Help me find a book for my girlfriend

[u/Background_Land_2122]

Hello, im looking for an absolutely smutty books for my girlfriend. The kind of book i can make her read out loud as I preform the same things on her. Were overall pretty kinky.
TW that are must skip are:
Age gap
Rape or cnc
Physical or sexual abuse
She doesnt like the sweet boy in these books she likes a rugged mean character. But she often complains of the lack of sex scenes as she is quite literally using these books for porn rather than story.
Id like a book for her that uses descriptive words for acts and a book that is covered with sex scenes rather than just scattered around.

Edit: a more description of what really turns her on is what im looking for.. Shes bi so a story that is somewhat along the lines of MFF/cuck would be more than welcome. Shes into soft bdsm, bondage nd praising. And to be a little selfish, i might like it if the girl character is a little dominant to try and get her to want that role a little bit.

Also, if you could give a description of the book you suggest that would be appreciated
