Sabo had left for a school project little more than a week ago, so Ace and Luffy had had their shared apartment to themselves.

Not that they saw each other often, both men too busy with their respective works. Ace at the shipyard, and Luffy at a dojo with his friend Zoro.

Still, they went to college with their own money paying for it, not wanting to strain their parents.

Their mother, Rogue, had expressed that she and their dads, Roger and Dragon, had been willing to pay for them.

But Sabo and Ace had both refused. Luffy, not really caring either way, just went along with his brothers decision.

Thus, they were usually too busy to actually spend time together.

Not today, though. They'd both gotten a couple days off of work (which is a miracle in of itself, being mid summer after all,).

It was a pretty hot day, too, so neither really wanted to do much, not even play any of the games Makino gave them before they moved in a few years back. They were sprawled on the couch, Ace hanging upside down with closed eyes, Luffy could hear him trying to memorize the grammar rules from an assignment that lay on his brother's bare stomach. Luffy was sitting upright, channel surfing, his own discarded homework lay on the coffee table in front of him.

The heat had completely utterly destroyed any means of focus he'd had in him.

So instead he was going through every single channel on their Tv, which he'd never done, as they always used the same three channels. Spying the number, 122, in the corner, he realised there were a lot of channels. A lot of which he understood nothing about, like a random polish news channel he'd gone by.

He continues to surf, hoping that there's something to catch his attention, even if just a little.

Just as he wonders if he should stop, the channel he lands on makes his eyes go wide.

It's two people, men, he guesses, and they're kissing. He thinks. It looks like it, but it's pretty violent.

They're both in their boxers, Luffy thinks it must be really hot in their rooms for them not to freeze. He'd freeze if it were him.

One of the men reaches down to pat the front of the other man's boxers and Luffy blanches at the sight, he'd only gotten hitten there once, accidentally even, but that hurt .

Ace, hearing his brother's sound of protest, opens his eyes and glances up at him. Luffy looks.. Appalled, for lack of a better term. Sitting up, he looks at the Tv.

"What's up?" He asks his brother, who points to the screen.

"Why would he hit him there? That hurts!" He says. Ace looks back to the screen and takes a better look at the two men on it.

Ah.

A porn channel.

He's not surprised by Luffy's reaction, or, well, lack of reaction, but he Is surprised his brother hasn't guessed it by now.

It's quite obvious two dudes making out with each other.
He snorts.

"He's not hitting him Loof," Luffy makes a sound of protest.

"But the sounds! He sounds like he's in pain. And if he's not hitting him, then what Is he doing?" He asks.

"Nah. Remember the time we had to give Shanks stitches? Grunts of pain sounds different, those ain't it"

Which, again makes sense, giving that it's Porn.

"You're right, it IS different," He says finally. Ace smirks.

He goes to turn off the TV, but Luffy's finger in his belt buckle stops him.
His brother's curious wide eyes are staring at the screen in wonder, as well as… Newfound interest.
Wait.

Luffy's 20 years old, a 20 year old man, and… if Ace didn't know better… He'd think that this was Luffy's introduction to porn.
But, that can't be. He remembers giving his brother the talk years ago.
He swallows.

After a seemingly last loud and wet sounding kiss, the two separate, only for one of them to go down on his knees, kissing the others chest and stomach. Ace and Luffy watch as the man pulls down the others underwear, the man's dick standing up and nearly hitting the other in the face.

Ace, who is 23, has had his fair share of awkward erections moments (as he'd dubbed them) and since Luffy is also a man, he figured his brother must've experienced it before.
Yet somehow, the way Luffy glances down at… his front, and back to the screen.
Surely. Surely he's had an erection before-

The man presses a wet kiss on the tip, before taking it into his mouth.

Ace's eyes widen, and a part of his brain screams ' That can't be hygienic' . Luffy turns to look at him, he looks flabbergasted.

"Why did he bite it off?! ACE? Why would he do that?!" His brother asks, talking so fast Ace takes a little longer than usual to process.
He thinks his brain might've just stopped working because ?
Does Luffy not know what a blowjob is? HAS HE SERIOUSLY NEVER WATCHED PORN?

"Ah yeah, suck my cock you slut" The man not on his knees says.

"Do you… Do you not… luffy… Have you never..." Ace says.
Luffy mumbles something under his breath, and wonders if Slut is the other guy's name.

He looks back to the scene at that, watching the man bob his head back and forth.

"Then what is happening?" He asks, and Ace hmms in contemplation.

He obviously knows what they're doing, But… How should he explain this, to Luffy who apparently can't connect the dots, and have apparently never heard of a damn blowjob before?

Ace remembers the start of the scene, weren't the two of them kissing? Or at least, violently making out?

"Well… It's.. Like, kissing?" He says aloud. He feels really awkward right now, for more reasons than one.
Ace is a sexual guy, has always been, has been with a lot of partners before with great diversity and is pretty chill about it. So, it's no surprise to him that… Some parts of his body are reacting to the porn on full display.

"Like kissing?" Luffy echoes.

"Yeah. Like, kissing is a thing you do with people you care about right?" Ace says, trying to explain.
Luffy's eyes widen and get that excitable sparkle to them.

"Ah! So there's another level to it!
Like how kissing people on the forehead, cheek and nose means you care, and kissing on the lips means you really care! Then is kissing like they did maybe the next level? Ah, but Makino said that you only kiss special people on the mouth" Luffy rambles on with Ace's idea, who nods at him as he talks. He's on the right track, at least.

"But wait, why kiss there, then? Have I been kissing people wrong all this time?" Luffy wonders to himself, Ace remembers that his brother would kiss people goodbye on the cheek as a kid. He thought it was their mother who'd taught him that, but from the sounds of it, it must've been Makino, their old babysitter.

"Okay no.. it's not something that's so set in its ways, as no one would do it completely the same way. Maybe it's more like… there's multiple ways and we all have one we like the most?" Luffy says, and Ace wonders briefly if his brother's gotten a brain tumor or something. Logical Luffy are few and far between, after all.

"You're right, actually" He says and Luffy flashes him a huge sunny smile, before scooching closer to Ace.

Seeing the recognizable glint in his brother's eyes, he watches as Luffy reaches out for a hug.
He's surprised though, when his brother's lips meet his own.
He scootches back in surprise, but Luffy follows him and kisses him again, settling between his legs as Ace's brain short circuits.
His brother's lips taste slightly minty, likely from some gum he'd chewed earlier, they're soft and a little wet.

Ace's dick twitch like the traitor it is in his pants.
Which makes him really want to cut it off because What The Fuck-

His brother pulls back as soon as he came close, and Ace watches Luffy's unsatisfied pout and thinking eyes.
Ace's own wide eyes take it in, still trying to catch up to what just happened.
He can still taste Luffy on his lips. His brother's still close enough that he can feel his exhales on his face. Luffy's brows furrow in deep concentration.

Luffy leans in again, and Ace isn't prepared for his mouth being slightly open, but autopilot takes over as he matches up quickly and opens his own in turn.

This kiss is.. Longer.

It also feels pretty good, if he's honest. Leaning against the armrest, he pulls Luffy closer, his brother understands the idea right away, and crawls onto Ace's lap. Ace's arms encircle Luffy's waist, he feels the others arms land on his shoulders.
His brain must've shut off, flesh jellyfish with electricity went 'bye' and took a trip downstairs it seems.

They don't break the kiss, in fact, Ace thinks it gets more heated the longer it goes on. Luffy's mouth opens a little wider, and Ace feels his brother's tongue trail his lower lip. He gets with the program and meets him with his own.

The fire in his veins feel like it's going to erupt at any point, pooling between his thighs in an unfamiliar, but good - very good - sensation.

Luffy breaks the kiss after what seems like minutes, he's smiling and has a satisfactory look to his eyes. Ace smiles back in turn. Brain still not online, operating completely on autopilot, and instead of jumping from the window in disgust, he does what he always does after a playfight or a hug.

"That was good!" His brother says and Ace lifts an arm to ruffle his hair.

"Maybe that's the point?" Luffy asks no one but himself. Ace blinks and waits on him to continue, forgetting the point to all of this.

"Kissing, hugging, talking, it all feels good right?" He nods.

"Well what if that's the point? Doing this stuff with someone you care about, so you both feel good and have fun?" He says
A treacherous part of his brain agrees that this is what they're doing. It's innocent. He's a little surprised Luffy came up with it.
Ace smiles and nods, he likes that idea, nothing makes him happier than the thought of making luffy, his baby brother, feel good and content, happy.

"Then let's make sure to do a lot of feel good stuff together, Ace!" Luffy says, before diving back in, barely giving him time to prepare for another kiss.

They pull apart again after a while much like the last kiss, this one just as heated. Luffy looks down, before meeting his eyes again. He's got that determined look to his eyes that Ace reads as 'trust me'.

Ace silently conveys that he'd trust Luffy with his life.

Luffy's hand reaches down to the front of his pajama pants and presses slightly. Ace's breath hitch in his throat in surprise.

"Does that hurt?" Luffy's eyes flash to his. He hasn't removed his hand.

Ace shakes his head no.

Luffy's hand presses firmlier, before rubbing in a slow up and down motion.

Ace can't hold back the sound his throat makes.

His brother catches his eyes, and he shakes his head again.

Luffy goes in for another kiss, Ace accepts with open eyes and let's his arms go from his waist to his shoulders. As Luffy's hand adds pressure and increases the speed of his rubbing, Ace's involvement in the kiss becomes sloppy, at best.

Luffy pulls back to survey his brother's face, it's flushed red, lips glistening with spit and his eyes look darker than normal.

Making up his mind, he steps off the couch, his hand fisting Ace's pant leg, gesturing for his brother to turn as well, his legs on the floor. Luffy, sitting down between them with his knees between Ace's feet.

Luffy can hear him breathe heavily. Gripping his brother's waistband, he tucks the pants and boxers down in one swoop to let it pool by his ankles. Ace's eyes widen, but he doesn't move to stop him.

His hands slide over his brother's thighs, spreading them a little wider to make room for himself. He sees Ace's dick twitch at every hot exhale. Reaching out tentatively, he touches Ace's still standing erection, firm pressure in hand.

Ace gasps beneath him, and he looks up at the wide eyed flushed face of his brother.

"Tell me if it hurts at any point, okay?" He says, seriously. He doesn't continue till Ace nods.

Opening his mouth, he lets his tongue glide slowly up the shaft. He gives the head a little kiss, before taking it in.

'It's salty, but not bad.' Luffy thinks as he imitates the man from the screen, sucking the member deeper and deeper, till he's nosing at the nest of black pubic hair.

Going back and forth, he establishes a rhythm. Opening his eyes, his gaze goes up and lands on his brother's face.

Ace's mouth is hanging open slightly, his face is completely flushed with small beads of sweat glistening on his forehead, black hair clinging to it.

Their eyes meet, and Ace's gaze is intense, so intense that Luffy feels like Ace is about to completely devour him with it alone.

Luffy would let him if that's what Ace wanted.

He speeds up his rhythm and tries to apply pressure with his tongue, but he doesn't close his eyes again, instead trying to keep eye contact with Ace.

Ace feels like he's on fire.

And somehow the gaze of his little brother intensifies it, he feels like molten lava is burning up his organs, pooling by the base of his spine and deep in his stomach.

And he likes it.

Watching as Luffy bops his head up and down, spit drooling from chin and drying on his hair and thighs, and somehow Ace has never felt this.. Connected to his brother. He feels an overwhelming need to embrace him till his spine cracks, to tear him open so he can drink his insides, and Ace doesn't know or understand what to do with it as he drowns in the dark pools of Luffy's gaze.

He should have stopped them coming to this point, but his mouth didn't move and his body was screaming at him to stay put.

When Luffy decides to try and swallow at the same time, Ace feels like he blacks out for a minute, and his brother seems to notice as he makes a Hmm? , and Ace can't stop the way his legs and thighs shake.

As the pace speeds up again, Ace feels a bunch of sounds force themselves out of his throat, he almost feels like howling in pleasure. He can't believe something could feel so good ?

He resists closing his eyes, not wanting to lose eye contact, the heat feels like it's going to erupt while gathering simultaneously together between his thighs and stomach.

When Luffy's tongue applies more pressure and he feels a gentle, so gentle, scrape of teeth on the underside of his shaft, Ace's vision completely whites out as all the heat forces itself to explode.

He's pretty sure he forgets to breathe.

When his vision clears, he sees Luffy lick his lips, hands on his thighs and an audible swallow.

There's cum drooling from the corner of his lip.

Ace feels himself twitch slightly at the sight.

Still trying to catch his breath, he reaches out with a hand and places it on Luffy's own, the heat of it helping his erratic heartbeat start to calm down.

"How was that, Ace?" His brother asks, licking his lips before reaching out with a thumb and removes the cum, sucking it into his mouth.

"That was.. Really really good, actually" He says and Luffy's eyes light up. A broad smile stretches out on his face.
He doesn't know why he was honest. Doesn't want that to be the truth, either.

"Really? Great! I'm glad you felt good Ace! That makes me feel good!" Luffy says, before getting up. Ace would follow him, he feels a deep need to touch his brother and be close, but he's still catching his breath.

Luffy comes back shortly after with what looks to be a wet washcloth in his hands. Before he can start cleaning up what Ace guesses is his thighs, he reaches for it.

Luffy lets him take it easily, and with his other hand he guides Luffy to sit down in front of him again. With a hand on his chin holding his face, he wipes his mouth, cheek and chin down with the warm cloth. Luffy smiles and snickers at him.

After that he gives him the washcloth back, and Luffy cleans Ace's thighs, carefully wiping away spit and some of the cum that had run down Luffy's chin. He then pushes his brother's pants back up, before going back into the kitchen and throwing the wet and now dirty cloth into the sink. He rinses his mouth quickly with tap water (that white stuff wasn't tasty) before going back to the couch. He's about to sit back down where he sat before, but Ace, who had moved while he'd been to the kitchen, grabs his wrist and guides him to lay between his open bent at the knee legs.

Doing so, he uses his brother's chest as a cushion. It's nice and comfy, he wouldn't mind doing this more often. Ace's arms encircle his waist, and Luffy picks back up the remote to continue his channel surfing.

But not without committing the previous channel number to memory.

He wants to learn more feel good stuff to do with Ace.

(slight time skip)

Over the course of the month Ace's thoughts had been consumed by images of Luffy.
It doesn't help that since the 'blow job incident' as he'd dubbed it in his mind, Luffy'd been more touchy-feely than he usually is.
And, one evening, it happened again. Luffy had been in a weird mood and came to his room in the middle of the night. At first, Ace had guessed it'd been a nightmare, but then Luffy kissed him, waking him up completely.
There, Ace had been the one to give Him a blodjow.
He hates himself for it, because the sounds of Luffy's groans haunts his mind.
But he Likes that it does.
He enjoys the thrill of it, and has even Begun to look forward to Luffy popping in at random instances during the night. And he almost always blacks out feeling overwhelmingly good whenever Luffy uses his mouth and bites his inner thighs.

Luffy on the other hand never thought of it, not in the wanting sense, more factually. He really enjoyed doing the feel good stuff! But he discovered that while Ace is quick to enter what he'd dubbed, the feel good mood, Luffy… not so much.

Luffy mainly enjoys making Ace feel good, but when Ace returns the favour and makes him feel good too, that makes him happy.

Luffy likes it rough and fast paced as well, but he also really likes a slow pace with good pressure and kisses. Lots of kisses. He really likes being kissed on his throat. Ace bit him there once, and he really enjoyed that.

So, since it'd been more than a month since they started, Luffy decided to venture to that channel again, in hopes of learning something new.

Turning on the tv, Luffy quickly clicks to the right channel.

This time, there's three people in various states of undress. One of them is a woman, the other two men.

One of the men, a brunette, opens his mouth to talk.

"Are you sure your boyfriend wants to join?" He asks the woman.

Luffy wonders if his assessment was wrong. They both look like boys to him, but the man states it like there's only one. Izou once told him not to judge people based on their looks, and that there's more to people than boy or girl. He's glad for that, now it makes more sense.

The woman who's only wearing underwear beckons the other person over, the assumed male friend of hers.

"He will" She starts, "In fact, I'm dying to see you two going all out and have sex with each other"

Ace enters the living room. Luffy continues watching.
When Ace stumbles upon his brother watching porn, a part of him is thrilled all the way down his spine.
Another part wants him to call Sabo and their parents and ask for them to arrest him.
If their blonde brother found out…. He'd so kill him.

Ace would probably let him.
Yet, for some reason, instead of picking up the phone he sits down next to Luffy who's paying full attention to the screen. Ace tries to stay as neutral as possible.

The two on the screen go along with it, the man and brunette start kissing each other as the woman watches, her hands gliding up and down her body.

Ace looks to the side at Luffy, he can tell his brother is watching with slight interest and slight boredom, likely waiting for something new to happen. Ace looks down at himself, staring at his once again treacherous penis. It doesn't help that watching those two on the screen, his brain automatically transcribes it as himself and Luffy instead. Yeah that doesn't help at all.

Knowing the differences between himself and his brother, how luffy didn't think about it to feel good, he did it because it felt good and Ace enjoyed it, and that was that.

As it goes on, Ace starts to pants feel tight and suffocating, and his hands itch to relieve himself. His eyes follow his brother's chest movement as he breathes, and he wants to touch, to kiss, to lick his body.

If Luffy notices his slight restlessness, he doesn't say anything.

Finally, the woman moves. She goes to sit on a bed along the headboard and she asks them which one would prefer to be bottom out of the two, she'll 'fuck' them good and rough' (those were the words she used) but only if they fuck each other first.

The brunette says he's fine being on bottom. The man grins and gestures to the bed and the brunette lays down stomach facing up, legs bent at the knee with feet planted on the mattress. The woman throws off her underwear and watches them.

The man starts off by pulling down his and his partners pants, before sloppily kissing thighs and taking the standing member into his mouth. The woman gets up on her knees to go to a drawer besides the bed. From there, she hands the man a clear tube.

Then she sits on the brunette's face. Luffy wonders if she's trying to suffocate him.

The man lifts one of the brunette's legs, hoists it onto his shoulder, before he opens the tube and squirts some thick.. Goo? Out onto his fingers. It's also clear. Luffy's kind of reminded of toothpaste.

The goo-covered hand trails down to the brunette's butt, sliding down between the cheeks. Luffy is now paying full attention. This is something he hasn't seen before.

The camera filming all of this zooms in on the view of the tight red ring of muscle, a single finger circling it with the clear goo on it, before slowly entering.

Zooming back out, you hear the person grunt. The woman is also being loud, but he's ignoring her.

The man starts a rhythm, slowly pulling his finger back out before pushing back in.

After a while, he inserts another coated finger. The person grunts some more and the man pauses. He's waiting for something, it seems like. When the person's hand gives a thumbs up, he starts the rhythm again. The woman reaches down to take the member into her mouth, making it go back to full hardness quickly. The brunette's sounds of pleasure become more evident now that she's not completely covering their face. Luffy still wonders silently what was up with that.

When the man adds another finger, even more carefully than before, the woman slips off the brunette who hisses. The man pauses, waits for a moment before the brunette nods. The man picks up the rhythm, the woman, sitting by their sides, reaches out again and strokes the brunette a couple times till the sounds restart.

The brunette says he's good and to go ahead, the man nods and the woman is watching.

He then lifts a leg up on his shoulder and settles between them on his knees, the woman hands him a pillow that he places beneath the other's hips. He squirts some more of the clear lotion to his dick and slowly starts to insert it into the brunette's ass like he did his fingers. B There's grunts and the man stops as he's completely balls deep, then waits a moment, till he's gotten a nod, and then he starts moving back and forth slowly.

The brunette makes more 'feel good' sounds, and the other starts to speed up, they seem to enjoy that, and soon after the white stuff comes out from both of them, though not the woman. She says thanks for the cum, which Luffy assume is the white stuff,some more stuff happens but Luffy turns off the Tv at that, then he looks at Ace.

"What do you say, Ace? Should we try the sex?" He's pretty sure he remembered correctly. Ace doesn't correct him at least.
His brother hesitates.
"Look, Loof… I'm Not sure we should do that"

"Ace doesn't want to?"

He hesitates again, and Luffy can tell. His brother wants to, really wants to. But something's holding him back from saying yes.
"Is.. What we've been doing a bad thing, Ace?" He asks, because the freckled man has that look of guilt in his eyes. He flinches.

Luffy feels a bit of anger in his veins, because he doesn't believe that.

"I don't care if it's a bad thing! I like it, I enjoy doing all of this with Ace!"

Ace sighs and looks away.

"It's not something we should do, we're brothers. This is something you do with special people Luffy. Like a husband, wife, partner, whatever. Do you get it? Why we shouldn't be doing this, flesh and blood?"

"No."

Ace's hand makes a smack as it lands on his forehead.
"I don't care! I want you to sex me, Ace! And besides, you Are special! Ace is my most special person in this whole world!"

He snorts.

"I'll tell Sabo you said that, and Mum and the dads"

"Well they're also special to me!"

"So you would do this with them, too?"

Luffy doesn't answer right away.
Somehow, there's something there that makes him hesitate.

He loves their parents, with all his heart. He loves both his brothers, yet there's always been.. Something, with Ace. How it felt like the man just knew him better than himself, that made Luffy feel more secure with him in the long run.
Sabo he could always count on, but Ace had almost always ensured he didn't need anyone to count on.

"No, only Ace"

His brother's eyes search his.

"Do we have any clear lotion?" Ace asks his brother. Luffy pauses for a moment, mentally going over a catalogue of existing items in their house.

"Yeah I think so. Hold on," Getting up from the couch and into the bathroom, he looks through the drawers. If he remembers correctly, then they Should have vaseline somewhere.

His search quickly ends when his fingers connect with the flat surface of the transparent bottle.

Making a sound of triumph, he walks back to the living room.

Raising his hand and showing his find, Luffy smiles a toothy grin as he realises what this means and runs ahead towards Ace's bedroom.

He's not sure if the sex is only do-able in a bed, but for a first time it's probably the best choice. They can always try out different stuff later.

When Ace enters his room, he finds Luffy already on the bed.

He's laying in the middle, shirt discarded somewhere, only in boxers and with a pillow beneath his hips.

Seems like Luffy decided he's going to be the 'bottom' on this first try.

He's not surprised, his brother's made it his job to make sure it's 'feel good' enough for them to do it - Ace suspects he doesn't want to hurt him by accident, and respects that.

Even if it is frustrating sometimes.

He sighs good-naturally and smiles at his idiotic little brother.

Luffy, as if reading his mind, snickers unapologetic. What a brat.

"Right then. Let's get you in the mood." Smirking back, Ace removes his own shirt and ´pants till he's in a similar state of undress like Luffy is. He puts the vaseline on their nightstand for now, letting his fingers trail from a defined collarbone down to grip him at the waist.

His other hand traces Luffy's chin, guiding it towards him as he places a kiss on his slightly parted lips.

Letting his hand roam, his fingertips touch the skin of his inner thighs. Ace deepens the kiss, letting their tongues meet in a dance.

His fingers slowly trail upwards to his more than not interested form of his little brother. He rests his hand between his legs, applying a thin stroke of pressure before delving into his boxers.

He breaks the kiss. He mouths down his jawline, tongue cascading further downwards. He can feel Luffy's pulse as it's speeding up.

Smirking against the warm skin, Ace leans further down. Placing small nips here and there, enjoying the way Luffy makes sounds of pleasure from it.

He pulls off his brother's boxers, one hand stroking him slowly. He noses the dark nest of curly hair before giving him a tentative lick. He knows he doesn't need to go this far to bring Luffy into 'the mood', but watching the way his brother reacts is enjoyable, too.

Plus, he wants him to feel good.

"You ready, Luffy?" He asks. Luffy's face is a little flushed, it makes his scar stand out.

"Yeah" Ace doesn't waste any time grabbing the vaseline. Clicking it open, he gently guides Luffy's leg further apart so he can sit there comfortably. He checks to make sure the pillows still place nicely, before dipping a finger into the clear gel.

Slowly bringing his covered finger to the ring of muscle, he circles it before pressing gently.

Luffy stays relaxed beneath him and the finger goes in smoothly.

He waits, keeps eye contact with his brother. Luffy gives him a go ahead gesture, and Ace mimics the slow goings the in-and-out motion they saw earlier.

He spits in his other palm before taking his brother in a gently but tight grip. Luffy's breath deepens.

"I'm adding another finger. That alright?" He gets a nod. Carefully he pushes in a second digit, watching his brothers face for any discomfort. Ace's other hand starts stroking slowly, he's rewarded when Luffy fully rehardens. He resumes his motions, curling his fingers here and there and watching as Luffy's face deepens it's flush. He watches as sweat gathers on his brother's forehead and neck, watches a droplet of spit slowly flowing down by his chin.

He feels compelled to reach out and lick it, but also thinks that's a little gross.

Instead, he adds the third and last finger. Luffy makes a quiet grunt of discomfort, so Ace goes down and takes him in his mouth while waiting for his brother to adjust or break it off.

"Go ahead and move them"

Doing as told, Ace carefully resumes his previous hand motions, still curling his fingers.

He changes his wrist movement, and suddenly the hips beneath him stutter violently enough for Ace to let go so he doesn't choke.

Looking up at Luffy, he meets his brother's eyes. They're darker than the depths of the ocean, and Ace wants to breathe it all in.

"That. That felt good" He says and Ace commits the movement to memory.

He does it a couple of times with a flick of a wrist, and each time Luffy gasps out loud.

He feels like getting drunk on those sounds.

Pulling his wet fingers out and throughrougly ignoring the sound it makes, he discards himself of his boxers. Using the remaining vaseline on his hands, he covers himself heftily. He also takes some extra from the clear bottle, just in case.

Getting back between Luffy's legs, he mimics what they saw earlier and lifts one limb to hang from his shoulder, feeling the heel of Luffy's foot on his back.

Lining up, he takes a deep breath before slowly pushing in. His other hand lazily stroking his brother while inch by inch disappears inside of him till he's fully inserted.

Staying still's a lot harder than he expected, he feels like he's surrounded by a wet warm, so warm, and constricting heat and it fills him with the need to move-

But he stays still. Hand doesn't stop stroking Luffy as he waits for his brother to give him the go ahead.

"M..Move" Is said between breaths, and Ace slowly pulls out about halfway before pushing back in, keeping up a steady rhythm.

Letting go, his hand goes to steady Luffy's hip, the other still holding onto his leg.

Heavy breaths fill the room, the atmosphere feels like a low static laying in wait, wanting to strike at any moment.

He speeds up slightly, and pulls out nearly all the way before pushing back in. Luffy's legs spread further as his leg encircle Ace's own hip. Adjusting the angle between thrusts, he waits for that tell-tale twitch of his brother.

Luffy grunts hard, a grating sound in his throat as he finds the right point. Smirking, he makes sure to only thrust in that direction, speeding up some more.

He meets his brother's eyes, they're dark with something Ace doesn't know what to call and glazed over. Dark hair plastered on his glistening skin, mouth hanging open.

Ace wants to lose himself in the sight.

Luffy's arms, which had been laying above his head, move with grabbing motions towards him. Ace snickers, getting the hint and lets go of his leg before he leans down and covers his brother's torso with his own.

Hands grasp his back, the delightful stinging from short blunt nails makes him bite his lip.

Speeding up, but still in that same direction, he begins to feel that tingling sensation starting by his feet, crawling up his legs leaving goosebumps in his wake.

He wonders, and hopes, Luffy feels the same beginnings of climax build up.

Keeping it up, the scorching lines on his back makes him thrust harder. The sounds from beneath him edges him further on, till his rhythm and pace becomes erratic and he fills that hurricane of tingles clawing his thighs, makes his muscles contract and breath stop. Grunting, he tries to keep going as he climaxes, snaking a shaking hand between them and stroking his brother hard and fast.

It doesn't even take more than a couple twists for Luffy to be spilling all over his hand with a shaky exhale himself.

Letting go, he stays where he is, hovering over his brother's flushed face, who's eyes had shut during the end as his plaid mouth hung open.

He kisses him on the nose. Luffy's eyes open and blink a couple times, likely to focus, before a blinding smile makes its way onto his face. Ace answers with a smile of his own, snickering, he leans in to kiss his brother's smiling mouth, playfully biting his lip.

He makes a scandalized sound before laughing at Ace. That's truly one of his favourite sounds in this whole world, it fills up his chest cavity with warmth that nothing else can. He laughs too.

He slowly pulls himself out of his brother, also ignoring that sound, before standing up on shaky legs.

"Let's go 'n shower, alright?"

Luffy joins him excitingly.
