There are many succubus series such as the Latex Succubus, and Feminine Succubus Seed. However, if these do not suit your needs, this addition to the Succubus Harem series of files is for meditating on your own externalization of certain fetishistic and self-improvement needs. A simple walkthrough for your own succubus, from the ground up. First, imagine the succubus in question- a dreamlike figure, envision name, meditate on her mannerisms, style of dress, interactions with any other succubi you've installed.
Something made from your own mind and thoughts will always be more satisfying, after all, though you may lack the ability to articulate what you should think about as accurately as some of the more descriptive succubus files. Give it a listen, think of it as an opportunity to externalize impulses normally kept solely internal, derive new perspective, and perhaps a new purring feminine voice in your ear.
This file makes reference to concepts from Mental Mansion and from Summoning Circle, so make sure you've tried those.
