One Morning
“Ugh...” the gray earth pony groaned when she was awaken by one bad headache. “Wha-what happened...” she muttered. It took her few moments before something started to dawn to her mind. “Right...” she muttered. “Vinyl got me to one of her parties again...” she groaned annoyedly.
Suddenly there was movement behind her and slender hooves wrapped themselves around her. “Oh no!” she thought now distressed. “Not again!” she was now being pulled against the figure behind her.
“And this should be the number one reason why I shouldn't always attend Vinyl's Late Night Parties...” Octavia tried to struggle against her captor without little success. She then suddenly took another notice, that the one, undoubtedly mare, who had her in her hooves was rather slender for a regular pony.
“I don't know if this is more frightening than waking up in Vinyl's hooves...” while this has happened only few times, it was still always annoying as ever. While nothing never really happened between them, except some kissing maybe, Vinyl always has to make it sound completely different and embarrass her.
But her thoughts were soon drawn away from her situation, and instead stared at the room she was in at the moment.
It was different. Completely different from Vinyl's house which usually isn't this clean. Maybe she was at one of Canterlot's Hotels or Motels. But then she noticed that this wasn't exactly your regular Canterlot Hotel or Motel room. Everything looked way too expensive and with lack of better word, delicate. In fact, they were too delicate. And fancy
And now that her brain was working even better, and her headache also suddenly forgotten, she noticed how dark this room was. Not in dark way that she couldn't see anything, but dark blue colored. And a certain painting before her got her attention.
“Somepony really loves night skies...” Octavia thought to herself, while looking around the room. “Wait what!?” she hurriedly turned back to the paintings. And then started scanning the room again.
She then felt the warm blanket moving around her body as it's feathers tickled her a bit. “Wait. Feathers!?”
Octavia then heard as her “bedmate” moaned loudly from being taken from the land of the dreams. While she couldn't fully turn and take a look, she already had really, really good idea of who she was sharing the bed with. And she already knew the reason behind it too. “Vinyl... I'm going to murder you once I get out of this situation!” Octavia screamed in her mind.
Slowly, things started to come back. The party Vinyl had thrown, the sudden appearance of Canterlot Royalty. Princess Celestia telling to keep the party going. After that, things were still quite blurry, but she remembered, Princess Luna and Vinyl with their drinks. Her leaving Octavia with the Night Princess. Them talking and after that, things got really fuzzy.
“Oh my goodness...” the Night Princess muttered as she was waking up. “This is it then...” Octavia dreaded.
The wings soon left her side, much to her disappointment, she rather liked them being on her body, as Princess Luna stretched them, but then stopped when realizing that there was something, or someone was wrapped around her hooves.
She fought for a short moment the light that was pushing through her curtains, slowly the Princess's eyes adjusted to the harsh light of the sun and was now looking at a certain grey frightened earth pony.
“Oh my...” Luna said while staring at Octavia.
And Octavia was staring back.
“This... this is rather...” Luna started. But couldn't finish her sentence when Octavia suddenly bolted away from her and towards the door.
“Halt!” Princess then called her, or rather ordered. That immediately stopped Octavia to her tracks. “Uh... I mean... wait?” Princess Luna then said awkwardly. Realizing that she had almost let the Royal Voice slip.
Octavia slowly turned herself towards the Princess, but found it hard to actually meet her gaze. “I'm... I'm really sorry about this your highness... I... I have no idea how this might have happened, or I rather have a perfect idea why...” Octavia went on with her nervous ramble, while Luna simply stared at her. Feeling her own embarrassment rising.
“It's... it's alright.” Luna tried to reassure the still panicked earth pony. But with little success. “There is no need to be alarmed.” she then said, getting up from her bed. But that didn't help at all, it seemed to make things bit more worse.
“Octavia.” Luna said with raised voice, silencing the earth pony. “Please.” that worked as Octavia stopped her rambling, but still didn't dare to face the Night Princess. “Listen, I'm not mad at you. This is also much of a mistake of mine.” Luna said. Her last words sounded bit sad.
Octavia couldn't help but blush at Princess's words. And the way she looked at her, it was so strange to see the Princess of Equestria acting like little filly who had hard time to admit that she had done something that she might regret.
But even with Princess Luna's words, Octavia still couldn't shake the feeling that she still had done something she shouldn't have done. And that was simply being and sleeping in the Royal Bed and Royal Quarters.
And she then realized another thing, she still hadn't said anything to the Princess for a short while and the Princess could also see that she was still bothered. “Are you regretting this?” she asked, sounding almost, shocked.
There was then a long and awkward silence that felt like an hour for Octavia. “Is it because of my “status” as a Princess?” Luna then asked, and this time Octavia could distinguish sadness from Princess's voice.
And the question for some reason shocked her. Or it was the tone that came from Princess's mouth. Maybe it was both, but she wasn't sure. But it just made her feel even more worse. And also worse about herself and her behavior.
“You are afraid of what everypony might think of you when they might hear about this.” Luna's voice seemed to become even sadder, and for some reason Octavia was sure that some of Princess's words were not only directed at her, but also for the Princess herself. As if she was somewhat familiar with this.
“And I...” there was another pause, thankfully not so long, but still unformatable for Octavia as the Princess's look became even more sadder.. “I can understand if you want to leave and act like this never happened.” then the door behind Octavia opened up slightly. No doubt from Princess's magic.
Now Octavia was feeling completely conflicted. One part of her wanted really to just run away and not looking back, but that was her minor side. The majority of her decided to stay, and face this and maybe in some way repair the damage she already had done.
“I think there is no need for that.”Octavia said, although she couldn't help it that her voice was shaking a bit while she closed the door.
That seemed to take some of the sadness from Princess Luna's face as she gave a small smile, but some remained, while also holding some doubt.
“You said you might have an idea about what happened...” Luna began.
“I have high suspicion of who it could be.” Octavia muttered, but loud enough for Luna to hear. “I'm sorry that I interrupted you Princess!” Octavia quickly corrected herself when realizing what she had done.
“There is no need to that...” Luna dismissed it. “And also no need to bow to me. There are none to judge you. Here, we can be just ourselves.”
Octavia then got up, feeling bit stupid. Of course she didn't exactly have to go all formal on the Princess, but it never really hurt if she wanted to make sure...
“Sorry about that...” Octavia then apologized. “Vinyl is really going to pay for this...” she then muttered.
“I'm sorry?” Luna asked in confusion. She knew the name of the pony, and had little idea of what Octavia was meaning.
“I was talking about my friend, Vinyl Scratch...” Octavia was now almost growling. “I'm was pretty sure that she is the reason behind this...”
“Oh yes.” Luna smiled humorously. “That white coated unicorn who gave us the drinks?” she asked with slight amused grin, which Octavia didn't see or simply didn't notice in her slight upset condition.
“Yes, that's her and no doubt the reason why we are in this situation.” Octavia said, slightly annoyed. “But not that I'm really complaining!” Octavia quickly corrected herself, which Luna replied with a quiet giggle.
“Then, what you say, if we could spent some time together?” Luna then offered. Taking few steps closer to Octavia. “And maybe we could have much more memorable moments than before?” she suggested with a smile.
“I think I'll like that.” Octavia replied with her own smile. “And maybe we could also avoid any kind of hard liqueurs In fact, why don't we just leave alcohol alone this time?” she joked.
“I'd like that idea.” Luna laughed.
With that, Octavia agreed to stay bit with the Princess for an hour. Which turned from an hour to few hours. Most of their talk had involved Octavia's time at the Orchestra and Luna telling Octavia some her experiences as Princess. Also revealing few pranks she makes time to time.
“So you were the one who changed Prince Blueblood's shampoo?” Octavia asked between her laughter.
“Yes!” Luna also laughed. “I was feeling that the pink might be a good color for him!” Luna took a deep breath so she wouldn't suffocate herself from laughter. “It certainly was good for him.” she then said, her laughter slightly controlled.
“That reminds me too much of the time when Vinyl did the same kind of prank for me...” Octavia said, her laughter now sounding bit annoyed. “Which I still haven't forgotten.”
“What happened?” Luna asked interested, with amused smirk. “She also made your mane pink?”
“No.” Octavia blandly said. “Electric blue...”
Luna started to laugh again, which caused Octavia to blush a bit from embarrassment and made a little frown, but she wasn't really offended by Princess's reaction. She had really started to appreciate Luna's presence and was seeing the Princess as different pony from the Royal Princess who shared the burden of ruling over Equestria with her older sister while also taking care of the night.
“And I still need to get her back from that...” Luna was now trying to suppress her laughter, but small giggles still escaped her.
“What's so bad about blue mane?” Luna then asked giggling. To which Octavia was struggling to say anything but couldn't while Luna was now generally laughing at the few expressions Octavia made. And soon Octavia joined the Princess.
Time really flew between them and soon both of them, much to their disappointment, had to leave one another.
Octavia was now standing before Luna's room's door with the Princess. “Well, this certainly has been an interesting day. Hasn't it?” Octavia said amused, while inside she was feeling for some reason nervousness again.
“I have to say yes. But I won't complain because I really had great time.” Luna smiled.
To which Octavia smiled back. “Yes, I have to agree that I've enjoyed our time together.” she then quickly glanced the hallway on her left, then back to Luna. “Well, I guess I'll take my leave then. Goodbye. Luna.”
As Octavia started to leave she heard the Princess suddenly coming after her. “Wait.” Luna called her. Octavia immediately stopped and turned to the Princess.
“Yes?” she asked, now her nervousness had reached her voice.
“I was hopi- I mean, wondering if... if we could meet again at some point?” Luna asked nervously, while blushing rather hard. “Is... is she really...” Octavia thought with a small shock as her heart took few extra beats. No way the Princess was asking her out, but she decided to try if she really was serious.
“I... I think we can.” she replied. “So what you say Princess? Is it a date?” now her heart was beating even faster. And Princess smiled.
And kissed her right on the lips.
“It's a date then.” Luna smiled, which soon turned to a grin when noticing Octavia's shocked reaction. “I hope I'll be seeing you tomorrow. Same place, if that is fine with you of course.” for a moment Octavia didn't say anything as her brain was still trying to comprehend this.
“Y-yes. Sure...” she then replied. This whole thing still feeling so surreal as she slowly walked away. As Octavia walked away Luna returned to her quarters and door closed rather loudly. And that snapped Octavia as she now realized something. “Oh my goodness! I'm having A DATE with Princess Luna!”
