I don't think there would be a lot of fanfiction like that. Hinata has always been loyal to Naruto. In the Naruto universe, their relationship is based on a lot of development and mutual understanding. So it's hard to imagine a scenario where Hinata would cheat on Naruto with Boruto in a legitimate fanfiction.
One idea could be to focus on their anticipation and preparation for the baby. They might discuss names, decorate the nursery, and Hinata could be shown getting advice from her family. Naruto, on the other hand, would be excited but also a bit nervous about becoming a father.
Well, there's this fanfiction titled 'Hinata's Influence on Boruto'. It delves deep into how Hinata's gentle nature and strong values shape Boruto's character as he grows. It has some really heart - warming scenes between mother and son. And then there's 'Boruto's Path to Greatness' which also involves Naruto and Hinata in the background, guiding Boruto on his ninja journey.
One idea could be a story where Boruto and Himawari discover an old diary of Naruto's from his early days as a ninja. Hinata helps them understand the context and the values their father held. They then use those lessons to face a new threat in the village.
One unique idea is that Boruto travels back in time to the era when Naruto and Hinata were young. He gets to see their struggles first - hand and understand them better. It also gives him a chance to learn new skills and techniques from the past versions of his parents. Another idea is that Hinata has a secret mission that she has to keep from Naruto and Boruto, which creates a lot of suspense and drama in the fanfiction.
The story could also revolve around the relationship between Naruto and Hinata during this time. They grow even closer as they are about to start a new chapter in their lives. Hinata might teach Naruto some things about their family traditions related to pregnancy and childbirth, and Naruto would be eager to learn. This could be a story full of love, family, and the strength to face any obstacles.
Often, they are shown as more mature and experienced. Naruto is still the strong Hokage but also a loving father. Hinata has become more confident in her role as Naruto's wife and as a mother. For example, she might be more assertive in decision - making for the family.
Websites like FanFiction.net and Archive of Our Own (AO3) are great places to start. They have a large collection of fanfics related to Naruto and his family.
There are many fanfics that explore the relationship between Naruto and Hinata further. Some might focus on their daily family life with Boruto and Himawari, like how they deal with Boruto's rebellious phase while still maintaining a loving family environment.
Well, Boruto might be really embarrassed. He could quickly turn around and pretend he saw nothing. After all, walking in on his parents like that would be quite awkward for a kid.
