I've only found this part of it (Patreon)

Vinyl Scratch's horn glowed as she used her telekinesis to precisely wiggle the last rolling chest with her speakers into its place in the back of the SUV. Satisfied that none of her equipment would tip over or shift around during the drive to the club she swung down the back hatch and closed it. It was 3 in the afternoon and the concert wouldn't start until 9pm that evening, but she'd learned the hard way that waiting for the minute to load things always resulted in one leaving something behind. Now she could sit back and chill.

     The unicorn left garage and stepped back into the house proper. Upon entering the laundry room of the cottage Vinyl became aware of the heavy, muffled bass thump of music coming from upstairs. The mare smiled as she made her way up the stairs. Her and Octavia's tastes in music were radically different, but for her part Octavia had recently made an honest effort to learn and understand Vinyl's appreciation for House Music. In return Vinyl had begun to comprehend the attraction of classic orchestral music.

     What She heard coming from upstairs was not classical. The repetitive 4/4 beat and strong bass line was causing framed pictures hanging on the wall to buzz slightly as Vinyl reached the second floor. With a grin on her face the unicorn stepped into their bedroom and promptly stopped.

     Recently Octavia had started assisting Vinyl with her performances. Helping her set up before and tear down after the show. Also the earth pony was learning the fundamentals of DJing. An added benefit was that Octavia was very decorative and her presence had received appropriate applause from audience as she helped her lover with her performance. In particular she taken to dancing around the decks while Vinyl worked her musical magic.

    A contributing factor to the audience's appreciation was that Octavia, and Vinyl's, had a tendency to wear various visually interesting outfits and costumes. For this evening's performance the earth pony had expressed an interest in wearing the bunny suit she'd acquired a few years ago. Link  All she had to do was just figure out where she'd put it away. Well she'd found, um, well, uh part of it.

    The warm grey mare was wearing the black bunny ears, white linen collar with black bow tie and matching white cuffs. But that was all of the costume she was wearing and she was wearing nothing else. She was obviously rehearsing her dance moves in front of their full length mirror, For several seconds the earth pony kept dancing before she apparently noticed her partner. She paused the music and looked at the unicorn.

    "Oh hello darling. How's the preparations and loading of the car going.?"

    "Uh. The car is....stacked. Uh! I meant packed. Um, Octavia. Not complaining ya understand, bbbuuutttt where's the rest of yer costume?"

     Octavia slowly twirled around. All the while she kept her eyes locked on the mirror. As she continued to assess her presentation she spoke.

     "That's what I would like to know. I've only found this part of it. Have you seen it recently dear?" As she said she struck another pose in front of the mirror.

      "Um, no. No I have not. but I could help you find it if you wanted me to."

      Octavia struck another pose in front of the mirror. "Oh that would splendid dear! I really am at a loss to where the blasted thing could've wandered off too! Why don't you start with top shelves of our walk-in closet."

       "Uh okay." With that the unicorn wandered off to said closet.

      This is one of the drawings I started during last night's Picarto stream. It was my NSFW, bunny themed stream. As I was drawing the piece this was the little story that popped into my head.
