Hi guys Azza here!

Ok so first bit of warning there is a lemon at the end of this chapter and it's a bit out there, definitely way different than what I've written before so just a heads up on that.

Onto the reviews.

Dragonborn2704 – Oppenheimer … honestly he would actually make a great Servant I admit I hadn't actually considered him in the slightest. His historical importance and very noteworthy quotes definitely would qualify him as one I'd say I'll definitely see if I can include him though I've got a fairly good idea how I would already.

Le Phoque Blanc – I mean when you have multiple Yonkou level Servants plus Natsu all battling it out alongside countless other Admirals, Warlords and Yonkou Commander level characters I'd say kicking the hornets nest was a rather fitting euphemism. As for the core plot of Marineford I'm hesitant to change that because honestly its some of the finest work Oda has ever done so it will be more about vastly higher stakes and characters such as Whitebeard being even more powerful than in canon.

Anyway enough from me, on with the story!

I do not own Fairy Tail, One Piece or the Nasuverse.

Welcome To Sabaody Archipelago

/Natsu's POV/

"You said this is the main part of Sabaody," Natsu asked as the ship slowly pulled up alongside a dock, the anchor dropping moments later. "I thought it'd be larger?"

"A lot of people get that impression from people who tell of it," Hachi replied as the entire crew began to disembark. "Honestly I wish the place was bigger than it actually is …"

"Why's that," Luffy asked curiously as Hachi paused mid-step, crossing his six tentacle arms as he looked down at the Straw Hat.

"Listen, before we go any further there's something all of you need to hear," Hachi said seriously though his eyes never once left Luffy's own. "This isn't something silly either, it could affect if all of you live or die."

That instantly had Natsu's attention, his senses immediately expanding to cover the entire island they were on as they scanned for any remote sign of hostility. Unfortunately, the shroud that had blocked him earlier appeared to have only grown stronger, blocking him from certain sections of the island.

"This island is a place where slavers … sell their product," Hachi said bitterly, finally looking away from Luffy as a sneer worked its way onto his face. "My kind are the most common however humans and other species also often end up there."

"So, there's a slave trade operating out of this island is there," Natsu growled as his senses isolated the areas he couldn't get into, a feeling of rage slowly building up within him as he considered just what could actually be so bad he couldn't push through with his senses.

"Yes."

"And the World Government just allows this to operate," Sanji asked curiously, no less disgusted as everyone else as Hachi nodded grimly.

"They not only know about it, but actively support it," Hachi replied as several cries of outrage were heard among the group. "But there is a bigger reason as to why they are able to enforce it …"

"There's no valid reason for enslaving a sentient being, regardless of race," Natsu snapped as Hachi held up his hands.

"I-I know that Natsu, but this is probably the only possible reason the World Government would allow it," Hachi stuttered out as the heat rose by several degrees. "Its because of the Celestial Dragons!"

Natsu froze at the mention of that particular name, the Celestial Dragons. His mind flashed back to Water Seven and his conversation with the Golden King Gilgamesh, the man's own rage at them now making much more sense.

/Flashback/

"I had planned my advance on their main headquarters when word came through about a veritable Holy Land resting atop the tallest mountains in this world and since everything that holds value is mine, I naturally sought it out."

"I'm guessing you met these Celestial Dragons I've heard reside there then?"

Natsu was surprised at the sneer of disgust that appeared on the King's face at the mere mention of their name.

"Those false Gods," Gilgamesh spat. "As I arrived at the front entrance the guards dared to turn me away stating that I was nothing compared to their Divine selves ... ME!"

"You didn't ..."

"I did. I slaughtered the guards at the front entrance and forced my way into this ... Holy Land that the world itself reveres like The Root itself and what do I find ...?"

"The Celestial Dragons?"

"Mongrels, an infestation of lazy, selfish, unmotivated dirty mongrels," Gilgamesh spat as he seemed to look off to his right deep in thought. "One dared to raise a firearm at me demanding I be his slave ..."

"You-!?"

"I slaughtered the mongrel where he stood, his mouth hitting the floor before he ever finished such an unfathomably ludicrous statement."

"I doubt that went down well?"

"It did not. This was when I learnt of the new branch of the armed forces created by the World Government and led exclusively by Servants, not that they could truly stop me anyway."

/Flashback End/

"The Celestial Dragons come to this island to purchase slaves," Natsu hissed as he heard the low growling sound coming from Aava's throat.

"Gilgamesh said they acted as if they were true Gods, demanding that he become their slave," Ahnk chimed is as he too replayed the memory in his mind. "I assume we'll be dismantling this slave operation?"

"Obviously."

"Wait a minute Dad, Hachi is still talking," Aava cut in as his attention returned to the conversation at hand.

"So, the Celestial Dragons frequently come to this island," Robin shuddered as Natsu saw the various reactions of the crew.

The only ones who weren't showing any outward sign of fear were Seilah, Mordred, Luffy and naturally himself. Everyone else showed some modicum of fear at the mere mention of a Celestial Dragon being present and he knew there was something off.

"So, what exactly is it you're trying to say Hachi?"

"What I'm trying to say is I know how you guys operate," Hachi snapped back, shocking everyone as the Octopus Fishman lost his composure. "I know how you all can't help but pick fights wherever you go!"

"So, what exactly is the punishment for … let's say attacking one of these Celestial Dragons," Natsu asked curiously only for the Fishman to wrap all six arms around him, throttling him as he eyed the man in shock.

"Don't you dare even consider such a thing! Never under any circumstances ever do anything to impede them, don't even breathe near them!"

It took some effort but he managed to pry the Fishman off of him without harming him, watching as Hachi panted heavily through what was obviously the early signs of a panic attack.

"What are the consequences of doing anything to them?"

"The consequences are really bad," Camie replied shakily as all eyes turned toward her. "Just for annoying one of them they can have the World Government deploy an entire army led by either one of the Admirals or Generals …"

"Plus, if they really get mad, they'll have the island destroyed by a Buster Call just for good measure," Hachi added as Natsu noticed the faint twitch in Robin's body at the word. "But those two are better fates than what they'll do if you're actually caught by them …"

"Caught?"

"If a Celestial Dragon looks at you and says that you're now their slave then that's just how it is," Hachi replied fearfully as a look of complete disgust washed over both Natsu and Mordred. "No one challenges them because they can kill us all with but a single word!"

"And that trash rules over this world," Mordred growled, her body beginning to shake as her thoughts returned to that of her own life. "Scum that hold no value over the lives of their subjects … who use their power to destroy their own realm-!"

"Mordred."

Placing his hand atop Mordred's head he gently ran a hand through her hair as the rest of the group, Seilah included, watched the outburst in confusion. Seeing that the group wanted an explanation he looked to Mordred who nodded slightly, not deigning to look back at them however which meant he would be the one to relay the full story.

"You all might be a bit confused as to why Mordred despises people such as what Hachi described the Celestial Dragons, correct?"

"Well that's one way of putting it," Nami replied bluntly.

"I could feel a spike in her emotions, Mordred hasn't felt such rage since we first met and she spoke of her Father."

"Of course she hasn't Seilah," Natsu sighed as he moved his hand to better massage her scalp. "Mordred might have hated her Father however her Father was also what most would consider to be the embodiment of a true King, one who could usher in the fabled 'Utopia' so many mortals have fought and died for."

"So, Mordred is pissed because she knows how a real ruler should treat their subjects, that seems fair," Usopp remarked prompting Natsu to shake his head.

"Then what is it," Sanji asked as Natsu removed his hand and fully turned to face them.

"Whilst Mordred's Father was the ideal King in almost every regard, her Mother was not. It was she who destroyed the kingdom her Father had worked tirelessly to create all in a selfish attempt at taking the throne for her own."

"Regicide," Robin muttered. "How bad was it?"

"You guys all remember how Crocodile tried to overthrow the Nefertari Dynasty in Alabasta and take it for his own," Natsu asked as most of the group who had been present nodded. "The fall of Arthurian Britain makes what would've been the result of that look like a mere case of a thief at market."

"W-what!? But how could such a thing be possible," Nami gasped. "Alabasta was huge!"

"Surely you're exaggerating," Zoro asked as he finally gave his two cents. "I don't doubt it was bad but how bad could it have actually have been?"

"Mordred is my Servant and as such we experience each other's lives through dreams," Natsu explained as the group's eyes slowly widened. "I have seen first hand the fall of Arthurian Britain and I can say with certainty that it was an event that changed the course of history, not just for mortal kind but all beings great and small on a planet wide scale."

"Y-you're joking, right," Usopp chuckled shakily as Natsu's rather blank look settled upon him. "You aren't … are you?"

"Mordred's Mother used everything to try and take what was one of the most coveted thrones in all of history, tossing aside millions upon millions of lives and decimating a once Utopian society down into the equivalent of Tartarus on Earth. But what enrages Mordred more than anything else is her own role within this great betrayal, the role placed upon her before she had ever been conceived …"

"What happened?"

"Mordred-."

"I was the one who struck down my own Father," Mordred cut in as she turned to face the group with a scowl, her eyes scanning the shocked faces of each and every last person present. "Not only that but it was I who incited the rebellion against Father's reign, shattering the Knights Of The Round Table and slaughtering those I had once sworn to protect."

"So, when you say you're a 'Fourth Rate Knight' all the time, what you're actually saying is-!"

"That I, Mordred, am the epitome of a traitor," Mordred replied as she met Luffy's shocked gaze. "I destroyed the greatest kingdom to ever exist, one where all races, ideology's and peoples could coexist peacefully all because my Mother told me to."

"Not completely willingly, of course," Natsu cut in as Mordred's eyes flicked to his own, a slight sheen to them as he placed a hand on her shoulder. "What Mordred fails to mention is that her Mother was one of the most powerful Mages to ever live and manipulated her into doing it. Mordred had actually been killed by her Father however it was her Mother's power that ultimately slew the King using her body as a medium."

"What kind of monster would go that far to become a King," Luffy asked in shock as Natsu's own face contorted into a scowl.

"The same trash that these Celestial Dragons are made out of," he hissed in reply. "If any of you encounter these Celestial Dragons NEVER look at them as if they are human! Sure, they'll preach to you that they are supposedly 'Gods' but that couldn't be further from the truth …"

"They're sub-human," Mordred spat as a look of determination crossed her features. "Little better than feral beasts, good for nothing but death!"

"Nyuu … You shouldn't say that so loud," Hachi replied shakily. "What if someone hears you and-?"

"Fuck them," Mordred snapped back as Hachi visibly flinched whilst looking around fearfully. "Look at you, and even some of you lot," she snapped as some of the Straw Hats who had grown up knowing of the Celestial Dragons flinched. "Pissing yourselves over such scum-!"

"Mordred!"

Mordred's rant was cut short as a much firmer hand was placed upon her shoulder, the hand of her current Master. She knew he actually fully supported her anger however it quickly occurred to her that those who were fearful before her did not cower out of desire, loyalty nor respect.

It was out of fear.

"Sorry …"

"For now," Natsu sighed as his gaze shifted back to the group. "I would say lets all heed Hachi's advice and lay low. Sure, we could just kick the shit out of anyone that came our way but if it means an entire island could be put at risk …"

"Best to not do anything unless its drastic," Robin finished for him as he shot her an appreciative smile.

"Precisely."

"So, if we're gonna try and avoid getting into any trouble here then we should go find your friend then, right Miss Camie," Sanji asked as Camie shook away the shock of everything she'd just heard and nodded stiffly.

"Y-yes … In order to reach Fishman Island, the next island on your Log Pose, you'll need to get your ship specially coated so it can go underwater."

"So, you were serious about that," Natsu mused as the mood slowly began to shift from its currently depressive state. "How exactly does one use a coating to make a ship made of wood a submersible?"

"Oh, you don't know Mister Natsu," Camie replied in genuine surprise.

"Should I?"

"Well, you seem to be really really smart so …"

Natsu simply chuckled as Camie blushed from embarrassment, prompting many of the others to chuckle in response.

"Trust me Camie I'm not all knowing, likely never will be either. I'm just a lot older than I look so I've got the experience that goes along with that."

"You guys just have to come with us to see our friend," Hachi said, taking some of the attention away from the still blushing mermaid. "I'm sure once he hears about how you all helped me, he'll coat your ship for free."

"Did someone say free," Nami asked, her eyes having converted into Berry signs as the rest of the group shook their heads.

"We need to get to Grove Thirteen, that's where the ship coater lives," Hachi said, easily ignoring Nami's money comment. "But again just remember that Celestial Dragons could be anywhere on this island so even if you see someone die right in front of you, don't do anything!"

"We got it the first time," Natsu replied with a wave of his hand. "Anyway, you guys can go on ahead without me for a bit."

"Where are you going," Luffy asked only to see his hand hadn't left Mordred's shoulder. "Ah …"

"I'm thinking I might stay on the ship with Robin," Seilah said as she turned toward her fellow Demoness. "I want to continue our lessons on controlling Etherious with her."

"I'm also gonna stay here with Usopp," Franky added with a grin. "You know, general ship maintenance and all that!"

"I'm thinking I'll head out with you guys and see if I can't find a shopping district to stock up on food," Sanji said to Hachi who nodded quickly.

"We'll be passing by the shopping districts on the way to Grove Thirteen."

"Guess I'll go and do some scouting," Zoro said as he began walking away only for Sanji to grab him by the back of the shirt.

"Don't even think about it Moss! You'll only get lost and start trouble, trouble we can't afford!"

"And you'll probably go and grope some poor girl, virgin cook."

"THE HELL DID YOU JUST SAY-!"

"SHUT UP," Nami screeched as she hit both of them over the back of the head with her Clima-Tact. "No fighting!"

"Tch, whatever! Look, I'm just gonna go and find the nearest bar," Zoro huffed as he began to walk off into the forest. "Can't be that hard to get around this place, just follow the big ass numbers on the trees …"

"Well, guess we're all splitting up then," Natsu said with a slight grin. "Like Nami said guys, no fighting and definitely no starting shit with any Celestial Dragons! I'll come find you guys in Grove Thirteen later, alright?"

The group nodded as Natsu and Mordred vanished from view, no doubt popping up somewhere else on the island as the rest of the crew slowly split up.

/Meanwhile – Grove 10/

"You know, for a single island this place sure is huge," Ritsuka remarked as both he and Mash perused the various shops. "How many Groves have we gone through?"

"Nine I believe, Senpai."

Ritsuka sighed and took a seat on a nearby bench with Mash taking a seat beside him moments later. Looking over at her Master she could tell he wasn't tired but rather he simply had no clue on where the duo should even begin.

Normally, the duo would have had guidance from Romani, Da Vinci and Natsu however due to the unique nature of this Singularity they weren't able to rely on regular methods of communication. As a result they were, for all intents and purposes, walking blindly.

"You don't think Natsu put something that'll give us a waypoint in one of those things he gave you, do you Mash?"

"I don't believe so," Mash replied with a shake of her head. "He gave me things he considered to be essentials and some other small things, nothing that would give us any solid leads as to where to begin our investigation."

"You'd think that with this being his own past he'd know what we should do," Ritsuka sighed only for Mash to swat him over the head. "OUCH!"

Looking over at Mash he was surprised to see her now towering over him, hands on hips with a fearsome glare that would obviously defeat even the mightiest of foes. Or at least he assumed she thought as such, in reality it was rather adorable.

"Senpai! Director Natsu has done all he can to make sure we have as much available to us as possible without further disrupting the timeline! Doing what he has already done for us is no doubt pushing the limits of how far he can interfere, we should be very grateful!"

"Ok, ok," Ritsuka replied quickly as he raised his hands in surrender. "I know he's doing his best I was just venting a little!"

"I understand that Senpai but insulting Natsu when he went through all the trouble to develop those other Mystic Codes for you isn't fair," Mash replied with a softened gaze as Ritsuka took a moment to examine part of his Pirate getup.

"I know Mash its just, we barely survived London and he throws us right into the deep end like this …"

Mash grimaced as both of them thought back to the most recent Singularity they'd been forced to deal with. Okeanos was one thing but the foe they ended up facing within that was far worse than any they'd likely be facing again anytime soon.

They both drew what little comfort they could from that.

"Oh!"

"What is it," Ritsuka asked as Mash placed her shield down and opened up a small compartment, drawing from it several small capsules. "What are those?"

"Natsu gave them to me before we left and asked me to use them when we had a spare moment. Perhaps now would be a good time to use them?"

"Maybe," Ritsuka said thoughtfully as his eyes scanned the area. "But not here, that's for sure."

Mash quickly understood what he meant as she noticed several eyes watching them curiously, some eyes on her specifically with what she could immediately tell were … less than savoury intentions.

"Right …"

The pair began to move toward the next Grove and noticed that the same people who had been eyeing them also began to move. The two shared a look and moved at a quicker pace toward the forest, their pursuers now running to catch up with them.

Once they had left the purported safety of the Grove dozens of men appeared from the tree line, forcing the pair to skid to a stop as their pursuers quickly closed off any means of returning the way they came.

Quite the pair of legs on you kids, 'specially the girl there," one of the leaders grinned as he licked his lips. "Unfortunately for the two of you, we're not just here to shout your praises."

Many of the others surrounding them laughed as several of them began to slowly advance toward their position, the sound of rattling chains becoming evident as both teens eyes widened considerably.

"Now, we can do this the easy way … or the hard way?"

"And please," another man grinned as he drew his sword. "Please do try the hard way first …"

"Senpai …"

"There's a lot of them," Ritsuka muttered as the circle drew tighter around them. "But you know what they're gonna try and do to us, right?"

"Yes," Mash muttered in reply as Ritsuka shifted his stance.

"I'll give you guys one chance to let us go peacefully, otherwise what happens afterward is on you!"

The men stopped, looked between one another, and laughed.

"You hear that boys!? The brat thinks he's some sort of hotshot!"

"We're gonna take extra special care of that lady friend of yours, boy," one of the men chuckled darkly as they all began drawing their weapons. "We'll tie you up though in a nice spot so you can watch as-!"

The man ceased his threat as blood began to pour from his mouth, the other would be slavers looking behind the man in shock. All Mash and Ritsuka could see was the end of a blade protruding from the slavers chest and were shocked when it was yanked free to reveal a man with short green hair.

"You two alright," the man asked as he casually strolled right into the centre of the group and stood next to them. "These guys doing what I think they're doing?"

"They're slavers," Ritsuka replied hesitantly. "Who are you?"

"Roronoa Zoro, just call me Zoro," the swordsman replied as he drew a second blade. "Now I heard you two warn these guys so I'm guessing you could've probably fought them off but I'm not one to let slavers kidnap people right in front of me so you'll have to accept my apology for jumping in after we've taken out this trash."

"R-right," Ritsuka replied as he turned toward Mash. "You ready?"

"Beginning combat operations, Master," Mash shouted much to the surprise of Zoro as she summoned a shield much larger than herself, prompting all the slavers to take a step back.

"Shit!"

"She's a Servant!"

"Settle down boys," the lead slaver snapped as they all pointed their weapons at Mash. "You all know the price for a legit Servant!"

The slavers seemed ready to fight after the mere mention of how much Mash would be worth captured as Zoro placed a third blade into his mouth.

"As much as I wanna ask why a Master and Servant are getting harassed by slavers I reckon it can wait until after we've taken out these guys," Zoro said as Mash slammed her shield down next to her, cracking the ground as she glared at the slavers who had been eyeing her earlier.

"Agreed."

What followed was a completely one-sided massacre as Zoro and Mash brutally slaughtered the slavers whilst Ritsuka looted from their still warm corpses anything of use.

/Elsewhere – Natsu And Mordred's POV/

"I'm sorry," Mordred sighed as she sat down on a box, the pair having appeared in a rather small alley on the outskirts of Sabaody. "I thought I was past all that, being pissed about my family …"

"I don't really get why you're apologizing Mordred? Sure, you got shitty but let's be real for a second and acknowledge that these Celestial Dragons are sub-human filth, trash who have no right to rule even their own home let alone the world."

"Hearing that Hachi guy speak about how terrified he was of them, how people fear to even speak their names and can be executed and enslaved on a whim …"

"I get it," Natsu sighed as he crouched down before her. "You know they are the furthest thing from what a ruler should be like and it angers you the way they treat their subjects."

"They aren't rulers," Mordred spat as she grabbed onto Natsu's collar and pulled him forward so that their eyes met. "They are tyrants!"

"Agreed."

"And if we come across any of them," Mordred added, her gaze never faltering for a moment as her grip loosened slightly. "We kill them. No exceptions."

"Knowing the consequences?"

"What are consequences to my Master who could nuke a continent with his power if he didn't hold back?"

"Touché."

"Well?"

"Well what?"

"What do you think of that?"

"About you executing any Celestial Dragons we come across?"

"Yeah."

"Unfortunately, I'm going to have to forbid you from exacting your own crusade against them," Natsu replied as Mordred's eyes shifted through so many forms of confusion, shock, hurt and betrayal until he suddenly gripped her by the hair and held her in place.

"Wh-what," Mordred gasped as he leant in closer, a sadistic smirk crossing his own features as he whispered gently into her right ear.

"I'll have to decline because your version of punishment, whilst no doubt efficient, will be … lacking and will no doubt fail to strike fear into them compared to what I've got in mind."

Pulling back he fully released Mordred who clearly needed several moments to reboot. His smirk was wiped off of his face however when Mordred rose from her place and kicked him in the chest, knocking him against the wall behind him as she quickly moved to straddle him.

"Mordred, what-!?"

He was silenced when Mordred rather forcefully captured his lips with her own, her right hand placed against the back of his head as she gripped his wild hair tightly. Nipping at his lip hard enough to draw blood she quickly ceased the kiss and licked the wound twice before licking her own lips, a burning desire now beholden within her emerald coloured orbs.

"Mordred …"

"I swear if you were around during my time I'd have made you mine," she whispered huskily as Natsu's hand quickly slid up her shirt, moving to squeeze her breasts. "You've been holding back since Thriller Bark and the two of us haven't done it since even before then …"

"I was holding back because of-!"

"I don't care," Mordred growled as she nipped at his neck, grinding herself against his now raging erection. "Fuck whatever shit reason you had because I'm getting what I want right now!"

"Fine," Natsu chuckled as he applied pressure to her left nipple, eliciting a growl of approval. "I'll just get us back to our room on the ship and-."

"Fuck that, we'll do it here," Mordred replied with a slight growl to her tone as she pulled off her jacket and tossed it onto the box behind her before pulling off her shirt, slightly ripping it in the process before also tossing that to join her jacket.

"Shit Mordred …"

"You know how I get whenever you act slightly psychotic," Mordred replied with a sinister smirk. "I don't know how I'll keep myself together if we're both there to torture these Celestial Dragons …"

"One would wonder just how sane you truly are, Mordred," Natsu replied before taking her right nipple into his mouth whilst still applying pressure to the left. "But then again …"

With a practiced motion he'd torn away Mordred's jeans, ripping them to shreds, as his Servant began to laugh.

"I knew you couldn't hold back forever, though you owe me some new ones now."

"Whatever," Natsu growled as he allowed his own clothes to fade away, leaving the pair naked in the dingy alley. "Offering to fuck me in this grimy alley like some sort of whore, you've earned every last bit of this."

"Is that what I am," Mordred laughed as Natsu stood up, taking Mordred with him as he spun around and forced her up against the wall. "Just some kind of dirty whore for you to take out your frustrations on?"

"Of course you are," came the lustful reply as his middle finger entered her dripping sex. "You're nothing but a fourth-rate whore!"

Mordred moaned as he pulled on her hair with his free hand, her own finding his rock-hard cock as she began to stroke it roughly. It was clear that this wouldn't be the gentle and passionate sex the pair normally partook in but rather this would be the duo indulging in the much more primal parts of themselves.

"You've gotten good at that," Natsu growled as he spun Mordred around and grabbed her by the legs. "But I wonder if you've gotten any better at taking me in your mouth!"

Mordred half gasped; half giggled as Natsu flipped her upside down. Her legs wrapped around his neck as he leant up against the wall, his hot breath against her now throbbing pussy sending shivers throughout her body.

This only further served to excite her however as both her hands guided her prize toward her waiting mouth. Opening wide, she felt the pressure against her jaw as she took his cock inside her mouth.

Natsu growled and placed his thighs gently around Mordred's head to keep her firmly planted on him as she sucked him off, her tongue getting to work as she licked all around his head though her inexperience at the task was fairly obvious as there was little to no rhythm involved, merely trying to cover the entire area of his head as many times as she could as quickly as she could.

"You've definitely gotten better," Natsu whispered as his tongue began gently lapping against her slick and clearly needy hole. Honestly, he was surprised at just how much Mordred was enjoying this as he lapped up a seemingly endless supply of fluids whilst rubbing her clit with his index finger at a speed Mordred clearly desired.

The sounds of Mordred slobbering all over his dick only served to excite him further as he fully dug into her, now nibbling at her clit as he forced more of his length into her mouth. Mordred's groans in response only spurned him on as he felt his head meet the back of her throat, her moans vibrating against him as he began thrusting into her mouth like a man possessed.

Mordred, being a Servant, was easily able to endure such harsh treatment as her entire face became covered in her own spit. She would never admit it to anyone save for Natsu however the entire situation only made her desire stronger as she felt her lover use her, a future King and the Son of nobility, like nothing more than dirt.

"I think that's enough of a warm up for you," Natsu growled as Mordred was forcibly pulled from her prize and roughly tossed onto the ground, her body getting slightly dirty as her Master came down upon her. "Look at you, nothing but a dirty little slut."

"I'm only your dirty little slut, Master," Mordred replied with a look of complete innocence as Natsu's eyes seemed to blaze with desire.

"Only mine …"

Inwardly, she knew he loved the innocent girl routine. He'd seen his Wife Erza pull it on him numerous time and each and every time afterward the sex was clearly possessive, forceful but also done in a way that both partners could still function afterward.

"My little slut," Natsu growled as drool slowly began to escape from the corners of his mouth, a sign that his baser instincts from his Draconic and Demonic sides were taking hold. "Tell me more?"

"Well," Mordred started with the same innocent tone as she dragged herself toward him, only serving to dirty herself further as she also finally had succumbed to her darker fantasies. "I exist only for Master's personal use, his own personal hole to abuse as he sees fit. If any other man so much as looks at me, I remove their ability to remain as such and present it to my Master …"

"Like a good little bitch," Natsu chuckled darkly as his eyes shifted into that of his Hybrid Form. "That's all you are, isn't it?"

"I am nothing but Master's pet," Mordred replied with her signature grin, the spit on her face only serving to further excite her Master as he grabbed her arms and dragged her the rest of the distance before spinning her around and examining her glistening hole.

"You've been a good girl Mordred," Natsu said as he began to tease her entrance with his cockhead. "Destroyed anyone I've told you to, proven your loyalty to me time and time again and yet I've not been giving you the attention you so rightfully deserve …"

"M-Master," Mordred gasped as he lightly thrust against her entrance. "P-please!"

"Tell me Mordred, would you be jealous if I fucked Arthuria?"

Whatever Mordred had been expecting him to say next that most certainly wasn't it, the haze that had set over her faltering as she looked up at him in confusion.

"Wh-what?"

"Would you be jealous if I took Arthuria right before your very eyes," Natsu continued as Mordred's sex addled mind slowly began to incite fantasy's not just of her watching, but actively participating.

"I-I don't-!?"

The slap against her clit shocked her, the look in Natsu's eyes being that of an experienced predator as her hips began to buck uncontrollably. Looking down she saw she'd slapped it with his cockhead which was now once more raised upward. Looking into his eyes she saw his smirk before feeling it come down upon her again as her mind went completely blank.

Her entire body shook as she cried out and, to Natsu's own surprise, she began squirting all over his cock and lower body whilst thrashing rather violently before him.

"Well," Natsu said slowly as her orgasm finally died down. "I was definitely not expecting that. Then again, we've only ever done it in the bath so maybe she's always been a squirter and I've just never known?"

Looking back down he saw Mordred was somewhat self-aware again, her face flushed and her breathing rather ragged as she came down from her orgasm. Her head slowly moved as she looked his way as an adorable smile etched its way onto her face.

"That … was fucking amazing!"

"It certainly was," Natsu replied as his cheeky grin returned once more. "But …"

Mordred froze as she felt the slap against her entrance once more and realized that Natsu hadn't even entered her yet. Looking back up at him she was half excited for what was to come but also now somewhat nervous since she'd never had an orgasm so strong before.

"Natsu I-!"

"I'll be gentle to start with, I could tell by the way your body reacted and how you almost passed out that you definitely haven't cum that hard before."

"I-I feel so bad now, you haven't even come once yet and now you'll have to hold back for my sake …"

"Hey," Natsu whispered as he leant over her and captured her lips in a chaste kiss. "We've got plenty of time still to get you used to this kind of thing. Plus, I think we've both awakened a new fetish today so I'm happy for now to end things off a bit lighter if you are?"

"I'm surprised you're willing to touch me what with how dirty I am," Mordred muttered with a blush only for his lips to capture hers once more.

"Like I said, we've both awakened something today," Natsu replied softly as he gently pressed the tip of his cock up against her entrance. "Fucking in a dirty back alley like a bunch of animals certainly wasn't how I saw my day going but I'll be honest … I need to cum really bad after all of this."

"Well then," Mordred replied as she wrapped her arms around his neck, the pair both now breathing heavily. "I suppose you can be rough, just don't go too hard."

"Mordred-?"

"Fuck me Master," Mordred purred as she ran a hand over his scarred chest. "Finish what you started and show me my place!"

Mordred's demand was all he needed to hear as he pushed his way inside of her. His dick, despite how wet Mordred was and how coated with her spit and juices it was, still met resistance as he forced it into her.

He always loved fucking Mordred, truly she was the tightest girl he'd ever been with and it was an experience unlike any other.

"F-fuck … so tight!"

"Tighter than Seilah?"

"Yes …"

"Tighter than Robin?"

"Yes …"

"Tighter than Yugao?"

"Yes!"

"Tighter than … Erza?"

Instead of a response, Mordred was given the gift of his cock being slammed right into her tight tunnel, his head pressing right up against her womb as a hand gripped onto both her cheeks, forcing her to look his way.

"Mordred," Natsu panted as he slowly pulled out before slamming his full length back into her eliciting a growl like moan from her as her legs wrapped around his back. "If you were still living … I'd knock you up for this."

"Ngh! For what, being so tight," Mordred replied as Natsu's mouth moved toward her right nipple and nipped at it. "Ah-!"

"Fuck both of your parents for hating you, I'll keep you for myself," Natsu grunted as Mordred began to laugh between moans.

"I thought you wanted to fuck my Father?"

"And I will," Natsu replied with a grin as he moved to kiss her again. "But she'll always have to deal with the fact that you got me first."

"Is it weird, ngh, that I'd wanna be in on that?"

"What," Natsu growled as he pulled Mordred up onto him so now he was the one lying on the ground as she began to move her hips back and forth with considerable speed and force. "You'd want a threesome with myself and Arthuria?"

"Yeah," Mordred panted as she felt Natsu's dick twitch inside her. "Oh, did that excite you? The forbidden act with you at its centre?"

"Have you always been such a kinky little whore or am I just that clueless," Natsu laughed as Mordred rose to her feet and placed both her hands up against the grimy wall, arching her back whilst biting her lip seductively. "I'll take that as a fucking yes …"

Mordred gasped as he came up from behind and entered her forcefully, not even attempting to ease himself in this time as he grabbed onto her left breast. Turning around to face him she wrapped an arm around his shoulder and the pair began to kiss each other roughly, nipping at each other's lips whilst fighting off smirks.

"Mordred," Natsu grunted as the pair separated from their kiss. "I'm getting close."

"Then you know what to do, or rather … you know where it belongs, Master."

The way she said Master wasn't that of their Master/Servant bond. No, this was Mordred calling him Master in a much lewder sense and he felt his instincts fully take hold at her declaration.

Once again, Mordred found herself tossed to the ground however this time she was flat on her stomach as Natsu pinned her down and roughly mounted her. Mordred's face became something none would have ever expected from one such as her as her eyes glistened over and her tongue hung freely from her mouth.

Suddenly, her head was forced into the dirt by his hand, his entire body weight now pressing down on her as he thrust like a wild beast into her. She knew what this was, of course. This was how four legged beasts would mate by pinning down their partners to ensure their copulation was as successful as possible.

And it excited her.

Neither of them could form so much as a word, merely growling, panting or moaning as Natsu kept Mordred locked into place until finally he fully pressed down upon her. With a practiced motion he bit her neck and she, in her sex crazed state, simply began licking at his face.

It was then that she felt it, his head having been pressed right up to the entrance of her womb had forced its way even further inside. The first spurt of his seed was hot, so hot in fact she would have wondered if he had placed lava inside of her instead of his seed.

Instead however she simply came whilst bucking against him, an act that spurned him on as he released load after load of pent up cum into her. Unfortunately, due to Mordred being a Servant, Natsu biting her would have no effect however in the heat of the moment as Mordred's stomach began to bloat neither seemed to care.

They remained in the same position, Natsu still sheathed inside of her for several minutes as both came down from their orgasms. A pool of seed and Mordred's own fluids had pooled on the ground beneath them though her stomach still appeared bloated slightly.

Mordred was the first to speak as she slowly raised her head to look back at her Master, her lover, with appreciative eyes.

"Natsu?"

"Mm?"

"As much as I wanna keep lying in this filthy alleyway naked with you we should probably get our clothes and go back to the Sunny for a shower."

"This was the hottest sex I've ever had," Natsu replied as he rolled onto his side, pulling Mordred with him so that his still hadn't pulled out from her. "I don't care if its weird, we're doing this shit again."

"You bet your sexy ass we're doing this again," Mordred grinned, a slight blush adorning her features as she felt Natsu running a hand over her bloated belly. "O-oi!"

"Imagine if this was our child?"

"I hate being a Servant now …"

"Probably for the best you were one for this though," Natsu chuckled as he moved to massage her breasts. "After all, though I did supposedly sterilize myself after that kind of sex I wouldn't have trusted my power not to … I guess unsterilized me just to get you pregnant."

"Speaking of your cum," Mordred giggled as she placed her hand over his right as he reached the centre of her stomach. "I couldn't really say anything while we were … in the heat of the moment, but why was it so damn hot?"

"Hot?"

"It felt like you dumped bloody lava into me."

"Ah … yeah that makes sense."

"Care to enlighten me?"

"Remember Liz Caster and Liz Saber," Natsu asked as Mordred nodded. "Well after I beat Alucard and fell unconscious they decided they needed their own needs satisfied so we were fucking for a couple of hours until we got interrupted."

"So …?"

"I suppose that combined with the fact that I then abstained from sex all the way until right now I had blue balls."

Mordred couldn't help but laugh as Natsu slowly pulled the pair of them into a sitting position, wrapping his arms around the giggling Servant and simply enjoying their mixed scents.

"Blue balls, more like flaming hot red ones!"

"Ha, so funny," Natsu replied dryly as the pair of them slowly settled down. "But you are right, probably a good idea to go back to the Sunny and clean up."

"Let me get my shirt and jacket first," Mordred replied as she slowly unsheathed Natsu from herself and stood up.

"Fuck," Natsu growled as a steady stream of cum flowed out of Mordred, trailing over to where the boxes where and back again. "We'd better go or you'll get me excited again …"

"Well," Mordred replied with a sultry smile as she placed a hand onto his still fully erect cock. "We do have to have that shower …?"

No more needed to be said as the pair vanished, leaving the alley behind lucky that no one else had discovered their less than civil activities.

Hope you guys all enjoyed and I'll see you in the next one!
