The Femdom's Orgasm Control, and the Chastity Device
After uttering those chilling words, So-hee spat into Juhwan's splayed open mouth, again and again, until he had no choice but to swallow whatever she fed him in silence.
"Get up."
A single command. That one sentence made Juhwan spring to his feet without so much as a squeak of protest. So-hee seized his cock in her fist, slid down his zipper with a smooth hiss, and pulled out his cock, still soft and unaroused.
So-hee: ....
Without a word, she began stroking the limp thing in her hand, kneading it until his shriveled cock, unable to resist, started swelling little by little.
"I've told you over and over, haven't I? That fucking cock of yours belongs to me. I told you not to go rolling around with any other bitch."
And yet So-hee had seen it — Ji-hee stepping out of the officetel.
"Got an excuse?"
Juhwan: .........
When he didn't answer— SMACK! So-hee's palm cracked across his face once more.
"Answer me."
".........No.."
"Kneel."
The moment her command fell, Juhwan dropped to his knees on the stairs, cock still hanging out of his pants. So-hee stood over him, gazing down, the bare skin of her legs peeking from beneath her skirt, the toe of her shoe brushing the inside of his thigh.
"You made me feel like shit, so you're going to take a real punishment, aren't you? I was already in a fucking terrible mood today. You picked the perfect day to get caught, you little bastard."
"You are absolutely not cumming today. Not until I give you permission."
She pressed the tip of her shoe against his crotch. Slowly, almost grinding.
"Understood?"
"....Yes..."
SMACK!!!!
Another vicious slap, harder than the last.
"Who the fuck told you to talk down to me?"
".....I'm sorry."
So-hee had been the one, back when her heart was drawing closer to Juhwan, who'd told him to drop the formalities and speak casually with her. But the So-hee of now — of this moment, of that time — was long dead.
"Take off your pants."
When her decree fell again, Juhwan, backed into the corner this time, stripped them off completely. Once he'd done so, So-hee lazily dragged the toe of her shoe back and forth across his crotch and his cock. Feeling it begin to stir under her touch, the corners of her mouth curled upward.

"You filthy animal, getting hard already?"
"Our poor puppy... that must hurt, hm?"
It wasn't sympathy in her voice — it was verification. She kept tapping the head of his cock with her shoe, light little kicks, as she went on.
"I'm going to teach you the rules."
"First — no matter what I do to you, you do not cum."
"Second — you do not cum until I say you can."
"Third — you know what happens if you break them, don't you?"
"......Yes.."
"Crawl up after me."
So-hee left him there and climbed a short way up the stairs alone. Juhwan, pants entirely gone, crawled up on all fours like a dog and knelt before her once more. The moment he arrived, So-hee seized his head and shoved it between her legs. Beneath her skirt, she hooked her panties aside, and bare flesh pressed against his mouth.
"Lick."
Juhwan began lapping away without a word. It was a more timid going-down than usual, and compared to the expressions she wore during their ordinary sex, So-hee's face today was far colder.

Juhwan: *Shluuurp... shk...*
The stairwell corridor filled with nothing but the wet, obscene sounds of Juhwan's mouth. So-hee merely gazed down at him with frigid eyes.
"Not good enough."
She grabbed his head, yanked it free of her pussy, and delivered another stinging slap.
"You're being punished right now. Get that through your head. A pup getting punished can't even eat pussy properly? I'll give you one more chance. Suck."
Only then did she release the fistful of his hair she'd been gripping. Juhwan buried his face between her thighs again and worked twice as hard, more earnest than he'd ever been with any pussy he'd ever tasted in his life.
If this had been the usual So-hee, she'd have been writhing wildly by now, spewing filthy words, her eyes rolled back in her head. But So-hee held out. Once more she seized his hair, tore his face away from her crotch, and said,
"I was going to let a decent tongue job slide, but apparently you're just a worthless piece of shit, aren't you?"
"On to a harsher punishment. Look forward to it, you pathetic thing."
Then So-hee hauled him up to his feet. His cock was standing bolt upright, and she knelt in front of it and swallowed him whole.
And she didn't stop there — she used her teeth, chewing and gnawing at Juhwan's cock, slow and deliberate.
"AAAAGH!!! Ah.. it hurts..!!!!"
He wanted to scream, but he couldn't. They were in the officetel stairwell — one loud cry and someone would come out and witness this exact scene.

So-hee: *Mmm... shluup... schluuurp*
Still keeping that icy expression, So-hee switched to a skilled, practiced blowjob, her mouth sliding over Juhwan's cock. This was not the cocksucking she gave him during their usual sex — right now her tongue was even more ferocious than that.
"Haa... haa..."
Juhwan's breathing turned ragged and his body began to go rigid.
"F...fuck...!"
Right on the verge of ejaculation — So-hee pulled her mouth off his cock. Then she drove her fist up into his balls like an uppercut.
"G— GAAAAAAGH!!!!!!!"
Juhwan collapsed under the unbearable pain, writhing on the ground.
"You animal — when did I give you permission to cum?"
"Ghhhkk...!!! Hk... hhh...!!"
Whatever curses she threw at him, Juhwan was down for the count, clutching his balls, rolling helplessly in the agony.
"...Fuck...!! That's still going too far...!!"
"Oh? Still got some fight left in you? Not enough punishment, is it?"
".......Th...that's..."
So-hee stepped toward the suffering Juhwan, seized his head in a vice grip, and leaned in close.
"In case you forgot — until I say so, you never get to cum. Ever. You try to blow your load one more time? I'll make sure you never breed in your life."
With that, she began stroking his cock again with her hand — a terrifying kind of tenderness.
"Oh, look, it's still alive?"
This time she let a long string of drool spill from her lips onto his cock, and with the shaft slick and gleaming, she began a merciless handjob. Her fingers, wrapped tight around Juhwan's cock, slid ruthlessly up and down, stroking and milking him — and every so often the rhythm would stop, and she'd rake her palm roughly over the sensitive slit of his urethra, tormenting his most vulnerable spots above all else.
"Ghh... ghhuuk...!!!"
"Hold it in, you rutting animal."
Tears began welling up in Juhwan's eyes. And So-hee noticed.
"What are you crying for already? I haven't even started the real punishment yet."
Again she swallowed his cock whole, and with her merciless tongue-work she melted him completely.
"Ghhhkk...!!"
It was about to happen again — he was going to cum — and he had to fight it with everything he had. Because if he failed, So-hee had something truly terrible planned for him.
The moment she felt his body react once more, So-hee pulled her mouth away and clamped her fingers hard over the head of his cock, sealing his urethra shut.
"Don't you dare cum. Cum and you die."
"Uuuuuhhhh....."
He held it. He barely, barely held it.
...Just as he was thinking he'd made it, So-hee's hand started working him again.
"Uuuuh..!! N—no!! I'm gonna— I'm about to...!"
Her hand let go again.
Edging. That was all it was — a femdom running her own personal male sub through orgasm control.
His cock twitched and throbbed in torment while So-hee simply watched it suffer, savoring every second. And just when his cock seemed to calm down — the handjob would start again, then the oral, then the stop right before the edge. Over and over, until Juhwan's eyes rolled back in his skull and his mind was entirely under her control.
"Haa... pl...please...... let me cum now........"
"Surrendering already, when the real thing hasn't even started? Disappointing, lol. If I'd known you were this pathetic, I never would've started anything with you in the first place."
With that, So-hee climbed on top of him where he lay, rolled her long skirt up, and spread herself out before his eyes, her bare pussy in plain view.
"Look. This is what you're looking at."
Juhwan: ....
Gasping for breath, barely clinging to a focus that had utterly abandoned him, Juhwan stared at her pussy.
"Now, with this pussy, I'm going to pound you until I milk out every last drop of that filthy cum of yours."
"But there's a condition."
"And I don't think I need to spell out what it is, do I?"
This was So-hee's method of taming a man. Right on the edge, right at the precipice — always promising release, then yanking it away at the last second. Most men, stopped dead the instant before climax, will lose their minds completely. So-hee understood that weakness better than anyone.
Juhwan was no different. He'd been dragged to the brink again and again and never allowed to cross. If, all this time, he'd simply buried himself in her pussy whenever he was horny and fucked her to completion, then the So-hee standing before him now would never have ascended — from living sex toy to his owner and master.
And what did he have to do to finally be allowed to cum?
Juhwan knew perfectly well, without her having to say a word. He'd done this with her before — lines like these were a piece of cake.
".....M...Master..... I was wrong."
"This worthless dog of yours... please forgive me, just this once... and please... let me cum..."
Hearing that, So-hee positioned her pussy hole precisely over the head of his cock. But she didn't take him in. She simply rested his tip against her entrance, sat there perfectly still, and looked down at him.
"Good boy."
"But was that really your best?"
"That's all you've got? Think hard, you pathetic fuck. You can do better than that, and you know it."
"If you don't want to, then quit. We end it here and I just walk away. Simple as that."
Juhwan: ......
He had to abandon it — himself. To release these starving, howling desires, he had no choice but to let go of every last shred of who he was.
Juhwan: .........
".....Master... please... fuck your dirty, wretched dog... with your holy pussy..."
"If you'll milk out every last drop of my cum...... I'll do anything you command... anything..."
"I was wrong, Mistress So-hee......... please, forgive me, just once..."
"Pfft... hahaha"
The instant the words "Mistress So-hee" left his mouth — SLAM! — she dropped her weight down onto his cock.
"Ugh—!!"
Juhwan's cock was already buried deep inside So-hee's pussy. She lifted her legs and rode him hard, slamming her hips down until the sound of flesh smacking flesh filled the stairwell — puck, puck, puck!
But her expression stayed ice cold as she stared down at him.

Grind down, roll her hips, grind down again, roll her hips again. As the motion repeated over and over, Juhwan—
".,.M..Master.... I'm... I'm gonna—"
Before he could even finish the sentence, So-hee sprang up off him. His cock slipped wetly out of her pussy.
"You're so fucking funny, you know that? When did I ever say you could cum??"
"Ha... haa.... pl...please....."
SLAM! Once more she dropped onto him, swallowing his cock to the hilt.
"Uuuuuuhhhh!!!!!"
The moment Juhwan's body began to shake all over again, she leapt off him.
"Pl...please.... I'm going insane, I swear......!!!!"
So-hee was starting to genuinely enjoy watching him come apart. And when Juhwan finally begged her through tears, she leaned down and whispered right into his ear.
"Aww... you poor thing... crying because you want to cum so badly? Is that my little puppy?"
"But you see......... I, well... I have no use for a horny dog in heat who abandons his master and goes out humping every other female he can find."
"You weren't getting to cum today anyway. That was never on the table."
Then So-hee reached into her pocket and pulled something out.
"Get up."
Juhwan, the focus completely gone from his eyes, was too far gone to respond.
"I said get up, fucker. Don't make me say it twice."
Barely managing to push himself off the ground, Juhwan rose and stood before her. And then he looked at the unidentified object in her hand.
"...Wh...what's..."

It was a chastity device.
Before he could even ask what it was, So-hee snapped it shut around Juhwan's cock — click — then pulled up his pants and zipped them closed for him, kindly.
"N...no....."
Even if she denied him here, he could have gone home and jerked off — that had been his one remaining escape. But So-hee had shut that door too, completely.
With the device locked around his cock, So-hee twirled the little key in front of his eyes, dangled it, taunted him with it.
"Think long and hard about what you did wrong today."
"And write me a handwritten apology — fifty pages. No, make it a hundred."
"Then...... I'll think about whether or not I feel like unlocking this. Heh."
With that, So-hee turned and started walking up the stairs toward her unit.
"N—Noona... wait..! Please.....!!"
But she ignored him. Completely ignoring his sobbing pleas, So-hee simply opened her front door, stepped inside, and was gone.
Juhwan: .......
Unlike moments before, the corridor now held nothing but silence.
Around that time—
Inside So-hee's unit, So-jin stood before the mirror wearing the swimsuit that had come in the delivery box, a phone camera raised in her hand.

So-jin: "Lol~~ so cute, haha"
So-jin: "This summer I'm wearing this out and luring in all the guys with insane bodies, and I'm gonna devour every last one of them lmaooo"
Just then the front door opened and So-hee walked in.
So-jin: "What's up~ unnie, lmao? Weren't you taking out the trash? How does throwing out trash take this long?"
"Went out for a smoke?"
So-jin: "A smoke~ no matter how many cigarettes you puff, you don't come home this late~ Be honest, unnie, lol. What were you doing downst—"
BANG!
So-hee, at the absolute limit of her fury, blew straight past So-jin, stormed into the master bedroom, and slammed the door behind her.
So-jin: "..Hah.. yikes, lmaooo what on earth has her that pissed off???"
So-jin's gaze slid toward the front door So-hee had just come through. Quietly, she padded over to it and cracked it open, peering out.
And the moment she did, she caught the unmistakable feeling of someone down at the far end of the stairwell flinching in alarm and scrambling away to a lower floor.
So-jin: "...Lmaoooo. Unnie.... what exactly have you been getting up to~?"
