Looking for a fic

I am looking for a fic i read the description of but never actually got around to reading, the description was something like.

When training kurama allows naruto to use ma and pa toad's fusion technique when they try it the first time and it has unintended consequences.

The description read like the 9tails was still enemies with Naruto at the time and didn't use its malice to prevent it like in canon.
