sleepyhead pt. 1

includes: senku, gen, chrome, ryusui

falling asleep on them (っ˕ -｡)ᶻ 𝗓 𐰁

tags pre-relationship, fluff!!

warnings none

a/n: I have more characters written for this but I’m splitting it up so that it isn’t giant (I’m also lazy…)

senku

senku pretends to be unfazed when you nod off near him, but his mind immediately calculates how to keep you comfortable without waking you up.

he’s used to working alone for hours, so the sound of someone breathing softly beside him feels unfamiliar. but it’s not unpleasant—it makes the space feel alive somehow.

when your head slips onto his shoulder, he stiffens like a startled cat before forcing himself to relax.

later, he’ll make fun of you for “crashing like a dying battery,” but secretly think about it for days.

it was late in the lab, the faint hum of glassware filling the silence. senku had been talking for what felt like hours, explaining chemical reactions with his usual sharp enthusiasm. you tried to keep up—really—but his voice was oddly soothing when he wasn’t lecturing, and your eyes grew heavier by the minute. the next thing you knew, your head slipped against his shoulder.

senku froze mid-sentence, the word “reaction” dying in his throat. “oh, great,” he sighed under his breath, but he didn’t move. the warmth of your cheek against him made his pulse spike in a way he wasn’t ready to acknowledge. he glanced down, watching your lashes flutter as you breathed softly, utterly unaware of the chaos you’d just caused.

after a while, he adjusted the blanket draped over his legs and let it fall over yours too. “what a pain,” he whispered, but the corners of his mouth twitched into a faint smile. maybe the science could wait—just this once.

gen

when you fall asleep on him, gen’s first reaction is amusement. a sly grin creeps onto his face as he tilts his head, “wow, I must be really boring tonight.” but he doesn’t move away—not even an inch.

he’ll watch you out of the corner of his eye, analyzing every detail like you’re some psychological puzzle—the steady rhythm of your breathing, the way your hand twitches slightly in your sleep.

he hums absentmindedly or plays with a strand of your hair while you rest.

when you wake up, he immediately pretends it never happened.

you hadn’t meant to fall asleep—one minute, you were listening to gen talk about his “brilliant psychological insights,” and the next, your head was slumped forward, the warmth of the fire lulling you under. when he realized you weren’t responding anymore, he paused, blinking down at you. a soft laugh escaped him, low and quiet.

“eally-ray?” he murmured, leaning back against the log. “out like a light. and here I thought I was fascinating.” his tone was teasing, but his movements were careful as he shifted just enough for your head to rest more comfortably against his shoulder.

the firelight flickered across your face, and gen found himself staring longer than he meant to. he wondered if you dreamed easily, or if your mind stayed just as restless as his when things got quiet. his fingers twitched, almost brushing a loose strand of hair from your cheek, but he stopped himself with a quiet exhale. “don’t go reading into this, alright?” he whispered, though you couldn’t hear him. “I’m just… being nice.”

chrome

when you fall asleep next to him, chrome’s brain short-circuits. he immediately starts overthinking—should he move? wake you up? or just sit perfectly still until the end of time? he ends up choosing the last one.

despite his nerves, he finds himself softening as the minutes pass. he’s not used to being the one people rely on, and it makes his chest ache in the best way.

he tries to act casual when anyone passes by, but the red in his face gives him away instantly.

later, when you’re gone, he’ll sort through the stones you collected and quietly reminisce about the feeling of you beside him.

you and chrome had been sorting through minerals for what felt like hours, the pile between you slowly shrinking as the night dragged on. your voice had gone quiet a while ago, and he assumed you were just tired of talking—until he felt a sudden, warm weight against his arm.

he glanced down and nearly dropped the stone in his hand. your head rested against his shoulder, eyes closed, completely out. “uh..” he started, panic spreading across his face. he didn’t dare move, afraid you’d wake up and see how red he was.

minutes passed, and his nerves settled into something sweeter. he carefully shifted so your head rested more comfortably. “you really trust me, huh?” he mumbled, a tiny smile tugging at his lips. when kohaku called his name from outside, he hissed, “shh!” like it’d disturb you, then he realized how ridiculous that sounded.

ryusui

ryusui doesn’t mind when you fall asleep on him—in fact, he loves it. to him, it’s proof that even your subconscious can’t resist him.

he’s greedy with moments like these. even if you just slump against his shoulder for a minute, he’ll shift to make it last longer; adjusting his position so you don’t wake up too soon.

if anyone teases him about it, he’ll laugh it off with a flamboyant, “what can I say? I’m irresistible, am I wrong?”

after you wake up and apologize, he waves it off as if it’s nothing significant. yet he stays beside you, just in case you decide to drift off again.

the night breeze was gentle, carrying the faint scent of salt and smoke across the deck. the ship rocked in a slow, steady rhythm beneath the stars, and ryusui leaned against the railing, recounting some grand story. you tried to listen, but his voice eventually blurred into the sound of the waves. before long, your head dipped, and you slumped gently against his shoulder.

for a second he froze. then that trademark grin spread across his face. “ha! can’t even stay awake for my genius?” he declared, tone dripping with mock offense. but he didn’t move you away. instead, he adjusted his arm to better support your head, his movements uncharacteristically careful.

he glanced down at you, the moonlight catching the curve of your cheek, and something in his chest tightened. greedy as he was, he decided not to wake you just yet. moments like this were worth keeping. he leaned his head back, closing his eyes briefly as if committing the feeling of your weight against him to memory.

Heyyyy could I pretty please make a request for nsfw Sai Nanami in this Sai Nanami-less time?? Specifically perhapes, just maybe, a reader who has a thing for hands??

Kicking my feet rn reading your stuff btw

𝒢𑄺 — After finding out about how much you love his hands, Sai takes matters into his own !

———

Sai is handsome to say the least, blessed with great features and good hair. But his hands, oh, they’re a different type of handsome— soft and slim, with a few veins that makes them look almost delicate, with these circumstances it was natural for you to develop a love to hold them, but that love was quick to turn into something more intimate, more deeply rooted and fuelled by your burning desire for him.

“fuck— right there..!” you whimper, struggling to hold onto a thread of self control that quickly slips out of reach, its especially hard when Sai is showing no mercy— if you want hands, you’re getting them.

he’s knelt infront of you as you’re perched on the edge of the bed, grasping onto the soft fabric that drapes onto your bed, in an effort to ground yourself from his fingers plunging in and out of you.

his eyes are glued to your pussy, the slick sounds of arousal and his name sliding off of your tongue like music to his ears, the sort of song you could listen on repeat and never get bored. He swallows hard, a deep blush creeping up his neck as he tries to keep his composure. “mm, you like that? right there?”

you nod frantically, hips twitching and thighs shaking as he doubles his efforts, fingers working to rub that perfect spot inside you that gets you arching off the bed. his thrusts are calculated and precise, making mental notes of exactly what makes you tick. “you’re close” he doesn’t necessarily ask, more of a statement as he feels you fluttering around his fingers. “yeah, oh shit, please don’t stop—“

everything becomes a blur, the room, him and yourself as you reach your peak, your mind singularly focused on the sparks of pleasure travelling around your body, causing you cry his name in ecstasy.

as you come down from your high, his fingers still pump in and out of you, drawing out each ounce of pleasure whilst you tilt your head back, searching for a breath. His eyes meet yours, glimmering in the light “was that good? you want more?”

he sure knows how to put those pretty hands to good use.

PINNED- ryusui oneshot!!!

ryusui x reader smut!

nsfw- this has nothing to do with my ryusui fanfic greedy, just a random oneshot

The ship creaked quietly under the night sky, half-finished. You hadn't expected to be cornered against one of its wooden beams, Ryusui's body pressed flush to yours, his mouth devouring every word you might have said.

His kiss was hot, demanding, tongue sliding against yours like he owned you already. He broke away only to grin down at you, eyes burning with a hunger that was more dangerous than the sea itself.

"Do you know what it does to me, my treasure," he purred, one hand tilting your chin up, "to see you shining even in this primitive world? To know you are mine?"

You opened your mouth to retort, but his hand slipped beneath your clothes, and your breath hitched instead. His fingers trailed deliberately slow across your stomach, lower, lower, until they brushed where you needed him most. The smug tilt of his lips deepened when you shivered.

"So wet already?" he teased, voice low. "Ah, but of course—you're exquisite in every way."

Your protest came out as a gasp when he pushed your legs apart, fingers slipping against your folds, stroking lazily, deliberately, until your knees weakened. He pinned your wrist above your head with his other hand, forcing you to lean into him for support. Every movement was calculated, controlled, yet desperate in its own way—greedy.

"Look at you," he whispered against your ear, teeth grazing the lobe, "my divine treasure, trembling under my touch. Say it. Say you're mine."

When you refused, biting back the words, he chuckled darkly and dropped to his knees before you could stop him. His golden eyes glinted up at you as his hands spread your thighs apart, and then his mouth was on you—hot, hungry, unrelenting.

You cried out, the sound muffled quickly by your own hand, but Ryusui yanked it away. "No, no, my love," he said, licking you with a slow drag of his tongue. "Let the world hear how beautiful you sound."

He buried himself between your thighs, lapping at you like a man starved, tongue circling and plunging until your hips bucked against his face. He groaned into you, savoring your taste, drinking every drop of your pleasure. When you came undone, trembling and gasping his name, he licked you through it, greedy for more.

But Ryusui was never satisfied with just one taste. He rose, wiping his mouth with the back of his hand, grinning like he'd found gold. "Perfect," he said, voice husky. "But I'll need more."

He freed himself from his pants, hard and aching, pressing against your slick entrance as he leaned in to kiss you again—deep, messy, letting you taste yourself on his tongue. Then, with one slow, deliberate thrust, he filled you.

The stretch made your breath hitch, and he groaned low in his throat, burying his face against your neck. "Ahh... tight around me already. You were made for me, weren't you, my darling?"

He didn't give you time to adjust before he began moving, hips snapping forward with a rhythm that was both punishing and worshipful. Every thrust drove you higher, his hand gripping your thigh to hold you open for him as he took and took and took.

"Beautiful," he panted, pressing kisses across your throat. "Every sound, every shiver—it all belongs to me. Say it. Say you're mine."

This time, when the words tumbled from your lips, he groaned like he'd claimed the world itself. He fucked you harder, faster, chasing his release while coaxing yours again, greedy as ever. And when you broke apart beneath him a second time, he spilled into you with a shuddering moan, holding you tight as though he'd never let go.

Even afterward, when your body was trembling and spent, Ryusui's hand stroked your cheek, his smile softer but no less intense. "Exquisite," he whispered, kissing you gently now. "The greatest treasure of all is you—and I'll never stop being greedy for you."

Hiihihi

I just wanted to say I really liked the way you wrote Senku!!! :3 and I was wondering if you had any more thoughts on the guy. Headcannons, or quite literally anything. Truthfully, I just wanna hear you yap about him. (Hes an Obsession 💔) Full liberty to write whatever that comes to your mind!!!

(and I completely understand if you don't. Just wanted to let you know how much I liked your thoughts on him :))

Senku Headcanons

Holy shit i'm sorry this took so long. It was not my intention to leave y'all hanging for so long. Especially for an ask when I said my inbox was open. Life's been crazy but that's no excuse. Also really weird question but I ended up making myself a Seto Kaiba (yes from Yu-gi-oh!) multipart fic as a birthday gift to me. lmk if anyone is interested in me publishing it lol. One more thing like two other people tagged me in a song trend and I swear I'll get to it too! I just don't know who to tag next haha. Senku Ishigami x Reader warnings: minor spoilers but they're not really important word count: 2,064 not cross posted on any other platform

Pre-Petrification

Y’all probably started out as classmates who argued about your specific hyperfixation interest lmao.

He noticed you because you challenged him—not emotionally, but intellectually. Most people couldn’t keep up, but you corrected him and were right. (You were NOT playing. It was more than likely something stupid like FNAF.)

He totally pretended he wasn’t interested at first. Played it cool, but Taiju saw the way Senku looked at you when you talked about your interests.

Homeboy wants to learn everything about everything. Hence his sudden bugging about your knowledge on a topic he isn’t fully educated on.

You both stayed after school often—him for his experiments, you for your own interests. Eventually, you started hanging out by accident more often than not.

He offered you coffee from a vending machine one day and casually said, “It’s statistically proven that shared caffeine intake boosts cognitive synergy.” You think that was his weird way of flirting.

The first time you called him out for overworking, he smirked and said, “Tch. Worrying about me already?” You replied, “Obviously.”

He confessed in a weirdly clinical way: “I’ve run the numbers. Being with you would significantly enhance my quality of life. Wanna test that theory together?” (Listen I know this sounds lame but go rewatch the first episode I promise you he talked like this T^T second hand embarrassment rewatch.)

You said yes in the most nonchalant way possible. By jumping up and down.

Taiju had no idea this was coming.

Yuzuriha knew this was coming.

He wasn’t very physically affectionate at first—he’d tap your hand when passing notes or adjust your collar like it was nothing, but it meant everything.

You helped him with a big experiment once, and he added your name to the credits. You argued that Taiju did way more work, so he should get the credit! Taiju just laughed you off.

Senku just wanted your name written next to his permanently. He published the document so you’ll be metaphorically stuck with him forever since nothing truly gets erased once it’s on the internet. Unless of course humanity was going to turn into stone but what's the likelihood of that?

Your first kiss wasn’t planned. You were mid-argument about the stupidest possible thing you could think of, and he just leaned in and kissed you to shut you up. “There. Now can we get back to the part where I’m right?” This just caused the fight to escalate because him, ‘right?’ Who does he think he is? You were totally winning!

He starts explaining things differently to you—not because he thinks you don’t get it, but because he enjoys seeing your reactions.

This is also how y’all became known as that couple who is always on facetime instead of just calling one another. (I get it, I too watch those gacha reaction videos at my grown age.)

When the petrification hit, he was thinking about you. Not in a romantic way like Taiju did with Yuzuriha, but instead in a, “it’s been about 1,245 years so far so they should be at ‘x’ coordinates because they were at ‘y’ when the beam hit.” “Clothing needs to take higher priority than initial calculations. They might not be comfortable being naked in the wild, extreme scenario or not.” Etc.

Stone World

Senku doesn’t realize he likes you right away. He’s hyper focused on survival, but you keep showing up to help—always curious, always sharp.

You challenge his ideas, not to be rude, but to push him further. That’s what gets his attention.

One day you show up with materials he didn’t ask for but desperately needed. He stares at you and says, “…You’re terrifyingly efficient. I like that.”

When you’re injured, he freaks out silently. He’s cold and efficient treating the wound, but he doesn’t sleep that night.

He builds you your own workstation so you can tinker with him. No one else gets one. Chrome whines because yuo don’t even use it half the time!

Gen teases him constantly. “Senku, your little lab assistant’s got you all flustered—should I schedule the wedding, or…?”

He confesses in the least romantic way possible: “I don’t believe in fate, but statistically, I’d rather build civilization with you than without you.” You had no idea it was a confession until he later refers to you as his girlfriend. It’s as much of a shock to you as it is the rest of the villagers.

You tried to kiss his cheek for sharing the cotton candy with Homura. Instead you ended up kissing his lips by accident. Your first kiss tastes like mineral water and burnt sugar from failed wire experiments.

Senku tries to pretend nothing changed after you get together, but he starts letting you touch his stuff. That’s a big deal. The village only has so much material to come by, after all.

You once called him “handsome” absentmindedly. He froze mid-step, dropped his charcoal pencil, and never brought it up again. But he remembers.

You’re the only one allowed to sit on his lap while he sketches blueprints. Sometimes he forgets you’re there until you shuffle. (Note: this does not work when he gets the invention idea at first. He gets too excited and wiggles too much. It’s only for refinement.)

Speaking of notes, congratulations, your new status as being around Senku 24/7 means you’re the official Note Taker of the new world! Title Pending.

“bUt FeVeR, dOn’T tHeY aLrEaDy HaVe A rEpOrTeR?” Shut up, I said what I said. You’re more recording data and experiments to make the first books and logs rather than make a record of history. Your beloved boyfriend is the one who gave you this task because he hates you. Jk. It’s because he doesn’t have enough hands to write everything down and conduct experiments at the same time so you have to do it for him.

Speaking of which, Senku is a certified yapper. Don’t let his nonchalant persona trick you, he’s anything but chill. If you also go off on tangents Gen is probably the one forced to break you both out of your excitement… again. (Listen they tried Chrome but he just joined in and Kohaku will not hesitate to beat both your asses so Gen it is. Poor guy lol.)

He’s not big on traditional affection, is what a liar will tell you. If anything you’re the one less prone to PDA. Now I say this but it comes with terms and conditions. Senku’s a busy guy, he likes to use his mouth–hold up–for giving instructions. So kisses are more rare. He also needs his hands for crafting, writing, just about anything really. So while he does like hand holding it’s a bit harder to get to. Which leaves y’all mostly just leaning against each other to show affection.

He does cuddle though. If it’s hot he’ll complain but that’s just because he likes to run his smart-ass mouth.

The villagers think you’re married already because you’re always beside him. And caveman laws. Senku won’t correct them.

Bonus: one day, he casually hands you something shiny and says, “This alloy’s rare. Only made it for one person.” That’s how you get your engagement ring—made from meteorite metal.

General

He’s incredibly observant, even when he seems distracted. If you so much as wince from a splinter, he’s already pulling out tweezers and homemade antiseptic.

Pet names are rare, but he sometimes calls you “Einstein,” “my lab partner,” or “miracle cure,” depending on his mood and what you’ve helped him with.

He won’t say “I love you” often, but he builds entire systems and tools just to make your life easier. That’s his way of saying it.

He builds you a custom gadget that only you can use. It’s completely unnecessary in the most loving way possible. Might even make it so on purpose just so you think of him, even if it is because of annoyance. Little shit.

Senku teaches you science constantly, even when you’re just trying to nap. He says knowledge is the ultimate gift. You say he is. He says you’re trying to distract him. You were.

When he works too hard and skips meals, you force-feed him ramen. He grumbles, but later admits you’re the only one who can make him willingly slow down.

You’re the only one allowed to mess with his hair. He pretends to complain but leans into your touch when you pull it back or wash it. Lives for your head scratches. Me too girl, me too.

He keeps small souvenirs of you in his lab coat—notes, dried flowers, a tiny bead you once gave him—and says it’s “just sentimental chemical bonding.”

Cuddles aren’t rare, but when he crashes from exhaustion, he clings like a koala and refuses to let go until morning.

He blushes like mad if you kiss him in public, but not because he’s shy—it’s because his brain short-circuits with affection.

If you get sick, he goes overboard researching herbal and chemical remedies, refuses to sleep until you’re better. Gets sick afterwards.

He gets quietly jealous when others impress you—then doubles down on his own projects to one-up them.

He lets you be the first to see every new invention, no matter how trivial. Your reaction matters more than the scientific community’s.

He absolutely remembers every important date (your birthday, anniversary, the first time you kissed). He’ll never make a big show of it, is the first lie he ever tells you.

If you’re sad, he gives you rocks that glow in the dark, handmade magnets, or funny contraptions to make you smile. Shiny rock theory anyone?

You once joked you wanted a robot. He built you one. It only says one phrase: “Senku says drink water.” Because he’s a petty asshole and you wouldn’t have passed out on the track field if you just listened to him! (Really trying to think of a Mecha Senku joke but I can’t. All I got is clang, bang, bang.)

He respects your boundaries like a contractual agreement. If you say “no,” he steps back 10 paces and documents your preferences for future reference.

You’re the only one allowed to tease him without being hit with a snarky comeback. He just smirks and says, “Tch. Fine. You win this one.”

Any inventions that might mildly convenience your life he will 100% make extra just for you. Like when he made a hair conditioner. (Shameless plug here, y’all should read my ‘Sun Kissed Science’ because it’s about him inventing sunscreen for you.)

If you cry, he freezes up, then offers you logical comfort “It’s a temporary emotional spike, we’ll regulate the cortisol levels.” Yes he does get better about this if it’s after petrification.

He teaches you math with rocks and sticks, and you somehow end up loving it because he makes it sound like magic. (That one Tumblr post that’s like “I told him to teach me about physics the same way he talks about poetry.” Or something idk I can’t remember.)

If anyone flirts with you, Senku swoops in with cold facts that thoroughly humiliate them. “You do know flirting with someone in a committed relationship is statistically foolish, right?”

When he’s working late, he lets you fall asleep in his lab, covering you with his jacket without waking you.

He grins like a devil when you match his sarcasm. He’s met his chaos equal and loves it.

He has a specific notebook labeled with your name. It contains sketches, formulas inspired by you, and a list of projects to make your life easier. It’s made of leather and crappy paper and love.

Gen called you “Senku’s moon” because he claims you’re the one constant that keeps his tides in check. He only said this to Senku but you’ll never know since he’s too embarrassed. He has absolutely threatened Genw ith manual labor if he spills.

You once called him “hot” during an argument, and he nearly walked into a tree. He denies it, but Kohaku saw.

When the two of you argue, it turns into a debate show. People bring snacks. You both win.

He secretly carved your initials into a spot behind the observatory, visible only when the sun sets just right.

He doesn’t believe in fate, but when you touch him, he swears his neurons fire in patterns he can’t explain—and that’s saying something.

@mylostleftfootsock im so sorry for the wait!

[complex-gods-96]

Senku headcannons with a health anxious partner!

~~~~

Senku just wants to help alleviate some of your stress, but ends up scaring you far worse.

Senku, who really just was trying to explain how unlikely it was that you would catch a cold from someone coughing nearby, but accidentally ended up rambling in about tuberculosis instead.

Senku, who wants to ease your anxiety but knows what too much about disease and accidentally ends up mentioning it at the worst times.

Senku, who eventually starts to catch himself and stops mid thought and instead switches to how useful medicine is.

Senku, who would keep an arsenal of cleaning products and medicine once things got more serious between the both of you. Absolutely determined to have anything to relieve your stress on hand.

Senku, who starts carrying disinfectant wipes on him so he can readily clean things if you start to panic about them being dirty and contaminated.

Senku, who likes to read up on advancements in medicine. He won’t tell you all about it, in case it triggers your anxiety, but loves to do the research so that if you ever ask he can be ready to spill knowledge

Senku, who understands your hesitation because honestly, people really are gross and full of germs. He can appreciate intense cleaning and avoiding illness. He didn’t want to get sick either

[moroniccats]

Gen and Taiju probably have the funniest offscreen dynamic. Taiju would just believe all the bullshit that Gen spews and he’d be torn between keeping the bit going and telling him the truth. Senku would be banging his head against the wall (affectionately) watching them try to communicate.
