Inside the Cave of Obscenity

Chapter Volume 1 13: Slime Nest 3

However, that did not mean that the tentacles would weaken or even stop their attack.

Her body swayed in the air as it was inserted inside her, and her breasts, which were covered with mucus, moved up and down, making a wet sound through her underwear. Her nipples, which were already erect, were now erect and can be seen through her black innerwear.

"――Ahh, n-not t-the―― re"

A tentacle as thin as the tip of a pinky finger was coiling on her nipples. Her breasts were handled like a cow being milked, and her nipples were pulled upwards as though she were suspended from a cord.

It was as though she was being milked at the air, defying gravity, and the pain she felt from her nipples made her turn her gaze to her chest.

(This is...)

Unusual treatment. It didn't treat her as a human being or a woman... But treating her like a toy and shattering her dignity.

And yet, what she felt was not pain.

The depths of her womb tingled, and she struggled to move her hips in time with the tentacle's insertion, even though she was in a precarious position of floating midair. Her body reacted to feel better.

That was very―― good.

"Mo, re... More, strongeeer"

She felt that the speed of the tentacle that was thrusting inside her increased slightly. The tentacles that were squeezing her breasts also increase in strength, and her nipples were also stimulated by coiling around the areola. Not only with the tentacles but also her sensitive nipples and skin was rubbing against her underwear were unbearable.

She was being violated while still clothed reminded her of the first time she encountered this monster, stimulating her humiliation.

At that time―― It was even worse. Whether she cried or screamed. She was violated all night. It was unpleasant, stinky, nauseating... She had a traveling companion inside the slime, she cried and begged for forgiveness, unable to avenge them due to the pleasure she was being given.

When she remembered that time, she felt a heat building up deep inside her waist, near the entrance of her womb. It was coming. Before she could even think about it, she moved her hips to guide the tentacle to that spot.

That was where she felt the best. She didn't care about morality or dignity. As she led the monster's manhood to a place where she could feel so good and forget everything, she saw white liquid crawling up through the black mucus.

It was semen. It was not the same as a human being's, but it was a magical fluid that could certainly impregnate a woman like Frederica in one shot.

If it was poured inside, a woman would get pregnant. A monster. The enemy of mankind. Abominable evil.

Impregnate.

She would get pregnant.

She would give birth to monsters again.

When she thought about that―― Instead of rejection, a scream of joy escaped her throat.

"Stop it!? There, no... no!!"

She screamed like a little girl, like a virgin. It was only for conventionality though. Both Frederica and the Black Ooze understood this. She happily grabbed the tentacle that would be giving her the magic liquid to bring it further inside. If she didn't like it, she could use magic to escape.

Burning its tentacles, she could escape. That was how much mana she had recovered.

The Black Ooze understood that, and Frederica knew, but she could not escape. She would not escape.

Because, it was because――.

"Nn―― Nooo, aaahh!?"

Her hips trembled strongly, again and again. The entrance to her womb opened up, the magic liquid that was released as it pressed against it, allowing it to enter. Her womb, now long accustomed to this, opened itself for the Black Ooze’s ejaculation.

It entered the entrance of her womb and directly violated the womb that was used for nurturing an offspring. She felt a sharp pain as the walls of her womb were violently poked, and her throat let out a genuine scream.

"It hurts, it hurts." When she said that, the tentacle stimulating inside her womb stopped being rough and changed to licking motions instead of poking. The mucus tentacle licked and scraped the fluids that were overflowing there.

It licked the places that could not be cleaned by a human finger. She was so embarrassed and felt so, so good. She was gently stimulated in places that no man could reach, it felt even more gentle than when she was being violated earlier.

"Wa, it. Wait, wait! Now, not now..."

"No" she said. She was about to say it, but the intensity of the penetration prevented her from saying it.

She didn't know what was wrong with her. Still, Frederica was interrupted when she gasped and desperately tried to say a word of refusal. The tentacle of mucus stimulated her vaginal walls. Its shape was not always consistent. The tentacles could change shape. Its shape changed from one moment to the next. It moved like a snake inside her vagina at one moment then it stimulated Frederica by moving in various ways, such as below her navel or on the side of the intestinal wall, as though driving a stake up and down instead of inserting back and forth.

It was not consistent, so even though she were trying to endure it, she would not be able to, and if it found a weak spot that even Frederica didn't know about, it would focus on that spot.

It was not about pleasing Frederica, but about examining the body of Frederica's... a woman's. There were only four women that the Black Ooze have at the moment. That was why it was going to examine the bodies of those four women and use them as nurseries for the future. That was all it was doing.

After all, there was no such thing as affection or attachment involved.

No matter how much Satia whispered her love to the Black Ooze, or how much she serviced it, Frederica knew that its behavior would never change from a certain level. She understood that.

In the end, this monster would only give them pleasure and nothing more.

It was both exclusive and catastrophic... She knew that the right thing to do was to seek help from Fiana and the others and get away from this place, but she could not choose that.

"Th-, uu. T-there―― There, g-"

The top of her vaginal wall, on the opposite side of her clitoris. Pushing up from the inside, it constantly informed her of new weak spots.

"Aaahh―― Ooaaahh!? Ooh, aaahh..."

The stains spread on her trousers. Frederica's ears hear a rattling noise in her trousers that had changed to a darker color.

Her hips twitched while she was in an unstable position in the air, and she almost fell to the ground. But, several tentacles supported Frederica's body. They wrapped around her waist, lifted her hips, and held her in the air.

It wasn't because they were trying to keep Frederica from falling.

As she was saved by the tentacles, Frederica tried to say thank you for a moment but stopped. This was because, with her hips locked in place, her body was restricted from shaking her hips to dissipate the pleasure.

The spasms in her hips were forcibly suppressed, and the new weak spot she had just discovered was thrust up by a tentacle without a moment's hesitation.

She didn't know because it was hidden by her trousers, but it was a violent push that her plump lower abdomen was slightly lifted. The untouched clitoris popped out of the foreskin and rubbed against the underwear smeared with love juice and mucus.

The thrusts were so violent that her fleshy lower abdomen rose slightly, though it was hidden by her trousers. The untouched clitoris popped out of the foreskin and rubbed against the underwear smeared with love juice and mucus.

"Aahhh, no, don... I-igii――"

Her upper body rampaged to disperse the intense feeling, but her fixed lower body could not be shaken no matter how hard she moved. Even her convulsions were suppressed, her vaginal wall was pierced, and her clitoris rubbed against the underwear with the slight vibration generated.

Her eyes were rolling back due to the intensity of the movement, the tentacle was moving up and down instead of piercing back and forth, her upper body was rampaging trying to escape the pleasure. Then, the movement of the tentacles that were rubbing her chest became violent.

She felt that the stimulation coming from her breast was concentrated on her nipples, wrapping around her entire breast that a man's hand couldn't, it squeezed her nipple.

Milking livestock.

It was a movement resembling it.

As she was lying on her back in the air, her breasts, which were misshapen under its weight, were squeezed like a cannonball. The tip of it. The tentacle that was stimulating the nipples also moved back and forth like a snake coiling around so that it can stimulate the areola and nipple at the same time.

Her entire vagina and breasts. It could be said that both were the largest erogenous zones on a woman’s body, it would not leave the other while violating the other. Frederica shouted, ignoring the drool from her mouth, and her upper body and legs twitched over and over again. Her boots had slipped off at some point and her toes curled as though to grab at something.

The stain on her trousers gets bigger and bigger each time, and now it had spread to her buttocks, completely resembling that of a child who had made a mess.

Moreover, she was wearing thick trousers suitable for adventure. That was how much Frederica's love juice leaked.

"No, on't―― Mo, uuu... op iiit!"

Her face was looking up towards the ceiling, and tears spilled from her eyes. Her eyes were almost white, and her mouth was unable to catch up, and she was desperate to take in oxygen as she began to breathe wildly through both her nose and mouth. While exposing the shameful appearance of her nose swelling, dripping tears, and snot, however, the movement of the tentacles did not stop.

The tentacle continued to move up and down as it repeatedly inserted itself. It licked her womb, it stimulated the top and bottom part of her vagina, as well as the walls on both sides.

In this situation, she couldn't keep up.

The pleasure that exceeded the amount of information that Frederica's brain could process was ruthlessly sent to her.

It was both pleasurable and painful, and her rational mind and body went into a rage as though to scream. But her lower abdomen, her most sensitive weak point, was immobilized, and she could only let her body flail about.

Even though she knew it was pointless, it was the only way for Frederica to survive. It was the only way to protect Frederica's reason.

Like this, she was struck by the climax for the second time, her mind and body were exhausted to the point she couldn’t even react anymore, then finally, at the deepest part of her vaginal canal... The white liquid was ejected.

Her upper body, which had been unresponsive with her eyes rolled at the back, trembled once at the end.

As though to express its gratitude, her vagina, which had been repeatedly expanding and contracting like crazy, gently enveloped the mucus tentacle. Then the tentacle slipped out of her vagina, the cervix closes its entrance to keep the semen from escaping.

"Ahh―― Ahh, hii... Hii, ahii"

Frederica―― who certainly felt the heat in the deepest part of her womb and orgasmed. A heat different from those was building up inside her body. And at the same time, that heat was taken away from her.

Mana.

The source of power needed to use magic. It was being taken away from her. The power was being drained.

This sensation also became a pleasure that enveloped Frederica's entire body. Her brain was burned by the pleasure, and while she was running out of oxygen, she was still trying to carve this pleasure in the back of her brain.

She felt good. She felt good to have semen forcefully poured into her. And being robbed of her mana.

It had become a habit. Mana was taken away at the same time as the climax. She was deprived of her mana while it was pouring its semen. It seemed that she could not help but realize that she was a woman.

...And she understood that the Black Ooze would keep violating her until her mana was gone.

Kacha――. She heard a dry sound. Regaining consciousness at the sound, Frederica turned her tear-clouded, hollow eyes towards the sound from her lower body.

There, a new tentacle was unfastening the belt that held her trousers. Unlike the first time, there was no hesitation in its movements. The belt was easily pulled out, and the trousers, which were wet in the crotch area, were slid to her knees.

What was revealed was a pair of black underwear that was soaked with her love juices and the mucus of the black ooze and sticking to her pubic area.

The underwear, which was tightly attached to her pubic area, revealed her secret pubic area, and a slight bump on top of it could be seen.

Seeing that situation was making her feel embarrassed, she tried to adjust her unstable breathing.

――But before Frederica adjusted her breathing, the mucus tentacle lifted the crotch part of her underwear slightly and went straight to her vagina.

"...Ahh!"

A new stimulation was sent to her brain that was already burned by pleasure.

It was a little better than the previous stimulation. Her voice leaked out.

Frederica thought she had a sore throat. It was due to her yelling out loud at the inexplicable pleasure.

When she realized that, her body trembled from the shock of the sudden insertion.

She became unresponsive as though she were a puppet. No, Frederica had regained consciousness, but her body had not returned to normal.

The stimulation of the insertion, the sensation from her vagina being pierced. She understood that, but she felt as though there was a wall separating it.

The tentacle dexterously and gently moved Frederica away.

After lowering her down to the ground, it rolled her over onto her back. It was easy to perform sexual intercourse with her hips and ass sticking out. In that position, there she saw Fiana who was being caressed through her entire body with her eyes.

Frederica's face was reflected in her crimson eyes.

In the depth of the abandoned mine without a mirror, a lustful face was reflected in it.

For a few moments, Frederica didn't realize that it was her face. When was the last time she had looked in a mirror? Was it when she had rented an inn for the night in the village at the foot of the mountain or was it when she had cleaned herself up in the royal capital before embarking on her final journey?

What she saw there was a face she did not know.

The face was clouded with lust, a tongue was hanging down, the half-open lips were smeared with saliva, and the face was dirty with sweat and snot. It was not a woman's face. It was a face that people must not see.

――Even a prostitute would not look so miserable.

A face like that seemed to reflect in Fiana's eyes.

"Ahh―― Haah..."

The face roared. She was happy and relaxed. While smiling, she brought her face closer to the face that was devoid of emotions. Her lips loosened by the tentacle's caress, it was slightly opened, Frederica's action was not denied.

Both lips met.

The lips were soft and warm. The feeling was different from the mucus of the black ooze, and the sound seemed to be slightly louder.

Although Frederica prides herself on her sexually unrestrained nature, however, she only had sexual relationships with men. She didn't find homosexual sex detestable, but at the same time, she didn't find it interesting either.

It was supposed to be.

"Nn... Fuu"

It was soft and warm... At first, she just stack her lips. When she took a deep breath, it smelled sweet, which was different from the rotten odor of the tentacle.

Perhaps it was because it had overlapped with the rotten smell, the smell was even more fragrant and lovely.

When Frederica kissed her, the first to react was Fiana, who was in a hypnotic state.

Frederica had no idea what Fiana thought of her kiss, but she accepted it by sticking out her tongue. However, it was not for the purpose of entangling it with her tongue. She only stuck out her tongue to accept it because her lips were stimulated. There was no intention to caress her.

However, she still stroked Frederica's lips underneath and touches her white teeth.

Frederica felt a different feeling from her chest.

"Hahaha―― Somehow, it felt weird."

Even she didn't know. Frederica touched Fiana's tongue with her stretched-out tongue, as her back was pushed by unclear emotions.

That was all at first.

They opened their lips and let their tongues touched. It was not the kind of intense kissing that adult men and women do when in a relationship. It was just a touch, just to check the warmth. It was a child-like kiss.

"Uu―― Nn, fuaah"

"――Nn, uun"

When Frederica intentionally dripped her saliva, Fiana swallowed it without refusal. Even if the saliva was dripped through the tongue and sent into the mouth little by little, Fiana swallowed it without being disgusted. Gulp―. Frederica's chest became even hotter as Fiana swallowed the saliva.

She didn't have this kind of hobby.

But strangely enough, she didn't feel bad.

Their ample breasts rubbed against each other, and their wet clothes made dirty noises.

Before she knew it, Fredrica's body was rubbing against Fiana's, caressing her with her entire body, without her even realizing it. It was like the kind of body washing that nobles do.

She had two hands, and yet she used her entire body.

Frederica couldn't understand the intention and even thought it was in bad taste, but―― Oh, well. It wasn't bad, she thought, changing her mind.

Even though they were still dressed, rubbing against a woman's soft body felt different from being invaded by the tentacles of a monster. Warm, soft, and smells good.

When she licked off the rotten liquid that stained Fiana's beauty with her tongue, the indescribable taste that she had recently become accustomed to spreading over her tongue. At first, it made her feel nauseous, but now she could swallow it without any problem.

She twirled it around with her saliva and swallowed it.

She took her time cleaning the rotting liquid from Fiana's lips, cheeks, and neck.

This made it hard to tell which of them was doing the serving.

Still feeling strange, Frederica cleaned Fiana's beautiful face. She cleaned it, not with the rotting fluid, but with her own saliva, in order to stain it again. This contradictory act excited Frederica and thought she was indeed a pervert.

Being violated by a monster and she was violating a woman. She was unbearably excited.

"Haha―― Aaahh, haha"

She thought that something broke again.

And just because she thought it, she didn't want to stop this act though.

The beautiful elf with beautiful silver hair had been stained with black mucus, and now she was about to be violated by a woman. She was being violated by a monster and a woman.

She was unbearably excited about the situation.

She had just been violated to the point of her almost fainting, but that situation alone was enough to make her unnaturally excited.

Her breathing became erratic, and her body started to move a little more violently.

When she twisted her fleshy body around her equally fleshy body, they made a squishy sound as though they were coated with a special kind of liquid. She caressed Fiana's entire body, making sounds.

She rolled her own nipples on the white vestments, and moves her knees up and down, touching Fiana's crotch, which was protected by her underwear and robe.

She felt something different from the tentacle on her knees where Fiana's underwear was. She could feel a warm, raw texture.

And as Frederica had expected, there was a huge flood there, wet with a liquid that was not as sticky as the Black Ooze mucus.

Like Frederica, she had leaked so much of her love juice that it was staining her clothes.

Her mouth slackened at the thought, and she moved her face closer to Fiana's ear. The long ears that were unique characteristics of elves.

The other day, when Frederica stimulated her ears at the encampment, she remembered that she had a wistful expression on her face.

"You're just like me."

She murmured and took the ear to her mouth.

Then she felt a small but definite trembling in her hypnotized state. It was not that the tentacles intensified their caresses. Yes, the tentacles were still caressing Fiana's entire body, but they were somewhat gentler now that Frederica was on top of her.

It was the ears.

This elf has weak ears.

When she realized that, Frederica gladly bit it.

"――Ahh――"

A charming voice leaked from her lips.

While listening to her sweet voice, exhaling hot breath to the ears that she bit, and slowly but firmly crawl her tongue as though scraping the earwax. Using her tongue to poke over and over again. From the ear canal to the hole, and back to the ear canal again.

"Haah, ahh―― Fuu, ahh, aaahh"

"Hii... N-no..."

Fiana's body convulsed a little every time a tongue crawled on her ears. Her tightly gripped fist was trembling.

This female elf was feeling it. At the same time, she was trying to reject it. She was trying to deny it.

That was her reaction.

Frederica still crawled her tongue in her ear and guided a tentacle to the other ear. Perhaps sensing Frederica's intention, or perhaps learned that it might be an erogenous zone other than the vagina and breast? A tentacle as thick as the tip of a pinky finger entwined itself with the long ear, and then dug into the ear canal as well.

"Fuaahh!?"

Fiana trembled strongly.

Her eyes, which should have reflected nothing at all, flashed with surprise.

"Wh, at!? W-what are you!?"

The hypnosis was broken.

Did they give too much stimulation, or did Fiana recover her mana to the point where the spell could not hold? Either way―― it would have been the worst.

"N-no!? W-what!?"

She could not understand what was going on and struggled by swaying her bound body, but she could not do it. She could not understand where she was, what was being done to her, or what the situation was.

Without understanding anything, the ears that were reacting even in her hypnotic state were caressed.

The stimulation from her body and ears by the caresses of the black ooze was unbearable to her.

Frederica could never win by herself―― in a sense, when she saw Fiana, who could be said to be strong and superior, being confused and rampaged, she could not put it into words... but she felt happy.

It was like she was laying down the absolute knight that was making a moaning voice. Such an unrealistic sight. Excited about that, Frederica resumed her tongue crawl in Fiana's ears, making her chest throb. At the same time, it crawled and stimulated her entire body, the part that had the most attention, was attracting Frederica's hands―― it stimulated the big breasts that were disproportionate from Fiana's height.

Kneading as though scooping up from below, and picking up the erected nipples with her fingers so that it would be visible even from the top of her clothes.

"Ah !?"

That alone made Fiana's body twitch again.

Fredrica was an adult, but even so, her big breasts were too big to fit in her hands. No, her breasts would be too big even for a skilled man's hands. When she put pressure on her ten fingers, the breasts were so soft that her fingers sank through them, but when she relaxed her fingers, the breasts would return to their original shape. Even though her clothes and underwear were in the way, she could feel how soft they were, and she couldn't help but fantasize about how soft they would be if she took off her clothes and squeezed them directly.

Between her legs―― Fiana's leg was stuffed between her legs.

Looking at Fiana, She was still confused because she still could not understand the current situation.

It was a natural reaction. The legs―― the lower half of her body reacted to the caress from her ears and chest.

Seeing that, Frederica lifted her knees slightly and pressed them against Fiana's crotch.

"――Uaaahh... Aahh"

Was she lucky or unlucky? The knees seem to have stimulated not only the genital area but also the clitoris above it, and Fiana shook her hips as she let out a small cry.

Fiana's hips quivered as she let out a small squeal. Frederica was amused by her reaction, so she used her tongue to stimulate the ears, her hands to stimulate the breasts, and her knees to stimulate the pubic area.

"S-sto―― W-what... Stooop!?"

In her confusion, Fiana shouted. No, it was not confusion, but rather a voice of fear. She swayed her restrained body wildly and tried to escape.

However, she could not escape the restraint of the Black Ooze. Even if she was a trained knight, she was still only a woman. Moreover, Frederica was also restraining her.

In addition, the more she wildly swayed, the more it stimulate Frederica's desire to abuse her, as the caresses became more intense. She was not sure if Fiana was resisting or convulsing, but the stimulation continued, her breasts were being squeezed hard and a tongue was crawling into her ear.

Fiana was unaware that her lower body swelled in pleasure and pushed her crotch against Frederica's knees in an attempt to get more pleasure.

"Fufu―― You are just a woman after all."

But with a desperate intention, a warm tongue poked into her ear canal. At the same time, the tentacle of the Black Ooze also stimulated her other ear hole―― and the most sensitive part of the body, the vulva.

"Hii!? N-no――"

Fiana screamed at the sensation of "something" crawling up her legs through the stockings hanging from her garter belt, stimulating her calves and thighs.

Something was crawling up her lower body. Even though she was confused, she could still feel it.

The knight who once cornered the Black Ooze leaked a twitching scream.

Then, finally, those red eyes caught Frederica's. It reminded her of how beautiful she was, seeing the face of a female mage who was dazzled by lust earlier-――but now expressing a confident smile that she knew so well.

"F-frederi――"

The Black Ooze tentacle ruthlessly pushes its tip against Fiana's pubic area, as she was trying to say the name.

"W-what is it!? This, this!?"

Frederica looked down at the face of the "knight" who reacted like a woman, which was too unreliable to be called a knight. Frederica was not sure where her true feelings lie, as the face was a mixture of confusion and fear.

But it didn't look like she was feeling any pleasure.

It would be so.

She would be a pervert to take pleasure in a situation like this.

That was why Frederica's mouth loosened when she saw her past self overlapped with Fiana. Although only one ear was released from the stimulation, Fiana looked up at Frederica.

"Frederica-san..."

Feeling her gaze, Frederica put her mouth closer to Fiana's ear.

Fiana stiffened her body, being wary that she might resume licking her ears again.

"You were brought here to give birth to a monster together with me."

That was what Frederica said. At the same time, another tentacle lifted the robe hanging in the front that was hiding the underwear.

What appeared was a pair of thin, white underwear with gorgeous embroidery. The left and right sides were woven with strings, a shape that entice a man's lust just by seeing it. It was the kind of provocative underwear that a nobleman or a woman with a sexy body like Frederica would wear. Though, they were not suitable for adventuring and were probably a bit too expensive for a knight to wear.

The bottom of the underwear―― the crotch ――was already wet and could already see through it due to the caresses and stimulation of the tentacles.

The pubic hair was the same silver color as her hair, and unkempt, as though it had not been groomed during the trip.

The wind that she felt in her secret place told her the state of the lower half of her body, and she strengthened her rampaging. However, it was not possible to release the restraint just by being violent.

Frederica's black and Fiana's white underwear sway from side to side as though inviting a man. Underwear was wet with mucus and love juice sticking to their skins, and it was out in the open.

"Ahh――"

In contrast to the rampaging Fiana, Frederica let out a sweet voice, as though expecting it.

The underwear that was hiding her lower body, the crotch part, was pushed aside by the tentacles.

At the same time, Fiana's white underwear was also pushed aside. Thick pubic hair and flooded with love juices due to the caresses were revealed in her pubic area.

"Hii... W-what are you―― What are you doing!?"

Forcibly―― at the very least, Fiana turned her gaze to Frederica, thinking that she must act correctly in front of her. However, the person to who she turned her gaze was expressing an obscene face and squinting as though she didn't care about Fiana anymore.

To endure what was being done to her, the hand that was rubbing Fiana's chest touches the ground and supports her body. She was bewildered by the fact that she could not close her legs due to Fiana's leg being in between.

Even if she didn't, she was still restrained by the tentacles―― this was more likely to give her the illusion that she was the one violating this elven knight.

Even though it was supported by her inner garments, the rich breasts hanged down due to gravity and positioned themselves on Fiana's chest. Even though the breasts were covered by clothing, the four big breasts smeared with mucus were intertwined together... If a man were to see it, they would drool due to the amazing sight.

"You have a bad memory, don't you, Fiana-sama?"

She looked down at her, while her mouth was loosened up.

"You will give birth to a monster."

It was the moment when she said that. Frederica's vagina was pierced by the monster's tentacle. It was not that thick... It was a tentacle that was as thick as a typical adult man.

It pierced the depth of her vagina at once.

Even though she was violated earlier, she felt dizzy when it suddenly pierced deep, and her tongue stuck out as though she was gasping for air.

"Aahh―― Th-, uu. Th-... Aahh, aahh..."

Every time she was pierced by the tentacle, her breasts shake and rub against Fiana's chest. Frederica trembled with a different pleasure from the nipples rubbing against each other and being caressed by the tentacles.

As her body trembled as she was poked, her sweat was pulled by gravity and dripped onto Fiana. It hit her cheek and stained her face―― but she remained frozen, unable to understand what was happening in front of her. She looked up at Frederica's face, stunned.

For a moment, she forgot that she was restrained in a "大" figure and was still being caressed by the tentacles.

"Eh... eh?"

What came out of her mouth was not rejection or disgust, but a powerless voice of doubt.

No, it wasn't even doubt, she didn't understand the reality... A stupid voice.

"Mo... eh? Mo, monster..."

For Fiana, a woman named Frederica was an adventurer. She thought that something must have happened when she met this monster at the abandoned mine, but her confused mind couldn't remember the details――.

It was an existence that vanquish monsters and putting a stop to the evil-doers. And getting paid for it. That was an adventurer.

However, that adventurer was... being violated by a black mucus, delighted and letting out a gasping voice.

"Frederi―― eh? That's a monster..."

The adventurer was moaning and on top of her. She was on all fours and kept her body close together while her body was swaying and being pierced.

Fiana tried to avert her gaze away from Frederica while their soft body overlapped with each other and conveyed a different warmth than the tentacles that were restraining her hands and feet, making her feel comfortable.

"Aahh―― Naahh..."

A sweet voice reached her ears. One ear was still being caressed by a tentacle, so she heard the voice as a muffled sound, but her other ear heard the panting voice clearly. A sweet, hot, pant voice of a female adventurer named Frederica.

It was almost as though it was directed at her, and Fiana's white porcelain cheeks blushed shyly.

"Stop it, Frederica-san! This is――"

"G-good... unn, the, re... There!"

As though she couldn't hear Fiana's voice, Frederica moved her hips and led the tentacle to her weak spot.

It was treated roughly, but it was gentler than when she was forced to climax earlier. Roughly, then gently. The body was delighted with the treatment and gently squeezed the tentacle that was piercing her vagina under Frederica's will.

Fiana turned her head to the side to look away from Frederica, but she was still looking at her from the corner of her eye.

The look was one of interest and disgust. Doubtful, she tried to get a closer look at Frederica's expression, loosened by the pleasure of sex.

Frederica was a mage of great beauty. She had a well-organized appearance and a sharp gaze that expressed her strength. Fiana thought that ten out of ten men would probably all agree that she was beautiful. That Frederica exposed an obscene expression in public due to the pleasure given to her.

It was an unknown expression for Fiana, who had lived a long time and only had the experience of doing it in a human being.

That was why she looked.

Even though she was disgusted, she showed an interest.

(...Disgusting)

Looking at Frederica, Fiana thought.

Disgusting.

Weird.

Because――. When she turned her gaze to the side, she could see a mass of mucus that was restraining her. This was the thing that was violating Frederica. She move her fingers, not her restrained arms, to check their texture. Through the white glove, she felt a sticky texture. It felt as though she had grabbed something rotten and liquidy.

The feeling made her feel sick.

Being violated by such an unpleasant thing―― the woman in front of her was moaning.

She felt uncomfortable. It was normal to feel revulsion when it was disgusting.

Even so―― Frederica was moaning while looking down at Fiana with such a disgusting expression. She felt good. She shook her hips as the tentacle moved, and each time the black mucus rubbed her clothes, it made a disgusting sound.

"-ummin, uu"

Frederica, who was trying to hold in the pleasure as long as she could due to her climax coming near. She tried to mutter some words, but every time her vagina was thrust up, her words turn to a moaning voice.

Her long blonde hair danced in the darkness of the abandoned mine, bouncing in the sunlight that shone through the ceiling and covered Fiana's entire field of vision. Her jade-colored eyes moistened with tears as it looked at Fiana's crimson-colored eyes. Fiana, while her mouth was opened, looked up at Frederica in a daze.

"Y, ou―― too, will become... like this"

Surprised. She felt her body tremble.

Fiana closed her mouth as Frederica's words brought her back to reality.

It was a face contorted with fear. A face twisted with fear.

A face a knight shouldn't show... it was the face of a woman who understood what was going to be done to her.

Fiana's face would be made to look like that, a face that was distorted, nasty, and obscene. It was easy to understand what was going through her heart.

"Th... be, uu, um... cu... ahh"

Then, Frederica who was looking down―― her shoulder quivered, slowly losing her strength. No, Fiana couldn't see it, but she was still moving her hips.

Fiana knew from that expression that she had climaxed. She knew about it due to her past experience. But...

"Fuaahh!? Aauuh―― Ahh, ahh, ahh"

Immediately, Frederica's voice grew louder. The shackles had come off due to climaxing and even the desire to endure it disappeared.

It was shameful than before... It was exposed for Fiana to see, the face that was embarrassing to show to a relative or a companion, let alone the same sex. Her eyes were about to roll back, exposing their white color, her mouth wide open, gasping voice, saliva dripping, and her nostrils were swelling due to breathing violently.

Her strong beauty was gone, and instead, a face that was too disgusting to be called a woman's face.

Fiana gasped at her distorted face.

She remembered the words Frederica had said earlier.

That she would be like that too.

She had been told that.

A chill run down her spine. As she finally remembered, she made her body rampage trying to escape from the mucus that was restraining both her hands and feet. However, even with how much training a knight did but by restraining not only the wrists and ankles but also the elbow and joints, there was no way for Fiana to escape.

Then she thought of doing something with it using magic, but she was restrained, and if there was a human in front of her, she and Frederica would get involved if she fired her magic. That was Fiana's kindness.

If she didn't think of Frederica, she might be able to escape. Hurting herself and Frederica... then, she could perhaps escape from the monsters.

Next, she looked around as far as she could twist her neck to see if there was something she could use to escape.

She remembered exploring the abandoned mine with her fellow knights. She looked around to see if there were any other prisoners and found a person.

His face was down and his long purple hair was hiding his expression, but his clothes were familiar to him.

"A-alfira―― Alfira!!"

Desperately calling out the name of a female knight who was motionless and looking down. She tried to reach out, but she was too far away to reach.

Alfira was still the same as when she was violated until she fainted earlier, her hands hung from the ceiling bound together, and her legs spread wide open. She hadn't woken up since then and was trying to recover her strength by sleeping. She was so deeply unconscious that she didn't even respond to Fiana's voice, it showed that she had been drained of her strength.

However, Fiana, who was in a panic and didn't pay attention to her appearance, called Alfira's name over and over again in a loud voice. It was so loud that it drowned out Frederica's gasping voice. Frederica puts her lips near the ears of that loud elf female knight.

"L-like I said... right? Knight-sama..."

Her words were choppy while moaning, but Frederica desperately tried to convey the words to Fiana. When the tentacles started to move more violently to dismiss her efforts, Frederica's whole body started convulsing again. How many times did she climax?

With pleasure and fading consciousness, it was difficult to even count. Her arms that were supporting her while on all fours lost strength and fall on Fiana's body.

Her two rich breasts were crushed and the nipples rubbed over her clothes.

A tentacle crawled between her breasts then moved through their clothes and insert itself between Frederica and Fiana's breasts.

"Hii!?"

Fiana saw the tentacle up close, she screamed and twitched a little.

It was not only its appearance but above all the smell was so bad. She glanced at the sticky mucus and smelled the offensive odor of some kind of liquid, then a moment later, Frederica swallowed the tentacle.

"S-stop, Frederica-san!?"

"Nn―― ahnn, fuu... nn"

After swallowing it, she released it from her mouth, then crawled her tongue through it. Her tongue peeking through her wide-opened mouth was stretching, trying hard to lick the entire tentacle, which was about the same size as an adult male penis. She moved up and down, then twined her tongue around the tentacle with the tip of her tongue, giving a strong stimulation to the tentacle, then swallowed it again.

Sucking on it, her nose emitted the same foul smell as the tentacle.

Each time Frederica inhaled the smell to her heart's content, she felt an almost fainting sensation of pleasure. With just that, she climaxed a little and almost fainted.

Her lungs were filled with a strange odor, and tears overflowed endlessly as the smell passed through her nose.

She felt pain and unpleasant... but she felt good. At this great pleasure, Frederica's mind was at its mercy, but her body was still trying to serve it. Her body remembered that it was making her more comfortable.

Rather than seeing Frederica, who worked hard, desperately, almost fainting-with a half-blinded face and a look that could only be taken as coerced, rather than seeing something incredible. Fiana looked like she saw something horrifying.

Desperately, almost fainting― with half-dropped eyelids and an expression that could only be taken as demanding, Fiana looked at Frederica as though she were looking at something horrible, rather than something incredible.

Frederica got more excited as she was servicing the tentacle while someone was looking at her like that.

Her nose started to breathe hard, and she desperately working on the tentacle.

Then, Fiana could see a white liquid ascending through the black translucent tentacles. Forgetting to resist with her body, She was watching Frederica's blowjob... She was staring at her as though looking at something horrifying.

When the white liquid reached the tip, the tentacle that Frederica's mouth was servicing, it had pulled out.

What overflowed from the tip was a strange odor different from the rotten smell of the black mucus tentacle. It splashed to Frederica and Fiana's faces.

"No!?"

She screamed and squinted her eyelids to prevent the liquid from entering her eyes. The amount of white liquid stained her forehead, the bridge of her nose, her cheeks, her lips, and even her throat. She was surprised by the amount of liquid, but she couldn't hold her breath forever, however, due to her holding her breath long enough to suffocate a little, as she breathe in suddenly, she smelled the strange odor up to her lungs.

"T-this is..."

Fiana was familiar with the smell. She had experience having sex with her past lovers and also had already done some oral service that sometimes used her rich breasts―― she was a bit reluctant though. One of her lovers in the past liked that kind of service.

So she remembered it.

Semen.

A source of life released by a man.

It was released from the tentacle of a monster.

"Wha..."

Stunned, Fiana muttered as the smell wrapped her face. Why? How――?.

In this world, the reality was that the biology of monsters had not been investigated that well. Monster, an enemy that had to be defeated, and if their habitat were known, it would be normal to plan and surprise them, not only to destroy the nest but to kill the monsters.

They must be killed. That was the foundation of monster subjugation, and not to research them.

However, monsters were created by the demon king, not by giving birth to children or having sexual intercourse. Remembering this, Fiana was confused.

Thinking about it... She was awake and didn't care about it until now, but... why was this monster violating Frederica? And why did it release semen from the tentacle?

As she thought that―― From the bottom of her heart, She rampaged strongly.

A petite body was pushing up her hips to push away Frederica, who was on top of her, and tried to tear off the tentacles that were restraining both her hands and feet. She used her mana that had recovered a little to strengthen her body, the tentacles that were restrained her arms stretched a little... but that was all she could do.

The soft tentacles were quite strong and could not be torn off at the slightly stronger force.

"No, no... no, no, nooooo!!"

Would be violated.

Would be moaning.

Even though it was illogical―― She completely lost herself when she saw the tentacle release semen.

It was semen.

The source of life.

A precious thing that became life when released into the vagina―― into the womb. Mercy and affection for the child. It should be a noble act. It should be. It was supposed to be. Fiana, who prayed to the goddess daily, had a stronger belief than Frederica.

However.

But.

But still...

"Stop―― Stop!? Release me... Let go of me, Frederica!!"

Saying it in a strong tone while rampaging strongly.

Because. It was because――.

"It's from a monster, you know!? Monster... A monster's child is―― Hii!?"

Suddenly, she felt an unpleasant sensation in her lower body. Perhaps because she had imagined herself being violated, her body became more sensitive. The tentacle climbed up to her knee stockings hanging from the garter belt and let out a twitching scream at the sensation of a tentacle crawling on her bare skin between her underwear and stockings.

There was no trace of the elven knight who had strong magic and nearly defeated the Black Ooze. It was a face of a woman who was afraid that she would be violated, a woman who could only shake her head in disgust like a child.

Frederica, who was pierced violently by a tentacle and could only leak out a moaning voice, loosened her mouth.

"G-goog―― Heels ghood, itsh fwine..."

"No! not that!?... Something like this is―― Alfira!? Alfira!!"

Fiana was trying hard to resist, asking for help from a knight who was lower rank than herself.

Another shadow was reflected in her field of view.

It was a familiar small shadow.

It was Satia.

She, like Fiana, was restrained in a bed of flesh and shook her body.

She had little flesh, in other words, tight, she have no wasted extravagant flesh. Horrifying tentacles were crawling around her beautiful doll-like body.

"Satia-san!"

Fiana called out her name in a tearful voice. Then, the face that was nearing to reach her climax turned to Fiana.

Looking at that face, Fiana's eyes widened in disbelief... Despair came to her mind.

Satia was also moaning like Frederica. While holding a tentacle in her mouth and lovingly crawling her tongue around it, her whole body was caressed and a tentacle was in her vagina.

Slowly, with the gentleness that did not intend to break her body, it was violating the slave girl back and forth.

"Hii―― N-no, Satia-san!?"

Satia smiled towards Fiana as she called out her name once more. She also had the same expression as Frederica's. The same face as when Frederica told Fiana that she would be the same as her. Fiana screamed, as though Satia had told her that she would soon become like Frederica

A tentacle touched Fiana's cheeks. The rotten odor passed through her nose, it gave off a strange odor that could even hurt her brain.

"Stop, stop it... Don't――!?"

She shook her head from side to side trying to escape from the tentacle while spitting words of resistance from her mouth, then suddenly a new tentacle emerged from the other side and Frederica shoved it inside Fiana's mouth as to close it.
