Not my kind of book. My penchant for romance and erotica is entirely character-based. Kinky or not, I have to connect to the main character(s).This is not a character-driven story. The MC has no back story, no flaws, no mentioned family, no motivations. She's simply a vehicle used to demonstrate BDSM instruction. The sex scenes are technical and classroom-style, not passionate. There are no memorable quotes or thought-provoking moments. Just a lot of sex.Some might find this enjoyable. It just wasn't for me, so I'm not going to rate it.
