The knight idly twirled her sword as she walked through the floor, mapping things out as she hit the ends of rooms. Things were going well, just as expected - the few enemies couldn’t stand against her. They just rushed her, and then they were split in two! Easy-peasy. She’d been right, and she’d rub the loot in her party’s face! She whistled happily as she made camp, and roasted some meat to have for dinner.

She figured they’d be beginning to notice she was gone, about now. They’d said they would “rest for tomorrow”, since going into the labyrinth was exhausting. Well, she’d been mapping for a bit now - the map must be nearly done, she was running out of paper. She’d be back before dawn, and then the party would yell at her but congratulate her for clearing the dungeon all on her own!

Irene and her party had been adventuring in a low tier dungeon, gathering some resources to make health potions. They had more than enough cash to buy out the shop, but the party lead - cautious both in combat and in finance - had insisted that they save money by gathering the resources themselves. The slime gel that came from the low level enemies of the mines was acidic, but when treated by the proper herbs had healing properties.

They’d been clearing it out for the tenth time when the barbarian swung his hammer a bit too much, and splattered a slime against a wall. And the wall had given way, to a steep staircase heading downwards, untouched for who knew how long.

Irene had argued that they head down - they were in a dungeon so easy that half the adventurer’s guild took it on first, what could it’s secret area hold that would threaten them? But the party leader had insisted that they return to the inn and rest. Irene, for her part, had no interest in waiting around to let credit for the discovery go to some no name wandering in on Baby’s First Quest! So she’d gathered up her gear and marched down into the dungeon to clear it herself.

Her pointed Elf ears twitched as she heard a sound - giggling? Was a monster planning to ambush her while she cooked? Hah! Don’t try that on an Elf, it doesn’t work! She jumped to her feet and drew her sword in a single movement…

And was utterly stunned by what she saw behind her. The monster didn’t even seem to be aiming to attack her. No, no - it was focused on another monster - a troll, that looked really intimidating but wasn’t a real threat, and had… need of more coverage downstairs than a loincloth. She’d never seen monsters attack each other. Least of all like this.

The assailant was pink, that was the first thing she noticed. Startlingly pink. It seemed an amorphous blob, spreading over its opponent like molasses. The monster was also utterly dominating the giant - and taking it’s length inside of it!? Did monsters even mate? But that was what it was doing. Irene prepared her blade for battle, and that was when it took it to the next stage, and Irene was so shocked she froze.

The giant made… Well, that was certainly a face. White liquid spurted into the pink, semi-transparent blob - she’d just call it a slime, even though it was far, far bigger than any she’d seen. As it did, the slime seemed to enter into the giant’s head… and it began to *dissolve*, losing its form, being changed into more slime. Within a couple minutes, the slime was alone. And bigger. It… grew, taking a humanoid shape with semi-distinct features, that of a woman with an impressive figure. And then it looked at her, grinned, and giggled.

Irene blinked in surprise and confusion. It was just a slime, it shouldn't have been able to do something so human... and it shouldn't be a threat. She raised her sword and charged the slime down. But her hesitation, her morbid fascination, cost her - the slime was expecting her and had time to act, and it was faster to do so.

As Irene barreled towards the slime, it pounced. The pink slime lay atop her, more than strong enough to ignore Irene’s struggles - it was larger than she was and had a monstrous strength far above it’s weight class. It laughed as Irene struggled and tried to throw it off, only to further embed her hands inside of it’s mass.

Irene felt cold fear as the slime regarded her, as if pondering what to do with her - her sword was knocked aside. She tried to push against the slime, but found her hands and arms simply sinking into it. She was trapped - but wait, was that it's core? A small purple orb of solidity in the gelatinous mass floated just out of reach. She might be able to-

As Irene grabbed the core the slime reacted… differently than expected. It moaned, a uniquely human moan, in fact. And then, it gave Irene a sultry smirk - she’d not hurt it, just gotten it ready to go.

The slime rippled and lost its shape, spreading, covering the overconfident knight’s body in it’s pink material - and then, there was a light sizzling sound as it melted away Irene’s clothing to get to the struggling girl’s body. The plate armor she wore burned away, sloughing off of her in a soupy liquid. Underwear stood in the slime’s way, so that went too - Irene was now utterly naked and utterly vulnerable.

Irene regretted basically everything right then. Not listening to her leader and party, not being more careful, not bringing a teleport item - lots of things. Most of what she felt was fear but as the slime made contact with her skin she felt something quite different. Not burning but… arousal? What?

Indeed, the slime wasn't dissolving Irene. No, the slime had different plans for this cutie. The slime started to manipulate the gel around her mammaries, pressing down on them from all sides, squeezing hard.

Irene was justifiably surprised - and more so when it started gently rubbing her chest, and tugging at her nipples. “W-w-what!?” She cried as the slime creature messed with her tits, the touch causing more of that involuntary arousal, making her womanhood wet with her own fluids. She had to call for help, even if another monster came they'd probably hit the slime first and she'd be able to run. She opened her mouth again-

And in went the slime, entering her mouth and strangling the scream in her throat. As the tendrils continued to grope and suck her boobs, the slime turned the parts in Irene’s mouth porous so she could breath - through a magical, and very effective filter.

Irene’s fear dulled, and her arousal only grew in strength. Why resist? It felt so good. So, so good... She moaned with pleasure into the tendril in her mouth, beginning to suck on it. It tasted sweeter than the nectar of the gods to her addled brain, and she sucked harder. As she did, she felt the slime continue to spread across her skin, engulfing her entirely.

The slime started the next step, diffusing itself into the Elf’s skin through the pores and entering into her bloodstream. And every part of her that gained slime, felt incredible pleasure, as her body grew as sensitive as her bust. Soon she was a mess of sensitivity and arousal, desperately seeking more pleasure in the pink slime that had not yet entered the part most in need of filling.

Irene had essentially been broken by the magically enhanced pleasure. Even had it left now, all she would want is to submit, to give herself up to pleasure. She’d go find a giant and make it bend her over, or go back to the first floor and jump the first newbie adventurer she saw. But that would be unnecesary, given the slime wasn’t letting go. Her body was on fire, she was practically in heat - the only thought in her mind was the words fuck me on loop, and she bucked against the slime hard, trying to make it enter her wet pussy - maybe if she grasped the core it would do more, it'd liked that. So she grabbed at it, and rubbed it-

This had exactly the effect she’d hoped for. The slime slipped into her exposed labia, spread around as Irene bucked and moaned - it was so close, so close - a small trendil formed a ring around her clitoris, and off she went into a giant orgasm. It wasn’t just the pleasuring of her clit, it was all the sensation, the situation - she came hard and for quite a while, the juices of her vagina mingling with the slime.

The slime didn’t wait around to continue - no, this was too much fun. It formed the slime into a phallic tentacle and plunged it deep inside of Irene, spearing the Elf on it. Irene screamed in pleasure once more - before the tentacle started plunging in and out and in and out of her drenched cunt, giving her more and more pleasure. She needed this, she needed it! She had to be fucked senseless! She tried to clench down on it, as best she could, keeping it in there - and finally it did, staying inside her. It felt so right to be filled - and then it started to melt into her.

Irene’s blood had, at this point, been roughly 20% replaced with slime. As Irene came and clenched and jerked, bucking against the slime tentacle and otherwise behaving like the slut she had become, the creature moved to continue the process. The slime in the Elf’s vagina melted into her inner walls, more directly replacing her fluids with goo - it pushed, right against Irene’s cervix - almost there, Irene just needed to cum once more.

The Elf slut was certainly eager to comply, as the slime pressed against her and the whole thing started buzzing. She’d just came, and such pleasure was put against her, the slime enveloping her. She screamed as she came, spreading her legs and cumming within the slime - and that, that was it for her.

The slime withdrew from her orifices, leaving Irene whimpering as she was left empty and not-being-fucked. But this lack of intercourse going to be quickly remedied. The slime tentacles slammed back into her, going deep and hard - the one shooting down her throat going even deeper, Irene ecstatically choking on the slime (although she could breath through it). Some slime shooting up her ass, and finally the slime tentacle on her groin smashed it’s way through her cervix and came to rest against the walls of her womb. The Elf was completely spit-roasted on the slime and loving every moment of it. And then, the slime came, shooting her up with fluids.

Irene shrieked her earth shattering orgasm out, flailing in pleasure and moaning as her mind cracked, and shattered beneath the wall of sensation. Nothing mattered but pleasure, nothing mattered but the sex, not even the guild. Irene was gone, and the Elf was gone. Only the ecstasy remained.

This was no ordinary Slime. No, this was a Slime Queen, capable of propagating the species. To monsters, it would simply absorb them into its mass and eventually divide. Not so with the sapient races. No, it could turn them into new slimes, new beings capable of reproducing the species. And Irene was no exception. As her blood passed 50% slime, the Slime Queen was able to complete her conversion by providing it’s own fluids.

The slime inside of Irene began to serve its second purpose. The former adventurer’s body rippled and shifted as the slime within started to melt her from the inside out. It was not a painful experience, and with so much slime in her it wasn’t lethal - instead, it was pure pleasure to dissolve, to melt into the same pink that was surrounding her. Her brain went first, the soupy liquid drooling out of her mouth as her mind went blank. Then the rest of her body gained the consistency of jello as it was melted into yet more pink.

For some time - the Slime Queen didn’t care how long, and Irene certainly couldn’t tell anymore - that was the end of it. More mass in the Queen as it went around it’s business, Irene nothing but a vague horny presence in the back of it’s mind. But that began to change - The slush that had been her brain gathered, and hardened into a smooth purple ball. A new slime core.

Over the course of hours, more and more slime gathered around the core, until it split off from the Slime Queen. For some time it lurched about the floor, as if confused, until it began to take shape. A familiar, pointy eared shape, albeit significantly more translucent and pink.

The new slime giggled, as color returned to it. It formed several protrusions from the slime, and hardened them, as they gained color as well. Irene had become a mimic slime, and was now remaking a facsimile of her armor. Soon, she looked just like the Elf that had entered the dungeon so full of confidence.

Muttering to herself as she relearned how to speak, she left the dungeon, prepared to lure her friends to her beloved new Mother...
