One possible fanfiction could be about how Naruto, in his fox - like form, and Hinata as a bunny, meet in a magical forest. They might initially be wary of each other, but as they start to communicate, they find common ground. Maybe they team up to protect the forest from some external threat.
The plot could be that Naruto, in his fox form, gets lost in a strange land where Hinata, as a bunny, is the local guide. She shows him around, and they start to bond over their shared love for nature. As they explore, they discover an ancient mystery related to their two species and must work together to solve it.
In the fanfiction, Naruto could develop his emotional side more. As a fox, he may have been more focused on physical abilities, but through his relationship with Hinata, he starts to explore his feelings. Hinata can develop her leadership skills. Suppose there's a situation where they need to lead other animals to safety. Hinata, with her gentle but determined nature, steps up and Naruto supports her. This helps both of them grow as characters and strengthens their relationship.
Fox Naruto would likely be mischievous, like a real fox. He might be quick - witted and always ready for an adventure. His loyalty would be unwavering, especially towards Hinata. Bunny Hinata, on the other hand, would be gentle and kind. She might be a bit shy, but also very brave when it comes to protecting those she loves.
Another plot could be that Hinata, as a bunny, discovers Naruto's fox form by accident. At first, she's a bit scared but then realizes Naruto is still the same kind - hearted person. They then start a journey to discover the secrets of Naruto's fox heritage and along the way, they face challenges like a group of hunters who are after Naruto. Through their adventures, their bond grows stronger.
A third plot idea is that there is a festival in the village that only those with animal forms can participate in. Naruto and Hinata enter as a team. They have to compete in various games and tasks. During this time, Naruto realizes his true feelings for Hinata as he sees how kind and strong she is, even in her bunny form.
A common theme is the exploration of Naruto's unique connection to the fox and how it impacts his relationship with Hinata. For example, his fox - like strength might make Hinata see him in a new light.
One possible plotline could be that Fox Naruto has some unique powers related to his fox form that play a role in his interactions with Futa Hinata. Maybe he uses those powers to protect her in a dangerous situation.
I'm not sure specifically about 'lemon' fanfictions as they often involve inappropriate content. But there are many great Naruto and Hinata fanfictions that focus on their relationship development, like those exploring how Hinata's love for Naruto grows over time and how Naruto finally realizes his feelings for her.
Their relationship could develop through shared experiences of dealing with the demon fox. For example, Naruto might open up more to Hinata about his fears regarding the fox, which would bring them closer.
