Inside the Cave of Obscenity

Chapter Volume 1 15: Slime Nest End

Fiana flailed her entire body violently and tried to get out of restraint.

She gathered all the magic she had recovered in the short time she had been here to increase her physical strength, but she had less magic than she thought. Her resistance was weaker than when she had tried to break free earlier.

Fiana, who was rampaging desperately, was unaware of it and would not want to admit it. However, when it had ejaculated into her vagina ――her womb―― earlier, albeit briefly, from the heat. She climaxed.

No matter what her body did, she would not accept a climax that was filled with nothing but disgust. However...

She climaxed. The moment when her mind was still clouded due to the climax. At that moment, the Black Ooze had stolen Fiana's mana, an elven knight skilled in using magic.

Like Frederica and Satia, it took away their mana at the moment they climaxed.

Because of that, Fiana's resistance was reduced to a small amount. However, it was only a moment of climax. Moreover, Fiana, who had been upset by being violated by a monster, did not notice it.

In the first place, the monsters―― especially the Black Ooze, which was only a subspecies of slime―― should not be able to use magic and absorb mana.

Fiana rampaged just to escape.

"No, nooo!? Stop... Stop, stop it!!"

Rejecting it. Due to her rampaging, it was putting all its strength into her entire body, it was the same with her vagina. Despite her voice and expression, her vagina squeezed the tentacle with its entirety as though urging it to ejaculate.

If it were an ordinary man, he would have ejaculated and released his semen into the vagina with that alone.

However, the Black Ooze was a monster.

It thrust its tentacle into her to try to satisfy Fiana without losing to her tightness.

The more a woman felt good, the more she would be ready to get pregnant. To keep up with the desperately tightening vaginal pressure, the Black Ooze instinctively manipulated its tentacle to stimulate the entrance to her womb and the area around it.

It didn't just thrust in. It spread up and down, left and right, sometimes strong, sometimes gentle, its movements were not repetitive, and it even change its thickness, so it could stimulate more skillfully than the men Fiana had experienced before.

It was an unbearable poison for women like Fiana and Frederica, who had some experience with men.

After all, it felt good.

Stimulated by its incredible movements, it made her surprised at first, and then when she got used to it, it made her scream in delight. The entrance to her womb was getting poked and the area around it was being licked while it stimulated the entrance of her vagina and the back of her clitoris, the tentacle did not stop and expanded larger then gets smaller to stimulate her vaginal passage.

"Sto―, hii!?"

Fiana's body, which had been rampaging, stiffened.

While dripping tears and saliva, she desperately clenched her teeth and suppressed her cry. She didn't realize that the act of enduring it would accumulate her sexual desire more.

"Aaaahh―― Nn... C-cumming..."

Unlike Fiana, Frederica was freely saying that she had reached her orgasm while relaxing her expression. It was not a climax that would make her lose her mind, but it would make her hips tremble and squirt, wetting Fiana's lower body.

Fiana's white underwear became wet due to her juices and the Black Ooze's mucus, which became even wetter and transparent.

Feeling the warmth that was different from the Black Ooze tentacles, Fiana shook her hips frustratingly. Breathing that was different from her. Body temperature. Body fluid. ――Various elements envelop the female knight's common sense.

She almost lost track of what she had thought to be common sense until today.

She almost lost consciousness in this abnormal situation.

(Why...)

The tentacle that had still not reached ejaculation repeatedly poke her vagina that was repeating its violent tightening and convulsions, proof of her climax nearing.

"Don't―― No, no... Stop."

Her words of refusal had no power. Unlike moaning, she was exhausting her physical strength rapidly due to her violent and disturbed breathing. Before she knew it, her resistance that was trying to shake off the restraints stopped.

While breathing roughly...

"Ahh, ahh, there―― There, it feels good there"

Fiana heard a moaning voice that was not trying to hide the pleasure it was feeling. She wanted to close her ears, but could not even do that. Now that even her small resistance had been sealed and had lost her strength, she could not think of anything.

Above all――.

(Why something like this is...)

"Fuu――!!"

She clenched her teeth and refused to moan. That was the thing that Fiana could do right now. However, her body that reached a shallow climax had trembled slightly, informing its condition to the Black Ooze and Frederica.

"Y-you――! You climaxed didn't you!?"

"...I-i had not!! I didn't―― Hyaauuh!?"

She strongly denied it. However, as she opened her mouth to deny it, the tentacle inside her licked her womb's entrance and its perimeter as though it was aiming for it. The tip of the tentacle stimulated it with such dexterity that seemed to give Fiana an impression that many tentacles were licking it.

She let out a wild scream at the new stimulation.

"Hii! Stop―― Stop that!?"

She struggled with all her strength, but her resistance was even weaker than before.

However, due to the fact that she was putting all of her strength into her body, her vaginal tightening increased, and strongly felt the foreign matter that was moving inside her vagina. Fiana shook her hips again, feeling the entrance to her womb being licked even more vividly.

She wondered what she was doing now, what she was trying to do, and why was this happening?

The strange smell, the lack of oxygen, and the unrealistic situation were making her lose track of what was she was supposed to do.

Her mind tried to give up thinking.

Still, her hips, her entire body was reacting to it. It tightened her vagina so that she could feel the tentacle that was giving her pleasure more, and it spasmed repeatedly to show the degree of pleasure she was receiving.

"Hii, hyaahh―― ahh, ahh, ahh"

She could not close her mouth once she opened it. She tried desperately to close it and clench her teeth, but her breathing escaped through her lips and between her teeth.

Fiana was in despair and in pain. She almost cried, not at the current situation, but her reaction. Her eyes moistened, and her gaze up at Frederica wavered in tears.

"――nn"

"Nnuu!?"

Frederica, who was looking down at Fiana, leaned her body to relax her arms and kissed Fiana. Fiana raised a surprised voice at the kiss between them while being violated by a monster, and shook her face to try to escape, but Frederica moved her head and did not let her lips escape.

She just pressed it on her lips. It was not the same as a man's, but the soft lips of a female, the wild breathing during sex, the raised body temperature, the small trembling body, the rich breasts that were overlapping.

Unlike Fiana, who just opened her eyes in amazement, Frederica... licked Fiana's lips, which were showing a pleasant reaction in her body.

"!?"

An excellent knight with talent and experience whom Frederica could not compete with, Fiana, who was shutting her mouth, trembled slightly.

It was clearly a reaction to something different from the pleasure that the Black Ooze was giving her.

It was a reaction to Frederica's tongue.

Feeling good about it, Frederica slowly increased the intensity of her tongue movements, little by little. She licked her lips, then moved to trace the edge of her lower lip, and then to her upper lip.

After licking her lips in the same way, she now poked her lips with the tip of her tongue.

"Mmm!? Mmmpff, uuu!?"

Fiana held her breath to show her resistance to Frederica's tongue movement.

It was something she couldn't think of, such as kissing between females. While looking frightened at Frederica who was doing such a thing, she was desperately closing her mouth.

However, her disordered breathing put a strain on her body, and her nose breathing quickly became rough.

"Fuu, fuu..."

Filling her lungs with oxygen through her nose. When she inhaled the offensive odor similar to rot from the Black Ooze and the scent of a woman from Frederica, she felt lightheadedness.

Meanwhile, the tentacles did not stop moving and continued to stimulate the two beauties. The tentacles constrained them to the base of their legs to hold back the trembling of their hips, and their breathing became ragged as the tentacles pushed up against their vaginas.

Frederica spilled hot breath and saliva from her mouth and stimulated Fiana's mouth with her tongue.

Fiana, on the other hand, closed her mouth and breathe only with her nose.

It was not like she was going to stay like that for very long though.

"Haahh!―― Ahh―― Nnmmphhfuuu!?"

Finally, she opened her mouth in a daze due to a lack of oxygen but when she opened her mouth to take a deep breath, Frederica's tongue entered her mouth as though she had been waiting for her to do so.

There was nothing she could do to resist it.

She tried to bite her tongue, but it was no use as her tongue was entwined with her own, and saliva was poured into her mouth.

Frederica's saliva seeped into her dry throat as Fiana shouted words of rejection. It was not a matter of will, but instinct, and she swallowed the saliva. As she swallowed the saliva as it was sent to her, her throat was gulping it.

It had a strange taste and smell.

It was the taste of the Black Ooze's semen that was released on Frederica's face. Fiana didn't know that, but her throat went up and down. She let it happen.

"Nn... ahh, ahh..."

"Nn... fuu..."

Between their lips, the saliva that Fiana could not swallow overflowed and stained the female knight's mouth. The Black Ooze semen that was on Frederica's face clung to Fiana's face.

They were both immersed in the mouth-to-mouth kissing as they brought their faces together. The two women were kissing each other under the unusual circumstance that only the upper half of their bodies responded to the stimulation from their genitals.

Slowly, Fiana's resistance was disappearing. She could only twitch as she was attacked by the tentacles, and showed a reaction of that of a woman.

(Why)

For a long time, that was the only thought she could think of.

Her breathing was uneven as she was strapped to the bed of mucus. Fiana and Frederica's hot breathing leaked through the gaps between their overlapping lips.

(...Why does it feel so good...)

It was the time after Fiana was defeated by the Black Ooze and before she woke up. She doesn't remember it, but it was because she was being violated the whole time. Endlessly.

Because she was trapped in a dream by Frederica's magic, answering the Black Ooze's caresses and whispering her love. She was telling it what she felt, what spot she was weak at. She was teaching it.

Fiana, who did not remember any of that, shed tears at herself, feeling good while being violated by a monster and kissed by a female.

She couldn't get out of this hell alone so she could only shed her tears.

After some time, Alfira gained consciousness.

The light had returned to her eyes, perhaps her energy had recovered slightly after taking a rest. Looking around her with a sharp gaze, she saw that her surroundings had changed a lot since before she fainted.

First, there were more people. Frederica and Satia. Satia was strapped to a bed of flesh like the one Fiana was trapped in, and she was twitching occasionally. The expression on her face was weak, indicating that she was probably going to faint as Alfira had been earlier.

Still, the tentacle that entered the hairless pubic area thrust up the fleshless limbs like a doll.

The enemy was a monster. An abominable enemy. An existence that must be defeated.

She shook her hips to a monster, asked for forgiveness, sought a climax, and stretched her tongue into the rotting liquid.

She bit her lip forcefully, almost reminding herself of her weak self. She shook her head, but finally, Alfira regained her senses―― not from sleep, but from a stupor, knowing that, the Black Ooze resumed its actions.

The tentacles had entwined with the top part of Alfira's foot, while she was still sitting in the mucus.

"Hii"

A trembling voice escaped from her mouth.

Biting her lips to hide her weakness, her escape from the mucus tentacles got delayed.

The mucus that covered the floor that came into direct contact with her skin was uncomfortable, and she pulled up her underwear with trembling hands.

And messed up. Black ooze mucus... Alfira herself would deny it, but her underwear that was soaked in love juice touched her crotch. She hurriedly finished putting on her trousers and underwear, even though she was struck by a wet sensation. As though waiting for her, the mucus tentacle just lightly tapped the top of her foot.

It was as though it was having fun with Alfira's reaction.

She then slipped down her rolled-up clothes and hides her bare breasts. As she did so, her pointed nipples rubbed against her mucus-soaked clothes, causing a sharp stimulation, but she pretended not to notice and put her clothes back on.

She was wearing only a thick jacket and trousers, and hand and foot armor.

The miserable appearance of the defeated knight itself almost brought tears to her eyes. But she managed to hold back the tears, as not to admit that she had succumbed to the monster and managed to put up with it.

She retreated while rubbing her legs together.

With her right hand, she held her trousers to prevent them from slipping down, and with her left hand, she grabbed her chest to prevent her jacket from being taken off. Alfira retreated, curling her body as though she were an innocent girl running away from her rapist.

Her eyes could not see Fiana, who was also in the same area as her, but only the mucus tentacles that were chasing her as she crawled back with frightened eyes.

Her frightened eyes were alluring and definitely would arouse her attacker.

That was if it was a normal rapist.

However, the tentacles were neither impatient nor aggressive and simply chased Alfira. Finally, her back touched the wall. Normally, it would touch the rock wall, however, it was covered with mucus.

Alfira turned around in a panic, almost giving up that she could not escape.

However, as though to shake off her resignation, she leaned her back against the wall and tried to drive the tentacles away by flailing her legs.

"This, this!"

It was a loose, weak kick.

However, it was the best Alfira could do to resist.

Her resistance was easily caught by the mucus tentacles. First, it caught her right foot, then her left foot.

"No, nooo!? Release―― release me!"

A weak woman's voice almost leaked out not of a strong knight, and she hurriedly glared at the mucus tentacles with strong words.

However, the tentacles that were trying to catch her were not only at her feet.

Suddenly, a tentacle appeared from the wall of mucus that was touching her back and caught both of Alfira's arms that were holding her clothes.

"Hii"

A small scream leaked out, and the Black Ooze tried to pull her legs together forcefully as she sat down.

When she pulled her arms with all her strength to resist it, something touched her fingertips through the back of her hand.

When she turned her gaze at it, what she saw was a sword buried in the bed of mucus. It was a common steel sword issued to knights. It probably belonged to the knight who was swallowed by the Black Ooze.

As she tried to reach for the sword buried in the dark mucus, the tentacles grabbing her legs strengthened to prevent her from doing so. Her legs were pulled away to prevent her from reaching the sword, but she managed to hold on and crawled towards it with only her arm's strength.

As she lay down while her face was on the ground, she let go of the hand that was holding her clothes and grabbed the rock bulging from the mucus. She put some pressure on her fingertips and managed to resist the tentacles attempting to pull her.

She breathed out a sigh of relief. However, there was no time to feel at ease.

The tentacles grabbed her trousers, which had loosened due to her not grabbing them, and pulled them down at once. Again, as before, her skin was exposed up to her knees. The only thing protecting her genitals was her plain black underwear. Her underwear, which she had used because stains would not be noticeable, were devoid of any feminine touch.

She noticed that her trousers had been lowered, and Alfira's cheeks were dyed red shamefully that was different from anger.

"Let go !!"

When she shook her legs to struggle, her chest shook greatly under her jacket, which was smeared with mucus and stuck to her skin.

Her wet clothing showed its movement well, and also reflected the stiff and detailed nipple on top of it.

Her breasts were so lush that they rippled, and her nipples felt the sweet shock of the movement. She resented the fact that her body perceived this movement as a tingling pleasure on its own.

Tears well up in Alfira's eyes.

Even though she was trained as a knight, Alfira was still a woman. She lost her virginity to a monster and was violated. Her heart was not strong enough to endure that. When and where was the boundary... It wasn't strange if her last line of defense broke.

Reaching for the knight's sword buried in the mucus, was her goal. The tentacles reached her defenseless healthy ass.

Alfira, who was focused only on the sword, didn't notice it. She was just reaching for the sword desperately, hard, as though clinging to it as her last hope.

Little by little, she could see her fingertips approaching the sword. Just a little more. Just a little more. Her other arm that was different from the one reaching for the sword trembled slightly, resisting the force of the tentacles. Her face turned red from overexertion. She held her breath, desperately resisting―― and yet, the Black Ooze did not back down.

To further humiliate Alfira, who showed such resistance, her black underwear, the last defense protecting the lower half of her body. It hooked its thin tentacles to both sides.

Although she would strongly deny it, the uncomfortable feeling that she was accustomed to its touch made her feel scared. She clenched her teeth, wondering if it would do something to her again, but she didn't turn her gaze away from the sword.

No matter what it would do to her, she must keep holding the sword in her hand. She reached out with that determination, and her underwear was pulled down at the same time.

Her rich, plump ass was exposed. The skin was white without a trace of ooze, and the shape was tightened by years of training. Her ass was exposed, but Alfira didn't scream one bit.

She clenched her teeth with even more force and suppressed her shame.

Definitely. She felt it.

It was looking at her ass. She was strongly aware of it.

But still, she tried her best to reach for the sword, and her fingertips touch the hilt. But at the same time, her shapely ass was split open by multiple tentacles. What peeked out was a constriction that should be hidden more than her genitals. Her anus. A part of her body that had never been seen by anyone before, not even by herself. The skin around it was white without being exposed to the sun, but it was a dull brown color. It could almost count the wrinkles on her hips, and a voice of refusal nearly escaped her mouth.

She swallowed back her scream. Then finally, she was able to hold the sword in her hand.

It didn't change anything.

However. She relaxed when she got a weapon to resist. It had become loose.

At that moment, the tentacle that was grabbing her foot strengthened. Alfira's relaxed arm couldn't resist the force, and she was pulled back to where she was.

"Kyaa!?"

Alfira screamed like an innocent girl and slid on the mucus. Keeping the sword in her hand.

She clutched it to her chest as though it were more important than her own life, but she could not resist and the tentacles pulled her down.

She was pulled near the mucus bed where Fiana and Frederica were.

There was also the bed in which Satia was.

――All four of them would be violated.

Yes, Frederica saw Alfira, then thought that. She continued to climax, resting her entire body to Fiana underneath her and breathing while her shoulders go up and down. The fact that she looked like she was performing so well was probably because she's been moaning with pleasure. The look of satisfaction on her face was somewhat frightening to Alfira.

Fiana was...

"Alfira, use that sword to slash the tentacles..."

When she saw the sword in Alfira's hand, she said it in a weak voice. However, her voice still had the power of her will. A voice of hope that hadn't sunk into despair yet.

As she was told, she held the sword in her right hand so as not to drop it. However, the tentacles entwined with the blade and tried to steal the sword from Alfira.

However, the tentacles that entwined with the blade freeze in a blink of an eye. What she thought was the sword provided to the knights was in fact the sword that Fiana was using... Fiana's mana still remained on the sword.

That was the reason why the Black Ooze left in there was to take away its mana because the mana still remained there. A mere knight's armor and weapon without a shred of magic, like Alfira, was thrown away somewhere in the abandoned mine.

It was lucky. It might be a miracle.

Once she realized that this knight's sword contained the magic of freezing, Alfira's actions were swift.

She swung the sword, first, she froze the tentacles that were holding her legs and crushed them. As soon as her legs were free, she slashed the mucus that was holding Fiana's right wrist. The mucus also froze and shattered.

At that moment, the Black Ooze, realizing that Frederica was in danger, lifted her to protect her. Before the tentacles, which were a bit delayed, started moving, she swung the sword on the tentacles that were restraining her elbows. Fiana crushed the frozen mucus with all her strength.

"The sword!!"

Her voice was full of power.

She had been moaning from pleasure and despairing until a while ago, but even so, if hope came in front of her, she would have more power to get the job done.

Fiana grabbed her sword in her freed right hand and froze the mucus on her left arm, crushing it and freeing both her legs with the tip of her sword, dulled by fatigue.

Finally, at that stage, the Black Ooze began to act. Countless tentacles appeared around Fiana and Alfira. When she checked the tentacles, she noticed that Frederica and Satia were not around. The reason for the delay in the tentacles' reaction was to let them escape farther away.

"Alfira, can you run!?"

"N-no..."

Fiana, who heard that, was not a helpless woman like before. She sucked up the mana left on the sword and recovered hers for the time being until she could move.

It was her mana. Fiana could make the best use of it.

When she heard Alfira's reply, she turned her gaze to Frederica and Satia.

The moment just now. And from her experience in this abandoned mine, she could tell that this Black Ooze was treating Frederica and Satia specially. She didn't need to think about why the monster was keeping them around without killing them―― considering the humiliation they had just endured.

Biting her lip, she checked her surroundings and walked up to Alfira. Then she turned her arm around Alfira's thin waist.

"!?"

Alfira let out an inaudible scream.

Fiana held Alfira aside with a strength that she could not imagine from her small body and threw the sword in her hand toward Frederica. Pointing the tip of the sword and releasing it with a deadly intention.

As though to block the momentum of the sword, tentacles extended like a wall. But the mana contained in it, though small, froze the tentacles and caused some of them to shatter.

In the end, it didn't reach Frederica, but the Black Ooze, as Fiana had predicted, did everything in its power to protect Frederica, and in that instant, she succeeded in escaping from the passage at the far end of the abandoned mine.

Holding Alfira, who was taller than her.

"Nn... ahnn"

However, without worrying about it, the Black Ooze resumed making children with Frederica.

Frederica, who suddenly gave up after Fiana threw her sword at her for a moment earlier, however, her mind, blurred by the climax, could not think of anything else now.

――The Black Ooze did not chase Fiana and Alfira.
