After a peaceful night's sleep I spent the next morning working on a little project of mine. It was something I had been putting off for a while, but considering all that was happening now seemed like a good time to get started. It'd help take my mind off things for a little while at least.

Heck, I was so excited to finally get to work that I hadn't even gone down for breakfast. An oddity for me, for sure, but nobody even came to check up on me until late morning when I heard a knock on my door.

"Come in," I shouted from my seat at my writing desk. The door latch clicked as it opened and Twilight poked her head inside.

"Good morning, Ben. I just came by to see how you were do-..." She paused, staring at the newest addition to my anatomy. "You have a tail," she said matter-of-factually.

I glanced down at my new appendage as it casually flicked to the side a bit. Thankfully I was sitting on a standard folding chair so that it could just poke through and out the back. The hair was a deep burgundy color with a few streaks of a lighter shade of red.

My new tail was actually the main reason I had stayed up in my room that morning; I was too busy just staring at it and getting it to move on command to bother with breakfast. It also meant I was definitely going around sans-slacks from now on. No way was I going to try modifying one of my pairs of pants on my own. Oh, sure, Rarity wouldn't mind helping, but I didn't think it would've been right to bother her over something this trivial.

"My hair's starting to change color too," I said. "If you look closely, you can see the change at the roots."

Twilight fully entered the room and approached me. She then got a real close look at my scalp, seriously invading my personal space. "Oh, wow, I can definitely see it. Looks like your changes are definitely on track."

"Wonderful," I said with as much enthusiasm as I could manage (i.e. almost noil). I then shook Twilight off me and went back to writing.

"What are you working on?" Twilight asked.

"Script," I replied. "I figure that, if I'm going to be staying here permanently, I might as well introduce some familiar culture. So, I'm writing out the script for one of my favorite movies." Twilight looked over my shoulder. Didn't anyone tell her that's rude?

"Star Wars?"

"Hey, it's a cinematic masterpiece back home," I retorted. "Plus, it's one of the few movies I remember by heart. It'll be a challenge to adapt it for a pony audience, but I figure that it'll be just as popular here."

Twilight didn't answer right away. I could almost feel her hesitation. "Well, you might not have to do that, Ben."

Okay, consider my interest piqued. "What do you mean?"

"Well..." Twilight started, pausing as if searching for the right words. "I'm starting a new project today. It's... related to your.. condition."

"I thought there was nothing to be done," I said bitterly. "That it was too late for me."

Twilight placed a hand on my shoulder. "Maybe for you, Ben, but it's not too late for any more humans that might end up in Equestria in the future. You heard the Princess; a human ends up in Equestria on a semi-regular basis. With a little research we might be able to figure out what's causing it or, barring that, a way to send them home."

I blinked. "I thought we exhausted every avenue on finding Earth?"

Twilight nodded. "I thought so too, but I found somepony to lend a hand, one who has extensive experience with magic dimensional portals." She then smirked playfully. "Come down to the lab. You'll find out everything down there." With that, Twilight Sparkle left my room, closing the door behind her.

Me, well, I was stunned. Twilight actually found someone that had more knowledge than her about something magical? This I had to see.

I should've expected it. I really should've. In hindsight the identity of Twilight Sparkle's so-called portal expert was super obvious.

But let's backtrack a bit. On my way down to Twilight's lab I stopped by the kitchen for a light morning snack. It was just a slice of buttered toast, but still enough to tide me over. Deciding not to keep Twilight waiting too long I scarfed it down on my way to the basement.

Once I saw who Twilight got it took all my willpower not to facepalm. It was someone I had met before, although it was my first time seeing her as a pony. Still, despite the species change I would recognize that red and yellow hair anywhere, even though she had forgone her usual leather jacket and instead wore a white lab coat.

Still, despite being annoyed with myself, I was glad to see her. "How's it been, Sunset?"

Sunset Shimmer looked up from the workstation she was sitting at and smiled. "Hey big guy. Lookin' good."

I blushed as I bit back a groan. Damn these ponies and their nicknames. "What brings you here? Isn't today a school day," I said teasingly.

Sunset scoffed. "Please. I was at a college level when I fled through the mirror the first time. The only reason I need to go to that school in the first place is history class; which I'm acing by the way." That last part just had smug oozing out of it. "Besides, Principal Celestia gave me a few weeks excused absence so I can work on this project."

My mood fell. "You're taking time out of class just to work on my transformation problem? Didn't Twilight tell you it was pretty much a lost cause?"

"Not that project, the other one. The portal project." She paused a moment to take in my uncomprehending expression. "Twilight didn't tell you?" I shook my head. "Figures. Anyways, you know how Twilight's been searching all over the multiverse for your Earth?"

"Yeah..."

"Well," Sunset continued, "she finally decided to bring in an actual expert on magic portals."

It took me far too long to get where she was going with this. "You mean to tell me that you can find my home?"

Sunset's ear-to-ear grin lit up the room. "That's right. Well, I have a good idea, at least," she said, hedging her statement. "I won't bore you with all the technical details, but the other Twilight and I have been doing some independent research on multiversal portals and we think we've found a way to trace an origin point for anyone who's been through one."

"But I didn't come through a portal," I protested.

"No, but it's the same principle," Sunset rebutted. "It won't be a hundred percent accurate. There's always margin for error when working with something of this magnitude. Still, I believe we can get it on the same continent at the least."

It was hard to keep my excitement tempered, but there was something that still needed to be addressed. "What about the whole... you know." I circled my arm around my torso.

Sunset's excitement dampened a little as I indicated the elephant in the room, but it didn't go away completely. "To be perfectly honest, I don't think this will help you with... that," she said. "My work's still in the very early stages; it's almost purely theoretical at this point. Even with my most optimistic estimations, by the time I can get a working portal to your homeworld you will have been a pony for a month." Well, that was a mood killer if I ever heard one. "But, it could help someone else in your predicament. If another human appears in Equestria, we'll be able to send them right home."

I had nothing to say to that, so I simply nodded. As I did, I inadvertently got a look at just what Sunset was wearing. Specifically, the lack of pants. "I see you've made yourself at home already."

She merely scoffed at me. "Well duh! I may have spent the past decade as a human, but I'm still a pony deep down. I understand why humans prefer clothing, don't get me wrong, but I still prefer going au naturel whenever possible. Besides..." Sunset smirked as she eyed me up. "It looks like you joined the "no pants party", as Pinkie would say."

Well, she had me there.

As we lapsed into silence, Sunset turned back to her workstation. It was moments like this that solidified just how much I liked Sunset. She, more than any other pony, actually understood what I was going through. She knew what it felt like to be dropped into a completely unknown situation and not only adapted but thrived. It gave me hope that I could do the same. Although I wasn't planning on taking over the world with an army of teenagers in my case.

While Sunset was working I couldn't help but notice that she was acting funny. Every few moments she'd glance over at me and bite her lip before returning to her work. Looking closer, I could see her cheeks darkening as she slowly developed a blush. It wasn't until I could just barely make out a whimpering noise that I had to speak up. "Something wrong?"

Sunset jerked her head to the side and slapped her cheek before turning around to face me. "Nothing! Nothing's wrong!"

"You sure?" I asked. "It certainly looks like something's wrong with you."

Sunset bit her bottom lip. "Okay, honestly, you're kinda distracting me."

I blinked. That was unexpected. "How?"

She threw her arms up in surrender. "Have you not looked at a mirror? You are literally a perfect match for the ideal pony form right now. You went from tubby bastard to sex goddess practically overnight!! I'm surprised you're not drowning in mares right now! Seriously, it's taking all my wilpower not to just bend you over the table and rut you until you can't walk straight!"

It was at that point that I saw Sunset's cock poking out of her sheath. Something she said must've rubbed me the right way because I felt my own length waking up. The only thing keeping me from popping a full-on stiffy was the idea that Sunset wanted to be the pitcher. I don't know how far my internal changes have gone yet, but I was hesitant to... test it out. Especially with what was looking more and more like a lust crazed hermaphrodite.

I was saved when Twilight kicked the basement door open and glided down the stairs. She was carrying a metallic briefcase of some sort, but I had no clue as to what it contained. "How's everypony doing?" she asked cheerfully.

Sunset grunted and went back to work. I shook my head to try and get the lewd thoughts out, with little success. "Just catching up," I said. It was the truth, but not the whole truth. I think Pinochio'd be fine in my position. "What's with the luggage?"

Twilight didn't answer right away. Instead she trotted over to her own workbench and set the case down. She unlocked the clasp and flipped the lid open, stepping aside to allow me to look inside. I walked over, and saw that the interior was lined with foam. Inset amongst it like a firearm in a gun case was a single small, corked, bulbous glass bottle filled with a liquid blacker than pitch on a moonless night. Seriously, it looked like it was absorbing the light around it.

"Magical resonant imaging contrast dye," Twilight said, answering the unasked question. "It's a very expensive substance, hence the special transport case, but I'm going to need it if I'm going to properly track your internal changes."

Hesitantly, I reached over to pick up the bottle. When Twilight didn't stop me I grasped it by the neck and pulled it free. As I jostled the bottle the liquid inside flowed like it was ordinary water and not the sludgy substance I was expecting. "How expensive are we talking, here?"

"Trust me, you're better off not knowing," Twilight replied. "Let's just say that even with my status as Princess I had to call in a few favors to get my hands on this much."

I eyed the bottle questioningly. "Is it going to be enough?"

"Easily," Twilight assured me. "A little bit goes a long way. I just went overboard just in case. If we don't use it all it's got a practically indefinite shelf life."

"I see," I said. "So, what do we need to do?"

Twilight's horn glowed as the bottle in my hand flew out of it and a tiny spoon, no bigger than one you would use to feed a baby, appeared next to Twilight on the table. She carefully uncorked the bottle and dipped the spoon into the black liquid. After letting the excess drip back into the bottle. Twilight held the spoon out towards me. Hesitantly, I took the proffered utensil and put it in my mouth and gulped the black fluid down.

I was expecting it to taste nasty; like cough syrup mixed with raw sewage. I was pleasantly surprised when I found that it didn't taste that bad. Rather, it didn't taste like much at all. Like dry water, if that makes any sense at all. It did give off a pleasant tingle all the way down, though.

"Alright, now what?" I asked.

"I'm going to need you to take your shirt off and stand very still.," Twilight replied. I quickly stripped out of the only clothing I had on and complied with Twilight's request. "Good. Now spread your arms and legs a bit, please." I did so without question. Twilight's horn glowed for a moment before a similar glow surrounded my now-nude body.

The glow around my body cut off after only a few seconds, but Twilight's horn started to glow brighter and brighter with each passing second. Soon the tip of Twilight's horn was as bright as the sun before, with a blinding flash, she cast her spell. Appearing before us was, well, me. Okay, it wasn't me, but rather a hologram, one with the outside bits cut away to show the internal organs. Kinda like one of those models you would see in a doctor's office, only made of light and not plastic.

I didn't have the foggiest clue what Twilight was looking for, but she made several pleased 'hmm' noises as she visually ispected the image. "Yes, as I suspected, the internal changes have progressed at pace and are well on their way to completion," she said, more to herself than anything. "It looks like the upper respiratory and digestive systems have finished their transformation, explaining Starlight's report of Ben's lack of a gag reflex."

Alright, I definitely didn't like how Twilight was talking about me like I wasn't in the room, but she was too 'in the zone' for me to get her attention. I simply watched as Twilight leaned in for a more detailed observation.

"Subject's lungs look to have grown a little bit, increasing in capacity. Mammary glands appear to be fully functional though not actively producing at the moment. Stomach appears to be unchanged, although I wasn't expecting any at the macro level. Will have to perform further testing to get a more accurate assessment."

As she continued her inspection, Twilight blinked and began to frown. She had found something that threw her for a loop.

"Something wrong?" I finally spoke up.

"Not wrong, per se," she replied. "I'm not getting a good reading on your prostate. It's being blocked by something. What, I don't know." Twilight scratches her chin in thought for a moment, then sighs in resignation. Her horn glows and she summons a table from the aether. "I'm going to have to do this the old-fashioned way."

I barely suppressed a shudder as I recognized the table. It was a simple thing; waist high, square, metal, and padded. It was what Twilight had me lay on during some of her more... invasive procedures. When she mentioned the word 'prostate', I knew what she'd want me to do. As if to confirm my thoughts Twilight put on a pair of latex gloves and began to thoroughly lube up.

Resigned to yet another hit to my dignity, I approached the table and assumed the position; face down, ass out. Thankfully Twilight's examination table was designed for comfort. I laid as still as possible as I heard Twilight's hooves clopping against the tile floor, approaching me from behind.

"Could you move your tail aside, please?" she asked.

I had almost forgotten about that little wrinkle. Unfortunately I hadn't exactly mastered moving my new appendage quite yet. I concentrated hard, but only got a pathetic little flick for my trouble. As if sensing my trouble, Twilight simply grabbed my tail with her clean hand and held it to the side. My trepidation only grew as Twilight got even closer. I yelped as I felt her lubed fingers touch my pucker.

It wasn't quite a new feeling. Twilight had given my a rectal exam once or twice since my arrival, so I knew what to expect. What I didn't expect was the feeling that my nerves were turned up to eleven. I felt every ridge of my anus being rubbed as Twilight thoroughly lubed up my ring.

Then she stuck her finger in and I nearly blacked out. My vision went blurry and I hissed in a mixture of pleasure and pain, although the pain was swiftly subsiding. I clenched my hands tight against the table as I fought hard not to tighten my hole, lest I not let Twilight finish the job. My cock had escaped the confines of my sheath and was dangling below the table, blood flowing southwards rapidly hardening it.

I tried to keep myself under control. Really, I did. But Twilight's ministrations were turning me on something fierce.

Then she stuck a second finger in and I yet again nearly blacked out.

"Subject seems to be experiencing increased sensitivity," Twilight said in a clinical tone. I could only just make her out over the haze of pleasure. My cock was rock hard and dripping precum like a leaky faucet. Twilight seemed oblivious to my ordeal as she kept going deeper and deeper.

I let out a gasp as she finally reached my prostate. Back on Earth I had read that the prostate was the key to the most powerful orgasm a male can achieve. Now, with Twilight rubbing on mine like a crystal ball, I thought that the people who said that were downplaying just how intense it was. Within mere moments I was ready to paint the floor with a heavy load of cum.

But, to my dismay, Twilight pulled out with a wet *schlick* before I reached my peak. "Okay, Ben, your prostate appears normal; for a pony at least. You can get up now, if you want-"

Twilight was interrupted as I backed my ass into her and started rubbing her crotch. In my lust-drunk state, there was no way in hell I was about to let Twilight not finish me off.

"Ben, what's gotten into you?" Twilight asked desperately as I continued to grind into her crotch. I could feel her cock beginning to poke out.

"Isn't it obvious, Twi?" Sunset chimed in. "Whatever you did really turned him on. I don't think he's going to just let you go without getting him off."

I whimpered pitifully as I waited for Twilight to take action, fearing that she actually would leave me in this state. My worries proved to be false as Twilight grabbed hold of my ass and began to rub into me, her cock growing harder and harder as she hotdogged me.

"Well..." Twilight began in a husky tone of voice. "You are right, Sunset. It would not befit my role as a Princess to leave a friend in such a state. I must see to my subjects needs above my own, after all."

Sunset giggled. "Especially if serving your subjects just so happens to serve your needs as well."

Sunset then got up and sauntered over to us, massaging her semi-hard cock all the while. She stopped in front of my face, allowing me to smell the musky aroma wafting off her member. Unlike Starlight, Sunset Shimmer's cock was as thick as a normal pony's. I gulped as I imagined her ramming that thick rod down my throat.

Unbeknownst to me, while I was distracted with Sunset, Twilight took that oportunity to line her royal scepter up with my asshole. I felt her cockhead press insistently against my well-lubed hole. After a token resistance, she forced her way in.

Oh dear sweet Jesus, Buddha, and Kami; I nearly came the instant she penetrated me. I was expecting a bit of pain, but there was none to be found; only pleasure. She kept sliding in with almost no resistance and I could only moan in response. Then I felt the medial ring pop on in. "Fffuuuuuuuck!" I yelled, and Twilight kept going. When I felt her ring rub against my prostate, that's when I reached my peak. I moaned even louder and jets of cum shot out of my cock, painting the floor and underside of the table.

I continued to moan and cum, my peak seeming to last forever. I was silenced, however, when Sunset shoved her own marecock into my mouth. It was a tighter fit than Starlight's, but my jaw somehow stretched enough to where it was only mildly uncomfortable and not screaming in agony like I was expecting.

My cock continued to spew cum as Twilight thrust again and again, continuing to rub her ring over my prostate. I had read that prostate orgasms could last a while, but this was ridiculous. I didn't care at the time. My vision began to blur while Twilight continued to fuck my ass. Sunset, conversely, had not moved at all. She was allowing the momentum from Twilight's thrusts to force me further on her cock while I simply sucked and licked her wonderful rod.

With a couple more jets, my first orgasm finally petered out, but I felt another one rapidly approaching. Twilight was now jackhammering away at my ass, grunting and moaning all the while. Sunset's cock twitched in my mouth, and she grabbed the back of my head before she finally began facefucking me in earnest, her moans almost a counterpoint to Twilight's.

Twilight's moaning reached a crescendo before she at last hilted inside me. Her cock twitched and I could feel jets of cum blasting the inside of my ass. She leaned forward until her tits were pressed firmly against my back. She then reached around and pulled my torso up a foot or so.

Sunset, rather than cumming straight into my stomach, pulled out and began jerking herself off. It took only a few seconds before the first jet blasted me in the face. Luckily I had closed my eye in time so I wasn't blinded. The next one went higher and managed to get Twilight, who was looking over my shoulder. Her third rope went a little low and practically covered my tits in Sunset's creamy essence. The next two barely made it out of her cock, dripping pitifully onto the floor.

With Sunset finally done, I licked my lips to clear them of her seed. Oddly enough, they tasted like oranges. I reached up and cleared the spunk from around my eyes. And my forehead. My cheeks as well.

Twilight pulled back with some difficulty, my now-eager ass not allowing her to easily extricate herself from it. She let me go and I just flopped down, landing in a veritably puddle of Sunset's jizz. I was smiling anyways, feeling almost drunk on the pleasure, and a bit worn out as well. My eyes slowly fluttered closed, but I maintained conciousness for a little while. Just long enough for Twilight to suggest our next move.

"We're definitely going to need a bath after that."

I awakened some time later chest deep in warm water. As my eyes slowly fluttered open, I saw that we had relocated to Twilight's luxuriously appointed bathroom. Although calling it a mere bath would be a gross understatement. The tub was the size of a small swimming pool to start. Made of the same crystal as the rest of the castle and interwoven with fine gold filigree, it was just bordering on extravagant for the mare with otherwise simpler tastes in furniture.

Further assessment showed that I was sitting in Twilight's lap; her purple-coated arm running a sponge over my cum-stained body as my back pressed up against her breasts and I ground my ass into her crotch, letting out a pleased 'mmmnn' as I did so. Across from us, Sunset Shimmer was lounging in the tub as well, and it looked like she was getting forty winks like I was.

"Looks like somepony's finally awake," Twilight said quietly, not pausing in her cleaning.

"Mmmhmmm," I responded as Twilight rubbed the sponge over my tits. "How long was I out for?"

"Not long. Only about ten minutes or so. How're you feeling?" she asked.

Her question gave me pause. How did I feel? On the one hand, I had just gotten fucked up the ass, something most men would call either humiliating or degrading. On the other hand, it felt good. Really good. Like, 'best sex I ever had' good. I honestly had no idea how to answer her.

Twilight seemed to take my hesitance as an answer. "I guess some confusion is to be expected. This was your first time on the... receiving end, after all."

I just nodded. "That was much more intense than what I was expecting."

"Same here," Twilight mumbled under her breath. I still caught it though.

I turned to look at her out of the corner of my eye. "Meaning?"

"I don't know," Twilight admitted. "The sensitivity of your erogenous zones has gone up. That's to be expected, seeing as how ponies are generally more sensitive than humans. But a sensitivity increase on this scale could mean any number of things!"

It was at this point that I started to get worried. "Like what?" I asked, a hint of fear in my voice.

"Nothing bad," Twilight reassured me. "Honestly, it could be nothing. There's so little that I understand about what's happening to you that at this point I can only guess. Hopefully when Starlight gets back from Canterlot I can hit a breakthrough."

"Starlight's in Canterlot?" I asked.

"I sent her earlier today to pick up a few tomes on transformation magic from the Archives. She should be back in the morning; just in time for the announcement."

That statement piqued my curiosity. "What announcement?"

"It's about... well, you." Twilight said. "We can't just keep this a secret. You've become something of a fixture for this town; ponies are already asking about your whereabouts. So, tomorrow, we're going to have a town hall meeting and explain to the citizens of Ponyville what you're going through."

I blinked. "So... you're going to tell them everything?"

"Not quite," Twilight replied. "There's a couple things that Princess Celestia doesn't want to leak just yet."

"Namely, what I'm working on," Sunset chimed in, proving that she wasn't actually asleep. "Can't blame her, really. After all, I am the one ripping the space-time continuum a new one. That'd give anypony with a modicum of magical knowledge a conniption fit."

Gotta admit, she's right there. I mean, look at all the crazy theories about the LHC that popped up over the years. "So, what now?" I asked.

"As far as we're concerned, you're done for the day," Sunset answered. She then opened her eyes and shot me a sultry look as the tip of her penis broke the water's surface. "Unless, that is, you're up for round two."

It took me less than a second to conclude that I, indeed, was up for another round.

Author's Notes:

Well, now it's Purple Smart's turn to get it on with our illustrious hero. And she brought a friend too. What luck.

Those of you who read the comments will know that I've gone on record that Ben will not be turning into an Alicorn. Well, it turns out, I might have lied about that. Keyword; might. Nothing is set in stone, but it looks like this story could go that direction.

The idea only really took hold a couple days ago, but I could see some interesting scenarios play out if I go that direction. But still, like I said, it wasn't the original plan, and it still might not happen, but it could.
