Prompt: Frobin, Robin fingerpaints on Franky (the pictures she paints are up to you)
The sun was shining and there was no cloud to be seen. Everything was peaceful and the Thousand Sunny floated on the wide ocean.
The crew was distributed all around the ship, trying to fight the heat in their own ways.
Chopper was somewhere in the depths of the ship together with Brook where it was the coolest, while Luffy was lying on his favourite seat not moving at all. Zoro was hiding in shadows, trying to sleep and Sanji disappeared into the kitchen to make drinks for his lovely ladies.
Robin was lying under a beach umbrella installed on the deck, reading a book while the remaining members went swimming. She could hear the voices of Nami, Usopp and Franky and it sounded like they had a lot of fun.
But as the sun was shining without any merci, it didn't last long. Nami climbed up on the ship, complaining loudly about how she would get a sunburn if she didn't put on any suncream. "You should put on some of it too!" she told the two men who were playing with her in the water just moments ago."Or we aren't going to play in the water anymore!" Both didn't look very happy about the idea, but obeyed anyway. Especially Usopp lacked the strength to talk back due to the heat.
"Franky, do you want me to apply the cream on your back?" Robin, who had watched the scene asked.
"That would be SUPER!" the cyborg shouted, making his trademark-pose, in response. He would have trouble to apply it on that part himself.
The blue-haired man sat on the lounger next to Robin, facing her with his back.
She started to apply the creme, putting on a relatively big amount at once by accident. Looking at it, an idea struck her.
"What are you doing?" Franky asked after after a moment.
He heard a chuckle from behind himself. "Nothing."
"That isn't nothing. Wait- is that the Sunny?" he asked surprised.
"That's SUUUPER!" he shouted out, jumping up to do his pose once again.
"Robin? Why did you paint the Thousand Sunny on Franky's back?" Nami asked, an amused look on her face.
