Horny goddesses and a smug angel won't shut up

The last thing she remembered was weightlessness, a loud crash, and then darkness.

Then more darkness and weightlessness, but now a pair of self-proclaimed goddesses were floating in front of her. "Do not avert your gaze, mortal! We have seen your desires!"

After a moment she asked the goddesses, "Is this a goddamn isekai? Did I just die?"

The golden-eyed Carnachias snorted. "So you've already figured Mel out, huh?"

"I am Melanoche, Carnachias, you know-"

"Yeah yeah. Seems it'll be easier for both of us if I explain. Yeah, you died. That elevator you were in crashed. But we sensed all your dark horny fantasies, and needed an OP otherworlder to sick on the one summoned by the Light. So we'll turn you into whatever sexy monster you want, and let you loose. Sound good?" Carnachias didn't even wait for a response, seeing the gears turning and the slowly forming malicious smile on her face.

She had been a bootlicking corporate stooge, one who clocked in but never really got to clock out. She'd worked her ass off, and swallowed all sorts of indignities, all to eventually work her way up the ladder and live with a modicum of authority and comfort. But it sounded like her cheap bosses had been even worse than she thought, as out of nowhere the elevator she'd been riding had its cables snap, sending her on a twenty story fall.

But now, she could be someone, something else.

With that, Carnachias went into the explanation of how this would work. What powers were available. Carnachias also suggested, "Grab the Ranger class and Elf lore, that sounds like you'll get some real fun out of it. Show those sexy virgins what it feels like to get their brains fucked out."

Carnachias went on to explain that among the races of Light, elves were far and away the most numerous and prosperous. Their magic allowed their forests to expand outward, swallowing up cities previously ruled by the Dark, drastically changing the surface of the world of Ruyanei. They were an all-female species, who had gone almost entirely without sex for nearly a millennium, having mastered an immaculate conception magic.

With that in mind, she knew what her knew name would be. "Call me Demon King Elffucker. Elle for short."

Carnachias' golden eyes glimmered with a mix of amusement and arousal. "I haven't been this excited about a Demon King since my old fave Murderrape!"

Melanoche interjected, "As long as it isn't just elves you're fucking. That current Demon King hasn't paid us proper respect, so dethrone her and give her a lesson in submission."

So the goal was to fuck some elves, conquer their kingdoms, fuck the current Demon King, take the throne of Demon King, and wipe out the heroes. Simple.

That was the plan when Elle left the goddesses, but then an annoying angel found and pestered her.

She absently nodded along to his words, having little interest in the alternate cores he offered.

But then he started listing off oaths she could make in exchange for special perks. One of them was "Love Humanity." Elle eagerly accepted that one, as she had little interest in (personally) targeting humans. Fortunately, human was an interchangeable term used to refer to the specific species of humans Elle had once been a part of, and also an umbrella term for the races of the Light. So elves were a tempting little loophole Elle couldn't overlook, especially as Ariel bragged about the perks she could get for swearing one little oath.

And so, with the benefit of more power than she had expected to start off with, she finally appeared on Ruyanei.
