Be Yourself by Casketbase77

The requests come in, the paintings go out, and the Bits arrive later. That's the shaky system "Rainbow" has managed to work out for herself. A life lived through letters is a little lonely, but she can at least be certain she'll never be seen by someone who recognizes her copypasted face.
You'd think a Rainbow Dash replica would remember that Twilight uses Spike for everything mail related.

Tongue Tried by ambion
https://www.fimfiction.net/
Spike was the strangest of dragons, living his charmed life so far removed from his heritage. Knowing so much. How to be a good friend. How to be a hero.
How to have fun.
But actually being a dragon? Not so much. Barely at all, really.
Ember didn't know what to make of her friendship with the little drake, but she did know two things. Spike needed a teacher, a proper dragon teacher, to show him the way.
And second, that this was going to be fun.
