In this fanfiction, it could be that they are sent back in time by an ancient power. When they arrive in the past, they are met with a version of themselves that are much more naive. The kiss might happen as a form of comfort between them, especially when they see the challenges that lie ahead in this different time. This event could set off a chain of events where they have to balance their relationship, their mission to return to their own time, and their desire to fix the past.
Maybe the time travel is caused by a mysterious time - space ninjutsu. In the past, Naruto and Sasuke find themselves in a world where their actions can have a huge impact on the future. The kiss could be a spontaneous reaction to the realization that they are the only ones who truly understand each other across time. As the story progresses, they might try to prevent certain tragedies from happening in the past, all while dealing with their new - found and complicated relationship.
