"Face down, ass up"

You croak out through parched lips. Your initial shock had dissolved into disgust which is now boiling over into rage. Who is this woman--no, this thing--that called you "daddy"? It certainly isn't your daughter. It couldn't be the brilliant young woman that you had worked so hard to provide for shaking her ass in front of you. This was just a slut, daring you to tear up her ass. And now you are going to make the bitch regret ever asking for such a stupid thing.

"What was that, Daddy? I can't hear you?" Kelly replies, her brow furrowing in confusion. With how softly you had said it you don't think she is playing with you.

"I said get your face down and ass up!" You roar, crossing the room to where she was presenting herself.

You don't give her the time to follow the command. You grab a fistful of hair and slam her face down onto the hard wooden surface of the desk. The impact makes her grunt. You lean over her, pressing your body against her back. You grind your bulge against her pert backside feeling the heat of your precious daughter's sopping wet pussy. Leaning in with your mouth inches from her ear you snarl "Sluts are only as good as the holes being used. If I'm fucking your filthy asshole then I don't need to see your face, do I?"

The mischief in Kelly's eyes had disappeared. Instead, her expression was now full of lust with just a tinge of fear. You don't need the encouragement, but you appreciate it all the same.

"No, Daddy," she manages to squeak out around the pressure you are exerting on her face.

"That's right. All I'm interested in right now is this." You use your free hand to give Kelly's ass cheek a slap, at least as hard as the ones you gave her face. She squeals and jumps in your grasp. "Did that hurt?"

"Yes, Daddy."

"Good. You've been a bad girl and you deserve every bit of pain you get." You give her ass a rough grope before pulling down your fly and finally freeing your painfully hard cock from its confinement in your pants. You press your erection against your daughter's bare ass, sliding it between her toned cheeks. You grip it in your hand, lining the head up with her puckered anus.

"Oh wait, I should lube up before I split you open. A whore like you should have some on hand, right?"

"Yeah," you relax your grip on Kelly's hair as she looks toward a set of drawers beside the desk. "There should be bottle in th-AAAAAAHH!" She screams as you pull her head back and slam your dick deep into her asshole.

"Would you look at that? Looks like you're good to go without it."

Mr. Milton chuckles. "Now that's just cruel."

You don't even hear him. You are too overwhelmed by the sensation of your daughter's hot tight butthole wrapped around your member. Your sudden entry causes her to clench up, her rectum **** to rid itself of the intruder.

"Can you feel that, baby?" You press yourself deeper into her until you balls are flush against her rear end. "That's your daddy's dick in you. Your real daddy. Your only daddy."

"Ungh!" Between the pressure in her ass and the angle you are bending her neck, a strained grunt is the best response she can give.

"That's right. And now your real daddy is going to fuck your bitch hole like those other bastards wish they could." You grip her waist and slowly draw your dick from it's sheathe before slamming it back home. You gradually build up steam, finding your rhythm and soon you are pounding your daughter's teen tush like a jackhammer. You are delighted by the little gasps that leak out of her with every thrust.

"Daddy, please," Kelly breathes as she turns her head, her eyes meet yours for the first time since you began violating her tender anus. They're full of tears. She seems to be pleading for something but you can't imagine what. For a moment, you almost recognize her as the little girl you taught to ride a bike before remembering that she's just a slut that stole her face and name. You wrap an arm around her throat, pulling her into a headlock as you continue your anal ****.

"Please? Please what? Please raise you to be a woman with some god damn self respect? Please teach you not to spread your legs for any thimble dick asshole that comes along? Looks like it's too late for that." By now, she is writhing in your arms, struggling for breath. You are vaguely aware of Milton saying something to bring this to your attention but you don't care. It feels so good with this whore thrashing against you, her ripe ass squirming on your cock. You may have failed her as a father but you'll make up for it as her master. You make this silent promise as you give a final thrust, pulling Kelly completely up off the desk to dangle in your arms as you fill her backdoor with a massive eruption of semen.

As your orgasm subsides, you pull your daughter off your softening dick and lay her unceremoniously on the desk. She coughes and weezes, trying to catch her breath. Her eyeliner is streaked by the tears running down her face. You look on, disinterested, not bothering to put away your cock. Finally after she catches her breath, Kelly pushes herself into her side and meets your gaze.

"Daddy..."
