I’ve Been Reincarnated as a Tentacle Slime~ I Want to Live a Comfortable, Secure Life and Do Whatever I Want~ - Chapter 19

The next day, I spent the morning hunting in the Monster House just like I had the day before. By the way, when I got back, Rio wasn’t masturbating.

“Rio, today is the day you get pregnant. You’re prepared for it, right?”

“Of course! I’ve been ready ever since I decided to follow you, Master!”

I gently stroked Rio’s enthusiastic head with a tentacle.

“Just for the first time, I’ll impregnate you in my human form.”

The tentacle stroking her head turned into a hand, and the slime body transformed into a human body.

Rio was surprised, but not to the point of shock. It was as if she had somewhat expected it.

“As I thought, Master, you weren’t an ordinary slime after all.”

“You knew?”

“I didn’t know. But your way of thinking and behavior were like a human’s.”

True, I hadn’t really behaved like a monster… not that I even know how monsters are supposed to behave.

“I see. Then this form is fine, right?”

“Yes, Master.”

I embraced Rio and pushed her down.

◆◆◆◆◆◆◆

I stripped Rio naked and leaned over her in the missionary position. Aroused, I rubbed my more-than-20cm-long p3nis against her stomach.

In order to ejaculate directly inside her womb, it might not reach deep enough unless it’s long enough. — I covered it up with this excuse.

“Rio, I’m going to put it in.”

Without any foreplay, I pressed the mucus coated p3nis into the opening of Rio’s v4g1na.

The inside of Rio’s v4g1na was thick and meaty, it clung tightly to my p3nis, making it impossible to go deeper without forcing it apart. The sensual flesh also provided various pleasures, with bumps, roughness, and grains that felt so good I would’ve climaxed immediately if I let my guard down.

“Haah! This feels so good, Rio.”

“Haah… Mmm, me too… Ahh… It feels amazing, Master.”

As I pushed my p3nis forward, the inside of her v4g1na squirmed and provided service to my p3nis. I was fortunate not to cum before reaching her hymen.

“Is this the hymen? It’s hard to pierce because it stretches…”

“Master’s p3nis… nnf… is pressing against my hymen, nn… it feels so good.”

“I’m going to make it a bit stronger. I’ll take Rio’s virginity.”

I pull my hips back a little and thrust forward with power, pushing my p3nis in. Her hymen stretches, but it can’t hold up to the force and is finally penetrated.

“Aaaahhh…♡♡♡♡ I can’t! My hymen is going to make me climax…♡♡♡ I’m cumming!――――――――Ahhh♡♡♡♡♡♡”

Rio, feeling her hymen be broken, came just from that. The inside of her v4g1na contracted tightly, squeezing my p3nis, wrapping around, and the little bumps traced the ridge of my p3nis.

“Ah! Wait, no!”

The intense pleasure sparked in my head, and I ejaculated—no, I was forced to. Semen filled her v4g1na, and the semen that couldn’t fit spilled out from her vaginal opening.

This is unbelievable… Not only did I not get three strokes in, but I came before I even reached her depths, I never thought a developed v4g1na would bring such intense pleasure.

“Haa♡♡♡ My belly feels warm♡ Am I pregnant with my master’s child?”

“No… It’s more reliable if I ejaculate directly inside your womb. Shall I continue?”

Since it was originally a tentacle, its hardness doesn’t fade, and after regaining my composure, my p3nis advances into Rio’s v4g1na. It reaches her cervix, knocking gently with its glans against her womb.

“Ah♡ Ah♡ Ahh♡♡ Your p3nis is knocking, saying it wants to go inside my womb♡♡♡ I’m opening it now♡♡”

At that moment, the cervix opened with a gupaa♡, started swallowing my p3nis from deep inside, into the womb. The womb-pvssy was ridged and bumpy, the p3nis forced its way deeper while widening the passage. It wasn’t as developed as the v4g1na, so it had a little more room.

“Aah♡ Your p3nis is entering the baby’s room, fuaa♡ It’s coming in♡ My womb is thumping♡ thumping♡ like it knows something incredible is about to happen♡♡♡”

My p3nis pierces through the cervix and stabs into the wall of the uterus. But this isn’t the deepest point — her womb stretches out with a squish. The p3nis pushes further and further, until bokooh! her lower abdomen swells into the shape of my p3nis.

“Aahgaa♡♡ The baby’s room is… ahh♡♡ being turned into a toy by your p3nis♡♡♡”

I pull my p3nis back to her vaginal opening, endure the urge to climax from the pleasure of her obscene flesh, and with a squelch sound, thrust into the deepest part of her womb, until her lower belly bulges.

“Ahh! I’m about to ejaculate again!”

I can’t hold back and ejaculate, but knowing I can’t resist, I pull back to her vaginal opening while ejaculating. Then, I thrust again into the deepest part of her womb, ejaculating. Pull, thrust, ejaculate, pull, thrust, ejaculate, repeating endlessly as I ravage her v4g1na, cervix, womb.

Every thrust makes Rio climax, crying out as she squirts a gush of fluid.

“Aah♡ Aah♡♡ Oooh♡♡ I’m cumming again――――――――! Haah♡ Haah♡ Haah――――Nn♡♡♡”

“It’s time! I’m going to impregnate you!!”

I press over Rio, firmly pinning her body down so there’s no way to escape the act. This is what they call a mating press. Her two small legs sprouting from my side dangle, swaying gently.

“I’m starting to get pregnant――――Haa♡♡♡ The baby’s room――Nn♡♡ will become master’s sperm bag♡ It’ll become a slime farm――Yiiie♡♡ It’s happening♡♡♡♡♡”

I expel my semen while thrusting with force, penetrating her pvssy with my p3nis. Her lower abdomen swells up as if it’s going to burst, as my p3nis relentlessly slams into her small body without any restraint.

“Ahh♡ Ahh♡♡ Ahh, ohh♡♡♡ …………”

Rio opened her mouth and stuck out her tongue, drooling from the corners, her face a mess of tears and mucus, her lower abdomen releasing both fluid and urine, as semen spilled from the opening of her v4g1na, while various liquids poured from every hole as she fainted.

Even after fainting, Rio continued to be forced into pleasure, her body trembling with spasms, but because she was firmly pinned down by the mating press, the spasms were sent through her body, with her womb boring the full shock of the convulsions. The only part not secured, her legs, were shaking violently.

“――――I’m cumming!”

I thrust with the hardest push of the day into her lower abdomen, tightly grabbing her enlarged ovaries, and ejaculated.

“Gahyuu―――♡♡♡♡”

The ovaries, receiving the command for ovulation, released two eggs each. Rio experienced four ovulation orgasms, foaming at the mouth.

–

The four ovulated meat toilet eggs were taken into the fallopian tubes and filled with semen. Immediately after, the meat toilet eggs were surrounded by sperm and subjected to abuse, with genetic information expelled inside. In the blink of an eye, they became fertilized eggs, but the meat toilet fertilized eggs had no time to rest.

Dozens and hundreds of sperm break the shell of the fertilized egg and invade its interior. Then, the sperm expel more genetic information one after another into the meat toilet. The fertilized egg, the meat toilet, has no choice but to accept it, trembling and gradually enlarging.

Not satisfied with just that, the sperm demand more from the meat toilet fertilized egg. The egg can only submit to the demand, offering up its swollen form.

Hundreds and thousands of sperm swarm the swollen meat toilet fertilized egg, penetrating its defenseless body after its shell has been broken. Disregarding any risk of genetic defects, the meat toilet fertilized egg, overwhelmed by the selfishly discharged genetic information, tries its best to accept their desire.

The other meat toilet eggs also received the same treatment and continued to swell rapidly.

Even so, the demands of the sperm show no sign of stopping. Of course not—they didn’t come just to leave it as a mere fertilized egg. They’re here to transform it into a slime core.

The meat toilet fertilized egg, having responded to countless demands, was forced to grow to an unnatural size. Yet it still wasn’t enough. The larger it became, the more countless sperm swarmed around it, entering freely as though it were their own home, pouring out their reproductive urges. There were no more resisting—only complete surrender to their will.

The toilet-like fertilized egg, having its body used at will, bravely accepts it, and over time comes to believe that this is normal, that this is how things should be.

Having expanded past its breaking point, the toilet-like fertilized egg is at last freed from the sperm’s assault. Yet, it’s far from over.

Collared like obedient slaves, the four meat toilets are taken by the sperm and cast into the uterine wall, where they successfully implant. Touched by the sperm’s kindness in preventing any implantation defects, the flesh slaves release mucus of joy. This is the moment they transform into slime cores.

The slimes embed their tentacles into the host’s body, steadily drawing nourishment as they grow—awaiting the day of their eventual birth.

This time’s results:

– Impregnated Rio with four slimes.
