A couple of tense moments passed as Zoe held her breath, continuing to hold back the desires that were welling up within her as she awaited Casey's response. "So...what happens if you wait too long? You said it's getting harder to hold it back."
"Apparently it'll just keep getting harder and harder, until I won't be able to control myself any more. And if the first time that happened is any hint, things might get very bad."
"'First time'?"
"Yeah, uh...I wrecked the restroom I went to after our argument. That was when the demon tried to take control of me and gave me this." Zoe pointed at the seal on her chest. "I stopped her from taking control of my soul, but my body...well, let's just say this is already toned down from how I looked in the restroom."
"Really..." Casey trailed off in wonderment, her eyes wandering around to takw in her friend's new form.
Zoe caught sight of Casey apparently not entirely put off by this whole episode, and had to stifle a moan as a wave pulsed through her body. That demon was not going to give her a rest, was she? Casey reflexively pulled back at the sudden motion as Zoe felt the pulse rise up within to her breasts, feeling them becoming more sensitive as they pushed out on her makeshift crop top, making it even tighter and a little bit more obvious how aroused Zoe was becoming the longer she was there.
"Zoe? You OK?" Casey's voice immediately shifted to concern.
Zoe needed a couple of breaths to collect herself. "Yeah, yeah I'm OK. Just..." She looked back at Casey. "Are you...do you..."
"I'll admit, yeah, it does sound crazy. But we've known each other for years now, Zoe, and you're not a liar -- if you say that's what's happening to you, then I'm gonna believe you. You're my friend. And from the looks of things, you're in trouble. And I can help." With an inhale, Casey leaned forward and embraced Zoe in a hug. "Besides, you look hot right now." The sudden breathiness of Casey's voice would lay to rest any doubts about Casey's decision.
Zoe gasped, doing her best to now contain two things: her growing inhuman desires, and now the wave of excitement that, yes, this could actually work! Take that, succubus demon! The excitement was short-lived when she heard the sound of tearing fabric as another pulse coursed through her body, pushing out her chest a little more and now also pounding out her thighs. "Casey, wait, I..." She (increasingly reluctantly) broke off the hug from her friend, at least for the moment.
"What's wrong? Didn't you say you need this?"
"That's not it, it's just...I'm pretty certain I'm gonna really transform if we do this."
"Yeah, even I felt your boobs grow there! But like I said, I'm ready to help."
"I'm not gonna look human, Casey. I'm a monster." Greg...
Casey placed her hand and caressed Zoe's face, which was already slowly starting to shift. "You fought off that demon for your soul. As long as I know it's you in there...I'm ready for anything."
