Katsuki's sick of being sheltered all the time, sick of being told he can't do that or he can't go there. He hates the high society he's forced to interact with every goddamn day thanks to being the governor's son.
So today he decides to sneak out in the evening, dressed as a commoner. He goes to one of the taverns by the docks. It's loud, smelly, and occasionally sticky but it feels alive and he loves it. People don't feel fake, don't filter their words, it's basically perfect in his eyes.
Some drunkard bumps into him and tells him to "fucking watch it" before shoving him roughly. And for once in his life Katsuki can just start a fight like he's wanted to so many times before. So he decks the man straight in the jaw. It feels amazing!
The man's friends come to collect him, rounding on Katsuki. It's one against six and half of them are fucking huge, but Katsuki hasn't spent years training for nothing. He could probably take them. He's about to find out anyway. He grins and cracks his knuckles.
His opponents seem nervous all of a sudden but it takes him a moment to realize they're not looking at him but rather - behind him. Before he can turn, he feels a heavy arm draping across his shoulders. He looks up and the first thing he notices is that there's a lot of red. Long wild red hair tied back by a black bandana. Small braids are visible here and there, each ending with a shiny jewel. Katsuki takes a good look at the redhead's outfit.
He's not stupid. He can recognize a pirate when he sees one. And he's always wanted to meet a pirate. The drunkard's friends scatter quickly. The redhead didn't even have to utter a word so Katsuki deduces that he must have a reputation.
The man introduces himself as Eijirou and invites Katsuki to his table where his rowdy friends are drinking and singing. They do look like the most interesting group in the tavern by a long shot so Katsuki agrees. Eijirou pulls him beside him on the bench. A few minutes are all it takes for Katsuki to realize Eijirou's the captain of the crew. And a few more to realize he's really into him.
Flirting in high society is strict and boring and has never been to Katsuki's liking even one bit. Lots of flowery fake words. No passion whatsoever.
This? This is different. Eijirou's hand is heavy on Katsuki's inner thigh, his breath is hot against Katsuki's neck, and his words would definitely be considered filthy back home. Katsuki's never felt the center of attention like that before. But he loves it. So when he feels lips against his, he presses back, opens up, and welcomes a warm tongue in his mouth.
The kiss is sloppy with desire and tastes of rum. Katsuki can't imagine a better first. He hears cheers and snickers around him but he pays them no mind. Not even when Eijirou stands up, pulls Katsuki up, and bids his crew good night with a grin and the noise intensifies.
The night has properly fallen now and the chill outside bites at Katsuki's skin, except for where he's flush against Eijirou. Eijirou leads him to a ship on the far side of the docks. Katsuki hoped to see a pirate flag but it's been taken down. Maybe he'll get to see it in the morning because now he's ushered directly to the captain's cabin.
The door has barely shut behind him when he's pressed against it, Eijirou's hands firm on his waist. The kiss is more urgent now. Earlier has clearly been a toned down preview. Katsuki raises his hands to the back of Eijirou's head and grips the hair, probably with more force than he should. But the appreciative growl against his lips tells him otherwise so he pulls again.
Eijirou draws back and grins at him before turning his attention to his neck, sucking just under Katsuki's ear and trailing kisses down the neck while his hands work Katsuki's pants open. There's the sound fabric tearing and the next moment the pants and underwear pool around Katsuki's feet.
Eijirou takes a moment to get his own shirt off and Katsuki seizes this opportunity to kick his boots and pants off. His own shirt still covers his privates but as soon as Eijirou's done undressing, he's pulling it up to Katsuki's chin, exposing his cock and one rosy nipple.
Katsuki's not used to being that exposed and can't help squirming a bit. But his cock stands even prouder, loving how Eijirou's eyes trail down his naked body, how Eijirou's free hand feels hot against his stomach as it inches down. His heart is beating fast and loud in his chest when fingers comb through his blond pubes and curl around his cock. He bites his lower lip when a thumb presses against the sensitive head of his cock and rubs the precum there.
He's been holding his moans rather well so far, but that thin damn breaks when Eijirou puts his lips around his exposed nipple, altering between sucking and licking it. And Katsuki's far from being used to touch. Shaking hands is the most action he's been getting for a long time. And nobody has touched him like this before. It's all a bit too much and too intense.
Eijirou is working his hand on Katsuki’s cock faster and faster, every now and then teasing the head. Katsuki knows he's close but before he has a chance to say so, Eijirou bites his nipple and Katsuki comes with a strangled moan against the pirate's chest. He's given just enough time to ride the last wave of his orgasm before he's carried to bed and manhandled face down and ass up on the mattress. A straw pokes him in the cheek through the bed sheet but he couldn't care less.
He spreads his legs wide and curves his spine enough so his chest is flat against the mattress. Flexibility has never been a problem for him. The appreciative hum he hears from behind goes straight to his ego. Eijirou's hands are warm on his ass, pulling and pushing his cheeks apart. Katsuki can tell his hole is twitching on its own.
The pad of a thumb presses against it just enough to tease him before retreating. Katsuki swears loudly into the mattress and turns his head to the best of his ability only to see Eijirou collecting Katsuki's cum from where it has run down his chest. Then the finger is back against Katsuki's hole, wet and probing. Katsuki rests his cheek against the mattress again. Eijirou goes slowly, definitely having caught on to Katsuki's inexperience.
It's not that Katsuki hasn't messed around with his hole before. He has, more times than he can remember. But the pirate's so quick to find his sweet spot it makes Katsuki's own struggles his first time look laughable in comparison.
Every press of Eijirou's fingers against his prostrate pulls a loud moan out of him. And it's apparent that Eijirou loves those sounds because he keeps massaging the spot until Katsuki cums again, this time painting the bed sheet.
Katsuki's words slur when he finally speaks, "Fucking- fuck me already." The rustle of fabric behind him tells Katsuki that his "order" is being carried on. He may have been stretched a lot but Eijirou's cock still gives him a bit of a burn. He loves it.
Whatever patience Eijirou has managed up until now snaps when Katsuki pushes his ass back and takes the rest of his cock in. Eijirou's grip on Katsuki's hips is bruising and only the first thrust has any restraint to it.
Katsuki cums twice more that night. He's never felt more boneless in his life.
The morning comes way too quickly. Katsuki's woken up by a commotion on deck. But he doesn't want to get up. He's comfortable against Eijirou's warm chest and the weight of the pirate's arm around his waist feels so right. The rocking of the ship makes his eyelids heavy again. And then one of the crew mates bursts in and the peaceful moment is gone. Eijirou rises behind Katsuki, asking what the fuck is going on.
"The governor's son's gone missing apparently. They think someone kidnapped the brat so they're searching the whole town. We need to leave port now," the crew mate ends his explanation with a pointed look towards Katsuki.
And for a split second Katsuki thinks they know. But then Eijirou speaks and it becomes apparent they have no idea whatsoever.
"Who's crazy enough to mess with governor Mitsuki? Even I don't want to cross her."
Katsuki almost laughs out loud.
The arm around his waist retreats and he immediately misses it. He shouldn't have grown so attached to this pirate and yet... But he doesn't even know him. They've barely spoken. And yet...
"Sorry, treasure," Eijirou speaks, "I was hoping for another round in the morning but it seems me and my crew need to leave."
Katsuki's never felt so torn. He had fully intended on getting home by the morning. That was the plan. He wanted one night out to feel alive. But to leave his home so suddenly with no explanation? And with pirates? Those people are strangers. Eijirou is a stranger. And yet he feels such a pull towards him, towards this life where he doesn't have to pretend he's someone he's not.
"So you should go. Unless you want to stay with us," Eijirou adds, teasingly and almost jokingly. But if he doesn't mean it, he wouldn't have said it, right? It's what Katsuki thinks. So he'll take the pirate up on his offer.
It's definitely a thoughtless decision and he may regret it later but fuck it. He doesn't want to go back home. He'll... he'll miss his parents, sure. But he still doesn't want to go back. He wants to feel free. And this crew is a golden ticket to freedom. So he's staying.
He'll let his mother know he's alright. Somehow. Preferably soon. He'll figure it out. But for now-
"Alright then, I'm staying," he says with finality and sees Eijirou's eyes widening at his decision.
"You really sure?" Eijirou asks after a few seconds.
"Yes."
"Do you know your way around a ship? You'll have to help the crew, you know."
Katsuki rolls his eyes.
"I don't but I'm not a freeloader so I'll learn. I'm a quick study as you found out last night," he says cheekily and is rewarded with a toothy grin from the pirate.
"Is that what it was? I thought you were just a natural."
They set sail and Katsuki watches as the port and town become smaller and smaller in the distance. He feels tightness in his chest as his life changes. But he doesn't regret it. He tugs at Eijirou’s shirt until the pirate lowers his head to him so he could whisper in his ear.
"I'm Governor Mitsuki's son."
Maybe he shouldn't have told him. Not yet. Or better - he should've spilled the beans while they were still at the port so if this whole situation goes sideways, he could've had an escape route. But today's a day for questionable decisions it seems.
"Haha, a good joke!" Eijirou laughs at first, not believing him.
And maybe Katsuki should leave it at that. Maybe it's for the best. He should laugh as well and play it off as a joke. But his gut tells him it'll be alright. And he's curious about Eijirou's reaction. So he doesn't laugh and gets to watch the realization dawning on Eijirou's face in real time. He has never seen a man pale quite so quickly.
"We have to get you back!"
Katsuki blinks at Eijirou's words. What-
"The fuck?! I'm not going back!"
"Katsuki, your mother will have me hanged-"
"No!"
Eijirou's determination to get the ship around and dump Katsuki back at port seems to subside at Katsuki's vehement rejection of that idea. He runs his hands down his face and sighs.
"You're gonna be the death of me, treasure." Katsuki rolls his eyes at him.
"Don't be so dramatic. My mother doesn't even know I'm here. I didn't tell anyone where I was going so you're fucking fine, relax. I thought you may have tried to get me ransomed, you know. Not to get me back."
Eijirou laughs.
"Only a fool would try that. If I knew who you were last night, I would've stayed away from you. But...," he strokes Katsuki's cheek, "I guess I'm in too deep now."
'You were in deep alright,' Katsuki mind supplies. He leans into the touch and grins.
"You going to show me your ship, Captain?"
"Aye!"
