“P...pull out! Shit, the last thing I need is your cum dripping out of me when I'm trying to make breakfast for everyone.” He groaned; he could tell Zoro was going to cum, could feel the other man moving faster inside him, against his overstimulated prostate. It was almost uncomfortable, but deep down, he liked it. Liked finishing first and letting Zoro fuck him until he was done, no matter how sensitive he had become.

“Sh...shut up. Fuck! You know you love it.” Zoro gripped him tighter, shoving his cock inside like he'd die if he pulled out, moaning loudly as he released inside of his hot and sexy companion.

“Asshole, can't you listen to me for once?” Sanji panted out, wincing as Zoro slowly pulled out, the moss heads' gaze lowered to where they were connected.

“Hmm, gonna cum inside if I want you round with my child, eh, curly-brow?”

Sanji's mind went completely blank, like fuzzy static inside his head, not allowing him a single thought. Zoro had been completely serious.

“Wh...what the hell are you even talking about?”

“What? Don't want my kid?” Zoro asked as if it were the most normal thing in the world.

“You...moronic ape! I'm a man, you know it's not possible!”

“Tch, a man can dream, can't he?”

After the first time, Sanji learned very quickly that Zoro had a bit of a breeding kink. It was...definitely interesting, and made Sanji a bit worried at first, knowing, in reality, he could never actually give Zoro what he fantasized.

“Tch, I know that. Can't a man enjoy a kink without being judged?” was Zoro's answer. He didn't seem worried.

“I'm shocked your empty head even knows what a kink is.”

It was...an odd thing, but really, Sanji didn't mind obliging to Zoro's desires. To his fantasies. Even if, to him, it was a little weird. No harm in it. And he knew, if he really didn't want to deal with it, Zoro would stop.

“Hey,”

“Hmm?”

“Wanna fuck? We can...see if I can put a baby in you this time.” Sanji blushed at the ears. Just slightly. Shit. Why did it turn him on though? The thought of Zoro getting him pregnant.

“Yeah, show me what you got.”

“Hey! Stop that!” He liked facing Zoro while they fucked. Liked locking his eyes with Zoro's eye. But when Zoro suddenly was manhandling him and basically bending him in half, cock still buried deep inside of him, it took him by surprise.

“If your legs are raised, it'll increase the chances of getting pregnant,” Zoro grunted, nipping at his neck, purposely leaving marks.

Sanji was sure that was a myth, but it couldn't hurt to try, right? Let Zoro have his fun? Plus, he could feel Zoro get deeper inside of him. Each thrust hits his prostate dead on, sending pleasure coursing throughout his body. Fuck, Zoro knew his body too well; it was almost embarrassing at this point.

“S...sure.” Sanji moaned, hand fisting Zoro's hair as the man continued his onslaught of marking his neck. There were going to be so many marks, but at this point, Sanji didn't care. Between his neck being kissed (his weakness) and the constant harsh and quick thrusts against him, he was in heaven. Zoro's fat cock always hit him in the right places.

“Can't wait to see you full with my kid.” Zoro moaned. Sanji could tell by the way Zoro was thrusting into him, desperate, quick, that he wasn't going to last long.

“C...cum inside, come on, get me pregnant just like you want!”

Stressed.

Sanji was stressed to say the least.

They were almost out of food – no thanks to Luffy – and they were still two days away from the next island. He could make the food last, but Luffy would complain about the smaller portions and not being able to get seconds.

“Hey,” Zoro's gruff voice caused him to look over, a huge pile of fish dropped onto the table.

“What?!”

“Don't stress out, it's bad for you.”

“Bad for...me?”

“Yeah, stress messes with your fertility. And we don't want that....do we?”

“Uh....” Sanji blinked in confusion. Zoro really never mentioned his..kink outside of sex. So this was...a first.

“Chill out. We'll be fine.”

“Sure, thanks for the...fish?”

“You can thank me later by letting me fill you up with my cum and giving me the baby I want.”

“Have you...ever not cum when I fucked you?” They were fucking again right now. Sanji riding Zoro's cock like he was made for it. But those words made him pause a moment in shock. Zoro's hands gripped Sanji's hips, moving his own so he could thrust up into him.

“Why-ah! Why did you a...a...ask that?” He wanted to take control now, but Zoro seemed to have other ideas. Holding him steady as he thrust upwards into the tight heat.

“Well?”

“N...no! You al...always make me cum! Always! Fuck moss head.” He moaned, moving his own hips to meet the intense thrusts of Zoro.

“Good, you need to have an orgasm if you wanna get pregnant.”

It was almost getting a little weird now, but also kind of endearing. Zoro would find him randomly on the ship and pull him into his arms. Whisper sweet nothings into his ear, tell him what a great dad he'd make. Ask him if he thinks they'd have more than one, the first time, since Sanji was a quadruplet.

“Fuck, I'd hope not!”

It was then that Sanji realized he was getting a little too into Zoro's fantasy.

“You...know I can't actually get pregnant, right?” He gasped as he felt Zoro shove his fingers inside of him, mentioning something about 'gotta keep it inside you if you want a baby to form'.

“Never say never,” Zoro smirked as he slowly pulled his fingers out, seemingly satisfied with his work.

“Maybe it'll happen now. We fucked three times, and I made sure to stay inside you long enough.”

“Zoro,” Okay, time to be serious. “Do...you want a kid?”

“Yeah, I want three. Kinda my thing, y'know.” Yeah. Three swords. Three earrings. It didn't really surprise Sanji, really.

“T...three?!” Sanji wasn't even sure he could handle one kid, let alone three!

“Yeah, why not? You don't think we'd make good parents?”

“Of course we would...but Zoro...come on, you know I'm a man. I...don't have those parts. I can't actually carry a baby, or any of that.”

“I know,” Zoro sat up, pulling Sanji against him. “And that's fine. I just think it would be hot if you could. Don't worry, curls, I'm not stupid. I just like to pretend sometimes.”

They were on a new island. Only for a day and a half to restock. They were going to spend the night, and leave early the next morning. Sanji already commandeered Zoro to help him gather supplies for meals, while the girls went shopping together.

“Do we really need all of this shit?!” Zoro asked, arms filled with bags and tied boxes. They were already on their way back to the ship.

“Of course we do! Every single thing I've purchased is with purpose! You know I don't waste food!”

“Alright, but when can we go get some booze? This is boring.”

“Once we get this back to the ship. Then the night is yours, then. We can do whatever you want.”

“Oh? Anything?” Zoro smirked. Sanji made a sound between a sigh and a laugh. Here we go. He knew what was coming, and he couldn't hide his smile and laugh.

“Think I can fuck a baby into you tonight?”

“Sure, we can try.”

Several yards away, an unknown, cloaked figure stood in the darkness. Listening to their every word.

“Interesting.”

Sanji always underestimated how much Zoro could drink. It never ceased to amaze him, honestly. He had lost track of how many beers and how much sake Zoro had had already.

While Sanji nursed his third peach cocktail. He hated to admit it, but he was feeling the drinks. Nothing bad yet, just a nice, happy buzz. And that was what he liked. Teetering between being tipsy and drunk.

“Oi, Zoro.” He called out. Zoro and Usopp were taking a shot of...some sort of alcohol together. But Zoro trailed right over to him.

“Yeah?” His cheeks were flushed red, just a tiny bit. Ah yes, Zoro was feeling the alcohol. At least a bit.

“Let's ditch this place.”

“Hmm?”

“...Let's get back to our room and...try for a baby?” Sanji offered. Sometimes he felt so incredibly stupid saying it. But it made Zoro happy, turned him on, and that was all that mattered. He liked seeing Zoro happy, liked indulging in his fantasy.

Zoro perked up at the idea, grabbing Sanji's hand to pull him from the seat and wrapping his arm around him. “Yeah, let's go.”

The walk to the inn was quick, and easy, although Sanji took the lead, because even in the short walk, Zoro would have gotten lost.

They were only paying attention to one another, random kisses and dirty words, not looking at the cloaked figure walking towards them, walking straight in Sanji. Hard.

Sanji gasped, falling backwards, and being caught by the cloaked figure's hands around his waist. Time felt like it stood still for a moment. A weird, hot, and tingly sensation coursed throughout his body, momentarily making him feel dizzy.

“Hey! The fuck is your problem, weirdo!” Zoro yelled, and the cloaked figure was shoved to the ground, Zoro's arms around Sanji to help him stand.

“My apologies, good sirs. Have a wonderful night.” A smirk behind the cloak, and he was gone as quickly as he had appeared.

“Are you....alright? You look flushed.” Zoro said, brushing Sanji's hair from his face.

“Y...yeah, I'm fine. Come on, let's get to our room.” Horny...He was suddenly so fucking horny, and all he wanted was Zoro's perfect dick inside of him.

“Fuck me! What are you waiting for?!”

“Patience love cook. Gotta make sure you're prepared and nice and wet for me.” Zoro kissed him, slowly pushing in two lubed fingers inside of him, causing a deep gasp from Sanji. He always started with two. While he wouldn't say Sanji was loose, he was able to take it easily enough, given how much the two of them fucked.

“Hmm?” But right now something was...different. He seemed so much hotter...tighter, and wet? How was that even possible?

“Please...please!” Sanji begged, squirming under Zoro's grasp, tightening around his fingers, like he wanted more. Sanji never begged like this. Like he was desperate for it. Like everything Zoro was doing wasn't enough

“Hey,” Zoro said softly, pulling his fingers out, looking at his work, Sanji's wet, twitching entrance. Hmm, odd.

“You sure you're okay?”

“Yes, never better, now fuck me! Get your cock inside of me and knock me up!”

Zoro shrugged to himself. Who was he to deny the love cook while he was lying underneath him, practically begging for his cock, begging to be knocked up. He loved it when Sanji indulged him like this.

“You want me to knock you up, Love cook?” Zoro cooed softly, gazing at the strong man underneath him. Sanji's face flushed with arousal, cock incredibly hard against his stomach. Zoro decides to take his time for a moment, and kisses the crease of Sanji’s thigh, relishing in the strong muscles and spreading Sanji’s legs with his hands. Sanji follows the motion easily, allowing Zoro to expose him. His entrance already prepared, more than ready, desperate to be filled. To be bred.

Zoro lines himself up, pushing slowly into Sanji’s tight, wet heat. Sanji whines in response and wraps his legs around Zoro's hips, urging him closer, deeper.

“Fuck, you're so hot like this.”

Sanji whines again, (so unlike him, Zoro thought) and Zoro bends over him to kiss his neck, his jaw, his chest. Sanji does get a little shy about affection sometimes, still so used to them fighting against each other, but has learned quickly to relish in it and love it.

“I can't wait until you're knocked up. Will you let me breed you again, after?”

“Y...yes! You...want three, right?! Bet...better get to it then.”

“Mmm. So that's it, isn't it? You want to be my little broodmare? Maybe I want to keep you full and breed you over and over. Don't worry, I won't ever let you be empty again. You'll always be round and heavy with something moving, kicking, and growing inside of you.”

“If...if that's what turns you on, fuck, whatever you want. I'll give it to you.”

Zoro snaps his hips harder, arousal tightening in his gut. Sanji wraps his legs around Zoro's hips, tugging him in even closer.

“Fill me,” Sanji gasps. “Breed me.”

How could Zoro deny such a perfect request, especially when Sanji was an active participant in his kink? He fucks into the wet, clutching heat a few more times, hands on Sanji’s stomach, gasping as he let himself go, moaning as he comes. Sanji groans when Zoro fills him, and cums in between them, untouched, thighs shaking.

Zoro pants, withdrawing slowly, and kisses Sanji softly. He rolls over, realizes that their entire bed is kind of a wet spot now, between cum, sweat, and the amount of lube they used, and whatever wetness was coming out of Sanji, but decides he doesn’t care(He never really does, Sanji is always the one to demand clean up), and flops onto his back with a sigh.

“For real, though, I was thinking three kids, minimum.”

“Yeah, yeah, yeah, I get it. Three is your thing.” Hmm, seems like whatever daze Sanji was in was gone now. Oh well, great while it lasted.

Almost three months later, Sanji was struggling.

His pants...for some odd reason, wouldn't button. He had the tiniest bump on his stomach, but there was no way he had gained weight. Nothing had changed. He still ate the same, fought and trained just as much. So there was no reason he would have gained weight.

But he could feel it. He had a tiny bit of a stomach. Looked more like he was slightly bloated than anything else.

“What's taking so long? Luffy's already complaining that he's hungry.” Zoro huffed into the room, moments later, to see Sanji rolling around in his bunk, trying to button his pants. It was comical, and Zoro would have made fun of him for it if he didn't see how frustrated Sanji was.

“My pants don't fit.” He frowned.

“Really? Let me see.” Zoro strides over to him, tugging at his pants, arms straining as he tried to button them.

“Damn, maybe all of our lovemaking really did make you fat with a baby.”

WHACK.

“What the hell was that for?!” Zoro yelled at him, nursing the top of his head where Sanji had kicked him.

“You know that's not true, dumb-ass! Come on, be serious for once.”

“How can it not be true? We fuck every other day.” He shrugged, hands on Sanji's stomach. Gently rubbing the tiny bump that was there.

“Look? See? You did gain weight – HEY! I'm not saying it's a bad thing!” He had to defend himself before Sanji's kick came swooping down.

“There's no way I could gain weight. Nothing has changed in my regimen.”

“Except all the sex we've been having.”

“Zoro, shut up.”

“Alright, let's see what Chopper has to say?”

“Whhhhat?!” Sanji yelled, backing away from Chopper in disbelief. “No! No, it's not possible! This isn't some joke, Chopper, come on!”

“I would never joke when it comes to one of my patients, Sanji. You know me better then that. I know it's crazy, but you really are pregnant!”

“But...but how?!”

“Come on, Curly-brow, we-”

“I swear if you say one more thing, I'll kick your ass!”

“I...well I don't know! But whatever is keeping that baby inside of you seems...artificial?”

“How does it even make sense? What do you mean by artificial?”

“Could it be a devil fruit user, maybe?” Brook butted in, coming out of nowhere.

“Oh! Where'd you come from, Brook?” Chopper asked, turning to their crewmate.

“Get...get out, come on!” Sanji said. He really didn't need anyone else knowing about his...predicament.

“Seems like the only logical answer, honestly. There's a devil fruit for everything, really.” Robin added in. How did she get in so suddenly?

“Why are you here?! Come on, isn't this supposed to be private?”

“Nothing really stays private between this crew, you know that, Cook.”

“I...I just.” Sanji whimpered, sitting on the med bed, head buried in his hands. Sure, it was all fun and hot when he and Zoro pretended. But this was real now...He was really pregnant and really having a baby.

“We should talk to Luffy.” Zoro offered.

“Talk to me about what?”

“Why are you here now?!”

“I heard a lot of yelling and wanted to see what was up!”

“Sanji is pregnant!” Usopp added in. How did everyone get in without him noticing?

“Oh! Wow, really?! We get to have a baby on board soon? How cool! Can I be the uncle?”

“Oh! Me too! Super Uncle Franky has a great ring to it!”

“Luffy, no! It's not cool. Franky, it doesn't work like that!”

“Well why not? Don't you want a baby, and with Zoro? You two love each other, don't you?”

This was not a discussion he wanted to have right here, right now, with the whole crew. He and Zoro needed to figure everything out first. Like if they were even going to keep this baby.

“Luffy...we're all pirates. Wanted pirates. And none of us have achieved our dreams yet. How can we have a little baby on board?”

“We've had kids on here before, and they were always perfectly safe. Plus, how cute will a baby between you and Zoro be? I can't wait!” Oh great. Now Nami was here. Everyone knew now, like it was nothing. Like it was no big deal.

“Yeah, see! And we'll all help. It's not like you'll be alone.”

“Alright but...”

They had all decided to give Zoro and Sanji a separate room, a ways away from the guys dorm, so they had some privacy. Franky took no time at all to set it up. Excitingly exclaiming he'd build them a crib, too. While the girls were talking about how they'd go shopping for baby clothes on the next island (And more comfortable clothes for Sanji). Chopper had also told him to take it easy, and no fighting for the remainder of his pregnancy (27 more weeks to go!).

So now, Sanji was sitting alone, in their room, hand gently on the tiny bump that would continue to grow in the next few weeks.

“Hey,” Zoro's soft voice broke through his thoughts, and Sanji looked up just in time to see Zoro kneel in front of him, hands on top of his own, resting on the tiny bump.

“Hey,” Sanji greeted back, smiling sadly.

“Are you really okay with this?” He asked, pressing his forehead to Sanji's.

“I am. I just...didn't think all this talk would actually happen.”

“Hmm, yeah. Maybe I just have super sperm or something.” Zoro joked, trying to lighten the mood.

“Shut up, I can't stand you.”

“Well, you can stand me enough to have my baby, hmm?” Sanji couldn't help but blush. Zoro wanted this. The crew was beyond excited. Would it really be so bad? Making a little life between them? Did it really matter? Everyone was so happy, and deep down, he was happy too.

“Sure, maybe it won't be so bad. Daddy.” Sanji said, and Zoro's eyes widened, and a large smirk across his face.

Shit. Sanji didn't realize that would open up a whole other kind of kink.
