Chapter Text
What happened?
Everything was a blur.
Luffy was arguing and fighting with Gizao as usual in their shared cell. Nothing new, the guards and prisoners had gotten used to their banter for the past few days. It was late at night, he either provoked the brute or it was the other way around, either way… it lead to this.
They were kissing.
The front of Kid’s body pressed against his chest while Luffy’s back was on the wall, effectively trapping him. Luffy would have fought back, he had the strength to lift huge boulders without his devil-fruit powers, after all. But Kid was the same as him, their physical strength was evenly matched even with only one arm. So by some crazy skill, Kid had somehow opened his yukata, exposing himself, while both Luffy's wrists were held tight by Kid's one and only hand. Luffy would have kicked him, but the brute knew what he was doing when he pushed Luffy to the wall. He made them sit on the ground and had Luffy's legs wrapped around his torso. The younger pirate would have done something about it if Kid hadn't taken all the space between them, he couldn't even move.
The kiss between them had to stop. He was going insane with the lack of air and the tongue that was being forced down his throat, at least that's how he felt. Right when he thought about biting it, Kid pulled away to catch a deep breath.
"Not bad," Kid chuckled, letting go of Luffy's wrists. They were definitely bruised.
Luffy blushed, covering his face with his hand. "I hate you."
"Was that your first kiss?" The nerve of the guy, Luffy gritted his teeth. "Is that why you're sulking?"
"We were fighting not too long ago! How did it lead to this? And why did you undo my yukata!" He immediately tried to cover himself with his hands. Kid stopped him, then leaned his face to his neck.
"Don't," He growled on his skin. "Let me see more of you," and then he bit him on the shoulder.
"AH-MMMHH!" His scream was muffled by the large hand.
"Shh, are you trying to wake up the whole prison!?"
"How do you know they're asleep? Our fight from earlier wasn't exactly quite either!"
"So you'd rather be screaming your lungs out for everyone to hear what I'm going to do with you?" Kid smirked at the lack of response, it was embarrassing to answer back. "That's what I thought. Now be good and let me have my way with you. "
"Gizao…" Luffy whimpered when the older bit one spot after another on his neck more harshly. "Gizao... mhh, wait, Gizao..."
"Jeez, shut it. Don't whine. It's your fault for being so addictive."
What the hell is that supposed to mean?
Kid's large hand was touching every inch and curve of Luffy's body while his lips kissed and marked him. Since he only had one arm, Luffy could feel just how thoroughly his fingers touched the surface of his skin. Despite how rough Kid was with his teeth on Luffy's mouth and neck, the rest of his body was treated more delicately. The fact that Kid was doing something like this made Luffy nervous, it didn't fit his character in the slightest.
"Ah!" The younger gasped at the sensation of being groped from behind. The sound from his mouth surprised both of them, Luffy turned red and looked away from Kid's smirk. What was that?
"Wanna sing again for me, pretty boy?" Luffy glared at him as he covered his mouth with one hand while the other harshly gripped Kid's muscled shoulder. Jerk. "Mmmh!" Luffy's muffled noise amused Kid when he groped the same place again.
Kid licked his lips. "... Shit, I thought harassing you would be enough. I want more…" He pushed Luffy down suddenly to the cell floor before Luffy could react. "I want you right now. "
"... What?" That shocked him.
"I…" Kid swore, "Why is this so hard?" He groaned before kissing Luffy. The kiss quickly became heated and their tongues clashed for dominance, obviously, Kid won. "Be mine…. For tonight…" he said between their kisses.
Luffy pulled away when he looked to the side for air. "Yours…?"
"Yeah… only tonight… or… until we both can get out of here. That arrangement is fine with you, right?"
Was he fine with this? He had no clue... but he wasn't exactly against it either. "Yeah…I guess… I.. still want to be the Pirate King."
The red-haired pirate chuckled. "Yeah, I figured." He kissed Luffy again, this time more tenderly. Their lips gently touched each other's, Kid nibbled his bottom lip, trying to deepen the kiss once more but without impatience. Luffy's hand carded through his red hair while the arm hung around his thick neck. The feeling was surreal. He never expected Kid could be capable of treating him so kindly.
They both pulled away for air and stared at each other for a few heartbeats.
"...You seem too innocent… Forget the kiss, I thought Trafalgar already made a move with you." Kid had their foreheads touched as he closed his eyes.
Huh? Why did he bring Law all of a sudden… he ruined the mood.
"... Torao and I made an alliance. That's all. He's nakama. He's not into me like that."
"You don't know… I can't believe this… "he murmured. He lifted his forehead, and Luffy felt his lips pressing his neck again. "Oh well, too bad. I'm going to mark you up so bad, your rubber body won't ever heal."
"My rubber body isn't active now with the sea prism stone on me!"
"Good. That'll make my marks on you last longer."
" Nooo, don't. I'm going to take down Kaido! I don't wanna be in an embarrassing state when I fight him–ah!" Luffy squeaked when Kid bit the shell of his ear.
"Dumbass, don't mention another man's name when I'm about to have sex with you," he growled in his ear, making Luffy shiver from the hotness of his breath " It ruins the mood. And I'm going to take down Kaido! "
"That's my line! " Luffy growled back, annoyed by the change in treatment. "You brought up Torao out of nowhere! And I'll be the one to kick Kaido's ass!"
"Tch! Quit arguing with me right now! I wanna mess you up real good and sleep before we get forced to work in the morning, so let's start already and give yourself to me. "
He wanted to argue, but Luffy went red from Kid's choice of words.
That night udon prison was noisy until dawn.
Kid woke up extremely refreshed. It has been a while after all. Man, sex with the straw hat monkey was more satisfying than he thought. His cries for it to stop, yet contradictory when he begs for more. He noted mentally that kissing him seemed to make Luffy feel more relaxed while they were at it, making the experience more pleasurable for both of them.
The said monkey was glaring at him from the corner of his eyes. How long was he awake? Kid chuckled, not that it mattered.
"You look happy," he deadpanned, his naked body pressed against his. Kid's furry coat was big enough to cover both of them when they slept soundly last night. "I hate you. You broke my back. I can't feel anything from down there while the rest of my body feels sore."
"Your fault for being a virgin."
Luffy's mood soured even more. "I hope you drown in the sea somewhere. You… you definitely enjoyed toying with me more than needed... Gizao is a pervert…"
"Oh? Then who's the stupid monkey who begged–"
"Ahhh, I don't wanna hear!!!" Luffy pulled Kid's furry coat above his head to hide himself. "It's all your fault! What happens if I like too much of the kind of stuff you did to me?"
"Then we'll hook up again.” He nonchalantly said, “If you try to pretend you don't like it, I'll search for your ship in the sea and find you, then I'll drag you to my ship and make you love it more in my bedroom. "
"You're impossible!"
"As I said, you're addicting. You're mine now. remember that. "
Luffy pulled the furry coat off his face to look at him. "... Didn't you say this arrangement will stay valid until we escape from here?"
A beat. "… Yeah, about that… I was starting to have second thoughts around our 5th or 6th round–"
"Gizao! "
"What? We both felt good right? Damn, my sex drive wasn't even like this with women. Something about you makes me want to mess you up more. ”
"So–what? I'm going to be your property and live with your crew on your ship just for sex?"
"Not a bad idea– “
"Gizao!"”
“--but I'm not that kind of man… we're both pirates competing for the One Piece and I'm not going to lose a rival using that method. That’s too low, even for me.”
Luffy was silent as he made a face like he was thinking hard. Can't blame him. It was supposed to be a one-night stand, but it's becoming more than that. "Gizao, I'm confused. Are we… what are we then?"
Kid didn’t respond. Guess he wasn’t sure, either. The older sat up and patted his knees. "... Come here on my lap…"
It seemed like an outrageous demand given the incredulous reaction he got from the other. "Eh? But I can't move,"
"God damned it." He lifted Luffy by the arm and maneuvered him to sit on his lap effortlessly. He kissed Luffy immediately, and the other complied with the kiss. "Ha…" He took a breath when they pulled away. "I honestly don't know what we are. I'd like to say I want to be your boyfriend, but I know damn well I'm not boyfriend material. Here at sea, pirates can't exactly date. But despite that fact, I know I want to have you for myself."
Luffy stared at him in shock. Kid wants him? The confession made his gut feel warm. His face heated. The navy wanted him because he was a criminal, other than that, no one really expressed their desire for him. Was this supposed to be a romantic gesture?
"Your face is going red." He pointed the obvious, " Is this the first time being confessed to?"
"Shut-shut up…." He turned his face away. "Things are going too fast-I-I can't wrap my head around it.."
How cute. Kid wanted to see more. He was contemplating whether they should go at it again, it's not like sex would kill this guy, but the plan was completely shattered when the guards opened their cell and started barking orders.
He'll kill them. He's going to kill them for ruining his fun.
Luffy's body said no to getting up and he remained behind the cell to rest, so Kid did twice the amount of hauling and work to cover his lover's labor (if he can call Luffy that). The guards, on that part, didn't argue with him. Kid's intimidating figure and the use of his Haki made them agree to his demands. The Dangos they shared when Kid returned were enough to sate their hunger, especially Luffy's. The boy could eat a horse.
"Are you crazy?" Luffy whispered incredulously when his clothing was stripped from him. "Are you trying to stop me from ever walking again?"
"Tell me who's the gentleman who covered your side of your labor and brought his share of Dangos for you?"
"It's your fault I couldn't move to begin with! Stupid Gizao, we went all night last night! "
"I thought we both were captains with plenty of stamina. " Kid hovered over him.
Luffy tried resisting as he pushed his hands on his chest to prevent him from coming any closer. "Well… yeah, that's usually the case… but you went completely overboard! It… was my first time… too. You… you didn't hold back at all! "
“Sorry... The idea that you would be seeing Trafalgar again due to your alliance drove me crazy. So I took the time and rounds making lots of marks on your body.”
“Why is Torao brought into this conversation again!? Seriously, are you jealous or something? I told you, he’s just my nakama! There’s nothing going on between us.”
He rolled his eyes, giving up completely. It’s not his damn job to make this naive monkey understand what’s going on. Kid wasn’t certain how Law felt about Luffy, but his eyes didn’t deceive him when he saw the surgeon looking at Luffy like fine meat when the younger made his dramatic entrance at the auction house 2 years ago.
Kid pinched Luffy's belly out of annoyance, and the other jolted from the sudden sensation.
Anyways, regardless of how Law felt, that man should have made a move first. Because Kid wasn’t going to let the prey he caught go into another man’s bedroom. Luffy was marked by Kid. He belonged to Kid, and Kid alone.
"Ah! Stop! Don't bite me! I told you, I don't want to look like a mess when I take down Kaido!"
"Would you not say another man's name and ruin the mood!? It makes this less hot!"
"Kaido! Kaido! Kaido! Torao! Torao! Torao!"
"That's it! I'm going to make sure you won't walk for the whole damn week !"
"Wait, no-Gizao! I'm sorry! Stop! Please don't-GizzAAAAOOO!"
