[* 3rd Person POV *]
Robin moved happily between the group, rimming one after another with blissful dedication.
She pressed her face between cheeks, licking deep and sloppily, humming in pleasure as her nose was smothered. It was like she was doing the thing that she was born for as there was no hesitation in her eyes.
"Your asses taste like true power~"
She spoke words that barely made sense as her arousal had cluttered her brain as she gasped during brief moments of air, before diving back in.
Fishmen groaned in pleasure, stroking their cocks as her talented mouth worshipped their most humiliating spot.
Spit from earlier asses dripped down her chin and coated her tits as she worked, turning the once-proud archaeologist into a dedicated ass-licking toy.
Her juicy massive tits hanging down and jiggling every second making her look even more debased than the cheapest of whores that were available to mankind.
The degradation only fueled her, making her grind her soaked cunt against the deck.
The Fishmen rotated on Nami, overwhelming her senses. They didn't give her any chance to even form a single cohesive thought as they planned to fully break the bitch.
One pulled out of her mouth only for another to take his place, forcing her to swallow load after load of thick, bitter cum. A taste that was absolutely disgusting for her palette at the start...
But the constant drinking suddenly caused the fluid to taste better as she began to slowly develop cravings for it.
Her belly began to swell slightly from the volume.
Meanwhile, Her pussy and ass were never empty cocks rotated in and out, stretching her walls, hitting spots that made her vision white out.
"Submit, you orange bitch!"
One growled, slapping her jiggling ass hard enough to leave handprints.
Nami tried to resist, mumbling curses around the cock in her throat, but her body betrayed her. Her hips started pushing back involuntarily, meeting their thrusts.
'No… I'm not… ahhn~ Why does it feel better than anything? Their cocks are so much bigger than anything human. Filling me completely'
'...Breaking my mind'
An hour passed in a blur of relentless use. Nami was flipped, carried, and repositioned constantly.
At one point, she was suspended between two Fishmen, one in her pussy and one in her ass, while a third fucked her tits, the massive shaft sliding between her soft, sweaty melons.
Her nipples leaking from the stimulation.
Robin knelt nearby, rimming whichever Fishman was free, her face a mask of ecstatic submission.
She even used her powers to create extra arms and mouths, allowing her to rim two at once while fingering herself.
Nami's thoughts degenerated steadily... Her previously strong will that made it seem like she wasn't ever going to break suddenly becoming feeble.
'Can't… fight anymore. Too many. Too deep. Every thrust is melting my resistance. Robin looks so peaceful licking their asses… maybe she's right. Maybe humans... Women like me are meant for this. No! I have the crew… but their cocks feel so good punishing my slutty holes…'
Another orgasm ripped through her, squirting messily around the cock in her pussy. The Fishmen laughed triumphantly.
"Look at her! The little whore is starting to break!"
They doubled down. Arlong himself took a turn, his colossal cock stretching her pussy to new limits while two others used her mouth and hands.
Nami's eyes rolled back, her body convulsing in continuous pleasure pain. Her massive breasts bounced wildly with every impact, covered in spit, cum, and handprints.
Robin, glowing with happiness, continued her assigned task.
She crawled from one Fishman to the next, eagerly spreading their cheeks and devouring their rims with long, worshipful strokes of her tongue.
"This is my place… serving superior Fishmen asses while they break my friend"
she murmured dreamily, her own body marked with footprints and Nami's cum.
The act was profoundly degrading her intelligence and beauty being reduced to rimjob devotion but it made her cum untouched multiple times, reinforcing her broken mindset.
Nami's resistance crumbled faster now. After the third massive orgasm, her thoughts shifted noticeably...
'So good… being used like this. Their strength… their size… I was so stupid resisting. Robin knew. She understood. My pussy belongs to them. My mouth… my ass… all of me'
She began moaning around the cocks, no longer fighting the rhythm. Her hips bucked eagerly, her tongue swirling submissively.
The Fishmen noticed and rewarded her with harder thrusts and slaps to her jiggling ass and tits.
"Yes… fuck your new whore harder!"
Nami encouraged as her expression finally broke away revealing her true perverted self as she had a massive wavy smile on her face completely drunk on pleasure, and they did.
Over the next stretch of the hour, Nami's mind fully degenerated.
She was on her knees now, surrounded, willingly sucking one cock while another pounded her from behind.
Her eyes, once filled with fury, were hazy with lust and dawning worship.
"Th-they're so strong…"
She slurred between mouthfuls, echoing Robin's earlier words.
"Superior… I'm just a pathetic human woman…"
Robin smiled proudly from her position rimming Arlong himself, tongue buried deep as she looked over with loving eyes.
"That's it, Nami~ Accept it. Worship them with me"
The Fishmen cheered as Nami finally broke completely. She pulled a cock from her mouth long enough to gasp.
"Please… use this worthless navigator slut! Step on me, fuck me, degrade me like Robin! I was wrong... I exist to serve superior Fishmen cocks!"
Her body shook with another orgasm as they rewarded her submission, flooding her holes with load after load.
She was passed around the entire crew, every hole used relentlessly while she moaned praises.
Her thoughts were now fully aligned...
'This is right. Being their toy, their cumdump, their doormat. My tits, ass, pussy... all for them. The pleasure is too much… I love being broken'
Robin continued her happy rimjob service throughout, moving fluidly between the group, her face never leaving their asses for long.
She licked and sucked with genuine bliss, even using her modified tongue to reach deeper, cleaning them thoroughly as a perfect demonstration of her place.
The degradation of the pretty archaeologist reduced to ass-worshipper... only heightened the scene for everyone.
By the end of the little gangbang, both women knelt side by side, covered in cum, marked by footprints and handprints, pussies leaking.
Nami's eyes shone with the same devoted, broken love Robin's had from the start.
The Fishmen stood satisfied, cocks finally spent, as the two human sluts thanked them profusely for the "enlightenment" The deck reeked of sex and submission.
The once-proud Straw Hats had been reduced to living toys for the superior race, and the breaking of Nami was complete.
