Dark/evil literotica

Hi!
If this needs to be posted elsewhere please let me know?

My wife has a vicious dark side (which I adore)

Anyway, she’s been having a hard time getting revved up.
I suggested literotica and she loved the idea.

I’m now on a quest (from her) to find the most brutal, violent, screwed up, evil and possibly gory literotica.
She expressed short stories would be most effective for our application (but not too short) that also aren’t too ridiculous or goofy

Could some lovely folks Make some suggestions for authors like this or collections of stories?

If it’s on Amazon or some other digital platform that would be nice.
But if something that fits the bill is only in paperback that’s fine.

She likes bi but prefers men so bonus points if some lesbian content is also included in the same codex of sexual corruption.

Thank you so much!
