Inside the Cave of Obscenity

Chapter Volume 4 2: Monster 2

"Release me, let me go!"

Inside a dimly lit, ramshackle building with only a modest layer of straw on the floor like that of a cattle shed.

There were few windows, but the room was poorly ventilated, and the air was stagnant, there were several iron shackles on the walls, probably to restrain someone.

In the corner of the hut, a woman in a glittering costume, her limbs bound by the eerily moving filth, was scrambling to escape.

"Damn it! How could the slime even come here!?"

The woman's voice was filled with disgust, but not fear, even though she was covered in a vile, wriggling mucus.

In fact, she could even afford to look down on the slime as something lowly and argue with it forcefully.

She had long dark red hair and a voluptuous body.

The woman's appearance was very human-like, but the tears in the corners of her long, slit eyes, which showed her strong personality, were about to spill out, indicating that the strong words she was saying were only on the surface.

The woman was well aware of the existence that was surrounding her.

Perhaps even more than the hostile humans.

"You. Why are you attacking your allies, you sex maniac slime!!"

She had small wings on her back, like that of a bat that did not exist in humans, and a long, thin, fairy-tale-like devilish tail sprouting from her hips near her anus.

The woman was also a monster, same as the lump of mucus that was clinging to her.

A succubus.

A female monster that sucked the lifeforce and mana out of men.

They were not very powerful, but they have a variety of special abilities, such as hypnosis, seduction, and in the case of high-ranking succubus, they could interfere with other people's dreams, violate men in their dreams, and suck out their life force in ways that most human mages would never think of.

It was a monster that was born using the demon king's mana during the time when the demon king existed, just like the slime, but now it was being attacked by the slime, which could be said to be its own kind.

The fact that it was a member of her own kind, did not confuse the succubus woman, though she was surprised.

"Hey, you attacked the village we got and killed all the men. You should have thought about your surroundings a little bit―― wait!? Still talking―― kyaa!?"

Succubus―― As they were called female monsters, the clothes she wore were highly revealing.

Her twin breasts were as lush as a large piece of fruit, and her waist was so tight that it looked like it could snap if one put enough pressure on it.

She had a supple, well-trained back that could charm a man with just from her rear view, and a well-fleshed ass.

A black stocking adorned her long, slender legs, while a thin leotard-like cloth hid her body.

She wore a red and white dress-like outfit with a large opening at the chest area, giving one the impression of a high-class woman.

The leotard-like thin cloth was the unique attire of a succubus, and the red and white dress was taken from a human residence.

The slime entered through the bosom of her dress and licked away the sweat that had accumulated in the deep cleavage of her breasts.

It felt as though a long, thick tongue was licking her, and the woman let out a cute, uncharacteristic scream.

"Wai-!? Stupid, don't lick that place!?"

One could still hear the courage in her voice as she complained.

The reason why she didn't feel so bad about it was because they were both monsters, even though they were of a different race.

In the past, the demon king was also created from mana, and although he was angry at his monsters, he was not as hostile or deadly to them......

"You, you can't do this to me―― I'll never forgive you!"

Because of their human-like appearance, many succubi lived among humans.

They were created to suck the lifeforce out of people and thus cause chaos in human society, but after the demon king was defeated, they lost their will to fight, but could not change their way of life and had to live among humans.

Fonteau, where there were many mages, was a good feeding ground for them, and they could go from village to village disguised as human women, or work as beautiful prostitutes in the brothels of the royal capital.

The succubus Fenelieka, whose limbs were restrained by sticky mucus and whose beautiful dress was being stained, was one of these female succubus.

She was the third most popular prostitute in the brothel in the royal capital of Fonteau, where she worked every night to make a living and a lot of money from men.

――Incidentally, the first and second were also succubus.

When the country was destroyed by the slime, Fenelieka escaped from the royal capital with the humans and joined other succubi to attack the neighboring villages.

The chaos caused by the slime activated the monsters that had been chased out of their homes by adventurers, and it was becoming an opportunity for not only succubus but also lower-ranking monsters such as goblins and orcs, as well as higher-ranking monsters that were on the verge of being destroyed as a threat to humanity, to survive......

The problem was that the slime that had attacked the human race in Fonteau had now turned on the monsters.

First, the goblin settlement was attacked.

Then the Orcs, and then the Kobolds, who had been attacking villages and posing a threat as monsters thanks to the slime's disruption of the country, but now they were eradicated by the slime.

Yes, eradicated.

Every single village occupied by the monsters was destroyed or absorbed by the slimes, and the surviving women were all violated.

And this time, it was the village of succubus.

A village of a dozen or so succubus, led by Ariade, the most popular succubus in Fonteau's brothel.

Because it wasn't that big, the men who lived in the rural village were able to make a good living.

Fenelieka was also a succubus living in the village and had a reasonably high position.

She collected precious metals and other fine ornaments and clothing that other monsters wouldn't pay attention to, adorned herself with them, and charmed men to gather a lot of energy.

However, such a happy time came to an abrupt end.

"If you want to attack, it should be Ariade and the others!? E-even if you attack me, nothing will happen!?"

It was daytime.

The first thing that happened was that the gatekeeper, a useless sleepyhead who had done very little work, was attacked.

Literally, she was attacked and violated by the slime. She was violated, but she wasn't killed like the other monsters.

The slime took the succubus it violated into its body, restrained her, and continued violating her, only letting her face out of the mucus so that she would not die.

The succubus, who was sexually uninhibited and should have been far superior to the humans in that field, was given such pleasure that she cried out for forgiveness and was still being violated.

Less than half a day later, the slimes captured the village, and most of the dozen or so succubus were caught.

Now that they've been captured, Fenelieka heard the high-pitched screams of her companions' climaxes from afar.

The sobbing voices of those who could no longer bear the intensity of the pleasure being given.

She could hear the voices of those who were resisting and spitting violent words.

And Fenelieka, who was hiding in the shed that was originally meant to hold the captured men for food, was also spitting violent words on the slime.

Succubus and slime were indeed both monsters, but there was a significant difference in terms of strength.

Monsters were a race with an established hierarchy.

The strong were the superior ones while the weak obey their orders. That position was absolute.

The slime was the lowest of them all, equal to the goblins, while the succubus, who speaks words, had a higher position than the slimes. The slimes were supposed to be obedient to the succubus' orders.

"Why don't you listen to me, you idiot, pervert. Don't get inside my clothes!?"

She was desperately trying to pull off from the mucus, but finally, the slime got inside her dress and started licking and sucking her tits and armpits.

It was licking the sweat that had accumulated there.

Realizing that, a blush appeared on her cheeks for a different reason than her anger. No one would feel good about having their sweat licked.

"No!? S-stop, it tickled..."

And with just that, Fenelieka's shoulders jerked and her arms, which had been struggling to resist, slowed down.

Fenelieka was weak in her armpits.

The men who were attracted to the beauty of the succubus were caught up in the act of intercourse, not in a place that should not be stimulated.

She felt as much, if not more than, from there than the breasts and pubic region of a woman.

The slime may not have known that, but it was able to find Fenelieka's weak spot in a short period of time, and licked and sucked her with more relentlessness than human men.

"No, ah, ahn... stop."

It was not long before her breath became hot and her arms and legs relaxed.

As she flailed, her long skirt rolled up, revealing even the slightest peek of white skin between her stockings and the fabric of her leotard.

With no time to correct her disarrayed clothing, Fenelieka writhed on a simple straw bed.

Perhaps it was because she was a sexually uninhibited succubus. The instinct that it didn't matter who it was, as long as they could give her pleasure, worked in the wrong direction.UppTodated from

"Haah, haah... I'm weak, there... mou, stop it..."

The slime could not hear her, even though she appealed to it with tears in her eyes.

Rather, the stimulation caused her sweat to appear all over her body, which could only be an advantage for the slime that absorbed mana from bodily fluids.

"Ah, lie... n-no."

The slime lifted up Fenelieka's arms and used the iron shackles to hold the livestock―― human men in place and restrained her.

She was surprised that the slime would use human tools, but the time to think about that quickly disappeared.

The mucus that had entered her breasts now penetrated her leotard and began to stimulate her breasts while she was still clothed.

"Mou! What the hell. What the hell is this slime!"

Fenelieka writhed on the straw bed while swearing.

Her ample breasts were squeezed through the black leather textured leotard, causing her big tits to change their shape obscenely while she was clothed.

It really showed how roughly the tentacles on her clothes were playing with her twin breasts, and even with such rough treatment, Fenelieka's breathing was getting hotter with each passing moment.

"Fuu, hauu... stop it already..."

Her body was lying on a straw bed, with only her arms bound to the iron shackles on the wall.

Fenelieka's hips quivered a little in the mucus.

It was a shallow climax.

It was the pleasure that she had finally reached.

"Nhh... you."

Fenelieka swore.

It was not enough. It was not the same as a violent sexual intercourse climax, it was as frustrating as masturbating on her chest or armpits.

It felt good, but she could feel the heat building up in the back of her waist.

Deep inside her black leotard, her love juices ooze out, and the slime sucked them up. It was the best food, with much more mana than it got from sweat.

"This, guy... my mana..."

For monsters, such as goblins and orcs, eating flesh was a way to obtain mana.

For Succubus, intercourse was a way to gain mana.

For the slime, intercourse was a way to absorb mana similar to a succubus.

"Hyuu, nhh... kuh――"

The slime's movements change.

Suddenly, without reservation, the movement of the mucus clinging to Fenelieka's chest changed.

It picked up the entire nipple and pull it over her clothes.

In the mucus that enveloped her entire body, her beautiful, shapely breasts were pulled and her nipples were lifted like a tip of a spear.

"I-it hurts......?"

Even though she had been roughly handled to the point where she would normally feel pain, Fenelieka's entire body was shaking in the mucus. She was convulsing.

(Why...? It feels good...!?)

"Nhh, guh... higuu!"

She shuddered from the shoulders up.

The sudden stimulation from her climax caused her to turn up her shapely throat, and her beautiful face turned to her wrists, which were bound by iron shackles above her head.

But her eyes weren't looking at the iron shackles.

(I, climaxed...?)

She had never experienced such an easy climax, even with a human. And it was only with her armpits and breasts, even though they were her weak points.

Her nipples tingled from the rough tugging.

As the mucus released her nipples, her breasts returned to their original shape, and the tingling in the depths of her flesh seemed to intensify just from the stimulation.

"Hyuu!? Nhh, haa!? Nghh, nhh!?"

(That's!? Suddenly!?)

This time, it was rough from the start.

Her beautiful large tits were roughly squeezed, pulled, squashed, and squeezed in the mucus.

The bosom of her dress slipped off, and her leotard-wrapped breasts were completely exposed.

When the leotard was pulled to the center, the breasts as white as fresh snow, which had been held in place by the leotard, spilled out with a loud noise.

Even through her leotard, her large tits were stunning, but now that it was free from the restraints of her clothes, her tits were shaking so violently that they almost make a violent sound as though they were happy to be released.

"Wai-, you――!?"

Fenelieka choked on her words, her eyes black with dismay of having her clothes removed.

It was the tip of her breast that was exposed to the mucus.

Her nipples were so hard and pointed, and even her areolas were swollen with excitement.

She was speechless at the sight of her breasts, obscenely swaying in the dirty mucus.

"It's a lie, mou!? Stop it already, stop it, y―― hyuu!?"

The mucus was so rough on her exposed breasts that the word "humiliation" seemed appropriate.

Fenerieka writhed in the corner of the shed with her head turned upward, the only part of her body that was not restrained.

It was as though she was being squeezed by a myriad of tiny hands and mouths with her huge breasts that could not even fit in a man's two hands.

Her entire breast was being squeezed, her areola licked, and her nipple bit.

It was asymmetrical: if her right breast was licked, her left breast was bitten, and if her left breast was squeezed, her right breast was pulled.

Her breasts were literally handled and reshaped in the mucus as though they were "toys".

The same goes for her armpits.

They were licked, sucked, rubbed, and tickled.......

"Nhaaahh!? Nnh, nhhhhh!?"

Turning her head up again, Fenelieka climaxed.

Her neck was covered in sweat from the mucus, and her eyebrows as well as the corners of her eyes were lowered in a "C" shape to show the extent of her pleasure.

Her skin, which had been as white as fresh snow, was now reddening all over her body, especially her face, which was now so red up to her ears that she looked like she was about to run out of oxygen.

"You. Suck my mana, so get it over with......"

Drool spilled out from between her clenched teeth and sparks crackle behind her eyes.

The succubus was terrified of the slime for the first time as she realized that her breasts and armpits alone were giving her pleasure and that she was impossibly hot inside her waist.

"Ahhhhh, kuh, hyuu..."

She spurted out her love juice from deep within her hot and raging hips.

She understood that there was a source of mana inside there, but the slime would not enter it.

Fenelieka also couldn't ask it to make her feel better because her pride as a succubus got in the way.

Only time goes by.

For Fenelieka, the humiliation of having made to moan by the slime while caressing only her breasts and armpits was unbearable.

For the slime, it was nothing, just to make its prey moan.

The difference in temperature was fatal.

At any rate, the slime was not holding anything back. It could continue to rub Fenerieka for minutes, hours, days, until the succubus, the most well-known of all sexual demons, gave in, even until her breasts broke.

It was not about patience or guts.

It was just that kind of creature. It was a living thing.

"Naaahh... ahh!?"

How much time had passed since then?

The screams of the lecherous demons from the surrounding area turned into gasps, and of course the voice of Ariade, the head succubus, mixed in.

Even the sexually uninhibited succubus was no match for the inexhaustible supply of energy that was endlessly giving them pleasure.

Rather than absorbing their life force, it absorbed their mana, so it was no wonder.

"Ah, ahh... h-help..."

Still, Fenelieka was not broken.

Even though her body had become so sensitive that she climaxed just by having her breasts squeezed, squirted just by having her nipples pulled, and trembled all over just by having her armpits licked and sucked, she still wasn't penetrated.

She knew that if that happened, she would never be able to escape from the slime.

She knew that if her breasts and armpits alone made her feel so good, it would literally be the "end" of her if her womb fell as well.

"Hahi, hii..."

After some more time passed, Fenelieka's throat became hoarse from moaning too much, and she repeatedly breathed weakly.

Her purple hair, wet with sweat and mucus, clung to her face like a maiden who had been humiliated, but there was a certain joy in her expression.

The fact that her dress and leotard were still intact, but only her breasts were exposed, was the result of Fenelieka's continued resistance and pride.

The cheering from her peers had died down, and the sunlight streaming in through the window was a brand new early morning light.

Overnight, Fenerieka had her breasts squeezed, her armpits licked, and her entire body caressed.

She didn't know how many times she climaxed.

Her eyes were blank and her mouth was foaming as well as drooling.

Her breasts were overly sensitive to the point that it was painful, and her nipples were glistening in the mucus.

......Her nipples, which had grown to the size of the tips of her little finger, were bent at the base.

"Haah, hii――!?"

That was it.

She wasn't rubbed in her chest, caressed her entire body, and of course, she wasn't teased on her genitals.

The only thing it did was bend her nipples from the base, and the succubus let out a muffled cry and trembled weakly all over her body.

The mucus-covered crotch spurted out a vigorous squirt that was quickly absorbed by the slime.

When Fenelieka, who was made to climax dozens and dozens of times in one night, almost broke her pride as a succubus.......

"――Please wait!!"

......After those words, Fenerieka completely lost consciousness.
