The train abruptly screeched to a sharp halt, causing a small cry of surprise from the others. I let out a cry of pain, since I was thrown forward and had my horn embedded in the wooden wall up to halfway into the surface. "OW, MY GIANT BLUE HORN." I yelled, before getting my forehooves on the wall and pushing. After several attempts, it became evident that I'd need help. "Twilight?"
"Yes?" she replied, placing a hoof over her mouth to cover her blatant grin, like everyone else in the carriage.
"Halp plez." I sighed. She giggled, and ignited her own horn, and with a sharp tug I was out. I landed on my flanks, and felt really awkward since I was so big. "Danke." I said calmly as I stood/crouched slightly in case I hit the roof or doorframe. In the wall where my head had been, there was a hole. We all nodded solemnly at each other, and knew what to do.
Twilight lit her horn rapidly, and teleported us away, leaving some other sod to get in trouble for the damage. We found ourselves stood outside Gustav's Café, ponies only just realising that the Elements and their lovers were stood with a new alicorn, and he was a stallion. Instantly, there was silence.
"Um..." Twilight winced at the awkwardness. "...hi...?"
"Aye." I added calmly. My voice carried through the air, as all of Ponyville from what I could tell began to approach so they could see the new Alicorn. I rolled my eyes and groaned. "Oh, piss." I grumbled at the crowd's intrusion, before turning to the girls. "Can I go home, now?"
"No, Marine, you can't just yet." Rarity answered. "We still haven't had lunch."
"But I could get lunch at ho-?"
"No." Twilight facehoofed.
"...well...c-can you explain why no-?"
"NO." came the firm group reply. I hung my head, which surprisingly went to their head height.
"Plez?" I asked.
"I will slap your shit." Fluttershy snarled, raising a hoof violently.
"ALRIGHT ALRIGHT I GET IT." The crowds stared on blankly. They know him? I groaned. "Yes, they know me." I said out loud. "Don't be so amazed and shocked: You all do as well." Confused murmurings and glances were passed.
"No we don't, Mr Godlike-Powers." a mare I recognised as Roseluck stared back with her signature, adorably worried face*.
"You know Thunder Mustang, yes?" I replied. There were cautious nods and facehooves, as well as grumbling about 'did she really do him?' "Silence your mumblings. This new form has been accepted by Princess Celestia and Princess Luna, my ~~waifu~~ loving marefriend, and I now have permission to use it in public. Expect to see more of this."
"Can't wait to see more of those bad boys." Colgate giggled from a table with Berry, Cheerilee, Octavia, Vinyl, Bon-Bon, and Lyra. Either in jest or a legitimate sign that I was kind of hot, she licked her lips with a seductive grin. Thankfully, the crowds had scattered before anypony but the girls saw my red face.
"Thunder," Twilight began, "I think you have a secret admirer group."
"Yes." I nodded as all 11 of us plus Dr Dr Dr Leftenant Commander in Chief Spike began to head for the library.

I was once again after a long while woken up by Twilight murmuring and flipping pages. The guys were sleeping at home, but since our house was too far and it was raining, plus Twilight wanted to find out about Alicorn anatomy, I was also sleeping by the bookshelf. Unfortunately, this meant that to reach some books, Twilight was pushing either her nether regions or her ~~flanks that even I liked~~ bum into my face.
I found it to be both an interesting, arousing experience when she fell over and landed on my face.
Errm, a-anyway, when Twilight was just over my head, she dropped a book on my face, and unsurprisingly it went into my eye and bounced and went in again. I sighed at the pain, and simply stood up. Twilight rolled her eyes as I purposefully placed my neck against her face and glared down at her 'angry-Lulu' style.
"Seriously?" she sighed, adjusting her glasses. "It's just us two here in the library at the moment, and you're going to stand in front of me like you're going to suck my horn?"
"You were the one who was nearly purposefully shoving your love-juice maker in my face, and just so happened to 'fall' on me and take about 20 minutes to get up." I shot back. "Then you did it again, but with your ass."
"Well, I was...eh..." Twilight began to slow down, shrivelling and blushing, whilst rubbing a leg with a hoof. I cocked my head and raised an eyebrow.
"Yes?" I said impatiently.
"...enjoying the feeling when you tried to talk but rubbed it up in a good way with your mouth?"
"Oh wow." I groaned. "And you're seriously with Inferno? Hold those lusts in, woman!"
"I can't help it!" she cried, practically breaking down into tears. She looked pitiful. "Ever since you picked up that infernal sword, an-and got Nightmare into your body, you-you...changed how I see you. I don't know what happened, but you're tall, dark, dare I say handsome, you fight evil, bust crime, save lives, and now you're an alicorn?! How is that not attractive?! Even I WANT YOU! I have to be losing it or something for this to happen! I already have someone who loves me, keeps me company at night, and now I have an eye for YOU? The fuck is wrong with me?!" The once great unicorn was now on the floor in tears, huddled up in a way that made her seem so tiny. I frowned, and looked at one of my hooves. Then, carefully, I knelt down next to her and put a hoof on her shoulder. She snivelled slightly, and looked up in confusion. I stared blankly at her for a moment, thinking of what to say.
"...there there." I said in a monotone voice. I almost heard a studio audience laughing. Twilight looked like she was trying either not to laugh, or continue crying, and I was hoping for the first option. After another moment, I tried putting on a comforting smile, which evidently came out as a rape face. "~~Sheldon's~~ Thunder's here...?" I groaned loudly, and smacked a hoof on the floor. "Damn it, it didn't work." I sighed.
"No, no, it's fine." Twilight assured, shaking her head. "I-I'm just kind of frazzled from the past few days. I just haven't sat down with a magazine and ~~clopped~~ read for a while, or spoken to somepony as a friend rather than bodyguard, lover, or anything. It's be nice if...we could sit and talk?"
"Aye, sure." I smiled. "What did you want to talk about?"

~~And nothing sexual happened~~ So we just talked. About...everything, really. It went from friends, to the awkward point about sex, then onto politics, science, news, all sorts. Then, that's when I remembered something. The note from my house to the graveyard. I raised a hoof.
"Twilight, can I ask a question?" I asked.
"Sure, what is it?" she replied. I levitated out the small note.
"Do you believe in ghosts, by any chance?" Twilight blinked at the question as she carefully took the note. She cast her eyes onto it, then looked confusedly back at me.
"Where'd you get this?" she murmured, putting her small reading glasses on and once more hovering over the page. "I didn't know there was a cemetery near Ponyville. Who gave it to you?"
"That's the weird part; Y'know when I said I'd seen a ghost? I wasn't lying. I went to a run-down part of Canterlot early in the morning, and there was this mare. She had a hood, but gave me this and told me to 'go there on Nightmare Night'. Then, she...faded, I suppose. Just out of view. I can only assume this is going to lead up to something, and that this cemetery might only appear on Nightmare Night." Twilight nodded slowly, before getting up and moving to a cabinet. She looked at the contents for a moment, namely books and scrolls, before levitating out a blue backed book, with a skull on the front.
"Supernatural events probably have some form of link if they tell a living creature to go someplace at a certain time." she read from the book in explanation, "Ghosts will usually have an obsession with objects or places they had an emotional attachment to in life."
"So she might have someone buried at this graveyard that she dearly loved?" I asked.
"I'd assume. Let's see if we can find anything about this mare." Once again, Twilight got up, put her book away, and moved to another shelf. She grabbed a book of similar appearance to her other book, and sat down with it again, before flipping to the index. "Which street was this encounter made on?"
"Haydon Road." I responded. After a moment, Twilight flipped through to a page, and right there was an illustration of said mare. "Yeah, that's her." I said, pointing my hoof to the image.
"So, it's her." Twilight began. "Apparently her name was Phys Fun. She was around before Celestia and Luna, and died at the start of their rule by the hooves of a lynch mob. According to those who knew her, she had a strange obsession with a cemetery outside Ponyville, and she'd spend days at a time there. Said graveyard apparently contained creatures and freaks from a different universe made out to be 'sillier' than ours, but with highly dangerous creatures. It turns out that she was planning to resurrect them all and bring a new era of chaos for herself, but obviously misunderstood the line 'We're heard to lynch you'. Her famous last words were evidently NOT creepy, when she said 'I'm not done, mongrels. Not by a looooong shot.' So, we're dealing with what may as well be a ghostly necromantic witch who had ties with Discord. Fun."
"Are we gonna tell Celestia about this?" I asked. "I mean, if something goes wrong, yeah, I'll have weapons, but these are apparently powerful creatures. It'd be good to have extra firepower from the sun goddess."
"She'll be too busy." Twilight sighed. "Hell, she'll probably be asleep. In fact, you'd probably be more powerful than her by October, so why do we need her with us?"
"I suppose." I muttered. "But are we all gonna go?"
"We should ask them tomorrow." Twilight said, standing up. "But now, I get the feeling we should be going to bed. You've got to settle back in tomorrow."
"But you still didn't look at my anatomy." I noted. She paused, and looked up for a moment.
"Damn." she sighed, facehoofing. "Go downstairs, and strap yourself down. I'll go get everything I'll need."

So...I kind of...me and her...yeah.

"I did not know you could make such nice sandwiches, Thunder." Twilight said politely after she had finished touching my wings and horn. It was a while, it was ticklish, and there came a point where she nearly used her tongue for something to do with my hooves, but otherwise, she was going to report these findings to a university and get a rather nice income of 400,000 bits. We were both in the kitchen.
"I know, right?" I replied. "Maybe it comes with alicorn magic that it adds flavours to things."
"My magic makes things taste like passion fruits, so I suppose it's that."
"Because I mean, I'm getting a hint of blueberry muffins, that the same for you?"
"Mmm, I get more of a taste of...ummm..."
"What?"
"Well..."
"Go on, I won't be insulted."
"...lady cum."
"And you'd know how that tastes?"
"Remember I had that 8-way in Appaloosa with the others?"
"Uh-huh."
"Rarity's tasted like peaches."
"Mind if I taste yours?"
"Sure, go ahead."
-totally canon sex scene here that I didn't do just because Twilight R34 is actually kinda hot-
"I can see where the taste of blueberry muffins you're coming from is. I get that taste too, did you make these different?"
"No, I didn't."
"What do you taste from my sandwich?"
"Yeah, I can see why Inferno likes you."
