"So, Julie? I've been thinking. Can you tell us more about unbirth?" Dan started coughing as Lily's question caused him to unexpectedly inhale a large amount of water. After helping retrieve Lily from his womb, Julie had let them use her shower to clean themselves off. As Dan was getting dressed (he hadn't thought to bring any clothes for Lily), she'd offered them both drinks; both had requested tap water, because they were fancy like that. Dan and Julie were sat opposite one another at her small, 2-person dining table, with Lily in a micro chair on the table between them. Dan had been surprised that Julie had micro furniture, but Lily's question had reminded him that she did have a reason to have micros in her house. Julie grinned down at Lily.

"Sure! What would you like to know?" Lily blushed.

"Well, you said you do, uh, it, sometimes?"

"Yeah?"

"I was wondering... well, I guess I was wondering how often?"

"Well, it kinda varies. It really depends on when my partners have free time." Dan, finally having recovered from almost drowning in a glass of water, joined the conversation, his voice a little hoarse.

"How long do you nor- cough, cough... uh, 'scuse me. Um, how long do you normally keep... uh, I mean, how long do they normally stay in, uh..."

"In my womb?" Julie grinned at him. "Come on, I just stuck my favourite toy in you! I think we're past that sort of embarrassment." She giggled, then shrugged in answer to his question. "Again, it varies. It's mainly limited by the micro. As you guys discovered, you can breathe in there just fine, so the main limiting factors physiologically are food and water, and even then you can just take bottled water and boxes of food in with you. My partner once spent a whole week inside me. In reality, it's normally down to when they have to go back to work or whatever."

"A week!?" Dan exclaimed, but Lily had another question.

"You keep saying 'your partner.' Are they a boyfriend or girlfriend?" Julie shook her head.

"No, just a close friend. In fact, she already-"

She was cut off as the doorbell rang, and excused herself to go and answer it. She was gone barely long enough for the pair to exchange a look before she returned, a hand behind her back and a bashful look on her face.

"Um, so, I thought you might start asking me these kinds of questions, so while you were showering I made a call. So, um..." She brought the hand out from behind her back. "This is Kate." Dan and Lily immediately recognised the micro receptionist lady from the lab, who waved at them.

"Hey, guys!" Julie put her on the table. She looked to be in her mid twenties, and fairly average height for a micro, standing about 5' 5" in micro scale. She had dark red hair that hung in loose curls down her back as far as the top of her butt. She was quite buxom, with long, slender legs leading up to a round butt, and boobs even bigger than the ones currently adorning Dan's chest; he estimated they were at least H-cups, though it was hard to estimate given the size difference and the fact that they were currently resting on a huge pregnant belly, which looked as though she might need to be rushed to the hospital at any moment. She was packed tightly into a short, deep red dress in a similar style to Julie's blue one. Julie grinned at them.

"So, that partner you were just asking about?" She gestured to Kate. Lily walked over to the tiny woman, hand out to shake, heedless of her own nudity.

"Hi, nice to meet you!" The pregnant girl took her hand and shook it.

"Hi! You must be Lily?" Lily glanced up at Julie, who nodded.

"Yeah, Kate knows about Dr Stone's work, and she knows you're swapped."

"And I know you didn't travel here in a pocket!" Kate added with a giggle, which Lily joined in with. "So," she turned to Julie. "What did you want my help with?" Julie blushed uncharacteristically.

"Well, these two are, um, curious about unbirth. If you're ok with it, I thought maybe we could... give them a demonstration?" Even before she finished speaking, Kate was stripping, peeling the dress off herself.

"I'm in." She considered her words, then giggled. "Well, not yet, but I'm about to be!" Julie laughed as she headed for the bedroom. Dan, caught off guard, picked up the two micros and followed her.

Even in Lily's body, Dan still considered himself to be a straight guy. As a micro, of course, he'd never been able to pick someone up, and the only micros he'd really interacted with since swapping were Dr Stone and Lily (who was, of course, in his own male body). As a result, this was the first time he'd picked up a female micro, and he was surprised at how different it felt. With Lily in one hand and Kate in the other, he was able to make a direct, one-to-one comparison. She felt noticeably softer in his hand. She wasn't any lighter, but he guessed her pregnancy had a lot to do with that. His thumb gently stroked over her belly, and he didn't realise it had slipped between her legs until she wriggled and moaned.

"Mmm, you're good with your hands, I'll give you that." He looked down to see her grinding gently against his thumb. He was about to apologise when Julie answered.

"He's good with his tongue, too." The big-bellied girl in his hand giggled.

Julie was still naked from their earlier session, so she simply turned and lay on her bed, spreading her legs. Dan put Kate down between her legs, and the little woman immediately started working on the pussy before her.

"How long do you want me to stay in there this time?" Julie considered.

"Hmm... a couple of-nnf... hours?"

"Sounds good to me." Kate pushed a hand into Julie, then the other, but as she reached her elbows, she hesitated. She felt around for a moment, then giggled. "Oh, you guys had some fun earlier, huh?" Then, to Dan and Lily's surprise, she started pulling back out. The reason soon became clear as Julie's honeypot bulged outwards, then suddenly opened to reveal the base of the little black dildo Dan had used on her earlier. The blonde girl giggled.

"Oops, did I- oh, fuck... forget about my toy?" She asked playfully, winking at Dan. Kate slowly pulled the toy out of Julie and picked it up, turning to Dan.

"Hold this, will you?" He took it and went to place it on the bedside table. "No, wait, keep hold of it. I think you're about to need it again in a minute." She turned back to the (relatively) giant pussy before her and stuck her hands inside again.

The difference in experience between Dan and Julie was apparent; in seconds, Kate was waist-deep in Julie's pussy, despite her big tits and massive belly. Just a few more seconds, and she'd managed to wiggle inside completely. Being shorter than Lily, and with Julie's greater experience, Kate managed to fit entirely into Julie despite her huge tits and massive belly. The blonde girl's outer lips were able to close completely around her living toy. She was bucking her hips, moaning furiously as she looked up at Dan.

"Hey, Dan, yoooooOOOHHHHH, fuck yeah! You're gonna need to uuuuUUUUSE that dildo to PUUUUUUSH her through my cervix when I cuuuUUUUUUUMMMMMM!!!!! Um, 'cos otherwise she'll juuuUUUUST slip back ooOOHHH MY GOD. Uh, she'll just slip out agaaaaAAAAAAANNNNNGGHGHH!!!!!!!" She slipped back into pleasured screaming, and Dan realised she was getting close. Obediently, he reached between her legs, before realising he'd done it with the hand holding Lily. Hastily, he switched to the one with the dildo, which he gently pushed into Julie's cunt. She moaned as he pressed it in, and just as he started feeling the resistance from Kate's feet, Julie came. The muscles in her lower belly tensed, and he was shocked to realise he could actually see the rough shape of Kate's body within Julie, the triple bumps of her boobs and belly moving upwards into the blonde girl as he pushed the dildo in after her, forcing her deeper.

At last, Julie's orgasm came to an end, her passenger curled safely up inside her and the dildo once again buried in her cunt. Dan moaned, and suddenly realised that his hand had accidentally slipped between his own legs to tease his clit as he'd watched the show. He hastily removed it, revealing the damp face of his girlfriend grinning up at him.

"Uh, sorry." She said nothing, but her grin grew wider. He turned his attention back to Julie, panting on the bed.

"And that... is unbirth..." she gasped between breaths.

"It certainly was." Lily said.

"Is she ok in there?" Dan asked. Julie nodded.

"Yeah. We have a system; one kick is 'no,' two is 'yes' and any more than that is 'get me the fuck out of here.' So, I'd know if she was in trouble because she'd be kicking up a storm so big even you guys would know about it." Dan gave a surprisingly feminine giggle, then covered it up by pretending to clear his throat.

"So, is that how you'd know if she went into labour?" Lily asked.

"Labour? What do you- oh." Julie was a little confused for a moment, before realisation seemed to hit her. "Well, yeah, I guess it would, but there's no risk of that today, she's only seven months along."

"Seven months?" Lily asked incredulously. "But she looked so huge!"

"Seven months with triplets." Julie clarified. Lily's mouth opened in a silent 'O' of comprehension. "Anyway, you guys want a closer look?" She patted her lower belly. Dan knelt next to her, dropping Lily onto her. As when Lily had been inside Dan, there was a small bulge in her belly. It was a little more noticeable on Julie, simply because she was a little slimmer, but still small enough to be easy to hide, or even just explain away as baby fat. Lily lay down and pressed her ear to the belly.

"I can hear her!"

"Really?" Julie sounded interested. "I know normies can't hear people inside, but I've never done this with another micro around. Can you really hear her?"

"Yes, she says..." Lily suddenly blushed as she listened. She sat up onto her haunches, kneeling on Julie's belly. "Well, she's fine in there."

"Great." Said Julie, an enigmatic smile on her face. "Well, what do you say I give you a lift home?"

-------------------------------------------------------------------------------------

Dan once again found himself riding in the front passenger seat of Julie's car, grunting slightly every time the broken suspension went over a bump. The journey was a lot less arousing with Lily riding on his knee, though his tits still bounced around like crazy. Julie apparently had more self-control than he did, but she was biting her lip slightly. He decided to ask her a question to distract her.

"Hey, so Julie, how many micros have you had in there at once?"

"Well, like I-nff... uh, like I said, I've only ever done it with Kate before, so, uh, one. I've always wanted to try mmmhhh... er, more, but I don't know anyone else I can even talk to it about."

"There must be some way." Lily interjected. "Online, or something."

"Well, I could go look for someone online who'd be into it, but I don't really want to stick someone I don't know up my cooch, you know? The only other option would be to get a Micropolis, but you've seen my apartment, I don't have space for one." Dan and Lily exchanged a glance, confused.

"Micropolis? What's that?" Dan voiced the question both of them were wondering. Julie glanced at them.

"You know, a Micropolis. A micro city?"

"That's a thing?" Julie looked at Lily, then Dan, perplexed.

"You've really never heard of them?" They both shook their heads, so she launched into an explanation.

"Well, after the virus hit, the government was concerned about the possible issues that might come from normies and micros trying to co-exist."

"That makes sense," interjected Lily. "It's so easy for a normie to accidentally kill a micro just by stepping on them." Julie nodded.

"Some of them thought the only way to prevent that sort of thing was to fully segregate everything, by having micros live in small, self-contained cities, which they called Micropolises. You know, like a 'micro metropolis.'"

"Fair enough," said Dan.

"Yeah. The problem was, it was hard to find a good place to build a Micropolis. Most cities didn't want a Micropolis, because it would mean a lot of traffic all needing to go to a single place, and because there was still a whole bunch of legal wrangling over who'd get jurisdiction, who'd have to handle utilities like power and water, that sort of thing, so most landowners refused permission to build a Micropolis on their land."

"Gotta love red tape," Lily giggled.

"Yup. So anyway, the people in charge of the plan weren't quite ready to give up. They started asking ordinary people to let them build a Micropolis on their unused lots, in their gardens, even in unused rooms in their house."

"I'm guessing it didn't work." Dan said, but Julie shook her head.

"Actually, quite a few people took up the offer. I'm guessing it was something to do with the massive grants they started offering to anyone who agreed to let them build one on their land."

"So, how come we've never heard of this before now?" Lily asked.

"Well, a few months after they started offering Micropolis grants, the government realised they could save a lot of money if they just segregated existing cities instead. So they did that, and stopped advertising Micropolises."

"I think I can see where this is going." Dan interjected. "They stopped advertising them..."

"But they didn't stop offering them?" Lily finished his sentence. Julie grinned.

"Got it in one. If you know the website to go to, there's still an online form you can fill out. A friend of mine tried it a few months ago, for a laugh, and a week later a bunch of workmen turned up ready to start building." She sighed. "I've been on the site so many times, but it says it needs at least a thousand square feet, and my whole apartment's barely a third of that, so it's not happening."

They were silent for nearly five minutes. Dan's mind was swimming as he considered what Julie had just told them. It was Lily that first broke the silence.

"Hey, Dan?"

"Yeah?"

"How big is our garden?"

-------------------------------------------------------------------------------------

A few minutes later, Julie pulled over outside Dan and Lily's house. She turned to them.

"A couple of things before you go in. First off, are you really serious about getting a Micropolis?" Dan looked down at Lily, who nodded. "Ok, great! So, the website is www.micropolis.gov/apply. Like I said, I've been on there a lot, so here's a tip; when you get to the 'Type of Micropolis' page, click the dot above the first 'i', then click the middle of the plus sign. I don't want to push you into anything, but... I think you might appreciate what that does. Anyway, the other thing." She pulled out her phone. "Here's my number. You know, in case you have any more 'accidents.'" She winked. Dan put her number into Lily's phone as she did the same with his, then they both thanked Julie again for the help and Dan headed into the house, Lily's still-nude body carefully hidden in his chest pocket.

Inside, Dan, making an educated guess at what Lily would want to do, headed for the spare bedroom, where she kept her rarely-used computer. He logged on (it was fingerprint-locked) and opened the website Julie had given them as Lily climbed out of the pocket and sat on the desk, facing the screen. As Julie had said, it brought up an online form. The first several pages were pretty dry. Initially it asked for things like their names, ages, address and so on. Then came the question of where they wanted the Micropolis building; they said garden, the only place they had that was over a thousand square feet.

The next page was the one they'd been waiting for.

Type of Micropolis

Standard: A normal Micropolis with no particular specialisation.

Child-friendly: A Micropolis specialised for hosting micro children, including nurseries, play areas and other suitable amenities.

Lily frowned.

"I don't see a plus sign anywhere." Dan shrugged and, as Julie had suggested, clicked the dot above the first 'i' in the header. A third option appeared below the other two.

Adult (18+): A Micropolis fitted with equipment for adult use. Not suitable for children.

"There's the plus sign," said Lily excitedly. Dan clicked in the middle of it, and a fourth option appeared.

Adult Super (18+): An adult Micropolis, modified with additional equipment to fulfil unique needs. Inquire for details. Not suitable for children or adults of a nervous disposition.

There was no indication of where they should inquire. Dan looked down at Lily, who shrugged.

"You already know which option I want." He grinned, clicking on Adult Super.

The four options disappeared, replaced by a new screen.

Please select a name for your Micropolis (Note: all names subject to review)

Beneath was a simple text box, the cursor already flashing in it. Below that was a 'confirm' button.

"We have to come up with a name?" Lily asked, surprised.

"Apparently so." The two of them thought for a while.

"What about 'Tinytown?'" Dan asked. Lily shook her head. "Yeah, that sounds dumb."

"Why don't we name it after one of us?" Lily suggested. "'Danton' sounds like a good name for a town."

"Or a fireplace brand. 'Lilyton' sounds a lot better."

"No, I think Danton sounds better."

"Alright, Lilyton it is," Dan giggled as he started typing. Lily laughed, leapt to her feet and tried to stop him, but he simply grabbed her and held her one-handed as he typed 'Lilyton' into the box with his other hand and hit confirm.

"Dick," Lily giggled as the screen changed again. Instead of more questions, it simply read 'Thank you for your application. It is now being reviewed. You can expect a reply in three to four working days.' Dan looked down at Lily.

"Bedroom?" Her face lit up and she nodded.

"Bedroom."
