Your demonic essence fills Ashley completely, suffusing itself to her every cell. You take stock of your new form. Muscles? Yes. Heart? Beating, good. Brain? A tad smaller than it could be, but usable. Yes, this body would do nicely.
Ashley felt a sudden headrush and dizziness, stumbling a step backwards right into Mary.
"Woah," Mary said "are you okay sis?"
"Fine, yeah, I'm fine." Ashley responded, blinking away the green from her eyes to reveal their usual hazel. "Thanks for the save."
Sloan's chirpy voice chimed in "You know Ashley, you can always go home if you're not up to it. You and Tweedle Dweeb can leave Peter to me." Cole and Trevor chuckled at the insult, both of them too pussy-whipped to stand up to Sloan.
From behind her eyes and within her ears, you witness the insults laid upon your host and her sister. This shall not stand. By the end of the night, when all hope has disappeared down your maw, Sloan will be a lifeless husk.
Peter grabbed Ashley's hand and lead her away, muttering a quick "Fuck you" as he passed Sloan. Mary trailed quickly behind, not wanting to be left with the popular kids. He stopped in an old parlor, turned to Ashley and asked "Are you okay? We can leave if you want."
Well isn't he a sweet lad. Perhaps he will make a good pet, once cums out all his freewill. Resolving to remain hidden and influence your host, rather than dominating her outright, you scheme your next move. After all, what's more fun than watching mortals torture eachother?
Though poor Mary, there at the edge of the room, she really does need help. She'll never get laid as she is, but under your guidance she would make a great seductress.
And noble Peter, he deserves a reward as only a master of pleasure can deliver. Of course, nobility also tastes the best when consumed at the moment it is betrayed.
Or perhaps Sloan's own servants must be punished first? Their guilt by association would be sweet revenge, and having two cocks at once would be a perfect way to celebrate your return.
