Another movie is 'The Secret Life of Bees'. Lily, the young protagonist, has a complex backstory that involves her mother's situation which could be related to this idea in a way. While not the central focus on her being pregnant herself, her mother's experiences and the secrets around it are important to the plot and touch on themes related to young women and pregnancy in a difficult situation.
One example could be from the novel 'Atonement' where Cecilia's actions and the complex situation she gets into can be seen as a complex tale related to young womanhood and unexpected consequences, though not exactly in the same terms but has elements of young female's life-altering experiences.
No, it is completely unethical. A father has a responsibility to protect his daughter's innocence and well - being. Sharing sex stories with a minor child, especially one's own daughter, is inappropriate and can cause significant harm to the child's mental and emotional state.
Maybe it's a completely new character introduced in the fanfiction. This new character could have some special powers or a unique connection to Naruto that results in the pregnancy.
It could be Beast Boy. Their relationship in the original series has some chemistry, and in the fanfiction, it would be an interesting twist if he were the father. Maybe their relationship takes a new turn when Raven discovers she's pregnant.
In some fanfictions, it could be Gray. Their rivalry - turned - friendship has a lot of potential for such an unexpected plot twist where Gray is the father.
There's a chance it could be a new character introduced in the fanfiction. Maybe someone who has a mysterious past and enters Annabeth's life briefly but leaves a big impact, resulting in her pregnancy.
Or, in a more creative take, it could be a new character introduced just for this fanfic. This new character could bring a whole new set of dynamics and storylines, like a mysterious stranger who has some special connection to Clary.
Perhaps it's a new kind of monster that was created through a combination of human technology and some ancient, unknown force. This new monster mated with Godzilla in some unexpected encounter, and now she's pregnant. There could be a whole backstory about how this new monster came to be and how it interacted with Godzilla.
Most likely, Percy could be the father. They have a strong relationship in the original series, so it would be a natural choice. Their chemistry and shared adventures could be the basis for a story where they start a family together.
