After a long minute to collect her wits back and be confident she really was in control, Zoe turned her eyes back to the mirror. Her new succubus form -- sexy, voluptuous, demonic -- looked back at her. Obviously there was no way she could walk (or fly) out of there unseen, and she didn't particularly want to make a dingy public bathroom her new home. But Zoe still felt she had to talk to someone about this, someone other than the demonic spirit she had invited in and had become the world's most unwelcome guest to her. Who, though?
"Casey..." Zoe remembered their last conversation dissolving into a public blowup when the demon first appeared. She had to apologize for that...and, maybe, be the most likely person for her to tell this whole secret about?
"Yes...perhaps your friend can be your first servant..."
"Shut up!" Zoe shut her eyes for a moment to try to will silence upon the demon's voice in her head. She opened them again, looking back at the mirror. It would certainly be easier to do so if her own looks wouldn't immediately cause fear (Or lust? Zoe didn't know if Casey swung that way -- it wasn't something that had come up before.)
A sudden onset of what felt like cramps took Zoe out of her thoughts as she let out a low hiss. She curled her body out of instinct, letting her get a glimpse via the mirror of the wings on her back shrinking smaller, receding back into herself. The horns on her head would follow as the dark crimson red on her skin slowly faded away back to her original color. A small pain in her lower back would draw a hand, now softer and unclawed, there to feel the last bit of her tail disappear as well. It wouldn't be long before the pain faded away, leaving Zoe to look back over herself again. She looked fully human once more, though not quite as she was before all this began -- she was still taller, her muscles still seemed visibly and her abs still toned, and her breasts, though no longer as absurdly large as they were when she was transformed, were still D cups. And also she was still naked, her clothes long ruined by the initial transformation now just tatters strewn about the concrete floor nearby the holes her previously clawed hands had made when she was in the midst of her struggle for her mind and soul. Zoe tried to will herself to change all the way back to how she looked before, but nothing happened.
And Zoe still felt...off, somehow. She felt a bit claustrophobic, like she had been stuffed in a locker even though the bathroom itself was rather spacious. It wasn't the fact that her new human body was actually a little taller than before -- this felt...different.
"Of course, my dear Zoe." The demon's voice piped in again with unsolicited advice, apparently knowing what Zoe was confused about. "This human body, even inrproved from your previously pathetic form, is still limiting to you by the very fact that your true form is a succubus. This shell you have stuffed yourself into can't hold you indefinitely, for your nature will fight against it."
"So what are you saying? I can't stay like this forever?"
"I doubt you could hold it for more than a few hours before it becomes unbearable even for you. And when you do succumb, your hunger will be all the more stronger for having been denied even your true self for so long..."
So a time limit. Great. And she might be even more..."voracious" out the other side. If Zoe wanted to square things away with Casey while she could as herself, it'd have to be sooner rather than later.
