Chapter Text
Law is crawling out of his skin after two days on the water to Dressrosa. He thinks he hides it fairly well, at the big family style meals that Sanji insists on no one bats an eye at him. Still, the stress is written into every line of his body, a restless revenge that weighs on him at all hours. Luffy doesn’t help. His unflinching optimism, the plainness of their alliance and their insane plan all seem simple to him, an equation that will always end with him coming out on top.
Or if he doesn’t, at least he died trying. Law doesn’t know if Luffy has ever thought about death in any real way, and he doesn’t intend to ask.
He knows that if he skipped mealtimes, Sanji probably wouldn’t let him starve, but he still obeys by his kitchen rule and slinks out of his makeshift cabin at least twice a day. Sanji’s food is worth watching Luffy chew with his mouth open and Zoro try to drink himself into an early grave. Then, he sulks back to his cabin—a small room adjacent to their shared sleeping quarters with a cot haphazardly shoved inside—and stews on what’s ahead of them.
Two days into their long journey, Law might go insane before he gets the chance to rip Doflamingo’s head off his shoulders. He swallows back the shot of adrenaline that results from the image and rolls off his lumpy mattress. He’s been pacing the tiny space for the last forty-eight hours without any relief. He needs a bath. Maybe a drink and some decent company.
Good company is scarce on the Thousand Sunny, but Nami showed him to the baths on his first night, telling him they take shifts in the mornings. He tugs open the door to his cabin. Above him, it sounds like a normal day is in full swing, with all the Strawhats killing time on the top deck. Law shoves his hands in his pockets and heads to the baths.
He doesn’t bump into anyone on the way to the baths, and the cacophony from up above fades as he steps into the small adjoining chamber. Steam has seeped beneath the second door, making the small locker room damp and warm. There’s a stack of clean towels on a low bench, and Law assumes he won’t be joining anyone considering there aren’t any clothes piled up on the bench. He breathes a sigh of relief and starts stripping. The thought of having to make pathetic small talk while trying to wash off the events on Punk Hazard makes Law feel ill. He folds his clothing, sets it in a neat little pile, drapes a towel over his shoulder, and pushes through the inner door to the baths.
A wall of steam hits him, making the air silky and hot as he breathes in. Already, some of his nervous energy is seeping out of him. The heat works through his skin and into his muscles, making him slump as he wanders around the edge of the large pool. He rakes a hand through his dampening hair and peers through the steam, watching it swirl off the top of the water. It’s peaceful, almost hypnotic—
The world bursts into bright white sound as something launches out of the bath. Law only barely swallows down a screech of shock as he stumbles back over the wet tiles. Water sloshes over the edge of the pool and slaps at the edges of it, rattling his thoughts into unintelligible mush as the source of the sound finally pushes through the steam.
The facts come to Law in short, confused bursts. Familiar laughter. Dark hair. Luffy. Naked. Dripping with water. Law surveys him without meaning to, trying to make sense of the cacophony of noise, why Luffy is even here—
He’s still laughing as he says, “I got you good didn’t I! Couldn’t help it, haven’t seen you in a while and had to mess with you a bit.” Law doesn’t bother to remind him that he saw him last night at dinner, all possible words drying up on his tongue as he takes every shining inch of him in.
Luffy’s wet hair curls at his ears and temples. There are a few suds still lingering at the crown of his head where he didn’t wash out his shampoo before ambushing Law. His eyes are bright and excited and he’s still chattering, but Law can only pick out three or so words in each long sentence. Luffy looks smaller naked. His shoulders are narrow, his chest and arms are toned but lithe. If Law hadn’t repeatedly seen the proof of his strength, he couldn’t imagine this body holding so much power. The scar across his chest is dark against his flushed warm skin and Law’s eyes follow the long points of it to the slight curve of Luffy’s hips.
Law’s eyes almost bulge out of his head. Beneath the soft curve of Luffy’s belly is… a cunt. If possible, time slows even further, the world narrowing down to Law’s heartbeat in his ears as he gawks openly. Luffy is so unabashed in his nakedness, still talking and still not covering his pussy. Law bites the inside of his cheek hard, but it still isn’t enough to snap him out of his reverie. Not when Luffy’s thick thighs are squeezed together, making his pussy look even chubbier—and he’s shaved. Bare. Water shines on his soft mound and Law’s head spins.
“Uh… Traffy?”
Law swallows hard. He hates when Luffy calls him that. He hates when Luffy calls him that, especially when he’s naked and still not covering himself and Law still can’t look away. “Don’t call me that,” he bites out. But, hearing it once is enough to push his mind right down into the gutter. Heat swirls in his belly, licking at his insides like the steam on his skin as that stupid nickname rings in his ears. He wonders if Luffy would still call him that while Law has him spread out on his cock. Saliva pools under his tongue as fantasies tumble into one another, gaining shape and lust. Luffy bent over for him, on his knees begging for cock, spreading himself—
It takes him a long moment to realize that Luffy has stopped speaking. The sudden silence rings in Law’s ears and he rips his eyes away from Luffy’s body. Everything snaps into sharp contrast as his eyes settle on Luffy’s face—his lips parted and cheeks flushed. The arousal swirling in Law’s body settles hard in his belly, a toe curling ache lancing through his cock. His hard cock. Law stares into Luffy’s face as his eyes slowly drip down the length of Law’s body to settle at his groin.
Law holds his breath. Serves him right to be caught out like this. Maybe Zoro will throw him overboard, he’s always seemed a bit too protective of his captain. A fitting end to him after his filthy thoughts, his sudden desperation to take advantage of Luffy in all the worst ways. He fights the childish urge to cover his groin. The damage has already been done, he might as well bear his punishment with proper stoicism.
But, Luffy just keeps staring at him. Keeps staring at his cock , eyes wide and hot with that furrow still between his brows. He looks confused and something awful in Law twists with disgusting satisfaction. Luffy takes a half step forward, head still bent and Law’s belly flips at the evidence of their height difference. “Why is it… like that?” Luffy asks. His voice is soft, maybe the softest Law has ever heard it, unsure and careful. Law is stunned to silence by it, something in his chest crumpling beneath the weight of his desire.
The space between them is scant now and the heat magnifies until sweat beads at Law’s navel. He swallows hard, knowing he should push Luffy away and is too selfish to go through with it. “It gets… bigger?” His words lift at the end and the naive question is sweeter—dirtier—than Law could have ever imagined.
Luffy lifts his hand. He extends it into the space between them, into the stormy heat stretched between their bodies, reaching for the length of Law’s cock. Desire rips through him, sharp enough to jostle his common sense back into place. He smacks Luffy’s hand away and takes a step back, breaking the spell between them. He grabs onto the rope of his self control and pulls himself back from the edge as he tugs the towel off his shoulder and wraps it tightly around his waist. He resists the urge to flee from the baths completely as Luffy looks up at him.
“What are you doing?” Law snaps. It feels so good to fall back into his normal rhythms, this petty annoyance soothing the prickle of his skin. “You should cover up, you know.”
Luffy frowns and puts his hands on his hips. Instead of the innocent confusion he leveled at Law earlier, he now matches his frustration. “Why would I do that? Nobody else cares.”
Law grinds his teeth and tries to smother the possessiveness that rears its head at Luffy’s words. “Just get back in. Finish up.”
Luffy keeps staring at him, head tilting back and forth as he decides whether or not to listen. Finally, he lifts one shoulder in an easy little shrug and jumps back into the bath. Law watches him disappear into the steam and sighs. His cock is still hard, but he desperately wants a bath. The steam parts and Luffy appears, humming as he scrubs his arms with a rough sponge. It’s as if that moment shared between them was just a dream.
Law swallows, steels himself, discards his towel, and wades into the bath. If Luffy doesn’t care, Law won’t care either. He dunks himself beneath the hot water, hissing at how the sting flushes his skin. He turns his back on Luffy, resolutely ignoring his presence as he grabs a bar of soap and scrubs himself down.
Turning his back on Luffy isn’t enough to banish his filthy thoughts. Not looking at him might even make it worse. Law’s curiosity takes over as he lifts himself out of the tub to scrub his legs. With the image of Luffy’s body burned onto the insides of his eyes, he can imagine the suds rolling down his glistening skin, his long fingered hands running between his pecs, dipping down between his legs to touch himself—
Law dunks himself into the steaming water. His cock throbs. He needs to get out of here. He scrubs his sudsy hands through his hair, rinses, and leaps out of the bath. He almost skids across the wet tile in his rush to grab his towel and escape. He doesn’t pause in the locker room. He cinches his towel around his waist, scoops up his clothes, and barrels through into the hallway. He only lets out the breath he didn’t realize he was holding once he’s back in his makeshift room, back pressed against the shut door as he drops his damp clothes onto the floor next to him.
Of course, his cock is still traitorously hard, and he rips the towel off his hips. The last string in his frayed braid of self control snaps as he wraps a hand around himself. Even that first squeeze around the base is enough to have his head tipping back, strands of wet hair tickling the back of his neck as he lets out a long, wavering breath. The first stroke of his rough hand has his stomach flipping. It’s been so long since he got off, so long since he’s felt this much desire filling up him, threatening to overflow. He twists his palm at the head, catching pre-cum in his palm and spreading it across his length.
It’s easy to close his eyes and conjure Luffy again. That shocked, sweet look on his face, how water made rivers down his chest and thighs, guiding Law’s eyes inexorably to his cunt. His cock kicks in his hand and he bites down on the groans that rumble up his chest and to his throat. His mind can’t settle for long, first catching on how chubby and pink Luffy’s pussy was, before darting to that pinched expression he leveled at him.
His mind tumbles again, scattering in ten different directions at once, picking up filthy bits of latent fantasies and applying them all to Luffy. He would cry so prettily on Law’s cock, those big eyes going glossy before the tears finally spill down his cheeks. Law thinks he’d be a screamer—he’s so loud most of the time anyway, he can’t imagine getting a fat cock in his cunt could make him any quieter. His knees shake as he locks them against the door, raising a hand to cover his mouth as he drags his thumb over the slit of his cockhead.
He’d be squirmy too, twisting and stretching beneath Law’s hands, but never really trying to get away. Law gasps into his palm. He’s dripping now and the slick glide of his hand prickles hot and insistent in his belly. He would make Luffy bend beneath him, even as he cried and whimpered for it, Law would be in control of him, fucking him open until he was squirting around his cock like a bitch. He can almost hear Luffy whining for it, innocence twisting every noise and word into a sharp blade of pleasure.
Law’s orgasm bubbles under his skin, tightening in his balls and making his legs tremble. He strokes himself faster, tighter, trying to ignore the roughness of his palm to imagine Luffy’s hand around him. He’d be on his knees, folded up sweetly at Law’s feet, hand working over his cock, pretty eyes wide as he opened his mouth for Law’s spend. Law would have to prompt him into begging for it—he wouldn’t know what Law wanted—but once he got the idea, he’d be relentless. He’d do whatever he could for Law’s load on his face, in his mouth. Maybe, if Law told him too, he’d even beg Daddy for what he wanted.
“Fuck!” Law barks into the damp cup of his palm, knees buckling as he comes. White spots crawl across his vision and his head goes light as he keeps stroking himself, his orgasm shuddering through him to the tips of his fingers as his cock continues to jerk and drip. He tips forward and catches himself on his elbow, panting as he finally starts to go soft. It takes a long time for the arousal to leak out of him. By the time he rocks back onto his heels, he realizes that’s the best orgasm he can remember having. “Shit,” he mutters.
