Still sore from our last meeting, I knock on the Professor's door, no hesitation, only excitement this time. At his call to enter, I slip inside, closing the door behind me. The vanilla tobacco scent of his office embraces me. A scent that's now familiar and brings to mind very naughty, dirty things. From now on every time I smell vanilla, I'm going to remember him and everything he did to me.

Professor Roux stares at me, taking in my schoolgirl uniform. I try not to fidget, nervous tension skittering through me. I hope this is what he meant. I have on a tiny little plaid gray and blue skirt that barely covers me, no underwear, and a blue cardigan only held together by two buttons. My breasts spill over the top, my nipples almost coming out and my midriff shows, my belly button ring flashing in the dim light.

I'd worn a big raincoat over top of it which I shoved in my bag before knocking. No way was I walking across campus dressed like this.

"That's much better."

Relief soothes away my nerves. "Thanks, Professor."

"Come here." His voice is stern, his expression revealing nothing.

I toss my bag to the same spot by the door and walk over to him. I look up through my lashes, meeting his blazing blue eyes. I sure am a sucker for blue eyes.

"Bend over the desk."

Another round of naughty schoolgirl? I hope it ends with me getting fucked this time. I saunter to the desk, making sure to brush my tits against his arm. I place my hands in the same spot and lay my top half across his desk, my ass in the air, my skirt riding up, revealing the bottom curve of my ass cheeks. The only thing on his desk is the ruler, just like before.

He comes to stand beside me and flips up my skirt, a small hiss escaping when he sees my lack of underwear. His hand grazes my sore skin, his fingers tracing the marks still branded onto me.

"Beautiful. Does it still hurt?"

My breath shortens from his light touch. "A little."

"But you learned your lesson."

"I did, Professor."

"Excellent."

His hand teasing me drives me crazy. "Please, Professor."

"Please, what?"

I splutter, my pussy already growing wet. "Spank me, fuck me, touch me, anything. Just please."

The Professor shoves his hands between my legs, grabbing my pussy in that same way as before which makes it pulse against his palm. I don't know what it is about that, but it is one of the hottest things ever done to me. He clenches his hand, gripping me harder. I moan and push back against him.

He steps away, his hand disappearing from me. An embarrassing whine escapes my throat.

"Stand up and turn around."

I push up with my hands from the desk and spin to face him. He steps close and grips my upper arms, before burying his face in my neck, kissing and licking his way down my collar bone, nipping at the heaving flesh above my sweater.

"Take off your shirt," he commands.

I bring trembling fingers up to my cardigan and pop open the buttons, my breasts clad in a tiny, white, see-through bra spring from it. My nipples poke at the fabric. I let the sweater slide off my arms and down to the floor.

"Bra too."

I slip the straps off first before reaching back to unclasp my bra. It joins my sweater on the floor.

His eyes narrow on my tits and hard nipples. "Leave everything else."

I nod and bite my lip. "Yes, Professor."

He gestures towards the desk behind me. "Now, sit on the desk and open your legs."

I shiver and obey, hopping up and hitch my skirt up so I'm completely on display. The chilly air of his office brushes against my open pussy. The wool of the skirt scratches at my ass, but the desk is cool on the back of my legs.

He takes off his bow-tie first and then shrugs from his tweed jacket. He releases the cuffs of his shirt and unbuttons the middle with torturous and slow movements. He tosses both onto his leather chair. His chest is pale and lean with defined muscles and not a hint of body fat.

He is seriously fucking hot.

I want to lick him all over, to taste every forbidden inch of him.

He walks over to me and runs his hand up my legs and up my skirt, teasing fingers making feather light touches against the inside of my thighs and over my mound. My legs twitch in response, opening wider, inviting him to explore further.

Instead, he continues up my body until he reaches my tits, plucking my nipples. The sting shoots through me, traveling up and down from the top of my head to the tips of my toes. I suck in a hissing breath through my nose.

"You have the most glorious breasts, Amanda."

I smile a little, pleased with his words. "Thank you, Professor."

He takes both of my nipples between his thumbs and forefingers, twisting and pulling. I almost come off the desk and attack him, barely controlling myself and instead wrapping my legs around his waist instead to bring him closer.

His hard bulge covered by his pants is scratchy against my pulsing, wet cunt. I rub against him, needing the friction.

It's strange being naked in front of someone who is basically a stranger. With Scott, it was different. I know him better than I know anyone and I was also a little bit tipsy the first time. And heartbroken.

But with Professor Roux, I can't believe myself. I am sensual and fearless and probably not a little bit crazy, but it feels amazing and freeing.

And the taboo of it all turns me on even more. The fear of getting caught. It’s forbidden. I could get expelled and he would get fired. Or maybe Sara could catch us and join in. Two items checked off my list at once.

The thought makes me tremble with excitement. I like this new side of me. Taking risks and trying new things. If they were all this pleasurable, I was in for some truly wonderful few months.

And. I. Could. Not. Wait.

He slams me back against the desk and jerks my legs open as far as they will go. One of his hands returns to my breasts, switching back and forth between them, and the other slides into my drenched pussy. He pushes several fingers inside me with no warm up or warning, stretching me to the brink of pain. I moan and try to open my legs more, squirming and gasping. I’m on the border of too-much when his thumb strokes my clit and I settle into not-enough.

It feels amazing.

He twists his hand and my pelvis rises from the top of the desk, my eyes rolling in the back of my head. His head comes down and he takes one of my nipples into his mouth as he keeps twisting and pumping into my pussy.

My pulse speeds into overdrive and every single one of my nerves cries out as warmth washes over me. He sucks hard on my nipple and twists his fingers in just the right way, hitting just the right spot.

I come apart.

I shudder and jerk and tremble and groan, his office spinning. I stare at the ceiling and gasp for breath once he pulls away from me.

Before my body stills and calms, he bends my legs up so my heels rest on the edge of the desk. I am completely open to him. He kneels down and takes my still clenching pussy into his mouth, sucking at the center of me so hard I see sparkling colors glitter across the ceiling of his office.

He pulls away and looks up the length of my body at me. "I did not give you permission to come."

"I'm sorry, Professor." A total lie. I am not sorry at all. It had been amazing and I regret nothing. At. All.

He leans back, a grim smile pulling at the corner of his lips. "You will be."

My heart skips a beat, wondering what the hell he has in store for me now. If he doesn't fuck me, I will regret it. I want him to fuck me more than I want extra credit right now.

His hand comes down straight on the center of my pussy with a gentle slap. My legs twitch in response and I gasp. It doesn't really hurt, but it surprises me. He slaps it again, each strike getting a little harder, but nowhere near as hard as he'd spanked my ass. A flurry of strikes rains down, the sound loud in the otherwise quiet office, my moans and squeals joining the noise.

"You must learn to follow the rules, Amanda. There are consequences for our actions."

I can barely focus on his words, too overcome with arousal and a little bit of shame for enjoying this so much. He grabs the ruler from the desk and my breath falters. He's going to use that there?

He gently slaps first one breast, then the other.

The Professor smacks my nipples and the tops and sides of my tits with the ruler, over and over until my breasts turn the same color as my ass. My arms tremble as they fight to keep me upright. The sting spreads throughout my tits and shoots straight to my core, making it tingle with arousal.

His intense stare meets my eyes, his expression still stern, but his pupils are dark. He's loving every minute of this.

So am I.

My head falls back and my eyes close as he alternates uses the ruler on my tits and my core. I fucking love being a naughty, punished schoolgirl.

The ruler clatters onto the desk and his whole hand comes down with a harder strike than the others over my cunt and the crevice of my ass. I cry out and raise my pelvis, another orgasm hovering over the edges. My eyes are scrunched shut so tight I see the night sky.

And suddenly, his cock is sheathed fully inside me. I didn't even know he had pulled his pants down. I cry out, my hands slapping the smooth wood, searching for purchase on the slippery surface. Everything is extra sensitive and it's almost too much. It's too much. Too strong.

He grabs me by the hips and slams into me again. He hits a deeper spot within me. A spot that's never been touched. Even farther than Scott, though barely. The crook in his dick reaches up and presses against my G-spot.

With my first orgasm barely over, the second builds fast. He pumps in only a couple more times and that's all it takes for me to cry out and clutch his arms, needing any anchor to keep me from sailing away.

He pulls out of me with a growl. "Again? I told you. You are not allowed to come without my permission."

I fight to catch my breath. "Sorry, Professor."

"That's not good enough. I've tried to be patient with you, but you are a slow learner."

He yanks me up and forces me to bend down across the desk. I can barely stand so he does most of the work of getting me in position. At this point, I don't care what he does to me, I know whatever it is, I'll enjoy it.

"I thought I made it clear, you are here at my sufferance. You are here because you want something from me." The ruler comes down on my ass with a smack. "If you want your extra credit, you are to dress and act appropriately. You have to follow the rules." His ruler comes down again.

"Yes, Professor." My voice is breathless and squeaky from the searing pain on my ass.

"You seem to have a hard time learning. Instead of working harder on my class, you came dressed with the intent to seduce me and tease me to get a better grade. But when it came time for you to earn your higher grade, you came dressed like a dowdy secretary. And here you are, and I thought you were finally getting it, but you haven't earned an orgasm yet. You took it without permission. Twice."

"Yes, Professor. Sorry, Professor."

He continues to spank the skin that still burns and aches from the day before. It hurts, a lot, but somehow it still makes we even wetter. Who am I? How do I like this? Is there something wrong with me?

When Scott had been rough with me, it had been my favorite part. And now I'm getting spanked across a desk just like what happens in those naughty books I enjoy so much, and it's one of the hottest experiences of my life.

Is this why sex was so boring with Adam? Because he'd never been rough. He hadn't been too romantic and sweet either, but is this what was missing? A little bit of rough play and pain thrown in? Giving up a little bit of control?

Or am I just having fun exploring these new sex adventures?

Either way, I'm definitely making up for all the lost time now.

Professor Roux's ruler comes down with one final, brutal, spank. It reverberates throughout my entire body, flushing my nerves with heat and desire.

He kicks my feet farther apart and rubs my aching cheeks. "Have you learned your lesson?"

"Yes, Professor."

"Wonderful. You're finally learning. You're finally understanding the rules. That's good."

His hand darts between my thighs and he pinches my clit. I gasp and moan, opening my legs wider. I can't get them wide enough. He pinches it again. He's trying to drive me completely crazy and it's working. His other hand grabs my side ponytail and he yanks it until my head rises from the desk.

"Do you have any idea how sexy you are? Bent over my desk, your ass red from a spanking, your little schoolgirl dress bunched around your waist, your soaking wet pussy glistening and begging to be fucked?"

I don't know how to respond. He keeps pinching me and my scalp stings from his grasp on my hair and his words send a thrill rushing through me. I'm wound so tight, one more pinch and I may shatter and come again without permission.

I enjoy the punishment so much, I don't care.

The Professor bends over me and nips the back of my neck with his teeth. His fingers, soaked with my juices, slides up the back of me and he shoves two of them into my tight back ring.

I'm still a virgin back there, and I'm not sure he's the one I want to give that up to, but I am flying so high I can't think of anything he might do to me that I would say no to. And anal sex is definitely on my list of things to try. I've been developing another list. Not just people to fuck, but sexual acts to try.

I want to be tied up and blindfolded, I want someone to take my ass, I want to fuck a woman, I want to be fucked outside, I want to give or have an orgasm in public, I want to be penetrated in all my holes at the same time, I want to be covered in whipped cream and chocolate sauce and have it licked off me, I want to try anal plugs and nipple clamps and shibari and maybe even a riding crop. I've been doing a lot of research online and there's so many possibilities out there. So many toys.

I may have missed the beginning of the party, but I’m going to sample everything on offer now that I’m here.

He pumps his fingers in and out of my rear for several minutes, his other hand still yanking on my hair. With every plunge, it stretches me and pulls as my tingling, warm ass.

It feels divine.

The Professor releases my hair and shoves me all the way back down onto the desk. The wood chills my nipples, making them pucker even more. He spreads my cheeks and I'm certain he's going to plunge in with no warning or preparation and I'm terrified. But also excited.

Instead, he slams his long cock into my pussy.

Hard.

Oh. My. Word.

My hands scramble for something to hold onto, for an anchor, my tits squeaking across the top of the desk. This is my new favorite position; his dick reaches so deep inside me it makes my belly ache. With each stroke, he slides all the way out of me, rubs the head of his cock between my folds, and shoves back inside. He holds my hips with an almost bruising grip, yanking me back towards him, his balls slapping against me. An orgasm starts to build and I fight against it. As much as I enjoy the spanking, I'm not sure I can handle any more today. My skin still burns from his punishment and will for days. It will be a nice reminder that will probably keep me horny long past the time it fades away. Going to his class is going to be difficult, watching him teach and knowing what we've done together.

Maybe I'll need more extra credit down the line. Not part of my list, but still fun as hell.

The Professor keeps fucking me, sending me closer and closer to oblivion.

"Professor, please. Can I come? Please?" I've begged and apologized more today than ever in my life and I don't give a shit. I just want to come with his dick buried deep inside me. I want to clench him with my pussy until he finally loses that damn control.

Instead of giving me permission, he pulls out of me completely. I almost sob, actual tears spring to my eyes. Dammit. Frustrated, I scoot back, trying to take him back in me.

He swats my sore ass. "Stop. You're finally getting it, don't throw it all away."

I subside, a little sullen. "Yes, Professor."

"Don't worry. I'm going to give you a reward."

He buries his face between my thighs, his mouth and tongue swirling and sucking and nipping at my cunt, my ass. His beard scratches and scrapes at my tender skin. We are both ravenous as he makes a meal of me. I whimper and try to keep breathing, try to keep quiet. My entire body trembles with the force of trying to hold back the waves of pleasure peaking within me. Fuck. It feels so fucking good.

He raises my hips so he can reach the very sensitive bud and nibbles and sucks on it, lapping it and traveling back to my ass. His tongue pushes me to new heights.

"Fuck, Professor. Please, let me come. Please. Please. I can't. I can't hold it back much longer."

He pulls away long enough to say, "Permission granted." He delves back in with a growl and I slam my forehead onto the desk as euphoria spreads through me and I float, float, float. I swear I actually leave my body for a split second and look down at us. I see me bent and helpless and I see him kneeling on the floor, his face in my most private areas.

I come back to myself with a snap where I heave and moan and buck and shake.

Again, he doesn't give me any time to get my bearings before he's buried balls deep back inside me. He doesn't play around this time. He fucks me hard and fast, both of us letting out guttural grunts. It's so primal and filthy and hot. Like we're two animals clawing at each other, desperate for release.

He spanks me a little more. "You are so hot, Amanda. You have such a sweet ass and pussy."

"Yes, Professor. Please, harder."

He obliges, slamming into me so hard I don't know how I don't fly across the desk and hit the window. Will I be able to walk after this?

"Can I come, Professor? Please." I can't believe I still have the sense to ask, the ability to form words.

Again, his hand comes down on my ass with a slap. 'Yes." He bites out the word, his control finally starting to show a few cracks.

Everything turns red as I bite the tender flesh of my bottom lip to keep from screaming. My body leaps off the edge and crashes into the burning waves below as the climax rips through me. My eyes roll back into my head and my ass pushes harder against him as my pussy clenches and grabs his long, hard cock.

He stiffens and yanks himself out of me so fast my cunt grasps only air. Hot, wet cum shoots across my ass, dribbling down into the crack of my cheeks. He coats me with his pleasure.

Oh. My. Word.

I can't move, completely glued to his desk. I hear him behind me putting his clothes back in place. He drops a handkerchief on the desk beside me and with weighted arms I clean myself up a bit before letting my skirt fall back down over my ass. I can still feel his cum drying on me though and I like it. I feel like a dirty slut and it's marvelous. I pick my bra and sweater up off the floor and put myself to rights, wincing from the movements. Everything is so sore and sensitive.

I'm really glad I have no classes today. I need to go home and soak in the tub.

Professor Roux clears his throat, the hint of a smirk in his expression. "I want to congratulate you on a very articulate paper. Well done, Alison. It has bumped your grade up considerably. And my special office hours are always open to you if you find you need a little more help."

I grin wide, before bending over and flashing my ass at him one more time as I pick up my bag and pull out my raincoat. "Well, I do have a hard time in your class, Professor. Thank you for the offer and your lessons. I'm sure I'll need further tutoring."

"Excellent."
