Chapter 3: Kristen Gets Things Started

My dad held the door to his office open for us and once we were in he closed it behind us, making sure it was securely locked. He took a seat on the couch in his office while Kristen and I moved next to each other’s with our backs to the big windows that gave my dad’s office a terrific view of the city. We looked at each other and then in unison we dropped our coats to reveal our outfits.

“Well Daddy,” I said in my best little girl voice, “School’s in session and we’re ready for our lesson.”

My dad may have been a father and uncle, but he was still a man so he couldn’t help but stare at us. Our skirts were so short they really didn’t do much to hide anything. Without our panties just any time we moved he got a glimpse of either our ass or pussy. The white shirts we wore were a couple of sizes too small, making them stretch so tight that I thought the few buttons we left done would burst if I took a deep breath. The material was so thin and light the brown outlines of our hard nipples were clearly visible right through it. With our hair tied back we looked younger than our years and for Kristen, who already was petite, that meant she looked about fourteen!

“Damn girls,” he said with a husky voice he always got when he was horny, “You’re looking awfully hot today! So what do you girls want to learn today””

Kristen was the first to respond, slowly moved towards him, her hips wiggling with each step and a saucy look on her face. She moved up close to him, one leg between his, pressing his knee against her bare pussy. “Mmmmmmm, you KNOW what we want.” She pulled his head to her and I could see her mouth moving as she whispered softly into his ear, “Fuck me Uncle John. Fuck us both.”

It was so incredibly sexy seeing her asking my dad to fuck us in that sexy way. The best part was it appeared so natural, like it was perfectly normal for a seventeen year old niece to ask her forty year-old married uncle to screw her. Well, in our family that was actually the case. It WAS perfectly normal and acceptable and I knew my dad was going to take full advantage of it today.

As Kristen slowly unbuttoned her blouse I could see the transformation taking place as my dear father began to fill with passion and lust. I watched with fascination as he looking at us less as his daughter and niece and more as two little teenage sluts whom he wanted to take as his own, to do anything he wanted to (and we meant anything). I could tell from the heaving of his chest and the flush building on his face that his breath was quickening and his pulse was speeding up. He licked his lips subconsciously as Kristen slowly revealed more and more of her sexy little body.

Seeing the sexual lust building in him was almost like watching an old werewolf movie where the innocent man changed into a raging animal except my dad was becoming an animal filled with pure lust and sexual craving. To tell the truth, I love seeing my dad this way. It always makes me feel incredibly sexual knowing I can make my own father want his daughter this badly. I liked being slutty enough that he desires my body more than anything else in the world at that moment. I feel truly fulfilled knowing that as his only daughter I am the only one that can fulfill his every sexual desire, craving, and fantasy. Not even his niece can take the place of his only daughter.

As these thoughts went through my increasingly horny mind, I watched as Kristen stripped for my dad. First the shirt came off as she rubbed her small breasts, pinching her hard nipples for him to see. The she turned away from him, unzipped the side of the skirt and let it drop to reveal her tight little ass. The knee socks and shoes disappeared and there she was, stark naked waiting for my dad to take her. I loved her sexy little body and she knew how to show it off.

Kristen leaned over and spread her butt cheeks apart, giving her uncle an eyeful of her clean little asshole and tight wet pussy. She reached between her legs and ran one finger from her asshole down to her clit, pushing her way through her swollen pussy lips, stopping just ever so briefly to push it inside of her to wet it, and then continue on its way to her clit which was craving attention.

My dad’s eyes never left her ass for an instant, watching her every move, listening to her every moan as she fingered herself in front of him like a cheap whore. I could only imagine the nasty thoughts going through his mind. Hell, she was getting me excited as well with her slutty little show!
