Smutty books that are very dark (don’t have to be atrocious just very kinky)

I would love a dark romance featuring WLW as I haven’t heard people talk about a lot of them. Recs would be really appreciated, trigger warnings don’t matter to me as I’ve read some dark shit aha. P.s doesn’t have to be extremely dark just a smutty WLW romance ^{_^} thank you.
