[ReadClub] Demoness Costume Pt.3 - Outline (Patreon)

Yes, yes, I am sure the title got you to open your notifications, but this is not the story—yet. I am working on it and, since part of the things I aim to be doing is giving you all peeks at what I am working on, it tracks that I should get better about sharing this kind of stuff.
While you are here, as I am wont to do when revisiting a story, I touch up previous ones to make sure everything lines up, and... [Demoness Costume Pt.1] is now twice as long as before. I had to force myself to work on Pt.3 and not get lost in revising the already longer second part, but I will probably give that one more pass before posting it to MistyFFiction.com—though you all will get to see it first (if I remember -_-).
Anyway, if you wish to not be spoiled for the story, I would advise waiting. I am trying to type enough so that the outline is behind the break, but I am also not sure how long that is, actually, but this should be enough...
 That Monday.
“-- so I told her the best thing she can do now is dump him.”
Analise forced her eyes open as the morning radio conversation continued to get louder. It was hard to believe Monday morning had come already. After Saturday night’s carnal feast, Sunday had been casual and domestic for the most part. With her still appearing to be a hyper-sexual cross-gendered demon, it was not like she and Carol could go out and do anything.
Getting home last night had been an adventure all its own, but this morning was supposedly when her body-based odyssey ended. This morning would be much, much easier. As much as she had embraced and reveled in her hyper-sexuality, no longer having almost twenty pounds of tit was going to be a relief—demonic fantasy physique or not. 
Waking up alone after she and Carol had gotten up around eleven yesterday, caused a small ache in her throat. From there the general gist is:

• In the Bathroom, Analise realizes her extreme sizes have only shrunk by ~10%—if at all.
• also has huge morning wood, like, it is bigger than ever
• “fml” she Says.
• Calls out of work.
• Tells Carol, who wants pictures.
• [Smut] Voyeuristic masturbation scene with Carol watching at work.
• In the middle of this, she gets an unexpected visitor.
• In effect, having so much sex with Carol right after her transformation caused Kyl to manifest in this world. 
• Since she is now bound to this plane her energy is cycling between them maintaining, even heightening, Analise’s transformation. 
• Really, being corrupted is weakening the barrier between Analise and her unknown magical abilities (see 212 Binding Arrangement) and, because of their blood connection, energy is flowing through her into Kylbyi’s demanding existence as it takes a lot of energy for her to remain intact in a place so alien to her biology. 
• Eventually, left as she is, Kylbyi would become human--or maybe Fay.
• [Smut] “You’ll need to fuck me and expel my energy to change back. Then I can get back to my plane.” 
• And that sort of works in that the current energy is split evenly between Ana and Kyl 
• Kylbyi does stop feeling like she is being torn apart.
• [Smut] Further sex only mingles and divides the energy again. 
• Further rooting Kylbyi here and rendering the two of them, effectively, twins.  
• This is when they figure out the above. Hell, the only reason Kylbyi could escape was suddenly having access to magic after being deprived for so long. 
• It does not seem like getting home is on the horizon for Kyl.
• Throughout all this, Carol, with demon-infused protein in her system, is also transforming from the bursts of demonic energy from Ana and Kylbyi. 
• She arrives at Analise’s half-turned and wanting more. 
• [Smut] An Eiffel Tower climax as Ana and Kyl stuff her from both ends. 
• Carol transforms in a big way.
• After a bit more feature mingling with Carol, Kylbyi decides to pose as her cousin for the interim.
• In theory, the three of them live happily for a while as a hella horny lesbian polycule, but something is bound to happen, eventually.
