Orgasmic Chemistry Ch. 01

*****

Hello there, readers. First, allow me to introduce myself. My name is Alison Schofield, and I'm a 19-year old student in my first year at Durham University. I'm studying for a BSc in Chemistry. Not going to lie, I'm a science geek - always have been. I was one of those introverted, swotty kids, never one to cause trouble, although higher education has brought me out of my shell somewhat...

I'd opted to stay living at home rather than halls of residence, seeing that uni wasn't too far from my parents' house. The cost of tuition fees in the UK being sky-high, I'd recently taken a part-time cleaning job at my old high school. It was only ten hours a week during the evening. It was strange being back at St.Wilfred's after nearly three years. I felt like I was visiting an old friend. The school hadn't changed much, though the classrooms seemed so tiny compared with uni.

The other six cleaners on the team are a decent enough lot to work with. All are over 40, sometimes a little outspoken, especially Marjorie, self-styled leader. She smokes like a factory chimney and comes out with language that would make Russell Brand blush. She has a fiery temper and drinks a lot. They treat me like a kid. I don't mind though. I really need the extra cash right now as I'm desperate for a car.

"Okay we've had a reshuffle," Marjorie said on Monday night. "Alison do you mind moving from the Humanties corridor down to the science block? Some prick put in a complaint saying that the rubbish collection isn't up to scratch down there, so we need an extra person doing the laboratories at the far end."

"Sure, no problem." I replied.

I was actually quite pleased at that. Naturally, the science block was my favourite part of the school when I'd been a student, but not just because science was my favourite subject. I'd had a massive crush on my chemistry teacher Mr. Bibby in Year 11. So what, nothing unusual about that, just like thousands of other students around the world who've fancied a teacher. Mr. Bibby wasn't what one would call a conventional sex-symbol though. A middle-aged, stocky silver-haired guy who didn't suffer fools gladly, and old enough to be my dad. The stereotypical scientist; he always wore a white labcoat, glasses and sensible suit.

Had I admitted to classmates that I fancied him I would've been the laughing stock of the whole school. He wasn't popular among other students, who branded him old-fashioned and strict. There was nothing metrosexual or hipster about Mr. Bibby. You can't choose who you're attracted to though, can you?

I donned my blue tabard and picked up a brush, heading down to SC7, the lab at the far end of the block, which had been Mr. Bibby's room and presumably still was. He'd probably gone home by now anyway, but as I peered through the glass panel in the door, my stomach jumped. Sitting at his desk and checking his laptop was none other than Mr. Bibby himself! For a moment, I couldn't take my eyes off him.

"Get a grip girl," I told myself. "You've moved on now, no excuse for these childish infatuations." 

There were plenty of attractive science teachers at Durham, none of whom currently floated my boat.

He was still wearing the infamous lab coat. He had a manly, chiselled jaw and his grey hair was slightly messy, as though he had just gotten out of bed, this made me think of... well lets not think about that, he's my old teacher, I reminded myself. I plucked up the courage to knock and enter the lab.

"Come in."

"Hello," I mumbled. "I've been transferred down here."

He removed his glasses and smiled. "Alison Schofield?"

I relaxed. "Hello Mr. Bibby."

"How wonderful to see you again! Are you working here? I thought you'd gone to Durham."

I filled him in on my current situation.

"I'm so pleased for you. I always knew you'd do well. In all my years I'd never come across a student with such a knack for chemistry."

"Well I have you to thank for me getting those A* at GCSE," I mumbled. "You always were my favourite teacher."

He seemed to blush slightly. "Anyways, I mustn't get in your way, if you're trying to clean," he muttered, gathering up the papers on his desk.

"Oh do you often work late?"

"Yes. So much marking and lesson planning to sort out these days. But it's not like I need to hurry home soon or anything, so I just stay behind."

My eyes widened. Was that a way of saying he lived alone? I assumed Mr. Bibby was married. He'd worn a wedding ring when he'd taught me as a student. I furtively stole a glance when he wasn't looking - that ring was absent now. I smiled to myself and set to work tidying the lab.

***

That night I lay in bed and masturbated more than I'd done in a long time. I was getting so wet, so hot. I started thinking about a fantasy I had harboured for the past three and a half years and desired so much...being fucked by Mr. Bibby, in the science lab of all places. I started thinking about how it would be...I was in a rush to give myself the release I so desperately needed. I pushed my panties down just a bit, then shoved my right hand down to my pussy.

I used my left hand to push up my nightshirt and play with my breasts, pinching my nipples hard, making me moan with pleasure. My right hand was busy with my cunt, alternately slipping down between my pussy lips and inside my hot, wet core, fucking myself with my fingers, then pulling out to rub my clit. Back and forth, over and over. I was moaning, fantasising about Mr. Bibby pounding me, begging him to fuck me harder and send me climaxing in ecstasy...and him asking me to recite the elements of the Periodic Table at the same time! My old crush had deepened into a raging lust. My God was so hot for my former teacher! I wanted to cum so bad, but I didn't want it to end. 

I was screaming as quietly as I could. Suddenly my orgasm peaked and hit full force. I stopped all movement with my hands momentarily then began again, at first very fast and hard, then slowing as my orgasm began to subside. 

I lay there in the darkness as my breathing slowly returned to normal, a plan forming in my mind. Fantasies were all well and good but at the end of the day they were just that - fantasies. Would I be bold enough to make this dream of mine become a reality? I would be taking a massive risk. If it went in my favour, I would be the happiest girl alive...and not to sound big-headed, but I really wanted to bring some excitement to Mr. Bibby's life too. I figured he was a man who hadn't gotten laid in a long time.

On the other hand, if he didn't welcome my advances I would lose the respect and friendship of my adored teacher. Besides I really didn't want to jeopardise my job. I kept thinking back to how his face had visibly reddened when I'd complimented him. What would the harm be? I was no longer a schoolgirl, but an adult. I was single. I assumed he was now divorced. We wouldn't be breaking any laws. 

I had always been a shy person, never one to take risks or do outrageous things, but I'd made up my mind. I wanted to seduce Mr. Bibby. Tomorrow I was going to put my plan into action...

Orgasmic Chemistry Ch. 02



There were a few raised eyebrows among the cleaners on Tuesday evening when I turned up for work. Instead of my usual jeans and baggy jumper, I was wearing a short pleated black skirt and tighter fitting white top and short denim jacket.

"Bloody hell. You'll catch your death dressed like that, girl!" Marjorie exclaimed, looking at my bare legs before heading outside for a cigarette.

"You've fancied yourself up today haven't you?" another of the cleaners muttered.

"Oh me and some mates were having a party. I didn't have time to get changed again." I lied.

"Parties, cleaning here. When do you find time to fit in your studying then?"

"I manage!"

"Well just don't bend over when you plug in the vacuum cleaner, otherwise you'll end up showing all that your mother gave you!"

I laughed and hurried off to the science block.

Mr. Bibby was at his desk as usual. I felt my face flush; the anticipatory excitement building, my body reacting to the close proximity of him with little shivers that make my arms tremble. 

"Good evening!" I said, with considerably more confidence than last night. "How was your day?"

"A bit stressful," he replied, staring at me and then quickly averting his eyes downwards to his paperwork. "I had a difficult Year 10 class today. Some of those students are a lost cause. I get sick of the backchat and the endless distraction of smartphones."

"Sounds tough. Would you like a cup of tea?"

As cleaners, we had access to the staff room and were allowed to brew ourselves a hot drink before starting work.

"That's very kind but I don't want to trouble you, I know you have a lot of work to do."

"Oh it's no problem Mr. Bibby. I'll be right back!"

"Okay, well a tea with two sugars please. By the way, please call me Brian. No need to be formal these days!"

"Okay...Brian." It felt weird to be calling him by his first name.

I turned and headed out of the lab, my black skirt short enough to give him a pleasant view if he happened to be looking, but subtle as not to look deliberately provocative. As I stole a sneak peek, I noticed his reddening face. 10 out of 10 for observation skills, I thought. So far so good.

A few minutes later I returned with a cuppa.

"Oh thanks, just what I need," he smiled. 

"So...uh, what are your lecturers at Durham like?"

I leaned against a table, on which numerous items of lab equipment were placed. 

"They're a nice lot. The lectures are very enjoyable." I idly ran my fingers down the tube of a Bunsen burner.

"Still using those too?" he added, meaning the burner.

"Not just these." My hand was caressing the burner as though it were a phallic object. "I've graduated to using Teclu and Meker burners now."

"Ah, well sometimes a much hotter flame is needed."

"Mmm, yes, you can get a whole 9 inches of roaring blue hotness." I purred, my hand going up and down the tube in the same way a porn star jerks off a cock. If Bunsen burners could blush, I expect this one would have done.

Mr. Bibby blushed considerably.

"I'd better sweep up this floor. I want your lab to look spotless!"

I set to work on my cleaning duties in silence, whilst Mr. Bibby tried, rather less successfully to concentrate on marking a stack of students' exercise books. Every so often, I caught him making furtive glances at me, whist at the same time I let him catch me staring at him. Feeling myself growing almost uncomfortably wet, I wondered if he was sporting a growing hard-on. This was proving almost too easy - I was starting to worry that something awful was about to happen. Either he'd just get up and go home or that another of the cleaners would turn up and ask me to clean somewhere else.

"Want me to put these beakers on the top shelf?"

"Oh. Er, yes, thanks."

I stood on a stool, at which point it would be impossible for my white panties not to be visible from Mr. Bibby's eye level. I could feel my former chemistry teacher's intense gaze as I carefully arranged the glassware on the high shelf. I finished and stepped down, before turning to face him. He'd stood up and his labcoat was unfastened. Glancing at his crotch, I knew immediately that he was in a state of arousal.

"Would you excuse me just for a moment Alison," he stammered, removing his glasses and placing them in his labcoat pocket. "I uh, need to get something from the prep room."

The prep room was the small storeroom ajoining SC7 lab, where all the chemicals were kept. Stuff that was too dangerous to be kept in classrooms, like hydrochloric acid and the like. Naturally, students were forbidden to enter it. He hurried out of the lab.

"You're not getting away from me this time Brian Bibby," I whispered, following him. Before he could enter the prep room, I'd cornered him. Glancing into his pale blue eyes for a moment, I covered his lips with mine, feeling him tense up as my arms reached round his back. After a few seconds, he relaxed, as if he knew resistance of any kind was futile. I could feel the heat of his body through his blue cotton shirt.

"I've wanted you for a long time Brian," I murmured. "Ever since you taught me in Year 11. Tell me, did you ever suspect that I fancied you?"

"I did," came his breathless reply. "You hid it well, but there were little hints here and there. That anonymous Christmas card for example, that was left on my desk with the nice comments. You hadn't disguised your writing!"

"Ah...well I kept quiet."

"I was flattered. I don't think I'd ever been the object of a student's affections. One usually associated that sort of thing with Mr. Norris the P.E teacher. I heard that a lot of female students and staff were attracted to him."

"Meh far too young and boyish. I am attracted to men, not boys."

A shuddering sigh escaped him as my lips brushed his again. I broke the kiss to open the prep room door. "Is there any space in here to conduct any extra-curricular activities?"

The prep room was a cramped shoebox with metal shelves packed to the brim with glass bottles of different substances. There were boxes of firelighters, gas canisters on the bottom shelves, enough equipment to fill a dozen labs. In the corner was a battered old swivel chair with a makeshift table. No doubt a convenient bolt-hole for a teacher to escape to when the class was getting too rowdy.

Mr. Bibby grabbed my slim hips and motioned me to straddle his lap. "So," he mumbled, rubbing one thumb over the outline of my hardened bra-less nipple through my thin top. "It's...er...been a long time since I was in a situation like this."

"Your wife..."

"I got divorced a year ago."

"I'm sorry."

"Oh it's alright. Mary and I had been leading seperate...and sexless lives for years. It was this job that did it. Too many hours spent behind the desk...we just drifted apart, becoming more like ships that pass in the night. Anyways we parted amicably. My son's grown up and left home ages ago. Mary's met someone else now."

"Oh I'm glad," I whispered. "I would've hated to share."

He leaned in to kiss the exposed skin of my neck; his lips leaving a hot trail from just below my ear to the centre of my throat at the neck of my top. Then he took the lower hem of my top and pushed it up to bare my belly, and then my pert B-cup breasts. Leaning me back, he took one nipple with his lips and I gasped. He was not only willing, but rampant; as he'd confirmed, it had been a long time since this man had got laid.

He sucked, pulling with his lips. At my soft moan, he drew in a shuddering breath. "Touch me," he pleaded hoarsely, bringing my hand to the waistband of his trousers, and then guiding it down to cup the bulge.

I'd never touched a man like this before; but I explored eagerly, desperately, feeling his hard erection through his trousers groping lower to feel his balls. Christ, I was trembling so much with excitment. I couldn't believe this was happening. I was groping my former chemistry teacher's cock! He returned his attention to my breasts and I was so wet I could almost feel myself dripping into my panties.

Well I'm not about to let nerves get the better of me now so without further ado, I unfastened his belt before reaching for his zipper. Mr. Bibby slipped his labcoat off his shoulders.

"No...no, leave that on," I said. 

"You like it?"

"A good scientist always keeps his labcoat on."

He chuckled. "Oh? And why is that?"

"It's the source of your special science powers. Actually I just find men in labcoats hot."

Before he can reply, I kneel in front of him, dragged down the zipper and struggled to get his trousers and y-fronts down. He stood up. 

I'd never done this before, but I pushed aside my anxiety and looked at it from a scientific point of view - after all chemistry was my forte.

"Hmm, time for the practical science experiment to begin," I grinned. I realise how cheesy that must've sounded but to Mr. Bibby that's the same as talking really filthy. He approved.

"If you're going to bring science into it, then we should concentrate on polymerisation!"

"Mmm, all those little molecules linking up to form one huge molecule. so hard, so strong."

I took his hot length in my hand, feeling it, and stroked it up and down as I licked and sucked at the tip. I'm pleased to say that Mr. Bibby was generously endowed; for a man in his mid-fifties his impressive erection would put a younger man to shame. There was truth in that saying - many a fine tune played on an old fiddle. Right now his cock seemed as hard as tungsten, the transition metal with the highest melting point of all the chemical elements.

"Is this your first time Alison?" he asked between sharp breaths

.

I felt myself blush. "Yes," I mumbled.

"Here," he said, moving my unoccupied hand to cup his balls. "Don't be shy. Scientific experimentation can be very rewarding and one must never be afraid to try!"

Gently squeezing his balls, I slowly took his throbbing cock into my mouth. I felt so warm inside knowing that I was able to pleasure Mr. Bibby like this. He moaned as I deep-throated him. I was learning fast. My God, this was amazing...simply amazing.

"Alison," he groaned after what seemed like a long time. "A sexual chemical reaction is about to occur...I'm going to cum."

"Mmff," was all I could utter.

A second later, he came, filling my mouth with his salty load. I savoured the product of this "chemical reaction" before swallowing every drop.

"Ahh...that felt...so good," he sighed, as I gently removed his softening member from my lips. "So...tell me Alison, what's the formula for production of sodium chloride?"

"2Na (solid) + Cl2 (gas) = 2NaCl (solid)." I'd certainly enjoyed more than my daily amount of salt just now.

"100% correct!" he smiled. 

I had a feeling Mr. Bibby's cock would soon return to its tungsten-like hardness if I continued stroking it, but a noise from upstairs snapped us back to reality. Someone was descending the staircase above the science block and it wouldn't be long before our privacy in the prep room would be compromised. As we hurriedly composed ourselves, he turned to me.

"Alison, that was a wonderful experience. It's been so long since I've enjoyed sexual pleasure. I would like to continue this scientific experimentation...I have a feeling you would as well?"

"More than anything Brian. I need you like a flame needs oxygen."

He raised an eyebrow. "In that case, do you think you would be able to come to my house tomorrow after work?"

My heart jumped. "Oh god, yes!"

He adjusted his labcoat and fastened his trousers. "I look forward to it. Oh and just one thing - make sure you revise the Periodic Table..."

Orgasmic Chemistry Ch. 03



My mind had been a complete blur ever since last night. I'd arrived home, somewhat in a trance. Thank God my parents didn't pick up on my strange mood and just assumed I was tired. Not that I was able to get much sleep. I went over and over what had happened in that prep room. I'd performed oral sex on Mr. Bibby. Yes, that really did happen. I'd executed my plan perfectly, and he'd been more than receptive. Just the thought of his tungsten-hard cock had my cheeks reddening and my pussy moistening. Before very long I was masturbating furiously once more. He wanted me and I wanted him. Was I going to be bold enough to go "all the way?"

"Well you've sucked his cock, so there's no going back now!" I told myself.

What would tomorrow bring?

***

"Where the hell did you disappear to last night, Alison?" Marjorie exclaimed, as I arrived at the cleaner's room, trying my best to act completely normal.

"What do you mean?"

"Karen went looking for you down the science corridor. She wanted you to help her carry some sacks of trash from upstairs. Only when she arrived, she couldn't find you anywhere. She looked in all the science labs."

"Oh shit," I thought, frantically racking my brain for an excuse.

"Hey, maybe she's a secret smoker!" Karen interrupted, walking into the room."

"Just had a bit of a headache last night, so I went to the toilet then just popped outside for some fresh air. I'm sorry, I didn't realise you wanted me."

"No worries," Marjorie smiled, playfully knocking my arm. "I'll let you off this time. Anyways you must be doing a bloody good job of cleaning those labs because a member of the teaching staff came in before and was praising you to the skies."

"Oh?" My mouth suddenly went as dry as the Sahara. I quickly sipped a mouthful of coffee.

"Yeah. Old silver-sideburns himself - Mr. Bibby. You probably know him, he teaches chemistry."

Ever wished you could just shut your eyes and teleport away somewhere? At that moment I really wanted out of there.

"Um, yes I know him. He once taught me." My stomach was alive with butterflies.

"Heh, he's normally such a grumpypants, but he was all smiles just now. Just goes to show, people aren't what they seem. Anyways keep up the good work!"

"I will, yes." I murmured.

I headed down the corridor to room SC7. "Oh Brian, you've more than earned a special treat now," I smirked.

Tonight, he wasn't sat at his desk but standing up looking at the Periodic Table that was pinned to the wall. His arms were behind his back and he was anxiously twiddling his thumbs. Damn, I forgot to revise it, like he asked. Oh well...

I entered the lab and closed the door. Mr. Bibby spun round quickly.

"Alison..." the expression on his face immediately became one of excitement.

"Brian.." I locked the door and walked over to where he was standing.

"I didn't get an ounce of revision done last night, so I guess you'll have to give me detention. Thanks for the complimenting me to the other cleaners by the way." I set my hand on his leg, feeling his firm flesh beneath his sensible dark grey trousers, and looked up at his face. His blue eyes focused on me with such an intensity. "Besides, a scientific experiment is best performed in a laboratory."

He blinked. "What you mean...?"

"I can't wait. I need you now. Right here. I want you."

He glanced round the lab cautiously. It had three windows which overlooked the playing fields so no chance of prying eyes, save for the glass panel in the door of course.

"I want you too," he replied softly. "About last night...let me just say that you awakened long-dormant sensations in me. I feel like a new bloke."

"I bet you could barely concentrate on teaching classes today," I added.

"No I couldn't, it was difficult! I confess during lunchtime I couldn't last any longer and shut myself away in the prep room to jack off for a bit. That's the effect you've had on me Alison. I've never got so many hard-ons in just one day!"

Shock silenced me. As I gripped the side of the desk, I imagined myself a net to catch all the butterflies in my stomach. I couldn't believe he was actually going to ravish me right there in his science lab. The feeling of accomplishment filled me with euphoria.

The lab was a bit chilly but I didn't care, we'd soon be warming things up - an exothermic reaction of sorts. Mr. Bibby scooped me up and planted my arse on the desk top. I grabbed the lapels of his white labcoat, pulling him closer. When he lifted my chin with a touch of his index finger, my lips were almost level with his. He kissed me gently, just a brush of his lips on mine, and heat suffused my lips and flowed down to warm my whole body.

"Oh Brian...Oh God..."

I reached up and unfastened his red striped tie and it dropped to the floor. Then I ran my fingers through his silvery hair. I took in his face; lips that now formed a smile as he watched me watch him. Mr. Bibby kissed me and I parted my lips to let him in. The heat of his mouth and his probing tongue sent shivers through my body and I shifted closer to him to feel the heat of his body against mine. I breathed in the faint masculine scent of his aftershave and listened to the sound of his breathing. Mr. Bibby pulled away from my lips and leaned in to kiss my neck. His mouth was hot, demanding, kissing under my jaw, and I felt the heat of his breath on my skin. He carefully lifted up my top to expose my belly and breasts, and then moved away just long enough to pull it off over my head.

I felt suddenly exposed and chilled by the air, but I fully trusted him, and when he leant down to kiss my belly button, any chill was forgotten. He kissed up my belly and each kiss left my sensitive skin tingling. When his tongue finally touched one hardened nipple, I drew in a gasp. I could feel this forever and I wanted nothing more than more of him. I arched my back and clutched at his hair to pull him closer. He gave my breasts his full attention: cupping each small mound with his hand as he sucked and gently bit my nipples. I was getting so wet I was afraid it was already soaking through my panties.

"Mmm, so Alison, what's the chemical symbol for Hydrogen?" he murmured.

He'd gone back to the chemistry talk again. I don't know why but it just turned me on even more when he switched to science teacher mode. 

"Easy, it's H," I replied. "God, you're making me so wet..."

"Mmm, how about Meitnerium?"

"Uh...Mt?" My eyes closed, but I roused myself enough to reach for him. It was a stretch to get my hand to the button of his trousers, but he paused to help me. With one hand, he guided my fingers in cupping the massive bulge that was already straining against his clothing. My fingers trembled with excitement as I touched his "laboratory equipment" again.

"N-not bad for someone who hasn't revised!"

With one hand, Mr. Bibby unbuttoned his trousers and slowly guided my fingers inside. My fingertips brushed the wiry curls of his pubic hair, and then I cupped him in my hand and stroked his cock, his hand still subtly guiding mine. Then I heard gasps that he tried to hold back. 

"I want to make you come," I said, the words popping out before I can think.

He groaned, a low sound that he obviously tried but failed to suppress, and stilled my hand. 

"Alison," he whispered, his lips brushing my cheek, "do you want me to do this?"

My eyes widened and I smiled, mentally jumping up and down with glee. "More than anything!"

Mr. Bibby's face flooded with colour. I wasn't sure whether it was embarrassment or arousal or a mix of both. He slowly ran his hands up my thigh, under my skirt. It tickled and I giggled. He kissed the inside of my thighs. I raised my bottom so that he could pull my panties down my legs and onto the floor. For the first time I felt awkward, almost nervous. The butterflies returned. Tender kisses and caresses soothed my nerves. 

He murmured, "If you want to stop at any time, tell me. I won't push you. I promise."

Reassured, I smiled. "Keep going. We've hardly covered any of the Periodic Table yet!"

Mr. Bibby moved the tip of his tongue to my clitoris. I jumped and willed him to move faster. At first his tongue explored my wet folds, but he replaced his tongue with gentle fingers that probed and rubbed and finally penetrated me. My wetness was dripping down my butt crack and he rubbed it around with his fingers. The sensation made me squirm and I placed my feet on his shoulders, and when he finally sucked on my clit, I nearly lifted myself up to meet his tongue.

"More elements," he murmured between sucking. "Let me hear you recite as many that you can think of!"

I couldn't cheat by glancing at the table on the wall because he'd blocked the view. "Ahh...Fluorine, Chlorine, Bromine...I-Iodine..." I struggled to speak. "Ass...Astatine. Helium, Neon...Argon...Krypton...Xenon...oh, Radon!"

His reply was cupping the cheeks of my bottom in his hands and pulsing his tongue steadily as he sucked. I cried out and writhed in his grip; my toes pointed and my whole body stiffened as he shook, but he held me and didn't let up on my clit. The feeling was so intense I almost screamed; before remembering that I had to keep the noise down. I was biting my lip as I orgasmed.

Mr Bibby's face was flushed and damp and his expression was one of pure longing. 

"Alison...I want you so much..."

He fumbled with his trousers and underwear before finally freeing his erection. My God, I was hungry for that cock.

"Is this an atomic bond?" I teased.

"It's certainly going to be a strong bond!" he replied, lifting me. He pulled me closer and guided his engorged cock between my lips. "This might hurt," he whispered and pushed up into me.

"Ahhh!" I gasped, more from surprise than the stretching sensation.

"Are you alright?" he said, wrapping one arm around me and holding me close. I gave my answer by kissing him. He insinuated his hand between our bodies and fingered my clit as he began to move inside me. Holy shit, those fingers...he knew exactly how to pleasure me for maximum effect! For a moment I thought of all those sexless years he'd endured with his ex-wife. Here was a skilled man indeed and not just in science.

"Ohh...oh Brian!" I sighed. He stroked me with wet, slippery fingers and thrust steadily up into me. The combination awakened something within me and I sat up straight on the desk, clutching at the sides of his labcoat. My heels dug into his back and I tried to speak, but I couldn't form words. I couldn't think of any more chemical elements either. This was it, everything I had ever fantasised about, here I was at last, being fucked to perfection by my former chemistry teacher who deserved a dozen A* for his efforts! It was better than I ever could have imagined. I let my hands wander across the desk, my fingers brushing against a pair of gas taps.

Mr. Bibby's large cock filled me completely, stretching my walls to the limit. He was groaning and pounding me like crazy. I swear if anyone had been outside in the corridor they would've been able to hear us at once.

"Alison, come," he whispered in my ear, and I cried out. "Come for me, release those subatomic particles," he pleaded, and I did, my head falling back, my whole body shaking and clenching with the intensity of my orgasm. He followed immediately; in an instant our scientific experiment reached its conclusion and I was filled to the brim with his warm seed...

We lay there on the desk for what seemed like a long time. Eventually, Mr. Bibby gently withdrew his softening member from me.

"Well? Did you enjoy that special science experiment Alison? Because I certainly did!"

Rather flushed and giddy, I embraced him. "Yes!"

There was so chemical formula that could describe what we'd just enjoyed. In his arms, I just felt safe and warm and satisfied, and that truly was the best feeling in the universe.

The End
