Chapter Text
The sun was setting on the calm waters of the Grand Line, casting a warm glow across the deck of the Thousand Sunny. The ship sliced through the waves with the grace of a fin, leaving a wake that shimmered like molten gold. In the quiet solitude of the ship's cabin, Zoro lay on his hanging wooden bunk, tired from training. His breathing was steady, the air cool on his skin, his green coat folded on the floor, his swords neatly sheathed beside him.
On deck, his captain's laughter echoed, a sound as free as the wind that filled their sails. Zoro could feel the vibrations of it through the wood, a gentle reminder of his friend's spirit. He faded in and out of his nap with a smile.
Zoro woke, his instincts honed from years of wild living. But his eye remained closed. He heard the footsteps approaching, the door to the men's quarters creaking open. A shadow fell over him; he knew it was Luffy.
"Hey, Zoro," Luffy called out, his voice a mix of goofy mischief and that unknown quality that even the wisest of men couldn't read. "You've got to see this!"
Zoro sighed and peaked open his eye.
A giant, red dick was right in front of him.
"Look at this HUUUUGE boner!" The young captain's eyes were sparkling.
A beat. A long beat.
"Uh..." Zoro hesitated, at a loss for words.
Sure, Luffy was weird, and Zoro had gotten used to his antics, but this… was a new one.
Of course, when Zoro was a child, he'd seen plenty of the other boys that goofed off with 'sword playing' at the dojo, comparing sizes. And he'd seen plenty of his crewmates' morning wood throughout the time he'd spent with them.
But Luffy always seemed to be an enigma that never dealt with those sort of human problems. And beyond that... no one had ever shoved a rock-hard cock in Zoro's face.
Saying he was thrown for a loop was an understatement.
"It's so BIG!" Luffy exclaimed, his voice a barrel of excitement. The room was filled with the sound of his giggling, which only added to Zoro's befuddlement. Then, in a simple, flat voice, Luffy added, "I don't know what to do with it." A dumb, rubber smile painted the captain's face.
"...You've had that thing for years... and you don't know how to use it?" Zoro asked, bewildered.
"Well, not like this!" Luffy said, his face flushing a shade of red that was almost as vibrant as the band of his straw hat. "It's just... I don't know why, but it won't go down, no matter what I do!" He waved his erection around like a bizarre conductor's baton, the tip smacking into the cabin wall with a muffled thud.
The absurdity of the situation made it difficult for Zoro to maintain his usual stoic facade.
"And why did you come to me with it?" Zoro raised an eyebrow, his voice laden with skepticism.
"Because it's Zoro's job to help me, right?" Luffy replied with the same innocence he used when asking for a piece (truckload) of meat after a long day's work. "Zoro's my right-hand man."
Zoro's brow arched at that. He sat up, eyes stoic. "I see..." He grabbed Wado. "You want me to cut it off?"
Luffy squealed. "N-no, Zoro! Not that! Just... I don't know, do something!"
The swordsman couldn't hold back the laugh at the back of his throat.
"Well, what have you tried, Luffy? If you've already emptied the tank enough times, and it's still up, then there might be something wrong with your body." He gave his captain a nonplussed look, "Did you eat something weird again, Luffy?"
"No!" The rubbery glutton held. "I just ate Sanji's food."
Zoro eyed him, doubt evident, "You sure?" he pressed.
"Yes," his captain's eyes were resolute. No lie there.
Zoro sighed, "Well then you probably need to go to Chopper, something may be--"
"What's 'empty the tank'?" Luffy cut.
"Huh?" the swordsman gaped at his captain, mulling over the magnitude of that idiotic look on his face. "… Jacked off," he clarified. Luffy responded with a tilt of his head. Zoro's eye was wide. "... What have you tried to make it go down?"
"All of the normal stuff!" Luffy huffed. "I waited. Like, forever. I thought about old lady Kokoro. I did cold water..."
Zoro blinked at him.
"… You didn't touch it?"
"Zoro, why would I touch it? That just makes it worse," Luffy chided at his right-hand man. As if the swordsman was the idiot in the room.
"... This is not my problem," Zoro mumbled to himself, turning around in his cot. "You're supposed to rub it until white stuff comes out, Luffy. Then, it'll go down."
Silence.
Luffy wasn't leaving. Behind him, Zoro heard sounds, the ruffling of clothes and skin.
"NOT HERE, YOU IDIOT!!" he yelled, teeth out. "Go to the bathroom," he instructed. "And don't let the girls see it; it's rude," he added, sliding in that additional bit of social knowledge that he himself had belatedly learned.
Luffy whined and walked out of the men's quarters, straw hat over his crotch.
Zoro tried to sleep.
Within 15 minutes, Luffy was back.
"Zoroooo," the childish captain whined.
Zoro grumpily turned around.
Luffy's erection was right by his head, bent in an arc against the wall, looking painfully hard.
"It's not working," the captain continued to whine.
Zoro didn't say anything, face level. He turned back around.
"ZOROOOOO! Heeeelp!" Luffy's voice was now a high-pitched whine as he shook Zoro's shoulder pleadingly.
"I'm not helping with that," the crewmate informed.
"But Zoro's so good with things!" Luffy pressed, his eyes wide with desperation. The swordsman's ear twitched at that. "Zoro's the only one I can count on."
Again, those eyes. Pleading, resolute.
Honest.
Zoro looked to the side. His face felt hot for some reason. "… Fine, I'll show you how," he mumbled.
Luffy's eyes lit up like Christmas morning. He hopped over to Zoro's cot, his erection bobbing like a yo-yo.
The movement bounced Zoro on his bed. He sighed, forehead red has he stared at the giant thing between his captain's thighs. Touching another man's dick is probably a weird thing to do, right? Cuz looking at another man's junk when you pee is bad… How do fathers normally teach their sons? His brain tried to puzzle through these equations in his mind.
Eventually, he settled on the best possible conclusion.
Zoro unzipped his own pants, exposing himself to his captain. "Look, it's simple," he began, his voice gruff. His captain's eyes were transfixed. The swordsman took hold of his own member and started to demonstrate a simple, rhythmic motion. "Just... you know..."
"Zoro's pretty small," the captain noted, voice distant.
"I'm not! You're just huge!" he clarified. "And it's cuz I'm not even hard yet." But he was hard, at least a little bit, his half-chub twitching in his own hand as a reminder.
Luffy shut up and Zoro continued, growing to full hardness as he moved his hand. The swordsman stared resolutely at his blanket. His dick filled out, maybe an inch longer, at best.
"Oh, I see!"
Zoro looked up at that. Luffy nodded enthusiastically, his own hand reaching down to grasp himself.
Zoro's hand moved in a shaky, unpracticed motion that spoke of volumes of how little experience he actually had with the act. A life of living outside and single-minded focus on his swordsmanship hadn't permitted much time for indulgent waste.
Luffy was looking way too excited - that zealous sparkle in his eyes and something else. Again, Zoro averted his gaze, focusing on the wall. He could feel the heat radiating off Luffy's body, and the occasional brush of their legs sent jolts of goosebumps up his skin.
And then, a hand was on his.
“W-what are you doing?!” he gasped. His hand jolted and Luffy's fingers took the opportunity to steal the full grip of Zoro's member.
"This is easier," the captain supplied, breathless. "My body feels weak when I rub my own."
"That's not the POINT, you—" Zoro's waist violently arched as Luffy twisted his hand.
Luffy's eyes went wide and his smile grew. "Wow," he studied his swordsman.
Zoro's face burned redder than blood. He tried to swipe Luffy's hand away, but it was like wrestling a giant octopus. "L-Luffy, s-sto--!"
But Luffy wasn't listening, his eyes glued to the motion of his hand on Zoro's cock, his own neglected dick standing tall and proud as he pumped away far too hard. The room was filled with the sound of skin on wet skin and blankets twisting as Zoro writhed.
"Is it working?" Luffy asked, his voice hopeful, his grip tightening beneath Zoro's hand.
Zoro couldn't reply. He was too busy biting his lower lip, trying not to let out the sounds that were building in his throat. All he could do was hold onto and pull at his captain's stupid rubber hand. He could feel the pressure building, his toes curling into the bed.
Luffy's hand moved faster, his thumb circling the slit of Zoro's cock.
"Ah!" Zoro gasped, his eye jumping to the ceiling. He'd never felt anything like this before, the heat was intense and overwhelming.
He felt his captain's eyes on him, studying his every twitch and reaction with that same curious fascination.
Luffy's hand felt strange - large and powerful, with a bit of a rubbery, supple give.
"I'm g-gonna..." Zoro's voice trailed off, his body tensing.
Luffy tilted his head, his eyes half lidded and as he watched the expressions flit across Zoro's face. "Is white stuff gonna come out?"
The swordsman sobbed at his captain's stupid voice.
The pressure built fast. In seconds, his body was a coil of tension, ready to snap. He felt his release, the warmth spreading through him like a wildfire. His hips jerked upwards, and he let out a strangled cry as Luffy's hand kept moving, the friction sending waves of jolts through him.
Zoro's head thunked back onto the pillow, his hand limp over Luffy's, his chest rising and falling heavily. "G-goddammit, Luffy," he panted.
But the captain was oblivious to his plight, his hand still wrapped around Zoro's now-softening cock, examining it with the same fascination one might reserve for a rare treasure. "It's so smooth," he mused.
He added his other hand to pull Luffy's palm away, but the rubber grip was adamant. "It's over, Luffy," he managed, his voice hoarse.
Luffy's eyes flicked up to meet his, and there was something strange in them. "But I'm not done," Luffy said, his voice a low murmur, his thumb brushing gently against the swordsman's now-sensitive slit.
The touch sent a shock through the entirety of Zoro's body. He tried to sit up; his arms were like jelly. "What do you mean, you're not—"
Luffy's hand squeezed again, and Zoro's words caught in a pained squeal.
"L-Lu— s-sto—" Zoro panted, his chest jumping with every stroke. But Luffy didn't listen. He just kept pumping away, his grip tightening every time Zoro made a noise.
Zoro's body was a live wire, numb but too alive.
"Lu— ...please... I ca... I can't..." Zoro begged, his body a mass of tremors. His vision was watery.
It was at that moment that a miracle occurred. Through the fog and electricity of overstimulation, a lightbulb clicked in Zoro's head. 'But I'm not done.' ...His captain was going to keep jacking Zoro... until Luffy himself came. That was his captain's logic. That was his captain's dumbass brain.
Zoro looked at Luffy's thick, long, twitching thing. It purpled at the tip.
He grabbed it. Luffy's hand on his shaft jumped, pausing its movements.
His captain looked down at his right-hand man's… right hand.
Luffy didn't say anything. He just watched.
Zoro's grip was firm, but unsure, his every limb still shaking from overstimulation.
He looked up at his captain, his eye half-closed in a glower that was lost to his flushed face. He circled his thumb against the slit, the same way Luffy had done to him.
Luffy gasped, the hand on Zoro's cock squeezing tight in response.
Zoro made a noise, a sound caught between pain and something else. But he grit it and pressed on, hand sliding resolutely up and down his captain's monster of a dick.
"Zoro," Luffy's voice was distant, his breathing even heavier now. "… This is… sex... isn't it?"
Zoro's arm stuttered at that. ... Was it?
His mind raced, trying to piece together the scenario and all of his limited knowledge.
"Zoro," Luffy breathed; his expression was different. The swordsman's brows pinched and twitched as he started at his captain.
Without warning, the rubbery pirate was moving. Zoro twisted as his captain tugged off his pants and underwear, the black trousers falling to the floor with a deft thud. Rubbery hands were pushing Zoro's thighs apart. And his captain was looking down at that place that had never been touched by the sun. He didn't know what to do. Luffy's eyes were strange. They stared down at him like he was... meat. He felt hot. The room was tiny. The air twisted like it was full of gas.
He was turned over. His ass was pulled up. He knew what sex looked like; he'd seen dogs. Apparently, Luffy had too.
Something big and hot was pressing into his crack. His face was burning. The squishy, wet head was pressing against his hole.
"W-wait!" Zoro managed to get out, his eye wide.
Luffy didn't hear. He was too caught up in his own world, his face a mask of wonder. Zoro felt the tip of Luffy's cock, warm and pliant, press into his entrance. Luffy's rubbery dick squished its way in.
"Lu—"
With a wet pop, the bulbous head pushed past the rim. The captain stared at the way his right-hand's hole squeezed the meat of his cock, denting the shape of it like a balloon through a tube.
Zoro's eyes watered, his body taut like a bowstring.
The swordsman gasped as his captain's thick shaft slid in deeper, thickening inside; when it hit a sensitive place, he yelped out a noise that didn't sound human. It was a high-pitched squeal, one that seemed to echo in the cabin.
The elasticity allowed for a surprisingly smooth entry. Luffy's dick stretched at the entrance, molding to fit. But past the rim, inside, the rubber bloated to its full size, fighting against the contracting muscles within.
"Zoro," Luffy breathed, voice dizzy,
Zoro's head swam. He breathed through the sensation. It hurt, just a bit. It burned. It filled, slowly.
"Wow," he heard his captain whisper. The smaller man was trembling above him. "Zoro feels so good," Luffy breathed.
The swordsman vibrated and groaned at the burn. At the praise. At the sensation. At the way Luffy sounded; the way he was making Luffy sound. At... he didn't know what.
He wasn't making sense. Nothing was making sense. He was rock-hard and dangling between his own legs.
Luffy kept pushing.
He felt his captain's narrow hips reaching his ass.
The moment Luffy was fully seated, Zoro's neck and face and ears tingled with something odd and deep, his mind hot and feather-light, his head full.
Better than any alcohol.
His breathing was ragged.
It felt so good.
So dizzy.
Luffy's hand was gentle but firm as it slid down Zoro's back, the warmth of it seeping into the swordsman's skin. He leaned in closer, his breath hot on his crewmate's neck. "Zoro" he whispered, his voice a low rumble. The movement pressed those hips deeper, a slow roll.
Zoro made a nose, deep and drunk.
"Captain," he slurred, "Captain... Captain..."
Sound escaped him at each exhale. At each inhale. High. Dazed. So good.
He felt his captain's weight shift, Luffy was inching back.
Leaving?
No.
Don't.
Zoro's body clenched around him.
"Wait," Zoro's voice was a whine.
Luffy's response was to push back in.
Zoro's eyes rolled back, mouth agape. "Mphh," he gasped.
Luffy watched.
The swordsman's body was a tapestry of undiscovered flavor. The blush over his neck and ears now covered his shoulders and upper back. Luffy's right-hand man trembled beneath him, shoulder blades and muscles rippling beneath the skin. All that power shoved into the bedding, twisting like a cat.
That smooth, proud back: not a scar on the unblemished skin. Defenseless, vulnerable, and bowing to his captain.
The narrow, tapered waist. The round, upturned ass. The curling toes and shaking legs. The reddened skin that stretched around the captain's cock.
Luffy devoured the sight. Awed. Gluttonous. He rolled his hips. Shallow. Slow. So he could watch.
"Captain," the green haired man mewled. His face was red and contorted with pleasure, a cross between the way he'd look when drinking and when waking up.
Luffy's hand found the man's smaller cock; Zoro whined. His body was alive with sensation, his legs spreading wider, his ass pushing back against the thickness inside him.
"Uuhhhnn… Luffy," he panted, his body moving of its own accord, bones humming.
The rubbery pirate rocked harder, slow, deliberate, his grip on Zoro's cock twisting. The swordsman's body responded in kind, his back arching for his captain.
The cabin was filled with the sound of wetness and breathing, wanton sighs and dizzy moans danced from the swordsman's tongue, body behaving on instinct.
Zoro's hand reached up to grip the wood of his bed, his knuckles white. Sobbing. Lost.
Luffy leaned in closer, his groans right in Zoro's ear, his tongue licking against the shell. Biting.
"Ahn!" Zoro's voice was high, a squeak.
The swordsman's thighs were trembling, his eyes unfocused as he stared at his pillow, his body crazed by his captain's cock.
"Capta-aain," Zoro bawled. His hips bucked back, meeting Luffy's thrusts with a wet slap. The pain, the bluntness, the fullness, the burn – he was climbing again, his stomach tightening into a fist. "Harder," he sobbed.
The rubbery palm left Zoro's cock, both hands gripping the larger man's hips with violent fingers. Luffy pulled back. And shoved back in, thrusting firmer, deeper, faster – pounding him into the bed. The sound of it pained the air.
His swordsman cried and babbled beneath him, howling at the hardest thrusts. Zoro's body was so tight around him, squeezing and spasming with each movement. It was like nothing Luffy'd ever felt before. He couldn't get enough. Each push, each sound, each movement felt like he was discovering something new and untold.
Zoro's head lolled, drool covering his pillow as his body bounced up the bed, ragdoll.
Luffy's rubbery dick pumped into him, stretching him wide as it billowed at the tight rim, the sight of it surreal and obscene.
The captain's thrusts grew frantic. He felt something building inside of him, a pressure that threatened to burst. His grip tightened on Zoro's hips, his strokes becoming more erratic as he chased the feeling.
A keening wail tore from Zoro's throat, raw and unbridled. Zoro's body clenched around him, his hole spasming wildly, and Luffy watched in awe as his swordsman shot watery ribbons of white from his dangling cock. The larger man's body shuddered and contorted, the muscles pulsing.
It was unlike anything Luffy had ever seen. Mesmerizing. Zoro's body squeezed and sucked at his cock. The feeling had Luffy's eyes rolling into his head. Something was coming. He slammed into Zoro one last time, and his vision went white. Unlike anything he'd felt before.
The heat of his climax filled his swordsman, the huge rubber cock pulsing deep inside.
Zoro's body went slack, his breath coming in shuddering gasps.
Luffy leaned over him, panting. He was still hard, still buried to the hilt inside of Zoro's ass. He could feel his heart racing, the blood pounding in his ears.
“Oi, Marimo! When are you gonna—” Sanji froze at the door, words caught in his throat as he gaped. Zoro didn’t seem to notice the audience – trembling out choked breaths beneath his captain.
A beat.
The door closed.
For a moment, they lay there, the only sound their ragged breathing. The room was filled with the scent of sweat. Luffy felt like he was floating.
His erection was starting to die down.
Zoro's hole was red and stretched around the thickness of him, still tight enough to squeeze a deep band of pressure into his rubber cock. With a groan, Luffy pulled out, his dick slipping free with a vulgar pop.
Thick, white spend spilled over Zoro's ass and thighs. So much of it. The sight was too much. He felt dizzy. He collapsed on top of the larger man, chest heaving.
Minutes passed, Zoro warm beneath him.
"Zoro?" He breathed.
Nothing.
He turned his swordsman over.
A silver, glazed eye looked up at him, slow and sticky.
Luffy felt his dick start to throb. He swallowed.
"Zoro. One more time."
The mouth moved.
"... Yes, Captain."
