Chapter 59 – Floor 9. Sex Appeal

Caught by the worthless slime and unable to move a muscle, reduced to a ridiculous state, I closed my eyes and endured this humiliation.

I will absolutely not surrender!

But regardless of my determination, the slime’s moist tentacle ends crept up and down the shaft of my erect penis, which was sticking out.

The slime’s tentacle, which had formed a circle by wrapping around the shaft once while caressing the testicles, as if giving a massage.

That tentacle with its springy elasticity applied pressure, briefly stroking the shaft before moving back down to knead the sack containing the testicles.

At that sensation, like being licked simultaneously by a cold hand and tongue, my half-erect penis responded as if announcing its reaction, shamelessly showing itself off by becoming even larger and stiffer.

“You fuck..! Stop! Stop!”

Squelch-?

The slime tilted its head with an expression that seemed to say it couldn’t understand me now, despite having obeyed well until now, and I tensed my entire body.

Guuuck-

But the restraining force only grew stronger in response, refusing to allow any resistance.

The sensation of my entire body, like being wedged between a water-filled sofa and an exercise ball, gradually increased in pressure until it became difficult to breathe.

“Khaaak..! O-okay! I won’t try to escape! Loosen up!!! I’m dying!!!”

Quick surrender is important.

After all, embarrassment isn’t more important than life.

Hearing my declaration of surrender, the slime seemed satisfied and returned to its previous pressure level before resuming its caresses.

I accepted the slime’s ministrations, which were leisurely building up to ejaculation, feeling as if my penis had been placed in a massage machine, accompanied by wet, sticky sounds – squelch- squelch-.

The gaze fixed on my painfully erect penis intensified.

“Don’t look at me!”

“What are those dangling things below the penis, human.”

“Those are the customer’s testicles. Humans are a species where the testicles are not hidden inside the skin but protrude outward.”

“How dangerously exposed to keep one’s vital point.”

I wanted to express admiration for the nerves of these creatures, casually discussing human design while looking at someone else’s penis, but I could only bite my lips tightly.

The slime slowly lowered its waist.

I’m not sure if “waist” is the right expression for a slime mass, but having mimicked a human form, that’s what it looked like.

With a squelching sound, the glans touched – tap – against what would be the perineum, the area between the plump, smooth thighs in the region that would correspond to a human’s groin.

Unlike just before, when I could barely stick my face out from the bulging areas mimicking breasts to breathe, the change in height meant the slime’s face was now right in front of me.

The unfamiliar face of the wizard I had never seen before.

Looking at the eyes and slender jaw, it seemed to have had quite a sharp impression, but the slime’s goofy smile completely ruined that impression.

“Y-you..!”

Squelch?

“I pulled you out of the dark, damp, dirty underground sewer and even gave you an evolution, and this is how you repay me!”

You ungrateful onahole!

Having even given it plastic surgery, only to have it try to assassinate its master through death by humiliation in this situation, I couldn’t help but be indignant.

Bubble bubble..!

The slime’s cheeks puffed up, making bubbling sounds as if upset.

“Being brave while captured and unable to move, customer.”

“Ha! I will not surrender!”

It probably wasn’t the right line for this situation, but the Suspicious Merchant didn’t seem to care, drawing closer to directly observe my penis being automatically serviced by the jelly.

They didn’t even seem to care about watching secretly anymore.

The slime, which had placed the glans against the perineum—the area commonly called the groin—rubbed its smooth surface by moving its hips back and forth.

It’s an area where there would normally be two holes to insert something into, but whether deliberately not implemented or out of ignorance, there was only the smooth, sticky surface of the slime that secreted viscous liquid.

Slap- Slap- Slap-

But the act of vigorously moving its hips and rubbing my penis against that area was clearly mimicking sex.

“Urgh..!”

The slime’s slippery skin quickly brushing against the veins, contrasting with the leisurely massage of its tentacles.

The thin pre-fluid flowing from the tip of the glans mixed with the slime’s bodily fluids.

The rising sensation of ejaculation. The penis swelling, preparing to expel semen.

Pause.

Perhaps sensing this, the slime stopped its rapidly moving hips and slowly lifted them, with only the tentacles kneading the testicles continuing to move.

Freed from the pressure that had been pressing on my chest, making me feel like I was buried under a thick blanket, I took a deep breath.

The air fully inflating my lungs felt satisfying as it swept through and then escaped outside again.

“Whew…”

The slime had stopped its vulgar movements at the threshold of maintaining the sensation of impending ejaculation.

Right in front of me was the slime’s genital area. That is, not a real one, but a smooth, golden groin corresponding to a woman’s.

‘Seems well-fed.’

The thighs and hips were plump enough to think that.

“…So what now? Not going to continue?”

Squelch-♡

Looking up at it with an expression asking why it suddenly stopped, the slime had a playful face as it slightly rotated its pelvis, adjusting its position as if targeting my penis.

And then─

Plunge─!

“You fuck..!!!”

The pile-driving motion descending at high speed.

My penis, standing straight toward the sky, penetrated the slime’s perineum, which had been smooth without any hole.

Burrrrrrr─!!!

The sensation of ejaculation reaching its limit and the powerful stimulation striking at that precise moment.

My penis, pushing through the high-viscosity fluid in an instant, fighting past the clinging gelatinous passage, finally couldn’t hold back and expelled white fluid.

White cloudy liquid shooting toward the black sphere-like nucleus of the slime. The pure slime interior, so clean it could be called refreshing, without a single impurity, was now sullied by the white foreign substance.

“Haaaaah..! Ahh…”

The reason the slime hadn’t created a vagina or anus wasn’t because of ignorance about female reproductive organs.

From the beginning, since the fixed external form used in the evolution ritual used the human female wizard’s appearance data, it could have implemented one if it wanted to.

But there was no need.

A fluid body can accept a male organ anywhere.

Even without any holes, forceful insertion will go in. In fact, in terms of stimulation, it can provide an even more intense experience.

This would be unknown information for an ordinary evolved being, but the experience of being its master’s onahole had instinctively taught it.

The method of pleasing its master was imprinted at the cellular level.

That’s why the slime showed a proud face toward its master, who was injecting the source of magical power inside it, even though it couldn’t properly speak.

“Huff, shit… Haven’t you heard that sex is an emotional communication that requires mutual consent and consideration…?”

Squelch?

Of course it hadn’t heard that.

“Haah… that was surprising…”

The slime sat in a posture that made it look like it was sitting on my thighs. But visible inside it was my firmly erect penis, still occasionally ejecting semen, squirming.

The white semen sullying the black sphere that appeared to be its nucleus.

Somehow finding it erotic, I slightly moved my hips to thrust upward against the slime’s pelvis.

Splash-

With the distinctive sound of flesh hitting the gelatinous surface, its entire body undulated.

At that vibration, the slime made an expression as if it knew what I wanted, then slowly melted down before taking shape again.

Having regained its human form, it was now in a cat-like posture. A position with its buttocks raised high toward the sky in my direction while lying prone on the floor.

With my penis still inserted between the divided buttocks, the slime wagged its bottom like a cat, as if telling me to thrust comfortably.

I wonder how it learned such things.

“…For an onahole, you’re quite lewd..!”

Though my legs were still restrained, my two arms, upper body, and waist had been freed from its constraint.

The meaning was clear: move as I wish.

Slap-! Slap-!

Indignant at this creature trying to manipulate its master according to its own will, I strongly slapped its buttocks with my palm.

With a sound like air bursting, the golden surface rippled dynamically.

“I’ll make you regret provoking me..!”

I’ll ravage you as much as you want!

***

Slap─ Slap─ Slap─

Vulgar and loud friction sounds spreading inside the burrow lit by soft light.

The source of that sound was a naked man and a golden, human-female-shaped slime beneath him.

The image of a male putting all his effort into thrusting his hips into a being not of his kind, striving to inseminate it. The two others huddled in the burrow with them were engrossed in voyeurism, not wanting to miss a single moment.

The scent of the male hung heavily in the burrow.

“Is human mating like that?”

“Normal humans avoid interspecies acts, but in the customer’s case, it’s unusual.”

Even as this brief exchange occurred, the violent friction sounds assaulted their ears.

One was a wild warrior with a desire for strong offspring, and one was a dream demon that seduced humans.

Each, before their species, was simply a female, and they unknowingly envied that lowly creature with its zealous male.

Squelch- Squelch- Squelch-

The ridiculous sounds of the gelatinous flesh persistently gripping the male organ, refusing to let go.

But neither the slime nor the man seemed to care as they continued their bestial mating.

“Ho…”

A short exclamation.

The slime doesn’t make pleasure cries. The man just breathes heavily while thrusting.

Even so, an overwhelming aura of lust pervaded the burrow, imposing a silence.

The tail of the one called the Great Warrior, who had defeated all other warriors, swept across the earthen floor, curling closer to her body.

The demon who governs dreams, once feared and distrusted by humans, slowly closed her legs.

But as if not caring about such small actions, the male organ, expelling white essence into the slime, once again sullied the slime’s nucleus.

“Huff… hah…”

Then, the man looked up at the ceiling, breathing heavily as if it was over.

Just as both of them narrowed their eyes simultaneously, about to look away pretending not to see,

“Ha! I’ll wreck you all night long!”

Bubble♡

At the man’s declaration to ravage it all night long, the golden slime, as if having received a marriage proposal, showed delight and climbed on top of the man, supporting his back like a cushion.

The male organ, standing like steel as if it were natural, and the slime’s gelatinous body starting to move again.

The man thrust his hips to match the slime’s movements for extracting semen, pistoning as if in competition.

“Human mating is long and intense…”

Knowing that mating among her own kind lasted for long periods, the Great Warrior didn’t find the man’s claim to go all night particularly questionable, but this was the first time she had seen such vigorous mating.

The Great Warrior, who hadn’t taken much interest in the ecology of other species, filled her ignorance with what wasn’t common sense.

And so time passed.

Even though it was the lower floor of the Labyrinth of Osiris where almost no sunlight entered, when it was clearly a late hour.

The ongoing intercourse had yet to end. As if truly going all night long as promised.

Splurt-

Persistent kissing.

Golden slime tentacles stroking the male organ.

Wasteful spilling of the man’s semen on the earthen floor, as if the slime had already accepted enough of it.

The wastage seemed natural because the slime’s interior was a mess.

White stains visible everywhere as if the entire body had been violated, and semen filling the cavity containing the nucleus, which seemed to mimic a womb.

It looked like semen would gush out like a flood if the belly were lightly pressed with a hand.

‘Is it finally over?’

‘Customer, is he really human?’

The two non-humans gave the human a look close to reverence.

But as if even that wasn’t enough, the man sharply slapped the slime’s buttocks, which was rubbing its belly full of semen, and took out a statue in the form of a naked woman from his bag.

“I have to fill these ones too… so troublesome.”

Squelch!

Without hesitation, as the man shoved his male organ into that, both were left speechless.

…The wet sounds filling the burrow increased.
