Black on Blonde (Serena Troy #1)

Sex is her life — at least it's her job. Serena Troy is a powerful witch who has dedicated her life to protecting humans from supernatural sexual predators. When she meets an evil witch who matches her powers, Serena has to pull out all her tricks to rescue a human sex slave from a hell dimension.

It begins with a sex spell and an orgy but Serena gets a novice trainee who lets the witch escape. With the help of a sexy changeling, Serena must combat the residue left by the sex spells, which leaves them sexually crazed at every turn. It's up to her to rescue the human while she protects others from the evil witch out to fulfill her own fetish.
