Inside the Cave of Obscenity Vol 02 Chp 06 Part 4

Driven this far, it was likely impossible for her to endure the climax. As someone with little experience—no, as someone with no experience in being exposed to the pleasure a monster could bring, it was impossible for Alfira.

Even so, the reason she did her best at trying to endure it was because natural for her to do so as a human who had devoted their body and soul to living as a knight.

That pride, that dignity, is what tried to support Alfira and keep her going.

But such a trivial thing as that was of no concern to the slimes.

As far as the slimes were concerned, whatever feelings or disgust the female body’s owner held towards them were inconsequential.

That’s why however long Alfira tried enduring, persevering, and denying it all, what the Black Ooze would do wouldn’t change.


The tip of a tentacle that was massaging Alfira’s breasts became thinner right before her eyes.

This was also something that humans couldn’t do.

As for what the string-like, thinned tentacle aimed for, well, its target was the peak of one of her well-developed breasts—her nipple, ever-so-hidden within her modest areola.

“Kuh, stop it!”

Restrained by the tentacles, her upper body shook violently as she tried to escape from them. It was almost as though she’d just remembered she should do so.

However, the tentacles’ restraint was still strong. After climaxing over and over, her body wasn’t able to use even half of its normal power and she was unable to escape.

In the end, she stopped trying to the point that the only things still shaking were her long purple hair and her rich breasts.

At the very least, her current attempts at escaping that now caused her plentiful chest to sway could now only be seen as her attempting to entice a man.

“… O-ow—”

It was only advantageous to the side that was doing the restraining.

When the tentacle constricting her breasts did so more forcibly, she—who’d given up her struggles to that extent—looked pathetic.

The thinned tentacle held itself in front of the horizontal slit on her right breast—and aimed towards the nipple hidden within.


Unable to look away from the it, she bit her lip.

In her preparations to hold herself back from moaning, she had no room to mind her expression. Her eyes were open wide, her mind concentrated on her inverted nipples that she had a complex about.

If she couldn’t escape, she had no choice but to endure.

In her ears were voices from two other people.

The knight order had set out in order to investigate this mine, so there would definitely be a search party sent out if they didn’t return.

So until that time came, she just needed to endure.

As though she’d forgotten about her consecutive climaxes up till that point, her expression—while still displaying some dread—held a strong will.

At that moment, as if waiting for Alfira to properly prepare herself, the thin tentacle slithered into the thin hole on her areola, tickling her inverted nipple.


But just that was enough to cause her body to jolt upward. Alfira was unable to even control her own body’s reaction to something as simple as that.

That stimulation was a rather unknown shock to Alfira. Not having any friends with inverted nipples themselves, she wasn’t able to consult anyone about it, nor had she done something as extreme as touching them herself.

When the viscous tentacle infiltrated her hole by making use of its characteristics, a sharp pain bashed against Alfira’s mind.

She had been alive for twenty-seven years. During that time, she had never once touched her nipples and had never felt this sort of stimulation.

Her nipple, sensitive to the point of rivaling her clitoris, gave Alfira so much pleasure that it resembled pain.

“Stop, stop it! That’s—”

Conscious that her eyes had grown wet, she still tried to resist, her confidence still there.

However, the lips she’d been biting down on to suppress her voice parted. Instead of a moan, what came from her mouth was a demanding voice for the sake of preserving herself.

She desperately tried to drive the tentacles out of her inverted nipple by moving her body, but the stimulation she received merely intensified with each shake.

Even so, she couldn’t keep quiet. The stimulation to her nipple was simply too strong. She had comforted herself in the past through her vagina and clitoris, but never with her nipples.

The opposite might be true if she were an ordinary woman. However, as this was the first time Alfira’s nipples had ever been stimulated, she wasn’t able to come up with a way to endure the stimulation and simply continued to shake her body in a futile attempt to drive away the tentacles coiling themselves around her breasts.

This created a rather vicious cycle. A dull pleasure spread through her breasts with each and every shake as well as intensifying the stimulation to her nipple that was being licked and teased within her breast.

“Hu, uuun. H-hah—sto-stop it, please…”

This time, a second tentacle appeared, aiming towards her left breast. This one was also thinner than a human finger.

Alfira knew what this meant.

(Cut it out! Stop—)

It wasn’t the self-assured voice of a knight that. It was one of a woman.

It slipped in.

Together with that, a noise came from inside her wettened pants.


The slime inside her urethra resumed its activities.

Her attention focused on her breasts, it was practically a surprise attack. Unable to even have enough time to think about the matter, she tightened around the tentacle inside her urethra. As a result of her tightening, she felt the sensation of the tentacle moving inside her urethra all the stronger.

It was as though the slime knew the moment that Alfira’s mind had a gap in its armor.

Like the caresses up to this point was mere child’s play, the tentacle wrapping around her whole body came alive.


Her urethra violated from under her pants, her naked upper body’s breasts were tormented.

Her mind had even stopped working properly for a moment.

Her mouth stayed open as though she’d forgotten to close it. Drool dripped out of it, moving along her lips. Her breasts were covered with mucus as the tentacles continued massaging them.

Her vision grew moist. Not even Alfira knew if they were tears born from humility or joy, but her face was dyed in pleasure in every respect.

The once strong-willed eyes adorning her face now birthed tears that dripped from their edges. Saliva dripped from her mouth and mucus dripped from her nose. This wasn’t the tentacles’ mucus that defiled her beautiful face, oh no, this was Alfira’s own unsightly fluid.

If there were a mirror before her, just what would this female knight think of herself?


Its mucus glittering, a tentacle then held itself in front of her weakly opened mouth.

Moving slowly as it moved away the saliva covering the area around her mouth, it defiled her glossy lips. Once her lips were entirely covered in mucus, she smelled the acrid scent of blood.

Knitting her face due to the smell, she tried to move her face away from the tentacle.

However, her face could only move sideways to the extent that her neck would allow it to turn. All the less considering she was restrained.

Enjoying Alfira’s feeble resistance, the tentacle didn’t just defile her lips, but also the nape of her neck, her ears, and her cheeks.
