Pull her inside your body

You took a deep breath, looking at Chloe. Chloe, for her part, turned to look at you as well, her eyebrow quirked--you were still making her dance, but she seemed to have enough wherewithal to know something was up. "What exactly are you thinking there?"

"I'm going to... try something. If you don't mind."

Chloe rolled her eyes. "Like I have a choice. Look, do what you're going to do, I guess, get it out of your system, and then let's work on fixing this. I'll be more comfortable with this arrangement when I know there's a way out."

You nodded, and Chloe felt herself flowing back to you, this time aimed right for your mouth. When Chloe realized where she was headed, she actively seemed to help--her slime needed to absorb nutrients from a host to recharge, and being inside a host was the natural place to regain all her energy! So she seemed to have no problem with going along with what she would've wanted anyway, even if it wasn't on her terms.

You found it easier than you expected to swallow the slime, probably because it was like an extension of you and not some foreign invader. If you were about to gag or anything, you were able to control the flow to stem the reflex, and it became easier to control that reaction once enough slime was inside. At that point, the whole operation picked up steam as Chloe's remaining slime very quickly flowed into your body!

You hadn't really figured out how to 'store' the slime in you, but instead you let the slime sort of evenly fill you out. As a result, your legs and arms were longer, slightly thicker, where your hips and ass definitely saw an increase. Your breasts, as well, ballooned out--realizing you were not wearing any clothes in front of Zoe, you blushed, but by then it was too late, and Zoe wasn't making a fuss about it, so you just let everything continue. Within a minute, you stood in front of Zoe, fully permeated by slime and showing off a voluptuous figure that exceeded Zoe's own generous proportions, and yet you still maintained a girlish hourglass shape, looking quite stunning from any angle.

Zoe whistled as she saw your end result. "Really nice work there, it seems you knew what you wanted out of Chloe's slime, huh?" Your absent-minded nod as you reached down to touch your flesh told Zoe volumes, while your fingers pressed deep into your breasts. You could still feel as natural as ever, even with breasts the size of watermelons attached to you! You shook your shoulders, bounced up and down a bit, seeing everything jiggle and bounce normally. Zoe rest a hand on your shoulder. "And to top it off, you should be able to instantly redistribute that slime wherever you'd like in the body."

With a bit of a nod of understanding, you looked down, focusing. Your hips shrank as your breasts ballooned out further, just for a moment, before you had a new thought and the opposite occurred, creating more natural breast sizes while your hips expanded out twice their original size, creating such a bottom-heavy appearance that you had to brace yourself on Zoe to make sure you could account for the new weight distribution. With further focus, you were able to pull in the proportions all around, flattening Chloe's slime in your body such that you looked mostly like your usual self--with just a minor boost in your chest. A teensy one.

"You're a quick learner! Maybe... something new? Chloe can transform your body, so therefore you've got that superpower now. How about extra arms?"

You nodded, and focused, and two extra arms quickly sprouted underneath your original pair, which you seemed to have no trouble moving independently from your first set. This seemed to surprise Zoe, who began to scribble down notes on a nearby notepad. "I... guess that was too easy for a slime core, huh? How about... a second head? And let's even go a step further, see if you can let Chloe talk through it."

An odd request... but, another nod. Why not? You'd already tested out so many other features of your new slime-enhanced abilities, so what if they were getting increasingly bizarre? With an extra bit of focus, you widened your shoulders, offsetting your head to the left, while a new lump started to spring up to your head's immediate right. A lump turned into a neck, then a chin, then a head and face, flowing with green hair and a face that you immediately recognized as Chloe, although instead of looking like slime, she looked entirely human. Another impressed glance from Zoe, who didn't expect you to be able to create something so detailed from memory.

Your other head's eyes opened, and you heard a groan, as Chloe's face turned first to you, then to Zoe, before speaking. "You need to lay off the experiments for the day, you two! I'm getting tugged this way and that, it's scrambling me up! ...more so than usual. Can we pretty please get to work now?"

Zoe covered her mouth to conceal her grin. She seemed to enjoy seeing this four-armed, two-headed woman before her. "I'd personally have a lot I'd like to try out with you, still. But, I'll leave it up to Emily if she's ready to stop testing things. After all, she is the brains of the operation."

Chloe's groan in response could've shaken mountains.
