Please Help Me. My wife is stuggling to find books in her very unique taste. She wants to explore the world of smut, dark smut, and whatever the next level is beyond dark smut. I am challenging reddit to help me, help my wife.

My wife is looking for Non Consensual with no happy ending, no romance, with rape, torture, brutal, explicit details and a deep sexual desire from male protagonist and his joy to conquer over the female. A large amount of berating the female, she wants the females throat to be punished so horribly that she cant even sob about it. Just as an example… This her request for the first book. She is also looking for…

Strangers turned to lovers, no relationship, basically great sex with extreme detail both using each other for their deepest darkest kinks. No love, no soft sappy bullshit. Lots of risky sexual encounters sense of danger but not from each other. Possibly with a rich male. If you have ever seen the netflix show "365" something like that in a book.
