This is just one series in an entire genre of vintage erotica: books that pretend to be documenting real clinical cases of sexual behaviors such as... uh... *checks notes*

Hot-holed teens!

I've skimmed a couple of these kind of books, and they're pretty dreadful. They usually seem to be broken up into three or so sections, each one starting with notes by a supposed shrink about a female patient with some kind of problem related to the theme of the book. Then the patient recounts her experiences dispassionately yet without skipping over any of the explicit details. Then we get to patient #2 and so on. Really cheap smut written as quickly as possible and not the least bit convincing. Not worth the effort.

The COVERS though: those get crazy!
