In the fanfic, the cock cage could make Petunia feel a sense of responsibility. Maybe she realizes that she has to keep it away from Dudley or Vernon, and in doing so, she starts to show a more protective side. This could lead to her developing a new understanding of Harry, who has always been in a world full of strange and potentially dangerous things. She might start to see him as a person who has had to deal with a lot, just like she has to deal with this strange object now.
In a non - offensive and family - friendly fanfic idea, perhaps Petunia Dursley discovers a magical cock cage (not in a vulgar way) that has some connection to the wizarding world. Maybe it was left by a wizard who visited Privet Drive by mistake. Petunia, being the nosy character she is, tries to figure out what it is and how it works. This could lead to a series of comical events as she fumbles with this strange magical object, all while still maintaining her strict, Muggle - like personality.
By focusing on their shared past traumas. For example, both have had experiences related to Lily's death in different ways. Harry lost his mother, and Petunia lost her sister. They could start to bond over this common pain and gradually move towards a more positive relationship.
A fanfic could connect them by having a toy that was passed down from Lily Potter to Harry, but Petunia has kept it hidden all these years. When Harry discovers it, it causes a big conflict as Petunia doesn't want to let go of the last piece of her sister she has in that way. But eventually, it could lead to a moment of reconciliation between them.
I hope not. 'Harry Potter' is a family - friendly franchise, and creating fanfics with such inappropriate and vulgar content goes against the spirit of the original work. J.K. Rowling has created a magical world full of positive values, and we should focus on positive and creative fan - made works.
In a more comical plot, the lemon could be a mischievous magical object that keeps causing chaos in Petunia's house. It might make things float or turn into strange creatures. Petunia, being the uptight person she is, has to deal with this lemon - induced mayhem while also trying to keep up appearances in front of the neighbors. This could lead to some really funny situations and a change in her attitude towards the strange and magical over time.
One possible fanfic could be about Petunia Dursley finding a magical toy that once belonged to Harry Potter's parents. Maybe she discovers it in the attic and it starts to show her memories of Lily and James Potter. She realizes that she has been wrong about Harry all along and decides to change her attitude towards him.
In some fanfictions, Petunia's character develops from being a cold and resentful aunt to a more understanding and protective figure. For instance, when she learns more about the wizarding world's threats to Harry, she starts to see him as more than just an unwanted burden.
There are indeed appropriate fanfics. Some may center around Petunia Dursley's early life and how it influenced her treatment of Harry. It could be about her jealousy of Lily's magic and how she eventually comes to terms with Harry's presence in her life in a way that is more about family drama and less about anything inappropriate.
Petunia Dursley is significant as she represents the non - magical world's reaction to magic in the Harry Potter series. She is a Muggle who has a complex relationship with the magical world. She has seen magic through her sister but resents it. Her actions towards Harry, like treating him as an outcast in her home, show how some Muggles might fear or be envious of the magical abilities they don't possess.
I'm not sure specifically about a fanfic involving Petunia Dursley and a lemon in the Harry Potter universe. However, there are countless Harry Potter fanfics out there, so it might exist.
