Dear Diary,

I can’t help but feel an urge to throw myself of a cliff or something. Less trouble than dealing with shapeshifters and magical people in the longrun…

I opened my eyes, the sun just rising. I could see Rarity, Twilight and Rainbow sleep on the other side of the carriage. Pinkie, unlike when I closed my eyes, was not in my bed anymore. Ponyville was visible on the horizon.

“Good morning!” Molly greeted me when I got out of the bed and started to put my clothes on. I just rolled my eyes and ignored her, wondering where Pinkie had gone. Since it wasn’t the first time she was gone when I woke up, I didn’t think too much about it, before it.

“Twilight,” I whispered and shook her gently. She opened her eyes almost immediately, as if she hadn’t been asleep at all. “Meet me in the other carriage.”

I noticed that the veins in her eyes were very visible, and she had gotten back a hint of the dark rings under her eyes. She just nodded and closed her eyes again. Letting some time pass between I left and she followed might be a good idea, just in case.

As I closed the door behind me I wondered if I had done something I shouldn’t have. Asking Twilight to speak to me, with two potential witnesses, would be suspicious. And if the Changeling was one of those, it could be even worse. Maybe it would give away that Twilight knew I wasn’t the one.

I sat alone in the carriage, waiting for Twilight to join me. If Rainbow or Rarity heard me… and where were the rest of the folks? Applejack, Pinkie Pie, Flutter, and Spike were missing from the picture. A feeling of restlessness came over me as I could feel the time drag itself along.

She had probably just fallen asleep. I had been up all night enough times to know that even though you believed that just a few minutes on the eye wouldn’t hurt, you fell fast asleep rather quickly. And subsequently overslept and caught hell for it later, if you had something important to do that day.

My spirits rose in my chest when the door started to open, but fell down again once I saw that it was the blue girl and not the purple girl that came through. Great. Just fucking great.

Rainbow Dash was dressed a bit out of the usual, or so my brain registered it, with loose, though not quite baggy, jeans, a black tshirt with a logo that read “Wonderbolts” and a blue and white headband. Her hair was fixed in a ponytail.

“Hi,” she started and took a seat opposite of me. “Slept well?”

“Sure.”

I wasn’t able to read anything into her or what she wanted out of the question. It had to be building to something. Her eyes seemed to flicker from one side of the carriage to the other every few seconds.

“What do you know about what is going on?” I raised my eyebrow at the question. So she probably did notice that I said something to Twilight. What would I answer to such a question? “You seem to be keeping an eye on everyone, but I was told that you don’t know what is going on. So spill the beans mister, or I’ll make you!”

Rainbow had spread her wings and launched at me before I even noticed that she did, holding me up against the wall. As intense as her voice was, she remained quiet to avoid getting any attention. My heart started to pump furiously in my chest.

“Rarity told me what happened in the infirmary. She told me she believed you to be the Changeling, but couldn’t force you to show your true colors. And now I see you whisper things to the Princess. You’re not the Changeling, are you? Huh!? Are you!?”

What the fuck just happened!? I just shook my head, trying to not look as scared as I was. She had picked me up and flown me pretty effortlessly before. She, seemingly like everyone else in this place, seemed to have a leg up on me physically. No need to pick needless fights.

As she let go of me, I had to wonder: If I were the Changeling, why wouldn’t I just lie and say I wasn’t? What was she playing at? This was going to give me a headache if she didn’t explain it. I seriously had to consider her a major suspect in this from now on. The only thing that made sense to me was if she was the Changeling, which would be bad. But, if I worked from the assumption that Molly, the headaches and the passing out was connected to the Changelings, she simply couldn’t fit into the picture. I had been alone with her once before and I had no problems recalling that episode.

“You… don’t think I’m a Changeling?” I asked, hoping to not sound as nervous as I was. “Why?”

“You’ve had too much opportunity to get a hold of many of us, yet no one objected to Luna telling us that she and Celestia believed you to be the Changeling,” Rainbow walked over to the door and peeked through, checking if someone was coming. She repeated the action on the other door as well. “Fluttershy’s the only one who have been willing to show you any mercy so far, but that is just how she is. The rest of us have been so sure that Celestia was right, but I don’t know anymore. After you and Twilight were gone… I think you two have learned that the Changeling is someone else.”

I couldn’t help but let my mouth hang partly open for a while, just staring at her. She looked really self-satisfied with my reaction too, as if she had won some game. What the hell was I supposed to say to this? If she was the Changeling, confirming this would make it a fuck of a lot worse. If she wasn’t, she could help us.

“What does a Changeling look like?” I asked, hoping to postpone the inevitable shitstorm that this would create.

“Wait, seriously, you don’t know?” Rainbow let out a laugh, mocking and arrogant. Then she suddenly stopped and raised an eyebrow at me when I shook my head. “O…kay… Well, when they’re not looking like someone else, they have black skin…”

First reaction I got was that this sounded a little bit too familiar for my tastes. If Rainbow continued to say they had horns and insect-like wings I would probably freak out.

“… and they have really creepy wings, like an insect, and they have horns. Their eyes are weird too. They look like, I dunno, corrupted Alicorns or something.”

Alicorns were the likes of Twilight, I seemed to remember. I could practically feel my skin getting paler and paler as the room started to spin a little. Molly was a Changeling. I shouldn’t be surprised, but now I had some confirmation. Now the question was how she had gotten into my head, and what it meant. And what that meant for Rarity.

And for Rainbow Dash, a part of my mind reminded me. If she had been the Changeling, and Molly was the Changeling, shouldn’t she have known that I somehow was under an influence like that? Did this mean I could trust Rainbow Dash? If there had been others around for this little interrogation, I would distrust her in a heartbeat, but we were alone. And Molly seemed to be a recurring theme in my mind, probably connected to the memory loss and headaches. I really needed to talk to Twilight about this.

I felt my back being pressed against the wall again; Rainbow looked worried and was holding me up against it, firmly, but a lot more gentle than when she started this little escapade. A Changeling had gotten into my mind somehow. I could only hope that it didn’t allow it to read my mind, because if it did, we were fucked already. Maybe it was just a figment of my imagination, coming about as a representation of being affected by the Changeling, however that worked.

“Twilight!” Rainbow Dash yelled and started to drag me into the other carriage again. Twilight, looking like she had just woken up again, jumped to her feet and helped the blue one getting me into one of the beds.

“What happened, Rainbow Dash!?” she sounded angry, but I gestured for attention. My head had stopped spinning, if just a little bit.

“Nothing, I just… I just- I must have had too little to eat lately. I feel exhausted.”

“Nothing like inciting pity to get to feed on us,” Rarity too had gotten to her feet and scoffed at me. I just ignored her, but both Twilight and Rainbow seemed to give her a suspicious glance. Or maybe that was just me thinking that they did. I couldn’t see a trace of it after I blinked. She didn’t seem to notice it either.

“Here, I have an energybar in my pack,” Rainbow jumped into her bed and dragged a sports bag to me, taking out something that looked a lot like those small chocolates that supposedly had a lot of protein and stuff, practically stuffing it in my face. Rarity let out an angry ‘hmph’ and walked out, slamming the door behind her.

Rainbow hasted over to the door and checked if the coast was clear. This was the last one on the train, so there was only one door to check, so she came right back.

“What happened?” she asked, looking at me skeptically. “Why did you almost faint again?”

“I… I think the food thing was it. I feel much better already.”

I did feel much better, now that the initial shock of the confirmation of one of my fears had started to fade. But what would I tell Twilight about Rainbow? I didn’t think she was the Changeling, but my reasons might not be enough for her. Unless I told her about Molly. Who was consciously absent at the moment.

“Rainbow, what is going on?” Twilight’s voice held a combination of anger and worry.

“I don’t think he is the Changeling, that is what is going on. And I think you know he isn’t, but is allowing the rest of us to think he is. And I want to know why.”

Twilight looked just as shocked as I had, with her mouth partially open. I could practically see her trying to put the pieces together to see if she could trust Rainbow.

“I think we can trust her,” I said, getting an even more confused look from Twilight. But I wasn’t given any chance to continue, as her horn lit up and forced my mouth shut.

“Umm, Twilight?” Rainbow sounded nervous. “I don’t think… forcing him to shut up is such a good idea… If I were the Changeling, that would look really suspicious.”

“Ugh, fine,” Twilight released me again, starting on an angry tirade directed at me. “Shows how much I can trust you, spoiling our secrets like that. We weren’t supposed to take any chance, but now you’ve told her everything. Great, this is just great. You might just have told the Changeling about our plans and that is just great…”

“Umm, Twilight?” Rainbow took the word again. “He didn’t tell me anything. I confronted him about this…”

“What!?”

“She’s right, Twi, I didn’t tell her anything,” I broke into the conversation, firm and a bit angry in tone. I had to tell her about this Molly thing, but if she didn’t shut the fuck up, this was only going to get worse. “So can I please get to tell you why I think we can trust her?”

Twilight looked like someone had given her a straight jab on the nose, so she just nodded and sat down by the bedside. Rainbow looked at me, no less surprised than Twilight.

“Earlier, when I passed out,” I began, unsure how to continue. “Well, I think I passed out because I tried to force myself to remember something I’m not supposed to. I’ve been having a lot of headaches lately, accompanied by what I believed to be hallucinations. And now I think it is something far worse than that going on in my head. Please, let me finish…”

I added the last part because I saw Twilight’s mouth make an ‘oh-oh’ reaction. If she had been dealing with the Changelings before, she might be familiar with what I was about to tell her.

“They started a day or two before we went to Canterlot, but I didn’t think much about them. I thought it was just a side-effect of Pinkie’s magic cupcakes, or just from me being transported here to begin with. But then I started to hear about the Changelings, and now that Rainbow described to me what they look like, I think I have encountered one before we became aware that one was here. And I think it did something to me to prevent me from remembering it.”

Twilight and Rainbow looked at me, dumbfounded. But before long, Twilight asked me how I could know that Rainbow was not the one who did this.

“Well, I only spent time alone with Rainbow once, and that was before this started to happen. That was the day Pinkie made those cupcakes,” Twilight nodded as she followed the story. It seemed to make sense to her. Rainbow, on the other hand, had gotten a deep blush. “And I remember this encounter just fine. And I remember going out to the Cutie Mark Crusader’s clubhouse in the evening, per Sweetie Belle’s invitation. And I remember this just fine too. It is after I left their clubhouse I started to get the headaches and this hallucination started to appear to me. And if Rainbow was the Changeling, I don’t think she would confront me like she did just now. If I was already under her influence, I’m sure she could have just made me tell her what I knew, without the need for getting you involved.”

“Not if she wanted us to trust her,” Twilight still seemed skeptical. “But… if this started to happen after the day Pinkie made cupcakes… Are you saying the Changeling is one of the Cutie Mark Crusaders?”

“No, I’m saying I don’t think Rainbow is one.”

“You said this started to happen the night after Pinkie Pie made her crazy cupcakes?” Rainbow asked. “Didn’t I stop by to borrow one of the new Daring Do books from you that night?”

“In the evening, not that night.”

“Oh, right. I guess I can’t prove I was home alone reading that night…”

“You shouldn’t have to prove it,” I objected. “She has not been tied to any of my headaches, and my headaches started to come after I left the Cutie Mark Crusader’s clubhouse, in the middle of the apple orchards.”

“Are you saying Applejack is the Changeling?” Rainbow asked.

“I… maybe. She wouldn’t have been suspicious out in the orchards at night, and didn’t Luna say she saw something there when out flying?”

“I dunno…” Rainbow continued. Twilight remained silent. “Rarity has been acting a little strange lately. She got really angry over nothing the day before we left. Didn’t seem like her.”

“I think Rarity is in the same situation I am in. I confronted her about it before I passed out and she seems to see this ‘hallucination’ too.”

“This is… I don’t know what to think,” Twilight finally joined the conversation again. “You’re speculating too much. The princesses already proved to be wrong once about whom it was. And thanks to you, we just got to trust that this is the real Rainbow Dash.”

“Isn’t there a spell or something that you can use to prove she’s the real one?” I asked. Luna had done something like that, so why not Twilight?

“I… I don’t know. Just- just leave me alone, will you? I need to think…”

A flash of purple light later and she was gone, probably in another part of the train. Rainbow and I looked at one another, unsure of what to say next.

“Hey, eh, thanks for, you know, standing up for me.”

“Don’t mention it,” I said, in the typical sense one would say that, but continued. “I mean it. The more you’ll push that, the more I’ll regret doing it.”

“Oh…”

Well, I felt a bit like a jerk saying that, but it was true. Her thanking me wouldn’t exactly make me any less suspicious of her. I felt like I had done the right thing choosing to trust her, but there was still the nagging presence of one crucial fact: The Princesses had been wrong regarding me. I could easily be wrong regarding her. Not that it really mattered what I did, since she had figured it out by herself already, but making it easier for her could have been a bad thing.

“Ah! What are you doing?” While lost in thought, Rainbow had started to unbutton my pants.

“Umm, make up sex?” Making up for what? Even my mind wouldn’t have gone to sex in this situation, but hers did? Who was I really dealing with here? I just stared flatly at her, though I did feel that blood started to surge to the appropriate places.

“Umm…”

“Fine!” she seemed annoyed, but completed her work with my pants anyway. “I’m still in the middle of my heat period and I can’t take it any longer! And your friend doesn’t seem to mind.”

Okay, heat season. I vaguely recalled that being mentioned as a thing by someone after I came here. And I did remember Rainbow being in hers a couple of days ago, so why not still be in it? I had about zero idea of how long these periods would be anyway. I would still argue that the timing couldn’t be more shit than right now, but maybe this would take the edge of my day. I still had to wonder about this semi-rape thing Rainbow had going though. Or maybe that was just her going crazy over bottling it up.

“Ah…” her tongue moved from the base of my ‘friend’ to the tip with an unusual speed. Not a speed that, in itself, was surprising, but because it was like if she tried to get some of the foreplay out of the way.

Almost unwillingly she took a step back and let her own pants fall to the floor of the carriage. She had long socks that almost reached up to her knees, colored much like her hair. On the top they were unevenly folded because her pants had dragged them downwards.

Her panties were white with light blue and gold trimming on the edges. Coming back over to me, she turned her back to me as she sat down on my lap. On the backside of per underwear there was a logo of a lightning coming from a cloud, with wings coming out from the side. I was close enough to read the fine print, which said “The Wonderbolts of Cloudsdale”. My member was gently being rubbed against the logo before Rainbow adjusted her position again.

She raised herself a little and reached her hand in between her legs and bent me a little forwards. When she came back down, I could feel my shaft being pressed against her entrance as she slid herself along it. I started to feel fingers play with it through the fabric, which became more and more damp to the touch. From my position I would see that Rainbow had closed her eyes as she did this.

Seeing my chance to get in on the fun, I reached around her with my arms and pushed her hand aside from between her legs. Instead of replacing them with my own, I pulled the panties aside. With my other hand, I tried to lift her up just enough to readjust my position. I couldn’t do it with one hand in my position, so I felt she helped me out a little.

As I slowly pushed inside of her, I was pressed up against her, feeling something unusual as I did so. Rainbow’s wings were folded on her back, which was pressed against me. They felt a lot… they felt strange the way the bones pushed against me, made comfortable by the feathers that covered them. They tickled a little, but luckily, because I still wore my shirt, not all that much.

Only a couple of seconds passed before she virtually slammed herself down on me, tired of the slow pace I held. My hand, which was still in her panties, couldn’t keep up with the sudden change of pace and was left behind. To make up for this, I reached in under her shirt and started to feel her chest. She wasn’t wearing a bra.

By the time I got my hand there, she had already started to grind furiously. I thought I could hear her breathe something, but it was too low for me make out. I started to play with her nipple between my thumb and index finger, prompting moans that interrupted her breathed mumbling. My other hand, no longer working to lower her onto me, was placed between her legs, gently, almost teasingly, rubbing against her clit. Almost immediately I felt and saw her squirt out on the carriage floor.

“Damnit!” she mumbled, pulling herself halfheartedly off me. “I was… too slow… it took at least fifteen seconds…”

As she landed on her stomach on the bed next to me, the comment she had made about “ten seconds flat!” from the first time we had done this replayed in my mind.

“Okay… do whatever you want to me then…” Rainbow threw a glance at me, a little distant looking still. My first reaction was to just look confused. “Come on, you got me off, so do what you need to get off too…”

It still took a moment or two before I registered what she was saying, so she adjusted her position a little, putting her hindquarters up just enough for me to snap out of my trance. The previous time I had been with Rainbow, I had had plenty of fun with her pussy, so why not take advantage of the situation?

Remembering something Pinkie had done, I got to my knees on the bed behind her, pulled the Winderbolts panties down to her knees and started to run my fingers between her soaking lips. After I felt that they were sufficiently wet, I gently started to prod her ass with one finger. I saw her swallow and glance back at me, but she didn’t say anything as I pushed it inside, trying to get as much of it lubed up. She covered her mouth with her hands when I added a second finger.

I could almost see myself blow it right then and there; her expression betrayed both a feeling of excitement, but also that she was nervous and a bit anxious. Wanting to tease her, I decided to draw out the foreplay. She had started to leak again.

Acting as if I were unhappy with the lubing I had given her, I started to amass what spit I could muster in my mouth, drawing out the process further. While I did this I continued to gently move the two fingers in and out, at a slow pace to torment this fast-playing girl.

I let my fingers get deep before I quickly pulled them out, when I had enough spit in my mouth, to get as much out of the reaction she was sure to give me as possible. She closed her eyes and buried her face in the bed when I did, but hastily turned her head back to look at me when the saliva from my mouth fell down on her hole. With a smirk I began to guide what I could into the hole itself, introducing my fingers to rub the ‘lube’ in properly.

Rainbow had to use her hands to help her stay as quiet as she got while I did this. With my other hand, I repeated what I had done earlier; running a couple of fingers between her lips to get them wet. Now, however, I made sure to give a little push on her clit every time I came by it. Each time it was met with a suppressed moan.

“I- heh- I don’t think… that this is a good idea…”

I had retracted my hands and started to prod my erection against her asshole. Because of the extensive lubing I had given it, it felt like I was going to be able to push far in right away, if it wasn’t for Rainbow doing her best to keep it tightly locked.

“You enjoyed me fingering you there,” I reminded her.

“But, eh, I’ve never taken more than a couple of fingers before!” she protested back.

“You said I could do whatever I wanted to get off… and if you liked my fingers there…”

She didn’t reply to that, except by trying to relax. I felt that the resistance I had met was reduced a bit and without using more force, my head went further in. a tiny bit more and it would be inside. I pulled myself back ever to little, and pushed forward as best I could.

“Gah!” the moment my head was inside Rainbow wasn’t able to relax anymore and I felt that she pressed her ass together to the best of her abilities. Already in her, I continued to push, slowly and firmly. Rainbow panted heavily and loosened up a little bit the further into her I got.

In an attempt to make her enjoy it more, I reached around her and in between her legs with my right hand and continued where I had left off. Almost instantly I felt she squirted again, which made her tighten up.

A lot of pressure had already built in me, but I wasn’t quite there yet, so I continued to try to push inside. When this proved futile, I started to pull out, met by another collection of muffled moans from Rainbow, and pushed in as far as I got once more. The response to this was some not-quite muffled moans.

To see how deep I could get before I threw in the towel, I placed both of my hands at her hips and retracted myself a little bit from her depths. Moving lightly back and forth in hope to throw of her suspicion for what I was going to do, I prepared to push as hard as I could.

“Ah! You’re tearing me apart!”

When I thrust into her, I got almost balls deep before it stopped. If I was tearing her apart, she was close to keeping me buried within her forever. My member simply wouldn’t move when I tried to push or pull, so tense had she gotten.

Feeling I was within reach of an orgasm, I started to move myself in circles as best I could. Rainbow, over the initial shock, did begin to relax again, but it didn’t allow me to push any further in. I was buried as deep in her as I was going to be. A few seconds later I felt that I started to pump out my semen.

“Ah, that… wasn’t so bad…” Rainbow gave me a tired smile as I began to pull out, the effort being made infinitely easier as my erection subsided. “We should… totally do that again sometime… even if you’re too slow to get it done in ten seconds flat…”

Just as she closed her eyes, a loud whistle filled the air, followed by someone announcing “Ponyville Station” outside the carriage.
