At least let Zoe talk again!

You were helpless to stop Chloe's plan, whatever it was. She had control of the limbs, and it was up to Zoe to open up to let you and Chloe out of her body again, but she didn't seem to do that, likely because she wanted a head back first, and that required Chloe's help. Despite that, you still had at least one angle of protest.

"Zoe should really be able to speak, you need to give her control of your mouth or a mouth of her own!"

You were surprised you'd be making such a request. You could've just said "let me out" but apparently, the situation had some appeal to you as well. Being carried around, sort of lost to Chloe's will...

Chloe sighed. "Fine, fine! Oh, I have an idea, hold on." You felt something strange between the legs, as Chloe transformed the crotch back to Zoe's pussy, leaving only her eyes hovering above the fabric of the panties. Moments later, you felt a new tingle, this time coming from the breasts. Chloe used the hands she controlled to pull the labcoat away again, undoing the bra she had recently put on, to check her work.

Your nipples had been replaced with two pairs of lips! You felt them stretch open, sort of like a yawn, before they began to speak.

"There, how's that? We're even now," said the right breast, in Chloe's voice.

"What? Hardly! You've hijacked my head! I don't call that even," spoke the left breast, clearly as Zoe.

Zoe's hands reached up to grab and squeeze at the breasts, eliciting three moans from three different mouths. "Nnh, it's not like it's all bad for you, Zoe. After all, our friend Emily's getting used to wearing your body, she's getting used to my slime, isn't that right Emily?"

"Uh, yeah, of course." You were still registering the talking breasts, you didn't even really realize what you'd just acknowledged.

Zoe's mouth pouted a little, which felt so strange, like your nipple was being tweaked by an unseen hand. "Well, fine. But if we're going out, make it quick, I've got some samples that need processing this afternoon so I have to be back. And don't freak Emily out in public or I will expel you without a second thought, Chloe! Doesn't matter where!"

Chloe giggles, enjoying a bit of the drama it seems as she began to put clothes back on your three-way shared body. "We'll go to the coffee shop and down to that one store you like to try on some clothes, I never get to control you so much so I never get to put you in the outfits I think would look really good on you."
