A/N: This is literally just started as an excuse to have Deuce be banged by a bunch of people. aaaand then I started adding feels for some reason. Enjoy.

The day was surprisingly calm, quiet. Usually, finding peace while doing paperwork was just about impossible. Deuce had grown used to the fact that one person or another was going to be screaming bloody murder at any given second. It was usually as a direct result of one of Ace's pranks or Haruta running around stealing everyone's personal belongings.

Deuce didn't question the silence. He just rushed to get paperwork finished as quickly as possible. Marco needed these reports yesterday but everything had gone to hell when some idiot Marine captain had tried to attack the Whitebeard crew. Deuce's poor paperwork had been smacked out of his hands and then flew overboard. The young doctor had to rewrite them all so he could turn them in.

"Still working?" A calm voice asked from behind him. He felt fingers move to play with his hair. They were gentle and meandering, as if trying to pick something out of his long hair. As they drifted to the back of his neck, a pleasing jolt sparked down his spine and he bit his tongue to keep from gasping.

"I wanted to get this done before anything happens to this batch." Deuce urged, looking up at Marco. The commander just nodded in acknowledgment. It was then that Deuce noticed the cup in Marco's hand. "Tea?"

"Yes." Marco looked down questioningly at the pale lavender liquid. Steam pleasantly flowed from the top of the cup. The air was filled with a sweet aroma. "A new variety from the nearby island."

"I never took you for enjoying sweet teas."

"I don't. But I don't like Thatch keeping new supplies in the kitchen without me checking if they are safe first." Still, the overtly sweet smell of the drink was causing the blond to wrinkle his nose in distaste.

"I'll drink it!" Deuce suddenly offered. He smiled up at the commander and reached out his hand for the cup.

"It could be poisonous for all we know."

"Well, you'll be here watching me. If I have a bad reaction, you'll be right here."

Marco frowned at the offer but still considered it for a long moment. He supposed that there was indeed a logic to the younger man's suggestion. "Alright. I suppose there isn't much harm to doing things that way. The natives of the island did say 'the tea is a pleasure'."

Deuce smiled as the cup was gently placed into his hand. He was careful with the hot porcelain as he grabbed the handle. He gave the liquid a sniff before eyeing it suspiciously. It seemed safe enough to drink.

Marco pulled up a chair and sat beside Deuce's desk. He reached across the pile of vaguely full journals, grabbing one of Deuce's neglected notepads. He scribbled at the top that he and Deuce were conducting experiments on the new tea.

A voice in the back of Deuce's head told him that drinking an unknown substance from a new source was a very stupid idea. But, what was the worst that could happen? The best doctor on the crew was right beside him.

Deuce pressed the rim of the cup to his lips and slowly sipped the tea. His expression lit up as the taste filled his senses. It truly was a pleasure to drink. It was sweet and soothing as it flowed over his tongue. The flavor was rich but not to the intensity that would make the drinker cringe. He started to drink down the rest, surprising both himself and Marco.

"This tea is delicious, Marco!" He exclaimed. He put the cup down on the table but still nestled between his hands. "The people who gave it to Thatch weren't kidding. Total pleasure!"

Marco paused and scrutinized Deuce for a moment. The younger man seemed different compared to normal. He appeared perkier and more openly expressive about that perkiness. "Are you feeling alright?"

"I feel great!"

"Hmm." The phoenix picked up his pen and started to scratch out a few quick notes. Whatever this tea was, it must be a stimulant of some kind. He would have to monitor the younger doctor for side effects.

"Sure is warm today."

Marco paused and looked up from his notes, eyeing Deuce questioningly. His gaze drifted down to his companion's hands, watching strong fingers fidgeting and tapping the cup in Deuce's hands. He could feel the vibration of Deuce's knee repeatedly bouncing against the underside of the desk.

"We are anchored on the border of a winter island, Deuce." Marco squinted suspiciously at the younger doctor. It was quite a cold day. Even he could feel it through his normally high core temperature. He was concerned about why the younger man was feeling warm at this time. But a fever may be a side effect of the tea and that in itself was concerning. He would have to monitor the younger man.

Reaching out, he pressed his hand to Deuce's forehead. His jaw set in unease. Usually, his crew members' skin was much cooler than his own. But Deuce's was far above normal. He could already see a slight sheen to the other man's skin as his cheeks tinted red.

Marco tried to pull his hand away but froze. His eyebrows raised slightly in interest as he suddenly felt Deuce's lips against his wrist. The young man's eyes were closed and his head was tilted back. The tip of his nose rubbed against the side of Marco's hand as his hot lips kept dragging kisses over the commander's wrist.

Deuce seemed to be lost in the sensation of doing the act. Marco was at a loss for words and couldn't seem to pull his hand away. A strange fluttering formed in the phoenix's chest as he watched his companion, just soaking in the moment. Small sparks of feelings long smothered were started to flicker once more. Longing made his heart ache.

"Deuce?" He forced himself to speak.

"Huh? Yeah?" The young doctor murmured before opening his eyes. His vision filled with the sight of Marco's hand. He could feel Marco's skin against his mouth and the sensation made him jolt back. His eyes grew wide as he looked over at his commander, horrified.

"M-Marco, I'm so sorry!" Deuce's heart slammed against his breastbone. He pressed himself against the back of his chair, the furthest away from the blond as possible without getting up. His mouth opened and closed a few times as he struggled to force words out. It took a moment before his brain resumed functioning. "I… I don't know what came over me!"

Marco watched Deuce's gaze drop. The younger man's face grew redder as he refused to meet the blond's eyes. He squinted in contemplation as he took in his companion's full image, suspicion filling him. "Deuce, stop me if you grow uncomfortable."

With that, he reached out his non-dominant hand to touch Deuce's cheek with the tips of his fingers. He hummed in interest as he watched Deuce's eyes slip closed before he needily rubbed his face into the palm of Marco's hand. Marco quickly made a note onto his notepad and pulled his hand away, resulting in Deuce whining unhappily.

"Hmmm… I think I understand now." He reached over and took the cup away from Deuce's hands. He took a sip and let the tea sit on his tongue for a moment. His nose wrinkled at the sicky sweet taste but forced himself to focus on how it made him feel. A vaguely annoyed sigh escaped him as he activated his flames to burn the tea's effect out of his system. "An aphrodisiac. I should have known. Stronger than most chemically made ones it would seem."

As Marco started to write a small summary of the tea onto the notepad, Deuce started to squirm in his chair. His hands fisted and he whimpered, unsettled. His skin was hot, sweat starting to form, as a familiar ache started to pull in his lower belly. He gritted his teeth as he felt a growing heat swell between his legs. Given Marco's discovery, the erection was not a surprise to Deuce. Though it did have him regretting his choices as the new drive for sex started to intensify. But what was actually causing him to panic was the strange wet heat that he was feeling between his legs down lower than his erection.

"Marco." He whimpered. His pulse started to quicken as he reached out and grabbed his commander's wrist. Startled, Marco looked up and Deuce squeezed the blond's wrist. The younger doctor's voice was frantic as he struggled to convey what he was experiencing. "Marco, I think I'm having a bad reaction. I think my anus is bleeding."

Marco frowned, immediately becoming more clinical. He nodded and stood, heading over to his desk. He pulled out a pair of exam gloves, slipping them on. "Get undressed and lay down on one of the exam tables. I'll check it out."

Deuce swallowed tightly as he shakily stood. He nodded and made his way towards the exam area. He picked the first bed with a privacy curtain and started to undress. His breathing was unsteady as his mind started to go through every medical reason he could remember that caused bleeding from the anus. His stomach twisted as his mind clung to the most potentially dangerous medical facts. His mind was such a blur that he didn't even think to check for blood on his clothes. He simply folded them and laid down on the table. He flushed softly and bent his legs at the knees before he spread them to allow Marco easy access for the exam.

Marco walked over, hands covered in sterile gloves. He was more than a little confused when he walked over to his patient. Something familiar and longing stirred inside of him at the sight of Deuce aroused and naked on the table. He sighed, frustrated with himself and forced the feelings down. He gently spread Deuce's legs and was surprised to not see any blood on the sheets or on Deuce's skin. All he saw was a sheen of clear liquid on Deuce's inner thighs. Believing that it was excessive sweating from the increased temperature, he reached between his subordinate's legs. He gently touched Deuce's dusky rim only to pause as a long moan rumbled in Deuce's throat. Marco shifted his weight, trying to ignore the noise and focus on the task at hand.

As he was checking for damage or blood, a slick substance on Deuce's rim caused his gloved fingers to slip. Startled, he pulled his hand back out of curiosity. He lifted his hand to look at his fingers, that clear substance was all over them. Terribly confused, he rubbed his fingers together. Whatever it was, it was much more slick than any known bodily fluid. In actuality, it had a consistency closer to that of manufactured lubricants.

This was starting to make a very confusing kind of sense. He had a hypothesis and the very concept was one that he was having a hard time swallowing. Still, ever one to take in as much knowledge of anatomy as possible, he moved to find answers. His hand returned to the area between Deuce's legs and carefully stroked over his entrance. Copious amounts of the mysterious liquid coated his gloves and he found himself squirming a bit from the filthy sounds that Deuce expressed at the touch.

"Deuce, I'm going to check something. Tell me if it starts to hurt." Marco said flatly. He was trying to stay clinical about this entire situation despite the very real fact that his pants were starting to feel a little tight with each passing second. This day was getting more ridiculous by the second.

Deuce had to admit that Marco's words actually kind of scared him. How bad was he that this was going to hurt?! How bad could it be? Those previous touches had felt so amazing. Each touch has sent sparks up his spine as his mind blanked for a solid thirty seconds. His cock was hard and dripping all over his belly and he honestly didn't give a fuck anymore. He really just wanted this medical exam to be over so that he could scurry off to his room and jerk off in secret to his picture of his commander talking to Ace.

A strangled sobbing gasp suddenly wrung itself from Deuce's throat as he felt his ass slowly stretch around a sudden intrusion. He moaned, fingers fisting in the sheets as his hips jerked up before pressing back on that on the wonderfully penetrating finger. His eyes rolled back as he started to pant, each breath causing his whole frame to quake. His cock jerked as he sobbed. "O-oh! F-fuck me, Commander!"

Marco froze as soon as those words left the other man's lips. His eyebrows quirked as he blinked a few times. He had heard a lot of things shouted at him during medical exams. They were usually along the lines of "fuck you, Marco!" but never had the words "fuck me, commander" had ever come up. This brought up a multitude of ethical questions that Marco wasn't quite sure how to answer. He knew that everything sexual about this situation was caused by the herbal compound of the tea but it was affecting him in ways that he didn't appreciate. The last thing that he needed was to cross the line with a subordinate.

He closed his eyes for a moment before forcing himself to continue on with his exam. The fact that his finger had been able to penetrate Deuce's anus without the aid of man-made lubrication meant that his hypothesis was correct and that Deuce was indeed starting to produce whatever this slicking substance was. But how? That was the true question he had to answer here.

Trying desperately to ignore the filthy sound escaping Deuce's mouth, Marco tried to keep working. He had to force his eyes closed when he found that they kept drifting to the younger man's twitching erection. Filled with guilt over inspecting his subordinate in a sexual fashion, he clenched his eyes shut. He turned all of his focus to his finger and what he was feeling inside of his patient. Concern and confusion started to feel him when he felt something that felt like a group of glands inside the tight passage. The buildup of slick was in that area and logic told him that the glands were actually producing the lubricant. But he swore that he hadn't felt them the last time that he had given Deuce a proper prostate exam.

He carefully touched over the glands, inspecting them as best he could by touch. He moved his finger too much and pressed down a bit too hard. He jolted, eyes snapping open and looking over as Deuce suddenly cried out and arched up. The young doctor jerked, reaching orgasm, and cumming all over himself as his commander watched in shock. Marco found himself unable to move, just awkwardly standing there as his patient collapsed on the bed and murmured happily.

"The fuck is happening in here?!" An annoying familiar voice called out with deep concern. Thatch hurried around the privacy curtain to check on his crewmates and stopped in his tracks. His eyes widened a bit at the sight of a very naked and cum-coated Deuce laying on the bed. Marco standing with his finger between the younger man's legs, looked quite incriminating.

A teasing snicker escaped Thatch as his stance relaxed. He crossed his arms and smirked at Marco, shooting him a knowing look. The expression was most unwelcome and caused Marco to frown.

"Don't be childish, Thatch." Marco huffed as he carefully started to remove his finger from Deuce's still quivering entrance. "It is perfectly natural for men to accidentally reach orgasm during a rectal exam."

"Yeah, sure. How many doctors have used that line before after being caught with a patient painted in cum?" The chef wiggled his eyebrows at the doctor, grinning.

Marco closed his eyes and sighed, trying desperately to ignore him. He shifted his weight as he carefully pulled off the glove. He swallowed thickly, refusing to move out from behind the table. He could feel the full erection in his own pants and really was not in the mood for Thatch to see that. More commentary on his medical practices was the last thing he wanted right now. He threw the gloves in the trash and pulled on new ones, starting to clean Deuce up as the younger doctor murmured blissfully.

"Unless you want to explain a bunch of horny crewmates to Pops, I wouldn't give anyone else that new tea," Marco warned. Once Deuce was cleaned of cum and "slick", Marco pulled a blanket over the younger man.

"Wait." The sudden topic shift took Thatch off guard. He frowned until he remembered that he had locked the tea away until he was sure it was safe for consumption. "What does this have to do with the tea?"

"It's an aphrodisiac."

"Oh. Oh!" That god awful grin was back. "So that's what happened here!"

"Nothing happened here," Marco replied flatly. "This was a standard medical exam."

"Oh really?" Thatch walked around the bed and pulled Marco away from it, exposing the blond's lower half.

"And uh, is that standard for medical exams as well?" He snickered, pointing at the very obvious tent in Marco's pants. "I've been missing out."

Red starting to spread across his cheeks, Marco shook off Thatch. He fixed his sash, shifting it down to hide his erection. "That's enough. I have work to do. I believe that Deuce has formed special glands used for self-lubrication. I have heard of rare cases but believed them to be hoaxes as they usually need a catalyst in order to grow them. It sounded fake but I was wrong. The tea appears to be a catalyst for them."

"Self-lubrication?" Thatch hummed and stepped closer. He pressed up against Marco as his hand settled on the phoenix's hip. He hummed softly, leaning and nibbling Marco's ear. "That'd sure be handy. You should take that tea so that your tight ass could keep up with your stamina finally."

"You two're together?" Deuce's dazed voice startled both older men and they quickly stepped away from each other. Deuce was leaned up on one arm, looking at them. He frowned, expression sad. He hadn't meant to ruin their moment.

"Deuce, my apologies." Marco cleared his throat and straightened up. "I figured you would be out for a while after reaching orgasm."

"O-oh." Deuce shifted uneasily, fidgeting with the sheets. His skin felt so hot as his insides quaked and quivered in need. He clenched his eyes shut and slowly sat up, pushing off the blanket. His skin was flushed and his cock still fully erect. He swallowed down the anxiety twisting in his chest as he whimpered, looking at the two older men shyly.

"C-commanders…?"

"Yes, Deuce, what is it?" Marco replied, shifting to get comfortable while still trying to appear professional.

"Will you fuck me, please?" The question took both men by surprise. Marco could only blink but a sly smirk pulled at Thatch's lips.

This was going to be fun!
