Fanfics that center around Dean and John's joint adventures against supernatural threats without any inappropriate undertones are great alternatives. They can show their teamwork and mutual respect.
Rather than focusing on inappropriate fanfics, you could look for fanfics that feature healthy relationships between the characters, such as their adventures together in a non - romantic and non - inappropriate way.
There are several interesting ones. For example, 'Father - Son Hunting Dynamic' which really explores the unique bond between them during hunts. It shows how they communicate, or sometimes don't communicate well. 'John's Influence on Dean' is another fanfiction that details how John's actions and decisions shape Dean's character. 'Dean's Memories of John' is a more emotional one, focusing on Dean's reminiscences of his father and how those memories impact his present actions.
There are likely fanfics that are more family - friendly versions of the relationship between Dean and Sam. Some might focus on their deep brotherly bond and emotional connection rather than any inappropriate or romantic/sexual relationship. Writers can create stories that highlight their loyalty, shared experiences, and how they support each other in their adventures.
One popular one is 'The Great Game of Love' which beautifully explores Sherlock's internal struggle with his feelings for John. It has great character development.
There is a fanfiction that I remember which was set during a hunt gone wrong. John spanks Dean because Dean made a risky move that could have endangered them both. This story is interesting as it not only shows the immediate situation but also how it affects their relationship in the long run. It delves into Dean's feelings of resentment towards John at first but then how he gradually comes to understand his father's motives as he matures. Another one might focus on a time when Dean was younger and was being trained by John, and the spanking was more about teaching him a lesson in survival rather than just punishment.
One great 'dean winchester love story fanfic' is 'A Hunter's Heart'. It beautifully portrays Dean falling in love with a fellow hunter. The story shows how their relationship develops over the course of various hunts, with the danger and adventure adding spice to their love. It has some really heart - warming moments, like when Dean protects her from a particularly nasty demon.
There might also be fanfiction that delves into their backstories. How they became the characters they are, their families, and their early experiences. These types of stories can be much more interesting and appropriate than inappropriate fanfiction.
Fanfictions that focus on their growth as individuals within the context of their relationship are great. Maybe how Edward's alchemic journey affects his relationship with Winry, or how Winry's skills as a mechanic contribute to their bond.
You could explore friendship - based fanfiction about Ethan and Lena. For example, stories about their adventures together as friends, facing challenges side by side.
In dean - castiel relationship in such fanfiction, there's often a deep emotional connection. They might show a side of extreme vulnerability towards each other. Their relationship can be intense, with a lot of passion and a sense of 'destined to be together' kind of feeling.
