Gray would be extremely angry. He would immediately start looking for clues as to where Natsu was taken. His ice - make magic would be on full display as he might freeze things in frustration while trying to figure out the situation.
One possible plot could be that the kidnappers are from a rival guild who want to use Natsu as leverage against Fairy Tail.

I'm not sure if there is such a specific fanfiction. There are a vast number of fanfictions out there, and while some might explore unique and even out - of - the - ordinary concepts like this, it would take some searching through relevant fanfiction platforms to determine its existence.
Definitely. Some fanfictions might explore their relationship in a more platonic and heartwarming way. For example, they could be on a mission together and have to rely on each other's unique skills. The authors may show how they grow as individuals and as friends through these experiences, rather than taking it in a more adult - oriented lemon direction.
It could be Zeref. Since Zeref has an interest in powerful magic users and Natsu is a strong dragon slayer, Zeref might kidnap Natsu to study his magic or use him in some dark plan related to his quest for immortality or power.
Natsu was walking through the forest one day when suddenly a group of dark mages emerged from the shadows. They quickly overpowered him with some sort of magic -binding spell. They dragged him away to an old, creepy lair. His friends back at the guild soon realized he was missing and set out on a search mission. Happy flew around frantically looking for any sign of his friend. Lucy, Gray and Erza teamed up and followed some leads they found in the forest. They were determined to rescue Natsu no matter what it took.
