Tail of Abyss

Few adventurers are willing to venture into the waters beyond Alla’s territory. The old maps simply call it the Abyss...no landmarks, no islands, just an endless stretch of black water that seems to swallow every bit of light that touches its surface.
You were never supposed to come this far. By the time you realize it, the shore has already disappeared into the fog behind you. The water around your boots feels strangely warm, and way thicker than seawater has any right to be. Every step takes effort, your feet pulling free with a soft, wet squelch. Then something slick curls around your ankle. Slime. Thick, dark blue slime, faintly glowing beneath the surface. You crouch down and reach out to touch it. Bad idea.
...
Something long and slender slips between your legs and disappears into the darkness before you can even see where it ends. A second shape brushes against your calf almost right away, but this one takes its time, moving slowly... almost deliberately. You freeze. The first “tail” comes back, curling loosely around your ankle as the other starts creeping higher. Neither of them tightens—not yet. They just circle you, their bodies covered in warm, slippery slime, twisting around each other and sliding together with soft, sticky schlicks, like they’re feeling you out, trying to figure out exactly what just wandered into their waters.
You try to pull away. The coils tighten instantly. Something wet shifts beneath the black water with a heavy squelch. Then another. And another. Soon, those same slick sounds are coming from all around you—way too many to belong to the few tails already wrapped around your body. That’s when it hits you why none of the old adventurers’ records ever describe the creature that lives here. No one has ever seen enough of it to know what the hell it actually is. The glowing blue slime keeps spreading across the water as one tail slowly wraps around another, their slick bodies sliding together before peeling apart again with a wet schlick, leaving long, sticky strings of slime stretched between them.
Maybe they’re curious... but they’re getting bolder. One slick tendril slides slowly along your waist, writhing against you before slipping between your legs and brushing teasingly along your inner thighs. At the same time, several others curl around your wrists and legs, wrapping tighter and tighter until they lift you straight out of the water like you weigh nothing at all. Thick strands of slime stretch from your body before snapping and dripping back into the Abyss below—plip... plip... plip.
A tentacle covered in soft suckers rises toward your face. Its slippery tip presses between your lips and pushes into your mouth, slowly writhing farther toward the back of your throat with each wet slurp. Clearly, it can’t wait to go deeper... and whatever’s lurking underneath you isn’t about to leave the rest of your body alone either. Another thick tentacle slips between your legs, warm and absolutely drenched in slime. It teases you for a moment before pushing its way inside. Those slow, curious movements don’t stay gentle for long. Soon it’s fucking into you harder, settling into a steady rhythm with every wet, filthy schlick... schlick... schlick.
The tentacles around your arms and legs squeeze tighter with every thrust, and all that pressure has your cock rock hard, already desperate to cum. Another slick tendril curls around your shaft and starts sliding up and down, stroking you in long, slippery motions. It doesn’t take long before cum starts leaking from the tip. The tentacles seem almost excited by it, greedily smearing themselves through the mess and using it to make every stroke even slicker as they pick up the pace. Another spurt spills out... then another. By now, your head is completely swimming. You can barely think straight, let alone tell which sensation is hitting you harder—the thick fullness in your mouth or the pleasure building nonstop between your legs. It all crashes over you at once, your thoughts melting away into the hot, sticky mess surrounding you until you finally lose it, your whole body shaking as wave after wave of orgasm rolls through you.
Then, without warning, something hot and wet floods your mouth and spills straight down your throat. It feels like forever before the tentacle finally starts pulling back, slowly slipping past your lips with one last sloppy slurp. The final sucker hangs on for just a second longer before letting go with a sharp little pop, leaving a streak of sweet, warm fluid at the corner of your mouth. It hangs there for a moment before slowly dripping down your chin.
