So, since this was supposed to be PWP, the beginning skims through the set up. Also vague since the original idea involved a tentacle monster with aphrodisiac mucus that I didn't feel like writing. XD It will get more detailed to build to the finale, so probably considered more than just PWP.

It was like there was an emptiness inside him, a need that had to be fulfilled. Zoro thought he could endure it; after all, his indominable will was a point of pride for the swordsman.

The need had started after that incident at the last port. He wasn't even sure what happened. One minute he was talking with a guy at noon, then the sun was setting and he was alone in an alley on the verge of orgasm. Admittedly, there was a pretty clear conclusion to be drawn: roofies. But he knew his body, and he didn't feel violated. Bewildered, Zoro finished himself off and headed back to the ship, telling himself that he could forget about the strange incident.

He couldn't. The first week was the easiest to hide. It was a pang then, a slight tightness of the skin. It was simple enough to get himself off more often to lessen the need. Well, as simple as finding privacy on a ship full of rowdy pirates who were more like energetic children could be.

It was in the second week that things became difficult. He started getting aroused no matter how much he got off, and hiding it kept causing awkward situations. His crewmates were noticing that something was wrong since he kept away from everyone and lashed out at anyone who bothered him.

Eventually, Chopper took Zoro's behavior and frequent red faces to be symptoms of some disease. "Um, Zoro?"

"What?!" Zoro asked, irritated as always to be interrupted in one of his extra "naps".

The little reindeer flinched. "I just…you seem to be feeling unwell lately, and I was hoping I could help. Do you want to go below deck so I can examine you?"

Zoro bit back the reflexive response that he was fine (as well as pushing away the disturbing mental images that Chopper's phrasing brought up) and forced himself to consider it. As much as it galled him to admit it, he wasn't enduring this problem well, and it was showing no signs of stopping. And the doctor was the ideal person to talk to, not just because of medical knowledge, but also because he wouldn't tell anyone about Zoro's problem.

The thing that really tipped the scales was the swordsman admitting that this problem would handicap him in a fight. Not only would his reputation be in danger, but, most importantly, it could endanger his friends.

"Fine. Let's talk. But…no examining." The idea was just weird.

"Okay!" Chopper looked pleased that Zoro was cooperating.

As they walked to the door that would take them below deck, Usopp spotted them. "Chopper, I don't think you can cure a bad attitude! Though I once-" It only took a sidelong glare and a hand moving to the hilt of his sword to send Usopp squawking to bother Luffy instead. The girls who were sunbathing paid the incident no mind.

They settled in the male's bunkroom on the sofa, and Chopper said, "You wanted to talk but not be examined, so am I correct in thinking you already know what's wrong?"

The reindeer's clinical manner was reassuring. It helped as Zoro forced himself to explain the incident at the last port. He still couldn't look Chopper in the eye as he described the issues he'd dealt with in the last two weeks.

"So, does this emptiness come from one place? Can you tell what you need to fill it?"

God fucking damn it, this was exactly what Zoro wanted to avoid. He knew. He even had a fixation on a specific solution. But his pride wouldn't let him admit that he wanted to be filled up with a dick, much less the dick of the pervert cook. "Maybe."

Chopper was unphased by his lack of cooperation. Zoro got the sense that the doctor was clever enough that he'd already figured it out. "Well, if manual stimulation isn't fixing it, and you have a feeling of emptiness…you might need someone else to help fill you."

Zoro was confident he'd never felt this embarrassed in his life. "…the thought had crossed my mind."

"Lucky that you have friends who would be happy to help you." Was Chopper really that naiive, or was he just trying to cheer Zoro up about the daunting task of propositioning a crewmate?

Sighing, Zoro gave Chopper the analysis his mind had already gone through of his options. "Luffy and Usopp are like little kids, and, no offense, but you aren't really my type. And the shit cook isn't an option because he hates my guts."

"Well, we aren't due to reach an island until the end of the week. And Sanji doesn't really hate you, just like you don't really hate him. I think I heard Nami say you 'sublimate your feelings' for each other."

Nearly choking on his own spit, Zoro fought down the horrified protest he wanted to shout. He didn't remember exactly what "sublimate" meant, but his brain just slapped "embarrassing shit" all over Nami's words and it felt accurate.

"The witch needs to keep her opinions to herself." It came out a growl as tension rose in Zoro. He was already losing control and getting aroused in Chopper's presence; further emotional messes were unacceptable.

The reindeer stood and gave Zoro as small smile. "You need to take care of yourself, Zoro. Even if that means asking someone else to help take care of you. Sanji cares about you; I'm sure he'll help." And he left, making it sound as easy as getting Sanji to make soup for Zoro if he was sick. If only.

The shit swordsman was acting weird. He had been for weeks. Neither Sanji nor Zoro had picked a fight in that time, simply because Zoro wasn't talking to him. Any insult would get a muttered reply before the moss head walked away. Sanji had actually made an effort not to say anything to the swordsman during dinner after the idiot walked out three nights in a row and didn't come back. Stupid bastard or not, Sanji didn't want him starving to death.

Stupid bastard or not, Sanji enjoyed his company more than he was willing to let on. The cook had been raised in an environment where affection was expressed through violence and insults. It took a while after leaving the Baratie to realize that he was still living by those rules, meaning animosity wasn't his primary emotion concerning Zoro. In fact, he'd never enjoyed insulting and fighting someone as much as he did the swordsman, indicating that his exceptional feelings for the idiot were…very affectionate.

Sure, Sanji loved the ladies, but there was no denying the swordsman's physical appeal. The sharp contrast between feminine charms and Zoro's incredibly masculine allure should have caused more cognitive dissonance in his thoughts, but the marimo was just a natural exception. It had seemed strange at first, but it didn't take long for the cook to get used to the idea.

Acting on it was another matter entirely. They were crewmates, stuck on the ocean together for long stretches of time. The crew couldn't afford anything messing up the dynamics that let them live in (their own version of) harmony. Zoro hating and/or being disgusted by Sanji would ruin things. Not to mention that Sanji couldn't risk being hurt like that.

Speaking of strange behavior, the swordsman had lingered after dinner when everyone else had left. Sanji just started on the dishes, not wanting to antagonize the other man by speaking. Zoro would either say something or leave in his own time.

"Hey."

Well that was an eloquent opening line of dialogue. "Hey yourself. What's up? Luffy didn't steal all your food, so I doubt you're still hungry." Sanji cast a glance over at the swordsman, noting that he was bright red. That had actually been a normal occurrence of late, but the fact that Zoro seemed fascinated with the floorboards in the opposite direction of Sanji made it seem more significant.

There was a long pause when Zoro said nothing. Then, "I have a bit of a problem."

He was tempted to turn and look at the man, because this announcement meant Zoro wanted a serious conversation, but since the window outside was apparently enthralling, Sanji thought washing dishes with his back to the marimo might be easier on him.

"Yeah, for a couple of weeks; we've noticed."

The swordsman grumbled, and Sanji was going to say something snippy on reflex when Zoro continued, "And I need your help."

Now the cook let the dishes rest in the sink to turn and give Zoro his full attention. "What kind of help do you need?"

Zoro rubbed a hand over his red face and groaned. When he ran the hand through his hair instead of replying, Sanji was concerned. Did Zoro need him to donate an organ or something? He couldn't think of anything that would make the swordsman actually nervous and keep him from manning up and saying what he needed to.

"Look, I'm going to tell you something, and you can't repeat it to anyone. And if you laugh, I will gut you." The deadly serious tone struck Sanji hard; this was clearly something deeply personal for that threat to be legitimate and not playful.

"I promise. Your secret is safe with me. And I won't laugh." Not when Zoro was clearly putting a whole lot of faith in Sanji.

"At the last port, something…happened. I'm still not sure what. But I was talking to a guy around noon and then suddenly I was alone in an alley as the sun was going down." The swordsman's body seemed completely tense, like he was lifting an incredible weight, because he shook a little as he said, "And as I became aware, I realized I was right about to cum. Alone."

Sanji turned back to the sink, his face warm and worried that his expression would give away everything he had been keeping to himself. Never ever would Sanji have thought that he'd have any conversation where Zoro talked about cumming.

The swordsman seemed to take the cook's retreat as something else. "If you're laughing at me, I swear-"

"I'm not laughing!" Sanji said, cutting off that angry voice that sounded close to breaking. "I wouldn't laugh; that isn't funny, Zoro. That's horrible. Losing time without knowing what happened…knowing what happened probably had to do with…I'd never laugh at you, Zoro." He was surprised that he'd used the swordsman's name twice, but it was an instinctual way to communicate that he was taking the conversation seriously.

Calming himself, he turned back to the green-haired man. "I just…was surprised. Didn't know what to say. I'm listening. You were in the alley…"

Zoro had yet to look at Sanji during this whole conversation, but he hesitantly glanced at the cook before looking away again as he said, "I tried to ignore it, but it started affecting me. At first I was just extra horny. It was an easy enough problem to fix. But it's gotten to the point that I'm getting hard all the time. And the…emptiness feels more insistent." He put his face in his hands and his elbows on the table, hiding entirely as he said, "I think I'll need something more."

Sanji said nothing, because there was no way Zoro was saying what he thought he was, and the cook wasn't about to make an ass out of himself by jumping on an opportunity that wasn't being offered. Zoro wasn't asking to fuck Sanji.

"I need you to fuck me," Zoro said in a rush.

Holy fucking shit, Zoro was asking Sanji to fuck him. In the occasional fantasy he had allowed himself, that wasn't a scenario he'd let himself consider. The swordsman was so overwhelmingly masculine that it seemed impossible that he'd let another guy top him.

Time stretched by as the cook's mind went wild, until he realized that Zoro was no doubt angsting while waiting for an answer. "Yeah. Okay."

The green head snapped up to meet Sanji's eyes so fast that he was surprised the swordsman didn't get whiplash. "What?"

Swallowing nervously, Sanji said, "I'll help. If you need…if you want. Of course." There was no way he was turning down Zoro when he needed him, especially when this was the request.

(-)

The cook seemed earnest, if a bit nervous, at the prospect of helping Zoro's problem. It could just be another way to win against Zoro, though. "The same thing applies: no telling anyone. And…you can't…use-"

"Let's get this straight. This is between us. It's not a competition or reason to lord anything over each other. If we're doing this, it's going to be good. I…I never want to hurt you like that. I'll kick your annoying ass, sure, but this is different, Zoro."

There it was again. When Sanji said his name his chest got kind of fluttery, and that was damn annoying. Zoro was sacrificing enough pride already; he didn't need to be a swooning idiot like the cook was for women. Never. Even if he could privately admit that the blond man had a habit of making him feel…oddly flustered, Zoro would never show it, and he'd never stoop to swooning.

"Also, um…if once doesn't work, we'll figure something out, okay?" The cook was adorably red as he said it.

And, fuck, Zoro hadn't thought about that. What if this need wasn't something he could get rid of for good? Did he want to force Sanji to satisfy him for the rest of his life? Although, if he was honest with himself, that didn't sound horrible. Well, only if Sanji was willing. It was alarming how quickly after the blond man agreed that this arrangement became much more attractive than daunting. Like maybe there was something here that Zoro hadn't allowed himself to believe he could have.

Throughout the conversation, he couldn't help but notice that the cook was responding remarkably well to everything Zoro said. Listening to him, not laughing at him, and, most importantly, agreeing to help him. And the way he said he never wanted to hurt Zoro…the swordsman couldn't help but wonder if maybe Sanji felt something for him too.

Now that they had established that this was happening, Zoro's persistent erection was getting painful. He bit his lip to keep from moaning as he quickly palmed himself. Realizing that he had done so in front of the cook was embarrassing until he realized he'd be doing something a lot more intimate before too long.

Of course Sanji had noticed. "Right now?"

Zoro barely had time to panic before they both heard, "Sanjiiii! I'm hungryyyyyy!" Saved by the Luffy.

The cook moved in a flash, kicking their captain out the kitchen door as soon as he came in. "I JUST FED YOU! GET LOST!" He locked the door after that.

"Maybe not right now," Zoro said. Even if the rest of the crew had turned in for the night, Luffy had first watch. "Saved by the Luffy" would quickly become "cock-blocked by the Luffy" because the kid would be interrupting every half hour at least to try and get food. The swordsman didn't want to be rushed as he tried to figure out gay sex for the first time. He knew the theory, but he was pretty sure the ladies' man didn't, and that meant neither had practical experience with men.

Sanji returned to eye Zoro closely, finally letting his gaze rest on the swordsman's clothed erection. "But you clearly need something."

"I'll deal with it until we have an opportunity-" Zoro cut off with a gasp when Sanji's hand rested on the bulge in his pants.

The cook was bright red and trying to look confident when he said, "I think working our way up might not be a bad idea. Then we won't have to jump right to the top. You want me to touch you, right?"

Zoro could only nod emphatically. Sanji grinned. "Go ahead and take your shirt off so it won't get dirty." While the swordsman obeyed, the cook pulled his pants down enough to free his erection. Gasping, Zoro's eyes fluttered closed when that skilled hand started stroking him. Almost immediately he began trembling; God, it had been so long since he'd been touched by anyone else, and he was desperate.

"Um, if I can't…" It shamed him to even mention it, but from the second Sanji touched him, he knew it wouldn't take long.

"Cum as soon as you're ready. You need this pretty badly, don't you?" The blond man's voice was soft and reassuring. It made Zoro forgive himself, at least a little, for cumming almost right after he was given permission.

Muscles tightening in release, warm wetness spilling on his chest and stomach, pleasure flooding through him in waves…it had been too long since an orgasm felt that good, and given how much he'd been masturbating recently, that said a lot. And he was pretty sure he heard the cook's breath hitch when he let out a low moan as he came. It reminded him of something as he panted and came down from his high.

He eyed the cook. "Want me to touch you?" When Sanji looked immediately hesitant, he added, "Fair's fair. Come on."

When he was given a nod of assent, Zoro wasted no time in opening Sanji's pants and freeing his cock. While Sanji had been very gentle, the swordsman applied force. Not giving the cook a chance to sit down, the blond man standing over him, Zoro took a firm grip and stroked.

He was delighted that Sanji had trouble keeping quiet, moaning wantonly before biting his lip. His expressions were wonderful as well. No reservations, all startled surrender and helpless pleasure. As incredibly arousing as he found the cook, Sanji was also undeniably adorable.

"Zoro…fuck, please. Faster. Harder." Sanji was gasping, hips thrusting. His hands had settled on Zoro's shoulders and were gripping tight.

The swordsman obliged, pleased when moments later, Sanji let out a gasping groan and came all over Zoro's chest. It was by design; Zoro figured he already needed cleaning up.

The cook said nothing as he relaxed, just panting. When he caught his breath, he whispered, "Oh my God. Someone finally touched me." It was barely more than a breath, but Sanji looked immediately stricken, like he hadn't meant to say that aloud at any volume.

That was nothing Zoro ever expected to hear from the love cook. "Wait, you're a virgin?"

When Sanji tried to turn away, red-faced and ashamed, Zoro stopped him with a firm grip on his arm. "Hey, we established nobody is laughing at each other. There's nothing wrong with it. I just didn't realize." It actually meant a lot that Sanji was willing to do this with him to help him out. Of course… "You sure you want to do all this with me?"

Sanji started doing up his pants. His eyes met Zoro's for a moment before he said, "Yeah, I'm sure."

And maybe the swordsman was crazy, but he would swear there was something in those eyes that was trying to tell him that this was something more than a favor. Maybe he was overly hopeful, but it felt like it was real.

"You need cleaned off. Give me a second." Sanji moved to get a dishrag and wet it in the sink before he gently scrubbed off the rapidly drying cum coating the swordsman's torso.

When he was cum-free, Zoro put his shirt on again. He stood up and said, "So, should we discuss this more tomorrow?"

"Sounds good," the cook said, turning back to his dishes.

Not sure what else to say, he bid the blond man good night and unlocked the door to walk out on the deck. And found Luffy waiting, leaning against the wall by the door. "You guys realize the galley has windows, right?"

Zoro's stomach plummeted. So much for keeping this between the two of them. He'd closed the door behind him, so maybe he could do damage control without upsetting Sanji. "You were watching?"

Luffy looked matter of fact as he nodded. "You weren't really quiet either. Someone else might have heard."

The swordsman wasn't sure what to say. "Don't say anything to anybody, okay? We want to keep it between us as long as we can."

"Okay." Simple and honest, that was Luffy. "But if I mention this to Sanji, do you think he'd feed-"

Without warning, Zoro was pressing Luffy into the wall. "You aren't going to embarrass or extort Sanji, or I will cut you. Captain or not, friend or not." He didn't realize how true it was until he said it. He loved his idiot captain and would die for him, but he also wouldn't tolerate anything against their cook.

Luffy's face split into that crazed, shit-eating grin of his. "Good!"

After a beat, Zoro got it. That was the grin Luffy employed when he was being his version of clever. "Wait, that was a test?"

"Yeah!" Their captain giggled, and his smile melted into his normal happy-go-lucky one. "After all, if anyone in my crew is going to date, I have to make sure it's good. Zoro will treat Sanji right."

Letting out a sigh, the swordsman said, "You know I will. I'm going to bed. Night, Captain."

(-)

Sanji's heart was still hammering from what had happened between Zoro and himself when he heard the exchange with Luffy outside the door. The panic and embarrassment of knowing they'd been seen quickly faded as Zoro stood up for him, going as far as to threaten Luffy. They all knew that Zoro and his captain were probably the closest people on the crew, having been together the longest. The short-tempered swordsman would put up with almost all of the captain's shenanigans without much protest. They understood each other better than anybody else. Sanji wouldn't lie; it made him jealous. So Zoro threatening Luffy on Sanji's behalf filled him with a warm glow.

Of course, Luffy came into the galley moments after Zoro left. "Hiya, Sanji!"

"I know, I know: you're hungry."

"Always. But I also want to talk about Zoro. You heard us, right?" The captain was so serious and matter-of-fact that it was spooky.

Sanji turned his back to the sink as he dried a dish and peered at the boy. "You know, it's unnerving that I can never tell how much of your crazy and stupid is an act to cover this sort of behavior."

"What do you mean, Sanji?" Luffy seemed quite honestly confused, innocently so. He was an enigma wrapped in a riddle slid inside a turkey roasted in an oven and stuffed into a rubber man. Really, Luffy was just what one would call "selectively serious". Probably a side-effect of the kid being so up-front and honest. If something needed saying, he'd say it.

"Nevermind. What about Zoro?" Sanji didn't want to talk about anything he didn't have to. Luffy had mentioned "dating" to Zoro, but he clearly didn't hear the discussion before things escalated.

"You two want to have sex."

The cook dropped the plate he'd been drying on the floor, the crash timed perfectly with his mouth dropping open a little. "Selectively serious" or not, that was not a word he thought he'd ever hear from their captain. It's not like he thought the kid was totally ignorant, but Luffy was always such a kid that Sanji figured he didn't pay attention to anything like that. Luffy didn't pay attention to girls, Luffy didn't pay attention to guys; Luffy paid attention to his dream and his crew.

"Did you not hear what we were talking about?"

"After you kicked me out, I came back and heard you say something about Zoro needing something." Luffy shrugged. "Looked like you both needed it."

Sanji was pretty sure he could bake his head in an oven and not achieve the heat in his face. Luffy had watched that. And, as Sanji thought, it didn't really register to the rubber idiot that what happened was supposed to be private. Though his comment to Zoro that the galley had windows was fair; they should have been more careful.

Of course, Sanji had promised Zoro that the swordsman's situation would be between the two of them. That meant if Luffy hadn't heard, Sanji couldn't tell him. "Look, it's not that serious. It's not like we're dating, so just let this stay between us."

"Zoro doesn't do anything he doesn't believe in."

Those earnest words struck the cook. It was true. The marimo was an "all-in" kind of guy. But he came because he needed help from Sanji, not because he wanted Sanji in particular. Considering the other options, the swordsman probably considered Sanji the least offensive. Which, while neither quite an insult nor a compliment, wasn't encouraging.

"He doesn't 'believe in' me, we're just-" Sanji was cut off as Luffy started giggling.

The kid looked so incredibly pleased as he said, "You're crazy, Sanji. He was serious about hurting me if I did anything to hurt you. Otherwise, I know Zoro would never do anything to hurt me. If you're the exception, you're important. So don't say dumb stuff."

Picking up the broken dish to hide how flustered that made him seemed like a good idea. Luffy was right. Sanji had just been flattered at the gesture, had known it was an insane notion that the swordsman would ever hurt his beloved captain, but he hadn't truly thought about what it meant on a deeper level. Zoro didn't do anything he didn't believe in. How was the stupidest kid Sanji had ever met also so perceptive?

Must have been the (relatively) ideal allocation of Luffy's very limited brainpower. His best mental efforts were brought out when he had to think of some way to beat an impossibly powerful enemy. And, apparently, when he wanted Zoro and Sanji to understand each other. The rest of the time his brain rested so it didn't burn out by thinking about anything other than food, fun, and becoming King of the Pirates.

The cook sighed. "I'll make you a little more food." When Luffy's cheer died down, he added, "And then you're going to keep watch."

"Okay!" Luffy said.

Sanji pulled out some ingredients and turned on the stove, all while planning how to seduce a shitty swordsman.

I really need to finish one thing before starting another, but this is turning out to be too long for a comfortable one-shot, at least in my opinion. So I've posted what I've got so far to see if anyone enjoys it. I need to finish my other fics.

Anyway, I hope you liked this. Feel free to review if it pleases you. This is my first fic for this fandom, and hopefully it isn't too OOC.
