Happy Birthday Luffy~!

お誕生日おめでとうルフィ~!

Luffy sat on the Thousand Sunny with his head pointing towards the sky and to the backside of the ship. The wind was calm and his straw hat fluttered against his back like a butterfly. The sails battered as the wind caught in them. Waves splashed along the sides of the boat creating an oceanic symphony.

Although this sounded like one of those peaceful moments, there was a gigantic red mark across Luffy's cheek and was swelling every second. The captain accidently charged into the kitchen receiving a kick and punch from his beloved cook and navigator. It was a usual routine Luffy did in the morning but today he was strictly not allowed in the place Luffy loved the most in the whole Thousand Sunny. The captain sulked and curled his legs close to his body but he should have known this would've happened. Today wasn't like any other day, it was his birthday.

Luffy stroked the sensitive cheek as he continued to stare at the sky, more particularly the sails. He soon heard footsteps and he peered down to see how it was. It was his first mate, Roronoa Zoro, with his usual stoic appearance, a little hint of tiredness.

The captain asked as he slapped his hands against his knees, "Is breakfast ready?"

Zoro looked up and there was a look on the swordsman's face as if he didn't understand the question. A second later though, he replied, "Not yet I guess."

"Hmm…" Luffy forced himself not to sound disappointed but his stomach told otherwise. Zoro smirked at the noise almost like the roar of a lion and leaned against the railing. The swordsman closed his eyes to listen to the ocean when he heard his captain's voice, "Did you do that?"

Zoro didn't even need to look, "Yeah."

"What is it?"

"It's a koinobori. In my hometown we put them on flagpoles. Today's Kodomo no Hi, the day we honor children."

"What do you do on…Kodomo no Hi?"

"Well, we hang those and then eat some kashiwa rice cakes. The ones Sensei made were the best."

"Kashiwa?" Luffy's stomach growled cheerfully, "Do you think Sanji can make those?"

"Maybe."

Luffy hummed out a reply and gazed at the fluttering objects placed along a thick rope from his jolly roger to the stern of the ship. There were ten flags in total; nine of them were shaped like fish. Each one had an individual color: red, green, orange, brown, dark blue, pink, purple, light blue, and black. The tenth one which was the first one in line was just colorful strips. All looked like they were swimming in the beautiful blue sky. Since there were so many of these gigantic flags, the ship was swaying a bit wildly to the side. Luffy grinned at the green one with green and shiny golden scales over its large body.

"Is that you?"

Zoro finally turned to where Luffy was looking and nodded.

"Did you make all of them?"

"No," Zoro said honestly, "Usopp helped with some of the sewing and Franky made the rope that connects all of the koinobori."

Luffy contemplated over what Zoro had said and suddenly he pouted, "I'm not a kid!"

"Ha?" Zoro raised an eye, "What are you talking about?"

Luffy hit his chest proudly, "I'm seventeen!"

"I know that." Zoro snickered and leaned further to pat Luffy's hair, "But you're more like a brat." The captain's face blushed from the gentle affection and flung his eyes back to the koinobori. He loved all of the kois but he loved his the best. It was red with white and blue scales. On one of the eyes there was a scar identical to his. It seemed to swim powerfully compared to the others. He had to laugh with the one with the dark blue scales. Although it was swimming between the brown and the pink fish, the tail constantly thrashed against the green one and brushed gently over the orange and purple.

"So is this my birthday present?"

"…crap."

Luffy shot a dumbfounded look at the swordsman. Zoro's mouth was wide open and quickly covered his hand to hide his surprise.

"Wait…did you-"

Zoro slapped his hand over his forehead, "No wonder the kitchen's off limits…and breakfast isn't ready…"

Luffy's eyes went white. "You forgot my birthday?"

Zoro shot out a hand, "I-I'm sorry! It…it slipped out of my mind!"

"It-?" Luffy threw his hands up in the air and dramatically collapsed on the lion's head, losing all functions in the body like an octopus. He wriggled his finger in small circles, "You remembered Kodomo no Hi but not mine-I…I feel…I feel…" the captain sulked and continued to draw sloppy circles on the wooden surface.

"Ah…Luffy…" Zoro sheepishly scratched the back of his head. He stepped on the rail and climbed onto the lion's head, "Luffy, I-"

A hand grabbed his shirt collar and Zoro was pulled down, his lips forcefully slammed against the captain's. He winced at the impact since their teeth were knocked together. He parted his lips to lick away the burning feeling from the collision but Luffy's tongue entered, invading his mouth cavern.

Today Zoro tasted of morning breath, which doesn't sound very pleasant but it was Zoro and Zoro always tasted good no matter what. Luffy explored through every nook and cranny of Zoro, touching his tongue against the other until they were out of breath. Luffy broke first and frowned, his lower lip jutted up. Zoro brushed away the saliva that trailed down the curve of his jaw and raised his eyes toward his captain. There was a dark blush on the swordsman's face either from shame that he forgot his lover's birthday or from the sudden kiss.

Luffy nodded his head toward the sailing fish, "I'm still going to consider that as one of my birthday presents but I still want something from you." He was suddenly grinning like a little devil, "Since you don't have anything ready for me you can just offer yourself to me!"

Zoro scoffed, "You are such a spoiled brat you know that?"

There was a muffled shout from the kitchen and the door flew open. All of his crew mates popped out and raised their arms gesturing him, "It's ready birthday boy!"

"Come on Luffy." Zoro turned to leave when Luffy took a hold of his arm, keeping him still.

Luffy snickered joyfully and brushed his lips, gently this time, across Zoro's ear, "I'm not going to let you sleep tonight." The young captain licked the inner shell of the swordsman's earlobe before leaping off the lion head. With his keen senses he could smell what usually served during dinnertime.

He felt much better; the wound on his cheek felt like a scratch.

The End

For those who thought this might continue I apologize but it is not. All birthday stories are one-shots.

Japanese Lesson:
Kodomo no Hi
The translation is Children's Day. It's usually for to celebrate the health and happiness of boys but recently it is celebrated through both genders. Small note, there is a day to celebrate specifically girls (March 3).

Kashiwa Mochi- Kashiwa Rice cakes. I never ate one before but I think it has anko (red bean paste) inside. The distinctive trait is that the Kashiwa mocha has an oak leaf wrapped around it.
