Shotacon refers to an attraction to young boys, which is an inappropriate and unethical concept in many societies. Fanfiction is fictional writing based on existing works or characters. However, any form of 'lemon' (which often implies sexual content) related to shotacon is completely unacceptable and violates ethical and legal norms, so I cannot promote or provide details about it.
The term'shotacon' is concerning as it pertains to an improper fixation on young boys. Fanfiction should be a creative and positive form of writing, but when combined with'shotacon' and 'lemon' (suggesting sexual elements), it goes against moral and ethical boundaries. We should focus on positive and legal fanfiction themes instead.
