MOCHI MOCHI NO MI ; this fruit allows its user to create, control, and transform into mochi. the mochi created is generally thick, viscous, and stretchy - though its texture and hardness can be altered, to a degree. KOPI KOPI NO MI ; users of this fruit are able to copy other peoples' abilities through touch. (a/n: this fruit is non-canon from an op movie, but it fits perfectly in this fic, so... 😈)

y'all i literally did a size comparison with katakuri's height and like, a 5'6 reader (worldwide average for women is apparently 5'3 but at this differences, i doubt a few inches matter lmao) so keep in mind i tried using this for writing the fic hehehe
when katakuri first meets you, he can't stand the sight of you - now, whether that's because of your personality or the fact that his mother arranged for you to be his bride, that's up for debate - but it certainly isn't because of your looks.
barely half his size and with a sweet, placated grin - you're just as bad as the rest of them. he doesn't give a shit about how he finds you very attractive past that silver tongue of yours - marriage to him is simply a hindrance. nothing more than a political scheme set up between powerful families at the misery of their offspring. ceremonies, galas, parties... he's busy running over his island and the land's military as is, and he only hopes you don't put up a fuss when he ignores you.
at least you're keeping big mom busy, having brought her a cake with the finest ingredients from your lands (he rolls his eyes at that one) and complimenting her on everything you see in the room. she's taken a huge liking to you, which he supposes isn't the worst thing for him - but you're probably the dishonourable, say-what-people-want-to-hear kind of person, and that's what bothers him quite a bit.
until you prove him wrong.
turns out, you're quite honest and capable, and you make it clear you're not just there to sit around and look pretty. you take on some of his duties on komugi island. the townsfolk take a liking to you (though sometimes he thinks you're too soft on them) and you manage operations well.
you’re polite and curt to him whenever you finally see him in the evening - he’ll be seated beside you at dinner, but choose instead to make conversation about politics and the state of the island with his siblings while you do the same with whoever’s around you. you’re usually in bed by the time he arrives, sleeping on opposite sides as if a barrier exists between you.
at first, you’d tried to bond with him. when that didn’t work, you’d chided him about certain things - from anything domestic, to complaints from residents of the island - but with his mother being a warlord of the sea, you were still careful with your words. as much as you tested his limits and nudged, you never pushed, choosing to be strategic in what you asked of him. little did you know how much frustration was building up inside of you as a result.
disaster strikes the first time you accidentally interrupt his merienda. well, not-so-accidentally - the chefs had warned you not to go into the room, but you’d had enough of his cold demeanor toward you and had retorted with,
"what's he gonna do, kill me? i'm his fiancée!"
you enter to find him lounging on his back, eating a pile of freshly-baked doughnuts. you gently place your hand on his arm, and the look when his eyes crack open is downright murderous, a shiver darting down your spine and causing you to react on instinct.
with quick use of your devil fruit, you copy his powers and cushion yourself when he forcefully pushes you away on reflex, bouncing safely off the nearby wall.
his mouth hangs agape for a moment,
“i’m - i’m sorry, i would never -”
his eyes dart back and forth, until they settle on you, dark but somehow pleading. he’d never even dream of hitting you, regardless of his distaste for your attitude and the whole situation - but he’s positively enraged at your audacity to dishonour his simple request of leaving him be during this time. he wouldn’t even think of activating his observer’s haki, because no one before you even had the gall to approach his enclosure when told not to.
the rest of the room has cleared out in fear, but you stand up. your eyes are locked on his, determined. before he can utter a word, you huff,
"calm down, katakuri. the hell do you have to hide? that you like eating food? everyone on this damn island does!"
he blinks dumbly at that. you’re unphased. unbothered. as if him nearly maiming you mere seconds ago never happened, and you brush yourself off in such a casual manner. all he can say, pointing at his face, is,
“but - my mouth.”
your face goes deadpan - unimpressed, even, just absolutely exasperated at his attitude at this point,
"oh, what? i'm on an island of freakin' dancing shit and you think your mouth is something i'd be weirded out about? i mean, how would we kiss when we get married anyway? did you really expect me to just… kiss you over your scarf? y’know, i was gonna bring it up eventually, but this is just ridiculous, i mean…”
kiss. his mind had already been rushing at a million miles an hour, but no amount of observation haki could have predicted the words that spilled out of your mouth, each hitting him like a bullet - not of metal, but something soft, gooey, uncomfortable, and somehow reassuring. that is, until you continue,
“well, those teeth… they’re kinda doin’ something to me right now, if i’m honest.”
brash and honest he can deal with. but brash, honest, unhinged, and… really attractive (it sneaks through the impenetrable cracks of his mind, seeping out no matter how much he tries to stuff it back in) - that’s a whole new ballgame for him. so he moves away from the topic,
“your… your powers.”
“oh, the copy-copy fruit? pretty handy, huh? you can stretch your body with yours, right?”
you attempt the feat, successfully reaching your arm across the room. it snaps back in place as you turn to look at him, a cold stare freezing him.
“y’know, i’ve had enough of your grumpy, ‘i-hate-my-fiancée’ routine. you don’t have to worship the ground i walk on, but would it really kill you to like… be nice? do things that a husband should do with his future wife?”
this wasn’t in his calculations. feeling vulnerable from having his biggest secret exposed to you, yet your reaction confounding him, he’s in no position to stonewall or reprimand you like he’d been able to do before.
“what… sort of things?”
he doesn’t know why that had come out, but he has a dreadful, knowing feeling as to why your mouth curls into something wicked upon him asking.
“well, i’ve been thinking ever since i saw your powers, and now finally using them myself…” you’re right beside him now, trailing a finger up and down his leg, “... have you ever thought of making love, katakuri?”
a silly question. of course he has, especially looking at you - though it was a topic he’d put off through all this talk of marriage. those thoughts had long left his mind - it was impossible with your size, and he’d assumed insemination through scientific means, or a surrogate or even a bastard child with a giant. of course his mother expected offspring - thinking about it now, had she even considered your size difference?
but this. the thoughts rise to his head as the blood rushes out from it. he doesn’t need to use his haki to know what comes next.
“you could use me just like a toy,” you giggle, “and i bet i could take all of you. maybe that’s why you’re always so grumpy? nowhere to release it all?”
his breath releases shakily as you stretch your hands up to undo his belt. he doesn’t stop you as you tug on his zipper then waistband, freeing his juicy, veiny cock, comically almost the size of your body.
you pause to strip yourself, and he removes what’s left - gloves, boots, and all.
“put your hand on your thigh. palm up,” you command, and he obeys.
you use his mochi powers to climb up onto his leg, pulling his pinky finger toward the centre of his palm.
“ah, this should be a good warmup. i’m already wet, y’know?”
it’s strange, the way you position his digit under you and stretch yourself to fit around it. your insides are warm, soft, and plush. he finds himself groaning involuntarily at the feeling, cock twitching quite visibly.
he lets you move up and down at your own pace, but your powers ensure you feel no pain whatsoever - just a nice stretch, and the pleasant feeling of being stuffed full.
“katakuri, this feels amazing. you feel amazing.”
he shudders at the way you say his name, beginning to palm himself with his free hand.
“you know, i could probably fit my mouth around you too. but - ngh - i’m getting impatient.”
you move up a couple of sizes, to his middle finger. when he curls it, he hits your enlarged g-spot, earning another whine that goes straight to his dick. the fact that you’re so much smaller than him somehow makes this hotter than if he’d been married off to a giant or something.
“katakuri, i can take it. please, let me on your cock now.”
you don’t have to ask twice, slipping easily from his finger from all of your juices. he circles his fingers around your waist, carefully as not to break you.
“you don’t have to be so gentle, you know? i’m mochi now, silly!”
when did your giggling start to become endearing rather than annoying? he melts over how cute you sound.
once you’re aligned with him, he fully registers the difference. for a second, he thinks - no way this is real. no way she’s going to fit.
but with deep breaths and maneuvering on your part, you mould your entrance around him, sinking down slowly. admittedly, it’s more of a stretch than before, but still not veering into the range of being overly painful. the fact that you can make yourself tighter on him too? you’ll have him wrapped around your finger in no time.
if only you had a mirror to see yourself in - how strangely shaped you’d be! but your fiancé doesn’t seem to mind at all. his hand shakes as he prepares to move you up and down, watching the way you bulge around him.
he watches you for any signs of discomfort, but there’s only pleasure to be seen in your face, even as he grips you a little harder.
and he surprises you when he takes his thumb, searching in your folds until he finds your clit, rubbing it in circles and stretching it out so it can be fully stimulated.
“katakuri! fuck!”
you cry out, and he impales you deeper, mushroomed tip poking at the walls of your cervix and engulfing him delightfully. he starts to get rougher as you beg him to, and he doesn’t think he can last long with the absolute filth you’re spewing out of your mouth.
“mmh, i love being your little fucktoy. i’ll warm your cock anytime, or take you down my throat if you let me use your powers like this all the time.”
he twitches, this time inside you. you tighten yourself around him in response. it seems that with enlarging yourself comes more bodily fluids - you’re drenching him, and the slick sounds produced from him moving you around like a ragdoll are positively sinful. the friction of his hands is nothing compared to your inner walls that have him rolling his eyes back into his head.
though he’s not at all talkative during sex - as expected - he’s quite loud with his groans, which only spurs you on further. you’re babbling now,
“ooh, you can make me a dildo out of your mochi. so you can still fill me up even when i’m not using your powers. or maybe your tongue next time? it’s quite long. oh, and your teeth! i don’t mind if you scratch me with those.”
the image of you in evocative lingerie, sprawled out on your shared bed, waiting to be bred and barely making a dent in its vast expense as you welcome him back from a trip abroad, comes to his mind.
you reach your release before he does, the firm circles he’s been making on your clit with the pad of his thumb have you convulsing, limply and helplessly on him and giggling like a madwoman.
finally, he doesn’t address you as woman, or you, there - he calls out your name, a beautifully gruff, desire-laden version of it - as his own peak comes and he can’t hold back anymore.
his cum fills you at once, forcing his cock out from the sheer amount of it all. you can’t hold it all as you shrink back to your normal size, and it gushes out until you’re in the middle of a pile of it, remarking at how it actually smells like mochi and salt. some of his seed still seeps out of you, the lewd image threatening to turn him on again.
between his panting, his post-nut clarity hits, but not with the regret he’d once expected. he sees you laughing brightly, a blissed-out smile on your face, and imagines you with his child. with the same kindness you show to others, but with the discipline you have over his lands.
and from what he thought would become a loveless marriage, charlotte katakuri falls in love.
author's notes: ok wow yeah so pretty kinky ig lmao, not sure if this has been done before bc i don't really read a lot for katakuri. no, i didn't address reader's potential pregnancy bc there are hella weird couples in op so... if you and katakuri have a kid, it'll work out, mkay? a bit rushed but just happy to be writing longer form fics again aaaand reviving a kinktober thing i had intended to finish. enjoy!
