“hello?” you groggily answered the phone. it was one in the morning, and you were wrapped up in the warmth your comforter,
“I’M SO GLAD YOU PICKED UP,” itadori’s panic blasted from the other end, “PLEASE HELP ME!”
you jolted upright with worry, “hello?? what’s going on? are you okay?”
“it’s megumi!! he’s-” he choked on a sob, “he’s being weird.”
“what? why? calm dow-” itadori’s scream interrupted you, followed by a loud whack.
“okay. i knocked him out.”
“oh my god. can you please explain what’s going on?”
“megumi is trying to fuck me.”
you gasped, “what??”
“hear me out. basically gojo sent us out to fight this cursed spirit; which by the way, it was one hell of a mission. i swear we were fighting that thing for hours, just for it to escape!! and then-”
anxious, you interrupted him, “yuuji. get to the point.”
he pouted, “right, sorry. so, the curse was located at a brothel, and we found out that the prostitutes they offered were all human trafficking victims.”
“oh my god. that’s awful.”
“i know right? it was strong as shit. nothing we couldn’t handle, of course, but... " he took a deep sigh, “right as we were about to land the finishing blow, the curse got to megumi.”
“huh?? why are you calling me?! call shoko!!”
“uhm, i don’t this is something shoko can help with. he’s… physically fine. he’s not hurt or anything.”
“then what’s wrong with him?” you asked.
itadori nervously kicked some pebbles on the ground while debating his next choice of words. “uhm… i think the curse made him super horny.”
your brain stuttered. after a moment of silence you crack up.
“this isn’t funny! he’s grabbed my ass twice already!” he whined.
laughter turning hysterical, you clutch your stomach tears pricked your eyes as you tried to compose yourself. “so, what do you want me to do about that? i hope you’re not expecting me to fuck it outta him.”
“no! that’s not what i’m saying; well actually that’s one solution… but i’m just traumatized! i don’t want to see anymore horny megumi.”
you giggle, “what makes you think i want to?”
“can you just… lock him in your bathroom or something? maybe throw him some water and food every couple of hours?” he said, desperately.
no longer groggy, you agreed, “okay fine.”
“yes!! he cheered, “i’ll be there in 20.”
｡‧ 𓆝 𓆟 𓆞 ·｡𓂃 ｡
itadori knocks on your door, carrying a passed out megumi over his shoulders.
“you look rough,” you comment as you motion him inside.
he kicks off his sneakers and huffs, “thanks. this is my ‘fighting a sex demon’ fit.” he places megumi onto your couch and plops himself down next to him.
you sit next to him with an energy drink in one hand and a bag of chips in the other. handing them to itadori, you examine megumi’s state. he’s relaxed, sitting with his face leaned on top of the back cushion. his chest rises and falls with slow breaths.
“he’s out cold, huh?”
he cracks open the redbull and downs it in one go. you guys conversate hushly. itadori explains the mission in detail, like the curse’s abilities and how other than killing her, sexual intercouse was the only other way to break the curse.
while he rants, his phone rings.
“hold on, it’s gojo,” he answers the phone. gojo’s loud whines cause itadori to wince. he replies mostly with ‘mhms’ and ‘bruhs’.
hanging up the phone, he sighs, “dude, gojo’s girlfriend broke up with him.”
“again??”
“yeah, said he called everyone and i’m the only one who picked up.”
you stifle a laugh, “that’s so sad.”
“well, i’m gonna go comfort him before he jumps. i’ll finish the mission with inumaki tomorrow morning. call me if anything goes wrong.“
he finishes his goodbyes, snatches the rest of his chips, and steals another energy drink from your fridge.
after his exit, you return your attention back to megumi, who’s still slumped upright on your sofa. gently, you try pushing him to lay more comfortably.
while his body slowly tips, you realize you misjudged his height.
before you can stop it, the impact of his head against the coffee table halts the otherwise soft descent.
“oh shit.” you curse.
he blinks.
“hey. sorry i woke you. you can go back to sleep.”
he scans his surroundings before freezing at the sight of you. there’s an inch of silence before he abruptly pounces.
he leaps off the couch, seizing you by the waist with one hand and cupping the back of your head with the other.
“megumi! stop! you don’t know what you’re doing!” you push against his chest. despite your attempts, he squeezes tighter, pulling your face flush against his chest.
he turns, maneuvering you along with him, and slams you back onto the couch. before you could protest, his lips lock onto yours. his hand, still latched to the back of your scalp, makes any attempt to escape futile.
you fight back, keeping your mouth sealed and turning away every time he closes in.
his breathing’s irregular. you know he can’t control himself.
you know it’s not him.
the boy who held your hair back on your 21st.
the boy who comforted you after your first break up.
the man that watched you cook ramen so he could learn to make it the way you like it.
how you like the noodles just slightly undercooked because it’s chewier.
how you add in the toppings last because it adds more of a bite.
but maybe it was still him, just a side you haven’t explored yet. and maybe, it’s time for an adventure.
“megumi, it’s me. snap out of it!”
his eyes flicker, countless emotions running through his oceanic irises.
he struggles to hold himself back. guilt and worry flash through his face before he strangles out, “fuck. i-i’m sorry.”
you bring a hand to caress his jaw. “hey, it's okay. i know. i understand.”
though megumi was still under the control of the curse, his restraint showed through to you. even when his mind’s clouded with layers of haze and disorient, he was fighting it.
and what kind of best friend would you be if you didn’t help out in his time of need.
it’s only fair, right? after all he’s done for you?
with big eyes, you tenderly look up, “if it’ll make you feel better, i can help.”
and that was it. all signs of restraint vanished as he crashes into your lips, and this time, you welcome it. your mouths move in harmony with little gasps of breath between pauses.
his hands scale your figure, squeezing and digging his fingers into the plushy curves of your waist. he squeezed with purpose, with intent. there’s just enough pressure to where you couldn’t describe the feeling as painful, but it still hurt, enough to where you’re flinching and shying from his touch.
and it felt so, so, good.
he intertwines your tongues for one final swirl and detaches with a deep breath. he hovers over your hair a spiky mess, lips swollen, and eyes dark with a crazed obsessive glaze.
beyond the lust, megumi’s able to admit one thing. “you’re so pretty.”
simple words, but your guys’ relationship never called for compliments. it catered more towards actions, like tucking a flipped tag on a shirt, or grabbing an extra straw for the other when getting take out.
flustered, you turn away in embarrassment, but he dives back in. megumi licks a stripe along your earlobe, sending goosebumps across your arms.
he continues downwards, submerging his face into the corner of your neck. his hair tickles your ear, but the feeling is overwhelmed with the sting of marks he leaves.
“mmm! not where people can see.” you protest.
still focused on his task, he mumbles a dismissive “kay.”
one of his hands is on your waist and the other unbuttons your pajama shirt. the suction of the marks continue, adorning your neck, collarbone, and eventually your chest.
he kisses your sternum as if it were the final deterrent. then, his lips connect hungrily onto your nipples, swirling his tongue, flicking, and nibbling at the hardened bud. every now and then he would change the flow by biting down with enough force to coerce an instinctual yelp.
and every time, you pulled him in tighter.
the more he teased, the more frustrated you became. “you don’t,” you breathlessly gasp, “have to do that.”
he begrudgingly detaches and then grabs you by the waistband of your pajama shorts. megumi twists your body; where your shoulders laid on the backrest of the suede couch, and the balls of your feet secured your posture at the ends of the cushion.
already maneuvering himself off the couch, he rests his body and knees on the carpet and kisses the bare of your inner thighs.
you exhale sharply in anticipation, the whole situation now fully registered in your mind. it’s not like you haven’t imagined yourself in this situation. i mean, your best friend is a fucking stud.
and to be frank, he’s totally your type.
lean, defined, muscular.
beautifully long lashes.
perfectly messy hair.
you feel excited. like those wine nights filled with confessions and sexual tension had finally come to fruition.
wait, no. you’re doing him a favor. he’s the one under an uncontrollable curse right now.
you snap back to reality when he hastily rips your shorts off and snakes down your body. exposed and vulnerable, the only thing keeping his face from your heat is a flimsy string of fabric.
megumi pulls aside your soaked thong, letting it catch on your puffy lips and groans at the sight. he wastes no time, sliding two fingers up your slit and parting the tender folds at the hood. his face disappears between your thighs as his tongue makes contact.
he’s lapping at your clit thirstily, like he just ran a marathon. your nerves short circuit. your fingers tightly weave into his surprisingly soft locks, tugging and pulling for mercy, but it does nothing. rather, it only encouraged him further.
he slips in two slender fingers. though, he’s not earnestly thrusting. if anything, he seems to be exploring. running his fingers along the crevices of your entrance, he traces the spongy part inside you and curls his fingers. his eyes are glossed, purely fascinated with the way your walls pulse for him.
he’s feeling your cunt like it’s braille, reading it like a heartfelt confession. the longer he explores, the more the sensations build.
your stomach tightens and hoarsely, you call out his name. it’s whiney and high pitched, almost begging.
to that, he laps faster, flattening his tongue and applying precise pressure to your sensitive bud.
no matter what you say, he just keeps going at his own pace. the words don’t get through to him, like he’s busy diverting all five senses to your pussy.
finally, you feel yourself tipping over the edge. your walls tighten, anticipating ecstasy. one of your hands gripping wildly at his hair, and the other squeezing your breast. right as you’re about to reach your peak, he abruptly stops.
he removes himself from between your thighs and wipes his mouth on his sleeve. megumi licks his lips, cleaning the rest of your juices and shakes his uniform off.
the sight of his long, toned, and lightly scarred torso, spun you deeper into a lustful spiral. though he put no effort into flexing, the abdominal muscles still proudly rippled through his core.
blinded with desperation, you lose yourself. “megumi please… i need it.”
you reach to grab his shoulder, trying to pull him back down, but he catches your hand midway.
“shut up.”
grabbing both your wrists, he pins them intertwined above your head. with his other hand he angrily tugs at your underwear.
instinctively, you lift your bottom and point your toes to help rid the fabric.
now fully naked, you wait impatiently for his next action. your hands are still tightly locked above you, and all he’s doing is staring. his eyes scale from your cloudy eyes, to your lips, and down to your waist
“more please. i need you.”
“i said, shut up,” he raises a hand and lands a rather harsh slap on your tits. the skin around your areola slowly turns pink, matching the shade of your abused nipples.
you curse as the pain sends heat dripping down your thighs.
unexpected. but, fuck, this is a side you’ve never seen of him. the usual calm and gentle megumi, now uncharacteristically assertive.
he steps out of his pants, bulge peeking and intimidating. it slaps against his stomach as the black boxers are pulled off.
speaking of uncharacteristic, he’s big. i mean you guessed it’d be long from his height, but circumcised? thick? curved upwards?*
your pupils dilate, eyes wide and begging.
“be patient. i’m gonna give you what you want.”
he angles his cock with a thumb at the base, circling the tip around your entrance and smearing your arousal down his length.
“look at you. spread like a fucking slut.”
you can’t even say anything back. he’s already forcing his way in. you’re screaming. all the wetness you produced did nothing to dull the throbbing pain at the rim of your entrance, but he doesn’t stop till the tip is fully settled.
nails clawing at the material of the sofa, you clench your core, trying to push him out. “i-it hurts! it's too big!!”
he grits his teeth, “if you don’t relax it’s gonna hurt more.” despite that, he keeps inching himself in. at first it’s slow, but by the time he’s halfway in, a switch is flipped.
still whimpering below him, he forces the remaining length in one harsh move.
“fuck! megumi!” your body squirms, attempting to flee the sudden intrusion.
he places a large hand at your pelvis to still you and starts thrusting at an aching pace. you feel him slowly pull out before slamming back in to the hilt.
your hands scramble to his forearm, begging to be released, but the pressure is firm. he’s panting and locked at the sight of your tight hole clinging and accommodating to his girth.
voice strained, he muses, “all that whining, but look, you’re sucking me back in.”
and he’s right. you’re downright stretched beyond repair, molded to fit his every vein and before you know it, the screams change. your mouth’s parted and speechlessly gasping every time he bottoms out.
your dim living room’s filled with filthy, sloppy squelches and indescribably dirty, sinful skin slapping.
his dick probes at the sweet spot inside you causing you to dig your nails deeper into his arm. “more. faster,” you incoherently blabber, “megumi, please. need you. i need yo-”
slap.
face slanted from the recoil.
the sting on your cheek.
his possessive glare.
your mind fucking shatters. the orgasm hits harder than any other sensation you’ve ever felt. every nerve in your body is on fire. you’re convulsing and violently twitching. messily and uncontrollably gushing around his cock, and all he does is piston faster, harder.
your reactions aren’t overlooked. rather, they’re studied like a bible. megumi is obsessively worshiping every moan, every tremor, and every tear that falls from your face.
every thought you ever had before this moment vanishes. instead, it’s filled with blinding regrets about not taking your best friend’s dick sooner.
he’s laughing. “fuck. you really liked that, huh?”
his grip moves to the dips of your pelvis. he pulls your body downwards and lifts your ass until your spine’s arched to its limit. from this angle, your back and head is resting on the cushion with your torso stretched while your entire lower half is literally at the palm of his hand.
he pounds into you animistically, chasing his own high. completely fucked dumb, you’re limp, crying, and completely in his control. eventually, he loudly groans, driving his dick the farthest he can force it, and spills his hot seed into you.
you feel his cock head pulse and the veins throb while he’s stilled. the muscles on megumi’s arms twitch, tensed from the orgasm. his hands squeeze tightly at your hips, digging harshly into your bones.
yeah, that’s gonna bruise.
he slowly pulls out, watching the cum seep around the length. he’s dragging it out all the way, letting your mixed fluids leak from your hole, scooping it with his sensitive tip, and shoving it back deep inside.
dazed, he coos, “hey, you worked hard for this. don’t waste any, kay?”
just as megumi’s able to stabilize his breathing, he freezes. he curses a dragged out, “fuuuck.”
you look down, blinking away the tears, and see your taut stomach with a soft bulge protruding the middle.
for some reason you’re embarrassed. maybe it’s from his astounded expression, or maybe you’re finally realizing how vulnerable you are, but your hands move to cover the bulge.
“i already saw it, what are you trying to hide?”
huh?
his tone changed.
you raise your line to sight to meet his eyes as a final confirmation to your theory.
yep. he’s back.
half complaining, half relieved, you whine, “megumiiiiii!”
cock still inside you, he chuckles, “thanks, for helping me.”
you cover your face, “whatever. get the hell out of me now.”
“aw, really? you seemed to like it so much though.”
he gives one final thrust before gently exiting you.
you both sigh at the separation. he holds himself on top of you, kissing fond pecks on the top of your shoulder.
he whispers, “no, for real though, thank you.”
“mhm.”
he nuzzles closer, snaking his arms around your waist.
“can we,” he hesitates, “can we do this again? maybe without a curse?”
you wrap your arms around his back, rest a hand on his head and giggle, “we’d be stupid not to.”
he chuckles, gently squeezing you in celebration.
“plus, you probably would’ve fucked itadori if it weren’t for me.”
no response.
“he told me you went for his ass twice.”
silence.
“megumi?”
“i don’t remember that.”
humored, you tease, “really?”
“nope.”
"reallyyyyy?"
“shut up.”
yeah he definitely remembers.

senku who gets jealous after misunderstanding your feelings. he’s pouty and annoying, so you confront him, spiraling things into something more heated.

part 1 part 2
can be read as a stand alone too :3
it’s been a week since you and senku’s so-called experiment. things are not normal. senku acts different around you. he’s still cocky, snarky, and a smartass but, something’s different. he’s avoids eye contact and is way more pouty around you.
for example, three days ago, you were looking out with kohaku on top of the crows nest.
shamelessly gossiping, you laugh, “there’s definitely some unresolved sexual tension between ukyo and ryuusui.”
kohaku giggles, “ryuusui has sexual tension with, like, half the kingdom.”
you both burst out hysterically, smacking and shoving each other. laughter dying down, kohaku asked a hypothetical, “so if you could hook up with anyone in the kingdom, who would it be?”
blushing, “you first.”
“probably either luna or hyoga. mask stays on though.” humored by herself, she looks at you expectingly.
though the answer is bright as day, you whisper, “uhm… for me, probably senku.”
kohaku leans closer, “girl, speak up.”
face getting hotter, you mumble even quieter, “sen…ku”
something shatters from below. you both peek over and see broken glassware.
“who dropped this!? pick it up, asshole, it's dangerous!” kohaku jumps from the post and sees senku scampering away.
“senku! clean this up!”
“i’m busy! ask chrome!” he yells back.
you climb down the ladder after kohaku, “what was that all about?”
“probably a scientific breakthrough or something.”
· · ─ ·𖥸· ─ · ·
that night on the ship, the crew gathered for dinner. you, kohaku, francois, and the five generals sat at the same table. as usual, it's lively and rowdy.
excitedly bouncing around senku, chrome exclaims, “so then i thought, what if we used a rotor and attached some blades to it. then when it's windy, the blades will spin the rotor, which can be used to power the generator!”
gen snickers, “well it’s still impressive that he thought of the idea himself.” the rest of the table hums in agreement.
finding your food needing an extra kick of flavor, you reach for the salt. realizing it was at the other side of the table, you call out, “tsukasa, will you pass the salt please?”
“of course.”
before he could grab the salt, senku’s voice rose, “i’m next to the salt too.”
the table quietens.
you break the silence, “what?”
“well i’m just wondering about the thought process behind your choice of action. you asked tsukasa for salt when i was also next to it. is tsukasa more qualified for condiment passing than me?”
“uhm, you were mid bite.”
“oh okay.”
the silence prolongs.
gen chirps, “right. so anyway, can we do something about the broken floorboard in my room?”
· · ─ ·𖥸· ─ · ·
the next instance was that same night
after a rough storm, debris and seaweed covered the ship. you help by sweeping. singing a tune from before petrification, you navigate around corners and swerve under tables. tidying up smoothly, until some barrels block your way. you tried lifting it yourself, but they were filled to the brim with beer.
scanning for anyone in the power team, you see tsukasa loitering around the quarterdeck. “hey! tsukasa, can you help me lift this keg?”
senku, who was in the captain's cabin, bursts out. he pats tsukasa on the shoulder, “it’s okay, bud, you rest. let me handle this.”
he struts over, side eyeing you on the way, and squats to grab the bottom of the barrel. you wait patiently with the broom in your right hand. senku tightens his grip around the bottom and lifts.
the barrel doesn’t budge.
he tries again, grunting this time.
the barrel stays.
he lifts again, heaving.
exasperated, he stands back up, pinky in ear, “if we tied a rope on both sides, we could attach it to a pulley system and potentially-”
feeling a little bad, you cut him off, “no, you know what, it's okay. there can’t be that much dirt under there.”
“you don’t think i can do it? is tsukasa more qualified in barrel lifting?”
“what..?”
· · ─ ·𖥸· ─ · ·
the third time is when you snapped.
you’re perched over the edge of the ship, fishing rod in one hand and the other on the rail. you enjoy in the cool ocean breeze combing your hair. serene, eyes closed but then- a tug.
your whole body snaps awake. you jump and immediately start reeling. pulling, then reeling, then pulling again. the fish suddenly jerks causing you to stumble over your feet and tip over the wooden rail.
you fall into the water. dropping the rod, you thrash and flail your arms. your limbs lock up in the cold and before you know it, you’re sinking. (author can’t swim)
then, you feel large, strong arms dragging you.
now back to the surface, tsukasa holds you steady against his chest.
he sets you back down, “i heard a splash and came to see what it was.”
you cough up the remainder of the ocean water, “god thanks, i almost died.”
a group forms around you, all questioning your well-being. from the corner of your eye, you notice senku with a half-inflated donut in his arms. he stares at you, eyes filled with an indescribable emotion, before turning around and retreating below deck.
you quickly get up, pushing past the crowd, you dismiss their worries and yell out, “i’m okay, i’ll be back.”
you run down the stairs, straight to his lab.
a knock, “senku?”
you creak the door open. peeking inside, you saw senku hunched over his desk, seemingly immersing himself in his work.
you think of an excuse to talk to him.
“hey, i was hoping you had some towels down here?”
“why don’t you ask tsukasa?” he quickly retorts.
you feel a surge of anger welling up in your chest; what the hell is wrong with him?
attitude lacing your words, you spit, “what’s up with you lately?”
crimson eyes still locked to the papers, “i don’t know what you’re talking about.”
“i almost just died, im soaking wet, and im cold. some words of concern would be nice.”
he stays silent.
“and why have you been one-sidedly competing with tsukasa recently?”
he slams his pen down and swivels his chair to face you. “because you like him.”
“where the fuck did you hear that from?”
senku glares at you, “i overheard your conversation with kohaku.”
you cock an eyebrow.
he continues, “you know ‘if you could hook up with anyone’.”
oh my god.
“senku i think there’s a misunderstanding here. it’s not true. why would you even believe that?”
he rolls his eyes, “because statistically it makes sense. tsukasa is the opposite of me. why would you pick me over a 6’5 gentle giant? biologically, you’re bound to be drawn to him.”
“statistically and biologically, you’re a dumbass. i told you i liked you, and you did the same. that’s it. any other questions?”
he snaps his head to face the wall, “liar.”
about to crash out on him, you open your mouth before you notice something.
he’s blushing!!
a grin widens, “senku.”
“what?”
“you’re jealous!!”
“no i’m not! i’m very secure with myself. i’m smart, like really smart, why would i be-”
you interrupt him with a squeal and jump onto him, straddling him in his chair, “gah!! you’re so pouty when you’re jealous!”
“i’m not jealous! get off of me, you’re soaking wet!”
your hands frame his face, “i like you so much, senku.”
flustered, he counters, “but i don’t think you like me to the extent that i like you.”
“that’s so not true-”
“it definitely is. before we, you know, did the deed, i rewrote as much information as i could remember from the female anatomy textbooks i read prepetrification, with illustrations by the way.”
he takes a deep breath, then continues his rant, “all because i was scared i couldn’t fuck you right. and clearly you didn’t like it because you said you wanted to hook up with tsukasa right after.”
head spinning and face on fire, you shut him up by slamming his lips onto yours.
“mmph!” he tries to push you off, but immediately melts into your taste. he makes an attempt to stand up, but you push him back down aggressively.
molding your chest onto his, you direct his hands to your hips. tongues fighting with needy passion, your arms snake around his neck.
senku grapples your hips and grinds them down, mashing your core onto his growing manhood.
breathily separating yourself from him, “are you convinced now?”
he longingly sighs, “yeah, i’d say so.”
giggling, you rise from your position and turn. “well i’m going to head back up. i need some towels from tsukasa. maybe they’ll be used too, if i’m lucky.”
approaching the door, you reach for the handle before senku slams it back shut from behind you.
“you think you’re so funny.”
you give him a sly look, “who says i’m being funny? what if i want a tsukasa towel?”
“tsukasa’s towel can wait,” senku muses. he moves closer, “i need to check on my subject. you know, for any lasting side effects.”
you roll your eyes, “well my back still aches, my vagina hurts, and both my ego n’ wrists are bruised.”
he tucks a stray strand of hair behind your ear, keeping his fingers light on your jaw. “sorry, can i help with that?”
knowing where this was headed, you gulp. “… trial two?”
locking the door, he whispers, “such a smart girl.” your thighs rub at the praise.
senku pins you against the door and collides your lips together. hands scaling your skin as he takes control of your mouth.
he tugs at your dripping clothes, “let’s get you out of these?”
“mhm,” you purr into his lips. you slowly peel off the layers, finally free of the sticky garments.
he picks you up by the legs and drops you onto his mattress. the warmth of his bed comforts your chilled body, sending goosebumps down your extremities.
senku sits on the edge of the bed, feet planted on the hardwood, and motions for you to get closer. you slowly crawl over until you’re next to him.
he gently slides a hand behind your waist and licks at your neck, sending shivers down your spine. while he showers your skin with affectionate kisses, you eye his erection; rock solid and aching for attention.
you extend your palm towards his tent, but senku stops you.
“punishment first.”
you laugh a little, “punishment?”
completely serious, “is this funny to you?” he scoffs, “over my knee. now.”
a part of you wants to test his patience, but the other part of you is leaking down your thighs. you obediently lie your stomach down on his legs and prop your elbows on his mattress.
he kneads your cheeks, “did you like asking tsukasa for help?”
“maybe i did, what about it-”
SMACK
a loud slap reverberated off your ass.
immediately, you complain and twist your body, “ow! senku? what the fuck?!”
he holds you down with his left hand. senku asks again, “did you like asking tsukasa for help?”
“no! i didn’t!”
another smack. pain sears through your bottom.
“what about when he carried you out of the water? did you like being in his arms?”
tears welling in your eyes, you cry out, “he was just helping me. i don’t like him!”
he raises his arm again, this time higher. he sends it down with twice the force.
“stop! it hurts! i’m sorry!” you whine.
he doesn’t stop.
senku sends countless strikes in a row, as if he were releasing his jealousy over your peachy cheeks.
your sobs and screams only encourage him.
“you say you want me to stop, but,” he slides a thumb between your folds, “it’s a mess down here.”
he caresses your flaming red bottom, “should i plug you up?”
helplessly shaking and vision glossy, you utter, “please.”
senku sternly spits, “get on the bed. face down.”
you wobble off his thighs and plant yourself on his bed, wiping your tears on his sheets. you hear the rustling of clothes dropping and then feel a dip in the mattress.
senku perches behind you and places both hands on your hips, and lifts you until you’re spread before him.
back arched and legs wide, the cool air blows across your sticky folds.
“stay still, don’t look, and you’ll get what you want.”
god.
he gets off the bed. you hear drawers opening and closing, as if he were searching for something. glassware, clinks and steps approach. finally, you sense him nearing.
he returns to his spot behind you. he blows a cool breath on your slit.
your nerves are on high alert. then, something cold probes at your entrance.
you cry out, but he continues pushing it further in.
your breathing staggers, “senku! what’s happening?!”
he chuckles, “calm down, baby, it’s just a test tube. don’t worry, i disinfected it.”
the test tube continues easily sliding into your wet opening. it’s not thick, but it’s long. he doesn’t stop until it settles fully inside you.
“y’know, i’ve been itching to try this since last time. i can feel it, sure, but to see inside? that’s a whole different study.”
to see inside??
senku wasn’t just trying to pleasure you. he was curious. he had a light propped up behind him, shining into the clear of the test tube.
it stays like that for a while. him just entranced by the squeezing of your walls around the tube, the slick dribbling down your thighs, your needy whines.
eventually, he rubs your clit. it’s a gentle pressure, but you were weak from the teasing. you bite your lip, trying to contain the sounds.
then he rubs faster.
he goes in fast circles, as if he were trying to polish your bud. your moans increase in pitch and frequency.
senku condescendingly laughs, “look at your walls gripping this thin little thing. do you like it that much? you’re practically drooling over it.”
too embarrassed to say anything, he takes that as a sign to start pulsing the object in and out of you.
your legs shake at the sensations.
“holy shit. i can see everything.”
he angles the tube down, straight to the spot that makes you crazy.
“this is where you like it, right?”
“stop! senku!” tears brim in your lids.
he lands another strike on your ass. a sob breaks from your throat.
“careful what you wish for. you want this.”
unable to deny, you grip the sheets, letting him have his way.
“shit,” he strangles out.
the cold tube now warm, he completely withdraws it from you. you hear it clang on the ground. before you could whine in protest, something bigger sinks in without warning.
orgasm immediately coursing through you, a scream belts from your cords.
he doesn’t go easy. he plunges in and out harshly, angrily, drunk from the squeezing and spasms.
the stretch hurts, but you find yourself drowning in the overwhelming pleasure.
“right there, wait no, i can’t- senku!” you’re blubbering nonsense at this point.
he deals another blow to your backside. pain and pleasure coursing through your veins, your mind fogs.
a low groan graces your ears. senku’s thrusts break rhythm, signaling his soon release. but as he’s about to, he pulls out, breathing heavily.
“w-why?”
eyes hazy, senku rasps, “cause i’m not done yet.”
he pushes you to your side and swings your right leg around his shoulder. straddling your left leg, your body weight disperses unevenly over the soft mattress.
senku thumbs his shaft downwards and slowly slides his length between your folds. not yet inserting, he focuses his tip on your clit and repeatedly rubs back and forth.
your eyes are clamped shut, feeling the jolts of bliss coursing.
then he pushes in.
the new position allows him to thrust deeper; harder. he slams in, balls slapping against your cheeks.
senku aims for your cervix, knowing the pain it could cause, he gauges your reaction. when your expression melts, and your moans lengthen, he hits harder.
your toes curl as you reach your next peak. walls wrecked around his length, and a white cream rimming the base of his cock.
you don’t moan. you’re holding your breath, as if bracing for impact. though, your body violently shakes, a tell-tale sign of your orgasm
senku finds himself approaching his own orgasm, but yet again, he pulls out.
completely fucked dumb, you ramble, “please. no! i’m done, i can’t do it. finish already! i’m sorry!”
loving your desperation, he smirks. “if you want me to finish so badly, do it yourself.” he plops down on the bed, leaning against the headboard, and motions you above him.
you mumble a meek “okay.”
legs quivering, you weakly position yourself above him. you palm his length as it’s flush to his stomach.
senku exhales sharply. you forget he’s denied himself of two orgasms.
it’s sensitive.
whimpering, you pick up his heavy cock and align your core against it. placing your hands on his lower stomach, you stabilize yourself over him.
you slowly sink him into your sensitive hole. smoothly entering with the lubrication of your previous peaks.
senku whispers a long, drawn-out, “fuck,” as you lower yourself onto him.
once fully settled, you start to move. lifting yourself all the way to the tip, before plummeting yourself flush to his pelvis.
senku flicks his vision to your face as a sob breaks. you’re crying. tears streaming down your face as you desperately ride him.
he stifles a groan, “god. baby, you look so,” he stutters, “so fucking good.”
you ride him until your legs burn, losing your rhythm.
“need some help?”
you can’t even answer because he’s already clutching at your waist.
it’s brutal. he’s snapping his hips at a torturous pace. all you can do is hold onto the headboard behind him for dear life.
finally, his breathing falters and his pace hastens. senku plunges in one final time, face buried in your chest and arms wrapped around your waist.
with a low groan, he releases hot ropes of cum deep inside. just thankful it was over, you savor how full you feel.
your chests heave as you look into each other's eyes. senku softly pecks you on the lips, “was that okay? are you alright?” he pulls out, seed following on the way out. it gushes out of you, dripping from your core, to your thighs, to staining his gray sheets.
your head flops onto his shoulder, “other than the fact that you came inside, it was mind-blowing.”
he tightens his grip on you and chuckles into your neck, “i’m sorry. chrome and i can tackle levonorgestrel as our next project.
senku wants a human lab rat, but what could he be testing that required you to be tied up naked on his bed??

chills down your spine. senses on high alert. the feeling of smooth rope wrapped around your wrists. a bush of green hair enters your field of view. senku, who’s perched over you, is messing with the knot on your left wrist.
you’re lying on your back; bare skin flush to the bedding beneath you. arms constrained, with your hands above your head to the frame of the bed.
on your left there was a nighttable with what seems like a bunch of lab tools neatly lined. something stood out though. you squint.
is that a condom?
“senku, i don’t know about this.” you hesitantly confess.
senku reaches into the right pocket of his lab coat, pulling out a folded sheet of paper. “but you already agreed.”
he extends the now unfolded paper towards you. at the top in big letters “consent form.” and at the bottom in black ink, both yours and senku’s signature.
hastily scribbled, but definitely yours.
———————
“everyone! shots on me tonight!” shouts an obnoxiously inebriated ryusui on top of bar francois’ counter. cheers erupt across the ship with some whooping and whistles.
“aren’t shots on him every night?” senku mumbles into your ear. bumping his shoulder into yours.
feigning nonchalance at the proximity, you reply, “i don’t know,” a queasy feeling twists in your stomach, “but i don’t think i can drink anymore.”
with his usual cocky smirk, senku snarks, “yeah, you definitely can’t.”
“its just,” a hiccup, “too damn loud.” you say while rubbing your temples.
senku stands and extends his hand, “you wanna go to my lab?”
you accept his offer and clasp his hand, letting him navigate you around the ship. feet dragging and eyes blurry as your mind slurs from the alcohol.
senku doesn’t typically allow anyone inside his lab, excluding dr. xeno, of course. everyone just assumes it’s nerdy science stuff and leaves him to his own accord. you can’t help but feel a little honored at the invitation.
senku carefully guides you through the dark oak door of his lab and shuts it behind him. the hand you held now somehow evolving into an arm. unconsciously, you lean into him for balance.
senku, who’s feeling a little bold, places his hand on your waist. he tugs you towards his desk. though it's messy with stacks of blue prints and notes, you’re charmed by his dedication to better the village.
still holding onto him, you take in the new scenery. it’s quite the spacious room despite it being below the deck of the ship. decorated (if you can even call it that) with test tubes, goggles, and little trinkets that he probably forced kiseki to craft.
in the corner is a queen sized bed, plush with the gray variant of yuzuriha’s Five Piece Ultra-Soft Down Alternative Comforter Set with Sheets™
“you can sit here,” pulling out an extra chair from under his desk.
before you can respond, he starts to ramble, “it’s quiet in here, right? i tested the oil we found from that reservoir we found recently, right? guess what? it was crude oil! or as you may know it, petroleum. well, i processed that into styrene and then used pentane as a blowing agent. boom! stone world styrofoam! i installed that into the walls of this room as makeshift sound proofing!”
processing none of that, you slump into the chair, replying with a, “dude that’s badass.”
humming a sound of agreement, “right? made it cause i felt bad for ukyo during late night experiments.”
senku slides into the seat next to you. fiddling with your fingers, you feel a hand creeping up your shoulder. too drunk to say anything, you lean into him as approval. basking in the comforting silence, he plays with your hair; twisting it between his fingers.
senku breaks the silence and lifts his arm, “do you want water or anything? hydration is important when you’re intoxicated. it’ll help with your inevitable hangover tomorrow morning.”
guessing the moment was over, you sigh, “yeah get me some water please.”
immediately jumping up, senku grabs a medium sized beaker (a beaker!?) and fills it with the water vase nearby. he fumbles with a drawer and pulls out something you can’t quite make out. taking steps back to you, senku extends the beaker and a pill.
you grab both, popping the pill under your tongue and then washing it down with water.
he raises his eyebrow, “you’re not even gonna ask what its for?”
putting the beaker back down, “senku, you’re a man trying to revive the whole world. whatever it was, it couldn’t have been bad for me.” you say, running your hands through your hair.
he lets out a breathy chuckle, “well it was an electrolyte tablet. you trust me too damn much.”
“i’d trust anything you’d do.”
“anything?” his eyebrow quirks.
“yeah?
“you’d let me do anything?”
“i’d probably even let you run experiments on me.” you snort.
there’s hesitance before senku speaks, almost as if he were picking out the right words to say.
he leans over, placing his right arm on your seat and shifting his weight to it. the change in distance instigates panic within you.
fuck, you’re so down bad.
he slowly opens his mouth, “are you serious? would you let me experiment,” a pause, “on your body?” senku’s eyes lock with yours expectingly.
heat creeping up your neck, you avert your eyes. in any other situation you’d retort with something along the lines of ‘just kidding!”
but, maybe it's because of the alcohol in your system, or maybe it's the undeniable attraction you have for the man. you find it nearly impossible to reject his eagerness.
i mean look at that face.
that handsome, handsome face.
that jawline.
chiseled and aching to be seen.
that-
nope.
you can’t look anymore.
eyes now glued to your shoes, you sheepishly cough out an, “uhm, i guess.”
“wow,” senku grins, “i have to record this moment.”
senku turns around, back towards you and hunched over his desk. drunk, confused, and now embarrassed, you’re almost relieved he’s no longer looking at you.
unfortunately for you, the panic from his proximity hadn’t subsided and any attempts of thought diversion weren’t working.
senku turns, whipping out a piece of paper with some writing on it.
he thrusts the sheet in front of you, and again, placing his hand at the seat of your chair. he excitedly speaks, “you meant what you said, right? if you meant it just sign here, at the bottom. first and last name.”
the distance between you guys closed again, you squeak a panicked noise. your hand scrambles to the fountain pen on his table and quickly scribble a signature.
“okay! whatever! just, back up!”
it can’t be that bad right? maybe he’ll just make you test new medicine? like a human lab rat!
he steps back, an ill intended smirk appearing on his face before quickly disappearing. “well you seem to be doing better. wanna go back up?”
you stand up and take a step, almost tripping over your own feet. stabling yourself on senkus desk, you agree, “yeah, let’s do it!”
ryusui spots you and senku walking up the stairs. “where have you guys been?! you’re missing the main event!”
with a secure grasp on your arm, senku asks, “what’s the main event?”
“me! of course!” ryusui shouts boisterously, simultaneously snapping his fingers and summoning his trusted butler, francois. seemingly popping up out of nowhere, they offer a plate of assorted alcoholic beverages.
———————
with the rest of the night a blur, you end your recollection session.
when you woke up, you were already constricted and exposed.
“senku. i know i said i’d agree to the experiments, but i thought you were gonna, i don’t know?! test substances on me?”
retracting the consent form, he wags his fingers, “no loopholes. a contract’s a contract.”
“since when was it a contract?”
“what? sorry, didn’t hear you.” he quips while walking towards the nighttable on your left.
the corners of his lips twitching, senku bites back his smile. “like i said, i’m gonna run some experiments on you.”
still freaking out; you ask, “what kind of experiments require me to be like,” you try pointing to your current state, but forget that your hands are bound, “this!?”
“just go with it, will you?” senku looks up at you, “i didn’t strip you. if you were wondering.”
what? if he didn’t, then who did? clearly perplexed senku continues, “you came down here after the party and fell asleep on the floor. i tried taking you back to your room but apparently you sleep naked cuz,”
you gasp.
“you started taking your clothes off, grumbling about how it was too hot.“
“oh my god, i’m so sorry, i didn’t mean to-,” you pause, “dude that doesn’t answer why im tied up to your bed.”
realizing his experiments weren’t going to proceed if he didn’t explain himself, he lets out an awkward laugh, “uhm, yeah about that. i may have wanted to redeem my ‘do anything to you’ pass. and i might have been afraid you’d try to run.”
“of course i’d run!”
“see! just go along with it! it’ll be quick.”
giving up, you sigh, “what are you gonna do to me?“
“figure it out. you’re a smart girl. i saw you looking at the equipment.”
oh yeah. the condom.
“senku are you trying to fuck me?”
though bold before, senku turns, clearly embarrased. he denies, “no! i just wanted to.. test some hypotheses. you know, about like, human reactions to different stimuli. specifically, like, sexual stimuli?
yeah he wanted to fuck you.
scientifically fuck you.
“you’re lying out of your ass right now.”
“whatever, yeah i am. look, i read a book about intercourse before petrification and i wanted to try it.”
“why didn’t you ask?”
“i did, you said you’d let me experiment anything,” he pouts.
this idiot.
telling someone you like them is difficult.
though, if anytime’s an ideal time for a confession, it…
definitely wasn’t now.
definitely not when you’re chained up to a bed with a mattress filled with straw. and definitely not when you’re butt naked and eagle spread.
nevertheless, you build up the courage. “if you asked, i don’t think i would’ve said no. i’ve literally had a thing for you since you revived me.”
“i know. you weren’t very good at hiding it. like when i dated luna. which was for political reasons by the way,” he adds on, as courtesy of your eyeroll.
“you know what, you also didn’t seem very happy when you found out i was in that other political marriage with ruri. oh and remember when-,”
“okay i get it,” you cut him off, face hot from embarrassment. guess you weren’t as subtle as you thought.
he places his hand above your left shoulder and hovers over you, “so, may we continue?”
adverting your eyes again; you should say no. you really should. but the idea of senku’s slender hands on you, exploring, feeling, touching.
just the thought sent heat to your core.
“yeah.” you nod shyly.
from his position, he lowers his face in front of yours. crimson eyes holding you hostage before they lid. he kisses you, gently. lips barely even moving together.
slightly pulling away, he stares at you. gazing longingly, like you meant something. pink flushing his ears, he leans back in. this time deeper. his tongue drags across your bottom lip before slyly sliding into your mouth.
mouths now moving in sync, senku climbs over you. his legs straddling both sides of your body.
biting and sucking your lower lip, whimpering every time he bites a little too hard. his hands run down the side of your frame and rest at your ribs, right under your chest.
you inhale sharply when he moves his hand up and lightly squeezes your breast. he rubs your nipple in circles before giving a little pinch. your chest leans into the contact.
he breaks the kiss to lick and suck at your neck, leaving marks scattered as evidence. slowly moving down, making progress down your collarbone and then to your sternum.
he pauses before reaching your breasts. eyeing your reaction, he locks his lips onto your hardened nipple. senku swirls his tongue in circles around the areolar, occasionally nibbling and sucking at the raised peak.
“mmph!” your hands thrash at your restraints.
he lets out an airy chuckle, “see? i knew you’d try to run.” you twitch at his breath chilling the spot it was once on.
he latches onto the other side, like he was making sure it wasn’t neglected. senku smiles against your chest, seemingly enjoying your attempts to break free.
you yelp when he bites down harder than before.
“what? you didn’t like that?” he cheekily looks up.
the feeling of his lips still lingering, you cry out, “no! just didn’t expect it.”
“no, its okay. we can stop,” he lifts himself off of you and hops off the bed.
“what?! why?”
clearly enjoying your desperation, senku wipes the shit eating grin off his face before turning back around.
he grabs the clipboard and the pen off the table and writes out loud, “experiment one. oral breast stimulation. subject response level,” he hums, “mm, a two? what do you think?”
exasperated and flustered, you whine, “i don’t know!”
pretending to immerse himself in his clipboard, he disapprovingly hums and shakes his head, “that’s not gonna work. i need accurate data. we can’t continue if you don’t cooperate.”
“i’m not doing this.”
senku sets the clipboard down and works to undo your restraints, “okay, i guess we’re done then.”
fuck. guess your pride can wait. “no wait! l-like a three?” eyes flicking to everything but him.
cocky, he jots, “a three. okay, noted.” setting the clipboard back down, he crawls back onto the bed and softly caresses your face. his hand moves to your shoulder, then to your stomach before lowering to your throbbing core.
insides bubbling from anticipation, you bite your bottom lip. palm on your abdomen, senku places a thumb on one of your lips and pulls it to the side. unveiling your inner folds, he tenderly blows on your glistening clit.
squeezing your eyes shut, a sharp exhale escapes.
“experiment two.” senku mumbles from below you.
a warm, wet sensation envelops your clit. you gasp, holding back moans as he laps without warning.
his tongue starts off slow, applying deep pressure to the hood of your nerves. wrestling around it in circles before unforgivingly flattening his tongue and pressuring upwards.
“fuck!” a wave of pleasure ripples through your body.
he hums against your lips, happily eating away like a starved man. thinking that his hands needed to pick up slack, senku inches two lengthy fingers into you.
caught off guard with the sudden intrusion you let out a high pitched cry and clamp your legs shut around him.
releasing his hold on your clit he warns, “keep them open, unless you want me to tie your legs down too.”
you hesitantly pull your legs apart.
“b-be nice then.”
“no promises.” he teases.
thrusting his fingers slow and deep, you feel your whole body freezing up trying to adjust to the new sensations.
still eating away, you are left in a frenzied state when thrusts faster and adds a digit without warning. your breathing staggers when you feel an orgasm build up.
“w-wait,” you stutter, “i’m about to-” he laps faster and curls his fingers inside you.
heeding his warning, you try clasping your legs together again. senku stops the attempt and immediately slams them back down.
”please!! wait!!” your muscles twitch. a blinding white pleasure takes over your body. chills wash over your skin as you let out a choke out sob.
licking his lips, senku releases his hold on you. he backs off smugly.
“i’d say that was around a seven. what do you think?” he reaches for the clipboard but you kick his arm.
“shut up.”
“hey, i need to record the data.” despite his tone, the smug smirk remained. senku stands and notes down the ‘data’. you notice his erection peeking through the lab coat.
“is that an erlenmeyer flask in your pocket, or are you excited to see me?”
eyes focused on writing, he states, “shut up. can’t help it. i’ve been wanting you forever.”
your face heats up at his confession, stomach doing backflips. you peek over at him. from behind the clipboard, a light red floods his cheeks.
“let me help you.” his hand freezes.
“how?”
gingerly, your jaw slacks open as you offer your mouth.
“shit.” senku drops the clipboard. he rips his lab coat off while basically leaping back onto the bed, stepping out of his tunic on the way.
fumbling with the rope, he quickly frees you.
you sit up so his crotch parallels your face. you gulp at the erection in front.
he nervously asks, “are you sure? once we start i don’t think i can stop.”
“take your fucking underwear off.”
he laughs under his breath and unveils himself.
thick. veiny. it’s pale with his mushroom tip angrily flushed. about seven inches? fuck. no, eight. how was he hiding all that under with that tacky e=mc2 tunic?
he slaps himself against your face and pushes his tip against your lips. “open.”
dropping your jaw he slowly pushes in. senku visibly shudders. he wraps his hand around the back of your head, fingers intertwining with your hair. you hollow your cheeks and swirl your tongue around his tip.
“fuck!” senku bucks his hips causing you to gag on the length. you bob your head rhythmically before he uses his grip on your head to push your mouth deeper onto him.
fully face fucking you now, he thrusts down your throat and forces your face to meet halfway. gag and saliva dripping down your jaw, you struggle with breaths in between his relentless thrusts.
you look up, eyes glossy with tears. senku groans above you. all of a sudden pulling out. you desperately gasp for air.
“don’t look at me like that. i just about embarrassed myself.” he shuffles to grab the condoms, ripping them open with haste.
you watch intently, dripping with anticipation. his length slapping against his toned stomach as he rolls the latex over it. he backs up, giving your clit a kiss before straightening his posture. he rubs his manhood along your folds, slathering it with your slick.
lining himself against your hole, he pushes. the rim of your entrance burns with the stretch.
strained, he coos, “baby, relax. i don’t wanna hurt you.”
you take deep breaths, trying to relax your walls. you feel every inch and every vein as he intrudes. once fully settled inside, you are left a twitching mess.
senku grabs the back of your knees, drawing your legs to your sides into a mating press. the new position allows senku to lean in close. still deep inside, he gingerly pecks the apples of your cheeks. licking the tears away he waits until you’ve adjusted.
lips locked again, senku passionately explores the caverns of your mouth. unconsciously, you start rolling your hips, causing senku’s breathing to stagger.
“seems like you’re ready.”
walls surrounding him, he starts pulsing in and out. your moans are muffled into his mouth. maintaining his rhythm, he pulls back from the kiss to stare at you, as if he were trying to engrave the memory into his mind.
legs wide. tear soaked cheeks. skin covered in rosy petal shaped hickies. angelic voice gracing him with a taste of heaven.
senku hits a particular spot within you that causes a long, choked wail.
“keep making those noises.” evidently affected by your state, he grows inside you. thicker. longer.
he moves his hands to the small of your back, forcing you to arch deeper into him. senku earnestly fucks that spongy spot inside you. he wasn’t just rutting into you. it was calculated. precise and intentional. your mind blanks as you reach your peak once again. noticing the signs, senku rubs circles into your overstimulated bundle of nerves.
cold washes over you. you let out soul wrecking moans.
your gummy walls shudder and twitch around him. “don’t squeeze me like that,” he strangles, “fuck, i’m close.”
his thrusts get irregular. faster. deeper. riding out your high, as he approaches his own. his grip around you tightens, accidentally digging crescents into your hips. panting as he pounds your abused cervix, he feels you go limp. sobbing while feeling more and more wrecked with every snap of his hip.
he gives one final thrust before finishing deep within you.
chest heaving, senku collapses above you; his face buried in your neck.
his lips curl against your skin, “i’d say that was like a 10.”
you groan.
“you don’t think so? well, every good experiment has trials.”
you feel a bulge grow on your stomach.
“GAH!!,” you shriek. “get away from me!”
a/n: this is my first fic! i spent like four days obsessing over it and might make it a hobby lol
