Law wishes he could blame inebriation when his mouth opens and says, “Yeah, it’s true.”
The damning confirmation has the Straw Hats looking at him in a way that makes Law really wish he could jump into the ocean and swim to the safety of the Polar Tang.
How did they even get here?
Law was making his way back from the Lavender Sea when the Polar Tang ran into a nest of Sea Kings. They made it out relatively unscathed, but there was a bad scrap on the hull of the metal that ran the risk of tearing and letting sea water in.
It was pure luck that the Straw Hats happened to be docked in the island next over. Franky had readily agreed to help patch up the submarine with Jinbe’s help, a curious Chopper and Usopp in tow. Nami had followed after, an accounting book in hand and a wicked grin leveled Law’s way that made Law understand the navigator was going to clean him dry.
The rest of the crew had gotten comfy on the deck of Sunny, Law unfortunately perched right beside Luffy, practically in his lap. It was Brook that brought out the music and Zoro that brought out the alcohol and Law was distressingly aware it took little for the Straw Hats to find a reason to party.
Though while they waited for the rest of the crew to finish up and join them, somehow – it’s 100% Blackleg-ya’s fault – they started talking about sexual history.
Law is still trying to figure out what the shiver down his spine meant when he learned that not only does Luffy know what fucking is, he apparently has a voracious appetite. The crewmates seemed to share a telling look between each other when they lingered on the alpha prowess.
“Luffy’s the only dynamic on board,” Robin had offered, a knowing smile on her face.
Sanji, needing no other prompt had stated, “It’s a good thing we don’t have an omega. Luffy would never let them leave the bed.”
And that had started the dangerous heat in the pit of Law’s stomach.
“Whaddya mean?” Luffy had asked, head cocked to the side in innocent curiosity. “Sex is fun, but there is more to life than that! Like food!”
Zoro had snorted into his ale in the type of laughter that Law has rarely seen the fierce warrior with. Even Robin had been smiling indulgently while Sanji and Brook seemed to share identical smirking grins.
“But that’s the point,” Sanji said, grinning mischievously. “Omegas are supposedly delicious.”
Luffy had blinked, wide eyes confused. “People aren’t food, Sanji.”
That had Zoro howling with laughter while Sanji tried to murder the First Mate.
Brook had stepped in, leading to Law’s doom. “What he means, Luffy-san, is that omegas produce a sweet nectar when aroused. It’s highly addicting to alphas.”
And then, Luffy had turned to Law and the look on his face had completely caught Law off guard. “Is that true?”
And Law, heart pounding, opens his mouth and damns himself with the words, “Yeah, that’s true.”
So, here they are, Luffy looking at Law with a hungry glint in his eyes. “Can I try?”
Sanji snorts, waving his hand as if Luffy is talking to him. “Give it up, Luffy. Omegas are rarer than alphas.”
Both Zoro and Robin turn to look at Law. Sanji’s wistful air pops as he catches on, jaw dropping, even as Brook says, “Oh ho?”
Luffy repeats, “Can I try?”
Law always keeps diligent track of his heats. Amber Lead took a lot away from him and the Ope-Ope no Mi could have taken more, but this is one thing that’s stayed. Law never minded his heat, categorized it as its own bodily function to be kept in privacy just as Cora-san had taught him. No one knew that Law didn’t want. That meant no one could take or ask for it.
It also meant Law has no idea what it means for him. And damnit if he isn’t a little curious.
Luffy is a lot of things to Law. The bane of his existence. His friend. The man Law not-so-reluctantly calls the Pirate King. He is also someone Law fully trusts.
So, he licks his dry mouth and rasps. “Yeah.”
Luffy grins, the same look in his eyes that Law has seen hundreds of times before. The fun of adventure. The thrill of something to be conquered.
Shivering, Law lets himself be led by the man to his chambers, cat-calls following in their wake.
_
Luffy is nearly seven years younger than him, but he takes control of Law’s unease with the experience of someone double his age. He settles Law’s jitters with firm and grounding touches, keeping Law from thinking too much with soft, playful kisses and wandering hands. It’s frustratingly effective, but Law has never been one to hold on to prideful pretense. He can count on one hand the number of people he will allow to touch him. That number does not allow for a lot of sexapades.
Fortunately, Luffy is now on that list of ‘touch is okay’. Fast on the list-of-one where ‘touch makes me feel good’.
By the time Law’s naked and comfortable enough to spread his legs, Luffy’s been praising Law for how good he smells and how he wonders what flavour Law will taste like.
“Ne, Sanji said once that omegas can make milk,” Luffy says, a mischievous look in his eyes as he stares up at Law from where he has his mouth hovering over Law’s puffy nipple. Luffy has spent far too much time teasing him there.
Law glares, eyes a bit hazy with lust. “Omegas make milk for their mate and family,” he corrects, voice breathy, because fuck him if his stupid medical background won’t allow half-assed knowledge fly free. “Is that going to be a problem?” He’s reminded, once again, that Luffy is treating this as a food experiment. Maybe he should –
“Nah,” Luffy says, lips wrapping around Law’s nipple in a way that has his back arching hard. Luffy sucks him until Law can’t remember his irritation and then says, “It’s a challenge.”
(And Law has also discovered he may have a thing for that cocky look in Luffy’s eyes.)
“Hurry up,” Law finally breaks. He doesn’t quite beg, but his tone has a pleading note to it. He can smell himself and Luffy’s arousal mixing in the air and it’s making him heady.
Law is on edge, lust buzzing under his skin and begging to get on with the promise of pleasure. But Luffy, the normally impatient minx, refuses to pick up the pace, alternating between commenting on how pretty Law is and leaving marks and bites all over Law’s body until he’s a trembling mess.
“Shishishi,” Luffy laughs, leaning back from where he straddles Law to give him a grin. Luffy is a solid weight for his small stature, and it’s also ticking the list of things Law likes that Luffy does to him. “Are you ready?”
In answer, Law bucks. His erection slides over the cleft of Luffy’s naked ass. “Hn,” Law whimpers, a spark of pleasure stuttering down his cock. He bucks again but Luffy clamps down, keeping Law pinned.
“Okay, okay,” Luffy laughs. “Let me - ”
Embarrassment pools deep in Law’s stomach, simmering along with his arousal, as Luffy grabs Law’s thighs and spreads them wide, settling in between them.
“I - ” Law swallows hard when Luffy looks up at him from where he had been intently staring at Law’s groin, completely wet with slick that is practically shines in the dim light. “I can turn around.”
Gods, he must be completely red all over. He feels so disgustingly vulnerable but the only thing preventing him from bolting is Luffy’s easy countenance.
“I wanna see your face,” Luffy rejects with a pout.
His hands tighten on Law’s thighs, and Law gasps when the man bends them back, nearly folding Law in half. The new position has Law’s ass in the air, erection bobbing close enough to his face that a stray speck of precum falls right on his collarbone.
“You’re bendy!” Luffy says approvingly, when checking to make sure the position isn’t stressing Law out. “Hold your legs open for me.”
Law can’t think of any retort for that, heart in his throat. It’s all too much and not enough and Luffy luckily always know when to dive right in when Law is hesitating. He guides Law’s hands and then gives him a cheeky smirk, head diving down.
“Lu - Hnn!” Law cries out at the first broad swipe of Luffy’s tongue over his hole. It’s a sensation Law has never experienced before – hot and wet and firm, but only for a second, there and gone. Law immediately wants it back.
“Mo - ” Law doesn’t need to say more as Luffy immediately dives back. He nudges up, actually bending Law in half – his knees are by his ears – hands prying Law’s asscheeks apart with a bruising grip, spreading them wide to bury his face deeper.
It’s messy and humiliating. Law’s face is so red he can feel how hot he is. But nothing in the world can stop him from whimpering for more. His erection bobs, aching from being untouched but Law can’t spare a thought to it. He can only watch with half-lidded eyes each flick of Luffy’s tongue, greedily lapping up all the slick Law can’t stop creating. He’s so aroused, juices and saliva that Luffy doesn’t catch in time dripping down his ass. Law doesn’t think he has ever been so wet.
“Please,” Law gasps, mind a haze. “Luffy!”
Luffy makes a rumbling sound, deep in his throat, that has Law answering in a keen.
“Torao,” Luffy huffs once he’s cleaned up all that he can, looking down at Law with slick-spit all over his face, eyes completely blown, “you taste so good.”
Law’s answer is another hiccuped moan, entire body trembling at the way Luffy’s aroused voice sounds.
“More,” Law replies in answer, unable to say anything else.
Without needing to be told a second time, Luffy dives in. This time, he concentrates on Law’s sensitive hole.
“Ah – Ah!” Law tries to stifle the needy sounds, but he only sounds more vulnerable. If he wasn’t so busy holding his legs open, he might stuff his hand over his mouth to stop the embarrassing cries, but he can’t spare the thought to do it.
So he’s stuck, grip fast becoming white-knuckled and bruising his own thighs, as he keeps himself splayed open for Luffy as his tongue makes another pass over his rim. A string of high pitched whimpers escape him though as Luffy points his tongue, probing Law’s hole with wet enthusiasm. Despite how messy it feels, so primal, there is skill there, Luffy slowly working Law’s hole open until he can get his tongue inside.
It’s so sensual, the thick press of something nimble but firm licking his bare insides. Luffy is making good on eating him out, tongue freely sliding in and out, the audible noise of Luffy swallowing Law’s slick and going back for more pushing Law close to the edge. Law’s entire body feels too hot and he can’t think, can only focus on the feeling of that plaint muscle fucking into him again and again, steadily loosing Law’s rim and getting deeper to get all his sensitive flesh –
Without warning, Law’s orgasm crashes over him. His cock pulses and then ejaculates, cum covering Law’s face for a second before he drops his legs. It’s instinctive, the way he clamps his thighs around Luffy’s head and his hand fists in his hair, the other slapped over his mouth, to barely stop the lewd moans Law can’t keep to himself. His peak lasts forever, gut roiling as his nerves sing. He can feel himself spasming around Luffy’s tongue but the man doesn’t stop.
Finally, Law goes limp, legs falling from Luffy’s shoulders to fall open and vulnerable around Luffy’s hips. He pants, chest concaving as he rapidly tries to get his breathe and senses back.
The first thing he notices is Luffy’s face bottom half gleaming in the lamp light with slick coating it.
“Law,” Luffy says, and Law moans because Luffy hardly ever says his name correctly, “you are delicious. More than any meat. Almost as good as Sanji’s cooking - ” Luffy cocks his head, tongue absently licking around his swollen lips to chase the taste. Law can see Luffy’s dilated eyes, can smell the heavy arousal wafting off the alpha. “I want more.”
Law shakes his head because he doesn’t know what he can give Luffy right now. He feels like he’s hanging on a razor wire on top of a bottomless pit. He doesn’t want to admit he likes it there, the thin feeling of lack of control and excitement because he wants more too new.
“If you want me to stop,” Luffy says, leaning over Law, stretching just a bit so they can be face to face, and then he licks the cum off of Law’s chin, “just say so. But until you do, I want to have more. And this time, don’t you dare hide your voice.”
Law’s gut punched with arousal by how matter-of-factly Luffy says he’s going to take what he wants. Law hates feeling put down or patronized or taken advantage of, but with Luffy, it’s not like that. Law trusts him. So when Luffy goes down and picks up Law’s legs again, Law lets him.
“At least let me help you - ,” Law tries to say, but Luffy already ignoring him and Law’s words are cut off with a yelp as Luffy’s tongue licks up Law’s ass.
“Luffy - ” Law tries again, when he finds a moment to breathe through the stimulation. But, like it’s a game, Luffy starts spiraling his tongue inside Law and all words fly out of Law’s mind and only sounds of pleasure come out his throat.
Luffy’s impatience begins to show because he leaves a thigh to wrap his hand around Law’s cock. It makes Law jerk, crying out and entire plan to muffle his sounds thrown out the window as one hand fists Luffy’s hair and the other fists the pillow behind him as he tries to ground himself from the surge of pleasure.
He comes again like that, a breathless moan taking up the space in the room, tears in his eyes from overstimulation as Luffy’s wicked tongue licks over his cock head.
“You’re salty here,” Luffy informs him, cleaning Law’s spend. Luffy’s thumb works tight circles around Law’s hole as if to keep him open. He hooks it inside Law’s hole and pulls to the side and says, “And you’re sweet down here. I like it, Torao!” then Luffy laughs, a beautiful thing as if he isn’t hard as a steel pipe and wafting pheromones of ownership all over their cabin.
“Glad you do,” Law barely manages to say, reeling from his second orgasm. “Now can you let me touch you?”
Luffy hums in thought and Law shivers, seeing the dilated want in Luffy’s eyes. Sanji’s words float through Law’s mind – but surely Luffy wouldn’t actually pin Law to the bed just to eat him out for hours right?
“I still want to taste you,” Luffy denies and Law’s stomach falls but he can’t be sure if that’s arousal or fear. No, not fear – he knows Luffy would stop. Knows he could stop Luffy. So it must be –
Law’s cheeks flush because he doesn’t like the idea how pleasing it is to him that Luffy can’t get enough of him.
Just a taste thing, he reminds him. Luffy would like any omega –
“And you’re so pretty,” Luffy continues, easy grin on his face as he leans up again to mark Law’s neck. It puts his lips close to Law’s ear and it makes Law come undone when the younger man says, “I like how good you look in pleasure, Torao. I like I made you feel like that. Give me more, okay?”
Law’s entire face feels as red as volcano. He can smell his own slick this close and it should be disgusting but something primal inside him is preening at how Luffy is drenched in his scent.
“Okay,” Law can only manage.
The third round has Law’s hips flexing on their own accord, practically riding Luffy’s face with shameless abandon. His cock is starting to tire but it’s like his ass is only getting readier the more Luffy plays. Now he can’t stop thinking of what it would be like if Luffy’s tongue was his cock -
“Luffy!” Law’s breath catches, thighs shaking as Luffy practically slurps him – no, it shouldn’t be this hot but Law feels the fire in his gut getting bigger again, but it’s different he feels looser, wetter, and there is a different coil of pleasure in his gut and Law doesn’t know what it is. “I – I, give me a second, Luffy-” Luffy doesn’t, fucking his tongue into Law’s ass with a vigor, unrelenting even as Law feels everything start to sharpen with the pleasure of an orgasm. “I think I’m cum - ”
It’s mortifying the way everything just suddenly feels too wet, like a dam bursting.
Luffy moans – he’s been making happy sounds of pleasure the entire time but this time it’s deep, unbridled and wanton – and latches his mouth over Law’s hole as Law squirts.
“No more,” Law begs, feeling untethered from such an unfamiliar and body wracking climax. He can feel his inner walls clamping and clenching and it burns Law to know his body’s omega walls are trying to milk a knot that isn’t there. “Luffy, I can’t -”
“You can,” Luffy tells him and Law’s words die on his tongue, overcome by a wave of primal need at how low and needy Luffy’s voice sounds. Finally, Luffy is losing control. His erection ruts against Law’s thigh, leaking as hard and wet as Law practically is. “I want to eat you out all night, Torao. Can I?”
Law shakes his head, hand over his mouth. ‘Stop’ is on the tip of his tongue, but he doesn’t really want to. He wants to feel more of Luffy, over him, in him, under him – wants to see the pleasure on Luffy’s face and know with satisfaction he put it there.
When did he get so bad at denying Luffy?
Luffy takes his consent. This time, he flips Law over gently and stuffs pillows under Law’s pelvis. One hand grabs Law’s and squeezes tight. “If you want me to stop, tell me,” he repeats again. He barely waits for Law’s confirmation to dive in again.
Law loses count of how many times he comes. At some point, he can’t get hard at all, no matter how his cock ruts against the pillows. Even as his nerves scream at the overstimulation, Law doesn’t think of saying stop because for once he feels safe, indulged and pleasured.
But he does beg. Begs for Luffy’s cock and knot. Luffy’s cum on him at some point and Law can smell the potent alpha musk marking him and it drives him further with need. Luffy finishes the night with only his fingers in Law, but Law is too fucked out to care.
“One more,” Luffy rasps into his ear, three fingers deep inside him. The sound of his fingers squelching out of Law’s soaked ass is deplorable as it is hot.
Law blinks through teary eyes. He doesn’t even bother to protest, just seeking a kiss for comfort as Luffy passes over his too sensitive prostate again. He tastes himself on Luffy’s tongue and the primal possessiveness is almost more effective in making him lose control that the overstimulation.
When he cums, he nearly passes out. He’s glad he doesn’t because the image of Luffy using his drenched hand to jack himself off is one of the single hottest things Law has ever seen. The look on Luffy’s face has Law using the last of his strength to cant his hips back, presenting his ass. Luffy cums all over it and Law shudders. The realization of just how messy and loose he is absurdly has Law feeling emotional.
Luffy is there, gathering him up. “- so good, so perfect, Torao, you’re mine, so good for me, Torao,” Law tunes back in to Luffy’s litany of praise, feeling warm from the inside out. He must have passed out because he is cleaner than he was.
Embarrassed, Law turns his head away, only realizing he had it pillowed on Luffy’s shoulder, right next to his neck.
“Torao? You feeling okay?”
Law winces as he tries to shift, giving up and laying limp. “Never been better,” he manages to rasp.
Luffy’s annoyingly proud laugh would have him attaching the Captain’s feet to his head on another day, but for now, Law basks in the comforting after glow. Luffy even feeds him, sharing his food and everything. It’s almost enough to make Law think he’s dreaming. But under that attentive care and exhaustion, it’s easy for Law to drift off for real.
“Tomorrow,” Law murmurs, tilting his head up as Luffy places lazy kisses over his face, “I’m going to play with you.”
Luffy freezes as Law grabs his ass in a tight hold. Then the Pirate King laughs. “Looking forward to it, Torao!”
