Subjugating the Bully Girl (8)
"Hnnnnaaah..."
After sucking Dong-hyun's cock, Kim Se-bin climbed on top of him and rocked her body without pause, a hungry, restless rhythm that never quite settled.
"It feels so good... Master... ahh..."
She teased his nipples with her tongue, driving him into her with nothing but the roll of her hips.
"Nngh... good... so good..."
Every time her soaked pussy slapped against Dong-hyun's skin, a wet, filthy sound rang out through the room.

Dong-hyun palmed Se-bin's breasts and felt her around him. Compared to the women he had taken so far, it was not an especially remarkable sensation. Adrian and Sirian's insides had been crushingly tight, and Yuria had been a natural-born masterpiece in her own right. Se-bin was young, but she had clearly been around — loose in a way that spoke of too many men. Choi Sun-woo's cock was not Ailes's size, either. Still, she rode him with a fairly sexy motion, and that was enough to keep it from being a waste. Her face was beautiful, which helped. What truly stood out, though, were her mouth and her hands. Those, at least, held their own against any of the others.
Squelch. Squelch.
"Haaah... it feels so good!!"
"Hey. Don't just enjoy yourself. Tighten that pussy more."
At Dong-hyun's words, Se-bin sat up straight and seemed to clench down around him.
"Nngh... okay... haah... how is it?"
"Much better than before."
She was actually putting some real effort into it, and the difference was decent. The problem was that tensing her ass stole the life from her hips. Se-bin was clearly going to need a lot more training.
Left with no other choice, Dong-hyun pushed her onto her back and took over, driving into her with his own waist.
"Tighter!!"
"Nngh... yesh!! Aah!"
As he thrust, he cracked an open palm across Se-bin's heavy breasts.
Smack. Smack.
Her tits bounced and danced from side to side, and every scream that tore out of her made her pussy clamp down that much harder.
"Not bad."
He kept slapping her chest while he fucked her. Once the tightness settled into something worthwhile, Dong-hyun came inside her.
"Suck it."
"Haa... haa... yesh..."
Se-bin lay there catching her breath, apparently satisfied with the way he had used her, then pushed herself up and took his cock into her mouth. Her fellatio really was quite good. He came down her throat a second time.
"Come here. Present your pussy."
Se-bin stepped in front of him and offered herself. He fitted the vibrator and the chastity belt back into place.
"Give me your phone. You too, Kim Tae-yang."
Both of them handed their phones over. Dong-hyun installed a hacking app on each one.
"I can record, tap, track your location, and pull your call logs off these now, so don't try anything stupid. Got it?"
"Understood."
The siblings swallowed even that absurd demand without a fight.
"Ah. And Kim Tae-yang — you've been especially annoying, so you're at the very bottom of the hierarchy."
"What?"
Kim Tae-yang had been the ringleader behind Choi Sun-woo's bullying, after all. Dong-hyun installed the chastity-belt switch app from his own phone onto Se-bin's.
"Se-bin. If Kim Tae-yang doesn't listen to you, use this to discipline him."
"Yes! I'll do that."
The idea of being allowed to train her own older brother seemed to interest her.
"And take this with you. Develop his ass a little while you're at it."
"What... is this?"
"A dildo with a prostate-massage function. You stick it in a guy's ass."
Tae-yang's body shuddered as he overheard them. He still could not resist.
"This one's for your exclusive use. Develop him properly. Understood?"
Giving Se-bin the power — and making her the one who kept Kim Tae-yang in line — had been the point all along.
"Ohh... understood. Thank you, Master."
Se-bin looked thoroughly pleased with the order. Then she opened the app on her phone.
"Nnnngh... ghhhk..."
Kim Tae-yang clutched at his chastity belt and crumpled forward.
"S-stop... nngh..."
"Hmm? What are you supposed to call me?"
"You... crazy bitch!! I said stop... AAAAGH!!"
"Hmph. As I thought — this animal needs training. Crawl over here and lick my feet."
"Ghhhhk..."
Kim Tae-yang dragged himself across the floor, barely holding the pain down, and licked Se-bin's feet. His face was already a wreck of tears and snot.
"From now on, you call me Queen. Got it?"
"Yes... Queen... please... turn it off... AAAAGH..."
Once she had watched him fold, Kim Se-bin switched it off.
"Master. I'll thoroughly train this disobedient mutt."
"Good. I'll leave him to you."
Se-bin looked more than ready to collect on what she was owed — payback, in full, for being overpowered and forced over the edge against her will. The two of them bowed to Dong-hyun and left his house.
Days slipped by in fits of training Tae-yang and Se-bin. Then, one evening, a message arrived from Han Su-yeon — a text on Sun-woo's phone, landing right in the middle of Dong-hyun's long, unfinished question of how to make her submit.
Unlike Kim Tae-yang and Kim Se-bin, Han Su-yeon was not someone Dong-hyun believed he could simply overpower. He had been picking up martial arts from Sirian in scraps of spare time, but not nearly enough to close the gap. If he was going to make Su-yeon submit, he needed real skill — and the only way to measure hers was to stand in front of her and find out.
So he went. Whatever happened, he would collide with her first and sort out the rest after. He arrived at the gym at the hour she had named. Sun-woo had known her since they were children; the location was already sitting in his borrowed memories. He followed those memories straight to the building.
The sign over the gym was dark. He walked down into the basement. The door turned freely in his hand — unlocked. The floor inside was empty except for the octagon. Han Su-yeon was alone in the cage, moving. Shadowboxing, maybe. Warming up. She stopped the moment she saw him come in.
"Come in."
Su-yeon crooked a finger at him. Dong-hyun opened the cage and stepped through.
"You've been looking pretty comfortable lately. Looks like you've completely swallowed up Kim Tae-yang and Kim Se-bin."
"Is that any of your business?"
Han Su-yeon smirked.
"Ah... it's not, really. But their company is still my sponsor. I think you've crossed the line a bit, so I figured I'd step in and mediate."
A flicker of anger cut through Dong-hyun.
"Unbelievable. You sat there doing nothing when they crossed the line — and now you show up?"
"That's... because you were a nobody. Kim Tae-yang and Kim Se-bin are different. They're chaebol heirs. Stay on good terms with people like that and it pays off someday."
In Sun-woo's memories, Han Su-yeon had been straightforward — the kind of woman who did not pick on anyone weaker than herself. He had not realized that, somewhere he had not been looking, she had turned this selfish, this opportunistic.
"Ha. So that's your true nature. Thanks. Now I feel like doing this properly too."
Dong-hyun rolled his shoulders out inside the cage and stripped off his shirt. A week of work had left its mark — faint lines of muscle had begun to cut across Choi Sun-woo's body.
"No matter how much you struggle, you think you can take me? Just tell them you'll leave them alone from now on and I won't push this any further. How about it? Want to back down while you still can?"
Su-yeon had no idea. Completing the quest meant making her submit either way. If a fight was inevitable, now — with no one around to interfere — was the perfect time.
The two of them faced each other inside the cage. No mouthguard. No gloves. No protection of any kind. A real fight.
Su-yeon peeled off her hoodie and sweatpants. The sleek, trained lines of her body came into the light — but Dong-hyun's eyes were not taking any of that in. The power standing across from him was too unusual for that.
He stripped off his own pants and stood in front of her in nothing but his underwear. Something flickered through Han Su-yeon's eyes at the sight of him, then vanished.
Dong-hyun moved first, bursting in and throwing a punch. The jabs were sharp enough, but Han Su-yeon barely tilted her head to slip them, then used her sense of distance to fade back out of range of the follow-up. He chased her footwork, throwing punch after punch, but the gap in skill was simply too wide.
She was slipping left and right with almost leisurely ease — and then, in a single instant, she timed his punch and fired a counter. Her fist cracked into his jaw. Dong-hyun went rolling across the octagon floor.
He had been attacking on such honest, readable timing that she had picked it up in a heartbeat and punished him for it. But that was exactly what Dong-hyun had been waiting for.
Pretending to go down, he snared Han Su-yeon's ankle as he fell. Then, through the quest window he had already opened, he transferred.
The world shifted. Dong-hyun found Sirian in a rush and dragged her, half-running, to the training grounds.
"Sirian. Teach me grappling."
