This kind of fanfiction is not appropriate. Fanfiction should be a creative way to explore the relationships and stories within the framework of the original work in a positive and respectful way. An 'orgy' theme for these characters is not in line with the family - friendly and positive - value - centered nature of the 'Harry Potter' series, and it is also disrespectful to the fans who appreciate the original work.
One popular story might be 'Forbidden Bonds' which explores a unique relationship between them. It delves deep into their characters and how they might interact in a different way than in the original series. The author creates a lot of tension and drama, making it an engaging read.
Often, it begins with Hermione trying to help Sirius deal with his post - Azkaban trauma. She uses her knowledge and compassion to reach out to him. As he heals, he starts to see her in a new light. Their relationship then grows as they start to understand each other better. The lemon parts usually are used to explore their more passionate and private moments, which are often written in a very tender and intense way, adding a new dimension to their relationship.
Rather than focusing on such improper fanfiction, it's better to explore the positive and official stories in the 'Harry Potter' universe, like Hermione's friendship with the Weasleys in the proper context.
Sure. There are fanfictions that center around the magical adventures in the Harry Potter universe without any inappropriate content. These can include new quests for the trio, Harry, Hermione, and Ron, in different parts of the wizarding world. They might encounter new magical creatures or solve mysteries that were not part of the original books. By avoiding the more adult - themed areas of fanfiction, you can discover a whole world of creative and positive stories.
In a Hermione and Sirius family fanfiction, Hermione might end up marrying into the Black family. Since Sirius was an important part of the Black family before his estrangement, Hermione could find herself involved in the family's complex politics and traditions. She could use her knowledge of magic and her Muggle - born perspective to challenge some of the old - fashioned ideas within the family. Sirius, on the other hand, could be like a mentor to Hermione, teaching her about the more secretive and dangerous aspects of the wizarding world that she might not have known otherwise.
One possibility could be that Sirius sees Hermione's intelligence and determination and decides to take her under his wing. Maybe he realizes her potential and wants to protect her from the dangers in the wizarding world that he has faced himself.
There could be a fascination with power dynamics. Sirius is an older and more experienced wizard in the Harry Potter world compared to Hermione. Fanfic writers may be drawn to the idea of how his knowledge and power could interact with Hermione's intelligence and determination, thus leading to the concept of him dominating in the fanfiction. Also, it might add an element of unexpectedness or novelty to the relationship between two such different characters.
If you're looking for a fanfiction with this specific scenario, you could try using more detailed search terms. For example, include the Hogwarts house Hermione belongs to in the search, or any specific events that might be related to it. Also, look for tags on fanfiction platforms that might lead you to the story you want. There are often tags for characters, locations, and relationships which can help narrow down the search.
