Pink Empress Princess Pony Mi Amore Cadenza knew she was in trouble.

As flippant as she'd been when Largest Boss Horse Princess Celestia and smallest purple princess pony Twilight Sparkle were entangled by frisky tentacles, she knew that Shining Armor's prank was going to have serious repercussions. Because she was the one who actually made the frisky tentacles, and then set them up to capture horse princess Twilight Sparkle, most of the repercussions would be hers.

She sighed as she placed the gag bit in Shining Armor's mouth.

There was no point in lying to the Princess. As Largest Horse Boss of Equestria, Celestia was no foal. She'd seen it all, and probably done most of it herself. Empress Cadence slipped the crownpiece over her horse husband's ears and buckled the throatlatch as she contemplated her next course of action.

After buckling the noseband and attaching the martingale, obviously. She knew it wasn't exactly proper to train with a martingale and gag bit, but her horse prince husband absolutely could not manage to hold his head at the correct height on his own. She clipped the reins to the bit rings, and then tied them to the saddle so he'd actually be in a position that at least resembled being properly on the bit for once.

"Ten meter circle, then volte, then pessade, Shiny," she said. She was determined to get to pirouette before the end of the week, whether her horse husband liked it or not.

She kept an eye on him as she turned again to the problem with the Largest Horse Princess of Equestria. She'd have to do something. Maybe it would be easier to go through an intermediary. An intermediary that, if her suspicions were correct, would be inclined to suggest a lenient punishment for her part in the prank.

She began to compose her letter before a linebreak indicated a scene change.

Twilight Sparkle, pony horse princess of Ponyville, scanned the letter she'd just received by very private courier. Her abnormal horse brain let her read letters and other readables with exceptional speed, so it took her a fraction of the time it will take you to read the following words:

Twi Twi my numba one (1) hussy:

What up, slut? You know I'm just playin,' my street bitch! *wink* This is yo sexy sistah (in law) Cadenze and I wanna know if you can do me a solid, boo.

Shiny sez hi

Number 1 Thundercunt,

Cadenze

xoxoxoxo

All of the "i"s were little hearts, and there was a liberal application of glitter. Empress Cadence's signature was in some kind of puffy glitter paint.

Twilight applied her horse brain to the letters she was reading. She applied her horse brain to the problem they presented. Ever so slowly, a smile began to spread across her nice horse face, like the syrup Spike had just spilled was spreading across the kitchen tiles. Spike would never tell her about the syrup, and later on she would want some with her pancakes and not understand why it wasn't there.

There was a line break to indicate that the point of view was no longer focused on the highly abnormal horse princess Twilight Sparkle.

Magnificent mini boss horse Princess Luna of the Night stretched her long limbs, arching her back, spreading out her wings, and yawning in a potentially unPrincesslike manner. She'd just got done messing around in the dreams of one of her sister's students' young siblings. The reason she'd be doing that went something like this:

"DEAREST SISTER, WE ARE FEELING RATHER JEALOUS," Miniboss Luna said in a flashback to Largest Horse Boss Princess Celestia.

"Luna, inside voice please. Also, what exactly are you jealous of?" Celestia replied, looking over her own gorgeous butt at her sister.

"SISTER," Luna said before switching to her inside voice, "You have a star pupil and her wonderful friends as your own personal concubines-"

"They aren't my conc-" Celestia began before Luna soldiered bravely forward at an increased volume.

"But we entirely lack such students/concubines and have been repeatedly informed about the supposed impropriety-"

"Luna, they're just my student's friends," Celestia interrupted, "and my friends, and you can't go around just forcing other ponies into concubi-"

"AND SO," Luna continued, "We would like our own 'students' and 'friends." She winked in an excessively slow fashion. "And have decided to help the siblings of your 'friends' in Ponyville with any sister problems by messing around in their dreams."

"Luna I really don't-"

"The crippled pegasus too."

"Seriously Luna this isn't-"

"Thank you sister, we knew you'd understand that we are most qualified to dispense wisdom on sisterly jealousy to younger siblings!" And then mini princess horse boss Luna of Dreams flagged her tail and whickered as she trotted out of the room. Celestia rubbed her temple with her hoof and closed her eyes.

Luna flapped her wings and stretched the other way, pushing out her chest and extending her back legs. Her royal back made a few little pops, and she smacked her lips and yawned again as a guard came in with a letter. He looked vaguely uncomfortable as Luna began to preen, clearing his throat to make sure the Princess actually knew he was there as she slid each long, dark feather between her very mobile lips.

He was carrying a letter, and the second time he cleared his throat she plucked it out of his mouth with her magic, floating it slowly across the room as she finished nibbling on the tip of her last secondary covert feather. The guard yelped as her magic slapped him in what she considered to be a light, playful manner on the hindquarters to indicate to him that his services were no longer needed. He quickly fled the scene.

"From Princess Twilight Sparkle," mini boss Luna said to herself, straightening up and walking slowly from her bedroom into the solarium where her sister was just having her morning tea. The table was set for two, with an attendant filling the second cup as soon as Luna entered.

"Dear Sister," Princess Luna said as Boss Horse Celestia looked up at her, not pausing in her delicate sip, "your Faithful Student proposes a very interesting solution to both the issue of her continuing lack of Princessly Authority and the issue of appropriate action against Princess Mi Amore Cadenza of the Crystal Empire."

Celestia only raised one perfect eyebrow to indicate interest as she continued her sip, totally not making the slurpy noise.

"I am very inclined to allow her the opportunity," Princess Luna said, passing the letter to her sister as she began to sip her own cup of tea.

Princess Celestia nodded, continuing her long sip, and raised her other eyebrow to indicate increased interest as her eyes scanned the page. She set her empty teacup down and delicately smacked her lips.

"Eh, why the fuck not?" she said before the line break indicated a change of scene.

"Okay, now over there," Twilight pointed with the short whip and Princess Luna made a half-pass with perfect balance, engagement, and collection, moving near the doorway of the largest royal bedroom while keeping her large, dark eyes fixed on princess Twilight Sparkle. Twilight couldn't keep her tail from swishing up behind her, although she quickly forced it down through sheer willpower.

"And, p-Princess, just turn slightly and tail just slightly to the right," Twilight stammered as Princess Celestia performed an absolutely flawless quarter turn on the haunches, leaving her tail slightly bent away from center. Twilight could glimpse the very side of Princess Celestia's exquisite horse labia. She pressed her backside against the wall to pin her tail against her butt as she felt a trickle of fluid drip down her leg. Princess Celestia was collected and calm, looking over her shoulder at her pupil who was furiously blushing just beside the door.

"Oh, ok your majesties," Twilight said, "Any minute now."

Pretty much right after she said that, Princess Empress Mi Amore Cadenza busted through the door. She performed a very passable pesade, excepting, of course, that she waved her forehooves around. "What's up lay-dees!" she squealed, lifting up her neon green shutter shades to wink at the Royal Sister horses. When all four feet were on the ground, she turned slowly, looking for Twilight and continuing to address the room in general. "I'm kidding! You know I love you C-lest, and Luna you lookin fiiii-ine!" She gave another exaggerated wink and ran the tip of her tongue along her upper lip.

"Where's my little sister in law?" she asked, right before she spotted Twilight and used a non-canter intermediate gait to approach the smallest horse princess.

Luna's magic wrapped around Cadence's rear hooves and jerked her hindquarters straight up into the air, slamming the intermediate horse princess Empress's face into the marble floor as her front hooves skittered out from underneath her. The shutter shades bounced across the white and gold tiles and slid to a stop at Twilight's hoof. "I think I bit my thung" Cadence said just before Celestia's magic grabbed her mane, wrenching her head to the side and shoving a mullen mouth bit between her lips. The buckles were fastened with quick, expert motions as Twilight began to slowly walk toward, her, the smaller princess's tail immediately flagging. The shutter shades snapped in half under her hoof, one side spinning crazily across the tiles.

"I'm here to enforce your punishment," Twilight began, her cheeks burning. "I need to show my Lo-" She shook her head. "Mentor that I'm ready to assume my princessly duties by proving that I'm totally responsible for things." Cadence licked at the drop of blood on her bottom lip. From her vantage on the floor, she noticed several drips of moisture falling from Twilight's hindquarters. She also noticed that Twilight was looking right past her, at Celestia's eyes, or maybe her butt. Whichever really.

Twilight bent down until her lips were mere inches from Cadence's ear. "Don't worry, sister," she said, "I got your message..."

"Loud," she ran her tongue along the rim of Cadence's ear,

"And," her tongue traversed Cadence's cheek and muzzle,

"Clear," before ending on the small cut just on her bottom lip. Cadence could taste her own blood on Twilight's tongue. Like any horse that didn't have a frighteningly abnormal brain, she became very, very concerned.

Then there was a line break to show that some time had passed.

Fortunately, they were all still fucking, although a great deal of time had passed. The air was thick with the scent of horse pussy, and the pussies of all four princesses did not smell like clouds or lavender or marshmallows or whatever. They smelled like pussy. Wet, equine vagina. The distant, second place runner-up for strongest smell was sweat. Crystal Empress Mi Amore Cadenza could also smell her own blood sometimes. Currently, she could smell Medium Boss Horse Luna's asshole quite strongly, because she was forcing her tongue as far inside of it as she could on Twilight's orders.

Smallest Horse Princess Twilight was pressing her hips against Cadence's, both of their legs splayed and their horse parts rubbing together like two doughnuts trying to make out. The constant wet slurps were interspersed by noisy belches of fluid from Twilight's frequent horsgasms.

The Smallest Horse Princess of Ponyville wasn't looking at Cadence, though. Her face was pressed against Celestia's pristine white chest, Twilight's small pony hooves running very gently along Most Perfect Horse Boss Celestia's forelimbs. Twilight had a lock of Celestia's mane in her mouth, somewhat muffling her groans and screams.

Celestia herself was all perfect poise and composure. She looked down at her most abnormal student with gentle eyes as Luna massaged her glistening white pussy in slow, circular motions with a dark forehoof. Luna's head was laid across her sister's back, a faraway stare and a silly grin clearly indicating how much she enjoyed Cadence's tongue-colonoscopy. Luna's face and chest were damp with her sister's secretions and she wasn't so much preening Celestia's feathers as she was transferring girly spunk from her face onto her sister's wing. She'd repeatedly sprayed her own mare splooey all over Cadence's rather muscular neck and chest, and Cadence and Twilight's hips and crotch areas were both totally inundated in pungent horse dribble. All four bodies squeaked slightly with the motion of their sweaty flesh over the tile. It was basically going to be a total disaster for somebody else to clean up.

Twilight came again as she pressed her forehead and nose into the area where Celestia's neck met her shoulder. Her pussy belched and farted like those mud pots at Yellowstone National Park and it made little geysers of her mare goop. She'd cum so many times that she'd lost the ability to think coherently, and she cried freely and came again just a little as the smell of Celestia fully inundated her highly abnormal brain. She made a little noise like "guh" around the thick hank of celestial mane in her mouth, and in a few minutes she would slide into the blissful unconsciousness of a pleasure coma.

Luna wasn't too far behind her. The feather she'd been chewing on slipped free of Celestia's plumage and her hoof went limp as her face sort of settled into the divot on her sister's back right where her buttcheeks started.

Cadence worked her tongue free, looking rather ragged. Her flanks were covered in bright red welts and her pussy was positively battered (the reader can use either definition of "battered" depending on how they like their pussies.) A bunch of her own loose feathers were glued to her mane with various fluids, and she slumped against Luna's rump with an exhausted sigh.

Celestia looked like she always did, regal and perfect, although there was a hint of blush coloring her cheeks and also her mare vagina. She smiled kindly at Cadence.

"I guess that's that, then." she said. "You're off the hook."

Cadence wiped her mouth on a part of Luna's tail. "I got a question for you though," she said, glancing at the two passed out princesses sharing floorspace with them.

"Shoot."

"So, uh," Cadence glanced around again, "What's up with Luna and the butt stuff?"

"What's her name backwards?" Celestia said, winking slowly.

"A - N - U - L?" Cadence said, tilting her head to one side and smearing a streak of dribblings across Luna's hip.

"What would it be if her real name was Lana?" Celestia said, winking the other eye very slowly.

Cadence slowly reversed the letters in her somewhat-abnormal-but-not-nearly-as-abnormal-as-smallest-horse-princess-Twilight-Sparkle's-horse brain. "OOOOoooooh!" she said. "Is Lana her real name?"

"Not really," Celestia said, kissing Cadence on the nose.

"You know," Cadence said, "I'm glad I got to see what everypony's p-cess cunt tasted like. Because they were all different."

"Yeah," Celestia said. "Pussies are pretty awesome. I guess Twilight's pretty OK too. Maybe she'll make it as a princess after all. Although realistically I should probably just keep her around here for a while and sex her up on the downlow."

They probably did some other stuff, but the reader was forcefully inserted into a scene inhabited by Shining Armor, taking place some time later and indicated by a line break.

"Look darling! I've been practicing volte and pessade all day and I'm getting really good!" Shining Armor said around his bit as his exhausted wife stared at him through her taped-together shutter shades.

"That's great, boo boo," Cadence said, focusing mostly on the notes she was taking in her marbled notebook titled "Love Experiments." The ice pack wedged firmly between her hind legs slid down a little.

"How did your thing go?" he asked, almost actually on the bit for once as he ran through the routine again.

"They fucked the absolute shit out of me," Cadence said. "Oh, and I think your sister and Cee-Lest are straight up fucking now." She sighed and waved a forehoof in Shining Armor's general direction. "I am way, way too tired to actually ride you like the little bitch you are tonight. How bout a hoofy-jay or something?"

Under his breath, Shining Armor made the same sound that his sister made as she woke up a little and discovered she was nestled between the hooves of her sleeping mentor, Celestia. It was a little quiet horse noise that sounded like "Score."

Author's Note

I was determined to finish it before the next season came out.
