I don't encourage or promote sexual fanfic content as it often goes against ethical and moral standards. We should focus on positive, non - explicit literary themes.
Power is a frequently explored theme. Succubi often have certain powers, and fanfics may show how they use or abuse these powers. Additionally, the idea of identity is present, as succubi in fanfic may struggle with their identity as demons in a world that may not fully understand or accept them.
One common theme is the seduction. Succubi are often portrayed as alluring creatures that can easily draw men in. Another theme is the idea of a forbidden or dangerous encounter due to their demonic nature.
A common theme is the struggle with identity. As a succubus, Bella is no longer the same as she was. Another theme could be power and its corrupting influence. Since succubi often have powers related to seduction and such, Bella might have to grapple with how to use or not use these powers.
Another theme is the exploration of the supernatural world. Fanfics often describe the world where Catherine as a succubus exists. It includes details about other supernatural beings, the rules of that world, and how Catherine fits into it all. For instance, there might be descriptions of how she interacts with demons, angels, or other magical creatures.
One common theme is the clash of different supernatural natures. Since succubi have their own set of characteristics and so do the Twilight characters like vampires and werewolves, there's often a conflict or a need to co - exist.
Love and relationships can also be a common theme. A succubus may form unexpected relationships with the characters in the Harry Potter world. It could be a romantic relationship, a friendship or a mentorship. These relationships often challenge the traditional ideas of love and connection in the wizarding world. For instance, a succubus might fall in love with a wizard, and they have to overcome the differences in their natures and the potential prejudice from others.
One common theme could be the struggle between Naruto's world of ninjas and the supernatural world of succubi. Maybe Naruto has to deal with the allure and danger that a succubus lover brings into his life.

However, in many succubus - centered fanfics, themes of temptation, the struggle between good and evil, and the allure of the otherworldly are often explored.
