Preparations

"You know, there's embracing your sexuality, Juno, and then there's... whatever this is," Kazumi observed as the two of you looked at your reflections in a mirror in your cottage.

"Too much?"

"I mean, probably, unless you're looking to use cars as vibrators. But then you're living a porn parody of a bad science-fiction B-movie."

"My life is already a porn parody of a bad science-fiction B-movie, in case you hadn't noticed. I just also happen to be the screenwriter, director, and lead actress."

"Then what does that make me?"

"Co-writer? Editor? Look, I haven't thought about this analogy too deeply," you protested.

"You're sure this isn't impacting what other people want, though, right?"

"You can check that for yourself, you know," you pointed out, but with a wave of your hand the image in the mirror changed from your reflection to one of Emilia and Safiya out for a walk.

In the few hours since you'd effectively **** them to have absurdly overdeveloped bodies, your efforts at mental stability had resulted in Safiya being able to bring her powers back under control. That didn't mean that she and Emilia had reverted to how they had been when you reunited them; their experience, however brief, of being so absurdly sexualised had left its mark on them, and you knew that both of them quite enjoyed their current appearances. So did you, for that matter, as it really wasn't too different from what you'd given yourself, just at a more reasonable scale: tall, busty, muscular, large butt, long hair, all squeezed into crop tops and short shorts. They were turning heads and being ogled, but now that she actually had a choice in the matter, you could tell that Emilia King was enjoying it.

"We could be like that, you know," Kazumi pointed out.

"Are you suggesting a double date?"

"Not when we're this big."

"Spoil my fun, would you?"

"Look, Juno, I'm not going to deny that there's a certain thrill to the thought of being fifty feet tall and smashing my way through a city, especially when we can just reverse it afterward. Or hell, even bigger, I got to looking at some weird porn while you were busy imposing yourself on everyone else, can't deny the thought of using a skyscraper as a dildo has appeal. Fuck, it made me realise I'm a freak, part of me wants to shove the sun up my cunt, just to see what it feels like. But we've also both got a cover to maintain, and making everyone not think too much about an ordinarily sexy person is different than making them not think too much about... this." Kazumi waved her hand at the mirror and it reverted to a reflection of the two of you, along with the apparently tiny furnishings behind you.

"Ugh, fine, fine," you said, and everything seemed to grow around you, apparently becoming about five and a half times larger as you shrunk yourself and your girlfriend to a mere nine feet tall.

"Still a bit on the tall side," Kazumi pointed out.

"Not excessively so, hardly by very much."

"Well, OK, but he died young because unlike you, he couldn't simply demand that physics and biology ignore him. And anyway, that still doesn't do much about these." Kazumi gestured at the mirror again and her reflection slowly turned around of its own accord.

You leaned forward a little, resting on your massive bust. "Look, I'm trying stuff out, OK? Besides, yeah, I'm not imposing myself on everyone else, but nobody thinks I'm unusual. Tautologically can't. Reality can't be unusual."

"That's just going to be your answer for everything, isn't it, it can't be unusual and I'll just use magic to get around the inconveniences."

"Look who's talking. You gave yourself the same body as me."

"To support you, Juno."

You sighed and looked in the mirror again, where Kazumi's reflection was still turning around, turning it into an arousing dance. And you could feel yourself getting aroused, watching nine feet of feminine perfection gyrate, muscles rippling, breasts big enough to rest on, shelf-sized ass bouncing, hair floating off the ground, and your own reflection looked on appreciatively, one hand slipping to its crotch, once you allowed it freedom of action. You weren't entirely sure why you'd thought to try a body quite that exaggerated, maybe you'd subconsciously picked up on some of the smut Kazumi had looked at, but you weren't ready to give it up quite yet.

"What will Brynn and Wren think?" Kazumi pointed out.

"They're mature, they know what they were made for and what they can do, or at least what they should be able to do. They know I'm the culmination of the project for which they were created."

"They weren't made for pure sexual gratification. Neither were Chloe, Zoe, Tina and Lina, for that matter. This is all your choice."

"Yeah, but it came from them and Emily at some point, didn't it? I mean, yes," you continued before Kazumi could interject, "if it weren't for you, I wouldn't have been able to embrace my sexuality at all, never mind get it under control, so exploring it might not have happened, but I wouldn't be enjoying this so much if it weren't something that some of them would've done if they could. Mostly limited by Chloe's biomass, really."

"Just because Zoe and Chloe might have done this sort of thing doesn't mean the same is true of Brynn and Wren. And anyway, Emily was entirely separate. How much of this was her?"

"A certain degree of mental compatibility was necessary for the merge to be successful," you noted. "The more compatible, the better. Emilia and Emily were both highly compatible, including with Zoe and Chloe's kinks. That's part of why Emilia's taken to her new life so well. It's a side of herself that was just never relevant to her before."

"And Emily?" Kazumi asked. "What would she have thought about all this?"

"She was definitely kinky. Wouldn't have agreed with everything I've done, though. But the sex? Well, maybe she wouldn't go quite this far, and she wouldn't have liked what I was doing before I got myself fully under control, but she'd have enjoyed exploring the sexy stuff, especially with you."

Kazumi nodded in acknowledgement. "Going back to what I was saying, though, are you really going to go to the lab with this body? Setting aside anything else, at the very least I think it would be better with smaller boobs. What's the point of having hard abs if nobody can see them?" Her reflection hefted its bust, showing off an anatomically impossible sixteen-pack.

"Not going to complain about the hair hiding the back?" you said, your own reflection turning around and parting its hair, showing off striated back muscles that flexed enticingly.

"Having a near-literal shelf for an ass means people probably aren't going to be looking at my back quite so much," Kazumi pointed out.

"And who's gonna be looking at your abs when you've got the biggest boobs in the world?" you retorted.

"People with enough refinement to appreciate a hard set of abdominal muscles," Kazumi replied, putting on a fake posh accent.

Then you both broke down laughing.

"All right, all right, fine," you said, shrinking your bust until it was only slightly bigger than what big-bust models achieved through excessive implants and surgeries. Kazumi shrunk hers to match. "I noticed you're not complaining about the length of the hair, though."

"Hey, there's something fun about having hair ten times longer than I am tall, especially when I don't have to worry about its dragging along the ground and getting dirty and tangled and all that. And anyway, it's useful." Kazumi's hair suddenly lanced toward you, forming into hundreds of hands and tickling you mercilessly.

"One day you will pay for this, Kazumi Ishida," you said as solemnly as you could while holding in your reaction.

"No I won't, because deep down you love this, or you wouldn't let me do it." Kazumi did not let up with the tickling.

"Alas! I have been found out, undone by mine own dearest friend," you said, faux-dramatically.

"Yeah, yeah, now either get to the lab so you can actually do the job you're hiding behind or get on the bed so I can fuck you silly again."

"Mmm, don't threaten me with a good time."

Kazumi sighed, rolled her eyes, and teleported the two of you out of your cottage.

--

You reappeared in your lab, Kazumi having made the area large enough that with the two of you on opposite sides of the room, the most you could do to each other without altering your bodies again was entwine the tips of your hair together.

Brynn and Wren were still sipping on the output from the microreactor, stable, but they'd clearly do better with a human host. Or if you just removed that particular need, but they'd still want to be joined with someone for other reasons anyway.

"Now do your job," Kazumi told you telepathically.

You walked over and put a hand on each of their shoulders. "Hi Brynn, Wren," you said.

"Oh, hi, Juno," Brynn replied. "Are you here to figure out more about how we can help?"

"Well, actually, I'm more here to help you, and then get out some of the early experiments to see if they can help others."

"You look different," Wren said, mostly coherent so long as she was hooked up to the reactor. "And who's she?"

Kazumi waved. "I'm Kazumi Ishida. Technically I work somewhere else at Hideki, but Juno's selfish and wants her fuck buddy around all the time, so she's abusing her authority as the Director to reassign me."

Brynn and Wren both started giggling uncontrollably at that.

"I'm trying out a different body," you said, ignoring Kazumi's introduction. "Shapeshifting like this is something the two of you can do together, at least in theory, though it might be easier if you're connected to a human host."

"It's something I feel like I should be able to do with Wren," Brynn agreed. "But neither of us is stable enough."

"Well, hopefully I can help with that. Brynn, Wren, meet Captain Kelly Lancer, who has graciously volunteered to be your host whenever you need one." Kelly appeared on a chair next to the skinsuit and the slime.

Once you'd fully discerned the degree of mental compatibility needed to effect a full merge as Emily, Zoe and Chloe had experienced, you were much more comfortable with letting Kelly, Brynn and Wren be together. They were compatible enough to be stable, but not so compatible that they'd fuse. Which was, you knew, how Kelly wanted it anyway. Having her appearance and actions controlled by other beings was intensely arousing for her.

"Uh, hi," Kelly said, clearly not really sure how to introduce herself. "Juno's told me a little about the two of you, so, I guess, whenever you're ready."

Wren disconnected from the reactor and tried to open herself up the way Zoe could, but instead she just collapsed into a long ribbon. Brynn swiftly stuck part of her to the reactor, and Wren soon regained stability.

"If I can't open up," Wren said, "how is Kelly going to get inside me?"

Kelly and Brynn shared a look at the same time that you and Kazumi did. Kazumi shook her head slightly at the same time as you nodded. "I'm not sure how well I'll be able to control Kelly's body, even if I can get inside it," the slime said. She detached from the reactor herself, and immediately started to deform slightly, her human shape losing cohesion. She put a hand back on it shortly after and, just as Wren had, became stable again.

"It's OK," Kelly said. "I trust that Juno won't let us come to any real harm. How would you like to get inside me?"

"I think, my instincts are saying I just, kinda, flow over you and go in through your mouth?" Brynn said. Unlike Chloe, she'd never actually tried joining with anyone, not even Wren.

"Oh," Kelly said, sounding a bit disappointed. "I was hoping for something maybe a little more intimate."

"Well, once I'm inside you I can get as intimate with you as you want," Brynn said. "If I can control you, anyway. Never tested that."

"What about Wren, though?" Kelly asked.

"We'll help this time," Kazumi said before you could answer. "Hopefully being attached to a human host will help stabilise her compression cage further and make it easier for the three of you to bond in future."

"That assumes I'll ever want to not be bonded," Kelly noted.

"I'm not sure if the three of you could take being together permanently," you said. "I can already tell you won't undergo the same sort of gestalt fusion that Zoe, Chloe and Emily did." Kelly's face actually brightened a little at that, since it meant that she'd retain her own consciousness and be aware of being controlled.

Kelly turned to Brynn. "Would it be easier if you were connected to the reactor or not?" she asked.

"Don't do it while she's connected," Kazumi said sternly. "The current from that thing will pass right through them and fry you alive, Kelly. And I know you're a masochist but you don't want the entire output of a direct-conversion microfusion reactor slamming into you."

Kelly nodded, and then Brynn said, "On three, then. One, two..." The slime detached from the reactor and jumped into Kelly's lap even as she deformed, her melting face pressing against Kelly's, kissing her as best she could while flowing down her throat.

The military captain shuddered as Brynn's consciousness wired into her synapses, the slime slowly acclimating herself to the feeling of controlling another body, one that didn't start collapsing into a pile of goo when not connected to a power source.

"This is what having a proper body feels like?" Brynn said in Kelly's voice.

"You had a proper body, Brynn," you told her. "Hideki just wasn't willing to put in the effort to make it work as intended, and anyway I knew you'd like this better."

"I do," said Brynn, experimenting with shifting her slime mass around Kelly's body a bit. Kelly couldn't communicate, of course, but both you and Kazumi could detect her consciousness telepathically, and she was getting excited at what was happening. With Brynn's in control, however, that excitement wasn't even reflected on her body.

"What about me?" Wren asked. "How am I supposed to get Kelly inside me if I can't even form a stable inside?"

"Just trust us," Kazumi said. "I think, after the first time, you'll start finding it easier in future."

Wren looked uncertain, but disconnected from the reactor, collapsing into a long ribbon again. You walked over and found the part corresponding to her feet.

"Brynn, if you'd lie down in the antigrav generator?" you requested. Kazumi rolled her eyes at you as you just made the device appear without allowing Brynn to notice.

Brynn stood up and walked, a bit unsteady, to the designated spot, floating up and lying back as gravity's grip on her relaxed.

Taking Wren's ribbon, you attached the part of it that should form Wren's right foot to Kelly's. Kazumi found the other foot, and you wrapped Wren around Kelly's body as if you were mummifying her. About halfway through, once you were at Kelly's belly button, Wren leapt out of your hands, the connection to a human body giving her enough control to start to stabilise her compression cage, snapping into place.

"How does that feel, Brynn, Wren?" you asked.

"It feels pretty good. Better than the reactor," Kelly's voice said. "I don't feel like it's all that hard for me to maintain the cage, though I feel like there's more I should be able to do and also it feels like I could be attached to someone better."

"And I think I'm getting a handle on controlling this body from the inside," the same voice continued, though this time it was Brynn's consciousness using it. "It's easier with Wren around it, like we're meant to be together like this. But I agree with her, it feels like we could have a better fusion with a different body."

"You probably could," you agreed, "but I doubt I could find a more willing volunteer. How about you practice controlling that body, Brynn"--Kelly would have squirmed in pleasure at the partial objectification--"while Wren, you should be able to do some shapeshifting, especially with Brynn there to help you redistribute mass. Properly you shouldn't even need Brynn, but she'll help for now, and it will probably make it easier for you to retain a solid form while disconnected."

Kelly's head nodded. "What will you do?"

"As I said, I'm going to get some of the earliest experiments out of storage. Nothing like you, they're just tiny gels and small bits of skin, bandages basically. But that'll be the basis of what I think Project Inside Out should always have been for."

Kelly nodded again and you walked over to the door to the storage area, Kazumi simply teleporting across to join you as you walked in.

With another thought, Tori appeared in the storage area next to you, just as naked as both of you, with the body of a lusciously curvy nine-tailed kitsune.

"Mmm," she said, looking at both of you appreciatively, "wanting to get a little threesome action in? But you're still not ready to give me something hard like you know I want."

"Is she always this horny?" Kazumi stage-whispered to you.

"No," Tori said, "usually I'm hornier, at least for Juno." She looked Kazumi up and down. "You, I'd definitely need you to have something hard if you want to get between my legs. Juno's special."

"Did you..." Kazumi trailed off, but you knew what she was thinking.

"Not deliberately," you said. "Difference between being all-powerful and being reality. Tori can't help but want to fuck me since it's kinda like masturbation. You? Well, she told you what she wants."

"You know, I'd definitely be down to be spitroasted by you two," Tori put in.

"I looked at enough porn, can't say I'm averse to it if Juno isn't," Kazumi said. "But maybe let's get back to the task at hand?"

You opened a drawer, revealing the very earliest prototypes created for Project Inside Out. "Mental connection test now, talk about sex later," you told Tori sternly.

"Fine. But I'm gonna want that spitroast sooner or later." She smirked at Kazumi. "I'm yours as soon as you can convince Juno."

Your hair reached over and yanked hard on one of Tori's tails. "Slime or skin?"
