Prompt: ZoSan, "too loud", requested by amaconn
Warning: implied sexual content
The whole operation had been set up carefully. The police had trailed the supposed diamond thieves for a while, until they knew for sure where their hideout was. According to an anonymous tip, the robbers would strike again tonight, which was why Zoro and Sanji on a stakeout, sitting in a hotel room that looked out on the thieves' hideout. The hideout had been bugged, so while Zoro sat in front of the window with binoculars, Sanji was fine-tuning the sound equipment until he could hear clearly what the thieves were saying.
"We're both in position," Zoro announced into a walkie-talkie to their partners, who were stationed somewhere else. "Clear view and sound." After he had gotten confirmation that his message was received, he placed the walkie-talkie next to him and focused on his mission.
From the bed, Sanji was watching him as he tried to make the sound more clearly. He didn't know why he got stuck with the Marimo of all people. Well, actually, he did know; it was because their colleagues found it absolutely hilarious to put them together on as many occasions as possible. Sanji and Zoro were both the best and the worst team ever. They never got along, but when they had a common goal, they would instantly work together. Hence their current situation.
He finally heard the voices of the thieves clearly, though they weren't talking about any kind of heist. Sighing, Sanji took a more comfortable position. This was going to be a long night.
Suddenly, a strange thumping sound came from the room next to theirs, as if something was repeatedly knocked against the wall, along with the sound of bedsprings.
Sanji took off his headphones. "What the hell is that?"
Zoro looked up, listening for a second before a smirk appeared on his face. "I think our neighbours are banging."
Sanji felt his cheeks flush. "What?"
"You know–"
"I know what banging is!" Sanji interrupted before he would get 'the talk' from Zoro of all people. "I'm just saying, do they have to be so loud?"
Zoro shrugged before turning back to his binoculars. "It's not like we're trying to sleep anyway."
"That's not the point! How am I supposed to hear anything?!"
"What, does it distract you?" Zoro asked teasingly. "Pervert."
"Who're you calling a pervert, moss head? And I just can't hear a thing because they're too loud!" Sanji snapped. "I'm gonna ask them to keep it down." He placed the headphones on Zoro's head. "Cover for me."
"Oi," Zoro started to protest, but Sanji was already at the door.
In the hallway, he walked over to the room where the sound was coming from and banged on the door. The creaking inside stopped, and Sanji thought he could hear some muffled voices inside. Then the door was opened by a freckled man with black hair wearing a robe. "May I help you?" he asked, sounding a little surprised at seeing Sanji.
Sanji cleared his throat. "Ah, well. You see, me and my partner have the room next to yours, and apparently, the walls are rather thin…" he trailed off, his cheeks flushed in embarrassment.
The man blinked for a moment, before he started laughing. "Oh, I'm sorry! Marco, do you hear that? I told you you shouldn't slam me into the headboard like that!" He opened the door a little further, and Sanji could see a blond man sitting on the bed, only covered by a sheet and looking absolutely mortified. "You see," the freckled man continued cheerfully, "it's been a while since we got together so we were both a little eager. We'll try to keep it down, though I can't make any promises." He waggled his eyebrows suggestively. "Marco's very thorough."
Sanji could only gape at the man. He hadn't expected the conversation to go like this. This man seemed to have absolutely no shame.
"Oi, Curly-brow! I need you in here!" Zoro's voice suddenly sounded, and if possible, the smirk on the man's face grew even more.
"Oh, I get it. You try to keep it down too." He winked before closing the door.
Sanji stared at the door for a moment, trying to scramble his thoughts together. That guy couldn't possibly think that he and Zoro…
"Curly!" it sounded impatiently from their room.
Sanji made his way back inside and closed the door with a bang. "Way to go, Marimo. Now our neighbours think we're about to…"
Zoro turned around from his position at the window. "About to do what?"
"You know… What they're doing," Sanji muttered, his ears bright red.
Zoro looked around and snorted. "Let them think what they want. You know, for a pervert, you're an awful prude when it comes to sex."
"Shut up, Moss-head! Some things are just supposed to be private." Sanji snatched his headphones back and sat down on his previous spot on the bed. His neighbour hadn't lied; Sanji couldn't hear anything coming from the other room anymore. Or perhaps he had just ruined the mood, though the freckled man had looked hardly shy about his activities. His partner on the other hand…
Sanji shook his head. He didn't want to think about that anymore. Still, he couldn't help but eye Zoro, whose muscular back was turned to him. Would he and Zoro ever…?
"Oi, Curly-brow," Zoro suddenly said, startling Sanji from his thoughts.
"What?" Sanji snapped. "I'm trying to listen to robbers here."
Zoro snorted. "Sheesh, never mind then."
They stayed silent for a moment, but Sanji had to admit he was curious about what Zoro had to say. "Alright, Marimo, they're not talking about the heist anyway. What did you want?"
Zoro hummed from his position by the window. "I was just thinking… Have you ever wondered if the reason we fight so often is because we don't do what they're doing?" He gestured to the wall connecting them with the other room.
Sanji gaped at him, the headphones hanging around his neck. "You're not implying…"
"That we should have sex? Maybe." Zoro shrugged like it was the most normal suggestion in the world.
Sanji just kept staring at him, unable to form words. Had Zoro been reading his mind? He was so shocked, that he hadn't even noticed Zoro had put down his binoculars and moved to the bed.
"So what do you say, Curly-brow?" He had the audacity to smirk.
Somehow, that was enough to make Sanji snap out of it. "Like hell I'd ever have sex with you!" he spat. "You know why we fight all the time? Because you're an idiot and a stubborn Moss-head!" His cheeks flushed – from anger, mind you – he was panting after his rant.
"Is that so?" Zoro all but growled. His voice was somehow deeper than usual, making the hairs in the back of Sanji's neck stand up straight.
"Y-yeah!" he brought out, not as confident as he would have liked.
"Or maybe because you're a love-struck fool," Zoro replied.
"Neanderthal!"
"Love-Cook!"
The next insult was muffled when suddenly their lips were pressed together, and Sanji's back hit the mattress. Sanji fisted his hand in Zoro's short, ridiculously coloured strands, keeping him close. His headphones had fallen next to him on the bed.
Suddenly, though, a crackling voice sounded: "…Time for the heist."
Sanji shot up, almost headbutting Zoro in the face. "The robbers!"
Zoro scrambled to his binoculars, grabbing the walkie-talkie. "They're on their way! Move out!"
They cast each other one last look, both looking like a mess with their shirts half open and red, swollen lips, before they sprung into action. As he ran after Zoro, Sanji couldn't help but feel sorry for the robbers. Now that he and Zoro had been interrupted, their pent up sexual frustration was through the roof. The poor diamond thieves didn't stand a chance.
