The Castle has operated for hundreds of years at various locations around the world. A club built around all human desires and run by a family of succubi, the Castle now resides in the City of Angels in sunny, Southern California. After thousands of years alone, Eva's brothers are determined to find her a mate whether she wants one or not and, after getting recently her heart broken, she definitely doesn't want to. Fortunately for Eva, her brothers are adept at getting her what she needs, not just what she wants... in this case Cassie, a bold sub looking for a mistress.
