A very common scenario is Draco being protective of Harry during the Hogwarts years. This could be in the form of helping Harry study and protecting him from bullies like the Carrows when they take over the school. Another scenario is Draco using his knowledge of the Dark Arts to protect Harry from Voldemort's followers. And then there are the more emotional scenarios where Draco is there to comfort and protect Harry when he has nightmares or is feeling down about his future.
One common scenario is Draco protecting Harry from other Slytherins who might still hold grudges against Harry. Another is Draco standing up for Harry during dangerous situations in the wizarding world, like when there are threats from dark wizards. And sometimes it's about Draco protecting Harry from the emotional harm caused by the wizarding society's expectations.
One common scenario is in school settings. When other students are bullying Harry or trying to harm him, Draco steps in to protect. Another could be during dangerous magical events. For instance, when a dark magic spell is about to hit Harry, Draco uses his own magic to shield Harry.
Another scenario is during dangerous magical experiments or when they are exploring old, dangerous parts of Hogwarts. Draco, being more familiar with the darker aspects of magic in some cases, will be protective of Hermione who is always eager to learn and might not fully grasp the risks. In these fanfictions, he'll stop her from doing something too risky or help her out when things go wrong.
One common scenario could be when Harry is in danger from other dark forces. Fenrir steps in to protect him, using his own strength and abilities. For example, if there are other werewolves or dark wizards attacking Harry, Fenrir defends him.
One reason could be the complex relationship they have in the original series. Fanfic authors often expand on that. Maybe Draco realizes Harry's importance in the fight against the real evil, like Voldemort, and so he becomes protective. It also adds an interesting dynamic to the story, making it more appealing to readers who love exploring different character relationships.
One common scenario is in a dangerous magical situation. For example, in a battle at Hogwarts, Draco might step in to protect Harry from a dark wizard's spell. Another could be in the face of social threats within the school. Maybe some students are trying to bully Harry, and Draco, having a change of heart, defends him. It could also be that Draco protects Harry from a plot within the Slytherin house that aims to harm Harry due to his fame as 'The Boy Who Lived'.
Sometimes, in these fanfictions, the punishment is related to a competition. Say there's a magical tournament or a Quidditch - related event where Draco believes Harry has cheated or played unfairly. Draco, being the proud Slytherin he is, decides to punish Harry. It could involve making Harry do embarrassing tasks or even trying to get him banned from future competitions.
Well, 'The Green-eyed Monster' is another one. Draco's protective nature towards Harry kicks in when there are threats from the Dark forces. It's a slow - burn romance where Draco's actions to keep Harry safe gradually turn into deeper feelings. The author does a great job of building the tension between them.
One common scenario is during battles. For example, in many fanfictions, when facing dark wizards, Harry positions himself in front of Hermione to shield her from spells. He uses his own body as a physical barrier, showing his extreme protectiveness.
I don't think it's common at all. Fanfiction usually delves into the deeper emotional and plot - related aspects of the original story. Themes like friendship, love, and the fight against evil are much more prevalent. Stealing underwear is such a specific and rather unorthodox concept that it's likely to be a very niche and not commonly found type of fanfiction within the Harry Potter fandom.
No, it doesn't seem to be a common type of fanfiction. Most fanfiction tends to focus on more mainstream themes like relationships, adventures, or character development. The combination of 'draco' and 'vibrator' is rather unusual and not something you'd typically find in the more popular fanfiction genres.
