"Luna, are you sure this is a good idea?" Twilight asked anxiously as she strapped on her helmet and knee pads, as well as wing guards.
"Positive. Besides, it's for science." Luna said, crouched in a predator's stance while she gripped the plastic sled firmly in her magic, waiting for Twilight to give her the go-ahead.
Twilight sighed. "I guess you're right." She was doing some research on propulsion magic, and after a few calculations, she had come to the conclusion that it was possible to fly across Canterlot without wings or chariots. Luna overheard this and gleefully suggested they test this theory. And since it was the middle of winter, they decided it was only logical to use a sled.
And that's why Twilight Sparkle was currently on the roof of Canterlot Castle above her study being strapped into a plastic sled and numerous pieces of "armor", including but not limited to a thick winter coat, wing guards, a helmet, goggles, and a few pillows. She now resembled a stuffed toy.
With a final snap, Luna fused the ends of the thick strip of fabric they were using as a seatbelt to each side of the sled. "Are you ready?"
Twilight lit her horn in preparation for the spell and nodded. "Launch in three, two, one..."
"FOR SCIENCE!" The second Luna pushed Twilight, she detonated her spell, and she went rocketing off the castle roof and into an arc across the sky. To ponies safely on the ground, it would look like a screaming purple pony-sized marshmallow was flying through the air while Princess Luna flew under it.
Twilight was having the ride of her life. She was flying through the air without her wings or a chariot or any sort of aide. It was almost like teleporting, only much more frightening and with a much higher chance of failure. And in the midst of her terror, she noticed with alarm she was falling. "Luna!"
And then she wasn't falling anymore. She was safely in the grip of the navy blue alicorn that she loved, and she was alive and safe and she was still buckled to the sled. She un-fused the fabric strip and planted a kiss on Luna's lips just so she could know the sensation of it and reassure herself that she was indeed alive.
She snuggled a little deeper into Luna's embrace as they flew back into her study window. Once they were safely inside the heated castle, Twilight took off all her winter gear and safety measures. Then she immediately rushed to her desk, scribbling notes.
"Twilight..." Luna started, but Twilight ignored her.
"I need to reconfigure these calculations, and this spell matrix here most likely, figure out what went wrong..."
"Twilight. Relax for a little while, please. You worry me." Luna gave Twilight a hug.
Twilight gave her a cheery smile. "Isn't that why you love me?"
"One of the reasons why, yes. Now, come here and snuggle with me before you work yourself anymore." Luna picked Twilight up despite her half-hearted protests, and placed her on the cot Twilight had in her study to make sure she slept at least a little, and gently stroked her mane until she fell asleep.
