Inside the Cave of Obscenity Vol 03 Chp 01 Part 4


“Nn, ah…”

A bewitching, passionate moan escaped her lips.

Her lips were parted slightly as though begging for something. Her small tongue sometimes peeked its way through, licking her lips in an irresistibly obscene manner—like she was enticing a man, like she couldn’t hold the passion in her body back. An action that would be unthinkable from her usual self.

This woman—the silver knight, Fiana, who’d come to this abandoned mine together with Alfira, was spread out collapsed on a bed of mucus. Although her slight stirrs here and there appeared to indicate that she was asleep, with her limbs were all spread out and held in place at the elbows and knees, making it so that she wouldn’t have been able to move much even if she had been awake.

She did not have the sword she’d used to slay numerous monsters in her hand, nor was it in its scabbard at her waist. Her armor had been removed, so all she wore was her nun-like robe.

Her eyes were staring at the ceiling, but they saw nothing.

Her eyes held no light in them.

Her eyes open yet unseeing, Fiana’s body was forced into its stirring.


A certain sound echoed through the cave. Unlike the woman’s heated, sweet moans, it was a disgusting sound. Even hearing this sound, Fiana did nothing but stare blankly at the ceiling.


Her body quivered.

It wasn’t that she climaxed. However, it was that she’d felt a definite pleasure. Her mucus-soaked clothing sliding and sloshing, further disgusting sounds could be heard. Her waist, hidden by her robe’s nun-like apron, shook fruitlessly.

Her black garter belt peeked out through the slits in her robe. Fair white skin, silvery hair, and white clothes. She was brilliantly bright head to toe save for her listless red eyes and black garter belt.

As if to defile that brightness, black tentacles crawled across her well-structured body.

Shlick, shlick.

Unparalleled obscene sounds still echoing through the cave, it caressed her still-bra-protected breasts from beneath and from under her bra, causing them to bounce around and produce even more sound. It was a sound built up through two definite bundles of fat covered by mucus being sloshed around as they continually attempted to return their normal shape.

It could be said that the petite Fiana having such giant breasts was imbalanced. Almost like it were playing with them, the tentacles lifted them up two or three times and let them fall back down, each time letting out another obscene sound.

Impatiently shaking her hips each and every time, Fiana… that is, the veteran knight accepted its loving, her expression tinged with lust.

She felt great.

Wrapped in a soft warmth, her entire body was being caressed and massaged. Her shoulders, arms, palms, fingers, thighs, calves, everything.

Her whole body being caressed, she felt her entire body flush. Being massaged while her mind felt like it was submerged in comfortably warm water, she let out a comforted sigh.

Fiana was dreaming with her eyes wide open, seeing dreamlike things.

Someone was caressing her. She just couldn’t figure out who was doing it.

Perhaps it wasn’t a question of who, but a question of what? Perhaps it was an abominable monster?

Either way, Fiana couldn’t figure it out. Her was being caressed all over, and she accepted that comfort whole-heartedly, letting out sweet sighs. She came to the conclusion that this was a natural feeling, which meant that being caressed like this was natural too.

Not holding any doubts about it, she could feel herself growing warmer moment by moment, growing more passioned moment by moment. She could feel her body trembling.

This was natural.

“—Ha, ah—ah… aah…”

Sweet, warm. Warm, sweet. The passioned moan of a woman.

Each time Fiana moaned, the Black Ooze caressed her. She wasn’t quite as petite as Satia, but more so than Satia, she was about as well-fleshed as Frederica, rivaling her. It caressed her, molded her.

Saying that she’d been defeated would be incorrect. However, it is true that she’d been neutralized by the Black Ooze. Yet no matter how effective it was at neutralizing people, the Black Ooze wouldn’t forget. It would remember.

Therefore, similar to Frederica, similar to Satia, the best way for it to make use of this strong woman would be to use her as a nursery bed in this abandoned mine. For the Black Ooze, which had only eaten men, this was the sole means it had to deal with them.

It had their experience, their knowledge as men. Making women fall, impregnating them, having them give birth. It would use this experience to obtain Fiana.

To obtain the strong mother body known as Fiana. To birth strong children. Dulling her consciousness through magic so that she wouldn’t resist, it made her react through honest instincts, domesticating her through pleasure.

Slowly, oh so slowly.

The Black Ooze held no concept of time. Although it knew what morning and night were as it were also part of the knowledge it had gained, it didn’t care either way. No, rather it didn’t think about it at all.

It just did nothing but pleasure Fiana and the other female knight, Alfira. No matter how long, how many days, or how many weeks, it would continue until the women reached the point of being able to bear its children. It would then continue having them birth children. The Black Ooze would repeat this conduct unconcerned of anything else.

Her well-built body grew tender, forged by fiery licentiousness, melted by pleasure.


Fiana breathed out a sweet moan… it was by just a small amount, but she shook her waist.

She’d also arrived at a bit of a climax.

Passioned breaths tickled her nose. Her sighs growing rougher, shallower, quicker—that they were growing more wild, she knew. Bit by bit, Fiana’s body started to accept the Black Ooze.

The change was slow, but as time passed on, it grew more apparent. The interval between her waist trembling shortened little by little, her whole body eventually joining in. With her body still affixed outstretched to the mucus bed, she stirred with rough breathing.

And, again, her waist quivered.

This repeated.

For Fiana and her mature body, these caresses were equivalent to torture. Even Satia and her yet-mature body found them to be enough to bring her to tears.

Even though she wasn’t conscious, Fiana’s body moved of its own volition, as it to beg for more of those torture-like caresses.

“Ah—not… there…”

Unconscious, Fiana spoke.

It was her reaction in opposition to the tentacles playing with her breasts.

There were slight protrusions at the tips of her breasts, held below her soaked clothing and bra. Her nipples were erect enough to be seen from beneath her clothing.

The tentacles grazed those peaks, causing Fiana to give obvious reactions despite still being clad in those thick clothes. Her all-too-abundant chest appeared to be rather sensitive.

Noticing that Fiana’s peaks were visibly erect through her clothes, the Black Ooze pressed into them.


The tentacles’ tips pressed into her soft, large breasts. When it did so, Fiana’s body arced in a torrent of pleasure.

Her bra and genitals were hidden by her apron, but she seemed all the more licentious due to reacting so visibly despite still being clothed.

Her legs were open wide, her chest was thrust toward the ceiling, and her mouth was wide open, moaning.

Her eyes still didn’t have any light within them, but Fiana still managed to convey what she felt to the Black Ooze as she looked upward.

That she felt comfortable, felt pleasure, and that she wanted more.

Even with her honest reactions, though, the Black Ooze’s course of action had already been decided.

Not comprehending her words, the monster would follow its instincts and modify Fiana into a mother body.

“Aah—ah, aahuu…”

The trembling in her limbs grew more visible. Her chest, shoulders, armpits, even though those were all that were being massaged, she was about to climax.

Still in her dreamlike state, Fiana wasn’t attempting to conceal her pleasure in the least, despite being so near to a monster, something she should have detested. Her body showed the fact that she was nearing a climax.

The Black Ooze wasn’t about to stop caressing her softened body either, so she was at its mercy.

Her breathing grew more rough. She thrust her waist out and arced her back in accordance to the tentacle’s massaging movements. Her moaning, her breathing, her body, everything was a reaction to her instincts demanding to climax.

“… Har… der…”

Her voice weak, Fiana spoke.

Just then, there was a slight change in the Black Ooze. It massaged her chest, stimulating her nipples. However, although the Black Ooze would have only been caressing Fiana to cause her to become ever more tender up till now, this time, as it was requested by Fiana, it crumpled her breasts even more vigorously.

“Nnn, nnn—”

Her expression loosened from the ecstasy. Her mouth curving into a smile out of pure delight, she threw her chest out as far as she could so that the tentacles would have an even easier time with them. It was but a slight change, yet it had answered a woman’s request. The change had happened.

This change was something the Black Ooze gained from the new men—the men that had come together with Fiana and Alfira, it was a change in sentiment. When it had violated Alfira, it had a bit of this intention.

However, that was all. It rubbed her breasts more forcibly, that was all. It crammed her twin peaks into her twin hills, that was all. It didn’t give Fiana any further stimulation despite her begging for it, but it continued caressing her entire body. The intention had been born, but it wouldn’t so easily prevail over instinct.

Just like how it hadn’t changed what it did to Satia no matter how much she begged for more, it only went as far as caressing Fiana’s relatively petite body for her age.

It wasn’t enough.

For a mature adult like Fiana, this was a torturous tease that only brought her a shallow climax.

Her waist trembled, thrusting out to the sky as if to seek out a certain something.

And then—

“Kuh, ah… aau, ah—ah—”

The massage continued. Her chest was massaged, her arms were massaged, her armpits were massaged. Everything repeated. This hellish torture… repeated.

Tears spilt from her vacant eyes. They were not from happiness. They were from agonizing pain, they were tears of sadness.

Not because she was being violated by a monster, oh no… it was because her flesh wasn’t being satisfied that she shed these sorrowful tears.

It was obvious to anyone who took a look at her. Her expression had changed. Even though she’d climaxed, her expression was cloudy and her body, lacking sufficient satisfaction, immediately began to once again thrust its waist back into the air. Her limbs were still bound to the mucus bed, causing her to be unable to move much. This lack of freedom is exactly what caused her desperate expression as she thrust her hips into the sky.

Shlick, shlick.

The sticky, disgusting sound grew ever more loud. Even louder than when she’d climaxed earlier. Not caring about that, Fiana—the female knight who had once attempted to defeat the Black Ooze, was now unconsciously shaking her waist at it, pleading for pleasure.

How much time had passed since this all started?

It felt like an eternity. Alfira being f*cked until she fainted, then Fiana and her dreamlike mind shaking her hips at the Black Ooze, begging for more fleshy satisfaction.

Two new figures emerged in the chaos.

No, they weren’t new. They were those who’d already been here. Two people who had been caught by the Black Ooze even before Fiana and Alfira were.

Frederica Rene and Satia.
