Rather than seeking lemon fanfictions, consider those that deal with the themes of justice and resistance in relation to Harry and Umbridge. There are fanfictions where Harry uses his intelligence and the support of his friends to outwit Umbridge. These types of stories can be much more engaging and in keeping with the values of the original series.
I don't really support or promote lemon (explicit) fanfictions as they often go against the intended spirit of the original 'Harry Potter' series. However, if you're interested in non - explicit fanfictions about Harry Potter and Dolores Umbridge, there are many on fanfiction.net that focus on their power struggle within Hogwarts, like ones where Harry and his friends find creative ways to oppose Umbridge's tyrannical rule at the school.
Lemon fanfictions are not in line with the family - friendly nature of the 'Harry Potter' franchise. Instead, you could look for well - written fanfictions that explore the complex relationship between Harry and Umbridge in a more appropriate way. For example, some fanfictions might focus on how Umbridge's actions affected Harry's view of the wizarding world's authority, and how he grew from those experiences.
