Soul Destroyer (mind contro, male-female sex, female-female sex, demonic, incest) by Chrysostomon
Lilith is a demoness who harvests souls for hell.
While the setup was more than familiar, this seemed more like a twisted wish fulfillment plot than demonic tale. That twists together nicely. Fair warning to readers, there’s some bestiality here, but fit with the rather extreme story. Ultimately, this was a shocking, incredibly vivid supernatural horror of a tale. It was like serial recruitment, but without that mindless drone army or cult. An interesting, quick, pure story.
