-------

Chemistry was the bane of your existence. You had never struggled so much with a subject. You had completed three general chemistry classes, two genchem labs, three organic chemistry classes, two ochem labs, and now you were taking biochem and a biochem lab. But despite all of your academic background, you still didn't have the slightest iota of understanding.

Even so, you couldn't stop yourself from looking forward to the weekly lab. You hated having to change from shorts into pants in the tiny bathroom stalls (no way in hell were you walking all the way across campus in high-humidity weather wearing pants). You hated the red line on your forehead from the goggles. You hated having to stand for 2+ hours because the lab wasn't equipped with stools. You hated chemistry in general. But you loved seeing the uber attractive GA, Spencer Reid.

More often than not, you spaced out during his pre-lab instructions. You were too busy focusing on anything about him that wasn't the jargon coming from his lips. Your poor lab partner always ended up having to re-explain the procedure. But today, that wasn't an option. Your lab partner had a wedding to attend today and, instead of being in your usual lab session, had opted to join yesterday’s lab session, leaving you all by your lonesome. Initially, you had cursed their name to hell and back for forsaking you like this, but, after Spencer offered to give you all the extra help you needed, you were suddenly exceedingly happy that your partner wasn't here.

You could see the scathing looks directed at you by some of the other girls in class. Of course you weren't the only one who had immediately taken a liking to the young GA. Only a blind person wouldn't be able to see how good looking he was. And the girls in your class were definitely not blind. You couldn't help but feel a bit smug that you would be getting his extra attention and not them.

Spencer, unbeknownst to you, was having similar thoughts and was mentally extending his gratitude to your absent lab partner. He was more than aware of the implications of coming onto a student, especially since as a GA he was in a position above you. But he wanted to be above you in the literal sense, and it was beginning to cause him to question his morals. You were the same age, so how bad could it really be? He’d noticed your frequent glances at him and reveled in the fact that you couldn't keep your eyes off of him.

During the course of the lab, Spencer was essentially your replacement lab partner. In an attempt to not show his blatant favoritism, he didn't actually guide you through the lab and instead just followed your instructions, such as pouring out chemicals into the waste bucket and washing beakers. Labs were lengthy enough with two people working together, and although Spencer would like to keep you all to himself past the time the others had already left, he remembered how miserable it was to have to stay late.

But even with his help, you still found yourself to be the last one. And not only were you the last one, but you weren’t even close to being done. Since there wasn't anyone to tell him otherwise, Spencer took pity on you and gave you far more help than he probably should have. But if he was being totally honest with himself, he just wanted an excuse to be close to you. Even though there was more than enough room at the bench, he still stood near enough that your arms occasionally brushed. Every time you handed him something he made sure his fingers met yours. And when you asked for his input about the data report? That was his favorite. His stature gave him the perfect excuse to lean down under the guise of seeing better, but he always bent down lower than he really needed to, just to have his face right next to yours and give him a front row seat to your flustered expression.

It took all of your willpower to keep your head out of the gutter. You were trying in vain to rationalize his actions. Like maybe he just didn't realize how close he was actually standing to you, and you were definitely overthinking the hand-to-hand contact, and maybe he just didn't have his contacts in and that’s why he was leaning so close. But try as you might, it wasn't enough to prevent you from getting severely distracted by the handsome GA, and getting severely distracted in a lab was typically advised against. In your flustered state, you grabbed the wrong pipette, and Spencer, just as distracted as you, didn't notice and was unable to stop the impending mistake.

Pipettes were made to measure precisely, but they don't all measure the same. So you'd royally fucked up the experiment by adding 10x the amount you were supposed to. And thanks to the stir plate the beaker was on, the solution was rapidly mixed together.

“Is it supposed to smell like that?” you asked nervously. It was a sharp, acrid smell, one you surely would have noticed earlier when your classmates were on this step.

Spencer was abruptly snapped out of his thoughts and looked at the beaker, the stir bar still spinning wildly within. He noticed the smell you were speaking of and instantly pulled you backwards. “No, no it's not. Don't breathe it in.”

He covered the lower half of his face with his elbow and grabbed the beaker from the stir plate with his other hand. He made his way to the fume hood as quickly as he could and shut the beaker within. But it was too late. You’d both inhaled the gas already, and, thanks to your biology major, you were more than aware of how sensitive the lining of the lungs is. It was literally designed to allow for gaseous exchange. Whatever you’d accidentally created was already making its way throughout your body.

As Spencer was making his way back over to you, he noticed that he was beginning to feel incredibly hot, and his breathing was becoming shallower. It was shortly after the onset of those systems that he realized his pants were progressively getting tighter in the crotch. This could not be happening. What in god’s name had you created? He was practically panting when he got back to your workbench and found you in a similar state.

You immediately began to spew apologies, but Spencer wasn't listening. No, he was far too focused on keeping his hands at his sides and not on you. He held a hand up to stop you rambling and swallowed harshly, trying to get himself under control. “It was an accident. Are you feeling okay?”

“Feel like I have a fever and my heart is beating way faster than it was a minute ago.” Your panties were also becoming wetter by the second but he didn't need to know that.

Spencer’s normally sharp mind was in a flurry. Even though you hadn't told him in words, your body betrayed the fact that you were just as aroused as he was. The subtle rubbing of your thighs together was a dead giveaway. You had your back to him, hands braced against the edge of your workbench. If Spencer was thinking straight, he never would have acted on his inappropriate thoughts; but he wasn't thinking straight. He closed the distance between the two of you, leaving no space between your bodies. He placed his hands on either side of yours, effectively caging you in his arms. Your breath hitched at the intimate position you found yourself in.

“I know you feel what I do,” he said, slightly pushing his hips into yours, his hard cock straining against its confines. “We can help each other out. Or, you could tell me to fuck off and I’ll let go as soon as you tell me to. Whatever we do or don't do, it's your choice. Just tell me what you want.” His voice was breathy and high-pitched by the end, and his self control was splintering by the second.

You adjusted your stance, the movement causing you to brush against Spencer’s front. He gasped and his hands flew to your hips, gripping them tightly and holding you in place tightly against him. “Don't-,” he panted. “Don't do that. Not until you answer me. I won't be able to stop if-”

You cut him off. “I don't want you to stop.”

And that was it. Throwing caution to the wind, Spencer spun you around to face him. “Are you sure?”

You surged forward to kiss him. Your goggles clacked together and you pulled away with a giggle. “Very sure,” you said, pulling your goggles off. Spencer followed suit.

He nodded. “Ok. Ok.” He sounded like he was trying to reassure himself that this was really happening. Despite his nearly painful erection, he tried to be as gentle as he could with you. He reconnected your lips in a tentative kiss as he wrapped his arms around your waist, but with the strange gas the reaction produced was still in the air and still wreaking havoc on both of you, it didn't stay gentle for long. What had started as a hesitant kiss devolved into a harsh collision of teeth and tongue.

Spencer’s hands migrated from your hips to your ass, pulling you flush against him. He couldn't stop the involuntary thrust of his own hips, desperately seeking friction. His mouth separated from yours as he dragged his lips down your jaw and reattached to your neck, sucking harshly and surely leaving dark marks all along the column of your throat.

He lowered his hands just enough for his fingertips to brush the back of your thighs, squeezing twice in a silent indication to jump. You tightened your grip around his shoulders to give you leverage. He hoisted you up to sit on the countertop and pushed your shirt above your breasts. You removed it entirely to give him full access. He groaned as he took in the sight of you breathless before him. “You're so pretty for me,” he praised before roughly pulling the cups of your bra down, exposing your nipples to the chill air of the lab, a stark contrast to the heat that had spread throughout your body so rapidly. He latched his lips to the newly exposed skin, his hand groping the other one. You reached behind your back to unlatch your bra and tossed it aside.

You threaded your fingers through his hair and tugged, pulling him off of your chest and back up to your lips. Both of your patiences were wearing thin, and neither of you could get the other undressed fast enough. You tugged on his tie and it soon joined your bra and shirt on the floor. You continued to unbutton his dress shirt as his eager hands groped at every part of you they could reach. When you’d finally gotten his dress shirt open, he didn't even give you the time to admire his physique and instead pulled you from the counter top to stand again.

He tugged on the waistband of your pants and pushed them down, leaving you to kick the material off of your feet. He quickly spun you around and placed a hand between your shoulder blades, urging you to bend over. You did as he wanted and felt his hands caress and grope your behind before his fingers hooked under the waistband of your panties and pulled them down just enough to expose your cunt to his hungry eyes. He groaned at the sight. “You're so wet baby. All for me.”

Spencer dropped to his knees behind you and immediately pressed his face between your legs. You squealed at the sudden contact, his tongue doing wonders for the built up need you had for him. He licked a broad stripe up your pussy before alternating between suckling and licking the sensitive flesh. Your whines and whimpers only spurred him on further, becoming more vigorous with his ministrations. The increased intensity had you gasping for breath and calling his name. “That’s right, angel. Who's making you feel this good? Hm? Whose face are you going to cum all over?”

“Yours! Please, Spencer, don't stop!”

He chuckled briefly before resuming his eager lapping at your core. He hummed against you in affirmation, pushing you closer and closer to the edge until the pleasure was just too much to bear. You came with a cry of his name, and he didn't stop until you were begging for a reprieve.

The unnatural heat that had spread throughout your body upon inhalation of the fumes was finally dissipating, leaving you with the normal flush one would expect afterwards. But Spencer was nowhere near recovered, and he had no intentions of letting you go until he was satisfied. He stood from his place on the floor and made quick work of his belt, only pushing his pants low enough to free his aching cock, dripping with precum. He stroked himself as he spoke. “We’re not done yet, angel. Not by a long shot. Not until your sweet cunt is dripping with me.”

His words sent heat racing to your core. Who needs aphrodisiac fumes when Spencer can talk to you like that.

He swiped the tip of his cock through your folds a few times before lining his tip up with your opening. He pressed forward and groaned at the sensation of you squeezing around him so deliciously. He pushed further and further until he bottomed out. His jaw fell slack in complete and utter bliss. “Oh, you feel so good, baby. Can I move? Please, please, I can’t wait any longer,” he begged. You’d let him do anything if he begged you as prettily as he did then.

You hummed in assent, and he wasted no time in pulling out until just the head of his cock remained buried in you and then thrusting back in. You let out a loud moan, already completely overwhelmed with just how good he felt inside of you. The more he thrusted, the needier he got and the more that unnatural heat in his chest smoldered. His hands gripped your hips tightly and he pulled you back to meet him with every thrust into your sopping cunt.

“I'll bet none of those silly little frat boys can make you feel like this, huh. I’ll bet they always leave you unsatisfied. But you're gonna cum for me again, right? You can do that f’me, can't you? Be my good girl and cum all over my cock.”

The sound of skin slapping against skin increased in tempo as he chased his high, wanting nothing more than to feel you clench around him as he emptied himself inside of you. You moaned shamelessly, the deep and harsh thrusts of cock almost too much to bear. You couldn't speak even if you wanted to. The only word you were capable of uttering was his name.

His grunts were turning into whines the closer he got to his impending orgasm. “Cum with me, baby. C’mon, you can do it,” he said, moving one of his hands down to rub circles on your clit. That was all it took to have you creaming around his cock, your orgasm triggering his. The moan that came from him was pure sin as he spilled himself inside your cunt, just as he had promised. He collapsed on top of you, cock softening within you as it twitched with every flutter of your walls around him. When you had both sufficiently caught your breath, he stood back upon and gently pulled himself out of you. You winced at the loss of contact, still extremely sensitive. You pushed yourself off of the workbench and turned to see Spencer tucking himself back into his pants. It was then that you realized you were stark naked in a university laboratory. You saw your panties lying near your feet and you hastily put them back on, followed shortly after by the rest of your clothing, which Spencer helped pick up from the floor where they had been unceremoniously discarded.

“Would you want to get coffee with me sometime?” Spencer asked suddenly, the words spoken so fast they nearly blended together.

You were taken aback. You had expected him to want to pretend this never happened but here was asking you on a date. You grinned, a prominent blush on your face as you accepted his offer.

He beamed, a broad smile overtaking his face. “Great! I’ll pick you up Saturday morning?”

“Yeah, sounds good. I think I can safely assume it won't be the coffee shop on campus?”

“Even though we're the same age, you're still one of my students. So until you finish this course…” he trailed off.

You grabbed his tie and pulled him closer to you until your faces were a hairsbreadth apart. “I’m completely fine with being your dirty little secret until then as long as you fuck me like that again.”

Hey I know you’ve probably already been asked this but what type of chemistry do you use for breaking bread like biochem and where did you learn this or have any book recommendations to pick it up? Also ty in advance I love your writing!!💕💕

oh my fucking god. oh my god. buddy. buddy you have made my fucking LIFE ASKING THIS OH GOD

So like, most of the chemistry I've used so far has just been Genchem and O Chem(with a wee few modifications to make it believable as a Cybertronian discipline, like Transformium being able to hold 4 bonds like Carbon but preferentially forming bonds w metals and needing an EMP pulse to interact w more electronegative atoms) I may wind up needing to get into a bit of Inorganic chemistry, but that's probably fewer and further in between. If you want a better handle on the stuff I'm writing or if you just want to learn more in general, then I'd recommend giving yourself a lil crash course in Genchem and then delving into O chem a bit more extensively (protip : you need WAY less Genchem then you'd think to fully understand O chem. God I wish someone had told me this 5 years ago. If you search "Genchem for non majors", you'll probably learn enough that way.)

THAT SAID : here's a chaotic, not really in any order list of the books/youtube channels/etc that I've directly used/am using for this fic.

Books :

Caveman Chemistry, Kevin R Dunn - Alot of hands-on old timey historical chemistry lessons w detailed instructions on how to complete them.(YOU GET TO MAKE YOUR OWN ASPIRIN AND DRAIN CLEANER!) Delivered with a delightfully occult bend.

Back To basics,(Reader's Digest) - Survivalist homesteading bible. Not strictly chemistry but has alot of earthy hippy ways of generating energy( biofuels my beloved)

An Introduction to Fire Dynamics, Dougal Drysdale - Honestly this, and any other firefighting manuals are worth their weight in gold for figuring out how to not set yourself and your neighborhood on fire while playing with, well, fire. Trying to look this info up online is like playing russian roulette with intentional misinformation and your fbi guy.

(there's another book I have that's even more detailed but I can't find it right now or remember the name. I'll update this list when I can!)

Organic Chemistry, John Mcmurray 8th edition : generic but good college O chem textbook. You can search around and find free versions to download relatively easily.

The Organic Chem Lab Survival Manual, James W Zubrick - Also a very good way to learn how to not set yourself and your neighborhood on fire when playing with glassware/gases. Very in-depth instructions on setting up and using lab equipment without breaking anything or your brain. Has a fuckton of pictures. Author has a massive sense of humor and makes this heavy subject easy to read. Again, easy to download/find in archives

Unfortunately I do not have any recommendations for Genchem books. I mostly used free online courses like Khan Academy to learn what I did.(I would def. recommend them though)

Youtube Channels :

The Organic Chemistry Tutor : Dude puts everything from reaction mechanisms to retrosynth problems down in the simplest possible terms. Does not beat around the bush with euphemisms or stories, gets right to business. If you have trouble paying attention, or lose your mind when a professor goes off on a tangent, this man is your savior. I have crippling unmedicated ADHD and no STEM background whatesoever and this man still managed to teach me 2 separate ways to execute a Gabriel Synthesis

Nile Red : World's most inefficient and most powerful wizard. I am not entirely convinced he's human. Does shit like turning plastic gloves into drinkable grape soda or making sweeteners out of his own piss and somehow makes it explainable to trash goblins like me who only need the science for warlord pussy.

again, anon, holy shit thank you so much. Like you wouldn't believe the amount of damage you've just undone. i have been beating myself into a pulp and spiraling into anxiety about this fic an trying to do everything right and you've given me enough moxie to fuel me for at least the next 10 chapters. If you have any more questions or more specific questions, please do not hesitate to ask! I can't guarantee I can answer them, but damnit I'll try. Take care and happy learning you funky lil moonbean.

#Breaking Bread #megatron #megatron/reader #I know I don't need those tags but lord I'm relishing the thought of ppl stumbling upon this w 0 context #u know what I'ma go ahead and pin this thing.#Took me YEARS just to find out exactly WHAT I needed to learn and WHERE to learn it #if I can save someone from wasting all that time then that'll be nice
