Analiah was sitting on the short beach in the harbor. The sun was bright and warm, and the waves were gently lapping about her. She was also chained to a large, thick post driven into the sand so deep it was anchored in the bedrock. The chains came from the top of the post, pulling her arms high above her nude body. The young woman squirmed in the water, but her ankles were also chained to boulders in the sand, forcing them open, facing the sea. Her heart raced, her eyes darted about, searching the ripples on the water in fear.

She was to please the Great Kulthu.

The village or town, depending on your preference for size, nestled beneath a large bluff that tapered down to the ocean, creating an arm that reached into the sea. It offered a natural harbor in an ocean teeming with fish. Farmland flourished behind the village with its port and fishing boats, giving the villagers an almost privileged spot. A road ran from the port, through the houses and farms and into the forest to reach the City, where traders took dried fish and brought back fancy wares.

But the village had a problem. Each year, when the moons aligned in summer and brought the highest tide, the Great Kulthu would rise from the depths. Huge arms like those of octopi would lash out from the waves, and lay waste to anything made by Man in the harbor or within reach on the shore. The Elden god was not pleased.

Ancient villagers, however, discovered that Kulthu wanted a sacrifice. A young, beautiful woman, to have his way with. And then he'd leave the village be. Even more than that, the seas would be plentiful, the weather balm, and the winds kind for the catch. Other towns, even cities with their mighty galleys, their priests and shamans, did not dare encroach on the village. Their ships would be turned away by foul tides. The village of a few thousand people had found an idyllic place in a twisted and tortured world. But, it came at a price.

Analiah was just a farm girl; The Great Kulthu did not care about social rank. No. Each year, all the women who had not yet born children were taken to the temple. It was a stone structure at the top of the bluff, where villagers rendered their cult to the Elden god who protected them. There, the most fertile, whether the daughter of the Lord Mayor or one of the scullery slaves, was selected. Even women traveling through the village could be selected.

The priestesses and all the villagers cheered and praised Analiah, telling her what an honor it was, and how grateful they were. It wasn't terrible, she was told. Most of the girls were left behind by the Great Kulthu; and they became priestesses in his temple. She would never have to work on the farm again. But she would also never be with a boy. And there was a boy she fancied, as would be expected. She hoped he wouldn't see.

Chained in the soft surf, Analiah only had a vague idea what to expect. Most villagers fled on the day, since there was always the chance Kulthu would not be pleased with the offering. Some lingered to watch, but no one in her family had ever been stupid enough to do that. She'd heard descriptions, but they often varied and contradicted each other. She really did not know what would happen, and it got her heart racing like never before.

The lapping of the small waves as the warm water surrounded her legs and hips would have been relaxing, but it only made her more anxious. Just before the Wardens chained her, the High Priestess had offered her a small, wooden cup with a shimmering pinkish liquid.

"Trust me, it helps," the older woman said softly in a confident tone. Analiah gulped it down, and let herself be chained. It wasn't any use to protest, or to cry. Though initially a few tears had escaped. But it took the water more than an hour to rise from her feet, to surround her, to eventually almost entirely cover her legs. There had been some time to come to grips with her situation,

She was flushed, and despite the water and the soft breeze, felt hot. She was incredibly aroused, and realized what the priestess had given her. The feeling conflicted in her head, as she felt light, and a little hazy. She couldn't help imagine what the Great Kuthlu looked like, how his appendages would move, and her mind reeled as she felt waves of arousal at the thought.

The water had risen enough so that the small waves ran up between her opened legs and bobbed against her clit, sending sparks radiating up her spine. She sighed, and twisted, her body squirmed with intense arousal and even more intense fear. She looked desperately into the water to see what might happen, what was coming.

Several times she'd felt things brush against her legs, or toes, and jumped as much as the chains allowed. But they were bits of seaweed, or a fish that was perhaps a little too curious for its own good bumping into her and scurrying off. She was chained, unable to escape, her legs open and her sex completely exposed to the monsters of the sea.

The waves were sometimes smaller and sometimes a little larger. One of the larger ones washed over her quivering thighs, and she could feel the sand move beneath her buttocks and legs. When the water receded, she saw a wide, stone gray but shimmering thing laying across just above her left knee. It was just as warm as the water, so she hadn't felt it. Her hair raised up on the back of neck and head as she realized she could no longer see the sand between her legs; the water looked much darker.

There was something there!

What looked like a fat arm of a starfish, but smooth and shiny flipped wetly across her other leg, also above her knee. This time she felt it. Little suckers on the underside latched onto her skin, even as she panicked, tugging at the chains, but unable to move more than an inch.

The water was now high enough to cover almost all of her pelvis, but the waves had stopped. Instead, she felt something brush against her inner thigh, soft and fleshy. First about half-way up her knee and crotch, then suddenly it bumped both sides of her legs just inches from her entrance. It was there!

Analiah tried to make out what it looked like, but it was just dark in the water. What would it do? Would it just enter her, now, like that? She hadn't even had a man in there. She was breathing raggedly, tensing for the inevitable. Something soft, smooth but hard touched the junction between her leg and publis, on both sides. Before she could make out what was going on, two dark green, thick, tentacles came out of the water, sliding over her hips and wrapping around her waist.

The tentacles were smooth, and held her firm but not too tight. That's when she noticed that her ankles and knees had already been wrapped up. But she was more worried about what might be between her legs. What felt like soft hairs were brushing all over her pubic mound, going into every crevice, teasing between her lips and going down so far as to tickle the bottom of her buttocks where they met the sand.

The young woman's mouth was open, but it wasn't a scream. Her mind reeled when she heard herself moaning. How could she be so aroused at a time like this? As her brain tried to run away in horror, her hips actually pushed forward, lifting and offering her hole to the monster. Was- was it just that she wanted to be over quickly? She still had some of her mind left to rationalize her behavior, but she was feeling hazy and really, really just wanted to give in to the warm, wet sexual pleasure.

Then there was a large splash, sea water being thrown on her upper body that was out of the water. A couple of quick successions of splashes brought her attention up from between her legs, as she was now completely wet. Analiah looked out into the little bay that was the harbor, and saw that the water was thrashing about. There were great big coils pushing the water round, thick as tree logs but moving through the water with an ease of the smallish fish. They were all around her, it seemed. The huge tentacles surged in the water on each side, and she could see them pushing out beyond the water, as if searching for something.

But it was only a second, because her attention was immediately brought back to just in front of her, as the dark creature between her legs started to slither out of the water and up her body. It was flat-ish, almost black, smooth and wet on the top. About maybe the thickness of a hand. It had legs or arms or something like that that were like starfish, with little suckers on the underside that it slapped onto her sides as it crawled up over her tummy. The sensation of little hairs scurrying over her skin went with it.

As the creature - or maybe it was just the end of one of the other tentacles, she couldn't tell - came out of the water, she noticed that it had what appeared to be two large, purplish bulbs on its back. Or top. As it moved up her body, the bulbs rose up its back. There were what looked like little antennae wiggling across her skin. Water was now poured over her, instead of splashed, keeping her and the creature/appendage wet and warm.

Eventually the thing had crawled up to be just under her breasts, with the little antennae wicking about the underside, rising up as if trying to reach her nipples. Analiah had relatively large but quite firm breasts that still bounced and jiggled as she struggled. They were further enhanced by very erect nipples, and puckered with goosebumps that now covered most of her body. She was fast losing control of her body, as the intensity of the fear mixed with arousal seemed to drown out her revulsion. She'd given up trying to understand it, and was trying instead to hold on to her sanity, as her body seemed to desperately try to convince her to let go and enjoy the best orgasm of her life. And at that moment, nothing was even touching her between the legs anymore! The thing had crawled up to latch itself around the midsection of her body, and her legs were once again open and exposing her sex to the ocean. Which now included a huge mass of writhing tentacles of different sizes.

The bulbs were just under Analiah's breasts now, and they opened. At first, they looked like deep purple flowers, but expanded to be semi-transparent cups at the end of a growing tentacle. Although she could jerk her body a bit, and cause her wet tits to jiggle and sway some, there was no way to stop the cups as they turned and landed onto her breasts. The cups were only big enough to cover about half of each breast. The ridges tightened, and Aanaliah felt a bit of suction. Her breasts shifted slightly inside the cups, with her nipples pointing to the base where the tentacle started. Then the cups expanded, becoming more translucent, sliding down to the base of her breasts before tightening around again.

The cups sent a ripple along the sides, squeezing her breasts in a rhythmic fashion, with varying intensity of suction. Her nipples were ensconced in a little bubble at the base of the cup, where the tentacle flared out. A liquid was injected around her areolae, somewhat gooey and slippery. That's when she felt something squirm out of the tentacle, like several little worms. She couldn't tell if they were their own thing or tendrils from the tentacle, but they wiggled against her sensitive skin. The ooze gave a tingling, almost prickling sensation that intensified with the worm-like things stimulating her nipples.

Waves of intense erotic pleasure washed up from her breasts, and Analiah could only be horrified at herself for feeling so aroused from such hideous things assaulting her. She clenched her teeth, trying to regain some composure. She was nearly immobilized, with warm water washing over her, and just then her first orgasm hit her. It was fast and hard, and she cried out for a second, as it shook over her.

The creature wrapped around her must have sensed it, because the soft hairs were suddenly replaced by suckers, and it clung wetly and snugly to her body. The twisting worms against her nipples slowed, to be replaced with a slow, rhythmic pulsing that matched the contractions of the cups against her breasts. The orgasm didn't do anything to satisfy her, however. If anything, she was even more intensely aroused than before.

That's when Analiah noticed that something was working its way over her pussy lips. It wasn't very big, maybe the width of a finger, flicking around searching for something. Her entrance! She looked down between her legs, but the water was agitated and there was foam on the surface. The thing wicked around her labia, but instead of going down, it searched upward until it found her clit. Then she felt it swell, and press against her, before suction pulled on her most sensitive nub. Her head fell back as she couldn't help but let out a moan. The suction started to pulse, and the tendril began to hum.

The suction on her breasts resumed intensity, and Analiah finally brought her head back up. That's when she finally saw Him. She knew what the Great Kulthu looked like from the drawings. But now she was bound against a post in the sand, her legs spread open facing it. It was both hideous and impressive, almost like a massive, deep-green purple head with tentacles springing from the front, beneath two massive green eyes. He rose slowly out of the water, something like a huge octopus, something like a much more indescribably powerful and twisted monster.

"Great Kulthu!"

The water parted and ran down his fleshy, purplish sides, with some seaweed clinging here and there. He towered above her, and she could only stare trans-like, into the deep sea green eyes. But even as she stared up in awe, the tentacles and their pulsing cups sucking at her nipples and pulling at her breasts had not stopped. The humming, pulsing on her clit grew only stronger. Once again her body betrayed her, a tortured orgasm welling up and flowing over her. As her body shivered and jerked, however, she couldn't look away from the monster, his deep green fleshy skin, the deep purple veins that ran along the tentacles that now rose around and above her.

The orgasm faded quickly, and once again she was left wholly unsatisfied. They were superficial orgasms, mere twitching of the flesh. A deep hunger had awoken in her, and the rush of eroticism only threw into relief how empty she felt. How... hollow, in desperate need to be filled. Plaintive moans escaped her as she stared up at the Elden god, praying to be filled.

The tentacles parted in front of her, and the great eyes sank to hover a few feet over her head. Beneath the deep sea orbs were rents, with wiggly flesh like curtains. Below that, the skin turned more pinkish and purple, covered in bumps and odd little protrusions. The flesh parted, revealing a lighter colored cavity that widened as it hovered over her body. It was lined with short, pinkish tentacles that writhed. There was thick, pinkish-green slime everywhere, so thick that some of it dropped in gobs.

But what got Analiah's undivided attention was the tentacle that uncurled above two large sacks that appeared to be filled with a roiling, shimmering, off-white liquid. It wasn't a tentacle, she knew for certain. It was a penis, but long, thick and wiggling. It was covered in the same goo, shimmering as it descended from the creature, towards the space between her legs. It tapered towards the end, had ridges all along its length, with what looked like small hairs waving in the slime that covered it. The end was shaped like an arrow head, triangular with three fleshy hooks. It was big, with the head about the size of her fist. Analiah's heart raced, and her mind wanted to recoil as she feared how it would fit. But her hips thrust forward eagerly, her clit being strummed relentlessly by the tentacle attached with suction.

The sea water had vanished, and now Analiah could see clearly between her open legs. She was still chained, and wrapped in that other tentacle thing that kept stimulating her breasts. Gobs of the goo fell from the monster, slick, warm, plop. On her legs and thighs.

The tentacle penis flopped down across one of her thighs, before a pulse sent it hardening and straightening, pointing towards her entrance. It moved with pulses, slithering down between her legs, and the point came to touch her glistening labia. It didn't rush, it seemed to enjoy exploring. The head rocked back and forth, exploring the length of her slit, before turning down and pressing against her pussy.

Everything was covered in slippery slimy goo, and she knew she had to relax. But she also realized she had no control of her body, and there was nothing she could do but endure. The peniscle pulsed again, pushing the arrow-like head into her. It stretched her unbelievably, and there was pain. But it was so mixed up with pleasure that the tortured scream she let out was filled with lust. The pulses started to come faster now, each pushing the monster's appendage deeper into the helpless woman.

Even when she felt full to completion, it didn't pull out. The creature wouldn't thrust in and out, but rather the tentacly penis would throb, sending all the ridges along it scraping against her insides, dragging against every possible sensitive bit of skin she had. The Elden god was taking his time in fucking her.

Analiah was being driven to levels of arousal she didn't believe possible. But, she could not cum. She writhed about in desperation, pleading. But the pulses came faster and faster at their own pace, and there was no relief.

The great green eyes watched her from above the fleshy, tencled-covered gap that hovered over Analiah. One of the worm-like appendages seemed to hang from the Elden god's intimate parts. It was smooth and ended in a bulbous clump, like a half-dozen closely packed grapes. It was covered in the same goo, and Analiah suddenly had the urge to lick it. She had no idea where it came from; her body was being ransacked for pleasure and she was on the cusp of a denied orgasm.

The bulbous clump was no more than a couple of inches from her face, so she was able to stretch the last the chains would allow so her tongue could just touch the slimy surface. It tasted sweet and salty, like honey diluted in brine, with strong sea tones.

The Elden god shifted; and she saw his eyes grow more intense. The pulsing inside her became random, and she couldn't help herself from straining forward to give the little clumpy thing another lick. The monster shuddered, and almost to her dismay, she felt the tentacle suddenly pull out of her. Before her eyes could even widen in shock, the tentacle was back, shoving into her with renewed ferocity. This time it wasn't just pulsing, it was now thrusting back and forth into her.

Analiah felt tentacles writhing on her hands for the first time. There was a clang, and suddenly her arms were free! But, instead of twisting away, she managed to lift herself to take the bulbous appendage eagerly into her mouth, savoring the salty sweetness. She wrapped her hands around the smooth stalk, gliding them back and forth, stroking it with the same rhythm the tentacle was thrusting between her legs.

It couldn't have been a moment before she felt her mouth filling with the same salty goo, the tentacle in her hand throbbing. She tried to swallow it all, but some of it leaked. It sent a warm sensation pooling in her belly, and she felt weakened. The blub on the tentacle slipped from her mouth, still dripping the ooze, and then she felt the orgasm boil over on her insides. Everything seemed to stop, the sea, the thrusts, the air... just the deep pulsing of the tentacle inside her as it flooded her insides with Elden god cum. Each pulse sent wave after wave of orgasmic pleasure, building on each other until her mind was swamped in endless bliss.

Eventually it ended, and Analiah collapsed, covered in sea and ooze and cum. But she felt an intense, comforting warmth flowing from her belly. Her god loomed above her, and something in his eyes showed satisfaction, even happiness if such a creature could experience that. The goo she had swallowed continued its effect on her, as she felt weaker, just wanting to rest. To sleep, in the warm, smooth, soft tentacles that curled around her. The light faded, and she drifted off into a new dream...
