A/N I took a flash fic I wrote and added the smut for this homework assignment. 18+ ONLY. This is for CeeCee

I trembled. Everywhere. From my red painted toes to my brown curls. It was the anticipation, the fear, the whole "forbidden" scenario that had me shaking in my cowboy boots. This was such a cliché, the professor and the failing student, it all makes me cringe. But still I knock on your door and wait for your permission to enter.

I fell in love with you on the first day. Your rusty hair constantly flopping into your summer green eyes and the adorable way you flicked your head to clear them had me swooning. But it was the intelligence in your voice and the passion of your words that had me crash landing at your feet in love.

And now here I am ready to debase myself for a grade. I know I should feel ashamed and disgusted at what I'm willing to do, but I'm too overjoyed by the idea of you touching me to care. It's been my only fantasy since the day I blanked on an entire lesson because you were sucking on a pencil. The way your lips wrapped around that yellow piece of wood had me clenching my thighs in desperation.

Your deep voice calls me into your office, and with my heart in my throat, I enter. My breath catches as I see you leaning against your desk with an unmistakable hunger lighting your eyes. It seems you've been waiting for me too. This couldn't end well, could it?

I stand just inside the threshold, and the gentle click of the door closing behind me makes me jump. My nerves are on edge and my thoughts are whizzing around my confused head. I can't do this, why did I ever think that shy Bella Swan could ever pull this off?! My embarrassment is glowing all over my face, the heat of the red burning all the way down my neck.

My eyes are focused on your feet. You're wearing your usual brown oxfords. The size of them has always impressed me. A little thrill of excitement buzzes through my body at the thought that I might get to find out if the myth about shoe size is true. I drag my eyes up your body, and even now after three lessons a week and an hours tutoring one evening a week for the last six months I still can't get over how handsome you are.

Black chinos do nothing to hide the shape of your legs. In fact the smart casual style gives you a sophisticated look that has my imagination conjuring fantasy after fantasy. I imagine your thighs are thick and strong with a spattering of hair giving them that masculine look that drives my mind straight into the gutter. The charcoal sweater vest over a button down shirt makes you look like a man in every sense of the word. The plum colour of your shirt brings out the green in your eyes, and I am completely mesmerized once again. You dazzle me.

You clear your throat to gain my attention—dear god I hope I wasn't drooling—and my eyes snap back up to yours and off your full pouty lips.

"Thank you for coming, Miss Swan. I know you'd rather be lounging on the quad on a nice day like this but your grades are important. Let's go over your options shall we?" The twinkle in your eyes lets me know your mouth has pulled up into a mischievous smirk. It seems you are in a teasing mood.

"Mr Cullen, I thought we had already gone over my options?" My voice is full of nervous energy.

Another smirk from you with your index finger tapping against your bottom lip in thought. "Yes we did, didn't we?" You throw a wink my way and push of from your desk so your full height is towering over me. You beckon me closer with a curve of your long finger causing a shiver to run through me.

"Why don't you refresh my mind, Miss Swan? It seems I have forgotten what we had discussed."

I walk towards you on shaky legs, a small whimper escaping from me at your words. I can't believe you're going to make me say it out loud. My tongue peeks out wetting my bottom lip and your eyes follow the movement. I've never been more aware of myself in my life. I feel like my every move is exaggerated.

I'm right in front of you now, my nose coming no higher than your Adam's apple—what I wouldn't give to lick and suck on the bulge in your elegant neck—so I have to tilt my head back to make eye contact. Your height is equal parts intimidating and thrilling. I can feel my panties dampen with each passing moment.

"Well, Mr Cullen, either I could spend my every waking moment re-writing my essays and other course work or—." I trail off as the colour of your eyes darkens with every word I say.

You raise an eyebrow and tilt your head to the side. "Or what, Miss Swan?" Your voice is deep and full of lust. It's maddening.

My knees are weak when I reply, my response coming out breathy and full of want. "Or I could do something for extra credit."

A step closer to me and our chests are brushing together. Mine is heaving with the anticipation; my nipples have hardened with your close proximity. The cologne you used this morning is earthy and it completely fills my senses. It clouds my mind and makes it impossible to focus. I pull my bottom lip into my mouth, nibbling and sucking the pink flesh wishing desperately that it was you.

"And what did I suggest you do for extra credit, Miss Swan?" You growl the words out between clenched teeth. I know now that you want this just as much as I do, that you're just as desperate for my touch as I am for yours, and it makes me brave.

"You, Mr Cullen."

The words have barely left my mouth when you've fisted your hand into my brown waves and forcefully pressed your mouth on mine. My hands fly up to clutch at your arms and shoulders. I'm stretched up onto my tip toes—I need to be closer, always closer. The warmth of your big hands cupping my face radiates through me.

We're chest to chest with every inch of our needy bodies rubbing together. Christ the friction is delicious but it's not enough I need more, so much more. The ache between my legs builds higher and higher. And then we're spinning and you have me pushed up onto your desk—my denim mini skirt bunching up at my waist—not once taking your kiss from me. You slide in between my open legs, your obvious desire grinding oh so hard against my wetness.

Your teeth tug on my lips, the sting of the bite being quickly soothed by the lapping of your tongue. I'm struggling for breath but I don't want you to stop. You seem to sense my dilemma though and you move your lips across my check and onto my neck leaving a trail of burning passion as you go. You fasten your mouth onto the curve where my neck meets shoulder and you suck, lick and bite me until I cry out. I'm sure I'm being ridiculously loud but I can't seem to stop myself.

A chuckle rumbles from your throat. You press your covered-in-scruff cheek against my overheated one and whisper in my ear, "Tell me what you want, Bella. Just tell me what you need and I'll make you feel so good."

I almost come undone from your words alone. The frenzy you've worked me up into has me forgetting all about my shyness and insecurity because I answer in a voice full of desperation, "Please, Mr Cullen I need you to fuck me."

It seems my words have broken down the last of your control. A roar rumbles up from your chest and out of your mouth as you roughly pull my black tank top up over my chest exposing my lacy black bra. Not wasting a second you tug the cups of my bra down revealing my rosy hard nipples and creamy flesh. Goosebumps flow over my uncovered skin as you grasp both mounds in your hands.

You squeeze my full, pale breasts together and flick your tongue over both of my nipples in one long lick. The pleasure of feeling your tongue on me coupled with the cold air hitting my wet nubs has me whimpering and moaning into the empty class room.

I buck my hips against you, feeling your cock stiff beneath your pants. Your moans against my nipples feel so good. But then you move your mouth back to my ear. The wetness of your lips and the heat from your panting breath sends shivers right through me. God I want you.

"Can you feel that, Bella? Can you feel what you do to me?" You press your cock against my pussy turning my moans and pleas into one long keening whine of need.

"Do you want my cock, Bella?"

"Yes, fuck yes." I practically scream at you.

And then you're tugging my black panties aside—I wore a matching set just for you, did you notice?—and I'm wet, so fucking wet for you. You stroke your fingers over my bare lips, pulling and tugging at the swollen flesh. Your fingers slip and slide in my folds, circling over my engorged clit and dipping into my pussy. My hips circle against your hand pushing your fingers into me deeper and deeper.

"That's it, baby. Fuck yourself on my fingers. Christ, you look so sexy." Your words are growled against my cheek, you make me feel so good.

Your fingers are curled inside me, stroking in just the right way to make me climb higher and higher into the heavens. I'm rushing closer and closer to bliss, my head is thrashing form side to side and I'm begging. All dignity has left me as I plead with you to make me come.

When you pull your fingers from me—glistening with my need—I feel like I might die. The shock of having so much pleasure one moment and then having it taken away the next is a massive jolt to my system. But then I hear your zipper and the swoosh of your trousers falling to your ankles, and my heart beat picks up once more. This is it.

I tip my head forward and fix my eyes on the white boxers hugging your hips. The dip of your "V" looks so incredibly delicious I start to salivate. I hope I get the chance to lick those lines one day. My mouth drops open as you pull your boxers down and your cock bounces free. Your bigger than I imagined, and thick too. I won the professor lottery. I think the lust has fried my brain.

You pump your fist over your impossibly hard cock once, twice, and then you're lining up against me. We both watch with open mouths and panting breaths as you push, push, push yourself into me. You stretch me so good as I grip you so tight. We're both cursing and grabbing at each other as you bottom out in me. Your hips are pressed so close to mine, it's other worldly the way I feel right now.

And then finally you're moving. You thrust into me achingly slow, but you're hitting me deep and hard so I don't complain. I'm not even sure I could even if I wanted too as you've rendered me incoherent. Your hands are gripping my waist so tight, your fingers digging into me and I'm sure I'll have bruises tomorrow. I'm ecstatic at the thought of wearing your mark on my skin. I have one hand behind me bracing me on your desk and the other is fisted in your shirt.

We're sweating from our actions; the heat from both of our bodies is volcanic. I tingle all over. The smell of sex permeates into the room. I start to spiral up, up into the clouds again. The pleasure tightens my stomach and my legs start to shake. I'm pleading again. If he stops this time I know I'll die.

A swirl against my clit from your expert fingers and I'm falling and flying all at once. My hearing goes and my vision blurs. My toes curl in my boots as my fingers claw at you. It's the closest I've ever felt to god in my life.

I come crashing back to earth just as you take your divine trip. Your thrusting is erratic, your grip tightens and I feel you twitch and spasm as you release into me. Once all movement has stopped and you slip from me, pulling my panties back into place as you go, you smirk down at me.

You expel a breathless chuckle. "Yeah, an A for sure." You lick your lips and wink and me.

I laugh, full and throaty. I'm floating sky high right now. I know, deep down, that when I'm lying in bed tonight I'll start to freak out but right now all I feel is bliss.
