Chemistry with Mr. Sullin

Warning:

I do NOT condone teacher/students relationships. This is all fictional. The main character is 100% 18 in this story.

"I'm passing out the grades now", the hushed groans and nervous chatter from the students around me made me drop my head in shame.

My thoughts were met with certainty when a look of disappointment flashes in Mr Sullin's eyes brought my shoulders down and I cast my eyes down to the 73% written on the top right of the test paper. Bright and bold in red. I couldn't possibly miss it.

"Talk to me after class Belle", he whispered and I quickly nodded my head. God. I'd been doing so well in chemistry this year. I did my textbook questions everyday, listened attentively in class when he went through study material.

What happened. And even though I know the organic chemistry topic was hard, I still was disappointed in myself. The 73% was ingrained into my brain and I couldn't stop thinking about it.

I look towards my friends as they debated about their marks, "how'd you go Belle?" Ryan asks me, he tries to be polite with his neat smile and offering his test to show me his own mark. But I know he just wants to see if he had finally topped the class this time.

"Class dismissed", Mr Sullin's shout made me let out a breath of relief as I pretend to be distracted with packing up my notes and pens and ignore Ryan standing behind me.

When the last of the students rush out to lunch, I stand and wait for my chemistry teacher who stands there and watches me. I knew my test score was disappointing.

"What happened Bella?" His deep voice makes tears prickle at the back of my eyes and my throat catches a small whimper that wants to form.

"I don't know. I practised so many questions the night before", and perhaps it was the fact that my fists were clenched so hard I drew blood or the stress of the situation that finally made me crack. Sobs starting to fill the empty classroom as I stood there trying to find an appropriate excuse to my lacking result.

But I couldn't think of one. I just messed up.

And when thick arms reach around to hug my shaking body, I couldn't help but break down. I fisted Mr Sullin's thick black winter coat and cried so hard I knew my eyes had turned a blood shot red. His hand reached up to pat my head, "I do provide additional credit", he says looking down at me

"Would I need to submit an extra assignment?" I asked him with desperation. I'd never heard of any other students being given this opportunity like this, maybe he thought I deserved a second chance.

Mr Sullin hummed in response and walked over to the door and pulled down the blinds. He turned to look at me and I could hear the click of the door closing behind his back. His focused gaze at me suddenly no longer felt comforting, it made the hairs on the back of my neck stand and my tears dried up.

"Turn around Belle", he instructed, I could hear his footsteps as I turned to stare out the window. The chemistry lab was upstairs, meaning that no other students or teachers would be up here during lunch.

His rough hands on my shoulders made me jump, I clenched my teeth and could feel sweat trickling down my neck.

What extra credit did Mr Sullin mean.

"What chemical reagent can be used to differentiate carboxylic acids and aldehydes?" He follows his question up with a finger sliding into the front of my senior blazer and pulling it off my slim shoulders. The cold air of the science lab hits me as a layer of my protection against this man is removed.

"Acidified dichromate?" I speak in whimpers and sob when his hand spans down to my ass and spanks it. I jump away from his muscled body but his arm pulls me back to his chest.

"Wrong. Tollen's reagent", he snips into my ear and rubs my sore flesh before bending my over the bench. I can still see through the window and notice students running about and eating their lunch as if everything was completely normal. As if my chemistry teacher wasn't assaulting me, and I was too scared to object.

"Please Mr Sullin, this is wrong", I try to push back at him but he presses his covered crotch into my back and his hardened length makes me squirm.

"Why can't carbohydrates dissolve in water?" his next question is punctuated by a hand playing with the dainty buttons of my school shirt. Each second that I take to think of an answer, he uses the opportunity to undo one and my heart thumps loudly against the wooden bench I'm pressed against.

"Uhh because their large molecule means water can't form enough hydrogen bonds" I try to sound more confident this time because I knew that I had practised this question a million times but the feeling of the veins of his arm and hand pressing against my breasts and stomach made me cry.

And when he harshly yanks my bra down to fist my small breasts within his palm, I let out a loud sob. A tingling sensation builds in between my thighs and I press then together to relieve the tension.

His fingers press and play with my nipples painfully before he takes his left hand and adds another smack to my ass cheek. I whimper.

"You need to mention the non-polar hydrocarbon chain", he mutters before directing his hand even lower to meet the top of my school skirt.

And in that moment I regretted begging my mother to have it shortened at the beginning of the year.

"You wear such a short little skirt, do you know how long I spend looking at your legs everyday Belle", and this time he unbuttons and pulls down my bottoms until the sound of it hitting the floor has me silently crying. The feeling of his dirty hands running up and down my thighs and into the crevice of my sex has my blood thumping loudly in my ear.

Suddenly the sound of heavy foot steps echo down the hall way and I knew someone was coming. Oh God. If they found me half naked under Mr Sullin, I could get suspended. I was half way into year 12, and now that I'm 18 my parents could legally kick me out of the house for it.

Mr Sullin reaches down to grab my fallen uniform and pulls me into the small seperate room at the back of the classroom, meant to store chemicals and practical equipment.

"Hello principal Smith, what can I do for you?" The casual tone in Mr Sullin's voice as he makes conversation with our principal has me shying into the back of the small cupboard that he had shoved me into.

They continue to converse about new school regulations and time schedules, but when Mr Sullin reaches into the back of the shelf and brings out a small bottle of liquid, I cock my head to the side in confusion.

What is he doing?

My confusion is answered quickly when he smears the mysterious liquid on his fingers and shows the principal a tight smile before reaching his arm down into my damp panties and rubbing it all over my little slit and hole.

I squirm against him but swiftly shove my hands over my mouth to stop sounds from escaping. And extremely quickly, a burning ache tingles between my thighs and I know he had smeared some sort of aphrodisiac onto me.

Oh God. I whimper into my palm and crouch into the small corner of the room to press the heel of my shoe into my vagina to relieve the fire. I can feel the smirk growing across Mr Sullin's face as his glances over and see me succumbing to the pleasure he had forced onto me.

In desperation, one of my fingers reaches and pulls the side of my underwear aside to play with the slick that had built up. Strands of clear liquid stick between my thighs and sex as I start to stroke my labia, and spread my lips apart to rub away the aching pain that had built up.

I close my eyes and try to block out the two teachers that stand only a couple of meters away as I try to chase my orgasm. But the loud squelch of my pleasure had become quite obvious now that my entire hand was coated and I had to stop when a warning glance from Mr Sullin worried me that we had been caught.

After a few more moments of silence, the click of the door made me let out a sight of relief as the principal had left the room. Without a second to waste, my teacher yanked me out of the dark cupboard and shoved me onto his desk. His papers and pens falling to the ground as he pulls my thighs apart to inspect the wetness that had accumulated.

"You're a horny little thing now aren't you?", maybe it was because before now, I had never looked this closely at his face but the strong jawline and dark eyes only made me want to whimper. But not in fear.

But I told myself it was because of the drug he had shoved into my vagina. Because I couldn't possibly be aroused by my own teacher, he was nearly in his early 50s. His wrinkled hands painted the years he had lived through and despite that, them wondering towards my nipples to yank made me silently scream.

My entire sex, all holes and weeping slit was exposed to this old man as he parted my labia like a flower that was about to get its petals ripped off.

"I want you to beg me to fuck your tight little hole", he grits out before smacking his large hand down onto my pussy. The harsh sting made me scream but the gush of liquids told him I enjoyed it more than I let on.

Another smack has me attempting to close my legs which he smacks his lips in annoyance to before pulling my small body down to the edge of the table. My ass barely hanging off the edge and his hardened cock, through his pants, rubbing against me.

"You want a better grade so your parents don't kick your 18 ass out onto the streets? Start fucking begging", he growls into my ear and fists my hair as a warning to do as he says.

Snot builds up in my nose and my mouth goes dry, "please Mr Sullin, fuck me", I whisper.

Another smack and tug at my hair has me crying. He wasn't satisfied.

"Please. I want your cock inside me. I want you to fuck my tight little hole", I try to push my crotch against his to make it seem like I was trying my best.

"That's abit better I suppose. But I want to hear your desperation. I want you to mean it, you little slut".

"Please fuck me until I'm full of your cum, please stab my cunt with your cock until my virginity is no where to be found", I let out but I sob soon follows when I hear his belt unbuckling.

No. No. Please. I didn't mean that.

"Well. You asked for it", he chuckles and his dick stands erected, its mushroom tip touching the base of his stomach and his pre-cum smeared around.

The veins travelling up the base of his manhood had me hyperventilating as I sized up the beast that would try to enter me.

"Please no. That won't fit. Please. I'm a virgin. I've never done this before", I try to shield my pussy with my hands but he swats them away and presses his head into my labia.

"I want you to be quiet Bella", he warns me before pushing forward.

I gasp when his cock suddenly pushes itself past the small ring of muscle of my hole. I can feel my walls hugging him tightly and he groans.

I sob and push my hands at his chest, "please pull out. You need to wear a condom", as he rests his dick against the membrane of my virginity.

But he ignores me and with a sudden jolt of his hips, the base of his cock meets my crotch and he bottomed out into me. All I can feel is pain, it feels like he teared my flesh apart as I pulse around him.

Each of his thrusts is punctuated with a groan and whimper from me as I feel his manhood bumping into the end of my tunnel. The sensitive spot that he keeps on barrelling into within me has me moaning into his ear despite the lingering ache of his violent de-flowering.

"Please please pull out", I try to beg him but he ignores my voice completely. Completely focused on the clenching organ between my legs, his brows furrow and he brings his hands under my ass to pull me even closer to his hard thrusts.

The slaps of our skin and sound of my slick resonate throughout the classroom and I knew I could never stand in this room and not think about Mr Sullin's thick shaft that's making me cry out in pleasure.

I can feel the added wetness of my virgin blood coating his dick, and the red liquid dripping off his balls has me meeting his shoves with a force of my own.

I need to cum so fucking bad.

Loud gasps and wails edge him on as he reaches down to my clit and rubs at it harshly. This makes me bite into his shoulder to stop a defeating scream that would definitely have people downstairs aware of the debauchery happening in this very classroom. Between a freshly turned 18 year old student and her chemistry teacher.

The depravity of the situation has me quickly clamping my soaked muscles around his plunging member as I cum for the first time. My lips open as I try to keep my cries silent but failing. Winded gasps and my chest attempting to pump enough air into my lungs are all I could focus on before Mr Sullin resumed his fucking.

"I want my cum soaking into every crevice of your cunt, I want to ruin you for any other man", he shouts into my face as he angles his last thrust and pushes against my cervix. His comment has my eyes opened wide, fuck, he came in me without a condom.

The warmth of his cum fills me and small drops of it drip out of my stretched hole when he pulls out. His desk no longer was neat and orderly like how he usually kept it. Instead, a mix of our sex fluids had formed a tiny puddle under my ass, it's crack now moist from our activities. And my shaking naked body lied on top of all his papers; the written assignments of students and printed worksheets now crumpled from his rough fucking.

After, Mr Sullin instructed me to put my clothes back on and to meet him in the parking lot after school.

I sit over a toilet as student's shouts down the hallway to try to make it to their lesson after lunch ended has me crying softly into my hands.

What have I done. I let my teacher fuck me and now his cum was slowly dripping out and into the toilet bowel.

Every drip had me cringing as I knew that I was at high risk of becoming pregnant. The consequences of this were even worse than getting a low B on a test.

My vagina still stung and ached from its first time having sex, and Mr Sullin wasn't exactly gentle or comforting. And the thought of doing it again with him has me panicking.

I reach down and touch the tender flesh, it was my first time doing anything at all today. My first organism, my first time having sex and my first time being fucked.

All with him; my chemistry teacher.

I curl my fingers into my well lubricated hole and the barrier that I once felt was no longer there, it had been removed by Mr Sullin. He had de-flowered my virgin cunt.

And despite the pleasure I had from fingering myself in the school toilets, I couldn't reach the same depths that his cock had. Couldn't reach the same crash of pleasure as my laboured breaths and whimpers filled the stall, but I didn't feel the same ache. An ache that I only felt with him.

He was right. He had ruined me. And soon my second organism crashes down but I feel empty, and my walls clamped down on my thin fingers that left me unsatisfied.
