I am trying to find a old story I have only half-way read though, I am sure it is a mature story where Princess Luna invites Applejack, Big Macintosh, and Apple Bloom to a secret island for some R&R, the total characters in the story are the first four I said and a single male thestral(Bat-pony). Also this story is anthro, along with due to the first part is where Applejack and both her big brother and little sister find out that all their clothing has to be detained due to the nobles wanting to find the island and see what's on it, besides that and both Luna and big mac falling in love, that's it.

Also I don't need to know the storys name right now due to my reading the rest of the Nyx stories' so please take your time.
