Sweetie Belle thankfully woke up before Rarity, giving her time to remove the used dildo from the floor and clean it up before her sister saw it. Once she was done washing it off, Sweetie almost put it back in her sock and underwear drawer, but after deciding that she wanted this week to go perfectly Sweetie decided to bring it with her after all. Making sure to hide it as deep in her suitcase as possible, she finished packing just as Rarity came knocking on her door to make sure she was ready to leave soon.

As expected, Sweetie Belle and Rarity found Spike waiting outside, eager to help carry their luggage to the train station. Sweetie Belle couldn't help but giggle as the young dragon tried to lift all the bags at once to show off his matured muscular body, just as he had tried many years ago when she was still in elementary school. 'Almost ten years later and he's still obsessed with her.' she thought.

Seeing that Spike would have enough trouble moving even half of Rarity's luggage, Sweetie gladly pulled her lone suitcase herself, being a much lighter packer than her sibling. She and Rarity made it to the train station in the amount of time expected, but surprisingly Spike was only a few minutes behind them, somehow managing to carry Rarity's absurd amount of belongings in one trip. He was sweating profusely and gasping for air when he set down the last large trunk but quickly tried to appear cool and collected when Rarity walked up to him to thank him. As Sweetie Belle predicted Rarity walked up to Spike and hugged him tightly, making sure to press her voluptuous chest into his body before she then kissed him directly on his lips. Sweetie Belle smirked as she recalled Spike's eighteenth birthday a few years ago; after the main party had ended, Rarity had pulled Spike aside to give him her 'special gift', and once he came staggering out almost thirty minutes later Sweetie knew all too well what her sister had done for him. Seeing her walk out wiping her mouth moments later just confirmed what she knew...

Once the train had departed Ponyville, Sweetie leaned back in her seat to enjoy the train ride to Manehattan, but she should have known the trip would have been anything but. Almost immediately Rarity pulled out her notebook and tape measure before descending on her younger sister, taking a torrent of measurements all over her body before quickly jotting down her findings in her book, muttering about potential alterations she may have to make before the fashion show.

"Rarity, calm down! I haven't gained or lost any weight since last time!" she said as Rarity yanked her arm up to measure her sleeve length.

However, Sweetie Belle's protests fell on deaf ears, Rarity wanting everything to be absolutely perfect. Only when Rarity had finished her third round of measurements to triple-check her designs did Sweetie finally manage to slip away and wander back to the caboose. With the conductor busy patrolling the train cars she had the rear car to herself, allowing her to enjoy the peace and calm of the train ride to the largest city in Equestria. Thankfully Rarity didn't come looking for her at all during the trip, though Sweetie did catch a glimpse of Diamond Tiara and her father Filthy Rich as she made her way back to her seat when Manehattan came into view.

As Sweetie Belle and Rarity disembarked the train, they saw their host Prim Hemline waiting for them along with a few strong, burly stagehands to help unload Rarity's luggage and help transport it to the venue. Insisting that she must oversee the unloading and transportation of her dozens of items, Rarity stayed behind to supervise the careful handling of her hand-crafted dresses while Sweetie followed Prim over to the taxi stand.

Quickly whisked away in the cab, Sweetie found herself being shown to the dressing room of the Fashion Week venue in what seemed like the blink of an eye. Prim quickly showed Sweetie her seat and dressing area before rushing off to oversee the final lighting arrangements out on stage, leaving a nervous Sweetie Belle alone and intimidated among the other models present.

Sweetie couldn't help but ogle the other mares present, some of them grooming themselves meticulously while others talked and showed off their bodies. Almost all of them wore only their underwear but a few of them were walking around topless, and to Sweetie's embarrassment two or three of them were completely naked! Compared to everyone else present, Sweetie was definitely overdressed...

"You must be the new model Fancy Pants referred." a voice said behind Sweetie. Turning around, Sweetie's mouth fell open as she found herself face to face with one of Equestria's most famous model; Fleur Dis Lee.

Sweetie's star-struck state soon gave way to her blushing heavily as she realized that the gorgeous unicorn was stark naked. Despite her attempts to avert her eyes, Sweetie couldn't help but look over Fleur's body with envy; the experienced model had the perfect figure, one that even the princesses envied to have. Her slim waist went perfectly with her curvy hips and tight, round ass, and her c-cup chest remained perky and firm. She was the envy of every mare and the wet dream of every stallion, and it was no wonder the issue of PlayPony that featured her was the best selling issue of all time. It was also very clear that Fleur was used to having everyone staring at her body as she continued to speak despite Sweetie Belle almost drooling over her naked form.

"You're the new model, Sweetie Belle, right?" Fleur Dis Lee asked again, she herself eyeing over the younger mare in front of her. "Your sister is that new hot dress designer, Rarity, right?"

"Y-yeah." Sweetie managed to blurt out while nodding. "I'm, uh... this is my first model... thingie..."

Fleur giggled at Sweetie Belle's obvious nervousness, having seen it countless times before. "Well, you've made quite the impression on Fancy Pants at that small modelling 'thingie' you did a few months ago. I've never heard of any model being thrown right into Fashion Week for her first show. It took me almost six years before I was ready for this level of work."

"Yeah... I-I guess so." Sweetie said nervously. "I, uh... I hope I'm ready for this."

Fleur offered a reassuring smile and placed a hand on Sweetie's shoulder. "You'll do fine. Fancy Pants wouldn't have suggested that you come here if he didn't think you could do this." she said.

"Alright, ladies, time to start rehearsal!" one of the managers called out, beckoning for everyone to follow her. All the models filed out of the dressing room and through a set of curtains but before Sweetie could follow everyone else she felt Fleur stopping her.

"You're not going to change first?" Fleur asked quizzically.

Sweetie's face fell to one of complete confusion. "Huh? Change into what? Rarity hasn't brought my wardrobe over yet."

"Oh, we don't wear our outfits for rehearsal." Fleur explained. "This is to practice our walks and poses. We have to make sure every little detail is perfect, so you're supposed to strip down."

"Oh yeah... yeah, I knew that." Sweetie quickly said, not wanting to appear completely oblivious to what she assumed was common knowledge. The sting of Diamond Tiara and Silver Spoon being right about... THAT... still stung, and Sweetie kicked herself for not knowing this fact either. Not wanting to delay herself any more, Sweetie quickly stripped herself down to her underwear before following Fleur Dis Lee past the manager and through the curtain.

And right out to the main stage.

Despite almost every seat in the main room being vacant, Sweetie couldn't help but once again blush deeply from embarrassment. The thought of being this naked in a somewhat public place was almost too much for Sweetie to handle, though the thought of her wearing a just-as-skimpy bikini at the beach every summer ironically didn't bother her. Still, she couldn't believe that some of the other models were topless. Or naked.

"Okay, ladies, line up! We're running a little behind schedule, so let's get started! Let's start with your basic walks. Okay, and... begin!"

Sweetie quickly got into line in front of Fleur and the lights dimmed slightly, the only lights remaining on full power being the spotlights concentrating on the runway. Music began softly playing, just loud enough for the beat to be of use for each mare to use to time their rhythm, and without any more hesitation the first model in line began her strut. There were only five audience members present; all of them staff for the show; Photo Finish, Prim Hemline, Sapphire Shores, and two other managers Sweetie didn't know. All of them carefully watched each mare make her way down the catwalk, offering criticism to perfect their walking as it was each model's responsibility to show off each outfit completely flawlessly.

"A little faster, you're slightly off tempo."

"You're strides must be slightly longer."

"Broaden your body, straighten your back more."

"Yes, perfect, just like that!"

Sweetie gulped as she became more nervous as her turn came closer and closer. The stagehand commanding each model to go soon counted down the seconds for Sweetie to start walking in a hushed tone, just loud enough for Sweetie to hear.

"Three, two, one, go." the stagehand hissed.

Throwing herself forward, Sweetie walked out onto the catwalk and into the spotlight, trying her best to walk to the music and retain the correct posture. However, to her horror she heard Prim almost immediately call out her criticism.

"No, no, stop! It's all wrong!"

Sweetie Belle froze as she tried to figure out what she had done wrong. "Wha- huh?" she said in confusion.

Being the closest to her, Photo Finish got up out of her seat and approached Sweetie Belle. "Ze tail, zis is not correct. It must be higher!" she said, lifting Sweetie Belle's tail up to the appropriate height before letting it fall back down.

"Like... this?" Sweetie said as she struggled to lift her tail to the level Photo Finish had indicated. However, she only managed to get it about three-quarters of the way up before she gave up and let her tail fall back down once more.

Looking quizzically at Sweetie, Photo Finish once again grabbed Sweetie's tail and lifted it up, but this time held it up as she leaned forward and stared closely at Sweetie's rear. "You do not has ze plug, no?" she asked slightly too loud for comfort.

Sweetie had no choice but to shake her head no. "N-no, I don't have my suitcase yet." she explained.

Prim shook her head. "This is no good, we must ensure everything is perfect now before dress rehearsal and then the main event." she said sternly.

Sweetie felt her heart drop. She knew that her belongings would have been taken up to her and Rarity's room so her older sister could ensure everything was perfect. However, before Sweetie could worry any further Fleur walked up and placed a reassuring arm around Sweetie's shoulder. "It's okay, I have an extra one she can use. We'll be right back." she said before guiding Sweetie away.

To Sweetie Belle's amazement, there was no snickering or laughter or mocking. Instead, all the models returned to the task at hand as Fleur led Sweetie Belle back to the dressing area. It was easy to see that Sweetie was slightly humiliated over being called out over her tail, but Fleur understood that remembering to bring the appropriate 'tools' to rehearsal was easily overlooked or too embarrassing. She certainly felt uncomfortable doing the same her first fashion show.

"I'm sorry, I didn't think..." Sweetie began to apologize but Fleur hushed her immediately.

"It's okay, you're not the first mare to forget it." Fleur Dis Lee said calmly. "There's nothing to be embarrassed about either. We all use one so there's no need to feel weird about it."

"Yeah, okay." Sweetie said, finally starting to feel calmer about everything. She followed Fleur over to her dressing area, the more experienced mare model bringing out a wooden box and placing it on the counter in front of her make up mirror.

"I always bring a few extras just in case there's a last minute wardrobe change." Fleur explained, opening the box for Sweetie. The younger mare looked inside and felt a cold shiver shoot down her spine as she saw five strangely shaped objects with a different colored jewel embedded in each one. Each one was shaped identically like the other and there was an empty spot where a sixth one presumably went, which Fleur had most likely taken to use herself. However, no matter how long Sweetie stared at the objects she had no idea what they were or how to use them.

"Uh... what are they?" Sweetie Belle finally asked, completely stumped.

"They're butt plugs, silly." Fleur said, unable to help but smile as she correctly guessed that Sweetie Belle was very new to professional modelling.

"Oh, yeah, right." Sweetie quickly said, trying to save herself from further embarrassment. "I just, you know, they look different from the ones I've used before."

"Right, I see." Fleur said with a wink. "Anyway, go ahead and pick whichever one you want."

Looking over the choices she had, Sweetie noted that all the plugs were the same size and only differed by what jewel they had embedded in them. She eventually chose the butt plug that had a clear diamond in it, choosing the neutral color as it would hopefully go with anything Rarity had designed. However, as she held it Sweetie felt a weird knot forming in her stomach; her dildo hurt slightly when she had put it inside of her ass, and this butt plug was easily over twice as thick at its widest point. Fear dominated Sweetie's mind; this was way too big for her to fit inside of her ass, but if all the other models could use something like this, surely she should be able to as well. There was only one problem...

...how did this thing work?
