Lookin forward to a little afternoon delight

I'm 14 and already quite the little cunt. Already a dirty little whore. I dress like a slut, and I fuck around with boys in school. I'll suck cock for an A, and I treat other girls like shit. And I know a secret.
He's a teacher. He gets us to read the classics and prods us for our thoughts. I've wanted to fuck him since day one. I've wanted to fuck him ever since he handed out copies of Huck Finn and winked at me when my dark purple fingernail slid over the raised wording of the title on the cover. I paint my lips for him and primp before his class. I have spent the last semester pouting at him, and in the last class he finally caught me, losing his train of thought mid-sentence.
And now I have a secret which makes me steam. I am searing with anger, and I imagine he can tell. He knows that I know. I have been cutting his class, and he hasn't said anything to the school yet. Finally he sees me in the hall and asks me to come to his classroom after school today.
I have to go. I show up, and like always, primp before I see him. I have swollen red lips and a skirt that just barely covers my ass. And, of course, glasses. He's told me how pretty he thinks I am in my glasses before and I want him to remember.
I walk into his classroom, closing the door behind me. He is sitting at his desk and looks up.
"Yes?" I ask. How indignant I must sound. How unappreciative. How hurt.
"Hey, I'm glad you're here. I wanted to talk to you." I stand, even though he gestures for me to sit. "Come on, don't make this hard for me."
I nod, sucking my cheeks in and not making eye contact. I sit on a desk and he sits on his. He wants to be my peer right now, in his rolled up sleeves and tousled hair. I want to be his fucktoy.
"So what's been goin' on? You're one of my favorite students, I miss you when you're not here."
"I haven't wanted to come."
"Did I do something?"
There is a long pause. I lean back and cross my arms, cocking one side of my mouth just slightly. "I know what you did, Sam."
He pauses. I have never called him by his first name. "Mr.-"
"Sam. I. Know. What. You. Did." I am slow and methodical, catching him off guard. He has known how capable I of this since day one. Men like him can spot girls like me. Humberts always find their Los. I giggle and his face turns angry.
"So what did I do?" His voice chokes.
"She told me-" His head drops. He can't deny it after it gesture like that. "I told you I knew."
"So you haven't come to class because of that?"
This is when my eyes furrow. I have been seathing about this for days and this is the moment it's finally allowed to come forth. "It should have been me." He is not even taken aback. He knows. "If you were going to fuck one of your students, it shouldn't have been that fucking virgin."
"Stop it."
"What the fuck were you thinking? You want me. You want to fuck me, if you were going to make a mistake, to fuck up your career, it should have at least been worth it."
"Stop it."
"I'm going to tell them what you did. I'm going to say you fucked her and came onto me. Said you were going to give me an A if I sucked you off. Said it would have been an A+ if I let you fuck me in the ass-"
"You stupid bitch, shut the fuck up!" He is angry, and stands. "Stop it. I want you to stop."
I pause. It's more fun to watch him squirm.
"I'm sorry. You must have been misinformed. I wouldn't sleep with a student." He sits at his desk, fuming, red.
I stand, walking around to his desk. He is in his chair and I lower down to sit on the desk next to him. "I'll make you a deal."
"No."
"Fuck me and I won't tell." He loathes me as he gets harder. "I'll never say a word." I lift up his face with my fingers. "Cross my heart, Sam."
"You're mistaken." He pushes my hand away, but lets his hand linger on my wrist.
"I won't say a word."
"You don't know what you're asking."
"Yes I do. And I want it." He stands and I grab his arm, squeezing it. "I want it. Now." My eyes narrow and he is getting angrier.
"You think so?"
"Fuck me."
"Shut up."
"Do it, you old pervert." He is seething, and finally grabs my arm. He pulls me off the desk and I gasp for the first time, grabbing onto his arm to steady myself.
He pushes me against the desk and I want his lips on mine. No such thing happens as he slap me across the face. I want to cry with the sting. He turns me around and shoves me against the desk so hard I can feel the bruise on my hips spread. He pulls up my skirt.
"This is what you want?" He pulls down my panties and pulls out his cock. He is already hard, swollen, red, dripping. So am I.
He shoves his cock inside me and holds it there, deeper than I've felt anything inside me. It hurts and I want to cry.
"Is this what you want?" He starts to buck against me, and I can feel it inside my stomach. He is pounding my cunt raw, slamming his hard cock deep inside me. I start to whimper, but he doesn't even acknowledge me. He grabs my hair and pulls it back, and I can feel him ripping my hair out of my scalp with his fist.
"Take it, cunt." I am aching. His hips pound so hard into me that I am slamming into the edge of the desk. I want to scream but as I open my mouth he puts his hand tightly over my throat and starts to squeeze. I can feel my pussy tighten around him, searing pain growing with every thrust.
His other hand comes down hard on my ass and I try and gasp but his hand squeezes tighter. I start to feel myself go limp against him, and I struggle harder for air. He loosens his grip and I gasp hard, wheezing, barely noticing as he continues to slide inside me. I catch my breath and squeeze my cunt on his cock, making him moan softly in the back of his throat. I start to cry as I catch my breath, and tears run down to his hand but he doesn't even flex to see what it is.
He squeezes again, bucking harder. I try and scream, I want to beg him to stop. It hurts too much and I know I am going to be cleaning blood from this pair of underwear tonight. His hand comes down again, harder on my ass. He comes down harder and harder each time.
His hand tightens so hard on my throat I think I may never breathe again and begins to cum inside me. His cum burns in my pussy, and he jerks with each load. He is filling me with cum, epic amounts of cum. As soon as he is done he pulls back and shoves me against the desk. He is gasping, sweating, closing his pants. He takes a few steps away from me as I lie on the desk.
He charges back over and begins to spank me. Each time he hands his hand on my ass I whimper and squirm, trying to move away from his hand. He places a hand on the small of my back and holds me as close to in place as he can. His hand pounds faster and I continue to cry, tears and spit running out onto his papers.
He finally pulls me up by my hair.
"Is that what you wanted?" He is breathing hard, red-faced.
I am silent.
He slaps me across the face. Hard. "I asked you a question."
"Yes." I whisper.
He smacks me again. "Louder."
"Yes." I announce.
He spits directly in my face. "Good girl. Are you going to tell?"
"Yes." He spits again, rubbing it into my face. I am decorated in bruises and mascara tears.
"Are you coming to class tomorrow?"
"Yes."
"Good girl. Now clean the fuck up. You look like a dirty slut."
He walks out. I am on time to class the next day.
