One common theme is the exploration of power dynamics. When Draco bites Harry, it can represent a shift in power, either Draco asserting himself in a new way or Harry having to deal with a new vulnerability. Another theme is the idea of forbidden love. The biting could be seen as a very physical and somewhat violent act that still has an undercurrent of attraction between them. It's like they're breaking the rules of their normal relationship in Hogwarts.
It might be for the sake of exploring unique and unexpected interactions between the two characters. Their relationship in the original books is complex, and this is a very different way to add a new dynamic.
One interesting story could be where Draco bites Harry out of a moment of extreme anger during a duel, but then realizes the severity of his action and tries to make amends. This could lead to an unexpected friendship between them.
One popular fanfic with this premise is 'Draco's Dark Desires'. It delves into the complex relationship that forms between Draco, as a vampire, and Hermione. The story is filled with tension as Hermione tries to understand her new situation and her feelings for Draco. Another is 'Vampire Draco's Bite'. It has a more action - packed plot where they have to face various challenges together after the bite.
A possible plotline could be that after Draco bites Hermione, she starts to develop some vampiric traits herself. This causes a stir in the wizarding world and they have to go on the run together. Another could be that Draco bites Hermione as part of a dark ritual, but then realizes he has feelings for her and tries to reverse the effects.
One great 'Harry and Draco' fanfic is 'All Our Secrets Laid Bare'. It delves deep into their complex relationship, exploring how they might interact outside of the typical Hogwarts rivalries. The story is well - written, with vivid descriptions of the wizarding world. Another one is 'The Boy Who Only Lived Twice'. It takes a unique spin on the characters, showing a more vulnerable side of both Harry and Draco. There's also 'A Thin Line' which focuses on their forced cooperation in a dangerous situation and how it changes their perception of each other.
I'm not sure if there is an existing 'Harry Spanks Draco' fanfic. Fanfics cover a wide range of themes and pairings, but this particular one might be quite rare or not widely known. You could try searching on popular fanfic websites like Archive of Our Own or Fanfiction.net, but be aware that such a title might also imply non - consensual or inappropriate content which is not acceptable in many communities.
One great Draco Harry fanfic is 'All Our Secrets Laid Bare'. It really delves into the complex relationship between Draco and Harry in a way that's both believable and engaging.
There are many 'Draco Saving Harry' fanfics out there. Some explore the idea of Draco having a change of heart due to a shared danger they face, like a dark wizard threat that only they can overcome together. It's interesting to see how the author builds the trust between them in these stories.
I recommend 'A Different Kind of Savior' where Draco uses his knowledge of dark magic to save Harry from a death - eaters' trap. It's a short but intense read.
