A Sinful Man

Chapter 11

Why the fuck is that damn bitch acting up again?

Park Ha-rin lowered the bamboo sword she'd been swinging and approached Hayase with a smile. Without warning, she caught Hayase's shoulder in her pale left hand and whispered something rapidly.

She spoke too quietly for me to hear.

Hayase's neatly arched brows rose. Disbelief flickered across her face as she stared at Ha-rin.

What...?

A moment later, something fierce kindled in Hayase's eyes. The determination in her gaze startled even me.

Ha-rin didn't so much as blink. She met that defiance head-on.

Dangerous.

Alarmed by a danger I couldn't put into words, I hurried between them.

"S-Sis, w-what are you doing here? You're making Instructor Hayase uncomfortable."

Ha-rin turned toward me, her expression blank.

"...Why? Is that what you're asking? Are you worried about some other woman right now?"

"...."

Her gaze swept over me, and her face darkened.

I couldn't explain why that look frightened me so much. It just did.

I forced a smile and began massaging her shoulders.

"S-Sis, I think we're drawing attention. Let's g-go back to our seats. Please...?"

"..."

Ha-rin gave me another searching look, then fixed her attention on my eyes.

"..."

What was she trying to find there? Before I could guess, her lips curved into a languid smile.

"Alright, then. My Si-hyun, you knead my shoulders so well. Will you knead them some more? I've got such big breasts, so my shoulders get really stiff, you know."

"Y-yeah. Y-yeah."

...Acting fucking crazy, aren't you. I know full well that even if you lugged around a ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠pair of tits the size of your head, you wouldn't get sore.

Desperate not to provoke her again, I followed her back to our seats.

Fortunately, the attention seemed to have lifted her mood. She looked at her bamboo sword and began humming to herself.

A moment later, she raised the sword with an expressionless face. The other new students watched her abrupt change of mood uneasily.

No one dared comment. There was something in Ha-rin's cutting gaze that silenced them all.

Hayase turned to look at her. Despite her defiant stare, her fist trembled.

Everyone seemed to sense the same danger. Ha-rin's smile was unpredictable enough to keep the entire room quiet.

#

Ten days had passed since the Park siblings enrolled at the dojo.

"...Haa."

For Hayase, those ten days had been an ordeal of mounting anxiety. Ever since she'd glimpsed the unsettling side of Park Ha-rin, she hadn't been able to shake the memory.

What a terrifying woman...

She knew she couldn't keep living in fear, yet her unease refused to fade.

"Hayase. You haven't been able to concentrate at all lately. Is there some worry on your mind?"

Eventually, even her father, Han Hyeok-do, noticed how distracted she'd become.

Hayase met his concerned gaze with a strained smile, ashamed of worrying him.

"...No, it's nothing. I guess I just have a lot on my mind. I'm sorry, Father."

Han Hyeok-do set a bowl of soup on the dinner table, nodded, then looked at her seriously.

"Is it perhaps because of that pretty boy, Park Si-hyun?"

"...Huh?"

"...Just kidding. It's probably because of that monstrous woman, Park Ha-rin."

"!"

Hayase's surprise vanished almost at once. She fell silent, and her father nodded as though that confirmed his suspicion.

"I've questioned my own eyes more than once. At first I thought she had muscles trained only for appearance, but no human body should move that way. Muscles simply aren't that elastic or flexible."

At a glance, Ha-rin's physique looked almost ornamental—beautiful, but hardly intimidating.

Yet when she lifted a bamboo or wooden sword, her muscles showed no strain at all. She handled the weapons as though they weighed nothing.

Hyeok-do had watched her closely, unable to believe what he saw. He'd even put the new trainees through punishing drills to test her.

But even as everyone gasped for breath and collapsed from exhaustion, Park Ha-rin's breathing did not waver, not even a little. No, she was pretending to pant and struggle for breath, just like the others.

No cramps. No frantic, exhausted stare. Not even sweat. She lacked every sign of the fatigue that left the others struggling to stand.

'Any ordinary person would have found that training grueling.'

Ha-rin hadn't struggled once. She'd merely pretended to be exhausted alongside the others. When her eyes met Hyeok-do's, however, the strained expression disappeared, replaced by an easy smile.

That was when he'd understood: her body exceeded human limits. Worse, something about the way her mind worked seemed equally unnatural.

"...So I tried to have a private talk with her, intending to recommend some mental discipline, but..."

─If my younger brother were to misunderstand the relationship between me and the dojo master, that would be a serious problem. Please keep to the point, and finish within fifteen seconds, will you?

The instant he'd met that dangerous gaze, Hyeok-do had understood it instinctively. For a fleeting moment, she'd let her true nature show.

He'd glimpsed someone calculating and vicious, with a darkness at her core that he could scarcely comprehend.

Never in his life had his survival instincts sounded so loud an alarm.

"...Stay away from that family. But to drive them out... I'd say the aftermath would be too much to bear."

Hyeok-do clenched his fist, trying to master the lingering fear. He'd felt like a frog frozen before a snake, unable to move while its fangs drew closer.

Every instinct in his body had warned him to stay alive by staying away.

Getting close to her promised nothing good. Yet openly rejecting her might be worse. He could only keep his distance and hope she'd lose interest.

Noticing how grim their conversation had become, Hyeok-do forced himself into a cheerier tone.

"Hahaha. Hayase. Your cooking these days is so much better than your mother's was in her younger days. At this rate, your mother, who's off so far away, would be pleased."

He spoke with a wistful smile, as though recalling the old days. Hayase answered with a faint one of her own.

Her father was trying to lighten the oppressive mood, and she was grateful for it.

Still, she laid down her chopsticks, straightened her back, and answered crisply.

Anyone overhearing them might think her mother had died. She was perfectly well, though—just staying with her relatives in Japan for a while.

"Dad. When Mom comes back, are you going to tell on me?"

"I trust you, Hayase."

Hayase covered her mouth and laughed softly.

"Okay. Got it, Dad. I'll keep this our little secret, just between the two of us."

"Hayase...! I love you! Every one of those bastards who tries to take my daughter away will be dealt with by this father!"

He was the sort of father who would sacrifice anything for his family.

Yet today, Hayase had seen that even the father she'd always thought so formidable could be frightened.

'Do not get involved with them....'

Back in her room, Hayase lay on her bed, her thoughts strangely foggy.

Remembering Ha-rin's gaze still made her tremble. Paradoxically, though, something stronger than fear was growing inside her.

"Haa..."

Park Si-hyun.

From the moment they'd met, he'd captured not only her attention, but her heart and every waking thought.

The more she thought of him, the less Ha-rin's threat seemed to matter. Another, more urgent feeling crowded out her fear.

She knew she shouldn't let herself think this way.

She'd never allowed anyone to sway her before. She'd lived with strict self-discipline.

But.

"Haa... he was so cute..."

Hayase had changed.

From her cute pillow, she pulled out a kendo uniform sealed in a pack.

—Uh... by any chance, do kendo uniforms get lost here often, or something like that?

Park Si-hyun, who had come to her with a bewildered look on his face. Just recalling his voice and his face made her smile.

Pressing her face into the kendo uniform that bore his scent, she unfastened her skirt and slipped her hand inside.

Her fingertips found her panties already soaked through, and they squelched.

"Nnh."

Between his scent and his sweat, her body had already heated up like a female in heat. As though it had been made to fit him from the start, it responded intensely.

"Mmhh..."

Stifling her moans with the kendo uniform, she stirred the outside of her panties without pause. The more she did, the more his image refused to leave her head, and together with his scent, it felt ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠as though her ovulation was drawing near.

"Ahh, hnn..."

Until she turned twenty, she had never once felt this way toward a man. It felt as though something in her body had broken.

Whenever she saw Park Si-hyun, an intense craving surged up from ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠her womb, unbearable, and without realizing it, she ended up tracking him with her gaze. Each time, she was reduced to a female who, her panties soaked through, could do nothing but secretly masturbate.

"Nnnh, y-you... you're too handsome...!"

She knew this wasn't normal. But there was a woman even less normal than her, guarding Park Si-hyun's side.

"Ah...♡"

If, when she had first met Park Si-hyun, she had deliberately fallen and touched his body, or if she had guided him to the changing room and, without hesitation, fetched at least his underwear...

"Hnnh!"

Pushing her panties aside, she touched her wet clit. From her narrow vaginal opening, steam rose as it throbbed open and shut.

"Haaah!?"

Unable to hold back, she pushed her middle finger inside, and a moan escaped as her head turned to the side. Thinking her voice was too loud, she hastily bit down on the blanket and kept moving her hand.

Without stopping, panting, she stimulated her vaginal folds and her hymen. Park Si-hyun. Park Si-hyun. Park Si-hyun. Her body and her heart wanted all of him.

I want to burst my hymen with his cock.

A face and a build she felt she would never tire of seeing for the rest of her life, as if made to fit her exactly...

It was like sinking into a swamp she could never climb out of. But it didn't matter. As long as she could have him...

"Hup?!"

As her hand grew increasingly frantic, her womb throbbed and her hips lifted right off the bed. Her snow-white thighs trembled violently, and her vaginal opening twitched shallowly.

Arching her hips like a shameless slut, with only one finger inside her, love juices spilled from her entrance several times. Silently, Hayase reached her climax, and her hips dropped back onto the bed.

"Haa... haa..."

This would keep her fine for now.

From her pink pussy, its pale lips folded together, clear love juice trickled out in a steady stream. She had soiled the bed again. Even so, the fundamental deficiency had not been resolved. Hayase knew it too.

"...I... want to have him."

She'd watched him for ten days, long enough to see how Ha-rin kept him frightened and subdued.

If Hayase could stand beside him, she would make him happy. She would never let that smile disappear.

"..."

Her fist tightened without her noticing.

I have to make him happy.

A determination she'd never felt before filled her thoughts until there was room for nothing else.

That was why she finally spoke.

"Ms. Ha-rin. Would you care to spar with me?"

Hayase challenged Park Ha-rin to a sparring match.

Ha-rin answered with a brilliant smile.

"I was wondering when you'd finally say that."

Murderous intent lurked behind that smile. Hayase raised her sword, her expression resolute.

She would no longer watch in silence. What she'd felt beneath her terror when she met Ha-rin's eyes was anger—and a refusal to submit.

Before the watching students, the two women raised their swords.

Their match was about ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠to begin.
