Think about using lemons as a plot device for family traditions. Say, every year they make lemon pies for a special family gathering. The story could detail their preparation, the mishaps along the way (like too much lemon juice in the filling one year), and how they always manage to create a delicious pie in the end. This shows the family unity and the role of lemons in their family story.
You could write it as a series of vignettes. Each vignette features a different encounter related to lemons. Maybe one is about a lemon tree they planted together in the backyard. The daughter watches as the tree grows over the years with her father's guidance. It's about the passage of time, growth, and the father - daughter bond, all with lemons as a backdrop.
Focus on the relationships rather than any romantic or sexual aspects. For example, a story could be about a lesbian mother raising a daughter. The story could revolve around the mother teaching the daughter values, and the daughter learning about acceptance from her mother. It could also include how the mother's relationship affects their family dynamics in a positive way.
Fanfics that involve inappropriate or improper relationships like 'dad and daughter' in a romantic or unethical context are not acceptable, so I can't recommend any. We should focus on positive, healthy family - centered stories in fanfic literature.
You can focus on the friendship aspect between Peter Pan and Wendy. For example, they could go on a lemon - hunting adventure in Neverland, just to make some delicious lemonade for all their friends. The lemons can be a symbol of something positive like joy and sharing.
Another way is to have it be a story about a magical object. Let's say there's a magical flower in the school garden. When the teacher touches it, she starts to show signs of pregnancy, but it's really just a magical test. The students and the teacher then have to go on a quest to find the antidote. Along the way, they learn about teamwork, respect for elders, and that things aren't always what they seem at first glance.
A father taking his daughter to her first dance class. He waits outside for her, and when she comes out all excited, he gives her a big hug. It shows his support for her new interest.
We can focus on the more innocent aspects of the diaper, like it being a cute accessory for a baby character. And the 'lemon' can be a simple flavor of a drink or a scent in a garden that the characters enjoy. Avoid any inappropriate or adult - like themes.
Family - friendly 'animal lemon fanfic' can be created by emphasizing positive values. Have the animals work together to solve a problem related to the lemon, like finding a way to share it equally. You can also add a touch of magic in a very innocent way, like the lemon having the power to make the forest more beautiful for a day. Keep the language simple and the story line straightforward so that kids can easily follow along.
The concept could be reimagined as Naruto being adopted in a sense by the spirit of the Kyuubi. They could form a family - like relationship where the Kyuubi, in a female form, acts as a guardian or guide for Naruto. She could teach him special ninja techniques that are unique to the Kyuubi's power but in a very positive and clean way.
In the movie 'Moana', Moana's father, Chief Tui, has a relationship with her that evolves. Initially he is protective in a more traditional way, but as the story progresses, he comes to understand Moana's calling. This shows a family - friendly exploration of a father - daughter relationship.
It could be rewritten as a story where Jasmine is on a quest to expose Jafar's wrongdoings and restore peace to her land. This way, we shift the focus from any inappropriate implications to a more family - friendly adventure story.
