Inside the Cave of Obscenity

"Haahー, hahhー......"

The breathing due to weariness echoed in the darkness.

The owner of the sound - a small fairy - was still being violated by the slime in the depths of the ruins that had collapsed and its internal structure changed.

She was as small as a doll, with white skin that had never got sunburned.

Her slender hands were stretched out, bound in a "大" figure. Covered in filthy mucus...... Her hair, which was once a beautiful golden color, was stuck to her cheeks, and her expression showed no signs of playfulness or liveliness.

The neat dress she was wearing had turned to rags and only covered her shoulders and waist, leaving most of her skin exposed.

The underwear was on her left ankle, and every time a tentacle entered her vagina and moved back and forth, her thin, supple, beautiful legs twitch and jerk.

She was still alive.

Alive, but she had lost the will to escape―― just like her appearance, she was treated like a doll, with her unrestrained legs and feeble head shaking in time with the thrust of the tentacle.

"Uh, ah..."

(Is it, daytime... nighttime now?)

Fairies were lively, cheerful, and innocent beings. They were full of curiosity, and their lovely appearance made them loved by everyone.

They were about the size of a human's palm and have beautiful butterfly-like wings on their backs.

That was the identity of the woman who was being held captive by the slime.

The fairy, who would normally bring happiness with a lively smile on her face, had a look of fatigue on her face, and her eyes were just staring at the stone ceiling.

The slime was sticking on the wall, and the fairy was trapped in it looked like a butterfly that has been made into a specimen.

Her beautiful wings were stained with mucus, and it had been days since she had last flown but she might not be able to fly again.

Above all, it was the unnaturally swollen abdomen that was depriving her of her energy.

Pregnancy.

――Originally, they were born from nature, incarnated with the world's mana, and when they die, they return to the world as mana...... So the fairy would never have children.

However, the fairy's abdomen swelled while trapped in the slime's mucus, and the fairy herself knew that it was due to something other than the Black Ooze's semen.

Compared to her small body, her ample breasts were filled with two slimes that moved differently from the slime that bound her body.

They were stimulating her nipples, as though they were children seeking their mother's milk.

From her breast, which she supposedly would not get pregnant―― and of course not produce breast milk―― produced milk and sucked up a large amount of mana in it.

......It was her children, the ones the fairy had given birth to in the past few days.

"Help... me..."

The fairy muttered to the darkness of the empty ruins.

Her legs trembled and her thin, supple white fingers moved as though trying to grasp something at the empty space.

Even though the fairy was on the verge of losing her will to live, the movement of the tentacles had not stopped.

Even now, the thin tentacle that fit the fairy's small body was making a wet sound as it entered her vagina.

Rather, it may be making the sound on purpose so that the fairy could hear it.

Ever since the fairy was captured. Morning, noon, and night, whether she was conscious or not, and her intentions were irrelevant.

She climaxed, ejaculated in, and gave birth to a child. That was the only reason for its actions.

The slime, the Black Ooze... its instincts.

To have children, to increase its own kind, and to become stronger by absorbing the food called mana. Just for that.

"Uu...... uuu..."

Tremble*.

Her limbs trembled. Her voice leaked out on its own.

Her vagina produced love juice to protect her body, and the tentacle inside her vagina absorbed the love juice and repeated its thrusts more forcefully.

The child slime sucking on her breasts had also inherited the Black Ooze's knowledge and was learning how to caress the fairy.

Even though they were born only a few days ago, It sucked, rolled, and rubbed her hard nipples and also stimulated the inside of her breasts by invading its mammary glands.

The tingling stimulation accumulated inside her nipples, and the accumulated mana was sucked out.

Once the mammary glands were invaded, they loosened up, and once a little mana had built up, they were sucked easily.

And the child slime grew again, just a little bit.

A being born from nature and using the mana from the world. Fairies.

The amount of mana they have was much larger than that of the elves, who were good at magic, and the child slime needed more mana than the Black Ooze to grow more.

The mutant Black Ooze could grow limitless as long as it ate and taken in something.

And this slime was a Black Ooze that specialized in magical warfare.

"Haah, haah, haah――"

The fairy's waist trembled greatly.

Her mouth was wide open and drool was dripping down her face.

Her body was as small as a doll, but her legs were feminine and plump. When the drool fell on her ample breasts, the child slime licked it up along with her sweat and her milk that continued to overflow.

For the slime, the bodily fluids from humans, elves, and fairies imbued with mana were all food.

The slime licked, scooped up, and absorbed every drop without missing a fluid.

Fonteau, the land of the elves. In the country where the hero's wife lived, it had taken in thousands, if not tens of thousands of elves.

The mana possessed by the Black Ooze was already beyond human comprehension. It was not an exaggeration to say that it was probably the strongest in the continent consisting of three countries.

Still, this being was not satisfied and was trying to absorb more mana even from just one fairy.

Greed.

Its desire could not be satisfied by a single country, but rather the consciousness of the elves and humans who it had taken in was growing, mixing with its monster's instincts, and it may be turning into a completely unknown existence......

"Fuu... nhh――"

The fairy turned her head up slightly. As she looked up at the ceiling, her body trembled and climaxed without the energy to make a charming sound.

"Haah, haah――"

Her small body trembled quietly but her well-formed, rich breasts swayed violently.

Her long hair hid her expression, but her small body continued to tremble.

The tentacle that had entered her vagina had not stopped moving.

The innermost part of her vagina, the entrance to her womb that had been tightly closed a few days ago, had already been invaded and was now only tightening slightly.

As the mucus tentacle penetrated further into her open womb's entrance, to the back of her womb, it moved and stirred up the semen that had accumulated inside, stimulating the very small womb as much from the small fairy's body.

The sharp pleasure that seemed to pierce her brain penetrated through her body, the back of her belly button, and the depths of her hips―― places that should not normally be stimulated, and the fairy let out an inaudible scream.

A vigorous squirt erupted from her urethra, and when that happened, a thread-thin tentacle invaded it, and suck up all the fluid that had accumulated in her bladder.

"Igii―― hii, ahhh!?"

She screamed in a weakened voice.

The unrestrained part of her body trembled violently.

The stimulation of being forced to stop the liquid that was supposed to spurt out was too stimulating to be called a pleasant sensation, and the pain was so strong that the fairy, who was in a daze from exhaustion, woke up forcibly.

The fairy tried desperately to escape the pain by shaking her hips to get away from the tentacle in her urethra, but in fact, the shaking of her hips stimulated her urethra even more.

(It hurts!? It hurts, it hurts, it hurts!?)

The pain made her move her hips, and moving her hips made the pain worse.

It had been repeated many times over and over...... every time the fairy recovered.

Even though in her mind she understood that there was no point in doing it, her body would certainly react in rejection to it when both her legs were unrestrained and could resist.

In fact, the slime seemed to enjoy seeing her "gesture" as she resisted.

It was as though it was getting relief from the horrible things it was doing.

(Help... it's too painful...)

She couldn't breathe. Experiencing climax after climax. She was feeling pain and fear.

Her chest tightened, her throat was choking, and the turmoil was making her forget how to breathe for a moment.

The fairy had been forced to instill it in her mind. Over the past few days, it had been ingrained in her body.

――If I resist, I will suffer.

――If my mana recovered, I will be tormented.

――I'm powerless......

She climaxed and climaxed and climaxed.

Her mind became hazy, her breathing became rough, but still, the tentacles did not stop moving.

Her beautiful eyes were hidden behind her eyelids, and it was rolling back, but her fear was getting stronger in the corner of her mind.

――Tears overflowed from the eyes peeking through the gaps in her long hair, as she realized that it was where the real pain would begin.

Then the fairy's premonition came true.

"――! ――!!"

Shiver*. Her body convulsed. Twice, three times... four times.

The shaking grew stronger with each climax, and an inaudible scream escaped from her glossy lips.

She was sweating as though she was suffering from a fever, and her convulsions became more intense and shorter.

(Help……)

"Help... someone..."

The fairy muttered in desperation while tears rolled down her face.

Her muttering was swallowed up in the ruin's darkness and reached no one.

She climaxed over and over―― the fairy did not even realize that some of it was her climax―― her face turned red from lack of oxygen, and she began to lose consciousness.

――Even so, the tentacles did not stop moving.

She desperately inhaled to take in oxygen, but the tentacles thrust caused her to blow out the precious oxygen.

Her ample breasts swell and sink repeatedly.

All over her body. She was feeling the sensation of her mana spilling out from every hole in her body.

The feeling of exhaustion―― of letting go of not only her consciousness but also her soul, she was feeling fear that it would threaten her life.

"Hii, hii, hii!?"

With her mind anticipating her death, her body greedily and repeatedly climaxing.

As she was poked again and again, and again, and again at the weak points in her vagina that had been laid bare over the past few days――

"Bufu!?"

Her nose, which was desperately trying to take in oxygen, blew snot vigorously and ungracefully.

It was distorting her doll-like good looks, but she had no time to worry about that.

The same goes for her drool, sweat, and tears.

The fairy climaxed, as her beauty was stained by the overflowing body fluids.

Her small, doll-like body spasmed repeatedly like a broken toy. Before she knew it, the fairy had let go of her consciousness, her eyes were blank, and she was just bobbing her head up and down in time with her spasms.

Sweat and tears flew through the air as she moved, and the slime on the wall stretched out its tentacles like a snake to take in her fluids.

Both of her legs, which were thrown up in the air, stretched out.

Her toes curled up, and her tense hips twitched and jerked in small spasms.

Even though she lost consciousness, she kept climaxing. Clearly, she was not out of that suffering.

Unconsciously, the fairy's beautiful limbs were forced to ascend to the heights of climax, and her unnaturally swollen abdomen wriggled eerily.......

"Is it, here?"

Crumble*. The rubble from the ceiling of the ruins blocking one corner of the passage collapsed.

A sharp, crisp voice echoed in the space where there was no sound except for the fairy's charming voice.

It was a girl's voice.

In fact, what appeared from the other side of the rubble was a petite girl―― an adventurer who was still somewhat young, but possessed the courage not to be surprised by the sight of a monster called slime.

A female adventurer dressed in a black robe, swaying her long silver hair on the left side, walked down a slime-covered floor and walked to the fairy who was twitching.

"You want this child, isn't it? Alfred-sama."

Silver hair and brown skin. In her hand, she held a staff as tall as she was, and on her left shoulder, there was a small, really small slime.

The adventurer mage called out the slime. Alfred.

"Hey, Satia! Mou, help me clean up the rubble, please."

"Sorry, Frederica-san. Alfred-sama wants to move on quickly..."

The silver-haired mage known as Satia said to the blonde woman who was lifting the debris using magic to create a way for her.

The woman known as Frederica was wearing a black undershirt, heavy pants, a triangular hat, and a long cloak, the kind of outfit that anyone would recognize as a mage.

There was also a large staff on her back, not so different from Satia's.

Frederica scratched her cheek with her fingers and looked around.

"So this is your new nest huh."

"Yes, a new "house "."

At those words, Frederica let out a small sigh.

Slime―― Black Ooze.

Satia, the silver-haired mage who claimed that her master was the monster in front of her...... the enemy of mankind that she completely accepted.

Alfred was the name of her former master.

......He, too, was absorbed by the Black Ooze.

Satia loved him, but after being killed, swallowed, and absorbed right in front of her eyes, she went insane, and to keep her mind from breaking completely, she was treating the Black Ooze his master, Alfred.

Frederica, who was with her, was the Black Ooze's first prey.

It was the mage who has been raped for days, weeks―― just like the fairy who was trapped in front of them right now―― and had been "subdued" in both body and soul.

Both were excellent mages.

Frederica was here because she realized that she would never be able to 'win' against the Black Ooze. After all, she only had skills and mana comparable to the elves who specialize in magic.

If she stayed with it, it would fuck her.

And it would make her feel good.

It didn't matter how many hours, how many days, how many mornings, how many nights―― even if she passed out, it would not stop, it would give her such pleasures that she felt like she would die.

That was why Frederica was working for the Black Ooze and cooperating with Satia.

"Poor thing."

Frederica said as she looked at the fairy who was being raped even though she passed out.

Her words of pity came from the certainty that the fairy would realize the word "defeat" imprinted in her mind, just as she had.

The humiliation of being raped by a slime.

The despair of having one's mind subdued by an enemy of humanity.

――And the awareness that she had been transformed into a thing that could no longer be satisfied by anyone.

It would be engraved in her.

In the depths of her body. In her core...... no, in her soul.

"Nghh."

Frederica let out a hot sigh as she watched the fairy being raped.

Heat lit up in her depths, and unconsciously, she rubbed her legs together, which were wrapped by her pants.

She had always been sexually unreserved, but now, even more than before, Frederica was vulnerable to pleasure.

Her breasts, wrapped in a thin black undergarment, were as large as small fruit, with its small bulge was getting erect.

Her breasts and abdomen were producing sweat, and her slightly unruly breath added to her sex appeal.

After seeing the collapse of the elven country of Fonteau with their own eyes, they traveled with the refugees to the beastmen country of Grabalt and headed for the temple while hiding from the hero's daughters.

All for the sake of the Black Ooze.

The Black Ooze, which had taken in countless humans and demi-humans, had a kind of will and showed it in its actions.

What made it possible was magic.

Humans and elves only use magic for destruction, but the Black Ooze, which had taken in the will of many, could communicate their will through magic, not words.

Maybe there was an individual or two who had been studying such magic among the thousands or tens of thousands of humans it had taken in.

Or perhaps, because it was a mutant species that had unconsciously made completely new magic―― neither of them knew.

The thing they didn't know was why the Black Ooze had expressed its will through magic. The reason for that was immediately clear.

Fairies―― a race different from humans, elves, and beastmen like Frederica and the others―― that used mana from the world.

A completely new ability.

The Black Ooze on Satia's shoulder extended its tentacles.

The slime that was sucking the milk and mana from the unconscious fairy's chest also extended its tentacles.

It was only for a moment.

The tentacles that touched each other intertwined, fused, and became one.

"You've become stronger again, Alfred-sama."

Satia crouched down in front of the fairy as she was being raped, her voice was quiet but full of joy and excitement.

She held up her pinky finger and stroked the fairy's pubic area.

"Nghh..."

"So, is Alfred-sama's child inside?"

With the nail of her little finger, she rubbed her bare clitoris.

The reddened and swollen clitoris due to her being raped nonstop had grown larger than its original size, so large that even Satia's pinky finger could touch it.

When she gently stimulated her clitoris with her fingernails, her small body trembled again and again like a doll.

"She was so sensitive that she could climax with just this. Alfred-sama's mother."

That statement was faulty, Frederica thought.

She still adored and respected the young man named Alfred―― but she acknowledged all of the countless Black Ooze as "Alfred" and the slime that would soon be born was also "Alfred" to her.

It was not faulty, but rather a complete mental collapse.

However, since she still had her reason and intellect, the sight of her "playing" with the body of the fairy like that made her look insane.

"Here, here, isn't it? Come on, Alfred-sama. Please come out."

Satia said that in a voice that still didn't show much emotion, and slowly, gently, but forcefully, buried her little finger into the fairy's vagina.

For a fairy with a body as small as a doll's, even Satia's petite little finger was as hard and thick as extra-thick manhood.

Her abdomen, which had been unnaturally swollen, deformed, and her face, which had been unconscious, looked up at the ceiling.

"Oh, oooh!? Hii, gii―― wh, at!?"

She was forcibly awakened.

It was different from the slime's tentacles. The fairy regained consciousness at the touch from a thick, hard object that was not thin enough to fit in the fairy's body.

When her gaze settled in front of her, and before she knew it, there was a human being in front of her.

Her action was quick.

"H-help―― help me. Help me!!"

She said in a hushed voice, but the two humans did not move.

In fact, when the fairy realized that the pressure she was feeling in her vagina was caused by one of them, her beautiful face became distorted with fear.

"What, why, why!?"

"Please give birth to Alfred-sama's child soon. In this way, I'll make the hole bigger so it's easier to come out."

"What are you, what are you doing!? Stop, it hurts, it hurts so much!"

The fairy asked for help from the other woman, Frederica.

Frederica, looking at the fairy as she asked for help...... she also asked for help in that way before too, but still, no one came, and she was raped over and over again and was made to cum―― as she remembered that. Her breathing became erratic, and her underwear, under her pants was starting to get wet.

Her eyes overlap with the fairy's and was informing her something other than words.

I envy you.

"Hiii."

The fairy screamed.

She could intuitively understand that these two people in human form were not normal......

"Help, me……"

The fairy said that as her entire body trembled from being violated by the human's little finger.

Even though she knew that her wish would never come true, she had no choice but to say it.

It was the only hope that kept the fairy's "sanity" intact.

She wondered how much time had passed since then.

Frederica, who was sitting in the corner, pulled out her right hand, which had been thrust inside her pants.

Her fingertips were wet with her lewd juices, and the feel of her damp underwear was unpleasant. As her sweat-soaked underwear and cloak clung to her skin, she felt a comfortable exhaustion wash over her.

She was masturbating.

There were many slimes. While surrounded by creatures who would rape women, but without being raped, only watching...... and masturbating while someone was being raped was not bad.

She awakened a new sexual inclination.

"Satia...?"

As the slime beside her licked and sucked at the lewd fluid on her fingers, Frederica called out her name.

"See, just a little more. Please do your best."

"Forgive. Forgive me, forgive me already!? It'll spread out, It'll never be able to get back to normal!"

The fairy's high-pitched voice, unthinkable from her initial lethargic state, echoed in the passage.

Satia was still expanding the fairy's vagina with her little finger.

Her vaginal canal was widening, allowing the slime that had grown in her womb to come out easily, but Satia's fingers were getting in the way of its birth.

"Let me put it out, let me put it out!! I'll give birth, so I'll do anything. Please, pleaaase!!"

"Do your best. Please do your best."

While listening to the fairy's desperate plea, Satia said the words without any emotion in her voice.

Frederica understood why.

For the Black Ooze, which absorbed mana from a woman's bodily fluids, the inside of the womb was the perfect feeding ground.

Stimulating her vagina and letting the slime child absorb the overflowing love juices from her vagina to give birth to an even more powerful child...... was it human sanity or slime-manipulated madness?

She didn't know which one it was―― Frederica felt the back of her womb getting hotter again as she listened to Satia's words and the fairy's scream.

She couldn't stand it, so she would masturbate again, but as her fingers almost reached out to her lower body again.

Her fingertips were covered with slime.

She wondered how good would it feel if she pushed it into her womb―― if it absorbed the mana in her womb, get bigger, and went wild?

With that in mind, gulp*, Frederica swallowed her saliva.

"Nhh, nghhh."

As she stimulated her vagina with the slime on her finger and pushed it to the very back of her vagina―― near her womb, which was filled with the Black Ooze's seed―― she let out a hot breath that almost set her on fire.

It was as though the semen inside her womb was raging as though it had a will of its own, stimulating her entire womb.

In search of mana inside, she could feel that the slime that she pushed into her womb was going further in that her fingers could not reach.

Frederica stood up, shaking her hips at the sensation of a foreign object climbing up her womb.

(Feel so good.)

Her feet tremble from the stimulation of the slime moving inside her body, and she stomped her feet on the ground.

Cutlet, cutlet*. Unconsciously, her leather boots kicked a pebble that was lying on the floor.

"Well then, Satia. I'm going first."

"Yes. If this child gave birth to a lot of children, I will follow."

"……Alright."

The expression on Satia's face as she looked back was the very girl that Frederica knew.

There was no madness there... so she could feel a chill run down her spine.

Satia's fingers aren't stopping.

That little finger penetrated the fairy's vagina, scraping her vaginal walls with the tip of its hard nails so as not to damage it, and giving endless pleasure.

"Wait, wait!? Please, help me! Please!!"

The fairy desperately called out to Frederica for help.

She was a woman cooperating with Satia, who was torturing her, but Frederica still had reason in her eyes.

"Frederica-san. Please take care of Alfred-sama for me."

――But it was the same for her, Frederica thought.

She put the slime in her womb of her own volition and walked away...... without even looking sideways at the cries for help as she felt the pleasure from the stimulation that almost made her back fall out.
