An Alien Possession

It was a hot day on the isolated beach in Vietnam. The sun was beating down on the hot sands of the warm beach. Large columns of rock with heavy greenery coating them sprout out of the cool water, breaking up the smooth surface with pillars of grey and green. The sand that acts as a border between the sea and land is a delicious mixture of cool shade and burning hot where the sun was touching down. There isn't even a single piece of rubbish across the whole expanse of the closed off beach, attributed to its isolation from the rest of the world thanks to two large walls of rock that close off the sea surrounding the area and the thick canopy of lush jungle inland that prevents any non-amphibious approach. The only way into the isolated paradise was through a gash in the wall of rock that runs from the very top all the way down to the sea floor more than 50 feet down and 10 feet below the waterline at low tide. The only sign of humans ever being present was a single, small and quite rotten wooden jetty for very small craft and an equally rotten old Vietnamese cabin.

The only sound that interrupted the perfect quiet and natural sounds from the jungle was the dull roar of an outboard engine as a small craft slips through the large crack and steers to the right of the lagoon and sputters to a stop at the jetty. The only person on the vessel steps off and grabs a bulky red backpack with a smile on her face as she looks around the beach they'd just landed on.
"This place is fucking gorgeous! It's gonna look so good on my Chatsnap!"

The woman who strolls down the jetty is tan, her skin a dark copper, and has two tails of blonde hair that hang down to her shoulders. A pair of blue lensed and white framed glasses rest on her nose and over her chocolate brown eyes. She hums softly along with her music being blared into her ears by a pair of black and gold over-ear headphones, connected to the pink gold phone in her left hand as she grabs a bundle of green fabric with a long metal pole sticking out of it with her other hand. Already she's taking photos on said phone with her free hand, snapping away at the natural paradise she'd intruded on. On her feet she's wearing a pair of blue flip-flops that make a small "PAF" when they hit the sand. Her body this thick and curvy, every step making her entire form jiggle slightly. A bit of belly hangs ever so slightly down over the band holding up her black bikini bottom. Her top struggles to contain her large, ripe chest straining to hold back the beautiful orbs.

Megyn chuckles softly as she finds a good spot in the sun and starts to unpack her bag. She lays a red and black towel down on the sand and puts up the ugly green parasol that she was holding in her hand that wasn't occupied by the phone. After two more trips, she brings a second bag, a small foldup tent and a bulky cooler of bottles that rattle loudly as she places it down in the sand.
Without a care in the world, she lounges in the sun with a book, drinking icy beers and soft drinks from the cooler for hours as the sun slowly moves through the sky as the hours tick on. Eventually Megyn seems to grow restless and stands up from her prone position, putting her book down after folding the corner to mark her place. With a smile, she kicks off her flip-flops, puts down her headphones and sunglasses dashing over the scolding sand and into the cool water of the lagoon.

She ducks and dives, cooling herself down as she does so. Eventually she spots something on the sandy floor of the pool of water and dives down deeper to investigate it. Megyn approaches the shape and starts to examine it; it looks like a barrel and has a smooth, black exterior that has a squared pattern lined with grey across its hull. One end is a rounded cone with what appear to be scorch marks on it and is embedded deeply into the sand, leaving the rest to jut off the seabed at an awkward angle. The other has several small cones sticking out of it that are all hollow with damage that reminds Megyn of an exhaust. Then Megyn sees something that makes her start to violently thrash to reach the surface: a section of the hull had come out of the rest and had slid out along the surface like a sliding door. A bulbous head of a wormlike creature stuck out and spotted Megyn immediately.

It quickly chased after her, coiling its body and swishing it behind itself to propel it through the water at a surprising speed. Megyn broke the surface and started swimming hard, not able or wanting to look behind her in fear of what she'd see. The water foams behind her as the smooth, black, eel-like creature rises out of the water before plunging down in a semi-circle form, doing this again and again, making a series of arcs that periodically enter and rise from the water. Megyn works hard, desperately ploughing through the water to the shore, her chunky hips powering her forward, but the creature was catching up.

"G-Gotta get to shore! Gotta get to shore! Gotta get t-to shore!" Megyn half grunted, half wailed in fear as she felt the water get shallow enough to stand. Safety was mere steps away...

Her feet hit sand as she stands up once she reaches the shallows and she quickly trudges to the safety of the sand. But just before she reaches it, she feels something coil around her ankles and trip her up. She manages to catch a glimpse of the thick black coil before she crashes down into the water. Megyn tried to scream as she clawed at the sand to pull herself the last meter or so but found the wet sand was impossible to grip. She could feel the creatures head prodding at her ass as if it were searching for something.
An entry.

"No!"

With a scream from Megyn, the serpentine creature found what it was looking for and rammed hard against Megyn's black swimsuit only to be halted twice before it gives up that approach. It then shoves its head between her meaty thighs and the tight, black latex wrapped around them. It starts to shove its way deeper into her crack, parting the cheeks until it reaches her asshole. With a delighted squirm at this new species easily accessed entry way, it slid into her and kept going until its entire slimy length were inside her. Halfway through this process, Megyn stood up and started limping towards the shore with the long tail of the creature half-way up her ass, squirming to wriggle deeper inside.

"S-Shore... get... to... Shore..." Megyn stammered as she felt the creature wriggling through her body, making her twitch in unnatural ways as it started to poke and prod at the tip of her spinal column. Finally she felt her feet hit the dry sand, leaving wet footprints as she stumbled forward in the safe haven she tried to think she was in. Megyn jerked one last time as the creature tapped into her nervous system and took control away from her brain.

It felt like she was paralysed, but she could feel every little movement her body was making as it slowly and clumsily rose from the sandy ground and proceeded to grab handfuls of her huge tits as a twisted smile spread over her face. Megyn could feel her mind being pushed back, still present and watching everything but unable to command anything in her body to move at all.
With a sickening giggle, the creature's bulge on her back seems to sink into her as it repositions itself below her skin as it forces her body to continue groping herself. Soon it grows bored of mere groping and plops itself down onto the already set up towel and wriggles its way out of the latex thong before tossing it aside.

"oH yEs... THiS wIlL WorK nICelY..." 'Megyn' grunts happily, her voice slightly gurgled and distorted much like how a baby who was just learning to speak would sound, as her hands start to kneed at its crotch. Before it can go further with its crotch, the creature cranes it's neck over to examine its stolen behind. Soft, brown skin is perfectly spread over a wonderfully pert ass made of two large and round pillowy cushions of flesh that sag slightly due to the size. The black latex bikini bottom is pulled tight over the ass, the "Y" shape of the band that holds them up appearing suddenly from between the twin hills of perfection. There isn't even a hint of sag on the blemishless surface and the only creases start where the ass meets thigh. Finally satisfied by its examination of the rear, it turns back to its crotch. A single finger slipped between her warm, wet folds and starts to slide in and out, trial and error showing the creature what makes its new body feel good. With one hand thrusting its fingers into its crotch and the other kneading at its stolen, tanned melons, the creature started to moan quietly at first but slowly getting louder and louder as its pleasure rises like a fire burning in its groin and spreading through its veins like a wildfire. Soon the animalistic assault on its crotch gave way to results and it found its host spraying some hot, sticky white fluids down her copper thighs and onto the towel. With a curious mind, the creature scoops some up on its fingers and, to the horror of Megyn, licks it off its fingers after getting a wiff of the wonderfully sweet juices. Going back for more, the creature hungrily slurped up its own juices as if it were starved for days. Soon, her thighs were bare and the desire the creature had felt faded.

After looking around briefly, it catches sight of the small boat that had carried the creature's new vessel and its prior owner to this place and slowly walks over to it. After gathering the object that had been littered around the beach, the creature slowly began to work out how to start the engine and quickly did so. The roar of the engine returned to the Lagoon and slowly vanished as 'Megyn' steered her craft out of the rocky enclosure and towards the distant signs of a larger populace it had sighted on its decent more than fifty years before. It was a scout and it had a job to do...
