Stars: 00000001
It was a beautiful night.
The stars were arranged in intricate patterns never seen in living memory, the sparse galaxies cavorting in an eternal dance across the otherwise pitch-dark sky.
The creator of this wonder, however, had not been struck by a flight of inspiration on this particular night. It was a design she'd used many times through the centuries, though it was only the first time she'd used it since her recent return to Equestria.
On this night, after bringing up the moon, she sat in the palace library, brooding. This was to be expected, of course - her transformation from Nightmare Moon had shaved a few (thousand) years from her physical age, bringing her right into the angsty teenager phase of her development.
The servants had long since figured out that Luna preferred her own company during the night.
Luna, as always, was sitting at her window, gazing at the baby-blue sky, lost in her own thoughts. A servant nervously approached.
"Can I get you anything, Your Majesty?"
"No."
"Anything to drink... eat... somepony to talk to?"
"Continue to pester me and I'll vaporize you. You know I can kill you with my mind."
Thoroughly spooked by what would normally be an idle threat, the servant fled back to her quarters, where she calmed herself down with a glass of berry punch.
The truth of the matter was, however, that Luna was lonely. Celestia was always busy with her royal duties - holding court each day, and spending what free time she had- no, she never had free time. The relentless grind of Equestria's bureaucracy prevented any of that occurring.
I'll just go and talk to her. She's my big sister, she'll make time for me... won't she?
Luna found her way through the dark passages of Canterlot Castle, studiously avoiding the servants who populated the castle at all hours of the night. After searching through the throne room, the atrium, and the garden, she finally found Celestia at a table in the palace kitchen, surrounded by mountains of paperwork and munching on a platter of toast.
As Luna approached, she heard Celestia faintly mumbling to herself.
"My wings are so pretty... I'm a princess... are you a princess too...?"
She cleared her throat.
"Excuse me."
Celestia glanced up briefly. "Yes, I'll have more toast. Thank you."
Nonplussed, Luna walked over to the counter and picked up a loaf of bread. She then telekinetically lifted it, sliced it with a dull butter knife, and shot a fire spell at it. To her credit, Celestia didn't even notice, even when Luna shrieked and dunked her smoking horn in a bucket of water.
With that drama done and dusted, as the farmponies of Appaloosa would say, Luna carried the toast and a stick of butter over to Celestia. As she approached the table, a stray paper from the table somehow got caught under her hoof, and suddenly, with no warning whatsoever, the Moon Goddess flew headfirst into one of the towering piles of paper.
As the snowstorm of papers settled, she found herself lying on her back in front of her sister, covered in toast and with a thick sheen of butter coating every exposed surface.
Celestia, for once, was caught by surprise. Luna had to suppress a giggle, despite her awkward position.
She blinked as if awakening from a deep sleep.
"Luna...?"
Deadpan. "Celestia."
The older sister, now fully alert, glared at the filly lying before her eyes. She sighed heavily and stood up.
The Moon Goddess was slightly worried now.
Celestia lowered her head with a grim expression on her face.
Oh dear I don't want to go to the moon not the moon oh please not the moon heyyy what-
Luna broke off her internal monologue as her sister started tenderly licking the butter off of her flanks. The texture of her tongue evoked memories from before... of both colts and mares... hey, even the Princesses got lonely (and frisky) sometimes-
"Celly- what the hay are you doing?"
The elder sister raised her head and stared into Luna's eyes, as if silently challenging her sister to protest.
"I didn't say stop."
It was warm. Warm and fuzzy. As Luna slowly floated her way back into full consciousness, she became aware of a dead weight laying on her chest.
She decided to open her eyes and assess the situation.
The room in which she laid was decorated with motifs of the heavens on the walls, with sunlight streaming through a single large window. To her left was an ornately carved door, big enough for her or her sister to fit through easily.
With her bearings firmly set, she decided to look at what was lying on her. What she saw, however, was not what she expected - she'd been thinking a heavy pillow, or perhaps a chunk of masonry from the ceiling.
I- what happened last night? There has to be some rational explanation for this... for why I'm lying in Celestia's bed with her half on top of me... right?
At that moment, the Sun Goddess stretched luxuriously, apparently savouring the texture of Luna's mane.
"Celly."
With that, her eyes snapped open. Like Luna, she took a few seconds to figure out where she was.
"Luna, why are you lying in my bed, and why am I lying on you, and, most importantly, why does it feel so right?"
"I... I don't know."
