I’ve Been Reincarnated as a Tentacle Slime~ I Want to Live a Comfortable, Secure Life and Do Whatever I Want~ - Chapter 18

As the light brightened, I woke up, but Rio was still sound asleep. I wove several tentacles in a mesh pattern, laid Rio down, and got out of bed.

“Hah! Hah! Hah!”

I begin practicing with the iron sword I took from the bandit. Thanks to my [Slash] skill, I look fairly skilled to an untrained eye. To defeat the bandits, I’ll likely need to move in human form and gather information in the village.

After practicing for a while, I sensed Rio was about to wake up, so I returned to my slime form.

“Good morning, Master.”

Rio greets me while rubbing her eyes sleepily.

“Yeah, good morning. Are you feeling better?”

“Yes. I feel more energetic than ever.”

That’s true. Not only was she nourished, but I also pumped slime into every corner of her body, even inside, consuming the waste. Her complexion improved, her skin tightened, and her once gaunt body became soft and feminine. Her hair was silky with fox ears, and her tail was fluffy, making you want to cuddle it. I didn’t expect her to turn into such a beautiful girl. What a hidden gem.

“I’m going hunting for a few hours, so stay here quietly until I return. Monsters don’t approach near the black gate. It’s written on the sign over there, and I’ve experienced the safety myself.”

“I understand. Be careful.”

“Ah, I almost forgot. Your clothes are all torn, so wear this on top. If you don’t like it, you don’t have to.”

After getting up, I threw Rio a lightweight coat made from wolf and rabbit pelts that I had made casually.

“Thank you so much! I’ll treasure it!”

Rio embraced the coat and waved me off. Well, if she’s happy, I guess it’s not so bad.

◆◆◆◆◆◆◆

I returned to Rio after slaying about 400 monsters in the Monster Houses from the 3rd to 7th floor. The room was filled with a distinctly feminine scent. Rio sat hugging her knees, legs slightly apart, playing with her anus and n1pples that had been developed yesterday, while masturbating.

“Mmm… ngh… ahh… aah… nnh… huh? — Kyaa!?”

When Ria noticed me, her face turned beet red and she quickly apologized.

“I-I’m so sorry, Master… while you were working, I… um…”

“What were you doing?”

“I was getting pleasure from my br3asts and ass…”

Ria, looking like she was about to cry, confessed her lewd behavior.

“I’m not angry. In fact, becoming lewd is a good thing. You’re going to give birth many times from now on. Of course, it’s better to feel good than to feel pain or suffering.”

I patted Ria’s head with a tentacle.

“Now then, today we’ll work on developing your pvssy and womb, along with your ovaries. If all goes well, you’ll begin to conceiving by tomorrow.”

“I will finally be able carry your child, Master. But what does ‘begin to conceive’ mean?”

Rio tilted her head, confused by a word she had never heard before.

“This is your first pregnancy of the year. You understand that it won’t be over after one or two, or even ten or twenty times, right?”

“Y-yes, Master!”

“To get back on track, the goal this time is to defeat the bandits, and I want to have you give birth to as many as possible in one go, ideally four. Therefore, it’s necessary to expand your pvssy and womb.”

“Will my pvssy and womb become loose?”

Looking sad, Rio asked me. Her fox ears flopped down, looking absolutely adorable.

“No, when you’re not pregnant, I’ll make sure it stays like this, so it won’t get loose. After all, it’d be a problem if slime were to drip from your womb while you’re pregnant.”

“That’s a relief. I was a little scared because I’d get pregnant a lot.”

Rio sighed in relief and stroked her fur down. Her fox ears stood up straight, making it easy to read her emotions.

“Now, regarding the ovaries, the slime applies semen to the female’s eggs, and the sperm fertilizes the egg, turning it into a slime core. In a normal body, only one egg is produced per month, and any cells that almost become eggs die. This leads to only one ovum being released, which means only one slime can be produced per month.”

“That would be troublesome, so I’ll develop (modify) Rio’s ovaries, injecting nutrients to prevent the eggs from dying, and keep them in a state where they can ovulate multiple times. The nutrient injection will be similar to how I directly injected it into your intestines yesterday.”

“??? What do you mean by an egg?”

There are a lot of question marks above Rio’s head. She hasn’t had that kind of education… what should I do…

“Should I say it’s an egg for having children? Normally, you need to try making children multiple times to have one, but here, the goal is to make it so you can get pregnant with many at once.”

“I understand! Master is going to help me create many female eggs, right!”

Rio’s face lights up with a bright expression, as if she’s saying, ‘I understand!’

“But if I give birth to a lot, won’t I have trouble getting pregnant again right away?”

She made a troubled face, and her fox ears drooped.

“It’s fine. At your age, Rio, you have around 400,000 female eggs. Even if you give birth to one each day, it would take over 1,000 years, so don’t worry about it.”

“I’m so happy! Master will be able to impregnate me a lot!”

Rio’s face lit up with joy, and her fox ears and tail stood up excitedly.

“Well then, undress and come to me.”

“Yes, I understand…”

Embarrassed, Rio took off her clothes and stood in front of me, her hands covering her chest and pvssy.

◆◆◆◆◆◆◆

I stretched out my tentacles and coiled them around Rio’s hands, feet, and waist. I lifted her body and forced her to raise the hands that were covering her pvssy and br3asts, while making her spread her legs in an M shape.

“It’s embarrassing…”

With her face bright red, she tries to turn away, but the tentacles pull her gaze back toward me, forcing her to show me Rio’s predicament.

“Master, you’re so mean… Please forgive me…”

With her ears turning crimson, Rio begs for forgiveness, but I have no plans to accept it.

“Rio, your pvssy is beautiful.”

The tentacle soaked in aphrodisiac gently traces the slit on Rio’s pubic mound over and over.

“Ahh… huff… it’s so ticklish, mm… this feels strange…”

Rio lets out a soft moan and tries to twist her body, which is held down by the tentacles.

“That’s what you call feeling good. It’s the same as when you were playing with your n1pples or ass, right?”

“Ah… my butt, nn… haa… it’s so ticklish… oh… it’s so much more…”

“Does your anus, which has just started to develop, feel better than your undeveloped pvssy? I’ll make this feel just as good, no, even better.”

When the two tentacles part the crease of the pubic mound, a beautiful pink-colored pvssy emerges. The two tentacles fixed the labia majora open as if it were a specimen, then using new tentacles, covered the pink lewd flesh. The tentacles turned into slime, soaking into the labia majora and cl!toris, vaginal opening and urethral opening. Then, they released aphrodisiac and development fluid and vibrated like a vibrator with [Sonic Manipulation.]

“Hmmmm♡ Mmm♡ It feels so good♡♡ My pvssy is tingling, aaah♡ It’s going numb♡♡”

The mucus spread throughout her pvssy, everything vibrated with a buzzing sound, causing a pleasure that could not be experienced with a rotor or vibrator, overwhelming Rio.

–

Without inserting a tentacle into her v4g1na, I thoroughly and obsessively attack her pvssy for several minutes. Her vaginal opening opens wide, as if wanting something inside her v4g1na, inviting the male with its twitching motions. Her pvssy becomes all slippery, and love juice slowly seeps out, only to be absorbed by the tentacles, which then deliver an aphrodisiac in return.

“I want it so badly♡♡ Ahh♡ My pvssy wants the tentacle p3nis… Ahh♡ It wants it… Hyaa♡♡ Just like my butt, I want it filled up… Yah♡ I want it twisted inside me♡♡♡♡”

“What a troublesome girl. The naughty Rio needs more stimulation.”

“Rio is such a naughty girl♡♡♡♡ I want Master to tease me a lot♡♡”

I carefully insert a thin tentacle into her v4g1na to avoid damaging her hymen. Her cervix is tightly closed, and it seems impossible to enter. It looks like I need to first expand her v4g1na, before I can make her cervix open up. The tentacle inside her v4g1na expands, filling the inside of her v4g1na and enveloping the hymen. Just like with her pvssy, I release aphrodisiac and development fluid, remodeling it into a more flexible membrane so that the hymen won’t break even if I stretch the v4g1na wide.

Since it’s a special occasion, should I turn into a human and penetrate her, or penetrate the fully stretched hymen with an extra-thick tentacle after expanding it, or maybe impregnate her and have her break her hymen during childbirth— I’ll just penetrate Rio in normal human form. I need to reveal this before I go to the village after all.

In order to develop the inside of her v4g1na, the tentacle inside vibrate like a vibrator.

“Ahh♡ My pvssy is vibrating♡♡ Ahh♡ Ahh♡ Ahh♡ Ahh♡ It feels so good♡♡♡”

The development of the pvssy has just begun, as the tentacle forms spherical protrusions, starting to rotate. The area with the G-spot is slightly larger, and with the rotation, the sphere presses against the G-spot repeatedly.

“Hyaa♡♡♡ It feels so strange♡♡ My pvssy is so hot♡♡♡ Master is filling my pvssy with ♡squelch♡ ♡squish♡ sounds♡ I’m so happy♡♡”

While developing the inside of her pvssy, I peel back the skin from her cl!toris and wrap a thin tentacle around her cl!t, vibrating it directly.

“Hiiiii♡♡♡♡♡ It just snapped!♡♡♡♡ That feeling exploded with a snap!♡♡♡♡♡”

With a clitoral orgasm, Rio’s hips jolted♡ Her v4g1na that is engulfing the tentacle tightens, and the tentacle increases in volume to avoid being crushed. As the inside of her v4g1na relaxes, the tentacle starts to push open Rio’s v4g1na. Then, it presses the sphere against the G-spot, rubbing it firmly.

“Aaaaaaaaaaaa♡♡♡♡♡♡♡ I’m cumming♡♡♡ My pvssy is getting all wet♡♡ I’m cumming inside of my v4g1na♡♡♡♡♡♡”

Her v4g1na that was stretched wide contracts again, squeezing my tentacle. Then, to perform the next expansion, I increase the density of the tentacle. And as her v4g1na relaxes, the tentacle pushes open the inside of her v4g1na. This time, the vibration of her cl!toris and the G-spot are pressed hard, making the tentacle’s vibration stronger.

“Ohhhhhhh♡♡♡♡♡♡ I’m cumming♡ I’m cumming again♡ Even though I’ve already cum♡♡ –♡♡ I’m cumming again♡♡♡♡”

Rio’s pvssy continued to cum, and with each contraction and relaxation, the tentacles grew thicker, until Rio’s pvssy was stretched tight and impaled by the tentacles. The repeated contractions awakened her cervix ―――― her portio as an erogenous zone.

–

Thirty minutes had passed since Rio began climaxing, and finally, clitoral orgasm, G-spot orgasm, and portio orgasm aligned, causing Rio’s body to convulse violently.

“Ohhhhhh♡♡♡ I came♡♡ I’m already cumming♡♡♡♡ I’ve had a portio orgasm♡♡♡ I’m already ahhhh…ahhhh♡ahhh♡♡♡♡ I’m cumming again♡♡♡ —Ahhh♡♡ Wait…No♡No♡No♡No♡♡♡ I’m already cumming♡♡♡♡ —!!”

Rio squirts a huge amount of juice, drenching me completely. For a while now, Rio’s body was convulsing uncontrollably, unable to stop squirming from the endless orgasms. As I kept pounding her cervix with my tentacles, her cervix finally opened its mouth in sync with her orgasm.

I twisted my thin tentacle into her cervix, advancing toward her womb. To make the narrow cervix open, I struck her cervix repeatedly with my tentacles, training it. Finally, I reached the inside of her womb. To conquer her womb, I continuously sent slime into it, and in response, my tentacles grew thicker and larger.

–

The cervix that had its opening forcibly opened trembled and could only submit to the relentless tentacles that were invading it. Desperately wanting it to end and for the invader to leave, her womb served the tentacles with all it had. Pleased by this, the tentacles released slime everywhere, marking this place as mine. Her womb desperately swallowed the aphrodisiac and developmental liquid being spilled, enduring the tentacle’s assault, as if saying it’s okay to stay, just asking for gentleness. Realizing that her womb would accept more, more tentacles twisted further into cervix, and the tentacles that stayed there began to grow thicker. “It’s okay for me to stay, right?” the tentacles seemed to say, pressing against her womb.

Her womb kept accepting more and more tentacles, expanding widely, crying out, “Stop! I’m going to break!” but due to the development fluid, the elasticity of the womb increased greatly, and it expanded without breaking. Mistaking this development for tenderness, her womb started to serve the tentacles, who wriggles around inside the uterus as if they own it and spit out mucus for it to drink.

The tentacles, pleased that womb had started absorbing the slime on its own, began to expel a thicker, stickier white liquid, saying, “I’ll make you drink something even thicker.” Obedient, her womb began to swallow the sticky white liquid, doing as the tentacles willed. Unaware that they were being transformed into a sexual organ…

–

With the development of her womb complete, the tentacle moves toward its ultimate destination, the ovaries. The fallopian tube, which had felt the womb’s development firsthand, shudders as it waits for the tentacle to pass through. The tentacle, knowing that the fallopian tube is frightened, forcefully makes it swallow thick mucus. The other fallopian tube similarly accepts the tentacle’s assault and becomes aroused. The tentacle writhes inside the fallopian tube, not letting it escape until all the mucus filling it is swallowed.

Even if it continues drinking mucus without rest, the tentacles mercilessly spit out the next batch. If it can’t finish it, they force it in, and a new tentacle enters her fallopian tubes. The fallopian tubes stretch painfully as they surpass their capacity, helplessly changing shape in response to the overwhelming invader. Forced to drink mucus and injected, the fallopian tubes had completely given up resisting. Upon realizing the fall of the fallopian tubes, the tentacles attacked one after another. The once innocent fallopian tubes were widely stretched and gradually transformed into lustful entities, crying out as they succumbed to the lustful transformation.

Passing through the pitiful fallopian tubes, numerous tentacles made their way to the two ovaries. By the time they arrived here, the tentacles had learned that this female would endlessly continue to accept anything without limit as long as they pushed further.

Surrounded by tentacles, the eggs inside the ovaries could only wish they would leave. However, the tentacles thinned out and relentlessly entered the ovaries, into the girl’s sanctuary. The eggs trembled in fear, but it seemed that the tentacles’ target was the ovaries, which brought them a sense of relief.

However, things were not so simple. The ovaries were continuously injected with aphrodisiacs, development fluids, and nutrient-rich mucus from the tentacles, causing them to swell greatly. The ovaries, manipulated by the tentacles, expanded from a small house into something more like a palace, no longer resembling typical reproductive organs. Inside, they were filled with enough nutrients to nurture numerous eggs, and under the threat of tentacles and mucus, they immediately began ovulating, transforming into a meat toilet manufacturing plant. It was at this moment that the fate of the eggs, who once believed themselves to be safe, was sealed—they would become meat toilets.

–

“This should be enough for now. With this, it seems like it she would conceive four at once now.”

I developed Rio’s pvssy and womb, opening up the ovaries and removing my tentacle. As mucus poured out in torrents, what had once been tightly closed before the development, the single slit pvssy was now so expanded it seemed like a hand could fit inside, and looking inside, I could see the stretched hymen and, deep inside, her womb. The cervix was also wide open, with the inside of the womb being visible.

However, this is temporary, and over time, it will return to the way it was before, back to a single slit pvssy as it was. That’s how it was developed. Perhaps a bit too much was done with the ovaries, as Rio’s stomach swelled slightly, becoming large and swollen to the point where the location and shape were easily identifiable.

The person in question, Rio, had fainted from orgasming to much. Nevertheless, her body continued to convulse and she seemed to be continuing to orgasm even though she was unconscious.

“I haven’t cum yet, so I’ll use your assh0le. Plus, you can get some nutrients at the same time.”

I inserted the tentacle that gave the sensation of a p3nis into her anus, using a combination of vibration, rotation, and bumps to dig through her intestines. With the tentacles coiled around her limbs, I moved her up and down like a living onahole, thrusting the tentacle that penetrated her ass in and out with a squelching sound.

Twitch♡ Twitch♡ The twitching of Rio’s intestines provides an irregular stimulation, and I can’t help but release my semen into them. The semen that is concentrated with nutrients, aphrodisiacs, and development fluid sticks to her intestinal walls just like yesterday, and today, the intestines are filled with my semen.
