Inside the Cave of Obscenity-Vol 4 Chapter 10: Vol4 Final - The One who Possessed the Demon King (Brood Parasite)

"Onee-sama!"

After the slime in the abandoned mine was cleansed by the light from the holy sword, Mariabelle ran to Meltia who was restrained by the slime.

The traveling clothes she was wearing were torn apart and scattered around her, and all she had on was a small amount of underwear.

Even that was mostly stripped off and of no use.

Her entire body was covered in mucus and mud, but Mariabelle didn't care if her clothes were dirty, she held Meltia up.

"Nhh, hii―― ma, ria..."

"Onee-sama! Onee-sama!"

Relieved that her sister had answered her call, Mariabelle called out again and again.

However, there was something wrong.

When Mariabelle shook Meltia, that was all it took for Meltia to twitch a little, and then her eyes didn't reflect Mariabelle.......

"Hero-sama...... let go of Meltia."

"Eh?"

"She was poisoned―― it's a nasty poison that made her feel good just by touching her."

For a moment, she didn't know what Fenelieka was talking about.

The red-haired succubus got up on her own and approached Mariabelle, dragging her body to her side.

"Who knows about poison... Who is it? A priest or the woman with glasses? Anyway, just call them fast."

"Eh, ah... y-yes."

When she was told that, Mariabelle wanted to run, but she was unsure if it would be safe to move while her sister was unconscious, so she sat halfway up.

"Haa, hyuu... nhhh..."

"I'll take care of Meltia, so go."

Rebuking Mariabelle even though it was obvious that she was also exhausted, Fenelieka received Meltia, who kept twitching.

"Heavy......"

She couldn't feel any strength in her body.

Nevertheless, she was relieved that both of them have survived.

――Looking into the distance, she saw a different room from the innermost part. She could see that it was connected to the room where many succubus and neighboring village girls had been violated, probably by destroying the wall to shorten the path.

There, the succubus who had been freed from the slime's restraints were already on the move, waiting to see what would happen next.

"Ariade!!"

"Eh? Oh, isn't it Fenelieka!? Why are you with humans!?"

"Come over here! Give me some life force!"

"Huh...?"

The blue-haired succubus known as Ariade did as she was told and approached Fenelieka.

Fenelieka had a beautiful appearance that was far from human beings, but the female succubus named Ariade was a terrifyingly beautiful succubus.

She had shoulder-length blue hair and black horns like that of a goat.

Her breasts were not as large as Fenelieka's, but they were well shaped and stood upright even without the support of her underwear.

Her hips were so thin that it was doubtful that they were filled with internal organs, but the flesh from her waist to her hips was magnificent.

She stood beside Fenelieka, almost completely naked―― no shame in wearing only a black garter belt and stockings.

"Hey, give me some life force. I've been giving it to this girl all night and I've reached my limit......"

"No, why are you with a human? What's going on here?"

"The short answer is that we're getting rid of the slimes together. You should help us."

"Why are we......"

"The slime will just capture you again and violate you until you die...... And that black-haired girl is the hero. If you disobey, we will all be wiped out here."

"That's what I'm going to talk about."

The voice came from right beside her.

Kara, who had lowered a rope from the ceiling and descended to the place, directed her words briefly to Fenerieka and Ariade.

"If you help us, we'll keep you safe. Fenelieka has kept her word. But I'm not going to force you to do anything. If you don't help, well, I won't kill you here. I'll at least let you go."

"Wow. I saved the princess's life, and you say that?"

"I won't cut you because I owe you one...... Well, we'll talk about that later. Meltia-sama?"

"Haa, haa……"

Kara clicked her tongue in response to a fever-like reaction.

"Hey, Fenelieka. How much of that aphrodisiac did it give her?"

"Aphrodisiac? I don't know anything about that."

"It's a purple liquid. The slime is gray, you didn't see a different colored liquid?"

"Even if you told me that, I was desperate..."

"Tch. You're useless."

"Gununu..."

It was not much to say, but it was true that she didn't remember, so she couldn't say anything more back.

And she could see that Kara was in such a hurry that she didn't have time to choose her words.

"Ahー...... something, there might have been a liquid of that color around my mouth. I licked it all off because it looked dangerous."

"...Are you okay?"

"Not at all. What is that, is that the aphrodisiac?"

"It's amazing―― I see, hmm."

Kara took out a black pill in a bottle from the bag she was carrying, convinced of something.

"In case you're wondering, that's the medicine I'm using...... I hope it works. Meltia-sama, can you take it?"

She took out not only the pills but also a bag of water and tried to make her drink it, but the unconscious Meltia could not swallow the pills, which were about the size of the tip of her index finger.

"Here, lend it to me."

Fenelieka, who was watching, roughly snatched the pills and water bag from the side and put them in her mouth.

Without hesitation, she kissed Meltia and gave her the pills by mouth.

She put her tongue inside Meltia's mouth and guided the pill to the back of her throat.

But the pill was still too big for her to swallow, so she had no choice but to crush them with her teeth.

"Not good!"

"That's because I haven't adjusted the taste yet. What, you crushed it and made her drink it?"

"It can't be helped!? It was too big for her to swallow!"

Fenelieka went on to drink all the water in the bag and rinsed out her mouth until she finally spat it out.

Then Mariabelle returned with a warrior priest.

"Kara-sama, you're here?"

"Yes. I've given Meltia-sama some medicine. She'll probably be fine, but will you use the power of the goddess to help her recover?"

"Of course... Go away succubus. You guys don't like this light, right?"

His words were prickly, but he probably felt he owed her for saving Meltia, as he didn't suddenly use the power of the goddess.

(Well, it's a little better...... I guess.)

For now, she'll be content with that.

In a way, Fenelieka, who understood her position very well, seemed to be handling the situation much more rationally, and Kara broke her usual blank expression and smiled slightly.

"Is onee-sama okay...?"

"Yes. I gave her the medicine that the lady with the glasses there uses, so I think she'll be fine, Hero-sama. By the way, what kind of medicine is that?"

"It's an aphrodisiac neutralizer. The slime took in the aphrodisiac I made and increased its power, so I have to take it every day to keep my mind functioning properly."

"Pfft―― it took the medicine you made and then used it on you?"

"Yeah. I feel like crap."

Self-consciousness, regret, and other emotions seeped into her words, and Kara held her forehead with her right hand, her shoulders slumped down.

"You're pathetic."

"That's, Fenel-san!"

"Ah, it's okay, Mariabelle-sama. It is more refreshing to be laughed at and ridiculed than to be comforted. It's the result of my own stupidity."

"I didn't laugh to please you, but...... you're in heat all the time, aren't you?"

"If I take the medicine, I will feel calm."

It was rare.

She had only just met her, but she couldn't believe that this expressionless, glasses woman would talk about her weaknesses so easily.

When she wondered about that, Kara's shoulders slumped down.

"Think of it as a sign of trust."

"It's crap.... Well, I don't feel bad. That's just human approach."

"Thank you for protecting Meltia-sama all night, Fenelieka."

"Well, I don't know what it is, but I hope you get along, you two."

"Ah, of course."

"Yeah. So, Ariade, what are you going to do? I'm going to be working with this hero for a while longer."

When Fenelieka asked, the blue-haired succubus turned her head and looked at her friends behind the collapsed wall.

"Let me ask you something. Why are you working with the humans? If you're just going to lend them your power, from what I've heard, you've already done that, haven't you?"

"I've been asked to lend my strength to defeat the slimes. You see the succubus, Fenelieka, can fly......"

"Besides, apparently the succubus are resistant to sexual attacks and aphrodisiacs. It's a powerful poison that you can't get rid of for a long time after just one night of being dosed in it, but Fenelieka is already feeling better.

That ability is quite fascinating."

"As a decoy?"

"Yeah."

The woman who answered immediately was Kara.

Mariabelle was troubled by it, but――.

"I like honest people. It's much more trustworthy than pretending to be something you're not."

"But it's true that being violated by the slime is just unpleasant."

Fenelieka and Ariade didn't care much attention to Kara's words.

As long as they didn't get cut down right here and now for being a monster, it didn't matter. Mariabelle thought that the way they act may be the difference in values ​​between humans and monsters.

While talking, Meltia's breathing calmed down a little.

"Good, the medicine seems to have worked."

"……Onee-sama."

She was so overcome with emotion that Mariabelle had tears in her eyes, but Kara stopped her from picking her up.

"Let's get the horses and carry them to the village at the foot of the mountain. We should rest there and then return to Grabalt."

"Yes. We're on our own with the Valhari flowers――."

"No, that's no problem. I already found the flowers."

"Eh?"

Kara told them that if they went outside through the gap from the ceiling, above the abandoned mine, they would find Valhari flowers blooming all over the place.

When some of the beastmen went out, it was true that the national flower of Fonteau, the pure white flower, the Valhari were in bloom.

"... Isn't it too convenient?"

"Yeah, so I have my doubts."

"Maybe they didn't know that it was right under their noses?"

"No. The slime must have known that the flower is poisonous to them―― if, as I think, it shares the memories and experience of the person it has taken in."

"It's true that its sword technique and body language were very human-like."

"Then why are they leaving the Valhari flower? Now that they haven't been processed, those flowers shouldn't have any effect on them."

While the others were protecting the succubus and the village girls, Kara came up with a theory.

"Maybe that flower was originally a trap to lure us in."

"Us? Why?"

"In order to neutralize the hero Mariabelle-sama. It's also possible that they had some other idea in mind...... Well, there's not enough information to answer that question."

Kara got to that point and scratched her head messily.

"So there you have it. Did you notice anything strange while you were being attacked by the slime?"

"A lot of strange things. The slime, which is of a lower rank, doesn't listen to us, violated human women without killing them, and is terribly strong with magic...... right?"

Ariade said what she had been thinking and asked Fenelieka to agree with her.

The red-haired succubus had an idea when she heard those words.

"I was scared."

"Well, yeah. The thought of being violated for the rest of my life scares me......"

"No, I felt much, much scared of it than the Demon King."

"――――"

Ariade was at a loss for words there.

"More than the Demon King?"

"We monsters are created by the Demon King, and we are beings made to be absolutely obedient to him. We can't disobey his orders. Even if the enemy is the hero, even if we know we're going to die, we have to fight...... We can never disobey him. I felt that the slime was scarier than the Demon King."

It was a shock to the monster, as though its loyalty to its absolute master had been shaken.

At the same time, she confessed that the slime was "even more terrifying than the demon king". To the monsters, and Mariabelle, Kara, and most importantly, her kindred, Ariade understood the significance of that.

"So...... you think that slime is equal to the Demon King?"

"Now that the Demon King has been defeated by the heroes, we can no longer multiply. But the slime keeps on growing. It will change its form, and I'm sure it will split into more than one kind in the future...... Like the wolf that incapacitated us and took us away."

At those words, Kara lost her voice, and unconsciously, Mariabelle put all her strength into the hand that held the hilt of the holy sword.

When Mariabelle was fighting the humanoid, there was a shadow that ran out of the abandoned mine, replacing the humans who had entered.

It was a wolf.

No, it was a wolf-shaped slime with a strange wet glow all over its body.

It carried someone along with it.

“…………”

It was a woman.

She had beautiful blond hair and a large triangular hat. She was dressed roughly in a black undershirt and pants and wore a thick blue cloak over that.

Frederica Rene.

The female mage, who had been working with the humanoid slime, looked back at the abandoned mine one last time.

"It's a shame."

“…………”

The wolf didn't answer. Of course, even a normal animal couldn't speak, so there was no way that the beast-shaped wolf could speak.

Then Frederica stroked her stomach.

Lovingly. As though she were blessing her beloved child.

"Your father died, didn't he?"

There, a human-shaped―― a slime child was inhabiting it.

The child of the slime and Meltia. After the fertilized egg was transferred to Frederica's womb, Frederica and the wolf used the humanoid as a decoy to escape.

Or, to be more precise, a little different.

From the beginning, they had attacked Meltia for that very reason.

The "hero's blood" absorbed from Mariabelle was not enough.

It had planned to build a nest in a place where there were flowers that the humans were collecting to lure them in, but they came from the other side.

It was just that it happened to be the abandoned mithril mine where the Black Ooze was born.

That, too, must be fate, Frederica thought.

It would continue to grow and evolve without limit, no matter where it goes―― it was the same.

The dark-haired girl, and this slime.

In the back of the abandoned mine where Fenelieka was hiding, in the livestock room where Ariade and the others were being violated. That was where Frederica was, too.

There, while being violated together with them, Frederica placed Meltia's fertilized egg in her womb.

......Slime, but for the mutant Black Ooze to evolve further.

This time, instead of using the blood of the hero, it would use the egg of the hero's daughter.

"I know you'll win."

The wolf descended the mountain in a flash. As it was, Frederica crossed the border of Grabalt, passed through the forest, and headed for the ruins in Grabalt, where the holy sword of the hero was once placed.

Now that the holy sword was in their possession, the beastmen did not consider the ruins to be important.

That was why it was good enough to hide―― there was Satia, Frederica's only companion, who adored the Black Ooze as her master.

（I'll raise it there.)

While the heroes were busy fighting the slimes on the Royal Castle of Fonteau.

Nothing was out of schedule.

The human-shaped, the slimes, and the mutant Black Ooze―― just as they had planned.

"You're going to have to take care of me this time, right?"

Frederica gently stroked the wolf's neck, as though to take it to task for ignoring the succubus and village girls whose names she didn't know.

She wanted it to fuck her so hard that she would faint, that she would go even crazier than she already was, Frederica shamelessly wished.

To the slime.

To the enemy of mankind.
