Esoteric Regret is a horror erotica novella fanfic that takes place in the same world as the Supernatural TV series.
While her parents are away for the night, a nerdy loner infatuated with the occult evokes a powerful demon without the proper binding spell, unleashing the vicious malignance of hell upon herself.
The pornstar shown above, Dillion Harper, is the physical inspiration for this original character. A Google image search will provide more visual aid to those who desire it.
Please note I have only watched the first five seasons, therefore this story does not take into consideration anything beyond that point in the canon.
*** Warning: This is an explicit underage non-con monsterotica. ***
