Supportive

Zoro could not be having a worse day. He was woken up up from his nap to see the Thousand Sunny caught in some kind of mega storm. He had to risk his life to save Robin who fell from the ship, and how does the world reward him for that selfless act? He wakes up on some island buck naked with that very same woman! The older woman saw it all, including Zoro's little secret She was currently laughing at the situation.

"Stop laughing woman!" Zoro angrily shouted, but his tough guy act probably served to make him look more hilarious. Robin finally spoke after calming down "hehe, I'm sorry but this was just so unexpected! I didn't expect to wake up to see you so...unadorned. Seeing you stand so proudly like that made me laugh!". "Yeah I bet this all really hilarious! So just keep laughing it up!" Zoro shouted. Robin's face is no longer smiling, she has a more neutral expression. "I'm really am sorry for laughing at you Zoro. I'm not trying to make you feel bad about yourself."

"I've spent years training to get my body to where it now, all that gets undermined when someone sees- well that." Zoro grumbles. "Aww Zoro, is that why you are always so grumpy? It's nothing to be ashamed about!" Robin says. Zoro shakes his head. "You know what others would say, like that damn cook if he could see me now."

Zoro isn't necessarily wrong in his assumption. The former pirate hunter turned member of the Straw Hats crew, was feared by many. He had a large bounty to go with his infamy. But most of that could be undermined if any were to see his small peen. Most might laugh and make fun of him.

Nico Robin however, was not one of those people. She doesn't see Zoro's little peen as something amusing, but actually finds it kinda cute. She has a secret love for cute things like bunnies and kitten, but Zoro's penis might be one of the most adorable things she's seen! Like a little flower bud that hasn't bloomed yet. It's not like she had a particular preference in 'sizes', she had been hit on my many men. Pirates loves to flaunt the large size of their penises around, Robin frankly finds that behavior gross. So seeing such a powerful man like Zoro have such a lack of endowment is weirdly making him seem more enticing in Robin's eyes...

"Zoro-*wince* can you help me up?" Robin winced as she tried to sit up. Zora bends down and helps Robin up. "Mmm, what a gentleman..." Robin giggled. Zoro just grumbles and helps walk Robin to a tree. She can now properly sit up. Zoro sits on a nearby rock, facing away from Robin. "Don't keep making fun of me." Zoro grumbles. "Zoro-" Robin sounds disappointed. "I'm serious Zoro, you are one of toughest and most reserved man I’ve ever known. It shocks me more that you would let something as petty as this bother you. If you expect me to mock you than you don't know me. I actually find it kinda cute…”

Zoro turned his head. “What?” Zoro said raising his eyebrow. “Oh nothing!” Robin responded with a chuckle. With some difficulty she leaned over to pat him on the back in reassurance. She is able to feel the muscles on Zoro's back, she can see the deep scars he suffered from the years. It complements his broad shoulders and muscles, clearly he is a man who's been to hell and back training his body to what it is now. Not to mention those glutes...

Robin blushed and giggled to herself. She needed to stop herself because she was starting to get some dirty thoughts. "What are you giggling about now?" said Zoro. "Nothing! Maybe I just need some rest." said Robin.

"Well go get some sleep so you can recover your strength. I'll keep watch." Zoro said. Robin smiled and obliged, she liked how chivalrous Zoro is being. He created a makeshift bed and shelter out of leaves of bamboo for the night.
