Since you say ANY drst character...

May i ask for my usual—Senku—and my unsual—Tsukasa—for today's meal 🤤?

Probably a few letters from the NSFW alphabet:

B = Body part (Their favourite body part of theirs and also their partner’s)

C = Cum (Anything to do with cum basically… I’m a disgusting person)

J = Jack Off (Masturbation headcanon)

T = Toy (Do they own toys? Do they use them? On a partner or themselves?)

THAT'S ALL HOPE THIS IS NOT TOO MUCH 🫣

—🪷

Senku:

B: Hmmm, a little hard to explain, but just think about it…I like to think his favorite body part for his partner would be the hips! Whether he's coming from behind you and snaking his arms around, tired from the work he's done, or latching his hands onto you as you ride his cock! He loves the way he can dig his fingers into the skin, watching it pool around his fingers, and if he pushes a little harder, he can feel your hip bone. It's odd but comforting.

His favorite body part would be his head! (not that head, hehehe). He likes it when your fingers pass through his hair. Relishing the way they softly massage his scalp. It's soothing, but when you're squeezing around his cock, yanking on his hair, it hurts in a way that he wishes you'd do it again, and again.

C: This is going to go hand in hand with J, but I like to think when he cums it's messy. It's not thick, not pungent-smelling, but milky white. Get some on your tongue, and it's bitter and a little salty. But when he cums, he cums a lot. You'd think you were milking him from how much he shoots from his cock from a single load.

J: I like to think he masturbates idly, not because he's aroused or for pleasure. He masturbates out of boredom, a sort of fidget. He'd be at his desk, pumping his cock as he reads articles. He could probably buy a fidget, but it doesn't provide the same stimulation as rubbing one out. But he only masturbates for the stimulation; rarely ever does he finish. So he's actually pent up on cumming, from how often he edges himself.

T: I don't think he owns any toys for his own pleasure, but he definitely has his own inventions in a box kept under his bed for his partner. A vibrator that he can control for intensity and speed, dildos of various sizes (for you and him), a sex machine that thrusts your own dildos which he can also control the depth and pace! Take a peek into his blueprints, and you might find something about a shock collar…

Tsukasa:

B: His favorite body part on you would be your thighs! He loves them as his own personal pillows, where he can rest his head, burrowing his face into them and inhaling the scent of your skin while losing himself in your warmth.

Goes crazy when he's lapping at your cunt and feels you tightening around his head. Squeezing your thighs involuntarily as the pleasure of his tongue becomes too much for you. He wants you crushing him with your thighs, keep him trapped between them, push him further into your pussy.

C: THICK CUM! The smell is pungent in a good way! When he cums, you can smell him in the beads of cum that land on your face. The taste is bitter, but not much more! He keeps a good diet, so the taste isn't all that bad! He doesn't cum an excessive amount, but the thickness of it makes up for it!

J: He masturbates a decent and healthy amount! Before petrification, when he was still in the ring, after every match, he'd be in the locker room, releasing the last of the adrenaline running through his body. During petrification, he's got pent-up tension, stress, and anger that needs to be released somehow!

T: If he's your partner, you don't need any toys. He's enough to handle as is! If anything, when he's pussy drunk or high on the need to fuck your brains out, you become his toy for the night! Let yourself become limp in his arms; let him just use you as nothing more than something for him to store his cum.

Was lowkey wondering what you think Xeno, Stanley, and Senku's fav positions were and if you could make like a little scenario from it (⁠~⁠￣⁠³⁠￣⁠)⁠~. IMO, I think Xeno would like missionary and riding, Stanley would like riding or doggy, and for Senkuuuu mmmmm not really sure. Thoughts?

Hmmm, fav sex positions…

I had to do some research, and I tried my best writing the scenarios, but it felt like writing a report, ngl. There's only so many ways you can describe getting dicked down, sentences away from the last description without sounding repetitive…

Anyways hope you likey! You might have to Google a few of these…

Warnings: Mentions of rough sex, soft sex, spitting, spanking, choking, breeding, baby trap...

Stanley:

Stanley loves the full nelson! Whether it's the traditional full nelson or standing, he absolutely loves the control it gives him. It's a position that allows him not only to be in control but also to dominate you! You have nowhere to run when you're trapped in his arms!

Stanley will have you locked in a full Nelson with his arms wrapped under your knees, forcing your thighs to your chest and your ankles right by your head. With your thighs spread apart, wet pussy exposed for all to see, his cock hammers into you. Thrusting his hips up and down, forcing the tip of his cock to kiss the entrance to your womb, teasing it with his seed.

With every feverish thrust, his balls clap against your ass, and with just a push of his hand, he tilts your head down so you can watch as your needy cunt swallows his cock eagerly.

He loves it when you become cock drunk in this position, and it's obvious when you become a toy in his arms. Your body slumps into his arms, your head rolls back, and you begin your mindless cooing as he teases you.

Another of Stanley's favorites is the Pinball Wizard. It's another position in which he can dominate and maintain his control over you, but it also gives him the advantage of seeing your lewd face.

His fingers dig into the sides of your thighs, teetering on the edges of your ass, as he maneuvers your body like a toy. He holds your lower body up with his strength alone, pulling your dripping cunt closer as his hips thrust his cock into you, staring into your eyes with a smug look, seeing you unravel by his hand. With your puffy clit staring back at him, he switches to holding you up with one arm, while the other rubs at your clit, teasing you cruelly when you squirt against his hand.

Honorable mention: Doggy Style and Reverse cowgirl. What man wouldn't want to see his partner bounce on their cock! Also, a perfect position for some spanking!

Xeno:

Xeno loves the classic Cowgirl, but not to be confused with reverse Cowgirl! He loves the vulnerability this position offers, as well as its duality of control! I think Xeno can be a bit of a switch! Some days, after another boring day at NASA, he just wants to lie and let his darlin just bounce on his cock, with little work needed from him. To have you in his arms, his mouth on your breasts, while you use him for your pleasure.

And other days, when work comes home with him, and he's absolutely riled with pent-up tension, he can take it out on you. He'll bounce you up and down on his cock, his fingers dig and claw at your ass while he ridicules and mocks you in your ear. Easy access to discipline you with his hands smacking against your ass, and even tease your tits with his teeth, tugging at your nipple.

Xeno loves to have duality in his positions, and the spooning position is a great example of that! He can crudely lock your face with his arm around your neck, pulling your arm behind your back, while he frantically thrusts into you from behind, or he can also gently kiss the crevice between your neck and shoulder while kneading your tits, while he lovingly thrusts from behind. Soft, loving, and nurturing, or mean, rough, and cruel, it doesn't matter because he'll end up cumming inside of your tight pussy either way.

Honorable Mention: Mating press with a version of Xeno that wants to baby trap you *Cough* Pathetic Old Man Xeno *cough*

Senku:

If you're having sex with Senku, you're likely in a Lotus position with him. It's an intimate position, with you sitting on his lap and your chest pressing against his. It's a messy position, with your limbs tangled together. Not to mention your forehead resting against Senku's as you gaze softly into his eyes. He loves seeing you lose all sense of reason as you become one with him.

Senku holds you in his arms, kissing you messily while you shake your hips against his cock. He holds onto your ass desperately, rocking you up and down, while he looks up at you in total adoration. It's intimate, but it also puts him in a position that exposes how weak he is around you. He holds you in his lap, putting you higher than him so he can admire you.

Another rather intimate position, Missionary! Sex with Senku is often soft and loving. Slow, deep thrusts that end with his cum spilling onto your stomach. But the few times it isn't, such as jealous sex or angry make-up sex, it's a rather easy position to communicate that. The tempo of his thrusts becomes fast, sloppy, and erratic. His hands that often hold yours are now trapped on either side of you, with a look that reveals his frustration. He can still feel your chest against his while spitting into your mouth or even choking you with his hand around your throat.

Honorable Mention: Elephant! An amazing position for lazy sex! But also for some rough sex!

Also, something that should be included for all three of them, but not really a position…SHIBARI!!! I feel compelled to write shibari with Senku or Xeno…

GAHHH WRITING POSITIONS IS SO HARD!

[spoiledfluids]

What are your thoughts on giving some of the dcst charas head? You can pick the characters I don't have a preference

A/n: I did Senku and Ryusui! Hope you like it!

Warnings: Oral male-receiving, slight oral fem-receiving, cum swallowing, choking, and gagging on dick, praise-kink, slight smell-kink.

Senku: When it comes to sex, I think Senku is a low-maintenance type of guy. He prefers something that isn't draining and doesn't overly exhaust his body. That being said, receiving oral is his favorite.

Senku loves being able to sit back and watch you lap him up. He often sits back with his arms behind his head, and you nestle between his legs. He can't decide which is better. Closing his eyes and just allowing himself to submerge himself in the feeling of your wet lips sucking and slobbering on his cock, with your occasional teasing licks and kisses to the tip.

Or sitting back and watching with half-lidded eyes the way you work to please him. Watching the way you bob your head up and down the length of his cock with drool and slober running down your mouth and his cock—balls slicked with your spit. Lost in the way you stare at him, lips tugging with a mischievous smile before you take him to the back of your throat. Loves the way you bat your teary eyes at him.

When you give Senku head, he tries his best to stay quiet. Soft, pitiful moans, gasps, and fragmented thoughts spill from his lips. He bites down on his lips to be able to stay quiet, often piercing the skin, and the taste of iron floods his mouth.

He tries to stay silent, but his body speaks for him. His hips stagger, flinch, and jolt uncontrollably. He bucks his cock upwards, catching you by surprise. He tries to stay still by digging the heel of his foot into the mattress, but your mouth is too much. More often than not, he loses control of his hands. They snap toward your head before he realizes what he's doing, and he pushes you further down his cock before releasing his load down your throat.

He prefers cumming in your mouth. If he can help it—if he has the restraint to not cum down your throat—he prefers to fist his cock over you, splattering his cum over your face. Like an animal marking what his, he marks you with his cum.

Ryusui: This man prefers to give oral rather than receive it. But if you're offering…he's not going to deny you. Just be prepared for him to return the offer. And what's the easiest way to return the offer? 69!!!

He's got your legs spread in front of him, thighs crushing his face, but he doesn't mind. Not when he's got such a perfect view of your puffy, needy pussy. And you? You're face-to-face with his hard cock. Standing upright in all its glory. Long, girthy, veiny, and a happy trail that leads to the base of his cock where his heavy balls sit. He's trimmed neatly between his legs, but the smell of him is intoxicating.

All of your senses are overwhelmed by the meal in front of you. It takes two hands to hold his cock, your finger tips barely wrapping around his cock entirely. You inch closer to it, resting your face between his legs, mouth sucking on the shaft. You kiss it feverishly, the taste of it addicting. You're teasing him just by sucking and kissing him, not yet having taken him into your mouth completely. He snaps his hips, bumping his cock to your face, and with his finger prodding your slick entrance, he urges—begs you to give him what he wants.

He gives you never-ending praise when you start to take him into your mouth. It's a struggle that deserves praise. He's so big and thick, your mouth aches from the stretch. You can't even fit him entirely in your mouth, having to use your hands to jerk whatever you can't take!

Ryusui doesn't shy away from being vocal. His moans are deep and breathy. Often cursing under his breath at how good you take him. As mentioned previously, he praises you up and down! Starts to greedily lap at your wet pussy, not wanting to be outdone by his favorite girl!

When it comes to cumming, he prefers finishing inside your mouth. Letting his cum burst onto your tongue, fill you from the inside. He wants you to swallow every bit he gives you. Scolds you when he sees even a speck spill from your lips!

FERAL | III. Old Dog, New Tricks | Previous Chapter |

Series Summary: On the outskirts of Ishigami Village, caged and chained—poked and prodded—lies Senku’s darkest secret and most cherished experiment—you.

TW FOR SERIES: Stockholm syndrome, dubious consent, sexual experimentation, unethical experimentation, female masturbation, vaginal fingering, humiliation, verbal humiliation, sexual overstimulation, blood and injury, feral behavior, reader is held in captivity and held under observation, reader was not raised around other humans and lacks social skills.

Whoever said you can't teach an old dog new tricks didn't have the same lack of parameters as Senku. Senku understands that before the world turned to stone, some things couldn't be controlled, and that every experimental proposal ultimately comes back to the question that stunts any real progress—"Is it ethical?"

But in a world that remains in the Stone Age, where Senku is momentarily the only scientist, who could argue against him? What ethics committee is there to stop him? And stop him from what, and to whom?

You had no name. No ties to the Ishigami village. If you did, surely Senku would have known of a girl living in the woods. Even when he hinted at it among the villagers, if anyone had been banished, no one matched your description. Who is there to save you when nobody knows you exist?

You are no one.

When it comes to teaching an old dog like you any tricks, Senku observed that negative reinforcement was most effective. With a kick to your abdomen or a hit to the head, you quickly learned what he asked of you.

At first, it took you a couple of days to fully understand what he wanted. You took countless merciless hits, often leaving you writhing on the ground, too weak to get up. Scrapes, cuts, and bruises are scattered across your body as you whimper. Blood dripping onto the rock below you, staining the ground a deep crimson that remains even after it's been cleaned. Only when your eyes stare weakly at his and your breath is shallow does he know you are done for the day. He'd clean you up, wiping the blood from your face while you refuse to look at him.

Eventually, you learned, and Senku no longer needed to beat you near death for you to learn.

Senku walked into your captivity with a smile on his face, as if he hadn't beaten you the day before. He finds you curled up under the fur blankets, trying to hide beneath them. Pulling the end of the blanket, he unveils your frail body to him. You look at him in the eye with fear and animosity, something that means nothing to him.

"Stand." It's slow and staggering. You shake and tremble as you push yourself up, chains clattering and dragging around you as you rise to your feet.

"Sit."

The chains rattle again as you try to steady yourself. You rest on your knees, hands in your lap, meeting his gaze, and Senku smiles back at you like a madman. Looks like he didn't have to hit you to make you listen. But he wasn't going to congratulate you for following instructions.

"Belly up."

You don't move, but an expression of impending doom flashes across your face. Your eyes begin to water before Senku speaks or even moves. Your pupils dilate, and you quickly look away from his gaze. You whine and whimper, already pushing your feet against the ground, attempting to put distance between you and him. You try to crawl away, but your chains drag behind you, and Senku steps on them, making moving any more futile.

"No, no, no, no," your cries break, turning into sobs in seconds. Senku steps closer to you, and you begin to tremble violently. You're holding your head in your hands, shaking furiously as Senku shows you barely any pity.

Just as Senku raises his hand over his head, ready to hit you with the rock in his hand, you slip. You knock yourself onto your back, hands covering your eyes as you continue your pitiful chanting of 'no'. Fortunately for you, and much to his dismay, you manage to position yourself 'belly up'.

"Belly up," Senku repeats, reinforcing the command.

"Bell-e up," you repeat back to him.

He's not supposed to reward you for a job well done, not when it's expected from you, but he can't help himself. Crouching down to you, he presses his palm against your exposed stomach. Your skin is hot to the touch, instantly flushing him with heat, a sensation that is both literal and figurative. His pale skin against all the bruises he's left on you contrasts beautifully. He admires them, caressing and lining the shapes with his finger.

After he's admired every work he's left on you, he rubs his palm against your belly. Dragging his hand up and down, soothing your skin. His fingers dig in just enough that your skin drags with him. He notices the effect his tender touch has on you. The way you bite your lip or when your thighs clench and rub together. The sight of it is tempting. How would you respond if he were to go lower and lower? Would you act like before? Will you tell him to "moov"?

"Open." It's not a command just yet, but a new trick he wants you to understand. He holds your thighs in his hand and repeats again, "Open."

It's a demonstration of what he wants you to know, including what to do and when he'll inevitably quiz you on the command. Your legs spread apart, your underwear loose around your waist, does a poor job of hiding your cunt from his eye. He pats your cunt as if he were patting a dog.

"Good girl."

You feel things that aren't physically there. A type of pain you can't find the source of. A pain that doesn't make you cry out but leaves a heat that washes over your body. A flush that overwhelms you. It makes you want to run and hide. You feel the need to drown yourself in water—the urge to scrub away the imaginary dirt that litters your skin.

You do things without really understanding why.

Senku wasn't around, having left hours earlier, and he wasn't going to return until the following day. It's a routine you find yourself adjusting to. When he's gone, you continue to follow his commands.

"Stuh-and." Your voice tries to mimic Senku's words, often only replicating a primitive, broken pronunciation. And as if he were here, you rise to your feet.

"Sit."

…

"Bell-e up."

…

"Oh-pin."

"Gooood girl." The words slip from your lips with a wobbly smile, and your hands hide your bashful eyes. As if hiding the pain that flushes across your face from any lurking eyes. The pain starts small, often burning across your face and moves slowly across your body, settling between your legs.

"Gooood girl," you repeat again, this time patting at your cunt, just as Senku had once done.

You do things without really understanding why.

You lie prone on your fur covers, wrapping your arms and legs around them, forming a mold of sorts. You bit down on the covers as you rock your hips against it. The pace of your staggering hips is slow and sloppy, but it helps with the throbbing between your legs. Your underwear is hooked lazily around your ankle, and the slick from your pussy wets the fur, making it easier to rut against.

"Sehkuu," you moan into the furs, eyes brimming with tears as you rock yourself for comfort. Hips moving back and forth, aching clit rubbing against the matted fur, you continue to embrace your covers as you call out for Senku.

You rut and rut against your covers until that uncomfortable tightness settles in your belly. You feel your cunt pulse, thighs and toes trembling and numbing as your hips shake. You feel something wants to come out, burst out of you, and you can't hold it back anymore. Your back arches up, straddling the covers beneath you as you begin to bounce. The chains rattle with every recoil, silencing the wet, sloshy sounds of your hands creeping down to your pulsing clit. Your inexperienced fingers rub without regard. No set repetitive motion—just anything to relieve the pain.

You rub and bounce, your voice raw and shy as your own sounds echo back to you. And then everything comes crashing down. The tightness in your belly snaps, and a sound you've never made crawls up your throat, ringing and teasing back to your ears. It spills from between your legs, wetting everything beneath you as you shake uncontrollably.

You don't know why the pain settles between your legs and why it won't go away until you rock yourself against your covers. But you do know it isn't something you can show Senku. It would only amplify the innate urge to hide yourself if he were ever to inspect between your thighs. To have him so close to something so… You're sure it's something he knows about.

…

"Good girl." Collapsing against your own mess, you fail to notice the lingering shadow at the entrance, which saw everything.

[spoiledfluids]

senkus number one fan here!!

what a cutiepie he’d be as a sub, all his friends think he’s either a mean top or just abstinent. but he’s going brainless in my bed from how much im peggin’ him awwwww awww cant even do science anymore awwww

Warning: Pegging, cock-drunk, orgasm, cum..

A/n: Search up 'Amazonian press sex position,' please and thank you!

From concepts to ideas, ideas to thoughts, and thoughts to words, Senku has always been able to express whatever comes to mind. He can express his ideas while weaving in and out around the lab's resin countertops, synthesizing complexes and refluxing solutions simultaneously, without a stutter. But now, legs shaky and numb in the air, held up by your grip, pressing his thighs to his chest, Senku can't even utter a word, let alone formulate a thought.

"Augh…ughh…hnghh," words—if they can ever be considered words by the Oxford English Dictionary—slip from his trembling lips, past the drool pooling on the sheets beneath him.

His hands clutch feverishly at the cum-stained sheets—squeezing them between his fingers with every toe-curling thrust that presses the bulging veins of your toy against the gland of his tight walls. A feeble body weak as his, under your mercy as you continue to thrust your dildo inside of him, watching the skin under his stomach bulge from the size of your toy alone.

A greedy gaping hole that squeezes tightly around your dildo, eagerly accepting it as his hard cock twitches and shakes with every hard thrust. His cock, small in comparison to the one inside of him, spills beads of cum along his stomach, falling around the mound that forms underneath it.

You have him in a position where, if you could, you would physically impregnate him. Forcing the dildo in the depths of his ass, repeatedly pressing and stimulating his gland, causing his feet to shoot upright, shaking and trembling as he continues to mumble unintelligible words. Your ass hits the underside of his, skin smacking against his balls as you continue to leave him delirious.

His own cum shoots upward, spraying messily across his brainless face. No thoughts behind his eyes. No comprehensible words other than his own disoriented muttering. Only a cock inside of him would leave a degenerate version of himself.

A/n: Something short! 1st time writing pegging!

Sorry if it's a little redundant at the end, I was watching Better Call Saul, as I wrote this!

Slowly clearing out my inbox! Two more to go! YAY!

Like Him—Sneak Peak

Summary: Byakuya's death exposes feelings that were buried to keep up family appearances, but now that he's gone, nobody is holding them accountable for right and wrong. A daughter who only seeks the comfort of her father's touch once more, and a son who struggles to keep the promise he made to his father and to bury the feelings that keep resurfacing.

WARNINGS: PSEUDOCEST/FAUXCEST/STEPCEST! This fic is going to explore more psychological themes! Father/daddy issues, unhealthy coping, unhealthy codependence...

READ AT YOUR OWN DISCRETION!

You haven't told Senku about the images that materialize before you. They come and go faster than you can process them, leaving you silent and still as you search for meaning in their appearance. They emerge from the shadows of the village, the grains of sand, the waves of the ocean, the positions of the stars, and even the moon's craters. The images themselves appear hazy, contorting into shapes that your mind remembers—a face you desperately want back.

There's no logic to their appearance. They appear whenever they want, with no regard for your feelings. The moment you catch a glimpse of his face, it always ends the same. Before you can move to chase after him, he disappears in the blink of an eye. Your face wilts into one that flickers between fear and sorrow. Fear of why he haunts you. Fear of why he appears to you as if he were no longer around.

You haven't told Senku, and you don't plan to. Not until you understand why your own father won't leave you alone.

Before images of your late father flashed in the inanimate, he appeared as fragments of recognition. Ishigami village—descendants of those on the spacecraft—unveils bits and pieces of Byakuya in their faces. You often find yourself staring at them with a soft look, yearning for your father. Unconsciously, you begin searching for him, gravitating towards anyone who even remotely resembles him.

His name was Jasper—the villager who most resembled Byakuya. White hair combed back messily along his shoulders and thick eyebrows. The two stark physical differences between them were the beard Jasper had, which you like to believe Byakuya's stubble would've looked the same if he ever committed to letting it grow, and the expression he carries. It's harsher, meaner, and more stern than the ones Byakuya ever put up.

A/n: Just a sneak peek for now! Can you feel the angst and the taboo? I plan on doing three chapters in total (subject to change!). 1st exploring the complicated relationship the reader has with Byakuya, 2nd the unhealthy codependence between the reader and Xeno (more in Xeno's POV), and third would be Senku's POV as he watches everything unravel!

I don't know when I'll upload again! I'm going to be a bit busy in the next few days! And I'm in a bit of a writing slump again! Maybe I've never left the slump in the first place?!?! I can yap about ideas with ease, but writing is SOOO HARD FOR NO REASON!

I just had a thought:

Senku getting cucked by Xeno fucking his S/O!

Just imagine Senkus pathetic expression when he realises, that his S/O actually enjoys it!

I know you see the vision >:3

🪻

Senku getting cucked—

GIVE IT TO MEEEEE!!!!

Senku getting cucked is just the natural order of things. GOSHHH WHAT IF I WROTE A CUCK SERIES FOR SENKU?!?!? His s/o just getting passed around just for the kingdom of science to succeed...

Senku getting cucked by Tsukasa...Hyoga...Moz...Xeno...Stanley YES YES YES!!! Should I???

Anyways! Senku gets cucked by Xeno and realizes he has a lot to learn about the science when it comes to the female body. He didn't know you could squirt, but clearly you can by the mess on Xeno's thighs. He hears whines and moans he didn't think your vocal cords could produce! Even when you're staring right at his eyes, you're so dumb on Xeno's cock, you can't help but just moan "Xeno, Xeno, Xeno" over and over.

...I know of a drabble of Senku getting cucked by Stanley if you're interested 👀

I LOVE CUCKING, I LOVE NTR!!!
