Zoro loves Sanji but Sanji has been dating Luffy for months now. When arriving at a strange island, both Zoro and Luffy found a strange lake and accidently fell in it, making the both of them switch bodies. How will Luffy and Zoro will handle that especially, when no one else can know, not even Sanji?

I love music and movies so you will see some phrases belonging to a song or a movie here and there being said by the characters.

Don't own One Piece if I did, everyone would be after Sanji

CHAPTER 1: The Lake

They say to you that it will go away, that you will find someone else, someone better, that it was just a crush or that there is someone for everyone. They will say to you that that person was not meant for you, they will say anything to you to make you feel better, perhaps they are right, but Zoro knows deep in his heart that none of this explanations or excuses will suffice. He'd met the love of his life and because of his stupidity, he lost it. He was so cocky thinking that no one will take him away from him, he underestimated him…not intentionally of course, but Zoro just thought that him being a little crazy, having this weird attitude towards women and having a short temper, no one would pay him any attention or at least take him seriously.

Zoro assumed he was the only one able to see behind that façade, the only one to notice, how caring he is…always jeopardizing his life for the people he cares about, how elegant, intelligent and interesting he truly is. How he looks so happy while cooking or talking about cooking, how drop dead gorgeous he is, having a great build, long legs, creamy skin, shiny golden hair, deep blue eyes and a breathtaking smile. Not that he is used to seeing his smile, at least not directed at him. Before, it was really strange to see the cook smile and not just for him…for anyone…but around four months ago, that changed...now, that beautiful smile is often given to his lover…their captain.

Yes, his best friend, his captain took the only person he ever wanted from him…not on purpose of course. Luffy nor Sanji knows about his feelings towards the cook and who would? He only insults, yells at and fights with him…no one can know…and even less now that Sanji is taken…

Four months ago everything was ok, until one day at dinner, Luffy asked, no, demanded that Sanji go on a date with him, startling everyone with his sudden request and the crew almost fainted when Sanji agreed.

At first, Zoro thought that Luffy was no threat, come on, the kid must think that on a date, you should only talk, eat and that's it. But oh, did Luffy teach him otherwise.

Not only did Luffy take the cook to a fancy place, (yes, he was spying on them) he also paid for dinner, walked with Sanji around the beach where he confessed to Sanji and kissed him passionately. And to top it all off, on their way back and before each went to their respective rooms, he gave Sanji a present. It was a nice pocket watch, the one that the cook was looking for for a long time.

How could he have seen that one coming? The kid is oblivious to everything and all of the sudden he is a pro at dating, confessing and wooing? And besides why, why his cook? Why not Nami or Robin or Usopp or, or?

Just anyone but his only love.

Now, Zoro must stand Luffy embracing his cook, Luffy kissing his cook, Luffy making love to his cook, yes…Zoro's known for a long time now that the couple took that step already, having heard the cook gasping and moaning Luffy's name one night in the crow's nest….Luffy's name.

Zoro thought that since Luffy and Sanji's official announcement of going out, only the first months would be hell, that eventually his feelings for him would vanish, that later, he would be able to watch them and not feel jealously and pain, but it didn't go away, it got worse…

His discomfort didn't go unnoticed by some members of the crew, however. Nami, Usopp, Franky and Robin eventually noticed his looks directed at the cook, his pain when he sees them together, and his attitude every time Luffy touches the cook in front of him…but what could they do? Nothing…

A few hours later…

"LAAAND!"

The yell snapped Zoro out of his thoughts and moved to see what was going on.

"Ok, guys, listen, this island is dangerous. No one knows what you can come across, so be careful and listen to me well. We need food, so you are going in groups. Robin, Sanji and I will stay on the ship, Brook, Franky and Chopper will go together and Usopp, Zoro and Luffy. Don't you dare cause any trouble and I am talking specifically to you, Luffy." Nami said.

"Awwww…but I wanted to explore the island with Sanji!"

Nami ignored Luffy's whining and kept threatening the crew.

Later on in a strange forest…

"Zoro! Over here, move! Zoroooo!"

"Luffy, chill. I'm coming, I'm coming…" 'Why me?'

Luffy stood in front of a lake that was a strange purple color.

"Look, look, the water's purple, how awesome!"

Zoro stood next to Luffy, observing the lake…'It is purple, how strange…'

"Zoro, let's get inside…you can help me swim!"

"What?! No way in hell, it could be poison!"

"Aww, come oooon!"

Luffy didn't wait for a reply, he just grabbed Zoro's shirt and pulled him forward, making him lose his balance and fall into the lake. Zoro can't see around him, not even his own hands, and soon, he realized that he is running oxygen, so he swam up to the surface. It's not that deep so he can stand up in it. Zoro started to call for Luffy, not finding him anywhere, as he yelled, he also noticed that his voice sounded strange. After a few seconds, Zoro watched something emerge from the water. Zoro was expecting Luffy to reappear but instead, he found himself facing…well…at another version of himself.

"This water is awesome!" Luffy yelled.

"Luffy, get out, get out!" Zoro yelled, panicking.

Luffy, for once, did as he was told and got out from the lake.

"Zoro, what happened, what did you see? And why do I sound like you?"

Zoro can't believe this, in front of him is him, but with Luffy's personality. More panic arose and Zoro quickly went to the lake to look his reflection in the water and he almost screamed. Looking at his reflection is him, but from what it looks like, he seems to be inside Luffy's body.

"Wow, you look just like me, Zoro."

"Idiot! And you look like me, so, it must be the lake. It must have changed our bodies somehow." 'What to do, what to do?'

"Luffy, we need to get to the ship and inform Chopper about this!"

"No, you can't do that!" said a voice behind them.

Both Luffy and Zoro turned around to face an old guy.

"What did you just say, grandpa? And where the hell did you come from?" Zoro asked.

"I live here, and you must know that if others find out about this, your chances of getting back to your own body will be zero. This lake has a curse. You are stuck in each other's bodies for at least two months."

"What? But why can't we tell anyone?"

"Like I told you, son, this lake is cursed. Nothing too bad, but no one really knows what could happen if you touch the water. I have seen people turn into animals, come out with more body parts…well, let's say that you guys are lucky. The curse will vanish eventually, but the trick is to make sure that no one notices the change or the curse won't be broken."

Both Luffy and Zoro looked at each other…it's so weird to be facing a copy or, more accurately, at yourself, but how are they going to manage that? Can they even pretend for that long without anyone noticing their strange behavior? Even more, if they are under attack…can Zoro use Luffy's elasticity and Luffy his strength and swords?

"Hey, old man, do we gain also the other's abilities?" Zoro asked.

"Well, yeah, everything the other has, agility, strength, intelligence would belong to you now…"

Zoro can't believe this and Luffy haven't said a word…he must be concerned…

"Luffy, don't worry, we can manag-"

"Wooo! How awesome! Zoro, give me your swords, I wanna try them!"

Unbelievable…their captain ladies and gentlemen…

"Luffy, aren't you worried?"

Luffy looked at Zoro and smiled.

"Why? It's only for a couple of months, it'll be fun! I can get to see what it's like to be Demon Hunter Roronoa Zoro!"

Well, Luffy is right, they just need to be cautious so that no one else notices and everything will be fine.

"Hey, old man, are you sure it's just for a few…what?"

The old man disappeared. 'Great…just fuckin' great…'

"Luffy, let's go and find Usopp, he must be worried. And remember, act like me, you idiot or everyone will notice and I don't want to be stuck in your body forever…"

"Ok! Don't worry Zoro…I know you…I just need to be grumpy, call Nami a witch, sleep a lot, drink a lot of booze and fight a lot with….Sanji…" Luffy stopped moving and if Zoro was right, he looks concerned…

"Luffy what is it?" Zoro asked

"Zoro…what about Sanji?"

"Huh? What about him? Oh…" Zoro understood what Luffy is talking about now. Luffy, being Zoro now, means he can't act as Sanji's boyfriend. Which means…. Zoro knows he is being selfish but he is really excited, being Luffy means he will be able to be closer to the cook…

Zoro is turning red. 'Does this mean that I have to kiss the cook, embrace him and, and…s-sleep with him?!' Zoro was about to get a nosebleed. He knows, he knows he shouldn't be thinking that way about his best friend's boyfriend but it's too much for him…he has wanted Sanji for a long time…

"Zoro…I got one rule and one rule only…" Luffy spoke up suddenly.

"What? A rule?" 'Luffy sounds serious now…'

"Yes, while you are me…don't you dare touch Sanji…"

Both stayed in silence, staring at each other.

"Luffy…then what should I do if he wants to kiss me, or hug me or stuff like that?"

Luffy thought about that for a moment and then he sighed a defeated breath…

"This sucks…Well, I guess any of those are necessary, but don't sleep with him ok?"

Wow, who would think Luffy is so possessive about his cook? But Zoro can relate to that, if it were him dating the cook and something like this happened, he would be threatening anyone who dared to even put a finger on the cook. 'Well, I guess I can do that…'

"S-Sure thing, captain…"

They headed to the ship, looking for Usopp along the way…Zoro glanced at his captain…he looks so sad now…and now Zoro feels bad because he is...not…

"Guys…over here!"

Both Luffy and Zoro turned to look at Usopp coming towards them.

"Guys, where did you go? I was looking both of you everywhere…"

And the acting begins…

"It was awesome, we came across some weird looking plants and suddenly, a big bird chased us!" Zoro said, acting the same way Luffy would.

"Aww guys, why didn't you wait for me….well, anyway, a found some fruits, so we can go back to the ship now…" Usopp.

Back on the Sunny…

"Ok, guys, good work, this will be enough until we reach another island. Luffy, can you give all this food to Sanji? He's in the kitchen…" Nami said

Zoro looked back at Luffy, waiting for his approval, Luffy just nodded his head…but he is still not ok with it.

Zoro took the bags and entered the kitchen.

There he is, the cook in all his glory, Zoro just stood there, watching Sanji move. God he is gorgeous, and Sanji is moving everywhere inside the kitchen, the aroma was all around the ship already, Zoro took a look at Sanji's face, he is smiling and humming…yes, Zoro is completely in love…damn.

"Oh Luffy…you guys came back already." Sanji said, coming up to Zoro.

"A-Ah, yeah…sorry, I just came here because Nami sent me. Here's some fruits and vegetables…"

Sanji just chuckled.

"Luffy, you know very well that I don't mind if it is you."

'Damn, Zoro, calm down, you're Luffy now, be more bright be happier…'

"Luffy what's wrong?" Sanji asked, worried.

"Nothing, love-cook." 'Oh, shit'

"Luffy, why are you calling me that?"

"Ah, sorry, I guess I spend too much time with Zoro".

"It's that fuckin' marimo talking shit about me to you?!" Sanji asked.

"What? No, no, we...were talking about food because we were hungry and you came up in the conversation…h-he would never talk bad about you…"

"Tch! Right…" Sanji dropped the subject and stared at Zoro.

Sanji approached Zoro and whispered seductively. "So, are you still hungry? Because I can give you your dessert first…" And with that, Sanji kissed him passionately.

Zoro froze at first but then relaxed, besides Luffy said it was ok to kiss the cook. Zoro embraced Sanji and deepened the kiss. Sanji tasted amazing, not at all at cigarettes; he tasted sweet.

Zoro couldn't care less for Luffy right now, right now he can only think of how hot Sanji is and how the hell Sanji managed to get these amazing muscles, and how full and firm his ass feels. Zoro got aroused quickly, the longing making him desperate. Zoro forced Sanji against the wall and began touching Sanji's firm abdomen, deepening the kiss and using his tongue this time. Zoro couldn't take it so he began dry humping Sanji, making said man moan. Zoro wanted this for a long time and feeling both of their clothed erections create friction is too much for him to handle.

"L-Luffy!" Sanji moaned again.

It's not his name, it's not his fucking name or his body, but he can't stop. He's about to break the only rule Luffy made him follow, the only one he must promise to keep.

"Mmm, L-Luffy…not…n-not here." Sanji begged.

"S-Sanji please, please, I need you right now…it's been too damn long."

Sanji chuckled. "What are you talking about? We just did it this morning."

Jealously is what Zoro felt at Sanji's statement. He is touching his best friend's lover and he is the one jealous, he doesn't have the right to feel that way, Sanji doesn't belong to him…but he can't help it.

"Even so, I need you right now…" Zoro replied huskily, guiding his hand to touch Sanji's clothed package as Zoro began to caress Sanji's bulge…

"A-Ah hah, Luffy, s-so good!"

"Mmm, S-sanji. God, you're amazing!"

Zoro can't take it, he needs this to go further, he needs Sanji now. When Zoro was about to remove his and Sanji's pants, Nami called out to them…

They both stopped their actions, and just focused on regaining their breath.

"Hah…talk about bad timing." Sanji said.

"Yeah, fucking witch…" Zoro muttered.

"Hey, don't talk about Nami like that! You're spending way too much time with the marimo. Don't catch his bad manners."

"Sorry."

"Don't worry." Sanji placed a quick kiss on his lips. "Tonight we can continue this…"

And with that, Sanji went outside the kitchen.

Zoro stood there for a while and smiled but then his smile dropped. He can't do this, he so desperately wants to but he can't. He could lose Luffy's friendship. This is going to be harder than he originally thought, not even a few hours later and he already jumped the cook. This is bad, he needs to stay calm and collected these few months, and besides he can do this…right? Right?

Hi! I hope it was not too confusing, just keep in mind that Zoro has Luffy's body and vice-versa.

So…comments are much appreciated. What do you think?
