Twilight was lying facedown on a cushioned table, receiving a massage at the masterful hooves of Lotus. She was smiling contentedly as the spa's blue co-owner kneaded her shoulder blades, breathing slowly as she gazed at Rarity on the table next to her with half-closed eyes.
"I still can't believe that you had dinner with Princess Luna!" Rarity cried, squealing delightedly. "What I wouldn't give to be in your position!"
"But I thought you only had taste for Stallions," the pink Aloe said, lifting her hooves away from Rarity's back as she raised a brow in confusion.
"The Princesses are different," Rarity replied. "Their grace and beauty is at a level that transcends mere disinclination. If I'd known that either of them were interested in Mares I would've tried courting them years ago."
"Are you going to try for Celestia's hoof, then?" asked Twilight.
Rarity shook her head. "Oh, no, dear. I must be courteous; Celestia has neither shown an inclination to Mares nor availability for courtship. But I assure you, if Princess Celestia ever asks to take me I'll let her have me that very minute!"
Twilight blinked surprisedly. Never before did she imagine that she would hear Rarity so openly express such great physical desire for someone. "They'd really only have to ask?" she said. "They wouldn't even have to treat you to dinner first?"
Rarity gave a sultry smile to Twilight. "Darling, I am but their lowly subject. Who am I to refuse them?" It was clear what she truly meant; she might as well have said, "Why would I ever want to refuse them?"
The door to one of the baths opened, and Rainbow and Fluttershy came through it. Both were still shining with dampness and carried the sweet cherry scent of the water's perfume. Rainbow was grinning enormously, and Fluttershy looked a bit dazed but also very happy.
"How was your bath?" Rarity said to Fluttershy.
"It was lovely," Fluttershy replied softly. "I'm a bit tired, though..."
Rainbow smirked at Fluttershy. "Yeah," she said, almost growling.
"Interesting how you suddenly became interested in coming here when you became Fluttershy's girlfriend," Rarity observed knowingly.
"What can I say?" Rainbow said, shrugging. "The baths do it for me every time."
"It seems as though they... ahem, do it for Fluttershy, as well," Rarity replied.
Rainbow chuckled. "Yeah. So, what're you two talking about?"
"As it turns out," Twilight said, rolling her eyes, "it seems that Rarity is just as dirty as you two are. She was just telling me about how the Princesses could bed her with just a single word."
"Proudly," Rarity added, tossing her hair.
"I hear ya," Rainbow said. "Hay, they'd just have to give a look to me-"
Rainbow flinched, darted her eyes to a blank-expressioned Fluttershy, then nervously laughed and stammered, "T-that is, if I didn't have such a bombshell girlfriend already!" while putting her foreleg around Fluttershy's shoulders. Fluttershy frowned and groaned irritably.
Twilight sighed. "Does Rarity always talk about sex?" she asked Lotus.
"Yes," Lotus replied. "Though usually about Stallions, and not usually when you or her other friends are around."
"Thinking about courting a Princess will bring that side out in me," Rarity said, resting her chin on her hooves and smiling blissfully.

When Luna knocked on Twilight's door that evening, Twilight was napping curled up on her sofa in preparation to go out with the Princess that night. She yawned, stood up, stretched, then went to the door to answer it.
Luna was smiling as Twilight opened the door, and Twilight smiled back. "Good evening, Your Highness," Twilight said.
"Good evening," Luna said. "Are you ready to go?"
"Yep," Twilight said. She closed the door behind her and began walking with Luna.
It became dusk, and then nightfall as the two of them trotted away from the farm village deep into the great field that laid between Ponyville and Canterlot. The stars began to blink one by one into view, and Twilight found herself beginning to tremble. Luna responded by draping her wing around Twilight, to which the young Unicorn blushed and muttered, "Thanks."
Luna chuckled, then returned her eyes forward.
They said nothing as they walked, which suited both just fine; both were deeply introspective and reflective individuals, and were perfectly content to silently study the heavens together. It always gave Luna deep gratitude when someone was so enamored by her beautiful night; one of the biggest reasons she had taken such a great interest in Twilight was having heard from her sister of how she was one of those rare ponies who would spend hours just gazing up at the moon and stars.
Soon enough they found a rather tall hill, which they climbed and sat at the top of. They continued gazing at the stars. A few comets were falling occasionally, and Twilight thought she could detect the slow turning of the sky above her. Like Luna, she could spend an eternity just staring at the distant, vibrantly colored clouds of nebulae and the beautiful stars within them.
After a few hours of peaceful silence, Luna quietly said to Twilight, "How do you feel?"
After a few moments, Twilight said, "I'm very happy."
"That's wonderful to hear," Luna replied.
As time drew on, Twilight felt her eyes begin to flutter shut. She'd never felt more comfortable; the grass below her felt pleasant, and Luna's large, feathered wing was soft and quite warm. She nuzzled her head into Luna's chest, to which the Princess gently smiled.
"Twilight?" Luna said.
Twilight looked up at her, her eyes half-open. "Mm-hmm?" she said sleepily.
Luna reached her head forward and softly kissed Twilight. "Good night, sweet Lady Twilight," she said.
Twilight softly giggled, then rested her head on Luna's fore hooves. In moments she was asleep. Until dawn came Luna continued to gaze enchantedly at the beautiful filly's peaceful face as she slumbered through the night.
