Books relating to sexuality, overt sexual themes, or sex work?

i just started working at an “adult boutique” (we sell sex toys, lingerie, whips, gags, pornos, the like) and was just informed that i can read on the clock during my down time, but that it has to be relevant to the subject matter of the store. i’m honestly not that interested in reading pure smut novels, and tend to prefer books like that of the game of thrones series, dune, some warhammer 40k, anne rice’s vampire chronicles, the girl with all the gifts, the witcher series, etc…

it seems like books somewhat in the vein (hah) of interview with a vampire would probably the theme slightly with how sensual it is, but i’m looking for more books to add to my list as i tear through them decently quickly. any recommendations?

the bar for acceptable books is apparently not very high as she gave “the child called it” as a fringe example as it deals with themes of sexual abuse, for instance. not super sexy at all in my opinion but it gives me an idea of how loose the standard is. help?
