Etherious Natsu Dragneel. A name that strikes fear and intimidation upon anyone who hears it. His time as a Dragon Slayer and former human no more, as he came to terms with his reality and embraced his true self as the ruler of all demons. His tyranny didn’t require any unnecessary explanations, all of his twisted actions were all committed on whims, not a secondary thought behind any of them. If he was bored, or if he felt like doing something, then he’d do it. That was the type of power granted to a powerful being such as him. Like any other form of life, the King of Demons harboured many interests and urges, mostly commanding his slaves to fetch anything materialistic he so desired. 

Today, however. He didn’t feel like mere objects or possessions were enough to satisfy his inexplicable hunger. E.N.D was supposedly a being above that of a normal human, and yet there were certain things that he shared common with the lower beings. That is, an unshakeable libido that needed attention. At first, seeing them as nothing more but eye-candy and source for entertainment, Natsu had accumulated the most attractive women around the country, and forced them into the roles of maids who wore little to no clothing. Without a doubt, such a farce would bring life to illicit thoughts considering how mouthwatering voluptuous some of the ladies were. 

Seeing as whatever he wished was at his command, E.N.D had specifically picked out one of his favorite women, who went by the name of Rias Gremory. She was a beautiful, fairly tall woman with long luscious crimson hair that was rare amongst the others, a symbolization of her demonic ties. A curvaceous figure sporting massive breasts and an extremely plump ass that her old uniform criminally hid for all to see. Rias wasn’t exactly thrilled when she was notified of a private meeting with the King himself, hoping that she would have just blended into the background and escaped his crude acts, unfortunately she was simply too attractive enough and worthy of being the star of the show.

Inside Etherious Natsu Dragneel’s Kingdom….

His land’s environment perfectly encapsulated the Demon King as a whole, a spacious realm that almost resembled the size of an arena, a large throne dead in the center that was only fitting for a ruler such as himself. In the background, there was a powerful fire that was constantly lit, not a gust of wind or geysers of water strong enough to douse it out. That is, because this fire was fuelled by his limitless magic. Rias, much like the other slaves serving his kingdom, feared and obviously wanted nothing to do with the evil ruler, having trouble maintaining her composure under these circumstances, all alone in a room with the man who’s essentially taken over the world. What made things worse, was that she was supplied a very skimpy outfit that certainly was fitting for a man of perverted tastes, suited for belly-dancers that revealed a lot of skin and left very little for imagination. 

“Yes, Master?..” nervously stuttered Rias, holding onto her tiny wrist for comfort.

“Silence. Never speak before me unless I command you to.” crudely responded Natsu, who was resting his cheek on his fists. 

Uncertain of how she should approach answering back in the midst of his intense atmosphere, Rias simply nodded her head in submission, dropping down to her knees and bowing as a form of respect. 

“Good, that’s much better. Now, let’s not waste any time here. There are things that I want in this world. And you’re one of them.” he exclaimed, pointing directly at her ridiculously seductive body. 

“..........”

“You may speak. As long as you know your place, I have no qualms speaking with you until our time here is over.” spoke Natsu.

“I understand, Master..” 

“Do you have any idea why you’re here?..”

The hard-hitting question was difficult to answer, the words struggling to come out of her mouth even though it was so obvious. 

“F-For your entertainment?..” she said uncertainty, finding that the answer was politically correct and didn’t accidentally step on some needles or inadvertently insulted him. When you spoke to Etherious Natsu Dragneel, it was wise to always second-guess and process what you were saying. One mistake is all it took for your bones to be burnt into nothingness by his ungodly flames.

“Precisely. I’m incredibly bored, so much so that I wonder what I should spend my time doing. I’ll trust that you can at the very least do something to help ease my boredom.” 

“I’m honoured that you believe in me, Master.” 

“If you understand what type of outfit you’re wearing.. Then get working.. I’ll reward you generously if you manage to peak my interests like I’ve hoped.” stated Natsu, snapping his fingers which ended up dimming the bright lights casted around the massive room, creating for a more intimate environment, as snake-charming music began playing in the background as any space in this vicinity was controlled by his all-powerful magic.  

Rias wasn’t necessarily much of a dancer at all, having never practiced the art by herself, not that there was any time to consider she was working tirelessly as a maid. And yet, she understood this might be a matter of life or death. If she didn’t deliver in her performance now, tomorrow wasn’t guaranteed. Inhaling a deep breath and calming down her nerves, Rias closed her eyes and allowed herself to be absorbed in the music ringing through her ears, setting the state for an incredible display. 

“Oh, not bad..” commented Natsu, watching as the beginning act unfolded, with Rias holding her hands high in the air and wiggling her hips from side to side, the tiny bells on her revealing outfit playing a matching tune. The crimson-haired buxoms gigantic boobs were swaying and jiggling with her every move, and the shaking of her butt he could’ve only imagined was a sight for sore eyes to see. Her serpentine movements were almost perfect, in harmony with the song echoing the walls in the background, truly a natural-born seductress that had to work very little to charm and entice a man. A few minutes passing by as Natsu sat on his chair, intently watching her as all of his attention was solely on her. 

“Ridiculous.. To think that a being of my stature can harbour such disgusting feelings..” thought Natsu, his brimming pride as the ruler of All finding it shameful to hold such a powerful attraction towards another being. After all, they were supposed to be nothing other than his playthings. And yet, there wasn’t anything else he wanted to in this moment apart from tearing those clothes off of her body, and fucking her until dawn. 

“That’s enough, come here and take a seat.” he commanded, patting his lap and inviting her to come closer. 

“E-Eh?!.. Did I maybe try a bit too hard?.. I didn’t think he would like me that much.. Oh no…” thought Rias, trying to mask her fear by donning a fake beaming smile instead. Even if it weren’t necessarily true, every slave had an appearance they had to keep up. Any sign of disgruntlement was taken as a form of disobeyment, and harboured severe punishment. 

“Of course, my King.” she spoke, walking her way towards his extravagant throne, inadvertently swaying her womanly hips with each step and further convincing the Demon King that he’d made the correct choice. Rias stared down onto his lap and recollected her thoughts quickly before conceding to his whims, closing her eyes as she parked her plump butt directly on his muscular thigh. The outfit she wore essentially contained bottoms that resembled that of a thong, merely a strap running up along her crack and freeing her soft and squishy buttcheeks to enjoy. 

“Now, now. There’s no need to be so distant.. How about sitting here instead?” asked Natsu, grabbing ahold of her skinny waist and easily lifting her slightly in the air, placing her directly onto his crotch as his humongous bulge jammed directly in between the crevice of her asscrack, causing the busty woman to yelp in surprise at the intimate contact. 

“I-Is that his cock?!.. It’s massive.. Oh my, did it really excite him that much?..” thought Rias, her breath hitching as her heartbeat ramped up unreasonably quick. Unable to respond or question his intentions, having a terrible feeling that things might’ve stirred in this direction. 

“Give me a lap dance.” 
The way he spoke his words made it impossible for anyone to even consider rejecting his advances, controlling and powerful to the point where he could never be questioned by anyone or anything. 

“As you wish.” nervously responded Rias, holding her breath as she lowered her head down in shame. It was degrading, reduced to nothing but his playtoy, forced to rub her half-naked backside against his growing hardness. Rias was too sexy for her own good, no matter what she did, any man would’ve found her desirable. Arching her back and really sticking her butt out there, she started moving her hips in tandem with the music, finding herself surprisingly talented at erotic dancing. 

His growls pierced the weakness of her heart, striking fear into her entire being. If he was unsatisfied with their private time together, considering it was remotely unheard of until recently, then Rias could’ve been put into greater trouble. Rias rested her palms on her knees, grinding directly into his crotch and essentially massaging his monstrous length with the soft, squishy flesh of her meaty ass. 

“You truly have an amazing body.. I was right in choosing you first amongst the others..” commented Natsu, running his roaming hands across her exposed figure as if it already belonged to him. He gripped the sides of her hips, before descending downwards and running his palms along the smoothness of her cheeks. The impromptu buttjob forced his erection to grow further and further, and considering he was lodged snugly in between, Rias could feel him growing. 

“E-Eh?!.. It’s getting even bigger?!.. That’s impossible.. His size from before already felt too big..” 

He caressed the entirety of her womanly body, trailing up to momentarily fondle the suppleness and weight of her mountainous breasts, holding back embarrassing moans and squeals as to not interrupt her master during his time of feast. Natsu was evidently absorbed in her ridiculously proportioned body, even attacking her thighs with his grip, slapping them and hearing the clap it made for future reference. 

“Bounce on me.” 

Rias nodded her head, taking his advice and lifting her ass high up in the air before slamming it down roughly onto his rigid meatpole. Repeating the same motion over and over, leaving Natsu with a rear-end view of her sideboob jiggling up and down, with the rough collision of her cushiony ass. His sharp nails lightly scratched her perfect skin when he hurriedly gripped onto her hips, encouraging her movements by pulling her down onto his apparent hardness, mimicking the motions of fucking and leaving Rias with an inexplicable sensation forming in her belly. Conflicted between lust and absolutely hating doing this for a man that she harboured hatred towards. 

“I-I don’t like this.. God, please let me go.. I have a bad feeling where this is heading..” thought Rias. It was obvious for anyone to see that Natsu was having fun, maybe a little bit too much of it. There wasn’t much hope that he’d suddenly lose interest now, probably pushing things further and attaining whatever he wanted, as per usual. 
“That’s enough.. It’s more than hard enough.. You’ve done well so far, what’s your name?” 

“I-It’s Rias…” she nervously muttered, gradually slowing down the rubbing motion of her ass that pushed it’s meat against his crotch, lifting herself up off of her seat and being rewarded with an aggressive spank to her cheeks, leaving her yelping in pain. “Ouch!...” she thought, turning around instinctively and hiding the redness that was sure to come from the spanking, secretly rubbing her pained flesh as she nervously smiled at the man. 

“You’re different from the others, Rias.. When I look at you, it’s like there’s a beast awakening inside of me.. Do you see this?” asked Natsu, pointing towards his raging erection, that simply didn’t need any direction considering it was so large and thick that any lady would find themselves staring. 

“Y-Yes.. I do..” 

“You were the one that made me like this. As a result, I believe it’s only expected that you’re the one who does something about it. Get down on your knees.” he commanded, as Rias felt her lifetime shorten from stress.

“Oh, no!.. I knew it.. Oh gosh, he wants me to-.. Ah, what did I do to deserve this?.. I never wanted to do something like this with a monster like him!...” 

Of course, all of those internal thoughts went unnoticed. Obediently, and swiftly listening to his every command before her mind could even process it. That’s how accustomed everyone was when listening to E.N.D. She wasn’t naive or ignorant enough to not understand the intention of sitting down on her knees, bracing herself for the future and internally praying during the brief moment she had kept her eyes closed. “Calm down.. I can’t show myself being panicked.. Everything’s alright.. After this, I’ll be just fine..” 

Rias’s eyes opened and was immediately greeted by the cold expression of the Demon King, probably the first time they’ve been in contact like this. She felt her bones shake as her body went chilly. He casually dropped his hand down onto the top of her head, tugging at her hair and pressing her face onto his meat, causing her nose and lips to feel the heated arousal. 

“Suck me.. Use that mouth of yours until I cum.. You can’t stop unless I tell you to.” instructed Natsu, maintaining that cool exterior while his harsh words left no room for opposing answers. 

Rias couldn’t bring herself to verbally concede, unable to pretend by claiming that she wanted to do this. Instead of responding to his commands, she immediately started unbuckling the front of his pants, silently working without uttering a word unless necessary. Luckily, he didn’t find this behaviour insulting. If anything, he might’ve preferred less chit-chatter and more action. Rias was trying to trick herself into believing that this was nothing more than a bad dream, but the instant she freed E.N.D’s monster from it’s confinements, she was quite literally smacked back into reality. The nearly foot-long slab of meat swung out and slapped her directly on the face, forehead down to her lips. Closing her eyes in reflex and turning her head to the side, his big cock rested on her cheeks.

“W-What the hell?!.. It’s even bigger than it looks!.. I-I’ve never seen a dick like this.. And why is it so hot?!..” 

A wave of panicked thoughts ran through her mind, almost dizzy from how quick everything was transpiring. One second she was working as a maid, and now she was on the verge of steadily becoming the Demon King’s cumdumpster if things proceeded as is. It was obvious that she was being treated as nothing more than a toy, and considering she was considered amongst the rest as his personal assistant and being demanded that she relieved his erection, it was obvious that her fate was shifting. Maybe as his personal slut, her safety would be guaranteed. But it still entailed undesirable conditions, which was that she must service him in ways that only harlots would enjoy.

Rias recovered from being whipped by his length, grabbing a hold of the base of his manhood and backing away until he was correctly aligned with her lips. Sucking his cock wasn’t ideal, but neither was dying as the punishment either. Closing her eyes in preparation, with her heart beating loudly out of her chest, Rias carefully opened her mouth, jaw hanging wide and welcoming in the absurdly large girth. Having never inserted something this sizeable within her lips, Rias struggled to fit him inside of her warm orifice. Stretching her mouth as far as possible while holding in a grunt as to not sully his experience, breathing intensely through her nostrils as the taste of virile musk washed through her taste buds. It was a salty, distinct taste that not many could get used to, but it wasn’t necessarily unpleasant either. The bulbous, mushroom cockhead sucessfully engulfed behind her soft, plump lips as her wet tongue caressed underneath it. 

It was naive to assume that this blowjob would’ve progressed like the other few times she’d done it in the past, eyes widening in pure shock when Natsu had gripped onto her hair and yanked her deeper onto his cock, shoving practically half of his raw manmeat inside of her wet cavern. 

“Nngghhh!~...” she moaned in discomfort, possibly pushing her limits without even being completed with half of the job. It wasn’t comfortable at all having to suck on something this big, pushing the limits of what her mouth could handle, especially considering it was lodged so deep. While Rias didn’t expect him to sit there motionless and let her do her thing, she hoped it wouldn’t have gotten as rough as it was getting. 

Natsu’s fists clenched a ball of her luxurious hair, and grunted profusely as he forced his length down her gullet, tears of slight pain watering her eyes as she hopelessly murmured around his cock. Practically twelve inches of pure manmeat rudely invaded the back of her throat, making her gag and nearly choke on his crotch. Rias’s body was screaming at her to retreat, but that wasn’t something listed in her tiny list of options. He grinned at the sight of watching her incapable of swallowing his cock, watching as her cheeks grew slightly red from the lack of oxygen, holding her down until he was satisfied. Nearly sheathed to completion, her nose was pressed right up against his pubic bone. Spittle and saliva escaped the sides of her lips that were latched tightly around the circumference of his cock, gurgling noises emanating deep within her throat as Rias’s milky thighs shook together as a confused moan vibrated around his girth. 

“Not bad, Rias.. I’m impressed.” he said, rarely complimenting anyone over anything. For some reason, Rias found herself thrilled by the comment, perhaps subconsciously finding herself truly being morphed into his willing slave.

"Let's finish this quickly. There's better things I want to move on too." 

E.N.D showed off his demonic nature, callously grabbing ahold of her head from the sides, lifting himself off the seat of his throne and standing in front of her. Jabbing his hips forward and spearing her gullet with his wet cock, humping her face as he fucked it. Obscene, lewd noises sputtered from her watering lips, disgruntled with her facial expressions scrunched in pain. Rias didn't know what else to do other than stay sitting there patiently on her knees, allowing her mouth to be used as a toilet for his cum. He was completely intent on ejaculating sooner than later, brutally pounding his hips against her face. 

"I-I can't breathe!.. This is awful!..." 

Rias's teary-eyes were shut tightly without a tinge of light passing through, her head jerking back and forth until the massive rod throbbed within the suction of her lips. Having to survive only a minute or so of the abuse before he was ready to cum, roaring an animalistic groan that reverberated across the halls, the massive geyser of white spunk instantly filling her mouth like a pouch full of cum meanwhile the rest was discarded directly down her stomach. Rias was forced to gulp it down no matter the taste, freeing herself and peeling her head away from his crotch the instant he relented the grip on her head. Coughing and sputtering curses as she spat out a couple globs of cum that stained her beautiful face.

"Oh?.. Is my semen that distasteful that you can't swallow it all?"

Rias shivered at the tone of his voice, certainly not impressed by her lack of dedication.

"I-I'm sorry, forgive me!.."

"Me?.. Forgive you?.. Don't be ridiculous.. I should punish you for this.. I know.. I won't let you leave my side for the rest of your life.. I'll keep you with me and do whatever I want with this slutty body of yours." he growled, lifting her up by a single arm, carrying her onto the throne and placing her legs over his broad shoulders. 

"W-Wait!.. I don't want this!..." she thought, imagining that she had the courage to utter those words of resistance. True, Etherious Natsu Dragneel wasn't ugly by any means, in fact he was attractive. His member was an abnormal size that could be alluring to some, too. But, that awful personality, and his twisted evil nature was what deterred Rias from wanting this. Hopelessly, internally coping with the situation as her tight snatch was on the verge of being stolen away. She was slightly wet from a panicked reaction of being used to extract his semen, so he didn't even bother to consider her condition. Pushing his meaty cockhead at her entrance after slipping her undergarments to the side, easily overcoming her resistance by wiggling his hips slightly and force-feeding it inside.

"Unnggghhhh!!~... S-Shit!..." exasperated Rias, in disbelief that a penis this huge existed, noting how incredibly full she felt from the mere penetration of his wonderful length. She swore she didn't like it, but it was undeniable that this Demon's cock was levels beyond the rest. He didn't care about anything other than making himself cum, grabbing two handfuls of her milky tits and fondling them to his heart's content.

"S-So rough…" she muttered under her breath, face flushed and averting her eyes elsewhere while E.N.D helped himself to her voluptuous, sexy body. He stirred his cock deep within her warm cunt that wrapped impossibly tight around him, smacking the back of her thighs and making their skin clap as he roughly thrusted against her sex. Taking what he believed rightfully belonged to him, pounding her hard and absorbing all of the unrestrained moans escaping her lips.
Minutes passing by as he maintained their position, but gradually increased the intensity of his powerful, vigorous hips.

"I'm gonna-.. I'm gonna!-..." screamed Rias, reduced to nothing but a moaning slut.

E.N.D found himself absorbed and drawn towards her immaculate figure, devouring her form with his gaze while insatiably ravaging her perfect pink pussy. He couldn't help himself but groan as his hips flailed, buckling wildly as he simultaneously reached his ejaculation when Rias squirted powerfully from the abuse of his cock, one that left her stretched and sore after only a single round. Rightfully, he used his newfound cocksleeve as one should, dumping all of his cum within her womb as he shoved himself balls deep. 

"Aahhnnnnn!!!~... Oh, fuck!.. Oh my God!!!.." panted Rias, squirming and holding onto E.N.D's muscular figure as she spasmed uncontrollably due to an orgasm. Body limp upon settling down and breathlessly gasping for air, a look of defeat as the Demon King pulled out of her gaping hole and unloaded the rest of his semen onto her stomach.

"Don't worry, Rias. The night is still young. Our time together is far from over."

"Ha…. Ha….. Ha….. Yes, Master…"
