Just finished the first volume and my honest impression is, this book starts at least half decent and with a promising setting but after some point it gets to the point where it's best described as the two protagonists are in heat but on a leash.
At this point it becomes pretty vulgar and agonizing to read for myself - for some this might satisfy their fetish but I doubt the majority would enjoy this.
After all even the antagonists are totally depraved whereas this description seems like an euphemism.
