In the clean white front room of the boutique, two unicorns played.
“Oh, Rarity, I still can’t believe how good you are at that!”
White lips curled in a smile, and she did it again, eliciting a yelp, then a moan, from the lavender unicorn.
Twilight pushed her away. “No, no—oh Celestia—no, stop, cease, desist.” As the disappointed white muzzle lifted away, Twilight rolled and squirmed until she was facing Rarity. Purple eyes met blue with a practiced (secretly, in the mirror) hungry look. “Now it’s my turn.”
The hum of magic filled the air, followed an instant later by an unladylike grunt, shading into a moan. Twilight grinned.
Rarity spoke around the hank of her own mane clenched in her teeth. “Oh, Twilight, darling, it’s—Uh! Luna preserve me—marvelous! Do the thing with your horn again, and can you do the other thing too?”
Twilight wriggled closer and wrinkled her nose as she concentrated. The hum of magic intensified, and Rarity bit down on the hair in response. A long moment later, she found her breath and gasped, “Twilight! It’s— now, the time, with— with the rutabagas and the glitter!”
Twilight paused to cock her head at Rarity. “Are you sure? Last time—”
Rarity flailed her arms toward the hat rack and the tandem bicycle. “To Tartarus with last time!” She flipped over and thrust her head out of the turtle shell, fixing Twilight with a desperate glare. “It’s time! I need it! Get the rutabagas!”
Twilight saw that Rarity’s mood ring and mood go-go boots had turned from pink to tangerine, and she looked to the side and exchanged nods with the hedgehogs dressed as the cast of The Marechant of Venice. She reached out with her magic and lifted the rutabagas, glitter, and bucket of lead-free paint, a thrill running through her at hearing Rarity’s breath quicken in anticipation.
The front door of the boutique slammed open, and bright midday sunlight streamed in and illuminated the entire tableau. Applejack’s voice drawled through the room as she backed in, dragging a heavy bag in her teeth. “Heya, Rarity, I got those apples and apple accessories you wanted. I’m powerful curious as to what you need ‘em for—” Applejack turned around at last.
Twilight shut off her levitation spell, causing sixteen thuds, five squeaks, and two splats. A tight grin pasted itself onto her face. “Hi! Applejack! Lovely day, isn’t it? Listen, about all this—”
Applejack interrupted, almost a shout. “Eeeeenope.” She spun on her heel and walked out, closing the door firmly behind her.
Twilight let her hoof drop. “Uh . . .” She looked helplessly at Rarity.
The white unicorn looked back at her and raised an eyebrow. “Well, back to the rutabagas?”
Haha, all the little unexplained (and unexplainable?) details are great. It leaves the reader wondering “just what are they doing with all this stuff?” but at the same time “Do I REALLY want to know?” And using their voices to convey that SOMETHING was going on without actually describing it was a clever way of getting around the “no clop” rule. We have rules but it’s good to be creative with them.
