A/N: Hello everyone! I'd have never thought that one day I'd start writing my own fanfiction… I'm really happy I do now, though :D

This is a Law x Luffy story. You should be comfortable with the thought of both of them ending up together in this story. I got the idea for this watching the movie Hangover, by the way :) Sorry if the plot is a little cliché, but I've always wanted to write this ;)

Well, I am not someone who is that good with big words, so let's just start!

Chapter 1: A not so lucky bastard

Law woke up when he felt warm sunrays touching his face, illuminating his surroundings.

He smiled to himself, eyes still closed contently, when he noticed that he didn't even suffer from a trace of a hangover. Actually, his body felt strangely satisfied.

Damn, he sure was one lucky bastard. No matter how much he drank, Law never felt sick after a night of lots of booze.

Usually, Law was not someone who would mindlessly drink himself into oblivion. Being a doctor made him self-aware of his body and the dangers of massive amounts of alcohol.

Come to think of it, he was actually a little surprised with himself. Of course he loved drinking a cold beer after work, just like any other man, but he didn't remember what exactly made him go beyond his limits like that. Heck, he didn't even remember who or what convinced him to join his friends Shachi and Penguin to this stupid party at some ridiculous club he had never heard of before. He recalled someone claiming it was "the best party ever" and that he "had to join them". Was the party really that great? What was it even about?

God damnit, he didn't remember shit.

Suddenly, he felt something moving next to him on the bed, followed by a sleepy sigh.

Opening his eyes lazily and turning his head to the right, Law was faced with the image of a young man, definitely not older than 20 years, who was currently curled up to his side, his head resting on a pillow while his hand was right on top of Law's chest.

Law's naked chest.

However, this didn't shock Law at all. This was definitely not the first time he was faced with such a situation. He'd had his fair share of one night stands in the past and he surely didn't mind another name on his list. He propped himself up on his elbows a little bit, taking his time to examine his last night's lay. From the way his body was curled up against him, Law could tell that the boy was definitely shorter than himself. His dark hair was ruffled, his lithe and tanned body naked, his eyes tightly closed, his mouth slightly open and, oh god, were those hickeys on his neck? Everything about this boy basically screamed 'sex'.

God, Law definitely was one lucky bastard. Even when he was completely wasted he had managed to get himself a handsome partner to spend the night with.

A wave of pride shot through Law's body. He immediately liked this guy. Maybe when he woke up Law could convince him to go for a second round? What a pity he didn't remember last night, because from the way his body felt this guy must had been one hell of an animal in bed.

Law decided to close his eyes again and to just enjoy the moment.

He didn't recognize the room he was currently in, so he guessed he was at this boy's house. He was definitely a neat freak, considering the way the room was decorated. It was really bright, the white colors of the walls and of the bed actually made Law feel like he was in heaven right now. The way the sun shone through the windows was perfect, it made everything so much better.

And he surely didn't mind the warm body that was pressed against his side.

Law didn't regret his decision of joining his stupid friends at all now. It had been a long time since he had felt this cozy.

A content sigh left Law's mouth. He decided to continue sleeping until the boy next to him woke up. He would probably tell Law about how he made him go crazy last night, demand a second round, then they would share a nice breakfast together and Law would go home again.

Law felt some strands of his hair tickling his nose and moved his right hand to move them away. The moment his hand touched his face he noticed something. Something was off.

Something was definitely off.

He touched his face with his right hand again, telling himself in his head that it was just his imagination. But no, there it was again - The feeling of something that shouldn't be there. Something about his finger.

Law still had his hand right in front of his face when he opened his eyes slowly. Cold, grey eyes met a bright, golden ring.

Right on his fucking ring finger.

"What the fuck?!" Law didn't even try to be quiet as his upper body shot up into a sitting position within one second. His body was trembling slightly as he looked at his right hand, eyes wide open with shock. Fuck. This couldn't be true... This had to be some kind of twisted joke!

What the fuck happened last night?

"Hey you, wake up!" Law forcefully grabbed the boy next to him by his shoulders and started shaking him violently.

This guy better had an explanation for this bullshit. Did he trick him into all of this? God, what a desperate move. Law mentally smacked himself for falling for such a trick.

"Wh-what...? Hey!" the boy stuttered, obviously annoyed by the rude way he was woken up, and quickly tried to shove Law away.

Once Law let him go, still panting heavily, he felt the other's gaze on him. Law expected that guy to explain everything to him instantly.

Instead, the young boy just looked at him, crossed his arms in front of his chest, tilted his head to the side a little bit and blinked his eyes several times at him.

"Who are you?" he asked, looking puzzled.

Just great. This boy obviously didn't remember anything either. For the first time in his life, Law didn't know what to do. He had no memory of last night and was now stuck in one room with a stranger who seemed to be completely clueless as well.

Law started massaging his temples with his fingers, trying to think. There HAD to be something he should remember, but his memory was completely blank.

"My name is Luffy, by the way. Is this your place? Looks nice." the boy said as he eyed his surroundings.

"Look, I don't give a fuck about your name right n-", suddenly, Luffy's last words hit him like a truck. Law looked at the younger boy again, completely perplexed. "This...This is not your place?" he asked.

If this was not his own place and not this boy's, Luffy's, place...Then where the hell were they?

Luffy blinked his eyes cluelessly "Never been here before."

This was too absurd. Law silently prayed that this was just a dream. He looked at the nightstand next to his bed and noticed a telephone, a vase and a little card on top of it. He moved his hand towards the small table, curious about the card, grabbed it and read what was on it.

'Dressrosa Hotel, Honeymoon Suite'

His hands were shaking. Dressrosa didn't sound unfamiliar to him, it was a relatively big and well-known city after all. What bothered Law the most was the fact that it usually took at least 3 hours to drive there by car.

Law read the words over and over again, his grey eyes wide. He couldn't believe it. He didn't want to believe it. This had to be some kind of nightmare, he just wanted to wake up!

"Hey, what's up? Why are you shaking? Are you cold?" Luffy asked as he moved closer to Law. Law rubbed his face in desperation. This Luffy was obviously an idiot. How could he be so carefree? Maybe he should tell him what he'd found out so far.

He looked at Luffy's right hand and noticed the same ring Law was wearing on his ring finger. Law let out a sigh as he turned his serious gaze to Luffy's face.

"Luffy, look. Promise me to not freak out. It doesn't have to mean anything and we'll deal with it eventually. Take a look at your right hand, there's a-"

"HOLY FUCKING SHIT!" Luffy screamed as he moved his hand in front of his face and noticed the ring immediately. "D-Did you trick me into this?! Fuck you! Who the hell are you anyways?!" Luffy, fueled by panic, swiftly moved out of the bed, only to fall back on it clumsily when he winced at the pain that crept up his spine.

"Ouch...W-Why does my back hurt like that?" he muffled as he tried to massage his backside.

Despite the situation, Law couldn't hide his smirk at the innocent question.

"My name is Law. Seems like you're finally aware of the mess we're in."

Law moved to the side and got out of the bed. He picked up his clothes that were dumped all over the floor. Among his own stuff he found a blue vest and a pair of short jeans which obviously belonged to Luffy. He threw them towards the boy who was still sitting on the bed with a shocked and confused expression on his face as he continued massaging his own back.

"Law...D-Did we...Have...you know..." Luffy couldn't help stuttering and started fidgeting nervously. Law actually felt a little sorry for the boy, he obviously wasn't as used to these situations as Law.

"Have sex? Seems like it." Law said bluntly.

There was no reason for him to sugarcoat the facts after all. Seriously, it was not his job to comfort this boy.

Still sitting on the edge of the mattress, Luffy started putting on the clothes Law had thrown on the bed for him. Once he was fully dressed, he tried standing up carefully again.

Law couldn't help but chuckle at this. It made him feel strangely satisfied that he was the one to blame for the boy's limping. Once he stood on steady feet, Luffy pressed his fingers on his forehead and closed his eyes tightly.

"My head feels like shit…" he groaned "And my body doesn't feel any better either. You may be hot but you sure are not the gentle type in bed."

Law tried to hold back his laughter. No, he was everything but gentle in bed. But who could blame him? Law was not someone who would force his own ways on other people. Those who complained about the ache in the morning usually demanded him being rough the night before. Law only complied with what they wanted from him and this Luffy didn't seem to be an exception.

Completely lost in his own thoughts, Law didn't even notice when the young man bent down next to the bed and picked something off of the floor. He made his way over to Law and happily showed him what he had found.

"Hey look at this!" he exclaimed loudly as he waved a used condom right in front of Law's face. "This is relieving, at least we used protection!"

Law felt like puking. "Stop shoving it into my face! Throw it in the trash."

God, he was already annoyed. Sure, this boy had an attractive body and honestly, he was just Law's type, but his carefree and somewhat stupid behavior gave Law a hard time. He was not good at handling this kind of people.

A loud knock on the door interrupted his thoughts.

Luffy, not much to Law's surprise, didn't even think for one second as he curiously walked towards the door. Law, fortunately, managed to grab Luffy's arm just in time before the idiot managed to open the door and yanked him back roughly. "What the fuck do you think you're doing?" Law snarled angrily at Luffy.

"Opening the door?" Luffy growled back, sounding equally annoyed. He obviously didn't like being told what not to do.

"Do me a damn favor and think before you act! Do you want them catching us in this situation? Fuck, we don't even know who's knocking outside!" Law tried to keep his voice down, not wanting the person who was currently in front of the door hearing him.

He still managed to sound beyond pissed though.

The knocking started again and this time a male voice shouted "Room service! I'm delivering the food!"

"Food?!" Luffy exclaimed loudly before Law even had the chance of slapping his hand in front of the shorter boy's mouth to shut him up.

"I'll take care of it. You go and hide in the corner over there." Law pointed across the room, making clear that he did not want the man outside to see Luffy like that.

He was aware that they were currently in deep shit and the less people knew about it the better.

Luffy groaned again but didn't disobey Law.

"Don't even think about sending the food away." he mumbled as he walked towards the corner lazily with his hands behind his head.

Opening the door, Law first noticed a blond man who was wearing a neat looking black suit and a name plate reading 'Sanji'.

"I'm delivering the pre-ordered breakfast." the man explained politely as he moved back, giving Law the chance to see the carts of metal platters behind him. Law could have sworn that his eyes grew twice their size at the sight of the huge amount of food.

"I don't remember having ordered this." Law said.

Well, at least it was the truth. He really didn't remember. Besides, why would he order this much food?

He tried not to shudder as the smell of freshly baked bread hit his nose. Disgusting.

"Well maybe you didn't, but, " the man, Sanji, took a piece of paper from one of the carts. "It says that a certain Mr. Trafalgar ordered it last night."

Before Law could protest, the man continued, "First name's Luffy."

Fuck. This couldn't be true. This was way too fucked up to be true. Law didn't even know how to respond to this. And he usually was a man who always found witty words to say.

Not being able to find any words though, Law just nodded, still looking extremely shocked. He secretly hoped that the man didn't notice his weird behavior.

Law took hold of the carts and slammed the door shut in Sanji's face. Once the door was shut, Luffy ran towards the cart, not even minding the pain in his backside anymore. He excitedly grabbed the handles of the carts and moved them towards the bed. Law, not knowing what to do, just stood there in the middle of the room as he watched the boy who was sitting on the bed again devouring the food.

How the fuck did he get into this situation?

"Ne, Law," Luffy began talking, despite the fact that his mouth was filled with food and he was currently staining the bed sheet, "This ring is annoying."

"Yeah, I agree with that." Law walked up towards Luffy and sat down next to him on the bed. He eyed his own ring, hoping to get some kind of flashback, but it didn't work.

"Especially when you're trying to eat." Luffy stated as he grabbed a toast and spread a huge amount of jelly on it. Law only rolled his eyes at the stupid statement.

He pressed the thumb and the index finger of his left hand on the ring and applied some pressure, hoping to get the ring off as soon as possible. His brows furrowed when he didn't get it off at the first try. He repeated the action several times, but the ring stayed where it was.

"What the fuck is this?!" Law snarled angrily as he started to tug on the ring violently. He had no patience for these little games, he just wanted this piece of metal off!

"S-Shit, I can't get mine off either!" Luffy sounded frustrated as well as he copied Law's actions but failed miserably as well.

"It's too tight…" Law sighed and stopped trying to get the ring off. There was no point in it, he'd only hurt himself.

"Still, I don't wanna walk around with a fucking golden wedding ring on my hand." Law mumbled and glared at the ring, as if it was mocking him. Oh yes, he'd get this piece of shit off eventually, even if it meant to cut off his own finger.

They both sat on the bed in silence - Or well, not really. The sound of Luffy munching his food was still present, even though it seemed like he slowed down the speed of his chewing. About five minutes passed with neither of them saying a word.

"So," of course Luffy was the first one to break the silence as he turned to face Law "What are we gonna do now?"

Law closed his eyes for a second and searched his mind for a solution.

"Well…there is no way this whole shit is legit. We were both completely wasted, this can't be legal." He said, running a hand through his messy dark hair.

"Let's just…go to the city hall or somewhere… and try to fix this…" Law stood up again and moved towards his shoes that were placed right next to the door of their suite.

"Huh? Right now?" Luffy didn't look like he was expecting them to leave so soon already. He eyed the cart in front of him, there was still some food left. He didn't want to leave it behind.

"Yes, I do not intend to wait until our first anniversary." Law said sarcastically without looking at Luffy.

He was focused on tying his shoes right now. Of course he wanted to end this whole charade as soon as possible, there was no way he'd want to spend more time with this young idiot than necessary.

"You better get ready, too." Law looked at Luffy as he already moved to put on his jacket. It was then that Law noticed the somewhat worried expression on Luffy's face.

"Hey, what's wrong?" Law's voice sounded too concerned for his own liking "You can take some of the food with you, if that's what's bugging you right now."

"It's not that…I mean… Do you really think we can fix this?" Luffy showed him his hand with the ring, clarifying what he was referring to. The way Luffy looked at him gave Law a foreign feeling in his stomach, but he decided to ignore it for the moment.

"Yeah. Don't worry, ok? I'm sure we can fix it."

"What do you mean 'it can't be fixed'?"

Law shouted angrily at the short office worker in front of him as he slammed his fists down on the wooden surface of the desk. The man was scared to death, Law could tell. He looked like he wanted to hide himself under his desk, hoping to escape Law's rage.

"I-I-I said it c-can't be fixed that easily" the man tried to defend himself. His face was pale by now and Law even spotted some tears in the corners of his eyes.

"I told you everything about the situation. You just have to annul this marriage, it can't possibly be that difficult." The twenty six year old man said as he lifted his fists from the tiny office desk and folded his arms across his chest. His grey eyes seemed even colder as he glared daggers at the sweaty worker in front of him.

"M-Mr. Trafalgar, the rules are s-stricter here in Dressrosa, you see… Marriage is valued highly here, we cannot possible annul a marriage after just one day-" The man didn't even get the chance to continue explaining himself as Law roughly grabbed him by the throat and pulled him closer to himself. The look in his eyes told the poor man that Law was about to murder someone.

"I don't like repeating myself. I've already said that we were both completely drunk, ok? So don't tell me shit about valuing this." By now, Law was definitely ready to stab this guy. Or hit some kind of vital point. He was a doctor after all, he knew at least seven different ways of killing a person and making it look like an accident.

"I-I understand you, S-Sir, but in order to annul this marriage we n-need to wait at least one month-" the grip on the man's throat tightened "O-Okay, o-one week!"

The man stuttered, the lack of oxygen obvious. Law loosened his grip on his throat, but moved his hand in order to grab the man by his chin and force his head to turn into the direction of the window of the room instead. The force of Law's action made the man shut his eyes tightly.

"Can you see that boy sitting there?" Law's voice was dangerously low and calm, but the man knew that this was not a good sign at all.

He opened his eyes slowly and a saw a young man, probably still a teenager, sitting on a bench in front of the large building they were currently in. He looked happy as he stuffed himself full with potato chips.

Law told him that it was better for both of them that he dealt with this and suggested Luffy to wait outside for him. The younger man didn't disagree, he never liked dealing with paperwork or anything like that anyway, so he just waited outside for Law to finish.

The office worker nodded his head as he looked at Law again who was still glaring down at him.

"This boy" he started slowly "is annoyance on legs. If I have to spend one week married to him," Law moved his hand quickly to the man's throat again and tightened his grip immediately "I'm going to fucking lose my mind!"

The office worker was at a loss. He could fake the documents in order to get the marriage annulled faster, but if he got caught he'd definitely lose his job.

Well, better than dying, right?

"T-Three days!" the man practically screamed as he started seeing stars dancing in front of his eyes from his lack of air. Law reluctantly let go of the man but continued glaring at him like he was dirt under his shoes.

"It's the only thing I can do, Sir." He mumbled.

Law took a deep breath, trying to calm himself down. There was no way he would survive one month, or even one week, with that hyper teenager. Three days also sounded as if it would leave its stain on Law's nerves, but he guessed he would survive that. After all, it would mean that he only had to survive this weekend with the boy.

Without saying another word, Law just nodded and left the room. The man let himself slump into his chair when the dark haired man left, thanking God that he was still alive.

When Luffy saw Law leaving the building, he excitedly jumped off the bench and moved right up to Law. Unlike Law who was wearing a grumpy expression on his face, Luffy's wore a wide grin. They walked towards the hotel again.

"Law!" Law shut his eyes for a second when he heard the boy's loud and overly excited voice "How did it go? Everything's settled?" Luffy's grin never faded for a second.

"More or less. We'll have to stay here until Monday, though." Law didn't look at Luffy as he walked a few steps ahead of him. He was annoyed of the whole situation and the fact that Luffy didn't even seem to care for the seriousness of the situation they were in didn't help him either.

They decided to go and buy some basic spare clothes for the weekend and grabbed something to eat on their way. Law felt himself getting more and more pissed off with every minute that passed. Not only did the moron by his side lose his wallet the night before, so Law ended up paying for basically everything, but his constant chatter didn't even give Law the opportunity to collect his own thoughts. Law actually regretted the fact that he replied to the young man at some point and told him a little bit about himself. Luffy was just overly excited by everything Law said.

"Oh man Law, I can't believe you did that!" Luffy exclaimed happily and Law wished that he had just kept his mouth shut. "Did you really flip him off? And he really was your teacher? Damn, I didn't know you had this side in you!"

Law didn't reply. He didn't want to fall deeper into this shit. Whenever Law told the other man something about himself, Luffy would go on about it for what felt like eternity.

He couldn't wait for the weekend to be over.

It was already in the evening when they arrived at the hotel again. Surprisingly, Law was the first one to drop himself on the large bed of their suite. He covered his eyes with his arm as he felt a slight headache approaching.

"Law?" Luffy sounded curious as he lied down next to Law. Both were still wearing their shoes and jackets.

"Please, just don't get so close to me." Law mumbled, an annoyed tone visible in his voice. He just wanted to have some time for himself right now.

"Why not?" the nineteen year old asked playfully as he snuggled even closer to Law.

"God, how can you be so carefree?" Law asked. He honestly didn't know why Luffy was so goddamn happy about this.

"There's no need to worry, right?" Luffy said loudly and even punched lightly against Law's shoulder which only enhanced his annoyance. "You said that everything will be fine on Monday. Besides," Luffy placed his hand on Law's chest and moved closer to the older man's ear "this sounds like an adventure to me."

Law was obviously surprised of the boy's behavior right now, but he didn't dislike it. He opened his eyes slowly and looked at the boy who was so close to him, feeling the warmth of his skin. He didn't want to agree with Luffy, since Luffy was nothing more than an idiot to him, but he couldn't help himself from reacting to the boy's touch. And after all, he was right – It will be over on Monday and being stuck with an attractive young man in a hotel for one weekend wasn't something that happened every day. Yes, the situation did suck, but Law decided he could just as well make the best out of it. Besides, Luffy's words only seemed to fuel something deep within him. Law took his opportunity and leaned over Luffy as he moved his hands pinning him perfectly in place. For Luffy, it was like being trapped by some animal. He found himself not able to escape and not able to resist either.

Just then Law leaned down until his warm breath hit Luffy's ear "That was probably the only smart thing you've said so far."

Luffy felt his body getting warmer and could tell that Law was having the same effects on his own body. The atmosphere inside the hotel room was like a perfect mixture of excitement and sudden sexual tension. The body that was suddenly pressing against him was making every inch of his skin tingle in an exciting way.

"And I've got to admit, I totally feel like relieving some tension right now." Law's words were calm and collected, but the other's excitement was obvious to Luffy. It took lots of his will power not to shudder as he was laying underneath Law's body. "I am not someone to deny an obvious invitation, after all."

Law released Luffy's hands and moved his own to open Luffy's jacket slowly. Luffy took a deep breath. He saw Law's eyes fixed on the zipper of the jacket and couldn't help but feeling the arousal running through his body as he watched the older man. Tiny waves of shudder crept up his spine as Law slid his hand over the fabric of Luffy's shirt. The air around them had been changed into a shimmering hum of wild feelings.

Luffy couldn't stop his own body from reacting so violently to the handsome man pressed against him. Luffy was still a teenager after all, his hormones were completely out of control. He just wanted to drown in the delicious heat of Law's touches.

"I want it just as much as you." Luffy finally found his voice as well, and Law was genuinely surprised of the younger boy's words. But Luffy just wanted to tell Law that he was just as fine with this. There were too many hormones flowing through his blood all at once for him to think about something else right now. "When I saw you next to me this morning, I couldn't stop myself from wanting this."

"Guess we had the same thought then."

Luffy saw Law moving his face closer. He could feel the heat from his skin and the tickle of his breath on his lips. Law's mouth was no more than an inch away from his own. The only thing separating them both was the hot air of their own breaths. The mere thought of it made waves of electricity shoot up Luffy's spine. He almost moaned from the sensation alone.

"So you really are okay with this now? I don't usually like stopping once I started." Law looked down at Luffy, his eyes still filled with his own excitement.

Law moved his index finger softly and slowly to where Luffy's pulse was rapidly beating under the skin of his neck. It was a simple touch, but it was enough to make Luffy lose it.

He didn't want to hold back any longer. His whole frame was shivering from head to toe.

Law observed Luffy's reaction with amusement and shoved their hips roughly together. Luffy moaned at the sudden movement and threw his arms around Law's shoulders. Both of them were reacting so violently, it was like their instincts took completely over. A sudden wave of need rushed through them and left them both breathless.

They shoved their lips together before either of them even knew what they were doing.

The kiss was intoxicating for both of them. Luffy felt like drowning into this and knew that he wanted more. He moved his fingers excitedly, just wanting to grab on something, anything. His mind was completely clouded with the sensation of it, this passionate touch stole the breath from his lungs.

He felt Laws hands running down his chest, slowly slipping under the fabric and caressing the hot skin in a way that made him feel like he was going to lose it any second now. It was too much for his body, he could almost feel himself overloading.

And just when he knew he was surely going to lose it, Law pulled away.

The warmth of Law's body left him as he roughly pushed himself away from the younger man, letting himself fall down on the bed next to Luffy again. It felt cold, suddenly.

Law was breathing heavily as Luffy watched him touching his lips with his fingers.

"Fuck," Law panted heavily, his voice even deeper and rougher than usually. "That was a fucking good kiss." It was surprising for Luffy to see Law, who was normally collected and serious, to be at a loss.

Luffy didn't manage to reply. His mind was still clouded and he feared that his hunger for Law would not easily subdue after having gotten a taste of this.

Law was the first one to recover. His smirk appeared on his lips and he calmly adjusted his hair. "I didn't expect you to react like that. As exciting as this was, we will have to finish another time. I don't really feel like it's a good idea to just rush into something as heated as this after only one day."

Law really didn't feel like he needed to rush into this. He had Luffy just where he wanted him now.

Without another word, Law got up removed his jacket and shoes. He collected some of his spare clothes and disappeared into the bathroom.

Luffy stayed perfectly still, taking deep breaths as his heart was still beating rapidly. His body felt weak and he was not sure if he was ready to get up on his feet as well. He didn't know how much time passed until he finally got up and changed his clothes.

His mind was still slightly clouded and now he was sure that this weekend will be one of the most exciting ones of his life.
