There was a furry fox with a rather large butt. This fox was known among the forest animals for its distinctive feature.

It practiced and practiced until it could move faster with its big butt. Eventually, it won a race by using its strong legs and unique balance due to its big butt.
A fox with a big butt lived in a magical forest. This fox's big butt was so big that it left very distinct tracks. One day, a lost little bird followed these tracks and found the fox.

I'm not entirely sure specifically as it's a rather strange and perhaps not a very common fanfiction concept. It might involve some very creative and out - of - the - ordinary ideas related to the character Tails from a particular franchise and an inflation concept related to the butt area, but this is just speculation without actually reading it.

Fanfiction usually takes elements from existing stories and re - imagines them, but this description involves improper items and is not suitable for in - depth discussion.
