Twilight had been standing there for over an hour now as Rarity got inside her personal space to take measurements and test out colors against her coat color to see what would work for her latest designs. If Twilight did not know any better she would have thought Rarity took at least one chance to cop a feel of her growing bust line as she measured it. Really, the wings were a great enhancement from the ascension however the increase in height and the new muscle definition that came with the earth pony magic left her with a great problem. It had set Rarity off in a habit of wanting to dress Twilight up in slightly more masculine cut clothes. Twilight was rather opposed to this for various reasons not least of which were that she felt far more comfortable in skirts than pants.

Rarity for her part had just finished with her selection for a top for her friend and began to ready the tape measure to check which adjustments were needed to Twilight’s old readings. Really she doubted Twilight actually knew how often her measurements had been changing since her ascension though it was only ever by a few centimeters here or there at a time but that adds up over the course of a year. Her eyes gleamed as she continued to take measurements preparing to slip a surprise on Twilight. While the scholar was distracted, likely by reciting pi inside her head again like the last three times she had her model, Rarity tried to measure her inseam.

“Hold still darling. I’m just making sure I have everything I need for your legs. It wouldn’t do to leave too much exposed after all.” Rarity told her friend even as her tape began to snake up the alicorn’s leg.

‘4461284… shoot I lost my place. Back to the start. 3.14159…’ Suddenly Twilight’s count got derailed again by feeling something touching somewhere it really shouldn’t have been. The mage princess’s glowing red face gazed upon her friend. “Rarity, wha… what are you doing?”

“My job, Twilight. I needed to measure your leg to make sure I will make the proper cuts later. I just got done telling you that.”

“Oh, sorry Rarity.” Twilight answered still pink of cheeks. “Make sure I’m actually paying attention next time first, please. That was unexpected.” Twilight did her best to not react to the fact that the tape measure was still touching her. It really wasn’t Rarity’s fault though. The poor unicorn had no idea of Twilight’s condition or how her apotheosis had affected it so she could not be blamed.

As Rarity recorded her findings and set to work Twilight stood there lost in thought as was her habit. ‘It was always hard to keep my secret hidden but it has become really hard to keep this secret recently especially. Why did everything have to get bigger?’ Speaking of harder to hide Rarity bent over to fetch some thread and Twilight had to exert a bit more magic than usual to keep up her illusion. ‘If something isn’t done soon I’m going to wind up giving in and becoming the princess of friendship with benefits.’

Rarity pretended not to notice Twilight’s gaze homing in on her behind as she bent over at just the right angle to get the thread. She allowed herself a smirk knowing she could even rile up a rather conservative royal with so little effort. ‘Works with every customer and keeps them distracted. Plus it’s kind of funny to see their expressions.’

Twilight rapidly descended into her mind once more to keep herself under control. As her eyes trailed she failed to see Rarity take this chance to begin sewing pants rather than the skirt she was expecting.

“Spike, emergency. Get me some scissors now.” Twilight materialized in the middle of the library without a top on but the tightest pair of pants Spike had ever seen. He rushed into the room and forsook the scissors to employ his claws as he knew what the problem was. A quick swipe and the front of the pants were open and Twilight sighed.

“What the heck Twilight?” Spike asked as he turned his head away to avoid noticing his sister swinging in the breeze. He might have been in the know but he always was freaked out a bit when he would accidentally catch a glimpse during the usual bathroom mix ups that come with living with another being.

Twilight was too busy sighing in relief to care about anything else at the moment. “Spike, take down a note to never let Rarity ever make me pants again. Cut to fit doesn’t work when you’ve got bits that aren’t seen involved.”

As Spike groaned and rubbed his face with a claw the front door opened allowing Rarity to charge in.

“Twilight, what was that abou…. ?!”

“Rarity, uhm... ahahah, this isn’t what it looks like?” Spike began to try and explain to her what she had walked in on.

Twilight uncaring of the situation just looked Rarity straight on. “What can I say, I needed relief.”
