Subjugating the Bully Girl (10)
"Hngh... nnhhhh!!"
Dong-hyun had Su-yeon pinned so thoroughly she couldn't so much as twitch, his face buried between her thighs as he sucked at her. Every flick of his tongue against her sent another moan spilling from her lips. His hands gently kneaded her breasts, massaging them with a slow, deliberate pressure, while his tongue pushed deeper still, working its way inside her.
He licked slowly around her inner lips, then slipped his tongue through the pink cleft — and felt the wetness surge up from within.
"Feel good?"
"D-don't say such ridiculous things..."
Su-yeon dismissed him out of hand, but she knew perfectly well what her own body was doing.
She had carried a quiet affection for Sun-woo since high school — the diligent, brilliant boy who never seemed to notice anything but his textbooks. He had never given her a second glance, and Su-yeon's own nature had never allowed her to make the first move.
When they ended up at the same university, the joy of it had been almost overwhelming. But then Sun-woo became prey for Kim Tae-yang's clique, and after a great deal of agonizing, Su-yeon chose her own success over any feelings she might have had. She left him to fend for himself. Later she heard he had suffered something truly shocking, and the guilt had been real — but she still pretended not to know.
Then Sun-woo changed. He crushed Kim Tae-yang. And a selfish fear crept in: that her failure to help him back then might become an obstacle on her own path to success. So she summoned him to the gym. She had never once imagined she would lose. And now she had ended up like this.
Shame and humiliation warred with a strange, illicit thrill — the boy who had never once looked her way was now devouring her body. Her words came out sharp and dismissive, but her body was answering him honestly. In moments like these, the body was always the more truthful of the two.
"Is that so? Heh. Then why don't we watch our Su-yeon put on a little fountain show?"
Dong-hyun didn't rise to her protest. He simply lifted his face from between her legs and brought the hand that had been working her breasts down to her sex instead.
His hands had grown thoroughly practiced by now. He knew exactly where to touch, exactly what speed and what pressure would make a woman come apart. He rubbed around her inner lips in slow, friction-heavy strokes — then, in a single motion, slipped inside her. Middle and ring finger together, he dragged them along her inner walls as if scraping them with his palm, pushing in fast and drawing out slower, bearing down on the flesh as he withdrew.
The moment his fingers entered her, her lips were already fluttering in response.
"Hnnnngh!!!! Stop it!!"
A strange sensation bloomed deep inside her, and a shiver ran through her whole body.
W-what is this... it feels so strange...
It was a bewildering feeling — hazy and dizzying, as if she had been submerged underwater, and yet somehow warm, almost comforting. Completely different from what his tongue had done to her. And then something like a core deep inside her felt as though it were about to burst.
"Ah... no... w-what is this!! It feels weird... hyaaaaah...!!!!!"
Under Dong-hyun's hands, she squirted.
It was the first orgasm of Su-yeon's life. Her nipples stood rigid. Every hair on her body seemed to stand on end. It felt as though every muscle, every nerve, every last cell was firing at once.
"Haa... haa... ha... ah...???"
She was still riding the aftershocks, trying to surface from those depths, when a massive wave came crashing down all over again. He had already wrung one climax out of her. Now it was her clitoris's turn.
Su-yeon's clit had been shyly hidden beneath its hood — but in the throes of climax it had peeked out, and that was where Dong-hyun's two fingers found it, rubbing it between them.
"Hggggh!!!"
Already hypersensitive from what she had just been through, Su-yeon couldn't hold a single coherent thought against the fresh onslaught.
"Ehk... nhh.... nngggh!!"
Nothing resembling words came out of her anymore — only moans, one after another. Dong-hyun's hand moved faster and faster, and her clit swelled, flushing darker as the blood rushed to it. He kept it pinched between his fingers and worked it without mercy.
"Aaaah nngiiiiih!!!!!!!!"
Her toes curled. Her muscles seized as if they were crumpling in on themselves. She squirted again — and then she fainted dead away.
"Nnhhh... mm...?"
Su-yeon came to with the feeling of having been pulled from the sweetest sleep. Then her body refused to move, as if she were trapped in sleep paralysis. When her mind finally cleared, she found herself bound to a piece of exercise equipment inside the gym.

For a moment she couldn't make sense of any of it — and then it hit her. She had been utterly, humiliatingly defeated by Choi Sun-woo. And she remembered everything that had come after. His fingers. Losing her mind. Squirting like that, then fainting in the most disgraceful way imaginable. Her face went scarlet.
"Awake?"
The voice came from behind her. She whipped her head around and found Dong-hyun standing there, smiling as he looked at her.
"That was quite the performance. Did my hands feel that good?"
Su-yeon had no answer for the teasing. She had come so hard she'd passed out. There was nothing left to say.
"Though I suppose I already know. You came too hard to even talk back. I took a direct hit from that fountain of yours, actually — I just got out of the shower."
Now that she looked, he wasn't wearing so much as a towel. Su-yeon jerked her head away.
"You're going to be sucking and licking it later anyway. What's the point of looking away?"
"You're insane... you think I'm going to do that?"
"Hmm... it's nine o'clock now. I'd say in a generous four hours, you'll be begging me to let you."
Unlike Adrian from the tutorial, he didn't expect Su-yeon's willpower to hold out that long. She was a D-rank difficulty — an easy mark, honestly. Kim Tae-yang and Kim Se-bin had folded without much of a fight, and he didn't see Han Su-yeon lasting much longer either. Her body was more responsive than he'd anticipated. This wasn't going to be difficult.
Dong-hyun stepped around in front of her, where she hung bound and completely unable to move. He had come prepared for exactly this, and his bag was stocked with an assortment of toys. He started by attaching a rotor to each of her nipples, then another to her clitoris.
"What are you doing..."
There was a thread of unease in Su-yeon's voice, but Dong-hyun didn't bother answering. He simply kept working.
He had brought five rotors in total. One on each nipple, one on her clit — that left two. He pushed one of them inside her.
"Nnhh..."
A small moan slipped out of her at the sensation of the cold toy sliding into her. Dong-hyun took the last remaining rotor and walked around behind her.
A wet, squeezing sound came from her back.
Then something slick and cold pressed against her anus.
"Aah!! W-what is that!! Hhk!! Take it out... don't put that in!!!"
It began pushing into her.
"Nngiiih!!!"
The alien sensation made every muscle in her body go taut. And then, suddenly, the world went dark. Dong-hyun had slipped a blindfold over her eyes.
He had used the same trick on Adrian. Cut off someone's sight and every other sense comes roaring to life — and the fear doubles with it.
"I haven't eaten yet, so I'm going to go grab some food. I'll be back in about an hour. Take your time and think it over."
He opened the app on his phone and flipped the switch.
A low, relentless buzz filled the air as all five rotors roared to life at once. Vibration bloomed across every sensitive place on her body, and Su-yeon jerked against her restraints. The ones on her chest were almost bearable. The one on her clit was enough to drive her insane. But the real core of it was the pair inside her — vagina and anus, positioned so perfectly that they knocked against each other as they trembled, amplifying every pulse.
"Nnhhh... s-stop... hyaaah..."
"I'll be back."
She heard his footsteps receding, unhurried. A moment later the door opened, then shut.
"N-no... please..."
Su-yeon called after him in a rush, but no answer came. A shout tore out of her.
"Help me!! Somebody help!!"
She clamped her mouth shut almost immediately. The last thing she wanted was for someone to walk in and see her like this. All she could do was grit her teeth and endure.
"Y-you son of a bitch... you think I can't last?"
She swore to herself she would hold out if it killed her.
Meanwhile, Dong-hyun — who had claimed he was going to eat — had never left the gym at all. He had opened the door and simply closed it again. Then he slipped off his shoes so he wouldn't make a sound, walked back, and sat down in front of her to watch.
A woman with a taut, athletic body, a beautiful face, and equally beautiful breasts, stripped naked and bound, moaning helplessly — it was a magnificent sight.
For all her vow to endure, Su-yeon lasted ten minutes before she started writhing.
"Haaang... nnhhhh..."
The fluid spilling from her had already run down and begun to pool on the floor.
"Ah... no... I'm gonna come... nnhhhhh!!!! Haaang!!"
She hit her first climax in just ten minutes, squirting hard. But Su-yeon, blindfolded, had no idea how much time had actually passed. It felt as though she had been locked inside an eternity.
