In a Naruto riding Kiba fanfiction, it could be a really strange yet interesting scenario. Maybe Naruto is on Kiba's back for a race in the forest. They could be competing against other teams from the Hidden Leaf. Naruto might be using Kiba like a mount to get an advantage in speed.
Perhaps in this fanfiction, there is some sort of magic or jutsu involved. For example, a new jutsu has been cast that temporarily bonds Naruto and Kiba in a way that Naruto has no choice but to ride on Kiba. This could lead to them having to work together to break the jutsu and in the process, they learn more about each other's skills and abilities.
One possibility is that it's part of a prank. Naruto and Kiba are friends, and Naruto might have dared Kiba to let him ride on his back. It could be a humorous situation where they are trying to avoid getting caught by Shikamaru or Iruka sensei while Naruto is perched on Kiba.
A simple idea could be that Naruto and Kiba are on a mission together. Naruto injures his leg, and Kiba offers to let Naruto ride on his back to get back to the village faster. Along the way, they encounter some small enemies and have to fight while in this unusual arrangement.
Kiba could end up having a whole new set of skills or abilities as a girl. In the Naruto world, different genders might have different natural affinities for certain types of jutsu. So, as a girl, Kiba could discover she has a better connection to, say, healing jutsu or some other form of ninjutsu that she didn't have before. This could be really interesting as it would change her role in the team and in the village.
Kiba might immediately take Naruto to the nearest medical ninja. In the Hidden Leaf Village, there are always medical ninjas on standby. Kiba's quick action could save Naruto from a more serious condition.
Well, they might face a lot of challenges. Since they are both ninjas, their active lifestyles could be a problem during pregnancy. They would have to be careful not to overexert themselves. Also, there could be rumors and gossip in the village about their relationship and the pregnancy.
A fanfiction could be about a race. Naruto, Hinata, and Kiba enter a village - wide race. Naruto is confident in his speed and agility. Hinata is determined to prove herself. Kiba, with Akamaru, thinks they have an advantage. The race has different obstacles like rivers and trees. Naruto might use his shadow clones to get through some parts faster. Hinata could use her gentle fist to jump higher over obstacles. Kiba and Akamaru could use their tracking skills to find shortcuts. In the end, it doesn't matter who wins but the lessons they learn about themselves and each other during the race.
Perhaps it could be about a competition between Naruto and Kiba during a particularly intense training session. They both get really 'in the zone' or 'in heat' in terms of their competitive spirit. Naruto might be using his new jutsu while Kiba is pushing Akamaru to their limits. This could lead to some friendly rivalry and growth for both of them.
It could be that Kiba has been involved in something that Naruto considers wrong. For example, if Kiba endangered the safety of the village or their friends, Naruto, being the protector - type, would take action against him. Or perhaps there was a misunderstanding between them. Kiba might have been framed for something, and Naruto, believing the false information, tries to 'destroy' Kiba in the heat of the moment.
A misunderstanding is also likely. Maybe Kiba overhears a conversation that he misinterprets. For instance, he might think Hinata is talking badly about him when in fact she is just discussing a general ninja problem. This could make him angry enough to hurt her, either with words or actions.
One possible plot could involve a love triangle where Naruto is initially interested in someone else, but as he spends more time with female Kiba on various ninja tasks, he starts to have feelings for her. Meanwhile, female Kiba might be hesitant at first due to Naruto's reputation or her own focus on being a strong ninja. As the story progresses, they have to overcome challenges like rival ninja clans and internal doubts to be together.
Well, Draco might be a bit nervous at first. Lucius could start by showing him the basics, like how to hold the reins or the broomstick properly. Then they could move on to more advanced things.
