Senku has a sweet spot for you. Not that you noticed, assuming in an innocent way that he did this for everyone. He sure as hell didn't spend his Sunday slaving over perfume oils and perfumery lessons just for the next guy.
"Why did I ever agree to you?" He moans at himself as he checks the temperature on the reflux equipment. Refluxing takes time.
And as patient as he is, after something that takes four to six hours fails twice, it starts getting ridiculous.
Turns out, even with the right equipment, science sometimes just doesn't like to follow the laws of the world. There is no way on earth his setup could ever be wrong. So, leads the question, why was he getting such an acidic pH?
For the past few hours, he had been attempting (unsuccessfully) to obtain ethyl vanillin as a base for his perfume replica. One that you cried for weeks on end about being discontinued before you had the money to buy more. One that seemed to follow you in every single room you went into. One that Senku actually liked on you.
"It would just be better if you exploded right now," he muttered to the reflux condenser, a slight desire to turn the flame to the max and cover the top of the condenser so this could be done and over with and considered an utter failure.
As the mixture bubbled and evaporated into itself, he stared into the abyssal liquid for an answer at his woes. If only he had a magical fairy that would make this for him. Even if all it did was measure all the powders and liquids. He looked on eBay briefly to see if he could find it, but the only listings were half used to far too expensive.
And suddenly: Bingo! Why was he the only one that suffered right now?
Picking up his phone, he quickly dialled a number as he kept an eye on the round bottom flask, making sure it didn't suddenly turn rainbow.
"Helloo?" You responded.
"Yo. Come mine. Now." He hung up promptly. At least as promptly as he could with nitrile gloves, so there was a pause on the phone as he tried to get the screen to register. You heard his finger bash against the phone screen before the call ended.
At least there would be someone to act as his guinea pig to mix the irrelevant stuff as he did mass calculations.
You lived in a student house around thirty minutes from him. So, being you, you arrived an hour after. He'd called you when you were in pyjamas, with drool still on your cheek from when you woke up. You begin to knock on the door, but before your fist even hits wood you're dragged in by your wrist. Suddenly, you donned a white lab coat, safety goggles and blue gloves. Strangely enough, he seemed to have a coat that fit you even though you two were completely different sizes.
You look onto the scene in the kitchen. An array of glassware litters the counters, placed on top of the microwave, table, and the clean ones on the dish rack. There was some stuff bubbling, but you didn't know what it was.
"Hey, don't you share this place with Gen and Chrome? Are they okay with you turning their kitchen into a science lab?"
"I treated them to take-out already, they'll be fine. Anyway, you came at the perfect time. Mixture's done refluxing and cool, so pour it into that beaker for me."
You give the leek-haired man a blank stare.
"Dude, I haven't done chemistry in, like, forever."
"Neither have I. We both do mechanical engineering, remember? Just grab the clamp and pour it."
"Fuck. My beautiful face is gonna get scorched or something. I feel it."
Trying to follow his instructions, you grab a clamp from the far side of the room and take the warm round flask pouring its reddish-brown contents into a beaker.
"Hey, is this my perfume?"
"Bingo."
"Looks like. Uh. Shit."
"It's not even half way done, stop complaining."
Senku grabs a pipette and takes some of the mixture, haphazardly testing it over the kitchen counter against pH paper. Then again, you didn't know any better.
The paper turned a purplish-blue colour.
"Is that good?"
"Thank God. Finally, you're my good luck charm."
You give out a small 'yay' before you find that your limbs are way heavier than when you came in. Your eyelids feel like 10-ton stones taped onto your eyes.
"Senku, I'm so tired," you wail out, trying to shake your body awake. The genius glances at you and clicks his tongue, as if in revelation, grabbing a mask that had been thrown onto the counter and slapping it on you.
"Sorry, I used chloroform as a formylating agent. Thought it left by now."
"What...?"
"Chill, I'm like immune by now," he nonchalantly states, finger rubbing the outside of his ear, "Plus, the windows are open."
"Ugh, I knew I shouldn't have come here. Maybe you're a serial killer and this is how you finally murder me."
"If I wanted you dead, you'd be dead by the time you stepped in. Actually, before you even stepped in. I'd put some nerve agent on the door waiting for you."
"You're so mean!"
"Shut up. Grab the acid and pipette it slowly into the mixture."
"Why am I doing this now?"
Your complaints fell on deaf ears, as Senku leaned against the counter, you began pipetting small amounts of dilute hydrochloric acid into the mixture. Although you couldn't see his gaze, the thought of him watching you so closely started embarrassing you.
"Am-- am I doing this right?"
"Yes, you're doing good, keep going."
The sliver of praise shot your heart like cupid's arrow, thankful the mask hid the stupid smile on your face. The addition was painstakingly slow, as after you added the acid you had to stir (for at least ten seconds, Senku kept telling you off for trying to shorten it).
"Okay, all in."
"Amazing work." You perk up again, "now move it, idiot, I'll do the extraction and drying, or else I'm sure you'd fuck it up."
"Okay, fuckin' Bill Nye over here." You drop the pipette and let him star in his own show.
He grabs a glass rod to stir the liquid as its your turn to lean against the counter, happy that Senku had actually began making your perfume. It was meant to be a replica of a mid-range perfume, with a vanilla base note and lemony undertone. Your heart is still shattered when you found out it was discontinued.
Senku continues doing his magic, grabbing what looks like the flask-equivalent of a massive tear drop and separating some liquid from the other. He adds, he funnels out, he adds again. A bit of shaking.
Although this wasn't the main way he wanted to spend his weekend, he liked doing acts of service for you. He never admitted it, but hearing your words of gratitude really boosted his mood. Not a completely illogical release of dopamine, but one he'd rather keep a secret.
"This is an Erlenmeyer flask," he shows you a piece of equipment that holds no relevance to your life at all. But you listen to his talk anyway:
"I'm now going to dry this organic layer by adding 8g of sodium sulfate, if my calculations are correct, at least. A little excess doesn't matter much."
Considering he hadn't picked up a pen for the past fifteen minutes, he must've done them mentally using estimations.
"Then, I'll filter it again and use my rotary evaporator to get the ethyl vanillin." He continued explaining, his mind working ten steps ahead of his mouth as he began formulating ways to get the lemony scent involved.
"Your what evaporator?"
"Just a small piece of equipment I brought from home. Like... a thousand or so pounds?"
"Huh."
"It's small, only 2 litres. Thankfully, this is way less than that."
You knew Senku's habit to spend all of his money on science equipment, considering that the university didn't allow (and for good reason) any random to use it. Even though Senku was barely a random, he was not part of the chemistry school.
"Man, is this why your diet consists of instant noodles and shitty energy drinks?"
"All in the name of science."
"More like in the name of vitamin deficiency."
He shakes his head, disagreeing with your objective fact.
He picks up the beaker, swishing the contents around to inspect them.
"Anyway, you're done, you can leave now."
Your mouth opens in surprise, eyebrows furrowing.
"You seriously got me here just for twenty or so minutes of work?"
You stare at him as he shrugs, putting his finger in his ear.
"I wasn't sure whether it would oxidise properly, and the rest is too complex I'd rather you not mess about with it."
You scoff, taking off the gas mask.
"Don't give me attitude, I'm spending my weekend doing something for you." He continues.
With that logic, you couldn't be that irritated.
"Any take away left?" You try your luck. He shuts it down quickly, telling you to get out.
"Well, I guess I'll be going now."
"Mm," he hums in response.
"Well, I guess I'll be GOING now," you repeat louder. He glances up at you.
"See you. Is that what you wanted me to say?"
"Maybe. See ya'!"
You shake the lab coat off, trashing the gloves as you leave the kitchen. Senku watches you leave, then he lets out a sigh he didn't even know he was holding in. His shoulders are tense-- far too tense for such a small interaction.
He places the beaker on the table, screwing his eyes shut. What a completely illogical emotional response to your presence. He was testing whether he felt anxious around you, having eliminated a various collection of factors. He really did have a crush on you. It was a hypothesis, one that he knew was probably right, but there was some shame in that realisation.
He was meant to be your friend, an intelligent shoulder to rely on. Not a lovestruck boy with a playground crush. He didn't feel shame particularly due to the crush, but due to having such an emotional response to just one person.
Senku was emotionally intelligent enough, a surprise to everybody who just hears about him but never meets him, but for some reason he had never computed the possibility for love. Maybe, just maybe, if he immersed himself in his work enough he could forget. That was tested and failed.
So, instead, he decided to play into it. A crush is just an absence of information, holding someone to idealistic standards that they never could achieve. You're human, he's human. He thought he could find a logical pathway out of this before his hands start shaking and tongue ties when he looks at you. But he didn't. Now he's stuck like this, as your bus boy.
𓆩♡𓆪
You didn't see Senku during morning lectures, which wasn't unusual for him when he knew the content already. Hell, half the time you overslept them anyway. You sat at the back row with Chrome, listening to the lecturer drone on about thermodynamics. Chrome's hard at work making notes on the mathematical equations, whilst you try to balance your pen on your upper lip. You were still listening... kind of.
Your mind kept going back to last week, when Senku agreed to make the perfume for you.
Senku had a look in his eye. You weren't sure what it was. Affection? Amusement?
You and Chrome spent the next free period together, staying at one of the university cafés.
Nursing your matcha, you read over Chrome's notes on his laptop.
"This is so not how to derive this... how did you even? Wait," you scroll along his calculations, "that's what I got. How did you even land here?"
He shrugs, "Sai taught me some tricks."
"Yeah, but you did them wrong. Look here, you completely forgot the power."
He snatches the laptop back, a frown etched in his expression.
"X to the power of four... doesn't differentiate to three-x to the power of four..." He reads it aloud, laying his chin in his hand in thought.
You concur, "Yeah, it doesn't."
"There you are."
You turn at the voice, seeing Senku. He was wearing a black NASA sweatshirt, with grey sweatpants. His backpack is slung over one shoulder, one of the zippers open and his books half-hanging out. He's holding a test tube up containing a pale-yellowish liquid.
"Your perfume is done, idiot."
Your face instantly lights up. Leaping up to grab it, Senku raises it higher than you can reach. He looks up and away from you, a smirk playing on his face.
"Aren't you forgetting to say something?" He asks with mischief lining his words as you try to jump to grab it. You latch onto his arm, and being as weak as he is, his arm practically collapses from your full body weight. Now he's hunched forward over himself, you take a step back perfume in hand.
"Thank you!" You hold the test tube as if it was your baby, cradling it in your arms.
"I can see Kohaku's influence from a mile away..." He stretches his arm, rolling his shoulder.
"You made her something, Senku?" Chrome questions the leek-head, who shrugs in response.
"You told me it was for a science competition," he continues, crossing his arms. That earned a snicker from you.
"Woah, are you that insecure you had to make a lie up about it?"
"No, I just didn't want Chrome annoying me about..."
He trails off, realising he was saying far too much. Chrome and Gen both knew Senku's almost debilitating crush on you, and they often teased him for it. So, he finds the next logical reason. A white lie.
"...About making him help so much just for this."
"You helped?"
"Yeah, only for a bit. I made sure the hot plate didn't change temp' all of a'sudden while Senku did his labs."
"Aw, thank you both! Now," you pause to build suspense, popping the cork top off, "time for the -- oh my god."
The smell practically permeated the room. It smelt amazing, exactly like the one you used to wear, just a million times stronger. It instantly glued itself to every fibre on your clothes and you hadn't put it on yet. You didn't even dare take an actual whiff of the liquid, your lungs would collapse under the vanilla.
"Woah," Chrome didn't know whether to cover his nose or not. It wasn't bad, it just was too much.
"That's... super strong."
"Yeah, I forgot to say, it's a perfume oil so it's way stronger than what you were buying. I would've diluted it for you, but I only finished it today and I can't miss afternoon lectures."
"You could've given it to me tomorrow."
"I'm not working on that abomination anymore. I almost lost my sanity," Senku shakes his head vigorously. At least he knows he never wants to go down a career path in perfumery, or more broadly organic chemistry.
The smell was still omnipresent even with the cork off now. It was like a Pandora's box, now it would never be fully closed. Senku must've used a hydraulic press to cork it shut considering you didn't smell anything until now. Some people around covered their noses with their shirts as they continued typing, embarrassment creeping up your neck.
"I don't even need to put it on, just carry it around with me and the next room'll smell me."
"If you don't like it, I can take it ba--"
"No. I want it. Thank you."
Chrome's expression is impish, eyes bouncing between the two of you.
"Gen will love this."
You both look at him, perplexed. Senku seems to catch up quickly, colour flying from his face.
"Don't speak a word of this to Gen, you--"
Chrome slides his laptop off the coffee table and into his bag in one smooth motion, and shows Senku Gen's contact number.
"You idiot--!"
Chrome jogs out of the cafe with an evil smile, leaving you frankly confused. You would ask Senku, but he's so red you're worried his blood vessels will all explode.
He cups his face in his hand, a sorry bid to hide it from you:
"I'm going to class..."
"Class doesn't start for another fifteen minutes--"
"I'm going to class," he repeats, turning and walking off. You knew he liked to sulk in Dr. Xeno's office from time to time, so you'd probably find him there. Helping out a friend isn't such an embarrassment, you'd think. You tilt your head, finding yourself alone now. Maybe Senku resented you in some way? Your heart drops slightly at the thought. No, you were overthinking it. It was probably just Gen teasing Senku about making cosmetics rather than spend his time drooling over schematics.
Sitting back down, you look at the test tube in your hand. You can't help the stupid smile on your face, even though it's absolutely killing your nostrils. You'd have to look up how to dilute perfume when you get home. Or maybe right now, considering you still had three hours of lectures and didn't want the lecture theatre to smell like you for the next... forever. You'd have to hide the test tube in a bush somewhere outside the engineering building. Yeah, that sounded good.
"Mm, it smells like cupcakes. Is there a new bakery or something near here?" Chrome asks Senku as the three of you leave the building.
You crouch down at a nearby bush, avoiding the cans thrown by students, and collect your weapon of destruction.
"Oh."
Chrome was left disappointed and hungry for pastries the rest of the day.

"Senku?!"
Your exclamation was a tad bit too loud, earning curious glances from the people around you. But in your defence, this was the first time you had seen Senku at pres. Nonetheless, dressed for the club.
He clicks his tongue at you, looking away in embarassment. Gen, who must've been the one to drag him out, waves at you to come over.
"I can't believe this. I must be hallucinating," you say, half-tipsy from the shots you'd taken with Yuzuriha. Reaching out to touch his cheek-- obviously, to check if he was real-- his wine eyes drink you in. Your fingers graze his soft skin, you didn't notice but he leant into your brief touch.
"You and Senku-chan are matching!"
Gen giggles to himself when you both look down at what each other is wearing.
You're sporting a tight black half-sleeve, low cut enough to show your lacy bra, alongside black shorts that ride up enough to almost show too much. Senku's wearing a black tee with long white sleeves, and black boot cut jeans.
You didn't even know he owned clothing that weren't hoodies. 'Inefficient', he'd say about fashion.
"We're matching! Twins!"
"I need to get changed."
"Oh, shut up, you leek head. Is it that bad to match with your b-f-f? Gen! Let's do shots!"
Gen shrugs, as if to say why not, following behind you. Senku considered the possibility for a split second, before deciding to stay sober was the only anchor he still had to a comfort zone. After all, he hated going to the club. He was fine with house parties, since he knew everyone, but clubs were a step too far.
You and Gen cheers to an apple vodka found on the table, you using the cap of the bottle as a shot glass and Gen using a red cup filled with coke instead.
"How'd you even get him to come out?" You hiss at the bite of the alcohol on your tongue, Gen unchanging in his expression.
"A little convincing. You know me, Senku-chan does anything I tell him to."
"That's cuz you blackmail him, Gen."
彡٥ﾞ‶٥彡
"I'll tell her you like her."
Senku, holding a beaker of an unknown clear substance, whirls it a bit too hard at the comment: a splash of the mixture landing on his glove.
"You wouldn't."
"Senku-chan, your glove is melting."
Senku's glare didn't leave Gen, giving him a death stare as he swiftly takes the glove off in one motion.
They were in the kitchen of their shared house with Chrome, Senku coming to the end of a small experiment and Gen eating his dinner right next to the array of chemicals that the genius had been using.
"I told you, Gen, I hate clubs. Why are you forcing this onto me?"
"It'll be fun. You've been doing science-y stuff for the past week, you need a break."
"My break from my degree is the science-y stuff. "
"You know I hate liars, Senku-chan."
Senku gives him an incredulous look, he can't believe the words that had just come out of Gen's mouth.
"Plus, I already picked out your outfit! You'll steal her heart tonight, for sure."
"Tonight?!"
"Better have a shower, Senku-chan!" Gen stands up, leaving his plate in the sink and exiting with a giggle.
彡٥ﾞ‶٥彡
"Just a bit of convincing," Gen reaffirmed, smiling at himself. You hum, feeling the warmth of the alcohol finally affect you.
"Like, did he pay for a ticket already?"
Gen smiles, showing a receipt of two tickets of his phone for the student nightclub.
"You really thought this all out. So... so conniving."
"Senku! My friend, you came!"
Now, it was your turn to look. Ryuusui had just walked in holding a six pack, looking just as astonished as you did at his presence. Senku sighs, before he's attacked by Ryuusui's arm over his shoulder. There's no way he's getting out of this without at least a beer in his hand. How was Ryuusui late, to his own pres?
He's accompanied by Francois behind him, who has a phone in their hand typing.
Gen looks at the clock on his phone screen, rolling his eyes.
"There's only thirty minutes before they stop accepting people."
"Wait, when's last entry?!" You exclaim, holding Gen's shoulder.
"12AM."
"Aghh! Ryuusui, order the Ubers already!" You let go of Gen, now grabbing Ryuusui and shaking him. The smile never leaves his face as he unashamedly checks you out. He drops the six pack on the counter next to him.
He lets go of Senku, and uses his free hand to push you towards his chest, the arm snaking around to envelop you. His lips are so close to yours. Gazing at you in his embrace:
"You truly are a woman after my own heart, is this an outfit for me tonight?" He uses a finger to raise your chin to meet his eyes. You feel a light blush crawl up your neck, he does this to any girl he sees! What a playboy.
Senku rips you out of the blonde's embrace, putting a lazy arm around your shoulders, "What're you saying tonight?" He aims the question at Ryuusui, ignoring your surprised look at him.
"Hasn't she told you? We're going to share a warm embrace after the club in my own room!" Now he was just lying to get under Senku's skin. To anyone else, it seemed as if Senku brushed off the comment, but you knew his tic to rub his ear when he was irritated.
"I didn't hear anything about that."
Francois taps Ryuusui's shoulder, a bid to change the subject, "I've ordered the Ubers. Using your account, obviously."
"Ah, thanks Francois! You're a life saver!"
They hum in response, grabbing two bottles from the six pack on the counter. They open them both, handing one to you.
"Thanks, Frenchie!"
You take a swig, and Senku snatches the bottle from your hand, drinking himself. It's not like he was always sober, but this was the first time he had willingly taken a drink by his own accord. You blink, astonished at this 180 Senku did tonight. First, showing up to go to the club, now drinking?
He doesn't heed your shock, staring daggers at Ryuusui who's now chatting away. You didn't like the blonde, right? You knew he was just flirty and his advances didn't mean anything? Senku focuses again when he feels his arm being taken off your shoulder.
"Oh, sorry."
"Don't worry, Senku. Why'd you come out anyway? This is so not you."
"Change of pace."
Senku stops answering you on the topic, which leaves you wondering what exactly Gen hung over his head to get him here. Maybe Gen had kidnapped his dad and was holding his hostage. Payment: night out to the student club. Maybe this was the most expensive ransom Senku had to pay him.
People begin trickling out, getting into the Ubers Ryuusui had singlehandedly paid for. And he never expected payment back, if anything, that was an offense to his generosity as a host. Who said a playboy can't also be a philanthropist?
You sat in the middle of the car, to your left Senku and to your right Yuzuriha. At the front, Taiju talked the driver's ear off. Senku still had the bottle in his hand, half-full now from small sips.
"You need help finishing that?" You ask, and he hands it over to you. You drink a quarter, and he drinks the rest. His cheeks were viciously red for the small amount he drank, but he seemed to retain constitution. Well, apart from:
"Alcohol increases the effects of gamma-aminobutyric acid. This causes sluggish movement, slurred speech, and slow reaction time. Alcohol also decreases the effects of glutamate, which regulates dopamine in your ventral tegmental area..."
He was muttering to himself the effects of alcohol on the brain. What a nerd.
Senku stared out of the car window, watching the lamp posts strobe as they drove past. Once in a while, he'd watch you from the reflection, uncaring for the conversation you were having with the couple at his side. You were so beautiful.
The car stopped where the other Ubers had accumulated. The group began to exit:
"Senku, be careful in the club, someone small like you is gonna get lost easily!" Taiju laughed, Senku rolling his eyes.
"Whatever, meathead." He wasn't even short, well, not compared to the gorilla Taiju.
.
.
.
Senku had absolutely zero idea where anyone was. He had imprisoned himself on the sofa at the far side of the dance floor, where he was stuck between the armrest and a drunk group of students. This was a living hell, why had he agreed to come?
Opening up his phone, he begins to click on his Uber app to get an estimate on how expensive it would be to leave right now.
His eyes widened, "Fuckin' fifty pound?!"
His house was only maybe a fifteen minute car ride. He'd have to walk, or find Ryuusui, suck up his pride and beg him. Resigned, he pocketed his phone before a hand landed on his shoulder.
It was you.
You were shiny, forehead heavy with sweat, but your makeup still looked glowing. You gripped onto him like he was your last anchor to reality itself.
"Hey, where's everyone else?"
You ignore his question, out of breath.
"You alright?"
" 'M so tired, Sen..."
"Sen?"
"There's no seats, Sen," you moaned. He rolled his eyes, tensing his legs to get up for you. Gripping the sofa, he only barely raised himself.
"Okay, princess, just--"
Suddenly, there was a weight on his lap and his chest.
Senku gasped lowly when you placed yourself onto his lap. Your ass pressed right into his-- he needed to focus. Do not think about it. He repeated those words like a mantra in his mind as one hand gripped your waist so you wouldn't slide off.
"Let me just stand up, so you sit down properly--"
"Noo," you slurred, pressing your back into his chest, "I like it like this, Sen."
Fuck, did you know what you were doing? With the glazed look in your eye, probably not. The nickname made his dick twitch in his boxers. Probably unbeknownst to you, your ass kept moving against his jeans. With your full weight onto him now, the pressure just felt... great. Your ass shifted into a better position, and he just couldn't help to be half hard now.
Senku rested his head against the club sofa, trying to push against the fabric to get as much space between your body and his. But it wasn't working. You gripped his thighs, only for balance, but the way your nails dug into him made him red.
"Don't think about it," he muttered to himself.
"Hm, what'd you say, Sen?"
He sighed. He moved his hand lower down your waist, so you wouldn't slide off. That's all it was. You were sitting down for a break. Because you were dancing. You rested your head between his collarbone and his shoulder.
Tentatively, he looked down at your chest. This was the best view he could've dreamed of. Objectively. Mathematically. If he looked closer, he could see through the fabric of the bra and your perked nipples--
"Sen, come and dance with me..."
"Not now," he said almost reflexively, gripping your hip tighter. Senku didn't want this to end. Also, if he stood up, everyone would see his hard fucking cock through his jeans. Trying his luck, he moved his other hand from the sofa onto your other hip, pushing you further back into him.
"You're slipping."
"Hm? Sorry..." you adjusted yourself against his dick, earning a low moan from Senku. Again, you relaxed yourself onto him. He found himself stopping his own hips from raising to hump your ass, pressing down on your hips so he'd feel more of you. You didn't notice the details, just feeling Senku holding you.
He now rested his face between your neck and shoulder, lips grazing the back of you. He could smell the perfume he made for you onto your skin. It sent a shiver straight to his cock. Senku was sure now he had a damp patch just from precum on his boxers.
Sneakily, he continued to press you into him, his lips caressing your collarbone. You did notice his lips, goosebumps forming. You leant into him, humming happily at his touch. You waited for this for... forever. Was this a dream?
"Sen, what're you doin'?"
"Nothing," he says calmly as he begins to kiss the nape of your neck, you won't remember this, he tells himself. He can't help it, you look too beautiful like this. His hands inch closer towards the button on your shorts, stopping short at your stomach.
He breathes into your ear, tickling you. You chuckled, tightening your grip on his thighs. Although, good things can't last forever.
To his horror, he saw a certain blonde notice him and you. To his further horror, he was approaching.
"That's where you two were!" He shouts over the loud music. You wave with both hands, a light smile on your face.
"Haha! You're plastered!" He tells you, earning a pout, "At least you're taking care of her," Ryuusui told Senku. It seems like the blonde didn't notice Senku's dusty pink cheeks. Or if he did, chalked it up to the beer he had an hour ago.
Senku's head hit the backboard of the sofa, facing up to look at Ryuusui.
"Where's everyone else?"
"Hm, good question," Ryuusui says, "Francois is getting drinks at the bar, I think Yuzuriha and Taiju snuck off somewhere... Kohaku and Gen are dancing. And I'm here!"
"Tell Senku to dance!" You didn't use the nickname infront of Ryuusui, Senku noticed, were you embarrassed? The leek-head found it endearing. He'll bring it up tomorrow, when you're inevitably crashing at his place because it's closer.
You stood up suddenly, and Senku rushed to put his hands in his pockets. He was almost caught, but neither of you noticed. You grab Ryuusui's shoulder and shake him, pointing at Senku as if you were a child tellling their mum something.
"Tell him to dance!"
"Senku, come and enjoy yourself!"
"I'm good here," he says, looking away from you. You're now drunkenly grabbing the inside of his elbow, both trying to get him to stand up and take his hands out of his pockets. His life now stakes on the fact that he absolutely ten billion percent cannot take his hands out of his pockets. Lest the tent that's formed is found. Over his dead body.
Thankfully, you're even weaker than the genius, so you can't pry him from his safe haven of the sofa. The blonde shakes his head, telling you to just leave him.
"He'll come up when we see how much fun we're having," he teases, gripping your waist and pulling you towards him.
Sure, Ryuusui. But did she sit in your lap? Senku is going to live off this memory for a couple of weeks.

You open the door to your student house, seeing a familiar figure walking down the street. The gravity defying, spring onion-adjacent hair could only be one person.
"Senku! You're early!"
He glances up at you, slightly surprised you had seen him come before he had even rung the doorbell, "Well, it's rude to be late, isn't it?"
"You always come fifteen minutes early, you're too responsible."
"Whatever, move it, idiot."
You move out of the doorway to let him inside, stepping back into the hallway to give him space to remove his shoes. The rest of your house mates had left for class, leaving you and Senku who had a free day alone. This would be the day you finally locked in! You were determined. That's the whole reason you invited this genius leek head over in the first place.
"I've set up the most efficient study spot up in my room. Fluorescent lights to avoid any napping, and whatever hertz frequency for full focus."
"Those frequency playlists are just placebo, you know that, right?" He responds. You scoff and lead him up the stairs to your room, swinging open the door to your creation.
The curtains were open (normal), lights were on (slightly less normal in the middle of the day), desk lamp was also switched on...
"Hey, isn't this a little excessive?" Senku asks, a little exasperated as he beelines to save your electricity bill.
"Dude, no, or else I'd fall asleep so fast. Leave it alone!" You shoo his insistent hand away from the desk lamp, illuminating the notes you made before he came.
"Anyway, I'm gonna focus on thermofluids-- fluid dynamics, the derivation for the centre of pressure and rest of the module."
"Sounds good, but I've already learnt it."
"That's exactly why you're gonna tutor me!"
His hand brushes his hair back, backpack beginning to slide off his shoulder and onto the floor, "I was under the impression this was an individual study session."
"Yeah, but you're just going to help me a tiny bit. Trust me, just one or two questions."
As he opened his mouth to protest this arrangement, your phone went off. Putting up your hand to shush him, you pick it up.
Senku continues to look around the room, apart from the weird screeching sound (which he assumed was the studying frequency video you had put on) and near hospital-quality lighting, it was a fitting room for you. Posters covered the walls, an army of plushies littered the side of your bed. It was... cute. In a way.
As you chattered on the phone, which he was only half listening to your conversation, he took an opportunity to discreetly check you out.
You had a off-shoulder shirt, so baggy it doubled as a dress. It seemed you hadn't bothered changing out of your pyjamas to meet him. A lewd thought crossed his mind if you were even wearing shorts underneath. He quickly dismissed that, crush or not, he was here for business.
"Ah, okay. I'll be there, just wait."
You hung up, and his red eyes find the nearest object that's not you. A textbook, opened and highlighted to the brim.
"Sorry, Senku, one of my friends just got in a small accident a couple of streets over."
You pulled a pair of sweatpants from a chair that held your pile of semi-used clothing, and began to hop to put it on. To Senku's slight dismay, you did have shorts on.
His face was unchanged, but you added quickly: "Seriously, just a bump! But Luna's super worried so I'll go over. It'll literally take less than an hour."
You could feel him groaning into himself, backpack hitting the floor with a loud 'thud'.
"Oh, shut up, you'd do the same if it was me!"
"I'm ten billion percent it'll take longer than an hour. It takes me an hour just to get here."
"Yeah, then just stay in my room for a bit. Okay, I'll be back!"
And the door to your bedroom shut. Now he was all alone. He rolls his eyes at you, although understanding at helping another. With a plop he places himself onto the edge of your bed, scanning the room.
He could study by himself, but to be honest, he knew 99% of the content and was mainly here to help you (although unadmitting to that fact). As he ties his ombre hair, he spots your laundry basket at the far side of the room with something pink poking out of it.
Looking a little closer, it was pink, and it's lace had a cute heart pattern that totally suited you. There was a mental pause, realising that it was your underwear.
He couldn't.
He shouldn't.
But what else could he do?
Senku found himself standing over the basket, ignoring whatever feelings he felt souther than his abdomen, staring at the culprit. It really would suit your ass. That thought didn't go away as easily as the one before.
He could imagine rubbing against your ass whilst you were wearing this cute pink set, using his dick to push your panties to the side and--
"Fuck, what am I doing?"
He locks the door to your own bedroom, and grabs the pair of underwear from the basket. In a state of half horniness and half efficiency, he grabs a shirt that he spots at the top aswell.
A scanty top that you used to go out, one he knew was smothered in perfume from the amount of times you'd come up to him on the rare occasion he was at the club.
Shaking your tits in his face as all he could smell was the perfume he made you for your birthday because you begged him.
Laying himself on your bed, he quickly brings the top to his nose, filling his lungs with you. It intoxicated him. He knew, at the end of the day, this was just your axillary sweat and hormones that had accumulated were messing with his own. But the effect was still prevalent. He exhaled, in a rush, trying to pull his jeans down just enough to pull his cock out.
He palms it through his boxers, a small wet spot accumulating from his precum. Only you could reduce him to this. A genius into a feral sex fiend. Although knowing the house is empty, he still muffles his moans by biting down on your top. Senku knows he's short on time, but with the state he's in right now he should be finished long before you're back.
Finally, he releases his throbbing dick from his boxers, precum dripping down a green vein. In his other hand are your cute pink panties, ready to be defiled by your supposed friend. His cock twitches at that thought. Maybe, a more rational part of him thought, it was the idea of a taboo between friends, something to do with the psychology of himself. He had read a paper about that from the University of Texas, in an attempt to understand his complicated feelings about you. Gen was doing Psychology anyway, not him. Maybe he should ask him.
Pushing all rationality out of mind, he rubbed the cotton part of the underwear against his pink tip-- spreading his dribbling precum around the throbbing top. Realising he was still biting down on your top, muffling his whines, he lets go with a string of saliva. As he continues to slowly rub your panties against his shaft, he takes another smell of you.
"Fuck, what... ahh, am I doing? Fuck... I'm sorry--" he says half heartedly as he starts to stroke the full length of his cock, red from teasing the tip too much.
Senku considers spitting to make it smoother, although above him to usually do it, he can't help but imagine your warm hole wrapping around him, the tight underwear brushing against his dick.
Some strands of hair had already escaped the man-made prison of the hair tie, and stuck to his damp forehead. He squeezes-- hard-- at the base of his cock, prompting a loud groan as he stretches your panties; still careful not to rip them. His tip weeped, making dark spots on your underwear.
He continued with the long, languid strokes, gripping his dick tighter as your pussy would when he began to fuck you. He knew you would mould around him, like a good friend would. Your shirt was a permanent placement on his face, so every breath he took in pleasure would entail your scent.
You would bounce that ass of yours on his dick, crying out when he penetrated you harsh but slow. He was trying to find the best spot to make you moan, just like a good scientist would. Repetition, then elimination. Like a vector field he was calculating. Senku moaned again, red eyes staring at your ceiling, all shame that once filled them gone and replaced with unadulterated bliss.
Speeding up his strokes, your underwear strained at the stretch he was forcing it under. For a second, he heard a rip in the lace and thought he had lost it all. But it must have been a stitch of the heart snapping, because the overall integrity was alright. So, he continued. Up, down, squeeze the base of his dick. He was close.
"Hah... hah... fuck."
Unbeknownst to him, a reasonable amount of time had passed already, and the front door locked.
"Hey, Senku? I'm back."
You called out, to no response. He must have headphones on. You began to creep up the stairs. Senku never had good instincts.
He removed your shirt from his face, knowing that the white cum would show on this black little top. With one last swipe of his red tip, he focused on the upper part of his dick, jacking himself off with no other care in the world.
"Hah... hah..."
Precum dripped down his shaft, highlighting his pale cock and veins. He was in his own world.
You tried the handle to the door, but found it was locked.
"Huh? Senku, why'd you close the door?"
"Hah... gnhh.."
This sounded like... painful groaning? Was he alright? Did he do another one of his stupid experiments somehow and gotten hurt? You began to panic, searching your pockets for your bedroom key.
"Senku, one second," you pulled it out, and in less than a second got the door open.
"Fuck!"
He came, hard. His cum shot into your panties, and through gaps in his shoddy defence splattered his shirt in proof of his crime. It seemed he hadn't heard you, as in sudden exhaustion he turned his cheek from the door.
You looked on.
Surprised.
Appalled?
You didn't think you were appalled, maybe even if you were meant to be. Something in you was slightly happy, although felt exposed.
The green haired man continued jacking himself off from completion, legs shaking at the overstimulation he had given himself. With the last of the hot cum out, he sighed.
He seemed to regain some energy, sitting up using his forearms.
"I need to get this cleaned before..."
Although it was meant to be a cursory glance to the door, his vermillion eyes stared at you. At what was meant to be a locked door. You were there. You were-- you saw-- you--
"Shit, it-- it isn't what it looks like, I swear," although genius by academic accounts, the words that had just fallen out of his (lying) mouth were objectively dumb.
Still speechless, you closed your mouth that didn't know was wide open.
"You know, if you wanted my panties, you could have just asked."
