Prologue

Somewhere in Tokyo at a Doujinshi conference.

"Yokubo-sensei, I'm a big fan of yours~," a girl in Marin Kitagawa cosplay said with a sultry, seductive tone to the man in front of him.

"Thank you very much," Yokubo thanked her while taking the stack of erotic manga from her to sign.

Yokubo was a famous doujinshi artist.

While his fans consisted mostly of degenerate men with weird kinks, sometimes there was an equally perverted woman among them.

While he was signing his works one by one, he noticed that the girl in front of him was blushing and breathing heavily as if she was in heat.

Seeing this, he could only smile, which made her blush redder than before, and he swore he could see her eyes turn into the shape of hearts.

"Nee~, would you like to have a drink with me later, Sen~sei~?" she said, her words full of lust.

Yokubo smiled and said jokingly, "Sure~"

The two kiss each other as they enter a hotel room.

There is an aura of passionate desire between them.

While kissing, they quickly undress each other.

While they're at it, Yokubo's hand stated to explore her F-Cup breasts, while slowly untied her bra.

In return, her hands began to take of his pants revealing a big bulge.

The two lovers were lost in their own world of pleasure and desire. Their bodies intertwined, they explored each other's every inch.

Yokubo's hands roamed over her curves, sending shivers down her spine.

She moaned softly as he kissed his way down her neck, his lips leaving a trail of fire in their wake.

As they moved together, their passion grew stronger, until they were both consumed by the intensity of their lust.

She then kneeled and pulled his boxer, revealing a raging dick as big as her face.

"I've never seen anything as big as this~, here i thought my boyfriend was the biggest~" She said in amazement by her size of the dick that's going to fuck her tonight.

Yokubo's eyes shone with pride as he watched her admire his manhood. He couldn't wait to feel her tightness around him, to make her scream and moan with pleasure.

He pulled her to him and kissed her deeply, his hands roaming over her body as she gasped into his mouth.

They fell onto the bed, their bodies intertwined as they explored each other's desires. Yokub took his time, savoring every moment of their lovemaking, teasing and tantalizing her until she begged for release.

"PLEASE FUCK MY CHEATING PUSSY RAW!" She pleaded, her voice hoarse with desire.

Yokubo obliged, thrusting into her with a ferocity that left her gasping for breath.

He pounded into her relentlessly, his hands gripping her hips as he drove himself deeper and deeper into her.

She screamed in ecstasy as he brought her to the brink of orgasm again and again, pulling back at the last moment until she was begging for release.

Finally, unable to hold back any longer, Yokubo gave in to his own desires and exploded inside her, filling her with his hot cum as she screamed in pleasure.

And then a bright light shone and a magic circle suddenly appeared.

Urrgghhhh.....

What the hell happened....

The last thing I remember is being in a hotel...

Did I pass out?

No way, right....

But that doesn't explain the hallucinations I was having.

Suddenly a mass of information became available to me.

As if I had discovered a new place in my mind that contained the said information.

The new information is from [Dark Sage].

Unlike the [Great Sage] that Rimuru had, [Dark Sage] had no ego.

It was like another you doing the work of [Great Sage], or your subconscious self doing it.

It must've felt weird, but he might have been more flexible than [Great Sage].

I don't know how it feels to have another ego living inside of you.

How does [Skill]s work?

A series of information became available to my mind, and I was able to understand it immediately.

Skills are abilities granted by [Voice of the World] that are tattooed on one's will.

Since there is no [Voice of the World] here, there is no one to grant [Skills].

Therefore, they can no longer be earned, but have to be learned or won, and then slowly engraved into one's soul.

Basically, [Dark Sage] is going to engrave everything I learn bit by bit, and when it's finished, it's going to turn into a skill.

So I have to grind it.

Not that I'm complaining.

It's better than being born without a skill.

Speaking of being reborn, my skills are [Dark Sage], [Eromancer], and [Broken Hero's Egg: Pseudo Divinity].

The Eromancer was pretty self-explanatory, but the Broken Hero's Egg was pretty unique because it contains Pseudo Divinity.

That is, I'm a newborn god with no followers yet.

And if I gain followers, I can grow my divinity!

Anyway, my body feels strange right now.

It's round.

Squishy....

Slimy.....

I'M A SLIME?

Another set of information fed into me, basically confirming that I'm indeed a slime.

Welp, it was long and detailed, mushed up in a split second.

More efficient than a voice explaining it to you, I suppose.

I tried to move, which resulted in me rolling around because I have no legs since I'm a slime.

Also, I can't see.

You can imitate a human from my memories alone.

After receiving the confirmation, my body suddenly changed shape, looking more humanoid, like those statues in a clothing store.

Then I felt bones, muscles, and organs forming, and slowly I could see again.

When my eyes finished forming, I looked around and saw that I'm in some kind of abandoned shrine.

It's pretty beat up, like no one even bothered to take care of it.

Then I inspect my own body.

Well-toned skin and proportionate muscles.

But I see nothing... my little brother didn't survive the legendary Isekai.

Oh, right, slime are genderless.

I ordered [Dark Sage] to form a fully functional male reproductive system, also known as a penis.

And the final product is... average.

I commanded again to make it longer, and it grows...

WAIT!

STOP NOT SO LONG!

And I commanded to make it shorter, I don't want my dick to be 1 meter long.

BUT NOT THAT SHORT, as I see it shorten to 3 inches.

What I didn't realize at that time was that a certain woman was watching me lengthening and shortening my dick as if it was Sun Wukong's magic staff.
