Yes, there might be some fanfictions with this theme that are written in a non - explicit and family - friendly way. However, it can be a bit hard to find as the concept might seem a bit unusual at first. You could try searching on fanfiction - dedicated websites and filtering for appropriate ratings.
Fanfiction.net could also be a place to search. However, be aware that the content there can vary widely in terms of quality and appropriateness. When you search for 'Stiles gets spanked' on this site, you should read the summaries and reviews of the stories before actually reading them to make sure they are what you are looking for. Additionally, some smaller, fandom - specific forums might also have relevant fanfictions, but they can be harder to navigate and find what you want.
Definitely not. Even in the context of fanfiction, the concept of spanking between characters can be considered offensive or at least not suitable for younger or more sensitive audiences. There are likely themes and actions that go against common standards of propriety.
Perhaps in this fanfiction, Stiles has disobeyed Peter's orders which were crucial for their safety or the safety of others. Peter, being frustrated and feeling responsible, resorts to spanking as a way to show his extreme displeasure. But this kind of plot would also need to deal with the aftermath, like Stiles' reaction of anger, hurt or maybe even understanding, and how it affects their relationship moving forward.
Well, often in these fanfictions, Stiles becomes more confident. His physical appearance might also change, like he could start dressing better or have a new haircut that gives him a 'hot' look. For example, he might start wearing more stylish clothes that show off his personality.
It could be his love interest, like I mentioned before, Lydia. She might reject him because she's too focused on her own goals or perhaps she doesn't see Stiles in that way at the time. Their relationship has always been a bit complex in the show, so this would be a likely scenario in fanfiction.
His relationship with his friends would likely become more strained. They might be afraid of him or he might be afraid of hurting them. For example, his best friend Scott, who is also involved in the supernatural world, might be worried about Stiles losing his humanity.
The fanfiction could be about the adventures Stiles and the puppy have. They could go on hikes together in the forest near his town. During these hikes, they might encounter strange things or other supernatural beings. The puppy could either be scared or curiously investigate. Stiles would have to protect the puppy and also figure out how to deal with whatever they come across.
Yes, there might be such fanfiction out there in the vast world of fan - created works. However, this kind of story often takes a rather unorthodox and perhaps controversial approach to the characters. Fanfiction can cover a wide range of themes and interpretations, but this one is likely to be quite different from the typical Harry Potter stories we know.
