Welcome back, everyone! So, Arlong has been turned to fish food so I thought it'd be a good time to explore just how Luffy got started... Which, of course, includes a lot of hanky-panky!
Luffy's eyes cracked open to an unusual sight: nothing. There wasn't a girl next to him, snuggling into his muscled chest. Nor was there one cradling his back or lying on top of him. Most shocking of all, his cock was completely unattended. He honestly could not remember the last time he woke up without having multiple eager mouths tending to his penis.
He sat up, still in his concealed form, in what used to be the sole bedroom of Belle-Mere's house. He'd be dangling off every side in his base form so he concealed himself once he was done ramming every pussy he could find. Now, though, he stretched as he released his power and had to get off the full-size bed lest it be crushed under his weight.
It was only then that he looked and saw a paper attached to the back of the door. Peeling it off, he read,
"Good morning, Master,
We're sorry for not waking you up with your customary morning blowjob, but Nami had an excellent idea for a surprise to celebrate your newest conquest. Please wait for a bit, and one of us will fetch you once it is complete. Then you will get the ball-draining hours of sex you rightly deserve.
Love,
Sally Isntoinette"
Luffy chuckled at this, eager to see what his women had in mind. For now, he walked out of the bedroom. Just like last night, every piece of furniture had been moved as Luffy and his girls fucked the night away. He bent them over the dining table, laid them out on the sofa, and sat down in one of the two chairs while pounding away at the cervix of whoever was in his embrace. He also noticed that once again there wasn't a trace of cum on the walls or floor, considering how many nuts he busted out in the open for his girls to lap up.
By now, he just figured his cum also disinfected every surface he touched since actively licking walls would probably have made someone on his crew sick by now.
"Damn, another perk, these powers just keep getting better," he grinned before turning to the one piece of furniture that hadn't been moved; the armoire and its mirror. In its reflection, Luffy could truly admire what he had become. A ten-foot tall, massively muscular icon of masculinity with a cock that drooped past his knees even now and enormous balls bigger than his head that clapped against his thighs with every step.
"Man, I really have grown up," he said, teasingly flexing his biceps and pecs and relishing the raw power he could feel. He then released the mental restraint that kept his cock soft and watched it stretch until it almost touched the opposite wall.
"Hehehe, I love my Devil Fruit! Best thing that ever happened to me!" His cock shrunk back down on command, but this now made Luffy remember. Remember how, for the longest time, he thought he had the only dud Devil Fruit in the world. It only changed on his eighteenth birthday, when she appeared. Makino may have been the first member of Luffy's harem, but she was the one who introduced Luffy to a whole new world of pleasure…
Ten years. It had been more than ten years since Shanks left that treasure chest open at Makino's tavern, and Luffy, wanting to get back at the red-haired pirate for laughing at him, decided it would be a great idea to stuff the fruit in his mouth and swallow.
Then, after almost dying to the same jerk bandit and then a giant stupid eel that cost Shanks his arm, the pirate left after handing over his precious straw hat. Luffy had cried and swore that he'd make good on his promise to be King of the Pirates.
It was a shame, then, that that fruit hadn't done anything to him.
Garp, actually being helpful for a change, had tried everything to bring out Luffy's hidden power. Different training exercises, meditation, even special elixirs supposed to bring out your "hidden potential." None of them worked, and a few of those potions resulted in a nasty stomachache.
"Kid, I don't know what else to try," the Hero of the Marines said one day, the last time he'd ever visited Luffy, "I'm real sorry about that. I may not agree with you being a pirate, but nobody deserves getting screwed over like that."
His brother Ace wasn't much help, either. All he could do was try and comfort him, but that only went so far. And then Ace left two years ago on his pirate journey and found himself a Devil Fruit that let him be fire. Not just to create or control fire, but actively become it at will! It was so badass, and now he was a big shot with the Whitebeard Pirates.
Luffy still loved Ace, but he would admit he was super jealous of him. So he gets incredible powers, but all he gets is that he can't swim or touch some weird Seastone without going limp. Fucking great.
So now, here he was, on his birthday. His eighteenth birthday one year later than he was supposed to leave for his own pirate journey, just to see if maybe he could find a way to fix his broken Devil Fruit. Maybe if he just trained really, REALLY, hard he could find something! But nope. He did get stronger, but not much else.
But then, after Dadan did her yearly birthday tradition of actually cooking a meal for Luffy instead of making him get his own food, Luffy tucked in early that night. The other members of the Dadan Family soon followed.
Then, at 9:12 PM, Luffy was officially eighteen years old. An adult, according to the world. And, as it so happened, according to his very peculiar Devil Fruit.
Luffy soon found himself unable to sleep, a peculiar feeling between his legs. He sat up off his sleeping bag on the floor and trudged to the outhouse. And yet, when he got there and undid his pants, he noticed something weird. His penis was… standing up? That never happened before, and he knew better to wake Dadan or any of the bandits after dark.
Before he could dwell on that too much, a shriek cut through the quiet of Mount Columbo. It was a woman crying for help!
Whatever this was could wait, Luffy thought. He rushed through the forest, knowing the place like the back of his hand, until he noticed someone stuck up in a tree as a pair of massive tigers prowled along the base.
"Heeeeeeeeelp!"
"Hang on!" Luffy assured her, running full-tilt at the wildcats before smashing one away with a flying kick before punching the other square in the muzzle. Luffy may not have any Devil Fruit powers (that he knew of) but he was more than strong enough to stop these cats all on his own. He'd been hunting in these woods since he was a child, after all.
As soon the beasts scampered off, Luffy noticed the woman climbed down from the tree. He was surprised, given her short height and outfit made it clear she didn't mean to come here. She was dressed only in a sheer, white baby doll that left much of her cleavage exposed and her matching white heels. Her short blonde hair was curiously styled into two curlicues on the side of her head.
"Oh, thank you so much!" she said sweetly, "I didn't expect anyone to be out here!"
"Oh, don't mention it… What are you doing here, anyway?"
"Well, I was trying to get home to Goa but my friends all left without me and I guess I had too much to drink… Thank goodness you were here to help, mister!"
Luffy gulped as her round, bright blue eyes stared into his. He had the faintest idea she was lying but for some reason that weird feeling between his legs was making it hard to concentrate.
"Hm, it's only natural that I reward you for helping me. Now, what to do? I don't have any money… Oh, I know!"
The perky blonde stood up on her tiptoes and kissed Luffy's cheek. The boy practically felt his brain short-circuit as his face turned as red as the shirt he always wore. The girl just giggled as her hand, so soft compared to Luffy's calloused digits, wrapped around his and his confusion only grew.
"Uh, um, you don't have to… You know, I-I was just around and-"
"Oooh, and modest. I like that. Tell me, hero, what's your name?"
"Luffy…"
"Luffy? Well, Luffy, I think I haven't rewarded you enough. And I can see that you seem a bit uncomfortable?"
Her hand ghosted across the bulge in Luffy's pants, making the boy gasp. What the hell was going on with him?!
"Mmmm, big boy… Luffy, tell me, do you have a girlfriend?"
"N-N-No…"
"Good. Because she wouldn't like what I'm about to do…" The blonde slid smoothly down to her knees, deftly unbuttoning Luffy's jeans and wrapping her hand around the erect length now in her line of sight. Luffy gasped and had to hold himself in place as a sensation unlike anything else overtook his whole body.
"That's it, just relax… Let Catherine do all the work, hero. I'll make you feel sooooo good…" Her hand slid up and down the length of Luffy's dick, an appreciative seven inches and with the thickness of her middle three fingers curled together. He panted and grit his teeth, clearly unused to all the new feelings he was going through.
"Oh, you are just too cute," Catherine cooed, "How is a catch like you still single? Any woman would be so lucky to have you."
"Ca-Catherine… My… My god, it feels so good!"
"Oh, you think so? Hehehehe, you haven't felt anything yet!" Her hand pulled away, now fondling the walnut-sized balls between his legs. Before he could miss her handjob, her supple, pink-painted lips, wrapped around his cock and now the boy moaned out loud, not caring who would hear him. Catherine's little kiss had turned into his first blowjob, and now he completely at her mercy.
"Fuck… Fuck… Fuck…" he muttered under his breath, the only thing he could do as his brain was wracked with too many sensations. He could feel his hair standing on end, the roiling in his legs growing so intense it hurt, and something primal. Something in the back of his mind telling him how right this was, how much he loved this.
"That's it, enjoy yourself, Luffy," he heard Catherine speak into his mind, "A big, strong, handsome man like you deserves it! Do you like this, Luffy? Having a cute girl sucking your dick in the middle of the night?"
"Yes, I do! I love it!" he admitted, all his nervousness gone.
"Good, because I love it too. Your dick is so long, so thick… But I think you're capable of more. Come on, Luffy, cum! You can feel it, can't you? That tightness in your nuts? That's your body telling you it wants to spray your cum all over a pretty girl like me! Listen to that feeling, Luffy, and I know you'll do great things!"
"AAAAAAAAH! GONNA CUM! CATHERIIIIIIIINE!" he screamed before finally finding release. He relished every second of his first orgasm, spurts of white, creamy spunk splattering in Catherine's mouth that made her moan like a whore. He was so wrapped in this wonderful pleasure that he didn't notice a faint violent glow covering his body. He grow just the tiniest bit taller, maybe an inch, his muscles just a touch more pronounced and his cock was now seven-inches flaccid instead of hard while his nuts grew ever so rounder and fuller.
"Mmmmm, delicious… How did it feel, Luffy?"
"A-Amazing… I… Thank you…"
"Oh, you don't have to thank me, silly! I loved it too! In fact, I bet other girls would love to give you a big, wet, blowjob if you asked."
That thought made the same voice in the back of Luffy's mind very happy. He went down to hike up his pants only for Catherine to do it for him. "And remember, if you ever want that again, all you have to do is find me!"
As the last bits of sexual release left him, Luffy's mind began to clear and he just wondered how was he supposed to do that. He had no idea where Catherine lived! He was about to ask only to find the flirty blonde had disappeared.
"Catherine? Catherine?! Where'd you go?!" He looked around for a bit, not finding a trace of her. If he were thinking clearly, he would have wondered how a girl clearly dressed for a night on the town and was apparently defenseless against hungry predators could somehow move that fast, but he didn't. He was still coming down off of all these new feelings. And more than that, he felt great! All that tension was gone and now he cracked a giant yawn. He slunk back to the Dadan Family hideout and crawled back into his sleeping roll, before falling into the most content sleep he had in years.
The next morning, Luffy woke up with a new spring in his step and headed out for his usual morning. Catching breakfast was done thanks to those tigers from the night before, so after eating up he headed out for his usual run. A jog around the entire perimeter of Dawn Island was now just his warm-up but today something felt different. The whole run felt far easier than usual. It took a second lap to get the usual feeling of his legs being pumped which prompted him to stop in Foosha for a break.
Just as he was about to head into Makino's bar, however, he caught a familiar blonde hairdo. He turned and saw Catherine heading into a nearby house.
"Ooh, morning, Luffy!" she said with a wink, "You look like you could use a drink. Come on in, my door's always open for you!"
If Luffy had been thinking clearly, he might remember that Catherine was heading home in Goa Kingdom and therefore shouldn't be here but of course he wasn't. He was thinking with his other head, happily following Catherine into her small abode with his rod growing at the thought of a repeat of last night.
He entered the humble home, a small living room with pastel pink walls and lacey white furniture that matched Catherine to a tee. The woman herself was off in the kitchen, humming as what smelled like tea was being brewed. He simply kicked his feet up on the small ottoman in front of his chair and waited, now completely natural with having a raging boner.
When Catherine returned, she was quick to see the bulge in Luffy's pants, smirking as she returned with a tray in her hands. "Had a good workout this morning, did you?"
"Heh, not really. Actually, I was just warming up but something feels different."
"Oh? What's your normal workout look like?" Catherine poured two cups of tea from the porcelain kettle as she listened, and was frankly amazed. Apparently, Luffy's actual workout meant scaling Mount Columbo, beating up any predatory wildlife in his way, then scaling back down with a boulder strapped to his back. Then he'd practice his punches and kicks on the nearest trees, aiming to knock them down. He would then carry all the fallen timbers to Grey Terminal and break them into firewood with his bare hands before catching something for dinner on the way home.
"Wow… That kind of workout would break anyone else! What exactly are you going to do?"
A smile lit Luffy's face, his teacup now sitting beside him. "I'm going to be King of the Pirates!"
Catherine was amazed at the confidence in his voice. "Well, talk about having goals in life. But what are you still doing here, then?"
His smile faltered. "Well, I did something really stupid. I ate a Devil Fruit when I was a kid, but I never got any power from it. Got all the drawbacks, though. I sink like a rock if I even touch seawater."
"Hmmm, that does sound tough. But you know what I think?" Catherine stood from her seat before moving to Luffy's side, resting her chest on the armrest where Luffy could plainly see them.
"Maybe you just don't have the right motivation. Tell me, why do you want to be King of the Pirates?"
"Because being King of the Pirates means being the freest person alive, getting to do whatever you want and go on adventures all around the world!"
"Heh, that does sound like fun! You'd probably meet lots of different people doing that."
Luffy nodded, but his eyes kept drifting back to the two supple tits now resting just an inch away from his arm. Catherine just giggled, leaning in so her breasts engulfed his limb.
"And you'd definitely meet lots of pretty girls! I know I'd be impressed meeting to the King of the Pirates."
As she idly bobbed back and forth on her knees, Luffy had to hold back a moan with every meeting of her flesh on his. "C-Catherine, I…"
"Yes, Luffy? Do you like them?"
"H-Huh?!"
"My breasts, Luffy. Do you like them?"
"Y-Yeah…"
She just tittered at the embarrassed look on his face. "Good! Girls like it when you give them compliments."
"W-Well, uh, pretty sure Makino would say that's…"
"Inappropriate? Only if she isn't interest. That makes a girl uncomfortable. If she likes you, then you'll make her happy. And do you want to know what would make me happy, Luffy?"
He shook his head, leaving Catherine to stand up. She lightly pushed the ottoman aside so Luffy's feet were touching the floor. Now that he was sitting up straight, his eyes were glued as she turned around and pulled on the lacy string keeping her white baby-doll on her body.
"I want to make you feel even better than last night…" The cloth fell free from her hourglass figure, before slowly turning around so Luffy got his first look at her breasts bared just for him. A pair of bouncy, beautiful E-cups with nipples stiff from his presence.
"Ha…Ha…"
"Say it, Luffy. Say you want me. Be honest with yourself."
After gulping down the last of his anxiety, Luffy could feel that same feeling from last night in his head. How right this all felt, how much he needed this.
"Catherine, I want you. Right now."
"Hmhmhm… As you say…" She dropped to her knees, once again effortlessly revealing his erection. She appraised it for a moment, marveling at how it grown thicker and longer than last time, before grabbing ahold of the base. Luffy yelped in surprise only to moan at her luscious yet firm grip.
"Mmmm, what a stud… So, Luffy? What would you like? Want me to blow you again?" Her tongue just flicked across his lower head, making Luffy arch his back as he groaned.
"Or… Would you prefer this?" She hoisted her titties up before resting the top of Luffy's dick in her cleavage, making him hiss.
"That! Use your breasts, FUCK!"
"One tittyfuck, coming up!" With her goal in mind, Catherine sandwiched almost all of her new man's shaft in between the heavenly space between her mounds. She started with several slow movements up and down, getting him used to the feeling of paizuri. Once his moans became gradual, no longer shocked, she sped up her gyrations with only last few inches left unattended.
"Oooooh yeeeeah… This is the life…" Luffy moaned, feeling so damn good. He honestly was wondering why he'd never even thought of this before. He felt incredible, so much pleasure coursing through him. And when he looked down at the sweet, playful smirk in Catherine's eyes, it made him feel good that she felt good.
"That's it, enjoy it, Luffy. There's nothing wrong with sex. It makes you happy, it makes me happy, so why not? In fact… Why not bring more into it?"
"Hm? But isn't that cheating?"
"No, cheating is when you take a girl who's already taken and do it behind her partner's back. If everyone is open and honest about it, then it's totally okay!"
The more that mulled around in his head, the more he appreciated it. After all, he was planning on having a crew anyway. What was wrong with bringing a few girls along, so long as they could fight?
Any thoughts were gone once Catherine used her mouth to swallow those few exposed inches, making Luffy lose it almost instantly. Once again, every strand of cum sprayed directly into the blonde's mouth with a stream of moans in return. And once again, Luffy's body was wreathed in violet as he had a growth spurt. This time, though, Luffy could feel his body expand in the chair.
"Huh, that's weird…" he shrugged before standing up, now at six-foot-even with his muscles starting to chafe against his clothes. As he buttoned his pants back, Catherine redressed like she didn't just service a man in her living room before hooking her arm around his.
"So, what do you think, Captain?"
"You know, the idea's really grown on me… Thanks."
"Don't mention it! And if you ever want some more, just let yourself in and I'll be there!"
With that encouraging thought in mind, Luffy headed out and went back to his normal routine. He felt totally refreshed and ready to tackle the day!
In fact, the longer he went, the more he realized how easy all of it was. His normal exercises felt like nothing to him now! It was only after he managed to topple one of those trees in a single punch instead of several that he noticed how much bigger his arms were.
The rest of the day, Luffy pondered where all this strength was coming from before dragging himself back to the Dadan hideout. If anyone of them noticed their ward was literally growing taller by the day, none of them mentioned it.
Three and a half days now passed since his eighteenth birthday, and since these strange powers began to pop up. He couldn't make heads or tails of it, why would his Devil Fruit only activate now? It couldn't be because of how old he was, that didn't make any sense! He was almost tempted to call his grandpa but decided against it.
Now, as he tried to press on and find new ways to challenge his growing power, a new urge took hold. One far more annoying than just a hard-on. A tightness between his legs that made it harder and harder to concentrate until he was forced to sit from his attempt at five hundred one-finger push-ups.
"Goddamn, this sucks… Why do my balls feel like this?!" He was half-tempted to get to Catherine, but he was halfway across the island. He honestly wasn't sure what he would do if he had to hike all the way back to Foosha.
Before he could worry any further, a pleasant humming hit his ears. He turned and followed the sound until he approached a lake underneath a waterfall. Silhouetted against the curtain of water was an hourglass that made Luffy's dick stand at full-mast, now a foot long and his aching testes feel ready to burst.
"Hm? Who's there? Don't you know it's rude to peek?" a voice shouted over the rushing falls, but Luffy could easily make it out.
"Catherine?! What are you doing out here?!"
"Just washing up, the plumbing was out," she said casually before walking through the waterfall, revealing her completely naked body. Luffy's eyes all but popped out, desperately taking in every detail. Her bare breasts were one thing, but now he was drawn to between her legs. Luffy set his eyes on a vagina for the first time, the pink slit teasing him and making that voice from before scream in his head.
"Uh-huh… Seems a little extreme…"
"Aw, you're so caring! But don't you think there's a bigger problem here?" Catherine pointed down to the cock clearly outlined in Luffy's trousers.
As much as Luffy wanted to say yes, he was starting to get suspicious. First, she apparently lived in Goa, then she had a home in Foosha, and now she was comfortable bathing in the forest nowhere near either of those places?
The questions on his mind disappeared when Luffy felt her hands wrap around his waist, smushing those plump pillows on her chest against his. "Mmm, I can tell you've been working out. Your muscles are really something…"
"Heh, well, I don't know about that… I-URKH!" Her hands reached between his legs, feeling up his swollen nuts and cooing.
"Oh, you poor boy, you feel so pent-up! Did you miss me that much? All you had to do was call me…"
"I… Uh…"
"Well, let's see… I sucked your dick, then I gave you a tityfuck… I think I know what you want this time!" Catherine backed off and simply put her arms up against a nearby tree. Luffy was confused until he noticed her legs were just splayed enough to give a view of her tender pussy waiting for him.
Luffy stomped forward, his primal instincts going into overdrive. He honestly didn't know when he threw his clothes aside, only his beloved straw hat remaining on, before priming himself to lose his virginity.
Before he did that, though, he reached up and grabbed ahold of Catherine's breasts. The blonde squeaked in surprise before moaning as his hands eagerly explored this bouncy new territory, immediately becoming addicted to the sensation.
"When I'm done, you are going to give me some answers." His tone brokered no argument, and Catherine just thrust herself backwards to egg him on.
And with one thrust of his hips, the last boundary for Luffy finally broke as his dick was surrounded by hot, sopping cunny. Growls began escaping his lips as he thrust in and out of the blonde in his grasp.
"Ooooh, Luffy, YES! OOOOOOH, right there! Fuck, you're so good!" Catherine moaned, "I can-MMMMM! Feel how huge your-HAH! D-Dick is… So goodAAAAHH!"
But Luffy only barely heard her, too lost in his own world of carnal pleasure. At last, he finally saw the purple glow surrounding him and felt his energy return to him. That, however, could wait as far as he was concerned. He still had yet to cum, although Catherine certainly had. He could feel the hot juices squirting around his length, lubing him up before dripping down her delectable thighs.
"Catherine… Fuck, I'm…"
"Do it, Luffy! Do it right in my pussy! Bust a nut right in my womb, and let go!"
"GRAAAAAAAAGH!" And with that last resistance gone, Luffy's largest orgasm yet sent a torrent of piping hot cum right into the eager blonde, shrieking as she felt her own climax. Once she slumped to the ground, the last few spurts covering her folds and frosting her cheeks, Luffy felt a new wave of power overcome him.
When the energy faded, Luffy now stood at around six-and-a-half feet tall with the physique of an amateur bodybuilder. His vest's buttons were now strained over his pecs and abs while his shorts were forced around quads the size of an averages person's entire leg.
"What the…? What is this…?" he looked down at his hands before tensing his arm, watching in awe as his bicep engorged with power.
"Hah… Hah… Good, you're almost there…" Catherine panted, "One more ought to do it… Then you'll be ready…"
"Ready for what? You know exactly what's going on, don't you?! Well, spill it!"
"Luffy… Can you tell me the name of your Devil Fruit?"
He was about to snap that no, he never had a clue on what his fruit was supposed to be. That is, he would until the name just came to him in his head.
"Demon-Demon Fruit: Model – Incubus… What the hell, where did that come from?!"
"It's been with you… All this time, Luffy… You just needed to be an adult first… We're a lot of things, but interest in children… Isn't one of them…"
Luffy's eyes went wide. His eighteenth birthday. That's why it only activated now. He had gotten maybe the only Devil Fruit in existence that depended on the wielder's age.
"Wait, 'we?' What does that mean? Who are you, Catherine?!" He only then looked down to see the blonde was gone, again.
"Damn it! Oh well, at least I got something out of her this time… In the meantime, I guess I can finally look up what my powers are."
Luffy had never been one for reading. Being a pirate didn't usually mean you fancied libraries, but this time he made an exception. He went to Goa Kingdom, found the only library in Edge Town, and pored through whatever books he could find about what an incubus was.
It took quite a few tries, and one librarian getting very confused, but he finally found it. A book on the demons of the underworld. As soon as Luffy laid his eyes on the image of a ruggedly muscled demon-man, surrounded on all sides by adoring women, he knew he was in the right place.
Though his reading was slow, he took in every word. How incubi gained their power and influence by enthralling the hearts of women, how they grew in might the larger their entourage was, and how they were nigh-immortal unless you had very specific holy weapons.
Once he stepped out of Grey Terminal, Luffy had a lot to think about. He figured his fruit was one of those Zoans that let people transform into animals but Garp had never mentioned demons!
From there, he headed out into the forest and began testing his new abilities. To his delight, he discovered just how strong he was. The boulders and timbers that used to act as weights felt like paper to him! He could shatter stone with a punch and barely felt the impact. His legs were powerful enough to cleave a falling tree in half and jump hundreds of feet in a single bound.
And, after a bunch of punks decided to harass some people in Grey Terminal discovered, his muscles also made a strong defense. Normal people's blows couldn't penetrate his brawn, often resulting in bruised knuckles or broken toes.
But then the most shocking discovery came. Luffy, feeling something strange in his guts, focused on it and that purple energy from before appeared out of his hands. Firing it at a half-collapsed tree caused it to explode into wooden shrapnel. And that was from a blast the size of a cannonball! He could feel much more energy still stored within, promising even more destruction if released. He could also channel it into his hands and feet for even more devastating attacks.
After almost a full day of playing around with his new abilities, laughing off every predator that tried to attack him and dropping a truly gigantic pile of meat for the Dadan Family, he felt there was only thing left to do.
"Hey, Catherine! I need you!" he shouted from atop a cliff, then turned to find the blonde casually walking out from behind the trees.
"So, figured it all out, huh?" she said, licking her lips as she eyed his burgeoning body, "Gotta say, I am loving the new you."
"Thanks, so am I! Turns out my Devil Fruit is freaking awesome!"
"Oh, you definitely have something to do with it. I have friends who have seen men who got the fruit and barely changed. They bulk up a bit, get about three or four girls but don't do much beyond that. But you… Oh, I can see you having SO much more!"
She swung her hips as she approached, Luffy now shamelessly watching them bob from side to side as her breasts bounced inside her lacy top. "You see, this Devil Fruit draws on your own drive. The more you aspire to be, the more you grow and develop! And since you have the dream of being King of the Pirates, all that drive and willpower empowered you more than any man who's had this fruit before!"
That thought made Luffy feel a new sense of vindication. If it truly did stem from his will, and this was the result? He hadn't even left for his journey yet! He was already feeling on top of the world, ready to finally make his dream a reality!
"And look at this way! Now you can have a ship full of hot girls as your crew… or harem, whichever you prefer!"
Luffy would have scoffed at the idea last week. Now, it sounded perfect! Pirates were free, so as long as he and his ladies were happy so who cares what anyone else thought?
"Heh, how about both? Now hold still!"
"Ooh, bold, I like that!" Catherine just smiled as Luffy grabbed a hold of her baby-doll before ripping it right off her body. If she was bothered by her clothing being destroyed, then she didn't mind. Luffy, however, winced. He really didn't know his own strength at this point, plus he figured women wouldn't like having to constantly buy new outfits every time they did something raunchy.
He didn't feel too bad, though, once he got his hands on Catherine's chest again. Those soft breasts felt perfect in his hands, now easily able to cover the whole thing. He especially felt her nipples, erect from her own desire.
"You know, you still haven't told me who or what you are…"
"Mmmm… Y-You read up on your Devil Fruit, right? So, if you have the powers of an incubus, and I could tell, what would that make me?"
Luffy racked his brain, even as one of his hands snaked past her chest and gently caressed her stomach before stopping just above her moist folds.
"You're a succubus, aren't you? That explains you teleporting and how you knew what I was…"
"Good boy! Now stop teasing me and let me at that monster coooAAAAAAAAAGH!" With how much bigger Luffy's digits had gotten, his middle three fingers thrusting into her felt almost like a cock! She writhed and moaned, disbelieving that in a few days that awkward young man had turned into this BEAST!
"And his power still hasn't fully awakened yet!" she thought with glee before turning her head to the side she could ravage his mouth. Immediately their tongues clashed and smacked against each as they moaned together. She began grinding her ass into the now massive bulge in his pants, urging Luffy to whip it out already.
Not wanting to disappoint her, Luffy's shorts were thrown aside, and Catherine flinched at what swung onto her leg. She looked down and gaped at the enormous length he now had, it had to be almost a foot-and-a-half long and was as thick as her fist!
"Oh gods…! STICK IT IN MEEEEEEEE!"
"Sure thing!" With one shove, his head breached her folds again. He was worried it might not fit but that soon wasn't an issue. The deeper he pushed, the more her vagina yielded to his length to wrap every inch in bliss. Once his pelvis touched hers, he moaned before thrusting in and out.
"Yes! YES! YEEEEEEEEES! MOOOOOOOORE! YOU'RE MAKING ME LOSE MY MIND!"
"Fuck, you and me both! I love sex! I love fucking so much! Catherine, come with me! Join my crew!"
"OOOOOOOOH, L-Luffy, I'd love to… But…"
"Huh?! But what?! You need some more convincing?" His hands reached down, still plunging away, before hiking her up by her legs and folding her into a full-Nelson where his cock had even more power to slam away into the buxom blonde.
"AAAAAAAAAAH! OOOOOOOOOOH! LUFFYYYYYYYYYY! I CAAAAAAAAN'T! YOU'RE NOT READY!"
"Huh?! Not ready?! But my Devil Fruit finally works! I'm super strong, I finally have powers!"
"Y-Yes, but OOOOOOOH! T-They're not quite aWAAAAAAAAAAAAH! A-Awake yet…!"
Luffy's brow furrowed before doubling his pace, making Catherine completely incapable of speech. All she could do was babble and shriek as she cummed her brains out, but something in Luffy's brain told him she was right. There was one last push he needed to make before he could claim her.
"RAAAAAAAAAAGH!" A final shout escaped before a blast of cum filled her womb instantly, Catherine's toes curling before she was set back on the ground. She turned to see Luffy's body flare up with power one more time, this time completely obscuring him from view.
"You're… a fucking monster, Luffy… You'll do amazing things… In time… When you're ready for me… I'll come for you…"
She shakily stood up, semen still dripping down her thighs before she walked away and disappeared, leaving Luffy to absorb the full amount of his power. His body locked up before he was slowly surrounded by an ebony cocoon with the gleam of obsidian, left on that cliff for a full day. When twenty-four hours passed, the cocoon exploded in a flash of violet energy.
"Ugh, my head…" he moaned, feeling lightheaded before looking down, "Holy shit! I'm huge!"
He tensed his arms and watched as his biceps exploded to being almost the size of his head. As he walked, he could feel his balls smack against his legs and his even more monstrous dong sway with each step.
"Damn, she was right… This is my real power…" A massive smile lit up the island as he turned to the cliff and screamed, "GET READY, WORLD! I AM MONKEY D. LUFFY! I'LL BE KING OF THE PIRATES AND HAVE A MASSIVE HAREM AS MY CREW!"
From there, Luffy spent the rest of the day exploring the limits of his new might. Not just playing, but also making sure he could control it. He couldn't imagine hurting a girl because he got too rough during sex, after all. Once he was confident enough, then he strolled back to Goa and claimed Makino as his first crewmate.
And from there, Luffy felt his prick grow and throb as he remembered each and every pussy he plundered to get here. From a nobody on a small island to trouncing all of the biggest names in the East Blue in just a few months! Catherine was right, he did need time. But now…
The man turned and saw her, casually sitting on the bed admiring him. "Oh, don't stop on my account. I could stare at those mountains all day."
"Hehe, thanks! I've been working out!" Luffy brought both of his arms down in a massive crab flex, feeling his muscles groan and bulge as they expanded.
Catherine licked her lips as she openly fingered herself, making a certain incubus-man's cock grow to full-mast in seconds. Before she could mount him, though, the front door opened.
"Master!" Nami called, "Our surprise is ready!"
Luffy turned to follow her out, Catherine right behind him without any hesitation. As they traveled to what used to be Marine Branch 16, they passed through several villages where Luffy was met with cheers and adoration from the people living there. They were still in the midst of celebration from yesterday, drinking and dancing now that they no longer had the Arlong Pirates bearing down on them.
Once they arrived at the base, Luffy admired how they had repainted the place overnight to paint the Harem Pirates' logo over the original Navy emblem along with knocking off the mouse ears. Nami held open the double doors for him, only briefly holding Catherine up to get to know her. As far as the crew were concerned, any woman would want to follow her master!
But Luffy was more occupied at what had been done with the base. The sparse lobby was now covered in mattresses and pillows like one enormous bed, most likely stripped from the barracks. All of the various doors to rooms had been yanked off, with fully made beds being set up to make smaller nooks and crannies for love-making.
And assembled in this enormous nest were all of Luffy's lovers, down on their knees in reverence. "Welcome, Master!"
"Uh, what is all this?"
"This is your own personal love nest!" Asuka explained, "We understand your urges are strong and constant, so we thought you'd like a place you can go all-out during sex!"
"The barracks were all below ground in this base so we stripped most of the beds so you have plenty of space for fucking us!" Nojiko added. Luffy couldn't help but smile at just how thoughtful they were, planning all of this and no doubt fighting their own urge to be fucked every hour of the day to set all of this up.
But then his nose picked up his favorite smell: fresh pussy for him to claim. And then again, and again! The girls smiled as his erection grew before their eyes.
"There is one other surprise…" Belle-Mere chuckled, "There was one pretty rich family that sent all his brats off right before Arlong took over… The dad kicked the bucket a while ago, but we managed to find where his kids were hiding and told about the badass stud who kicked Arlong's ass would just love to meet them…!"
From the backmost hallway that led deeper into the base came a small parade of girls, all of them dressed in fine ballgowns that swished around their bare feet. It took Luffy a moment to realize that all five were the exact same height, had the same deep ocean-blue eyes, and possessed the same enticing E-cups.
"Oh yeah, did I mention that they were identical quintuplets?"
Luffy's cock bucked at the very thought. It was sexy enough to have a pair of twins with Lucy and Ashley in his harem but a set of quints?! He never knew he needed something so badly!
The rest of his harem parted to let the sisters through, lining themselves up at the front. On the far left was what he assumed was the eldest of the siblings, her hair a light pink and trimmed into a loose bowl cut. A single piercing in her left ear gleamed from the lights above. She winked at him when their eyes met, only making Luffy even harder.
To her left was the second oldest, her hair a more vibrant shade of pink and running down her back with a pair of blue and green ribbons tied behind either side of her head. Unlike the oldest, she was clearly trying to look angry with her cheeks puffed up and her eyes boring into Luffy with indignation. A pity for her that the puddle of fem-cum slowly forming underneath her gave her real intentions away.
In the middle was the only brunette of the group, her hair also long but much more loose than her immediate elder, shyly looking down and trying to ignore the fact that his twitching, pulsing phallus was covering her in shadow. To her right was an orangish blonde with a green ribbon tied around the back of her head and eagerly looking up, the only one unashamed of this whole situation.
To the far right was the youngest of the bunch, her hair wild and fiery red with one notable strand even sticking up. Her expression puzzled him the most. She was eyeing up his muscles, so hard that it was quite obvious that she was just staring at anything except his raging boner.
"Well, hello there!" he introduced himself, "So, you ladies want to join the Harem Pirates!"
"NO!" the pinkette with the ribbons yelled.
"Nino, please!" the brunette in the middle insisted, "We already talked it over…"
"Yeah, and I still think this is insane! At least Arlong wasn't a pervert!"
"Yeah, just horribly racist towards humans," the one on the left sighed, "I dunno know about all of you, but this guy looks way better! Don't you think so, Itsuki?"
The redhead on the opposite end tried shying her eyes away, but her hands subtly drifting towards the hem of her dress gave her away. The almost-blonde next to her chuckled.
"Girls, look on the bright side! He's super hot, super strong, and he's gotta to be nice to have this many ladies around!"
"Yotsuba…" Nino, apparently, rolled her eyes while the eldest rose from her knees.
"Luffy, is it? I am Ichika Nakano, current heiress to the Nakano Family. Our father was a Vice Admiral in the Marines, one of the only ones to come from the East Blue, and that of course meant we were all placed in the academy as soon as we could…"
"…Until we flunked out."
"MIKU!" Nino and Itsuki yelled at the middle sibling, who just shrugged.
"Yes, that's true. We just didn't have our father's grit or strength so we just ended up living there, doing chores to pass the time. They can't send us off without embarrassing themselves, until Miss Belle-Mere offered to personally 'whip us into shape.'"
Luffy grinned. "Well, whatever you girls can do, you all are welcome here! And trust me, there are a LOT of perks in it for you!"
The five listened as Luffy's other girls listed the many battles they won, the untold pleasure they received every day, and how they would never age a day and grow stronger and stronger along with their Master. By the end, all of them except for Nino seemed much more open to the idea. The stubborn one of the quints just refused to "lower herself" to this.
"Okay, you need a little convincing… So, who wants to volunteer?"
Yotsuba, Ichika and soon after Miku all stood leaving their sisters stunned before Luffy summoned a pair of clones to give them the individual service they deserved. Unlike other times, all three were simply picked up into a full-nelson lift in a line from oldest to youngest going left to right in full view of the other siblings.
"You two just watch! I'm gonna show you just how good being in my harem is! You three girls ready!"
"Yuh-huh!"
"Mmmm, yes!"
"P-Please be gentle!"
All at once, the three were dropped onto the pulsing cocks beneath them and orgasmed seconds later. Ichika's poise, Miku's shyness and Yotsuba's spunk were all replaced with matching, slutty O-faces as they were completely overwhelmed. With just a single thrust, all of them were completely taken by their new roles in life to milk giant loads of cum from their master every single day.
Itsuki and Nino tried to look anywhere else but the rest of the Harem Pirates were, as usual, getting into it themselves. With all the bedding on the floor, girls wasted no time throwing each other onto a mattress to furiously make out, ravenously eat out pussies, or grope and play with their absurdly large breasts and buttocks.
The sounds of slapping flesh, hungry moans and gushing juices acted as background music to the continued screams of the three Nakano girls being railed right in front of them. Behind them was the sole exception to this whole orgy: Catherine. The blond succubus lowered herself between the incredulous pair, her arms wrapping their shoulders.
"God, what a fucking monster… He's come so far in such short time… I've been fingering myself raw to him every night. What do you think, girls? Don't you want to feel good like your sisters?"
Haggard moans were the only response she got, until Catherine pulled them both closer. "Now watch, he's almost done. Then it'll be our turn…"
As they watched, all three Luffys' hips blurred as they pounded Ichika, Miku and Yotsuba to a delirious mess. The stream of femcum from them all reached their noses, combining with the debaucherous smells and sounds of his love nest to make his balls rumble in eager anticipation.
The very ground shook from the force of his combined ejaculation, rivers of cum rushing into the trio of Nakanos as they experienced an orgasm that forever redefined pleasure for them. As they were branded with his sigil, the three were flooded with even more sensations. They could feel the others getting their tits fondled, their asses spanked and their cunnies being ravaged all while Luffy still unloaded more piping hot semen.
The other Nakano girls couldn't believe what they were seeing, not a single drop of cum escaped from their snatches even as their stomachs began to bloat from the sheer volume. Then they watched their sisters transformed, growing several feet as their breasts and asses ballooned out, their hair grew longer and were pulled off their respective Luffy's cock.
"So, girls, what do you think?"
"Masterrrrr…" Ichika slurred, "Moooooore! I want your cock agaaaaaaaaain!"
Yotsuba and Miku didn't answer, too busy licking a shaft clean with the greatest devotion they've ever known.
"Well, they seem satisfied!" Catherine chuckled, "Still want to act all huffy now?"
"ME FIRST!" Nino screamed, literally ripping Ichika out of the rightmost Luffy's arms and tearing her own dress off, "GIMME! GIMME! GIMME! GIMME!"
"What am I, chopped liver?!" Itsuki yelled, taking the leftmost copy for herself. While Yotsuba was still sucking him off, she busied herself with hastily taking off her gown while Luffy sated her for now with a passionate make-out session.
That left the central one, the original Luffy, his hands on his hips as the middle Nakano, now another sexy, stacked brunette for his harem, slavishly sucked his cock. Catherine approached him from behind, her hands reaching down to feel his balls churn and buck as they refilled cum by the second.
He turned and finally saw Catherine's true form. Her skin was an icy blue with black, winding runes all over her arms and legs. Her eyes were a deep blood red and a pair of chitinous horns now poked through the crown of her head, along with a forked tail swishing above her plump rear.
"Fuck me…" she whispered in his ear, "Fuck me senseless. You're more than ready now. Make me yours, Master Luffy…"
With a simple pat on the head, Miku slunk back to get to know the rest of her new sisterhood. The blonde, already naked and dripping wet, laid on her knees and hands and simply beckoned Luffy to take her. With each stomp towards her, her loins grew warmer until his length slapped down on top of her slit.
"You're the one who started my journey to become the king of my personal harem. Now, it's finally time for you to join."
"Mmmm, yes! Go on, Luffy! Stick it inAAAAAAAAAAAAAAAH!"
Nino and Itsuki didn't have to wait long after Catherine, both being taken in the same mating press as their sisters. With another round of pussy poundings, the Harem Pirates wasted no time getting their newest members involved.
"Mmm, fuck!" Ichika moaned as Homura and Zora fondled her new breasts, almost double the size of her head, and sucked on her nipples while helping herself to fingering their pussies.
"MMMM! MMMRE!"
"Oh, she's just too cute!" Ririka cooed as she, Dadan and Olive all laid their focus on Miku, the meek brunette only being able to wright as the former restauranteur wrestled her tongues while the other two double-teamed her pussy.
Yotsuba, meanwhile, was swept up in another of Yagyu and Hibari's love sessions alongside Sanju. The eyepatch-wearing girl was behind the blonde Nakano, eating her out while Hibari was beneath her eating out her longtime lover. As for the chef, she was alternating between Yotsuba's nipples, indulging her own perversions.
"Hehehehe, titties! More and more titties for everyone!"
"Oh dear, my little sister really is incorrigible…" Reiju sighed before shoving four fingers into Carina's pussy, eliciting another orgasm while she stuck out her tongue to catch the droplets of juices squirting out.
"AAAAAAAAAAAAAH!"
"OOOOOOOOOOH!"
"YEEEEEEEEES!"
"Fuck me, so tight! All of you, my personal harem of fifty! And I hope you girls are ready…"
It was time once again. Luffy's body was surrounded by a violet glow that began to be spread to all his girls old and new. The three currently impaled on his shaft were no exception, feeling the demonic energy overtake them for the first time but more concerned with their cunnies being shaped to his cock.
With a final shout, all three Luffys orgasmed and released another torrent of cum just before the transformation took hold. The clones disappeared, leaving Itsuki and Nino with the aftershocks as they watched their new master grow even more powerful.
When the energy cleared, Luffy now stood at twelve feet with his muscles growing even more pronounced and his cock becoming even longer, thicker and for once nobody was paying attention to that.
All of the girls felt something very different about this latest glow-up. Sure, they grew taller, their assets even more bouncy and sensitive and they felt stronger but they also felt something deeper in their guts. The only exception was Catherine, chuckling as she quickly got used to her more extreme hourglass figure.
"This is why I had to wait," Catherine explained, "As a succubus, I drain men of their energy to refuel my power. But now that you're strong enough, you've claimed me and added my power to your own instead…"
Luffy watched with wide eyes as his girls were covered by their own energy veils before revealing themselves. Their skin changed to stark white to fiery red with their own swirls of black. Horns on their head, tails fretting behind them, and a palpable sense of might between them.
"…And now your fruit has granted them all my power. Congratulations, Master Luffy! You now have a crew full of succubi!"
Luffy could scarcely believe what he was seeing, or feeling how much his own power had grown as a result. That changed only when several of this ladies crowded around him, lavishing his expansive bodies with kisses and licks as they begged him to use their bodies to soothe his even-larger erection.
"You know, the actual amount of incubi who've done this? I can count them on one hand!"
"Heh, guess I better make the most of it…" Luffy grabbed Catherine by her tail, yanking her backwards and resting on top of his cock like it was a pommel horse, "…And make my harem even bigger! Come on, ladies, let's put this love nest to good use!"
"YES, MASTER! WE LOVE YOU, MASTER!"
So, yeah, that just happened! Luffy's halfway to a hundred ladies, and now all of them have demonic powers! We'll get into the specifics of that later, but rest assured they can shift into a restrained form, their hyper-bombshell form and their demon form like Luffy can.
Speaking of which, you may have noticed that despite getting another power-up Luffy didn't show off any new abilities. That's because I'm torn between two ideas and decided to see what you all would prefer! In short, here are the options:
1. Luffy and his girls can effectively shapeshift, which has many practical applications like disguising themselves from Marines but also means the girls can summon any sexy outfit they want without breaking the budget!
2. Luffy has the power to effectively control his domain. He could repair or alter any island or ship he claims, whether that included rebuilding the destroyed villages on Conomi Islands or turning any indoor space to be much larger on the inside.
Whatever option is not chosen will be saved for when Luffy hits 100 ladies, so it'll be a ways away. In the meantime, Luffy will be making his way to Loguetown!
