Any other day I would dread going into work. The thought of facing all those annoying teenagers makes me want to stab out my eyeballs but not today. No, I've been waiting for today for a very long time. Ever since I found out her birthday I've been waiting for this day. And now it's here. Today I will fuck her senseless...

I was walking past the sports hall when I first saw her, the sweat of her body made her shirt slick, highlighting every curve... My cock throbbed instantly. I knew I had to have her.

Every day since I've been imagining what it would be like to fuck her, to feel her body quiver under mine as I enter her, watching her bite her bottom lip to stop herself from screaming, sucking on those gorgeous pert breasts that will bounce so hard with every thrust of my cock...

I can't tell you how hard it's been, not being able to touch her during class, forced to wait until she turned eighteen. Thank God I don't have long to wait anymore. Just a few hours until last period, when I can ask her to stay behind to talk about her mediocre work. This is just an excuse. She's an excellent student, the best actually. But I'm going to use that desire to succeed to my advantage...

*Seven hours later*

Here they come now, fresh faced and eager to learn. Who am I kidding? They don't want to be here anymore than I do. All I want is her.  Fuck, is it just me or is she looking particularly slutty today? Her skirt is the shortest I've ever seen it! Not that I'm complaining mind, it's just my cock is fucking rock hard. There's no way I can stand and teach now.

Instead I got them all to read their textbooks, prompting numerous groans but I didn't care. I was too busy imagining her groans as I pump by hot thick cum inside her....

I don't care anymore, I sit and stare at her with a hand gently teasing my cock through my trousers. That's when I notice that she's not sitting where she usually sits. She's sitting at the back of the classroom instead of up at the front. I wonder why?

I get a fright when she suddenly looks me straight in the eye and smirks. What the hell? Did she notice me staring at her? Fuck that was so hot though, she really is a slut today. And that's when I realise why she's sitting at the back. It's so that I can get a good view of her cunt...

Her skirt is riding up, exposing her slender thighs, teasing me as I imagine how they'd feel under my palms... Her shirt is hardly buttoned, those pert breasts bursting out begging me to squeeze them, to bite on her erect little nipples... I can feel my cock oozing with pre-cum as my eyes roam all over her, watching her watching me...

I know now she wants it just as much as I do, even if she's just teasing me I'm still going to pound her... She uncrosses her legs and I nearly blow my load. She's not wearing any panties! God she's such a fucking horny bitch, even from here I see her pussy lips glistening with her juices...

The bell finally rings and everyone hastens for the door. I don't need to ask her to stay behind, she stayed of her own accord. My cock is fucking aching as she walks towards my desk and leans on it, shoving her cleavage in my face... I'm going out of my fucking mind with lust for this girl...

"Like what you see, sir?" she purred. Unbuttoning the rest of her shirt...

"Definitely, I didn't know you were such a slut..." I teased.

"A slut?" She walks around my desk, and leans over me, "you didn't seem to mind me being a slut when you were stroking your cock, sir..."

Her breath is warm on my face, I unbuckle my belt and pull down my trousers and boxers, exposing my huge erection to her smirking face.

Her eyes light up when I say, "Of course I didn't mind, my cock loves slutty teenagers..."

I grab her hair and force her head into my lap, holding it there until she gets the hint and starts sucking me off. Mmm she's definitely done this before, teasing the head of my cock with her tongue before sucking the length of it... I wonder how many guys she's had inside her... I can't help it, I start to thrust my cock in her mouth, eager to cum... She's only too happy to oblige, she wanks me harder, faster, sucking so deeply that I can't help but moan. I feel it building and so does she, she runs her tongue along my slit and I explode inside her hot mouth. My cum is fucking endless, my cock throbbing so much inside her that she can't swallow it all, I watch as some of it trickles down onto her chest...

She's far from finished with me though as she pulls up her skirt, exposing her shaved pussy... She knows I want her, my eyes drinking her in... I force her back onto my desk, her legs spread wide, I hear her panting. I slowly shove my fingers inside her soaking wet pussy, watching her writhe in pleasure at my touch... I finger her hard, watching as she teases her own nipples, feeling her close to climaxing... When she can take no more, I gently rub her clit, making her cum so hard that I can feel her cunt tightening around my fingers...

She's utterly breathless lying there, with her long hair cascading over her breasts, she looks angelic in this moment, despite being a slut... She's still far too innocent for my liking though... As she gets her breath back, I undress, I do it quickly while her eyes are still shut. They open suddenly when she realises that I've climbed onto the desk, that I'm on top of her and that there's nothing she can do. She panics, trying to push me off of her but there's no way, a slip of a girl like her can overpower a full grown man...

I pin down both her arms over her head with only one of mine... The other is free to do what I like...

"Please... let me go, I don't want this!" she begged.

"Sssh... that ain't gonna work on me, we both know you want this..." I push my cock against her pussy lips, making her squeal...

"No! Please stop, I'm still a virgin!"

"Mmm is that so? You seem too confident to be a virgin..." I run my hand over her breasts, squeezing them, watching her fearful face struggle not to moan as I suck on her nipples... They taste so good...

"Even though you're begging me to stop, you're awfully turned on... sluts like you need to be punished..."

And as she tries to push me away again, I thrust my cock inside her. Hard. Making her cry out. She was a virgin after all... Fucking hell she's so tight! I pound her hard and fast, watching as she finally gives in to the pleasure and wraps her legs around me, pulling me deeper inside her...

I kiss her, shoving my tongue in her mouth and letting her suck it as I violate her cunt. Her tight pussy squeezes my cock, making it throb and ache, I don't want to stop fucking her... She arches her back, thrusting her hips up so that her clit is grinding against my body, trying to make herself cum... She's such a dirty bitch... I feel it building inside her, her cunt tightens around my cock, squeezing my cock so hard that I'm going to explode any minute. I place my hand around her throat and gently squeeze it, she cums so fucking hard and fast that I'm not prepared. Her tightening cunt squeezes the cum straight out of my cock and I pump it straight into her aching pussy... I cum so hard that even after climaxing I still feel it trickle out of me and into her...

Afterwards, we dress and she leaves. She transferred to another class after our encounter, hoping to put it all behind her and forget about it. But what she doesn't know is that I secretly filmed the whole thing...
