Virgin
If you search the "Erotic Horror" tag about half are in fantasy. You could also lean into whatever the the dominant sexual theme of the story is going to be.
Hell of a Party
A succubus escapes from hell during Halloween and is mistaken for someone in a (slutty) Halloween costume. What better place to go than a student party with drunk and promiscious young men and women to feast on? (The same concept works with a vampire or even a ghost possessing someone.)
EDIT: Especially the ghost possessing someone works because you can go all in on "their eyes have gone full pupilless white and their skin is sickly pale, but people just think those are cool contact lenses and makeup" category.
I might try to write it.I would like to see this concept become an actual story maybe in the spooky seasons Halloween Competition of 2026.
This is NOT in the funeral etiquette!
As the family and servants gather for the funeral of dearly beloved (cruel tyrant) Countess Evgenia Chernysnov (mainly they are just making sure that the old bitch is finally dead and that the next generation can put their claws into her vast riches and territories), they are shocked to see her rise from the coffin looking very alive, and also extremely horny.
The shock of this miracle is replaced by confusion and then lust as she countess celebrates her revitalisation by giving her loving touch and offering her body to those present. At first they don't even notice the guards blocking the doors to the church from outside but as the orgy reaches a climax, some have maintained enough composure to notice that the Countess is draining more than just cum from her companions. They are too late to flee nor can they resist the hypnotic gaze of their mistress who suddenly seems much younger and buxom than she had before.
Not yet, maybe one day.Only if I also had the energy to write them out.
