The First Training
With her consent thus secured, the man opened his mouth in a deeply satisfied voice.
"Then shall we start by changing how you address me?"
"A-Address?"
"That's right. Though it's just a verbal contract, we are undeniably in a master-slave relationship now."
Saying this, the man grasped Minseo's chin, forcing her to look straight up at him.
"...Well then, as a test, why don't you try calling me Master?"
Though she inwardly thought it was a perverse kink, Minseo soon put on a resigned expression and replied.
"M-Master...."
Her mouth formed the word Master, but her face showed none of the deference of a slave gazing up at her owner.
Still, the man seemed satisfied just to hear it, letting out a small chuckle as he spoke.
"Heh heh, not bad at all."
"...."
"Now, as a reward, I'll give you a little treat."
With those words, he ostentatiously shook the rotor in his hand from side to side.
"Y-You're really going to make me a pro player, right?"
"Of course. If you ever think I'm lying, feel free to curse me out anytime."
"...."
At his words, Minseo's face clouded with hesitation for a moment.
"...Okay."
In the end, she steeled herself with a determined nod.
Without delay, he reached out and stripped off her pants.
"Quite soaked with sweat."
"Eek...."
The instant his hand touched her bare skin, she involuntarily grimaced in disgust.
Her mind understood this was part of the contract, but her heart still rebelled against it.
Is it really okay for me to do this?
No matter how much it was for her dream, was it right to give her body to some unknown man?
It was no different from selling herself.
But that doubt lasted only a moment. Minseo hardened her resolve.
Even if she refused his offer here, their relationship was utterly one-sided.
Above all, he had the power to drag her here by force.
Her only resistance was to hide her pleasure as much as possible and hurl insults at him.
...No. This is the right thing. For my dream, I can handle this much.... There's nowhere left to retreat. This might be my last chance!
Minseo soothed her still-rebellious heart and convinced herself.
"Looks like you've been working out."
"Y-Yes...."
"You like volleyball?"
As he peppered her with casual questions, he stripped off her pants and panties.
Minseo knew what he was doing but obediently followed his touch as she answered.
"I like it."
"When did you start playing volleyball?"
"In... third grade of elementary school.... But I got serious about it when I entered middle school."
"I see. You've loved it since you were little, huh."
He let out a short chuckle, then brought the rotor in his hand toward her pussy.
"A-Are you going to put it in?"
"No, not right away."
With that, he lightly pressed the rotor's rounded tip against her entrance.
"Ha-eut!"
Just the touch of the rotor against her pussy sent waves of pleasure far beyond her imagination.
What... what is this?
Was there some special device on it? Minseo stared at the rotor against her in disbelief.
But the purple rotor had no such gimmicks. It was just an ordinary one, like any you could buy anywhere.
"Now, let's enjoy this nice and slow."
His voice brimmed with amusement as he flicked the switch.
"Hya-eut! A, ahhhgh!"
The moment the rotor began vibrating, a scream-like moan escaped Minseo's lips.
"...W-Wait.... Hiiik! T-Too strong.... Hnngh!!"
"Too strong? This is the lowest setting right now. The minimum."
"Th-That's! Hya-eut!"
As he pressed it closer, Minseo's back arched sharply.
She's feeling it well.
"You're quite sensitive."
Saying this, he pulled the rotor away, and only then did Minseo gasp for breath, curling her body as much as she could.
Of course, with her hands and legs bound to the chair, there were clear limits to how much she could shrink.
"...How often do you masturbate normally?"
Suddenly, he gently stroked her thigh as he asked.
Minseo shrugged faintly in response.
"O-Once or twice a week...."
"What about sex with your boyfriend?"
"N-None."
"You don't have sex? Or no boyfriend?"
Suddenly, his finger brushed her pussy.
"Hngh!"
Minseo shuddered lightly with a moan.
A smile crept unbidden to her lips.
Unlike the rotor, his finger moved just right—gentle, soothing strokes that eased her like loosening tense muscles after intense exercise.
"Will you answer?"
At his urging, Minseo looked down at him and replied.
"No boyfriend."
"You broke up?"
"Yes...."
"When?"
"In college.... That's when we broke up."
"No one since?"
"Yes.... No time to date."
Her answers clearly pleased him; he burst into loud laughter.
"Perfect. I knew choosing Kim Minseo was the right call."
With that, he began easing the rotor into her pussy bit by bit.
"Hah, ngh!"
Though only slightly thicker than a thumb, it felt overwhelming to Minseo; she panted, her back stiffening rigidly.
"As expected, unused for so long—tight as can be."
Admiring it nonstop, he carefully pushed the rotor deeper.
Though her pussy was as narrow as a virgin's, she wasn't actually one, so it soon yielded, allowing him to insert it fully.
"Hooah, ah.... Aaah."
"It might hurt now, but you'll feel good soon enough."
He flicked the switch.
"Hyaangh!! A, aaang! Ah, wait.... Hnngh!!"
Not even that strong a vibration, but amplified by the Training Room's effects, the pleasure hit Minseo like nothing she'd imagined.
And it had been years since anything had stimulated her inside.
Caught off guard by the intense bliss, she wailed in confusion.
"...Hiiik! A, aaang! No! If you keep—... Aaah, I'll die! Ngh!"
As the stimulation continued, her love juices began trickling from within.
"Starting to feel it, huh."
He chuckled, scooping up the fluids with his finger.
At his touch, she arched her back again, her lips parting slackly.
"Hah, aaang! Ah, if you touch—... Hooaht!"
"Accept the pleasure. You'll get used to it soon."
"Hik! A, aaaah! No!"
Another alert.
"P-Please... stop now...."
"Still a ways to go."
"B-But the sound... it's rung twice already...!"
At her words, the man stiffened briefly before chuckling again.
"You heard it from Yu Seoyeon? Heh heh, but what can you do? This sound doesn't mean anything."
"N-No way...!"
Hearing that made her vision go dark.
She wanted to surrender to the pleasure, shake her hips lewdly, and beg him to turn it up.
Just let go... no more thinking....
But she snapped herself back.
This was a contract, but there was no guarantee he'd fulfill her dream.
Right—it was a test.
If she submitted here, she'd lose her soul; if she resisted, her dream would come true.
With that thought, she steadied her mind.
"Whatever. It's a bit early to end, but we've raised your Shame decently... and I'm happy to learn more about you, Kim Minseo."
Suddenly, he stood, pulling the rotor from her pussy.
"Haek!"
As it slid out, a strange emptiness mingled with intense stimulation, pounding her brain.
Aaah.... What the hell.
An unknown, overwhelming pleasure dominated her body.
But oblivious to her turmoil, he casually pulled out his smartphone.
"Well then, I wish for Kim Minseo's dream to come true."
With those words, the space before her warped—whoosh!—like mud being stirred.
"Ah!"
Moments later, reality filled her vision.
I'm back....
Finding herself on the court, Minseo collapsed right there.
"Sunbae!"
A few startled juniors rushed over at her sudden drop.
"I'm fine," she said, standing again and quickly checking herself.
It still tingles....
The subtle stimulation below confirmed what had just happened.
"Haa."
Exhaling sharply, she glanced around before hurrying to the bathroom, claiming she needed to pee.
Inside a stall, she dropped her pants and checked below.
"Ah...."
Sure enough, her panties were soaked.
She carefully pulled them down and looked at her pussy.
No....
Though she told herself no, her hand moved toward it anyway.
Leaning against the partition, she began rubbing her pussy with her fingers.
"Hah, ngh! Eut!"
Squelching wet sounds echoed through the bathroom.
Pathetic moans slipped past her tightly pressed lips.
It all felt so obscene; her cheeks burned red.
I have to stop....
Too late—she tried halting, but her hand moved like an independent beast, relentlessly tormenting her with sticky sounds.
Each time, she gasped and twitched.
"Hngh!"
Finally climaxing, she hunched her shoulders, trembling violently before slumping onto the toilet.
Me.... What the hell am I....
Post-orgasm self-loathing crushed her.
A momentary impulse, sure—but in the gym where her juniors practiced? Masturbating secretly in the bathroom like some perverted senior!
...It's all that guy's fault!
She tried blaming him, but the guilt lingered.
After sobbing quietly on the toilet for a while, she realized too much time had passed and stood.
Washing her hands thoroughly, she exited.
"Minseo!"
Suddenly, a voice called from afar.
Turning, she saw the coach standing there.
"Coach?"
"Where the hell were you?"
"B-Bathroom...."
Answering, memories of moments ago made her stutter unwittingly.
But the coach didn't notice—or care—launching into an excited spiel.
"Never mind that— you're up next!"
"W-Where?"
"Against GS Caltex!"
The coach shouted, gripping her hand tightly with a thrilled grin.
