Blood in the Water (Ellen Joe/Shylily/Meg Multi TG)

Resting on the coast of your own private island was its own kind of peak, Markus savoring the sensation after eyeing it from afar a few years back. It had taken a lot of bribes and some threats to the surrounding locals calling it cursed or some stupid crap like that, but now he could enjoy stretches of ocean as blue and pure as a postcard. He wasn’t sure yet how to sell it to the public yet, the options to keep it as a private villa for friends or making it a full resort equally tempting. Better yet due to its spot between varying territories it avoided a lot of the legal red tape and inspections you’d normally need to take.

It was as serene a spot as you could ask for as he waded into the sunny waters, a cool breeze gently swaying the palm trees, the water so warm it almost felt heated from days of scorching sunshine. To Markus it was like heaven as he closed his eyes and floated back… Which made the shock of jaws clenching on his arm even more pronounced.

“WHAT THE FUCK WHAT THE F-HUUUUUUCK~?”

It had latched onto suddenly, Markus confused when the pain flared into pleasure, the teeth digging in as he stared into the glowing pink eye of some kind of bizarre, half-formed shark. Its teeth were gnashing, yet rather than the bloody mess that should have caused, a different fluid was splattering in the water as he came, something hot pumping from the shark inside him as full body shudders sent him toppling into the sand. He could feel it in his head, the shark’s desires hungry, his sandy locks bursting out red as his irises crimsoned. Looking down at his own erection had him drooling as the grey and white blob grew larger.

“AHhhh th-this isn’t haaaahhppening I d-hoooon’t uhhhnder- NNGH!”

He managed to thrash out of the water, his entire body pulsating as mass was sucked into the growing shark form, everything turning slimmer, rounder, his face softening as with each tug on his hair it felt like his brain was trying to suck out. The gills were struggling on land, the shark thing struggling to pull him into the water as Markus refused to let it have its way with him. He slammed it against the sand twice, squealing as something flowed back, puddling under his nipples as they expanded, his cock continuing to unload amidst the horror as each resistant thud forced his chest to burgeon, his ass perking as a jiggly pair of breasts slapped against the sand.

It really was like fighting a part of himself, the pain the only thing keeping him grounded, the weakening breaths from the sharklike thing on his arm accompanying more of his thoughts winning out on what had meant to be a parasite latching on. Weakening didn’t mean it had given up though, its flailing conjoined body and fins slicing at him, cutting an X into a thigh, the wriggling mass beginning to detach as Markus gripped with his chewed arm till the raised fist detached from the sticky innards. One final punch made the thing deflate, but not before filling and splattering him with pink, chummy material, his arm a mess as it pulled out, detached skin covered in shark guts and wriggling fluids as he rolled further up the shore.

“MMMGH ahhh fuck what’d it doooo? Ahhhn m-my cock’s UHHHHHNGH~!”

He still hadn’t had time to become aware of his new tits, but there was no ignoring the sudden pull as his spine arched, pleased screams accompanying each eruption as his cock receded, sucking in a few visceral thrusts till the whole thing inverted, his thighs clamping together in time to feel their flesh soften and fatten up, squeezing a bulging pair of labia as the new girl’s body spasmed till the parasitizing fluids had run their course. She had lost her cock but at least kept her mind, enough of the intentions still swimming in her dizzy self as she realized that maybe those locals and inspections were important for a reason.

“I-Is it like magic or some crap? Mmgh ahhh no don’t ride up like thaaaht~!”

Her swim trunks were sliding up, turned into a skintight onesie as they rode up her front, straps and metal clamping along her curvaceous legs as she moaned. At least it had acted like a blood clotter, her torn up arm gaining ribbons of scarred flesh, her left thigh’s X quickly healing over to just a sick scar as she stumbled slowly to her unsteady feet.

“M-Maybe I should put up some warning signs instead…”

She owned the land now, and wouldn’t be able to go back like this. At least she was rich so she’d be able to figure something out in isolation though the last thing she needed were a bunch of people poking around and becoming hosts for some kind of shark god things. Surely no one would be stupid enough to ignore fifty warning signs right?

“SPRIIIIIIIING BREEEEEEEAAAAAK!!!”

“Shut the fuck up Sam, we’re not supposed to do this!”

Few forces could restrain the unthinking bullheadedness of drunk college students on Spring Break, especially rich ones who could afford an international trip. The five vacationers were in various states of intoxication, Ethan starting to regret humoring this excursion as he ferried their drunkest member. Gary was a well known playboy, the business major always a braggart and excitable partier. Right now he was incoherently gurgling on top of a pool float. Ethan was the one dragging him over, regretting his maturity sometimes as the general glue that held their awkward group together. He did the plans, the bothers to get people on the same page and when no one else wanted to drag their aspirational alcoholic friend, it was clear they all just expected him to step up.

“L-Listen Sam this area is supposed to be weird and that rich guy went missing right off the coast here. We don’t want to alert-“

“HELLLOOOOOOOO! See? No one’s here. I’m telling you he’s just doing an extended vacation somewhere. I bet he made up that bullshit to keep this sick spot to himself.”

Danny was an IT major, the kind of stunted shrimp who always got carded. Ethan let him continue arguing with the boisterous loudmouth, more concerned by the fifty “Warning, Shark” signs littering the otherwise scenic spot. He turned to Caleb, the guy who had recommended this diversion in the first place, second thoughts creeping in.

“You sure this is safe? I mean all these signs-“

“Sharks barely attack anyone, that’s just an urban legend. These waters don’t have any of the really aggressive ones and besides, water’s so clear you’d be able to see one swimming from a mile away. I’m with Sam, it’s probably to scare off the tourists or trespassers.”

Sharks were one of the few things that got Caleb to talk more than a few mumbled sentences, the kind of introvert that just latches onto a group and goes wherever for the bare social contact needed. Hell the only reason he’d even come with them on this trip was cause some of the local tribes had a lot of folklore involving sharks and gods and a bunch of other stuff Ethan had pretended to listen to on the trip over.

“Well just to be safe lets ditch the dead weight on shore so he doesn’t end up getting his dick bitten off while trying to fuck a landshark.”

The upside of being so intoxicated is they didn’t have to hear any bitching from the usually talkative Gary, just a quick shove and he rolled onto the sand, a few waves lapping over his lower half as his speedo loosened. No one could see small jellyfish like blobs bobbing towards his exposed cock, a few rubbing against his tip before sticking to his urethra, slipping in as he gave a half grunted moan. A few more slipped in before the drunken mess was dragged up the beach by a disgruntled Ethan.

“Okay try not to drown Gary. We’re not trying to clean up another mess of yours.”

“Mm’always drrning n’pussy d-dipshNNGH.”

For a moment Ethan thought he was going to puke from the sudden jerk, Gary’s hands clutching his waist as he gave a groan before his stiffened form loosened with a satisfied sigh.

“I’m taking the floatie. SAM IF YOU’RE DONE TRYING TO GET THE OWNER ON OUR ASS THROW ME THE WATER BAG!”

A damp tote nearly clocked him in the head, Ethan shooting an angry glance at the rambunctious frat boy doing his best to cannonball from the shore while Danny was nervously checking the surrounding shoreline for any sign of life. Caleb was further out by the deep end, giving a thousand yard stare every few seconds before rotating and paddling out further, Ethan wondering if he was looking for sharks.

“Just sober up. I’m gonna try to relax on this fucking vacation okay?”

He took the gurgled grunts as a response and left for the shoreline, Gary currently facedown as he continued to grip his stomach, his stiff cock thrust against the sand as the blobs slowly swam up his manhood, latching onto his prostate as glands began to shift, his toes digging into the damp shoreline as blue spread over his nails.

Ethan just wanted to float, the gentle lapping of the waves making it easy to plop Gary’s large inflatable tube in and sit in the hole, letting the waves bob him as the small splashes of water chilled his dipped backside. There was a calm rhythm to it, Ethan unaware his ass was acting much like a fishing lure as it spread ripples out, his ass crack partially exposed as a silent v of movement gradually swam towards his relaxed figure. 

Ethan slowly circled around in his tube, the only real annoyance now being Sam’s constant need to yell, some dumb argument with Danny about him not wanting to be lookout or something as if there was any point as he closed his eyes and tried to enjoy the otherwise perfect stretch of beach. Some loud splashing nearby, some more frantic further away, barely any chirping from birds. All perfectly idyllic beyond his friends’ incessant yelling.

“JUST COME IN ALREADY!”

“The last thing I want is to be in a foreign jail cell!”

“I THOUGHT THESE WERE INTERNATIONAL WATERS? YO CALEB AREN’T WE GOOD? CALEB?”

“Stop yelling! I don’t know which I’d be scared of more, the sharks or whatever guards might come.”

“HEY DO YOU SEE CALEB ANYWHERE?”

“I think he went off exploring or something! Look I’m-“

“HEY THERE’S SOME KIND OF SHAPE OVER THERE?”

“What? I don’t see any-“

“YEAH IT’S WEIRD WHEN I DIVE UNDER I CAN SEE SOME KIND OFBLGGHH BLLB GLLG?!”

Ethan looked up to see Sam thrashing in the water, sitting up with a start once he noticed the manta ray like blob thing around his head. His bottom was firmly in the water as he did a second look, making sure this wasn’t some kind of stupid prank or something, the creeping V rippling under Ethan’s tube. He was easy prey, the unaware vacationer leaning forwards to try and make out just what was happening when what felt like a thick log rammed above his ass, driving the air from his lungs as Ethan quietly gasped as he was half dragged down the inner tube’s hole, unable to scream as something thick burrowed up his ass and spine. 

A few minutes earlier and Caleb was on the lookout, not in the paranoid way Danny was but with the nervous anticipation of someone about to make their dream come true. Normally an introvert like him would have done pretty much anything to avoid a trip out with such a boisterous crowd. Sure he tolerated them in small doses but a full vacation meant there was no dipping out early or saying no when he just felt socially drained. But there were sharks here, the kind you could easily swim with even if the tour guides so far hadn’t let him on the places they had stopped by. It had been the main reason he’d even suggested they take this diversion in the first place, figuring they’d latch onto the idea of an adventure.

Caleb just wanted to pet a shark in the wild. Maybe even swim if it wasn’t too put off by his presence. As a massive Shark Week aficionado he knew most sharks weren’t anywhere close to the blood thirsty menaces movies had painted and unless you were actively bleeding or in the vicinity of a handful of aggressive species, there was a good chance he could see one nice and up close as he scanned the waters for any sign of the rough skinned majesties. The area was known for its tribal stories of shark gods and surely all those signs weren’t just decorations! Right as he was losing hope, a dark shape appeared from seemingly nowhere, the dark grey and white shape cutting through the water, Caleb’s heart beating fiercely as he tried to remain calm.

He was still close enough to backtrack to the shallower waters if he felt any danger, but it was odd. He had seen plenty of sharks before but this one wasn’t familiar from any of his research, its form oddly amorphous, multiple sets of teeth flashing as its head seemed to deform with the currents. About thirty feet away though, its scarred form suddenly flattened to the ground, Caleb genuinely confused what he was seeing as the thing burrowed under the sand, except there was no cloud of sand or dirtying of the water. It just seemed to vanish as he wondered if maybe he was dehydrated or something from such a bizarre hallucination. His toe scraped something as he stepped forwards, Caleb looking down through the clear, blue waters to see his feet surrounded by two concentric circles of teeth, only a confused gasp leaving his lips before the jaws jumped up.

There was barely any sign of Caleb’s predation, the shark swallowing him in one impossible gulp before its body splashed back into the depths before nestling on the sandy floor, lying prone as bumps of resistance poked at the bizarre creature. Caleb hadn’t given much thought to what it would feel like to be eaten, assuming he’d die by the gnashing of teeth than his current predicament. It was tight, hot and wet, none of this making sense as he thrashed the best he could whilst being squeezed by a constantly pulsating muscular prison. Some kind of fluid was splashing onto him, Caleb gasping as his skin burned, clothes dissolving as soon his naked body was being groped all over, a bizarre thought entering his mind as his burning cock thrust against the muscle. Was he turned on by this?

Sam wasn’t a great thinker in the best of times, and while he wasn’t as shitfaced as Gary, he was definitely confused by what seemed to be one of those mirage things. When he dove under the water he could see some kind of grey blob in the distance thrashing, but from above it seemed to vanish. Rather than connecting Caleb’s disappearance to that though, he was amused by the weirdness, laughing it off like Danny’s concerns as he bobbed above and below the surface, enjoying the weirdness up till from seemingly nowhere his own blob appeared like a manta ray in hiding, the billowing fronds of it quickly wrapping around his head as he was dragged into the water.

It was like a plastic bag with the consistency of vellum, the slick material clamping over his head, the whole thing pulling tight as Sam’s hands went to rip it apart, only to be stunlocked by the most bizarrely erotic sensation of his life. From manta ray to more of a jelly fish, it surrounded his head, something sweet filling his mouth as it pulsed, the lubricated folds thrusting into his ears as Sam’s body grew hot. All the blood flow from his head rushed straight to his cock, dulling his responses, the asphyxiating grip doing his limited mental facilities no favors either as more of the billowing creature thrust inwards, hairs starting to poke through the shimmering membrane as his features distorted.

He flopped about, too many sensations at once, his eyes stinging as the squeeze of the headbound sack popped bones, any pain blocked by a flood of ecstasy as his ears continued to be plowed by the invading force. It didn’t take much to override his former self, his squashed features moaning as his brain was basically scrambled, libido cranked up and up as a desperate urge to mate took over his higher order brain functions. Tighter and tighter the creature grew, not just suffocating but molding, something amazing flooding in as it continued to pull inside, his lips feeling bloated and sore as they pressed against the thinning membrane, large amethyst eyes closed in bliss as the squeeze tightened.

He just wanted to give in, his brain rewarding him with such immediate submission with a deepening of the pleasure as if he was sinking in it, his skin tingling as hairs and moles scraped away against the shallow seabed, his flailing form landing ashore as the pressure mounted against his throat and the sides of his head, his cock erupting as three moist pops broke through the membrane. Sam felt utterly dazed, everything spinning as it felt like he was being double skull fucked, his moans sounding internal, an utterly sexy and girly voice rumbling through his scalp as the daze made that feel more and more right.

GIRLY SILLY SEXY HORNY MATE MATE MATE

It was all he could think, his body spasming against the shoreline, every squeal further quaking his brain to jelly as pressure built, ramming against the top of his skull as his cock unloaded further. He couldn’t think, hands desperately trying to resolve the pressure, feeling up the sides of his head as he felt two smooth cheeks leading to… nothing? Wasn’t he supposed to have something there? Things for hear-

GIRLY SILLY SEXY HORNY MATE MATE MATE

Her mind was being crushed, tidal waves of arousal crashing over and over as her hands slid past her earless face, feeling the flesh bubbling under her scalp as crackling pops burst with spurts of hair, a twirly ahegao torn out by his hands as it felt like every thrust was thoroughly pounding something flat, her hands grabbing two squirming tufts and pulling till-

“YASSSSSSSSSS~!”

There was a wet peeling flop as black and white hair spilled down her cheeks, her hands pulling out two floppy pairs of orca ears as the rough handling of such new, tender erogenous zones is enough to make every last drop of semen spurt out in a dizzying spray, masked by the foamy spray from her splashing as her swim trunks slide down her legs. She was still rock hard, but different urges were filling her, her dazed horny frat boy desires not taking much to become feminine hunger, her former self thoroughly erased as the horny shark girl tugged on her ears eagerly. It was only as she heard some wimp’s squeals did she stop, Shy groaning at the sight of another man as her cock began leaking slicker fluids. 

MATE

Gary was doing plenty of his own lewd grinding, sand muffling his moans as the inebriated host couldn’t understand the heat coursing through his veins, those small blobs sending jolts into his innards, his speedo stretching as his hips were slowly spreading, toes all painted blue as they wriggled and shrank. He didn’t just want to cum, he NEEDED to, unaware his tubes were slowly being rerouted, balls gradually rumbling as more blobs swam into his sack, feeding off the testosterone as his feet began to visibly pulsate and shrink, then his calves. Networks of muscle and neural hookups were being reworked, his skin tightening as every hair popped off, his groans hitching a bit as his balls suddenly thrust upwards. Still no release though, all of that horniness backflowing and ramming his entire back up as a lump throbbed above his tail bone.

“Gyyyysh heeehgllp NNGH AHHHHH~!”

Another thrust, his dainty toes flexing over shrunken heels, his athletic calves retracting into themselves as his figure grew lopsided, everyone else too distracted with their own problems to hear his muffled groans, Gary too out of it to even put up much resistance beyond grinding harder. It felt so good and made the buzz hit harder, the lump over his ass spreading into a blubbery blue lump that felt like a giant cock thrusting and thrusting and-

“OOOH OOOHGAHHHD G-HNNAA~!”

There was a meaty pop as the jagged edges of a fin erupted above his ass, then another, each failed orgasm making the tail’s base spread as each fucking extension pried his hips wider. And still no release, his stiffy harder than it had ever been, made all the more tender by the hot sand he was thrusting into, girlish calves rubbing together as more mass pumped upwards, ramming into his thighs as the smooth, billowing flesh made his drunken spasm quicken, already a foot of height all sucked into his plush hips as the tail continued to thrust itself outwards, his limits of pleasure raising just out of reach as his shrinking body made his BAC concentrate even higher.

The blobs were all around, swimming through his bloodstream, latching onto his brain, jolts dizzying the drunkard further as Gury tried to scream but only choked on a mouthful of sand as nerves jabbed into his spine, his brain rewiring to handle a tail that was quickly taking up more of his motor functionality, his spine given a sharp yank like his balls as his squeals popped up to a girlish wail.

Ethan couldn’t even begin to comprehend what was happening, his diaphragm not quite punched but pulled backwards to ram against his spine as any breath in him was repeatedly squashed, his asshole trembling as the drilling penetration of something larger than his legs refused to be denied as his hips were brutally wrenched apart to fit the thick appendage parasitizing onto him. At most he could do some strangled huffs, eyes rolling upwards as the only saving grace to feeling his whole pelvis dislocated as the moment the thick drilling edges of the tube stabbed into his prostate.

“HHH- UHH- HHH~!”

It felt like a giant slippery eel had swallowed it whole, Ethan’s eyes crossed and raised, his face distorting as the tube like structure tore into it, his body spasming as eruptions of cum splashed down his thighs, the organ’s desperate throbbing like finding an entirely new way to have sex as his masculinity wasn’t drained, but wrung out brutally as the drilling suck pulled at two edges and pulled. He was being fucked like nothing else, feeling like at any point his body would break apart as sparks flashed across his eyes, blood vessels popping from stress as a bloody tint filled the sky. He couldn’t even look down to watch, any time he’d pass out a burst of adrenaline forcibly pumped into his body as his entire lower half felt like a massive bloody bruise with every nerve ending set to feel pleasure.

Suddenly his knees smacked together, Ethan gurgling as his hips were rotated, the invasive presence pumping something hot and bubbly into his body as his legs kicked and spasmed. They felt… thicker? Smoother? He could barely raise his head, gasping silently as his cock continued to unload down thighs that were inflating like a water balloon on a tap, the top layers of skin loosening and splitting off as his thighs were simultaneously smooth and rough, irritating and pleasuring a cock  between cream colored shark skin as their thickness made it near impossible not to keep squeezing and battering the thing.

CLENCH

“HFF HHH HAAAA HHHHH MMM?!”

It hadn’t stopped drilling, his prostate being digested and spread as tubes squirted to either side, his ass giving a splash with each internal smack as the thickening cheeks and shifting internals made his legs begin to pinwheel. It was at his cock, IN his cock, tendrils and nerves wrapping around his balls, his constantly cumming cock slipping out his trunks as it jerked unnaturally all over the place. Something was licking at the insides, Ethan’s brain sparking as his cock was fucked from behind, ropes of nerves cumming out the tip before clasping onto it, no more of his slick, thinning fluids able to escape as his cock turned into a pink, rapidly sensitizing organ as his oxygen deprived brain tried to make sense of any of this.

It took everything just to watch, his pulsating core sucking thinner, his feet splayed as the bones were sucked in, his toes trembling as sharper nails popped out the old, the pain all swallowed by the mind rending suck as the edges of the tube thrust around his balls, the nerve filled cord tugging back as his cock angled straight up.

SUCK

Both his eyes were blood red, his silent gasps throatier as more hot pulses of something flowed in from the thrashing connection, his cock rock hard as it began to churn his guts, bobbing at every pull, thrusting inwards as he realized what was about to happen as his eyes traveled up his curved feet, his slender calves, the thick, gleaming flesh of his thighs that squeezed around his sinking cock as he realized-

GULP

“NNGH MMMGH HOOO HHHHHAAAA~!”

He wanted it. The edges curled around his balls, gobbling them down as a chasm split open, cock shoving halfway inside the lubricated gap as semen and slicker fluids spewed into the now murky waters. It was like his entire body was cumming repeatedly, each thrust sparking new nerves, the tendrils digging upwards as his cock thrust and thrust, distending more, feeling like the tip was fucking the whole thing apart as each orgasm swelled into a higher tide of bliss as his spine was invaded and connected.

CRACK

“HHFFFFFAHHHH AHHHHHH AHHHHHHHHN OHHHH F-HUUUUUUUUCK~!”

Finally he could breathe and scream, his voice cracking upwards as it roughened, his throat burning as the lump was being eaten away. All at once his heaving waist crumpled alongside his cock as he realized just what had connected to him, what was causing him to change as he could intimately feel the currents rubbing against its slick, tremendous heft.

It was a shark tail, one large enough to weigh half his body weight, that made his cock feel pathetic in comparison as it flooded it with every chemical it could to hasten its inversion, Ethen’s head buzzing as the condensed pleasure button finally pulled inside as his fresh pussy carved itself into existence. It wasn’t done, he could feel the pleasure still rising, Ethen slipping off the inner tube as he came and came and-

SPLASH 

Caleb was gasping, the fluids surrounding his body spilling down his throat, his cries getting harsher sounding as they climbed. It burned, his body slowly sticking to the insides, his flailing increasing as his limbs were pulling webby clumps of muscle that slapped them back into position, legs gripping his cock as the fluids slid into his burning, hardening shaft. The mouth of the beast opened, saltwater flooding in, burning and cooling as the mouth clamped shut, the jaws squeezing against the back of Caleb’s head as his cheeks were hugged just below the rows of razor sharp teeth.

It was pulling tighter, Caleb groaning through bubbles as his throat was massaged, his limbs sinking into the pulsating muscle as his cock rubbed against the insides till it grew clogged and stuffed into the pulsating ridges. The whole thing squeezed, Caleb grunting as he came, except rather than a release it was like something flowing, the muscle sucking on his cock, his cum integrating into the system as more spongy muscle pulled and plowed into his tip. His thrashing was turning into something much lewder, resolving to thrusting as his legs were squeezed tighter, his balls feeling mushy, bubbles erupting from his mouth as all that muscle kept squeezing, legs struggling in the grip, melding into the shark as like some kind of gelatinous mass, Caleb felt his balls slosh and slip into some kind of internal crack before loudly slurping inside the path of least resistance.

None of this was right, but more importantly none of it felt wrong to him, Something slippery sliding inside his ears, wrapping around his brain, the inside of the shark rolling and spasming as more of it thrust into his flattened groin. The more his body was grappled the more bizarre it felt, nerves mingling, burning acid and rocking currents rolling about, the spinning sharkskin shell adding to the daze as his feet wriggled, tail flicking back and forth stiffly with them lodged in there as urges spread, animalistic, violent ones, his resistance growing not because he wanted to get out but because being still was death, must swim, must convert, must mate.

Caleb only realized the truth as he felt his back rubbing against a sandy coast alongside the pulsating muscle. He wasn’t being digested by the shark, he was becoming one with it, his cock continuing to meld inside its throbbing sheath, his spread ass and tip being slid into as the fluids continued to make him more malleable.

TEAR

His fingers flexed, nails sharpening, arms compacting into something slimmer, better, his toes following as they were squeezed at every angle, something flooding up his ass as the wagging fin continued to batter his cock, the whole organ spreading as it hardened and hardened. It was being stretched to two separate points, Caleb’s shark anatomy knowledge sparking as he realized two pelvic fins were stretching it, pleasuring it, his groans rising to a horrified grunt as he could feel water rubbing at a vent between, the shark he was merging with not a male one as the female organ began to plunge into his cock.

The harder he tried to scream the more the neck of the shark collapsed, the backs of teeth rubbing against his skull, gills worming their way into his throat as his Adam’s apple got caught in the converging side vents. A few flexes and it had been expelled out his gills, the head continuing to merge, matter thrusting into his brain as tufts of blueing hair tickled the insides of their outer mouth, the back row of teeth sliding under the gums and compressing into his mouth as Caleb’s gurgles gained a feminine edge to their growling.

Two very different penetrations were happening simultaneously, a network of new nerves threading into a cock that was five times its normal size from its thinning form, a hollow nothingness teasing the inner slit as new muscle continued to spread it open. And from behind a great surge of mass, the shark’s body hollowing out further, all that muscle and girth plunging into his ass and swimming under his skin, small ruptures bursting and cycling back into his growing bottom, his squirming thighs, Caleb fucking and being fucked from every end imaginable.

His gums were writhing, sharper teeth grinding away his old from behind as he gnashed them, all of it building towards an inevitable collision as too much mass and utter nothingness crashed together right between his prostate. Everything was squeezing, the shark’s skin rubbing against him, threading down the gap plowing his cock open, his sharpened toes digging and clawing through as his legs struggled against the muscular tail. He was going to pop, going to burst, going to cum, the water foaming up with cum and blood and all sorts of fluids as all of them reached a tearing point the moment both forces caused his masculinity to flatten under the deep sea pressure. 

RIIIIIIIIIIP~!

Her new slit burst open, the slippery shark skin wedged inside her pussy as her legs kicked free, tearing out the bottom as her scarred tail flopped left and right, the act of controlling it like gaining a second body, an erotic appendage that made her slit leak as she squirmed under the surface. So much was rushing into her she could barely keep a single thought straight as her fantasies merged with the simpler aggression of a great beast, her irises flashing multiple colors as they paled to an icy blue. Swim sink fuck mate must hunt yes yes but first breathe?!

The gills were not quite functional, her top half still inside despite her mighty legs’s best efforts to right herself, the sharp tail slapping and slashing against her thighs as small cuts formed. She needed to float, needed to merge, survival instincts easing the merge as the former shark head peeled away into a hoody, the ovular body suddenly collapsing in the middle to a toned, muscled core as all that mass squeezed into her massive tits.

RIIIIIP RIIIIIIP

“AHHHHHHHN AHHH YES YESSSS~!”

She nearly bit her own tongue off as the bulging air bags sent her rising to the surface, her husky voice moaning in utter bliss as both shark and shark lover indulged in the pleasures of their new body, groping a thick tit, rubbing their thick tail as it slapped against the water. The half shedded skin that had started this all squeezed tightly into a combo one piece shark hoodie swimsuit, drool spilling past rows of teeth as her nose twitched, eyes darting hungrily towards the shore.

Blood. Prey. Host.

“Hiiiiya sexy~!”

Danny had been looking the other way when Sam had been taken over, only hearing some thrashing and odd moaning that quickly rose into the wettest of dreams in audio form. By the time he turned around, one of the hottest girls he’d ever seen was drooling, though her positioning was awkward, her head bobbing above the waves and everything else hidden. For some reason the water was much murkier around her, something off about the blurry outline beneath the waves that seemed much larger than it should have. And where had Sam-

“Oh god, all my friends already found some hunks to have fun with, but I wanted someone smaaaarter~. That you?”

Shy’s fingers were digging into the shoal, not even hiding the moans as her beefy fingers squeezed themselves slimmer, her cock leaking plenty as her muscly body squirted its melting bulk out bit by bit. She was so horny she’d honestly be fine just fucking that dweeb into another one of them, but he had to enter the water proper to let the process happen and she didn’t want him escaping onto land and ruining their fun. Besides it wasn’t like she needed the encouragement to make herself sexier as her nails turned purple, slender hands squeezing their wrists slim as her cock continued to leak driblets of shedding mass.

“Erm w-well yes I definitely have more brains than most of the members of our group and you clearly have good taste if-“

She let him yammer on, letting breathy gasps leak out as if she was turned on by his words and not the worming sensation of her former muscle leaving behind soft, fun to grab flesh. Speaking of easy to grab, the more mass that slurped into her frame, the more that caught on her nipples, inwards thrusts quickly making her areolas bulge and stiffen. It was a second double penetration after the one in her ears, any testosterone left in her system getting flushed out as the thickening catches of escaping mass thrust beneath, her pecs growing thicker and blubbery, her dug in toes similarly slimming as it took everything not to loudly shriek as her chest began to sag.

“Are you okay? You seem to be struggling with something?”

She’d be more concerned if he wasn’t curiously stumbling towards her, closer to the shore, Shy not really in a position to talk as her tits were hungrily sucking at her shoulder blades and core, her cock making the tides ever foamier as her sides squeezed like a can being crushed, one lusty howl finally escaping as it all burst out into two tremendous, flopping tits, Danny actually stumbling and falling on his ass at the sudden shock of being flashed.

“O-Oh my god I’m sorry I d-didn’t mean to look if you-“

“UHHHHNGH AHHhhh I doooon’t mind if you look.”

Even if he was trying to act above the others, it barely took much urging to have him drooling over her tits as she slowly rose more of herself out of the water. She was squeezing them together, the circular squeezes hiding their increasing mass as her tits continued to jostle and swell from her shifting figure. She could feel them getting heftier, so much of her silhouette squashing orgasmically up and up as they slapped against the water with the impact of a belly flop. All that constant rotation was like its own form of hypnosis as Danny leaned closer, watching the show as Shy continued to gasp and moan, her diaphragm squeezing, cumming out what was keeping her figure from reaching full hourglass as her spine arched, her ass the new path of least resistance as more blubber began to internally spank her thicker.

She felt stronger despite the lack of muscles, her thinning core so springy, her shrinking arches and curving calves gaining a slippery tension they hadn’t before as she tried to calculate when to just leap and drag him into the water, hoping Danny would come just a little closer… Or that was the plan till an especially harsh orgasm erupted out black and slippery, the fluids quickly squeezing around her tits and neck. Even if she was still moaning, the impossible sight was a bit too much for even a horny college student like Danny to ignore as a choker materialized alongside a bikini top. Seems it was time for her to get a lot more aggressive.

Ethen couldn’t tell up from down, his lower half ignoring his flailing arms, thighs squeezing against his new labia and letting the chill of penetrating waters further disorient him as the water filled with the remnants of his former sex. And worse it was building, his synapses firing as his bloodied eyes watered, the shark tail continuing to throb from the edge of its fin directly into his spine as more and more of its system pumped into his body. His spine was creaking, each pulse arching it further, new urges stabbing into his subconscious as lashes prickled, his brows thinning. It was climbing into his brain and did he really wanna resist? Feels like a lot of work…

Bubbles flurried from his mouth, his body sinking, his sides tethered by rising nerves as they slurped in, every contour of his core turning curved and soft. Even his flailing was feeling like a waste of energy, eyes twitching as the chemical stew from below was circulating, Ethen gurgling as the shark tail thrust between his legs and rubbed the end against his slit. The orgasmic contractions made his curving physique shift faster, the climbing bliss up to his torso, the moment it climbed above his pecs and into his shoulders like an immediate shut off to his upper body’s ministrations.

More bubbles, Etlen’s fading oxygen making the exhaustion creep up, his sinking form slowly thrusting against near invisible currents as they ran over his tail, all the oxygen running up its incongruous gills as an entirely new kind of respiration dug into his lungs. Now he was screaming underwater, his tails thrusting keeping him from drowning, more shifts in his skeleton squeezing in as his ribcage crumpled, the currents caressing his nipples as any water swallowed shot out his leaking pussy in an endless cycle of bliss.

Stop fighting. Feels good. Why would you even want it to stop? Just relax.

The bones of his skull were throbbing up and down, eye sockets widening as they angled to sultry rubies. It felt so right to give in, the pleasure climbing, his fingers flexing as that feeling of insertion spread down his arms, sucking in their bulk as his nipples perked. Every gulp of saltwater flowed under, pooling behind his nipples, the nozzle like appendages filling up as his tail pumped from behind and inside.

It was so hard to think as his breasts bubbled to life, the tail plugging in some of its mass, everything getting scrambled as Etlen’s hair bobbed down like an inky jellyfish, the red peeking under the black making him drool as the exhausted persuasion in his voice sank into his thoughts. Fuck even the thought of resisting felt laaaame as his sunken form trembled in the currents, his arms eroded down to smooth, sleek limbs, his shoulders giving only the occasional roll as they clicked in tighter, rounder. He didn’t have to do anything but take it, her favorite thing to do as the base of his brain stem was tickled, tits bobbing up and down in the currents, tail ramming into his, h-her~ oh just fucking get on with it already-

“What the fuck just- HNNGH?!”

Shy leaped, landing on his legs as she crawled up, her footing awkward as her legs were still mid change but it wasn’t exactly a challenge to pin him down.

“What’s wroooong~ I thought you were into m-heeee~!”

Her throbbing cock was still leaking, clearer beads slickly plopping out as Danny squirmed under her, trying to kick her off as her hands clawed at his swim shorts.

“Get off GET OFF GET OFF OF ME Y-HOoooo? Ahhngh wai- that’s n-hnnt faaaair?!”

Once she slipped his shorts off she had direct access to his cock, giving it a few strokes as her prey groaned, his resistance weakening, but bothersome. It took a bit of shimmying to slap her tits around  it next, letting her blubber jerk him off as she grabbed his body and began to pull, his kicks weakening the closer he got to cumming. Honestly she had half expected a shut in nerd like this to bust faster, but it was a day full of surprises as they neared the shoreline, Danny gathering all his strength into one desperate kick between her-

“H-UHHHHNGH GAAAA OH SH-HIIIIIIIT~!”

Now it was Shy’s turn to scream, his kick plowing into her balls, kicking them inside and ramming them back against her ass as pressure built and burst into the start of a thick tail, Shy seeing stars as the two of them thrashed and rolled along the beach. It was looking to be a losing battle for Shy, her prey’s legs flailing as a few more rammed into her cock, pounding it in as her own slippery releases made it harder to hold on.

They were so close to the water, but Shy just couldn’t keep hold, each length of cock plowing into her womb and erupting five times its size out her ass as she came from three spots, her slit, her tip and her quickly growing tail. In a battle of self control, there was almost no chance Shy would win as her erupting tail finally pulled her off, her hands rushing to her sinking cock as it shrank and shrank and-

SCHLUUURP THUNK

“AH AHHHHHH~ FUUUUUUCK~!”

She was seeing stars as it popped, Shy’s brains fucked half to mush as her hips widened further, letting a massive tail toss her around as a mortified Danny couldn’t help but watch in nervous fascination as her sex inverted and gushed, dampening the sand as her tail raised ass thickened by the thrust. It was a surreal sight, arousing and horrifying in equal measure as Danny continued to back away, unable to help his own erection as he watched her body spasm and cum into a hybrid goddess, everything radiating sex as her thighs finished bloating around her dripping cunt.

He was keeping a much further distance and was prepared to bolt the second she started coming towards him again, a shame he didn’t think to stay further away from the coastline as a silent v erupted out into the former Caleb, Danny screeching as her teeth nibbled at his shoulder, the muscular shark girl giving a love bite as blood trickled from her hungry lips, Shy feeling a different kind of lust as she came down from her first female orgasm and sashayed towards the chaotic scramble.

“Our turn hehe. Only fair you got rid of my cock, now let me return the favor~!”

The final nail in Etlen’s resistance wasn’t the fucking or the voice or the desire to do nothing, it came from his own jaw as the invading nerves spread, his gums aching as his open mouth bubbled in frothier shades, pinpricks jolting under his teeth as the gums shredded and loosened. Silent pops accompanied the rising shark teeth, knocking out his old flat chompers as blood drifted from his leaking gums. The crimson ribbons rose up to his nose, the smell of blood drifting into his nostrils as her eyes popped open, raw carnal need driving her brain into a frenzy as she screamed.

It all happened in a flash, nose flattening, brow compressing, Ellen’s old self cumming out as her tail snaked around her brain, a squeeze making the lovely crimson of ejected weakness make her gurgle as her swollen breasts pulled her curvy figure up once again. Thick lips sucked at the ruby droplets, her new teeth quickly pulling in cartilage from her chin and cheeks to become even sharper, her tongue darting as she fully surfaced.

“Nngh f-huuuuuck that felt goooohd~…”

It was a surprisingly restrained moan as she breathed air once more, her tail slipping out as the naked, horny shark girl climbed up to shore, feeling anemic and hungry, but really not in the mood for more work as her tongue rubbed against firming gums, her nose picking up two scents as she stared at the shore. Two of her comrades were nibbling at a flailing guy with cracked glasses, dragging him to the water as she drooled at the blood. But it looked like a massive bother, so much energy needed to drag a flailing person and she just, didn’t have that kind of energy.

“GYAAAAAAAAAAAAAAH~!”

Now that was easier, the shrinking drunkard crawling right to Ellen, his still male upper half awkwardly grafted onto a girlish bottom, tail flopping as his hands stroked a red, throbbing cock.

“N-NEED TO CUHHHHM GAAAHK SHOMEONE HEEEEL~ LOSHIN’M’MIIIIIIND~!”

“Ugh, I guess I could help if you really need it…”

She wiped away a bit of drool as she stared at the thick, blood-filled organ, more of his mass shunting into the growing rod as inches compressed from his arching back, tail wagging almost like a dog’s as he spread open his thick thighs.

Ellen didn’t want to make it obvious she wanted to do this, cause even if she did now, she didn’t want people crawling to her every time they were feeling pent up. Still it was pretty mouth watering to look at, the high pitched squeals and the throbbing half sunken balls getting her going as she began giving him some much needed service. Her tongue slid along the shaft, leaving a trail from the tip to the base as her tongue shoved against one of the pulsing blobs left.

“AAAAAAAAAA~ OHGOOOSH WHAJUSS~ OOOOOH~?!”

It slid in with barely any pressure, the skin flattening as Ellen watched one of his nipples suddenly perk pink. Another thrust and her squealing ‘master’ was squishing Ellen’s cheeks with his thighs, cock grinding against the side of her cheek as he straddled her, cute moans hiccuping as his hands played with the twin nubs on his softening chest.

“FEEELSH W-HEEEIRD BUTSHOOO GOOOOH~!”

Ellen tried to open up a slit, but the flesh was firmly springy, flattened and unyielding or at least not parting without some effort which was the last thing on Ellen’s mind. Instead she returned to the shaft, wrapping her lips around the tip, running her tongue around it as she pushed forwards, her lips working the monstrous shaft as each suck pulled in Gury’s frame, the drunk shark too drowned in booze and bliss to care as his height slipped below five feet.

So much of it was lengthening the cock, making it harder and harder to service as Ellen almost gagged on it, not helped by Gury’s constant bucking making it scrape against the back of her throat. The whole point of this was to avoid any hard work, her jaw sore from hanging open, all that warm, tempting blood throbbing against her lips, her tongue, the tip shiny and red as another thrust rammed against Ellen’s uvula as her jaw instinctively-

CHOMP

“GYAAAAA AHHHH NO WHA’DJADOOOO OOOOH OOOOOH~!”

Blinding pain nearly sobered Gury up as his head flew back, hair turning white from shock as it spilled down his back, but as Ellen’s teeth chewed into the meaty shaft something bizarre happened, a pulsing suck deep within from Gury’s tail as something shot back inside as Ellen tugged back. Gury’s features were screwed up tight, his ass getting thicker as something stirred up his innards, teeth clenched as he couldn’t tell how to react. Ellen didn’t care how he would anyways, more focused on the tasty treat draining in her mouth, filling her with energy as the splitting hunk thinned from her sucks, the ruby tip of his cock getting sweeter as her tongue scraped away any fetures, a red candy bulb left as the rest of it popped into a neat stick for her sucker, his cock a pink bobbing cone of pleasure as the changing “man” shuddered.

“MOOOOR’MOOOOHR’MOOOHRMOOOO- GYAAAA~!”

Somehow all that incredible hurt had burst into incredible pleasure, his needy thrusts worming the base of the cone in more as his sopranic screeches warped his features. Ellen tried to get a word in but quickly found her mouth filled with the remaining shaft, forcing her to reposition her lollipop as her teeth reached to the base of his malformed cock thing.

“Fnngh jsdon m’kme sw’llow.”

Gury didn’t understand her but nodded anyways, his spine crunching to a petite build the moment her serrated teeth dug into the base, all that pent up lust frothing around as slick, vaginal soup. Ellen gripped his waist for support, not even meaning to shape it as her light squeezes pulled it into an extreme curve, he was just becoming that easy to handle and play with. Even his own squeals were too much for his former self to handle, jaw popping smaller, nose shrinking up as his eyes drowned a light aquamarine. Each tug from Ellen hastened the changes, Gury’s own teeth sharpening, chest wobbling as slivers of escaping mass plumped it to two notable, but flat a cups. A bit of the shifting spunk inside squirted out, Ellen jerking back as all at once, Gura’s cock was ripped off, leaving a slit to geyser out any remnants of her former self.

“YAAAAAASH YESH YEHHHH SHO GOOHD AH AH AAAAAAA~!”

The new petite shark girl flopped on top of Ellen, the annoyed shark maid giving the husk of her former masculinity a few chews before spitting out the dissolving flesh like flavorless bubble gum. It was kind of hot watching him shrink to even below her height, some vague recollections of him being some kind of playboy in the past, not a hint left in the cute gremliny face moaning over her as the new girl came until she had been fully overtaken by her new and improved self.

“Oh wowsh haven’t gotten thish shloshed shinsh- Ehhh?”

There was a louder commotion in the water, both their heads turning to watch as the last remaining man of the group splashed about, dozens of V’s rippling the surface as the two shark girls could almost taste the blood leaking into the clear waters.

“GET OFF GET THE FUCK AGH OWW AAARRRGH!”

For some reason it didn’t hurt much when she bit into him, Danny screaming for any of his friends to help which brought smirks to the two girls licking biting his bleeding body.

“Aww and I thought you were supposed to be smaaaart~! Then again I guess you don’t normally have this happen to ya huh?”

Danny had no idea what she was even implying, wondering if they had stumbled onto some kind of horny cannibal shark cult or something as he was helplessly raised up by the muscular girl from behind. Shy nibbled at his thighs, stroking him off as he squirmed, his voice cracking after screaming so long, eyes drifting towards the sight of Gary’s face moaning in the distance. He almost missed the moment his hair burst out white, realization springing up as the rest of his body deflated into a petite shark girls, the girl who had started this emerging right where Sam had been.

“S-Sam?!”

“No it’s Shyyyy now~! Can’t wait to see who you’ll be in a bit.”

Was it too late? Was it like a zombie thing where you turn if you’re bitten? Danny didn’t know, only to find the girl behind him suddenly loosen her grip as he sprang out, wading into the water as he started running, then floating, then splashing. He didn’t know what had given him the chance but he wasn’t going to find out, doggy paddling away, unaware of Shy’s smug giggles as Caley licked her bloody lips.

Even if it didn’t hurt, he wasn’t still bleeding from multiple wounds, staining the clear waters, bubbles frothing around as first one V, then two, then dozens. It was an invisible swarm, a few clear jelly splashes paddling into his wounds as each tooth mark had its own invader, the flesh healing over tan and smooth. It was when they began wriggling into his cock that he began to feel it, his naked form trembling as his swimming stalled, panicked hands swatting at the countless invaders pouring into his navel and cock, something slamming into his asshole and another.

“Oh fuck oh fchluuughugluuurghk?!”

It wasn’t one tail, but two, both thrusting against his asshole, the two combining into an even larger black one as a third joined, his hips spreading apart as more and more of his skin was bubbling, his mouth taking on water and more of the swimmers as it felt like he was being filled to the point of bursting. Ears and lips and nose, all were being probed as he bobbed into the water, his already hard cock not taking long to spew out cum, but even that was stymied as more things were thrusting in as his shaft visibly bulged.

He couldn’t take it, hips creaking as they widened, ropes of nerves pounding into his spine as more things hoarded his bleeding form, even his body growing as dozens of tingles and buzzes poured inside his growing form. The worst was in his head, his skull shifting as he felt voices whispering into his subconscious, so many building desires coalescing into a tidal wave of change. His hands stopped flailing and swatting, far more interested in rubbing as his writhing muscle bloated, even his cock getting bigger as mass flooded his ass and thighs, his skin feeling tight as heat lapped over his tanning complexion.

It was hard to even think as the wills continued to build, his brain buzzing as his irises cracked blue, his skull bulging out as the proportions enlarged, yet as they grew they turned sleeker, his nose crimping as it thrust out a larger head, his voice cracking as his Adam’s Apple was easily gulped down a throat too wide to contain it.

“Erm… he’s not gonna pop is he? We miiiight have chummed the waters a bit too much.”

Shy was nervous her revenge was about to turn gruesome when the first loud squeals of bliss started arriving, the watching clan of shark girls all entranced as the shortest among them was quickly packing on the inches. Five sets of tails had conglomerated around his prostate, the whole thing popping as more flooded inside, each tail its own erogenous zone wiring to his brain as black hair slickly poured down his cheeks, his teeth grinding as they sharpened themselves.

He was sinking into something far more massive than he could comprehend, his own thoughts just one of dozens as his nails grew into claws, his arms and legs lengthening to keep pace with his thickening vertebrae as his cock rubbed against a forming slit. It was far too small… at first, but a cold pulse soon slowed the growth of his cock, the gap still growing as his hips spread, too wide to fit through most doors, his bubbling ass firming to two massive domes. Soon he could feel it bobbing in and out of the spreading cavern, each surge of growth squeezing it tighter inside, failed orgasms chaining as his thrashing gained a massive heft to each tremendous crash of his growing limbs.

SHE SHE SHE SHE SHE He SHE SHE SHE SHE SHE SHE

CMORE GIRLY MORE SEXYoulGROW MATE BLOODdn’GIVE IN JOIN JOINt-

“AHHH AHHHHHHHN OHHH FUUUUCK I’M GONNA-”

He was over eight feet tall now, his cock like a shrunken pinky between titanic thighs, squeezing as his hips continued to widen, the whole organ rammed in by the swarms of parasites as it unfolded and split apart inside with a tearing rip. She couldn’t stop cumming, her disappointing cock soon overtaken by floods of the parasites, thrusting in ways she had never even imagined as her teeth finished sharpening, her shoulders lagging behind in growth compared to her hips, her core even slower as it stretched up and up.

The other girls watching had to take a few steps back, unsure if she’d reach kaiju size at this rate, though thankfully it seemed to stall out when she hit ten feet. What didn’t stall were her thighs and ass, the flood of invaders bubbling up meat to pack her enormous figure, her rolling sounding like a ship overturning as she collapsed face first, the deeper end like shallows for her as the merging tail pumped away inside her shifting body. Amongst a sea of eager voices, the one holdout quickly melted into foam, the massive fucking easing her slide into conformity especially when billowing manta-like blankets wrapped around her surging femininity.

The cameltoe outlined in the forming one piece was large enough to swallow most people’s heads if not their upper bodies, her drool splattering out like its own miniature rainfall as her entire tanned body glistened with curves and power, only one flat standout remaining as her brow creased.

“UUHHHNGH UUUHHHHN FUUUUUCK K-HEEEP GOOOOOING OH FUCK I CAAAAN’T T-HAAAKE-”

It sounded like industrial churners, her nipples poking against the skintight swimsuit before pounds of muscle and fat began pumping into her chest. Shy was drooling, a full body boob job feasible as her tits swelled into a high tide. Caley was more concerned with any leftover blood in the water, Ellen was just glad she didn’t have to move and Gura was staring completely jealous, the bellowing whale shark girl’s breasts bigger than most of her petite body as her back arched, the titanic tits creating a gigantic splash and cloud of sand when they finally slapped against the shoreline.

“Uhhhngh ooh ohhh fuck yeah ahh that… that was intense. Wait why are you all so small?”

The other girls didn’t know how to respond to that, though at least they had some dependable muscle between them for the more resistant hosts. Finding that reclusive owner shouldn’t take long, and dragging her in for a nice long dip oughta help smooth over any resistance to the next step. People were always looking for a new place to visit, and a new resort sounded like just the thing to bring in future sisters by the score. It was time to start a feeding frenzy.
