An eccentric man from time to time takes a mistress, keeping her in his fortress like mansion estate. He expects her complete loyalty, and provides all her worldly needs. She's allowed to have anything her heart desires, at least material-wise, but isn't permitted to leave the estate or have company over without his explicit permission.
The man is young and powerful, yet rumored to be far older than he actually appears to be. Each mistress serves for a time of her own choosing, predefined at the beginning of her service. However, he's recently put out a request for a lifetime mistress. A woman who will serve in his bed and at his needs for as long as she lives.
Rumors from mistresses who have served him before include a desire to keep his mistresses as virtual pets, often without clothes. It's also rumored that he has a very high sex drive, having sex with his mistress quite frequently. Like his mistress, he hardly leaves the estate, being a recluse.
Who will become his newest mistress, will you take the challenge and serve for pleasure?
