Need something with knock out drag out sex

Really struggling to find books that satisfy the proverbial ITCH. I want chapters-long sex with iffy themes like dubcon (not outright noncon) where the fem is just being absolutely railed against a wall etc. The sex scenes do not have to consume the entire book, I still want a healthy heavy plot.

I’ve read some dark romance liked Feathers So Vicious and that is not my cup of tea but I also want a bit more umph.

I’ve read all of Ella Fields stuff and it’s good but I do prefer slow burns, multi books. Preferably first POV.

Please help!
