The Fourth Sword (Zoro x Luffy) LEMON YAOI *One Shot*

The Fourth Sword

A/N: Hey! This is my very first lemon...so it's probably going to be bad but...I tried at least! Enjoy!

It was one of those relaxed days on the Thousand Sunny, and the crew was just lounging around and enjoying the pleasant day. Nami, was sunbathing while eating a tangerine, Robin sat beside her reading one of her history books as usual, Sanji attended to the lady's while bringing them refreshing drinks and desserts, Usopp was fishing with Chopper, Franky was making sure the sunny didn't need any repairs, Brook was playing a soft, smooth melody that suited the mood, Zoro was in the crow's nest training, and their idiotic captain was sitting on top of the Sunnys lion figurehead, staring out at the ocean.

Luffy fell onto his back out of boredom and yelled, "I'M BORED! THIS IS BORING!" The crew, minus Robin, jumped slightly as someone broke the silence after a few hours.

"Well Luffy, if you're really that bored...GO PLAY WITH FRANKY!" yelled Nami as she sat up, in a furious mood. Luffy sat up and spun around to face the rest of his crew and yelled, "I. DON'T. WANNA!" Everyone was shocked...yes, even Robin. Luffy was always talking about how cool Franky's new weapons and his new body was. Infact, his eyes even sparkled when he just thought about what Franky might surprise him with.

"Well then...um, come fish with Usopp and me!" yelled Chopper as he stood up. Luffy furrowed his brows into a thin crease and shook his head in a choppy manner. Everyone was starting to get slightly worried, Luffy never turned down the chance to hang out with his cool cyborg friend Franky....and he certainly never passed up the chance to go swimming with his best friends.

"Luffy, do ya want me to make you some food then?" asked Sanji.

'If he says no....then something is defi-' Sanji's thoughts were interrupted when Luffy quickly said a firm, "NO." Chopper gasped and hopped onto the Sunnys' thick green grass shouting, "AH! WE NEED A DOCTOR! LUFFY'S SICK! WAIT! I'M THE DOCTOR!" Chopper quickly ran up to Luffy, transforming into his human form. He felt his forehead and studied him.

"This is...strange." said Chopper as he backed away to get a full view of his straw-hatted captain.

"What is it Chopper? Is Luffy really sick?"asked Usopp as he turned around on the railing facing Chopper.

"N-No he isn't. That's what's strange." Chopper said as he started to panic a little. 'Is Luffy sick and I'm not a good enough doctor to find it? Has he come down with an incurable disease like Doctor did? Is he gonna die!?' Choppers mind was racing when Luffy finally spoke up, "Guys I feel fine...I'm just not hungry." Everyone was still wide-eyed trying to point out his lie. Luffy wasn't lying. He is a very bad liar, so if he was...then they would be able to figure it out. Robin, being the observant person she is, quickly looked him over, and smiled a very faint smile.

"Oh, Captain-san." Robin said in her soft voice looking up from her book.

"Ne? What is it Robin?" asked Luffy as he tilted his head to the side.

"I forgot something in the crow's nest...would you mind grabbing it for me Captain-san?" she asked smiling a bit bigger now. Luffy gladly accepted her request and ran up to the crow's nest. At the time, Luffy never thought about the fact that...Robin can make extra limbs grow...she could've grabbed whatever she left with her ability not having to move. He also didn't think about how she never said exactly what she forgot. As Luffy disappeared, Robin chuckled softly.

"Eh? Robin what was all that about? Couldn't you have gotten it yourself?" asked Nami, as she pulled her long tangerine colored locks into a ponytail so they wouldn't be in the way.
