If You Wanted to Cum That Badly, You Should've Said So
Squelch... schlick...
Whatever resistance there had been at the start was a distant memory now. The dildo thrashed at will inside Han Seoyeon's pussy, and Yoo Jimin kept a hard grip on her hips, snapping her own waist deep and fast as if she meant to punch straight through to the mouth of her womb.
"Nngh! Mmph! Nn, nngh...!"
Han Seoyeon writhed against the pain, against the alien thickness filling her. Her body rocked with a will that was not her own. Slick fluid ran down her thighs. Screams died against the gag. Every last sensation was a humiliation beyond words.
Looking down at that wreck of a girl, a wicked little smile curled across Yoo Jimin's lips.
"Huh?"
She put on a deliberately exaggerated voice and stopped moving. Then she drew the dildo almost all the way out and shoved it home again. It slid in smoothly this time — nothing like the first thrust.
"What's this? You weren't a virgin?"
Yoo Jimin threw her head back and cackled as she mocked her. That laugh was a blade, carving straight into Seoyeon's heart.
"You put on that whole noble act all by yourself, but behind closed doors you were just a whore spreading your legs for anyone, weren't you?"
Jimin's fingers joined the dildo, teasing cruelly at the sopping mess of Seoyeon's sex. The moment those fingers started fiddling with her clit, Han Seoyeon's whole body jerked, a violent convulsion ripping through her.
"Mmph!! Nnnngh!"
She wanted to scream that it wasn't true — but her mouth was stopped by the gag. All she could do was glare up at Yoo Jimin, her eyes bright with fury and a raw, helpless sense of injustice.
Jimin drank in that look and drove the dildo in even deeper.
Thud! Schlick-schlick!
"How is it? Feel different from a real cock? Or do you like this better, hmm?"
The dildo scoured her inner walls with each vicious stroke, the question hanging in the air like a taunt. Little by little, something other than pain began to spread through her — a treacherous, melting heat.
Han Seoyeon shook her head with everything she had, trying to deny the pleasure. Her pussy, the traitor, gushed around the dildo and welcomed it in.
Yoo Jimin's hips never stopped. The moment she felt Seoyeon's resistance start to slacken, she drove the dildo deeper, faster, relentless. Han Seoyeon's pussy was already at its limit. The walls convulsed under the ceaseless onslaught of sensation, and hot fluid surged and spilled with every thrust.

"Nnh! Mmph! Nnnn...!"
The pain had receded somewhere far away. What remained was a pleasure so total it felt as if her mind were melting, flooding every nerve she had. She shook her head in desperate denial — but her body was honest. Her hips began to lift of their own accord, rising to meet Jimin's rhythm, taking the dildo in.
That reaction pulled Yoo Jimin's smile even wider, even crueler. She buried the dildo to the hilt and used the same fingers that had been teasing Seoyeon's clit to grind hard around the stretched rim of her entrance. Pleasure from the inside and pleasure from the outside hit her at once.
"Haaah...! Nnnngh...!"
Han Seoyeon's waist seized and shuddered. Her blue eyes rolled up, whites flashing. Something hot and violent came surging up from low in her belly.
Spurt!
Clear fluid shot from Han Seoyeon's pussy in a fountain. It ran down the dildo, soaked Yoo Jimin's hand, painted Seoyeon's thighs, and left the floor glistening and wet.
Han Seoyeon trembled in the aftershock, a fine, helpless shaking. Her pussy stayed clenched around the dildo, tiny convulsions refusing to die.
Yoo Jimin looked down at her with open satisfaction, eased the dildo free, and clicked her tongue.
"Oh my. You came. If you wanted to cum that badly, you should've said so."
She flicked the milky fluid clinging to the tip of the dildo onto Seoyeon's face.
"Our little princess has a much sluttier body than I thought."
Those were the last words Han Seoyeon heard before exhaustion took her and she collapsed.
Consciousness drifted back through a thick, receding fog. Han Seoyeon forced her heavy eyelids open. As the blur found its focus, the first thing that resolved was a ceiling — familiar, and yet not.
Her body felt wrong. Limbs that should have been slack were stiff, awkward, held in place. She tried to sit up. Nothing answered her.
That was when she understood. Both arms and both legs had been bound fast to the four corners of the bed by thick black leather straps. She was spread-eagled — utterly exposed, utterly helpless, a posture of pure humiliation. The disgusting gag was still wedged in her mouth. Not a scrap of clothing covered her. The sticky, foreign feeling between her legs was all the proof she needed that the nightmare had been real.
"Nngh... mmph!"
Fear and rage surged back in equal measure. She twisted with everything she had. The leather only bit deeper, leaving red welts around her slender wrists and ankles.
"Oh my. You're awake."
The door opened, and Yoo Jimin stepped through. A cup of water sat in her hand. The mockery from before was gone; what sat on her face now was a strange mixture of superiority and something that almost looked like pity. She came to the bedside and looked down at Seoyeon, who was still straining and groaning against the straps.
"Figured you'd be thirsty."
As she said it, Yoo Jimin unbuckled the gag. A ragged breath tore out of the newly freed mouth.
"T-take this off! Right now!"
Seoyeon's voice was wrecked, scraped raw.
"I can't do that."
Yoo Jimin shook her head and held out the cup.
"Master's orders. He said you'll be staying here from now on. Until you've been turned into a perfect bitch."
She cut off Han Seoyeon's pleading with a firm shake of her head, then sat on the edge of the mattress, studying her former friend with open interest — bound, stripped, and arranged for anyone's use.
"I'm the one who has to train you from here on out. If you lost it and came at me, I honestly don't think I could handle you."
The tone was almost gentle, the way one might scold a child — and cruel down to the bone. Her fingers stroked Seoyeon's cheek.
"Watching you earlier... you really, really liked cumming, didn't you?"
Yoo Jimin's eyes glittered with mischief. She stood, crossed to a duffel bag in the corner, and started rummaging through it.
"W-what are you trying to do..."
A bad feeling crawled up Seoyeon's spine. Her voice shook.
"Which is why I'm going to give you a little present."
Yoo Jimin drew several small, round objects from the bag. They gleamed silver, smooth and cold as bird's eggs. Vibrating eggs.
"Look forward to it, Seoyeon."
She took one egg in her hand and moved down between Seoyeon's legs. Settling herself between those bound, kicking thighs, she slathered the egg in a thick coat of cold gel — then, without a flicker of hesitation, pushed it straight into her pussy.
"Nngh!"
Seoyeon's body locked up at the sudden intrusion, that cold, round foreign weight. And that was only the beginning. Yoo Jimin took out a second egg and worked it into her ass the same way. Front and back — both holes filled at once with that dense, occupying pressure.
Last of all, she brought the remaining egg to Seoyeon's nipple. A small clip attached to the egg pinched down hard on the pink bud, biting like a vice.
"There. Now we start."
With every last piece of her little setup in place, Yoo Jimin flicked the switch on the remote in her hand.
Vvvvvvvvvvvmmmm—
In that instant, a vicious vibration tore through Han Seoyeon's entire body. Pussy, ass, nipple. Three of the most sensitive places she had, screaming at once — a storm of sensation violent enough to short out every nerve.
"And that's not even the end of it."
Yoo Jimin's face was bright with delight as she cranked the intensity higher. She bent, picked the red ball gag up off the floor, and wiped the clear thread of saliva from Seoyeon's mouth with the back of her hand — Seoyeon, still bound to the bed, already lost in the storm, past the point of forming a single coherent thought — then forced the gag back between her teeth.
"Mmph! Nnnnngh!"
The last scrap of protest that had managed to escape was crushed into a shapeless moan. But Yoo Jimin's "present" was not finished. She pulled a black blindfold from the drawer and covered Seoyeon's convulsing eyes completely.
All that remained for Han Seoyeon now was darkness. The moment her sight was cut, every other sense sharpened to a maddening pitch. The vibrations pouring out of her pussy, her ass, her nipples seized every nerve she had left.
"Mmph! Mmph! Nngh...!"
She was still trying to fight — Let go of me, you fucking...! — but Yoo Jimin ignored it without a second thought. If anything, the struggling seemed to amuse her. She hummed a little tune under her breath.
What she held in her hands now was a pair of oversized headphones. She settled them over Seoyeon's ears and turned the volume all the way up.
*slurp♥ schlick kiss smo-oooch squelch-squelch*
"Aaahn...♥♥♥... haaahn...♥♥♥♥♥"
In that instant, a woman's moans — vulgar, bottomless, belonging to someone she would never see — came flooding into Han Seoyeon's ears. Her mouth was stopped by the gag. Her eyes were sealed by the blindfold. Her ears were packed full of obscenity. The only world left to her was the vibration shaking her apart from the inside and the wet, filthy sounds hammering against her skull.
She could not see. She could not speak. She could not hear. The only thing still permitted to her was feeling — and she had been locked inside a perfect hell of sensation.
