"Hey, cut it out, Shale!" Finn snarled, jumping up with a shriek as a fireball grazed him, singing the tip of his tail. The eevee's objection didn't faze the tall flareon who had attacked him in the slightest, though. In fact, the other male shamelessly sauntered closer, laughing at the smaller male while he toppled over and curled up, frantically squirming and batting at his tail to put out the smoldering fire.

"Well, that's what happens if you don't pay up, twerp," Shale sneered, opening his muzzle to blast him again.

Luckily, the flareon didn't char more of Finn's fur, but the heat still made the eevee whimper and writhe in pain while his attacker's companions, a stocky torracat and a slender braixen, stepped forward to join the humiliation. "Next time, you better get enough berries for the three of us," the fire feline cackled.

Meanwhile, the braixen dismissively kicked and poked him with his stick as if he was a piece of old driftwood. "And don't even think of hiding again. We'll find you, no matter where you are."

"Yes, yes, okay! I get it! Just… leave me alone. I'll get you your stupid berries," Finn grunted, heaving himself on all fours before limping away from the three ruffians with lowered ears.

"Make sure to find some pecha berries as well, will you?"

The eevee growled, biting his tongue not to hurl any ill-advised comments at pokemon who were several times his size. There was no point in arguing, but at least his bullies didn't assail him further, letting him leave under a blanket of crude, mocking laughter. The harassment, the humiliation, it all had gotten so much worse since Shale evolved, and there was little Finn could do about it in his current state. He was too small, too weak, and unlike the flareon, luck wasn't on his side as he hadn't found a single evolution stone yet. He couldn't run away either, since the shore was never far on this tiny island. There was still some hope left, though, because one day, he would find a water stone and get his well-earned revenge, blasting Shale until he was so wet that he couldn't cast any fireballs for a month. 

The mental image of the soaked, shivering flareon returned a crooked smile to Finn's muzzle as he hobbled toward the closest shore. While no berries waited for him among the rocks and sand, he wanted to give his luck one more shot today, and even if he didn't stumble across a water stone, the sea sometimes washed precious amber and pearls ashore that he could trade for food to expedite his toil.

At least, the weather was on the eevee's side today. A few cottony white clouds and a flock of squawking wingulls speckled the bright blue skies, and there was no wind to speak of, the glittering ocean sprawling before him as calm and gentle as it could be. After climbing across a few dark, sun-baked boulders, he finally dropped onto a narrow stretch of soft, white sand and settled right at the edge of the water. Tucking his paws and tail under his body, he sighed as he let his gaze wander across the vast sea. There was something so enchantingly serene and calming about its rich turquoise color, the scent of salt and seaweed in the air, the gentle spray of water cooling his pelt while the shallow waves playfully lapped at the shore. If not for Shale, he would've enjoyed moments like this for longer and much more often, but even a single minute at the beach relaxed him more than a whole night's rest.

If only he were a vaporeon. Then he wouldn't have to just watch the waves, but could actually join and explore them. All it took was a lousy little pebble, and just like that, his mood plummeted again. Before it sank lower than the deepest trenches of the ocean, though, a lustrous sparkle in the water caught his attention. With a curious gasp, Finn got up and waded toward the twinkle. A single look at the submerged, half-buried blue crystal made his heart leap in his chest, and he cried out in triumph because he had finally found a water stone.

But just when the eevee bent forward to grab the treasure, a shadow rose above him and the waves around him grew larger and stronger, sweeping him off his feet with a splash. He immediately tried to get up and run back to the beach, but his attempt was thwarted as a slippery gray tendril curled around his limbs, tightening around his tail first before advancing to his fluffy paws one by one. He screamed in surprise, wildly kicking and lashing out, but his squirming didn't help him as the tentacles lifted him into the air, and he froze deadly still as he stared right into the large, unblinking eyes of a fully-grown tentacruel. Its face was mostly concealed by a wide, armored blue head with bulbous, red protuberances, and at least a dozen of its prehensile gray tentacles protruded from underneath, glistening and dripping with saltwater.

In one of its appendages, the creature held Finn's water stone. Had their encounter been a coincidence? Or had it been a lure? Either way, it fueled the eevee with so much rage that he forgot about his fear and reared up with a furious howl. "Not like that! Let me go, you monster, and give me that stone," he yelled, yanking up his right forepaw to sink his teeth deep into the squishy, slimy tendril. It popped in his muzzle like an overripe fruit with a splash of purple-hued, noxious water, but that didn't stop him from chomping down even harder.

The tentacruel let out a bone-chilling cry as the eevee fought back, but it didn't let go. No, while Finn managed to free himself from one of its tentacles, it tightened down the others and ensnared him with two more. A fresh tendril replaced the wounded one, and another swiftly coiled around his neck, cutting deep into his voluminous fluffy to choke him until the struggling ceased.

Pumped on pure adrenaline, the eevee raged for almost another minute before his lungs began burning and his vision darkened, and only once he grew too winded to keep squirming, the sea monster loosened its crushing grip. Sucking in a fresh breath of air, Finn's head cleared only for him to realize the gravity of his failure, as he was still thoroughly entangled despite his violent retaliation, even closer to the tentacruel's eyes and wriggling tentacles than before. "Fuck, let me go! Please! Forget about the stupid stone, I don't care, just let me go," he whimpered, tears welling up in his eyes as he writhed weakly against the creature's hold, but to no avail. "Please."

Unfortunately, the tentacruel ignored the eevee's plea. He wasn't even sure if it understood what he was saying in general, but maybe there was some other pokemon around who did understand? In a last-ditch effort, he breathed in, opened his muzzle wide, and screamed at the top of his lungs… for about a second before the sea monster plugged his muzzle with one of its thick, vile tentacles, stifling his voice into a wretched whine while stretching his jaw so wide he couldn't bite down even if he tried. To make matters worse, a salty, acrid flavor inundated his tongue as its tip expelled a thick, slimy liquid that made him gag and choke hard.

Refusing to drink the revolting fluid, Finn tried to tear his head away from the turgid tendril only to whimper in pain as the creature whacked him across the neck with another tentacle to force his swallowing reflex. Gulping against his will, a few drops of the pitch black, oily substance spluttered from his muzzle while the rest ran down his throat like molten lead, coating his esophagus like sticky tar, and it burned even worse in his lungs as he accidentally choked on some.

At least, his tormented tissue soon numbed to the vile chemicals only for the next challenge to rear its ugly head. A much narrower appendage rubbed up against his stretched lips. With a fluttering opening at the tip and surprisingly thin walls, it looked much like a straw, but it proved much more agile and flexible when it wormed its way into his muzzle. With his head still spinning wildly, Finn only figured out the bendy straw's destination when it shoved its way through his vocal folds and down his windpipe, silencing him completely as it took his ability to breathe.

This is it, the eevee realized and finally went limp in the sea monster's hold to accept his end, but the sweet relief of unconsciousness didn't come as his chest kept rising and falling, his lungs still inflating with air. The tentacruel was ventilating him! Not only was it keeping him conscious, but it also bent aside the tendrils it had stuffed into his muzzle, tilting forward his head to make him watch what it did with the rest of its squirming appendages.

First, the sea creature spread Finn's four legs, then it darted out half a dozen more tentacles to explore his fluffy belly with a gurgling chuckle, sullying his soft fur with briny seawater and gooey, stringy slime. Stroking the eevee's abdomen and his rudimentary nipples, two of the monster's restless appendages soon homed in on his sheath and balls, squeezing and coiling around the sensitive tissue with unyielding force. Not that he could do much to stop it, merely choking and writhing in the monstrosity's vice grip, and he finally had to witness with widening, wet eyes as it slithered the bigger of its tendrils inside the fuzzy sleeve, squirting another glob of that tarry black poison inside it with a nasty splash.

Almost immediately, the liquid soaked into the eevee's concealed tip, and tears flowed down his cheeks as a fresh wave of scalding fire enveloped one of the most sensitive spots of his body. Never before in his life had he wanted to scream harder, to kick and thrash around, but the tentacruel mercilessly and effortlessly crushed his rekindled resistance, tightening its hold around his ankles and pulling his limbs apart even further until he couldn't even curl his paws anymore. And once it was done with his sheath, lathering the furred outside with another few squirts of the slimy goop, it repeated the same with his sphincter. Of course, Finn clenched it as tightly as he could, but a little splash on the supple rosy outside of his ring was more than enough to batter his rattled brain with new pain.

At least, the fiery torment only lasted seconds before an uneasy numbness set in, and while the tentacruel waited for the effects to set in down below, he turned his attention back to Finn's throat. With rhythmic wiggles, it forced its thick tentacle deeper into Finn's muzzle, invading his gullet to worm its way down his esophagus and toward his stomach, all while inflating and fattening further with its corruptive ooze. Soon, the eevee heard a pop in the joints of his jaw, and the bulge on his neck grew thicker by the moment, yet no more pain accompanied the rising pressure, just abject discomfort.

By the time the tentacruel's writhing tentacle reached the entrance to Finn's stomach, the potent toxin cocktail had taken care of his other two holes as well, dilating his anus and relaxing all the muscles in his abdomen. Losing control over his bladder too, a stream of hot piss suddenly blasted from the eevee's sheath, arching across his belly to indiscriminately douse his chest fluff and muzzle until his fur was soaked and dripping with his own urine, much to his tormentor's gargling laughter.

It didn't wait for the golden flow to cease before carrying on, however, and it unceremoniously slammed two of its slimy tentacles into the eevee's loose sphincter. Paralyzed by poison, Finn couldn't muster any resistance as they squirmed deeper and deeper inside him, lacing the insides of his ass with as much of its revolting slime as his throat while twirling around wildly to stir the wet, tarry mess and ensuring it soaked into every nook and cranny. The other appendage in his throat followed the example, dumping a fresh batch inside his stomach, and although the vile fluid spread farther than ever, the pain was muted compared to the first squirt.

Was his body getting used to the venom? Or had it just broken his nerve endings? Finn wasn't sure, but he was glad about the minuscule blessing as he couldn't have taken much more of this agony. Though, now that his insides were relaxed and numb, the tentacruel continued his exploration with twice the ruthlessness, its tendrils wiggling deeper into his guts to stretch parts that had never gotten stretched before. Worst of all, the slippery appendages were so thick and swollen that he could track their progress on his belly, watching with widening eyes as they entered his colon and squirmed all the way up to his diaphragm before following the natural bend of his intestines until they were finally as deep as they could reach.

As soon as the tentacruel couldn't gain any more depth, it added more tentacles to stretch Finn's guts even further until his entire abdomen was moving and shifting under his fur. Five, six, ten tentacles inside, the eevee had long lost count as the intense pressure and ceaseless stimulation assaulted his struggling mind. And where his sanity was deteriorating rapidly, the rest of his body responded with involuntary arousal, the writhing tendrils squeezed his poor prostate so fierce and thoroughly that he grew rock-hard from it, inch after inch of his tapered pink cock pushing out of his sheath with jerky throbs.

At least, Finn's glans looked the same as ever, neither discolored nor disfigured from the tentacruel's vile poison, but his usually so narrow urethra had opened up and dilated just like his other holes. Loose and fluttering weakly, a steady stream of pre oozed out of the opening, and of course his tormentor couldn't resist such a welcoming, thoroughly lubricated opportunity. Steadying the eevee's penis with one tendril, it slithered another toward the tip and stuffed it down his peehole, lining it with fresh, slimy poison all the way to his bladder, pumping so much of it inside until it bubbled back out in a syrupy black mix with his pre.

Fortunately, the accompanying flash of pain was brief, flaring up for just an excruciating second before it ebbed into more the same numb tingles that filled Finn's entire body, even more so as the sea monster rubbed its slippery, dripping tentacles against his paws and sides, working its toxic, corrupting black ooze into every inch within its reach. Then, once it had breached the entrance to his bladder, it began to fuck and stretch his cock as hard and thoroughly as his asshole, stretching and loosening it until it looked large enough to fit another cock inside it.

Getting thoroughly and deeply violated, the raw, relentless stimulation soon forced Finn toward the edge of a regrettable climax, but there was nothing he could do to prevent it. He didn't even have the willpower left to delay its arrival. However, just when he reached the point of no return, the tentacruel pulled out most of his tentacles, leaving just one in the eevee's stomach and one in his windpipe. The monster wouldn't even grant him the relief of an orgasm, audibly amused about his feeble quivering and the mix of letdown and fear in his eyes as his cock flexed and jumped without a single drop of seed spilling from his stretched, gaping urethra. As for his tailhole, the eevee couldn't see the gaping crater, but the cool, briny sea wind reached deeper than it should've ever reached.

The abrupt peace was tainted because although the assault on Finn's abdomen had ended, he became all the more aware of the breathing tendril in his throat again. The tentacruel still controlled his breath, and for some reason, his lungs were starting to burn, his overstimulated, ravaged mind clouding and his vision blurring as the flow of oxygen slowly diminished. After dragging him through hell, the beast had apparently decided to suffocate him for good, and as Finn's brain grew ever mushier, it glided a single tendril against his taper, keeping him teetering on the edge of a climax, leaking, twitching, squirming throughout his fading.

Soon, the eevee's eyelids began drooping, but just before he passed out, the stream of air picked up again, and his tormentor pulled up the water stone, teasingly dangling it in front of his face. So close, yet so far, it seemed like it wanted to rub his failure in one last time, but then, it suddenly shifted its tentacle toward his tip and slotted the ovoid stone into his loose peehole. The battered male barely comprehended what was happening when the tentacruel already jammed it down his cock, ramming it deeper and deeper until it passed into his bladder with a wet, nasty pop.

A split second later, a rush of warm, bubbly tingles emerged from the evolution stone. A soft glow enveloped Finn's soaked, beaten body while the raw violence of the action finally pushed him over the edge, making him cum harder than ever before. His abdomen succumbed to powerful contractions, his nuts clenching up and his cock flexing and flailing around in a wild dance, yet he bitterly despised the accompanying rush of pleasure as the vile monstrosity had robbed him of the most special moment of his life. He could only ever evolve once, and all his plans for evolving had been rendered null and void as the tentacruel forced his transformation. Worse still, it wasn't even a somewhat relieving orgasm, as his urethra was so loose that his spurts pooled inside his stretched dick like in a pit before draining into his bladder.

Fully aware of the misery it caused, the sea monster laughed at Finn with that disgusting, gurgling cackle that sounded more like a filthy mud volcano erupting than an actual pokemon. Then, it slammed its tentacle back into his pisshole, churning the sloshing mess inside him while adding fresh squirts of its tarry black poison. The other slimy tendril in his stomach opened as well, stretching and writhing inside him with wet sloshes and gurgles as it pumped an entire gallon of its nasty goo into his intestines, rapidly inflating his belly into a fat, swollen dome of tarry ooze while howling out in a mind-crushing polyphony, the red globes on its head cap lighting up. Was it cumming?

Finn barely had time to think about the tentacruel's unrelenting eruption as it pushed itself off the shore and dove into the water. In the brief moment he was above the waves, he caught sight of the beach, a pair of zebstrika galloping across the sand toward the boulders behind which it had raped him. While he couldn't make himself noticed, the sea monster's own howl roused their suspicion, and the eevee's gaze met theirs for another second before he got swallowed by the waters of the sea. The cold, salty wet rushed past his body as the tentacled pokemon dragged him into the abyss in a senseless plunge. Where was it carrying him? To its den?

All the while, the eevee's evolution was picking up pace regardless of the tentacruel's orgasm and writhing tentacles, and a fresh wave of crushing despair strangled his own climax when he noticed it. Not only seemed his last chance at escape gone, but the brightening glow of transformation that veiled his body carried an unhealthy purple hue that he had never seen before. Even Shale's evolution had happened in a flash of pristine, dazzling white, while his own was surprisingly dim. In his suffering, he could only hope that it was just the water that twisted his perception before his senses finally stopped working.

For a brief moment, Finn suddenly felt freer and lighter than ever as his mind separated from his broken, violated body, residing in a domain beyond the tentacruel's reach. Sadly, the relief didn't last long, and before he knew it, he was thrust back into the cool, twilight depths of the ocean, but he didn't find himself in the same sorry state as he had left. No, he could finally breathe freely again, see almost as clearly as on land, and the wetness of the water hardly bothered him anymore as it rushed around his now smooth, rubbery blue skin, yet he experienced little joy at his complete evolution as the tentacruel forced itself back into his vision.

Thankfully, the sea monster wasn't as unfathomably gigantic anymore compared to Finn, just about twice his size, but it was still overwhelmingly strong, its tentacles cutting deep into his skin as it spread him apart for its viewing and molesting pleasure. As before, its other tendrils squirmed all along his belly and sides, exploring every nook and cranny of his freshly-evolved body, but when it inevitably hooked a few of them into his slit and anus, it managed to pull and stretch him open with almost frightening ease. And when it applied a fresh layer of its poison, clouding the water around the vaporeon with its vile black essence, there was no burning sensation and no pain, just a mind-breaking surge of arousal as the liquid overwhelmed him like the most potent pheromones.

Within seconds, Finn's cock burst out of his slit and inflated to its full size, growing so large it reached halfway across his body. Its shape had adapted to his new habitat, enlarging from his narrow tip to his bulging slit in an even taper, and where his balls had migrated into the base of his thick blue tail, his anus was now just below his cock, a large, puffy pink hole at the end of his slit so loose and slippery it could've taken his spread paw without much stretching.

The vaporeon's budding fascination with his new equipment was cut short as the tentacruel tugged on his tail, and when he looked up, he realized that he wasn't the only one who had gotten hard. The sea monster was floating just above him with a tapered erection that was even larger than his own. Unlike its tentacles, it was a squishy, fleshy pink as it sprouted from a cleft at the bottom of its underbody and lined with hooked ridges and nasty barbs. Likely the creature's true reason why it had evolved him, as he could have never taken that behemoth of a cock as an eevee.

Even now, with his larger body, this posed a terrifying challenge, but that absolutely didn't stop the tentacruel. Coiling a dozen more tentacles around Finn's body, it aligned its tip with his anus and rammed it in, impaling him with more than one foot of fuck meat in a single brutal thrust. But rather than with excruciating pain, his ass embraced the violent insertion with a rush of dazzling pleasure. It readily yielded to the spiny monstrosity as it bulged his abdomen before tightening up hard, snugly wrapping itself around the intruder to massage it with powerful contractions. And when the sea monster pulled back again, it only reluctantly let go, getting yanked out by about three inches in a puffy, pulsing prolapse before it released its convulsing grip.

The accompanying storm of stimulation flung the vaporeon into an instant orgasm. His entire abdomen burst into violent contractions as his dick flailed and whipped around, clouding the seawater with thick, milky spurts of cum, and his mind reached a new level of corrupted bliss as the tentacruel continued its assault on his contracting asshole with deep, ruthless thrusts. The fact that he was violently clamping down on its cock didn't faze the creature in the slightest as it drilled it ever faster and harder into his guts, not just loosening his ring and insides, but ruining them with malice, wielding its barbed breeding rod like a weapon to rake and ravage his prostate even if that only made the vaporeon cum harder, screaming at the top of his lungs in gushes of bubbles.

Finn's cries of bliss wouldn't last, though, as the tentacruel stuffed the thickest of its slimy gray appendages into his gaping maw, not even bothering to ease him in as it slammed it down his throat. It wouldn't remain the only one either, as two more squeezed their way into his muzzle, stretching his cheeks and lubricating his gums with the monster's black ooze while the thickest one invaded his stomach. Its dick was getting company as well, as it stuffed another pair of tentacles into his already stretched tailhole, and coiled three more around his twitching, spurting taper. The remaining two dozen entangled the rest of the vaporeon in a convulsing cocoon until only just his head and the tip of his tail still peeked out of the fleshy, writhing gray mass.

The sea monster didn't allow Finn's orgasm to run free for any longer either. Without hesitation, it stuffed three thick appendages down the vaporeon's tip where his previous evolution had only managed a single thin tendril. Stretching and pounding the narrow hole as violently as his ass, the girthy, thickening tendrils also blocked the male's remaining load from leaving, forcing it right back into his bladder with a gush of tarry poison. And while this set of tentacles couldn't reach any deeper, the ones that were in Finn's ass and throat kept going until they met somewhere within his guts.

Coiling and squirming around each other beneath the vaporeon's bulged midriff, the tendrils only paused for a brief greeting before they carried on further, traversing and stretching his distended intestines to their limits. Although he was still cumming his brains out from the mind-breaking stimulation, a strange shiver raced down his spine as the first of the tentacles popped out of his muzzle, the hollow tip wiggling right in front of his face after a journey through his entire body. Never before had he been more aware of the fact that his lips and asshole were directly connected, only for his head to fog up with fresh pleasure as the tendrils in his guts inflated with water. Within seconds, they fattened and expanded his belly so much that he couldn't only see their outline, but also their dark color shining through his bulging, translucent skin.

Finn was still staring at the squirming mass inside him when the tentacruel erupted with a blood-curdling roar. A bright, eerie red glow lit the dusky water, and the fat, spiny taper inside his ass started flexing violently, dumping spurts of thick, virile sperm into his guts to melt the gray outline of its tentacles into a cloudy, milky white.

Unsurprisingly, the sea monster's output was just as excessive as the pounding, and rather than stuffing the vaporeon with a rapid volley of squirts, it inflated him with a forceful, constant torrent of gooey, sticky fluid, imbuing every inch of his guts as his belly kept growing to larger and even larger proportions.

The steeply rising pressure subjugated Finn to another orgasm mere seconds after the previous one had ebbed, breaking his brain so thoroughly that he couldn't even begin to think about the consequences of the bloating. Instead, he closed his eyes and lost himself in the sensory assault, his abdomen ballooning further and further with wet sloshes and gurgles. It was as if his body was made for this purpose alone, naturally absorbing every drop of the sea monster's thick, gooey load no matter how much it dumped into him.

A few minutes and far too many gallons later, the throbbing and pulsing finally stopped. The tentacruel's immense climax had ceased and the vile monster was so utterly spent that it began to loosen its tendrils around Finn's limbs. For the first time since it had snatched him on the shore, he could feel something in his pawpads again, and he sluggishly writhed out of the tentacruel's slackened embrace. Not that he could do much with his new freedom, as its cock and a dozen of its tentacles were still firmly stuck inside his staggeringly bloated body, keeping his holes stretched and his brain hazy with their languid squirming and throbbing.

Fortunately, it didn't take long until the sea monster's barbed fuck rod deflated and retracted on its own, and now that it had satisfied its depraved urges, it didn't seem too keen on dragging the stuffed blob of a vaporeon around any longer than strictly necessary. With a grunt, it began to wiggle and tug on its buried tendrils, slowly but steadily extracting it from Finn's guts until they popped out of him, one by one. Then, once the had yanked out its last tentacle, it backed away with a powerful push and no further interaction, leaving him weirdly empty and completely alone in the murky depths of the sea. 

Rubbing his bulging, overinflated belly with his forepaws, the vaporeon soon noticed that the sloshing had stopped, the sensation of flowing liquid gone as the sea monster's semen had congealed with his tissue, and while he couldn't see his ruined, gaping asshole behind the milky dome that protruded from his center, a substantial trail of milky white leaking from his depths, filling the salty waters with the smell of the tentacruel's virile semen.

At that point, Finn finally understood his abductor's true intentions. The tentacruel hadn't just abducted and raped him for its own twisted enjoyment, but it had deliberately evolved him into a vaporeon, weakening and corrupting him with its poison to turn him into the perfect incubator. Full and bloated with its seed, he could hardly move, floating across the twilit depths like a piece of lumpy driftwood, while fully exposed and vulnerable to any female tentacruel lured to his location by the cloudy trail of sperm. One by one, they would come to plunge their fat ovipositors into his loose ass and fill him with their eggs, swelling his guts with alien life while he could do nothing to stop them…

However, his own strange, depraved fantasies barely shocked the vaporeon. On the contrary, the prospect of serving the monsters of the sea again excited him and made him groan in sore disappointment when he couldn't reach his growing, throbbing dick while his bloated belly was in the way. Somehow, even though the tentacruel was gone, Finn was left craving more of that unyielding ruination, as the male had corrupted and broken him so thoroughly that he never wanted to leave the ocean ever again. In its wicked way, it had made his long-desired evolution into a vaporeon more special than he could've ever hoped for, and instead of dashing across the waves to take revenge on Shale, he had ultimately become the ocean's perfect, willing fuck meat. A sleeve so tight, yet stretchy it could take any cock and load while every fiber of his evolved body ached for more stimulation, for more of that addictive, corrupting rush of getting used and broken, and when he closed his eyes with a smile, he drifted off in the hopes that he would wake up to a horny lanturn ravaging him, maybe even a wailmer impaling him on his giant cock, or a tentacruel heavy with eggs and in sore need of an incubator violating him from all sides.

Just anything to make him cum again, and again, and again forever.
