Thorki + rain fic search
Looking for a fic where they are on Earth and the Avengers need it to rain for some reason (drought, fire, etc.) and ask Thor to bring a thunderstorm. But I guess Thor's god of thunder & god of fertility powers are linked so that he is only able to create rain when he is having sex. So he tells the team that he needs Loki to help with the magic and they need total privacy. Not their first time and they do this several times until Loki is injured but they still need rain so the members of the Avengers ask if they can help, not knowing what it actually entails and Thor refuses.
