"Hey!" I exclaimed. "You can't do that!"
She pulled back, keeping a firm grip on me with her warm little hand, and said "Sure I can - it's big, but I bet I can get it all in..." She popped my cock back into her mouth, and resumed giving me some of the best head I'd had in years.
"No - I mean - you shouldn't be doing it... it's not right!"
This time she kept up a steady pumping motion with her hand as she drew back and said, "Yes - I know that. It's very nasty for me to be sucking my Daddy's cock..."
"But, I'm..."
"Hush, Daddy. It's nasty to suck my Daddy's great big cock, and that's what makes me so hot doing it. I'm a nasty little girl and I've always dreamed of fucking my Daddy and now that I have the chance, well..." She glanced downward, and I realised that her other hand was inside her panties, as she fingered herself.
Again she began; she pushed forward quickly, and more than half of my length slipped between her widestretched lips. I could feel my cockhead at the entrance to her throat.
Even though I knew that I should stop her, the sensations were so intense and pleasurable that for a moment I could only sit there, looking down at her. Somehow, her top was pushed up, and I could see her pretty tits in their little sports bra. I could see that her other hand, inside her cotton panties, was stroking in and out of her obviously-wet pussy.
Involuntarily, as she plunged forward a bit more on my cock, my hips drove forward, attempting to fuck her hot wet mouth.
"Mmmmm!" she hummed, the vibrations stimulating me even more, and increased her activity.
Suddenly, I felt the head pop through into her tight throat, and she pushed forward all the way to the base of my straining cock till I felt her lips touch my hair; the hand that had been cradling my shaft now slid downward and began caressing my balls, causing me to almost forget how wrong this was and to again surge forward into that wet, hot tight hole.
I could feel my cum beginning to rise in my nuts, and then, suddenly, I remembered again just what was going on, who she was and who I was.
I reached down, pushing her away (not without a certain unregenerate regret as I saw my spit-shiny cock emerging from between her lips... ) and announced firmly, "No more of that, young lady!"
She raised her head, and looked down at me as she absentmindedly licked the fingers of the hand that had been inside her panties (somehow other her hand had recaptured its grip on my shaft and was again gently stroking... )
She looked like a pornographer's dream, kneeling in front of me, my hard cock in her little fist, the flippy little cheer skirt she still wore falling back to almost-modestly hide her wet-pantie-covered mound, top pulled up to show her lovely tits in their modest sports bra, one pigtails' pink ribbon straggling loose, one still in its cute bow, licking her own pussy juices from her glistening fingers...
"You're right," she murmured. "That's about enough of that, I'd say. Now it's time for this..."
And before I realised what she was about to do, she suddenly pulled the lever that caused the chair I sat in to fully recline; since I'd been sort of pushing backward from her, I flopped backward with it.
Another one of those dancer-like moves left me pinned in place as she swung a leg upward and across me and wound up straddling my hips.
"Hey! No..." I exclaimed as I realised what she was about to do, but she kept right on.
Her free hand reached downward, raising the front of her pleated cheer skirt, pulling the crotch of her panties aside, and then her hips surged forward and down, her other hand guiding my cock unerringly to her pussy, and suddenly I felt her sliding the head along her hot, wet soft lips, rubbing it gently against her clit, and then pressing against it until it popped between the outer lips...
She paused then, looking downward at me. Her cheeks were blushing a deep red, and a flush was spreading across the tops of her breasts as well.
"But..." I began.
"Hush!" she said.
She rotated her hips slowly, rubbing my cockhead against the inside of her pussy lips, then slowly sank downward an inch or so, gasping as the thick blunt head pushed past her lips and began to spread her cunt widely enough to penetrate.
