Inside the Cave of Obscenity

(Don't come――Don't come.)

Late at night, on the third floor of the research tower in total darkness, Alp muttered it over and over in her mind as she curled up at the desk.

Her mucus-soaked black innerwear glistened wetly in the little moonlight streaming in through the window, and she could see the movement of tiny, thumb-sized slime crawling beneath the thin fabric.

Was it intentional or just instinct?

A few of the slimes crawling under her innerwear aimed at her nipples and pubic area, but most of them crawled to her armpits, near her buttocks, behind her knees, between her toes, and other places that could hardly be called sexual areas.

Alp tried to crush each one with her hand, but there were so many of them, and more importantly, "they wouldn't die from that".

Slime, a mucus creature.

Separated from the main body, they were short-lived, but they have enough vitality to survive the night.

How long had it been―― a short time that felt like an eternity to the cowering Alp, but was actually less than ten minutes―― Alp's mind was being worn down.

(Don't come... those footsteps...)

Cutlet, cutlet*.

The sound of boots hitting the stone floor echoed in the darkness.

It was a small sound.

The intruder might not want Kara and the other researchers in the research tower to know about their existence, but Alp didn't think about it.

Just desperately repeating in her mind, "Don't come" and "Don't notice", she curled her body up and endured the stimulation from the slime crawling under her innerwear.

"......, ......, ...!?"

Twitch*, her shoulders quivered.

The slime encircling her nipples, covered by her underwear and innerwear, was slowly biting, rolling, and playing with her erect nipples, rubbing them against the lining of her underwear.

Alp bit her lip in response to her shallow reaction, even though her head was filled with fear.

It was a new stimulus, not just the rubbing. It wasn't just the caress from the slimy liquid, but the stimulation from the sensitive bulge rubbing against the fabric.

The sensation startled her body into reacting.

Her left nipple was tugged and pushed into the overly rich flesh of her breast, and her entire areola was fumbled.

Beneath her bra, her breasts, softer and richer than the liquid slime, changed shape, fluttering back and forth like a child was playing with it, then fluttering again.

Her nipples became even harder, and even her areola began to swell.

The mucus from the slime enveloped not just the slightest irregularity of her nipple, but every pore from her areola, licking away the grime that had accumulated there.

It was an unbelievable stimulation.

It was a caress that she could never perform with her own fingers.

No, it was a pleasure that was impossible for a human being to do.

In addition to the uneven stimulation, her legs that were bent as she hugged it, twitched and reacted, and Alp unconsciously rubbed her thighs together.

(Only just my breasts, though...)

As a priestess, Alp felt like crying due to the shallow reaction of her body.

One of the slimes had already invaded the base of the underwear, and when it slipped inside it, it stimulated her clitoris, which was hidden by the foreskin.

"~ ~ ~ ~"

It was a miracle that she didn't make a sound.

The sound of walking behind Alp became louder.

As the owner of the sound came to the third floor.

"――?"

Cutlet, cutlet*.

Peta, peta*.

(......, ......?)

While she was repeatedly having small spasms from the stimulation provided by the slime under her underwear, Alp didn't miss the sound.

It was not the same as the tiny slime that crawled around her body, but it was a sticky sound.

It was the sound of people walking, but it was definitely coming from a distance.

(……Another person?)

Alp bit her lip to keep her charming voice from escaping, and gently peeked out from behind the desk.

She couldn't see the other person's face.

But she could see that her hair was long. And she was wearing a large triangular hat, like the ones in fairy tales.

The weak moonlight streaming in through the window reflected the outline of the hat in the darkness.

(A human...... woman……?)

She was tall but had a feminine, sexy body.

Her breasts were large, though not as large as Alp's, and her waist was thin.

From the staff in her hand, Alp guessed that the female intruder was a mage.

And then there was the other one.

This one was taller than the mage, even with the triangular hat she wore.

It had arms and legs and stood on two feet. It also had a head―― a human being.

But

(N-naked――!?)

Yes. Even in the darkness, the figure seemed to be unclothed.

Sleek shoulders, arms, upper body. The lower half of its body. She couldn't see a shade of cloth that could be considered clothing.

"Are you there?"

The voice sounded questioning, but the woman said it with conviction.

A high-pitched voice, beautiful and clear to the ear.

The next moment, without hesitation, she pointed the tip of her staff towards the desk where Alp was hiding.

(Why――!?)

Without knowing why she was noticed, Alp moved from the desk where she was hiding to another desk.

Immediately afterward.

"Wind, blow it away."

With a shortened chant, the magic was activated.

A gentle breeze blew in the darkness, followed immediately by a storm.

A wooden desk full of books and papers blew away and hit the wall, making a rumbling sound.

"Why so sudden!?"

"Oh, I've already killed about ten people."

Alp raised her voice, hiding behind another desk.

The woman's words brought to mind the faces of her colleagues downstairs.

"It's a girl, isn't it?"

The woman held out her other hand, which was not holding her staff, and seemed to put mana into it.

The magic that was invoked without any chanting was fire magic to light the area.

Three warm-colored flames, which would normally be calming, appeared and lit up the laboratory on the third floor of the research tower.

The room could be described as bleak.

Metal instruments, lab tables, and desks lined the room.

"Your relation with―― no matter."

The young Alp became agitated at the mere mention of the topic...... of her colleagues.

She guessed that was what they originally wanted.

The woman pointed her staff at Alp, who jumped out of the desk. But from there, the woman―― Frederica was not expecting it either.

There was enough distance.

For a mage, distance from an enemy was the lifeline.

The farther away one was, the better. The farther the distance, the more one could concentrate on their magic and the longer one could chant.

Magic chanting was a way to concentrate and refine its power. In fact, it was possible to "use magic" without it, but mages unaccustomed to combat were often nervous about the fight and fail to cast their spells.

It was a precautionary measure.

It was a way to concentrate on the battle by chanting and activating the spell correctly even if something unexpected happened.

Armed with that knowledge, Alp regretted it only after she had jumped out in rage at the distance between her and the enemy mage.

(Too far.)

There was a distance of three desks between Alp and Frederica. The space between the desks was wide, so the distance was actually much greater.

It was the result of hiding by the stairs and crawling on the opposite wall.

However.

"Wind――"

The attack was adjusted, so as not to kill.

Frederica was about to fire a shock to blow it up instead of slashing it, but she interrupted her short chant and jumped back to the side.

――A wooden desk full of contents flew at her.

"Wha!?"

In the darkness, an object of unbelievable mass flew by.

In terms of weight, it probably weighs more than an obese man.

Alp hit it with her mace, "holding back" so as not to shatter it.

In the face of the wooden desk that was coming at her, scattering, Frederica instinctively jumped to the side rather than intercept it with magic.

The chanting was cut off.

"You!"

One more time.

She pushed the desk away in the direction Frederica had fled.

"Nhyaa!?"

However, this time, she was way off the mark.

The minuscule slime that had burrowed into the valley of her buttocks just before she hit it, sucked hard on her anus.

She was startled by the creeping sensation as though a foreign object had been thrust into her asshole, and her body, against her will, forced her buttocks to tense on its own.

Her wet black innerwear bit into her buttocks and her toned flesh showed by straining her back, turning Alp's body at her back into an obscene sight.

After exerting herself, she curled her body and covered her breasts with her left hand that was not holding the mace.

Her breasts were still being caressed, though she forgot about it for a moment in her anger.

Her breasts, which were even bigger than Frederica's, were obscenely shaped by the arms holding them down, and her innerwear creased and dug into her fleshy breasts.

Her legs were showing and her knees bent freely.

Shudder*.

The stimulation on her neck. She was in the middle of a battle, but it didn't care, as the slime under her innerwear crawled out of her neck.

"This..."

Alp pushed the desk with the mace in her right hand to check Frederica, then grabbed the slime with her left hand as it tried to move from her neck to behind her ear, and threw it to the floor.

A mace destroyed half of the desk, and the desk that had been snapped in half was unluckily headed for Frederica.

――But the desk was destroyed midair.

It was not due to magic.

The humanoid that was with Frederica stretched out its arms like a whip and struck the approaching desk.

Alp was about to lose her mind when Frederica spoke, but she instantly calmed down.

Beyond the bright flames.

The humanoid, still in the shadows, was invisible.

However, the flames and the weak moonlight coming through the window made its outline appear in the darkness.

The eerie appearance of the figure gave Alp a feeling of dread, as though ice had been thrown down her spine.

"Eh!?"

It was Alp's turn to be surprised.

As though to mimic the previous attack, the humanoid stretched out its arms, lifted the desk, and threw it at Alp.

Alp couldn't stop its force and avoided the desk.

It was quite a force to be reckoned with. Even if she knocked it off with her mace, she judged that there was a high possibility that she would be injured by the debris.

"It's amazing."

The intruder―― Frederica was honestly impressed.

It was like a storm. A monstrous force that could turn anything in its path into a weapon.―― it was a threat to a genuine "mage" like Frederica.

With that kind of power, even a pebble on the ground could be deadly.

"I'm glad I'm not alone..."

But even though Frederica was surprised, she did not feel threatened.

At first, she was so startled that her body reacted on its own, but now the existence of an inhuman, reflex-driven being prevented all of that.

The Black Ooze, which had taken in countless humans, elves, and beastmen, had increased its will, and all of them were on guard around the "humanoid" form, which could be called a body.

All directions.

Up, down, left, right, everything.

It was a relief to know that it was impossible for a human being to break through that security net.

In addition.

"Haah, haah..."

One could see that Alp's breathing was uneven, echoing in the dark room.

It was such monstrous power. She expected her to have more physical strength than most people, but even so, "fighting while being caressed all over her body" would drain her physical and mental strength.

It was something that Frederica knew well, having fought the slime before.

"Now."

She knew from the start that one of them was heading to the top floor.

It was the tiny slime that was underneath Alp's clothes.

For the "humanoid"―― or rather, the Black Oozes―― that Frederica was with, being able to sense their own kind was not an ability that they acquired during the course of their evolution, but something that was there from the start.

It just lacked the ability to recognize and communicate it.

The Black Ooze was just a slime. They were monsters.

Without the existence of the being called the demon king, monsters would only congregate in groups of their own kind, which was why they do not need to perceive anyone other than themselves.

Monsters were so belligerent that there were even races that consider everyone other than themselves and their own kind as enemies.

However, this Black Ooze was different.

These were the same beings that multiply by using a woman's womb. In a way, they could be called a family or brothers.

That was probably why.

If the Black Oozes were not too far away, they could sense where each other were.

And now that it's taken in the blood of the hero and gained a kind of intelligence, it's "telling it to Frederica".

That was how she had been able to locate Alp even in the darkness.

"You can do whatever you want."

With that, Fredrica left Alp to the "humanoid slime".

It was not completely human, though.

It had hands, feet, and head.

But it had no fingers on its hands and feet, and no face.

It was a "shape that mimics a human". That was the identity of the other intruder that Alp had saw in the darkness.

"Kuh."

Alp's breathing became more erratic.

In order to avoid the counterattack earlier, the tiny slimes underneath her innerwear, which had been activated by the will of the "humanoid", now began to torment the sex zones of the priestess with a clear intention.

Nipples, pubic area, cleavage of her breasts and buttocks.

The slime rushed to her armpits and neck, which had responded so well during the movement.

It was as though her entire body was being licked and sucked under countless layers of stimulation, and her nipples and clitoris, her distinct sexual zones, were being rolled around.

Even though it was covered by her underwear and innerwear, her nipples were slightly raised, and her crotch area made a wet sound as her underwear sucked in her love juices.

Sweat steamed under her innerwear, which turned into heat, causing her to sweat even more.

While easily imagining Alp's condition, Frederica quickly found what she was looking for.

It was a metal box.

"Welcome back."

Without hesitation, Frederica opened the metal box and picked up the slime's nucleus that looked like a thumb-sized stone stored inside.

She placed it on her right palm and stroked it lovingly with her left hand.

There was even a smile on her face.

Ignoring the commotion behind her, she stroked it for a while and then looked around.

"Well now, let's continue."

What she saw was a shelf with many bottles of liquid chemicals.

Frederica pointed her staff at the shelf and activated her magic without even chanting.

The shockwave that was released destroyed the shelf and shattered the bottles that were lined up there. As the spilled chemicals spread out on the floor, she placed the nucleus of the slime on it.

The change was sudden.

The slime's nucleus absorbed the chemicals, increased its mass, and expanded.

"Haah, haah―― what, are you. What are you doing!?"

Alp, who turned her gaze to the sound of bottles shattering, asked.

She was out of breath.

Her movements were sluggish, and the hand holding the mace was shaking with fatigue.

"Mon, ster―― that's a monster, you know!?"

"I know what it is."

What's the big deal? Frederica responded to Alp with an expression and tone of voice that said she rather didn't understand why she was asking her such a thing.

In the meantime, the slime's nucleus continued to increase in mass and extended its tentacles to the surrounding desks.

It was a rapid acceleration that the slime had never performed before.

The wood it had taken in melted in the liquid as fast as it could be seen, and the slime gained mass as it melted.

It tried to reach out its tentacles to Frederica, who was right beside it, but its tentacles were blocked by the "humanoid".

Then the expanding slime retracted its tentacles.

(―― The slimes have hierarchical relationships, too......?)

Clearly, the expanding slime was afraid of the humanoid slime.

And the fact that Frederica, a human, was not afraid of the monster slime...... but on the contrary, was cooperating with it, which raises some questions.

"Why are you helping the slime――"

"You'll see."

The slime, which had realized that Frederica was no good, now pointed its tentacles at Alp.

It was so sudden.

"Kuh."

She tried to avoid the tentacle, but her legs got out of balance.

In addition to being dulled by fatigue and pleasure, the remnants of the desk that was destroyed earlier got in the way, causing her legs to twist.

She almost fell over, but not before the slime tentacle caught Alp's left wrist.

"Hii."

She remembered the memory of the time when she was attacked in the forest the other day.

She was saved by the tools from her companion, but now she was alone.

"No――"

She tried to scream, but a tentacle blocked her mouth.

She dropped her mace when the tentacle caught her right wrist and twisted it, then her legs, elbows, knees, neck, and waist.

Her entire body was bound by the tentacles, and she was lifted into the air.

It was a moment. It was easy for the slime to capture a human if it didn't care about its shape like the humanoid.

There was no need for traps or tactics, just pure physical difference.

It was not a person with two hands and two legs.

An infinite number of tentacles rushed to Alp's overly rich body. As the tentacles crawled over not only her arms and legs, but also her waist, breasts, and groin, she screamed, not caring that her mouth was sealed.

"Nghhh!? Nnhh~~~~!!"

Alp flailed her entire body and resisted.

Her breasts, which seemed to be spilling out even when held by a man's hands, trembled as though they were about to make a sound, and her hips rose and fell.

Even so, with her wrists, elbows, ankles, and knees bound, it was impossible for her to put up any kind of resistance. The result was that she became even more breathless, and Alp's resistance came to an end easily.

The only thing left was a woman with ample limbs, breathing weakly.

Even so, the tentacles' restraints did not loosen in the slightest, and they abruptly lowered Alp onto the desk.

She felt the hard surface of the desk against her underwear-covered buttocks.

She was lifted up on the desk with her hands above her head, exposing her armpits, and her legs were spread wide open to show off her crotch.

"Fuu, fuu..."

(What―― this smell...)

As she blushed with shame and take a deep breath to regulate her erratic breathing, she couldn't help but smell the odor rising from the tentacles covering her mouth.

It was a smell she had never smelled before.

If she had to use an analogy, she would say it reminded her of some kind of medicine―― a bitter medicine prescribed by a doctor. The smell reminded her of that.

However, after smelling it many times, it did not bother her, in fact, it made her want to smell it even more......

"See you later."

At the sound of her voice, Alp, whose thoughts were almost caught up in the smell of the tentacles, raised her head.

She turned her gaze to the direction of the voice, to the woman, Frederica.

"Don't give me that look, okay?"

Alp unconsciously looked at Frederica, the only one who could speak in the situation, as though asking for help.

Naturally.

After all, her entire body was now completely restrained.

She was in a state where it was impossible for her to resist, let alone escape, so it was only natural that she would seek help from her enemy.

But

"Earlier, you asked me something like, "Why are you helping the slime?" You asked me something like that earlier, didn't you?"

Alp had no idea what Frederica was talking about.

She just wanted her to help her.

She appealed to Frederica with eyes that trembled with fear.

Tears welled up in the corners of her eyes and spilled out.

"It's fine, because tomorrow morning you should know why."

"Ngh!? Nghhh~~!!"

While listening to Alp's tragic moan, however, Frederica and the humanoid slime went down the stairs as though they had lost further interest.

Only the light of the fire she left behind illuminated the room on the third floor of the research tower.

In the warm glow of the light, a dirty slime's soft body was stirring. It absorbed everything it could, expanded itself, and moved its body downstairs and upstairs.

It didn't care if it was a new tool, a thing, or a person.

And for the captured Alp...

(No, nooo!!)

"Nghhhh!!"

It rubbed her breasts over her ultra-thin underwear, kneaded her buttocks, thrust up the stricture at the back of her cleavage, and rubbed up against her nipples, which were so erect that they were visible even through her underwear and innerwear.

Goosebumps broke out all over her body.

(That's disgusting―― that's disgusting......)

The slime's soft body was warm to the touch.

It was not as warm as human skin, but it was not as cold as it felt.

That was why she felt the presence so strongly, and with tears streaming down her face, Alp shook her head, which she could move slightly, and pleaded with it in her heart to stop.

Of course, such feelings were not conveyed, and the tentacles began to play with Alp's body in earnest.

The tentacle that changed its shape to look like a sucker caught her left nipple and pulled her nipple to lift her left breast.

Four thin tentacles entwined around her right nipple, each with a completely different technique to play with the erect nipple, as well as the tiny dimple in the mammary gland.

"Fuu... nghhh!?"

(No, w-what... what is this!?)

It was an inhuman technique that could never be performed with human fingers or tongues.

The nipples were stimulated and penetrated her entire body like an electric shock.

With just the stimulation, Alp struggled to move her restrained hips, her body flailing to escape the stimulation.

She squeezed her fingers that she could move and tried to endure the pain that clawed at her palm.

It was pointless.

Rather, the fact that she was straining her entire body made her feel the intensity of the stimulation even more.

"Nghh, fuu, fuu!?"

(Coming out―― something. Something's coming out!?)

Something would erupt from her chest. That was what she thought.

In fact, there was no way that Alp, who was still a virgin, would be able to produce breast milk, let alone get pregnant, but for sure, at that moment, Alp felt something overflowing from the tip of her nipple, which was erect to an extent that she did not even know was there.

It was mana, something that every person had, no matter how big or small it was.

And it was what the slime desired most.

Alp's climax caused her to release her mana along with her sweat, and her eyes rolled back at the unbelievable feeling of release.

"Haah, haah, haah."

While repeating short breaths like a dog, Alp looked at her chest.

Of course, nothing was gushing out.

It was wet with slime mucus, but there was no such thing as breast milk that was making it wet―― and yet.

(What... what, just now...)

Her teeth were rattling in her mouth, which was blocked by the slime.

(It's so scary...)

She felt "something" gushing out of her body.

The feeling of "something" being pulled out of her chest.

If she were to compare it to "the feeling of release after removing impurities that were clogging up her body"―― the difference was whether it was an object or herself.

The ultimate feeling of release and liberation was simply terrifying for Alp.

"Haah, haah..."

(No, no, no...)

Her eyes opened wide and she stared at her chest.

The tentacles that had just drained the mana from both of Alp's breasts were swaying in front of her gaze, catching her nipples.

Even if she didn't want to, she couldn't help but stare at its movements.

She was going to be given that pleasure again―― Alp struggled to keep her teeth from trembling in fear, trying to endure it.

She bit it down.

However, her teeth that were clenched easily lost their strength.

"Fuu!?"

Alp's sealed mouth screamed in delight from her throat as her nipples that were being sucked by tentacles changed their shape and formed a mouth with hundreds or thousands of tiny tentacles inside.

The intense sensation from her erect nipples rubbing up through her innerwear made Alp easily roll her eyes back.

Alp's nipples were larger than most women's in comparison to her huge breasts.

Her nipples, erected to the size of the tip of a pinky finger, were an easy target for the tentacles, so much so that the size of the nipples would lift her innerwear if the slime under her underwear released it.

The mouth tentacle, with its countless tentacles, added such a large, easy-to-target weakness, and rubbed up against her nipples from all directions with the tentacles in its mouth.

"Fuu!? Fuu!? ...!? Nghh!?"

(Nipples―― nipples, my nipples!?)

Too much stimulation was like pain.

But it was not painful at all.

The pleasure was so strong that her brain could not comprehend it, and Alp easily let go of her consciousness, sniffling and eyes rolled back.

The lower half of her body twitched like a broken toy, and the spurting liquid further soaked in her innerwear, making a wet sound.

"Fuu, haa―― nfuuu!?"

It was only for a moment that she had fainted.

When she regained consciousness, the stimulation from her chest made her scream again.

Then, after screaming longer than before, she lost consciousness again.

Her brain couldn't take the pleasure from the tentacles, so she was forced to pass out to protect her mind.

However, her body was stimulated by the pleasant sensation, which awakened Alp's consciousness.

It was a vicious cycle.

Alp fainted and woke up again and again, and when her face became soggy with sweat, tears, and snot, she was finally released.

"――, ――――, ……"

Even though her breasts were released, her body was still experiencing pleasure, and her hips were twitching on their own.

Her hands, which had been clenched painfully, became stiff and immobile, and her legs, which had been propped up repeatedly, hung down without any strength.

Her peach-colored hair, which had been tied up in a ponytail, absorbed the sweat and became disheveled, sticking to her cheeks and forehead, adding to the sense of humiliation.

......There was not the slightest bit of drive on those eyes.

However, there was fear.

She was terrified.

She was scared.

"――――Unhh."

(――――Nooo.)

Alp shed new tears.

The tentacle changed the shape of its tip―― a sharp blade like a knife.

It scratched it into the chest part of her innerwear.

It was obvious what it was trying to do.

The blade pulled at her innerwear, lifted it, and after a slight resistance, tore it apart.

Underneath her black innerwear, her pure white, untanned skin was revealed. Her breasts, tightly squeezed by the thin fabric, trembled heavily with a generous amount of volume.

Her rich breasts, wrapped in peach-colored underwear that resembled her hair, swayed repeatedly, almost making a thumping sound, as though rejoicing in their release, and it took a little while for them to calm down.

Her skin was so white that one could almost see through the veins.

Her underwear may not be the right size, but her overly rich breasts were literally "squeezed in" to create a deep cleavage.

There were countless dirty black tentacles crawling all over her.

The tentacles burrowed under her underwear and pulled the hooks at the front to easily undo her underwear.

The overwhelming mass of her breasts swayed with its weight and fell out.

The overly large breasts sagged slightly as gravity pulled them down, but they were rather fleshy.

Her nipples, illuminated by the magic light, looked larger than she had felt through her innerwear. They were about the size of the tip of her pinky finger and could easily be pinched by human fingers.

Likewise, its areola was also large.

Both of them were bloodshot and lumpy due to the pleasure.

Her nipples were swollen and erect to a degree that even Alp herself did not know.

At the tip of her nipple, one could see the dimple of its mammary gland, which was still twitching on its own in search of pleasure.

"Uu, uuu."

Alp cried out again as her nipples became painfully erect.

When she shook her body, her mucus-soaked breasts swayed heavily from side to side.

That was all.

All Alp could do now was shake her breasts.

And just by doing that, she felt a tingle in the back of her chest.

Every time the bulge swayed, pleasure built up in the depths of her breasts, and she felt as though her sensitivity would increase without limit, which terrified her.

(No. I don't want to feel any better than this.)

She couldn't even deny it anymore.

Her breasts were being played with.

Her mana was taken away.

Not only could she not endure the unknown pleasure, but she also couldn't even endure her shallow body that was just horrible.

Alp looked at the tentacle with eyes that trembled with fear.

"Nghhh..."

(No more...)

The tentacle lifted its sickle-like tip, dripping with a transparent liquid.

The tip was shaped like a small blunt tool with countless tentacles growing out of it.

The sticky mucus dripped down onto Alp's huge breasts.

"Nhh."

When the mucus dripped onto her hard erect nipples as though it was aimed at them, a voice escaped from her throat.

(What... what kind of liquid is this...)

There was no immediate change.

But the clear liquid stained her breasts around her nipples. Illuminated by the magic light, Alp could only see the scene.

At the same time, the tentacles were unable to provide any further stimulation.

The violent pleasure of intermittent loss of her consciousness that she had just experienced―― there was no.......

(No, wrong... that's wrong.)

If It was going to do it, It would have done it more violently―― she hastily denied herself that she had almost thought that for a moment.

When she shook her head, her breasts shook heavily.......

"...Nhh, ......, ......"

Shock*.

Her two legs that were thrown out from the desk where she was sitting trembled.

Without her being aware of it, her feet curled her toes in her boots on their own. Her grip on her hand tightened, and finally, Alp realized that her body had changed.

"Fuu, fuu?"

(Eh… eh...…?)

Her nipples became erect on their own.

Her nipples, which she had thought were at their limit, hardened a little more on their own, right in front of Alp's eyes.

Her nipples were changing in front of her eyes―― Alp, who could only watch, was baffled.

(Why? Why?)

Even though she didn't feel anything―― she thought so.

In fact, her brain was rejecting the sensation.

Because it was too strong.

"――Nhhhhhhh!?"

"It" was sudden.

(Itch, itchy――― so itchyyy!?)

Alp flailed her restrained body and lifted her body as hard as she could.

Tears well up from her upturned face as she thrust her breasts into the tentacles.

(My breasts, my breasts are itchy!? My breasts are itchyyy!?)

"Nghhh!? Nghhhhh!!"

(Breasts, My breeeaaaaasts!!)

Alp didn't understand what had happened.

She just felt an itch in her chest.

An unusual, unnerving itching sensation.

Her nipples and breasts swelled up as though they were begging to be touched and scratched, and her body thrust her breasts towards the tentacles on its own.

"Nfuu!! Nfuuu!!"

(Itchy!! Itchyyy!!)

Her feet were stretched down to the tips of her toes, and her ankles were straining to show off their inner muscles.

Her hips were flailing on the desk, making a splashing sound that made it easy to imagine how disastrous it would be underneath her innerwear.

The sound of the water seemed to be getting louder with each time Alp flailed about.

Was it sweat, love juice, or some other liquid?

Alp desperately thrusts her chest out, spilling all kinds of bodily fluids all over her body.

"Nhhh!!"

(Touch it! Touch it!! Touch iiit!!)

The thought of resisting or holding back didn't come to her mind for a moment.

Her chest itched.

That was the only thought that occupied her mind.

Alp looked at the tentacles with wide and a desperate look in her eyes―― she was horrified.

"Nfuu!?"

(No, noooo!?)

As expected, the tentacle was pointing its blade at the lower part of her body―― the innerwear that hid her pubic area.

Behind it was a tentacle that spilled the clear liquid that was just dripped on her chest.

(Stop, that, stop iiit!!)

"Fuu! Nfuuu!?"

The slime didn't stop moving, even though she desperately shook her head and complained that she couldn't hold back any longer. The knife-sharp tentacle hooked its tip into the innerwear of her crotch―― tearing it apart just as easily as earlier.

Her pretty peach-colored panties, decorated with white lace, were mostly wet with her own sweat, love juices, and the mucus of the slime that had burrowed in.

The liquid, a mixture of various bodily fluids that had accumulated inside her underwear, spilled out and dripped down the desk in strings.

The slime moved its tentacles to absorb every drop of it, and Alp was able to see that.

"Uu, uuu..."

But Alp had no time to feel such things.

Her heart was racing unbelievably fast, and her eyes were glued to the tentacle between her legs that was dripping a clear liquid that was slowly coming closer and closer.

(It's so hard with just my breasts, but now I'm going to have to go to...... in my vagina.)

She felt as though her heart was pounding in her ears.

She was so nervous and scared that her entire body tensed up and she tried to squeeze her legs together to hold on.

He knew that it was impossible and pointless, but it was the desperate action that her body chose to take in order to protect Alp.

She tried to block the tentacles with much force that her abdominal muscles were rising.

"Uu, uuu..."

The tentacle was gradually approaching.

It only made her chest itch earlier, and just the thought of that stimulation on her weaker parts made Alp's nether regions leak new love juices.

Her labia twitched obscenely as she strained, and her slime-covered clitoris was out of its foreskin in the translucent liquid, exposing its beautiful scarlet flesh pearl.

Her clitoris twitched a little in the slime liquid, as though imagining the stimulation to come.

(It's... it's coming.)

She knew what would happen, and she could see the moment it would come.

The tentacle that spilled the clear liquid touched her pubic area over her peach-colored underwear, smearing the lewd liquid back and forth between her legs over and over again in an attempt to soak it into her skin.

Each time, Alp felt a faint stimulation that caused her shoulders to shake slightly.

(It's only this much stimulation, but......)

It was only a slight stimulation that she felt through the thin fabric of her underwear, but her pubic area opened up in search of pleasure, and the sensitive mucous membranes rubbed against the fabric, tingling and stimulating the back of her waist like static electricity.

It was enough to make Alp almost let out a sweet cry from her throat.

She almost lost the strength from her clenched teeth and hurriedly pulled herself together.

"Fuu... nhh."

Alp clenched her teeth.

At first, nothing happened.

She knew. She should know――.

"Uu, uuu~~~~~~ !?"

(It's here―― It's here, here, here, here...!!)

"Fuuuu!?"

Itchy. Itchy, itchy, itchy, itchy, itchy, itchy, itchy.

Itchy!!

"Fuu!? Fuuu!!"

Alp's body flailed frantically in spite of the restraints.

She thrust her hips and shook her breasts, desperately trying to receive the stimulation.

(Itchy! Itchyyy!! My breasts and vagina too!!)

Her eyes widen, her overly large breasts flail up and down, left and right, and her body flailed as she lifted her hips off the desk.

Her nipples, erect to the point where she didn't even know they were there, dance around in the room lit by the magic from the fire like a conductor's rod.

(Touch it, touch it!! Someone touch iiit!!)

It was too itchy.

She was going crazy.

Completely out of her mind―― Alp thought.

It itched, but she couldn't scratch it.

Just the touch from the air stimulated her breasts and lower body, but it was not enough, and the frustration was building up.

"Fuaaahh!! Muoooo!!!"

(Touch iiit!! My breasts and vaginaaa!!)

Alp shook her breasts and hips as hard as she could, screaming wildly in a way that a virgin woman would not be able to―― or even a small-time prostitute.

She knew that the slime would violate a woman.

It was attempted before, but Alp was the woman who fell prey to it.

That was why,

(Touch it, touch meeee!)

With a desperate plea that not even a whore would make, Alp shook her breasts and bucked her hips against the slime.

The love juice that could not be held by her underwear spilled, and the slime retracted its tentacles as they sucked up the lewd liquid.

(Why, whyyy!? Why won't you touch it!?)

With tears and snot dripping down her face, Alp desperately shook her hips.

Then, there was a movement behind her―― the slime extended its tentacles from the back of her neck and began to cover Alp's face.

"Fuu!? Fuo, Muoo!?"

(Why, why!?)

Her vision was blocked.

Her ears were blocked.

She couldn't see anything, she couldn't hear anything, and her thoughts were dominated only by the itchiness in her chest and groin.

(Please, please. Please!! Touch it please, touch it pleaaase!!)

Alp's thoughts were no longer able to think of anything else.

The itchiness.

Many people might consider it a weak stimulus to be given to humans.

Certainly, an itch was not enough to kill someone.

It was a minor stimulus.

It was a weak sensation that only tickled.

However, humans can't stand that sensation―― it was a weak and insignificant stimulus, but they didn't have any way to tolerate it.

The body would just run away from the sensation.

Whether it was an armpit tickle or an insect bite.

Next time, one would try not to be tickled or bitten by insects.

If one felt an itch, they have to scratch it.

They didn't have to put up with it.

――If both hands were not restrained.

(Help, someone, touch my breasts and vaginaaa!!)

Alp continued to scream in the darkness.

While screaming inaudibly, hoping that anyone would help her.

It didn't matter if it was a stranger or a monster.

She really didn't care who it was, as long as they could save her from her itchy sensation.

"Fuu―― Fugiii!!!"

She bit at the tentacles blocking her mouth and frantically flailing her body.

She might feel pain, she might get killed.

But more than that, she didn't even care about a little pain as long as she could get out of the itchy feeling.

Just the feel of the wind caressing her skin made me squirt from the depths of her peach-colored underwear, and the liquid was absorbed by the slime in front of her.

Still, in her underwear, with only her chest and crotch exposed, Alp felt a brief moment of darkness that felt like an eternity to her.

"Kuh... Not for much longer."

"Help will be here tomorrow morning... right?"

"We're a long way from the temple, so I'd say we've got till noon or so to think about it."

"Even in such a case, I need to keep my cool."

"It's times like these that we need to be sure our information is accurate."

The fourth floor of the research tower.

Kara, who was holed up in her room, was giving the most accurate reply she could think of to her colleague, the male researcher.

There was no intention to make him hope for something.

However, it would be in her nature to tell him exactly what was going to happen.

The male researcher replied in dismay, but he did not blame Kara for that.

He wondered if he was the same way. That was what he was thinking.

Instead of being cornered into a state of panic, Kara's calm questions and answers allowed him to think things through calmly as well.

"My question is, did the slime use the stairs to get up there?"

"...What is that?"

"I know what the slime is capable of, and how powerful it is, even though it's only on paper. Now that it has gained mass, it should be able to destroy the research tower with ease."

However, the slime used the stairs to climb up.

Did that mean that it didn't intend to destroy the research tower?

As Kara came to that thought, a thought occurred to her.

"The reason why they want to occupy it without destroying it..."

"Is it because the research in this tower is of use to the slime as well?"

The male researcher said as he leaned his back against the wall on the opposite side of the door.

"Use, value?"

"To take in the research―― or because the rare tools are important to them."

“…………”

The word "value" was going around in Kara's head.

At the same time, there was a strong bang on the door.

It was only a matter of time before the slime breakthrough into the room.

But―― Kara felt...... it was trying to avoid destroying the research tower any more than necessary.

Far from being a wooden door, the wall shouldn't be an obstacle for the slime.

"Worth using, huh?"

"...Kara-sama?"

"I see. So the goal is to occupy the tower――"

Whether that was why it let itself caught, or whether someone had helped the slime...... Kara could only guess, but she was certain that someone―― or another slime was working in the dark.

"What's wrong, Kara-sama?"

"Even if I understood, there is nothing I can do now."

Carla laughed helplessly.

"Hii."

At the same time, the man screamed.

The furniture blocking the door collapsed by the impact from the slime that was trying to open the door.

The sound made him press his back hard against the wall, trying to get as much distance as possible from the door.

Kara put her hand on the sword at her waist, but as she calmly wondered what she could do with such a thing, she quickly realized how pointless her resistance was.

Even so, faced with a situation that she had only known about on paper, and had never imagined what she would become when she was defiled by the slime, Kara realized for the first time that her legs were shaking.

(Am I scared... me?)

When she became aware of that, her hands began to tremble.

Her left hand, which was holding the scabbard, trembled, and the scabbard made a rattling sound as it hit the metal clasp on her belt.

It was right after that.

A part of the door shattered, and a part of the slime peeked out from it.

Once the door was destroyed, it was instantaneous.

The tentacles that had entered through the gap roughly threw away the furniture that blocked the entrance and dexterously unlocked the door.

It was like the movement of a human hand.

(It knew how to open the door...)

I knew it.

Kara was convinced of her idea.

"Someone must have told it what to do―― or something it had taken in."

"Kara-sama?"

Before Kara could finish her monologue, the man was pinned to the wall.

The tentacles easily crushed the man, as though to say that he was in the way.

It was a thin tentacle.

It was as thin as an adult man's arm.

And yet, it caught him precisely in the throat and snapped his neck.

――Kara drew her sword firmly.

She should have drawn her sword and slashed the tentacle.

But...

(It would regenerate if I cut it――)

She bit her lip.

Kara understood that she could not resist with just a sword.

But she could not take any countermeasures. Even though she knew it, even though she knew it was pointless, she couldn't do anything about it without any tools.

That was the limit of human beings.

Her hand trembled as she gripped her sword.

And she was able to point the tip of the sword at the slime, but the tip shook up and down violently.

In the first place, how much meaning does this sword have――.

"... Haah... haah..."

She tried to get her breathing under control.

She tried to regain her broken heart.

However.

"――――"

When she saw the person who came into the room, Kara found herself going blank.

It was a woman.

A woman with ample breasts.

More than half of her face was covered in black mucus, but her peach-colored hair was familiar.

"Al, p――"

Kara called out her name, but Alp didn't respond.

She had her eyes, ears, and mouth covered, completely blocking out all information.

(She probably doesn't understand where she is now.)

She calmly thought.

Alp was in a terrible state.

The chest and crotch parts of her underwear were torn off, and her underwear was so wet and was sticking to her body.

Her exposed nipples were bigger, thicker, and harder than Kara could ever imagine.

She looked frail, but she felt like a neat and good-natured woman.

She had only spoken to her a handful of times―― but the miserable state of the people assigned to the research tower upset Kara.

What felt worse than anything else was, that Alp was frantically shaking her breasts and hips.

"Nfuu!! Nhhhhh!!"

She was screaming wildly, her breasts swaying sloppily, and her hips moving up and down obscenely.

The warrior priest's behavior was too pathetic for a servant of the Goddess, and Kara felt dizzy.

Seeing Kara like that...... the slime thought of something and removed the tentacle that was blocking Alp's mouth.

"Please, please!! Touch it please, please touch my chest and vagina. Please make a mess of it!! Please, please dooo!!"

"――――"

Tap*.

Her back touched something hard.

It was a wall.

The wall of the room.

Kara was unconsciously trying to get away from Alp, who was desperately begging the monster to rape her.

"... Wha, ah...?"

She desperately pointed her trembling sword at the slime.

As though to say, "I'm going to do this to you, too," the slime flooded Alp's overly large breasts with several tentacles and plunged a very thick tentacle into her vagina without hesitation.

"Hyaaahhh!?"

It was a scream.

It was a scream, a cry of joy.

Alp's entire body convulsed morbidly, squirting vigorously as she convulsed again and again and again.

She climaxed.

......Right in front of Kara.
