19(2). Payback in Full
The nape of Sirin's neck dangled in the air, caught in Seolrin's grip, and bit by bit the force in that hand began to grow.
Seolrin's other hand was already buried to the root inside Sirin's pussy with two fingers, and with those hypersensitive nerves lit up all at once, Sirin's eyes flew wide open and her body began to shiver uncontrollably.
The smug face that always toyed with other people's heads and strutted around with all the leisure in the world was gone without a trace. In its place, cheeks flushed a deep, ripened red and eyes glassy with bewilderment were staring up at Seolrin.
"Aah, senpai… w-wait, wait a second!"
"What's the matter? This is what you wanted, isn't it?"
The corner of Seolrin's mouth curled into a smile.
When she gave her fingers a slight twist inside, Sirin's narrow, scorching passage clung to them slickly and squeezed down hard around every knuckle. The privilege of young flesh.
With that thick, dragging sensation of inner flesh being pulled along, pink nectar came trickling down over her wrist.
As explained before, when Sirin had fashioned her humanoid form, she had used Seolrin's body as the blueprint.
At first it had been a casual mindset — I'll just make myself a pretty woman's body — but the longer she spent at Seolrin's side, the more she had copied, little by little. She'd replicated every fine detail with painstaking care, and in doing so she had duplicated even Seolrin's trademark sensitivity, that weakness to pleasure, exactly as it was.
Truly a case of being caught in her own trap.
Seolrin hurled Sirin's floating body roughly down onto the sofa.
The restraint on Jeongsujeongdo had been lifted — the power and physique of Seolrin's true nature as a mutant were returning to her, and this superhuman strength was proof of it.
With a heavy thud, Sirin went tumbling across the soft cushions and hastily clamped her thighs together to hide her pussy.
But thanks to the black cube spinning ceaselessly overhead, her thighs, bound fast by something invisible, were forced into a wide M-shape, splayed open on either side and locked in place.
"Wh-why…."
"Curious?"
"We're inside the Facility — why, why can you use your powers?! That's cheating!"
"The Facility Director made an adjustment, remember? If you cross the line too far, I pop out. Simple rule, right?"
"If you mess with the Director's brain again…!"
"And what good would poking at that thing — no, that monster's brain do me? Unless my true self shows up in person, there's no winning hand there."
Seolrin stalked slowly toward Sirin and slid one knee up onto the sofa.
Between the undone buttons of her shirt, Sirin's pale, porcelain-white chest rose and fell in ragged gasps — up, down, up, down.
Her whole chest was stained crimson, and her nipples, that ambiguous shade between soft pink and pure white, stood stiff and erect, trembling pitifully at the touch of the cold air.
Seolrin gripped Sirin's chin with one hand to pin her gaze in place, then pushed the other hand into her mouth.
She forced her fingers past Sirin's lips, stroked her tongue until drool spilled out, then used that saliva as lubricant and smeared it across her chest. And then, she seized the dampened breast in one firm squeeze.
"Nngh…!"
It filled her palm to overflowing — yet sat slightly smaller than Seolrin's own chest.
Savoring the feel of that soft flesh compressing under her hand, Seolrin caught the nipple between her fingers and pinched it, pulling it long and taut.
Finger play.
To Sirin, whose every movement was sealed away, it registered as a staggering surge of pleasure.
With a soft pop from her spine, her back arched deep into a C-shape and a thin scream burst out of her.
"Hah, nngh… senpai, s-se-senpai, your fingers, please…!"
"Trying to break in someone else when you can't even control your own body. How arrogant."
"My fing— my fingers…"
"Hm? You want more inside you?"
Squelch.
With an obscene, wet sound, Seolrin slowly withdrew the fingers wedged in Sirin's soaked crotch — only to pretend she was letting go entirely, then drive them right back in, thrusting deep into the innermost spot.
Her fingertips found the soft ridge that bulged noticeably against the front wall inside, and when Seolrin crooked her fingers and raked at it relentlessly, the way one does alone when touching herself, the star patterns in Sirin's eyes contracted wildly, shrinking to pinpoints.
"Aahang…! No, not there, not there, ah, aaang…!"
"What do you mean, no? You're loving this."
Twisting her wrist, Seolrin deliberately cranked those squelching sounds up louder, and Sirin's arousal burst out like a fountain, drenching Seolrin's hand and the sofa through.
Drool overflowed from between Sirin's lips and slid down her chin, and the small flesh-tendrils poking out from her ears were quivering nonstop.
"Aha… so you were stowing your tentacles in your head, huh?"
And with that, Seolrin pressed her lips to the nape of Sirin's neck.
Nip.
She bit lightly at the skin, then licked a broad stripe over the spot with her tongue, savoring the sweet taste of sweat laced with fruit.
Her lips traced down along the collarbone, then slid along the curve of the swell of the opposite breast, plump and heavy.
Smooch… shluuurp.
If what she'd done earlier counted as fondling, what Seolrin was doing now was closer to a baby's greedy hunger for milk.
She rolled the stiffened peak and nipple mercilessly with the tip of her tongue, teased them with her teeth, then sucked hard enough to hollow out her cheeks.
"Haah… aah, senpai, stop, I'll die! I'm really… I'm really going to die…!"
"Die of what? With abilities like yours, even your true self has to be immortal. Tear apart or break however you like — I'll put you back together."
To answer Sirin's talk of dying, Seolrin paused her suckling for a moment.
A bonus: when she pulled her lips away, a long strand of saliva stretched out between them like melted mozzarella.
Now hunting for her next target, Seolrin ducked her head down between Sirin's splayed legs.
The area around Sirin's pussy was drenched through with clear fluid, spitting up nectar with every breath — spurting, spurting — like a man's climax.
The smooth, pink, fully bloomed entrance quivered and gaped like a pleading little mouth, begging for more of Seolrin's fingers.
Seolrin stepped down off the sofa and dropped Sirin's legs lightly over her shoulders.
"You had some fun licking me earlier, didn't you?"
"…?!"
"So I'll return the favor. That's only fair, right?"
Bowing her head, Seolrin buried her face between the glistening petals of Sirin's flower.
Slurp.
"AAAAGH…!"
With her senses wound up past their limit, Sirin's moans had transformed from lewd into something strange — bestial, like a scream being torn in half.
Seolrin pointed her tongue and flicked it rapidly against the taut, fever-hot little bud, then sealed her lips around it and swallowed it whole, sucking.
Squelch, shlk, slurp, chuup.
Flesh met flesh in a thick, wet collision.
Seolrin gripped Sirin's hips with both hands and yanked them hard against her face.
Her fingers dug into the flesh of that rear, leaving round impressions, and Seolrin's nose and chin grew soaked with the nectar Sirin kept spilling.
"Se-se-senpai… why is your tongue so lo—! Ah, nn, nnaah, aaaang…!"
Sirin bucked her hips, trying desperately to escape, but with her legs caught over Seolrin's shoulders and her rear locked in that grip, she couldn't budge an inch.
Not that the black cube would have simply stood by and watched, even if she could have.
Seolrin forced her tongue into the narrow crevice and scraped at the walls, scraped, kept on scraping, ravaging her fiercely.
Fluids sweetened with that honeyed scent poured into Seolrin's mouth; she swallowed them down with a gulp and drove her tongue in even deeper.
Part of Sirin's true essence took the form of tentacles, capable of absorbing and storing other anomalies and objects to spew out later.
The pink liquid now gushing out — that strange, brain-numbing taste — was the same compound as the pink fluid spewed by the tentacle that had once escaped from Research Team 2.
But before a Seolrin with her power unbound, the pink liquid was nothing more than a thick, sugary drink.
Haaah, tsk, squelch.
"I'm cumming, I'm cumming…! Senpai, my brain, my braaain…! Ah, aaang…!"
Sirin went rigid.
Like a statue.
Her fingers and toes twitched, and her stomach heaved and convulsed violently — so hard, in fact, that her sides visibly caved inward.
With her flanks sucked in like that, only her belly bulged out at the center — and needless to say, what bulged there was Sirin's womb, the one properly functioning organ she had left.
Fsssh!
At last she hit her limit — a massive torrent erupted from deep within her, drenching Seolrin's entire face and her shirt.
Perhaps from the shock of her climax, Sirin stared up at the ceiling, her jaw chattering. The odd little moans — ah, aaah — were a bonus.
Tok.
The black cube stopped rotating, and Sirin slumped down, limp as a broken doll.
Seolrin rose from her seat and stretched.
"…Hoooh."
Her cheeks, chin, and lips were all slicked glistening with pink fluid; Seolrin wiped it off indifferently with a fallen shirtsleeve, then looked down at Sirin, who lay convulsing and gasping like a frog in place.
In this tedious existence of hers, this was the only amusement there was.
'Good thing it happens to be my taste, then.'
Click.
The black cube rotated once more.
About time, wasn't it?
Seolrin moved behind the sofa — and her retreating figure savored the afterglow as she went.
Seolrin's true self gave Sirin's disheveled blonde hair a languid, lazy-eyed stroke.
"Cross the line again, and next time I punch straight through that womb of yours…?"
With those words, the light drained from Seolrin's eyes, and the black cube slipped itself neatly back into her pants pocket.
***
She opens her eyes.
"…Ugh."
Her head felt heavy and stiff, as if someone had set a boulder on top of it. Her mouth tasted foul, and every joint in her body ached as if it had been knocked out of alignment.
"Agh… my back… am I getting old?"
Groaning, she pushed herself upright on the sofa.
She distinctly remembered being dressed neatly, yet now her clothes hung somehow loose and askew, and the inside of her pants was uncomfortably, disgustingly sticky.
She slipped her hand down into her pants and brushed the sensitive area — and her fingers came away with something like a crust of dried, hardened nectar clinging to them.
"First thing in the morning, seriously…"
Tsk.
Clicking her tongue, she used two fingers to wipe away the moisture matted between her legs and scrubbed them roughly against a tissue.
A faint scent of fruit and sweat kept reaching her nose, churning her stomach. She felt like she might throw up.
Below the sofa, there came a rustling sound.
She looked down and saw Sirin lying face-down on the floor, staring blankly into empty air.
Her shirt had had its buttons torn clean off, and her short skirt was rolled up past her hips — an absolute wreck. The star patterns in her blue eyes had completely lost focus and drifted loose, and dried drool had hardened white at the corners of her mouth. Whoever had dressed her had done a truly sloppy job of it. Right?
"…You. What is all this?"
"Se-Senpai…"
"What happened to you? And why are your clothes torn up, on top of it?"
Lee Sirin's face twisted with fear.
An expression Seolrin had never seen before.
"I-I'm fine."
"Are you hurt anywhere?"
"N-nothing, I'm, I'm perfectly fine…"
"Fine, my ass — your legs are shot, you can't even stand. Go wash up, now. The Director's going to chew me out over this."
Throb.
Her head ached. A migraine, maybe?
