In some fanfictions, it could be a miscommunication situation. Sam might think he's doing the right thing in a hunt, but John disagrees. So, John spanks Sam not just as a punishment but also as a way to make him see his perspective. Also, it could be related to Sam's relationship with the supernatural side of himself. John might be trying to keep Sam's human side dominant by using this rather extreme form of discipline.
Yes, there could be. A fanfiction with such a plot might show Sam learning from the experience and becoming more cautious in his actions. He might grow to respect John's authority more, leading to a change in their relationship dynamics.

Some fanfictions explore a romantic relationship between Sam and Bela. Given their different personalities and backgrounds, it makes for a complex and often angst - filled relationship.

One popular storyline could be a magical or cursed situation that causes one of them to become pregnant against the normal laws of nature. For example, a spell gone wrong in a hunt that has unforeseen consequences. Another could involve some sort of alternate universe where male pregnancy is the norm and Sam and Dean have to navigate this new reality while still dealing with their usual hunting duties. And sometimes, it might be a really out - there concept where they are impregnated by some sort of otherworldly being as part of a deal or a plot to either save or destroy the world.
Some Tumblr blogs might also have links or even host 'Supernatural' fanfictions. You can search for 'Supernatural fanfiction' or the specific relationship tags on Tumblr.

One interesting storyline could be the baby sister having special powers that she has to learn to control. Maybe she can communicate with spirits in a unique way, different from Sam and Dean, which adds a new dynamic to their hunting adventures.
One possible storyline could be that Sam is influenced by a new, mysterious character in town. This character might be using some sort of mind - control or persuasion power on Sam, making her act out of character and cheat on Danny.
