Espionage by PonyWifeAsshole

Chapter 1
Chrysalis was reaching the limits of her patience with this whole affair. To some extent, she had to admire the tenacity of the Canterlot Royal Guard. In her own nation, anything less than what was displayed here was punishable with a flogging. Maybe this was her own fault, she mused, by sending that anonymous letter to the queen. Still, the threat of a direct military invasion always made security pay less attention to espionage, and this time proved to be no exception. The days of lurking in on the borders of the city had paid off, knowing exactly which guard could be cowed by a pushy, anonymous citizen of Canterlot who had "lost" her identification card. For all that sap knew, she was on her way to the royal offices for a reissued card.
The foreign queen pushed the thoughts out of her head as she looked back into her hand mirror. With her narrow chin, high cheekbones, and flowing purple and lavender locks, she was the spitting image of Princess Cadance. Ruffling the ends of her hair with her fingers gave her the appearance of a princess who was still trying to stay prim and proper, but had just a little too much to keep all the frazzle in. It was always the small touches that made the difference.
In her finished disguise, Chrysalis hurried down the hallway from the royal kitchen to Cadance's bedroom in a brisk stride, looking over either shoulder every few steps. It wasn't that she needed to stay hidden at the moment, but good acting demanded a proper narrative. It also didn't hurt for her to inspect the palace in advance, so she'd know exactly what riches she had to look forward to. Silk carpets that felt like feathers beneath her heels, classical columns and arches laced with gold, intricately carved busts, all topped with an ornate ceiling lined with crystal chandeliers every few steps. In her younger days, it would have made the queen burn with jealousy, but now she turned those emotions into motivation. If this was to be her prize, then all the more reason that it should be her personally who carried out the mission.
As she was eyeing a particularly luxurious statue studded in various jewels, Chrysalis bumped headfirst into something. Someone, given the way he sputtered an apology, a few drops of saliva landing in her ear. Fighting the urge to reprimand her roadblock on the spot, she turned to see that there was a guard stationed right in front of the princess's bedchambers. For a split second, she dug her polished nails into her palms, irritated that there was one more ripple in her plan before it became smooth sailing, but her face remained as cordial as she assumed Cadance's would be.
"Finished with your nap already, Princess?" The guard said, saluting her. His otherwise perfect uniform sported creases on the chest, where Chrysalis must have bumped into him. The visored cap atop his head did a neat job of concealing his eyes, but his reaction to the accident was enough for Chrysalis to know how to react.
"Oh, I'm so sorry." The impostor looked away, brushing the corner of her lips. She coughed. "I was just feeling a bit peckish and I didn't want anyone to know or see me." Her voice trailed off in imitation embarrassment, which the guard swallowed whole.
"I heard about that diet they've put you on to get you into that wedding dress of yours." Queen Chrysalis hadn't, but it was a safe enough assumption given the other nations she'd invaded the same way. "Lemme tell you, that's one thing I don't envy about you."
"Then you understand? You won't tell anyone will you?" Hands resting on his chest, Chrysalis looked up to him with her false violet eyes, a bit of moisture gathering at the edges. Pursing her lips together, there was no way he was going to refuse.
"Course not, Princess. Hey, I never even saw you leave you room," he said with a wink. The bit of force behind his laughter told Chrysalis that he indeed had not seen the princess leave her chambers.
"That's because the princess never left her room," she said with a wink. This was perfect, since turning a blind eye to his lack of diligence was just the invisible bribe she needed to win him over. And Chrysalis always got a kick out of telling the naked, unvarnished truth to a hapless fool.
The door creaked open with just enough of a slit for the disguised queen to slip through. The guard's hand motioned her through, staring back down the hallway he was supposed to be guarding, acting as if nothing were transpiring behind his back. Slipping into the bedroom headfirst, Chrysalis could not surpress her maniacal grin any longer. He wouldn't know a damn thing until it was far too late.
As the room sealed shut behind her, Chrysalis stopped to oberve the majesty of Cadance's bedroom. Even with all the wealth she had swindled over the years, nothing in the queen's own castle matched the opulence here. Every edge of the walls and ceiling were trimmed with rubies and sapphires. The curtains were hand woven, embroidered with silver, hanging off rods of sparkling crystal. While the windows on either side seemed ordinary enough, the glass opposite the doors was stained, a piece of artwork that filtered colored light down onto the bed that could comfortably fit five people. With her head propped up on a mountain of pillows laid the real Princess Cadance, her slim body bathed in an aqua light.
Summoning her wand in a flash of emerald green fire, the queen wasted no time casting her spell. Moments later, a shimmer of light washed over every wall, sealing all sound inside. Another flick of her wrist, and the queen dispelled her disguise. Gone was the dainty, almost bony body of Princess Cadance, replaced by wide hips and a curvy hourglass figure. The slim dress that was modest even on the princess crumbled to dust and scattered to the air. Beneath was what resembled a cocktail dress, cut deep past the neckline and up the sides, putting every bit of her voluptuous body on display. The light shades of her mostly kempt hair grew into a tangle of jade strands, woven into a mess that dared to be tamed. Pale skin turned tan, and the queen's pouty lips glossed over with black lipstick.
Seating herself on the bed, the queen leaned over her victim, hand on either side of her body, to get a good look. Cadance's modest chest rose and fell softly with her breaths, not a trace of snore in her royal windpipe. Still the way Cadance had yet to even stir, either she was a hell of a heavy sleeper, the recent preparations for the marriage had tuckered her out, or this was the finest mattress in all of Equestria. The exact reason wasn't important, though she made note to test that third hypothesis later tonight. Ready to move onto the next phase of her plan, Chrysalis clamped her hand down onto Cadance's mouth, which did a good job of waking her instantly. Of course it wasn't necessary, given that she had silenced the room moments ago, but it was the small touches that made the difference.
"No, you don't know who I am," Chrysalis said, knowing exactly what Cadance would yell if given the chance. "And don't bother reaching for your wand." Pointing her own magical implement towards Cadance's nightstand, a quick shot of green energy knocked Cadance's wand away, well out of reach.
Setting hers down, Chrysalis used her now free hand to pin Cadance's wrist down against the bed, straddling the smaller woman's torso with her muscular thighs. With the difference in size between the two and Chrysalis' superior position, restraining the princess would have been less than a struggle. She wanted to watch her victim thrash and fail, however, as she loved watching people slowly submit to her will. As Cadance uselessly kicked her legs, Chrysalis noticed how the pink haired girl was too delicate to even consider biting the hand clamped over her mouth. This might be even easier than originally planned, the queen thought.
"I've got a schedule to keep, so I'll make this brief." It wasn't like her to reveal plans, but given the circumstances, it was going to be so much better this way. "I'm going to be taking your place for a good long while. I've done my research, but there's still one thing I don't know about you, and that's how you act when that stud of a fiance you've got fucks you." The muffled sounds beneath Chrysalis' hand rose and Cadance's eyes widened. Releasing the gag, the queen only allowed the princess a few syllables before an open palm across Cadance's face silenced her. "I already know how you talk." The dark queen brushed aside the dark fabric between her spread legs, revealing a pair of plain, black panties, shuffled just past her thighs, and a large, veiny penis jutting over it. "I just need to know how you moan."
The collar of bride-to-be's flimsy dress stood no chance against the assaulter's powerful grip. In one tug, it tore in half, leaving Cadance's small breasts defenseless in the open air. Chrysalis easily palmed them in each hand, carressing gently in her best imitation of foreplay. As blood rushed through Cadance's body, Queen Chrysalis marveled at the nipples becoming erect beneath her. Forming perfect peaks atop her pert breasts, the nubs were massive in comparison to the rest of her bust. That was one detail that Chrysalis would have missed otherwise.
"Get into character, it's more fun that way," she said as she bent down, pinning Cadance beneath her. Her heavy breasts spilled on top of Cadance's own, the fabric of the queen's dress the only barrier between them. Gripping the younger girl's throat in her hand. the queen forced her lips onto her victim's, prying the tight lips open with her snaking tongue. Warmth and wetness met her mouth as she rocked her body, grinding her hips against the princess's struggling body. All the while, the princess clawed and kicked and screamed into her rapist's mouth, but was unable to dissuade her.
"Get off me, you freak!" the princess screamed at the top of her lungs. Her fingers continued to scratch at her assailant, but all that accomplished was tearing away bits of the queen's clothing. While it was leaving red marks up and down her body, the pain only spurred the green haired woman on. Watching Cadance fight back was only going to make breaking her down all the more satisfying. Still, the impostor couldn't risk the girl getting lucky and somehow making a break for the door. Picking her wand back up and waving it twice, a green tendril slithered around Cadance's wrists and pulled them together, tying them behind her back. "Guards! Guards, Help!"
"Please, you didn't think I'd soundproof the room first?" Chrysalis mocked her in a singsong voice. Crawling down Cadance's body without lifting the weight of her own off, the invader stopped with her eyes on the violet haired girl's perky mounds. Her head dipped down, taking one into her mouth. Teeth clamping down on the large, erect nipple, she pulled and tugged. Cadance arched her back, trying not to let her unknown attacker tear her flesh off, the pain eliciting screams of protest. When the pulling stopped, the queen took more of the supple breast into her mouth, sloppily sucking while her hand made similar motions on the other. Cadance continued to kick and yell, but far less vigorously. Whether it was from the lack of pain, the addition of pleasure, or the breaking of her will was anyone's guess.
The princess's tits were soft and pliant in Chrysalis' mouth. Every flick of her long tongue sent a muffled groan through the air, barely muffled by Cadance biting her own lip. When she nibbled and chewed with her teeth, Cadance would push back, but more as a reflex than in any real effort to throw the queen off. Looking down at her work, Cadance's tits glistened with a coat of the queen's saliva, pink tips standing proudly in the air in spite of the princess's desires, all framed by the torn open nightgown.
"Your Shining Armor is a lucky boy," she teased as she continued to tear the sleeping garmet in two, exposing her flat stomach with its outie bellybutton - another important detail Chrysalis couldn't afford to miss. The nightie ended halfway to Cadance's knees, and soon she was wearing something that more resembled an ineffective bathrobe. Her slender thighs and narrow hips were protected by a pair of simple white panties, already stained by a spot of moisture. "It's cute how you resist, yet you don't," the queen said. One of her hands palmed Cadance's crotch, rubbing the underwear against her slit. The princess snapped her legs shut in reflex, but that only served to trap the intruding hand there.
"Stop you monster," Cadance managed to get out between gasps. The way her hips gyrated to throw Chrysalis off only served to grind her genitals against the queen harder. The way sweat was beginning to bead on the princess's forehead and her breathing became more ragged, the queen wagered that the girl was starting to like this. The green haired woman curled her fingers, pressing a bit of fabric past her victim's pussylips. Lavender hair flew through the air as Cadance grunted in a contradictory mix of disapproval and pleasure. Her eyes squinted shut, Cadance laid her head on the pillows and panted, unable to form words. Another tease of fingers barely penetrating her hole and Cadance gasped again, this time kicking her legs wide as a prolonged moan escaped her lips. The queen made a mental note that the princess was very sensitive.
As expected of royalty, Cadance showed no signs of a single hair between her legs. Her labia were well groomed, not a trace of messiness on them save for the juices that shone beneath the colored light. Dipping two fingers into Cadance's tunnel, Chrysalis spread apart the lips to get a good look inside. Almost as pink as her hair and glowing with moisture, it was adorned by a clitoris only just big enough to peek from under its hood. While this was technically enough information for the impostor to work with, she had a lot of steam to blow off today. And really, who would pass up a chance to fuck royalty?
The queen dug her nails into the princess's lean thighs, making sure that her legs stayed spread. Bowing her head, the older woman basked in the scent of Cadance's unwilling arousal before laying her tongue against the girl's entrance. The muscles in Cadance's legs quivered beneath Chrysalis' touch. The queen made a single lick, agonizingly slow, up the path of her slit, shivers of disgust coming from Cadance's vocal chords the whole time. Repeating the oral tease, Chrysalis let the musky flavor roll in her mouth as she flicked the small clit with the tip of her tongue. That one sent the girl kicking again, this time with her hips bucking into the queen's face. Chrysalis was only too happy to oblige her unspoken wishes.
Plunging her tongue deep into the princess's depths, Chrysalis hummed gently against her clit. She nearly expected a pair of hands to start pulling on her hair before remembering that Cadance was a bit too tied up for that. Digging her nails in to keep the sensations flowing, the queen kept her tongue rolling around, teasing up and down her victim's inner walls. Every few traces of the princess's pussy, the green haired woman would withdraw her tongue, nibble a few times to both sides of the wet slit, and lap at the engorged clit. Cadance was not even forming words anymore, resigned to struggling for breath and squealing when exactly the right spots were hit. A few more experimental licks, tongue darting in and out, flicking up and down to explore her caverns, and Chrysalis found exactly where Cadance was most sensitive. She gave her clit one last suckle and nibble before withdrawing, Cadance whining in cliffhanging pleasure when the feeling of the queen's breath left her vagina.
Chrysalis eased her hands off Cadance's thighs, making sure the legs would not snap shut. They complied. Chrysalis moved her head a few inches lower, arriving at a puckered rear entrance. It was a clean pink and bore no smell at all, as if the princess never even used it. Well, that would be fixed soon enough, even if it was going to be in the wrong direction. Pushing the tip of her tongue against the sphincter, all Chrysalis could hear were a few confused words, barely hinged together between Cadance's fight to keep air in her lungs. She forced herself in, the mixture of saliva and pussy juice lubricating the dry hole. This time, her ministrations were met with a positive shriek and legs kicking into the air.
Cupping her ass with one hand, the invading queen slipped two fingers back into her proper hole, flooding Cadance will all kinds of forbidden sensations. Mixing taboo pleasure with the typical kind was sure to throw Cadance's head into confusion, and the irregularity of her breathing told Chrysalis that it was working. Fingers twitching and dancing inside her pussy, tickling at the sensitive spot at the top of her pussy, while her palm massaged circles around her clit, it seemed to distract Cadence from the violation of her anus.
She couldn't hold in her chuckles as her tongue pushed deeper into the princess's rear, nose buried in one of the girl's soft buttocks. Every time she licked deeper, Cadance would moan something that sounded like "No," only to be drowned out by more screams from the stimulation in her pussy. The muscles in Cadance's legs were trembling, telling the queen to please harder and make the girl bend to her will. Planting her lips against the ring of the princess's asshole and ramming a third finger into her slit, Chrysalis gave it all that she had. Her efforts were rewarded almost immediately.
Cadance's legs snapped together, scissoring around Chrysalis' head and draping the girl's feet over the older woman's back. Her hips thrust wildly upwards. The force would have thrown the queen off, were she not pinned down. Laughing in delight as every fiber of Cadance's body vibrated and shuddered around her, the green haired woman felt both orifices repeatedly squeezing and relaxing around her digits. With Cadance's body humping the air, Chrysalis did not stop, continuing to lick in and out of her ass and pump fingers into her pussy, prolonging the orgasm as long as she could. A small splurt of juices squirted past the queen's hand and into her hair, another cute detail the Chrysalis would remember to copy. All the while, Cadance yelled all kinds of filthy curses, begging for more pleasure in her dirty holes like she was a common whore. Seeing and hearing proper royalty turn so filthy sent thrills through the queen's entire body, and made her cock throb with desire.
"You have what you want," Cadance panted, her words shaky from the climax she just experienced. The way she sniffled between words, she had to be on the verge of tears. "Leave me alone and I promise I won't tell anyone."
"How adorably selfish of you." Chrysalis' answer came as she pinched the princess's cheeks together, causing her thin lips to pucker. "I gave you your pleasure. Shouldn't royalty be courteous to return the favor?" Cadance's violet eyes darted downwards, looking over the landscape of her own body and staring at the hideous, drooling beast between her captor's legs. The tip hovered inches away from her entrance, and Cadance knew how futile trying to close her legs would be. She squinted her eyes shut to try to tune it all out.
"Please don't," were the only two words Cadance could say.
"Too bad," were the two words Chrysalis said back.
With one hand on her penis and the other spreading open the girl's entrance, the queen eased in the tip of her length. Cadance gasped immediately, twitching again. As much as all this foreplay made her wantr to ram herself in to the hilt all at once, she could tell that would be quite the task with Cadance's tightness. As bit by bit sank into the princess's velvety folds, Chrysalis sighed in pleasure and relief. The tight pussy was like a wet, warm heaven as it gripped and carressed her, each "Yes!" of pleasure from the impostor's mouth matched by a "No!" of pain by the real princess.
And then Queen Chrysalis hit a road block.
"Are you that old fashioned?" The queen punctuated her question with a chuckle. What a lifesaver this was. If she had omitted this detail and Shining Armor found out, her cover would have been broken in a snap.
"I was waiting for the honeymoon," Cadance sobbed. There was no more pleaing, just resignation and despair. If Cadance's spirit had not yet been broken, she was well on her way there.
"It won't hurt too much. The hymen breaking, that is," she added after a pause. "Knowing that I'm the one who's riding him every night, well that must hurt." Watching Cadance blink back tears in confusion, Chrysalis seized her chance. Clutching her captive's hips, she thrust herself down to the base, breaking past the thin membrane and burying herself whole inside of the princess. A coo of enjoyment escaped her lips. As if violating such a tight pussy weren't good enough, she was robbing the princess's first time. The empowerment of prying away the girl's virginity only made the warm sensations in her member all the better.
Cadance's will found one last wind to fight back as she was fully impaled on the queen's cockmeat. Without the use of her arms, she sat up in a flash, her skull barreling towards the other woman's. Before she knew what was happening, Chrysalis felt bone against bone, catching the headbutt full on. Sputtering and cursing for a moment, she could see Cadance already trying to crawl away. Too bad the bed was so large and the mattress so soft. Escaping was not even possible. Chrysalis descended on her escaping prisoner, pinning the girl down with a single hand on the back.
"So you want to play rough, do you?" The princess's only response was uselessly kicking her legs and wiggling her torso some more. "Fine, we can play rough." Chrysalis laid down on top of Cadance, her large breasts pressed into the girl's shoulders. Her erection pressed against Cadance's ass, which made the princess struggle even more. "Don't worry, we're going there. But I like to save the best for last." Grabbing a fistful of pink hair in each hand Chrysalis tossed Cadance back to the center of the bed, face up.
"As much as I'd love to degrade you doggy style," Chrysalis said, "it's much better if you have to look me in the eyes the whole time, don't you think?" The queen forced Cadance into a kiss again, but this time without any pretense of gentleness. Grabbing her hair and pulling until she was forced to scream, Chrysalis bit on Cadance's tongue and lip until the screams went from protest to pain. When the younger woman yanked her head away, Chrysalis sank her teeth into the princess's exposed neck. With teeth pinching at her tender muscles and hands groping her breasts, Cadance whimpered at the rough ministrations. It was only a matter of time until the molestation ceased and that battering ram of a cock was at the gates of Cadance's entrance again.
If the princess was going to be punished, then Chrysalis was going to make sure she remembered the pain. She channeled magic through her hands into her already sizeable length, the shaft growing with each pump. Every time it grew larger, Cadance's eyes widened, shocked and praying that each growth would be the last one. When the queen finished, she had added a number of inches to the length and made it into a positive monster in girth.
"Since you'll never get to experience your beloved, I'll make this one extra memorable," Chrysalis said. She tried to push her colossal prick into Cadance's tight cunt, but the tip refused and slipped by, rubbing the cock against Cadance's moist lips and swollen clit.
"No, it'll never fit." Even as tiny moans peppered Cadance's words, the pleasurable stimulation was obviously outweighed by fear, judging by her trembling voice.
"It's called rape, dear. I'll make it fit."
Several times the fat, swollen head of Chrysalis' cock tried to pierce Cadance but slipped out, resulting in another messy smear of juices on the princess's pussy. Each time Cadance would whimper and Chrysalis would hum, both in anticipation. When the prick finally forced its way through, a pair of cries filled the room, one in pain and the other in ecstacy. Not stopping to enjoy the feeling just yet, the queen grabbed her prisoner by the hips once more and slammed herself in, gyrating her hips upwards. The royal vagina was like a vice around her, squeezing and milking her for all she was worth.
Cadance's eyes were wide in shock as tears streamed down her cheeks. It must have been outright painful for a virgin to receive such an enormous penis on her first time, especially so violently. The queen began to hump away, pulling her cock out to the tip before thrusting it back in with long, agonizing strokes. A lewd squelching sound accompanied each hump, fluids being pumped out of the tight cunt as it was repeatedly filled and emptied. Every time their hips met, the sound of flesh slapping against flesh was echoed with a moan of joy. Every inch of Chrysalis was being clenched and massaged by Cadance's velvety walls, and every stroke brought her closer to orgasm.
The younger woman's body tightened up at first. Every muscle in her body wound up, tense with pain and shock. As the pounding continued to stretch her pussy beyond its limit, something inside of her broke. Cadance went limp. Her head rolled to the side, eyes idly staring off into nothing as the pain consumed her. Seeing the princess collapse, Chrysalis knew something was wrong - or right, from her point of view. Forcing the girl to look her in the eyes, Chrysalis saw that Cadance's gaze was vacant and empty as a doll's. The only signal that she was still conscious were the small gasps and moans every time Chrysalis' large meat filled her.
The queen locked lips with the princess again. To her surprise, Cadance responded, kissing back and tangling tongues. As Chrysalis sloppily lavished the lavender haired girl with her tongue, she ceased her full length strokes and began pushing her hips against Cadance's, prodding her wet cunt deeper. Once more surprising the queen, Cadance lower body responded in kind, grinding back as if she wanted the thing to ram into her cervix. But no, the princess still had a glaze of absence in her eyes. She was little more than an animal now, only responding to carnal stimuli. With the realiation that she had finally won, Chrysalis decided it was time to formally declare victory.
She wrapped her arms around Cadance in an ironic embrace, pressing her curvy, womanly body against the princess's far thinner form. No longer concerned with how her victim was feeling, if indeed she was feeling at all anymore, the queen fucked the tight tunnel in a frenzy. Their bodies fully entwined and Chrysalis panting the whole way, the short, powerful thrusts squeezed every inch of her pole. The vagina was tighter than anything she'd experienced before, and every movement sent waves of pleasure up her length and into the core of her body. Her moans grew increasingly high pitched as her peak approached, and in a display of self-control, she stopped for a moment to pull out.
After being so generous to get her victim off even once, Chrysalis was not going to let Cadance skip out on returning the favor. Crawling up the tied down girl's lithe body. Chrysalis straddled Cadance's chest, her long meat dripping with the princess's natural lubricant. The empty look in her eyes was still there. The sight of such a prim face soiled with saliva and bite marks was a delight. Taking her hard meat in one hand, she swung it, smacking Cadance across the cheek, hard enough to leave a red mark. The princess's head rolled aside before a loud gasp evacuated from her lungs. Chrysalis wasted no time, making sure her captive's first sight back in reality would be a memorable one.
Grabbing her cock in both hands and stroking like the lust-filled beast that she was, blisteringly hot pleasure soon flooded her entire body, rushing down to her loins, and erupting out of her meaty pole. The first spurt of semen shot straight into the princess's wide open eyes, a shot that made Cadance wince and groan. The next splattered onto one cheek, glazing half her face in a single glob. Chrysalis continued to stroke as more ropes of cum flooded out. Cadance's face was covered in no time, and as Chrysalis' aim faltered over the course of her long orgasm, much of it landed in Cadance's hair and a bit even flew up onto Chrysalis' own body. Chrysalis moaned in pleasure the entire time, screaming obscenities and not a single mention of Cadance's name, uncaring of the body she just used for her pleasure. When the pleasure calmed down to a warm buzz, she looked down. A thick strand of cum still hung off the tip of her still throbbing, still erect penis, connecting her to Cadance's messy visage. Chrysalis had to congratulate herself; it normally took at least five men to produce enough sperm to turn a girl into a glazed donut, but she'd done it all by herself.
"Normally, it would be over by now," Chrysalis said as her fingers rubbed her cum into the princess's hair. Making a sticky mess out of her nice hair proved to be fun. Suddenly, the queen grabbed Cadance by the hair and pulled her up, so their faces were a breath away from each other. "But that little show of being uppity is going to cost you now." Throwing Cadance back onto the bed and reaching for her wand, Chrysalis cast another spell on herself. A sickly green light enveloped her body. Her form began to warp, every part of her body fluctuating in size. Cadance could only stare in shock as she watched the changling magic before her eyes.
After a few moments it was done. Cadance gasped. On top of her was a reflection. Chrysalis had used magic to transform herself into the very image of Cadance, down to every last detail. Chrysalis' dress was not at all suited to Cadance's much smaller body, the fabric hanging off her every joint. There was also the penis standing proud between her legs.
"Don't worry, I can get rid of it at will, so your little fiance won't suspect a thing." Even her voice mimicked Cadance's perfectly. The disguised queen wrapped a hand around her member, idly stroking it. It was much smaller now, still quite long but much less girthy. "I think this size fits your frame much better, don't you?" Cadance had no answer. "Of course, this will suit the next act better anyway." The false Cadance picked up the real one in her arm, strength still intact, and threw the real princess over her dresser, bent over and face to face with a mirror.
"What a shame, there's hardly anything here to grab," Chrysalis said as she delivered a hard spank across both of Cadance's buttocks. In the mirror, she could see the princess biting her lip and wincing in pain. "I might have to make some slight adjustments, for Shining Armor's sake. Who doesn't like a plump bottom to grab?" She pinched Cadance's tight, lean bottom, which made the princess wriggle her hips in response. "And you expect to give birth to an heir with these bony things?" she mocked as she grabbed them in her hands. "With a stick figure like this, Shining Armor must be marrying you for your title and nothing else."
"Leave him out of this," was all that Cadance could whimper back. She was still a mess, the thick volume of cum decorating her face dripping and pooling onto the furniture.
"I'm about to steal away all of Equestria. What's stealing a little bit of sex on the side?" Spreading apart Cadance's asscheeks, the impostor revealed the real woman's pink pucker, still moist from the rimming. Still slick with juices, Chrysalis pushed her cockhead against the forbidden entrance, only to be met with resistance.
"Please, just don't," Cadance begged as she sniffled.
"I haven't listened to you until now. What makes you think I'm about to change?" The cruel grin that spread across the fake Cadance's face looked like somebody completely alien to the real one. "It's only going to hurt more if you clench, you know."
Not that the real Cadance listened. Her anus remained tight, denying the invader entrance. Undeterred, Chrysalis continued to attempt to thrust in, always slipping and sliding her cock in the valley between her cheeks. Every failed penetration made Cadance thrash from one side to the other, knocking all her cosmetics and books everywhere. Still, the queen never lost her grip.
After countless tries, the impostor got lucky once and forced her way in. It was only the head, stopped from going any deeper by the tightened sphincter, but it was an even more sensuous fit than her pussy. It was a good thing Chrysalis had shrunk herself, as the size she used in Cadance's pussy would have never made it through. As soon as her anal entrance had been violated, Cadance screamed bloody murder. Chrysalis clamped her hands over her ears, her cock nearly slipping out without any guidance. When the princess finally ran out of breath, the maniacal grin came back to the queen's face.
"Scream all you want. Nobody's coming to save you, least of all your prince." She cackled as she dove deeper, forcing her way into the unwilling orifice. As lubricated as both Cadance's asshole and Chrysalis' cock were, it was a struggle to get every bit of length inside. The princess never stopped squirming and the queen found it harder to keep her under control with this smaller body. When her own crotch met its twin, she paused for a moment bask in the empowerment of the act.
"You should be so lucky. I bet Shining Armor would be too shy to ask you for anal." Chrysalis withdrew a little, eliciting another gasp from Cadance as the queen's cock was milked by the tight hole. She slapped the flat butt that she was violating. "But with an ass like this, would he even want to?"
Apparently, the mocking was too much. Cadance broke down crying, tears mixing with the sticky fluid coating her face. Her mumbles were indistinct, the queen only able to make out a stray "No" or two. The queen had no idea if it was all the physical pain or if there was an underlying insecurity about her body, but she was going to play the cards anyway. It was the small touches that made the difference.
"You don't even have tits that can jiggle when I can do this." Chrysalis rammed herself into Cadance again. In the mirror, Chrysalis' small breasts did have a bit of bounce, but nothing like what her natural body would have. "Don't you know how much men like to rub their dicks in cleavage? You wouldn't have that with every push-up bra in the world." Pulling Cadance's hair so her head was raised to look in the mirror, Chrysalis used her other hand to tear open her dress, revealing her small, copied mounds. "Look at how small they are!"
"He likes them the way they are," Cadance said while trying to choke down sobs of pain.
"Bullshit, he's just telling you that to get into your pants and become royalty." Chrysalis hammered into Cadance's ass, the tightness around her cock a secondary pleasure to tormenting her captive. With how tight this anus was, Chrysalis could only imagine how good it would feel if she were sporting a larger penis. Though she had just orgasmed, she could feel the intense pleasure of the princess's rear end unwillingly milking her for a second load.  She pulled up Cadance's head again, forcing her to stare at her doppleganger fucking her from behind.
"Which one do you think he's like better?" Chrysalis asked, the twinkle of madness still in her eye. "The poor, dejected slut covered in cum, or the strong woman who knows what she wants?" Though they had the same body and face, they looked worlds apart. The real Cadance was beaten, tired, and covered in cum and tears. The fake one wore a cruel grin, and everything in her body language exuded power. As Cadance's asshole loosened to accomodate for the phallic intruder, Chrysalis pounded harder, causing the dresser and mirror to shake.
"It's almost too bad that Shining Armor is going to miss you, because you are one good fuck," Chrysalis said as she could feel the pressure building in her cock a second time. She picked up her pace, ploughing Cadance's anus until the princess was screaming with every inch that entered and exited. "But fuck it, I'm better." Her last few words were ragged with gasps, unable to contain her pleasure any more. She pulled out of Cadance's ass with a wet pop, and one stroke of her fingers was all it took for her to cum a second time.
The first wave was voluminous as ever, landing on the small humps that Cadance called a butt. Continuing the stroking as she moaned in ecstacy, thick white semen continued to shoot and splash all over Cadance's posterior and back. Each load was just as heavy as the last, covering the princess's behind just like her face had been. When her climax had calmed down, Chrysalis looked down at her work, seeing a glazed pair of asscheeks, still red from pounding and spanking. Cadance was limp on the dresser,  collapsed now that it was all over. The queen swiped two fingers across the landscape of cum, quickly dipping them into Cadance's violated anus before forcing her fingers into the princess's mouth.
"Frosted buns. Aren't they tasty?" Cadance licked the fingers by reflex only to cough and choke from the flavor. Chrysalis laughed once more before throwing her victim to the floor. Nightgown torn open and soaked in semen, the real Cadance was a vertiable mess. It would have been sad if anyone who cared could see it.
"Any last words?" Chrysalis was waving her wand as more of her sickly green magic swallowed up Cadance.
"Please, just let me live," Cadance begged.
"Oh don't worry dear, I'm a spy at heart, not a murderer. You're just going where nobody will ever see you again." She smiled at her real twin, delighting in the confusion that Cadance had at being tormented by her mirror image. "Well, I'll be seeing you on a regular basis, if you can promise to stay as tight as you did today," she added after a thought. "Be good, and maybe I'll bring along your little boyfriend."
Cadance screamed as the magic swirled around her, teleporting her away. Even if the room weren't soundproofed, nobody would have been able to hear her over the victorious laughing of Queen Chrysalis.
