This bold is going to be shorter than others due to not much happening around me honestly and thankfully. I'm such an accidental prone person this is just wonderful to go without injury or something happening for a bit. Enjoy your day!

"Yeah who would want a captain who acts like a child?" Nami teased as she smiled and shook her head.

"A captain shouldn't put his crew in danger all the time either." Usopp chipped in.

It was all just to tease their captain who was on a rampage about being the pirate king, and in turn talked about being the best captain. Of course they all respected him and joined his crew because they wanted it to come true, but it was always fun to watch him puff out his cheeks and pout. Everyone but Chopper and Robin was pitching in, just to see him try to refute it and hold out his arm as if to show his strength as a captain.

"Fine! I'll just go to a stronger crew then! Someone who will appreciate me!" He shouted, his cheeks red with embarrassment.

Before any of them could tell him to stop Luffy grab the extra boat they always keep close and jumped aboard. He kicked his ship and let the wind catch the sail, pulling him away gently.

"Oi! You're just going to get lost!" Nami said, running to the side of the ship and staring at him in disbelief.

Luffy glanced back at her from the corner of his eyes and snubbed her, sticking his nose up in the air and huffing. He reached up to his hat and pulled at the small ribbon that was around his straw hat and slipped out a small square piece of paper. He held it out in his hand and waited for it to slightly tug in the direction he needed. He breathed in deeply, ballooning himself until he was full and then let it out, pushing his small boat quickly in the correct direction.

Nami let out a sigh. She put a hand to her head and walked back towards the center of the ship. "He'll be fine."

"How do you know?" Chopper asked, worried for his captain.

"I saw the vivre card. He's heading towards Ace." She explained, knowing what she saw in his hand before he whisked away. She was still a bit worried on him getting lost or causing trouble on his way, but when he set his mind to things there was no way of stopping him.

"Perhaps you went a little too far," Robin said, sipping tea from her cup as she sat at the table.

"Yeah, I think so." Usopp said, dipping his head down in regret for joining in.

"He'll be fine." Zoro grunted out, going back into his sleeping position and dozing off.

"Uh, Ace… you have a guest!" Marco shouted, sticking his head into the food hall where everyone was beginning to gather.

Ace turned around to look at Marco, his face contorted into confusion. But before he could ask who he was interrupted. "ACE!" Luffy sprung past Marco and launched himself through the air towards his brother. Ace couldn't react fast enough in time before Luffy was wrapping his arms around him and latching on like a baby monkey.

"Luffy?!" Ace shouted, barely grabbing onto the table to save himself from falling backwards to the floor with his brother. "What are you doing here?!"

Luffy leaned backwards once Ace righted himself, puffing his cheeks out again while looking at his brother. "They said I wasn't a good captain."

Ace blinked his eyes as he looked at the childish behavior of his brother. He let out a sigh and ruffled his hair since his hat had fallen to his back. "They were just teasing you." He knew Luffy's crew well enough to know they wouldn't say something like that seriously to him.

But Luffy had already closed his mind off to reasoning. Instead he followed Ace around the deck for the rest of the day like a duckling following its mother. It made the crew laugh though seeing Ace acting like a big brother, rather than a wild child ready for fights and adventure. He mothered Luffy every time he was about to fall over something, got something on his face, or wanted to do something and nearly made a mistake.

"A different side of Ace," Marco chuckled, trying hard to not burst out laughing loudly.

But with the glares Ace kept pointing at them they soon dispersed and left him to watch over his little brother that was quiet for a good majority of the day, which was completely unlike him. Ace wasn't good with these situations. Even while they were growing up he usually threatened Luffy to stop crying like a baby or he was going to leave him behind, but in this kind of situation that wasn't the best thing to say.

"Come on Luffy, time for bed." He said with a sigh, putting his hand on Luffy's back to escort him towards the entrance towards the door that lead to all the bed rooms down below. Most of everyone was still upstairs joking and talking, but there were a few who had already gone to bed.

"I'm not tired," Luffy spoke, the first words he's said in a while. Nevertheless he walked into Ace's room and sat down on the bed; he kicked off his shoes and crossed his legs to place his hands on them and leaned slightly.

"Y'know your crew is probably really worried about you." Ace tried to comfort, taking his hat off and hanging it on a hook that was on the wall. But Luffy just puffed his cheeks out again. Ace took off his belt and knife and hung them up as well before kicking off his boots. He quickly walked over to Luffy and reached out his hand. He grasped Luffy's face between his fingers, squishing his cheeks that were puffed out before. "Stop acting like a brat and get over it Luffy."

Luffy furrowed his brows. "Mm mnmn mmmu!" Ace raised an eyebrow and dropped his hand. "You sound like them!" He repeated to his older brother.

Ace felt a stress mark thump on his forehead, a growing irritation towards his brother. "Why you!" He grabbed Luffy's cheeks once more, squeezing harder than last time and making him whine and trying to get Ace to let go. "I wouldn't be sounding like them if you showed you were an adult in some way!"

"I can!" Luffy shouted, jerking Ace's hand away from his face.

"How?" Ace said in a voice said he didn't believe it at all.

Luffy's eyes dart back and forth while he puckered his lips thinking. "That's a secret." He mumbled out, not really thinking of anything at the top of his head.

"A secret huh?" Ace narrowed his eyes, knowing how his brother looks when he's lying. But instead he got an idea to tease Luffy more. "Oh~ I see." Luffy looked up surprised but then composed himself and acted like he knew what Ace was talking about. "Let me see if that's true though."

Luffy's face paled because he couldn't figure out what Ace was thinking and didn't know how to prove it. He didn't like the thought of being proved he was a child. Ace reached out and grabbed Luffy's face again, squishing his cheeks, but gently this time. He pushed his finger and thumb towards his mouth, making him lips part instead of squish together. Luffy sat confused with his mouth open, but soon his thoughts were answered and he understood what Ace had been previously thought before.

Ace's tongue slipped into Luffy's open mouth, and his lips locked around Luffy's, sealing the entrance. A small feeble sound erupted from Luffy's throat, and Ace smiled into the deep kiss, proud to hear that sound. His hand loosened on Luffy's face, but the little brother did nothing to fight him off. Ace pushed off of his foot and placed a knee on the side of the bed, while pushing Luffy down in the process. Luffy's back as now on the bed, but the kiss wasn't broken. Their tongues swirled around one another and pressed against each others teeth, hitting the soft spot inside their mouths to make the pleasure from the kiss increase more and more.

Ace broke from the kiss and looked down at Luffy who was now pinned beneath him, his face tinged with red, breath labored from the lack of oxygen, and eyes glazed over. Ace's heart stopped momentarily at the sight of Luffy beneath him, shocking him by the reaction it had. But now another place was throbbing deep within him. He cleared his throat and looked away from Luffy's face, trying to stop himself before he did something more. Maybe his little prank went a little too far. "See? You aren't an adult yet."

Ace pushed from the mattress next to Luffy, but Luffy reached out and grabbed Ace's arm, stopping him from pushing away any more. "Ace…." His voice came out crack and in a breathy sound. "Make me an adult…."

The throbbing deep in Ace's pants intensified, and it was beginning to burn and hurt. He never knew Luffy could say something so mature, maybe he was more adult like than he thought. Luffy dug his fingers into Ace's skin, his nails puncturing and making a mark. "Please….its hot…." Ace could stop himself anymore. The faces Luffy was making were making it unbearable for him to control his desire either.

His fingers pushed away his vest, giving him his bare chest. His fingers made their way up Luffy's chest to his nipples that perked at the small touch. He trapped one between two of his fingers and squeezed, pinching it and making it grow larger. Ace pushed his lips against Luffy's jaw, and traveled downward along his neck and chest. A small trail of saliva was left on Luffy's skin all the way down to the top of his shorts. Ace used his free hand to grab the edge of his shorts and pull them down, freeing his cock that was already hard.

He dropped his hand from Luffy's chest and grasped his shaft, feeling the throbbing of the member copying that of his own. Slowly his mouth enclosed around the tip, and his tongue circled around the tip of the skin, sucking on the barely visible tip. He let go of the top and opened his mouth. His tongue slipped to the inside of the skin and pushed it down, letting the full tip come out. Ace put his mouth back over his cock and dipped down, taking it in a good part of the way and then using his hand to stroke the rest. He quickened his pace and bobbed his head up and down, trying to make Luffy feel better.

"Ah, Ace!" Luffy said, his hand reached down and grasping his hair tightly.

Ace quickened his pace before pulling back his head and letting Luffy cum. The white liquid spurted up onto Luffy's stomach, mixing with the sweat that was now building up on his body. Luffy's hand dropped from Ace's hair and he sat up, licking the little bit that had still gotten on his lips.

"Feel better?" He asked, a smirk on his face that said he was proud of the results. "Quite a bit came out."

Luffy stared up at Ace his face filled with euphoria and pleasure. Since when could he make such a lewd face? It made the throbbing down in Ace's pants all the worse. Ace sat back with a sigh, and tilted his head back, trying to gather himself before he got up to go take a shower. A small touch to his shorts made him jerk his head back though.

"What the…!" Ace said in a grunt, feeling the button on his pants come undone and release his throbbing and enlarged cock from the confines.

Luffy stared at his cock with wide eyes, the large member much bigger than his own. Ace put a hand to his shoulder, catching Luffy out of his thoughts. "I can't be the only one to feel good." Luffy argue, breath still raspy.

"Luffy! You don't have….NNGH!" Ace grunted as Luffy put his cock inside of his mouth and bobbed his head down lown, taking it in farther than he thought was possible. Luffy's hand came and grasped the rest of his shaft, stroking it in time with his bobbing head. His other hand however didn't like to be left doing nothing, so instead they reached out and fondled his balls through his shorts, feeling the inner hardness roll around with his fingers. "Damn!" Ace groaned, his hands going towards Luffy's hair and grasping onto it.

Luffy's tongue curled around the throbbing skin and protruded on the tip's hole whenever he went up. The burning pleasure that electrified through Ace was intense and it was more than he'd felt before. It seemed Luffy had more surprises for Ace than he expected. Suddenly the intensity hit him all at once and he felt that inner coil inside of him snap. Before he could pull Luffy's head back he erupted into his throat, filling his mouth with the hot liquid that had a salty, bitter taste.

"Sorry Luffy," He grunted to his little brother, feeling a little guilty he couldn't even give some warning.

Luffy looked up at Ace, the white liquid dripping from his mouth to his chin. A loud swallow was heard from Luffy's throat as he took down the rest of the load. A smile appeared on his face and a small laugh came out from him. "You gave out a lot too!"

Ace felt his cheeks burning at the remark. He grabbed either of Luffy's cheeks in a pinch and pulled, stretching his face out wide. "Brat," He said, but put his forehead against Luffy's, taking a breather from the sudden release of that pressure.

"Ace," Luffy cut in, making his brother open his eyes and look at him. Luffy pushed forward, making Ace lean back to straighten himself back up. "I want more."

Ace stared at Luffy with wide eyes, shocked and slightly embarrassed to hear his brother say something like that. But Luffy wasn't willing to listen to an answer before he was already standing on his knees and moving closer to Ace. He put his legs on either side of Ace, straddling him while still standing on his knees.

"Oi, Luffy! This isn't going to be easy." Ace told him, knowing from just how Luffy was reacting to all this stimulus that he probably hasn't done anything like it before. So there was no way he was prepped for that either.

Luffy nodded his head and lowered himself to Ace's lap, letting their cock's press against one another. He leaned back slightly and let out a shaky breath, feeling the nerves reacting to one another and the touch. "I know….but…I want this…..and I only want it….from you…." His breathes were getting harder to push out as his cock swelled and stood stiff once more. He moved his hips, rubbing the two together, trying to excited Ace's cock as much as his.

Ace grunted and then sighed, all rational arguments flying from his mind and leaving. He grabbed Luffy's hips and then slipped his hands around Luffy to grab his cheeks, giving a better hold on the small boy. Ace's hips jerked, helping the heat and the friction between them to go faster, and soon his cock was standing erect and hard as well. Pre-cum dripped out of both of them, coating their cocks slightly.

"Luffy," Ace breathed, letting go of one cheek and bringing his hand around. He slipped his middle fingers into Luffy's mouth, letting his tongue swirl around them and lubricate them as much as he could. He had to get him to relax before anything else. But by the pleasured state Luffy was in, that wasn't going to be a problem.

He pulled Luffy up, having him lean against his chest as his hips jerked up to Luffy still, keeping him feeling the pleasure as their cocks rubbed against each other with heat. He pulled his fingers from Luffy's mouth, and used his other hand to spread his cheeks slightly. Carefully and gently he pushed his middle finger in, letting only the top break through and then wait to see if it was hurting Luffy. Slowly he pushed it in and out, letting the hole become accustomed to the feel of something entering before he added the other finger. He curled and scissored his fingers inside of Luffy, trying to get his hole to relax and be able to take him.

"Ready?" He asked Luffy, slipping his fingers out and lifting up Luffy so they weren't pushing against one another's cocks any more.

Luffy nodded his head and let out a deep breath before lowering his own hips down to Aces cock. He could feel the tip pushing against the twitching hole, spreading it wider and wider to take in the girth of it. A deep shiver ran over Luffy, making him let out a breathy, and shaky sound with a hiss. It burned a bit from the bigger object being inserted, but it wasn't something he couldn't handle. More and more he pushed down on Ace until he was completely inside of him.

"Move," Luffy breathed, his arms wrapping around Ace's neck and head burying into his shoulder.

Ace didn't feel like he should move with how tight he was, but Luffy asked him to. Slowly he pushed his hips up and then back down, thrusting in and out of Luffy. The walls stretched every time, as if he wasn't there before, and it nearly made Ace cum right then and there. This was hard on Luffy though with this position making Ace go further inside of him each time, it wasn't the best of positions for a first timer.

"Luffy, hold on." He said, stopping. Luffy pulled his head back in shock and looked at Ace. There were tears in the corners of his eyes, confirming Ace's suspicion. He lifted Luffy up off of him and looked him in the eye.

"But Ace!" Luffy whined, wanting that pleasure he had building up before.

"It's okay," Ace told him.

He moved forward, leaning with Luffy until Luffy's back was against the sheets once more. He moved himself until he laid on top of Luffy comfortable and smiled down at him. He leaned his head down and kissed his lips deeply again, capturing Luffy in the pleasure once more. His hand moved down to Luffy's thigh and lifted his hips up slightly. He once more pressed his tip against Luffy's hole and slipped inside of him, finding it much easier this time.

"Better?" He whispered against Luffy's lips, noticing he wasn't crying any more.

"mm!" Luffy said with a smile before his hands wound themselves into his hair and pulled his head back down to him in the deep kiss once more.

Ace had to be fast though now because both of them were so near to their climax. He thrusted his hips quickly, angling his thrusts slightly to hit a certain spot that seemed to make Luffy react better before. He was right…..Luffy arched his back and moaned into the kiss every time he seemed to hit that spot, shooting hot electricity through his body. His exposed cock twitched and throbbed every time he hit that spot, showing just how close Luffy was now.

"Just a little longer," Ace told him, his hand moving to Luffy's cock and squeezing slightly down at the very end of his shaft, keeping him from letting out the fluid already.

But the pleasure was overriding the pressure caused by his hand and he squeezed around Ace's cock inside. "Ah!~" Luffy moaned, opening his mouth wide with salive causing a short string inside of his mouth. Ace sucked on the end of his tongue, pulling at it with his teeth to make the pleasure even more.

Ace pushed inside of him deeper and deeper a few more times before pushing in as far as he could and letting his own climax hit. His hand let go of Luffy's cock and both of them spurted out the hot liquid, covering Luffy's stomach, and inside of him. For a brief moment they laid there like that, letting it finish the ride of pleasure inside them.

Ace pulled out and flopped next to Luffy, smiling as Luffy rolled over and laid on top of Ace this time as if he were a giant body pillow. This was more than Ace meant to happen, but he didn't regret it in the least.

"You heading back?" Marco asked as everyone gather on the main deck to see Luffy off.

"Yeah!" Luffy said with a big smile.

Marco laughed and patted Luffy on the back. "It was nice having a guest over! Come visit any time!"

"Yeah! And it was funny watching Ace become a mother bear." Vista pitched in, chuckling at Ace who turned a playful glare on him.

"So did you forgive your crew?" Marco asked, knowing that the brothers had to be alike in the manner that grudges weren't held for long.

"Yep! Because I know they're wrong!" Luffy said, putting his hands on his hips and puffing out his chest in joy. "I know I'm an adult!"

"Oh yeah?" Marco asked, wondering how he proved himself to that conclusion with such pride.

"Ace helped me become an adult last night!" Luffy burst out, not even thinking of what he meant. It was blatantly obvious what he meant by that and all stares turned on Ace who in turn knocked a fist over Luffy's head.

"Oh did he now?" Marco said in a strained voice, raising an eyebrow at Ace. "Well we'll have to get him to help us too then."

"No!" Luffy shouted, face angry as he stepped in between Marco and Ace with his arms crossed. "I made Ace promise to only help me!"

Marco stared in shock at the smaller boy but sighed and patted his fluffy hair that was sticking up in every direction. "Alright alright."

"Luffy, you need to get back before your crew comes after you." Ace said, putting his hand on Luffy's back again and steering him towards the smaller boat that was tied to the ship. "Use this," He said, giving him a piece of paper. "This should lead you back to your ship. As long as you follow it, you'll be fine."

"What if I get lost?" Luffy asked, looking up at Ace with a mischievous smile.

"Then come back here." He chuckled, before pushing Luffy towards the railing.

Laughter was heard from the crew as Ace waved good bye to Luffy and knew the teasing was going to be brutal for the next couple times.
