The East Blue sun beat down mercilessly on Arlong Park. The massive, fishman-built fortress loomed like a monument to tyranny, its shark-tooth architecture casting long shadows over the enslaved villagers. Arlong and his crew were in a foul mood — weeks of Nami’s “tribute” delays and rumors of a rubbery troublemaker heading their way had everyone on edge.
The Going Merry arrived under false pretenses. Nami had “negotiated” their entry, claiming she’d brought new crew members and extra beri. In truth, she had spent the entire journey quietly lacing every meal and drink with a special aura-infused aphrodisiac brew Eros had given her — tasteless, slow-acting, and devastating when combined with direct exposure.
Luffy bounded off the ship first, grinning wildly. “Alright! Time to beat up some fishmen and save the village!”
Zoro followed, moving with a slight, permanent sway in his now-massive ass. His chest strained heavily against his shirt, thick nipples clearly outlined. He kept one hand on his swords, eyes scanning for threats… and trying to ignore how sensitive his body had become.
Sanji lit a cigarette, legs still long and elegant but trembling faintly. His chest had begun to swell into soft mounds that he hid under a loose shirt. Every time he looked at Nami, his heart eyes flickered with something darker — shame, lust, and growing desperation.
Usoppia — formerly Usopp — pranced beside them in her skimpy jester dress, massive tits bouncing, legendary ass clapping with every theatrical step. She had a permanent pink blush and a dreamy, cock-drunk smile.
“Wow, this place is so dramatic~! I can already feel the inspiration for new gossip!” she sang, twirling so her dress rode up and showed her dripping cunt to anyone looking.
Nami forced a smile. “Just stay close. Arlong is dangerous.”
Inside the main courtyard, Arlong waited with his elite officers — Hatchan, Kuroobi, and several dozen fishmen grunts. The shark-man grinned wickedly when he saw Nami.
“Well, well. If it isn’t our favorite little cat burglar. Got my money, witch?”
Nami stepped forward, playing her role perfectly. “I brought more than money this time. New crew. Strong ones.”
The negotiations quickly turned into a brawl when Luffy punched the first fishman who looked at him wrong. Chaos erupted. Swords clashed. Rubber fists flew. Fishmen roared.
That was when Eros made his move.
While the Straw Hats were distracted by the frontline battle, a small strike team infiltrated through the underwater tunnels Nami had secretly marked on her map. Eros led them personally, accompanied by Morgana, Bubbly, a dozen elite clown and Marine sissies… and several newly converted fishman sissies — their bodies remade into exotic, scaled, curvaceous sea-sluts with gills, sharp teeth, and absolutely obscene proportions.
They emerged inside the kitchens and lower barracks.
The first victims never stood a chance.
A group of fishmen guards turned a corner and walked straight into a pink mist cloud. Their muscular, imposing bodies began transforming with wet, grotesque beauty. Broad shoulders narrowed. Chests exploded into massive, scaled breasts. Hips widened dramatically as powerful fishman tails reshaped into thick, breedable thighs and legendary asses. Cocks inverted into slick, aquatic cunts that immediately started drooling seawater-scented slick.
One massive shark-type fishman dropped to his knees as his transformation completed, now a towering, shark-toothed beauty with enormous tits and an ass that could swallow a cannonball.
“F-fuck… feels so good… Master… this sissy shark cunt needs filling~!”
The infiltration spread like a virus.
Back in the main courtyard, Nami’s betrayal reached its peak.
During a brief lull in the fighting, she “helpfully” distributed water gourds she had prepared earlier — each one heavily spiked with Eros’s aura aphrodisiac.
“Here, you must be thirsty after all that fighting,” she said sweetly, handing one to Luffy first.
Luffy chugged it without hesitation. “Thanks Nami! You’re the best!”
Zoro took a long drink, too exhausted and agitated to question it. Sanji accepted his with heart eyes, none the wiser. Even Usoppia drank deeply, though she winked at Nami conspiratorially.
The effects hit fast when combined with the lingering mist now drifting across the battlefield.
Luffy suddenly laughed louder than usual, his rubber body tingling strangely. His shorts tightened around his ass as it began to slowly, subtly swell.
Zoro growled, gripping his swords tighter as another wave of heat slammed into him. His already swollen tits grew another cup size, nipples leaking tiny droplets that soaked through his shirt. His cunt — now fully formed — clenched hard, dripping down his thick thighs.
Sanji dropped to one knee, breathing heavily. His chest pushed outward noticeably, forming soft, perky breasts that made his suit jacket strain. His legendary legs trembled as his ass plumped.
“W-what the hell is this… Nami-swan… something’s wrong…” he gasped, face flushed crimson.
Nami bit her lip, thighs pressed together in dark arousal. “Just the heat. Keep fighting.”
Eros and his team burst into the courtyard from the side entrance at the perfect moment.
“Miss me?” Eros called out, pink aura exploding outward in a wide, heavy pulse.
The already drugged Straw Hats were hit hardest.
Luffy stumbled, laughing drunkenly as his ass ballooned further, stretching his shorts to their limit. “Shishishi… why does everything feel so… tingly and good?!”
Zoro roared and charged Eros directly, but his movements were compromised. His massive tits bounced heavily with every step. His fat ass clapped audibly. His new cunt drooled constantly, making his thighs slick.
Sanji tried to launch a fiery kick but tripped over his own swelling ass, landing on all fours with his growing tits squishing against the ground.
Usoppia immediately ran to Eros’s side, dropping to her knees and nuzzling his thigh happily. “Master~! Your Gossip Bitch missed you! Look at them~ They’re all getting so pretty already!”
The fishman sissies swarmed the Arlong crew from behind. Arlong himself watched in rage and dawning horror as his strongest warriors were turned into scaled, aquatic cock-sluts one by one — their powerful fishman bodies remade into hyper-feminine sea whores with fat tails that turned into plush, breedable asses.
Hatchan tried to fight but was quickly overwhelmed by three clown sissies who smothered him in tits and ass until he was moaning and begging for Master’s cock.
The courtyard became a battlefield of corruption.
Eros dueled Zoro directly again, this time while the swordsman was heavily compromised. Every clash sent more aura into him. Zoro’s swords grew heavier. His mind kept flashing with images of dropping to his knees and offering all three holes.
Sanji was cornered by Bubbly and Morgana. The two elite sissies teased him mercilessly — grinding their bodies against him, whispering about how perfect he’d look in a maid outfit, how good his cooking would taste with cum glaze. Sanji’s resistance was crumbling fast, tears of shame and lust in his eyes as his body continued to feminize.
Luffy, still fighting hardest, was laughing and stretching wildly… but even he was starting to show signs. His rubber ass had grown into two fat, bouncy cheeks that jiggled every time he used Gear Second. His chest had small but noticeable swells, and his voice occasionally cracked higher mid-laugh.
Nami stood on the sidelines, watching everything with dark, hungry eyes. Her betrayal was complete. She had delivered her former crew right into Eros’s hands.
Arlong finally charged at Eros in a rage. “You dare corrupt my crew, human?!”
Eros simply smiled and hit the shark-man with a concentrated pulse. Arlong’s powerful body began changing on the spot — muscles softening into thick, feminine curves, chest exploding into massive shark-titted breasts, ass swelling into a powerful, scaled dumptruck.
“You’ll make a magnificent sea queen slut,” Eros laughed.
As the sun began to set over Arlong Park, the fortress had fallen into Eros’s hands.
Most of the fishmen were fully or partially converted. The Straw Hats were exhausted, drugged, and heavily exposed. Luffy was still standing, but barely. Zoro was on his knees, panting, tits heaving. Sanji was curled up, trying to hide his growing breasts. Usoppia happily sucked Eros’s cock in celebration while recounting every humiliating detail to the defeated crew.
Nami finally stepped forward, dropping all pretense. She walked over to Eros and kissed him deeply in front of everyone.
The Straw Hats’ faces twisted in shock and betrayal.
“Nami…?” Luffy whispered, voice small.
She looked back at them with a cruel, satisfied smile.
“Sorry boys. But the future is pink.”
