Work Text:
It's a nice, sunny day out on the moby dick deck.
Which, of course, could only spell disaster.
Luffy'd only been on the large ship for a short while, and most of the time he'd been in the medbay.
Turns out crashing a war and almost dying from poisoning could give you serious injuries, go figure.
(At least Bread hair was cool! But the man's constant talk about his cooking made the confinement to the infirmary that much worse. It also made him miss Sanji that much more.)
But now he was finally out and about, ready to investigate the huge vessel and meet Ace's family and all of Jack's aunts, uncles and other family.
Bouncing around, he met the eyes of many people out on deck working, and many stopped him to clap him on the shoulder for whatever reason, but no one really seemed to have time for conversation.
Usually he would just follow them, but there was so much to see on the ship, he didn't have the time - Especially if he wanted to make it to dinner. Whenever that was.
Right, he should probably ask someone about that.
He decided to head to the figurehead as his starting point before truly exploring - he didn't know how much time he'd be spending on the ship (especially seeing as Jack was on his way,) so therefore he figured he'd better familiarise himself with the mount.
Finding the large whale-figurehead, Luffy almost stretched towards it before remembering his stern warnings of 'No stretching' his still healing injuries. He didn't need to be wrapped in bandages anymore, but that could quickly change.
The breeze hits his face, salty sea air engulfing his nostrils as he breathes deeply.
He loves the ocean, it makes him feel free, with no end in sight, fit for adventure.
He'd just sat down crossed legged, when he hears footsteps from behind, coming towards him.
Turning to look at the approaching person, he sees it's the green guy that was present at the commanders meeting when they'd first arrived.
He thinks his name was Spring sock or something.
"The nurses finally let you leave the infirmary aye?"
"Yep!"
"So… " The man carefully walks over to where Luffy's sitting, it's a big figurehead so there's plenty of room.
"You and Ace… you said you'd been together for around 7 years?"
"Little more than that yeah!," He paused for a moment, face twisting in thought, "Why?"
Spring-Sock's grin widened to a devilish degree, it reminded Luffy of Sanji's face when he had the opportunity to show up Zoro.
Quickly ridding his head of those thoughts so as not to think about his crew too much or how he failed them and that they don't know where he is or if he's- No, we're not going there. Stop it.
"And I was wondering… Have Ace… y'know. Been the catcher?"
"Well yeah he's caught me plenty of times"
"No I mean.. Are you the pitcher or the catcher?"
"I'm a rubberman"
"...Right"
Luffy feels kind of like he's either missing the point, or Spring-sock forgot what his devil fruit powers were in the span of… however long it is he's been on their ship.
'Oh well, guess I'll ask Ace later tonight'
Ace was in his (and, currently, Luffy's, too) room, waiting for his brother to join him for the night.
Luffy's never been one to sleep alone, but since Marineford the boy's been… Well, more octopus-ey than the usual.
Well, not that Ace can blame him. He did almost saw him die.
And… It's not like he's any better.
Whenever Ace sees his brother's now scarred body, he always feels a stab of guilt.
He was the one to cause that.
The now slight constant strips of discolored skin from heavy poison etching into rubber skin and rotting it on the spot, small specks of burns in an imitation of Ace's own skin as if laughing at him, and countless scabbed over cuts, deep enough to scar his brother's otherwise nearly unblemished skin.
Luffy himself doesn't seem to care, but for Ace it serves as a reminder of one of the many ways he failed his brother.
Speaking of the man.
Ace looks up from the wall he'd probably been staring at intently as his brother enters their (currently) shared room. Luffy looks happy and well satiated from the after dinner-dinner he partook in. Ace can't not smile fondly at the sight.
His brother comes right up to where he's sitting against the headrest, and climbs into his lap.
This close he can study the dimpled smile in detail, and small sun-made freckles barely there on the tip of his nose, tracing the self-induced scar beneath his left eye as his fingers go through dark locks that match his own.
The quiet moment is ruined when Luffy starts to speak.
"Hey, Ace?"
"Mhm?"
"What does it mean to be the Pitcher or the Catcher?"
Hold up-
What?
Did he just.
No, surely not.
"Uh. Could you repeat that?"
Deep onyx eyes blink at him, tilting his head, Luffy repeats what he'd said.
"Being Pitcher or Catcher. What's it mean?"
…
Guess he did hear correctly.
"...Who told you about that?"
"Spring sock"
Spring sock? Spring so… Spring song….
Ah..
Haruta. Of course.
I'll get him later.
"Right… Um. So, the pitcher is the one that gives and the catcher is the one that.. Receives"
"Receives what?"
"Well, if you were to have sex and you're the one.. Giving it, as in, on top, doing the penetration, if you will, then you'd be the pitcher."
"Ahhh. So Ace wants to be the Catcher! Ace wants me to penetrate him?"
Wait.
Wait wait wait.
WAIT-
"And that'd mean Ace would be the one on bottom. I can do that! If Ace wants that, then I'd be happy to! It feels really good, too! I get why you'd want that!-"
Luffy keeps on talking, completely oblivious to Ace's inner freak out, considering he's currently taking his shirt off-
FUCK. he's Not listening -
"Ho-Hold up a second there Loof-"
"Ah, we need something slippery. You once said that's an essential. I gotta prepare you, too!"
Yeah. Definitely not listening.
Sitting on his lap, Luffy smiles that 'seductive' smile of his (at least he's not wearing the oven mitts and sunglasses this time), looking up at him with half lidded eyes.
"You have the slippery stuff in your drawer, ye?"
Ace nods on autopilot. Luffy grins.
Luffy's hot fingertips travel up Ace's bare torso, leaving ribbons of goosebumps in his wake. His brother leans in, kissing him softly, licking the inner corners of his lips with his, for once, regular lengthened tongue.
The kiss is heated, and Luffy's hand sneaks its way into Ace's boxer shorts, his other hand slowly spreading Ace's legs.
His brother quickly drags down his boxers fully, a rubbery hand engulfing his slowly hardening dick, before spitting in his palm and resuming, slick hand moving in a steady rhythm on his erection, as Luffy breaks the kiss, letting his mouth travel downwards and gliding over his neck instead.
A slick tongue encircles his nipple, gently sucking, before moving further down.
Ace has a bit of a hard time keeping track of Luffy's acts though, as his brother's grip speeds up and tightens.
He hears the squelch of the lube, and feels Luffy carefully starts to circle his rim.
Ace's so turned on right now, he's forgotten any reservations he'd previously had about this.
He feels like he's forgetting something, but if he forgot then surely it wasn't that important anyway.
He starts easy with a single finger. It doesn't feel weird, it's just something to get used to.
Huh, maybe this won't be so bad after all? Luffy did always seem to enjoy it…
Barely a minute later, and he adds another finger. This time Ace feels the stretch, but still, not too bad. Just a little unusual.
After a few minutes, a third finger is added, and this one he feels.
It's a more extreme feeling than the two fingers, and this one makes itself known a lot more than the first ones.
But again, he just needs to get used to it, it's not that bad.
Luffy's hand picks up speed on his erection again (his brother had stopped briefly as he'd been concentrating his efforts elsewhere,) and Ace promptly forgets about any discomfort he'd had.
It returns full force a few minutes later when Luffy's fingers retreat to make way for something bigger .
A lube-coated head slowly pushes in, and Ace has to bite his lip because… It.
It burns.
And he'd know, he's literally made out of fire.
Luffy bottoms out, balls resting against Ace's skin, he'd forgotten that his brother wasn't small by any means - but he's definitely remembering now.
He meets his eyes, lidded, mouth open slightly to breathe better, his lips quick upwards before he begins to pull out about halfway, slamming back in.
It causes small sparks of pain at the base of his spine, paired with the burn of his insides.
But.. It's… His dick, it's throbbing painfully. His face feels flushed, and his legs spread themselves further, a calf encircling Luffy's back as if to push him further in.
Because the burn, the pain.
It makes him feel hot-
He bites his lip so as to not cry out in pain mixed with a pleasure cocktail that's brewing inside his veins, and Luffy must see it as he smirks and leans down to kiss him, letting their tongues meet and mingle as he speeds up.
His brother bits down hard on his lip, and that paired with the burn from the stretch makes the fire in his bloodstream boil over, and suddenly he's cumming.
He's cumming so hard, he sees stars beneath his eyelids, and it feels like his vision is blacking out.
Wait..
It's.. It is blacking...out…
"Ce-?"
"CE!?"
*Thud*
When Ace wakes up, he realises he's in the medbay. For some reason.
He tries to sit up, but his lower back and his ass (oh gods his ass-) screams at him.
Guess we're laying down, then.
It's dark in the room, and quiet save for the sound of Thatch's snores.
So he lets himself go back to sleep.
It isn't until the next morning he learns the horrible truth.
Apparently, last night, and a few hours before he woke up, Luffy had run out on deck, butt naked, looking for a nurse because he thought he'd killed Ace somehow.
Ace had passed out after climaxing.
Or, well, he'd had a narcolepsy attack. While Luffy. Was still. fucking him.
And instead of getting the nurse he found, oh no, Luffy ran back to his room to get Ace, slung him over his shouler, also butt naked with cum all over him, and ran back out onto the still busy deck, and then went over to the nurse.
Ace has never wanted to die more in his life than he does right now.
Luffy had dressed him it seems, and the nurses brought him to the medbay to make sure it wasn't his injuries from the war acting up.
Or… Maybe, it could be that Ace only just now woke up from his battle induced coma. He totally went into that, yeah. That makes sense.
Shame forgotten, he acts based on that premise the rest of the day, talking to the nurses and discussing his status. They decided they'd keep him in the medbay a little longer as they didn't deem him ready to leave yet. Ace had no problem with that, he did just wake from a coma after all.
The next day he realised that he'd not been allowed any visitors, and, that Thatch had been strangely quiet. He wondered if the man was asleep, which'd make sense giving the state of his injuries.
That was when he realised he only learned about Thatch's condition after the war.
So that means he, in fact, had not been in a coma and he had in fact bottomed for Luffy only to have an attack in the middle of it all.
Because of fucking course that's what happens the first time he had to do that.
He's not surprised, what'd he expect? That everything goes smoothly for once? Yeah, right.
The pain wasn't even that great, like what the fuck is wrong with him? Why would he like that? He's not messed up like that. No way.
He spent the rest of the day feeling angry at himself, anger, that was fueled by shame.
On the third day, the nurses hadn't stopped by more than once, excluding meal times, and Ace was starting to wonder why they hadn't deemed him fit to be released yet.
Maybe… It wasn't so bad. It could've been worse. Bottoming like that. Again.
But not, like all the time. And he's still not into the pain thing.
On the fourth day, the nurses didn't come.
Or maybe they did and he just didn't notice.
That wouldn't be the weirdest thing he's ever done apparently…
Maybe they just don't want to be near him, knowing he came from pain. Like, who would even want to touch him after finding that out? Luffy would definitely think it'd be weird.
He can even hear Sabo laughing at him from above.
If the nurses see him cry, they don't say anything.
On the fifth day, they finally tell him he can go.
It's as he's walking from the infirmary that he realises how stupid he is.
Of course Luffy wouldn't care if I like a little pain during Sex. What was I thinking?
No one even looked at him weirdly or questioning the entire day, further proving it was all in his head.
After a hard day of working some extra to pay back on some of the slack he's been doing lately, he arrived back in his and Luffy's currently shared room.
He hadn't expected to open the door and find Luffy, completely naked on his bed/their bed. Wearing sunglasses. And those damn green 'get ready to take your pants off' oven mitts that keep on popping up.
He thinks he spies a plate of cake and meat in the corner.
Where did I go wrong?
When he doesn't say anything, Luffy puts the sunglasses onto his forehead. And gives him a questioning look.
"Why"
Is all he can say.
He's done this before, but the food is new.
"Meat is sexy, right?"
Well, at least it's not the dick-lasso this time.
"Sure, Loof."
Luffy smirks, before getting up from the bed and waltzing right towards Ace, a stretchy hand sneaking past him to close the door fully behind him. The other hand sneaks out and loops itself in Ace's belt hoop.
"While you were in the medbay, I found some sacred texts that I studied, just for you, Ace"
The hand that's not in Ace's belt hoop strokes his chin teasingly, before gripping his jaw tightly.
Sacred texts…?
Luffy leads his jaw down to his height and kisses him softly, warm pillowy lips opening to make room for a wet tongue that licks its way into his mouth.
Then, he bites down harshly on his lip, and sparks of pleasure dances like ants on his skin up his spine as his pants tighten.
His brother's hand in the belt buckle rips - actually fucking rips - his pants open, dragging them down his legs.
He breaks the kiss, before Luffy lif- holy shit- lifts him and throws him down onto his bed sheets.
Wasting no time, his brother joins him on the bed and settles between his legs, spreading them before bending down to kiss the inner sides of his thighs, giving them a lick, and biting down harsh enough to draw blood to the surface.
It makes Ace's dick throb in excitement.
His brain may be lagging and haven't caught up to the happenings yet but his dick sure have, huh.
As he licks his way to Ace's erection, a stretchy hand reaches for the lube on the nightstand, and clicks it open.
Luffy sucks in Ace's red shiny head and inserts two fingers that are thoroughly coated with what smells like it could be mint scented lube ( why , Loof ?) but Ace can't seem to pay attention to it as Luffy completely swallows him up (oh right, no gag reflex), bobbing his head in tandem to the thrust of his fingers.
In barely no time at all, he inserts another finger, spreading them inside of him, giving him more of that hot burn, which could make him fall apart.
His brother leaves his dick, before pressing Ace's torso down into the bed, taking a pillow, and propping up his hips. He also raises one of his legs and throws it over a shoulder. From where Ace is laying and staring up at Luffy, he feels more excitement claw itself from the base of his spine.
Because from the angle?
Luffy looks absolutely predatorial.
It feels like he's about to completely eat him up, and with that look, makes him hear the crunching of bones, feel hot tendons and muscles snap and break beneath blunt teeth as warm thick and sticky blood drenches the mattress and-
He shudders.
If that's what Luffy wanted, Ace would let him.
Luffy's head probes at his entrance, slowly entering before swiftly bottoming out, punching the air from his lungs.
Dark eyes watch him in mirth, the little fucker planned this.
His brother grins, and slowly draws out till the head's the only thing still inside.
Before slamming back in.
It causes delicious pain to bubble beneath his skin, and Ace cries out in pleasure.
Luffy repeats this, a tight and bruising grip on his hips, watching him with sweat soaked glistening tan skin.
He keeps up the rhythm, and right when Ace thinks he'll come, he stops.
But before he can question him, his brother pulls out and flips him-
Pushing his torso into the bed, letting go of his leg and putting him on his knees, before he takes a hold of his wrists and holds them in a bruisingly tight grip on his back, stretching out his arms behind him.
Luffy re-enters him in a fast move, and promptly restarts the fast pace, slamming in and out of him so brutally harsh and quickly it makes the bolted bed jolt and bounce.
And it's the best fucking feeling he's ever felt - he's drowning in ecstasy, and his orgasm hits him suddenly with no warning -
And yet, his brother doesn't stop or slow down, if anything, he speeds up. Ace screams out in pleasure and overstimulation.
Luffy lets go of his Arms, instead gripping his hair, pulling it backwards causing more ripples of pain to cascade down his sensitive skin.
He feels him lean down against him, he pulls his hair so Ace's throat is completely barred, before kissing, licking and biting down harshly at the base of it, just slightly above his adams apple. Ace probably sounds like a cheap pornstar but like right now he feels like the most pampered whore out there as Luffy sucks and bites marks into his collar bone, biting his ear, while a hand causes red streams of pain to flow down his bare back as blunt nails trace the skin.
Ace has another orgasm, and somehow it just feels like Luffy's getting bigger and deeper inside of him.
His brother leans back again, and pulls him with him so Ace's larger body rests against Luffy's chest, his brother lifts one of his legs again and thrusts at an angle, hitting something inside of Ace that makes his vision go completely white, causing him to come again.
He's pretty sure, that right as he comes, he hears Luffy whisper 'Gumo Gumo no Cock' into his ear.
But he's too busy from cumming all over the bed sheets to really think about that right now.
However, from the feels and sounds of it, it seems like Luffy also finally reached climax, he's so deep inside of him and Ace still feels the hot thick liquid cascade in release.
Luffy slowly lets go of his shaking leg, pulling out and helping Ace lay down as his body's trembling from the overstimulation - and the multiple orgasms.
He opens his arms automatically for his brother for some after-sex-cuddles, and Luffy's quick to accept his invitation.
Ace is on the cusp of sleep, when he remembers he wanted to ask his brother something.
"Luffy… Where'd you learn all this?"
"The sacred texts"
"Which are?"
"Well I asked Bread hair if it were my fault you passed out, when I explained the situation he told me to check his porn collection"
…
Ah.
That would explain the man's silence.
Ace is going to kick him overboard.
"I.. See"
"Was it good?"
…"Yes, very"
He feels his brother's smile on his bare and, probably pretty disgusting, chest.
They fall asleep like that, forgetting to clean up after themselves.
The next morning, and the following couple of days, Ace would walk around with his bite-mark filled collarbone and with a certain air of sated going around him.
The commanders who's rooms were close to the brothers didn't need to look or ask to know.
The second commander walked around with the marks, strutting like a proud bird.
Suddenly, everyone's respect for the young strawhatted captain grew.
(Though, they could have gone without hearing a 20 minute long description on how good Luffy is with his mouth or how much potential his dick had).
Notes: Oh and Harutas nickname: Haru = Spring Uta = Song
Luffy ofc made his own remix
