Abandoned Mine
"Ohhhhoh!!"
Damp sky-blue hair, hanging all the way down to her waist, whipped wildly about with each violent shake of her head.
A soft, pliant tongue pushed in from behind her hips, doggedly zeroing in on the puckered ring of her asshole—an entrance that had never once taken anything inside it.
"Naaaah! That's, that's not a place you put things iiin—hiii!"
Sucking, licking. Lips pressed flush against the entrance, kissing it deep, pulling outward on those wrinkled folds until they loosened—
Then the tip of the tongue sharpened to a point and pressed, slow and insistent, into that tiny opening.
The soft, young asshole squeezed down in a desperate bid to seal itself shut—but the entrance, drenched and sodden with warm saliva, plundered beyond bearing, finally slackened and fell.
"Eeeeeeek!"
Her slender waist shuddering, her bound body sprang up into the air like a drawn bow.
Thick drops of tears spilled from brimming blue eyes and rolled, one after another, down her cheeks.
But.
Her body was honest—honest in the exact opposite direction of her shame.
Twitch. Twitch.
Her quivering hidden flesh parted slightly, entirely without her consent, pitiably baring its flushed pink interior.
From within that entrance, opening and closing without managing to do either,
translucent love-juice beaded up, and then, unable to hold itself back any longer, trickled down the soft inner skin of her thighs.
Nox's fingers slid slickly into that dampening crevice.
With his fingertips, he stroked slowly up along the soft, soaked flesh within, as if raking it down.
"Hiiiiiiiik!!"
At that pressure pressing deep against the inner walls of her pussy, electricity shot up her spine and a climax burst through her.
Mio stayed in position, hips thrust fully back, her slender thighs wrapped in white knee-socks trembling uncontrollably as her knees buckled and gave.
"Not yet. It's not time for you to collapse."
His dark-red tentacles snapped around her small, crumbling body and hoisted it back up into the air.
As though catching a marionette whose strings had snapped.
And even in that moment, Nox licked up and swallowed every last drop of the sweet nectar overflowing from her parted slit.
Each time that slick, scalding liquid slid down his throat, he could feel the energy of erosion trickling back into his parched, withered core.
"Hikiiii.. you're.. you're licking me up againnnnnn!"
The sensation of his tongue joining his fingers inside her pussy wrung her whole body into a twist, spilling an even sharper cry from her lips.
But then his finger, replenished with energy and full of vigor once more, pressed steadily against her utterly slackened asshole.
Shloooooop.
Even after all that loosening, it still gripped his finger with a springy, elastic hold, squeezing tight around him.
"Don't put your finger in theeeere!"
"I don't want that! I don't.. so please..."
Fierce refusal. She clenched her asshole for dear life and screamed.
But it lasted only a moment.
The instant Nox's tongue-tip stroked up along the red flesh below once more—
"Nghaaaang!"
Mio gasped out a sweet cry, and in that instant her slackened asshole relaxed open, swallowing his finger in.
Then that finger began to move, slowly tracing a circle deep inside her.
He had sucked and licked her until she was melted to mush out front—
yet the muscle within still held rigid and stubborn, refusing this unfamiliar intrusion.
The unyielding tightness of a virgin ass, never once having taken anything in.
"Hh, hh... no... that's, that's not a place that..."
Even as she whimpered in a voice melted beyond recognition—
the entrance, slicked smooth with warm saliva, could not push back the finger pushing its way in.
No—it did more than fail to push it out.
Shloop—
Along that oil-slick surface, an entire finger slipped helplessly inside.
"Hiiiiiit?!"
Her body stiffened in resistance while her entrance surrendered all on its own—and at that contradiction, Mio's small body flung itself upward, bow-taut, clinging to the tentacles.
Her slender waist trembled violently.
Her sock-wrapped toes scraped hopelessly at empty air.
"It, it went in... in the back... it went in my baaack...!"
The tail end of that molten, crushed voice cracked apart into a scream.
The finger circled, slowly, deep inside her.
Against the still-clenching muscle within, it used its slick saliva as lubricant, rubbing and pressing, peeling that resistance away one layer at a time.
A circle, and then another.
"Nghaang... hhah, hiit... it's strange, it's strange... if you do that, if you...!"
The rigidly braced muscle lost its strength little by little, little by little, under that relentless friction.
And at the same time—
Nox's tongue never stopped stroking up over the pitiably quivering red flesh below, rekindling the embers of pleasure that had been guttering out.
Lick—
"Hiiit!! Ah, both... front and back... hiii...!"
Simultaneously ravished from both her pussy and her—no, her ass—her blue eyes had already lost all focus, swimming dizzily between the two-pronged assault.
Each time the hot tongue stroked her front, her hips bucked upward.
And in time with that jolt, the muscle inside her clenched tight around the finger buried in the back, entirely of its own accord.
Clench, then release.
With every clench, a scream of a cry tore from Mio's lips.
With every release, a melting moan spilled out.
"Nghnn... hiit... haaang... no... not there... not that place..."
Even as she said it was impossible—
her exhausted body drank in that two-pronged stimulation to the fullest, trembling in small, ceaseless shivers.
Something hot came crawling up her again from the tips of her toes.
Up the length of her slender thighs.
Past the narrow dip of her waist.
And deep within her belly, something swelled precariously upward.
"Hiik, hit... it's, it's coming again... this time, both at the same tiiime...!"
Her breathing turned ragged.
The strange fullness in her asshole—while at once, deep inside her pussy, his tongue lapped up her love-juice in great gulps, catching her clitoris in passing as its mouth closed over her again and again.
The finger circled round and round at the entrance of her ass, mingling with that bizarre sensation of needing to expel something—a dual feeling she had never once felt in her life—and that sensation tangled with pleasure and crashed over her.

And then—
The pleasure welling up from front and back at once pierced straight through her emptied skull and turned it blinding white.
"Nghaaaaang!! I'm, I'm coming agaaain!!"
Spurt!
Her small body, already wrung dry who knows how many times, still arched upward in another great, bowing curve.
Between her splayed legs, pale love-juice burst free and scattered into the air.
Spurrrt!!
In the throes of her climax, her asshole clamped down around his finger again and again, and with every clench the flesh in front convulsed in tandem, as if seized by spasms.
"Hii... iit... haaang!!"
Spurt...! Spurt!
Her hips jerked up violently, then went limp and slack.
Her small, sock-wrapped toes splayed apart one by one, curling as if grasping at empty air.
Her delicate body shivered in fine ripples, unable to pull free of the lingering aftershocks of her peak.
"Haa... haa... heh... the back... at the same time... heeeh..."
Between her utterly ruined young lips, drool trailed down in a thin thread, wetting her chin.
As her small body began to crumble, the black tentacles snapped around her and hoisted her back up into the air.
As though catching a marionette whose strings had snapped.
And even in that moment, Nox licked up and swallowed every last drop of the sweet nectar overflowing from her parted slit.
Each time that slick, scalding liquid slid down his throat, he could feel the energy of erosion refilling his parched core once more.
And then, in that moment—as she lay swaying in the afterglow of her orgasm—
something strange began to seep out from the fingertip buried deep inside her asshole.
That hard, short sensation slowly melted soft and began reshaping itself into something new.
"Inside... hit!..."
Drenched in orgasm, half-conscious, Mio belatedly voiced her unease.
"W-wait, something inside my butt—"
"Shh. Still, I'd say we can move on to the main stage now."
That softened thing soon stretched out long, burrowing deeper and deeper inside her.
It was no longer a finger.
"Hiiik?! What's coming n—hiiit!!!... something, something got bigger inside me...!"
A tentacle. A strand of tentacle, born from the tip of Nox's finger, was swelling inside her ass.
That slender thread drank in her body heat and filled her inner depths with its alien presence.
And that tentacle never once held a single, constant shape.
It thickened.
Thinned.
Bristled with knotted ridges, then smoothed back to sleekness.
"Ngha?! Wh-what... it keeps, it keeps changing shape... and now it's crawling up again—hiit!!!"
That unpredictable, irregular movement—coupled with the terror of something climbing the wrong way up her excretory passage—made her waist curl in on herself as she shuddered in fear.
And then—
The tip of the tentacle changed direction.
Not burrowing deeper.
Pressing, with deliberate weight, against the deep, thin wall of flesh that faced her womb—then slowly beginning to withdraw.
"Uh... uhh? W-wait... this, this feeling...!"
The tentacle, kept at a moderate thickness with a smooth surface, dragged across the wrinkled folds as it was drawn out.
The finger pulled free from the entrance of her ass—
"No... no, don't come out!! It's wrong!!"
"Something's, something's happening, please stooop...!"
The sensation of expulsion.
Nothing like the sexual kind—an overt, mortifying pressure bore down on her entire lower belly.
Mio clenched her asshole with everything she had.
I must not let it out.
Here, of all places, with that man watching.
That—she could absolutely never, ever let him see that.
Hold it, I have to hold it...!
But the tentacle pushing outward against her inner walls—as if sneering at that pitiful resistance—
turned around. The tentacle that had been slowly withdrawing pushed back inside.
"Hit!! This time it's.. it, it went back in!! Wait, why is it going back in, hiiit!!!!"
And then—
Beyond a single thin layer of flesh, in that place she had been so desperately ashamed of only moments ago—
the wall of her womb, the wall her Barrier had defended so stubbornly—
the tentacle caressed it from behind, from the side of her ass, sliding around as if taking a shortcut.
Separated from the back of her womb by nothing more than the thin wall of her anal passage—indirect womb massage, performed in full.
"Hiit!! KYAAAAAAAAAAANG!!!"
Mio's hips bucked and wrenched upward one more time, hard.
