A 'jon x sansa lemon fanfic' might be characterized by its exploration of the physical aspect of their relationship. However, this is a rather niche and often frowned - upon type of fanfic due to its adult - themed nature. In a more positive light, if written well, it could also delve into the deep emotional bond between Jon and Sansa and how that translates into a more intimate relationship, but still, it's not a mainstream or family - friendly type of story.
