Tentacles (2)
The heavy mass that slammed into her cervix drove straight through her entire lower body.
Suspended in midair, Yuna's body arched taut as a drawn bowstring.
Her pelvic bones felt ready to shatter wholesale; the crushing pressure twisting both hip joints toward dislocation surged up her spine.
A single rough, merciless thrust.
The enormous pillar that forced its way through her narrow entrance savagely crushed the delicate folds of her vaginal walls, piercing in one brutal stroke all the way to the farthest edge of her most intimate sanctuary.

"Ugh…! A-Aaaah!!"
Red capillaries burst like spiderwebs across her eyes, rolled pure white. From her throat, bent back toward the ceiling, animal death-screams tore free without pause. Her vocal cords shredded; the taste of blood flooded her mouth as the desperate shrieks slammed against the tile walls and echoed back.
She could not breathe.
The diaphragm beneath her ribs convulsed madly, starving for oxygen. Yet her nervous system, completely paralyzed by the extreme pain, had forgotten even the most basic act of forcing air into her lungs; her body simply spasmed and trembled in empty air.
The sensation of that massive flesh wall filling her birth canal to overflowing, swelling the mucosal lining until it felt ready to burst.
Each time the broken flashlight on the floor crackled and spat light, the shadow of her naked body hanging in the air—and of the enormous pillar spearing between her thighs—rippled darkly across the walls.
The searing agony of her delicate vaginal membranes tearing in dozens, hundreds of places shot straight into her brain. But the thrashing against that ripping pain lasted only a moment.
The burning gradually lessened. She felt the torn flesh being forced to knit itself shut. The dull, bone-crushing throb in her pelvis subsided.
Deepest inside, the movement of the massive primary tentacle that had been cruelly grinding against the mouth of her womb began to change.
The merciless, destructive pounding stopped dead.
A pulsing mass of flesh hung motionless in the air. Then that huge, grotesque thing began a slow, sticky motion.
The surface texture that had been scraping her tender inner walls like sandpaper shifted. Before she knew it, it had become something so soft, so wet, so slick with mucus that it made her skin crawl—clinging to her membranes.
This was no longer a thrust meant only for destruction or slaughter.
That soft change burrowing into her mucosa was preparation for breeding: the instinctive caress of a male about to mate.
The hot, throbbing lump of flesh began to crawl like a snake down her tight, clenching walls, carrying its pulse with it. It licked, rubbed, and seemed to suck at every last sensitive fold with greedy, obsessive thoroughness.
With its blunt, soft tip it gently stroked the tightly closed entrance to her womb, coaxing that red inner space to open of its own accord—a courtship.
Yellowish sticky mucus continuously oozed from the tentacle's surface. It became natural lubricant, seeping without a single gap into the torn, blood-flecked walls of her vagina.
Squelch. Squelch. Squish.
"Ugh—! Hhk—!"
The wet friction sounds tore through the silence of the sealed toilet stall. The thick, viscous noise of flesh perfectly pressed against flesh and grinding together drilled into her eardrums and toyed with her brain.
The reek of rusty blood, of sewers, and a sweet-and-rank animal fluid so sharp it stabbed the nostrils seized the narrow space.
Her arms and legs, bound as if crucified, had long since lost circulation; sensation itself was fading.
"Hhk, ughk—! Hhh…"
Her waist jerked upward on its own—not from overwhelming pain, but from the skin-crawling stimulation of that massage. Her body, stripped of reason, arched and released like a bow in time with the tentacle's rhythm. The wretched reflexes of thoroughly controlled, violated flesh twitched.
As the mating stimulation climbed her spinal nerves, the thread of her reason melted like candle wax into a dizzying haze. In direct opposition to a mind crushed by extreme shame and terror, the tentacle's sticky caresses forcibly wrung out a depraved spasm that trembled from deep inside her torso.
The womb seated at her very core shuddered, contracting and relaxing in time with the invader's movements. Her toes curled stiff; uncontrollable panting leaked between her lips. Blood had clotted and hardened around her tightly bound wrists, yet even that pain was swallowed by the tidal wave of pleasure boiling up from her lower body.
Other auxiliary tentacles began to rub stickily against the sensitive clitoris around her flushed vulva. Hundreds of tiny suckers licked her outer and inner labia at once, wringing out love juices by force. Clear fluid mixed with the yellow mucus and dripped down the insides of her thighs.
As if the preparatory caresses were complete, the primary tentacle buried inside her began to pulse violently. The thick ducts running through its massive shaft all swelled at once. A heavy vibration rose from the depths of a swamp, drawing up boiling-hot liquid.
Woooong.
A low-frequency rumble carried a massive, gulping wave along her vaginal walls and through her entire viscera. The vibration shook her pelvic bones, climbed her spine, and set the inside of her skull ringing.
Gulp, guuulp!
The explosive pulse peaked and surged.
Puuuk—!
The tip of the tentacle forced its way through the already stretched-to-the-limit slit of her cervix and flared wide open. From that hole, like a dam bursting, an enormous volume of semen erupted in a waterfall.
"Hiiik…! Khh, mmpf, aaaah…!"
In an instant a maddening heat filled every empty space inside her belly. This was no mammalian body temperature. It was the scorching sensation of molten lava poured deep into her organs.
White seed as viscous as thick flour paste compressed and packed her womb without a single gap. Heat that felt ready to scorch the inner walls white, and a heavy foreign weight pressing on her stomach, spread from her lower abdomen through her whole body.

Under the endless pressure of the semen her womb swelled as if it would burst. Hot liquid crushed her organs, compressed her bladder, and pushed up toward her solar plexus. Her eyes rolled back; only dry, hacking coughs spilled from her mouth.
But the greed showed no sign of ending there.
The first massive tentacle gulped out every last drop of hot semen, then scraped slowly back out of her narrow canal. The instant it withdrew, a second thick tentacle waiting in the air lunged into the vacant space with perfectly calculated timing.

"Uup! Hahk, uuuk!"
Slap! Thunk! Squish!
A violent changeover that allowed not even a single second to catch her breath. Driving ahead of it all the yellow mucus and leftover semen smeared around her entrance, the second tentacle crushed her walls even deeper and more mercilessly as it bored in.
Her birth canal, stretched beyond recovery and stripped of all elasticity, had completely lost the strength to close; it had become nothing more than a wretched meat cave that simply swallowed the beast's flesh whole.
Cough, cough, phwah!
The second tentacle likewise jammed its head against the cervix that tried to seal shut and immediately began spewing hot seed in a frenzy. The thick white fluid had no time even to trickle down the uterine walls. Driven by the endless pressure of new, hotter fluid, the semen was ruthlessly compressed into every last corner of her womb.
The rotation never stopped. The moment the second withdrew, a third tentacle came flying in without fail.
Squish! Splat! Phwah!
One pulled out and the next shoved in without a hair's breadth of gap, then poured hot seed into that same narrow space—an endless cycle. Endless piston thrusts. Mucosal walls stretched to tearing. And the ceaseless repetition of ejaculation.
The narrow bathroom reeked so thickly of rank, throat-choking sweet animal semen that it stole every last scrap of oxygen. Over the flickering flashlight on the floor, the sticky shadow of her body hanging in the air and being endlessly violated layered itself again and again.
The slender frame suspended in midair was jerked roughly back and forth without rest. Only the wet, explosive sounds of flesh violently colliding with flesh ricocheted off the tile walls and filled the room.
The total mass of liquid being madly injected had already far exceeded any biological womb's capacity. That physical limit-breaking made her once-flat lower abdomen begin to swell like a woman in the final month of pregnancy.
At first it was only a bulging lower belly; successive ejaculations from the tentacles pushed the enormous expansion up past her pelvis, around her navel, and finally just beneath her solar plexus. Blue and red veins stood out as if ready to burst across the thin belly skin stretched to balloon-like limits. Beneath that skin stretched so thin it looked ready to tear, the hot semen the monster had poured in was so full that its heavy sloshing waves were clearly visible to the naked eye.
The swollen womb mercilessly crushed her other organs upward and sideways. With her stomach and intestines flattened and her airway feeling sealed, even normal breathing became impossible. When she tried to inhale, her diaphragm had nowhere left to descend.
"Hhhk…! Khh, too much, it's coming in…! Aaaah, my belly, ugh, my belly's going to burst…!"
A hoarse voice. A metallic plea mixed with the sound of swallowing broken glass forced its way past her lips along with bloody foam. Her face—smeared with tears, snot, sticky saliva, and the red blood from biting her tongue—had taken on the form of a female whose reason had completely collapsed.
The predators did not stop.
They rubbed the uterine walls even more obsessively and stickily, raising the injection rate of semen another notch.
Gulp, phwaaah!
It was the sticky motion of creatures certain that this warm-mucosa female host would become a meat mother who would take their seed, gestate countless young, and expel them.
That certainty, however, soon smashed against an invisible barrier and shattered.
The boiling-hot semen that had packed her womb to bursting. The very instant those sticky fluids tried to cling to the delicate mucosa and implant—
Deepest inside her body, the shaman bloodline engraved at her foundation, the invisible barrier, reacted with ferocious force.
Paaaat—!
Invisible to the naked eye, yet on the spiritual plane a light so intense and sacred it would have seared the retinas white exploded outward, wrapping the entire inner wall of her womb. It was a sacred wave of rejection that allowed not even a hair's breadth of external contamination.
The overwhelming force of refusal the barrier radiated instantly converted into merciless physical repulsion. It ripped away, with a force that felt ready to flay skin, the beast's sticky seed that had been clinging to the uterine mucosa trying to mix genes.
Bubble-bubble.
With the sound of boiling foam, the enormous volume of semen filling her belly churned and began to reverse. Far from implantation, even the slightest absorption was thoroughly rejected by stubborn purification.
The vast mass of liquid trapped in the narrow space, with nowhere left to go, yielded to the force squeezing from every direction and began to pour madly toward the exit.
Slurrp. Squelch. Splat.
Through her vaginal entrance, stretched and tattered beyond closing, an enormous volume of semen reverse-flowed like a completely shattered dam and cascaded out in a waterfall. Between the red flesh walls that would not shut, opaque sticky white semen and yellowish mucus clumps gushed out like vomit.
Hot, sticky ropes of semen streamed down the bare inner flesh of her raised thighs. The fluids cut through the air and struck the tiles with endless splat, slap, and splash, building bottomless pools.
It was like endlessly pouring filth into a giant bottomless jar. No matter how much hot seed they poured in, not a single drop was allowed to soak into the mucosa; every last drop was driven straight back out. Under the sacred pressure of expulsion it was even whipped into white foam as it was ruthlessly vomited outward.
The physical force trying to ram seed in, and the repulsive force trying to drive contamination out. Those two enormous powers collided desperately with her narrow, fragile birth canal caught between them. The more the collision raged inside her belly, the more the torn mucosa trapped in the middle was scraped and abraded, raw flesh ripped away in agony.
As if startled by the stubborn refusal, the rough piston rhythm of the tentacles suddenly stuttered and stopped.
A brief silence. Only the wet plop of semen hitting the floor filled the space.
Then the direction of the mating was completely revised—from forcing by strength to a softer, coaxing motion.
"Hiiik?!"
One thick primary tentacle that had withdrawn and been pacing the air carefully slid back inside like a snake, against the waterfall of semen. This was no violent injection or blow meant to tear the walls. Its blunt, soft tip licked thoroughly between the hypersensitive folds of her inner walls, caressed them, sucked at them, producing an intensely intimate vibration.
Woooong—
A fine ultrasonic vibration stimulated the mucosal nerves directly. At the same time the other massive auxiliary tentacles wrapped around her lower body spread wide and covered her lower abdomen—swollen tight with semen—like a giant palm, gripping it.
Round and round. Sticky, heavy friction. They began to massage her bunched belly carefully, applying strong pressure from outside inward. An attempt to somehow induce implantation by kneading and compressing the womb from the outside, forcing the semen deeper in.
"Ah, ahhhk…! Aaaah, hahk, please…!"
The foreign sensation of something gently stirring and toying with her deepest insides. On top of that, the crushing pressure of hands kneading her organs through the thinned belly skin from outside. Caught in that pincer attack from within and without, her flesh broke past every limit it could endure and convulsed wretchedly like a trembling aspen. Between her blood-flecked lips only ragged panting and meaningless babble flowed without end.
Yet even under that tenacious, obsessive coaxing and pressure massage, the barrier coiled inside her body permitted not a single inch of concession or compromise. The semen injected into her belly still clumped and reverse-flowed fiercely, endlessly spitting thick clumps down between her thighs to the floor with wet plops and thuds.
Slap. Squelch. Splat.
The white-and-yellow pool on the floor had swollen high enough to cover an ankle and reeked.
No matter how gently they caressed her walls, how they soothed and stroked her womb from outside, how much more semen they poured in—the result of rejection never changed in the slightest. The atmosphere inside the narrow bathroom that had been crushing the oxygen began to seethe and transform rapidly.
The sticky, sweet, rank heat unique to mating evaporated cold in an instant. In its place a murderous intent that felt like a rope around the throat, and a dense hostility, slowly rose and seized the space.
Faced with an unyielding, stubborn refusal, the beasts' patience finally hit bottom.
Crackle. Crunch-crack.
The surface texture of the inserted tentacle that had been gently rubbing her uterine walls suddenly changed. As if burned, it began to radiate high heat; the slick flesh rapidly discolored. Black blood vessels writhed and rose beneath the skin, and in moments the entire tentacle flushed a seething lava-red, glowing blood-crimson.
