Nami jerks awake, fingers clutching at the rough material she's utilizing as a blanket. She stares into the darkness, heart racing in her chest, and listens. No sound comes to her ears but the gentle lapping of water against the hull, and she's starting to think that her sleeping mind imagined it, but she rises anyway because she'd rather be mistaken and safe than neglectful and dead.

She moves quickly and quietly as she edges to the cabin's window, because after spending so many years dealing with Arlong's crew and those she victimizes, she's learned that stealth will do far more than reckless bravado to keep her alive.

The moon is extremely bright tonight, raising reflections on the water, and she's forced to shield her eyes as she squints through the glass at the silhouettes outlined in the small boat floating next to hers. Part of the amorphous blob is immediately recognizable as the weapons carried by the swordsman, and she's starting to relax again - because she'll happily let him deal with whatever's going on instead of risking her own neck - when the shadowy shape distorts and there's another muffled cry, similar to the one that woke her.

"I told you to be quiet!"

Nami's instantly awake. She eases to the doorway, grateful that she left the door hanging open because no squeaking hinges will give her away, and peers outside.

Roronoa Zoro stands in the other boat with their captain trapped securely against his bare chest, his hold pinning the smaller pirate's arms to his sides. The fingers of one hand are wedged in Luffy's mouth, stifling his indignant cries, and the other is shoved down the front of his shorts. The swordsman's grinding his hips against his victim's rear and snarling threats as Luffy twists in his grasp forcefully enough to make him stagger and rock the boat.

Horrified, Nami bursts onto the deck, determined to put a stop to the abuse even though she has no idea what exactly she's going to do. "What the hell are you doing? LET HIM GO!"

The startled swordsman shoves Luffy away from him so forcefully that they both nearly go overboard, and the captain yelps in surprise as he's slammed directly into the mast and bounces off. He lands near Zoro's feet and huddles there, wide-eyed and whimpering.

"Luffy, get over here!" Nami demands, extending a hand across the gap between the vessels. "I won't let him touch you again!"

"It's not what it looks like! He asked for it!" Zoro blurts, torn between going for his swords and diving overboard and swimming for it, because the navigator's glare looks capable of boiling water or possibly even imploding testicles.

"Don't blame him because you're a pervert!" Nami roars back, her eyes locked on Luffy, who looks as though he's about to burst into tears. She's furious with Zoro for taking advantage of the younger pirate and even more upset that she missed the warning signs. "NOW, LUFFY!"

"Listen, you stupid-"

"ZORRRRO!"

"No, Luffy, get away from him!"

Ignoring Nami's frantically waving hand, the captain rockets to his feet and lunges at Zoro, grabbing the swordsman by the neck with both hands and shaking him violently.

Zoro doesn't fight back, to Nami's relief and satisfaction, maybe because the bastard knows he deserves whatever beating Luffy intends to give him now that someone finally knows what he's been through and since he's decided to stand up for himself. He's shouting in the swordsman's face now and punctuating each word with a good hard shake.

"Why'd Zoro stop? I was gonna come!"

Wait, what? The triumphant expression on Nami's face fades, replaced by a blank stare.

"Grrrk!" Zoro protests, clawing at the fingers on his neck. "'Cause I don't want a fucking audience!"

"But I waited all day!"

"I told you to be more quiet! You're too goddamn noisy!"

"Zoro's noisy too!"

"Like hell I am!"

"Zoro yells a lot when I-"

"If you'd just stop fucking laughing when you-"

Nami turns on her heel and walks back into the cabin, since they've obviously forgotten that she's been standing there listening as they make it vividly clear that she's been rather mistaken about the exact nature of their relationship.

As she shakes out her blanket and wraps it around her shoulders, she hears Zoro cursing outside, shouting at Luffy for ripping the button off his trousers. There's a brief struggle, then a loud splash, followed by a loud exclamation of "OH SHIT!" and considerable additional splashing. Then more screeching, which is abruptly cut short.

For a moment she's convinced that they've knocked each other unconscious and she can just go back to sleep and forget this whole thing ever happened, but then there's a low, throaty moan. The burst of giggles that follows can only be Luffy, and Nami stares blearily at the ceiling and wonders how long it'll be until morning.

"We're gonna need a bigger boat."
