The Concubine's Oath
You did well. You won't kill anyone. You had no choice—it was the threats. Just play along a little longer. There's no one here but the two of you. Just think about how good it feels.
Drunk on those honeyed words, Seo A-ra's pin had been pulled.
As if trying to wash away the sorrow and grief stacked inside her layer upon layer, she chased pleasure all the more greedily, her hips rolling without rest.
Squelch, squelch, squelch, squelch—♥
"Nnnghhaaaaah...♥"
Seo A-ra squeezed her eyes shut and rode it out. Her hips never stopped. Every time the ridge of that glans scraped along her inner walls, every time her womb took a blow from the head of that cock, she thought she might lose her mind. She crushed Cheon Hwa-yeon's head against her chest in a fierce embrace and came again.
"Nngh... nnnnnn...♥"
A moan like an animal's wrenched its way, heavy and raw, through her rose-pink lips. Cheon Hwa-yeon let out a sweet little sound of her own and moved her hands.

She filled her palms with Seo A-ra's ass—round and ample as a full moon—and asked, almost gently,
"Does it feel good, Miss Ara?"
Seo A-ra had forgotten she was even holding Cheon Hwa-yeon's head to her chest. She shook her head wildly, her slender chin scraping roughly through Cheon Hwa-yeon's hair. The gesture all but screamed that she was busy—don't interrupt.
Cheon Hwa-yeon only tightened her grip, as if to soothe her, and posed a different question.
"And who am I, here, Miss Ara?"
"M-my ladyyy..."
"Come now. There's no one here but the two of us, you know."
Seo A-ra hesitated. But the hands locked on her ass were demanding an answer. Fail to say what they wanted, and they would not let go—that much came through with perfect clarity. Desperate to roll her hips again, she finally broke, her voice melting as it left her.
"M...my lady...♥"
"That's it. And what are you, here, Miss Ara?"
"...nothing but...a girl...♥"
"That's right♡ Well done."
Cheon Hwa-yeon eased the pressure in her fingers. The instant that viselike grip on her ass loosened, Seo A-ra resumed her grinding, spilling flushed, heated breaths.
"Now. Let's try that once more."
"Ah... aahh... my ass, there, don't...♥"
"Liar♡ When you're enjoying it this much."
Shlick—♡
"Kyaaaahn♥...!"
Seo A-ra's protests meant nothing. The first joint of Cheon Hwa-yeon's index finger slid back into her anus. That excretory organ of hers, which had long since ceased to function, had been reborn as a toy for pleasure—thanks to Cheon Hwa-yeon.
Squelch... squelch... squ...elch♥
"Nnghnn...♥ I-I hate it... don't...♥ I can't mooove..."
Seo A-ra gave a tiny shake of her head, mumbling. Every roll of her hips meant both holes were being taken at once, and the stimulation was far too much. Especially when that finger inside her ass pressed into the tender inner wall—her knees simply would not hold.
"Fufu... I did push you a little too hard, didn't I. I'll do the moving, then."
"Aaah...♥"
When Seo A-ra truly could not move, Cheon Hwa-yeon gathered her close and shifted their positions. The moment her overworked body was laid out comfortably on the bed, ease bled at once into Seo A-ra's face.
"There. All you have to do is enjoy yourself, Miss Ara. Hands above your head, please. And spread your legs nice and easy."

At Cheon Hwa-yeon's light gesture, Seo A-ra's limbs sprawled across the bed. The posture left her armpits and groin utterly exposed, defenseless, and she dragged both arms up to hide her face in shame—but
"Aww, now now. Nothing to be embarrassed about. All you have to do is enjoy it."
"Ah... aahh... my lady...♥"
Under Cheon Hwa-yeon's guidance, she was back in position in no time.
Shlick—squelch—♡
"Nngh... oohhk...♥"
With nothing more than a gentle roll of the hips, Seo A-ra's face went slack in a way it never had before—utterly foolish. It was the uniquely vulgar expression of a female who had gone completely loose, surrendering her body to the one on top of her.
Cheon Hwa-yeon saw that the moment was ripe. She worked her hips in a slow, dense rhythm and spoke.
"Miss Seo A-ra. Shall we make you feel a little better?"
"A little... moree♥...?"
Cheon Hwa-yeon whispered it in a low, insinuating voice. Seo A-ra's pale brow furrowed as if in refusal; Cheon Hwa-yeon smoothed it with her thumb, then traced down a smooth cheek to caress the underside of her jaw.
"Just once. Think of it as letting yourself be fooled."
"Nngh...♥"
Seo A-ra pressed her lips tight, still trying to show she didn't want it—but when Cheon Hwa-yeon rolled her hips a little wider, she tipped her chin up and folded at once.
"J-just... once... that's iiiit...♥"
"Lovely. Then let's be more honest with each other now♡"
The moment consent dropped, Cheon Hwa-yeon braced a hand on the bed and began to move her hips in a heavy, unhurried rhythm, without the slightest delay.
Squelch—schlick—♥
"Kk—nngh...♥!"
Seo A-ra's chin jerked up, and her juices sprayed in every direction.
"Does it feel good?"
"Y-yess... it... feels good...♥"
"And thanks to whom does it feel so good?"
"M-my lady... thanks to you, my ladyyy...♥"
Cheon Hwa-yeon drove her hips harder. Pleasure was being pumped into her in that comfortable position, and Seo A-ra couldn't last. She reported it exactly as she'd been told.
"I-I'm going to... cum... I can't... anymorre...♥"
"Fufu...♡ Then this is the last question."
"Nngh... h-hurry... I can't... hold ooon...♥"
At Seo A-ra's desperate plea, Cheon Hwa-yeon asked,
"Now, Miss Seo A-ra. Before you are a Warrior of Light, what are you?"
"A... concubine....♥ Your... concubine...♥"
"Say my name, please."
THUD—♡!
"Nnnnngh...♥! C-Cheon Hwa-yeon's... beloved concubine...♥!"
"Then whose pussy is this?"
"Th-that tooo... it's Cheon Hwa-yeon's...♥"
"Mm-hmm. Good."
Cheon Hwa-yeon seized both of Seo A-ra's breasts in a rough grip and slammed her hips as if to shatter the womb beneath her.
"Now then, last of all. This thing I'm pounding—what is it?"
"M-my womb...♥ it's my woommb...♥"
"Mm-hmm. Then this womb our Miss Seo A-ra has so carefully treasured—whose is it now?"
"Th-thaaat...♥"
Seo A-ra swallowed. She spilled a heated breath and swallowed again.
I shouldn't say this. The thought had only just crossed her mind when—
"Oh, come on! Say it already."
SCHLIIICK♡—!!
"Nnghoooohk...♥"
Cheon Hwa-yeon yanked on her breasts and drove her hips up even harder. Pleasure was wrung out of the womb taking those blows from her glans like water from a rag. Seo A-ra couldn't hold. She tipped her chin to the ceiling and declared it.
"You're offering it to me, then?"
"Y-ye...sss...♥ I'll offer—I'll offer it to youuu...♥"
"Oh my, how delightful. Then I'll give you a reward. Cum as much as you like♡"
"Ah... aahh...♥ aaaaaahh...♥!"
A thin, slender tentacle latched onto the clit of a dazed Seo A-ra and yanked it as if hanging her by the neck. In that instant there was nothing left to hold back. She came on the spot, tasting the greatest pleasure she had felt all day.
"Nngh... nnghaaa...♥"
Spurt—spurt—spuuurt—♡
"......?! Nngh... nngha... h-ho, hottt...♥"
An unbelievable heat bloomed from the thick, viscous semen climbing into her womb. It started in her belly, raced through her whole body, and in no time had occupied her down to the limbs and the crown of her head. Seo A-ra felt herself grow so hot she thought her heart might burst.
"Ah... aahh...♥"
A sense of exaltation and satisfaction she had never felt in her life seeped into every last cell. Drool spilled from her slack mouth, and she fainted clean away.
"Hah. It's been engraved nicely."
Smiling down at her, Cheon Hwa-yeon drew her cock out and rose.
"Ah... nngha...♥"
Even that alone was enough to make Seo A-ra cum once more. And as if it had sensed its master's climax—

—the tattoo on her lower belly flared with an ominous pink light and forcibly opened Seo A-ra's status window.
"Mm. I can see it now♡"
Worse, the window had not appeared in front of Seo A-ra. It had opened in front of Cheon Hwa-yeon. It was as if ownership had been reversed—and that was, in fact, exactly the case.
"I have no intention of being found out just yet, so let's hide this for now."
Cheon Hwa-yeon tapped a word at the top of Seo A-ra's status window. The word blinked a few times, then gradually faded.
"I'll look forward to our next meeting. My dear concubine."
With that, as if to mock her, Cheon Hwa-yeon moved the status window in front of Seo A-ra's closed eyes.
"Ah, I almost forgot."
"Nngh...♥"
She gave Seo A-ra's clit a light flick, fluttered her folding fan, and drew the blanket up over that pale pink tattoo.
"Farewell, then."
"Kk—ahh...♥"
On her way out, Cheon Hwa-yeon gave Seo A-ra's pussy a few light pats with her palm. At that touch, Seo A-ra lewdly spread her legs wide, and a clear stream trickled from her urethra, soiling the bed.
"Oh dear, oh dear."
She stroked the hair of a Seo A-ra who was completely unconscious, panting in short, ragged breaths—and walked out of the room.
While Seo A-ra and Cheon Hwa-yeon were locked in that dark room, far from the city center, on a hard, deserted rocky outcrop in the outskirts—
"Feels like the match is settled, doesn't it?"
"Hah... hah..."
The voices of two women, one triumphant and one despairing, rang out across the stone.
"Urgh... nngh..."
Baek Hwa-rin murmured blankly, replaying a battle she couldn't comprehend.
"Why..."
"You don't know why you lost, do you?"
At the question from her opponent, who had drawn up close, Baek Hwa-rin barely managed to lift her head.

Her expression had gone slack and vacant, as if she'd endured not a battle but a relentless sexual torture, her shoulders twitching as though she might climax at any moment. Drool and tears ran freely down her face, and still Baek Hwa-rin was barely holding on, unable to accept a reality that made no sense.
"Frustrating, isn't it. You thought you'd blocked it, but it went right through. You thought you'd been cut, but it felt good. Ups-a-daisy."
"Nngh...!"
The Varg executive kicked Baek Hwa-rin's twitching shoulder and laid her out on the ground. Then she planted a foot on those taut abs and spoke.

"Nngh... aahh..."
"No need to think too hard about it. Simply put, I cut through the concept itself."
"Wh...at...?"
"Come on. I told you not to think too hard. Just go to sleep."
Without another word, the executive swung her scythe in a wide arc and cut through Baek Hwa-rin's neck.
"Nngh... aaaahn...♥ kyaaaaaahn...♥"
"Oh-ho. Those moans are a far cry from Her Majesty's, aren't they? You sound like a whore who's been ridden ragged."
The executive smiled down at Baek Hwa-rin, who clutched at her throat, screaming and convulsing in pleasure.
"Ahh... I finally have one of my own. A pet...♥"
That sadistic smile was the last thing Baek Hwa-rin remembered as she closed her eyes and went limp against the cold stone floor.
