Do you like spankings? In both sexual and disciplinary contexts? Sometimes both within the same scene? Because that's what you're getting. When I read the description of this book and the author's content warnings I expected a little more variety, especially in the bedroom, but it's entirely spankings. 
If you're lookings for light BDSM to ease you into more taboo types of romance, this is a good place to start. If you're more experienced with BDSM, this feels too repetitive to be really interesting.
