There are a few out there. However, the 'Black Dagger Brotherhood' series by J.R. Ward also has some paranormal elements that are intertwined with passionate relationships. The vampires in this series have their own complex society and love lives which can be seen as having an erotic aspect at times.
One could consider 'The Immortals After Dark' series by Kresley Cole. It has a blend of different paranormal creatures like werewolves, vampires, etc. The relationships between the characters are often intense and include elements of sensuality, which are characteristics often found in paranormal erotic novels.
One popular erotic paranormal novel is 'Fifty Shades of Grey' which combines elements of a romantic relationship with some rather intense sexual themes within a modern setting, though it's not strictly pure paranormal. Another could be 'The Vampire Diaries' series of books which has some romantic and sensual undertones between the characters within the vampire - filled paranormal world.
One popular one is 'A Discovery of Witches'. It combines elements of the paranormal, like witches, vampires, and daemons, with a strong romantic plot. The relationship between the main characters is filled with passion and mystery.
'Black Dagger Brotherhood' series also has elements of this genre. It has a dark and brooding atmosphere, with the male characters having paranormal abilities. The romances in these books are intense and often include erotic undertones as the characters struggle with their feelings and the dangerous world they live in.
One popular 'erotic paranormal romance novel' is 'Fifty Shades of Grey'. It combines elements of romance and a bit of the 'paranormal' in the sense of the complex and somewhat mysterious relationship between the main characters. Another is 'Twilight', which has a paranormal aspect with vampires and werewolves, and also has elements of romance that some might consider to have an 'erotic' undertone, especially in the intense relationships between the characters. And 'The Vampire Diaries' books also fall into this category, with the allure of the vampire characters and the passionate relationships that are filled with both love and danger.
I'm not sure about the popularity of online paranormal erotic short stories as such content is not in the mainstream and may not be widely promoted due to its inappropriate nature in many contexts.
Rather than seeking out paranormal erotic stories which may not be appropriate, you could explore normal paranormal stories which can be found on platforms like Wattpad or Goodreads. These offer a wide range of tales that are engaging and family - friendly.
Most platforms and communities also do not allow the sharing of this type of content due to its improper nature.
The difference lies in the level of sensuality and sexual content. While a normal paranormal novel may have a romantic sub - plot, it's not the main focus. In an erotic paranormal novel, the sexual attraction and relationships between the characters are a major driving force of the story. For instance, in a regular paranormal about fairies, the story could be about their magic and their role in the ecosystem. But in an erotic paranormal with fairies, there would be more focus on their sexual desires, mating rituals, and the passionate relationships that form within their fairy society, often with detailed and steamy descriptions.
The unique aspect of paranormal erotic novels is the combination of the supernatural and the sexual. It takes the unknown and often dangerous elements of the paranormal world, like vampires or werewolves, and pairs them with human or otherworldly characters in passionate relationships. This creates a sense of mystery and excitement that regular erotic novels may lack.
One common theme is the supernatural beings' allure. Vampires, for example, are often depicted as extremely attractive and seductive in these novels, which adds to the erotic aspect. Their immortality and power make them both dangerous and exciting.
