If the narration is first-person, the story is first-person. And generally it's always assumed that the story is being told for a reason, and is being told to another party, especially when the narration is done in an oral style like yours. That other party may be implied, or may be revealed fully through the narrator's voice, or may be left totally ambiguous. But a first-person story is always being told for a reason: there is another party whom the reader assumes the role of during the telling of the story. I give a good example or two in my Tips For Writing Epistolary Fiction blog post here and on my website.

I can use a few of my own works as examples of this, but there are some SPOILERS involved, so reader beware.

Jozsa's Grove is narrated by Brad the ex-soldier to a friend named Jerry and several other unnamed persons, and he implies that he's doing so from an insane asylum. He's recounting the story so they'll realize why he did what he did and hopefully let him out.

Likewise The Portrait of Noelle Dumont is told in a series of documents: it's mostly first-person, but the narrator changes periodically, sometimes changing to third-person news headlines. At the end it is revealed that Noelle's friend Aubrey has caused Noelle's suicide and collected the documents as mementos, and plans to read them one more time before burning them all. So in the end, there are several narrators, but the reader assumes the role of Aubrey.
