I’ve Been Reincarnated as a Tentacle Slime~ I Want to Live a Comfortable, Secure Life and Do Whatever I Want~ - Chapter 26

When I woke up, the food for the baby slimes had been significantly eaten. At this rate, they’ll probably finish it all by the end of the day.

Oh, also, a new trait called [Progenitor] has appeared. It seems I can grow stronger with the number of family, but with only four, it didn’t feel any different. I figured I wouldn’t notice the effect for a long time, so I decided not to worry about it.

I also have something to confirm when making a core. During the last mating, I felt with my tentacles that two nearby cores were being pulled together. I didn’t know what might happen, so I separated them, but now I want to try an experiment to see what would happen if they were allowed to draw closer.

While thinking about such things, I spent today hunting and eating everything on my own, before finally getting to breeding time.

The baby slimes must have been considerate, as they were bringing food into the Monster House, moving from the gate room. Well, it’s helpful since I don’t want to be seen by someone I can actually converse with.

◆◆◆◆◆◆◆

I laid Rio on her back on top of me and bound her limbs and body with my tentacles. Her hips were pushed upward, and her arms and legs were spread wide in a starfish position, against my rounded form.

“Today, are you going to do the breeding while still being your usual self, Master?”

“Yeah, that’s right. I will normally impregnate you in my slime form. You can consider the humanoid shape as something I use only when I feel like it.”

The slime form allows me to do a lot of different things.

I extended two tentacles and made them latch onto her n1pples and suck.

“Mmm, Master. Please suck a lot again today.”

Using [Adhesion], I began drawing milk from her br3asts. This time, like a milking machine, the area around her n1pples was hollow, and the breastmilk shot out, collecting inside the cavity. Her still-small chest quickly emptied all the breastmilk.

I absorbed the br3ast milk, which barely filled half a small glass, into my slime body. I relished the sweet flavor of the milk and spread my tentacles over her small chest.

“Are you going to make my b00bs bigger again?”

“Yeah, it’s been around three days, and it looks like the size has stopped changing.”

“Please! I want you to make them bigger!”

I surrounded her n1pples with a circular brush, similar to a paintbrush, and rotated it at high speed.

“Ahhhhhh♡♡♡ Haah♡ Ahh♡♡ Ahii♡♡♡ My n1pples are as stiff as a p3nis♡♡♡ It’s getting so hard♡♡♡”

As Rio said, her n1pples receiving training from the brush tentacle are rock-hard, and the hardness amplifies the pleasure from the brush even more. Additionally, the extremely thin tentacles invade from the br3ast openings to the milk ducts and mammary glands.

“Hah♡ Hah♡ Hah♡ Inside my b00bs♡♡ So many cocks have been released♡♡ My chest is going to get pregnant♡♡♡ Nnnn――――ahhhh!!♡♡♡♡”

She is forced to cum with only her n1pples, trying to escape the pleasure unconsciously, but since she is restrained by the tentacles, she can only writhe, which makes it look as if she is actually trying to entice them.

Rio wants the ejaculation mucus, so I will ejaculate into her mammary glands and ducts. It appears that both the number of milk ducts and the size of the milk sacs have increased since the previous invasion, as more mucus fills the br3asts compared to before.

“Ahh♡♡ It’s coming out♡ In my b00bs♡ I’ve been dominated by Master♡♡♡ Please make my b00bs bigger♡ I’ll make lots of milk just for Master♡♡♡”

When finally pulling out the tentacles, soft brushes grow around it, stimulating the milk ducts as they move up and down while being pulled out.

“Nfuu♡♡♡ Master is going out from inside my b00bs♡♡♡ Nfii♡♡♡ You shouldn’t be playing in the milk passage of my b00bs♡♡♡ Ahhh—!! Haah♡ Haah♡ I can’t tell if it feels good inside my n1pples or in my br3asts♡♡♡♡”

By developing inside her n1pples, and at the same time working on her br3asts, Rio’s mind is brainwashed into thinking that the pleasure only exists within her br3asts.

Then, the long-awaited moment arrives, as I extend a tentacle toward her pvssy. This time, the plan is urethral development and womb expansion. In the end, I’m wondering if it’s possible to impregnate inside the bladder. If I move the slime core there, I think it will take root. Unfortunately, the intestines can’t be impregnated because of the nutrient-supplying s3x.

“Well then, it’s time for the long-awaited baby-making.”

Rio’s legs are fixed in place by the tentacles, spread wide in a large ‘X’ shape, fully extended. I use two tentacles to pry open and hold her pvssy in place, while a tentacle covered in bumps rubs up and down on her pvssy.

“Fuaa, my pvssy is gradually heating up from deep inside. Master’s bumpy tentacle is making me feel all light and floaty.”

Unlike the n1pple brush, Rio surrenders herself to the gentle pleasure. After a while, I’ll get Rio worked up like this before proceeding to the next step.

“Huh, huu… Nn… Master… Ah, more… Hii, I want you to tease me more… The pvssy that Master trained… Nn, more… Nn… I’m begging for it…”

As Rio grows increasingly unsatisfied, she starts begging me. Her vaginal opening opens and closes, and her love juices have been overflowing since earlier. Then, in an attempt to find pleasure, she moves her hips just a little, rising and falling in time with the tentacle’s movements.

“Such a naughty girl. At your age, begging for s3x, not even a s3x slave would do that, right?”

“I’m sorry, but… nhi, after receiving Master’s training… Ah, anyone would become a lewd girl… Ahh, I’m begging you please put it in…!”

“Well then, there’s a way to beg, right? If you want me to put it in, what do you say?”

I swayed a p3nis-shaped tentacle in front of Rio’s eyes.

“Please insert Master’s p3nis and fvck it into Rio’s Master’s exclusive pvssy♡ Feel good with Rio’s living onahole and irresponsibly ejaculate your boy semen to my girl womb♡♡♡”

“Well then, I’ll do as you wish, here you go!”

The instant I uttered the words, a tentacle was pushed into Rio’s v4g1na. The pleasure inside her v4g1na exceeded that of before, with the softness and hardness of the lewd flesh, and the bumps and slippery sensations assaulting from all directions. The inside of the v4g1na was tightly closed, offering the pleasure of piercing and digging its way through, and when the p3nis was pushed in, various pleasures assaulted the glans.

“Ahh♡ Master is coming in♡ My pvssy just wants to serve Master, it moving all on its own♡♡”

Rio joyfully moved her hips. Her pvssy that was deeply engulfing the thick p3nis was stretched tight. From this sight alone, she looked like a completely trained s3x slave.

My p3nis tentacle parts Rio’s erotic flesh and finally reaches her cervix. Struggling not to climax, I thrust the p3nis into cervix. The cervix rejoices at its master’s return, clinging to the p3nis with a rough, textured surface. This becomes the final push, leading to ejaculation.

“The long-awaited ejaculation is here!”

From the p3nis tentacle, a large amount of semen is sent into her womb.

“Ahhh♡♡♡ With Master’s p3nis ejaculation, I’m going to cum♡♡♡ Splurt Splurt When my womb is pounded, my pvssy tightens♡♡ I’m cumminggggg♡♡♡ Ahh♡ Ahhh♡ Ahhh♡♡ I’m cumminggggggg!!!♡♡♡♡”

After achieving ejaculation, Rio’s pregnancy-desiring womb tightly encloses around the glans, sending the semen deeper and deeper inside. With a spurting splashing sound, semen fills the uterus and clings to the uterine walls, soaking in. As the walls of the uterus thicken and become more flexible, it allows for a larger expansion of the uterus.

I pull my p3nis tentacle back to the vaginal opening, then strike the cervix with full force. Unable to resist, I ejaculate, but I had no intention of expressing myself anymore and ejaculated silently. Having received the reward, the cervix takes the p3nis into its opening and leads it inside the womb. In opposition to that, I pull back and thrust once more. Her womb seemed to understand my intent and stopped trying to guide me and willingly accepted being pounded and pried open. I slam into the womb-pvssy repeatedly, ejaculating each time. Every time the womb is penetrated, it tightens with a Squelch♡ Squelch♡, as it rubs and stroke the tip of my p3nis, causing me to ejaculate as I pull out.

“Ohh♡ Ohhh♡♡♡ Your p3nis is rubbing♡♡ My womb-pvssy is being punished♡♡ It’s clinging to Master’s p3nis♡♡♡♡ Ohh♡♡ Even though I’m cumming a lot♡♡♡♡ Your p3nis is scrubbing it hard and I’m going to cum again―――♡♡♡♡♡”

After digging through the womb-pvssy, I eventually arrive at a wide chamber, in the inner part of the uterus.

“Ahhh♡♡♡ It’s in now♡♡ P3nis-sama has arrived at the impregnation room♡♡♡”

Rio, jerking her hips, was delighted that my p3nis had entered her uterus.

I pull my p3nis tentacle back to her vaginal opening. Then,

“Ahh♡♡♡♡ It’s coming♡♡♡ My stomach feels like it’s being punched, it feels like it’s going all the way to my head, something incredible is coming—ahh oohhh♡♡♡♡”

Before she could say everything, I forcefully drive my p3nis into her v4g1na and cervix, slamming into her womb-pvssy. The womb stretches, and the shape of p3nis appears on her abdomen, about 10cm deep.

Rio squirts vigorously, as she convulses with an expression of pleasure, trembling in spasms.

At this moment, I begin to gently probe the urethral opening with a thin p3nis tentacle, about the size of a cotton swab. Simultaneously, the p3nis tentacle bends and begins to pierce the uterine walls, causing the stomach to bulge. As the stomach bulges, I gradually begin to probe the urethra, coating it in mucus, and only then does Rio notice. After all, even if she tries to squirt, she can’t, and it goes back inside her body. There’s no way she wouldn’t notice.

“Ah~♡ Ah~♡♡ Ahi~♡♡♡ My womb is also Master’s toy♡♡♡ ————??? I can’t squirt, it’s not coming out♡♡♡!? Master, that’s where I pee, not a place for doing that♡”

I thought she would dislike it, but her reaction seems better than I expected. It might just be because her mind isn’t functioning properly, though.

“What are you talking about? There’s a hole here too, so there’s no way it’s impossible, right? Come on!”

I pull the tentacle back to the urethral opening, then forcefully push it back into the same spot with a thud. Of course, I continue to piston inside her v4g1na.

“Ahhhhhh♡♡♡ It’s strange♡ How can I feel good in the place I pee♡♡♡ It’s so weird♡”

“There’s nothing strange about it. If it feels good, you should just accept it as it is.”

Alternating between pistoning her urethral opening and the pistoning her pvssy, I repeatedly insert and remove the tentacles, ingraining the pleasure of urethral s3x into Rio’s mind.

“Ahhhhhh♡♡♡♡ It feels so good in my pee hole♡♡♡♡ I just came from my pee hole――――♡♡♡♡”

While watching Rio’s urethral orgasm, I dig into her urethra and finally reach the bladder. The tide flows backward, invading the bladder and becoming swollen. I absorb everything with the tentacle and replace it with half the amount of mucus. Then, I resume the urethral pistoning from the opening to the bladder.

“It’s no good♡♡♡ If my pvssy and pee hole get all stuffed♡♡ I’ll end up getting all silly in the head♡♡♡♡”

I can’t tell which pleasure is stronger, the pvssy pistoning or the pee hole pistoning, and I end up ejaculating inside the urethra.

“Ahhhhh♡♡♡♡ My pee hole is getting filled with semen♡♡♡♡ The pee orgasm feels good too♡♡♡♡”

Since I was able to develop her ability to climax with her urethra, let’s go back to expanding the uterus.

Until now, there was only one tentacle, but since I’m using my slime body, there’s absolutely no need for just one. I create three new tentacles and insert them one by into the depths of her v4g1na, hitting each of her pussies.

“That’s just too much for me♡♡♡♡ Nnngh♡♡♡♡――――Aahh♡♡ Nnnghngh♡♡♡♡♡ ――――Oohh♡♡”

“It’s not spread as wide as it was during childbirth, so it’s fine!”

The four tentacles are inserted into Rio’s pvssy, and it must feel as if a 500ml plastic bottle is being pushed into her pvssy. The fact that the tentacles are transparent makes it feel even more so.

Three tentacles pass through the inside of her v4g1na, and the bulge in Rio’s pvssy on top of her stomach clearly shows how far they’ve penetrated, even from the outside. The urethra p3nis is compressed, intensifying the pleasure, and Rio rolls her eyes back, gritting her teeth from the overwhelming sensation.

Experiencing the pleasure from four tentacles, I finally make my way to her womb, spilling semen as I move. I hit the cervix with my climax, then strike the cervix with my glans. The womb opening wants to open its mouth to take it, but since they can’t stretch any further, they stop serving the tentacles within the womb and get ready to accept the actions of the tentacles—the master of the womb.

The tentacles first narrow at the tip before entering the cervix, and then gradually return to their full thickness. The cervix can only twitch and spasm, unable to handle the overwhelming expansion. As the tentacles slowly advance millimeter by millimeter, four of them settle inside the uterus. Just when it seems like they will start pistoning, the tentacles begin to inflate inside the uterus, like balloons. The uterus swells rapidly, expanding beyond the size it reached in the last month of pregnancy.

“Ahhh♡♡♡♡ Ohh naaaa gahhh♡ My beloved master♡♡♡♡ I’m going to burst♡♡♡♡”

The sensation is being transformed into pleasure through the mucus, but with this size, it certainly looks painful. I resume using the n1pple brush, trying to distract her with the pleasure.

–

After about 30 minutes, Rio had grown used to the expansion of her uterus and started letting out soft moans.

“Ohoooo♡♡♡♡ The uterus wants to become pregnant♡♡♡ The egg’s chamber wants to ovulate♡♡♡♡ It’s trembling♡♡”

Out of the four tentacles, one is returned to a p3nis shape, two are thinned out to control the ovulation from the ovaries, and the last one is used for an experiment on the core.

Having been repeatedly ejaculated in, Rio’s uterus has become a storage place for semen, and when an egg arrives, it will be fertilized instantly. To direct the egg to this uterus, two tentacles travel to the ovaries. The ovaries, eager to ovulate, are granted permission by the tentacles and start releasing eggs one after another.

Ten eggs are transported by the tentacles to the uterus. Realizing their fate inside the uterus, the eggs are surrounded by sperm and quickly fertilized, becoming embryos. The sperm’s feast has only just begun. Over a trillion sperm repeatedly violate the fertilized eggs. Human genetic information is brutally altered, transforming into something not human… into the genes of a slime, transforming into a slime core.

Then, using the experimental tentacle, two cores are captured and brought together. As a result, the two cores merge and fuse, transforming into a single core. However, there doesn’t seem to be much of a change. The size remains the same as before the fusion. For now, I decide to fuse the remaining eight and check if there are any changes, but they only merge into four.

Is it possible to fuse the core that has already been born with the fertilized egg core?

From among them, I take one out of the uterus and press it against my core. Then, the fertilized egg core is absorbed into my core. I want to check the effect, but since I still need to impregnate two more, I’ll put it off for now.

The remaining four slime cores are implanted into Rio, and the tentacles begin absorbing nutrients from the walls of the uterus. After that, four new eggs are ovulated and brought to the uterus. The four eggs, upon seeing the state of the uterus, tremble, realizing they are destined for the same fate.

The premonition, no, as expected, the eggs are overwhelmed by the sperm, with countless sperm entering the eggs and staying there. While inside, the sperm repeatedly inject genetic information, making the eggs realize they are nothing but the sperm’s playthings. The large number of sperm inside the eggs causes the egg’s genetic structure to be changed by the male genes. The fertilized egg, having been played with, turns into a slime core, and two cores fuse into one, creating a new core.

Thus, within Rio’s uterus, the six slimes will continue to grow until the day of their birth.

This time’s results:

・ This time, Rio was impregnated with 6.

・ By absorbing the fertilized egg core that has just become a core, it is possible to have multiple cores in one body.

・The same principle applies when fertilized egg cores are fused together.
