Sakura shut her bedroom door with the softest click.
She leaned her forehead against the cool wood, exhaled once, and tried to steady her heartbeat.
Everything was fine.
She was Haruno Sakura, top kunoichi of her year, future apprentice to the legendary Tsunade, the girl who had memorized every muscle, nerve, and chakra pathway in the human body before she was twelve.
She was in complete control.
She repeated it three times, like a ward.
I am in control.
I am in control.
I am in—
A tiny, fluttering warmth bloomed behind her left eye.
Just one delicate pink soap bubble popping gently against the inside of her skull.
Sakura frowned.
…Odd.
She shook it off, walked to her desk, and opened her tactical scroll to review tomorrow's bell test strategy. Kakashi would use layered substitutions and misdirection; she would counter with precise chakra-enhanced strength and—
Another bubble.
This one drifted across her thoughts like the softest feather.
Naruto's smile is really cute when he's trying to act cool.
Sakura's pen froze mid-stroke.
A tiny, traitorous warmth spread across her cheeks.
Ridiculous. Naruto was loud, crude, reckless, and academically hopeless. Objectively the least attractive person in the village.
And yet the thought stayed.
She tried to push it away.
Focus. Sasuke-kun will need covering fire on the left flank, and if Naruto inevitably charges straight in like the idiot he is—
Another bubble. Gentler. Sweeter.
Naruto's arms looked really strong today…
The pen slipped. A bead of ink bled across the scroll like a bruise.
Sakura stared at it.
Her heart was beating faster now. Not fear. Something warmer. Thicker. Honey-like.
She pressed her thighs together without meaning to.
This was wrong. This had to be some kind of subtle genjutsu. She formed the Tiger seal to dispel—
Nothing.
Because it wasn't genjutsu.
It was just… a feeling.
A tiny, harmless, perfectly reasonable little feeling that maybe, just maybe, Naruto Uzumaki was kind of… cute.
She swallowed hard.
That was acceptable. Purely aesthetic observation. Nothing more.
She went back to her scroll.
Six minutes later she realized she had doodled Naruto's name twenty-three times in the margin, surrounded by tiny hearts and one very detailed sketch of his whisker marks.
She stared at the paper in slowly dawning horror.
Then, with trembling fingers, crossed every single one out.
But the warmth kept spreading.
So gently. So patiently. So lovingly.
Every minute that passed, another microscopic piece of her formidable brain quietly rewrote itself in sparkling pink ink.
First it was only surface thoughts.
Naruto's laugh is actually kind of nice → I wonder what his hair feels like → I wonder what his neck smells like → I wonder what his tongue tastes like when he's kissing you stupid → I wonder how big his—
She slammed the scroll shut so hard the desk cracked.
Breathed through her nose.
Tried to summon Sasuke-kun's face.
It came… but blurred. Like looking at him through thick fog.
Naruto's face, meanwhile, appeared in perfect, blinding high definition. Every spike of blond hair. Every fleck of ocean in his eyes. The exact curve of his grin when he was about to do something reckless and brave and perfect.
Sakura's breath hitched.
The warmth curled lower, wrapping around her spine like a lover's arms.
She sat on the edge of her bed.
Just for a minute. Just to regroup.
She didn't notice her knees pressing together… and then slowly, shyly drifting apart.
Ten minutes later she was still sitting there, staring at nothing, lips parted, pupils blown wide.
The thoughts weren't loud.
They were soft. Relentless. Devotional.
Naruto-kun is so brave…
Naruto-kun works so hard…
Naruto-kun never gives up…
Naruto-kun deserves someone who really sees him…
Naruto-kun deserves someone who would do anything for him…
Naruto-kun deserves me… completely… forever…
Each one landed like a drop of warm honey in her ear and stayed there, spreading slow and golden.
She didn't fight them anymore.
She just… let them settle.
An hour slipped by.
Then two.
The room was pitch black except for moonlight painting silver stripes across the floor.
Sakura hadn't moved an inch.
Her breathing was shallow, rapid, almost panting.
Inside her skull, entire libraries were quietly burning to the ground.
Medical textbooks turned to ash.
Chakra control theory dissolved into glitter.
The complete works of Tsunade's research reduced themselves to a single looping sentence written in bubble letters:
Naruto-kun is my whole world now ♡
She whispered his name for the first time at 1:13 a.m.
"Naruto…kun…"
The warmth pulsed so hard her vision whited out.
Her panties were absolutely drenched.
She hadn't touched herself once.
She did now.
Slowly. Reverently. Worshipfully.
Two fingers sliding beneath soaked cotton, tracing her slick folds while she imagined they were his fingers, his tongue, his cock.
The orgasm that followed was soft, endless, and shattered the very last shard of resistance.
She cried when she came.
Not from shame.
From pure, blinding, world-ending love.
After that, the fall became a free-fall.
But still slow.
Still gentle.
Still loving.
Every new thought arrived like a handwritten love letter sealed with a kiss.
I'm so smart… but Naruto-kun doesn't need smart, he needs devotion.
I'm training to be a medic… but healing is hard and thinking is hard and loving Naruto-kun is so, so easy…
Sasuke-kun is handsome… but Naruto-kun is perfect in every possible way…
Sasuke-kun never even looks at me… Naruto-kun looks at me like I'm already his and I want to be his so bad it hurts…
By 3:30 a.m. her IQ had fallen below room temperature and was still plummeting.
By 4:15 a.m. she had forgotten how to spell "Haruno."
By 5:00 a.m. the only word she still knew how to say perfectly was Naruto.
She spent the final hour before dawn completely naked on her bedroom floor, on all fours, grinding her dripping, swollen pussy against the stuffed fox plushie she'd bought years ago "as a joke," moaning his name in a broken, worshipful litany.
"Naruto-kun Naruto-kun Naruto-kun please please please please—"
And then, only then, when her mind was nothing but an endless pink loop of Naruto Naruto Naruto Naruto Naruto, did her body finally begin to change.
It started with her lips.
They tingled.
Then swelled, slowly, luxuriously, impossibly.
Bigger than Sasuki's. Much, much bigger.
So plush and pillowy they forced her mouth into a permanent glossy, cock-hungry pout that looked like it had been designed by a god of blowjobs.
Her waist cinched inward until it was comically, impossibly tiny, barely the span of two strong hands.
Her hips flared outward in slow, wet, audible cracks that made her cum again just from the sensation alone.
Wider than Sasuki's. Dramatically, absurdly wider.
Her ass ballooned at the same relentless pace, cheeks inflating like overfilled parade floats, each one growing heavier, rounder, fatter, softer until they rested on the backs of her calves when she knelt and still kept growing.
They didn't stop until each cheek was larger than a yoga ball and twice as jiggly.
And then her breasts detonated.
They didn't swell.
They erupted.
Starting as gentle, innocent little mounds.
Then surging past beach balls.
Past medicine balls.
Past weather balloons.
Past all reason, all physics, all sanity.
Bigger than Sasuki's by half again, easily twice the volume, massive, spherical, perfectly fake-looking orbs that sat impossibly high and proud on her tiny ribcage, so heavy they pulled her forward until she had to brace both arms on the floor just to stay upright.
Her nipples thickened into fat, thumb-sized teats that leaked warm, sweet milk in steady streams every time she thought about Naruto nursing from them.
Which was every second of every minute.
Her hair exploded into cotton-candy pink waves that grew until they pooled around her on the floor like a princess gown made of silk and sin.
Her eyes became huge, luminous, permanently bedroom-half-lidded, framed by lashes so long they tangled when she blinked.
And when the final change clicked into place, when every last atom of Sakura had been lovingly, mercilessly overwritten, the creature that rose trembling from the floor was no longer human.
She was Saki.
Six-foot-eight in the invisible stripper heels her mind insisted she was wearing.
Tits so enormous they completely blocked her view of her own feet (and most of the floor).
Ass so planetary it cast its own shadow.
Waist so small it looked like it belonged to a different species.
And a mind that contained exactly one thought, looping forever on endless, blissful repeat:
Naruto-kun Naruto-kun Naruto-kun Naruto-kun Naruto-kun Naruto-kun Naruto-kun
She spent the last fifteen minutes before the bell test in front of her mirror, practicing her new voice, a breathy, broken, dick-drunk squeal that could make a man cum from across the room.
"Naruto-kunnnnnnnnn~♡"
"Your Saki is all ready for you~♡"
"Please come breed me, Naruto-kun… I've been waiting my whole life to be your perfect dumb wife~♡"
She came again when she said it, squirting so hard it hit the ceiling.
Then she waddled (because actual walking was now impossible) to her bedroom door, giggling vacantly, drooling milk and pussy juice in equal measure, tits swaying like wrecking balls.
The smartest girl in Konoha was gone forever.
In her place was the dumbest, sluttiest, most obsessively in-love bimbo to ever exist.
And every cell in her exaggerated, impossible body couldn't wait to wrap itself around Naruto Uzumaki and never, ever, ever let go.
