Backstory:

This story is a continuation of "Curiosity killed the cat, or did it?" and I strongly recommend that you read it before starting on this one. If you just want to read this one then here's a short summary of the story so far:

Robin and Chopper developed a new rumble ball specifically for Robin's Devil fruit. The first batch of balls was a failure, but resulted in some very interesting and frisky situations. After many trials and errors, Chopper was finally successful and managed to create a new set of balls. Once consumed, Robin gained much greater control of her powers and the ability to create new types of limbs. The previous story ends where this story begins and the Strawhats find themselves upon a new island, full of mysteries and adventures!

Chapter 1 – A new adventure

"Holy crap, that's a suuuuper massive city!"

"Yeah, it's pretty impressive alright." Sanji replied.

"Check out the large wall surrounding it! It looks super cool!" Luffy cheered, becoming quite ecstatic.

"Yohohoho! I wonder what they are trying to keep out with such big walls."

"I don't know and I don't want to know… The entire shoreline is covered with that dense jungle… It probably has some really nasty monsters or deadly plants living there!" Usopp said; his legs were trembling.

"But don't you use plants as weapons, Usopp?" Chopper asked.

"Oh right, I do! In fact, I'm going to conquer this entire island and become the king of the jungle!" Usopp boldly stated with his legs still shaking.

"Really!? You're so cool, Usopp!" Chopper's eyes began to sparkle.

*Yawn* "Huh…? Is it morning already?"

"It's already afternoon, you moss-headed lump of dumb!" Sanji roared.

"You want to fight, curly-brow!?" Zoro retorted.

"Oh I'll fight you alright, but it will be a one-sided slaughter!"

While Zoro and Sanji were busy going at each other's throats, the rest of the crew only sighed and returned to admiring the island that was approaching them. Shortly thereafter, the door to the lady's quarter opened and Robin emerged. The light blinded her from a brief moment as she stretched in the warmth of the sun. "Fufufu." Robin chuckled, watching as the two rivals tumbling around on the grassy deck. "You two are so adorable together." She said.

In an instant, the two stopped their fighting and just stared at each other. Robin's words echoed inside their heads as they froze in place. When they had finally processed the implications of Robin's observation, the two rushed towards the rest of the crew and flung their chests against the railing. The force of the impact and their intense disgust for each other caused them to hurl everything they had eaten so far into the water below them.

"You two should get a room already…" Franky said, causing Zoro and Sanji to vomit even harder.

"Aaaah! Stop joking around with them, Franky! You're just making it worse for them AND us! Usopp continued. "I think I'm going to be sick…"

Robin held her hand in front of her mouth, desperately trying not laugh out loud. She knew that Zoro and Sanji thought of themselves as nakama, but they'd be darned if they'd let anyone point it out without immediately proving them wrong. It was then, just after the two had finished painting the water, that Robin saw the island before her. Her jaw almost dropped when she noticed the gigantic city. It wasn't since Water 7 and Enies Lobby, that she had seen such tall structures.

The buildings stretched far into the sky and seemed to be made out of several different kinds of materials. It almost looked like someone had stacked several small houses on top of each other. Robin thought it looked very odd, but wasn't all that surprised since the grand line held many different and unique cultures. There was one building though, that didn't quite seem to fit in and stood out from the rest like a sore thumb. In the middle of the city stood the tallest, most impressive piece of architecture she had seen so far. It looked to be made out of metal and glass, but also had a massive sign of the letter L on front, almost at the top of it.

Robin traced her eyes along the outskirts of the city, analyzing it to the best of her ability. It had two giant walls protecting it from the jungle just outside of it. The first, outer wall was short enough for the top of the trees to brush against the edges of it. In some cases, it even seemed like certain parts of the jungle tried to reach over it. There was one place where the trees had been burned to the ground though, and that was the small portion of the city that was closest to the shore. It was impossible to tell why it had been burnt down though, as they were still too far away.

The second, inner wall was much bigger than the outer one and seemed to divide the city in several parts, most likely segregating the different classes. Upon further inspection, the city was most likely made up of four or more parts. On both sides, outside the inner walls, were the only parts where the wall opened up to the sea. These open areas had much smaller and modest buildings, along with a sizeable harbor where many ships were anchored. These small, open towns had walls covering the northern part of them, which is why Robin assumed there were more than three parts. You have the inner city, the two small, port towns on the sides and then the unknown area behind them.

"Oi! If it isn't Robin. About time you showed up, you're missing all the fun!" Franky cheered, pulling Robin right out of her thoughts.

"Robin!?" Sanji almost fell into the water as he flailed from the good news.

"Look at that." Robin pointed towards a specific part of the island, completely ignored Sanji whom was currently spinning all around her, cleansing his mind with her beauty.

"What do you guys think it is?" Usopp asked, staring red river running into the sea.

"No shitty clue, most likely some kind of toxic waste from the city." Sanji replied as he walked back to the rest of the crew.

"That's a very specific guess." Franky pointed out.

"Yeah, well I have had some experiences of those things in North Blue." Sanji explained.

"It's really weird how it's pooling up… It almost looks like the substance is rising from the water and forming a film on the surface." Chopper said.

"Maybe there's something in the jungle that's causing this. A plant of some kind, perhaps?" Usopp guessed.

"Who cares… it's most likely nothing important." Zoro yawned as he lied down on the grass. "Wake me up when we get there…" Zoro mumbled before going back to sleep.

Nami, who had been recuperating from their fun a few moments earlier, had finally washed up and was currently putting on some clothes. She was readying herself to join the crew in whatever the fuzz was about. She looked in the mirror and blushed; she was wearing a rather small, revealing bikini top and mini-skirt that ended just below her firm rear. Nami was normally okay with this type of clothing, but Robin had insisted that she made some personal touches for her.

It wasn't the small bikini, or the short skirt that had her blushing so much. It was the fact that she wasn't allowed to wear anything underneath. Nami slowly raised the skirt which had vertical folds so it could be extended and lifted without the slightest bit of effort. "Robin is such a pervert…" she muttered to herself and sighed as she saw her pussy appear in the mirror. She turned around and only bent over a little, but even that was enough to flaunt her sex for anyone who stood behind her. Nami returned to her normal stance and calmed calm before sneaking out of the room.

Just as Nami had stepped out into the open, she could feel the soft breeze of the wind caress her exposed vagina; it sent shivers through her body and caused a tiny moan to escape her lips. She was quite thankful that the wind wasn't that strong today, but she had a suspicion that Robin already knew that. "She wouldn't make me do this unless it was safe." Nami reassured herself. Of course, Nami wouldn't have objected either way, she secretly loved the idea of being readily available for whenever Robin wanted to have fun.

"Hello, everyone!" Nami greeted the crew.

"NAMI-SWAAAAAAN! Finally I'm graced by the sweet comforts of your endless love!" Sanji swooned.

"Woah, that's big city!" Nami stepped to the side, dodging Sanji who came flying towards her.

"Isn't it!? You can smell it too right!?" Luffy exclaimed.

"Smell what?" Nami looked a bit confused.

"Eeeeeeeeeh? Are you stupid or something? The smell of adventure, of course!"

*SMACK* "you're lucky we're not on land yet or I would've buried you where you stand." Nami growled, raising her fist for another swing.

Nami let out a small sigh at the dead lump of captain beneath her. Damn that idiot for making her exert herself, she was tired as it was. She quickly recovered from the incident and saw Robin looking right at her with hungry eyes. She froze in place as the intense gaze from the archeologist undressed her. Ever since Robin ate that first Rumble Ball, she had never really been satisfied, not even if they fucked like bunnies for hours. Robin always came back for more, as if they hadn't done it for days.

Robin began walking towards her and she immediately felt a tingle inside. Nami bit her lip and felt her cheeks turn red as the predator slowly closed in on her. Many wonderful images popped into her mind as she started fantasizing about what Robin would do to her next. Her pussy became moist with all the lewd imagines in her mind, and her nipples grew erect, creating cute little hills on bikini top. A few seconds later, Robin stood in front of her with a sinister smile on her face.

"Have you done as I asked?" Robin whispered.

"Of course." Nami replied. "

Robin didn't say anything, she only inched herself closer and positioned herself behind Nami and hugged her, pressing her breasts against her back. She lowered her right hand traced her fingers against her skin before sliding them inside of her skirt. Nami reflexively took a single step to the side, spreading her legs just a bit. Robin grinned and pressed her hand against Nami's wet sex. "Good girl…" Robin whispered into her ears as she began playing with her button.

Nami jumped slightly and moaned as the exploring fingers had just found her sensitive clitoris. Robin curled her fingers around it, sliding them back and forth, giving Nami a light massage. "She so fucking good…!" Nami thought. She arched her back, pressing herself backwards and spread her legs a bit more, just to give Robin more space to work. The rest of the crew were all too busy to notice what the two girls were up to, which gave Robin the chance to get a little bit more aggressive.

Nami suddenly felt Robin nibble on her ear, which caused her face to make a delicious expression. Robin just stood there as her fingers picked up the pace, rubbing and sliding all over Nami's wet pussy. It was then that Nami sensed something weird. Robin had taken her hand out of her skirt, but she could still feel a hand pressing against her cunt. "Oh no… You wouldn't dare…" Nami thought to herself.

Just as she had realized what was going on, the hand that had grown just above her clit started rubbing its fingers between her lips. As if that wasn't enough, Robin had also summoned a mouth on the palm of said hand. Nami moaned softly as the mouth began to suck and lick her clit. She tried so very hard to be quiet, but Robin didn't make that easy. "Try your best to not get spotted, my toy." Robin whispered. "Or maybe it would turn you if we showed everyone how perverted you are?"

"That was mean, Nami-swan!" Sanji pouted as he pulled himself out of the hole in the wall that he had created. "Hugging!? LET ME JOIN!" Sanji cheered as he spun towards the two.

"Eeh!?" Nami's heart jumped as the chef approached them from behind.

"Have fun now…" Robin whispered as she released her arms around Nami. "You taste great, by the way." She grinned, licking the juice off of her fingers.

Nami closed her legs and tried to look as normal as she could, even though the blush on her face was still present. Sanji halted just behind her, his eyes had already turned into hearts. "Stupid Robin…" she thought as the hand between her legs continued to suck and lick on her sensitive bud. Just as Nami was about to get her act together and greet the chef, a row of tongues grew from the hand, on top of each other, and slid their way into her.

"Aah!" Nami moaned as the tongues spun and coiled around inside of her.

"Are you okay, Nami!?" Sanji asked. "Are you hurt somewhere!?"

"A-Ah… S-Sanji-kun…" Nami's voice trembled as she turned around to face him. "I-I think I j-just have to… sneeze!"

"Oh no, you're not getting sick are you!?" Sanji eyes widened as the memories of the events on Drum Kingdom flooded into his brain. "CHOPPER! NAMI IS SI…" *SMACK* The back of Sanji's head flung backwards and hit the deck with a bang. "Auch…"

"Don't suddenly start screaming like that!" Nami roared.

"Are you okay Nami?" Chopper asked, he was wondering what was going on.

"Oh n-nothing, Chopper! Sanji's just being a worry-wart. E-Everything's fine!" Nami laughed very awkwardly, resisting the urge to moan.

"If you say so…" Chopper scratched his head. Humans are weird sometimes.

Nami groaned as the hand sped up, licking, sucking and tonguing her with increased vigor. It wasn't long before Robin's creation would have her cumming in front of everyone. She had to get out of there before that happened, otherwise they would find out what was going on. Nami thought as hard as she could, but the tongues in her pussy made that very hard. "Just escape somewhere, it doesn't matter where!" Her mind screamed.

"Aaah ha ha ha… haaah!" I just remembered that I have to go to the bathroom!" Nami chuckled like a dork before sprinting towards the bathroom, causing her skirt to lift itself just slightly as she ran.

"N-Nami-Swan…?" Sanji blinked rapidly. "Did I just see what I think I saw…?"

Nami rushed as fast as she could with Robin's hand between her legs. Her knees were getting weak from the pleasure coursing through her body. She gasped as the mouth increased the strength at which it sucked and licked her clit. The tongues moved in and out of her pussy, folding and swirling inside of her. Nami reached the door to the bathroom, but her orgasm was already approaching. She fumbled with the knob as the pleasure welled up inside of her. Just as she finally got it open, her sex tensed up and her orgasm shot through her body.

Almost falling into the room, Nami placed her hand against her mouth to muffle her moans. She closed the door behind her just as her legs failed her. Nami stumbled and fell to her knees as the hand forced her to cum. "Oooh fuck, I'm cumming so hard!" Nami's mind screamed. Her pussy was gushing all over Robin's hand as its tongues dug deep inside of her. She held her hand against her mouth as hard as she could, otherwise her cries of pleasure would surely be heard by her friends.

Even as her orgasm seemed to die down, the hand continued to work tirelessly. "Fuck… I'm so sensitive! We just fucked less than an hour ago… I'm going to lose my mind at this rate!" Nami whimpered into her hand, her second orgasm was approaching. It was then that she realized that she hadn't locked the door behind her. The thought of being discovered with her wet cunt so lewdly on display was the last push she needed.

Nami came once again, moaning as hard as she could into her muffling hand. Her sex throbbed as the intense pleasure made her spasm all over. Her knees jerked as she lifted her ass up from the floor, aiming it towards the door behind her. Anyone who opened the door would see her presenting herself with her tits pressing against the floor and her pussy cumming right in front of them. She moaned and gasped as the fantasies of being discovered fuelled her orgasm.

In the midst of her moment of sexual bliss, footsteps could be heard approached the bathroom. Nami's eyes shot open as they grew louder and louder. "Who is it!?" she thought. "Maybe it's Sanji who was worried about her? Maybe it was Chopper, or maybe even Luffy? They wouldn't just open the door without knocking first, right!?" Nami's heart was racing as her mind processed the situation. She knew that she had to hide, or at least get her quivering sex out of sight before the door opened. But at the same time, she wanted to be caught and show whomever it was how much of a horny slut she was. Her mind was divided.

Suddenly, the door to the bathroom was swung open. Nami cried out into her hand as she came for a third time. "Oh god, they can see my pussy!" she thought to herself. The shadow of the person loomed over her body and it was impossible to tell who it was. All Nami could think about was how fucking good it felt between her legs. Her arousal quickly took over and crushed her worries; she removed her hand that was covering her mouth and straightened her legs. Nami just stood there with her legs apart and her arms resting against the floor, holding her steady as she came her brains out.

"Oh my…" The voice spoke. "Aren't you turning into quite the exhibitionist?"

"Aaa ah haaah…" Nami whimpered, the hand between her legs had vanished, allowing her quivering pussy to be clearly visible to the person behind her.

"I told the others that I was going to check if you were alright." The person stepped into the room and closed the door. "I think it's fair to say that you are feeling much better than just alright. Isn't that right, Nami?"

"Y-You… are s-such a… pervert, R-Robin…" Nami moaned, wiggling her ass at Robin.

"Fufufu… You're such a hypocrite, Nami. You love this just as much as I do." *SMACK* Robin slapped the palm of her hand against Nami's left butt-cheek.

"Aaah!" Nami yelped as the impact of the hand caused her sex to tingle with joy.

"We still got about five minutes before we reach the island, so we should probably get you all sorted out before anyone suspects anything." Robin grinned, staring at the moist, quivering cunt in front of her.

While Robin and Nami had been busy fooling around behind everyone's backs, the ship had closed in on the island and its big city. As they came closer, the crew saw a large sign in the water saying "Pirates to the right" with an arrow indicating the direction. Luffy immediately ordered the ship to be docked at the designated zone which, to everyone's surprise, was no problem at all. The city dealt with pirates all the time and marines were not allowed there unless there was good reason for it. This was of great convenience to the crew. Franky could finally restock and upgrade the Sunny with all the supplies he wanted and Sanji wouldn't have to drag around food across half the island.

The whole gang was super excited for many different reasons. Franky, Sanji and Chopper were going to get supplies and make sure the Sunny was protected at all times. Zoro, Ussop and Brook were tasked with keeping an eye on Luffy, just so he wouldn't get lost while exploring the island. Once Robin and Nami had finished their business in the bathroom, they decided investigate the city itself and see if they could find anything interesting; and maybe even get some new clothes at the same time.

"Shishishi… We're off! Take care of the Sunny while we're gone!" Luffy yelled as jumped off the ship and quickly ran off.

"Oi, wait for us, Luffy!" Usopp yelled.

"Make sure you don't lose Zoro in the jungle, Luffy!" Sanji shouted; his hands were shaking as he placed a cigarette in his mouth.

"MIND YOUR OWN BUSINESS, CURLY-BROW!" Zoro screamed as he tried to catch up to Luffy.

"Well, that's them off. Should we get going as well?" Robin smiled at Nami.

"Right!" Nami responded in a happy tone, she had such a satisfied grin on her face.

"You two ladies enjoy yourself now, you hear." Sanji spoke. He sounded a bit proud for some reason.

"Thank you, Sanji-kun. We will!" Nami cheered.

"Luffy and the rest will probably not be back until tomorrow, so we'll see if there are any nice hotels we can spend the night in…" Robin winked. "so no need to stay up and wait for us."

Both girls giggled as they left the ship and walked towards the western town. Despite having just left, Robin picked up a rumble ball for her backpack and waved it in front of Nami. She had a devilish grin on her face and just as they got out of view of their ship, Robin bit into the ball. Nami watched as Robin licked her lips after swallowing the contents of the ball.

"A-already? And here in the open..?" Nami asked; she was getting a bit nervous.

"Oh it is never too soon, my dear Nami. Besides, I've always wanted to try this…" Robin grinned, slowly crossing her arms.
