Princess Cadance has the best idea, a present to her Shiny that will make their wedding the most exciting thing ever!

Before arrangements were finalized, both Shining Armor and Princess Celestia had offered to make it a theme wedding—something spicy. Cadance hadn't liked any of the ideas they had come up with, so she arranged her own special, exciting wedding: an invasion theme!

Contains: Lots of sex (more sex than your body has room for), cunnilingus, rimming, ovipositor (yay, changebugs!), and a lot of "the ol' in and out." Shining x Chrysalis, Shining x Chrysalis x Twilight, Cadance x Twilight, Cadance x Chrysalis, Shining x Celestia... Basically, clopfic.

You put the penis in. You take the penis out. You put the penis in, and you DON'T shake it all about.

"Shiny," Cadance began, looking at her fiance with undisguised enthusiasm. "Remember when you and Princess Celestia talked about having a theme for the wedding?" She levitated the special headdress from Saddle Arabia and held it beside her face—admiring it in the mirror. "I changed my mind."

Four words shifted Shining's attention away from his future wife's plot so that he looked up at Cadance's face. "What, we can have a mariachi band?" He wore as innocent a smile as he could; he knew exactly what Cadance was talking about.

"Just keep your mind open, Darling. I have something special planned." Turning, Cadance flung the bridle at Shining, her magic animating it and securing her "stud" in the mare's attire. "Now come here and show me that thing you do with your hips."

"So no mariachi band?" Shining stood up. Wearing a pair of the finest silk stockings, a gauzy dress, and now a Saddle Arabian mare's bridle, he advanced on his love.

Cadance shook her rump from side to side in offering to her lover. "Oh, I think we could fit them in somewhere…" She didn't squeal when Shining mounted her, she moaned.

Twilight was not dealing well with the wedding. Everywhere she looked, Cadance was acting strange. It wasn't just little things, either. Twilight Sparkle remembered Cadance from when she was a foalsitter, and this Cadance just didn't sit well.

Her friends had blown it off as "nerves before the big day," but Twilight didn't buy it. Something very strange was happening, and Twilight Sparkle would get to the bottom of it.

Stomping her way to the townhouse her brother (in his role as captain of the Royal Guard) lived in, Twilight banged on the front door loudly. She waited for a few minutes with no answer, then tried again.

Finally, the light came on in the front room, and Twilight could hear her brother's hoofsteps approaching.

Shining Armor was a little unfocused when he opened the door, but the sight of his little sister made him perk right up. "Twily!" He made room for Twilight, and his sister stalked into the room as if it were enemy territory. "What's the matter?"

Twilight's emotions rushed to the fore, and she looked up at her brother. "We need to talk. I think you're making a—"

"Ahem!" Chrysalis was still in character, more so than usual. Her disguise was perfect, she had matched Cadance to a T.

His attention snapped towards the beautiful monster. Shining gazed upon "Cadance," but he knew too well what was beneath. His pulse quickened, and Shining gulped. "Y-Yes, dear?"

"In the other room, now." Chrysalis looked between Shining Armor and Twilight Sparkle, but her eyes lanced back into Shining's, and she gave a little pulse of her magic. She had the absolute satisfaction of seeing his legs wobble a little. Turning, she made sure to swish Cadance's tail from side to side just enough to tease, but not show what was beneath.

"I better—" Shining's voice failed him a moment. He gulped, cleared his throat, but nothing to stop his mind from focusing on the reminders of Chrysalis' control. "I better go see what she wants!"

Twilight stared at her brother as he chased after his bride-to-be like a lost puppy. Once Shining was in the next room, a pink hoof swung the door closed—but it didn't close completely.

The moment they were alone, Chrysalis flared her power again, and watched it glitter in Shining's eyes. "I told you, when I am in command you do not talk to anypony!" She lifted one hoof to her chin and looked over Shining. "You love your little sister a lot, don't you?"

Shining whimpered, and nodded. His mind raced, struggling against the hold Chrysalis held on him. When he struggled and fought against the power in his mind, he let out a little moan.

"Your punishment, then, is to please your mistress." As Chrysalis turned and lifted her tail to Shining Armor, green fire enveloped her.

The flash of green light caught Twilight's attention. Something in the kitchen seemed to burn really hot and really strange for just an instant. Walking quietly up to the door, she pressed one eye to the crack.

Staring at the form of his little sister, Shining trembled. "M-Mistress. I'm sorry…"

Chrysalis wasn't sure about such a small form, but punishment was punishment, and Princess Cadance had told her to do whatever she wanted within the rules. "Big brother, I'm so hot and horny." She affected Twilight's voice perfectly, flashing her vulva at Shining. "Lick me, pet."

The magic in Shining Armor's head was barely a touch, and he knew it. But in the context of the games Chrysalis was playing with him it was warping his mind and forcing him to be her plaything. He nodded and leaned forward.

Twilight Sparkle stared at the scene before her. Her big brother was nuzzling and licking under her own clone's tail. She watched as, with softly glowing, green eyes, Shining started servicing clone-Twilight's vulva.

Chrysalis wasn't blinded by the pleasure—Shining Armor wasn't that good at cunnilingus—she spotted Twilight Sparkle at the doorway, and fought every instinct that wanted to call the scene off. She waited, trying to judge if Twilight was "in on it" as Shining was.

"You taste so sweet—" Shining's words cut off as he returned to his diligent lapping. The buzzing in his mind reminded him of the game, but he really couldn't deny how hard he was getting from the dominance game Chrysalis was playing.

While Twilight stared at her brother, she shivered a little. The clone-Twilight turned a little, and suddenly Twilight Sparkle had a perfect view of her brother licking and lapping at, well, her.

Twilight's rump—the real one—hit the floor with barely any sound, and she couldn't stop one of her forehooves from migrating back. Rocking her hips to the side just enough, Twilight Sparkle began masturbating to the sight of her brother eating her out.

The mirror before Chrysalis gave her a perfect view of Twilight—again, the real one—and the changeling queen's eyes widened as she watched Shining Armor's little sister start to rub herself. She's totally into this, Chrysalis thought. She opened her mouth and let loose a happy moan.

A new game started. Chrysalis knew that she couldn't get too vocal without really ruining things, but she could definitely make some sounds for their guest. "Sh-Shining Armor, eat my pussy like you love it."

Twilight's hoof sped up, and she started to tremble a little. Biting her lower lip, Twilight Sparkle couldn't peel her eyes away from her brother's feast.

Shining did his best—his very best—to please his mistress. He teased around her outer lips, nuzzled and gently nibbled the tender flesh, and even curled his tongue around her clitoris when it presented itself, but nothing was working. Chrysalis was moaning, and expressing her delight for him, but he needed to go a step further.

Both Twilight and Chrysalis' eyes widened (in exactly the same way, since they looked exactly the same) when Shining lifted his snout and pressed his tongue to Chrysalis' anus.

"Good pet, your previous owner must have trained you well." Chrysalis arched her spine and moaned loudly as Shining's tongue dug into her tailhole. She snapped her teeth together and snarled in delight as he did an expert job of eating her plot.

Twilight Sparkle had never even thought of anal sex, let alone anal to oral sex. Her books had been most explicit when it came to putting penes in vaginas, but this was something really odd. And really good.

The sight of the mare hoofing herself towards climax was almost as good as Shining's efforts. Chrysalis tried not to stare at the other purple unicorn, but her eyes were drawn to Twilight. Studying each stroke of Twilight's hoof, Chrysalis wanted to abandon Shining and march over, demanding the right to clean the glistening feminine fluids from Twilight's naughty hoof.

Shining Armor's tongue seemed to become more active, and wrapped in her own fantasies as Chrysalis was, she couldn't stop her body—or in this case Twilight Sparkle's, but not actually Twilight Sparkle's—from peaking. "Fucking lick my asshole you dirty little stallion!"

Happiness filled Shining. He kept working his tongue around in his mistress, having to fight her strong muscles for the pleasure of getting her off. A tight grip around his rock-hard shaft caused his eyes to narrow, and he let out a groan.

Twilight Sparkle, her horn glowing, had no idea what she was doing. She had never been with a stallion before, so her experience driving a stick was non-existent, but it didn't stop her from stroking her brother's shaft.

"Keep licking, pet. Your mistress wants another orgasm." Chrysalis' demands were literally just a distraction. She couldn't believe Twilight was stroking her brother off with her magic, but it made the moment better, if anything. "More! More! More!"

Shining was trapped by his mistress. Chrysalis' words were clear, however, and despite what he thought was her magic stroking him off, he kept on eating her ass. The musk under "Twilight's" tail was intense to his nose, and with his snout pressed up firmly where dock met ass, he was subject to all of it.

Her hoof was still as she worked. Twilight stroked her brother off, forming her magic into a soft, rubber-like tube. Through her magic, Twilight could feel the hardness and heat of Shining's penis. She gave a little groan, and before it could grow too loud she jamed her hoof between her lips to silence herself.

The taste of musk hit Twilight's tongue; in her haste to silence herself, she had pushed the hoof she had used to masturbate with into her mouth. Her aborted moan grew, and she knew she had to leave her hoof there. She focused all her attention on Shining, and tried to imagine what it would be like if it were actually her there, and not her magic.

Chrysalis lost it when she saw Twilight taste her own musk. The sexiness of it, the lewdness of a sibling rubbing one out and then rubbing out their brother was overwhelming, and Chrysalis wobbled on her hooves as another orgasm rushed through her.

"Pet…" Chrysalis tried to put some semblance of dominance into her words, and failed. Steeling herself against Shining's lapping of her sensitive anus, Chrysalis raised her voice in command. "Shining Armor, climax now!"

The command was a magical trigger, or so their little game went. Shining groaned and trembled, shoving himself forward in quick, bucking thrusts. It only took five humps before his body tensed up and he started making a mess of the floor.

Twilight was the pony in control of the firehose, or so it seemed, and tried to work out what to do. She know what she wanted to do—she wanted to march into the room and crawl under her brother, guzzle every drop of him down—but she could never fulfill that fantasy. Instead, she tugged at Shining's shaft, and aimed it up and on a slight angle.

Shining Armor stared, as somehow his shaft was painting the purple plot before him. White, thick seed stained "Twilight's" fur, and it made him pump and spray all the harder.

The act was over, and Twilight Sparkle knew she couldn't still be in the doorway when either her brother or the clone-Twilight turned around. Putting all four hooves on the floor, Twilight used her magic and was gone with a soft POMF sound.

Twilight was terrified of what she had felt. She locked herself in her room until she was sure the rehearsal of the wedding ceremony was over. She had to confront her brother and tell him what she had done, but at the same time she couldn't.

Her friends were so far away from being good targets for this kind of unburdening that she dismissed them out of hoof. Princess Celestia… "Sure. I will totally walk up and say, 'Your Highness, I masturbated while jerking off my brother, while a monster controlled his mind!'"

She let out a blast with her nose that sounded very horse-like. She had to tell somepony. Getting to her hooves, Twilight Sparkle made her way to the door of her room, only for it to swing open.

"There you are. You weren't at the rehearsal." Chrysalis, wearing Princess Mi Amore Cadanza's form again, stepped forward and looked at Twilight. She liked what she saw, and her memory of what the two of them had done with Shining the previous night almost made her shiver in delight. "Shining Armor was quite distressed."

"You!" Twilight broke from the mental lock-up she had experienced on seeing Cadance again. "You're evil!"

"Only if you pay me." Chrysalis strutted as she walked around Twilight, admiring every inch of the unicorn. "You had quite some fun with my pet last night. Maybe I should punish you, too?"

Yes, Twilight thought, Punish me, I've been bad. It took a second for Twilight to realize she hadn't said the words. She shook her head and stomped a hoof down to reassert herself. "You did something to my brother."

The words confused Chrysalis. She couldn't reconcile them with Twilight actually knowing what was going on, and they didn't seem to be in the spirit of the game they had played the previous night.

A touch of panic hit the changeling queen. "I have just the place for you." The decision was easy. The game would be twisted a little, but she hoped her employer wouldn't be too upset about it.

Twilight stared as Cadance's horn flared bright green, and fire started to rush up around her. Circled by towering flames of sickly light, she trembled, and was suddenly gone.

"Crap, crap, crap." Chrysalis stomped around in a circle. The wedding would be in barely an hour, and the script was so far off the rails that there might not even be rails anymore. "I hope I don't lose my bonus!"

"My Q-Q-Queen." Shining's throat trembled. He had just an hour before the wedding was due to start, and despite that Chrysalis had confronted him. She had broken the previous "conditioning," with the aim of "making him hers forever."

Looking at the dark shape of the changeling queen, Shining Armor slid deeper into his role. "Y-You have everything you want. Please let my Cadance go. I'll do anything!" He dropped to his belly before Chrysalis, groveling.

"Anything?" Chrysalis looked down at the prince-to-be. The sight of him abasing himself before her made her shiver with power. But there was more than just power—Shining Armor loved doing this. Chrysalis licked her lips. "Service your queen, show your obedience, and you may choose one pony to survive this day with their mind intact."

"I…" Shining crawled forwards, pressed his snout to one of Chrysalis' forehooves and licked the hard chitin. "I will be your pet, your toy, if you will leave my Cadie be." He returned to licking, and his tongue worked up and into one of the holes in Chrysalis' leg.

"Lift your eyes, my toy prince, gaze into my vision and let me have all of you." It was a minor effect of magic to make colors swirl in her eyes, minor and completely meaningless. Nonetheless, Chrysalis made the glowing patterns swirl, and met Shining Armor's gaze when he looked up.

Shining stared into the pattern. He felt his mind numbing, his will surrendering, and he gave a little moan of bliss as the "hypnosis" stole everything. "My queen. Command me, and I will do as you will."

"I want you to fertilize my eggs. You will be the drone that may feed my loins. Mount me, toy-prince, and seal the doom for your entire species!" Chrysalis stepped back and used another charge of her magic to make Shining's eyes glow a little. The soft green pulsing looked delightful, and was completely meaningless—outside the scene.

Feeling his queen's power in his mind, Shining nodded and stood up. He and Chrysalis had done all sorts of things over the days leading up to the wedding, but this was the first time she would let him ride her.

Shoving his forequarters up, Shining landed firmly on Chrysalis' rump. His queen was bigger than Cadance, physically, and it made lining himself up with her a little troublesome. One thrust, two, then a third failed.

"You really are pathetic." Chrysalis heaped disdain on her words, energized her horn, and took matters into her own magic. Wrapping Shining's shaft in green fire, she lined it up with her vulva. "Now, you useless—" The rest of her words turned into a squeal of pleasure.

Shining Armor lanced forward, shoving himself deep into the changeling queen with a firm thrust. His body was a machine of muscle, and it was already programmed for its task. With a groan of bliss, Shining couldn't have stopped his hips bucking if he had wanted to. "You-You have control over my body, my queen. Please be gentle…"

"Gentle is for colts and their fiances. I want drones, pet. Fuck me. Fuck your QUEEN!" Chrysalis was the queen of changelings and dirty talk, and she was committed to both. Each stroke of his shaft, so long that it felt like he was shoving a leg into her, made Chrysalis squeal a little louder. Her body rocked forward and back, and like Shining she felt out of control.

"I can't stop." Shining shook his head in disbelief. "I can't stop fucking you. Please, let me go!" He guided his hips—now with the driving thrusts of a power-hammer—into Chrysalis' rear over and over. Each slap of his groin against her plot confirmed the dedication to the fantasy that Shining maintained. "Please let me stop…"

"Give." Chrysalis arched her spine and buzzed her wings in bliss. "Me." Arching her head back, she stared up at the ceiling. "YOUR CUM!" Squeezing down as he thrust in did just what she hoped. The long strokes turned into frantic, erratic bucks, and Shining unloaded into Chrysalis' body.

The release of his seed triggered Chrysalis' own climax, and together they screamed in mindless, chemical bliss. Again and again his shaft exploded, flooding and filling Chrysalis, and the rush triggered her body to produce eggs. A lot of eggs.

Shining collapsed on his queen's back. He was still unloading, still filling her. "I can't stop—can't stop cumming. What are you doing to me, my queen?"

Familiar with stallion biology, but wanting to play up the game, Chrysalis practically purred as she rode through her orgasm. "My body is irresistible to ponies. Even now you can't stop yourself from becoming addicted to my pleasure-inducing musk. Fall, toy-prince. Fall further into my clutches!"

With a huge, silly grin on his face, Shining Armor nuzzled Chrysalis' withers. "This is so awesome. Was any of that true?"

"It was as true as you make it, Shining Armor." Chrysalis kept her cards close, not showing her hoof at all.

Landing on her plot as the strange teleportation spell ended, Twilight looked around the crystalline cavern around her in amazement. Just a second ago she had been staring into the face of the monster trying to steal her brother away, and now—she had no idea where she was.

"Twilight?!" Princess Cadance had spent over an hour getting ready. She had her feathers all ruffled, her fur stained here and there with dark patches, and a tiny smudge of shadows on her cheeks. Her mane and tail were—with extreme care taken not to ruin either—disheveled and out of sorts. Her look was perfect for her knight in shining armor to come racing down and rescue her.

Instead of Shining Armor, however, Cadance had Twilight Sparkle. "What are you doing here?"

"You!" Twilight had had enough. She jumped back a few lengths, and started charging her horn with magic. At the last second, Twilight flexed her power to render the bolt into a stun, and fired at what she thought was a monster.

Cadance was almost too surprised at the attack to put a shield up. "Twilight! Stop!" She dismissed her blue shield and pointed a hoof at her chest. "It's me, Cadance!"

"You're not the real Cadance! You're just using that form to—to do naughty things to my brother!" Twilight pawed at the ground with a hoof, and started charging her magic again. She wouldn't be caught out by a shield this time.

"Sunshine. Sunshine. Ladybugs awake." Cadance knew there was only one way to prove to Twilight who she was. Cadance had given Chrysalis an extensive description of how to act the part of Mi Amore Cadenza, but she hadn't included anything about "foalsitter Cadance" in it. "Clap your hooves and—"

"... do a little shake. Cadance?!" Twilight let her magic flow away. She stared at one of her best friends growing up, and collapsed to the floor. "I found the—the monster seducing Shining Armor last night, and she looked just like me, and instead of stopping her I started clopping, and then when I saw Shining hanging out I couldn't stop myself from clopping him too, and then I—"

Cadance had resorted to the tried and true way to silence one of Night Light and Twilight Velvet's children, and shoved a pink hoof in Twilight's mouth (hey, it had always worked on Shining, when she hadn't just used a gag that is). "Twilight, whatever it is, did you hurt anypony?"

The question, and the hoof in her mouth, gave Twilight something to think of. She shook her head.

"Well, nopony got hurt, that is good. Next time you want to play with Chrysalis and Shiny, you really should ask first." Cadance smiled at Twilight's shocked expression, but her own features courted shock suddenly.

Hesitant at first, Twilight's tongue had sought out Cadance's hoof all on its own. One stroke, then another. Twilight's lips closed a little firmer around the pink hoof, and she gave a little suck on it.

Cadance almost moaned at the naughtiness of the act. "Twilight, you seem to be enjoying that and—and I might be too—but I have a wedding to stop." The licking was insistent, teasing, and Cadance had been without any excitement since Chrysalis had started the little show.

Twilight wasn't herself. She could easily explain everything away as this not being her in control. Surely the monster had used its mind control on her, too! She closed her eyes and murmured around Cadance's hoof. Her tongue found ever crevice in the soft frog under the hard outer hoof, and Twilight—just like the previous night—sat down and leaned to the side.

"This how it is?" Cadance was the princess of love, and that purview expanded a little beyond simple love between two ponies. She could feel waves of pleasure sloughing off Twilight Sparkle. "Lay down, on your back." She moved with surety, pushing her fiance's little sister to the ground and rolling her onto her back.

Keeping the hoof in her mouth, Twilight didn't resist the physical imposition. Heat radiated from under her tail, and without a thought she reached back and started stroking.

"No. You don't get to do that." With her magic, Cadance pulled Twilight's hoof back from the unicorn's nethers. "That is mine."

The hoof leaving her mouth made Twilight moan in loss. She looked up at Cadance. "What is this? Why am I... " She tried to reach for her vulva again, and again was stopped. "Please? I need—"

Cadance cut Twilight off. "Your needs are noted. If you want this to stop, tell me." It was the first and last negotiation Cadance would give before stepping over Twilight Sparkle. Lowering her body, Cadance soon pressed her belly to Twilight's.

The pressure along her body had Twilight's blood singing in lust. Cadance was facing the opposite direction, which put something magical right before Twilight's face. She could have said no, she could have told Cadance to stop, but Twilight Sparkle just wanted to eat her big brother's future wife out.

"Oh yes you naughty mare. Eat your princess out!" Cadance's love for dirty-talk asserted itself. She had to lean over a little to find Twilight's own nethers, but when she did they were well prepared.

Twilight froze in pleasure. The tongue that found its way down her slit paralyzed her in bliss. She had played games with her friends before—it was part of being friends, after all—but there was something entirely different about having the princess of love eating her out that caused previous encounters to pale by comparison.

Cadance got her second lick along Twilight's damp folds before the thinky-thinky part of her brain sparked, reminding her that she had a wedding to interrupt. "We—We're definitely going to finish this another time."

Whining in need as Cadance stood up, Twilight tried to grab and pull Cadance back down atop her. It almost worked: Twilight held onto Cadance's butt just as the alicorn flapped her wings. "Agghhh!"

Realizing her almost-lover was coming along for the ride, Cadance wrapped her forelegs around Twilight. "Hold on!" She pumped her wings, circling up the huge cavern towards the entrance to Canterlot Castle above.

Cadance only got halfway before she felt an inquisitive nuzzle at her vulva, then a lick. "Twilight! I'm trying to f-f-fly!" But her admonishment seemed to mean nothing. Each flap of her wings was a struggle now, and she groaned as Twilight proved to be quite the stimulating limpet.

Luckily for Twilight, she couldn't look down. The drop to the crystals below would have broken her mood, and her mood right now was to eat alicorn pussy. She ignored everything but the winking, leaking vulva, and her quest to make it wink and leak a lot more.

Dropping to her hooves on the path leading to freedom, Cadance wobbled a little and let out a moan. "T-T-Twilight! I need to stop the wedding before Chrysalis marries my Shiny!"

Chrysalis was getting nervous. The rails were bent and broken, and the railroad of a wedding was plowing along with nothing to guide it. Cadance was meant to have been rescued by Shining (or in this case Twilight) by now, and should have crashed into the room and "stopped Chrysalis."

"May we have the rings, please?" Princess Celestia wasn't sure what was going on, but Princess Cadance was unusually jumpy, while Shining Armor was completely calm. She looked at the pair with suspicion, but there was nothing concrete to call off the wedding over.

Standing to the side, Flash Sentry held out the cushion holding the two horn-rings, and bowed.

Chrysalis was in a panic now, and looked around in the vain hope that Cadance would come crashing through the doors at the end of the long hall. As Princess Celestia floated the rings closer, her mind raced. "Droit de la princesse!"

The audience had already been holding its breath. The big moment was upon the bride and groom, and emotions were high. Princess Celestia was first to react to Chrysalis' outcry. "Pardon?"

"Droit de la princesse!" Chrysalis looked left and right. "The… uh… law." She reached out with a hoof and pulled Shining—who was looking equally confused—close to her side. "The ruling princess must, as her right, claim her right to the… uh… groom!"

"That doesn't sound like a law I would pass." Confused still, Celestia tapped her jaw in thought. "When was it enacted?"

Chrysalis had to work quick to build a lie that was both believable and wouldn't get tested. "Last week… It was all official. You could go check or we could just get it over with?"

Princess Celestia gave a sigh. It had been a long time, and she certainly couldn't say Shining Armor didn't look quite the fine stallion. "Very well. As per Princess Cadance's request, I claim droit de la princesse."

The relaxed nature of the wedding seemed to shift. The crowd was surprised by the turn of events, but everypony watched with excitement as Princess Celestia turned—slowly and with an air of sensuality she had never shown before—and presented her flowing tail to Shining Armor.

"Nail your princess, Shiny!" Twilight Velvet shook her hoof in the air, a huge grin on her face. Leaning to the side, she beamed eagerly at Prince Blueblood. "That's my colt!"

Shining didn't even hear his mother's excited call. He stared at the shifting colors, and expansive white plot before him. "Uh…" His whisper was low enough that only one other pony heard: Chrysalis. "Are you sure I should—"

Chrysalis nodded. "You will fuck this princess for your queen, won't you?" She watched as the words inspired a flood of excitement in Shining Armor's eyes. He nodded back to her. "Plow her, make her weak for you."

Turning back on Celestia, Shining Armor surged forward.

A gasp ran through the hall as Shining got up on Celestia. His first thrust earned another gasp, and then hitting his mark, a sigh. All the sounds came from Princess Celestia. It had been a very long time.

The feel of a stallion on her, in her, drove Celestia's mind to a base delight. She moaned out as Shining pulled himself fully onto her. A loud slapping sound echoed through the hall when his bucking hips first connected with her rump, but it was just the first of many. "Yes! This is the—the best law ever!"

At just that moment, Princess Cadance battered down the doors at the end of the hall. She had been prepared for a lot of eventualities, up to and including Chrysalis and Shining actually being married, but her fiance screwing Princess Celestia was not on the list.

Staring up at the dais where her beloved was giving a particularly good bucking to Celestia, Cadance was forced to shift her hips. She still hadn't managed to detach Twilight Sparkle. "Stop! She's an imposter!" Her final word came out with a lot more moan than was traditional, Twilight was apparently well versed in the art of cunnilingus.

"It's too late!" Chrysalis was off script, off the rails, and now apparently out of her mind. "My mind-controlled minion will soon impregnate Princess Celestia with his—his mind-control seed, and Equestria will be MINE!"

The pronouncement earned gasps from around the hall. Gasps, and the continued slapping of Shining Armor's hips against Celestia's rump. So deep in his little sexual fantasy, Shining was blind and deaf to anything but the need to carry out commands.

Stepping down the dais, Chrysalis shed her Princess Cadance disguise and revealed herself in all her glory. "You can't stop me now!" Her eyes blazed with power.

Steeling her heart, Cadance stepped forward with her wobbly legs, and only moaned a little. Standing before Queen Chrysalis, she stared the changeling in the eyes. "You cannot claim Equestria until you have bested all its princesses!"

The fire and passion in Princess Cadance's words drew gasps from everypony present, and moans from Celestia and Shining (although that may have been due to the rutting). Chrysalis lit her horn and plucked Twilight Sparkle from where she was still feasting upon royal vulva. "Little pet, bear witness to the outcome of this battle, for it will decide the fate of the entire world."

Whining at her loss of hot princess to eat, Twilight wobbled and lay on her back. She watched Princess Cadance and Queen Chrysalis circle each other for a few seconds before something shoved into her.

Rolling her eyes at the mare to her side, Lyra shook her head. "Bon Bon, I am hardly going to leave my friend hanging." With her magic formed into the shape of a golden dong, Lyra started shoving the shape deeper into Twilight.

"There is nowhere for you to run, Cadance." Chrysalis, back in her natural anatomy, extended her ovipositor. The shape wasn't just slightly phalic, the mock-dong was thick, meaty, and pulsing with each thud of Chrysalis' heart. Her body had been flooded with stallion seed earlier, and combined with the eggs she carried had quite the load to gift Cadance. "Pick your position."

Cadance moved faster than Chrysalis could react. Born a pegasus, Princess Cadance didn't rely on magic to shove Chrysalis onto her back, she used brute force provided by her huge wings. "This one."

The motion of pegasi was always graceful—so long as they weren't crashing—and so Cadance brought her hips around so that she straddled Chrysalis, and delivered her plot to the changeling's groin. The spike of pleasure as she impaled herself on the throbbing ovipositor threatened to overwhelm Cadance, and she struggled to maintain mental coherence.

"Your—Your plan was a good one, princess, but you neglected one little fact: changeling queens exude lust-inducing drugs from their ovipositors. Each second you have me within you, you fall deeper into my control. Fight it, please, I love it when an alicorn struggles!" With the princess of love bouncing on her groin, Chrysalis knew her ploy wouldn't succeed, but she was sure going to have a good time anyway.

It can't be true, surely? thought Cadance. "You're bluffing." Each time she rocked her hips the swollen hunk of ovipositor pulled out and shoved back in. "You have to be bluffing…" Despite her brave words, Cadance felt her climax rushing toward her.

Chrysalis reached up and held Cadance's sides with her forelegs, trying to guide the princess into a slower pace. Cowmare was not a favorite position of Chrysalis', but she was quickly warming up to it. "Yes, just slow down, let my changeling poisons seep into your mind and wash away all your needs. There is only one thing you need now, princess of eggs…"

Cadance shook her head. She refused to be beaten, and despite the slower pace started to squeeze with her body, massaging Chrysalis' ovipositor for all she was worth. "Eggs? Oh yes, I'll take your eggs, your hive, and everything you have."

"You… You…" Chrysalis' eyes widened as the princess expertly massaged her pseudo-dong. She made a soft whine, and felt the first rush of pressure unleash inside her. "You win…"

As the first explosion of heat rushed into her, Cadance rocked back and squealed in glee. "I win!" Egg after egg was sprayed, shoved, and forced into her body. She hit her climax seconds after Chrysalis, but it was after. Squeezing her eyes closed, magic erupted from Princess Cadance's horn and bathed everypony present in pink light.

On the dais still, Shining Armor hadn't been given permission to climax yet, and was in a world of agony holding himself back. He kept his hips going, kept plowing Celestia's fertile field with his shaft, when the magic hit him.

Renewed with power and lust, Shining stood proud on Celestia's back and shoved himself into her clutching depths, and exploded. "For Cadance!"

The rutting was coming to an end, or so Celestia noted. She had been shoved into a happy, lust-filled rhythm by Shining Armor's repeated bucking, and now that he had finally delivered his seed she squealed in release. Heat rushed up through her whole body, and Celestia felt like she was the sun itself in the moment of perfection.

The royal couples hadn't been the only ponies to be making the most of the wedding. Around the hall nearly every guest had fallen and was copulating with another. Everypony froze, however, when Princess Luna stomped into the room. "Hello everypony, did I miss anything?"

Panting, sitting on top of Chrysalis and held upright by sheer force of will, Cadance looked up at Princess Luna and chuckled. "Only the best wedding ever." She leaned forward, and pried Chrysalis's long shaft from her body. Staggering to her hooves, Cadance gave a sigh. A simple glance at the princess of love's belly would show it to be a little swollen.

Chrysalis was a defeated bug, but that was the objective. The plan had flown out the window sometime around when Twilight Sparkle had helped her get Shining Armor off. She loled her head back and watched Princess Cadance wobble with a belly full of changeling eggs. "I am defeated…"

Shining Armor, done with his duty under a startlingly new law, whistled. "Cady?" When his future wife's head spun around, he saw weariness turn to excitement. "Can we get married now?"

Cadance didn't walk, she trotted with high, prancing steps. Reaching the dais, she took the steps as quickly as she could and pressed her lips to Shining's. Swelling love wrapped around the pair, and bright pink light sprayed out, renewing everypony's stamina.

"Of course." Cadance nuzzled up and down Shining's cheek. "How is Princess Celestia?"

"Ridden hard, put away very wet." With the influx of energy, Princess Celestia regained her hooves and, on wobbling legs, made her way over to stand before Shining Armor and Princess Cadance. "Where are the rings?"

"I found one." Princess Luna, having figured out things were at least moderately under control, trotted to the front of the room with a golden, single-gemmed ring.

Chrysalis, somehow, had landed on the other. When she stood up, the ring jangled into one of her leg-holes. "I have the other…"

"Queen Chrysalis. Chryssi." Cadance turned to look at the changeling. "Would you bring it up here so I can thank you for helping make this the best wedding ever?"

Chirping in excitement, Chrysalis was half drunk on the love pouring through the room, and finally made it up to the front to stand beside Cadance.

Flanked on each side by a dark, pony form, Shining and Cadance turned their eyes back to Princess Celestia. "Before any other interruptions, laws, invasions, impregnations, or—or anything." Celestia was a little distracted by how much her nethers ached to be filled again, and decided to just skip ahead. "I now pronounce you mare and colt."

Chrysalis leaned to Cadance's ear. "Shouldn't that be 'and stallion'?"

With a ring on her horn, Cadance barely heard the changeling's question over the thudding of her own heart. Leaning forward, she kissed Shining again, and a roar of approval rose from everypony in the room.

With the newest royal couple walking back down the aisle, Princess Celestia got a little closer to Chrysalis. "Shining's status as a stallion,"—she began, kicking a back leg in sympathy with her aching genitalia—"will need a few more times to make sure of."
