The Devil's Origin

6: Slime. (NSFW)

After waiting a while, the trembling Slime finally arrived at the Devil's Castle.

So this is a Slime.

A dark orange core floated within a plump, lemon-yellow, jelly-like body. It was a jelly that looked good enough to eat.

Hesitantly, I reached out to touch it. The jelly was cool to the touch; I wondered if it would stay cool inside me.

I don't know if Slime can melt clothes, but just to be safe I'll undress first.

When the Slime seemed to realize I was harmless, it boldly oozed up my legs. In only a moment, the cold jelly reached my hips.

Part of the Slime oozed upwards and touched my cheek as if to caress it before pushing between my lips. I think my mouth must be very sensitive; this is nothing like a kiss, and yet it feels comfortable.

While I was focused on the slime in my mouth, the slime draped around my thighs began to move.

"Hah!"

Something soft wrapped itself around my dick.

As it rubbed against me, my hips subconsciously began to move.

Through the growing haze of arousal, I felt a strange sensation. I snapped to attention when I realized the Slime was squeezing into my urethra. That is not an entrance.

"Hey!"

The slime that entered the urethra smoothly stimulated both the outside and inside of my dick at the same time. It made me want to cum, but I couldn't, and I was ashamed of my frustration.

The slime in my mouth wriggles further in, pouring itself down my throat. It stings a little.

As the cool slime accumulated in my mouth, I shuddered; what would happen if I accidentally bit it? If I inadvertently bite through the slime, and it somehow reaches my stomach... Thinking about it, I opened my mouth as wide as I could.

Despite my fear, I sighed when something touched my butt.

The sphincter muscle, which had already returned to its original state, did not open easily. The Slime finally managed to squeeze in some jelly about the size of an index finger. Compared to Velke, the insertion felt quite modest.

But that was only the beginning.

"Haahh!!"

From the index-finger-sized gap, an unbelievable amount of slime poured in! At the sudden expansion, tears flowed uncontrollably down my cheeks. The Slime reached a point not far from my entrance and forcibly stimulated it. How could it have known where my prostate was!?

It oozed up my passage without difficulty and passed through the membrane of my womb; enough slime was gathered in my belly that it began to swell and bulge out.

The Slime moved as though it knew where I felt good.

Hah... Mm, ah!

The slime in my belly was soft, but it pressed inside me with unbelievable mass.

Even the slime in my mouth was heavy; I tried to touch it with my hand but I couldn't get a grip on its slippery body.

If it's a Slime, mating will be easy... It seems my previous assumption was a mistake.

Although I really wanted to cum, the slime piercing my urethra wouldn't let me, rubbing both the inside and the outside. Although my entrance has only stretched a little compared to yesterday, the mass inside me is enough to distend my belly. Endlessly shifting, the jelly-like slime moved within me. It felt as though this would never end.

The Slime's relaxed mating continued until dawn.

<<Congratulations! You have Leveled Up!>>

+ 1 Level
+ 5 [Soundless Voice]
+ 20 Slime Eggs

<<With this, you have mastered the skill [Soundless Voice] >>

After my long night with the Slime, a bright voice echoed in my head.

Satisfied, the Slime finally slipped out of my mouth and urethra. The cum that had lost its momentum leaked out slowly. At last, the jelly that was stuffed into my intestines drained back out through the hole that was still only about the size of an index finger.

Now that the Slime is out, I feel uncomfortably empty. More importantly, that [ Soundless Voice] skill.

<< At level 16, [Soundless Voice] gives you the ability to read the thoughts of speechless monsters when you touch them. When this skill reaches lvl 50, you will be able to read their thoughts without touching them. >>

This skill, why couldn't I have gotten it sooner!?

As I tried touching the slime while activating the [Soundless Voice] skill, the Slime's thoughts suddenly flowed into my mind.

((I love you, I love you... I love the Devil... I love you...))

The Slime rubs itself against my hand. What the... It's cute? If I don't think about the naughty things it just did to me, this monster is simply too cute!

As my womb is slowly filled by the Slime's eggs, I make my way over to the Fountain of Life. Supported by the worried-looking Velke, I settled into the pool and laid the freshly produced Slime eggs.

After I produced 20 small, soft eggs, the Slime touched the eggs happily as its body changed from lemon yellow to dark yellow.

Anyway, I'm going to sleep now.
