Ah, I see! You are "the Succubus"; a demoness that preys on a creature's lust to gain control over them. Your harem, all kept within your "Delight", is made up of many males who desire only for your company and attention. You have many ways of granting newcomers some pleasurable experiences. Your twin brother, the Incubus, also lives in this castle.
I won't keep you any longer. Who knows when someone new may arrive?
