>>52822483The first fanfic I ever read when I was 12 was an Altoshipping fic called "Guardian of the Chosen One" by XD-385. It gets a bit insane with a dark shonen plot where Ash basically discovers he has Goku-esque superpowers (because he's the "Chosen One" mentioned in the Orange Islands), but it's a guilty pleasure that I still enjoy. There's only a couple nsfw chapters sprinkled throughout a much larger story; it takes place during Ash's Hoenn journey, and Ash finds himself missing Latias so much that he decides to go back and visit her in Alto Mare. He and Latias reconnect,
have sex, have two shiny Lati babies, and eventually get married. And I LOVED all of it. I should really re-read it again sometime.
