Luffy was the worst to have sex with.
Not because he was bad at it.
Quite the contrary, actually.
The Strawhat captain was just incredibly impulsive, a trait Law wasn't at all familiar with.
There'd been one too many times Law had been pulled away by the other - no matter the time of day nor place - just to be dragged into an empty room or narrow alleyway. Luffy would trap him against a wall, shove him onto a bed, and ravage him like some starved animal.
Law couldn't reject him, the lips on his neck and hands on his ass working to turn him into putty each time, their push and pull act only serving to make the surgeon wetter. Luffy would overpower him with hands on his wrists, shove a knee between his thighs, and effectively silence him with a long growl.
"Traffy," he'd say, his nose pushed into Law's neck, "I want to touch you."
Those words never failed to send chills down Law's spine, his thighs squirming from the heavy throb between his legs, and it was a done deal by that point.
The surgeon had lost count the amount of times he'd been finger banged or straight up fucked in a public place, hiding behind walls and biting on fingers to keep quiet.
It was shameful just recalling it, even more shameful to think of just how much he liked it.
Sometimes they didn't even bother to hide - or Luffy didn't, anyways. Especially not around his crew.
The most notable was in a run down tavern, filled with pirates and criminals alike; the low lit bar a bustling mess of fights, cheers and drunkards. Law had been sitting between Luffy and Zoro, the couch they were on situated up the stairs and at the back of the room, and for whatever reason Luffy decided that was the perfect place to tease him.
It started with a hand on his thigh, then a bright, devious smile from the strawhat captain, and suddenly lips were on his neck. Zoro was completely unfazed by it, not even blinking when Law was gasping for the man to stop, and only glanced their way when the surgeon was pulled into Luffy's lap.
Law's back was pressed against Luffy's chest, an arm wrapped around his waist to keep him still, and his face went a bright pink when a hand slipped between his clothed thighs.
"S-Strawhat-ya!" he'd cried, fingers pushing into his cunt through his jeans.
A strong rub had Law's eyes blowing wide, the surgeon trying to grab Luffy's wrist to stop him with little success. That action seemed to make Zoro chuckle, the swordsman putting his drink down and watching them with a keen eye.
"Oi, oi, Luffy. Shouldn't you be nicer to him?"
Law couldn't believe how mundane he'd made it sound, as if Luffy weren't stroking his pussy in the middle of a fucking bar.
"Don't worry, Traffy likes it," Luffy laughed, moving to unbutton the blue jeans, "and no one here cares. Right, Traffy?"
Law wanted to speak up, to say that he very much did care, but he was rendered speechless when fingers snuck under his pants to push over his sensitive clit.
"Ah?! Hah!"
The swordsman laughed again, watching Law involuntarily jerk up into the captain's touch. The strangers walking around was bad enough, he could feel the depraved stares from other pirates digging into him, but it was made even worse with the Strawhats' cook walking up to them.
"Is this what you're all doing up here?"
Law heard Sanji before he saw him, face going redder still when a finger slipped over his soaking hole. The surgeon bit his lip and fell back to dig his face into Luffy's neck, feeling the Strawhat captain laugh from the vibrations rumbling through his chest.
"Oh! Sanji!" Luffy cheered, completely normal with his usual smile.
As if he wasn't sticking a goddamn finger inside Law at that very moment.
"Strawhat…!" Law growled out, turning into a pitchy moan at that finger sliding knuckle deep.
The two beside them started bickering in their usual way, completely casual about this bizarre situation, and they only paused when Luffy made a sound of intrigue.
"Ohh, Traffy, you're really tight today!"
Law could've died of embarrassment, digging his nails into Luffy's arm as an attempted warning. But his body failed him, those fingers curling inside of him making his hips jerk up as he let out a long whine.
There was an annoying exhilaration to it, a sense of sick excitement Law didn't think he'd like until meeting the strawhat captain, and it didn't help when he heard the swordsman pipe up next to them.
"You getting bothered, curly?"
Law peeked up to see the cook had been pulled in by Zoro, the scowl on his face mixed with a light blush. It was indication enough, made more obvious by the hand squeezing Sanji's ass.
What the hell was wrong with this crew?
There was no time to think about it when Luffy started sliding his fingers out of him, hammering back in to hit sensitive areas. Law clung onto the captain tight after that, shamelessly rolling his hips to meet with Luffy's fingers for that delicious friction.
The swordsman and cook had vanished by the time Luffy started to pull his jeans down, pushing them far enough to expose his dripping cunt to the entire bar. He would've screamed had he not seen a similar picture in different corners of the room, the tavern filled with, presumably, prostitutes - a detail he hadn't noticed until now.
Law couldn't tell if that made things better or worse, but his mind quickly turned to mush when Luffy's dick started to slip in, Law's eyes rolling into the back of his head as that thick cock bottomed out.
"Isn't this exciting?" Luffy breathed into his ear, giving the man no time to adjust when he immediately thrusted up.
It was insanely exciting, the tingles of pleasure like lightning bolts up his spine.
And so, Luffy had openly fucked him in a bar.
Yet, despite it all, that still wasn't the worst part.
The impulsiveness was somewhat manageable, the voyeurism was a guilty pleasure, but the most embarrassing part was Luffy's stupid mouth.
He just couldn't stop fucking talking.
Law especially realised it now, with Luffy having pulled him into the aquarium bar to once again have his way with him.
The younger had guided him to the couch, stood over him to kiss up his neck, and Law's breath hitched when he felt Luffy dig his nose into his skin and inhale deeply.
"You smell so good, Traffy," he sighed, lifting a knee to straddle the surgeon while his other leg stayed planted on the ground. "And your skin's so soft, it's nice to kiss."
"S-shut up," Law had tried to demand, cut off by a yelp when the other pushed him onto his back.
Luffy crawled on top of him to cage him, Law's heart skipping a beat at the familiar hunger in the younger's eyes that only he got to see. There was a dark leer to it, a dangerous shine you'd see in that of a starved beast, and Law flinched at the hand touching his face.
"And you have golden eyes," Luffy continued to speak, leaning down to get a closer look. "You're like a treasure, Traffy. So pretty."
Law blushed a scarlet red, his body turning hot from such embarrassing words alone.
He turned away and mumbled "Don't call me that," being forced to meet Luffy's eyes again when that hand jerked him back.
"Don't move away," the strawhat captain's voice was low now, emitting a dominant aura Law was positive he didn't do on purpose. "I wanna keep looking at you."
A deeper blush adorned Law's features, the surgeon squirming slightly at feeling his arousal spring to life. Luffy noticed it too - as he always did - his hand now sliding down the man's sensitive neck.
The caress had a small gasp escaping Law, Luffy's other hand moving up to comb through his dark hair before pulling it, craning his neck back. The thrilling combination of sweet and rough had Law silently whining, his hips involuntarily jerking up and allowing Luffy to slip a free arm around his waist to keep their bodies pressed together.
Luffy leaned in closer, breathing hotly on Law's neck and licking up it with one long stripe just to taste him. Then lips pressed against a red ear, the younger's whispering sending shivers up Law's spine.
"I'm gonna mark you," Luffy panted, rolling his hips to grind his semi-hard on against the surgeon's throbbing cunt.
Law gasped and grabbed Luffy's arms, biting his lip when he rolled his hips again.
"D-don't," Law tried, wrapping a leg around Luffy to pull him closer, "people will- ah!"
Luffy wasn't listening - as per usual - and decided to bite down into tanned skin hard enough to hurt. He still needed to learn his own strength, particularly with that stupid mouth, but the pleasurable sting had Law mewling.
The hand in his hair let go to move down his body, joining Luffy's other arm to wrap around Law and effectively lift him off the couch. With another bite to his neck, the younger started dry humping him with long rolls of his hips, Law rolling back to create a sweet friction and feel Luffy's cock push against him through his pants.
It was hard to control himself around the strawhat captain, the man's impulsiveness contagious with how he manhandled him, and Law moaned softly with each grind of their bodies.
"Mm, Traffy," Luffy groaned, eyes staring up to drink in all of Law's reactions. "You make really nice noises, I love hearing you."
Law lightly punched the other's back, weakly stuttering "I-I told you to shut up" while still grinding back. It had Luffy smiling, one of the hands holding him up now moving under Law's shirt.
"You're funny, Traffy," Luffy snickered, bunching his shirt higher and higher until sitting up to slide it off.
Law helped him along, raising his arms to get the annoying piece of clothing off, and Luffy wasted no time in unbuttoning his jeans to go with them.
"You're shaking a lot," Luffy pointed out, hooking his fingers under blue spotted pants to start sliding them down. "Is it because you're excited?"
"Can't you just be quiet?" Law did his best to scowl, not really effective with the blush that was painting his face crimson.
Luffy grinned, laughing in his usual mischievous way. Those dark eyes immediately glanced down when Law's underwear came into view, seeing the material dirtied by a wet spot soaking through.
"Oh," Luffy just about sighed, ripping the rest of Law's jeans off while eyeing the man's crotch - the heated gaze making him wetter.
A curious finger pushed into his clothed pussy, the surgeon panting and lifting his hips into the touch. A second finger joined the first, rubbing over the wet patch and pressing to make Law throw an arm over his face.
"Hah…ah…!"
The touches were light, but they still made him throb - choking on a gasp at a thumb rolling over his clit. Luffy experimentally pinched, Law's eyes popping wide as he violently jerked from the sudden action.
"Luffy!" Law exclaimed breathlessly, glaring at the laughing captain from under his arm.
"You said my name!" Luffy smiled, watching the surgeon go a dark red with the slip of his tongue, "I like it when you say it."
Law could only tell him to shut up so many times, ready to do so again until fingers hooked under his underwear and started sliding down.
"I wanna hear you say it more, Traffy."
The surgeon held his breath as his privates were slowly exposed, small strings of slick showing just how much he'd been anticipating this. No one else could rile him up the way Luffy could, Law completely drenched from teasing alone.
"S…Strawha- ah!" Law broke off in a moan, the younger biting his thigh with sharp canines.
After a quick apologetic lick, Luffy grumbled "Use my name," sliding the surgeon's underwear off in the process.
Law wanted to reject the younger, the request admittedly an intimate one for him, but he froze when Luffy pushed his legs apart to crawl between them.
There was a careful affection to the action - a familiarity that made Law's heart thump - and when he looked back up, catching Luffy's eyes on his own, he just about squeaked at the low voice that slipped from the younger's lips.
"Law."
Tanned thighs snapped together, Law unable to control it as he trapped Luffy's head between them, involuntarily pushing his hips up to try and reach a smiling mouth.
"D-don't-! Don't!" he cried out, a broken whine escaping him from the tongue that licked up his dripping cunt.
"Mmh," Luffy made a satisfied sound, digging his tongue in and sucking hard to loudly pop off of his clit. "You always taste so good, Law."
Said man whimpered at his name being used again, legs squeezing tighter around Luffy to silently beg for more.
Luffy happily obliged, slurping loudly and messily at Law's twitching pussy - the drool running down his chin mixing with the surgeon's overflowing juices.
With a groan, Luffy grabbed long legs to push them up, keeping those thighs wrapped around his neck as he forced himself forwards to dig even deeper. It had Law throwing his head back, attempting to anchor himself with fingers clambering to grab at dark hair.
"Hah! I-I can't- nnh! Aah!"
Law sobbed desperately, the filthy head he was getting making his body tremble and jolt. Each lick against his clit had his eyes rolling into the back of his head, while each strong suck was toe curling.
Luffy held his tongue out to press it flat against Law's cunt, shaking his head rapidly to create a wonderful friction that he knew had the surgeon wailing.
"Fuck!" Law's back arched, tugging Luffy's hair harder with a gasp. "L-Lu- hnn!"
The younger immediately stopped - Law almost screaming because of it - hearing an excited snicker from the other.
"You nearly said it again," Luffy licked his lips, savouring every last drop Law gave him.
The surgeon quickly shook his head, folding his arms over his face to hide himself. "I didn't! I didn't say anything!"
Luffy forcefully pushed his legs apart, untangling them from his neck and pinning them to the couch. The new position was humiliating, Law blushing to his chest at his clenching pussy being on full display.
"That's okay," Luffy chimed, dragging his fingers between Law's quivering lips.
They slowly rubbed up and down, teasing around his hole to force a string of whimpers from the surgeon. He gasped when Luffy used his free hand to pull one of Law's arms up, unwillingly revealing his flushing face.
Those usually shining eyes dug into him - dark and domineering. They pressed Law down to force a shiver, an effect only Luffy had on him, and his breath caught in his throat when the younger spoke through a large smile.
"I can just make you say it."
A single finger pushed in, the slow drag making Law let out a long, drawn out moan. Luffy watched him the whole time, always curious about his reactions, and tilted his head as he abruptly slammed up to the knuckle.
The sudden jab at his sensitive walls had Law spasming, crying out when Luffy immediately did it again. His jolting hips only pushed the finger deeper, unable to regain control of himself with the intense stimulation.
"It's only one finger," Luffy hummed curiously, wiggling it around to watch Law squirm, "you're really sensitive."
Law whimpered and tried to close his legs, Luffy immediately lifting a knee to keep them spread wide open. He was using his other hand to stubbornly pull at the surgeon's wrist, making sure to keep Law's arm from his face so he could stare at it.
"D…don't…" Law managed to squeak out, turning his head to the side in embarrassment. Whatever else he tried to say didn't come out, or couldn't come out, not with a second finger sliding its way in. "Ah… s-stop… oh-!"
Luffy chuckled softly, twisting his wrist and ramming it forward to see Law's eyelids flutter.
"You're really squeezing me," the younger said, jerking his fingers to have a pool of wet drip out of Law's cunt. "And you're so slippery right now."
Law heard how wet those words made him when fingers bent inside of him, a deafening squelching sound burning his ears. His tattooed hand quickly whipped down to Luffy's wrist, digging nails into rubber skin in a silent plea; the younger taking the opportunity to swoop down and take Law's lips in a messy kiss with his face now exposed.
A tongue immediately pushed into his mouth, that distinct taste of meat Luffy always had clouding his senses. The man swallowed his moans when he slipped a third finger alongside the other two, immediately dragging them out to slide them back in.
The stretch was intoxicating, goosebumps crawling up tanned skin as his walls were rubbed. He used his grip on Luffy's wrist as a leverage to roll his hips up, whining when his tongue was heartily sucked by a hungry mouth.
"You taste good here, too," Luffy muttered against his lips, making Law yelp when he dove down to bite his neck again, letting go to lick over the fresh mark on his skin. "You taste good everywhere."
Luffy suddenly sat up, the surgeon panicking when he moved to pull his fingers out. He dug his nails harder into rubber skin, intrigued brown eyes meeting his own at the reluctance to let go.
Realising what he'd done, Law quickly looked away and let go with a blush, hearing Luffy laugh at such a reaction.
"Did you think I was leaving?" Luffy grinned, shrugging his shirt off to carelessly throw it across the room.
Law shook his head shyly, "No, I…"
He didn't even know what he wanted to say, his head completely muddled from the tingling of his skin, breath hitching when a hand dragged up his pussy.
"Don't worry, I won't go," Luffy reassured, rubbing around Law's clit to make him shudder. "But I don't want to wait anymore, you know."
His hole clenched around the air, desperate to be filled again, "W-wait?"
Luffy beamed, "For you to say my name!"
Law cried out upon three fingers slamming into him, getting no time to breathe when they pulled out to slam in again. The rapid assault perfectly hit tender areas, Law lifting his arms to hide his face once more when he started moaning uncontrollably.
He could feel Luffy's eyes digging into him, the younger picking up the pace to make vulgar slapping noises echo throughout the room. Law knew exactly what he was trying to do, Luffy being weirdly fascinated by his bodily reactions, and tried to twist his body away when that familiar building sensation began.
Unfortunately for him, Luffy saw right through it, and grabbed Law's upper thigh with an iron grip to keep him still.
"Why are you moving away?" Luffy frowned, an innocence in his voice Law was positive was fake.
"Y-you- nnh!"
Law couldn't even curse him out, back arching at his sweet spot being pummeled into by the relentless fingers.
Luffy felt it, using the way Law clamped down on him as an indication, and angled his thrusts to drive back into that same spot.
"Stop! Stop!" he begged, completely at the younger's mercy as he writhed around beneath him. "St- hah! Luffy!"
It slipped out, and at any other time Law would scowl at the man smiling wide towards him. But currently, there was too much for his body and mind to focus on, and he sobbed at another rough plunge.
"Please!" he gasped out, trying desperately to stop what was coming. "Stop, Luffy! Please!"
"Now you're really loud!" Luffy grinned, not listening to a thing Law was babbling, "Keep saying it!"
Tears welled in golden eyes, Law's hips rocking automatically to meet thick fingers. He could feel his insides being completely jumbled, the couch soiled with how much Law was dripping, and he sharply inhaled when Luffy sped up even more.
"Ah! Luffy!" Law wailed, drawing out the younger's name with a pitchy whine, "Luffy!"
It was becoming too much, the hammering against his walls like constant jolts of electricity, the throbbing of his cunt quickly becoming overwhelming.
Law screamed out with one more brutal thrust, scrambling to try and tear Luffy's hand away, but it was too late.
His body spasmed when he shifted, those fingers going deeper because of it , making his thighs tremble when a clear liquid shot from his pussy in strong spurts.
Tears fell from Law's eyes, seeing as it hit Luffy's bare stomach, and he sobbed and squirted again when digits curled up inside him.
"You're letting out a lot tonight," Luffy spoke with a lick of his lips, taking his fingers out to watch the surgeon's gushing cunt.
Without warning he shoved them back in to make Law's back arch, dragging out again for another spurt to shower his stomach.
"Luffy!" Law begged with a broken moan, his face glowing red from both exertion and embarrassment.
The younger continued to slam his hand in, Law yelling each time, unable to control the way he squirted whenever Luffy pulled out.
"You're really amazing, Law," the strawhat captain panted, the filthy action both fascinating and tantalising for him.
Luffy used his free hand to simultaneously unbutton his own pants while still finger fucking with the other - his clothing now drenched - and groaned when he finally pulled his hard cock out. Law hadn't noticed, completely devastated with his eyes rolled into the back of his head and mouth hung open, choking with each startling spray of his pussy.
"Luffy…Luffy-!" he gasped breathlessly, twitching when those merciless digits finally completely drew out.
The emptiness was short lived, sudden hands on Law's thighs shoving his legs back and further apart. Luffy hurriedly positioned himself, finding Law's hole on near pure instinct, and had the man shrieking when immediately shoving his tip inside.
"AHH!"
Gold eyes blew wide, Law's arms flying up to try and cover his face again when Luffy quickly slid in.
Luffy audibly growled at that, grabbing those arms and pinning them back against the couch. He leaned down to push their noses together, making a tattooed body bend as his cock pushed in deeper, drool falling from Law's mouth at the filling stretch.
"Look at me" Luffy demanded, his heavy tone sending a shiver up Law's spine.
His eyes nearly rolled into his skull when the younger bottomed out, becoming dizzy from the amazing girth stuffing him full. Luffy gave him no time to adjust, squeezing tanned wrists as he pulled out, and stared intensely at Law's face as he rammed in.
"Hn-! Ah!" Law shook fiercely, toes curling from Luffy's dick hitting all the right places.
"Law," Luffy breathed, dragging out again to swing back in, "feels so good."
The sting of skin against skin made Law squeeze around Luffy tighter, the slapping sound mixing with the wet squish of his pussy creating a lewd noise.
When Luffy sped up Law could only lie there and take it, his legs wrapping around the younger while nails dug into his wrists. His vision was blurred by tears, his mind turning foggy with the heated grunting above him, and he moved best he could to meet Luffy's thrusts.
"L-Luffy I'm- I-" Law tried to speak, gasping at the waves of pleasure racking through his body.
He jerked when that thick cock pulled out to only the tip, another gush of liquid spraying from his cunt when it dragged against just the right places, the dirty action making Luffy hum.
"You're so pretty," he sighed, driving in to have Law crying. "Law's so pretty."
The younger started repeating those words, Law whining all the while, squirting and making a mess every time Luffy drew out to pound back in.
"Luffy!" Law whimpered brokenly, a coiling sensation in his gut tightening, "Luffy!"
He felt the cock inside him grow bigger, brown eyes above him lidded with a possessive shine, and turned incoherent when Luffy angled himself to abuse his sweet spot.
"Hah, you're so amazing," Luffy groaned, the hot hole clenching him harder with his words. "I really like you, Law."
Law couldn't take much more, tears streaming down his face while his juices dripped down his thighs.
"Lu-ffy!" he choked out, his entire body jostling with how hard he was being pounded. "Luffy! Luffy!"
It was all he could say anymore, it was all he could think. He'd been fucked stupid by the man, a mess of sweat, slick and sticky skin - every thought stolen from him to be replaced by Luffy.
No one else could fuck him like this, could hold him like this, could woo him like this.
No one else could turn him unintelligible with the pure affection Luffy gave him.
No one else could drive him crazy.
"Luffy!"
It only took a few more thrusts, Luffy whispering sweet nothings into his ear while he railed him. With one more hefty plunge, Law's back arched as his eyes rolled back, and he came with a scream.
The sweet squeezing caused Luffy to come with him, grunting as he released inside Law to paint his inner walls white, Law gasping at the hot sensation.
They stayed stuck together as Luffy pumped him full, the two of them shivering in each other's arms. The younger eventually released Law's wrists in favour of stabling himself with a hand against the couch, Luffy huffing a deep, satisfied sigh when finally being milked dry.
"Haa, that felt good," the strawhat captain smiled, speaking the same way he would after a hearty meal.
Law flushed pink at the thought.
"Get out of me," he grumbled, wincing when the heavy cock slid out of him.
"Sorry, sorry," Luffy laughed, not a hint of regret in his voice. He stopped to look down at himself, wiping his hand on his stomach with a curious expression before saying "I'm all wet."
Law's foot shot out to kick him in the chest, knowing it wouldn't hurt the rubber man, and hid his face with shaking hands.
"D-don't say that!"
Luffy grabbed Law's ankle, moving it to lean back over the surgeon and stare down at him.
"Are you embarrassed, Traffy?"
"I'm not!" Law immediately lied, blushing at the feeling of cum dripping out of him. "And why did you come inside of me?!"
The man hummed in that loud way he usually did, grinning to finally answer "Because it looked like Traffy really wanted it!"
Law nearly choked, whipping his hands from his eyes to scowl at the younger.
"Where'd you get that idea from?!"
Luffy raised an eyebrow, tilting his head at the agitated other. "Well you kept saying 'Luffy, Luffy', so…"
Law's eyes widened as he burned a bright red.
He went even redder when he realised Luffy was completely correct.
He could've died on the spot.
"But you know," Luffy continued, moving down to get closer to the other captain, "I really liked it."
They both paused, looking into each other's eyes through the silence.
There was a warmth in that familiar brown, one that blanketed Law unlike anything else.
It was a warmth that caused his heart to skip, the faint buzz running up his skin making his stomach do flips.
"S…so?" he dared to ask, that sincere smile just about blinding him.
"You should use my name more!"
Law grabbed Luffy by the face, squeezing his squishy cheeks together in mock punishment.
"Not on your life, Strawhat-ya."
The younger made a noise of complaint, pouting best he could.
Luffy was impulsive, he was greedy, and he was completely stubborn.
But through it all - with his smiles, his actions, his words - Law couldn't help the fondness he felt for such a man.
Luffy was irritating to no end, and somehow, Law loved it more than anything.
