Hey, Being Raped Is Turning Me On!!
It that theme doesn't bother you, then you'll find this story pretty enjoyable. It's not really D/s or bdsm, so much as an exchange of power in a few very descriptive dub-con encounters.
I wouldn't want to encounter a cop like Brendan or a doctor like Stephen in real life - would find them creepy as hell and ethically bankrupt, but in the context of the story, they're perfect for each other.
Really, it gets 4 stars mainly for the well-written sex scenes.
