I don't know if there's been an attempt to write an adventure with a succubus in it for 3.0 (or 3.5 for that matter) I know there was one in 2E Night Below. You maybe blazing a new trail here. I think you should stay as true as possible to your original story. Some people may need help descibing an encounter with succubi especially new DM's. You want to create a feeling of eroticism without saying "she touches herself. wink wink nudge nudge"
