Morning After the Slave: Breaking Seoyeoun
The next morning, Seonwoo dragged his heavy, listless body out of bed. Last night's passionate romp with Yuri felt like a distant dream.
Out of habit, Seonwoo grabbed his smartphone and opened his banking app. The moment he checked his balance, he snapped wide awake.
Just yesterday, he'd had over 35 million won. In a single night, 30 million had vanished into thin air. The points he'd poured into his stamina stat were now hitting him like a ton of bricks.
Fuck... that was some insane shit.
No matter how much his lust had clouded his brain, he'd burned 30 million won on one night of fun.
A wave of regret washed over him briefly. But then he recalled Yuri's teary eyes, her vulgar ecstasy as he choked her, and the godlike 10-Min Preview skill. The regret melted away like snow in the sun.
No, this was the best investment ever.
For 30 million won, he'd fully breached one woman's defenses and gained a near-divine skill. Seonwoo smirked in satisfaction as he settled in front of his computer.
"What's lost can be earned back."
Seonwoo logged into the Bitup Exchange. A newfound confidence surged through his veins, unlike yesterday.
Time to test the 10-Min Preview.
Like before, he scanned the list of volatile altcoins and picked one with the highest trading volume. He activated the skill.
Asia Dragon Coin: Replaying the next 10 minutes.
The scene unfolding before his eyes was on another level from yesterday. It wasn't just a simple graph fluctuating up and down.
The full 10 minutes played out: order book, trade history, bid-ask volumes—every detail captured in vivid video. Seonwoo fast-forwarded, noting the absolute low and high points.
Lowest at 3:17, peak at 8:42. Perfect.
Precisely at 3:17, he dumped his remaining 5 million won into the buy. At 8:42, he set a sell order. Ten minutes later, his account showed exactly 7.2 million won. He'd made 2.2 million in just 10 minutes.
"Kuuh...!"
Seonwoo let out an involuntary groan of ecstasy. The thrill of watching money multiply was a different beast from the orgasm of sex—it was pure, intoxicating exhilaration. Without pause, he eyed his next target.
The 10-Min Preview was straight-up cheating. No more relying solely on the outcome 10 minutes from now. He entered at the perfect moment and exited at the perfect moment.
He sprinkled in some leverage here and there. His assets snowballed exponentially.
By lunchtime, his balance had surpassed 30 million won again. He'd recouped the night's loss in half a day. Seonwoo kept rolling, hitting 50 million before sunset.
"So this is what making money feels like...?"
Seonwoo set a new goal.
10 billion. Let's aim for 10 billion first.
As he dove back into trading, his phone buzzed with a short vibration. A text from an unknown number.
Lee Seoyeoun. The o피 girl he'd met a few days ago. Her provocative face and voluptuous breasts flashed in his mind. With money, stamina, and his new power in hand, arrogance swelled in Seonwoo's chest.
The billions he'd just been fantasizing about felt within his grasp.
Money I can make no matter what? Why not? His self-esteem soared sky-high.
Without hesitation, Seonwoo replied.
Seonwoo stopped by the bank, withdrew 5 million won in cash, stuffed the thick wad into his pocket, and took a taxi to Lee Seoyeoun's officetel.
The Gangnam scenery blurring past the window felt different now. He wasn't the timid guy from days ago.
At the officetel, Seoyeoun opened the door. She wore only a sheer black slip that left little to the imagination.
"Whoa, you really came right away?"
She was surprised but couldn't hide her delight.
"It's my day off today. I just missed you, oppa, so I texted."
She wrapped her arms around his neck, whispering seductively. It was a blatant offer for free sex.
With his ego skyrocketing, Seonwoo found her charity-like proposal deeply insulting.
Irritated, he shoved her aside, strode in, and slammed the wad of cash onto the table with a loud thud.
"Oppa...?"
"I don't do freebies. And today, I'm not your oppa—I'm a customer."
Seonwoo's voice was ice-cold. Her smile vanished from Seoyeoun's face, replaced by bewilderment laced with a subtle thrill.
"If you're a customer... what do you want?"
"Strip."
Seonwoo commanded as he sat on the sofa, legs crossed, though a corner of his mind worried she might refuse.
"Then crawl over here on all fours. Like a dog."
Humiliation flushed Seoyeoun's face. Her pride stung.
"What did you say? Hey, do you even realize what nonsense you're spouting?"
She snapped back in anger, but Seonwoo's arrogant dominance made her body twitch involuntarily. Being treated like an expensive whore by a rich guy twisted something deep in her gut. "So? You hate it?"
Seonwoo smirked slyly, adding softly, "If you hate it, forget it."
She hesitated, then with trembling hands, slipped the straps off her shoulders.
The black fabric pooled on the floor, revealing her lush naked body. With a humiliated expression, she dropped to her knees and crawled to his feet on all fours.

"Good girl."
Seonwoo smiled in satisfaction, yanking her hair to force her head up.
"Hngh...!"
He whispered in her ear.
"From now on, call me Master."
"Y-Yes...? Th-that's..."
Seoyeoun stammered in confusion. Even as a paid companion, her pride rebelled against such a title.
"Hate it?"
Seonwoo gripped her hair harder and shoved his fingers roughly into her pussy.
"Ah! It hurts, it hurts!"
"Answer me. Do you hate it?"
"N-No...!"
"Then say it. 'Master.'"
Tears of humiliation welled up. But her body, already tamed by his touch, leaked slick juices. She had no choice but to submit.
"M-Master..."
It was a mosquito-like whisper.
"Can't hear you. Say it properly, or I'll just finger-fuck you till I cum. No cock for that pussy of yours."
Her body shuddered at his words. She'd called him for a vigorous fuck from a stud, but she actually liked him too.
Finally, she cast aside all restraint and cried out through sobs.
"Master! I'm sorry! Fuck Seoyeoun's pussy, Master!"
"There we go, should've done that from the start."
Seonwoo grinned, thrusting his cock deep into her dripping, stringy-wet pussy in one go.
Her back arched like a bow, but he ignored it and pistoned his hips relentlessly.
The stamina investment paid off massively. Seonwoo felt no fatigue. An hour passed, then two—his cock showed no signs of softening.
He tossed her onto the bed, the sofa, pinned her against the wall—ravaging her in every position. Seoyeoun climaxed repeatedly, nearly passing out, but he gave her no respite.
"Master! Ah! Ah! My pussy's gonna burst! Aang! Please, please cum inside! Fill me with Master's cum!"
"Not yet. If you're a slave, cry more. Beg like the slut you are."
"Urghhh...!! Cum inside, Master! Fill Seoyeoun's pussy with your thick Master cum...!!"
The more she begged, the crueler Seonwoo became. He slung her legs over his shoulders and spat in her face.
"Ptui. Lick that too."
Trembling with humiliation, she stuck out her tongue and lapped it up. She pulled his hand to her mouth, sucking his fingers as she pleaded.
"M-Master... please, I'm sorry... Cum just once... okay? Seed this worthless slut's pussy!"
Her utter submission ignited even greater arousal in Seonwoo.
Now fully a bitch in heat, Seoyeoun begged with tears and drool streaming down her face. Only then did Seonwoo smile in satisfaction and flood her insides with hot semen.
When it was over, Seoyeoun lay sprawled on the bed like she'd fainted. Seonwoo wiped his sweat, dressed, and picked up the cash stack from the table. He tossed only 500,000 won beside her head.
"That's your worth right now, got it? From now on, think about how to please me more so I pay you better."
"N-Nggh... Y-Yes... M-Master... Th-Thank you..."
Seonwoo sat in a chair, watching her struggle to retract her lolling tongue as she answered. Satisfaction gleamed in his eyes alongside cold dominance.
The power of money. The ecstasy of dominating a woman.
Seonwoo was just beginning to taste it. A boiling desire rose to make more women kneel at his feet.
He'd never dreamed he had such a sadistic streak. He'd thought he just liked soft touches.
But no. The saying goes that true nature emerges at the cliff's edge, but I disagree.
Human nature reveals itself only when there's enough leeway to indulge.
This is just the beginning.
But getting devoured by desire would make him a mere beast. Women he truly liked deserved proper care...
Unfortunately, Lee Seoyeoun simply didn't measure up to Yoo Sori, whom he'd just broken in.
Seonwoo left the officetel. His story had only just taken its first step.
