My Weakness in Her Grip
My name is Seo Yu-na.
Of course, I hadn't been Seo Yu-na from the beginning.
Until just a few years ago, I was a man.
The name I went by back then was—
...No. There was no need to drag it up. The life I'd lived under that name had already ended without leaving so much as a trace behind.
"Senior dear."
Tap. Tap.
The dry sound of a fingertip drumming against a thin paper envelope pulled my dazed mind back into the present.
"Why ever has your face gone so pale, I wonder?"
Ryu Yi-na, perched on the edge of my bed, twisted the corners of her mouth up into a smirk.
Her bleached silver-gray hair, chopped into an edgy wolf cut that just grazed her nape, drifted lightly with the movement, and the silver piercings studding her ear caught the fluorescent light and flashed. Beneath an open dark denim jacket she wore a thin black cropped top, and the smooth stomach it left bare—blatantly displaying ridges of hard muscle with every breath she drew—marked her, beyond any doubt, as a Sports Science student.
I had always thought of her as a girl you couldn't help but notice. A physique that stood well over five foot seven on a woman's frame, a supple body honed by training, and a brash, devil-may-care personality that sassed everyone without discrimination.
More than anything, she was a junior who had, to an almost eerie degree, doted on me.
At least—that was what I'd believed, right up until today. Until this very moment.
"...Yi-na."
My lips had gone bone-dry, and my voice scraped out cracked.
"Where... where did you get that?"
Yi-na cast a languid glance down at the corner of the document envelope in her hand.
Then her brown eyes danced, brimming over with mischief and an undisguised, sensual curiosity.
"Oh, this, you mean?"
When I froze, unable even to breathe, she slid a long finger into the envelope and slowly drew out several sheets of paper.
The dry rasp of paper against paper rang out like the toll of a bell announcing a death sentence.
The first page: a community service order.
The second: treatment records for abnormal hormonal impulse control.
And at the top of the third page—
The letters sat there, printed sharp and vivid, as if bled through with ink.
...
My breath seized up from somewhere deep inside my body.
Those documents were supposed to be buried in the deepest corner of a drawer in my one-room studio, entombed beneath a pile of old junk as if sealed away for good. The only reason I hadn't thrown them out was the off chance I might need them for some administrative procedure or as proof for my readmission—and I had never once looked at them again. They were the shameful residue of a past I wanted erased.
And now they were fluttering, light as feathers, at the fingertips of a junior from my own department.
"Truly remarkable, isn't it, senior dear?"
Yi-na flicked her wrist and let the papers flap.
"A complete feminization procedure over a hormone problem—my, what a wonderful world we live in. Finding out my senior used to be a man was shocking enough, but never in my wildest dreams did I imagine you'd be carrying such a scandalous little criminal record on top of it, you see."
My heart plummeted, slamming straight down past the soles of my feet.
"Keep your voice down... please."
"Who's going to hear you in this cramped little place you live in all by yourself, hmm?"
"Even so... nnh."
"Mmhm."
Yi-na's chin tipped upward.
Without thinking, I crossed my arms over my chest. Even through the loose knit of my sweater, the soft curve filled my palms with a weight I could feel, heavy and full.
A woman's breasts—something my body had never once possessed before.
Years had passed, and still, every time I showered or stood in front of a mirror, this body wrapped me in an uncanny wrongness cold enough to raise gooseflesh.
The procedure had been a little too successful. My skeleton had been subtly planed down, narrowing my shoulders; the hardened muscle had dissolved under the flood of hormones into soft, yielding fat. The heavy lines of a man's face had been reborn as the delicate, pitiable features of a fresh-faced beauty, and my chest and hips had swelled plusher than most women's ever were.
Because my body was, constitutionally, abnormally receptive to female hormones, no one had ever once suspected I had been a man.
Seo Yu-na.
Twenty-six years old, a fresh-faced young woman returning to school a little later than most.
That was the mask I showed the world.
The only ones who knew the truth of my past offense and the forced procedure were supposed to be the state and the hospital.
And I had believed I could go on hiding behind that shell forever.
"...How much of it did you read?"
"How much did I read, you ask?"
Yi-na giggled and rocked her ankle.
"All of it. Every last word—gave it a very thorough close reading, you see."
"Yi-na..."
"Why are you trembling like a leaf in the wind, hmm? Like someone with a crime on her conscience."
Yi-na clicked her tongue lightly and leaned back against the headboard.
I chewed my lip until it nearly bled and let my head fall.
A few years ago, I committed a sex crime.
It wasn't a violent felony—just indecent assault, a transgression born of an impulse I couldn't beat down.
But the diagnosis found that a severe abnormality in my endocrine system left me utterly incapable of controlling my sexual urges, and instead of leniency, the court shoved forward a grotesque institution: forced feminization, conditional on treatment.
Rot away in a facility for the rest of my life—or have my body completely rebuilt and return to society.
In the end, I chose the latter.
And so the man's body was castrated, utterly, and died.
On paper, and on this very skin.
"Come now—no need to make a face like you're about to die."
Yi-na tapped the papers into a neat stack and tucked them back into the envelope.
"Did you take me for some wicked girl who'd drop an anonymous tip on the campus app just to watch you crash and burn right before her eyes, hmm?"
"...You mean that?"
"Yep."
The answer was so light it made the strength drain out of me.
Just as a faint thread of relief began seeping into the crushed, over-pressured depths of my chest—
"In exchange."
Yi-na rose from the bed.
In an instant, the whole current of the room changed.
With that supple, athletic grace that was hers alone, she strode across the floor of my tiny studio.
As she bore down on me, a bitter-sweet scent of sweat and perfume washed over me in a rush.
Some primal instinct read her as a threat, and I stumbled backward.
One step. Two.
Thud—my back hit the cold wall.
"Wh-what are you doing..."
"I do believe we ought to make a little deal, you see."
Yi-na planted her palm flat against the wall, caging me inside her arms.
There had never been any escape route to begin with.
"I'll carry that juicy, scandalous little record of yours with me to my grave, senior dear."
Her whispering breath skimmed past my ear like a lick of heat.
"That you used to be a man. Why you became a woman. What punishment you received because you couldn't keep that precious lust of yours in check... I'll bury it all, every last scrap of it, you see."
"Then... what is it you want?"
Was she going to shake me down for money?
My mind went white at the thought that she might demand I take out a student loan for her—and in that instant, Yi-na let out a short, hollow laugh.
"There's just the one condition, you see."
Her finger traced slowly down my collarbone.
"This prettied-up body of yours. And that filthy appetite that got you punished because you couldn't hold it in... from now on, you don't go spilling it anywhere else. You pour it all out, nice and obedient, for me and me alone. Won't you be mine exclusively, senior dear?"
"...What?"
My brain whited out, paralyzed.
"I've liked you for quite a while now, you know. Fell for you without even knowing you'd been a man—but after reading those papers, well, you're even better than I dreamed. A female sculpted perfectly to my taste."
Yi-na rolled her eyes up in a look of naked want and seized my hand, dragging it toward her.
A hot hand, calluses pressing hard into my palm.
Inside that heat, boring in without leaving me a crack to refuse through, Yi-na pressed her lips flush against my ear.
A shiver ran down my spine.
The word like meant nothing here. This was, unmistakably, a predator's trap.
Clenching my trembling jaw, I managed to squeeze the words out.
"Ryu Yi-na."
"Yes, senior dear?"
"That's... that's blackmail."
In that instant—
the sly playfulness hooked on the corners of Yi-na's mouth vanished like a mirage.
...
The air in the room sank, frigid, as though it had frozen solid.
Yi-na's brown eyes went cold, then radiated a chill that crawled over my skin—the look of someone gazing down at an insect wriggling at her feet.
"Ha."
A low, empty laugh.
Yi-na tilted her head slowly, roughly toying with the silver piercings along her ear.
"Senior dear. No... Yu-na."
The cold, dropped register of her voice cracked against my ear.
"Seems you don't understand your situation one bit."
"...What?"
Just as I recoiled in panic, that iron grip closed over my left nipple, jutting against the loose knit of my sweater, and squeezed it upward without mercy.
"Ahhk, ah...!"
"Because I smile and call you senior, senior... you still think you're the big important senior here, don't you?"
A merciless grip that felt ready to tear the flesh clean off sent a jolt of pain lancing through my whole body.
Yi-na ground her strength into her fingertips and twisted the nipple that stood rigid through the fabric, bending it cruelly.
"Nngh, nnh...! Yi-na, it hurts, let go...!"
"I'm squeezing it to make it hurt. Why would I let go?"
Yi-na seized my jaw in a vise and hauled my face up to hers.
Her hot breath poured down over my quivering lips.
"If you don't want your life buried for good the moment word gets around that a former sex-offender bastard got rebuilt into a woman and has been scurrying around campus playing the innocent... then from today on, you behave for me. Understood?"
Before the words had even finished, her rough hand plunged, unchecked, into the inside of my panties.
"Ha, wait...! Don't touch me, nnh...!"
"Oh my? And what is all this?"
What her fingertips found inside the crotch of my thin panties was my most private flesh, soaked so thoroughly it squelched, slick and gleaming.
Even as terror made my jaw chatter, my lewd body was answering the sadistic violence all on its own, dribbling out its juices in shameless little spurts.
Yi-na drew out her dampened fingers and thrust them up in front of my eyes, making a show of it.
With a lewd, squelching friction, clear mucus stretched in sticky strands between her fingers.
"Yu-na. A bastard who got hauled before a court and cut off for groping women's bodies—and even turned into a female-bodied thing, you're still leaking down here like a tap left running?"
Yi-na sucked the fluids from her fingers, long and slow, loud enough to be obscene, her red tongue curling around them.
Her eyes had already turned into the ferocious gaze of a beast that had swallowed its reason whole.
"With a body this perverted and this shameless, well... I suppose there's nothing for it. From today on, I'll just have to train this body of yours properly, top to bottom, with my own two hands."
Zziiiip—
The rasp of a zipper tore through the silence, and the front of Yi-na's gray wide-leg pants came undone in a single motion.
What sprang free from within, bouncing up heavy, was a thick, ferocious cock well over eight inches long.
Dark veins bulged angrily along the red, menacing shaft, and from its tip, clear precum was already dripping down, drop by drop, beyond her power to hold back.
"...!"
At that massive thing—something that could never have hung from a woman's body—my breath jammed in my throat.
Yi-na slammed her hands down on both my shoulders, forcing me to my knees on the cold floor.
"Kneel properly, Yu-na. In exchange for keeping your dirty little secret from today on... every hole in your body becomes my own personal cock-sleeve."
