I know this is a long shot, but I have to try.
I remember reading an ongoing story about a woman that stubbies into a BDSM relationship with a demon. Pretty standard so far, but the trust of the story was that she is a Fell, a being the literally burns the sin from existence by magnifying it. This is why she had an overall shitty life up to that point.

There is more I remember, but I also don’t want to spoil too much for anyone else because it was a really good series.

P.S. I think I originally read the story on Literotica, but I can’t be sure.

I can’t find an old non-human story.
The general idea of the story:
A human gets saved by a demon of lust. Ends up being one of the demon kings (of lust)
She ends up being a Fell, which burns out all sin. That is the cause of all her “friends” betraying her in the past.
Said demon king of lust tries converting her to a demon without letting the other demon kings realize what she is.

Heavy bdsm undertones. Like one scene they “play” hide and seek, and she bends the rules by hanging out a window. For “breaking” the rules, she is taken right there on the bed.
