Party Under the Sea
Chapter Three

Thousand Sunny

The bathroom was silent for a moment as Nami stood there to process what she was seeing. Her Fishman fuck buddy was currently naked sitting on the floor with an equally naked Robin sitting in his lap, cum leaking out of her holes. "Robin? What the hell?! When did you know about Caludo?"

Relaxing into the orca Fishman's lap, the pirate archeologist gave her good friend a knowing smile. "Oh come on, Nami. You thought you could fuck a Fishman all over the Sunny and I wouldn't find out?"

"Yeah, I guess you're right. You knew we were fucking probably before we left Fishman Island, didn't you?"

"Yep."

"Should have figured..." Nami facepalmed, keeping a hand on the towel that barely covered her curvy body. "Please tell me you didn't tell the others. Sanji will turn Caludo into sushi. But I'm kind of relieved..."

"Wait, why are you relieved?" asked Caludo.

"Well, of all my crewmates, I'm glad it was Robin who found you out. Although..." She noticed how much was leaking out of Robin's asshole. "I'm more glad that she didn't break you. I would have gotten angry at Robin for that. But seriously, guys," Opening the door, she peeked out into the hallway to make sure that none of the other members of the Straw Hat pirates were coming. "You should know that somebody is bound to come in."

"Right. We should probably get up." As if shrugging off the fact that she just had a Fishman-sized cock in her ass, Robin stood up and grabbed a towel to cover herself. Looking out one of the portholes, she noticed that the Sunny had reached land. "We made port already? That was quick."

"Yeah. While you two were in here 'showering', we reached an island to restock our supplies. I convinced everyone to go ashore and that I was okay with guarding the ship while Luffy and the others were out and about." She looked over at Caludo and gave him a soft smile. "It seemed like your best chance to get out of here and get back to Fishman Island. You'd better go now before Sanji gets back."

Seeing his chance to leave, the black and white Fishman nodded. "Got it. Thanks for that, Nami." The guardsman stood up on wobbly legs, his body still tired from the gauntlet that Robin had just put him through. "Let me just get my clothes and then-"

Caludo never finished. His webbed foot stepped on the bar of soap that Nami had dropped when she first walked into the showers. Both Robin and Nami gasped when they watched the Fishman slip and fall backwards, the ship shuddering from his heavy weight hitting the tiled floor.

"Um...Caludo? You okay?"

Robin walked around the orca Fishman and knelt down beside his head. "Yep. He's out like a light."

"So now what? We can't just leave him lying here. Sanji always takes a shower whenever he comes back to the ship after buying food since carrying so much meat makes him work up a sweat. And we can't toss him into the sea either. He might wash up on shore while he's unconscious and get captured by slavers."

The pirate archaeologist tapped her chin for a moment before a lightbulb went off in her head. Turning over to her best friend, the naked pirate smiled. "I've an idea." Leaning forward, she whispered her plan into Nami's ear. "What do you think?" she asked after she was done.

Normally Robin's ideas made Nami skeptical due to the woman's macabre personality. But this time she was smiling right along with her friend. "I love it. And I think he," she pointed down at the still unconscious Caludo, "will love it too. Come on, let's get him back to my room."

"Will do." Crossing her arms, Robin activated her Flower-Flower Fruit powers, summoning a multitude of hands to lift the huge Fishman up and carry him out of the showers and back into Nami's quarters.

Sometime later...

"Nghhh..." Caludo opened his eyes, his webbed hand going to his head and feeling the huge lump. "Ow...where am I?" Looking around, the orca Fishman realized by his surroundings that he was no longer in the Thousand Sunny's showers. Instead, Caludo was lying in the middle of Nami's bed, back in the pirate navigator's bedroom. "Nami? Where?"

His attention was captured by a sudden whistle that came from the end of the bed. Craning his head down, the naked black and white Fishman looked down, his jaw hanging load when he saw the two pirate women standing at the foot of the bed. Neither were naked anymore, having changed into sexy new outfits once Caludo was smuggled safely back into Nami's room.

Caludo's eyes were first drawn to Nami's teal blue bra and panties. Her underwear showed off her breasts, the bra just barely containing her massive titties with the tops of her nipples poking out of the top. Her legs were complimented by black stockings that went all the way up to a garter belt that hugged her smooth waist. Robin, on the other hand, chose to wear a purple baby doll night gown that couldn't even claim to hide her flawless body. Like Nami's bra, the dress could barely contained her breasts, her nipples poking out through the ultra-thin fabric. The black thong she was wearing also had a purple garter belt that was attached to the black stockings she wore.

"Heheh, like what you see, Caludo? We bought these at the lingerie shop in the town here on this island. We figured you wouldn't mind if we left you to rest here to nurse the lump on your head. You were out like a like. But what do you think? We look good, right?" Turning around, the Pirate Navigator struck a sexy pose, giving her plump ass a good smack.

"Fuck..." Caludo stared at the two pirate women with amazed eyes, the blood quickly rushing south. "I love it. Just when I thought you girls couldn't get any hotter, you do this." He had fucked many a woman, some of them pirates even. Yet none of them compared to the two Straw Hat Pirates.

Robin dipped a knee onto the bed, smiling warmly at the orca Fishman while running a hand along her side. "I only wear this particular outfit for special occasion and since you did such a swell job earlier in the showers, I think you earned the right to see me at my sexiest."

Caludo was in agreement about one thing. Sexiest was the word that best described the dark-haired woman. He'd never seen two women who looked like two goddesses of beauty and sex. Part of him was disappointed that the two weren't Mermaids or Fish women.

Sitting down next to Caludo, Nami ran a hand along his broad, naked chest. "So after you went and knocked yourself out, Robin and I had a little talk and we decided on something."

"What?"

The smile on Nami's face grew wider. "Since we've had to keep you hidden from our crewmates and kept Sanju from turning you into sushi, then you owe us the biggest fucking of our lives. That's a fair trade. Don't you agree?"

The thought of Caludo's massive Fishman cock fucking her and destroying her pussy and asshole made Robin wetter than she'd ever gotten before. Her thong was already soaked from her dripping arousal. Her hard nipples poked through the ultra-thin fabric of her purple baby doll night gown at the thought of taking another ride on the Caludo Express. "Afterwards, you can jump ship and swim back to Fishman Island. So, what do you say?" she asked as she sat down on his unoccupied side.

The collective eroticism before him was like nothing he'd ever experienced before. If only he knew when he approached Nami back at the palace party that he'd be going through such bliss. His cock as hard as a rock while he stared at their beautiful bodies. A choice like this was no choice at all. Grinning from ear to ear, the orca Fishman slid his large arms around their curvy waists, squeezing their fine asses with his webbed hands. "You girls have got yourselves a deal."

Wrapping her arms around his broad shoulders, Robin was the first of the two pirate ladies to close the distance between herself and Caludo. "Mmmmhhh..." went the archaeologist as their lips pressed together, eagerly giving him a deep and lewd kiss. Caludo's strong arms wrapped around her curvy waist and pulled the pirate onto his naked lap, his cock pushing against her thong-covered pussy. One of his webbed hands reached down to squeeze her soft ass while the other ran through her long, ebony hair.

Nami slipped behind her best friend and hugged her tightly, pressing her tits against the pirate archaeologist's back. One of her greedy hands reached around to grab one of Robin's breasts and started fondling her through the baby doll gown. Her free hand snaked down the dark-haired woman's side before dipping underneath the night gown, fingers slipping beneath her purple thong.

"Mmmmh!" Robin's lips let out a lewder moan into Caludo's mouth when she felt Nami pull on her thong, giving her a wedgie. Feeling the soft fabric of her underwear dig into her pussy's wet lips along with Nami fondling her tit. Her arousal only blossomed when she felt Caludo's huge Fishman cock rub against her pussy, the thong and the baby doll dress doing little to keep her womanhood from feeling his huge length and its warmth as it continued to grind against her pussy.

Sandwiched between Nami and Caludo with the former groping her tit and making her thong dig into her sensitive pussy and the latter making her melt with his tongue, climax found the pirate slut faster than she'd expected. Still sensitive from being pounded into the shower floor, Robin let out another moan into Caludo's lips while she came, the orca Fishman's lap growing wet from her leaking juices.

"Wow, Robin, you must've really wanted this if you came that quickly," teased Nami while continuing to wedgie Robin's ass and pussy.

Robin finally broke the kiss with her Fishman lover from the need for air, a string of sticky saliva still connecting their lips. "With a Fishman who's as good a lover as this, what's not to want?" she teased, giving Caludo another quick kiss before sliding off his lap.

Eyeing the erect cock that bobbed free after being pinned for so long by Robin's lap, Nami licked her lips. "Since this is going to be our last time, I've gotta make the most of this and savor every inch of your cock." Lying down in front of the orca Fishman, Nami leaned her head down and pressed her lips against the side of Caludo's long shaft. A shiver ran up her lover's spine as she dragged her hot tongue up the side of his cock. She could taste Robin's juices mixed into his thick, manly flavor and her pussy grew wetter, a dark spot staining her teal panties while continuing to worship his cock.

"Fuck..." Caludo put a webbed hand on Nami's head, leaning back against the pillows behind him while he enjoyed Nami tonguing his manhood. "By the sea, you two are sex goddesses..."

Chuckling from her friend's praise, the pirate navigator gripped the base of his shaft with her soft hand, her tongue working its way up his veiny shaft before pressing her lips against his bulbous head. Her velvet hand glided up and down his cock as her tongue licked at his slit, his pre-cum coating her tongue and driving her wild from his erotic taste. Pushing his cock up, Nami focused her attention on his balls, his sac heavy and swollen from the need to come. Caludo felt like his whole body was melting when he felt those warm lips touch his balls, wrapping around his sac and sucking on them tenderly.

"F-Fuck!" Caludo's hand dug into her orange hair. The pressure in his cock was about to reach its zenith and he was about to blow. "Fuck, Nami! I'm-"

Just as the orca Fishman was about to blow his load and cover Nami's face in hot cum, he felt a tight grip squeeze the base of his cock, halting his orgasm before it could start. Caludo groaned from both disappointment and a little pain. Turning his head, he looked at the smiling face of Robin with confused eyes. "Not yet," she told him, pressing herself against his naked side. "It'd be more fun for us if you hold it in until we give you the word."

"I'm game," said an intrigued Nami.

"What?!" Caludo looked at both women like they'd lost their minds. But his horror was abated when he saw both women sit up, their hungry eyes staring at his cock.

Caludo found himself with two topless pirate babes pressing their huge titties against his broad chest. Their soft hands both wrapped around his long shaft and together started to give him a double-team handjob. The pleasure made Caludo's head spin, his strong arms wrapping around their waists again and holding them tightly while they made his cock melt with just their hands.

The double handjob didn't last long, however, as both women started to become hungry for the taste of his cock again. Nami was the first to lower her head and start sucking him off, her head bobbing up and down as she took her friend's dick all the way down her throat. After a minute of pleasure him, Nami took her mouth away to let Robin have a taste. Over and over again they took turns sucking him off, making Caludo feel like his balls were going to explode from trying to hold in his orgasm.

Eventually the pirate sluts took notice of Caludo's surprising willpower and decided to up the ante. Leaning forward, Nami wedged the orca Fishman's cock between her huge tits. With the teal lingerie bra still holding her tits, her cleavage became a tight vice grip, perfect for Nami to move her titties up and down without the need to use her hands. "Mmmmh, so hot. My tits feel like their melting," she cooed, her panties completely drenched by this point.

Robin wasn't willing to let Nami have all the fun. While the navigator's breasts kept his long shaft wedged between them, the archaeologist let her tongue roll out of her beautiful lips and started to lick the tip of his cock, his pre-cum addictive to her. Leaning up, the dark-haired woman gave her best friend a smile. "Mind if I tag in?"

"Sure. He's all yours."

Nami freed Caludo's manhood from her titty prison and let Robin replace hers, the baby doll dress doing little to keep her from wedging his thick cock between her huge heavy globes. The Fishman's pre-sum started to stain her dress while she gave him the best paizuri a pirate slut could give. Nami watched her friend pleasure the Fishman, her lips glued to Caludo's in another hot, wet and sloppy kiss. Taking hold of his hand, she brought it to her wet panties. The orca Fishman got the hint and slipped his fingers underneath her stained underwear to finger her, sucking on her tongue all the while.

Deciding to escalate things further, Robin pulled her tits away from Caludo's manhood and reached underneath her baby doll dress. Hooking her thumbs around the hem of her thong, sliding it down her legs to reveal her wet pussy. Shifting her position around, she eagerly shoved her ass into Caludo's face while beckoning her friend to join her. "I think he's held out for long enough. Let's let him cum the best way we know how," she told her friend.

Nodding in agreement and reaching behind her, Nami unclasped her bra and tossed the teal lingerie to the floor, letting her massive breasts bounce free in their full glory. Robin likewise whipped the purple baby doll dress over her head and let it join Nami's bra on the floor, both women now topless.

Peeling herself away from her lover, the now topless Nami crawled around until she was lying opposite of Robin. The two topless ladies sandwiched their tits around the huge Fishman member and started to give Caludo a double paizuri. Nami licked her lips as her nipples rubbed against Robins, the eroticism of it all making her hornier than she'd felt before.

Robin gave her luscious booty a good smack, signaling to Caludo what she wanted him to do. Getting the hint, Caludo's hands dug into her soft cheeks and spread them, pressing his face against her wet pussy and eating out the pirate.

The cock that was wedged between their tits started to pulse and throb like mad, hinting at what was coming. Grinning, both women ramped up the pace, moving their tits up and down in synch with each other. Anticipating what was going to happen, the two sluts opened their mouths and stuck out their tongues, both hungry for the taste of Fishman cum.

Unable to take the pleasure anymore, Caludo moaned while his tongue was buried deep into Robin's cunt as the pressure started to surge through his cock. This time it wouldn't be denied. The tip of his cock pulsed before he let out a torrent of cum and covered the two sexy pirates' faces and tits with his hot, sticky essence.

"Ahhhhh..."

"Mmmmmmhhh..."

The two pirate sluts moaned from the heat of his seed before licking it off each other, their breasts glistening with saliva once they were done. Once their bellies were full of hot, Fishman cum, they both looked at each other and knew it was time they both got what they wanted from the royal guardsman. Nami slid off the bed and slipped off her panties to join Robin in full nudity, though they both kept their stockings and garter belts on.

Just the sight of the two naked pirate babes was enough to get Caludo hard again, although considering his stamina, that wasn't a surprised to Nami or Robin.

"So tell us, Caludo." Robin laid on her side and ran a hand up her thigh while smiling at her lover. "Which one of us was the better fuck?"

"Heh. So that's why you wanted to keep me here," Caludo guessed while sitting up. Scooting over to Nami, the Fishman guard gave her a quick kiss before turning her around and bending her over. Robin was amused by the excited look on Nami's face as he brought the tip of his cock to her entrance. "Nghhh! Yes!" cried out the slutty navigator when Caludo slammed his cock inside of her. Out of payback for teasing him so much earlier, the orca Fishman wasted no time in reminding the woman's pussy of the shape of his cock.

The bed shook from Nami getting fucked from behind, Caludo wanting to make their last time count. His webbed hands reached underneath the pirate to grab her swaying tits, gripping them tightly while making her ass shake with each smack of his hips.

So horny was Nami that she climaxed quickly, gushing around his cock as her body tensed around him. Caludo gave a loud grunt before following the slut, cumming inside of her and pumping her womb full of cum.

As Nami collapsed onto the bed, Caludo pulled out of her sticky pussy, only to feel a hand reach around him and start to stroke his slickened cock. "My turn now," said Robin before sliding back into his lap. Wrapping her arms around his thick neck, Robin raised herself up and settled herself down onto his cock, her eyes rolling into the back as her womanhood was stretched once again by Fishman cock.

Sitting back, Caludo let Robin have control and watched her bounce up and down on his cock with a smile on his face. His webbed hands reached around her to play with her supple ass, smacking it and spurring the slut to move faster. Pushing one of her huge tits up, the royal guardsman started to suck on her nipple, sucking on it hard and drawing more moans from the pirate.

Nami's bedroom continued to fill with the sound of the pair fucking until twin cries of ecstasy threatened to echo throughout the Thousand Sunny. Her pussy tightening around the thick clamhammer that was claiming her, Robin's face twisted with perverse glee as she climaxed all over his lap. Pulling the woman into another deep kiss, Caludo came inside her and pumped her womb full of Fishman cum.

Time moved quickly for the three as they continued fucking like animals. Both women found themselves getting creampied two more times each before things started to hit their zenith. "So tell us, who's the best fuck, Caludo?" asked Nami, panting for breath while cum leaked out of her gaping pussy.

"Uhh..." Caludo still didn't know how to answer that question, not sure if he'd face the wrath of an angry pirate. He knew it'd be unwise to get one of them mad, considering these two faced an army of over fifty thousand Fishman and came out on top.

"Oh don't worry, I know a way you can decide." Robin crawled on top of Nami and beckoned their Fishman lover. "Why don't you fuck us both? Whoever you cum inside will be the winner."

Unable to say no to such a seductive offer, Caludo mounted the two women and started by shoving his cock into Robin's cunt, the pirate gasping as her pussy was invaded again, stretching to its limit once more. After a few thrusts, the orca Fishman pulled out and slammed into Nami's, her greedy hole sucking him in once more.

Nami clung to her friend while her pussy was being ravaged until Caludo pulled out of her and alternated to Robin. With their bodies grinding and their nipples and clits touching each other, Nami couldn't help but notice just how beautiful Robin was. Before she could act on her feelings, Caludo thrust back inside of her and any thoughts she might have had were thoroughly purged in order to focus on the intense fucking she was receiving.

Sweat poured down Caludo's body while he alternated between the two women. He could feel his balls tighten once more to signal his impending climax but didn't know which of the two to finish him. As his cock slipped out of Nami's hole, the Fishman missed his intended target and instead inserted it between the two women's pussies and found itself sandwiched between the pair. Unable to stop himself from enjoying it, Caludo thrusts his hips as fast as he could go until he finally let it all out, cumming all over their bellies and tits.

Spent and his body feeling more tired than ever before, Caludo fell back against the bed. The sticky girls quickly sidled up next to him, their bodies covered in sweat and cum. "I guess that...settles that..." Nami said in between pants.

"Yes...I guess we'll...call this a draw..."

"Heh..." Caludo wrapped his arms around his women and gave them each another deep kiss. "I think I'm the real winner here," he said with a smile.

"I agree."

"Yep."

Nami laid her head on his chest. "Rest first, then we'll let you go later."

"That...sounds good," Robin said while putting her head on his shoulder.

The pirate sluts and the Fishman quickly fell asleep, exhausted after their final bout of intense fucking...

The Next Morning...

Making sure that the crew were all still asleep, Nami and Robin led Caludo through the Sunny and up onto the deck. Dressed and ready to go, the orca Fishman turned to his lovers. "Well, I guess this is goodbye," he said.

"We'll miss you," Nami said with a heartfelt smile.

"Don't worry. I'm sure we'll swing by Fishman Island again in the future. I know Sanji will want to see Mermaid Cove again."

"Look me up when you do. I'll make sure to have the bedroom ready," said Caludo. Pulling Nami close, he gave her one last kiss before turning around to give Robin a parting kiss. "You two are the best women I've ever met. I'll miss you both."

The Fishman pulled the two women into a tight hug before finally letting go. Without another word, Caludo jumped into the ocean. Standing at the railing, the two pirate women watched their friend wave goodbye to them before disappearing into the ocean, his shadow heading in the direction of Fishman Island.

"You know what this means, right?" Nami asked her friend once they could see Caludo no more.

"What?"

The pirate navigator grinned from ear to ear. "The next time we go to Fishman Island, we're going to have Caludo join the crew."

"You sure he'd want to?"

"Oh, I'm sure we can persuade him. No way am I letting any other woman have that cock except for the two of us!"

The End
