Detention

Today is the day.

The day I finally take what I've wanted for so long. Today is the day of your 18th birthday, the day you reach the age of majority. The day when I can finally act on all the urges I've had for you since I started teaching at your school.

I know I'm taking a huge risk by acting upon my urges but I can't resist them, the need to have you is all encompassing.

I remember the day I first noticed you. It seems like an eternity ago but it's only 6 months that I saw you walking towards me on the corridor, your hair glowing in the late summer sunlight streaming through the windows. Even though I hated acknowledging it I could feel my loins stir as I noticed how beautiful you were and I was sure you could feel my eyes looking over your body.

I put you out of my mind and entered my classroom, ready for the day ahead but all thoughts of that vanished when I opened the door to my first class and saw you at the head of the line.

Since then I've seen you every day, either in my classroom during the week or in my mind when I masturbate while thinking of you. At the beginning I felt like a pervert every time I orgasmed with you in my thoughts but as the weeks passed I began to notice that you weren't as good a girl as you let others believe. Yes, you were an exemplary student but it was other things that let your good girl mask slip, things like undoing an extra button when you entered my class and leaning back when I corrected your work so you could give me a flash of the ripe flesh of your breasts and how your nipples hardened and breathing increased the day we covered sex education. You didn't think I saw but I noticed how you were gently rocking back and forth in your seat. That was the day I realised that you were more slut than good girl.

Today I will make full use if your slutty side. All I need do is somehow keep my concentration for the rest of the day.

Thankfully the day passes quickly. I sit consumed by thoughts of you. Luckily my desk hides my throbbing cock from the pupils.

Then the clock strikes three and the appointed time arrives. I sit upright and watch the door for you. Normally you're first in line but not today. Today you're at the very end and I get to watch you walk to your seat, my view unhindered by your classmates.

There's something different about you, something in your walk, a new air of confidence in your walk. As if you've become aware of your sexuality now that your womanhood is close at hand. You sit and meet my gaze, holding it as you provocatively undo your button as usual but this time parting your legs to give me a flash of demure white underwear.

There's no mistaking the look of defiance in your eyes. As if you're trying to goad me into letting my mask of propriety slip and let everyone see what I presume you can sense - the fact that I want you.

I know I have to gain the upper hand and use your actions against you. I tell you in a voice that I know your classmates will hear that you should do your buttons up and wait after class so we can discuss the correct way to dress for my class. You blush to the point that your face glows as your classmates laugh at you and you fumble to try to do your button up again. Now that I feel that you've suitably been put in your place I return to the task at hand and start giving tasks for the class to complete. Anything that will keep me sitting for fear that my rock hard cock will be on view for all to see.

At last the end of class bell sounds signalling the end of the day. All around us your fellow pupils are laughing and joking as they get their gear together to head off for the weekend.

As instructed you remain seated as your friends make their exit.

I say nothing. Pretending to make myself busy with paperwork, knowing you'll be squirming in your seat not knowing what's in store for you. After a few minutes the sounds outside dissipate and the school returns to it's quiet as a grave status.

You look puzzled as I finally stand and walk to the door and pop my head outside. That look soon becomes a startled one when I turn and lock the door behind me, instructing you not to make a sound as I have a special punishment in mind for you and I don't want anyone to hear.

I return to my desk and make myself busy once again.

After a few minutes I look over the book I'm holding and call to you. "Now then, do you know why I've kept you here?"

"Yes," you reply

"Yes what?" I ask

"Yes sir," you stammar, the flush one more returning to your cheeks.

"Ok tell me, tell me why I kept you back after class?"

"Because of what I did sir."

"What did you do?"

"I unbuttoned my shirt."

"And?"

"And I flashed my underwear at you."

"Yes, yes you did, and if someone else had done what you did what would you call her?"

"Sir?"

"Answer the question! what would you call a girl who practically had her tits on show and flashed her knickers to men?"

"A... a... slut sir."

"Exactly, so what does that make you?"

"A slut sir."

"Speak up I can't hear you."

"It makes me a slut sir."

"What? What are you?"

"I'm a slut sir."

"Good girl, the first step is acceptance now do what you did earlier and be the slut you are."

You avoid my gaze as you part your legs and undo the button you re-did earlier.

"Not good enough, that's not the slut you are."

You hold my gaze this time as you undo another button and hitch up your skirt so you can spread your thighs wider. The sight of the lace of your bra and the wet stain in the front of your panties drives me wild with desire but instead of going to you and teaching you your lesson I instead instruct you to feel your underwear and tell me how they feel.

"They're wet sir."

"Wet? Did you pee yourself?"

"No sir."

"Then how are your pants wet?"

"Because my privates are wet sir."

"Oh? So what does that make you?"

"Horny sir."

"A horny what?"

"Slut sir."

"Tell me what you are."

"I'm a horny slut sir."

"That's better, now we know what our roles are, you're a horny slut and I'm going to chastise you. What time are you expected home at slut?"

"I'm not sir, I mean they don't expect me until they see me."

"Good now put your hands between your legs and pull your cunt stained knickers between your lips"

You comply at once and pull them deep within the folds of your bare lips, moving from one cheek to the other to make yourself ascomfortable as you can with your knickers wedged in your slit.

"Now slut, the buttons, undo another two."

You fumble at the buttons but you eventually get them open and your shirt is open to your navel. I can see that your embarrassment is as clearly visible on your chest as it is on your face.

"Now close your eyes."

Once again you do as told without questioning and you sit up with your eyes closed and back straight, your breasts visible through the V in your open shirt.

I stand up from my desk and silently move towards you. I stand behind you and lower my mouth to your ear.

"Are you ready for your punishment slut?" I growl.

You jump, the sudden proximity startling you.

"Yes sir I'm ready," you whimper.

"Who's ready?"

"The slut is ready."

"Whose slut is ready?"

"Your slut is ready."

I unzip my fly and free my cock, it immediately springs back and slaps against my stomach so full is my arousal. I take it in my hand and push it down as I move to your side.

"That's right, you're my slut, now open your eyes and whatever I have for you you've to take in your slutty mouth."

You reply "yes s" but I stifle the rest of whatever you were going to say when I ram my cock deep into your mouth relishing the gagging sound as I push my deeper and deeper, the convulsions of your throat delicious against my overly sensitive cock and the tears streaming your cheeks spurring my on to thrust deeper still, a handful of your hair in my fist pushing your head down until you gag explosively and pull your head back leaving strings of your saliva from your mouth to my thick shaft. I stand watching as you gasp for air, your breasts heaving with the effort to fill your lungs with enough oxygen.

"Such a good slut, now I want you to do it again, slowly, the way you'd normally suck cock."

"But sir."

Smack! My hand strikes your cheek. "Don't but sir me! Do as you're told!"

"I can't."

Smack! Another one, backhanded across your other cheek. "It's too late now to say you can't, we both know what a slut you are."

"Please sir let me explain" you say as you fight back the tears that glisten in your eyes.

"Ok slut try explain away."

"I...I... I've never sucked a cock sir, I've only ever kissed a boy before"

I almost orgasm right away. The knowledge that you really are my slut that you only act like a slut for me is almost too much for me.

Once again I give you my cock, softly this time, whispering words of encouragement, telling you exactly how I like the head to be licked, how to run your tongue along the length. You learn quickly and soon I'm at the point of orgasm again and yet again I fight to gain control, not yet wanting to release the orgasm I've waited so long to share with you.

"Finger your cunt slut."

You slip a hand into your panties and start to play with your pussy. Alternating between circling your clit and pushing your fingers deep into your tight virginal cunt. You don't need reminding of your other task and you resume sucking my cock. No instruction needed this time. You look into my eyes as you take me deeper than before, not letting the need to gag and breathe stop you but fighting it so you can suck me the way I've always wanted to be sucked by you. Still it's not enough and once again I grab your hair and fuck your mouth as hard and as deep as I can while reaching for one your tits and clawing at them, pinching your nipples as hard as i can. Again you fight the need to gag and cry and take what's given to you until your fingers finish their work and your organ washes over you in wave after wave, your moans travelling along the length of my cock making me lose any control I ever had with you and I pull out and explode all over your face, coating you with my hot sticky cum as you sit back, hair plastered to your face as you fight for breath and gently stroke your cunt.

"Such a good little slut. Now take off your knickers and go stand at my desk."

You stand and bend to slip them off. When they hit the floor a thick stain where they nestled between your lips is plain to see and I know that for you this is your perfect first time. You've only ever kissed boys but you're about to be fucked by a man.
