[* 3rd Person POV *]
Usopp and Franky provided covering fire with projectiles and lasers, while Brook unsheated his sword ready to show them what a dead man can do and Chopper shifted into Heavy Point to guard Camie and Pappag.
Nami directed the defense with her Clima-Tact, summoning gusts to knock riders off course.
Robin stood gracefully at the railing, outwardly participating by sprouting arms to trip up several attackers.
But a mischievous, sadistic smirk crossed her face the same one from her secret memories.
During such an intense situation, There was no way she would just casually let things take place without having some 'Fun'
While the crew focused on the visible fight, she activated her Hana Hana no Mi powers discreetly. Making sure her actions blend in as it just seemed like she was attacking the bastards again.
However instead across the battlefield, on the driver's seats of multiple flying fish riders, Robin manifested clusters of her own massive, perfectly replicated asses and tits.
Soft, plush, pale cheeks with a perfect heart shape and a glistening, inviting slit appeared right where the riders sat.
In an instant the battle had changed for the riders as they had been gifted with something that they could have never imagined. Now along with the terrifying crew they also had to avoid the distraction.
Fortunately for Robin, She had done the sneaky trick in a way that her replicated body parts weren't actually visible to the crew keeping her safe.
The replicas felt every sensation as if they were her real body warm, sensitive, and erotically responsive.
The pirates noticed instantly. Rather there was no way that they could have missed such a thing.
Their aggressive charges faltered as confusion and overwhelming pleasure hit them.
"What the-?! Aaaahh~"
One rider groaned, his cock suddenly buried balls-deep in a tight, warm ass-fleshlight that had materialized under him. His body suddenly overwhelmed by new pleasure as he didn't even get a chance to avoid it.
His eyes instantly rolled up as he could feel the tightness around his dick turning him into a squirming mess as his toes curled.
The poor dude couldn't even think properly
He gripped the reins tighter but began thrusting upward instinctively, pounding the replicated ass with savage bucks. The mission long forgotten as the chance to lose his virginity overwrote his thoughts.
The cheeks jiggled violently with every impact, rippling in perfect detail. As the view began to hypnotise the man to the point he almost crashed into another one.
Robin, still standing elegantly on the Sunny's deck, felt it all. Her powers connected to her real body as she felt her ass being pounded by the man who humped like he was about to die.
She could feel her pussy twitch under her clothes as she barely held herself back from moaning.
A shiver ran up her spine as she bit her lip to suppress a moan.
'So rough… stretching me so suddenly…'
She thought to herself with a blush as she crossed her legs subtly, pretending to focus on sprouting more arms to punch another pirate.
Another rider laughed maniacally at first, thinking it was some Devil Fruit trick, but then slammed his hips forward, spanking the massive ass hard.
"Fuck yes! Take it, you magical slut!"
He didn't know how the ass had ended up in front of him but he definitely wasn't going to let it go to waste as he alternated between deep, grinding thrusts and rapid pounding.
His heavy balls slapping against the soft cheeks. As his body enjoyed getting a taste of an ass that was completely out of their league.
Robin's real body squirmed where she stood, a faint blush creeping up her neck. A moan almost escaping her lips as her knees buckled slightly. Barely holding on to the railing.
The sting of the spanks translated perfectly, making her real ass clench in sympathy. She couldn't help but cover her own ass over her dress protectively even though that did nothing.
A third pirate, more creative, leaned forward and buried his face between the replicated cheeks while still riding, licking and sucking sloppily at the tight hole while his cock rubbed against the underside.
Robin's knees became weaker as this time the pleasure was slightly different but still delicious.
'His tongue is so eager… licking deep while his cock grinds… I can't make a sound…'
The crew remained oblivious, too busy fighting.
Luffy bounced around knocking riders off their mounts, Zoro sliced through flying fish with precise cuts, and Sanji protected Camie with fiery kicks.
Usopp's shots landed true, but the pirate's coordination was breaking down as they became lost in their personal pleasures.
A fourth rider gripped the manifested ass with both hands, squeezing the plush flesh hard enough to leave marks as he used it like a fleshlight, thrusting with short, brutal strokes.
Robin gasped softly, covering it with a cough. She sprouted extra arms across the battlefield to maintain her cover, but her real thighs pressed together tightly as she desperately tried to hide her juices that were slowly flowing down.
Each rider experienced a different replica some faced forward for deep penetration, others reverse for maximum jiggle.
One particularly depraved pirate pulled his cock out and began tit-fucking a pair of massive breasts that Robin had added beside the ass, while still fingering the main hole.
The soft tits enveloped his shaft completely, nipples hard against his palms.
Robin's breath hitched, Now not only her ass was being played with but even her tits were being used.
She felt the friction on her phantom breasts intensely.
'They're using every part of me… treating my body like disposable toys while the crew fights normally… it's perfect'
The distraction worked beautifully.
The Flying Fish Pirates, meant to be a coordinated threat, were reduced to moaning, thrusting messes.
Their flying fish veered off course as the riders lost focus, allowing the Straw Hats to pick them off one by one.
"These guys are weirdly distracted!"
Usopp yelled, firing another star.
"Yeah, they're wide open!"
Franky agreed, launching a Strong Right.
Robin smiled serenely, even as another wave of pleasure hit her. She was very proud of the effect she was having while she desperately tried to pathetically fight against her own orgasms.
One rider had switched to brutally spanking both cheeks in rhythm with his thrusts, turning the replicated ass bright red while pounding mercilessly.
Another was biting down on the soft flesh, leaving teeth marks as he came hard inside her.
Robin's real body trembled each time harder than before she leaned against the railing for support, a quiet whimper escaping as an orgasm threatened to overtake her.
She maintained her composure outwardly, sprouting more limbs to help Luffy launch a decisive attack on the leader.
