys, and I would often wonder if my little girl was still a virgin. She was a bundle of sexuality and she sure knew how to use it. Whenever Peter would have a friend over, Alexis made sure that she would walk right be, stealing the attention in whatever room she walked into. Even my friends noticed it, giving me a hard time about the hot sexpot that I had in my house. If they only knew.

The more provocative she became, the more that she turned me on. I could not believe it, but my little girl was actually turning me on almost every time I saw her. I became one of the masses when she entered the room, and my cock began to get erect every time I saw her erect nipples poking through her shirt. The little tease knew it too, and I noticed that she became more and more flirtatious with me. It was excruciating to see her prance around in front of me in a tight little bra and panties, her youthful body begging for release and touch, and I found myself pounding away on my cock on more than one occasion while thinking of my daughter.

This is not to say that my sex life was not satisfactory with my wife, but there was something about my hot slutty daughter that had my balls boiling. I would fantasize that it was Alexis riding my cock when my wife slammed down on me. With their similar looks it made the fantasy all that easier to imagine, and my own fantasies fueled the desire. As the summer approached, and more and more of her skin became visible, I knew that I had to do something. Something had to be done soon or I was going to burst.

Alexis continued her teasing and flirting, always brushing her breasts against my arm or my chest when she kissed me goodnight and "accidentally" rubbing against me whenever she had the chance. I caught her checking the lump in my pants on occasion, and I wondered if she had the same thoughts that I did. I would run to my bathroom and pound my cock on every occasion that one of these "touches" occurred, and she had me going nuts.

To my dismay, she filled out a bikini even better than her underwear. She had bought a skimpy little string outfit, complete with a thong and high straps on the legs. I thought I was going to cum in my pants when she would prance around in the summer, always showing me her firm ass cheeks. It was hell watching her slink around the house, her body always seeming to touch mine when she walked on by.

I was mowing the lawn on a hot Saturday, the sweat pouring down my body, when Alexis came strolling out of the house in her hot little bikini. I switched the mower to neutral when I got near her, and she smiled at the sweaty mess I was.

"You should take a break daddy," she told me in her hot voice, her ever-present nipples poking straight out. "You are all hot and sweaty, ugggh!"

"I will in a second Alex," I told her as I wiped my arm across my forehead. "I just want to finish the front, than I am going to take a break. I do need to trim the bushes in back later too."

"OK daddy, I am going to lay out in the back and get some sun," she told me with a quick peck on the check before she ran around to the back yard. My cock came to life as her luscious ass swayed in front of my face, and I wondered how many fatherss actually lusted after their daughters. I wanted to fuck Alexis unlike anything else that I ever wanted to do, and my cock throbbed like a raging inferno in my pants. I was not sure how much more of this I could take.....(cont)
