I’ve Been Reincarnated as a Tentacle Slime~ I Want to Live a Comfortable, Secure Life and Do Whatever I Want~ - Chapter 129

While I was leisurely walking to the mating room, I ran into the sister who had let me grope her br3asts earlier.

“I’ve been waiting for you. I asked four sisters to wait for you in this mating room.”

Even though she was so worn out, yet she still managed to bring them together for me. Even now, her legs are trembling a bit and she seems barely able to stand…

“Thank you. It looks like I ended up pushing you too hard.”

“Oh no, not at all. It’s a wonderful thing that you’re trying to impregnate girls with available wombs. I also heard you made a generous donation as well. As a priest, it’s only natural to work hard for a devoted believer!”

I don’t consider myself a believer, but I don’t intend to say anything tactless. I’ll accept it gratefully.

“Come now, please step inside!”

When I stepped into the room―――― I saw four pussies lined up side by side.

Maybe there’s a slight misunderstanding in the way I phrased that.

There were four women with their hands on the desk, legs spread, their backsides turned toward me, lifting their nun outfits to fully expose their pussies.

I couldn’t see their faces, but from the left, there was a rabbit-eared girl, a human, an elf, and a petite girl who appeared to be a dwarf.

“All of these girls have empty wombs waiting to be fertilized. Please insert your p3nis into these four female holes, stroke yourself, and shoot your semen into their wombs. It’s even better if you ejaculate inside their vaginas twice each.”

Without properly listening to the sister’s words, I pulled down my pants and suddenly shoved my p3nis into the rabbit-eared sister on the left. I was having s3x with her raw within 5 seconds of meeting her.

“Hyah! So sudden! Nhaa♡ And it’s really intense!”

Startled by the sudden insertion of my p3nis, the rabbit-eared sister’s v4g1na clenched tightly.

“The tightness is pretty good. I won’t be able to stop moving my hips.”

Using a p3nis slightly larger than the rabbit-eared sister’s v4g1na, I thrust into every part of her v4g1na, relentlessly attacking her cervix.

“Nn! Your p3nis is rampaging inside my v4g1na♡ Ah, ah♡ Don’t knock so hard on the baby’s room…♡ No one is in there yet♡”

I relentlessly thrust into the tightly stretched pvssy of the rabbit-eared sister. That way, I feel good, and she can get pregnant by being filled with my creampie inside her. It’s a win-win relationship.

“My pvssy is so full of your p3nis, it’s spreading and stretching wide! Ah, again, your p3nis has grown bigger!”

As the rabbit-eared sister’s pvssy stretches, my p3nis gradually grows bigger. With each thrust, her round tail and rabbit ears sway back and forth. I reach out to her tail.

“Haah♡ Haah! No♡ Please don’t grab my tail…♡”

Every time I squeeze her tail, the inside of her v4g1na contracts tighter and tighter. I’m on the verge of ejaculating.

“It’s fine, isn’t it? Gripping the tail makes it feel better, right?”

“Yes! Yes! Ah♡ The tip of the your p3nis is swelling… nn♡ Semen! Semen’s is going to come out♡ Fill my pvssy, no fill my womb with lots of your ejaculation!”

With one final thrust, I push my glans deep into her cervix and start ejaculating.

Spuuuuuuurrrrrrrrrrttttttttt――――!!!!

“Nnhaaaa aaaah――――!!!”

At the same time as I ejaculate, the rabbit-eared sister orgasms, her hips jerking! jerking! and springing up, her v4g1na squeezes tightly. Even though my p3nis feels like its being crushed, a large volume of semen is forced through my urethra into her v4g1na.

This time, I stuffed about one liter into her womb.

When I pull out my p3nis, the rabbit-eared sister’s v4g1na remains stretched in the shape of my p3nis, twitching and convulsing as it contracts and expands.

Her cervix, which was completely visible, opened and closed. Each time, semen spurted out of her cervix like an ejaculation, soaking into the folds of her v4g1na.

I slid my finger into the fully opened v4g1na of the rabbit-eared sister and rubbed her vaginal folds with my finger. The sister twitched, the vaginal folds mistakenly thinking a p3nis had arrived, clenched tightly. Since it was a rare chance, I smeared the overflowing semen inside her v4g1na. Then, the rabbit-eared sister squirted with delight.

–

“Alright, I guess that’s enough for her? Next is…”

I turned to face the human sister, who’s pvssy was dripping wet to the right of the rabbit-eared sister.

“U-Um… Please be gentle… alright?”

Seeing the rabbit-eared sister beside her with her lower abdomen bulging and gasping for breath, the human sister is scared that the same might happen to her.

“Yeah. It’ll be fine.”

Hearing my words, the human sister seemed relieved but――――

“I’ll make sure it feels great, and then I’ll give you a generous creampie.”

“Ah… It seems like it’s no good. …Nnhaa♡ Your p3nis is coming in…♡”

She seemed to have given up after hearing that I didn’t understand, or that even if I did, I wouldn’t go easy on her.

Her v4g1na was slick and writhing, behaving like it was fawning over my p3nis.

I change the shape of my p3nis covering it in bumpy protrusions to give pleasure from various angles to the entwining lustful flesh.

“Fah…♡ Your p3nis♡ Amazing…♡ The inside of my pvssy is all soaked and being stirred up…♡ I’ve never felt something like this before.”

When penetrating her v4g1na, her folds guide me deeper and deeper. When pulling out, the folds catch on my p3nis as if unwilling to let go.

If the rabbit-eared sister feels like she’s stroking my p3nis, then the human sister feels like she’s caressing my p3nis.

“The inside of sister’s v4g1na feels good too. Unlike the rabbit-eared girl’s v4g1na, it clings to my p3nis with a slippery touch.”

“Ah…♡ Please don’t say that… Everyone is listening.”

(Inside this v4g1na, high-speed thrusting feels better than stimulating the vaginal walls. The way it clings to me while pistioning feels great.)

I firmly grabbed her hips and――――

“Hah…♡ Nn? C-could it be… I-I told you it’s no good―――― Nnnnngghhh Aaaahhh――――!!!”

With rapid pistoning, I stir up the inside of the sister’s v4g1na into a messy state.

The lustful flesh inside her v4g1na, surprised, still tries its best to keep up with my thrusts and clings tightly to my p3nis.

“Ah! Ahh♡ Nnngh!! Nooo! I can’t stand up anymore…♡”

The human sister’s arms and legs shake uncontrollably, her upper body falls onto the desk as her arms can no longer support her. Her lower body goes limp, but I hold her hips firmly, so she’s still positioned with her butt pushed outward.

“It feels really good. Is it okay if I ejaculate now?”

“Yes…♡ Hahii♡ Please give me lots…♡ With your brutal c0ck, make me pregnant――――!!!!”

Spuuuuurrrrrrttttt――――!!! Spuuuuuurrrrrrrttttt――――!

I stuffed about a liter of semen into her v4g1na.

Then, when I pulled out my p3nis, her v4g1na remained gaping wide open, and the folds of her lustful flesh were immersed in the sea of semen that had accumulated inside her v4g1na.

“Fah…♡ It’s so warm inside my belly…♡ Huu…♡ Huu…♡”

The human sister remained slumped over the desk, unable to move. She had been pushed to climax so many times that her legs and lower body couldn’t support her.

–

“Now, it’s your turn, Elf.”

I grabbed the elf sister’s slender waist and thrust my p3nis into her v4g1na.

“Nnnnn――――!! Th-that, I’m, cuuuuuummmmming♡”

The elf sister seemed to have came just from having my p3nis inserted.

Inside her v4g1na, there is a roughness that feels immature.

“You see, this girl has a constitution that makes her cum easily. Since she only became a sister this year, her v4g1na is still rough, right? Nobody’s gotten her pregnant yet, so make sure to impregnate her properly.”

The dwarf sister beside me provided some additional information.

“Oh, this will be your first time getting pregnant? Then, I’ll make sure to get you pregnant properly, so open your cervix wide.”

I persistently thrust into her cervix.

“Nn-ahh!! Nkuh!! Aahhh――――!! I’m already cumming a lot♡♡ Your p3nis is amazing♡♡♡ My womb is being knocked so deeply and hard♡♡”

The elf sister, shaking her head wildly, is fully taking my pistoning.

Already, her hands and feet are trembling uncontrollably, as if desperately trying to accept the pleasure.

“Haa♡ Aaah! NnnnnnNnnnnn――――!!! …Aah…♡”

The inside of her v4g1na, which I was grinding roughly, tightened even more, and the elf sister collapsed face-down on the desk.

“Oh dear… You passed out because it felt too good, huh? It’s okay to keep fucking her just like that.”

The dwarf sister kindly advised, but—

“Yeah, I had no intention of stopping.”

Using the inside of the elf sister’s v4g1na who had passed out and gone limp like a living onahole, I stroked my p3nis.

“Uahh…♡ Ah…♡…♡ Aaah…♡ …♡”

The elf sister could only moan and gasp from being penetrated.

The inside of her v4g1na trembled and quivered, just like a virgin girl enduring rape.

I mercilessly thrust into her v4g1na, forcing the cervix to open against its will.

My p3nis that had penetrated the cervix stopped its violent thrusts and shifted to a slow, rubbing motion as if it was trying to lick the inside of her womb.

“It feels good to train her. She’s so hypersensitive to my movements.”

I insert my p3nis into her womb and move my hips as if I’m licking the inside of her uterus.

Then, I piston her v4g1na and the inside her uterus with long strokes to build up pleasure for my ejaculation.

“Aaah…♡♡ Auu…♡ Nnn…♡ Fuaaah…♡♡ …! …♡ Ah♡”

I pulled my p3nis out to the very limit, then thrust my p3nis all the way into her womb in single motion. Along with a wet smack sound, the elf sister climaxed, and her body spasmed.

As if in place of her moans, she squirts a gush of fluid loudly onto the floor.

“You probably can’t hear me, but I’m going to ejaculate!”

I thrust my p3nis all the way into the depths of her womb, and as her womb bulges, I start ejaculating as if delivering the final strike.

“Oh~ That’s an amazing creampie. The shape of your p3nis is completely visible on both her pvssy and womb.

The Dwarf Sister explains the situation of the creampie.

–

“Now, it’s your turn.”

“Yeah, I’ve been waiting. Come on, hurry up and shove your p3nis in, insert it already.”

The Dwarf Sister is spreading her pvssy wide by herself, inviting my p3nis.

“Well then, excuse me.”

I sink my p3nis into her small, loli-shaped pvssy.

“Oh, it feels amazing.”

The inside of her v4g1na feels all squishy and bumpy, and my p3nis feels like it’s wrapped in something soft.

“Big brother, your p3nis is so big! It feels so good♡ Hahh…♡ And I can do this too!”

At that moment, her v4g1na clenches tightly and the bumps start rubbing up against my p3nis.

“Woah, what an amazing v4g1na!”

The loli (dwarf) sister shakes her hips by herself and gives me pleasure.

If things keep going like this, I’ll end up completely at her mercy cumming whenever she wants, so to fight back I’ll make my p3nis bigger and cover it in bumps.

“Fah! Ah♡ Really, you have such an amazing p3nis! Hahh♡ I’ve already given birth to 14 children, but this is the best, hyaa♡ p3nis!”

The one I thought was the biggest loli turned out to be the oldest at 35 years old. Her v4g1na, which undulated like a living thing, must have come from her experience.

I thrust my hips with single-minded focus, trying to make the loli (dwarf) sister cum at the same time as me!

“Ah♡ Ah♡ Ahh! It feels so good♡ I’ll never be able to forget this! Fahh! Your c0ck has gotten bigger! Are you going to cum? Are you going to shoot your semen inside my pvssy?”

“I can’t hold back anymore! I’m going to cum!”

Unable to hold back, I ejaculate a large amount of semen into the loli (dwarf) sister’s v4g1na.

“Aahhh♡♡ Faaahhh—!!!”

Her small body twitches and she squirted violently.

Thank goodness, it seems we somehow managed to cum together.

When I pull out my p3nis, her v4g1na is also open wide, but it seems to be opening and closing tightly.

All four of them have their pussies spread wide open, but the loli (dwarf) sister seems to be writhing in the most pleasure.

“Haaah…♡ That felt amazing♡”

The loli (dwarf) sister is blissfully resting her body on the desk. Maybe she was feeling post-coital fatigue?

After everyone’s first ejaculation, the modification of their v4g1na’s and uteruses’ took place.

Their v4g1na’s are transformed into a masterpiece, with erogenous zones laid out inside their v4g1na like a web, allowing them to enjoy themselves as well, it’s a win-win.

The modification of the uterus was gentle, and it now stretches flexibly as usual, but there was no change in the ovaries. The fallopian tubes, however, now have a sperm colony, with the primary function being sperm preservation.

That’s right, this time it’s not about a mass slime birth, but about getting pregnant with a human child.

I’ll be overwhelmed with managing the Adventurer’s Guild, the public bathhouse, and the slaves I’m going to buy.

Therefore, the modification of the ovaries is unnecessary, and sperm exists solely to provide nutrition for the child. That’s why I made the modification capable of producing it for an extended period.

–

After that, we did one more round of raw s3x and I ejaculated inside them again, and all four of them were thoroughly impregnated with twins.

To prevent a miscarriage, immediately after implantation, the sperm enters the fertilized egg and is broken down as nutrition.

Then, the fertilized egg rapidly begins cell division and grows in the blink of an eye.

In order for the fetus to develop normally, the sperm are gradually consumed.

The women who became pregnant this time will give birth about a month earlier, but since multiple births generally have a shorter pregnancy period, it shouldn’t be a problem. They will, however, develop and give birth just as fully as if they were carrying one child, but it shouldn’t be a big issue… I think.

–

“Cruz-san! You’ve done a lot of vaginal ejaculations. I’m sure they’re pregnant for sure. Thank you for your hard work!”

The pregnant sister with large br3asts, who had been waiting outside, came into the room.

“So, I have a request… Could you impregnate these women as well? They’re followers of the Dungeon religion, but the other men are quite occupied…”

The sister attempted to introduce the two female adventurers who entered with her.

“Okay.”

I used [Swift Wind] to approach one of the adventurers, quickly removed her pants, grabbed one of her legs, and thrusted my p3nis into her.

“Ah♡ I haven’t even introduced myself yet, and I’m already being fucked♡”

–

In the end, I ended up with a few more women after these girls, and eventually, including the four sisters, I made 11 women pregnant with twins.

For the first time, I made another being pregnant with something other then a slime.

I became able to use my own semen to accelerate the development of a fetus.
