Cadance and Chrysalis have a simple challenge for Shining Armor: Can he tell which one is which?

Cadance and a 'reformed' Chrysalis have a simple challenge for Shining Armor: How well does he know his wife? Can he tell which one is which? They dare him to take a very close look at each of them ... and then fuck the real Cadance.

Under the pressure of a test this risky and risqué, Shining Armor will have to give it everything he's got. Getting it wrong is unacceptable ... and so is admitting he can't tell the difference at all. (Of course, admitting that he wants nothing more than both of them at the same time ... that's out of the question, isn't it?)

Contains: blowjob sandwich, sex, teasing, infidelity, implied homosexuality, implied incest, spanking.

Choose Wisely

Shining Armor settled for a stately – but brisk – walk through the Crystal Castle's corridors, even though the itching anticipation inside him should have goaded him into a flat-out run. But he couldn't do things like that now. He was a prince, and he had to act dignified at all times ... at least in public. If the crystal ponies saw him sprinting through the halls, they would think there was some kind of national emergency going on, and that would be no end of trouble.

...When the only real 'emergency' was back in his and Cadance's private bedchamber.

Today was their anniversary. Not the anniversary of their marriage – that was a dreary and formal affair of state celebrations and banquets in their honor. No, this was the anniversary of when they'd first started dating, a time for just the two of them to be together, to enjoy each other.

Or, at least it usually was. But everything had gone wrong today when Cadance said she had to meet with somepony in a secret royal summit – and he wasn't even invited to that! He hadn't seen his wife since this morning! She had only been able to assuage him by promising that when the summit was over, they would go straight to their bedroom ... and that he would definitely, definitely, like what he found there.

The anticipation roiled in him so much he hadn't even minded playing babysitter for the two-year-old Flurry Heart. She was a the little terror of the castle, and they would normally have scheduled a sitter for the whole of their special day together ... but since he had the day off and she would be busy, she had suggested that he spend some much-needed quality time with their little daughter. He didn't mind, really. It was difficult, though, after the first few hours. When the time came, he couldn't wait to give her over to their favorite babysitter and make a beeline for his bedchambers.

He couldn't wait to find out what special treat Cadance had in store for him. Being married to the Princess of Love had its perks, after all.

And there it was: the door that had been fading in and out of his daydreams all day long. No guards today ... because sound carried in these crystal walls, and Cadance felt self-conscious if she knew there were guards listening in, no matter how professional and tight-lipped they were. He found himself breathless as he finally faced that door, so he took a few moments to calm himself down, taking deep, deliberate breaths and trying to forcibly relax his muscles. It maybe helped a little bit.

Unable to wait any longer, he twisted the latch with his magic and burst inside.

He had expected perhaps something like Cadance lounging on the bed in gorgeously frilly lingerie, or maybe with an array of new sex toys spread around her. Maybe even something truly outrageous, like finding her tied down and gagged, waiting for him to use her in any way he pleased...

There was no way he could have expected what actually he found: Two Cadances stood side by side in front of the bed, their outspread wings intermingling feathers. Each of them gave him a shy but sultry smile as he numbly closed the door behind himself. They came even closer together as they walked toward him, and in eerie unison, they said, “I've been waiting for you, Hubby. Ready to play a little game?”

He didn’t manage to get his mouth or limbs to work just yet, but his brain was working furiously. He'd managed to get through most of the disbelief, denial, and pure shock. Now he was starting to struggle through the 'why' and the 'how'. His eyes glanced between the two of them. “C-Cadance...?” He had no idea how he'd intended to finish that question, not that he had any real ability to.

The two of them stopped right in front of him. “Well, Honey,” one said. “What do you think?” the other finished.

“I... I...” He blinked repeatedly, his mind still doing cartwheels. But then it clicked, snapping into focus. Of course! He jumped back from them. “Chrysalis! Get away from her, Cadance!”

They both obliged him, jumping away from each other. One giggled, which got the other going. When they'd calmed down a little, they smiled at him. “See, I told you he was quick on the uptake.” “No, I was the one who told you!” Both of them giggled again at their subterfuge.

“Cadance...” He still didn't know which of them to look at when he spoke to her, so he ended up glancing back and forth between the two. “What's going on here? Which one is the real you?”

“Well now, isn't that an interesting question?” They both came toward him, sidling up to either side, each of them almost touching him ... but not quite. “Why don't you tell us which one is the real one?”

Shining Armor shuddered a little, knowing he must be standing so close to that monster, Chrysalis. Sure, he'd heard the reports from Ponyville. Twilight and her friends had succeeded in reforming yet another baddie, Chrysalis and her changelings were on Equestria's side now, everyone was full of the magic of friendship... He had his doubts. Those other ponies might be able to trust the Queen of the Changelings, but they hadn't experienced what it was like being brainwashed by her, having the most important pony in their life stolen from them and replaced with an emotionally vampiric monster. How could Cadance trust that wretched insect?

He was starting to feel claustrophobic with the two alicorns, one real and one false, closing in around him. “Cadance! Stop this right now! This is serious. What the hay is going on here?”

They both reached out hooves and stroked along his sides ... it made his fur stand on end, for more than one reason. They came in closer, whispering into his ears. “We're going to have a little test, a challenge for you.” “Can you tell which of us is the real Cadance?”

“Cadance, this isn't funny. How am I supposed to tell?”

From the way they giggled, they must not have shared his opinion about whether it was funny or not. “Look at us.” “Touch us.” Their words were whispered so close to his ears that their breath tickled the little hairs there. “Smell us.” “Taste us.”

He gulped. Was this room getting really hot all of the sudden, or was it just him?

“And when you've figured out which of us is real...” They smiled and winked at each other. “Get on her back and fuck her silly!”

“What? I can't do that! What if I get it wrong?”

They smiled sweetly. “Well, if you get it right, you'll be richly rewarded.” Then their smiles turned wicked. “Get it wrong, and you'll have to be punished.”

“Um... Ladies, I'm not sure I really want to do this kind of—”

“Oh, surely it can't be that difficult.” “You know your wife better than anypony, right?”

Celestia's teats, these mares had him in a bind! If he backed out of it, that would be as bad as admitting he couldn’t tell the difference ... and that would sure ruin the mood of the evening, wouldn’t it? He had to do it. That was okay, he was sure he could, if he really needed to. And the idea was growing on him ... two beautiful pink alicorns, one a love-goddess and one a sex-goddess. He could feel their hooves slowly caressing him, gradually becoming more bold in where they dared to touch him...

No! He had to focus if he was going to succeed. Okay, no problem. This should be easy. He'd led the unicorn guard in changeling detection drills a hundred times since the day of the wedding. If he could just—

One of the Cadances smacked his horn the moment it started to glow. The other one slapped his ass. “No magic!” they said as one.

Damn. So much for the easy way. Still, he could do this ... probably ... maybe. How would Twilight do it? He thought for a moment, which was a struggle in itself as the two mares went back to running their hooves over his body. He would need some way to keep track of them. “You.” He pointed to one at random, the one on his left. “You're Cadance One. And you–” he pointed to the other “–you're—”

“Hey, why does she get to be Cadance One?”

“...You're, um, 'Cadance A'.”

Cadance A quirked an eyebrow at him, but after a moment she shrugged it off. “All right then.”

The two of them moved in front of him. “So,” Cadance One asked, “which one of us is the real one?”

“Take your time and give us a good look,” Cadance A said. They stood side-by-side in front of him, watching him expectantly.

Okay, he told himself, I can do this. Maybe there is just some simple mistake in Chrysalis' disguise I'll be able to spot. I should at least try. The fact that he'd be able to ogle his wife in glorious double-vision had nothing to do with it. Nope, definitely not a factor in the decision-making process whatsoever.

He began by simply walking around them, looking at them very closely for the first time since he'd come into the room. He took in their long legs, the lustrous sheen of their manes, the cute little arches of their backs, the way their cutie marks curved over their deliciously compact rumps. But by the time he'd come full circle around them, he hadn't picked up the slightest clue of any changeling disguise. They were exactly identical, he could swear it. When he stood in front of them, he paused. “I, um...”

“Why don't you take another walk around?” “Take a closer look.”

“Um... Okay?” He started in the other direction, beginning with Cadance A this time. Looking even closer, he could see the faint whorls in her freshly-groomed fur, the delicate pattern of pink and purple feathers in her wings, the way her eyes glinted at him in amusement... As he came around behind them, though, both of them reacted.

They lifted their tails, arching them high and toward each other, letting them mingle together in the gap between the two ... in the gap between their two perfect royal butts. Shining Armor's walk froze in mid-step as he soaked in the sight of two gloriously identical pink pussies on lewd display just for him. The two Cadances leaned back a little, spreading their legs out slightly and presenting themselves.

He couldn't breathe. He knew his mouth was hanging open, but he couldn't summon the willpower to close it.

Both Cadances looked back and giggled at him ... and all he could do was stare at how their laughter made the soft skin of their nether lips move in and out just a tiny bit.

They were exactly identical. Over the years they'd been together, Shining Armor had gotten more than a passing familiarity with his wife's pussy. And now there were two of them, identical in every detail. Exactly the same petite size, and exactly the same slight upward pout that seemed so eager to catch every drop. They both even had that little spot that was slightly darker halfway down the left lip ... how closely must Chrysalis have had to examine Cadance to get this level of detail right? Was that what the two of them had been doing all day in their 'royal summit'?

“So...” Cadance One nodded her head suggestively toward her partner. “Have you figured out which one?”

He took a deep breath. This was nerve-wracking ... and undeniably arousing. He had to keep control of himself and ignore how he was beginning to slip out of his sheath. “It's ... it's a very good disguise. You two are exactly the same!”

Cadance A's pussy winked the moment he said that, flicking a glimpse of her vivid pink clit at him. Had she gotten pleasure from him complimenting the disguise? He decided to file that as one piece of evidence for Cadance A being the fake.

“Well, if you're not sure yet, I suppose you're just going to have to look closer,” Cadance One said. “Why don't you move on to touching? Your wife has been going without you all day.” She glanced meaningfully at Cadance A's pussy as it winked again. “I'm sure she would appreciate it.”

Wait? Was that why Cadance A was winking? Or maybe Cadance One was the real Cadance, which was why she was focused on her long day without him... Why did this have to be so hard?

He began circling them again, more slowly this time, and he hesitantly reached out to touch Cadance One along the gentle curve of her back. Her fur was soft and velvety, just like he'd felt hundreds of times before. But for all he knew, this was Chrysalis ... not that he hadn't touched her before, either. By reflex, he suppressed the memories of sleeping with 'Cadance' on the nights just before the wedding. It wasn't hard – those memories were fuzzy anyway.

There were more important things to pay attention to, like the supple feel of this Cadance's ass underneath his hoof. Firm and just a little yielding, it captivated him as he ran his hoof along the perfect round curve. The feel of it was exactly like he remembered...

Maybe the other Cadance would feel subtly different? He walked behind them both, trying not to pay any attention to how his cock began swinging free between his legs. Rearing up a little, he reached out with both front hooves and took a generous grab of each of the pretty pink asses in front of him.

Both Cadances gasped slightly at his touch, making his cock twitch.

He rubbed their lovely curves, kneading them firmly. He couldn’t take his eyes off the way it made the smooth skin of their pussies move and stretch a little. But both of them felt exactly the same – the same slight softness hiding firm muscle underneath. He wasn't any closer to identifying his wife.

“Still can't tell?” Both Cadances looked back at him with lust-filled eyes. “Maybe you should check inside ... maybe the disguise is only skin-deep.”

By now, he was sure the changeling's disguise would be perfect there, too ... but he couldn’t deny that he wanted to touch anyway. Moving over to Cadance A without letting go of her ass, he switched hooves and let the other one gingerly stroke across the perfect little slitted bulge of her pussy. His breath caught as she winked against his hoof, smearing a little wetness onto it. Growing bolder but still careful of his hard hoof against the soft flesh, he pressed against her, slid his hoof sideways a little, pulled one of her delicate pussy lips to the side to reveal the welcoming pink entrance. She was smooth and shimmering-wet inside ... exactly like his wife would be.

What about Cadance One, though?

Cadance A whimpered slightly when he stopped touching her, and she tried to follow him with her ass, right up until it bumped up against Cadance One's. Shining Armor winced at the idea that he might be neglecting his wife ... or was Cadance A actually Chrysalis, using this as a ploy to distract him from giving his wife the attention she deserved?

This was all too confusing, and it was really hard to think about anyway ... when he had the vision of two Cadance asses, each pressing up against the other in an attempt to get his attention.

He touched Cadance One's pussy, coming even closer to it, getting an up-close look at how the supple pink skin moved under his hoof. It wasn't only his hoof that moved her, though. As he touched her and stroked her slit with the softest part of his hoof, she let loose a frantic volley of winks. Her pussy convulsed under his hoof, leaking a trickle of crystal wetness, and her legs spread open a little wider as that little stream ran down her inner thigh.

Shining Armor's cock slapped against his belly, and he had to force himself to stop ... or he would have mounted her right that instant. No. He wasn't sure if this was the real Cadance – he couldn't allow himself to be tempted into mounting the wrong one. Maybe Cadance One was the changeling ... had that display of raw lust been meant to trick him into impulsively picking her?

Cadance would want him to pick the right one ... but Chrysalis? She would probably love nothing more than to disrupt their relationship by getting him to pick herself instead. He had to be careful.

Cadance A was visibly suffering from the lack of attention, and she flipped her tail into his face in order to get it back again. Well, they had said to test them by smell... He took a deep whiff of her tail. A mix of exotic flowers and something like bubblegum – the unmistakable scent of Cadance's favorite shampoo. Pulling his nose out of her tail, he grabbed Cadance One's and repeated. Her tail smelled exactly the same. Damn it all, had they been so thorough that they bathed Chrysalis in all of Cadance's favorite products, or did her transformation magic also cover smells?

Both Cadances backed up toward him, brushing their tails over each side of his back. They straightened and stood taller, thrusting their deliciously round rumps up toward his face. “Of course we shared all of my favorite bath treatments.” The other Cadance giggled. “You mean my favorite treatments. You should have been there, Hubby.” “It was a wonderful bath, wasn't it?” “The tub was a bit small for two, but we didn't mind getting a little close.”

Shining Armor's head swam with the vision of their asses, both of their perfect pussies in his face ... superimposed upon his imagination's feverish work on the bath scene they described.

He was touching himself, without having realized it. No! He had to keep his head in the game and his hooves off his cock if he was going to get through this. Focus on checking their smells... He leaned forward a little – it didn't take much after how close they'd come to him – and sniffed politely at Cadance A's pussy. She winked open for him as she felt his breath on her. Before he could get too distracted, he did the same with Cadance One.

Both of them smelled just the same, just like Cadance always did after a recent bath: clean and with just a barely perceptible hint of sour, lustful musk.

His brain was threatening to lose this for him, sending inappropriate thoughts coursing through him, thoughts of taking her that very moment, of marking her delicate mare-like scent with his masculine-smelling cock ... and smearing her with a healthy portion of his cum. Some primal part of him insisted on marking her as his own mare that very instant.

He forced himself not to do it.

“Still can't decide?” “Then I guess you'll have to taste us.” Both Cadances winked at the word 'taste'.

Shining Armor steeled himself. He knew they were right, that he still didn't have any clue which one was which. And taste was probably the hardest sense to fake, right? But ... was he ready to do that with Chrysalis ... again?

Cadance would have to forgive him. She was the one who had set all of this up, after all.

Trying to hold the distinctive taste of his wife in his mind, he leaned in and took a delicate lick along the smooth outer lips of Cadance One's pussy. His restraint didn't last long, though. When she winked open wide for him, he plunged his tongue in without thinking about it. It was an automatic reflex by now, and it left him lapping up a faceful of Cadance One's slit. The soft flesh pressed gently against either side of his tongue, sliding easily.

With Cadance One's tangy juices still coating his muzzle, he darted over to Cadance A and dove into her without hesitation. She winked in surprise and lust as his tongue slipped into her, and she moaned as Shining Armor took her winking clit into his mouth and gently suckled it.

There wasn't any change in the flavor. Shining Armor was dimly aware of that fact as he continued eating out Cadance A, listening to the wonderful little sounds she made, feeling the way her body tensed up and the way her pussy begged for more. He knew that he had just licked Chrysalis' pussy, that he might still be doing that ... but his cock was raging hard under his belly and he was starting not to care.

“Does the other me taste better?” Cadance One asked.

That snapped Shining Armor out of it. What if that was his wife asking that? Would she get jealous if he was giving Chrysalis all the attention? Her words didn't sound like something the changeling would say ... Chrysalis would be more likely to opt for something like tempting and enticing him, rather than an almost-jealous question. She would have no cause for jealousy.

So, did that mean Cadance One was the real Cadance? He pulled his damp muzzle out from under Cadance A's tail, and he took a step back so he could look at both of them. That question could have been a clever trick, though. He still couldn't be sure.

He couldn't tell which one was real, he was unbearably horny, and one of the mares he'd just eaten out was Chrysalis. This really wasn't going well for him, was it?

As they turned to face him, both of them blushing and grinning, he decided he needed to buckle down and figure this out. He needed a new strategy – testing their disguises with his senses wasn't working. He needed some other way to...

“So... Am I the real Cadance?” They held each other, rubbing their cheeks together. “Or am I?”

Shining Armor paused, still trying to figure it out.

“Oh, goodness. He still doesn't know.” “Maybe we should reward him for trying?” “I don't know, he's supposed to know easily.” “Ah, so we should punish him for not figuring it out fast enough...”

“Wait, wait!” He stopped them with an outstretched hoof before they could get too much farther down that line of thought. “I've got an idea. Cadance One, tell me something only the real Cadance would know.”

They glanced at each other. “Um... Which one of us was Cadance One, again?”

He pointed to the one on the left.

“Okay,” Cadance One said. “Our very first time was on your parents' bed because we didn't want to wake Twilight up.”

That was it! Only the real Cadance could possibly know something like that! Unless... He looked to Cadance A. “You, too. Tell me something only the real Cadance would know.”

Cadance A smiled. “Flurry Heart was an accident – I took the wrong pills.”

Ugh, they had taken the time to share secrets – very personal secrets – so he wouldn't be able to tell that way. This was an outrage! Cadance had no right to tell Chrysalis things like that! Maybe if they hadn't been thorough enough? “Tell me something else, both of you!”

“You once admitted you secretly wanted Twilight and me in a threesome.” “When you said 'let's try anal', you were talking about receiving it, not giving it.”

He blanched at those. Yes, they had prepared very thoroughly. How could Cadance dare tell Chrysalis secrets like that? Did she want to see the Crystal Empire's royal family blackmailed? But there was one thing she wouldn't dare tell, one last precaution they had set up between each other just after the wedding, in case one of them was ever replaced again. She had to understand how important it was ... and this was exactly the situation to use it.

He straightened, doing his best to ignore his still-raging erection. “Cadance, tell me our secret contingency password.”

“Chocolate covered candy flanks,” they said in sing-song unison.

No! How could she? Didn't she know how dangerous this was?

He racked his brain, trying to think of another question. It had to be something really obscure, something they wouldn't have thought to prepare for. It also needed to be something the real Cadance would definitely know. Where the spoons were in their kitchen cupboard, perhaps? But what if the real Cadance pretended not to know the answers either? He couldn't put it past her, not after all the effort she'd put into making the changeling's disguise perfect.

His thoughts soon drifted though. He couldn't help but look at the two Cadances. As soon as they saw his eyes on them, they grinned and turned to each other. Slowly, tenderly, they kissed. Shining Armor's thoughts vanished as he watched his wife and her copy making out, kissing more and more intently. They seemed desperate for each other's tongues, and their hooves began to wander over each other's lithe bodies.

“Hold on,” he said to them. “Hold on...”

Cadance One turned around and Cadance A grabbed her pussy, spreading Cadance One's lips open and lightly licking across the exposed pink slit, keeping eye contact with Shining Armor the whole time.

“I-I can't...” His brain completely blanked out now, leaving him with only his cock to think with. The sight of Cadance licking Cadance's pussy... And now she held her mouth open right next to it, letting her tongue hang out as Cadance One's pussy winked open and closed. It was like she was inviting him to choose one, to shove his cock into her mouth or the other Cadance's pussy, whichever he pleased. He felt a little woozy ... maybe so much blood had gone into his cock that he was going to pass out?

Cadance One looked over her shoulder at him, using one wing to caress the curve of Cadance A's back. “I think he still can't decide,” she said.

Cadance A nodded, rubbing her cheek against the other's cutie mark. “I think we need another test. Hubby, why don't you sit down on the bed over there?”

Shining Armor's heart caught in his throat. Sitting on the edge of the bed was the most common way Cadance liked to give him blowjobs. That way, she didn't get tired holding herself up like she would if he were lying down, and he could relax without falling over or anything like he might if he were rearing up on his hind legs.

But... Were they both going to...?

By the time he sat himself down in the usual spot on the edge of the bed, both Cadances were right in front of him, their eyes half-lidded as they stared at his exposed and earnestly hard cock. Cadance A licked her full lips a little, while Cadance One bit her lower lip slightly, dragging her teeth across it until it popped softly free.

Shining Armor's breath came hot just from looking at their lips, their mouths, their sultry knowing eyes.

With grace befitting a princess, each of them slowly knelt down in front of him. They glanced up at him, meeting his eyes one last time before they moved in and gave each side of his shaft a slow, loving lick.

It was instant heaven, finally getting a little stimulation after all this teasing. He could feel each of their blessedly soft tongues sliding over his sensitive flesh, and neither of them needed to hold his cock against their hooves, since they pressed him perfectly between their two mouths.

Their lips touched him and spread over the curve of his cock, and he finally felt the warm wetness of their mouths as they moved up and down again in unison. He stroked each of their candy-striped manes, guiding their hot lips up and down. “Oh Cadance, you're ... you're—”

When they came to the tip of his cock, they stole his breath away by kissing each other over his flared head. He could see a little of their tongues writhing back and forth against each other, and he could feel the tickle of it as both of them flicked across his tip.

Cadance A pushed a little forward, and before he knew it, she took the head of his cock into her mouth, sinking down on it a little. Cadance One rose upward, trailing her mouth across his belly until she reached up to his face to kiss him deeply. When she broke off from the kiss, she shoved Cadance A down on his cock with her hooves and whispered into his ear, “Does she feel good, Hubby?”

He could only groan in agreement as she shoved Cadance A's head farther down on him, gagging the other Cadance with his cock.

It didn't take long before Cadance A swatted her rival's hooves away and came up for air. She grabbed Cadance One and shoved her head down onto Shining Armor's cock even more roughly, giving the other Cadance no time to prepare. But Cadance One took it into her throat easily; his cock was already slick with Cadance A's saliva.

Cadance A gave him a sultry grin as she bobbed the other Cadance's head up and down on him. “Can you tell which one is real yet?”

Shining just blushed hotly until Cadance One came back up and gasped for breath.

Cadance A didn't need any encouragement this time. She dove back down and took his shaft into her mouth greedily, working the soft parts of her hooves over the little bit of length she couldn’t take. This time, Cadance One didn't come up to kiss him – she went down to kiss him, planting wet kisses against each of his balls in turn. He spread his legs open more to give her room, and she moved on to lovingly licking them while she fondled them in her hooves. She cherished them and treated them tenderly, as if trying to gently coax the cum out of them and into her counterpart's eager throat.

It was quickly becoming too much for him – he could feel himself beginning to flare up inside Cadance One's throat. It made her gag, and she pulled up off of him, his flaring cock head coming free with a pop and bobbing in front of her, glistening wet.

“Cadance! Cadance, I'm ready to—” Shining groaned, but without Cadance One's mouth on him, the orgasm didn't quite come.

“Ready to pick which one?” They stood up and turned around, presenting themselves for him. “Great! Mount the real me! Do it!” Each of them had long trails of glistening wetness seeping down their inner thighs, and they held their tails high, arched all the way up over their backs.

The double-vision temptation in front of him combined with his near-miss orgasm slowed his thoughts to a crawl, but he pressed through the mental fog of arousal as well as he could. Oh Goddess, he just wanted both of them so badly! Why did this have to be so hard? An evil little part of his brain supplied him an idea: if he just guessed, there was a fifty/fifty shot of getting it right. Pretty good odds, and if he did get it right, everything would be perfect. A more cautious part of him worried about the fifty percent chance of getting it horribly wrong. But then his cock chimed in, telling him that either way, at least he'd get a warm, soft pussy to cum inside.

Given how supremely horny he was, that last little argument was more than enough to sway him.

He jumped off of the bed, rushed over, and chose Cadance A at random, sliding his chest up over her rump. He could already feel the heat of her wet pussy against the tip of his cock, and he couldn't wait to take her and—

“Are you sure, Honey?” Cadance One's words froze him for a moment.

Glancing over at Cadance One, he saw the raised eyebrows, the slight hint of disapproval ... and then he knew. Cadance One must be the real Cadance! He slid off of Cadance A and hefted himself on top of his wife, grateful that she would give him a little hint like that before he did something terrible. Without hesitation, he humped his hips forward in a well-practiced motion, shoving his tip into Cadance's hot, wet pussy. Goddess, she felt wonderful! He took more and more of her, moving up on her back as his shaft slid in deeper under her tail. Her pussy clenched around him, begging for more, and he gave her all of it, hilting deep inside.

“Wrong choice, Hubby.”

Shining Armor froze, looking back at Cadance A, who stared back at him with quirked eyebrows. He looked down at Cadance One underneath him, and she glanced back at him. When she winked, her eyes flashed green for a moment.

Oh fuck! That warning had been a trick! He fucked the wrong Cadance! He fucked Chrysalis! He was still inside her right now!

He moved to pull himself out, but the real Cadance spanked him hard with her hoof, making him jerk back inward. Chrysalis moaned underneath him at the sudden thrust.

“Oh no you don't, Hubby. Your punishment is just beginning ... now do her properly – finish inside her!” She spanked him again, making him jerk back and forth inside the still-disguised Chrysalis.

It took one more smack on his ass before he got the idea and started humping away at Chrysalis again. How could his wife want him to ... how could Cadance want him to do this with— Smack! Cadance's hoof slapped down against his ass again, making him yelp again. Apparently the abuse wasn't going to stop just because he was following instructions.

Again and again she smacked him, even as he thrusted into Chrysalis with everything he had. His ass was stinging and it must have been turning cherry-red, but by then, he was starting not to care. The fake Cadance's pussy sliding over his cock was working its hot, wet magic despite not being the real thing. He was getting close again, and Chrysalis squeaked with his every jerky thrust as his flare grew inside her.

Chrysalis shuddered, pushing herself back against him as a huge orgasm thundered through her. She cried out to the ceiling and clamped down hard on Shining's cock. The lips of her pussy pulsed open again and again around the thick base of his shaft, begging for what was to come.

And it did come. Shining gripped her hard as his own orgasm broke over him. He pressed his head against her neck as his cock throbbed streams of cum deep inside the changeling copy. Some splashed out against his crotch and between her legs, and yet he still came more, pumping everything he had into Chrysalis' womb. The real Cadance's harsh spanking barely even registered in his mind as he trembled and unloaded his heavy balls into the wrong mare.

Finally, the orgasmic wave receded and the last few spurts dribbled out. He pulled out of her on weak legs and nearly fell to the messy floor when his knees buckled for a moment. Both of them panted in place for a moment, slowly recovering themselves.

Exhausted, Shining Armor collapsed back onto the bed, sitting down in the same place the two of them had given him a double blowjob. There was a little cold wetness in the spot from where their spit had dripped down, but he was beyond caring about that at the moment.

Cadance stood in front of him, grinning. Was it the real Cadance? He glanced over and saw the copy still standing where he'd left her – her head drooped down and her sides heaved as a thick stream of white cum slowly oozed out of her pink pussy. Yes, the one grinning at him was definitely his real wife.

“I really–” he had to take a moment to breathe “–fucked up this time, didn't I?”

“You did.” Her smile didn't waver.

“Can you ... do you think you can ... forgive me?”

“Oh, I'm sure I will – once you've finished your punishment.” Her grin turned a little bit evil.

So his punishment wasn't over yet... He supposed it would have been a bit too much to hope for that a few spankings were all he would get for choosing the wrong Cadance, for fucking Chrysalis right in front of his wife. What would the rest of his punishment be?

She sat down on the bed next to him and brazenly started masturbating herself with a hoof. “Chrysalis, time for Plan B.”

Chrysalis turned around and nodded. She flashed green for a moment, and then in her place stood Twilight ... a big, burly Twilight. As Shining Armor stared, mouth gaping, he saw a slender purple cock slide out underneath the fake Twilight's belly.

Cadance smiled at him as he gaped. “Looks like your mouth is already getting prepared.” She looked up at Chrysalis. “Come over and sit down on the bed next to me. Hubby, get down on your knees. Looks like you get that threesome you wanted after all.”

Shining Armor did as he was told with an apprehensive gulp. “Um, can I ask what my reward would have been if I guessed right?”

“If you'd chosen me instead of her, Twilight would be a mare.”

He glanced over at Chrysalis as she stepped over to the bed. He couldn't help but notice how that long cock swung back and forth between her – his? – legs. Looking up at Cadance, past her gyrating hoof and the squishy noises it was making, he took a deep breath. “Could I ... try again sometime?”

“Maybe next anniversary.” She patted him on the head with her free hoof as Fake Twilight sat down on the edge of the bed, that lengthy, purple cock draping over the thigh closest to him. “For now, it's time for you to get to work. And conserve your energy – it's going to be a long night.”
