This is an extremely important question and I’m sorry it took me a bit to answer. (It’s been a hellish few weeks lol) But, yes yes, I like where your head is at.
For starters, it’s...rather messy. (Approx 2 Liters of electrolyte lotion per round - 1 Liter per prince.) Furthermore, she won’t “explode” explode. Unless explode is a euphemism for orgasm, and then yes I suppose she will. She’ll mostly just get knocked out by each round, or at least that’s how I’m planning it. That’ll kind of give Leviathan and Lucifer some angst to work with when they physically can’t get enough of her to warrant the hours where they aren’t allowed to just keep her in bed all day. She has a job after all.
As her magic grows, her stamina and tolerance for relations with her demons will grow as well. Demon queens have to be capable of meeting the needs of their mates, of course. Especially the Queen of Queens. The mate of Leviathan (The Prince of Princes aka the true King of Vesperis) and Lucifer (the “youngest” prince).
