What is it that smut fanfiction is called when it's written just for the sex? Oh yes, porn without plot. That's what this feels like for most of the book. Seriously, from the get-go you've got a captured demon king being sexually tortured by some crazy sorceress. Then, when a vampire randomly sets him free, he captures the sorceress and does the same thing to her! Of course, there's a happily ever after, some fighting (must find some way to describe all the sexy male bodies, right?), and a few other characters thrown in for spice, but yeah... Porn without plot.
