I told you to go right

I figured I'd run into Princess Luna at some point. We followed Aerlion for a few minutes, down corridors that went ridiculously far, up stairs, across balconies, and eventually down the hall that contained the bedrooms of the Princesses.
"Your room is at the end of this hall, sir." the guard proclaimed.
"Thanks. No need for this 'Sir' buisness; we're all stallions here." I replied. The guard looked taken aback, before finally calming.
"Very well." he calmly replied. "Room's at the end of this hall." He pointed an armoured hoof to a set of double doors, which were set beside a set of doors emblazoned with a crescent moon. Just as the four of us trotted past the black doors, a loud creaking was heard as they opened. Aerlion rapidly came to attention; straight, saluting, important. The rest of us went into a sort of half-arsed bow.
"At ease." came her voice. I flicked my eyes up. A pair of forelegs were stood not even a few inches from my snout.
"Hello." I quickly said with a grin.
"Thunder, is that you?" Luna asked. I could tell she was either smiling, frowning, or staring lustfully at my sexy body. Probably the former.
"Yes, ma'am." I replied. "We're not in an informal meeting, so now I have to refer to you as 'ma'am', ma'am."
"Hmmph." she sighed. "Rise." We did so. "What are you doing here with your friends?"
"Well..." I began to explain the whole situation to her; the sewers, the bounty, the letter, Thunderlane, Inferno Cloud, our Geary quest (without the golden gear), everything. By the end of it she was sort of smiling, sort of confused. Finally, after a few moments, she turned to the other three.
"Captain Aerlion, escort these two to their room." she stated firmly, before turning to me. "Thunder Mustang and I are going to talk." The guard saluted, tapped the other two on the shoulder, and they continued next door into the room. When Luna and I heard the door click shut, she spoke.
"Listen, about that evening." she sighed, looking quite regretful. "We were on the balcony under the full moon and stars, I was kind of drunk..."
"You were drunk?" I asked, cocking my head to the right. "I thought-"
"I only discovered the next morning that the spell had begun to wear off. And who knows, if you hadn't stopped us from kissing, we might have woken up beside each other the next morning." she laughed half-heartedly. "Wouldn't that have been weird? I think it'd have been weird. It would be weird. Just waking up beside you, that'd be kind of strange, kind of attractive. Weird." Luna trailed off. She seemed like the sort who would speak a lot when nervous.
"Well, it's no problem now, since I stopped us." I sighed. Suddenly, there was another burst of pain in my side. I winced, bit my lip, and tried to look like nothing had happened. My poker face was ineffective: the princess had picked up on it, and was peering at my side with her neck fully to the side.
"What just happened?" she asked, looking confused. I tried hiding the wound, but a sudden force lifted up my wing. Luna gasped in shock. "Oh, what happened to your side? Does it hurt? Have you tried to heal it?"
"Yes," I replied, "And could you, -NNNGH-, not touch, -NNNFF-, it? I-It still hurts..." My pleas fell on deaf, sexy ears; Luna continued to prod the patch of corroded skin, occasionally narrowing her eyes at a spot, before poking it again. Finally, she sighed.
"That's black magic wounding." she finally sighed. "Only Changelings use that; there's a Changeling in Ponyville. I shall alert the guards. I suppose I'll see you at dinner?"
"No idea, Lulu." I smiled.
"Don't even go there." she growled. "Or I shall go into your mind again."
"You win."

"Thought as much. See you at dinner." Luna and I nodded to each other, before turning and parting ways.

"So," Inferno began the moment I entered the door. He was sat on one of the room's many chairs. "What'd you talk about?"
"Stuff." I replied. "She also asked if we're going to dinner? I dunno if we're invited."
"Pr'b'bly n't." Thunderlane cut in through a mouthful of pretzels. The charcoal grey stallion was stood near the room's fridge, leaning on the counter near a bowl of pretzels. "P'zza guy'll g't h're firsht."
"Cool, we're getting pizza?" Inferno grinned, sitting up from on the couch. Thunderlane shrugged, and finally swallowed the biscuits.
"Dunno. Might call for one." he replied, pointing to the phone.
"Wait, I didn't know Equestria had phones..." I trailed off, peering at the large device hung on the wall. It looked like a 50s payphone. I looked back at Thunderlane. "They have computers here, too?"
"Yes, but they're fucking gigantic." Thunderlane snorted. "Biggest we've got fills the whole room, and has 1GB of data." I missed what else he said, because I was laughing so hard, alongside Inferno.
"One gig?!" I laughed. "One fucking gigabyte?! My house computer has like 2 fucking terrabytes! NASA's supercomputer is like a thousand times more powerful! And Equestria's best computer has 1 gig?! That sucks!"
"1TB?" Thunderlane asked. "So it goes 1 byte, 1 gigabyte...that's it."
"No, byte, gigabyte, megabyte, kilobyte, terrabyte. I think."
"Fuck, where's your world gonna be in 20 years?"
"Wow, Thunderlane, I've never heard you swear." Inferno cut in, looking amused.
"Yeah, bet you've never seen Equestrian porn, either." he chuckled. My ears pricked up.
"Porn? Wheresa porna? Me like porn!" Inferno began saying.
"Same. Didn't know you could make porn..."
"Gets realistic eventually, especially with the software we can pack onto 20 byte home computers. Somepony even managed to make a three-way between the princesses and a guard." Thunderlane proclaimed proudly.
"Awesome."
"The pictures were removed from public view, but apparently a tall, white furred mare went into a shop in disguise, bought one magazine containing the image and left."
"Ha," Inferno laughed. "Wonder who the hell that was..."
