One way could be to make it a comical misunderstanding. For example, Harry is forced by a magical prank gone wrong to 'suck' on a lemon drop that Snape always has, and it's all just a big, silly situation that makes for a humorous moment between their otherwise tense relationship.
This could potentially be a very dark and forced power - dynamic exploration in a non - sexual way. Maybe it's about Harry being forced by some dark magic or a plot device to perform an act that goes against his will towards Snape, symbolizing the complex and often adversarial relationship between them in the original series.
This is completely inappropriate. Fanfiction should be about exploring characters in a way that is in line with basic human values. This kind of description goes against decency and respect, and it is not something that should be part of any fan - based creative writing.
Harry would probably be quite resentful at first. He might think Snape is just being his usual unfair self. So, he would be sulky and do the tasks reluctantly.
One negative impact is that it spreads immoral and vulgar ideas. It can also make the original work's fan community look bad as it goes against the positive and creative nature that fanfiction should have.
One reason could be a misfired spell by another character. For example, if a young wizard was experimenting with a transportation spell and it backfired, it could accidentally force Harry to be attached to Snape in this 'ride' situation. Another reason might be a plot by a dark wizard who wants to see chaos at Hogwarts. They figure that forcing Harry and Snape together in this strange way would disrupt the normal order of things.
Obviously, Harry Potter and Severus Snape are the main characters. Harry is the one who is forced into this situation, and Snape is the one he has to please. But other characters like Hermione and Ron could also be involved. They might try to help Harry out of this difficult situation or be affected by the consequences of Harry's actions to please Snape.
Perhaps in the fanfiction, Harry is magically bound to please Snape in academic tasks. So, he has to study extra hard in Potions class and other subjects Snape is involved in. This might result in a transformation of their relationship, from animosity to a grudging respect as Snape starts to see Harry's efforts.
Yes, it's possible. Fanfiction can take many different turns. Some writers could be exploring the idea of forced proximity between Harry and Snape to build a different kind of relationship dynamic. Maybe it's about Harry being magically or situationally forced onto Snape's bed as a means to start a conversation or resolve some long - standing misunderstandings between them, without any improper undertones.
Well, Harry could be forced to clean the Potions classroom during detention. Snape might make him scrub every cauldron by hand while muttering about how clumsy Gryffindors are. Harry might accidentally spill a potion ingredient, which makes Snape even angrier and gives him more tasks to do, like sorting out all the potion ingredients in the store cupboard.
