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.

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.

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."

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.

Dr.Stone (Ukyo, Gen, Ryusui, Kohaku) x Reader Summary : In which you got social anxiety (anxiety in general) and the Dr.stone characters are here for you.

Warning : light angst, fluff, hurt with comfort, social anxiety, anxiety, overwhelming, overthinking, green flag Dr stone characters obviously, comedy (bit of humor)

NOTES : I myself had social anxiety so I tried to write this with my own experiences, if you think it doesn't correspond to social anxiety then I'm sorry it's surely because everyone has a different experience and lives it differently from everyone else! I write this with all respect of course and don’t forget that it always gets better in the end, never be ashamed of yourself or of needing help sometimes. (Sorry if this headcanons is bad, I’m not really proud of it I think I need to improve my writing)

Btw should I start writing for Sai NANAMI & Tsukasa SHISHIO ? I love those two characters and I usually write fast like 3/4 days but with those two more characters it will maybe take 1/2 days more, I would love your opinion ( •̀⤙•́ )

⿻ GEN ASAGIRI

The main workshop of Senku and Chrome was buzzing (or exploding) with newexperiment. Tools clattered around while Ryusui’s wild laughter echoed, and people swapped stories about the latest revival fluid success. You’d wanted to be part of it but the noise layered up quickly.. the voices overlapping with sometimes someone dropping a metal rod with a bang or a notebook on the floor.

Your chest tightened like a vice and you felt it that you needed to leave now. So you slipped away to a corner behind some supply, sliding down on the floor while trying desperately to calm the rising panic: It's nothing..I put myself aside for nothing, I could have participated in those story everyone shared so why didn't I go??

And of course Gen noticed your absence almost almost immediately, it’s his mentalist instincts he would say. He made his way over you.

 “Well, well~ What do we have here? My favorite anxious assistant having a dramatic meltdown behind the tent! The big bad workshop noises got to you, huh? Should I call for a dramatic rescue?”

His teasing supposed was light at first, meant to test the waters with humor seeing if your panick was real or could be easily calm down. But when he crouched and saw the real distress in your eyes, the way you were struggling to even speak, he dropped the act instantly.

 “Okay, okay, bad timing on the jokes. Come here, you.” 

He pulled a large and colorful piece of fabric from seemingly nowhere (maybe one of his many mentalist tricks) and draped it over both of you like a blanket. He created a small and silly private world that blocked out the workshop chaos.

“See? Now it’s just the Great Mentalist Gen and his favorite person. The outside world can wait.”

His voice suddenly turned gentle from a few minutes ago. He sat cross-legged across from you, knees touching yours for grounding

 “I know crowds drain you. Parties, big celebrations, even the ship’s lively nights—you pull away every time, and that’s alright. You don’t have to force yourself to it.”

And he spent the next hours at cracking softer jokes just for you such has silly impressions of Senku’s “science this, science that” rants, or poking fun at his own over-the-top personality. Then he suddenly opened up…

“Even I get overwhelmed sometimes pretending to be everyone’s favorite clown. But with you? I can drop the mask… so do the same around me..”

Gradually, your breathing evened out and you started smiling with Gen staying under the tent until you were ready, after all you guys had all the time you wanted because he casually announced to the group that you two were “on a top-secret mentalist mission” before he came to your rescue, so no one would press.

He always knew when to tease and when to comfort, and you never felt babied, just deeply understood.

⿻ ULYO SAIONJI

The expedition had been going well, at first…But everytime that evenings around a campfire arrived, it was always stressful..Even with just ten or less people from the Kingdom of Science that simply gathered.

That night Senku was explaining some new invention with Chrome excitedly interrupting, and a few others laughing at Senku face after chrome interrptued him.

The overlapping voices and crackling fire created a wall of sound that pressed in on you. Because even in this relatively small group, the social pressure lingered. Your mind kept scanning for judgment or for the “wrong” thing to say, eyes turning toward you if you stayed too quiet or spoke up. And suddenly your heart started hammering, the cup in your hands trembled, and you felt that familiar spiral: they are too loud, too many people around… I can’t leave now or they will see me…damn it, I can’t breathe properly. It will be embarrassing if they see me like this…

Ukyo’s sharp hearing caught it instantly—the slight hitch in your breathing, the way your pulse quickened. He didn’t make a scene because he knew it wouldn’t have helped. Instead, he stood gracefully, bow slung over his shoulder as if it were casual.

“I’ll do a quick perimeter check,”

While announcing this to the rest of the group his eyes was meeting yours, and with the smallest tilt of his head you understood he was inviting you along. 

You followed him away from the firelight into the darker, quieter woods. The trees filtered everything while the voices that surrounded you suddenly became distant murmurs.

Rustling leaves and gentle night insects was now the only thing you could hear. After a few minutes of walk Ukyo found a soft patch of moss at the base of an old tree and sat down, patting the spot beside him.

“I heard it, your breathing changed. Heart rate too. You don’t have to explain if you don’t want to.” 

He kept his voice low has if he was scared to be too loud. One arm came around your shoulders, warm and secure. 

“Just breathe with me for a bit...”

You leaned into him, focusing on the rise and fall of his chest. Minutes passed in comfortable silence broken only by the forest. It's comforting... to switch to a huge noise to a calm noise of nature, filled with cricket noise and just the soft breath of Ukyo.

”Are large groups are tough for you? I’ve noticed it before, at the village gatherings or on the ship deck when everyone’s celebrating. It’s okay. The world doesn’t need you smiling through it every time.”

He stayed with you long after you calmed, sharing quiet stories about how he used to find peace in listening to the ocean’s subtle sounds instead of crowds because he too with his incredible earring could make everything or everyone around him too suffocating. He could understand you better than anyone.

”If it ever gets bad again, just look at me. I’ll always hear you first. I don’t mind being the one that ask to leave first..”

”Thanks Ukyo…it means a lot too me”

And by the time you both returned the group had quieted down naturally. And when you sit next to Ukyo, you told yourself you were thankful that he never made you feel like a burden because of your anxiety..

⿻ RYUSUI NANAMI

The Perseus was glowing with lanterns and excitement from everyone. Ryusui had been talking about the casino after losing to Senku earlier. Cards, dice, betting on ridiculous moves, simply the thrill of victory. 

And honestly it worked, the deck was packed with laughter,  Chrome yelling excitedly then crying minutes after because he lost all of his dragos, and others joining in. Ryusui was in his element, eyes sparkling as he prepared to declare the “greatest gamble of the century.”

Then he saw you lingering near the edge, away from the lights, arms wrapped tightly around yourself. It looked like your mind wouldn’t shut off, you were expecting conflict or anything bad that could happen leaving you on edge. Your face was pale, eyes flicking nervously across the growing crowd. The noise, the people, the energy—it was all too much, and you were already starting to spiral: Okay... it's okay I just need to breathe…, at worst I'll just go to François's bar? Wait no, what if someone is too drunk and decided to take a fight with me.. maybe If I manage to not interact with anyone it should be fine...

But Ryusui didn’t hesitate. 

“Hold it right there, everyone! Casino can survive without its greatest captain for one night. There are more important treasures aboard this ship.” 

And at first you didn’t  understand why he shouted that before he held your firmly while steering you away from the festivities toward a quieter upper deck where the ocean waves provided a soothing rhythm instead of voices.

He settled beside you against the railing, the starry sky vast overhead. 

”Ryusui…you shouldn’t be here, the casino is waiting for you, you kept talking about it to me for day!!”

“I was looking forward to it,” 

Well atleast he was admitting honestly…making your head fall down.

”But not if it means leaving you like this. Your comfort comes first—always.” 

He finally finishes his sentence, he then taking your chin in his hand and lifting your face. Because Ryusui might be greedy and loud but his affection for you ran deeper than any thrill.

So He stayed right there, talking in a lower, calmer voice than usual, sharing old stories of his sailing days and how he wished you both would get vacations after all this shit. 

The vastness of the sea made even big crowds feel small by comparison. Maybe that why you liked it so much. 

“We can go somewhere even quieter if you want. My cabin? Just the two of us. Or we can stay here and watch the waves until your heart slows down.”

Hours passed comfortably. The casino noise faded into the background and Ryusui never once complained or rushed. He told himself that is excitement could wait—your peace was the greatest treasure.

⿻ KOHAKU

The training grounds had turned lively after a big group celebration nearby spilled over. Warriors and villagers mingled with voices louder then sharing stories and giving friendly challenges.

And honestly you did tried to stick it out for Kohaku’s sake, but the press of people and constant movement overwhelmed you fast. The celebration was meant to be relieving, but for so why did you act like that?? Even outside of immediate danger it seemed like your mind stayed hyper-alert, scanning for social missteps or hidden threats. The constant “what if they notice I’m off” didn’t helped. So you retreated to the far edge of the clearing, sitting on a fallen log as your breathing turned shallow and your hands wouldn’t stop shaking: If the Warriors ever saw me like that they would surely laugh at me…I panic for so little, come on you are a fighter so recover fast..

Meanwhile Kohaku found you within minutes, probably her sharp instincts guiding her. She didn’t fully understand why big groups triggered this for you because she was comfortable in crowds, thriving on energy and action but right now that didn’t matter. She simply sat down beside you, close enough that her shoulder brushed yours.

“You’re doing that thing again…The shaking and the quiet breathing. I don’t get what exactly sets it off every time… too many people? The noise?” 

”….”

”I mean… I don’t need to understand it all, but know that I’m always there.”

And Without asking she wrapped a strong arm around you and pulled you against her side, her warmth and steady heartbeat grounding you. She stayed like that, solid as a shield. 

“You don’t have to go back. I can tell them to quiet down or we can leave entirely. I’ll fight off anyone who tries to drag you into it.”

That make you laugh, imagining Kohaku fighting for people to be silent. And when you started to calm down she offered comforts to you, getting up to get water rrop a nearby river, suggesting light sparring just the two of you to burn off the anxious energy or just sitting in silence watching the sunset paint the sky.

“We can train together tomorrow, just us, or explore the quieter parts of the island?? Wait maybe you want us to stay there instead..Whatever helps.” 

She might not understand it at all because her energy never drain around people but she always try her best to be around you even calmly. She might tease you lightly later about being tho, but never in a way that dismissed your feelings. 

Kohaku ls always there and is always reliable, protective, and ready to stand by your side no matter what and those moments showed how she would always take her time with you even if she doesn’t understand it.
