I'm not sure if there is such a specific fanfiction. Fanfiction can cover a wide range of themes and descriptions, but this kind of rather odd and inappropriate description might not be common in mainstream Naruto fanfiction.
One common theme is alternative universe stories. For example, what if Naruto was raised in a different village? Another is exploring his relationship with his parents in more depth. Also, there are fanfictions that focus on his training and how he masters new jutsus in unique ways.
As far as I know, this isn't a common theme that has produced well - known fanfictions. Most popular Naruto fanfictions tend to focus on things like character relationships, battles, or alternate storylines. However, that doesn't mean there aren't some out there. You'd have to do a deep search through fanfiction archives to find if there are any that have gained a following for this specific concept.
Yes, in some Naruto fanfictions, he might have a horse. Fanfiction writers often introduce unique elements to the existing Naruto universe, and giving Naruto a horse can be an interesting plot device for adventures or travel within the story.
Well, in Naruto fanfiction involving a female anthro horse, one idea could be that she is a guardian of a certain area in the Naruto universe. Since horses are often associated with loyalty and power, she could be protecting a sacred place or a group of people. She could communicate with the ninja in her own way, perhaps through telepathy or some unique form of sign language. And her appearance might combine the grace of a horse with some human - like features, like having a human - like face on a horse's body but still retaining all the beauty and elegance of a horse.
A common plotline in such fanfiction is the exploration of their relationship further. Since Kushina died when Naruto was young, fanfictions often show them getting to know each other better. It could be something like Naruto learning more about his mother's life before he was born, like her training as a ninja, her friends, and her dreams. And Kushina could get to know Naruto's friends and see how he has created a new family of sorts in the form of Team 7 and the rest of the village.
I'm not sure specifically which 'Naruto is Hung' fanfictions are good. You could try searching on popular fanfiction websites like FanFiction.net or Archive of Our Own. Look for ones with high ratings and lots of reviews.
In a fanfiction about Hagrid, the phrase could be used to describe his loyalty. Just as a horse is known for its loyalty, Hagrid could be said to be 'hung like a horse' in terms of his unwavering loyalty to Dumbledore or his love for the magical creatures he cares for. This gives a positive and family - appropriate spin to the phrase.
Most likely, there may be some inappropriate or non - canon fanfics out there that contain such vulgar content, but this is not in line with the positive and family - friendly nature of the original 'Naruto' series. The official 'Naruto' works focus on themes like friendship, perseverance, and growth.
One possible story could be that the alpha, perhaps a strong - willed character, meets a horse and through some shared experiences, like helping each other during a storm, they become friends. Then their human friend comes into the picture and they all form a special bond. They might compete in friendly races or just enjoy long rides through the countryside.
Well, in canon, Kushina died when Naruto was born, so any interaction between them in fanfiction is non - existent in the original story. In fanfiction, we can see them interacting, like having conversations or going on missions together. Also, in canon, we only get a few flashbacks about Kushina, but in fanfiction, she can be a fully - fledged character with her own story arcs.
