After getting back from the party, Discord had planned on turning Celestia and Luna back to normal. But at the last minute, he decided that he liked bossing them around too much to give it up. He wanted to make it a permanent arrangement.

So instead of returning them to normal, Discord deepened their brainwashing. He lowered Celestia and Luna's intelligence to be on par with that of animals. He made them think that they were wild, feral ponies, whom he had tamed, trained, and adapted as his pet. He made them recognize him as their owner and master, being completely obedient to him. He spent hours adjusting and conditioning their minds and bodies. Altering their logic and sense of self. Rearranging their muscle-memory and reflexes. He removed all traces of royal or civilized life from them. By the time Discord was done with the Royal Sisters, Celestia and Luna no longer existed. They were now renamed, as Sun Butt and Moon Butt, Discord's pet ponies.

But Discord didn't want them living double lives as princesses. They shouldn't have to put up with those stresses anymore. So Discord cast a sell on all the ponies and other creatures across equestrian. He made them all think and the Royal Sisters had retired from the throne and moved far away, leaving Twilight Sparkle in charge. And nopony ever questioned why.

Discord then moved to ponyville with his new pets, as a permanent resident. He moved his house to where the Golden Oak Library once stood, and made himself at home. Surprisingly, Discord and his pet were quickly accepted as neighbors.

Twilight and friends were, at first, shock about Discord's pet. They had never heard of feral ponies. But they believed him, anyway. And grew to love the animal friends.

Twilight being able to study the rare specimens. Fluttershy quickly made friends with them. Rarity loved to design pet fashions for them. Pinkie Pie, of course, threw a party, Rainbow Dash loved to race them. And Apple Jack loved it when Discord let her use his pets for farm work.

Overall, everypony was happy with life like this. And nopony ever questioned why.

______________________________________________________________________________________________________

Five years later...

It was the 5 year anniversary of Discord moving too Ponyville. To celebrate, Twilight and friend had planned a day of fun together with him. And it started with a pet playdate in the park.

At this time, Discord was sitting in his kitchen, sipping his coffee. He read a newspaper as he did. While reading, he felt something bump his leg. Discord looked to his side to the source. It was none other than his pet. Sun Butt and Moon Butt.

They sat together, side by side, in their pet bed looking up at their master. They were wearing their house attire. A plush toy crown each of their heads. And matching slippers were on each of their hooves. A magic suppressing horn wrap, on their horns. Sun Butt wore a collar that aid "Boop the Sun". Moon Butt wore one that said "Snuggle Moon". And they both had their tongues out, panting.

Discord knew what they wanted. He snaked his tail over to the counter. It picked up a bowl of kibble, that he had poured earlier. And it set the bowl in front of the cute little poines. Discord then snapped his tail. A plate appeared beside the bowl in a flash of magic. On the plate were a couple of blue flowers, specifically poison joke.

Discord watch as they eagerly dug their faces into the bowl together. They then each ate one of the poison joke flowers.
It never ceased to amuse him, seeing them former princesses now eating dog food. And they liked it. Discord grew slightly happy watching them eat. Even more so by the fact that they were also eating poison joke.
Discord had once told them that it was special treat that they could only eat when he let them. He sometimes fed it to them when he wanted some cheap amusement.

After they were done eating, Discord noticed the time. It was only around 7 in the morning. And he didn't have to meet the other at the park until 9. But he still had to leave soon. He had made arrangements to meet Rarity in the early hours to pick up a special surprise for his pets.

Dsicord put his paper down on the table. He snapped his fingers and made two leashes appear in his lion paw.

Looking at his pets, Discord said “OK, you two. It’s time for us to get going. So both of you stand up straight.”

Sun Butt and Moon Butt did as they were commanded. They got up from their pet bed and stood side-by-side in front of their master. Both of them panted as Discord looked them over. They had the far-off look of dumb animals in their eyes.

Discord said "Are you girls ready to go?"

Sun Butt and Moon Butt both replied "ARF! ARF! BARK!"

Discord smirked at this. The poison joke was making them bark like dogs. Which was only appropriate since they lived and acted like dogs. He though this was very fitting for them. Now they sounded even more like real pets. Because it entertained him, Discord decided he would leave Sun Butt and Moon Butt like this for whole day.
Discord snapped his paw again, turning his pets’ collars into leather ones. These new ones had name tags with the girls’ names on them. Discord clipped both leashes on the collars. He started to walk out of the kitchen, tugging the leashes for the girls to follow him. Sun Butt and Moon Butt eagerly followed Discord to the front door.
Discord opened the door and lead his pets outside. Upon stepping outside, the morning sun shined down upon the three. Twilight had in charge of the sun and moon for the last five year, and she was quite good at controlling them.
After admiring the sunrise, Discord looked to his pets. They were sitting by his side, panting and waiting for their master to lead them on. Discord was ready to go, so he started walking down the street. Ponyville didn’t have any paved street, they were mostly dirt paths. But Discord didn’t mind, he liked the humble feeling it gave the town. The same humble feeling that he had instilled in his pet during their training.
Discord remembered those days so well. Of course, his magic is what had made Sun Butt and Moon Butt so obedient in the first place. But Discord still had to train them how to live with him. They had to learn what few rules he had. How to do the tricks he wanted. And how to serve him like pets should.
Flutter Shy had been kind enough to teach the alicorn pets Discord’s rules. She taught them how to respond to command. What they should and shouldn’t do. And even how to mind their manners around other ponies. Discord was most thankful for how she taught them to use an extra-large litter box.
Rainbow Dash had taught Sun Butt and Moon Butt how to do tricks. From joy flying to special stunts. They flew both for fun and Discord’s entertainment. Discord had actually won several pet shows with the alicorns.
And Apple Jack had been more than happy to help instill a work ethic into Sun Butt and Moon Butt. Doscord had them help AJ with her farm chores to learn how to serve practical purposes. They would pull apple wagons and plows on a regular basis. Eventually, they got good enough to start serving Discord. Sun Butt and Moon Butt mow ran his errands, made deliveries, cleaned the house, and even gave rides to their master.

Discord remembered those day as he continued walking his pets down the street. Those were some good times. Discord looked at his surroundings and notice he was passing Sugar Cube Corner. He saw that Mr. and Mrs. Cake were already setting up their store for the day. Pound Cake and Pumpkin Cake outside playing as the parents yet about their business.
As he passed by the family, the Cakes noticed Discord and waved at him. When he came close to them, Discord stopped and face them. His pets stopped and sat by his side.

Looking at discord, Mr. Cake said “Good morning, Discord! Out for early morning walk with the pets?”

Discord replied “Good morning, all. I’m actually on my way to Rarity’s shop. Today is the 5 year anniversary of when I got my little darlings here. And me and Flutter Shy’s friends have an entire day of celebrating planned. I was taking the girls over to Rarity for a special surprise.”

Upon hearing this, Sun Butt and Moon Butt’s ears perked up. They looked at Discord and started panting. Everyone could see they were eager.

Mrs. Cake said “Oh, really. Well, congratulations on the occasion. It’s so nice to see how responsible you’ve become in these last few years, Discord. Say, I think we have a spare treat lying around for the darlings, if they want it.”

Hearing this, Sun Butt and Moon Butt said “ARF, ARF!”

Discord responded “Oh dear. It sounds like they would want it, if it’s ok with you two.”

Mr. Cake said “Not a problem! Wait one moment.”

Mr. Cake then then went into his store. Moments later, he came back out with a plate that had two cupcakes on it. He set it on the ground in front of the alicorns, who looked at it with drooling mouths.

Mr. Cake said ”Dig in!”

Sun Butt and Moon Butt looked at Discord with wide eyes. He saw what they were saying.

Discord said “Go on, you two. It’s a special day.”

With that, the alicorn pets dug into their respective cupcakes. As they ate, Pound Cake and Pumpkin Cake couldn’t help but be fascinated by the large animals. They walked over to Sun Butt and Moon Butt. The pets notice this as they ate. They crouched down on their knees. The Cake twins started petting the alicorns as the continued eating. This made the pets happy.
After a few moments, the cupcakes were gone and the alicorns stood up. Mr. and Mrs. Cake pick the twins. Discord knew it time to continue on.

“Thank you for the treat. It looks like they enjoyed it. Girls, say thank you!”

The alicorns said “BARK!”

Mr. Cake replied “Your quite welcome. And thank you for letting the kids pet them. Have a good day!”

With that, Discord signaled for Sun Butt and Moon But to follow him. He started to walk down the road again, and the pets walked alongside him. The Cake waved as he walked off.
Discord continued to walk down the street. He made his way past other shops and through the market place. As he past other ponies, everyone waved at him and gave him compliments about his pets. Every piece of praise that Sun Butt and Moon Butt heard made them blush red in the face. They were happy that they were bringing their master respect.
After walking for a few more minutes, Discord finally arrived at Cresol Boutique. Discord knocked on the door a few times.

From inside came the words “Coming, one moment, please!”

Moments later, the door opened. Rarity looked at her visitor, and was pleased to see it was Discord.

Rarity said “Ah, Discord! You’re on time. I’m glad you made it.”

Discord replied “So am I. Thank you for agreeing to meet me at such as early hour.”

Rarity said “It’s no problem at all. Things like this are what I live for. So please do come in.”

Rarity stepped aside. Discord lead his pets into the store with him. And Rarity closed the door behind him. Once inside, Rarity lead them all over to her dressing studio. There, Discord had Sun Butt and Moon But sit.

Discord looked at Rarity and asked “So Rarity, were you able to finished that special “thing” we talked about?”

Rarity looked back at him with wide eyes and replied “Oh yes! Definitely! I was up half the night putting the finishing touches. But I know they’ll love them.”

Discord said “Oh, good! Let’s not wait another minute. Show them now!”

Rarity replied “With pleasure!” in a giddy tone.

Rarity walked over to a certain by her fitting stage. She place her hoof around a rope and looked at the alicorns.

With a smile on her face, Rarity said “Sun Butt. Moon Butt. In honor of these last few years that we’ve all been friend and neighbors with you and Discord, He had me whip up some special outfits for you to wear throughout your celebrations today. So from me to you, Happy Anniversary!”

With that, Rarity pulled the rope, making the curtain open wide. When Sun Butt and Moon Butt saw what was behind it, their eyes went wide. Behind the curtain were two mannequins. And on them were two similar, but elaborate, outfits that looked to be made out of leather. Each appeared to made of two front leg stockings, two rear leg heeled boots, a leather corset, a tail wrap, a large collar, and a leather bridle.
Sun Butt and Moon Butt both started to pant rapidly, with big smiles on their faces,

The alicorns said “ARF, ARF! PRETTY, PTRETTY!”

Discord said to them “I can see you’re happy with this surprise. I’m glad. But let’s get you both dressed before we start the real celebrating. Ok?”

Sun Butt and Moon Butt replied “WOOF, YES MASTER!”

With that, Rarity stepped forward. She lit her horn and moved both mannequins over to by her fitting stage. She was ready to work her makeover magic.

Rarity looked at both pets and said “Now, Discord has also given me the pleasure of being able to groom and make you both over. When I‘m done with you two, you’ll be the eye catching, leather clad, talk of Ponyville.”

Rarity then lit her horn again. She floated a trunk out from behind the same curtain as before. She set it down right next to the outfit and flipped the lid open. On the inside of the lip was a mirror. And in the trunk itself was were two separate compartments. One stocked with grooming brushes and hair styling tools. And the other filled with makeup and other feminine products. It was obvious to Discord that this was Rarity’s “Super Beautification Kit”. Which meant she was going to give his pets a full-body hard-core makeover.

Rarity turned her attention back towards the alicorns, both still sitting and happily panting.

Rarity said “Ok, now I can only make one of you over at a time. So let’s get started. Sun Butt, Would you please get up on the stage?”

Sun Butt replied “ARF! Yes, mistress Rarity!”

With that, Sun Butt got up and walked toward the stage. Discord had taught his pets to always refer to Twilight and each of her friends as “Mistress”.
Sun Butt stepped up onto the fitting stage. Discord snapped his paw and her collar disappeared, leaving the alicorn completely bare. A clean slate for Rarity to make her over the way only Rarity could. Sun Butt stood up straight and waited.
Rarity lit her horn and levitated one of the brushes out of her beauty box. And with it, she brought out a small tube of liquid. Rarity squeezed some of the liquid onto the brush. It looked like grease. She then started running it through Sun Butt’s fur coat, grooming it sleek and shiny. Soon enough, the alicorn’s fur looked like smooth silk.
With Sun Butt’s coat slicked down, Rarity could now start dressing her for real. Rarity put the brush and tube back into the box. She then turned her gaze over to the mannequin with the outfit.
Rarity lit her horn again. Her light-blue glow appeared around the front-leg stocking of the outfit. They magically slipped off of the mannequin. She levitated them over to Sun Butt. Taking the cue, Sun Butt lifted her right-front leg first. Rarity slipped the stocking onto the alicorn’s leg. It covered the entire length of her leg Sun Butt got a chill feeling from of the smooth, cool leather clothing. She especially liked how good it felt, fitting snuggly around her leg.
Rarity then slipped the other one on her. She then magically buckled the straps on the stockings. Upon pulling them tight, Sun Butt closed her eyes, and hummed in delight. She liked the feel of the snug leather tightness. It reminded her of the collars Master Discord always had her wearing.
With that done, Rarity looked back at the mannequin. Now she levitated the rear-leg boots off it. Floating them over to Sun Butt, the alicorn took the cue. She lifted one rear leg into the air. Rarity slipped the boot onto her leg, bringing it all the way up to her thigh. She then slipped the second boot onto the other rear leg. With both on, Rarity fastened the buckles on the boots, tightly securing them in place.
Rarity took a step back at that point. Sun Butt still had her eyes closed and was humming in delight. She obviously liked the feel of the skin-tight leather. While her subject was distracted with pleasure, Rarity looked over to Discord.

Rarity said “Discord, are you sure you want their wings to be bound? They would give the outfits so much flair.”

Discord replied “No, they need to be bound. None of the other girls’ pets have wings as large as my little alicorns, here. I don’t want them feeling bad about it. Besides, it makes them look so much sleeker.”

Rarity simply said “Very well! As you wish.”

And with that, Rarity turned her attention back to Sun Butt. She levitated the corset off of the mannequin. Floating it over, Sun Butt saw it and knew what to do. The alicorn folded her wings in as tightly as she could. Rarity floatted the corset under Sun Butt’s stomach, opened it up, and then wrapped around her waist. The corset wrapped right around the wings, pinning them in place. Rarity then fastened it on tight. Now Sun Butt couldn’t use her wings until her master said so.
Rarity looked over to the mannequin again and floated the tail wrap of it. The accessory looked like a long leather ribbon. She floated it over to the alicorn. Rarity grasped Sun Butt’s tail in her magic and pulled it straight. She wrapped the leather ribbon around the base of the tail. After a few moments she was done. After releasing her grip, Rarity watched as Sun But’s tail now stuck straight up at a slight angle.
With her tail raised, Rarity could see Sun Butt’s actual butt. She couldn’t help but chuckle to herself over that.
Next, Rarity levitated the large collar off the mannequin. It was basically a thicker vision of the collar Sun Butt was used to wearing, made of stiffer leather. Seeing it, Sun Butt knew to stand up as straight as she could. Rarity wrapped it around the neck, then fastened each of the buckles, making them good and tight. She didn’t make it too tight, so the alicorn could breath. But Sun Butt still found herself standing stiff.
And then came the final piece, the bridle. Rarity levitated it off the mannequin an floated it over. Sun Butt closed her eyes and held her head up. Rarity slipped the bridle onto her face, wrapping snuggly around her muzzle. Rarity fastened the straps on the back of the head, securing it.
Now the outfit was complete. Rarity took a step back. She, Discord, and Moon Butt all took a moment to admire Sun Butt in her new attire.
Sun Butt was now completely clad in full black leather tack. She was dressed in the same bindings as any beast of burden. Her fur was slicked and shiny, adding to the sleek look of the leather. Sun Butt looked like she had literally been dolled up by Rarity.

Sun Butt looked at herself in the mirrors around the stage. She liked how the tight leather felt all over. And she liked how she looked. She looked just how an animal should. And she only hoped her master liked it as well.
Discord walked around Sun Butt, viewing her from all angles. From all sides, she looked smooth and flawless. Discord was pleased with this look. The bindings were rather appropriate for the former-royal turned house-pet.

Discord looked at Rarity and said "This is perfect! As usual Rarity, you never fail to amaze. This outfit reflects Sun Butt perfectly."

Rarity replied "Your quite welcome. But now would also be a good time to share this outfit's extra features as well."

Discord grew curious and asked "What do you mean?"

Rarity said "Well you see, these clothes aren't just for looking fabulous. I built some special modification into them to make them practical as well. Here, let me show you."

Rarity turned toward Sun Butt, who was still admiring herself in the mirror.

Rarity said "Oh, Sun Butt! Could you please be a dear and walk back and forth across the room for us? Really strut your stuff!"

Sun Butt did as she was asked. She stepped down off the stage and started to walk cross the room, toward the wall opposite the stage. When she reached the wall, she turned around and walked back toward her owner. The heels didn't seem to limit her leg movement. But Sun Butt did have to walk in a way made that her rear legs shuffle one in front of the other. As she walked, her hips swayed back and forth, drawing attention to the actual sun on her butt. With every movement Rarity and Discord could hear the sound of her boots clopping on the floor. And the sound of her leather, squeaking on every part of her body. Sun Butt herself couldn't help but smile as she heard these sounds.
Sun Butt continued her walk cycle.

Rarity said "You see, I made the leather too be extra durable. Knowing how energetic your pets are, this was essential. What's more, despite how they look, the high-heel boots and stiff collar won't impede or limit their movement. Their more flexible than they look, so they can still run around. And finally, I made it so you can hook a leash or even a pair of reins to the bridle. I know you like to take the girls out for rides. Which is why the corset also doubles as a saddle. What do you think?"

Discord's mouth was wide open. He composed himself and replied "You built all that into them. Wonderful! I like it and I'm sure the girls do to. Don't you, Sun Butt?"

Sun Butt said "ARF! ARF! Yes, Master! Me like! Feel good!"

Rarity said "I'm glad to hear. Now it's Moon Buts turn!"

Hearing this, Moon Butt's ears perked, and she bleated "WOOF! YAY!"

And with that, Moon Butt eagerly trotted up onto the fitting stage. Discord ordered Sun Butt to sit next to him, and she complied. Rarity readied herself for her next masterpiece.
_____________________________________________________________________________________________
One hour later...

Discord came walking out of Rarity's store. He led Sun Butt, in her new outfit, out on a leash. He looked up at the sun, and could see it was now mid-morning. It was almost time for and Rarity to meet up with the others at the park. Looking at Sun Butt, he had very good idea.
Rarity came walking out behind Discord. She had Opalescence in her kitty-carrier on her back, and held a leash in her magical grip.

Discord said "It's almost time for us to be at the park. Are you ready to go Rarity?"

Rarity replied "Of course I am. And so is your darling, Moon Butt. Come along, Moon Butt!". And Rarity tugged the leash.

Moon Butt walked out behind Rarity, now sporting her own leather outfit. She now wore a purple and black variant of her sister's outfit. The only major difference was that Moon Butt's collar had a crescent moon on it, and Rarity had put neon-purple highlights in her mane.

Just like her sister, Moon Butt liked the feel of the skin-tight leather.
Discord was quite pleased with the results of Rarity's work. Both outfit were rather becoming for his pets. Now he knew they would be arriving in style. Especially with what he had planned.

Discord looked at Rarity and said "Rarity, I have an idea. Why don't we ride over to the park on the girls? It would only be right, since you made them. And I'm sure they both want to show off their new attire to the whole town."

Rarity replied "Why, that's a wonderful idea, Discord!"

With that, Discord snapped his paw. The leashes on Sun Butt and Moon Butt's collar were instantly turned into reins on their bridles. Discord gladly hovered onto Sun Butts back, and grabbed the reins in his paws. Riding the "once-great ruler of Equestria" as his personal transportation never got old for him.
Moon Butt knelt down on her knees for Rarity. As she knelt, her leather squeaked. Rarity levitated her kitty-carrier onto Moon Butt's back. She then climbed onto the alicorn herself and wrapped the reins around her hooves. Moon Butt then rose to her hooves.
With both Discord and Rarity mounted, they were ready to go.

Discord shouted "HI-HO, SUN BUTT! AWAY!"

He then slapped Sun Butt's flank. She reared up on her hind legs for a moment. And then she started to run. Moon Butt Followed suit.
Discord Rarity trotted toward Ponyville on Sun Butt and Moon Butt's back.
They rode with the park as their destination, knowing that the days fun, had only just begun...
