[* 3rd Person POV *]
The guards stood around the pool, stroking their cocks and occasionally yanking her up by the hair right as her vision darkened.
Each time her enormous tits looked gorgeous hanging down as water trickled down her entire body...
It was paradise~
Robin gasped desperately as the guard's rough hand yanked her head above the waterline by her long black hair.
Water cascaded down her flushed face, mixing with drool and tears of overwhelming pleasure.
Her massive breasts, buoyant in the shallow pool, bobbed heavily with the motion, nipples rock-hard and sensitive from the earlier barnacle torment.
The cold water reached just to her waist when standing, but the Devil Fruit's curse made every movement feel like wading through thick mud.
Her thick thighs and massive ass dragged heavily, turning the simple act of scrubbing into an exhausting, erotic ordeal.
"Back to work, you fake whore!"
The lead guard snarled, shoving her head back underwater with a splash.
Robin submerged again, pressing her heavy, sensitive breasts firmly against the grimy tank wall. She scrubbed in slow, deliberate circles, her soft tit-flesh dragging across years of dirt, algae, and dried cum from previous captives.
The sensation was degradingly intimate the rough texture scraping her nipples while the water made her movements sluggish and clumsy.
'This water… it's sealing my powers completely. I can barely lift my arms, let alone use my Devil Fruit. My body feels so heavy, so helpless… yet my tits sliding against this filthy wall feels incredible'
'Every scrape is sending sparks straight to my clit. I'm cleaning this disgusting tank like a human sponge, reduced to nothing but a pair of cleaning udders for these criminals'
'It's perfect… I'm going to cum again just from how low I've fallen...♥'
Robin thought, her mind a whirlwind of euphoric submission.
Her pussy clenched hard underwater, and another powerful squirt erupted from between her thighs, clouding the water around her.
The guards laughed uproariously at the sight.
"Look at her go! The fake mermaid is squirting like a broken underwater fountain!"
One of them cracked a whip above the water, the sharp crack echoing as the tip lightly stung her exposed ass cheek when it dipped below the surface.
Robin moaned bubbles underwater, her body jerking from the sting.
The pain mixed perfectly with the pleasure, pushing her into her next orgasm almost immediately.
Her massive ass jiggled wildly in the water as she came, thick ropes of her juices mixing with the pool.
They added creative torments to keep her on edge.
One guard tossed several small, weighted vibrating orbs into the pool... Sabaody bubble-tech toys that sank slowly and stuck to her body like parasites.
Two latched onto her nipples, pulsing and vibrating in the water, while another pressed firmly against her clit.
The constant underwater stimulation made every scrub a battle against overwhelming pleasure.
'These toys… they're buzzing right on my most sensitive spots. The one on my clit is grinding perfectly every time I move. I can't stop squirting… my thoughts are melting'
'Being forced to clean with my tits while these things milk me underwater… I'm nothing but a perverted cleaning slave. More… shock me, whip me, degrade me further'
Robin's mind screamed in bliss as she came again, her body convulsing and sending bubbles rising to the surface.
A guard noticed her slowing down and yanked her up by the hair once more.
Robin gasped for air, coughing and sputtering as water streamed down her curvaceous body. Her tits hung heavily, red from scrubbing, nipples swollen.
"Breathe, you worthless fake! Then get back to polishing that corner with those fat udders!"
He shoved her back under, and she eagerly resumed, pressing her breasts harder against the wall, scrubbing with renewed, desperate vigor.
The shocks came next.
Another guard activated a low voltage prod, dipping it into the water near her.
The electricity surged through the pool in controlled bursts, making her muscles seize and her pussy clench violently.
Robin screamed underwater, the sound bubbling up as she came explosively, her squirt mixing with the electrified water.
'The shocks… they're lighting up every nerve. My clit is on fire, my ass is clenching so hard… I love how they control my body like this'
'I'm their electric toy in this pool, forced to clean while cumming my brains out. Don't stop… make me pass out from pleasure'
They whipped her intarchipelago sharp cracks above water followed by stinging lashes across her ass and back when she surfaced for air.
Each whip left red marks on her pale skin, contrasting beautifully with the water droplets. Robin's thoughts grew more fragmented and euphoric with every lash
'Yes… whip your fake mermaid harder. Mark my body as your property. The pain mixes so perfectly with the scrubbing and the toys. I'm squirting again… my pussy won't stop. This is heaven being punished for my deception in the most creative, degrading way possible'
The cleaning dragged on for what felt like hours to Robin's pleasure drunk mind.
She scrubbed every inch of the tank walls with her heavy breasts, her nipples raw and throbbing from the constant friction.
The guards added more elements for creativity... They poured thick, slippery "cleaning oil" into the pool that made her tits glide even more sensually while also making her skin hypersensitive.
They forced her to use her ass as well, backing up against particularly dirty corners and grinding her humongous and bare cheeks against the grime.
One particularly sadistic guard sat on the edge of the pool and used her floating tits as a footrest while she worked, pressing his dirty boots into her soft flesh.
Robin came again from the added humiliation.
'His boots on my tits… treating my proud breasts like a doormat while I clean the tank. I'm lower than dirt right now. The water is making me so weak, but my body is betraying me with constant orgasms. I adore this… I never want the crew to find me~'
They yanked her up by the hair dozens of times, always right at the edge of passing out. Each rescue breath was accompanied by mocking laughter and fresh insults.
