Hotel Chaldea Ep. Artoria Avalon & Lady Avalon (Patreon)

"You have to understand my doubts, not many people pass on a threesome with two extremely attractive women, and I have it on good authority it's not the butt stuff, so... what gives?"

Arthur, he who most resembled the mythologic idea of a King Arthur among all those who claimed that name, chuckled. "I've got a... prior engagement," he said, pulling his phone out of his white suit jacket's pocket, and flicking the screen on, revealing a message sent through the internal Chaldea messaging app, a photo sent to him of a familiar redhead, wearing a fancy purple getup and glasses, and a less familiar brunette also wearing glasses, the latter of which was tied up, and the former was throwing a peace sign with one hand and taking the picture with the other.

"Fair enough," you agreed, raising your fist for him to bump. "So I'm to keep your stalker busy until you're done over there right?"

"Right. You-know-who already set up a plausible scenario to keep both our stalkers busy," he said, "so the rest is up to you."

"Alright, now don't you screw this up," you said.

"I've got this, you take care over on your end too," Arthur said.

And with that, the two of you parted ways. One of you was going to meet a pair of women for a fun engagement, and the other, was walking into the hell of a perpetually hungry sexual beast, a succubus that devoured men as easily as she ate noodles.

You wished the poor unfortunate soul good luck in his endeavors, he'd need it if he planned to survive a night with Ritsuka without backup.

And as for you... well...

You didn't have to go too far, as the room prepared for you was only a two minute walk away from where you'd separated with the blond pretty boy that would soon become a dried out husk that used to be a handsome lad. It was at first, something of a blast from the past to you. Walking into a room and feeling the pheromones in the air, seeing the otherworldly factors start to play in as the world changed around you... once upon a time, you were totally oblivious of the magic involved. Now, you dealt with crazier things than that just to pick your daughter up from her crib, because Medea didn't quite seem to understand the concept of restraint.

Now though, the world around you shifted into pink hues and the light grew dimmer, soon it felt like you had stepped into another world, an erotic world, one where nothing needed to be said because actions spoke a million times louder than any words... a world where bodies communicated with far more efficiency.

And more importantly, you stepped into a recreation of a pink sex dungeon, at the center of which was a wall, attached only to the floor and ceiling. Upon that wall, there were two lower bodies.

Two fairly recognizable butts, at that. Different, in their subtleties... but recognizable nonetheless. The perfectly perky, peachy and rounded butt, it was unmistakably the one shared by every variant of Artoria in Chaldea, from Lily all the way to the King of Storms, each and every one of them shared that perfectly shaped butt that could make a monk drool. More importantly. No marks from the removal of pubic hair meant it had to be Lily or Caster, and a slight lack of muscle definition in the thighs and calves suggested Caster.

And left of that was a slightly bigger, slightly wider butt, bigger, but with its own charming curve, more of a heart shape, sat on slightly thicker thighs. It took a moment to go through your brain to arrive at the correct conclusion, but it was in there. You could indeed put a name and face to that ass, it was Lady Avalon, or Miss Merlin, not to be confused with Mister Merlin, whom she insisted was her older brother. Complicated stuff, but irrelevant in the face of two delicious asses sticking out of a hole in a wall.

The wall then shifted, magically, showing images of their faces, their names, and a set of stats, as well as big and colorful text. 

"The Great Wizard of Flowers Merlin Presents: The Avalon Assembly," it read.

Then the instructions began to appear, as if typed into the wall one by one with a typewriter.

Since you had already correctly identified the participants, the first part was crossed out as soon as it was written, and then disappeared, it instructed you to use your hands, eyes and even your mouth, but not your penis, to try to guess who each of them was.

The second step was to get them ready for sex, again, you weren't allowed to use your penis, and most crucially, you weren't allowed to touch their pussies. 

The event was, as Arthur had suggested before, butt stuff related. He'd been vague on details, clearly on purpose, but it was becoming rapidly clear what this was going to be all about. You looked around, then shrugged, and approached the wall properly this time. First, you wet two fingers with saliva, and then began to toy with the Pendragon Peach to your right, pressing your fingers against her butthole and applying only the barest of pressure, wetting her rim and giving her a nice and soft massage.

When it seemed like she was starting to feel it, and you could feel her muscles twitching in response to the stimulation of your fingers running along her crack and playing with the entrance to her bumhole, you then stepped away from her, and to the left, grabbing each of the fatter cheeks to the left with your hands, squeezing them enough to delight in the feel of softness that accompanied the slightly bigger, rounder and more fleshy bottom.

Lady Avalon was significantly less resistant. She responded much more easily than Artoria Caster did, and clearly enjoyed herself without reservation, as you spread her cheeks you teased her butthole with your thumb, and found her making absolutely no effort to keep you out, and so you once again wet your fingers with saliva and tuck first one, then when it went easily, you entered her with the second finger, your left hand becoming busy exploring that remarkably soft, warm and flexible asshole. She hardly required any help, what a wonderfully slutty bottom.

Meanwhile, you used your other hand to spread Artoria's butt and open her up to go down on her behind. Servants, of course, didn't actually use the asshole for its intended purpose in humans, and this particular set of servants didn't even have that use for their buttholes in life, theirs were purely for sexual purposes, and it showed in how easily your tongue went into Artoria Caster's asshole.

These two were never humans after all... it was sometimes hard to imagine even thinking about doing what you were doing, but it was hard to care when she tasted so good, and the previously resistant ring of muscle that had held closed so tightly didn't even try to keep your tongue out.

Within moments she was already welcoming you in, and trembling all over, but you weren't about to stop, pulling back, swallowing saliva that had taken her surprisingly sweet taste, and licking your lips before diving into Merlin's ass, savoring her as well, while your right hand pushed the middle two fingers into Artoria Caster's asshole, while you resisted the urge to use your palm and wrist to stimulate her pussy as you toyed with her ass.

If Artoria Caster's ass tasted unusually sweet, Merlin's tasted lewder than a pussy, it was an intense taste, not quite comparable to anything else, comparing it to the taste of a regular pussy, much less an asshole, was like comparing properly prepared and well seasoned sushi to grabbing a rotten tuna off the street and taking a bite, it was like someone had told her she was supposed to have a fishy taste but she didn't quite understand that it wasn't a compliment.

As amusing as it was, you didn't keep devouring her butthole, instead you pulled off and stuck your fingers inside her again, separating them, curling them this and that way, doing the same on your right to Artoria, and reaching for their weak spots, using the lubrication you'd left in them in the form of your saliva to slide a little easier, making it obvious they were quite ready.

So much so, in fact, that the wall had already written out your third objective.

You resisted the urge to chuckle, as it just said "Deliver the cream to the chocolate factory", it was so dumb and ridiculous that it was actually breaking the sexy mood a little, but with these two sexy asses side by side, and getting up close and personal enough to grab a taste... Well, it was still the month of love, maybe you'd let the chocolate pun go.

You stood up and realized that you were naked... again, a relatively common effect that took you back, the bounded fields, as Medea had explained, could be configured to do all sorts of things, and with the help of some of the greatest inventors in history, Chaldea had designed lots of means to use them... for sexual purposes.

The wall dismissed all the text and images of it, and instead, there was a coin laying flat. You raised an eyebrow, then realized what was happening, when you saw that the face of the coin had an arrow on it. It suddenly stood, and then began to spin wildly, before finally stopping while it was pointed at the left, towards Merlin's ass. Thanking the wall for its prompt service with a nod of acknowledgment, you moved to Merlin and spread her fat cheeks with one hand while directing your cock at her asshole with the other.

Taking a deep breath and reminding yourself to keep your wits about you, you pushed into the tight, hot and flexible maneating hole, and immediately felt like it was a terrible mistake to not take a few more moments to prepare. Having fingered and tasted her prepared her for penetration, but it certainly had not prepared you for penetrating her. It was an almost ungodly pressure, devilish even, befitting her title of a succubus, a sexual demon the likes of which mortal men could only tremble before.

You only realized you were hip deep when you kept pushing and trying to sink further into that sweet embrace but found nothing but her soft cheeks pressing against your crotch. Both of your hands grabbed at her waist, what you could reach of it, and realizing there was no other way to withstand this than taking charge, you used all of your mental strength to pull yourself off and then slam into her, with a cracking thunderclap as you made contact with her cheeks again.

And again.

And then you did it again, harder this time, picking up speed, setting a climbing rhythm, spearing into that ridiculous, inhuman asshole, and fucking her thoroughly and in earnest. Her pussy gushed its warm and hot fluids, they almost burned as they sprayed on your legs and crotch, you could feel them on your balls, her legs and internal muscles were trembling, she was wrapping around you as you fucked her ass mercilessly.

It was hard to think, it was hard to resist, and you couldn't even tell if she was cumming, or just taking her sexual appeal to the next level, but it didn't matter. Your mission was to fill her up from behind, and you weren't about to fail it, so you tightened up your muscles and laid into her with the fury of an exploding star, ramming your cock as far into her ass as it could go, and then exploding within, a supernova-force ejaculation that started from the very depths of your being and coursed through your entire body, before being deposited in wave after wave of thick, hot, sticky and potent babymaking juice, poured into the wrong hole for reproduction.

Panting, you pulled yourself back and away from the sex fiend, befitting the name of semen demon, her asshole tightened up and closed and didn't let a single drop leave with your cock, you were almost shiny clean in fact. 

However...

You weren't done. Feeling reinvigorated and energized after your first orgasm, in fact, feeling even better than when you first went in, you turned your attention to the other ass in the room. If Merlin also went by Lady Avalon, then Artoria Caster also went by Artoria Avalon... there was nothing everdistant about them, but it was time to reach into the utopia, and even invade it!

Your cock was hard like steel and you didn't even need to hold it, Artoria's cheeks were closer to each other and you needed both hands to open her up for penetration, you squeezed her cheeks hard and her asshole twitched, that moment was enough for you to pierce your rod into her exit-only hole, her anus resisting briefly but then yielding and surrendering to the invading force.

She had clearly realized you were fucking the other girl beside her, you didn't know what was happening on the other side of the wall and knew that magic was keeping you from hearing them, so nothing mattered other than the sensation of that ass that both was prepared for you, and clearly, hadn't prepared enough for you.

Artoria Avalon was one of Ritsuka's closest confidants, probably only behind her literal wife, Mashu in terms of closeness, and it was obvious that she had been the target of Ritsuka's perversion quite a lot. Effort, training and natural talent worked together as her fairy ass tried its hardest to pleasure you, it was charming and lovely, not so overwhelming and more welcoming.

She was hugging you, squeezing you, wrapping around you, you weren't being devoured but you were definitely being taken in. If Merlin was a wild beast that tried to eat you up without subtlety or restraint, Artoria was a subtle but no less dangerous ambush predator, luring you in and then attacking you all at once from every direction.

Different approaches, different levels, different execution, but by no means less pleasurable, and you had to force yourself to actually react, to pull out, before she could just make you cum like that. Being a bit sensitive after your first ejaculation wasn't making it the least bit easier, and you had to pull out the stops and start putting more effort into holding it together.

The semen demon to your left made it nearly impossible to tell if she was cumming, her asshole twisted so needily and greedily that for all you knew she was in a permanent state of orgasm, but the sword fairy was more straightforward and simple, it was impossible to say which one of them had the edge...

But you knew that you had an edge over them, and that was that you knew what you were dealing with, but they, did not. So you could change and alternate the way you worked, keep them guessing, fucking Artoria more softly, more sweetly, than you had Merlin, slower thrusts, at first not quite reaching all the way in, but then swooping for long, deep and meaningful penetration, ensuring that she never had time to get used to it.

It worked, she was trembling within moments, and before you knew it, she was coming apart, becoming a shaking and twitching mess.

It caught you by surprise when all of her muscles suddenly seemed to tense and spasm at once, the crushing pressure and heat on your cock catching you unaware and forcing you to hold onto your orgasm by the skin of your teeth, and only when she finally lost her mind and erupted into explosive orgasm did you let go, opening the floodgates and letting the accumulated pleasure discharge into a shattering orgasm that made stars explode at the back of your head once more, causing you to shake with every spurt of cum, accompanying it with a thrust of your hips, until the last droplet of your semen was milked out of your cock by her desperate fairy asshole.

Panting, you pulled back, and grinned.

A poorly modeled 3D golden cup appeared in front of you, on the wall, with the text "You're winner!" plastered above it. It was so stupid you couldn't help but laugh.

It was even funnier when the wall suddenly disappeared, and two thoroughly fucked, nigh-unconscious servants fell on the ground twitching,  mewling and drooling.

"E-Eh... We've been... bamboozled..." Lady Avalon hiccuped as she spoke, looking at you.

"Thoroughly tricked," Miss Avalon agreed, curling up a little. "M'ass hurts..."

"But it hurts... so good~!" Lady Avalon mewled.

"Y-Yeah... ngh..."

You chuckled.

"S-So... who... who has," Lady Avalon gulped, "the best, ass~?"

"It's, it's me, r-right?" Miss Avalon responded. "I... I have, the advantage..!"

You hummed, stroking your chin. "I don't know, I think I'll need another round of testing."

The two representatives of Avalon looked at each other. There was still a competitive spirit burning between them. Well then...

The two barely managed to raise their butts, offering them to you for another round of testing. You only waited another moment to make sure you were recovered, and then went back to the competition. Many, many rounds, matching them ass to ass, would ensue, until a winner could be picked.
