The Slime Onahole's Semen-Sucking Tentacle Assault
*Schlurp— squish— squish— sluuuurp— glurk?! Gurrrgle...!*
As Han Yeoul launched his attack, thrusting the slime onahole rapidly onto his cock, the Big Slime's ego panicked and had no choice but to halt its tentacle assault. To a creature whose existence revolved solely around eating, sleeping, and surviving, this human behavior was utterly incomprehensible.
The Big Slime, which had always perceived its surroundings through vibrations, could sense the human shoving a hot, throbbing rod into it—and even see itself being used by that human. There were plenty of strange things: why had its body shrunk so small? Why had its bodily fluids changed in composition? Why wouldn't its tentacles emerge where it wanted? But instinctively, it knew one thing—the human wouldn't kill it.
The Big Slime sensed on a primal level that the human had taken it to use it. Though the human was plunging his meat rod deep inside, he wasn't tearing through its epidermis to target the core. Instead, he was rubbing against the inner layer where the coiled tentacles emerged. That rod couldn't even reach the core, and rubbing it against the epidermis did no harm at all.
On the contrary, an inexplicable pleasant sensation washed over it. A sensation it had never felt before in its life. It was as if some fundamental biological urge, essential to its very being, was being fulfilled.
Feeling that its survival was secure, another instinct of the Big Slime awakened. The instinct to eat. To devour.
*Sluuuuurp! Slurrrp— squish— sluuuurp!*
"Whoa! What the hell is this now?!"
The tentacles that had been stabbing at his cock like needles suddenly stretched out all at once, wrapping around it and beginning a peristaltic, wriggling motion that stimulated him relentlessly. The sucking force generated by the squirming tentacle pussy's undulations demanded his ejaculation.
Han Yeoul's PC muscle fought desperately to hold back the semen trying to escape.
*Gurrgle! Glurk!*
"My cock isn't food! ...Or is it?"
From the telepathic intent sent by the Big Slime's ego, he could feel both hunger and lust. The Big Slime didn't know it was lust, but Han Yeoul did. With its appetite and lust merged, the Big Slime was devouring his cock with tentacles, melting it down with acidic fluids just like prey.
Gazing at his cock inside the translucent slime onahole, being ravaged by countless tentacles, Han Yeoul let out an exclamation.
"So this is what it feels like to be eaten by a slime. Might be better than I thought...?"
Slimes were monsters composed of liquid, making cocks—mostly blood-filled sponge-like structures—extremely easy for them to handle.
*Glurk? Gurrrgle!*
The Big Slime could vividly sense the blood and fluids surging into the cock. The more it tried to digest it with its tentacles, the more fluids rushed in. Instinctively, it knew that stimulating this delicious prey would make even tastier food come out. It sensed a thick, life-force-laden liquid being produced in the fleshy pouch at the tip, building up unbearably.
Feeling the production of that life-rich fluid accelerate with every stimulation of the rod inside its tentacle hole, the Big Slime moved its tentacles faster.
*Slurrrrp— sluuuuuurp! Squish— squish— schlurp—!*
*Glurk! Glurk! Glurk!*
Hurry up and give me that thick life-force liquid! It wrapped and squeezed the cock with tentacles, milking it relentlessly. Noticing the human's sensitivity to its fluids, the Big Slime produced stronger acidic lubricant—carbonated lube—and rubbed it sloppily against the shaft with its tentacles.
"Ngh...!"
But sensing through vibrations that the human was desperately holding back the release, the Big Slime grew angry and extended one tentacle long and thin, sending it outside the hole.
Before Han Yeoul noticed, two long, slender tentacles slithered down the base of his cock and gently wrapped around his ballsack.
"Hah! W-what the—?! Hnng...!"
Startled by the sudden slippery sensation on his balls, Han Yeoul cried out. Soon, a deflating moan escaped his lips.
*Knead, knead— buuurrr—*
The tentacles enveloping his ballsack spread wide, vibrating gently like a massage while lightly squeezing. The unexpected ball stimulation sapped his strength momentarily, weakening his control. His PC muscle loosened just a bit, and a dribble of semen leaked out from what he'd been holding back.
Having successfully ambushed and extracted a bit of the thick life-force liquid the human had been clutching so tightly, the Big Slime rejoiced and sucked at the semen in the urethra, savoring it.
*Glurk...? Gurrrrgle?! Glurk!!!*
The first taste of semen was the greatest shock of the Big Slime's life. To think such a delicious food existed!! It was utterly different from the food it had instinctively consumed for growth and survival. Not just the fullness from digestion, but unknown urges it hadn't even recognized were being satisfied.
The Big Slime's simple intellect couldn't grasp what those urges were, but one emotion it could comprehend: I want more of this delicious food! I want to taste it! Feel it! Pure greed.
*Knead, knead— suuuuck! Chup-chup-chup-chup! Squelch— squelch— squelch—! Sluuuuurp—!*
"Haaah...!!"
The Big Slime mobilized every function at its disposal to stimulate the human's cock and ballsack. It vibrated each tentacle finely while maximizing its carbonated lube production. Realizing long, thin tentacles provided more precise stimulation than short, thick ones, it randomly extended and retracted them, coiling and sliding over the shaft. At the same time, it stretched two separate tentacles to stroke from the bulging base all the way to the root.
Unable to withstand the merciless tentacle assault, Han Yeoul finally lost to the building orgasm. For a final sprint, he shook the slime onahole vigorously.
"Hah, hnng! Cumming in the slime pussy...!"
*Spurt— spuuuurrr— spurt—*
*Glurk...! Gurrrr...!!!!!*
Sensing the semen coming, the tentacles actively aided the ejaculation. Han Yeoul truly felt what it was like to have his cum sucked out. The Big Slime's ego had used its tentacles to create an artificial vacuum at the tip, pulling the semen forth. Soft tentacles continued gently stimulating his ballsack and urethra throughout the climax.
"Hah... ugh... haa...!"
Was Han Yeoul using the slime onahole, or was the Big Slime using his cock? The bizarre ejaculation continued indeterminately.
The Big Slime's ego was utterly immersed in bliss. No emotion it knew could describe this feeling. Urges beyond satisfaction and fullness—ones its intellect couldn't even express—were being fulfilled. Yet it also felt a pang of regret. If it could precisely understand these sensations and urges, it would feel even better. It knew instinctively that satisfaction and fullness weren't everything.
It sensed these were things it originally lacked, but that this fluid would let it comprehend them. Now that it knew, it wanted nothing else. No other food appealed. This liquid brimming with life force... Just absorbing it made the Big Slime's entire body and core melt into a warm, sunlit comfort, its form going limp and gooey as strength ebbed away.
*Gurrgle...* Want more, but... strangely, no strength left.
At first, it thought it was just full. But despite the delicious, satisfying meal, it felt damaged, strength draining. In the wild, this would be fatal, but with the human's cock inside, it felt oddly comfortable. So the Big Slime relaxed completely.
*Shlorp—*
"Hng... haa... W-what the hell did I just create...?"
After the marathon ejaculation—or rather, semen exploitation—finally ended, Han Yeoul pulled his cock from the limp slime onahole and stared at his creation in horrified awe.
This was no mere slime or onahole.
Semen-extraction tentacle machine...!
He'd been the one exploited for semen from start to finish. Despite being the owner, the slime onahole had relentlessly sucked his cock, urging him to cum until he couldn't hold back and surrendered it all.
The carbonated tentacle pussy stimulation—something he'd never imagined, thus no resistance to—was ruthlessly overwhelming. He'd thought his [Vitality Enhancement] skill and training with Brina had toughened him up, but this slime onahole made him too scared to try again.
"...Should I even try raising this thing?"
He'd been one-sidedly drained this time. Could he handle it after it evolved to stage 2, even stronger?
"Hmm, but damn, that was intense."
He couldn't use it freely, but the stimulation was uniquely powerful.
"Feels like I break my personal record every time."
He'd suspected as much since the tentacles milked him straight from the balls, but yeah—he'd cum even more than last time. Despite his physical stats and [Vitality Enhancement] improving, his stamina felt insufficient. With two onaholes now and more to come, he pondered how to manage.
First things first: name the slime onahole.
"A name, huh. Since it's made from a slime... Slami?"
"No wonder it suddenly stopped moving. Being soft material, intense use wears it down fast."
He considered restoring durability first, but activated [Onahole Absolute Ownership] instead.
Selectable Skills: Regeneration (E), Acid Enhancement (F)
Selectable Unique Abilities: Kin Devouring (E)
He'd decided the moment he saw Slami's status window.
"Select Regeneration."
Regeneration (E)
