Sunset woke up from her slumber, her hair was a bit messy and her body ached a little from the previous night. She and the boys had been teaching her slave, the former princess Cadance, a lesson in re-learning her place from the events that happened. As she walked outside the room, Cadance’s muffled cries and moans could be heard from the basement floor. She peered inside and saw that Ultima, former second Lieutenant of the guard, was working away at Cadance’s pussy while Flash Sentry laid exhausted, his load already spent inside her mouth. She closed the door with a grin in her face and allowed them to continue, wondering which was the worst punishment she had to suffer: being fucked senselessly or not being able to climax. As she began preparing herself a hearty meal of bread, cheese and some red wine, her ears perked up at the sounds of footsteps coming down the stairs.

“M-mistress Shimmer… Good morning.” Said Fluttershy, whom was having trouble holding herself upright and had to use the railing as support. Her butt was still red and her eyes were a bit groggy from lack of proper sleep. She went over to her mistress, got on her hands and knees then kissed her feet.

Sunset’s smile grew as she sipped her cup of wine as she watched the yellow Pegasus worship her, knowing that defiling her would mean a punishment equal to what she received last night or worse. “Greetings pet,” she replied as her hand ruffled Fluttershy’s hair, “I hope you got along with your new companion last night.”

Fluttershy almost immediately placed her hands on her butt, to which Sunset laughed at. With a blush on her face she removed her hands, got up and gave an odd smile of approval. “Y-yes… Pinkie and I had… lots of fun together last night.” She replied as she looked at the ground, the memories of what had happened to her still fresh in her mind.

Sunset moved her hand underneath Fluttershy’s chin, tilted up her head and gave her a sweet kiss in the lips which helped calm her down. “I’ll let this lie slide,” she said with a cold tone to her voice, “only because you’re cute when you’re embarrassed.” She continued to play with the mare’s tongue until they both suddenly sprang up in surprise as they heard a knock on the door. Only a few people in this town knew what this once abandoned house was housing Princess Cadance so this had to be addressed to her. With the princess currently… occupied, she leaned into Fluttershy’s ears and whispered. “See whom it is, tell them that the Princess is not to be disturbed and get them to leave… I will be watching and listening closely.” Her voice made Fluttershy shiver with both fear and excitement.

As soon as Sunset was away from view of the door, she marched up, Fluttershy did her best to straighten her hair and adjust the pajamas she had put on after waking up in the nude next to Pinkie Pie. Carefully opening the door, she poked out her head and saw a Crystal Pony with a package under her hand. Her whole body, and clothing, sparkled under the morning sun, she wore an emblem that represented the mail service and she had a very peculiar set of shoes on that had wings which resembled that of a Pegasus. “Umm… hello, how can I help you?” Fluttershy asked, wondering just how she was going to lie her way out of this.

With a quick bow she revealed a small pin underneath her collared shirt, which looked identical to that of Sunset’s cutie mark. “I bring a package to her new highness, let her know that we have found what she was searching for.” Her tone was low enough for Fluttershy to hear but it seemed that Sunset had heard anyways for her magic swung the door open wide enough to allow the guest through.

“Come, Quicksilver, show it to me.” Sunset had reappeared inside the kitchen, swishing her cup of wine as she bared a smirk.

Before Fluttershy even realized it, the mail mare had ran inside faster than anypony she had ever seen run. Stopping right in front of Sunset, she was already down on one knee and presented a box to her. “As you instructed, we searched the catacombs of the old castle for any artifact that might have belonged to King Sombra. Though most of the old texts lead to dead ends or missing treasure, we were able to find one.” She opened the box and revealed an old, broken black mask that would have fit perfectly in an opera.

Sunset slowly picked it up and smiled with glee. “The Changeling mask.” She had read about this artifact during her short stay in the Crystal Empire, knowing that she would need every toy the old king once used to get an upper hand. “Crafted by Sombra himself, he embedded it with Changeling magic so that the wearer could turn into whomever the wearer desired. It’s a shame it only has a limited time period, otherwise he might have escaped the hands of Luna and Celestia.” Looking down at the mail mare, she asked her whom had been responsible for finding it.

“Umm… I believe it was Cadance’s old hand maiden, Sureibu.” She replied

“Sureibu… Ah yes, I remember her.” She thought back to the day after her conquer of the Crystal Empire where she had used the special services of the blue Pegasus maid for her own pleasure. Though unexperienced with pleasuring a woman, she showed a lot of potential of being a perfect pet. “You may return to the Crystal Empire, tell them to continue the search,” she paused for a moment then added, “also, tell Sureibu to expect a reward when I see her again.”

Quicksilver blushed, wondering just what she had in store for the lucky mare. “Understood mistress.” She gave a quick kiss on Sunset’s feet, just like Fluttershy had earlier, and dashed out the door, leaving a trail of dust in her wake.

Sunset looked at the mask, inspecting it closely, and then finally decided to put it on. She had read on how the device was supposed to work, all she had to do was picture the pony she wanted to transform into. Her body began to get a little shorter, her horn shrunk until it disappeared into the forehead and wings began sprouting out of her back. Her body, which was as orange as the sun, changed to a cooler blue tone. Finally her golden locks began turning red, matching the rest of her hair, and her cutie mark was beginning to be covered by a new one that looked like a cherry blossom. Sunset Shimmer was no more, before Fluttershy now stood the former hand maiden of the Princess: Sureibu. The mask also transformed, it was now a cherry blossom hair clip adorned on her head. After examining her body and looking in a mirror she smiled so hard that it hurt her cheeks. “Fetch me some clothing,” she ordered Fluttershy with a voice that was not her own, “I think it’s time I get some fresh air in this town.”

After acquiring a simple yellow dress, which was a bit tight for her new body, both Sunset Shimmer and Fluttershy left the house and headed out to Ponyville. The markets were beginning to set up for their daily sales, children ran to school before the bell rung and everypony seemed happy and eager to get the Summer Sun Celebration started. It seemed though that the mask had a bit of a minor malfunction that she hadn’t planned on: Though she had wings, they did not give her flight and even with her missing horn she could still feel the surge of magic in her. But this mattered not, she was still happy to walk around everyone without the slightest hint to her true identity. As they continued along she noticed that a lot of stallions were looking her way, it seemed as though they knew the same thing she had: Sureibu’s exotic looks were something to behold.

“Here you go mistress Sunset.” Said Fluttershy as she held up a small cup of vanilla ice cream, her face blushed in hopes of pleasing her.

“I told you to not call me that!” She snarled back in a low voice that only the two could hear, taking the cup in the process and eating the contents. “You are to address me as Sureibu, don’t forget it again.” She continued to walk forward, followed by Fluttershy whom had a very sad look on her face, and viewed her surroundings. “Take me to the town hall, I must survey this town’s…”

“Fluttershy, darling, how have you been?” Came a voice from behind the two, the beautiful Rarity marched up to the duo as she carried several bags of fabric materials with the aid of her magic. “I went to visit you yesterday but you weren’t home, I must say, you had me worried there for a moment.”

Fluttershy had a nervous look on her face, she looked at the disguised Sunset and hoped to make up for her earlier blunder. “I was spending the day with my pen pal here, her name’s Sureibu. She came from Trotokyo to see the Summer Sun Celebration this year and I was busy showing her around.”

Taking the hint, Sunset bowed to Rarity in a manner only seen in the eastern lands and greeted her. “It is nice to meet you Miss Rarity, I am honored to visit your town.” She did her best to fake an accent, which, to her surprise, sounded very real.

“Oh my, a foreign visitor. You must come to my shop and tell me all about the latest fashion designs from Trotokyo.” She took a quick look at the tight yellow dress that Sunset was wearing and gave her a weak smile. “Perhaps I can also help you with your… problem here.” Pointing at the dress.

Sunset, or rather Sureibu, bowed herself once more. “I thank you for your offer, Miss Rarity, I will accept.” This'll be her chance to get this lovely gem under her foot and it'll also be a chance to see just how much Fluttershy had learned in her stay.
