I headed for the door and took a peek out both ways. The sky was turning red with late afternoon. We'd have to hurry, but it wasn't that far from what I remembered.

"Give me a moment." Hiro fished out a device from where his pants had fallen and struggled with it between his hoof-claws before he got it turned on. "This is Sasaki Hiro, we need a replacement down at the clinic. Can you send another man?"

"That's a negative. Just about everyone's busy with what they got. This is no time for vacation. Stay where you are." The voice came out of the thing he held, a little tinny but clear. It was like using cans with string, but better.

Hiro sighed gently before pressing the button. "Unfortunately I must refuse. The doctors don't want my service anymore. I'm contaminated with whatever this disease is."

"Shit." Well, that reply was direct. "Are you alright, Officer Sasaki?"

"That's affirmative. I have a new group I intend to protect, including an original horse. We'll be checking into city hospital, likely tomorrow. Travel is slow, but I feel confident we'll make it without incident."

"You're a lot more coherent than most of the boys I've had to talk to in your situation. Look, you're a plague carrier now. Don't go anywhere they don't want you to be, but take care of yourself. We don't forget our own. Boys upstairs are trying to get a quarantine area set up for officers fallen in battle if you need it. Keep your radio on you, don't hesitate to call if you have news."

Hiro grabbed the belt off his pants and slung it around himself before clipping the radio and a few other supplies to it. "At least they're keeping their head, and I wasn't fired on the spot." He smiled at us with a mixture of emotions. "I'm... I'm proud, of my country. They're not throwing me aside, I don't plan to do that to them, either." He focused on me. "Pinkie? Ready to go?"

I raised a hoof. "Ready!"

"Ready," echoed Emma.

Aiko took a few uncertain steps towards the door. "As ready as I can be. This body is so strange."

I was going to say it wasn't that odd, but she was one of those super slender unicorns that everypony seemed to think was really pretty. I always thought those were kind of weird. I moved up beside her. "You can lean on me if you have to." She hesitated a moment before letting some of her weight rest against me. "I guess I should... relax around my horse husband."

Emma suddenly blushed. "W-what? Who said Pinkie is your husband?"

I gave a nervous bit of a giggle. It was hard to argue being her, uh, horse husband or not considering how we'd just played. "I can sort of see that, but being a special somepony is more than just a special time together. We have to trust each other, with everything, and love each other. Do you love me?"

Emma blurted, "Yes!" Aw, she was blushing badly.

Aiko glanced at Emma and shrank against me. "I... I need to get used to this. I don't feel as opposed to the idea as I was before."

Emma wanted to be my special somepony, and Aiko was still exploring the idea of it. Oh, gosh, was I going to have a herd? I never thought I'd get one of those! Wait... "Hiro?"

He perked an ear at me. "Yes, Miss Pie?"

I waved a hoof. "Just Pinkie's fine, but how do you feel about this?"

He chuckled softly. "You are the center of our very unusual family. I don't know if you're even interested in that kind of thing, but I feel like it'd be fine."

'That kind of thing?' I frowned with thought before it clicked inside of me. "Oh! Wow, you've only seen me act like a stallion. I was born a mare. I like things as a mare." I turned from him towards the door. "We probably should go."

I reared up and grabbed the handle of the door. "We're heading out! Be sure to lock the door behind us!" With a big pull, the smells of the city rushed in. There was some burning, some cooking, and just general city smells. We emerged from the clinic out into it and Aiko rushed ahead, showing the way towards her apartment with increasing confidence in her steps. We made it about a block before the pavement in front of us suddenly sank in. From the rubble formed, a head popped free.

The pony smiled at us, then emerged, squat and earth pony-like, with a long neck that seemed to work good for looking out while digging. I tilted my head for a better look, mare. The mare climbed out towards us with that big smile, and said nothing. Hiro stepped ahead of us, watching the pony warily. "Stop right there. What do you want?"

The tunneler looked confused at Hiro's words, then sniffed the air a moment before looking directly at me. She let out an excited squeal and several ponies rushed out of alleyways and out from under cars, converging on our herd quickly. They scrambled up to us, up to me specifically, and began to crowd around. They didn't try to attack like the quasi ponies did, but then, these ponies were all ponies. An earth pony, one with long tongues it liked to wrap around everything, the tunneler, and a pegasus were practically feeling me up. It was flattering, sort of.

Aiko backed away nervously. "Are they hurting you, Pinkie?"

Her words drew the attention of another pony that emerged from the dark of a storefront. This one was a pegasus stallion that flew at Aiko and started sniffing at her, then bowed in front of her, his rump in the air, and face in the pavement. His act drew several of them away, except the tongue pony, who decided he wanted to play with me, and I mean really play! She wrapped her wet tongues around my semi-hard stallionhood and began slathering over it. "H-hey there!" I mean, that felt good, like really good, but we hadn't even been introduced yet. She flashed her weird teeth at me. Her mouth opened up three ways!

Hiro suddenly shoved back the tonguey pony. "Give us room. We need to keep going." He swatted aside another pony, getting his way over to Aiko and rescuing her from the crowd that seemed intent on praising her wordlessly.

Aiko took a quick breath as she was set down closer to the rest of us, looking a lot less freaked out. "Go away, shoo shoo!" Her words seemed to reach them and they took half a step back while peering at Aiko like they really wanted to come closer. "Shoo! Go away!" They backed away from us, but didn't leave out sight. They watched us, and as we walked forward, they followed behind about twenty feet or so. They weren't really that bad...

They weren't the only ones. While the ponies seemed content to stare at us from a distance, a block later had some quasi ponies, still caught between human and pony. They quickly took notice of our group, including the full ponies, and one of them pointed with a hand that was mostly a hoof. "There! If we can defeat them, we can be human again!" They all looked up with wild hope in their eyes and began approaching with bats and planks and anything else they could find to use as a weapon.

Emma threw up her hands. "Don't be stupid!" That didn't convince them though.

I edged away a little. "I don't think we want to fight with these guys." There were at least half a doz--Nevermind. Other quasi-humans spilled out of buildings around us, their expressions running the gamut of expressions, from shrewd and calculating to wild-eyed and entirely lost. The ponies behind us suddenly charged forward, which only prompted the quasi-ponies to charge, which put us right in the center!

Hiro grabbed Emma by the scruff and dashed off with her, which left me with the job of rescuing Aiko. I grabbed her around the middle, hefted her up and booked it. Looking over my shoulders, I could see the fighting was terrible. Ponies were smashed across the sides and snouts with blunt instruments or just punched or swatted, while the ponies seemed much more focused on being friendly in a not-exactly-friendly way. They'd grab a quasi-pony and kiss them, sometimes turning them more pony, and sometimes they'd get bit for their trouble, with blood running down their chins from their abused tongues. The stallions would try to mount anything that'd stay still, and the mares would sometimes offer themselves, and sometimes they'd be taken up on it. It was a big, confusing, mess, with injuries and 'special parties' all over the place.

Some of the changes happened super fast, with a mostly-human falling for the charms of a mare and becoming a mare himself quickly as he rode her. He, then a she, fell to all fours and gladly joined the ponies in trying to spread the pony disease, only to catch a 2 by 4 across the snout and crash to the ground, bleeding. It was awful, and I didn't want to be there for any of that. We left the crowd behind, brawling wildly. Thankfully, they seemed way distracted about us, and didn't follow us as we came up on Aiko's apartment. She had to say the combination as Emma pushed the buttons, but we got inside quickly.

As soon as we closed the door to the outside, a voice called out behind one of the doors in the hallway, "Are you one of the horses?"

I glanced at the others. "Uh, yes, but we're not here to make trouble, promise!"

"Kindly forgive me for not opening my door," called out the masculine voice. "The building's kept its peace. Don't ruin that."

We clip-clopped past him quietly only for the door two down to open gently. A female human looked out at us. She smiled a little. "So... did they find a cure?"

Aiko shook her head. "Afraid not. They're just figuring out what is--"

"Aiko? Is that you?" The woman looked at Aiko with surprise.

Aiko took a half-step back. "What used to be, yes. Am I hideous?"

She frowned a little. "You are elegant and... compared to what else I've seen, no, not by far. Are you sane?"

Aiko smiled a little. "As sane as I can be."

Emma offered a furry hand. "We're all in one piece, physically and otherwise. Are you alright?"

She shrugged softly. "The power's out, monsters are wandering the streets. Everything's falling apart so quickly. No, no I'm not alright... If I have to be a horse, can I be a slender one like you, Aiko?"

Aiko squirmed. "I should be appalled, but the more you talk about it, the more I want to say yes."

Hiro didn't say anything, but I had a feeling he agreed, or he would have said something. Making her a pony felt like a natural thing to do. "All you have to do, if you're sure, is be friendly with us. Kissing, breeding, that kind of thing." I flashed a smile at her. "You really should be sure though. It's one way as far as we know."

Her eyes wandered to my stallionhood, then towards Hiro's, but she moved right back to Aiko. "I want to be like Aiko."

Aiko flushed deeply. "I'm a woman, and so are you."

She rolled her eyes. "You're not that sheltered. Two woman can do things. I've seen a few of the videos you've 'snuck' in."

Aiko's blush worsened. "H-hey! Stop spying on me!"

Emma giggled manically. "I didn't think you had it in you, Aiko."

Aiko stomped at the ground. "Not you too! A girl's allowed to be curious in her own home."

The girl crouched in front of Aiko and gently pet over Aiko's mane and gave a light caress over Aiko's new horn, making her shudder powerfully. Poor Aiko, unicorn horns were very sensitive.

Aiko glanced past her friend. "Chie... why don't we go inside?" They walked into Chie's apartment and the door closed behind them. A bit of me felt jealous. Aiko was mine! And I wanted her friend too! But that wasn't really very friendly, and I fought off those bad feelings. "Let's get to Homer and relax until morning."

We climbed the stairs, with the elevator not working in the dark city. Homer was right where we left him, and he hopped to his feet with a waggy tail at seeing us. "Hello!" He looked around quickly. "Need to go!" Aw, poor guy waited so long. I pointed the others inside, and Emma went with Hiro towards the kitchen.

I led Homer outside and we started back down the stairs. "You wouldn't believe all we've seen today."

"I saw some of it," he said, nuzzling at my cutie mark. "Angry people. Bad smells. Bad things are going on. This place not safe?"

I led him outside, but not past the gate, and he quickly scurried behind a bush and took care of business before emerging, looking satisfied. "Not safe?" he repeated with a tilt of his head.

"Don't worry." I patted him gently over the head. "We're leaving tomorrow, all of us, you included. We're not leaving you behind again."

As we walked back along the hallway, we heard a rather loud moan come from Chie's room. I blushed at imagining what they were up to, and I felt a powerful urge to peek. One little look couldn't hurt... I reached for the handle and gave it a slow turn. They hadn't locked it in their hurry, and I got my peek.

Chiee was behind Aiko and rutting her like the stallion Chie was rapidly becoming. Every heavy slap of their bodies spread more fur over his body as his balls swelled with the hammering of his heart. He was breeding her, and she was happily accepting him, and the two were lost in the pleasure of their motions with louder and louder noises coming from both of them. He gasped as a horn pushed free, and he began to become a unicorn. At least it's what he wanted, even if he probably had a mare in mind. She was a he, and a well-equipped he. He seemed to love plunging his horse cock in and out of his lover, with his new balls slapping up against her pony butt as he became more and more pony with every motion against her. He was becoming a pony stallion, and neither of them had a complaint about it.

"What are you looking at?" asked Homer as he tried to poke his head right in past me to see. I quickly pushed him back and closed the door perhaps a little hurriedly. I hoped they were too busy rutting to notice anything.

"Nothing! Just two ponies getting to know each other."

Homer leaned in and sniffed at my groin. "Why haven't we gotten to know each other?"

I turned pink, er, more pink, quickly. Did Homer really just ask that? "I didn't know you liked that kind of thing, and that's for two ponies."

Homer perked an ear. "She wasn't a pony, now they are." He smiled. "Why not me?"

Why not him... I didn't have any really good reasons. I gently pet over his ears. "Are you... sure?"

Homer bobbed his head. "I came to be with you. I want to be with you, all the way with you."

I gestured for him to follow me and we started trotting to the stairwell. As I climbed up, I felt his eyes on my rump, watching my tail sway with each step. Before we got up two stories, he hopped up on me and nipped at the back of my neck. "I'll be good."

Good would be waiting for me to give the all clear signal before jumping on me! I wriggled and snorted like I was annoyed more than violated. Oh, who was I kidding? After watching Aiko and Chie go at it, I wanted some special time with someone, and Homer was as good a play partner as anypony else, even if he wasn't technically a pony. He could tell I wasn't saying no, and he wrapped his forepaws around me and hugged tightly a moment. "I love you, Pinkie."

Aw. "I l--Eee!" I shrieked as he found the mark and pushed into me. The end wasn't flared like a pony at all. It was narrow and slipped into me easily. He started to piston with quick short motions a lot faster than I was used to, but it felt kinda... kinda really good. I panted and pawed at the ground as he rutted against me. "Homer..." His slobbery tongue ran over my ears, licking over them between each of his quick pushes. His form on top of me seemed to be changing subtly, and his shaft widened bit by bit. Was he going to gain a nice big fat horse cock? I kinda hoped he would. I wanted a big stallion cock right then. I arched my back and invited him inside as he worked harder and harder, and I started to feel something new.

He was swelling, and not the little swelling a stallion does, oh no. He was blowing up like a balloon, and each pull back it'd tug at my thick vulva, then he'd ram in past it, each time a little bigger. It was painful, but exciting, and it sent flashes in front of my eyes. I wanted him to stop. I wanted him to go, I just didn't want him to ever go away! He rammed in one last time and couldn't get back out, but not for lack of trying. He started to rock spastically in the little space he had before the member lifted inside of me and began to fire thick volleys of creamy dog-pony seed into me. I wrapped my tail back around him and held him close as he howled with pleasure and I joined in, probably scaring a few people as we filled the stair well with our pack howling, like a bunch of horny wolves.

It was over, and he held me closely and lovingly. His paw roamed over my belly from behind and even teased over my still rock-hard member. "Thank you."

I threw a leg over him and flopped over, facing him, and saw what happened to him. He was a doggypony! He had his paws and cute drooly tongue, but he had the sharp eyes of a pony, and the same size and shape too. His cock felt like a hybrid, with a doggy's knot holding us together, but the tip flared out into me. He was a dog pony, and he was ours. I kissed him gently across the lips. "Are you alright?" He nodded quickly and I kissed him again. I could think of far worse things.

When he softened enough for me to pop free of him, I rose up to my hind legs. To my surprise, he followed me, and followed me up the stairs, wobbling, but looking proud to be walking that way. I kept a hoof at his back. Imagine if he fell trying to look cool for me? I'd feel awful, so instead I walked alongside him and helped keep him upright the whole way. When we reached the right floor, we both went to all fours and trotted out towards Aiko's apartment.

As we reached it, I wondered if Hiro had fallen for the same urges Aiko and I had surrendered too and was doing things with Emma. I held up a hoof and went 'shh' at Homer before sliding open the door and peeking inside. Hiro was curled around Emma, and both were asleep. They didn't look or smell like they had done anything more than just cuddle and be friends. Aw... They were adorable. I waved Homer in and guided him to curl up with me close to Hiro, and soon we caught some sleep as well.

We were woken up not that long later as Aiko clumsily stepped inside and looked around. She turned and closed the door with a shove of a hoof, wincing at the bang it made. "Sorry," she whispered, then began creeping towards her room. She smelled clean. Did they bathe or shower before she came back up here?

Hiro perked up from where he was resting. "Is everything alright?"

"E-everything's j-just fine!" squeaked out Aiko with obvious embarrassment. She hung her head a little. "I'm just a wild animal, following my every impulse..." She dashed off into her room and banged one more door before quiet returned to the apartment.

We managed to find sleep. With us all woken up like that, we ended up all curled up together, minus Aiko. Emma became curious, and pet over Homer. "You look cute as hell. What are you now?"

Homer tilted his head. "A part of this pack." He leaned in and nipped at one of her blue ears. "You smell like a beta male. I will treat well, like a brother. We're a good family."

I perked an ear with curiosity. I remembered what happened to Aiko's friend. "Are you saying Emma's going to be a stallion?"

Emma gasped with surprise. "Why? I'm fine the way I am."

Homer shrugged. "It's what I smell." He sniffed at her softly. "Means you can be with Aiko."

Emma began to burn at that. "Pinkie, why can't I be like you?"

Like me? I glanced down at my he-she nature. I didn't know how I got that, or how to share it. "Best I could offer is to spend some time, and either you 'catch' it or not. You're part of our herd either way."

She slid off of Hiro and right against me. She pressed against my belly and her hands rest on my cutie mark. "I don't want to stop being a woman. I'm alright with being a pony, but don't let me turn into a guy."

Hiro raised a brow from where he lay. "Being a man isn't that awful. You're saying it like it's more of a curse than being pushed onto all fours."

I wrapped my hooves around Emma and nibbled at her blue ears. "Like Hiro said, it isn't the end if you did become a stallion. All I can do is, uh, do things, or not do things."

She threw a leg over me and directed my still hard member up against her petals. "Than it's time to do things, and hope that'e enough to get me on a better track. Besides, I've been waiting for you to ask for days, did you lose interest?"

"No!" I hotly denied, then rolled over on her. If she wanted some Pinkie time, I would deliver it. I rode her wildly even as I felt her changing beneath me. She was becoming a pony, one with leathery wings that sprouted from her back. She was a bat pony, and a well-built one at that. She tried to seal up, to push me out, but I didn't let it. I pushed against her rebelling body and kept right on rutting her. She thrashed and cried out with every push at that point, trembling with emotional overflow from being filled past capacity and being ridden while her body tried to divest itself of her marehood, but I promised her, so I didn't let it.

The pushing sensation slowly dwindled and died, though the rest of her changed. She became a stallion with a marehood, one well filled and worked by me. When I finally withdrew from her, she didn't change. She was done, as a very masculine female. Emma flopped over, panting from all the workout we both had. "T-thank you, Pinkie... Thank you."

Author's Notes:

Welcome to the herd properly, Homer.

The only member that didn't get some was Hiro. Was that a typo?

Oh no, time for choices! Let's make it two pronged.

First, how their trip goes:

1: More and more ferals show up, wanting to shower the herd in unwanted attention.

2: Hiro runs into fellow officers. A happy reunion? Or just a bit awkward.

3: They fall through a hole left by some tunnelers and end up exploring the under-tunnels

4: Though firearms are illegal, sharpened implements are available, and some people have tried to keep ponies back with daggers, swords, and anything else they can inflict harm with.

Second part, after they arrive:

1: They're treated as honored guests and questioned thoroughly about what they know about the disease.

2: The place has practically fallen to chaos, with bickering sides arguing over the newcomers.

3: It's a madhouse with refugees ready to panic, especially whenever any sign of infection appears in their midst.

4: It's become something of a military operation, making it intimidating to approach, with actual guns at the ready.

5: A religious sounding person has rallied the people around the hospital and tries to get the herd to join him. The plague is clearly God's work!
