Of all the things Kidd thought he would overhear, it wasn't this.
He had followed Trafalgar and Strawhat when they snuck off explicitly because of how pissed off the Heart's captain looked. He wanted to jump in the middle of whatever fight Law was about to start just for the hell of it. After all, the party was getting boring.
He tries to find fluctuations in their haki, waiting to jump them both at the moment it would catch them the most off guard, but both of them are oddly calm. He can't even hear their words clearly, let alone the sound of fighting. He creeps closer, moving his metal arm around the corner until the mirror finish reflects them both clearly.
Trafalgar has Strawhat's heart in his hand, checking it over by delicately running his finger across the surface and doing who knows what with his devil fruit. Strawhat is watching intently, eyes wide and curious. "You scared the shit out of me." Trafalgar says it almost fondly, but the way his lips are pressed together indicate that it's true. "When your heart stopped."
Strawhat only laughs, but it's a much smaller quieter one than Kidd has ever heard from him, "Call it even for Dressrosa?"
Kidd doesn't even have time to blink before Trafalgar has him pinned to the wall of the ally, the hand placing his heart back inside with pinpoint accuracy, "You're infuriating. Both with this and all of the orders-"
"I've never given you an order," Strawhat is quick to interrupt. Rather than fight his way free, he leans his face against Trafalgar's shoulder, and Kidd has to strain to hear him instead of reading his lips. "Only suggestions."
"Suggestions, huh?" Trafalgar counters. The hand that's flat on Strawhat's chest trails upwards until it's buried in his hair, his hat getting knocked gently behind his head in the process.
Kidd's starting to think he greatly misjudged what would happen once those two were alone. This isn't two rival captains from the worst generation, but rather two people who care about one another. It feels odd to see all of this after watching them bicker so much.
Luffy leans into Law's hand. "Yep. Just like how nothing you tell me like this is really an order either." The hand in his hair visibly tightens and it rips a soft groan out of the younger captain. "Because I could get right out of this if I wanted to." He lifts his head just enough to be nose to nose with Law, a smirk tugging at his lips.
"Like I said, infuriating." Kidd doesn't think Law looks pissed anymore, not when he crashes his lips against Luffy's and grabs him wherever he seems to desire.
Kidd knows he should leave, but he can't help but be mesmerized by the way they move against one another. Law's deft fingers have Luffy's kimono falling off his shoulders in under a minute, hands sinking into soft flesh the moment it's exposed to the night air, whereas Luffy appears more concerned with keeping their lips attached. He bites at Law's lips with all the same fervor he uses to devour meals.
There's no use in denying how hot they are, not when his pants have become more suffocating than the collar he was forced into at Udon. Kidd allows himself a little leeway and busies his real hand by palming his clothed cock. If they're going to keep putting on a show in public then they can't complain if I continue to watch.
In the half second Kidd glances down at his belt to get it undone, Luffy has sunk his teeth into Law's shoulder, drawing out a low groan. "You're a fucking menace, Lu-ya."
Luffy pulls off his neck with a wet pop, "gonna stop me?" There's something wild behind his eyes that Kidd has only caught glimpses of before. Law shakes his head, and it's all the permission Luffy needs. He goes right back to marking Law's neck and shoulders.
Kidd has to bite back a gasp when Law lifts one of Luffy's leg's into an oversplit, leaving Luffy's cunt on full display and dripping enticingly. The blocky "E" and "A" tattooed on Law's hand quickly vanish completely inside Luffy without any resistance. Luffy's jaw snaps open, thin lines of saliva connecting back to Law's shoulder, and the moan that tears out of him shatters the last of Kidd's self control.
He frees his dick the rest of the way, getting caught be damned.
Unfortunately for him, Law chooses that moment to look right at his hiding spot. "Going to continue being a voyeur, Eustass-ya? Or are you going to join in?"
Luffy visibly clenches around Law's fingers, and Kidd caves to the whims of the wrong head.
Luffy visibly clenches around Law's fingers, and Kidd caves to the whims of the wrong head. He slips around the corner, unashamed. "I didn't think you were one to share, Trafalgar. Maybe you do have some manners in you."
"Our victory left me feeling generous." Law shrugs and holds eye contact with Kidd as the "T" joins the other two letters inside Luffy.
Luffy's forehead is pressed to Law's chest, eyelids fluttering, "I knew you were gonna let him watch, but I didn't think you'd invite him."
Law snorts. "May as well if he's going to pretend we couldn't sense his Haki as he poked at ours. You opposed?"
Luffy shakes his head before turning just enough to look at Kidd, "Fuck no." The other captain curses sparingly compared to Kidd's crew, but the breathy way it escaped him has Kidd desperate to hear him scream it instead. "I saw his dick a couple times in Udon. It's huge." Luffy licks his lips, his tongue stretching unnaturally as he eyes Kidd's cock like it's his next treat.
"Didn't think you were into sex, otherwise I might have fucked you against the bars of the cell." Kidd steps closer until he can see the fluid pooling in Law's palm, "With how much you seem to like being watched, I bet you'd have loved that." He strokes himself slowly, enjoying the way it draws Law's eyes as well.
"He would've, and he's a great fuck." Law slides his fingers out and shoves them into Luffy's mouth instead to keep him quiet. "His devil fruit makes sure of that." Luffy drops his raised leg back to the ground, looking far too content to be licking Law's hand clean.
"How so?" Kidd asks, as he fills in the now open space in front of Luffy. Law has pulled him off the wall just enough to get behind him.
The smug grin that overtakes Law gives him an air of confidence that Kidd hasn't seen outside of battle. "You haven't thought about it enough then." He wipes the saliva onto Luffy's kimono once the younger captain finally lets go. "Let him suck you off."
"Gladly." Kidd gives a cursory glance around and uses his own devil fruit to attract what little metal is nearby. It's just barely enough to create a shoddy little table, and Law gets the hint immediately and pushes Luffy across it. He shivers for a moment, but doesn't complain, only opening his mouth eagerly. "Should have known you'd have an oral fixation with how much you like to stuff your face."
"So?" Luffy looks up at Kidd through his eyelashes, lips puffy and kiss bruised, and he has to swallow the urge to slam inside. "I like to eat; I like to suck dick. It's just two different kinds of meat." He looks two seconds from laughing at his own joke before a sharp slap against his ass has him choking on a yelp. It only takes Kidd until the red handprint starts appearing to realize that Law used haki. "Torao—"
Law raises an eyebrow, "Be a good boy and do as you were told."
It's as if Law flipped a switch, and Kidd mentally notes that Luffy has a deep seated praise kink. Luffy grabs Kidd by his thighs, short yet sharp nails digging into the muscle as he yanks him forwards hungrily. In one smooth motion, Kidd's entire cock has been slid down his throat. "oh fuck. " Luffy's throat muscles constrict in a way that would make a sex toy jealous, and it forces Kidd to hold onto the table to keep upright. Rubber and silicone are similar enough. I bet he could take it.
"I told you." Law still looks far too smug, but Kidd doesn't care to argue with him when whatever he's doing is causing Luffy to moan around him, making up for the lack of gagging.
Kidd reaches down with his real hand and wraps it around Luffy's throat, groaning deeply as he squeezes. He can feel every time his dick slides passed his palm, but Luffy never seems to choke, even when tears start to form in his eyes. He looks blissed out of his mind, and once Kidd tears his gaze away and up to Law it's easy to see why.
Law is buried deep inside him, thrusting slowly, and rubbing his clit in slow circles. For the briefest of moments his nose scrunches in concentration. "You haven't thought enough about my devil fruit either." Law's rooms have a sort of fuzzy feeling to them, and before Kidd can ask, one of Law's organ cubes is in his hand. Kidd doesn't recognize what he's taken, but when Law squeezes it, his vision nearly whites out with pleasure.
Kidd hunches over, thrusting faster down Luffy's throat, and a hand in his hair tugs him forward. "You're almost cute when you finally stop talking, Eustass-ya." Law lips brush lightly against his until the moment they crash against him hungrily instead, reminding Kidd that Law too, is a D. Kidd is beginning to get light headed from both the lack of air and Law's insistence on using his prostate like a stress ball.
It doesn't take long for Kidd to fall over the edge, but Luffy won't let him pull out of his sinfully tight throat until Kidd's biting back pathetic noises he'll deny later. He burn's Luffy's impish grin into the back of his mind.
"Awwww you cum too fast, Gizao." The grin turns into a pout as he realizes he's lost his gag, but Law doesn't give him time to complain. He pulls Luffy against his chest, which draws out the neediest whine Kidd's ever had the blessing to hear.
"You're no better, Lu-ya." It's whispered right into the other captain's ear, but the low rumble of Law's voice travels when he wants it too. He smirks at Kidd from over Luffy's shoulder while shifting Luffy's rubbery body around with ease. The second Luffy is where Law wants him, Kidd gets a front row seat to the show.
Luffy's body can manage the rougher handling, and he seems to enjoy that fact immensely, begging for Law to give him more through cracking moans and gasps. He starts to get louder and louder, not that Luffy has ever been a quiet person, so Law beckons Kidd closer.
It's easy enough to get the hint.
Kidd shoves his fingers into Luffy's mouth, forcing his volume to lessen while he sucks. It doesn't take long after that for his body to begin shaking in Law's hold. His eyes roll back into his head, and for the first time that night, he chokes just enough to be audible while he cums. Kidd removes his fingers, spit dripping down Luffy's chin, but his focus isn't on that. It's on the river of squirt running down all three of their legs.
Luffy's cheeky grin is back in place as soon as he catches his breath. "Wanna keep going?"
