Hotel Chaldea Ep. Ishtar & Tohsaka Rin

"There will be those who look down upon you for the condition of not being a magus," Waver spoke.

"Should I send them to the Shadow Realm?" Mana responded.

"We'll keep that option open, but for now, let's just move on," you responded. "Lead the way to her lab if you would, Mr. Velvet."

"Certainly."

The Clock Tower could be as complicated or as straightforward as it wanted to be, though luckily, being there with a servant meant that even the most die hard and stupidly xenophobic of magi kept their distance and stayed back from the height of their annoyance. Made a short trip to the meeting point.

"Hey, is that the eastern magus over there? The hell's she wearing?"

Technically, you were there with two servants. One was yours, that being Mana, she of the Dark Magic and children's card games, and the other was Ritsuka's, Ishtar, an ancient Sumerian Goddess who happened to, indeed, be wearing a mortal's body as a vessel. That very same mortal would be the one that you would be meeting soon, as you passed a few entirely unsubtle onlookers whose gazes were locked onto Ishtar's ass.

"Damn, I knew she had one hell of a fine ass but sheesh."

The lesser scum, those who thought themselves important purely for their blood and who had no achievements of their own, could be found schmoozing in their natural habitat.

You paid little heed to them and shortly found yourself being shown the way to probably the least well organized and most chaotic lab you'd seen since that time Medea forgot that she was no longer immune to all poisons including alcohol.

You didn't really waste time, and after Waver, friend of Chaldea by way of being one of the few people you'd ever met who could get along with his alternate self, left, you went in. The laboratory was really more of a combination dorm room, study, laboratory and kitchen, and it was an absolute disaster.

"I'll stay outside and make sure you're not disturbed," Mana said, waving her hand, "go get'er, master!" she said, smiling and closing the door behind her.

The concentrated scent of woman was present in the room.

"I can't believe I'm forced to come here," Ishtar complained. "There's so many more important things I could be doing, you know?"

"Like counting your ever dwindling stash of gemstones?" you quipped. "Come on now, you're the one that jumped at the chance to meet your vessel."

"I'm here to protect you because you sent literally every other servant in your employ away at the same time," Ishtar complained.

About a few moments later, an absolutely identical woman came out from hiding.

"I guess I can't really hide anymore," the woman said. She had a slight accent still, but it was clear she'd been living in the UK for quite some time already. She looked very slightly older than Ishtar, probably in her mid twenties, and had green eyes to Ishtar's red.

Other than that, though, they were absolutely identical physically, and it would be hard to pick them off of each other, if it weren't for the fact that Ishtar was basically wearing what could only be described as fancy themed lingerie, and the young woman was wearing a respectable red long sleeved turtleneck shirt, thigh highs and a miniskirt.

"Fine, you're the Debt Collector aren't you?" she asked. "I knew this day would come."

"You borrowed a lot of money," you said, "miss Tohsaka."

She crossed her arms under her chest. "Yeah, I needed it for my research," she said. "So you've come to collect, huh?" she asked. "What's that gonna be like? If you're here to kidnap me or something..." she looked at the woman who looked identical to her. "I take it this is Ishtar?" she asked.

"You're not freaking out about someone who looks exactly like you," you said.

"I'm informed," Rin responded.

"Right the one bit of enjoyment I would've gotten here, seeing you freak out, is now ruined, thank you very much, you get no points, this vacation sucks," Ishtar huffed. "Right if you know how fucked you are can we just get this over with?"

"Not so fast," Rin said, "how about a counter offer?"

Ishtar wasn't surprised, not surprising considering she had access to the woman's own brain so she had something of an idea of what she was like. "If you're gonna try to bribe me with gemstones," she said, "I-"

"No, not you, I'm talking to you, Collector," Rin said, smirking. "I know you're a man of... particular tastes," she said.

"I'm very happily married," you pointed out.

"Hasn't stopped you before," Ishtar quipped, sticking her butt out.

"That's irrelevant," you said, "the point is that if I wanted sex, I could have it, even with someone who looks just like you."

Ishtar raised an eyebrow and looked at you. "You think I'm that easy?" she asked. "What if I said no, huh?"

"Not now, can you just cooperate for five minutes?"

Rin cleared her throat. "Yeah, about that," she said, "look, I'll level with you. I'm THIS close to finishing a project that will allow me to utilize the second magic, I just need the world to cooperate," she said, "and if you let me finish-"

"The second magic, the Kaleidoscope right? That allows movement between spaces and dimensions, it's similar to what we use," you noted, trying to recall the lessons on the topic, but mostly drawing blanks since esoteric high tier magecraft was difficult to understand even for magi themselves.

"Yes, but it also allows access to other worlds to extract energy as well - it's going to be very useful to Chaldea, but," she said, "it's just not possible for a human to do it," she said, "at least, not for a modern human like me," she said.

"Not possible for a human," you mused, "that means it's possible for a non human."

"Precisely, it'd be possible for, say..." she looked at Ishtar.

"What?" Ishtar asked, flicking her right pigtail behind her shoulder. "What're you looking at me for?"

"Well, what I'm saying is that it's be possible if I could establish a link with you and use your divine authority to reach past and beyond normal space," she said, bringing her hands together. "With that power, it'd be a cinch for me to pay off my debts and even export my services to Chaldea. So!" she said, "how about it, Collector?"

"Greedy to the end, anything if it'll get you out of paying, huh? I swear every version of you I meet is just as stingy," Ishtar stated. "Come on now, let's take her into Chaldea and-"

"Sounds good to me," you said, if only because you knew it annoyed Ishtar and that was always fun, "how do we do it?"

"Well, I've studied this topic quite a lot," Rin said, "and I need to basically create a sympathetic two way connection between her and myself," she said, "and," she seemed more than a little annoyed, "that means we need to have sex," she said.

"Because of course you do, that's what it's all about isn't it?" Ishtar quipped. "What, your boytoy not paying any attention to you?"

Rin turned on Ishtar and put a finger on her chest, pushing her back a little. "You shut up!" she said, glaring into the goddess' eyes with fearless energy and fierce strength.

"I don't think that's the case," you said, "look at her, she's drop dead sexy, I imagine you gotta watch out whenever you bend over."

"You think she's not aware she's flashing everyone with a skirt that short?" Ishtar noted. "This girl's way more of a slut than she lets on."

"No way, I'm just a normal person," Rin denied.

"Bullshit!" Ishtar said. "You think we're so well matched by coincidence? Hell no, this girl's just as much of a sex fiend as I am," she said, raising her arms and striking a pose to show her body off. "Look at this, her body is super content whenever I show it off, and believe me, her ass was super developed before I even took over this body, she's been using it to masturbate since she learned how to do it!"

"N-No I haven't!" Rin said, shaking her head. "There's absolutely no way-"

"You think? I guarantee if you stick a finger up her ass you'll find a clean butthole ready for sex," Ishtar said.

"N-No way," Rin said, her cheeks dusted red, crossing her arms and turning around, "stop that nonsense!"

Raising an eyebrow, you thought for a few moments, and then grabbed at her skirt, flipping it to reveal her cheeks.

"H-Hey!"

She was wearing a rather comfortable and practical pair of red panties, and as if by instinct, her body moved, her upper body moving forward and her hips pushing her butt out, as you grabbed at her underwear and pulled it off by the waistband, to reveal that you would, in fact, not have been able to put your finger up her rear.

"Is that a jeweled buttplug?"

"It's a really convenient way to carry a mystic code!" Rin said, her voice shaky.

"And it also feels really really good to walk around with a vibrating plug up my ass," Ishtar said, her voice pitching down slightly to match Rin's more perfectly. "I would know, I've got your own defenseless, vulnerable anus and damn does this body love when it gets played with!"

"Ugh! Fine! I like anal, there, content?" Rin said. "Can we do the linking ritual now?" she asked.

You hummed. "What do we do?" you asked, as your hand reached for her plug and began to toy with it, before pulling it out, leaving her gaping, winking butthole behind.

"L-Look it's simple," she said, "you just need to have anal sex with us simultaneously," she said.

"With his... one penis?" Ishtar asked.

"No worries," you said, "this is not the weirdest thing I'm prepared for," you said, reaching for the amulet Medea had given you so long ago now, and activating some of the spells engraved into it. Your crotch felt tight, your underwear too small, and your pants inadequate, within moments, you were forced to open your fly and let them drop and pull your underwear down.

There were two cocks, already starting to become erect thanks to the erotic and silly display Rin had put on and Ishtar's very sexy presence.

"How fucking perverted is your wife to put that on a permanent toggleable effect on a talisman?" Ishtar said.

"Woah, so that's- that's Age of the Gods level magic..." Rin said. "It's seamless and perfect, could I-"

"Sex now, study later," you said. "You got a bed here?"

Rin snapped her fingers and a bounded field dropped, revealing that what you thought was a pile of unidentifiable garbage was actually a protective illusion hiding a bed. Naturally, it was ready to go.

Ishtar smirked and before Rin could get up she moved swiftly, her arms blurring into motion and rapidly divesting her nigh-identical vessel of her clothes, stripping her and adding to the very real messes elsewhere before pushing Rin onto the bed, landing on top of her. Ishtar's clothes vanished into motes of light as she landed herself, and she held Rin down.

You looked at them, as they pressed their bodies together.

"You're real enthusiastic all of a sudden," Rin protested.

"I'm about to get my ass reamed," Ishtar said, "at this point you could be Ereshkigal and I still wouldn't give a shit as long as I get that cock all the way to the back of my throat from the wrong side."

"You're a disgusting perverted bitch did you know that?" Rin said.

"Oh, please, like you're not hoping against hope that he's gonna finally scratch that itch. You're still reeling from the one that got away, huh?" she said, looking into Rin's green eyes.

Rin glared at her.

You chuckled and moved between them, your fingers going to each of their asses, between their sweet cheeks, you found the right holes and began toying with them with your finger. Identical and perfectly vulnerable holes greeted you, this part at least was exactly the same for both of them, their buttholes offered no resistance, though the pressure at the entrance was significant, it was taking you in, deeper.

You played with their assholes first with one finger, twisting and rotating it as it went past the tight ring of muscle of their anuses, then you joined in with a second finger on each hand, curling your fingers down to scratch at Rin's weak spot, and curling your fingers up to scratch the same spot on Ishtar's body.

Both of them mewled and moaned in pleasure. There was friction, resistance, but also a wet and slightly slimy sensation, from Rin's asshole. She had clearly lubed herself up when she put the plug in, and she was using Chaldea branded stuff or better, because it was high quality stuff.

Perhaps in the first difference you'd noted so far, Ishtar didn't need any outside lubricant, her ass, magically empowered, produced all the lubrication it needed by itself.

"L-Look, I need you to make sure we cum at the same time," Rin said, "everything else we can take care of once the tantric ritual is finished. And you, you just need to cooperate for me to act in your name."

Ishtar laughed. "I'm interested now, let me see what you can do," she said, clutching Rin's face and forcing her to look up before coming down and sharing a wet and sloppy kiss with her, the two looking like twins.

Your cock, cocks really, twitched at the display, and you moved them, twisting your body as well to make sure the two cocks could go into the correct butthole. It was more difficult than fucking their pussies and you had to adjust how their pelvises sat against one another, and as you did, their pussies came into contact in very lewd missionary position tribadism that had both of them gushing cunt juices already.

Yep, definitely extremely compatible at a fundamental level.

Still, you wasted no further time, pressing the tips of your dicks against each of their buttholes, and instantly you were taken in, swallowed on both ends, finding yourself rapidly pushing until your crotch was against their asses and you felt their ass cheeks pressing against you, like pillows as you pushed into them.

Gasping for air, you found that the doubled pleasure was a BIG mistake. Their asses were not the same, they were close, but each difference was magnified a thousand times by the sensitivity your cocks were rapidly gaining as they were stuck in the molten hell of pleasure that was Rin's defenseless asshole and Ishtar's vulnerable asshole.

Rin was... pristine, for lack of a better term. She had only toyed with her ass, and you could immediately tell that it was ecstatic to finally have a real cock to wrap around and squeeze. She panted and moaned and lewdly kissed Ishtar as the pleasure overwhelmed her, and her asshole twitched and wrapped around you, squeezing you with a mismatched rhythm that tried its hardest but demonstrated inexperience.

Meanwhile, Ishtar was a well matured and thoroughly educated asshole, taking Rin's already extensive natural talent for anal and combining it with the boundless sluttery of the goddess Ishtar. Her remarkable asshole was twitching and shaking and squeezing in exactly the right rhythm to match your heartbeat, making sure to squeeze when the blood was rushing through and your cock was twitching to its maximum size.

Both of them felt so different, yet the inside, the texture, the folds and creases within those lovely anal passages... they were the same.

Bringing your determination together, you put it all into your movement, sitting on the bed in a weird way that allowed you to thrust into the two assholes simultaneously, your legs forward and your knees bent such that it looked like really weird and odd three way tribadism rather than proper sex, but it worked out just well enough that you could support your weight on your hands and thrust pushing off of the bed.

Their kiss broke with a loud and wet smack and within moments both of them were moaning.

No matter how much experience they had or didn't have, no matter what they were doing or trying to do, at a fundamental and singular level, they both shared the deadly weakness of a powerless, defenseless asshole that begged for cock.

You found yourself starting to lose sound reasoning in the face of some of the best asses that anyone could ever dream of fucking, from the shape of her fat cheeks to the almost inhumanly sexy voices that came from the two as they found themselves losing to their desire, clinging to each other-

Their orgasm caught you by surprise. Despite all the differences, they came at exactly the same time, with exactly the same overwhelming intensity, and they squeezed and strangled your cock in exactly the same way for each of them, with perfect synchronicity that pushed you over the limit, the intense pleasure pushing you over the limit.

The next thing you knew, you were exploding.

The effect that duplicated your cock also multiplied your ejaculations, making you cum about four times as much as usual, and even the very flexible and talented assholes that were technically both Rin's asshole couuldn't contain the massive loads of semen that you dumped into their bowels, filling them up within moments and overfilling them.

Both of them looked pleased beyond control, their faces identical open mouth smiles, their eyes almost rolling up, their modest chests pressed against one another, their bodies twitching in unison as they enjoyed the feel of getting thick hot babymaking cream up their buttholes.

It took a good few moments for you to finish coming and then relax, almost dropping back onto the bed, panting.

"Did it work?" you asked, pushing yourself up.

"I- ergh, I..."

"She totally forgot about it," Ishtar said. "We're gonna have to go again. Oh the horror," she said, all deadpan-like.

Rin's face was red. "I'll get it right this time!" she said, not even denying it.

She wouldn't get it right the second, third, fourth or fifth time.

Mana had to come in and help before she finally got the ritual right, and it didn't even work.

Needless to say, she had a long road ahead of her to pay off her debts...
