declarations (alternate version) — kaiju no. 8, hoshina soshiro x f!reader, use of foods as nicknames, childhood best friends dynamic, reader wears a dress and heels, oral (f!receiving), 3k words — the first bit is the same as the original but it does deviate

"Why do I need to wear a dress?"

Hoshina Soshiro glances up from where he's lounging on your bed. You've already pulled on the dress, of course, and he watches with probably way too much interest as you tug and adjust the way it drapes along your body. It's pretty. It fits perfectly, though you have no idea when Soshiro learned your measurements enough to show up at your door with such a gorgeous dress hanging from his fingers. Maybe he got them from Okonogi-chan?

"You'll be walking 'round with me and the Captain, egg tart, so you've gotta look the part," he says idly, though you can feel the burn of his stare along the newly exposed skin of your back. "And don't forget the heels!"

You glance at the cute, strappy heels he left by your mirror and frown. "If I wear those, I'll be taller than you, Soshiro-kun."

"Aw, that doesn't matter," Soshiro says. He sits up and you look away from the flex of his incredibly defined abdominal muscles beneath his compression shirt, which he apparently wears all the time, even under his formal dress uniform with all its tassels and buttons.

God. Embarrassing. You really need to get your staring issue under control.

"I can fight whoever looks at ya."

"Wha— ?" Heat sears across your face as you splutter and spin around to face him. The skirt of your dress twirls with the movement and you catch his gaze snapping down to your thighs. "Why would you need to fight anyone?"

"Hm?" You take a step back as he gets up and stalks over to you, holding your breath subconsciously as he kneels at your feet and takes one of the heels in hand. Your room suddenly feels warmer, the air hushed, as if the two of you are the only ones who exist in the entire universe. Soshiro chuckles quietly and shoots you a grin that makes your knees feel wobbly.

"Soshiro-kun?"

"Well, 'course I'm gonna fight for ya, apricot," Soshiro says. You flinch as he reaches out to grip your calf, the rough callouses on his fingers scraping lightly as he lifts your leg and slides your foot into the shoe. "You're my best friend, yeah?"

And I'm just a simple man in love goes unspoken as he carefully ties the silk around your ankle to keep the shoe in place. You wobble a bit at the balance and he glances up from beneath his violet bangs. "Hold onto my shoulders," he says quietly, reaching for your other leg. "Don't worry, I've got you."

"S-Soshiro-kun, I can put these on myself," you mumble, heat flaring up your spine at the careful pressure of his fingers on your ankle. He lifts your leg and you grab abruptly at his shoulders, fingers digging into the thick muscle there as you regain your footing with his support.

Soshiro lets out a breath. "I know," he says simply. "But I wanna do it."

Is this what men do when they're in love? You wouldn't know — the only man in your life you've ever cared about is right in front of you, and he's refused to elaborate on his strange statement no matter how many times you've asked. You have a feeling he means it, though.

Like, really means it. You love Soshiro — of course you do. You've always loved him. But lately it's felt… different.

Still comfortable. He's still your biggest supporter and vice versa, and he still knows exactly how to cheer you up and make you laugh. You know all his ticks and tells, and you take great pride in taking care of him while he's looking out for everyone else.

But at the same time… it's uncomfortable.

These little touches — they're new. The way his gaze lingers on your body is also new. Or… maybe you've just never noticed before. It's not a bad thing. But it makes you feel strange and fluttery inside and you catch yourself daydreaming about what it'd be like to actually get a hickey from Soshiro. Your best friend.

You stare down at the top of his head and try to repress a shiver as he skims up your legs to where your skirt rests against your thighs. His touch leaves behind a trail of warmth that burrows deep. "Um— ?"

"Ya look real pretty like this," he says. You're still holding onto his shoulders as he rises from his crouch, your entire body hot and hyperaware of how close he's standing once he straightens. "I could really just eat ya up." The smirk on his face makes your heart thump painfully in your chest, but he doesn't give you a chance to question it before he's grabbing your hands and spinning you around in a little twirl.

"S-Soshiro!"

You let out a little yelp as the room suddenly turns sideways, your center of gravity abruptly gone as Soshiro scoops you off your feet with one strong arm behind your back and the other beneath your knees. You throw your arms around his neck in a desperate move to keep from falling, though you know he'd never drop you.

Soshiro looks down at you with a glint in his eye. "Maybe I will."

"You'll… what?" you ask, breathless. He looks… hungry. Something about that look makes your stomach clench. "Soshiro-kun?"

"As your best friend, I think I've gotta do a lil inspection," Soshiro says brightly. He carries you over to your bed effortlessly, laying you down with a care that makes you burn up in a mixture of embarrassment and want.

You want… something. Soshiro gently detangles your hands from behind his neck and brings them up above your shoulders, gripping both wrists in one of his hands. His other hand is planted by your shoulder to keep from squishing you, though he keeps his balance with a knee between your thighs. "What…?"

"Just checking," he murmurs, leaning down to brush his nose against yours. You can feel his breaths on your lips and you strain a little against his hold, wondering if he can feel your pulse beating rabbit-fast in your wrists. His hand is trembling, though you can't imagine it's from the strain of holding himself up. "Can I?"

What… what is he asking?

Does it matter? It's Soshiro —

"Yeah," you breathe. "Go ahead."

His lips brush yours in a whisper, an exhaled sigh, a pressure as light as a butterfly. You make a funny sound and he grins as he skips down to your neck, pressing a firmer kiss there at your pulse.

"You do taste good, chestnut," he mumbles, just before you feel the sharp nip of his canines pinching your skin. You yelp in surprise and he chuckles, brushing his lips across the spot in apology.

"What did I say about food nicknames," you manage to gasp out, blinking blearily as he rises back up to face you. The tops of his ears and the arch of his cheekbones are painted a charming pink, but his eyes are serious as he meets your gaze.

"Are you good?" Soshiro asks.

Are you? You do feel good — better than good. The way your heart is racing would probably raise some eyebrows in a medical ward and your brain feels like mush, but. You've had your share of meaningless crushes — puppy love, infatuation — but none of it ever really mattered because you've always had Soshiro.

None of it ever felt like this.

Oh.

"I'm good," you whisper.

"And this is okay?" he asks. "I'm not — I told ya I don't mess around when it comes to you."

"I'm not messing around either," you grin up at him, feeling suddenly buoyant as the pieces click into place. "I'm yours, Soshiro."

Your best friend looks at you for a moment, but whatever he sees in your expression makes him laugh — a rough burst of sound punched out of his chest — before he leans down to kiss you again.

You can feel him smiling into the kiss.

It's a little awkward — he bumps your nose and you can't keep from grinning, either, so the kiss turns into several kisses, the smooth press of his lips against yours sending heat curling through your veins as his kisses get deeper, hungrier. He tilts his head and finally lets go of your wrists to grasp your chin, moving you to get the angle just right, though his careful intentions go up in smoke when you reach up to tangle your fingers into his hair and tug.

He pulls back with a gasp, eyes wide and pupils blown, panting as if he's just finished fighting off a kaiju. His voice cracks as he murmurs your name.

"Yeah?" you lean up to brush your lips against his jaw, admiring the strain of his neck as he huffs. "You're so pretty, Soshiro-kun."

It takes a second, but Soshiro's next breath is a sharp inhale as he presses his body against yours, pinning you to the mattress.

Then he whines.

Oh, god.

The sound seems to startle both of you, but he recovers first, dipping down to kiss you senseless as the ache in your core intensifies. He's solid and warm and heavy on top of you, his hands burning along your arms and sides and skimming over the neckline of your dress before he seems to settle on gripping your hips as he bullies his way between your thighs. The gasp you let out is loud in the thick air of your room, but the groan he lets out when you squirm against the solid, unyielding length of him is even louder.

Soshiro moves back to pressing hard kisses to your neck and exposed shoulders, panting hard as you whimper with every stinging nip of his teeth. "You're gorgeous," he murmurs, "you're so fucking perfect, I can't —"

"S-Soshiro," you whine, wiggling your hips in an effort to chase the electric sparks of pleasure rising with every sharp, aborted thrust of his hips. "What's — why're you —"

"I'm tryin' not to cum in my pants," he grunts, fingers digging hard into your waist to still you. You sob at the loss of friction and Soshiro huffs. "Fuckin' hell — you're so — but I can't be walking 'round the party all dirty."

Your eyes snap open at the reminder and you shove at the shoulders you were clinging to for dear life a moment ago. "The party!"

"Yeah, the party," Soshiro laughs, grabbing one of your hands. He presses a kiss to the leaping pulse in your wrist. "Didja forget, pumpkin?"

The tender affection somehow makes you warm, even as his hips grind slowly against your core to make you burn. Your legs, which you hadn't even registered moving, drop to the sides, sending your dress to pool further up your thighs and exposing the thin fabric of your panties. Soshiro glances down at the movement, but you can only see the way his lashes flutter at the sight before he's grinding his clothed cock against you again.

A muscle in his sharp jaw ticks as he glances back up at you. "Ya look real good," he says, "and I'm tryin' to do this right, but —"

One thing about being best friends for your whole lives means you can tell when he's holding something back.

One thing about becoming lovers with your best friend is that now you can see he's been holding back from this.

"You can't go into the party like this," you point out. Soshiro laughs, a strangled sound.

"We're not havin' a quickie as our first time," he says firmly. His expression lights up. "But I did promise an inspection, didn't I?"

"What're you — Soshiro!"

He moves too quickly for you to react, pressing another hard kiss to your lips — his tongue dipping in to draw out a startled moan — before he's suddenly kneeling at the edge of the bed, yanking you closer by your legs spread on either side of him. "The heels look nice," he says conversationally, dragging his hands up your calves.

You suddenly feel over-sensitive, your nerve endings straining into his touch as he leans forward to drag his nose along the inside of your thigh. "Ah— Soshiro, that tickles!"

"They make your legs look good," he continues, as if you hadn't spoken. You raise up on your elbows to glare down at him as he brushes his lips featherlight against your thigh. Soshiro smirks and turns his head to nip the skin there, kissing and sucking along your thigh as he slings your leg over his shoulder for easier access.

Oh, shit.

The whine you let out would be embarrassing except that Soshiro mutters a curse and shoots you a look that makes your core clench tight. You reach for his hands, desperate for some leverage or an anchor, and he lets you take one of his hands but uses the other to hike your other leg over his shoulder.

"This is cute," Soshiro remarks, looking intently at your panties and the damp spot clearly evident even in the dim light. "Were they expensive?"

What is he asking? Why would it matter when the only thing you can focus on is the incessant ache in your core, inches away from his touch, heartbreakingly empty and wet and hot —

Soshiro rips your panties with one hand and tosses the flimsy scraps of cloth aside, exposing your fluttering core to his hungry gaze. You shift desperately, torn between wanting and wanting to hide, but before you can voice a request Soshiro dips in and licks you.

"Oh, fuck —" you moan, collapsing back on the bed as your hips buck up into the friction. Soshiro licks at you sloppily, digging his tongue into every inch and fold of you as he groans.

"All this for me?" he murmurs, catching your eye as you clutch desperately at the blankets. "Only for me, right, melon drop?"

You nod shakily as he gently kisses the throbbing bundle of nerves at your core. "I'm yours, Soshiro," you gasp. The waves of pleasure building in your body are frightening, your heart pounding hard, but you can't help tilting your hips closer to him. "Please, Soshiro — I… I can't —"

"Hah — fuck you," Soshiro groans. "Hold on to me."

You barely get a moment to register his command before he dives back in, targeting your clit and sucking on it as you sob with pleasure. White hot electricity races through your veins as you scrabble desperately for something to hold on to, grabbing at the purple strands of his hair and rocking your hips as he devours you.

You feel the burning touch of his finger as he drags it along your lower lips, making you suddenly hyper aware of how empty you feel. Your insides clench futilely, your fingers twisting into his hair painfully as you moan and beg. "Soshiro, Soshiro please —"

You can hear the squelch of your wetness as he finally slides his finger inside you, poking and prodding your walls until he presses against something that makes you see stars. Your back bows off the bed as you pant and squirm.

"There ya go," he grunts, pulling back to fix you with a burning red stare. "Let go for me, honey. I've got you."

You clench around his finger as he adds another, the intrusion unfamiliar but welcome, pleasure spiraling and spiking through you as he flicks his thumb over your clit and presses against that spot just right. It's — it's too much — too overwhelming —

Soshiro sucks your clit between his lips again and you shoot over the edge with a shout.

"Good fucking girl," Soshiro murmurs. You can barely hear him beyond the fuzzy aftershocks, but the words bleed warmth into your face as you melt into the mattress. He carefully licks you clean, chuckling when you whine at the overstimulation.

"Soshiro?"

"Yeah?" He climbs back over you, the lower half of his face shiny with wetness. It should be gross, but you're so boneless you can't even bring yourself to care as he leans down to kiss you, tongue tangling with yours as you moan at the taste of yourself.

"Where'd you… where'd you learn how to do that?" you mumble tiredly.

"In my dreams," Soshiro says, laughing when you pout at him. "I've been dreaming 'bout you for ages, y'know. But most of the technical stuff was from locker talk with the guys."

You nod and glance down, but the angle is awkward and you can't quite see —

"Ah, don't worry 'bout me," Soshiro ducks his head and you stare at the pink flush rising up his neck. "I'm gonna hafta meet you at the ballroom, hazelnut. I need a change of pants."

"Oh," you nod, wide eyed and blushing as he snorts. "Sorry?"

"Don't apologize for bein' a dream come true," he says. "But we should really go soon, or the captain'll have both our heads."

Soshiro helps you stand on wobbly legs as you regain your balance on heels, kneeling to smooth your dress back down your thighs. "Wait — what about my panties?"

He tilts his head thoughtfully. "Right, I'll help ya with that."

Soshiro's touch is warm this time, not burning hot, and the kisses he presses along your thighs are more ticklish than anything. He grins up at you as you giggle. "Will we tell Captain Ashiro after the party tonight?"

He rises and his gaze goes to your neck and shoulders, exposed by the straps of your dress. Something sharp and pleased settles in his smile. "I don't think we'll need to worry 'bout it. Any fool who gets close to ya when you're marked up all pretty for me is askin' for trouble."

… What?

You look past him to the mirror and gasp. All those little bites from earlier are blooming pink and purple beneath your skin. Soshiro laughs, swoops forward to kiss your scolding right out of your mouth, and pulls away only after you've melted back into his arms, pliant and breathless.

"You passed inspection, by the way," Soshiro adds, smiling a little lopsided and fond. "Congratulations on becoming the Third Division Vice Captain's fiancée."

Your eyes widen. "Fiancée?"

"Oh, too soon? We can start off with 'girlfriend' first."

"Soshiro…"

"What? A guy's got dreams, alright?"

You laugh. "You didn't even propose!"

"Alright, fine," he kisses you again and you beam, delight and happiness swooping through you at how easy it all feels. "Keep that third finger on your left hand empty for me, apricot."

"It's a promise."
