Your boots hit the stone floor with a moist squelch. Glancing down, you grimaced, realizing the floor is covered in a thin layer of some kind of mucus. That, combined with the drab surroundings and the distant but steady drip drop plip of water told you all you need to know about this floor of the dungeon. "Great, a sewer level," you mutter as you shifted your feet trying to get your footing on the slippery floor, "Nobody likes fucking sewer levels."
Resolving to hurry through this floor on your quest downward, if for no other reason than not having to fight a million lame ass giant rats, you unsheathed your sword and hold up your torch into the dark to peer down the murky tunnel. The path seemed clear and straight forward, and blessedly clean for this type of dungeon section. Strangely clean in fact - not a bit of debris to clamber around or a face down corpse to search or any misplaced clay pots to smash open. Huh, weird. Oh well, you shrugged thinking to yourself as you set out. Who the fuck really knows how the Dungeon works anyway? Maybe whatever demented god that made this place just forgot about this corner of it.
Though initially unconcerned, the faint niggling sense of disquiet did not leave you, and it only got amplified the further you go. The floor appeared to be a maze of twisting and turning passages, but you don't find a single enemy to fight or chest to loot. Great, even better, it's a fucking maze - fortunately you've been doing this shit way too long and know how to handle this sort of nonsense by now. Sheathing your sword, you fished out a bit of chalk from your sack and start to mark the walls and corners as you go. Sure enough, through trial and error you quickly figured out where you'd been looping on yourself, and began eliminating choices. It took only maybe twenty minutes of this brute force method before you found yourself headed down a long winding tunnel you'd never seen before, moving towards a bright light you hoped was the exit.
Stepping into a large well lit chamber with a high vaulted ceiling, you blinked repeatedly in confusion at the change in your surroundings. Whereas everywhere else on this level was completely empty, here the corners and walls were heaped with treasures and trinkets, and all the bits and bobs you normally would've seen scattered throughout the floor were stacked here. Squinting incredulously, you lifted your torch in confusion. "What the fuck? Wait-" Big open space, lots of treasure, no other enemies- *shit*.
You spun around in alarm but it was too late, the gate came slamming down over the entrance you'd just come through. Of course - it was a BOSS ROOM. "Oh fucking COCK-" you swore, grabbing your sword and jerking it out of it's sheath.
"Mnhh, sounds nice...?" replied a distant feminine voice, echoing from the vaulted ceiling overhead. Backpedaling, you held up your torch and gaze at the ceiling, looking for whatever was obviously going to drop in on you from above. Sure enough, you saw a viscous pulsating mass begin to swell and spread at the ceilings highest point, it's surface cloudy and roiling. A bulb formed at it's center, and something stretched out of it, slowly taking a vaguely humanoid shape.
"Nope!" You shouted, throwing your torch at it and pulling a wand of lightning from your belt. FUCK slimes, all your homies hate slimes - you pointed the wand at the boss monster and began to slide your thumb along the sequence of activation runes. Before you were able to crack off the spell however, the floor beneath your feet surged and wobbled. You stumbled for a moment and then felt your foot get stuck in something. Looking down, you realized the layer of slime that had been all over the floor had collected beneath you and seized your leg. "Oh you dirty mother fu-" you started to snarl, jerking your wand downward.
"Too late~" came the distant voice again, taunting and singsong. With a loud squelch the mass on the ceiling launched itself down towards you at high speed. You instinctively tried to dodge roll out of the way like you do everything else but with your foot stuck fast you merely slipped and fell to your knee. Jerking your arm upwards you began to fire off the spell from your wand but it was too late, the wriggling mass hit you from above like an ocean wave slamming into the beach.
You felt the wand get knocked out of your hand - or more correctly, sucked out of your hand, and then shot across the room by the internal flexing of the slime. You could feel yourself floating, like you were in water. No, not water - foam. Or marshmallow. Something soft and puffy. Fluids contort and squirmed around you, and what felt like a million hands ran themselves all over your body. You heard a distant hum of approval vibrating through the slime engulfing you, and then downward pressure forced you to the floor. The fluids receded from your body and you could finally open your mouth after what felt like ages, gasping for air. You tried to move but found your arms and legs stuck fast to the floor at your wrists and ankles, with large pulsing gobs of slime clinging to your hands and feet. The slime receding from your body rose up, once more forming that vaguely human outline - something like a person, but with a red glowing nucleus floating in the center of it's partially see through chest.
The shape started out vague but that quickly changed. With what sounded like a soft moan, the slime person arched it's back and it's midsection swelled, two very visually accurate and very large breasts forming over it's chest. Each is capped by a dark sea-green nipple and jiggled enticingly of it's own accord as the transformation continued, with the slime's 'head' taking on further definition and becoming a sculpted simulacrum of a beautiful woman with a coy smile on her face, looking down at you with crimson eyes through long dark lashes in an amused fashion. A mane of sea-foam hair swirled about it's head, cascading down it's back, only partially merging back in to it's main body where it draped over the things shoulders. The bulging mass at the center dropped, and a slender sloping waist formed followed by a wide swell of hips tapering down into thick thighs and supple legs. What was once a mostly formless mass had turned into a highly detailed imitation of a naked and well endowed woman, looking down at you with a mocking smirk.
Placing one slightly over-sized hand on her - no, 'it' you try to remind yourself as you focused on not staring on it's bouncing breasts swaying back and forth above you like heavy pendulums. Placing one 'hand' on IT'S hip, the slime cocked it's head to the side and studied you, grin widening. "Well well well," it purred, somehow making words with voice like a human despite the fact you could see partially through it's chest, which is what you were absolutely looking at and not it's tits. "Look what we have here~"
Gritting your teeth, you tried to flex your arms and legs, attempting to escape the elastic iron grip of the goo binding you. No luck though, it just stretched slightly and then snapped back when your strength gave out. The slime snickered at your predicament, leaning forward and watching you struggle. "Aww, is the widdle human scared~?" it cooed, twisting it's shoulders back and forth making it's dangling breasts swing back and forth temptingly. Distant torchlight glinted off it's moist surface, and the things crimson core and eyes pulsed with a steady glow that hurt your eyes to stare at for too long. "Fuck you!" you hissed, cocking your jaw and spitting at the creature defiantly. You probably should have reminded yourself what you were dealing with.
An exaggeratedly big hand - almost like a paw, but with five articulated digits - came up and wiped the small bit of spittle from the things face before dropping down to wipe the moisture off on it's gelatinous chest. It moaned softly, rubbing your fluids into the 'skin' of it's breast, squeezing the massive mammary facsimiles between long fingers. The tissue certainly bulged around it's grip like the real thing, squelching wetly beneath it's palm like it was smeared with a sheen of oil. "Oh, offering that already? Well, that saves a lot of time doesn't it?" the slime asked with a knowing smirk.
It must have been able to see the incredulous confusion on your face, because it broke out into wet mocking laughter. "Ahahaha! Don't know what I'm talking about, idiot? Don't worry, I'll show you~ But first, let me just... return that little favor," it said with it's grin widening, too wide for a normal face. The slime sank down onto it's knees, straddling your hips. You could feel something very much like the weight of a woman's ass pressing down on your groin. You thought it might even be... wriggling a little, grinding supple cheeks against your codpiece. Opening up it's mouth, the slime then displayed for you it's long tendril like tongue, stretching it out at least a wriggling foot from it's lips before sucking it back inside. She - it - pursed it's lips and you could hear the wet sound of fluid gathering. Grimacing, you braced yourself for the thing to spit back in your face, clenching your eyes shut.
