Inside the Cave of Obscenity

Her brain goes white at the suddenness of the situation, and she bit off the tentacle in a spur-of-the-moment reaction. She spat out the tentacle that had entered her mouth and glared at Frederica strongly. She calmed down a bit by biting off the tentacle.

She felt sick due to the mucus that had gathered in her mouth. When she entwined it with saliva and spit it out, she felt that her mouth was full of rotten taste.

"Get away from me, Frederica!"

As the captain who led a group of knights, she glared at Frederica. Her cheeks were dyed red due to the pleasure given to her while she was in a hypnotic state and watching a woman being violated in front of her, however, the intensity of her gaze didn't lessen.

And Frederica, who was glared at by Fiana was moving her body back and forth to match the rhythm of the tentacle piercing her lower body as though Fiana's glare and words did not reach her. She already climaxed many times.

Frederica's clouded eyes reflected Fiana's mad look, but she didn't see it. She was already drowning in the pleasures that the Black Ooze gave her, as though she didn't care about Fiana.

On the contrary, Fiana who voiced out strong words was bewildered.

Fiana, who did not expect to be ignored, was concentrating on her mana which was slowly recovering when she woke up from the hypnosis earlier.

If she used her magic, Frederica would――.

"Eh――"

At that moment when she was thinking. Her underwear was pulled. Frederica's body was covering her lower body, so she could not see it, but she felt a cold breeze in her pubic area and leaked out a puzzled voice to the sensation, which was different from the mucus tentacles.

The sensation from her genital area that was exposed and having her genital area and clitoris rubbed by the pulled-out underwear. It took her a few seconds to figure out what that meant.

"No――"

Stop it.

Before she could say so, the tentacle straightforwardly entered her exposed pubic area. Fiana herself was unaware, but while she was unconscious, her genitals were already wet due to the caresses. Her wet pubic area and the mucus tentacle touched and her vagina swallowed it without showing any resistance.

Frederica's saliva dropped from her mouth and stained Fiana's face. She looked up at Frederica in a daze, not knowing what she had done for a moment.

"Hii!? W-why!?"

There was nothing at all. This monster violated a woman. Fiana understood that. In truth, right now, it was still violating Frederica in front of her. However, her thoughts and common sense could not keep up.

It was something she could not even imagine, a human being violated by a monster. A monster was an enemy of humankind and to be killed. That should be―― unable to understand the reality of her being violated by a monster, Fiana flailed her body to escape the sensations she was feeling.

As she moved her hips up and down to free herself at least, Frederica's body lifted slightly. But that was all she could do. A situation where she was lifting Frederica with her hips could only mean that she was happily shaking her hips when viewed at a distance.

Fiana, who never thought of that kind of scene, was confused by the strong existence that pierced her vagina for the first time in a long time and shook her body.

More than anything――.

"Hii, no!? W-whyyy!?"

Shame came out from her mouth.

The tentacle that invaded her vaginal canal did not violently pierce all the way at once, but first slowly moved back and forth near the entrance. Gently open her labia, which was tightly closed, and stimulate Fiana with a movement that does not put a burden on a female body.

It was a movement that Fiana liked. Little by little, until she got used to it. Slowly conquering her body. Fiana liked that feeling.

Gently rather than violently. Slowly, as though melting into each other, then together would engage in sexual intercourse. She was bewildered by the tentacle that moved as though it was moving in the way that she wanted.

After gently rubbing the upper part near the entrance, the tentacle quickly retreated to the entrance area, and this time it poked the vaginal wall as though to scrape it. The tentacles then retreated to the entrance, rubbing the upper part again. However, the tentacle did not leave the vagina.

Slowly, it adjusted her vagina to the thickness of the tentacle.

It was as though the tentacle was remodeling her vagina to its size.

And yet, the gentleness with which the slime cared for Fiana's body was the exact opposite of Frederica, who was drooling on top of her as she was being violently penetrated. The difference was so great that Fiana, who was being violated, was almost confused.

But she couldn't afford to be confused for a long time. No matter how gentle the act was, she was still being violated by a monster. The shape was different from the penis Fiana had known, changing into various shapes.

It rubbed the upper part of her vagina and spread out to the sides, and then it goes deep into the vagina and stimulated the area behind her navel. It was staying there and moving itself to stimulate her entire vagina.

"N... o―― W-what is!?"

Inexperienced with such stimulations, Fiana raised a surprised voice and looked at her lower abdomen, where she and Frederica's chest were in the way. Fiana's confusion grew deeper and bigger in a situation where she could not see what was happening in her lower body, but she could certainly feel the pleasure in the depths of her vagina.

Her hips were twitching. She felt good. But the anxiety of not knowing what it was doing got in the way of her climax. In the first place, It informed her that she was feeling good even when being violated by a monster, but when her vagina was stimulated differently, she was surprised―― and at the same time, a short, rough gasp almost escaped her mouth.

Although not visible to Fiana, her hips seemed to have twitched slightly as the tentacle entered her, and she seemed to be having a series of small climaxes.

"Uu, kuh! Something like this―― Because something like this is――"

Little by little, the violent movements slowed down. Her confused mind finally began to recognize the sensations as pleasure. Her moans become louder and louder, and the trembling of her hips spread to her entire body.

Her fists were clenched so tightly that they were stained white, and her toes were curled up through her ankles to withstand the pleasure.

Her thighs were stringy as she tried to endure the sensation of penetrating her vagina, and her whole body was covered with beads of sweat that give off a different scent than the mucus of the Black Ooze. Her teeth that were clenched were not to withstand the pleasure, but an act of refusing her charming voice that was about to leak from within.

She closed her eyes tightly and moved her arms to get out of the restraint, though nothing was happening.

Her legs had already stopped rampaging and were trying to withstand the stimulation.

"Ahh, there. It feels excellent―― so good!!"

Frederica's cry reached the long ears of the elf. That voice was also a factor in disrupting Fiana's reason.

While being raped by an abominable monster, she felt pleasure. The woman in front of her affirmed the feeling, even if she tried to deny it.

Was it unpleasant? Or did it feel good? Even though she didn't understand, she still twisted her body hard.

Their breasts rubbed against each other, and her nipples, which should be protected by her clothes and underwear, emit a numbing sensation. The stimulation made her realize that her nipples were erect. She was being made aware that her body was experiencing pleasure. She didn't want to admit it, so she shook her body absent-mindedly, and Frederica shook hers in response. Just as Fiana found the act pleasurable, Frederica also found it pleasurable as her breasts swayed and their nipples rubbed.

In the lower half of their body, two asses wrapped in contrasting black and white underwear swayed as though to entice a man, and a mucus tentacle of the same size was stuck in their pubic area.

At first, the crotch part of their underwear was only moved to the side, but due to the two people's movements, their underwear that was hiding their asses, and even the anus entrance that should have been hidden was slightly peeking...

The two beauties could entertain a man from various angles, however, the Black Ooze treated them with the same behavior as before. It caressed their entire bodies, penetrated their vaginas, and released its semen.

Fiana was oblivious to this straightforward behavior. But that was not the case. The shock of being violated by a monster for the first time has stopped the female knight from thinking.

The strong desire to escape and the feeling of comfort that hid behind that desire.

While being swayed by those thoughts and feelings, she was breathing hard and rampaging to escape the restraints of the Black Ooze. As she exhaled raggedly, she couldn't tell if she was just exhausted or moaning, but sweat was pouring out of her body as her metabolism was boosted due to her moving violently.

Above all, if she put all her strength into her body like that, she would reluctantly tighten her vagina, and she would feel the sensation that she was being violated strongly and clearly.

As though to resist the pressure of Fiana's vagina, it moved deeper inside, then expanded and retreated to the entrance while being squeezed.

Then, slowly, little by little, the range of movement was expanded. At the deepest part, it tried to get closer to her womb.

She, Fiana, knew where her womb was and felt how far the tentacle had advanced. She was in a panic.

Little by little, the tentacle was approaching Fiana's womb. No matter how tight it was, the progress would not stop, and it would surely reach it.

It was a reality that was tantamount to despair for the elven knight.

The semen that dripped down her face still stained her cheeks. Its odor had passed through her nose and the information reached her brain.

It was the reality―― she didn't need to think about what would happen if the tentacle that was ravaging her reached her womb and what it would do once it reach it, she already knew what would happen.

"Haa, haah. Phew―― phew..."

She was trying to calm herself as she let out a short, quick, gasping breath. Tears accumulated in her eyes while watching the face of a woman, loosened in pleasure. The woman was moaning in front of her while being violated by a monster. The unrealistic scene brought tears to her eyes, and the fear that this would happen to her filled her heart and mind.

She tried to avoid that. She didn't want that to happen.

She desperately tried to hold on to her frightened heart that was about to give up. So she mustered up her courage.

Putting force in her vagina, She was delaying the tentacle that was invading inside her as much as possible, even if just a little, using her magic to escape the mucus restraining her. That was what she thought, but it was hard to concentrate her mana to release her magic.

There was little she could do by concentrating on the little mana she recovered though, but when she thought that she had constructed the spell with her little mana to release it, the tentacle suddenly moved inside her vagina. Moreover, the tentacles between Fiana and Frederica's breasts suddenly moved to stimulate her nipples and the tentacle that was stimulating her ear moved to poke its hole, interfering with Fiana as though it was timing it before she could fire her magic.

"Kuuh... kuh, fuu"

"Ahh, ahh, ahh!"

Her passionate breathing was about to leak. When she tried to endure it by clenching her teeth, Frederica's sweaty body arched backward. It was an orgasm.

She didn't count how many times she cummed, but it must have been a few times already. Frederica dropped to the laying Fiana, covering her.

That was also the second time.

Frederica's hot and passionate breathing shook Fiana's ear, and she felt Frederica's rapid heartbeat through her chest. Her body temperature, which was different from the slime, was a little higher than Fiana's, and it must have been due to having sex―― it seemed to give her a strange delusion.

Feeling Frederica's rough breathing, Fiana moved because she couldn't bear it. She tried to keep her ears away from Frederica's breathing.

It was an act to protect her sensitive ears, however, it attracted Frederica's attention, who had reached the point of oblivion after her climax.

Frederica must have thought that a delicious prey was in front of her.

Breathing rougher than before, she opened her mouth and got closer to the elf's ears in front of her.

"Hyuu!?"

Fiana, who had been busy enduring the stimulation given by the tentacles, let out a cute scream at the new stimulation. Her hips bounced, tightening the tentacle that had been moving back and forth inside her vagina. At the same time, the upper part of her vagina where one of her weak spots was located was rubbed strongly, and she screamed a little.

"F-frederica-san!?"

"Nnn―― ahh, mmmnn..."

"No, nooo...!?"

A weak scream escaped from Fiana's mouth. Her tongue, dripping with saliva, licked and sucked at every corner of her ear, and pointed the tip of her tongue to poke her earhole.

It was the same action that Frederica had done when Fiana was still unconscious, but the woman elf's eyes widened in agony at the passionate caresses.

Her body quivered, and her breathing turned into gasping.

Her tongue peeked out of her opened lips, which was pointed towards the ceiling.

The sound of her being licked directly was transmitted to her brain was echoing. She could not hear anything else. It was more stimulating than being licked by a tentacle. It was largely because Frederica's tongue licking her was more passionate than the tentacle, and she was alarmed by the sudden stimulation.

"Eh, nn―― This feels weird!?"

She didn't know what was weird. Fiana thought that Frederica's behavior was strange and tried getting away. However, seeing Fiana resisted by shaking her face, Frederica did not like it, she sweetly chewed not only with her tongue but also with her teeth and tried not to let go of her ears.

"Fuu, hii!?"

A weird voice leaked from her mouth.

Without worrying about the weird voice she let out, Fiana, who was bitten at her ears, shook herself and shed tears.

She climaxed. It was a clear reaction to anyone who saw it, but Frederica, who was also immersed in the afterglow of her climax, did not notice it. Even though Fiana cummed from her ears and her entire body stiffened, Frederica did not stop licking her ears. Rather, she resumed her sweet biting deluding herself to escape her convulsions after her climax.

Gently, even lovingly, she bit Fiana's ears, while breathing roughly.

Fiana screamed in agony as she listened to the sound of her ear being licked and Frederica's ragged breathing directly to her ear. Thinking it was strange that her ears were so sensitive.

She had her ears teased by the men she had slept with in the past, but she had never had such a reaction. She thought it was a dirty place, no matter how intriguing the elf's ears were. They were rubbing it with their fingers, breathing on it lightly, and licking it. But Fiana had never been licked with such passion, due to Frederica's actions, the stimulation from her genitals was giving her the impression that its action was pleasurable.

As a result, Fiana's ears, which were one of her erogenous zones, were passionately caressed as the tentacles moved, and she thought she was climaxing with her ears. The first time she had ever climaxed with her ears, Fiana's confusion was compounded by the fact that her ears were being caressed while she climaxed, causing her body to lash out in a way that was different from escaping her restraints.

The feeling of fear that occupied her heart was also replaced by something completely different.

She was afraid of being licked in her ears anymore.

With that in mind, she made her entire body rampage to escape from Frederica's tongue, however, her vagina was pierced powerfully. The tentacle, which was slowly expanding her vagina, pierced her womb strongly.

"Hi, hii!?"

A trembling shriek leaked out from her lustrous lips. Her ears were licked and her genitals were stimulated. Her head, confused by the two stimulations, couldn't endure it and asked for help in the form of a scream.

Fiana's body trembled, leaking out a powerless scream. Rather than a climax, she was shivering from fear. However, the next thrust, which had been caressed for a long time and exposed to new sexual sensations, gave away and trembled from climax.

Her mind was confused and she couldn't figure out what was what anymore.

Confused, her body rampaged frantically, but the restraints on her arms wouldn't let go. She tried casting a spell, but her concentration was interrupted by the stimulation from her ears and genitals.

"Fuaah!? T-thereee!"

A new tentacle wrapped around her chest, which looked like two large fruits, and stimulated it. It was like milking livestock, just like with Frederica. However, it was not a strong and painful stimulation like with Frederica, it was a gentle movement that stimulated everything from the base to the tip of her nipple.

This was frustrating to a body that had already reached its climax, and Fiana now swayed her body of her own volition. She unconsciously shook her body and rocked her hips.

Then, the tentacles stimulated her weak spots.

Her hips bounced, and the tentacles stimulated different parts of her body again. She felt so good that she unconsciously moved her hips to escape the feeling while her mind was clouded by pleasure.

It was a vicious cycle. Her movement to escape the stimulations helped the tentacles to act more, her actions led to the opposite. Her movement, just like Frederica's, was like she was inviting it. She could not think about anything else when she was being poked in her weak spot, she tightened her vagina and felt the shape of the tentacle inside.

The female knight didn't seem to realize that this was the very act that she was expressing her disgust over. Her vagina was pierced while her ears were licked, and she let out a gasp and accepted the tentacles.

The trembling of her body gradually increased. At the same time, the movement of the tentacles also intensified.

"Ahh, aahh... Ahh――!?"

A suffocating voice leaked out from her lips while her tongue was sticking out. Not enough oxygen. Her tongue was thirsty and in pain. She could not stop her tears from flowing.

Even though she knew that, she felt as though her body was no longer her own. She knew in her mind what she was doing, but could not do anything about it.

She was scared.

She was so scared that her body started trembling.

Fiana realized that she couldn't scream anymore.

It would feel better. How good would it feel to have semen pour out inside her vagina and womb while being swept away by this comfortable feeling? It almost made her think about it.

As Fiana shooked her head and tried to ignore her thoughts, Frederica's stretched her hands to restrain Fiana's face. Her ears were bitten, licked, and sucked. Her other ear was scraped lightly by Frederica's fingernails while rubbing it. The stimulation she felt was good too.

Everything felt good. She didn't know what was what anymore.

However.

"Aahh, ahh―― Aaaahhh!?"

She screamed so loud that her throat hurt, and her body convulsed. Her thoughts turned white, and she almost let go of her consciousness due to exhaustion and climax.

"――Ahh, ahh... Ahh, f-feels good..."

Exhausted, the sound that was echoing from her ears didn't stop.

"Hyaah... N-no, staph ith... alweady."

A weak voice echoed, whether it made sense or not. Her body shook as the tentacle was still piercing her, and Fiana was helpless due to the afterglow from her climax.

She continued to sway like a doll, and after a short pause. She felt a hot sensation from the deepest part of her vagina.

Even though she was in a confused and near fainting state, she could still feel the sensation.

Ejaculation.

The hot, hot liquid was being expelled into her womb.

Feeling the heat inside her, Fiana shed tears. While still feverish, she shed tears and let out a sobbing voice.

A monster ejaculated inside her. Her womb was defiled. While shedding tears in despair, she could not wipe the tears that were flowing due to her limbs being restrained.

"Uuu... Fuu―― Uaaahh...?"

Frederica's soft hands patted her cheeks to comfort the crying Fiana. She gently stroked it to feel its outline, then Fiana turned her gaze toward the female adventurer. Her eyes met Frederica's, who had stopped licking her ear.

"Are you crying?"

Her voice sounded as though she was making small talk. She should have understood what was going on, but there was no sense of urgency or fear in her voice.

She was being violated, orgasmed, and having semen released into her womb. However, Frederica looked at Fiana as though she didn't care about anything.

She thought she had regained some of her strength. With both arms on the bed of flesh, the upper body was raised, and the posture was as though she was looking down on Fiana from the beginning. Her upper body―― The tentacles that were wrapped between the chests were released and disappeared as though they were swallowed by their chests.

(Now... And now, with this...)

"It was not over yet though."

And as she said that.

"Eh?"

Fiana raised a questioning tone from her clouded voice. Immediately after, the tentacle that had been buried inside her vagina and released the sperm start moving again.

"...Eh? W-wh... y"

Her body, smaller than Frederica, began to wiggle as it start thrusting inside her again. Her heavy robe that had absorbed sweat and mucus rubbed against Frederica's clothes, making a rattling noise.

"Uu―― Hii, It's, a lie... because!?"

Slowly, the speed and strength of each thrust were increasing. Her vagina that had already cummed and leaked love juices hold the tentacle more firmly than before, and the rubbing was making an obscene sound.

Fiana, though she could not see it, seemed to hear it.

"Nn, ahh... unn, that spot felt good..."

Frederica was already starting to let out a gasping voice. Fiana saw Frederica as though she saw something unbelievable.

She was starting to calm down similar to when she first regained her consciousness. However, the emotions in her eyes were completely different.

Her eyes were no longer filled with disgust.

Instead, they were filled with fear.

"Because once you ejaculate, it's usually..."

There was a clicking sound. Fiana didn't realize that it was the sound of her teeth clacking together. Her breathing, her nasal breathing, became more erratic with each thrust.

Fiana's body accepted the pleasure the tentacles were giving her more easily than before, and her disgust faded and her sweet, hot breathing began to escape from her mouth. ――She was helpless.

Feeling fear. She was helpless. It was not because she was bound and could not resist. It was because her body was slowly accepting the monster.

Frederica looked down at Fiana, who had an expression that could be described as despair.

Frederica thought that maybe she had a similar expression when she was violated by this monster for the first time, and when it was released into her womb. There was a tingling feeling running down her spine.

It was not a feeling of superiority.

Frederica felt good when she thought that this white and beautiful knight would also be dirtied in black.

"You're, an idiot, Knight-sama..."

She muttered while speaking roughly.

Knight.

It was a title she uttered with mockery, far from respect.

"The monster should end in one time, isn't it?"

"――Ah"

She looked at Frederica saying such things with eyes seeing something unbelievable.

In addition, tears flowed from her eyes. Unlike before, it wasn't tears of sadness nor tears of joy.

...She couldn't help but cry due to despair. Her heart was about to break.

It was ejaculated in her womb. But it was only once. The odds of having a baby in a single ejaculation... would be high due to it pouring directly into her womb, but it was not absolutely.

But what if it was repeated over and over again?

What if it ejaculated inside her many times from now on?

This monster manipulated tentacles.

She was sure it would ejaculate directly into her womb, just like before. That was what her instincts told her. So Fiana's stunned face looked at Frederica's, no, behind it, she was looking up at the ceiling while shedding tears.

"Ahh..."

The monster should end in one time, isn't it?

She was thought of that many times, then she ignored it. When it disappeared from her mind, she thought of it again, over and over.

Then how many times?

How many times it would need to ejaculate directly into the womb for it to finish?

While being pierced by the tentacle, she looked around like a broken doll. This place, which was probably the deepest part of the abandoned mine, was covered with black mucus... Black Ooze liquid.

In other words, it was a monster with this much mass.

...She didn't think it would end in just two or three times. She could not believe it.

She believed that it would ejaculate until she get pregnant―― until her womb swelled.

"Ha- haha..."

What would happen if she just accepted its semen?

Would she get pregnant?

Impregnate, gave birth to a monster child―― she would get pregnant again. This repetition. Not as a woman, not as a mother.

She would be treated as a nursery, as a tool for giving birth to children.

Fiana's eyes that had no light saw Frederica.

――It seemed to be good. The female adventurer was moaning, looking down on her.

"No"

It was a small voice that no one could hear.

She knew it was useless, but she moved her right hand to escape the restraint.

Her Left hand, both of her feet, her entire body. She moved them. It was no good though. She couldn't get out.

Did the slime take it as her resisting? The Black ooze made the tentacles move violently. Her weak spots that Fiana told the slime while she was still asleep. Her weakness, weak point. A place where she could not help but react. Not just her vagina. Both arms, armpits, legs―― only the breasts were being caressed by Frederica, and even though her mind could not think of anything else, her body reacted.

Her rough breathing escaped from her nose. Her passionate voice could be taken as a charming voice.

Sweat overflowed from her entire body. Cold sweat―― cold sweat that chilled her soul to her core. However, even such sweat was nectar with a mellow scent compared to the bodily fluids of the slime, but the tentacles licked her sweat.

"No"

Her voice became a little louder.

"...No"

Then her voice got smaller.

"Nooooooo!!"

She screamed.

A woman screamed, not a knight.
