In this fanfiction, perhaps Peter Parker is a huge dragon fan from a young age. One day, he somehow gets transported to a world full of dragons. There, he uses his intelligence and Spider - Man - like skills to survive. He might learn how to communicate with the dragons and ends up befriending one. This dragon could then help him get back to his own world, but not before he has to face some challenges in the dragon world, like saving the dragon eggs from poachers.
Well, it could be a story full of adventures where they fight crime together as a married couple. Maybe they'd have a secret base in their shared apartment where they plan their superhero strategies while also dealing with normal married life stuff like who does the dishes.
