Hotel Chaldea Ep. Merlin & Merlin (Patreon)

"Did anyone ever tell you that you guys sound kinda similar?"

"I've been told."

Merlin was a devilishly handsome man. Quite literally so, in fact - he explained that it was from his incubus side. His smile was said to be able to charm the panties off of even the most uptight of nuns. Even before panties were even a thing that nuns wore! "It's a privilege to share a voice with at least one version of my King," he said, bowing slightly.

"What he means is that he has pretended to be me to prank girl me."

Arthur was no less handsome, though he was more of a prince charming type. With that evergreen boyish charm and the confidence that radiated from him. He wore an impeccable white suit that made him look like he'd stepped right out of a movie. 

"Anyway - can you do it?" Arthur asked.

"Can't you?" you asked in turn. It was a bit of an odd ask, after all.

"I've got a girl I'm interested in already, and to be honest, I just am not interested in my Merlin at all," Arthur said, scratching the back of his neck. "Been there, done that, absolutely not making that mistake again."

"Oooh, so unlike my King, you tasted the forbidden fruit, huh?" Merlin asked with an almost girlish giggle. "I'm surprised you could go back after that."

Arthur rolled his eyes. "Continuing with the honest streak, she's too much for me," he said.

"And you think an actual succubus won't be a problem for me?" you asked in turn. "Look I've done some pretty wacky things in my time but even Medb warned me against her."

"That's where I come in!" Merlin said. "I'll be assisting you!"

"So I'm basically going to be the advantage in a mirror match?" you asked.

"Precisely!" Merlin said, "I'm glad you're quick on the uptake, having to deal with the knights all the time is really terrible!"

"You know I should smack you for disrespecting my knights," Arthur said, "but at this point I get your pain," he said with a sigh. "Anyway, are you in?"

"Well-"

Later that day...

Merlin's powers coursed through you. You stood in front of the white haired magician, the Kingmaker, he who decided the course of history, one of the most important figures in the western world, probably the single most well known magician among the modern man, with international fame... trying not to look at his overly sexy incubus body, wearing only a very tight, borderline painted on speedo.

Stupid Sexy Merlin

Even worse was that Merlin in front of you was also stupidly sexy, in a floral pattern lace bra and panty set, leaning forwards slightly, giving you a mischievous smile. 

"What's the matter, big bro?" she asked, looking at Merlin behind you. "Lil' sis a bit too spicy for you to handle on your own?"

"For legal reasons I am no longer allowed to operate solo in Chaldea," Merlin said, giving a thumbs up. He struck a pose with finger guns then, pointing them at her. "You've gone too far! You've stepped too much and interfered too many times, your bratty behavior can no longer be condoned."

Merlin, or Lady Avalon as she preferred to be called, grinned. "On whose orders?"

"Master? Your King? My King? The United Nations? Several Lostbelt Kings? Every authority figure from Romulus to Edison?" Merlin said. "Seriously even Medb thinks you're out of line."

Lady Avalon's eyes turned to you. "And you're the hero who's come to take down the evil succubus?" she asked. "I see you've had an arduous and very hard journey," she said, licking her lips. "Full of challenges and fraught with danger..."

"Hero?" you asked, tilting your head. "Nah, that's more of Ritsuka's job. I'm more of a debt collector really," you said, smiling. "And the debt I'm collecting is your debt to society."

"Waaa!" Lady Avalon pretended to be scared. "Are you going to do lewd things to me with that?" she asked, looking at your crotch. Given how she was dressed, you could not be blamed for the fact that your erection was starting to show. Merlin had forced a similar speedo to his on you, and though you weren't quite as overgifted as Merlin was due to the incubus blood coursing through his veins, it hardly mattered once you started getting hard, it was still so skintight that it was showing off every last detail of your junk, even the wrinkles of your ballsack. "All of Medea's potions and Medb's techniques won't avail you-"

"We know your weakness!" you said, pointing at her.

"Indeed!" Merlin agreed, his staff appearing right next to his hand, he grabbed it and pointed it at you. "Your behavior has been allowed for far too long, it's time for some strict discipline! I'll increase your strength to the max, now do it!"

Merlin's powers burst all at the same time and you felt as if many instances of the same spell were cast at the same time, like he had somehow stacked up buffs in a videogame somehow, and they all came into action together, bolstering your strength to a level the likes of which you'd never experienced, you felt your bloodflow quicken and your cock become fully erect, still covered in the weird speedo. You could recognize it now as the same kind of thing you'd worn when you were with Jeanne, a long time ago- but modified! It was definitely modified to fight her!

You understood now! You were the key piece, and no doubt, the weird skintight speedo was protection against this succubus' powers!

Rushing forward, you caught her before she could retreat, already she was forming a whole bunch of flowers around her, and her face had changed from barely hidden smug amusement to panic as you grabbed her, and within moments, bent her over your knee.

"You horny little brat," you muttered, "with your honeyed words and forked tongue, you've been causing all of the men at Chaldea to be ashamed of themselves, thinking they're developing an incest fetish, and it's all your fault!" you called. 

That was... mostly bullshit. Mostly, people paid fortunes to hear her call them "big bro" while she was draining their balls and vital energy, in fact!

But still, she wasn't supposed to do that to the staff!

"H-Heeey!" she cried out, "this wasn't supposed to happen!" she cried, "I'm supposed to be the invincible smug sexy woman type!"

Merlin grinned. "You got too overconfident! Master would've let you off the hook, that's why we didn't bring her! You have no power here!"

"The references! They're too outdated!" Lady Avalon cried.

You put a hand on her upper back to hold her in place as you set her on your lap. Merlin conjured a chair made out of flowers that propped up from the... tile floor? whatever! it was there and it was comfy and you could sit on it as you raised your hand. "I'll discipline you!"

"Nnngh, have mercy on me, Big Bro! Please don't break my butt!" Lady Avalon cried out.

"No," you responded, as your hand came down, falling like lightning and exploding with a thunderous crack when it landed on her mostly exposed pale butt cheek. She was slim but very womanly, she might not have the excessive femininity of others but she definitely had an overwhelmingly perfect shape and oh, the feel of her smooth, soft skin, almost like satin, as your fingers began to knead her now reddening asscheek, while she held in her voice. 

"Again!" Merlin called. "Until she can't hold her voice back anymore!"

Right!

You were getting distracted with her overwhelmingly perfect ass, but you were here to mess it right up. "You bratty girl, you're trying to seduce me even when I'm punishing you," you said, "now count the blows! If you miss one, I'll start again from scratch! Count up to twenty!" you called, raising your hand.

Once again, you landed a powerful spank that resounded across the mostly empty room, but she didn't emit one peep... and then you hit her again, and her breath came out in a short gasp, but she didn't let up.

The fourth spank actually forced a groan out of her, and she turned her face to you. "This is only getting me off~!" she called.

You grinned. "That's the point," you said, then looked at Merlin, who gave a thumbs up. "Now count!"

She didn't.

Your spank was as thundering as the first, and she squirmed and shook and she was obviously enjoying it, she was deriving pleasure from the pain, the clear hand prints were starting to blur together as her ass was turning redder and redder with each spank, and you could feel that she was wetting her panties.

Already, her juices were dripping and overflowing from her underwear, some of it getting on your legs. Their sickeningly sweet smell was pervading the room, and it was a chore and a half just to remain concentrated and not just rip her panties off and lay into her like a feral beast.

Again and again, you slapped her, and by your count, you were at ten spanks when she once again broke, groaning out loud, then looking frustrated. "W-Why-- why am I not cumming!?" she cried. "I'm- I'm- I'm enjoying this so why- Big Bro what did you do!"

"Oh, nothing much, just made him an Anti Merlin Weapon," Merlin said.

"I'm not Merlin," Lady Avalon replied automatically, "wait- what do you mean?" she asked.

"You surely have noticed that your Charisma and suggestion powers have no effect? On top of that, he has the ability to deny you an orgasm, no matter how much he attacks, you'll never cum unless he allows you to!" Merlin called, laughing.

"H-How?!" Lady Avalon cried out. "How could you be so cruel, Big Bro?.. do you prefer Onii-chan? Ngh, I need to cum, I'm right at the edge-"

"You can only cum if he allows it," Merlin said, turning to you. "And without your succubus abilities, you're facing an opponent that Medb has acknowledged," he said, pointing at Lady Avalon. "It's your doom!"

"Nnnghh-"

"Count up to twenty," you said gently, "and I'll let you cum," you said, then you hit her ass again, hard. She shivered and shook in place.

"Agh, e-eleven!" she said.

"No no, you start from one, young lady," you said, caressing her ass softly. "Again!"

Your hand produced another earsplitting crack as it landed on her now mostly red ass, and she cried out in pain and pleasure, at the same time as she called out a weak "ONE!" 

You hit her hard on the other cheek, and she called out the two, and then the three, and four, all the way up to eleven until you grinned, showing all your teeth, and then rapidly spanked her twice in quick succession, and as she called the eleven, you grasped her ass again, making sure to put pleasure on the no doubt burning pain by giving her some soft caresses. "Nope, you missed one, back to the start," you said.

"Nngnhooo!" she cried out, "'s unfaaaair," she swallowed, you che, cheetahhh~!" 

You laughed. 

"Man this is almost cruel," Merlin laughed as well. "How about we allow her a little reprieve?"

"Alrighty, your punishment will end when you get to count all twenty spanks," you said, running your hand from her ass up her back, "but we'll allow you a small, tiny little orgasm, if you can make us cum, with your bratty little sister holes."

Panting, her eyes twinkled. "O-Okay! Bring it on! I'll show you how much I'm worth!"

"Oh, what a minx, to think she was pretending to be breaking!" you laughed, Merlin laughed, Lady Avalon wasn't laughing when Merlin grabbed her by her hips and after a little movement, set her up so you and him could spitroast her.

He didn't waste any time, pulling her fancy but ruined underpants to the side, and immediately shoving himself in deep, not bothering to remove the enchanted speedo. Lady Avalon cried out in pleasure. "ngnh, even this can't make me cum!?" she cried out in surprise.

"Oh, didn't I tell you? Basically, from the moment he first hit you, the effect where you can only cum by his command was made permanent until the enchantment is undone!" Merlin said, laughing. 

"Wa-wait, permanent!?" she cried out. 

"Well until it's undone," you said, assuaging her worries a little bit. Of course, Merlin had to undo it himself... both of you agreed it was better that he hold onto that authority, just in case she managed to work her wiles on you. "This is what you get for being a cocktease to every male staffer at Chaldea!"

"Oi oi oi! It's not my fault that I'm the cutest little sister!" Lady Avalon protested.

Merlin cackled, grabbed her hips and grinned, as he began pounding her.

You nodded, presented your cock to her, covered just like Merlin's with the weird latex-like speedo that somehow didn't impede sensation at all, and she opened her mouth, taking you into her mouth. Your hand on the back of her head forced her down, and showing just how much of an expert slutty little sister she was, she deepthroated you quickly and easily.

You both were merciless, doing her hard, fast and powerfully. Merlin even grinned, as he stuck a finger on her asshole. "oh ho ho! So you don't use this one very much! Okay partner, I'll leave this one to you, I know it's gonna be gloriously tight!" he said. "She's almost like a virgin!"

Lady Avalon cried out in agonizingly potent pleasure as he fingered her ass, the vibrations of her throat around your cock pushing you to the edge, and then a final pull back prepared you for the first orgasm of the night, as you closed your eyes and then slammed yourself home, going as deep as you could, feeling like you were lost to time for an eternity and a half the moment the explosion of pleasure, a pink haze that overtook your mind, took over.

After a million years later, you opened your eyes, and were brought back to reality, where Merlin was stroking the last few spurts of his cum from his cock, all over her back and ass, though they disappeared in short order, between blinks.

You ignored that.

"Alright... if you want to keep your sanity," you groaned, "you'll be more diligent about counting the blows now," you said, "now- I believe we should increase the difficulty since she took her first lifeline!"

"I agree," Merlin said. "Here, behold! The Excalipaddle!" he shouted, raising his hands and in a flash of golden light, procuring a gold and blue... paddle. Same design as a very familiar sword, but... a paddle.

Lady Avalon's eyes widened.

It would be a very, very long night for her, and it would take her many, many attempts to actually get through the 20 slaps correctly. So much in fact that you had to actually take a few golden apple smoothies to keep going. But hey.

At the end of the night, she finally counted all the way to 20, and even fell asleep in your arms. After cleaning her up, she even managed to look like an innocent little sister instead of the lewd demon she really was.

Which would've all been well and good if the next day, when you went to sleep, you came to awareness inside a dream. Already wielding the Excalipaddle, and with a very familiar girl calling herself your little sister, already bent over your lap.

"I feel like I might've made a terrible mistake," you thought-spoke in your dream, "and somehow, I can't seem to regret it."

Lady Avalon gave you a double peace sign. "Even if you don't remember all your dreams, I'll make sure to make every last one of them soaking wet~! Unlike Master, that count isn't here to deny me access~"

"You brat," you growled, as you began the process of disciplining her all over again... "I'll show you your place!"
