Sex marathon contest!

...you know, if she DOES have the ability to mimic your angelic form, you could enter a shapeshifting contest just for fun, and maybe to beat 'em at their own game.
The changeling, being both Fey and a natural shapeshifter, could outlast you, no matter how well you do.
That's the point, Angel transformations are obviously exhausting, and no matter who is drained first, their true form will be revealed.

Grow a ludicrously large dong. They'll either panic at what they're expected to take or break their glamour trying to. Cecil can judge the results.

Cecil has an entire collection of sex toys. Have a 'will it fit' contest.

She must be the leader of the trio.

While they might be able to mimic your form, they might have difficulties with the physical aspects you've specifically trained in under Argus.

They're ultimately a creature with rigid-ish chitinous plates, meaning they aren't as flexible as you are. So lets say, twisting your body into a kinky pose that would make a circus acrobat impressed might give it pause or discomfort.

In other words, see if it can mimic one of your 'impossible without shapeshifting' poses.

“Woah, you really did your homework.” The twinned mice crane to look at one another, trying to spot any inaccuracies. “You even got my outfit right. You must have been spying on us all day.”

“You’re one to talk. You're way more convincing than the other one…”

“Well, how about this?” One of the Caseys ignites her angelic form and nods as though declaring checkmate. “Can your glamour do this?”

“It’s not a glamour!” Her own aura roars to life as a pair of wings spread behind her. “It’s my angel form! What about this: my binding spells?”

A binding ring forms around one of the Casey’s arm. “Are you kidding? We both know fae basically invented binding magic. That would be easy to fake.”

“I’m Casey!”
“No I’m Kacey!”

“Mmm, quite a conundrum…” The bird taps his beak as the two square off and glare at one another.

Okay, you've got her on the ropes. Now trick her into doing something you can't do, like enhancing knockers!

Perhaps hot lesbian mouse clone sex is what is needed here, judged by Mr. Ochre. See if Casey can eat Changeling pussy with a shapeshifting tongue, tail, and other unnatural anatomy bending a chitinous bug might not be ready to replicate with a mere glamour.

Might be wise to bring all this commotion inside though, lest agents of the court see whats going on. Somewhere with toys to play and test with.

Two shapeshifters, Technically only one SHOULD have a genuine Angel's Essence but even if it grants powers other than shapeshifting, they ain't something that Casey knows. Given that Angels are Life Elementals, as well as the first Fey... not easily shown off, either.

Casey DOES know about the other changeling, and the real Casey would never throw someone else under the bus, even a theoretical enemy, but the kind of Fey who would plan this? They would.
Not that I know what to do with this right now, but it IS there. Perhaps see how she reacts to us mentioning the other, a personallity is both hard to replicate, yet easily noticed if you fail.

...not sure you can just bribe her with the prophecy, I feel she would demand payment if not revealed first, in the form of the Aegis.

Well, there are still the *Countless* way you two can exhaust each other.

Cecil has spent enough intimate time with Casey to know where to touch her and the reaction the real one would give.

>>1129931
Technically we could just delay until Gabe or Kol gets here... with snacks.

I mean, Cecil was *there* when Casey got her wings initially. It's not just her angel form, she got them from his husband.

Kacey really chose her timing well, because anything Casey learned under Argus (that Kacey wouldn't know), Mr Ochre would't know either.

Ochre's private chambers, where his 'Joy' is, is specifically designed to be unscryable. The Changeling would have no way of knowing what happened in that room.

So, Cecil asking what happened in there, before today (in case he suspects Casey was an imposter when the mice first arrived today), would sus out the Changeling.

Changeling wouldn't know about the ghost haunting his favorite dildo, for example, or why it was doing that.

“Wait! Cecil, there’s one way to figure this out: you can disrupt a changeling’s glamour with an orgasm!”

“Hah! You think that scares me? You’ve just revealed your own weakness!”

“Oh, my. I’ve been on enough adventures to figure it would come down to this.” Mr. Ochre reaches into a pocket and pulls out a small bell. Ringing it summons one of his butlers, who leans down politely to listen to Cecil’s murmured request.

The servant departs and the bird turns to address the identical mice. “Sounds like we can sort this all out fairly quickly. I’m going to give the both of you a chance to opt out, rather than be unmasked.” Cecil explains.

“I’m in.” One of the pair declares, slipping out of her pants.

“Same here.” The other says, following suit.

“Oh really, you sound awfully confident~” the first one teases as she strips out of her bodysuit.

“So do you~” replies the other, taking off hers, revealing an identical body: right down to the creator’s mana brand.

“Since we’re all in agreement...” Mr. Ochre nods as the servant returns. He sets down a silver tray laden with pieces from Cecil’s collection, as well as lube. Another servant unrolls a pair of long, thin, foam mats under the gazebo. “Both of you may use whatever you want to prove that you’re not a changeling. I believe I’ll leave the rest up to you.”

You know, if it had been like, flashing feathers mana brand, this would be so much easier, mana I imagine would not be so easily replicated, even if the look and function of the brand can be replicated.

Alas, you cannot check against the source for this one, now can you?
(well you could, if Gabe still has some leftover essence, but at this point you don't care, do you)

Leave the big one to the changeling; Mr Ochre doesn't yet know what exactly you learned from Argus.

I suspect this Changeling is so absorbed in her role that she can't remember being a Changeling anymore.
One issue here is that orgasms can be faked. So, solo play isn't much evidence at all... especially if the changeling has some kink that's required for her to get off. So for this test to work, the contestants have to be able to challenge eachother.

Casey: see if you can spot the changeling's eyes lingering on a specific sex toy. Challenge them to use whatever you think is their favorite. It's also possible that she's absorbed enough in her role that she would get off most using whatever you would like most...

Is it just me or does one of the Casey's halo of eyes have one less eye than the other? Assuming the eyes are at all consistent / not biblically shifting.

It would be quite the surprise if the Changeling actively hypnotized herself (or used some other form of magic) to completely fill out her role down to her own beliefs.

Potential tactics:

1) Use the toys to recreate statue scenes Casey had with Argus. The changeling might have 'studied' them laboriously but could never feel the real deal - being put in that artistic position might tip them over the edge, as would watching it unfold live.

2) Turn the dildo usage into an art performance for the changeling (and Ochre) - describe how it feels going in for the other in copious, verbose detail.

3) Take turns inserting increasingly larger dildos while the servants / Ochre trigger vibrators if there is any sign of slowing down or hesitation.

…Femdom battle?

The pair approach the tray and assess their options. One takes the lube and a large, equine dildo.

“Oh? Going big, are we?” Says the other. "You really need all that lube?"

“Didn’t your research tell you?” The first says, dribbling a layer of clear, sticky fluid over the shaft. “-That I love anal?”

“I don’t know, if I’d say ‘love’…” the other says, picking up a much more modest dildo and a buttplug. “I like it about as much as vaginal, it just depends on how I’m feeling. Do you fey somehow think that I’m a size queen?”

“No…” says the first, positioning herself over the silicone cock. She slips the thick, broad tip inside and slides down a few inches. “Ah~ Just showing off what this form can take, to prove I’m real.”

The other Casey slips the buttplug into place and activates the vibration charm on it. Kneeling down, she positions the dildo beneath her and starts riding. “Ah~ we’re both shapeshifters: that doesn’t prove anything. The goal is just to get off. Right?”

“Except you’re not a real shapeshifter, you’re just using a glamour. Unless you actually have an angel form, something that seems extremely unlikely, you’re still bound by your physical limits. As for me: Argus showed me that taking something like this is easy, once you know how to adapt.” She says, dropping herself onto the shaft and bobbing there for a moment as her angelic form adjusts to the penetration. “Ahhh, fuck!”

>>1130089
Hmm, she could prove that even more by sticking multiple toys in. Eventually. Does that accomplish anything though? Proving someone is using a glamour isn't the same as breaking it, is it?

Needing lube for the large dildo is already a sign of some limitation.

Casey also has something the changeling likely doesn't, a prehensile AND shapeshifting-capable tail that can fit into all sorts of nooks and crannies!

Unless the fey insect can fake it with binding magic tentacles, the glamour, OR also has a prehensile, tactile tail (only thing I can think of being similar is a scorpion stinger, which would be too dangerous to use for kinky stuff in a thieving masquerade), Casey can tease the fey with her tail and they can't retaliate.

It's probably nothing, but. One of them appears to have an odd number of eyes on their halo, while the other has even.

>>1130089
Huh, what's up with the end of the right one's tail?

>>1130096
Angelic form Casey has a Jerboa-like tuft at the end of her tail. You can see it during her fun with Fennel.

>>1130094
I noticed that as well. Could be an actual irregularity/mistake by the Changeling, or it might just be the way the halo is drawn, if the eyes on her halo move / rotate around due to being Biblically Accurate.

If she produces more irregularities as she gets hornier, it might mean she's having trouble holding the glamour.

A duet of squeaks and moans fill the gazebo. The twinned Caseys bounce and grind in place, trying to drive themselves towards climax. Watching one another for any signs of a dispelled glamour, the mice synchronize in an odd display of mirrored lewdness.

Casey, the real one, thinks to herself: “What’s her game? Its not like I have a glamour to dispel, she can only lose if this goes on…”

Realizing she’s too distracted to cum properly, Casey lets her mind drift back to her month of training. Dropping onto all fours, she uses a ring binding to hold the thick dildo in place before thrusting it into herself.

Positioned to watch her doppelgänger, Casey looks on with a growing sense of arousal. As her counterpart rolls her hips into the faux cock, the mouse thinks of her many trips to Argus’s gallery: countless hours staring at her own gorgeous, angelic body, frozen in the moment of climax and worship of her then master.

“Ahh-haaah~!” Her hips buck back into the massive dildo as a small orgasm shivers through her. Cecil raises an eyebrow, but Casey keeps going, building up for a larger, more powerful finish.

Hmm, maybe the Changeling is counting on Casey to cum so she can overpower her with a binding.

Or she's planning to cast a glamour onto Casey to make her look like a Changeling as she cums, in other words, framing her and fully 'replacing' the original...

Or maybe we're listening to the Changeling right now, who's so deep in the role she genuinely thinks she's the real deal.

>>1130150
Maybe she's just so confident in her ability to keep her glamour up that she expects this contest to end with no obvious loser? Or she's going to fake an orgasm, and accuse you of faking one, so there's no loser regardless?
Or this is buying for time while she thinks the other two changelings will manage to steal the aegis somehow.

huh, did Casey tell the changeling yet about the prophecy?

>>1130150
...are we sure that the changelings planned to win?
The first two... didn't seem to try that hard. Hey wait what does winning even mean here. what even was their game plan, fuck the shield out of us or the people around us? Did the changeling just know that we use sex to win at life and did so blindly?

...either the changelings are as much goofy goobers as our mice sometimes are, which at least two of them are (and if caught in her own glamour, the third definitely is), or one of them knows about the prophecy, and wants in on it.

>>1130173
To be fair, the Casey changeling could have gone into this purely to have sex and/or is a massive pervert/nympho (or a literal 'nymph' in bug term), the Aegis just being a fey-appropriate excuse.

And given how many other Fey enjoyed the gallery (and sent the mice booby-trapped gifts), if they're the equivalent of a '#1 fangirl' who's obssessed with them... Well, imitation is the sincerest form of flattery, and this scheme is in fact a stroke of genius when it comes to arranging to have sex with your idol and/or become their sex pet.

you guys I think we just have to accept that there are two Caseies now

The competitive masturbation goes on as each mouse works to prove her trustworthiness. Their voices ratchet up in desperation, riding harder and faster on Cecil’s toys.

“Ah! Ah~ ah! Oh- oh ffffffuck!” Casey feels her transformed body lock up and shiver. She watches as her opponent bucks her hips frantically and drops herself hilt-deep onto the phallus. Seeing herself climax from the outside triggers something in the mouse and she tips over the edge a moment later.

Together the twin Caseys ride out gasping, shuddering orgasms: staining the soft workout mats with drops of lightly glowing cum.

Casey flops forward, letting the dildo slip out of her and land on the ground. She looks over at the changeling: who's oddly unchanged and still clad in her glamour. “Hey, what gives? You’re still me?”

“You mean, you’re still me!” Says Kasey, dislodging the humming buttplug and sighing.

“Hmm, a conundrum.” Cecil says, having watched the pair from behind an impartial mask. “It seems that one of you is either quite skilled at faking an orgasm, or has much better control of her glamour than expected. It seems another test is in order: one that’s much harder to cheat.”

The bird coughs and looks to the sky before asking, "Dear, would you give us a hand?"

Ah yeah, it would be hard to fake a deity's personal blessing.

Damn she's good. But she might actually be a little too good? When casey gets lost in her angel form, she actually loses her markings but the doppleganger appears to still have them? It's flimsy evidence but at least it's something?

Maybe flashing feathers can help?

The changeling wouldn't know how Casey originally got her wings. I wonder if we could catch her on that.

Hmm, the fact Casey's cum is glowing with angelic energy should a tell, doubt a glamour can fake that.

Also, changelings react quite vicariously to said angel energy. Have the changeling taste some mouse-angel cum and see if they react strongly.

That, or I suppose Flashing Feathers could give both a ride / taste test.

I wonder if the entire point of the contest was simply to stall for time for Flashing Feathers to show up.

>>1130255
All part Mr. Ochre's scheme to have a truly debaucherous foursome as a gift for Flashing Feathers. Just. As. Planned.

A god fucking both Caseys with their double dick to determine which one is faking the orgasm or by fucking both so thoroughly to reveal the changeling when they lose all composure sounds like a completely valid and rational idea

There’s a rainbow colored blur as the coatl drops from the sky and lands between the panting mice. Two lovely, blue cocks emerge from his slit, ready and eager for attention. “Oh, how wonderful: two blessing bearers! You are both looking quite lovely~ I see that you’ve incorporated the gift of my feathers into your new form.”

“I’m not sure how long it’ll last, but it was an honor to carry your favor into battle, Flashing Feathers.” Casey replies with a slight bow. “Too bad we were defeated. We gave it a good shot, though.”

“Mmm, I missed your presence, but am glad you were able to use my gift to steal the aegis. I assume that the reason there are two of you is related to that?”

“Of course. We need you to find out which is the real Casey.” The mouse leans close and caresses one of the wind god’s cocks. She looks to her doppelgänger and dares her, “Right? Well, are you in?”

“Sure!” Kasey shoots back. The initial shock at the arrival of Flashing Feathers wore off quickly, and she eyes the coatl with a calculating expression. “Why wouldn’t I be?”

“You can still back out~” Casey teases, kneeling before the snake god and kissing his lower shaft.

“I don’t know what you’re talking about out.” The clone kneels next to her and joins in, “You just better make room, okay?”

>>1130391
Right, if the Changeling absorbs his mana, that will definitely break her concentration. Also I imagine Casey cannot receive the Blessing a second time, while the Changeling can. Benefit of the contest, I suppose! It'll help with the disguise, too... unless she can already fly?

Could dare the Changeling to gulp down both divine dicks at once. Casey can handle it with her training.

While Flashing Feathers and Mr.Ochre are here, might be worth asking them what the deal with 'prophecies' are, in case they know more about those.

It seems a bit nasty that people with access to oracles can just announce the future or that fate is that 'rigid' (do bad things happen if you try to prevent a prophecy or do nothing to fulfill it?).

Casey eyes her counterpart, as she bobs her head on the lower shaft. The combined fellatio works up the elemental until his head rolls back and he hisses eagerly.

“Yesss, ah~ You work together well. What luck to have the gift of my blessing repaid upon me twofold…” Flashing Feathers moans.

The tingle of mana-laden pre-cum lands on Casey’s tongue and she grins to herself. ”There it is. You might be able to fake your way through an orgasm, but let’s see you handle a load of an elemental's cum~”

She pulls off Flashing Feathers’ dick and looks up to the gleaming feathered serpent. Casey pumps her hand up and down the shaft, keeping him nice and hard as she shakes her tail invitingly. “Well, my deity: your herald has returned and desires your blessing. Are you going to keep her waiting?”

“Mmm, very good. Yes. Let me welcome you home, my Blessing Bearer~” A long wingtip twirls in a little circle and the mouse smile, turning around for him and presenting herself. A long month of Argus’s training keeps the mouse ready and patient, looking straight forward until he takes her.

A sudden weight drops onto Casey’s back and she smirks as her doppelganger takes the bait. “Oh no you don’t! Don’t even think of leaving me out! I’m the real Blessing Bearer~” Kasey leans forward, straddling her twin and presenting herself as well.

”That’s it, stay eager to prove yourself. Your little mask won't hold up much longer.” Casey says to herself as Flashing Feathers lines himself up with the two mice.

Casey and Kasey are orbiting ever closer to just fucking each other.
Casey could flip over to kiss her and get that started!

Hmm, what if the twist is that the final Changeling WANTS the blessing/Flashing Feathers mana-cum?

Or isn't a Changeling but something/someone else (a mortal, maybe, in disguise? A Fey Court agent?). One that managed to trick her 'Hive' or was accepted as their member.
