Looking for a story or stories in which two best friends (one male, one female) since childhood finally have sex with each other (in late teens or early 20s).
My "Country Boy, City Girl" saga has that.

Two children, basically raised almost as siblings and best friends their entire life realize later that they want to be lovers. In fact, she is the one that finally grows weary of his avoiding this and making the decision that they are together, if he likes it or not.
But it is also not a major part of the series, even though they remain close even after their relationship ends.
