Work Text:

The Straw Hats had been fighting for for what seemed like days, but could have only realistically been a few hours, against several fully equipped Marine warships.

They were on a beach off to the side of a small island in the middle of absolutely nowhere, only having stopped there for a few patch up supplies and some food.

They had returned back to the beach where they left the Sunny, only to find her surrounded by Marine warships. Luffy had cursed himself inwardly, he knew they should have left someone on the ship but the island was uninhabited so he hadn't thought it would be necessary. Plus they had needed all the hands they had to help carry all the food back with them.

Now they were in the middle of a massive fight against a seemingly endless army of Marines with nowhere to go.

Nami and Robin were back to back, electrocuting and breaking the bones of waves after waves of Marines that seemed to pour from the ship in a never ending ocean of swords and guns.

Zoro was rushing through, helping to cut down a large portion of the group the girls were fighting, hoping to dwindle the numbers of the bigger groups first before going after the Captains that were there.

Sanji had the same idea, picking Marines off one by one and sending some flying deep into the woods of the island and some into the sea. Usopp was on a hill further back on the island hitting Marines with explosions from a distance, Chopper hiding behind him, not able to do much thanks to the length of the fight and the fact that his Rumble Balls only lasted about three minutes.

Franky was gunning down anyone unfortunate enough to happen to be in his range, sending a wall of bullets into a massive crowd of Marines that had just departed from one of the warships.

All this left Luffy by himself, on a slightly further away bit of the beach, allowing him to freely fight the Captains of each of the several Navy ships. They had apparently come together and decided the best way to get rid of Straw Hat Luffy was to gang up on him and attack as a group.

After many hours of fighting, Luffy had managed to take down all but one of the Captians, adrenaline was rushing hot through his veins as he turned to face the final Captain, a wild grin pulling at his features.

Luffy was panting too hard to call out his attacks at this point, just wildly swinging as he had taken out the final few guys, packing as much force behind the punches as he physically could. He could feel his heart beating out of his chest with excursion, body running probably a little too hot considering he was currently still fighting.

Luffy swings his fist at the final Captain but the man dodges and charges at him and manages to tackle him to the ground. A grunt is forced from Luffy's throat as the Marine Captain slams him hard into the ground, making blood rush though his body with a barely contained gasp.

Luffy just grins wider, laughing wildly as he punches the man hard in the jaw, not even using his Devil Fruit at this point, the Marine Captajn far to close for him to use any of his proper moves.

The Marine hits back hard, harder than Luffy thinks he should be able to considering how the guy is kind of scrawny looking, but the Pirate just grins even wider and laughs just a little louder at the idea that this guy will actually be a good fight. He pulls his legs to his chest and plants his feet on the Marines chest and kicks, hard, sending the Marine flying back several feet.

The man barely gets the opportunity to register that he even moved before Luffy is pouncing on top of him and slamming his fist into the side of the guys face.

The man hits back again and Luffy's mouth floods with metallic flavour. Blood. The Marine must have some kind of spiked metal on his knuckles under those gloves to draw blood.

Luffy doesn't get the chance to check the damage to his face that he can feel as he grins, skin splitting around the cut, before the Marine is launching another punch.

He hits again, this time to Luffy's chest, making the him wheeze out a cough as he slams his knee into the man's chest and hits him into the nose, a weird shiver of delight running through his body at the sickening crack that fills the air.

It's been so long since he fought someone properly like this, he can't even remember the last time he got into a good old fashioned fist fight. Luffy knows his crew can handle themselves, and this is proven by the screaming of Marines getting quieter as less of them remain standing, struck down by the Straw Hats.

The Marine Captains movements turn sluggish when Luffy hits him hard in the face again, watching as the man's eyes roll and go white for a moment before he pulls himself back into the fight, not that he's able to do much anymore.

Luffy feels almost disappointed that the fight is going to be over so quickly and actually finds himself pulling his punches slightly so the man can get a few more good hits in on him and shove Luffy off of his body and into the sand.

Luffy grunts again as he rolls a couple feet away, watching as the Marine staggers to his feet before raising his fist in the air, now gloveless. Luffy watches with fascination as the Marines hand ripples with a grey shimmer before turning fully metallic as spikes grow from his knuckles. Some kind of Devil Fruit power.

Luffy wonders for a moment why the man didn't use this move sooner, must be new to him, but instead just laughs again as the man charges at him. Luffy dodges the attack easily, but doesn't expect the man to turn around so fast and punch him hard in the stomach. Luffy coughs out a mouthfull of blood and cackles, launching himself at the man full speed and headbutting him in the chest.

The man chokes and staggers back as Luffy wipes at his mouth, feeling his blood smear across his cheek with the action.

"You- You're crazy!" The Marine shouts, barely dodging Luffys next attack and that just makes Luffy launch at him again with a wild look in his eye. Luffy had been so caught up in the fight, he doesn't even notice the lack of noise coming from further down the beach and the telltale sound of footsteps in the sand.

Luffy laughs again, louder, it's been so long since he's let himself let go like this, to just fight without his Devil Fruit.

It feels freeing in a weird way, to just be able to fight without worrying about any special attacks. His eyes rake over the Marine in front of him, pinned to the ground, and it feels good to know he did it without his Devil Fruit.

The Marine punches and shoves but Luffy just pushes harder at the man's shoulder until he lets out a scream and Luffy feels the muscles give with a crunch under his hands. He barks out a laugh at this and allows the Marine to scramble up and back a few feet away on his working arm.

Luffy can feel the adrenaline in his body pulsing far too hot under his skin, making his entire body feel tight with energy, but pays it no mind, instead he stalks towards the Marine with a dark look in his eyes.

The Marine looks up at him eyes widening with shock, then disgust, then fear as his eyes travel up Luffy's body.

"You're a freak!" The man shouts again and Luffy wants nothing more than to shut him up for good. It takes the Pirate maybe just a bit to long to figure out what the man is referring to, a little too long to realise why the heat under his skin is almost suffocating.

Luffy stalks forward and kicks the man as hard as he can in the head with a yell, sending the Marine flying into the woods behind him.

Luffy notes with satisfaction that the man is completely unconscious, slumped against a tree trunk a good thirty feet away. He barks out another laugh at wipes at his face again, getting a bit more of the blood off this time, but still smearing what remains over his cheek.

Luffy just stands for a while, panting heavily, blood pumping quick and hot under his skin. His mind is suddenly thrown back to the Marine calling him a freak as he feels his cock throbs hard in his shorts. He almost doubles over, eyes wide with shock at his body's own reaction to the wild adrenaline of the fight, making his blood pump faster than ever.

It's not the first time he's had this reaction in a fight, when he really gets loose and his fight reflex quickly progresses into a demand, but it is the first time it's happened in a while, hence the shock.

What really startles him though is the quiet, almost cautious, call of his name from behind him.

"Luffy?" His head whips around, very careful to not turn his body as he easily recognises the voice of Nami. His eyes are met with the entirety of his crew standing there, faces twisted in expressions of concern and trepidation.

"H-hey guys!" Luffy calls, clearing his throat when his voice catches, smile still wild and taking up majority of his face.

"Captain." Zoro greets easily, although slightly cautious, and Luffy barely manages to hide his shudder as the swordsman addresses him. "Got a bit carried away did we?"

Luffy flushes and turns away slightly, looking back to the man he sent flying, covered in blood and bruises. He winces slightly, wide grin faltering to a small smile as he realises the amount of damage he actually did to the poor Marine Captain.

This does not, however, calm the adrenaline rushing through his blood, pumping hot under his skin. Nor does it stop his cock from twitching at the lack of stimulation it's recieveing. He's still panting heavily when he speaks again.

"You guys head back to the ship, I'll join you in a second. Just gotta take care of something really quick." Luffys says with a bright smile, pulling his hands in front of himself to try and hide the way they're shaking as he turns away from his crew.

He gets a couple hesitant murmurs of agreement from them before he begins to hear their receding footsteps on the sand. When he can't hear them walking anymore, he quickly begins to walk towards the forest on shaky legs. In his rush to leave, he fails to notice the crewmember that remained to keep an eye on him.

Luffy pushes his way through the trees, breathing heavily before slumping back against a large tree trunk, hand immediately finding it's way to the front of his shorts. He lets out a gasp as he palms himself, letting his head fall back against the tree as he moans into the air. He quickly brings a hand up to his mouth and bites down on his knuckle to try and keep quiet as he grinds the heel of his hand into his throbbing cock.

He doubles over at the sensation, the adrenaline from the fight still pulsing through him making the feeling just that much better. Luffy's hips rock up on instinct, his heartbeat loud in his ears as he throws his head to the side with a gasp, already close. He doesn't hear the approaching footsteps to the side of him.

All of a sudden there's a hand on his shoulder and a voice whispering low in his ear.

"Hey Captian." Luffy rips his hand away from himself with a whine and looks towards the voice of Zoro

"Got a little worked up from the fight, did we?"
The swordsman asks teasingly, only a few inches away from his face. Luffy swallows thickly, eyes darting back and forth between Zoro's scarred eye and his open eye as he begins to stutter out an excuse.

"I-I didn't- I don't- Shut up!" Luffy flushes, hiding his face behind his hands and wishing Zoro would dissappear when he opened his eyes.

Unfortunately, Zoro was still there when Luffy opened his eyes, sporting a shit eating grin and looking at him with something deeper in his eye.

Really then, this seems more fortunate than unfortunate, as Zoro steps closer and Luffy's breath hitches on an inhale, letting Zoro get as close as he wants.

Luffy doesn't actually want to push Zoro away. He's worked up from the fight and his objectively very attractive first mate is practically throwing himself at him.

He isn't stupid enough to walk away from this.

Zoro's hands find Luffy's hips, squeezing teasingly and tugging him forward a little.

Luffy's breath hitches, eyes wide and pupils blown as Zoro presses their hips together. Eyes flicking up, Luffy exhales shakily, shooting Zoro a look that asks if he's sure.

Zoro's expression softens and he nods, prompting Luffy to move and Luffy has never been one to hesitate.

He pushes his hips forward, grinding against Zoro with a low moan, his hands finding Zoro's shoulders and gripping tightly.

The groan Zoro lets out at that will fuel Luffy's fantasies for years to come and it only prompts him to do it again, a little harder.

The two quickly settle into a rhythm, Luffy grinding forward, head falling to Zoro's shoulder and his hips twitching desperately, cock throbbing as he nears that tantalising edge once more. Zoro presses forward responsively, gasping his pleasure into Luffy's ear as his hands tighten on his hips.

"Zoro..." Luffy moans, low and breathy as he slides his hands down Zoro's back to his hips to tug the other man forward, grinding their cocks together again even through layers of clothing.

"Captian.." Zoro gasps in response and oh- heat sparks in Luffy's gut at that, hands tightening on Zoro's hips as he ruts forward seeking that maddening friction between them.

It doesn't take long after that for Luffy to fall over the edge into pleasure, letting Zoro roll their hips together and work him through what might be one of the best orgasms he's ever had.

Bodies still pressed close and Zoro still hard and aching against him, Luffy leans forward to crash his lips to Zoro's.

It's all teeth and spit and Luffy thinks he may have been a bit too rough because he can taste the metallic tang of blood on his tongue, but Zoro just moans and pushes closer, licking into Luffy's mouth like he's chasing the coppery flavour of it.

Luffy lets his tongue meet Zoro's with no hesitation, licking over his teeth and gums, heat flaring in his abdomen when Zoro groans and his hips stutter forwards, knees going weak as he cums in his pants against Luffy's thigh.

The kiss slows until Zoro is pulling back, a wet string of saliva connecting their lips before snapping. They're both panting and Luffy isn't quite sure what to do now, eyes flicking to Zoro's in question.

Zoro just sighs softly, a mischievous smile on his face as he pecks another kiss to Luffy's lips before leaning close to his ear and whispering low. "Want you to fuck me."

Luffy shudders, letting his head fall back against the tree behind him as Zoro starts to kiss along the column of his neck, licking and biting and working Luffy up in all the right ways.

Nodding eagerly, Luffy runs a hand through Zoro's hair and tugs, pulling him back so their eyes can meet before kissing him again and switching their positions, slamming Zoro's back to the tree and assaulting his mouth with his own.

Zoro moans enthusiastically, arms wrapping around Luffy's neck to pull him closer as Luffy's hands find his hips and squeeze playfully.

"Turn around." Luffy whispers low and hot against Zoro's lips before very reluctantly breaking the kiss. Zoro obeys without thinking, turning so his front is pressed to the tree now and leaving his back exposed, a surefire symbol of trust that Luffy does not miss as he runs his hands reverently up Zoro's sides and to his ribs, hands slipping under Zoro's shirt to do so.

"Off." Is Luffy's next command as his hands slip back down to the waistband of Zoro's trousers, hands tugging impatiently. Zoro quickly moves to help, popping the button on the front and helping to pull them past his hips, underwear coming with until they're a pool of fabric at his feet and his lower half is left bare and exposed for Luffy's pleasure.

Zoro gasps as Luffy pressed flush to his back, trailing a hand up Zoro's clothed chest to his neck, pausing for hand a second to squeeze lightly in a way that has a whine bursting from Zoro's lips before he can stop it. The hand continues up to press insistently to Zoro's lips.

Without thinking, Zoro opens his lips easily, letting Luffy's fingers slip into the wet cavern of his mouth. Luffy hums his approval and Zoro's knees go weak at the sound as Luffy's fingers press deeper, running over his tongue and gathering as much saliva as he can up on the two digits.

Belatedly, Zoro realises what Luffy is doing and closes his mouth around his fingers, licking over them and wetting them as much as he can, moaning maybe a little to enthusiastically all considering.

Luffy starts to press burning open-mouthed kisses to the back of Zoro's neck, sucking at the slightly sweaty skin and reveling in the way Zoro shudders and moans around his fingers.

Just to test the waters, Luffy angles his wrist a little and pushes his fingers deep into Zoro's mouth.

The gag that sounds between them has Luffy's shuddering around a groan and Zoro honest to God whimpering, albeit muffled, at the feeling.

Pulling his fingers from Zoro's mouth, Luffy presses another series of kisses to the back of Zoro's neck, wet and hot as he trails his hand down Zoro's body to squeeze at his hips once more before using his non spit slick hand to spread Zoro open a little more, kicking lightly at Zoro's ankle with his foot to encourage him to spread his legs more.

Zoro moves obediently, widening his stance so Luffy has better access, drool dripping down his chin from Luffy carelessly fucking his fingers into his mouth. Zoro shifts, pressing back against Luffy and making a small breathless noise as he arches his back slightly, leaning his arms against the tree in front of him.

Unabashed, Zoro presents himself to his Captain without any hesitation or thought. If he had spared it a moment, even began to think about the position he's actually put himself in, he would be burning red with embarrassment.

But as it is, Zoro just moans and wiggles his hips to entice Luffy to get on with it, no shame or hesitation, just the desperate desire for Luffy to hurry the fuck up and ruin him already.

Groaning, Luffy presses one of his spit slick fingers to Zoro's hole, rubbing over it and listening with a grin as Zoro whines, pushing his hips into the touch wantonly.

Luffy presses with his finger, soothing a hand over Zoro's ass to encourage him to relax, whispering sweet words of encouragement that have Zoro's cock twitching and leaking onto the dirt below as he moans shamelessly.

When Zoro finally relaxes enough for the tip of Luffy's finger to slip inside, he moans. It's a weird feeling, being stretched open for the first time, but it's a welcome one nonetheless. That, however, may be mostly due to the fact that it's Luffy who's doing it.

Zoro hums, eyebrows furrowing as he adjusts to the strange feeling, leaning his forehead against his arms as he arches his back further.

Luffy presses deeper, slowly but surely working his finger into Zoro, the tight heat around him is otherworldly and he can't even begin to imagine how it would feel around his cock.

Letting out a soft exhale, Zoro presses his hips back again, the sensation of Luffy's finger inside him feeling a little less weird and a little more like it could feel good, really good.

"Luffy... Another, please..." Zoro moans, hands clenching into fists where they're pressed to the tree in front of him. Luffy kisses his confirmation to the back of Zoro's neck and carefully presses another finger to Zoro's hole, rubbing along the sensitive skin.

Zoro whines, mouth falling open because fuck, that stretch is more than he thought it would be. The feeling of a second finger pressing into him has him gasping and shifting his hips, not quite sure if he's trying to push closer or pull away from the weird feeling.

Slowly, carefully, Luffy works his second finger inside, the stretch not quite burning but not exactly comfortable either. Zoro hums out a whine, body instinctively trying to get more, as if the promise of pleasure is just a little further.

Now with two fingers settled nicely inside Zoro's heat, Luffy has a little more room to maneuver them and he sets to work with single minded determination, carefully pulling his fingers halfway out before pushing them back in again, letting Zoro adjust to the feeling.

Luffy also shifts his wrist to get a better angle and curls his fingers just barely against Zoro's inner walls, searching and pressing.

Zoro gasps suddenly, body instinctively arching towards the small wave of pleasure he just felt as Luffy curled his fingers.

"Again. Fuck, again." Zoro moans, eyes slipping shut as pleasure starts to roll in waves through his gut. Luffy just grins, pressing against that spot again and watching with glee as Zoro arches futher into it, a low moan escaping his lips.

"Feel good?" Luffy asks, voice low and teasing in Zoro's ear, like he already knows the answer, but just wants to hear Zoro say it.

"Yeah... fuck s'good.." Zoro slurs, head dipping between his shoulders as Luffy doesn't let up, pressing on what Zoro knows is his prostate over and over again.

The pleasure in Zoro's gut ramps up and up, spreading slow like a wildfire through his body. The stretch of Luffy's fingers feels so good now, where it had just felt strange earlier, and the gentle push and pull of those fingers fucking in and out of him only adds to that raging heat.

Zoro shudders, cock twitching almost violently and leaking onto the dirt below as the pleasure continues to build up and up, burning in his abdomen.

Zoro realises belatedly that he's about to cum, everything burning so hot and building slowly but steadily inside him. It feels different to the usual build up to his orgasms, slow and firm instead of quick and sharp.

"Cumming! Fuck fuck! Oh fuck!" Zoro barley has time to warn before everything is washing over him at once.

His whole body trembles and shakes as he moans, gasps, whines, and whimpers loudly, mouth dropping open and eyes rolling back as they slip shut. It's different, so different, and so, so good. Zoro can feel his cock twitching and leaking something that doesn't quite feel like the usual release steadily, pulsing with his racing heart.

And it just keeps going, and going, and going as Luffy continues to press and rub at Zoro's prostate. Eventually, Zoro has to grab at Luffy's wrist to stop him, everything so overwhelming as his body shakes and trembles with the aftershocks of pleasure.

Luffy chuckles as he pulls his fingers out, pressing soothing kisses to the back of Zoro's neck and whispering sweet words of praise in his ear. Zoro just shudders, brain effectively mush in his head as it rushes to process everything that just happened.

"Still with me?" Luffy says, squeezing a hand on Zoro's hip. Nodding shakily, Zoro takes a deep breath, before speaking.

"Holy shit, Luff..." Zoro breathes, looking down to where he's still hard and throbbing. He pants, turning his head to look over his shoulder, eyes watery and drool pooling at the corner of his mouth. He looks messy, ruined. Luffy grins.

"You look good." Luffy says, leaning over Zoro's body to kiss him, licking the spit from Zoro's lips and chin. Zoro moans into the kiss, still panting heavily, breath stolen from his lungs by greedy lips and tongue.

Luffy huffs out a small laugh as Zoro whines and pushes back, grinding against him. Luffy breaks the kiss, spitting onto his hand and slicking his cock with it, pushing forward and pressing the head of his cock to Zoro's hole.

Zoro keens, pressing back eagerly, and it makes Luffy's head spin with desire as he shoves forward, breath catching and stuttering as Zoro moans brokenly.

There's still a base level thrum of adrenaline coursing through Luffy's blood as he pushes all the way in, pressing his forehead to Zoro's sboulderblades and moaning as he sinks fully into Zoro's body.

He starts a mindless rhythm, thrusting into Zoro with single-minded determination as he wraps a hand around the others cock.

Luffy's close already, having seen Zoro fall apart like that by his hands had worked him right up to the hights of arousal as he slams into Zoro's boy over and over again, basking in the broken, punched out moans he's recieveing in response.

"Fuck. How are you still so tight?" Luffy grits out as he fucks in harder, hand moving faster, bulling Zoro straight through the overstimulation and headfirst into more blinding pleasure as Zoro cries out, tears falling down his cheeks from the sheer pleasure alone.

It doesn't take long for them both to cum, Zoro for thr second time in five minutes. It's quick and slippy and desperate but God if it isn't the best thing they've ever felt as white hot pleasure washes over them simultaneously.

Luffy thrusts hard, pressing as deep as he can before stilling with a grunt and cumming inside Zoro's mind melting warmth.

Zoro gasps, crying out and half collapsing. He would be on the ground if it weren't for Luffy's and suddenly around his middle as the pleasure of his orgasm blinds him for a moment.

Luffy is panting hard, face pressed to Zoro's spine between his shoulder blades as he carefully pulls out, watching his release drip out of Zoro for a moment before flipping the other man around on the tree trunk so they're facing each other.

Zoro grins lazily, limp with the aftereffects of his orgasm, and wraps his arms around Luffy's neck to drag him into a kiss.

Luffy reciprocates quickly, easily, like he's been doing it his whole life. It's slow and gentle compared to earlier and both of them are beaming into it, smiling so wide it's barely a kiss anymore.

"We should get back. The others are gonna get worried." Luffy huffs out eventually, pulling back to sort his clothes out and brush of the dirt that had gathered on the fabric.

Zoro hums out a small laugh, nodding as he fixes himself up, trying to ignore the face he can still feel Luffy's cum inside him. He's going to need a shower as soon as possible.

"You gonna keep getting worked up this much after every fight?" Zoro asks playfully as they start to walk back, grinning over at Luffy who flushes with a sheepish smile.

"I don't know. It kinda just happens." He defends weakly, blinks his gaze away from Zoro's direction.

Huffing out a laugh, Zoro leans close enough to whisper in Luffy's ear. "If it ever happens again, don't hesitate to find me. I can help... work you back down.." Zoro says with a grin as the Sunny comes into view, stuffing his hands into his pockets and continuing to walk with a laugh as Luffy stands there frozen for a moment before following with a matching grin.

Luffy turns to Zoro, his right hand man, his swordsman, his first mate, and smiles.

"You've got a deal."
