A Pleasuring Corruption

"Ku—hu, uu—nnaaa!"

Both hands restrained above her head, the female knight — Alfira — writhed her waist back and forth as though enduring something.

Her purple hair swayed in time with the movements of her waist, the whole motion looking like a lewd dance to entice a man. However, she wasn't looking straight ahead but rather at the ceiling and the surrounding rock walls.

She did her best not to look at what was happening right in front of her.

The white knight Fiana was a little ways away from her. Her arms were similarly bound overhead, but she appeared to be unconscious, not even twitching.

"There! Right there! Deep—deeper!"

"Nn, fuaah—my boobs, nothing's coming out…"

In front of the girl were two women — one with silvery hair, the other with blonde — being ravished by mucus monsters.

Frederica was screaming as a tentacle as large as a child's arm shoved itself into her with enough force to lift her heels from the ground.

Forget her hips — each time she was pressed into with enough vigor to penetrate her body, her breasts shook violently. It was a sight that would certainly drive any man wild with carnal lust just by being there, but as a woman who would soon be having the same thing done to her, Alfira couldn't bear to look.

Meanwhile, Satia didn't have a tentacle inserted into her. Instead, her lower body was being caressed by the Black Ooze's tentacle while her tiny chest was licked and massaged by the child slimes.

Beneath the translucent slimes, the nipples atop her modest breasts had grown considerably large. The imbalance gave off a rather obscene feeling.

Satia let out her voice while watching her own nipples being kneaded and pulled on through the slime.

Both women were being ravished while standing, the same as Alfira, but they were different from the knight. They stood of their own will, accepting it. With their stances widened to shoulder width so as to not fall, their sensitive bodies accepted even the slimes' slightest movements. And above all — they moaned in pleasure with their mouths wide open.

All of this added up to something Alfira simply couldn't understand.

"—Nn, huu…"

While being shown the two treated like that, Alfira's lower half was tormented by the slime still inside her urethra.

The slime's paralytic poison was still affecting Alfira, but its effects had weakened considerably.

She felt some strength returning to her legs now, and she could even move them about freely since they weren't restrained.

However, the female knight — knowing full well that she should escape — simply kept biting her lips to hold back her voice while rubbing her thighs together, enduring this hellish shame.

People being raped by monsters was an extraordinarily abnormal spectacle.

Moreover, here were people who accepted the monsters' advances and immersed themselves in the pleasure.

Be it in ferocity or in tenderness, it was at a level no human male could ever achieve.

To a normal person like Alfira, far from understanding and embracing it, they would only feel disgust.

Unable to look straight on at the spectacle, the female knight averted her gaze, enduring it all while biting her lips.

"Fuaaah—"

It also looked like Alfira was suffering from the torment in her urethra. A stimulation utterly unobtainable through living an ordinary life assaulted the female knight.

If her hands were free, she might have covered her ears and curled up in a corner of the room to tremble. Humans being raped by monsters, accepting their advances, and even her own urethra being expanded — seeing this reality play out, it was obvious that she would want to hear nothing of it and push it all from her mind.

The sound of the two women's passionate cries pierced the female knight's ears, and the slime ceaselessly violating her urethra fed her a dull sensation.

Now drenched in her own love juices, her trousers felt gross against her skin. Her armor and sword had been taken from her when she was brought here, left back in the cave. She didn't know where they were now.

Insecure about being left in only her thick clothing, Alfira did her best to avoid looking at the lunacy in front of her while holding back her voice.

"Nnaah! A-aaah!! —Cu-cumming, cumming… d-deep inside, don't lick theeere!!"

Her beautiful blonde hair spread out, Frederica's bewitching body arched back for an instant. Then she spasmed strangely a few times, as though she'd broken.

Her breasts — so alluring they were attractive even to women — shook from her spasms. The next moment, they were constricted by tentacles as if being milked.

"Huaaaah!? O-ow—b-but I'm still…!"

Her still-convulsing body was prodded and pressed into to keep it rocking up and down. To match, the slime continued massaging her breasts while tugging on and kneading her nipples.

Her screams a testament to just how intense her climax had been, the beauty's expression reddened further from the pleasure, her tongue thrust out as she panted like a dog.

The thought flickered through Alfira's mind that the beauty had to be accepting the intense torment because she wouldn't be able to stand without the slime's restraints.

She wasn't permitted to collapse. This woman dripping with so much love juices and saliva couldn't possibly be the same person as before.

Alfira thought about how normal sex would finish once the man and woman climaxed once. She didn't have experience in the matter, but she did know that much.

She knew about the listlessness that followed a climax, the hesitancy to do it again. Even so, despite Frederica climaxing and saying as much, the Black Ooze showed no signs of stopping.

How long would it continue? At this rate, Frederica would die from cumming too much. Despite seeming to realize that, she looked as though she would accept whatever came.

"… …"

She had never even imagined something like this — being made to climax over and over again, being ravished regardless of her own will.

Her entire body licked by tentacles, the woman's most vital area pierced so forcefully it looked like she might break — a kind of sex where she was used like a doll.

This was something that didn't exist in Alfira's knowledge — an unknown kind of carnal union.

"—ah."

Realizing that she'd been captivated by Frederica's voice at some point, Alfira hurriedly averted her gaze.

She was embarrassed that she'd wound up so entranced by it.

(I have to get away somehow…)

"Nnaaah!?"

But at that moment, the slime in her urethra began to move back and forth. Her body had already grown heated from watching what was being done to Frederica and Satia, and now her whole body shook uncontrollably.

She didn't pee herself because her bladder had been emptied earlier, but she heard the squishing of other secretions overflowing from her vagina.

Her ears reddened at the lewd sounds coming from her own body, and she was seized by the urge to cover them, but the tentacle restraining her hands didn't loosen.

She wanted to escape from this hell as soon as possible.

This place frightened Alfira. Monsters were this world's enemies. Yet here were people who would accept those very monsters' ravishing.

Moreover, they were right in front of her. Women just like her were accepting these monsters' advances.

She was unbearably afraid.

Afraid that she herself might become like these women.

Even so, despite being made of mucus, the tentacles binding her wrists overhead were strong. Alfira's slender arms couldn't break free.

She only felt a disgusting sticky sensation each time she tried.

"A-ah—d-don't suck on my boooobs…"

The next thing to reach Alfira's ears was the opposite of Frederica's bestial panting — Satia's childish voice.

Caressed by the Black Ooze and various colored slimes, the girl didn't seem to feel any pain at all as her breasts were massaged. The only emotion in her voice was pleasure.

Perhaps because the overly gentle caress wasn't enough stimulation, her thin legs trembled slightly as she accepted the caresses to her chest.

Although her small breasts were being rubbed, their shape barely changed. She could see the girl's nipples through the mucus — they were being stretched out and pressed in so strongly they looked like they might break off.

Again, this was something rather obscene.

Her immature body smeared with mucus, she looked like she'd been tainted by the pleasure and fallen from virtue.

"Goshujin-sama… Satia, too… do it to Satia tooooo…"

She looked like she might collapse for an instant when her restraints were removed, but a tentacle kept her from falling by gently grabbing her. Rather than restraining her hands, it held her up by the waist.

Her now-free hands tried shooting towards her crotch, towards her most vital spot as a woman — unsatisfied by the light pleasure she'd received thus far.

The girl looked cute, like a doll, but after seeing her succumb to the pleasure and try to start comforting herself, Alfira gulped.

However, a tentacle captured her right hand, not allowing it to reach her vagina. Strands of her silvery hair, tied into a side tail, clung to her cheek, lending her doll-like expression an alluring quality.

"… Please, mercy…"

Spreading her legs — still being caressed by the black tentacles — she thrust out her waist and, with a far too wretched stance for a girl as beautiful as Satia… invited the tentacles in.

Even Alfira would have found such a pose embarrassing, but Satia showed no hesitation whatsoever. Yet the expression of the girl who'd struck this pose — one that would embarrass the female knight just by being seen — was dyed with an age-appropriate bashfulness. The gap between her body and her mind was plain to see, lending the mood an even more abnormally immoral air.

"—uaaah! Aaah, aaah!!"

An unfittingly large tentacle pushed its way into the flower that matched the size of Satia's body.

Secretions dribbled out of her, trailing down her thin legs and pooling on the ground.

Unable to endure its insertion, her small body shook and her knees gave out. Her vagina spread to the limit, and her face looked pained.

Yet although Satia still did her best to stay standing, it was clear she was at her limit.

The mucus tentacles wrapped around her seemed almost kind as they supported her.

"Goshujin-sama—th-there! All the way iiiin!!"

Satia had already reached her limit.

She still lacked sexual experience and the depth of her vagina wasn't great, so the tentacle reached her deepest point immediately.

When the entrance of her womb — what could be called a woman's greatest weak point — was pressed against, her small body went into incredible spasms as she climaxed.

And, just like with Frederica, the torment didn't end after she climaxed.

"Nnaa!? Huuu, haaah! Aaah!! Aan—aaaaah!!"

Rather than being pierced forcibly like Frederica was, Satia was slowly being injected into.

Alfira sensed that Satia's vital spot… her deepest point… was likely being relentlessly tormented.

The tentacle's movements were gentle, with little going in and out. Over and over, again and again — her sensitive places were prodded, licked, and rubbed.

She couldn't imagine what kind of torment that was, but from the state Satia was reduced to, the female knight's hips couldn't help but rock back and forth a little.

Even now, the sensation of a foreign object in her urethra still assaulted the knight.

Inevitably, she began to feel unsatisfied—

(I have to get away… before, before…)

"Haah, haah—nn, fuuu… ah…"

Still being forced to witness the two women's passion, Alfira panicked and attempted to remove the restraints on her arms.

The teeth she'd been using to bite her lips had parted at some point, her mouth letting out heated, shallow breaths. There was something sweet about her breathing.

Her white teeth caught the light, her small tongue just barely visible beyond them.

Blushing all the way to her ears, it was practically a miracle her eyes maintained any glimmer of clarity — her expression had already been warped by lust.

"Haah—stop, get oooout…"

The continuous, dull stimulation in her urethra was maddening. She wanted to try and run, but the resolve in her mind was being worn away little by little.

Her wrists' thrashing was slowly but surely lessening; conversely, her waist's spasming was growing faster.

The carnal desires bypassing the knight's will were swaying her body. Forced to urinate, her body now anticipated the pleasure soon to come.

"Damn, dammit—Haahn… no, no…!"

Alfira, struggling desperately to remove her restraints, started to repeat the same word over and over in delirium.

Even so, her movements were awfully dull compared to when she had first started. She couldn't even put any strength into her fingers anymore.

Yet still, the reason she didn't give up on her will to escape was that she feared she would die not as a knight, but as a woman.

Alfira didn't even want to imagine what it would be like to be raped like those two women.

For the female knight, who knew only about standard sexual intercourse even from the stories she'd heard, what was playing out before her eyes was—

Something entirely unknown to her.

She looked towards Fiana, who was still unconscious.

It was at that moment.

"Uuaaahn!?"

The slime inside her urethra began to thrust back and forth with unprecedented intensity.

Worked on by the slime, her urethra had grown large enough for a thin rod to fit inside.

With her crotch stimulated even through her clothes, she failed to resist and became fully aroused.

Unable to hold back her panting from the sudden stimulation, she looked up to the heavens, and the female knight's voluptuous body convulsed many times over.

Light flickered across her vision. Unable even to grasp the sensations of her own body, she stared blankly up at the heavens, surrendering to instinct as she kept on convulsing.

"Uu—ah…"

(N-no—no way… I-I… c-came…?)

Just how long had she convulsed for?

An instant? Several minutes?

The usual dull, painful sensation still stimulated her, so she kept going through intermittent, smaller spasms.

However, having grown somewhat used to that stimulation, she calmly considered her current state.

She'd cummed. Climaxed. Orgasmed.

Like the time she confronted the Black Ooze in the cave, she had been forced to feel it despite a state of extreme confusion.

Conscious that her urethra was being violated as she watched the two women having sex — she had climaxed as a woman.

Dumbfounded, she realized that — and tears spilled from her eyes.

"Haa—uahnn!? W-wait—I'm—!?"

The slime's piston-like movements accelerated once again. She could no longer even see the other women.

Her eyes shut tight as she bit down on her lip hard enough to draw pain. She did her best to bear the pleasure assaulting her body.

The slime responsible for that pleasure forcibly and violently pressed its way deeper inside her.

Already developed from its opening all the way to her bladder, even despite the sharp pain from its intensity, her urethra registered it as pleasure.

A licentious liquid made its way out of her yet-untouched vagina, wetting her underwear and trousers.

Her waist ignored her commands and went on convulsing.

Although Alfira started struggling with renewed vigor against the slime's sudden brutality, she couldn't remove the restraints on her wrists.

"Nna-aaah!? S-stop iiit!? Don't mooooove!!"

The fingers she'd been using to try to remove the restraints cramped as well. She couldn't put any strength into them.

On top of that, her body once again succumbed to the pleasure rushing into her through her urethra. Unable to defend against the surging tide, she fell back into a violent fit of convulsions.

"Ah—-!?"

Unable to withstand it, she reached her second climax.

A short cry escaping her mouth, her head fell back as her eyes rolled up beneath her still-closed eyelids.

She forced her eyes open. The walls around her were covered in slime mucus that caught the scant light. However, she paid none of it any mind.

Still dazed, all she could think about was the reality of climaxing one time after another.

"A-ah—n-no… st—p…"

Her voice did contain pleasure, certainly… but it also held a strong fear.

She was frightened.

Even Alfira had experienced masturbation many times over. However, she'd never climaxed back to back.

She had been able to satisfy herself by reaching it once and could cool down any sudden flashes of arousal through her work as a knight.

This, therefore, was the female knight's first consecutive climax… and it planted a seed of excitement and fear in her.

Alfira looked down in a panic. She was crying from the aftershocks of her climax and gulping back the saliva that had pooled in her mouth as she looked at the lower half of her body.

She couldn't stop her waist from spasming. She couldn't put any strength into her body now that it had just climaxed.

—And she couldn't withstand the pleasure.

Despite still being clothed, she felt even more embarrassed than if she were nude.

Desperately biting down on her lip, she tried tightening her urethra to stop the slime.

"Stop, stop stop stop stooooop!!!"

Still pleading frantically, she put everything she had into her lower body.

The more she tried to stop it, the stronger the strange feeling within her lower abdomen grew. The pleasure she derived from it grew stronger as well.

Even though she knew somewhere in her mind that this wouldn't stop what was about to happen, she couldn't stop trying. She poured every last drop of willpower and strength into the effort, so much so that her vagina and hips started to tremble strangely — yet even so, the outcome wouldn't change. It would only delay the inevitable by a mere few seconds.

The discomfort in her urethra grew as time passed. Together with a painful pressure in her bladder — the slime rushed into her bladder.

"—…"

She couldn't speak. No sound came out. She didn't know what had just happened. She could only sense a feeling of release in her abdomen as her body lost all strength. Even her expression grew slack to match her body. In a matter of seconds, she went from looking like an adult woman to wearing a shameful expression on her face.

Unable to see the way she looked in this place without mirrors, Alfira sighed out heated breaths from the extremely pleasant sensation coursing through her along with that release.

"Aah… aaah…"

The voice was muddled.

Whose voice was it?

She didn't know whose voice it was as she lay there with an unfocused gaze.

All she knew… was that she felt good.

It was too great a pleasure to be any ordinary climax. That climax invaded her mind like a deadly poison, blowing away even the disgust she felt.

Her waist's quivering didn't settle down for a while. Even those small movements reverberated in her bladder, sending more pleasure through her.

"Aaah…"

Various body fluids leaked from her, signaling that she'd reached complete ecstasy.

 

*

 

Brought to climax over and over again from an excretory organ she should never have felt pleasure from… Alfira, finally coming to her senses, was frightened.

(A-again!?)

As if it had been waiting for Alfira to return to consciousness, the slime inside her urethra resumed its activities.

The reason it felt even more oppressive than before was that it had absorbed the juice she'd been collecting within her bladder.

She couldn't exactly check its size, but the intense sensation of her urethra and bladder feeling like they might be dragged out together nearly blurred her vision.

Her tongue thrust out, her own voice joined the other two in the abandoned mine's darkness.

Her body's sensitivity had increased after climaxing, letting her feel the slime inside her urethra all the more.

She felt not just its violent back-and-forth motion, but even the ripples on the surface of its liquid body. She was getting close to climaxing yet again.

She knew this one would push her into a sense of hopelessness, but she was helpless to stop it.

She couldn't endure even when she tried. She couldn't escape even when she tried.

"No, no, nooooo!!"

Already convulsing for some time now, her lower body went into even more fervent convulsions.

A voice dyed in fear erupted from her throat.

"A-aaah!? Hii—s-sto… ooop!?"

The female knight was being tormented.

The convulsions assaulting her body grew ever more intense with no end in sight.

The same was true of her gasping. No longer holding back even slightly, she kept on crying out.

(No, no—stop, stop iiiiit!!!)

She thought that, but the only things to escape her mouth were meaningless gasps.

Looking at Frederica and Satia, the only thing Alfira felt was despair as she was brought to climax through her urethra.

(I-I'm not, I'm not like them—aaaaah!!)

Not like them. Alfira shouted in her mind over and over that she wasn't like those women who had accepted the monsters.

However, her body was accepting the slime's urethral torture. She no longer even felt pain from it.

Her head hung while her waist kept shaking from the crystal-clear pleasure.

"H-hah… Haah-haaaah—"

That dull, pleasant feeling stimulated her from the inside.

Her purple hair sticking to her cheek felt gross.

—Just then, the tentacle restraining her wrists let go. Alfira, unable to put any strength into her lower half after being brought to climax so many times, simply collapsed to the ground.

Her eyes closed in anticipation of the pain of her cheek hitting the slime-soaked ground, but what she felt was a soft cushion.

When she opened her eyes, she saw a bed of black mucus beneath her.

"Ah—"

Alfira sat with her legs folded to one side, the way a girl might.

Her shoulders moved up and down violently. Her eyes were wet and dull from the pleasure, the sharpness they'd once held now gone.

And more than anything — even without the paralytic poison, her lower body had gone numb from the excessive pleasure.

Her waist ignored what her mind told it to do and went on convulsing.

"A-ah…"

Suddenly, the monster — something she should have hated — shoved its tentacle right in front of her.

Brandishing it as though to show it off — it bared its majesty to Alfira.

(Something like that's—inside… them…)

Gulp.

Alfira swallowed her saliva.

Her womb throbbed faintly. Her quick, shallow gasps gradually intensified.

However, that was something Alfira herself hadn't noticed.

Even though her gaze was fixed unblinkingly on the tentacle, she did nothing — she just kept waiting for the tentacle to take the next step.

It had developed her urethra, and it had shown her the two lust-blinded women.

She had also been made to instinctively understand the concept of having sex with a monster.

That this body of hers was a woman's body that received pleasure, and that this monster was an existence that gave pleasure through sex impossible for humans.

What kind of thing was rape?

She'd been taught that as well.

That's why—

"S-stop…"

Her resistance was feeble, so much so that it surprised even her.

It wasn't the voice of a knight — but a woman. Alfira felt it.

She felt it.

It wasn't the voice of a knight that hunted monsters — it was the voice of a woman that was frightened of being raped. She didn't have any armor on. She didn't have a sword in her hand. Right then, she was a woman. Not a knight.

"Stop i—-nnn!?"

Her second attempt at resistance was cut short by the disgusting feeling of the tentacle entering her cleavage.

Making the best use of its characteristically slimy nature, it slid through the valley her clothes pressed tightly together.

Just like that, it ravished her breasts, coiling around the base of each one.

Alfira couldn't tell exactly what was happening since it was occurring beneath her clothes, but she could hear a slimy sound coming from her breasts.

"Kuh—g-gross…!"

That was a lie.

Even though they were being jostled about roughly, instead of pain, they conveyed only a dull sense of pleasure.

Because she didn't know what was happening, because it was happening under her clothes, because of the lewd sounds — she felt as though she were being treated like an object. The conviction that she could not resist was carved into her body.

She at least tried grabbing her own breasts with her now-free hands to hold them in place.

"Uu—nnn!"

However, she couldn't stop them, nor catch the tentacle from above her clothing.

Dexterously evading the hands trying to catch it, the tentacle went on ravishing Alfira's soft skin.

From a third person's point of view, her grabbing her own breasts made it look like she was masturbating.

And indeed, the stimulation from her own hands was something Alfira couldn't ignore.

While the mucus tentacle gently stimulated her skin, her own hands massaged her breasts intensely.

"Haah, haah!! C—c-cumming agaaaain!?"

"Huuu—ha, hah… m… mooore—"

Frederica's intense panting and Satia's sweet whispers tickled Alfira's ears.

And more than anything—

"Kuh—haah… Nn, nuu…"

She could clearly hear her own heated sighs as well.

The pleasure from her urethra's violation, the stimulation of her massaged chest, the panting reaching her ears — each and every one of those aroused the woman named Alfira.

The two hands she'd been using to try to catch the tentacle had, at some point, come to rest on her breasts. Her thighs rubbed against each other, unsatisfied.

Tears overflowed from her eyes as saliva spilled past her parted lips.

(Shit, shit—for me to… in a place like this…)

She cried out of regret, the tears running down her cheeks.

But her emotions were of no concern to the Black Ooze.

This slime was a monster, after all. It didn't care what humans felt. Its giving them pleasure — that was only to bring the mothers into peak condition.

"Kuh… stop it!"

The tentacle that had been violating her chest abruptly moved much more violently.

However, the female knight realized that this wasn't done to give her further pleasure.

She tried to thrash her upper body violently, but the movement was duller than she'd thought.

Fidgeting — no, moving in a way that would only tempt a man, she had no hope of escaping the tentacle's goal.

"Noooooo!?"

Her clothes were ripped open from the inside.

With her thick clothes and tight shirt that had been binding her breasts out of the way, the slime was laid bare to her eyes.

Not only did the tentacle become visible, but so did her sweat-steamed breasts — not just from the tentacle's mucus, but smelling of a woman in heat — quivering and showing off just how soft they were.

In terms of size, Frederica's might have been larger, but even without the support of underwear they didn't lose their shape — in both size and form, they were a man's ideal breasts.

However—

"Y-you! —I will definitely… kill you!!"

—Her nipples. What should have been on her breasts was nowhere to be seen.

She had bountiful breasts, with slightly large areolae — but no nipples, just a horizontal line on each breast.

(I was seen—by a monster—!)

Her cheeks flushed with a shame separate from pleasure, and the sharpness that had been fading returned to her eyes.

For Alfira, her chest was nothing but a complex — she had inverted nipples.

Even though it was a monster, she felt anger — and sadness — at someone else seeing them.

Although she'd been with several men, none of them had been alright with Alfira's breasts.

The female knight understood that her breasts were different from other women's. And that they weren't normal.

When men saw her chest, their lust would cool and they wouldn't go any further. That was because of how scarce sexual knowledge was in this world, but she couldn't even blame them for it.

Usually, when seeing something different, people grew wary.

But that was just something people cared about. As far as the Black Ooze was concerned, it was trivial.

Now that Alfira was only wearing trousers, it extended a tentacle towards her chest.

"Nn."

Changing from the manner it had been using thus far, it started massaging her chest gently, the way it had with Satia.

Her well-developed breasts changed shape as it played with them, producing no small amount of slimy noises.

Watching her breasts treated like toys, Alfira's hips began to move in small motions. She herself didn't even notice it.

And above all—

(My breasts. The tips, deep inside—)

Throbbing. They were throbbing. This was bad. The sensation that came next would ruin her.

That premonition, that conviction, filled Alfira's mind.

Although she tried to hold on to the tentacle with her hands, it was made of mucus and she couldn't restrain it. It just made another obscene, slimy sound.

The tentacle treated her breasts like toys even as she gripped it. Hidden within her breasts, her nipples throbbed ever more strongly.

"S-stop—"

She kept trying to catch the tentacle despite being unable to hold on to it, her breathing growing rougher.

Her body's sensitivity had increased after climaxing several times, and Alfira was now aroused to a level she'd never been before.

(Why, am I—-)

Being made to feel by a monster like this — it was a wretched feeling lower than a beast's, one that couldn't even be called taboo.

Monsters were the enemies of humanity. Humanity hunted monsters. That was the way of the world.

At the very least, every human other than the two devouring pleasure right before Alfira's eyes would answer the same way.

(I'm not—like… them—)

She had to be different.

Even if she was brought to climax by this monster, even if she felt pleasure, even if she was violated by it — she was different.

A haze filled her mind.

Her thoughts were clouded.

Ignoring her will, her body convulsed and the inside of her chest grew strained.

Alfira knew this feeling. It was the warning sign of climax — one that had been engraved into her body many times over the course of this single day.

(W-why—)

She clenched her teeth, shut her eyes… and tried to stop moaning.

Driven this far, enduring the climax was likely impossible. As someone with little experience — no, as someone with no experience whatsoever in being exposed to the pleasure a monster could bring, it was impossible for Alfira.

Even so, the reason she did her best to endure was that it came naturally to her, as someone who had devoted body and soul to living as a knight.

That pride, that dignity — those were what tried to support Alfira and keep her going.

But such a trivial thing was of no concern to the slimes.

As far as the slimes were concerned, whatever feelings or disgust the owner of the female body held towards them were inconsequential.

That's why no matter how long Alfira tried enduring, persevering, and denying it all, what the Black Ooze would do wouldn't change.

"Uuuuun—"

The tip of one of the tentacles massaging Alfira's breasts became thinner right before her eyes.

This too was something humans couldn't do.

As for what the string-like, thinned tentacle aimed at — its target was the peak of one of her well-developed breasts: her nipple, ever-so-hidden within her modest areola.

"Kuh, stop it!"

Restrained by the tentacles, her upper body shook violently as she tried to escape them. It was almost as though she'd just remembered she should.

However, the tentacles' grip was still strong. After climaxing over and over, her body couldn't muster even half its normal power, and she was unable to escape.

In the end, all she could do was shake her long purple hair and rich breasts. Strands of hair stuck to her sweat-damp cheek, and her expression was colored with despair at her inability to escape the restraints.

At the very least, her current attempts to escape — the swaying of her plentiful chest — could no longer be read as anything but a movement that beckoned her ravisher.

"… O-ow—"

It was only an advantage to the side doing the restraining.

When the tentacle constricting her breasts tightened further, she — having given up her struggles to that extent — looked pathetic.

The thinned tentacle hovered in front of the horizontal slit on her right breast — and aimed for the nipple hidden within.

"Nuuh…"

Unable to look away from it, she bit her lip.

Bracing herself to hold back her moans, she had no room to mind her expression. Her eyes were wide open, her mind fixated on the inverted nipples she had a complex about.

If she couldn't escape, she had no choice but to endure.

In her ears were the voices of the two others.

The knight order had set out to investigate this mine, so a search party would definitely be dispatched if they didn't return.

Until that time came, she just needed to endure.

As though she had forgotten her consecutive climaxes up to that point, her expression — while still showing some dread — held a strong will.

At that moment, as if waiting for Alfira to properly prepare herself, the thin tentacle slithered into the slit in her areola, tickling her inverted nipple.

"Nguuuh!?"

But just that was enough to jolt her body upward. Alfira couldn't even control her body's reaction to something as simple as that.

The stimulation was an utterly unknown shock to Alfira. With no friends who had inverted nipples themselves, she'd never been able to consult anyone about it, nor had she gone so far as to touch them herself.

When the viscous tentacle infiltrated her hole by exploiting its consistency, a sharp pain crashed into Alfira's mind.

She had been alive for twenty-seven years. In all that time, she had never once touched her nipples and had never felt this sort of stimulation.

Her nipple, sensitive enough to rival her clitoris, gave Alfira so much pleasure that it resembled pain.

"Stop, stop it! That's—"

Aware that her eyes had grown wet, she still tried to resist, her confidence not yet gone.

However, the lips she'd been biting to suppress her voice parted. Instead of a moan, what came out was a demanding voice for the sake of self-preservation.

She tried desperately to drive the tentacles out of her inverted nipple by moving her body, but the stimulation only intensified with each shake.

Even so, she couldn't stay quiet. The stimulation to her nipple was simply too strong. She had pleasured herself in the past through her vagina and clitoris, but never with her nipples.

The opposite might have been true had she been an ordinary woman. But because this was the first time Alfira's nipples had ever been stimulated, she couldn't come up with a way to endure it and simply kept shaking her body in a futile attempt to drive away the tentacles coiling around her breasts.

This created a rather vicious cycle. With every shake, a dull pleasure spread through her breasts, intensifying the stimulation to the nipple being licked and teased within.

"Hu, uuun. H-hah—sto-stop it, please…"

This time, a different tentacle took aim at her left breast — the opposite of the right one that had been pierced. This one too was thinner than a human's pinky.

Alfira knew what this meant.

(Cut it out! Stop—)

It wasn't the self-assured voice of a knight. It was that of a woman.

It slipped in.

At the same time, a noise came from inside her dampened pants.

"Hiii…"

The slime inside her urethra resumed its activities.

With her attention focused on her breasts, it was practically a surprise attack. Without time to even think, she clenched around the tentacle inside her urethra. As a result, she felt the tentacle moving inside her urethra all the more sharply.

It was as though the slime had known the moment Alfira's mind had let down its guard.

As if the caresses up to this point had been mere child's play, the tentacles wrapping her whole body came alive.

"Sto-p—it!"

Her urethra violated beneath her pants, the breasts of her naked upper body were tormented.

Her mind even stopped working properly for a moment.

Her mouth hung open as though she'd forgotten to close it. Drool dripped out and traced her lips. Her breasts were coated in mucus as the tentacles continued massaging them.

Her vision grew moist. Not even Alfira knew whether those were tears born of humiliation or joy, but her face was dyed with pleasure in every respect.

The once strong-willed eyes adorning her face now welled with tears that dripped from their corners. Saliva ran from her mouth and mucus from her nose. This was not the tentacles' mucus defiling her beautiful face — oh no, this was Alfira's own unsightly fluid.

If there were a mirror in front of her, just what would this female knight think of herself?

"Nng—uuuu…"

Its mucus glittering, a tentacle then hovered in front of her weakly parted mouth.

Moving slowly as if scooping up the drool dirtying her mouth, it defiled her glossy lips. Coating her entire lips in mucus as though applying makeup, it left a pungent, raw-meat odor deep in her nose.

Grimacing at the smell, she tried to turn her face away from the tentacle.

However, her face could only move sideways as far as her neck would allow — and even less, given she was restrained.

Enjoying Alfira's feeble resistance, the tentacle defiled not only her lips but also the nape of her neck, her ears, and her cheeks.

"Keh, sto—hyu!?"

As she tried to shout once more for the tentacles to stop, she let out a shrill voice from a sudden stimulation in her breasts.

When she looked down to see what had happened, her left nipple — had popped out.

Her eyes opened wide; she couldn't believe it.

It was something that had always been hiding within her areola, something that was supposed to remain inside her breast.

This was the first time she'd seen it, and she thought it was even glossier than her areola. Although its lack of pigmentation came from it having never been exposed to the open air, Alfira had no knowledge of anything like that.

Different from her areola, her virgin nipple was absolutely mortifying to her.

The blush on her cheeks deepening further, she couldn't tear her eyes away from her nipple.

To the woman, the thin tentacle approaching her nipple looked awfully similar to a torture implement.

"Stop!!"

The tentacle reached her nipple faster than she could scream.

Even so, it had merely touched her. It wasn't that clear stimulation she'd felt when it had licked her nipple inside her areola.

Yet the sight of her nipple being sucked into the translucent mucus was something she would never have seen living a normal life.

"Huann…!"

A seductive moan came from her mouth.

A stimulation from her right breast jolted her mind. She knew looking wouldn't help, but she slowly turned her gaze towards it. She couldn't stop the wild thoughts spinning through her head now that her restrained body had lost all capacity to resist.

The same as her left breast, a nipple had emerged from the areola on her right. It too was a fresh, glossy color.

And unlike with her left, this one had a thin tentacle coiled around its base. The tentacle was moving exactly the way it had been with her breasts before, this time wringing her nipple.

"A-ah… aah…"

The tentacle put more force into its actions, little by little, bit by bit.

In parallel, the moans coming from Alfira grew louder.

Covered in the slimes' glossy mucus, her pleasure-driven, wriggling upper body was much like a snake. She moved her lower body in the same way, still hidden behind her pair of trousers, her bottom sliding across the hard ground.

However, due to the half-baked way she was sitting, the only pleasure she felt was from the tentacles caressing her upper body and her urethra.

"Dammit, dammi—uuu…"

It wasn't enough.

It couldn't satisfy her.

And even more than that, she was bitter that her body's reactions had become so shameful.

She had forged herself into a knight. She had lived as a knight. She was proud of herself… as a knight.

Yet despite that, having her chest exposed by the monster as it teased her was enough to make her thrust with her hips.

It was unbearable.

Now she shed tears of regret — not pleasure. Even though she knew that crying would help nothing, she couldn't stop herself.

"I don't… want this! No, no no—nooooo!!"

The moment she screamed, she felt something break.

Was it her pride as a knight, built up and reinforced over the years, or her pride as a woman that had thus far been enduring the Black Ooze's torment?

Whichever it was, in time with her voice, her virgin nipples were pulled on, she was licked, her urethra was pried open, and her clitoris was massaged.

Looking up to the heavens, unable to hide her face soiled with drool, snot, and the tentacles' mucus, she was pushed up to another climax.

What did this make the count? She couldn't remember how many times she'd climaxed in this short amount of time. It was uncountable. By now she'd already become incapable of such proper thoughts.

"Fuah, no! Shtahp, o-oow!?"

Her breasts thrust outward as she leaned back, the nipple entwined by the thread-thin tentacle was pulled on, and the nipple being sucked on and rolled around was treated even more forcibly.

Her pose made it look as if the tentacles were suspending her by her breasts. Unable to resist the intense stimulation, the woman screamed.

"Hu-huaaah—!"

And then the stimulation in her lower body increased as well.

The tentacle's activity in her urethra had already turned it into a rather splendid erogenous zone.

Alfira might already have been able to cum just from urinating. The pleasant feeling in her urethra was simply too tremendous.

The paralytic poison's effects had already disappeared completely, yet she still hadn't felt any pain. What would the female knight, a rather serious woman, think of the changes in her body if she realized that?

"Shta, shtaap…"

This woman's body was perfectly prepared to conceive a child.

At least, that's what the Black Ooze had concluded after its experience violating the two mother bodies named Frederica and Satia.

Clink, clink.

Unlike the moans and slimy sounds thus far, it was a metallic sound. It came from Alfira's trousers. Her belt.

Sensing that this sound meant nothing good for her, Alfira weakly shook her head.

She'd already lost the strength to refuse aloud.

Her body was lifted into the air. With her chest, shoulders, abdomen, and knees all raised, she looked like a child being held up to urinate.

"P-please…"

A search party would definitely be sent out to locate and save the missing order of knights.

The knights had announced they were coming to this abandoned mine, so it was a given.

However, how many days would it take for them to finally reach this mine? Rather, how many days would it take for the search party to even form?

… In the meantime, the reality was that she would be violated by this monster continuously. This was not something even Alfira, an experienced knight, could endure.

Being raped by a monster wasn't a situation they were trained to prepare for in the first place. Far from being prepared, no one had even imagined the possibility.

Had it been a human. Had it been a bandit, or perhaps a group of slavers, she might have been able to talk her way out of it.

But this thing raping her was mankind's enemy, a monster. She was all the more afraid for having seen the state Frederica and Satia had been brought to right before her eyes.

Afraid that she would lose her virginity.

Afraid that she would be raped.

Afraid that she would be made to moan.

—Afraid that she would welcome it.

Precisely because there were women welcoming the monsters right before her, her sense of dread felt as though it might become reality whether she willed it or not.

"No, stop, stop it… Fiahh, Fiana-samaaa—"

She begged for help. She moved her body, putting up the bare minimum of resistance.

But her stamina was entirely spent. The mucus restraining the female knight wouldn't be broken by her feeble movements; the Black Ooze couldn't even feel it as an itch.

Her belt was removed as she resisted, followed by her thick pair of trousers.

What appeared beneath was a pair of plain black panties. Since she valued practicality, she'd likely picked the color so that not even a stain would stand out.

Just from her body being pleasured, even her excretory organ had become something she felt pleasure from. Upon taking a closer look at the panties, one would only see a change in color around the crotch.

But those panties concealed a rather tragic state of affairs.

"Stop, stop it—no, sto—"

Looping the tentacle around the side of her panties, it slid them down to her knees.

With that, though not visibly apparent, some liquid other than slime and urine was pulled into a thin string between her crotch and her panties.

Alfira could see what was happening too. Because of her posture, her gaze inevitably fell on her genitals. She was painfully aware of the state of her own genitals. Or at least, she'd thought she was.

But in truth, since Alfira was much wetter than she'd expected, her yet-untrespassed labia had already parted slightly.

"U-uuu…"

She felt shame and hopelessness.

Unable to properly handle the emotions swirling in her mind, she hung her head in shame and began to cry again.

At that same moment, the slime and tentacles that had been stimulating her breasts and urethra stopped moving.

She didn't even wonder whether it had finished. When she thought of how it would humiliate her even more than this, she cried harder.

This wasn't the end. Alfira knew all too well that there was more to come.

After all, wasn't Alfira's future being put on display right before her eyes?

"I'm begging you—"

Alfira's voice leaked out.

The woman's voice was weak.

"—please, stop."

Simultaneously with her mutters, the tentacle stroked her labia.

With a sense of disgust and yet a definite arousal, her hips quivered.

From here on, Alfira would be raped.

It wasn't that large. It wasn't the weapon of mass destruction currently assaulting Frederica, at least. It was even slightly smaller than that of an adult male.

Although Alfira couldn't tell the difference due to her lack of experience, this had been a deliberate choice on the Black Ooze's part.

Pain led to waste in intercourse. It had learned that through its acts with Satia. Furthermore, its implantation into Frederica — who lusted for pleasure — hadn't gone as smoothly as with Satia.

It didn't truly know whether pleasure had any relation to conception in its mother bodies.

However, from anecdotal experience, the Black Ooze had learned that mother bodies submerged in pure pleasure were more easily able to conceive.

"Sh-shta… stop, please…"

The sound of liquids squishing together could be heard as the Black Ooze's mucus and Alfira's secretions mixed.

Rubbing against her labia the way a man might if he were jacking off between her inner thighs, it brushed against her clitoris and made her waist jump.

This was a physiological phenomenon, not Alfira's own intention. Even though she knew that, she felt betrayed by her body's reactions, and even more tears of regret and vexation spilled down her cheeks.

"Stop."

Some strength was put into the tentacle rubbing right against her labia.

Knowing from the feel of it what was about to happen, Alfira bit her lip.

She would at least suppress her voice. Convincing herself of that for the umpteenth time, she once again clung to her failing resistance.

"—"

Her vagina, never before deflowered, was penetrated by the tentacle.

She felt an overwhelming sense of oppression and intimidation.

She couldn't understand why the two were gasping and moaning with cries of pleasure; there had to be something wrong with them.

Alfira hurled abuse at the two before her within her mind. By doing so, she tried to settle herself down.

She cursed that the people with something wrong with them were the two in front of her — Frederica and Satia — and not herself.

She cursed that anything like willingly accepting a monster was impossible.

But the Black Ooze wasn't in a rush as it slowly worked the tension out of Alfira's body. As though it were taking care not to break her hymen, it went back and forth through the entrance of her vagina countless times.

This was the same kind of behavior it had exhibited within her urethra earlier.

Rather than suddenly plunging all the way in, it would gradually, little by little, bit by bit, adapt her body.

"Fu-uhn, nn… nnn—"

The pain she expected never came.

Even that sense of oppression she'd felt at first disappeared before long.

After that, it was like rolling down a slope.

Once the area near her entrance had relaxed, what followed was the slime within her urethra starting to move, pushing and kneading the bladder deep at the end of her urethra and the root that could be called the backside of her clitoris.

Her empty bladder no longer cried out in pain, instead conveying a pleasant sensation no human had ever felt before.

It was the same with her clitoris. How would any human ever have felt their clitoris stimulated from behind it?

Similarly with her glossy nipples, her right one was pulled on by the string-like tentacle and teased.

Her left nipple was licked, rolled, and entirely visible through the transparent mucus.

She felt as though richly colored fireworks were going off inside her head.

Her eyes looked towards the rocky surface of the walls but saw nothing, simply shedding tears. The lips she'd been biting down on had parted slightly, her glossy tongue and beautifully white teeth peeking through.

"St… op…"

Her body slackened.

She couldn't put any strength into it at all.

Still suspended by the Black Ooze, Alfira had grown so weak she could no longer even resist with her voice.

The Black Ooze, having acquired the techniques and knowledge of dozens of men, was much too skilled in pleasuring Alfira, who had barely even known about these acts.

Each time her nipples, clitoris, urethra, or vagina were stimulated, the female knight's body would react in amusing ways.

She looked just like a toy given to some child — a child named Black Ooze.

"Fuah—ahnnn, uu…"

The toy swallowed her saliva.

Each time the toy was stimulated, she let out a moan, reacting to even the slightest touch. The way she flickered back and forth between pleasure and resistance was amusing.

"Ha-aah. Nnuu—sho, go-ood…"

"Go, shu… shamaaaa…"

Frederica and Satia were the first to collapse.

It was only natural, given they had started being ravished long before Alfira woke up, but the state of those two was wretched.

Their bodies were entirely covered in mucus, their rich hair clinging to body and cheek alike.

Above all, the amount of cloudy white liquid — distinct from the slime's mucus — spilling from their labia was abnormal.

The semen that had no room left inside them overflowed, trailing down their thighs.

Alfira didn't know what kind of thing a monster's semen was. However, what she did know was that a human would definitely be impregnated if that much was poured into them.

The duo's expressions — they looked incredibly pleased, delighted, and satisfied… Most of all, both of them took the tentacles brought near their faces into their mouths without hesitation, twined their tongues around them, hollowed their cheeks to suck, and serviced them with faces too unbearable to look at.

(… Ah.)

Would she become like that as well?

(Aaah…)

Would she also wish to willingly please these monsters?

"A-ah—hiiiin!"

Another tentacle began to knead her clitoris.

While cursing the fact that her body would climax from that alone—

She felt fear, humiliation, shame, and pleasure. Each of those feelings, and each of the various fluids covering her, warped her expression.

"Get, aw—… get away, from meeee!!"

Shlink.

Alfira felt like she heard the sound of something tearing.
