The next day I was woken up before I even had a chance for breakfast. At least my treats had gone over well. I fondly remembered the few who said thanks on my way back that evening. Emma promised that Japanese ponies were a reserved bunch, so if a few said thanks, that meant a lot more of them were happy about it, and just felt shy about coming over and saying it.

The three leading me didn't look like doctors. They were more like the mean guys that were outside, and they had those weapons with them. I tried to keep in line with them the whole time, which only made one of them smirk. "Smart. Stay in line and cooperate and nobody has to get hurt today." Geeze, someone should make them some cupcakes once in a while and remind them life has sweet things in it too.

They led me to a dim room and opened the door before one of them pointed inside with his weapon. Did they want me to go inside?

One of them grunted. "In." Okay! I bounced past them into the room. It wasn't very large, maybe ten feet across, with a mirror set up on one side of the room. I squinted at the mirror. Was that another room? I could just barely see it. "Now be a good horse." They closed and locked the door behind me and left me in the dim room.

I had a seat and looked around the room. It had lights in it, they just weren't turned up for some reason, making the whole place gloomy. Why would they want to hang out in the dark, or want me the hang out in the dark? The whole thing was confusing. The noise of the door being opened drew my attention. A doctor stood there, and he had a human stallion with him dressed in barely anything, just some kinda thin robe that didn't even cover his back end. Something about it made me think hospitals. Oh yeah! Rainbow Dash wore something like that once when she broke her wing. Was he hurt?

The doctor frowned. "Who set the lights so low?" He fiddled with something and quickly fixed that, bathing the room in light and forcing me to squint a moment before my eyes adjusted. The mirror was just a mirror. I couldn't see a hint of the room beyond anymore. "Miss Pie, we'd like to conduct a little experiment with you today. This man has volunteered to become infected, but we want to do it in a controlled fashion. Can you infect him and allow it to progress normally until we prompt you to continue?"

I perked my ears and felt my heart start to pick up. I could turn him into a pony? After all that time spent resisting it, the idea of being allowed to just do it sounded great! I was so excited! "I can do that!" I licked over my lips as I studied the human stallion over more closely. "What if I get a little... carried away?"

The doctor pulled out a collar and gave it a gentle lob so it landed in front of me. "Put that on." I looked it over a moment before slipping it around my neck. "If need be, we can give you a little jolt, but you've been very cooperative, so we shouldn't need it. We'll tell you when to begin, alright?" I bobbed my head and he gestured inside. The man stepped inside and the door was shut. I heard it being locked, but not much else from outside. The room must have been soundproofed.

That left me and my new friend, so I decided the right thing to do was to introduce myself. "Hi there, I'm Pie Pinkie. What's your name?"

He nodded at me, but he wasn't smiling. "Nice to meet you. I won't be a good fit for my name for long..."

I tilted my head. "Japanese names are pretty sounding to me. They'd work just fine as a pony name. Why are you so tense?"

"Why shouldn't I be?" He rubbed his arms nervously. "You're going to turn me into a horse, or pony."

I nodded. "That's what they said, but didn't you ask for it?"

He smiled then, but it wasn't a happy smile. "It was that, or be dead, and I wasn't brave enough to take the second option."

I opened my mouth to ask more as a voice came in over a hidden speaker, "Go ahead and begin, Miss Pie. Expose him, then let him proceed naturally to begin."

I nodded towards it, eager to begin, but also burning with curiosity. I didn't want to hurt him, even if... I stepped towards him at a sedate trot. "Why would you die?"

He glanced away. "I snuck in here, they caught me. They were ready to kill me, but they had another idea, so here we are. Go ahead. Will it hurt?"

I thought back to the other times I saw a human become a pony. "Yes," I answered truthfully. "I'll be here to help. You won't be alone. I don't think you're that bad." He relaxed a little, and slid to the ground, which made it easier for me to press in for a nuzzle, rubbing my lips against his. "A little kiss to get started." He was reluctant, but he didn't fight when I gently pressed my lips to his. He jumped when my tongue pushed forward, but it was already too late by the time he tried to pull back. His mouth tasted of some curious herbs. I sat down beside him instead of in front of him. "Now we wait." I already felt better about being around him. Whatever was happening had begun, but would it take days like Emma or Aiko?

A slot on the door slid open. "Put your arm through and let us get a sample. We'd prefer a constant drip, but physical activity could shake it loose. We'll take what we can get." The man offered his arm and winced a moment before pulling it back. "You're both doing excellently."

I nestled in with the man and he seemed to relax against me. He was becoming calmer over time, but also a little excited down below. I think... I think he wanted a private party. I nuzzled at his chest and down to his belly, but didn't stray much closer. We weren't told to play again, yet. He squirmed against my attention and panted a little, but was mostly quiet.

It felt like forever before the voice came back. "Alright, let's get one more draw, then another exposure." After he put his arm through the slot, we were allowed to continue, and I had more in mind than just a kiss, even if kisses were fun. I brushed my hooves over his front, trapping his excited member between them and slowly rubbing along them as I looked into his dark eyes.

"W-we shouldn't," he gasped out, but he didn't try to get away from me. He was shy. They were all so shy about these things. I nuzzled into the human cock I held, feeling it pulse and jump beyond the thin cloth that kept it away from me.

"Go ahead and take off your robe," suggested the voice. Good idea! I reached to help him, but he swatted me away.

"Let me do this myself." He pushed to his feet and looked down at me with some concern, but he pulled off that robe. It barely tried to stay on him. As it pooled around his ankles, his shaft sprang into view, jumping in front of me in little twitches. It looked delicious. I opened my mouth and leaned forward, but he ducked to the side, avoiding me. "Do we have to?"

I pouted a little. We were playing. I didn't want to make him sad. "You're already changing, this way makes it faster. Let's do it, as friends." I moved in and nuzzled at his leg, slowly rubbing my nose along it, getting closer and closer to his groin as I gave the littlest nips. "Only if you let me. I'm not here to hurt you." He was starting to ease up, and when I went for it, he didn't run again. I was rewarded for my patience by getting his pole. I gently nursed at the head of it. Human cocks were shaped differently than pony ones. Not badly, just differently, and I suckled gently at that mushroom-like head as I reached up and rubbed over his balls with my warm hooves. He sank back against the wall and began to breath heavily as I took him in a few more inches, enjoying my lollipop.

"That's enough," said the loud speaker, and I felt really angry. We were just getting familiar and... grrr. Oh well. I pulled back from him and nuzzled the end of him, watching it pulse and throb, and get a little bigger? Yes, with each heartbeat, he was getting the littlest bigger in front of me, and I watched with fascination as he began to slowly grow a new cock. His balls suddenly pushed outwards, stretching their container as they grew about half again as larger, one of them hung lower than the other. The human groaned and sank to his bottom against the corner of the room. "Miss Pie, could you step away a moment?"

Did I have to? I reluctantly obeyed, wondering if they were getting the notes they wanted to have. "Fascinating. Pinkie, have you noticed a correlation to the sight of continued infection and progress?"

I didn't understand that exactly, but I remembered the other time. "I think so."

"Let's test it. Would you attempt to give him a tail?"

Tail? Well. I closed with him and gently nuzzled his side. "This will hurt a little, but remember, I'll be here for you, with you, alright?" I nudged my way between him and the wall and gave his bottom a little sniff. He didn't smell like much of a pony, yet. They wanted me to be super specific, so I pressed with my hooves and found the spot where a tail should come out if humans weren't so oddly shaped. Each little touch seemed to make him squirm. He was all hard and ready. If we didn't have to do this a specific way, I was certain he'd rather be riding the Pinkie Express than having me nosing around his bottom. I flicked out my tongue and explored his bottom, tasting the sweat of his exertion, a little fear, and building excitement. I could taste it all as he grunted. He arched his back and suddenly went quiet. I gave another slow lick and felt it moving under me. The bones were shuffling and he was resisting crying out. "It's alright to cry if you need to," I spoke to him gently as I nuzzled the forming nub, then took it into my snout, suckling at his quickly developing tail as it grew into me quickly. Whatever little tail bones humans had were expanding into my mouth, quickly growing too large for me to hold them all. I couldn't swallow a whole pony's tail! So I drew back and nursed at the last six inches as it grew and grew.

"Enough." Aw geeze! I slid back away from my new friend and stuck out my tongue at the mirror. "Thank you, Miss Pie. You're doing very well. Let's get another draw, if you're feeling up for it?"

The man gave a shuddering nod, and offered his arm through the slot, but his eyes were on me. "Will I be a dumb animal?"

Dumb animal? "Am I a 'dumb animal'? You'll still be you, just a pony. It's not that bad, is it?"

He chuckled softly. "You wouldn't be so easy about it if you were being made into a human, perhaps."

Would I be? I'd had fingers before, and stood upright before, and wore clothes before. See, I already had most of the human experience! All I needed was a good shave. "Are you feeling alright?"

He settled back down and scratched at his lower back awkwardly. "It itches a lot. Am I getting fur?"

I peeked around him and saw his tail growing a thick layer of black fur. Black seemed as common in Japanese ponies for fur as it was for their manes as humans. The glossy black tail hair on black fur was quite a sight. It was so... So bland compared to most of the bright colors of my pony friends, but it wasn't a bad look. It was kind of nice in its own way. "Yep, all black." Looking back around him, I saw the fur was creeping out around his groin, and he was quickly developing a sheath to hold his new cock in, though it wasn't in the mood to hide.

He gave a groan as loud pops began to come from his back, traveling up from his new tail. He fell forward and curled in place, looking so miserable. I nudged into him and wrapped my legs around him. We didn't kiss or play, I just held him tight. "It's gonna be alright," I whispered to him as I squeezed. We were getting to the hardest part and I refused to let him be alone for that. Despite the pain of it, he was still poking me in the belly. I rubbed back against it a little, wanting to do more, but he needed me to help him, not play with him, yet.

"Miss Pie, you're obstructing the view."

I gave a big-time frown at that. "He's hurt and he needs a hug right now. Leave us alone."

"Miss Pie, please. We want to observe as much of this as possible. You can hug him afterwards."

I pulled back a little and slid up to my hooves. I circled away from the mirror and nuzzled into him on the opposite side. "I'm here for you." He didn't make any noises that made sense besides saying 'Ow this kinda hurts.', but that message I got loud and clear. He clenched his hands a moment, then spread them out as hooves started to grow around them, sealing his fingers out wide as his palm grew forward into frogs. I pressed my hoof against his new ones and gently rubbed our frogs together. It felt nice to just press our palms together like that. "You're getting through the hard parts."

He suddenly rose up, trying to stand, but doing a really bad job of it. He was stuck between pony and human. Hunched over, he grabbed for me and pulled me close. "Is it almost over?"

I nuzzled into his chest even as it became more and more round by the moment. "You're doing good, promise." I was going to say more, but he pushed me to the ground, and decided it was time to start the party. His new flat head pushed between my legs and I pushed back, inviting him inside. They didn't try to separate us again, thank Celestia.

He slid into me with one long push, sinking into his new medial ring. I swayed my tail up under myself and tickled over his hanging balls, more than enough encouragement to get him to draw back and slam into me. He was a little rough, but I didn't mind rough stallions, and he was far from the strongest I'd ever been with. We began to buck and dance together as I grew sopping wet, making each movement nice and smooth. I tightened around him when he was deepest with each push, milking him a little with every shuddering slam of our bodies. I could see his tail was lifted and swaying excitedly, and his feet had become hooves, but he was still standing up in that odd way. The feeling of change against me had died away, but he never became entirely pony, just mostly. He grabbed my flanks with his hooves, holding me up and squeezing as he rocked faster and faster. There wasn't any more pain, just pleasure for both of us as we bumped and grinded together. His medial ring ribbed over my vulva with every thrust, driving me wild as I crashed into the second climax of the time. There was one thing human stallions had, and that was endurance. He seemed to want to rut me forever, and that felt just fine by me.

I leaned up and nuzzled for his face and noticed he never developed a proper muzzle. He was a human-faced pony, which was kinda odd, but I wasn't in the mood to think about it much. I mashed my lips against his and our tongues met. I tilted my head so we could get a better fit and we writhed together in bliss. I felt the head of him swell inside of me and lock us together, then the powerful jets of hot fluid began to fire, filling me up with his homemade foal batter as we muffledly cried out to each other. He suddenly rolled over and pressed me to the wall as he pulled back, popping free of the seal to start rutting me anew. This stallion had no limits!

I could hear the loudspeaker say something, but I couldn't focus much on that while I was being given the rutting of a lifetime. He kept me bouncing up and down along his new pony pecker and I didn't care about anything else in the world. I felt a painful jolt run through me and cried out with annoyance and ouchiness, then it happened again.

"Miss Pinkie." Ok, I heard that. I perked an ear and looked towards the camera. "Very good. We thought we lost both of you. Can you please rouse your partner?"

Rouse him? He was still pistoning into me. I was pretty sure that was as roused as a stallion could get! I nipped at the new pony's throat gently. "Hey. Come on. There's more to life than this you know."

He squeezed me in a soft hug and slowed, but he kept himself plunged into me, his medial ring popped past my swollen vulva. I was feeling tender, but kinda good. "I'm here," he said softly, hugging tightly a moment. "Am I a beast now?"

I nipped at his shoulder. "Stop saying that. You're a pony, but that isn't a beast."

He chuckled softly. "You would say that... Am I your mate now?"

Oh gosh! "Um, we're friends. Maybe we could play again another time? But we just met. Even I know you have to be closer before you say someone's your special somepony."

"We'd like to ask you both some questions, please move to the side of the room."

He stood up and took me right along with him. Was he planning on staying attached to me all day? I mean that was kinda interesting to consider, but I was used to stallions getting tired after a while and then we'd do other things. A party with only one game got old after a while. I ran one of my hind legs up over one of his and smiled up at him. "You can put me down now, please."

He looked embarrassed a moment as he drew from me with a wet sucking sound. His stallion butter began leaking from me as he set me on my hooves, but I wasn't angry at him. I hopped up to my hind hooves and showed him with a big smooch. "You'll probably be staying with us in the pony wing, so we'll get to meet again. Don't be sad." It was then that I noticed, again, that he never got a pony face. His human face looked so odd on his otherwise mostly-pony body. It hadn't even grown fur, and it didn't look like it planned on going ahead with it. I didn't even know that was an option! "You feel alright?"

The door was unlocked from the outside, and the doctors were there. They offered a towel to wrap up the new pony and led him away. They offered one to me, and I used it to towel off, but I didn't need clothes. The doctors seemed a bit embarrassed around me for some reason, but led me away towards the nice Doctor Rina's office. Before they left, I smiled up at them. "Is he going to be alright? They're not angry at him for sneaking in anymore, right?"

They looked more uncomfortable. "He did his part. We'll be pushing for him to be released into the pony wing."

That didn't sound like a sure thing. "What happens if they don't put him there?"

One looked towards the other. They knew something... "Please?"

He pinched the bridge of his nose. "It's up to the military. If they want, they can still kill him for sneaking in here."

I gasped at that. "Why would they?! They said he had to be a pony, and he did that. Now they're even, right?"

"We'll do our best, promise, but it's not up to us." They left in a hurry, and I turned back to Rina's door. I knocked twice and a familiar voice beckoned me inwards.

There was Rina, sitting in her comfy chair. She smiled at me. "I heard you had quite the experience today."

I hopped up onto the sofa and settled down. "You know about it all? Are they really gonna hurt him? He didn't even do anything that bad!"

She leaned forward, hands clasped. "He knew it was illegal before he did it, but we're not here to discuss him. I'm more interested in how you feel after that. I was told you were permitted to infect someone all the way?"

I nodded a little. "Well, mostly. They didn't change all the way. They were eight out of ten parts pony." I sat back and frowned. "He didn't even tell me his name..."

"We have a few questions, about what you told us yesterday. By what means do you propose you traveled through time?"

I tilted my head at that. Even I didn't really know how that worked. "My friends did it. I was along for the ride. They went through the space where the pony energy came from, and the other stuff, and it's as much a 'when' as a 'where', so I hopped out in time to catch the blast."

She nodded as she made those little scribbles. I bet I wouldn't be allowed to look at them again. "You understand how outlandish your story sounds, do you not? How can we verify it?"

I squinted a little, thinking about that. "If we could find a princess, that'd prove something, right? We really should!"

She gave a little smile. "And how exactly would you go about doing that?"

Good question! "Well, if we're lucky we already have one. I'd ask around the ponies for who they think are the best leaders, not because of anything they did, just who feels like the easiest to follow, then I'd keep an eye on those ponies and they may turn up. If they're outside, you'd look for a bunch of ponies gathering around a pony. Basically, follow the leader!"

She lifted a pen at me. "Many ponies say you feel like a natural leader."

Oh gosh! "Aw, that's nice of them to say, but that's just because I'm being nice. I'm not the only one they say that about, am I?"

She shook her head. "We'll investigate further, believe me, but for now, put the patient out of your mind. He'll either turn up in your wing with the others, or not."

Or not?! I wasn't the sharpest tool in the barn, as Applejack would say, but even I knew what that meant. "Isn't there something we can do for him? He isn't a bad guy, he shouldn't be punished anymore."

"I can list your formal support." She leaned forward. "If I may be frank, it may do him more harm than good. If they think they can 'teach you a lesson', they may hurt him just to lash out at you."

I sat up with wide eyes. "Why would they do that! I didn't do anything to them. I don't want anypony to be hurt. Nopony should want somepony hurt like that."

She gave a sad little smile. "We live in interesting times. Now, tell me more about your home..."
