The Twilights new clothes

Twilight looked at herself in the mirror, the blush on her cheek seeming to be permanent by now as the unicorn next to her smiled and measured the base of her horn with a tape measure,

“There we go, Princess,” she said before she lowered hands, “I have the measurements I will need,” she said and slipped the tape measure into a pocket on her dress before brushing her pink mane back, “Now, have you chosen what style you will have for your regalia?”

Twilight shook her head, “No, Goldie. And you can call me Twilight,” she said and turned away from the mirror and did her best to ignore her state of dress.

Shimmering Gold smiled and nodded, “As you wish, Princ- Twilight. You know the mandatory parts?”

Twilight swallowed and nodded, “Y-yes. The horn filigree and the clithood ring.”

Golide nodded and leaned against the table, “Correct. Each with a half hoof width length chain ending with your symbol attached. But you need to pick another three items at least, but which you pick are up to you, Princess.”

“For example,” Celestia said and stepped up next to Twilight, sliding a hand around her waist to rest on her hip, “I have my clit and horn, but I also have my special shoes, my nipple rings and my necklace.”

Twilight looked up at her, “Special shoes? They are just not gold?”

Celestia shook her head and moved to sit on the table, crossing her long legs before reaching down to slip one shoe off her hoof before showing her. The inside has similar to a normal shoe with a hard outer edge for the hoof to rest on, but the inside seemed to be… silk strings that stood up straight and shifting back and forth.

Frowning, Twilight looked at it and then at Celestia, “...They tickle you?”

Celestia smiled and slipped it back on, “Yes, but not always. The less excited I am, the more they tickle me,” and then stuck her tongue out a bit, “A gift from my sister. When we had to pick, we picked one each for each other.”

“O-oh,” Twilight said and blushed, swallowing, “...What did you pick for her?”

Celestia laughed and winked, “You know her nipple shields?” shi asked and at Twilights nod she continued, “Enchanted to always draw the viewer's eye. At the time, she was envious that I had larger breasts. And when ponies look at them, they vibrate.”

Twilight blushed deeply, “...What else does she have?”

“Princess Luna has a buttplug and a tongue bar piercing,” Goldie said and returned with a list, taken advantage to get it while the alicorns were distracted, “ And Princess Cadance in addition to the mandatory ones wear a buttplug, a pair of chain connected nipple rings and a speech collar.”

Celestia nodded, “As you notice, each of us wear one enchanted piece. Cadances speech collar only allow her to talk if she is over a certain level of excitement.”

Twilight frowned, “...Why?”

“It’s part of the rules the councils made up when we were given the rule of Equestria,” Celestia said, “And we had to go along with it to keep the peace. The idea was that if we were sexually excited, it would be impossible for us to become tyrannical.”

“Oh.”

Celestia sighed softly, “...And they may have had a point. My sister stopped wearing hers as soon as we were in full command of Equestria. Less than a hundred years after that, she fell to the darkness. That’s why I kept to them and why we are still enforcing them.”

Swallowing, Twilight nodded.

“It’s not so bad, Princess,” Goldie said, “if you pick something you find that you don’t like, you can change out one chosen part every hundred years.”

Twilight nodded and took the list Goldie handed her, “...Can I think about it?” she asked and tried not to blush as she looked down at the selection.

“Of course,” Goldie said with a smile, “We have a few days until your coronation. They will take a day or two to craft depending on what you choose. So two or three days until I need your final choice.”

Nodding again, Twilight bit her lower lip as she studied the list. Everything the rest had, and more selections as well.

Celestia stood up and gave Twilight a hug, “Come, I’ll walk you back to your chambers. Until you are crowned…”

“I’m not allowed in public,” Twilight said softly and leaned against her.

“Actually,” Celestia said and stroked her mane, “...You’re actually not allowed to be alone. A princess or at least two guards have to be in the room with you at all times.”

Blushing, Twilight nodded and rested her head against Celestia's large soft breasts and the larger alicorn held her tighter, arms slipping around her and nosed at her ear,

“We will all help you through this, my student,” Celestis told her quietly, “And remember Cadance? Only a month until she started to feel comfortable, you will do fine.”

Twilight nodded and nuzzled against her cleavage.

“And she looks very nice.”

“Very sexy,” Twilight agreed before looking up at her, forcing a small smile, “I suppose I just have never thought about myself in those terms before.”

Celestia turned them around and then guided Twilight around to face the mirror before her hands slid up to stroke just beneath her breasts, “You best get used to it, Twilight,” she said softly, “Because you are beautiful and sexy. As part of choosing your regalia, I want you to spend a couple of hours studying yourself in the mirror.”

Blushing darkly, Twilight nodded.

“In addition,” Celestia said seriously and slid her hands up to cup her breasts softly, “Take my advice, my student. I know you plan to pick the easiest one, but that is a mistake. You will be wearing those for a long time. Choose what fits your personality and body, not what you think would be easier to wear.”

Swallowing, Twilight nodded and arched softly into Celestia's touch as she looked into the mirror.
