1954
Somewhere in the Caribbean
The expedition's boat rolled lazily upon the small swells in the ocean. The sun was bright, the water was warm. Though it was called a five man research party, in truth, it was two men and three women. Studious and proper William Brown paced around on the deck, never without his white lab coat and black pipe, letting loose great puffs as he gazed at the horizon.
Lynn, his assistant, watched him with longing from the bridge. She admired his talent, his intellect... and how untouchable he seemed. Like a married man who wasn't married. Her gaze came over to the starboard side of the bow and there she saw Thomas, the backer of the expedition. A veteran from the war and master businessman, he was as fond of money as he was of himself, tanning his muscular chest with a sunning mirror.
Next to him was shy and little Lisa, his ever dutiful girlfriend. Not gorgeous, just pretty enough, her body athletic and the swells of her breasts creating a little window of cleavage in her pink one piece swim suit. The kind of woman who would make an acceptable wife for Thomas's blue blood New England family.
On his other side was Marsha. Lynn's face reddened and her heart beat faster at the site of the curvaceous woman. Both Thomas and William insisted she come along, something about needing a non-scientific eye. Lynn could see very well why a woman with no experience and interest in marine zoology was invited along.
Giant, luscious breasts. Marsha's melons wobbled and rolled with every slight movement in her chair. Her red bikini was two sizes too small, her mountainous mounds having turned a delectable shade of bronze since their journey began. Other times she would turn back on her stomach, the pressure against her chest creating a deep and soft valley of cleavage that stole everyone's eyes, even Lynn's.
And when she was on her stomach, her sculpted bottom was up. Lynn fumed as Thomas turned his head and ogled Marsha's thick and peachy cheeks. It was then the ship's radar began to ping. Lynn sighed with relief and rushed out of the bridge.
"Dr. Brown!" she called. "We've hit another location!"
William's head turned at her voice and his face brightened at the news. "Excellent! Well done. Anchor here and we'll get started!"
Thomas yawned and finally turned his eyes away from Marsha's protruding bubble butt. "Another location, doctor? This constant... sail and go... is so old hat. The diving has lost it's enchantment."
William stepped toward his benefactor, his shadow falling Marsha's voluptuous body. "It must be done, Thomas. There are only thirteen known sea caves where the so called golden octopi were said to have lived. This is the tenth."
Marsha turned her head over and removed her sunglasses. "You know, if Tom doesn't want to do it, I wouldn't mind." Her voice was breathy and soft, and when she turned over on her back and revealed once more the heavy, jiggling slopes of her tits... both men were charmed. Whatever words next flowed from those dewy red lips would be as gold, as if they came from Socrates himself. "I've always wanted to be in the water. It's so... wet."
William put his hand under his chin and furrowed his brow, thinking the young woman's wishes over.
Thomas laughed a hearty laugh. "Darling! You worry your pretty little head too much. Oxygen tanks are heavy, flippers are uncomfortable-"
"No I think she should go." said Lynn, the bookish woman unnoticed as ever. "The water here is shallow. We're close to a small island, and there's a big reef right below. It would be hard to get lost."
Thomas looked to Lisa. "And you?" He poked her in the side. "What do you think?"
Lisa gave the most earnest smile she could. "Whatever makes you most happy, honey."
"A woman after my own heart! Very well." Thomas folded his hands and then put them under his chin like William. "There's probably nothing down there... so why the hell not! More time to work on this tan..."
Marsha made a sound that was a cross between a sigh and a moan of joy.
Lynn hoped it was the last time she saw the woman alive.

Marsha swam the Caribbean depths like a complete natural. Wearing nothing but an Aqualung and her swimsuit from before, she was enchanted by the bright yellow fish, the crimson darters and the golden azure tones of puttering angel fish.
What took her attention even more was how her large breasts shook and wobbled underwater, her ample flesh swaying like the ocean itself. She wished she had a mirror, to better see her long honey blonde locks flowing through the water.
Still, she was dimly aware that the men wanted her to have more than just fun. They wanted her to investigate a cave. The place was easy enough to find. It gave off a dim, sea green glow and entire schools of fish split off whenever they came close to the entrance.
They had never mentioned that.
But they were scientists. Or at least one was. And scientists knew what they were doing.
She swam through the cave entrance and immediately felt the pressure intensify around her. Faint tingles ran along her taut stomach and around her thighs. The nipples atop her juicy breasts came to hard points. She moaned involuntarily and a deluge of bubbles spewed out of her respirator.
The resistance of each stroke seemed to lessen, as if she was being drawn or pushed forward. All around, neon sea anenomes glowed more intense whenever she passed them by. They lighted the way forward in the rocky darkness, until at last the water pushed her up.
She felt various wet things slide around her limbs. Her skin was so sensitive that they didn't feel repulsive at all, but warm and pleasant, especially as the stuff slithered between her round ass cheeks.
As sudden as the rise was, it was over. She felt the air kiss her skin and heard the sharp hiss of her equipment. All the while the surface water lapped at her huge tits like a warm tongue.
Marsha pulled the entangling seaweed off her busty form, stumbling onto the rocky shore of the underwater cave. All was dark... but for the amber and green glow that shone across the moist, craggy walls.
There was something relaxing about that glow... something compelling. Her sense of alertness, from almost being drowned among the weeds, dulled, her adrenaline rush faded. She followed the welcoming hues, her eyes wide and dilated, her dewy lips caught half-open as wonder and obedience rose through her mind.
She squeezed through the hard ravine and came upon the light source. It was perfectly spherical, like a fish egg, its strange hues brighter than ever. She stumbled forward, licking her lips, breath heavy, her full bosom heaving. The closer she came to the sphere, the more it began to pulse, the light within swirling with amniotic fluid.
Marsha kneeled down before the thing and ran a hand across its slimy surface and sighed, infatuated with the strange feel of its smooth bumps and how her fingers glided across them. Her face, lit in tones of green and gold, came within kissing distance of the egg, drawn by the whorls and clouding of glowing liquid inside.
The movement within stopped... and a hiss resounded. The upper half of the egg exploded in a spray of luminescent gold water.
Marsha's head was thrown back as something pink and fleshy latched onto her forehead. She moaned and fell onto her back. The pink thing was connected by a cord, and down the cord pumped bright and vivid emerald fluids. Marsha's fingers gripped into the dirt, her mouth falling slack and her eyes whiting out as the stuff was pumped into her brain.
Her mind was rendered blank, her consciousness suppressed.
She was perfectly ripe and helpless for what was to happen next. Out of the egg slithered a two headed snake, making its way for her twitching legs. Its smooth body caressed her thighs and passed along the beach babe's flat belly, eliciting a gasp from her quivering lips.
Marsha felt it twist between the sweet round mounds of her breasts and wrap around the back of her neck and come around, its forked tongues sliding in and out around her cleavage. She moaned, sensing its weight and touch within her delirium, not knowing the creature behind it all.
Both of the snake heads opened their maws wide, their fangs dripping with the most insidious venom... venom that did not kill... but
changed
.
Marsha screamed in surprise as both snake heads sank their fangs into her nipples, tearing through her bikini and into the soft flesh beneath. Both heads wiggled back and forth atop her supple white globes, hissing maliciously as their fangs pumped strange venom into her being.
The woman's momentary pain subsided as blinding arousal flashed across her heavy tits and sent her pussy into spasms. Her moans turned crazed and manic, screaming her pleasure so loud it hurt her throat... but still she continued on.
The serpent tightened its grip around her neck, holding on as its twin heads feasted on her fleshy and luscious tits, jiggling with every convulsion. Bulges traveled down the snake's necks as they pumped their foreign nectar into her breasts, the muted pulsing sensation driving Marsha insane, like a constant throb within her melons.
Beneath the orgasmic joy, however, more sinister things worked. Marsha was being changed, her humanity subsumed by a prehistoric species that had patiently waited for countless millennia. It was a fluke that brought about their extinction, it was a fluke that Marsha would bring their salvation.
Her skin slowly darkened yet softened, her glassy eyes and lids changing, deepening into her head. Some deep and primal part in her realized that this was the end... and that it was far too late to do anything about. That part relished the inevitable... her very species erased by something superior.
For the next hour, the cave was loud with Marsha's wails of pleasure, the last sounds she would ever make as a human...

Marsha opened her eyes. They were the same blue as before, but the pupils... the pupils were cruel, serpentine slits. She tried to move her legs, but they felt thicker and no longer separate. A hiss of joy seeped from her lush lips, seeing the coiled tail her lower half had become. Soft, alabaster scales led up into her colossal and pouting tits, her overflowing feminine mounds had the shade of fresh cream, her nipples even paler.
No sooner had her realization of her changed self emerged, than she was overcome by a deep and abiding sense of procreation. Venom drooled from her fanged mouth at the mere thought of converting the others on board the ship. Her pussy clenched and moistened over visions of betraying the remaining humans into the laps of her masters.
