This is inappropriate content as it involves non - consensual and often unethical themes. We should focus on positive, consensual and ethical story themes like love and adventure stories.
I cannot provide relevant answers as it involves adult - related and unethical content. There are many other great story genres to explore, such as mystery or science - fiction.
One common theme is the rescue mission. Usually, there is a hero or a group of heroes who set out to save the kidnapped victim. Another theme could be the discovery of a hidden world during the kidnapping ordeal. For example, the victim might be taken to a magical realm that no one knew existed before.
One common theme is power and control. The kidnapper often seeks to exert power over the victim. For example, in 'The Collector', the kidnapper wants to control the life of the art student he abducts. Another theme is survival. The victim has to find ways to survive in a terrifying situation, like in 'Room'.
One common theme is the power struggle. The kidnapper has power over the victim, and the story often shows how the victim tries to regain some form of control or how the rescuers try to overpower the kidnapper. Another theme is the psychological trauma. Victims usually suffer from mental and emotional distress, which is often explored in depth. Also, the mystery aspect, like finding out the identity of the kidnapper and the motives behind the kidnapping.
One common theme is prejudice. These stories often show how the kidnappers' bigotry and hatred towards the gay community lead to the act of kidnapping. Another theme is the struggle for survival and freedom. The kidnapped gay character usually has to fight against their captors to regain their freedom. Also, there can be a theme of finding acceptance, as the character may face a journey of self - discovery during the ordeal.
One common theme is the feeling of isolation. The kidnapped victim is often alone in a strange and scary place, like an old warehouse or a remote cabin. Another theme is the power struggle between the victim and the kidnapper. The victim tries to gain some control over the situation while the kidnapper wants to maintain dominance.
Well, a frequent theme is the identity of the kidnapper. Sometimes it's an unknown villain, other times it could be a character with a hidden motive. Also, the relationship between the kidnapper and the kidnapped can be explored, such as if there are pre - existing grudges or if it's a case of mistaken identity.
Another theme is the exploration of human nature. We can see how the kidnapped person reacts, whether they are brave or cowardly. And also how the kidnapper justifies their actions. In some stories, the kidnapper may have a complex backstory that led them to commit the crime. In 'The Ransom of Red Chief', we see how the supposed victim, the boy, has a wild nature that challenges the kidnappers' plans, which shows different aspects of human nature.
One common theme is power struggle. The kidnapped person might be a key to power for the vampires, like having a special blood type or ability. Another theme is forbidden love. Often, the kidnapped human and a vampire develop feelings for each other despite the circumstances. For example, in many stories, the vampire may initially see the human as a tool but then fall in love.
One common theme is the rescue mission. The kidnapped character's friends or allies will go on a journey to save them. Another theme could be the psychological struggle of the kidnapped character, like how they deal with fear and captivity in an anime - like setting. Also, sometimes there's a theme of the kidnapper having some sort of hidden motive or backstory that gets revealed throughout the fanfiction.
I don't think it's appropriate to discuss erotic stories. We can focus on positive and healthy literary works such as adventure stories or detective stories.
