I don't have any data to suggest that 'big cock harry wolf fanfiction' is popular. It could be a very niche piece of work that only a small group of people are aware of.
Fanfiction that involves inappropriate or vulgar terms is not suitable for promotion. We can focus on positive and creative 'Harry Potter' fanfiction themes like friendship, adventure, or the exploration of different magical elements within the wizarding world.
Since I'm not familiar with this particular 'big cock lord potter fanfiction', it's hard to say exactly. But generally, Potter fanfiction can have a wide range of characteristics. It could be an alternate universe story, where the plot takes a completely different turn from the original books. Maybe it focuses on different relationships between characters or explores new magical concepts within the Potter world.
There's no such story in the original Harry Potter series. However, if we were to imagine, it could potentially be about a large and important magical creature with the word 'cock' in its name that plays a role in the wizarding world. For example, a large rooster - like creature that has some special power or significance, like being able to sense danger and alert the wizards. But again, this is all speculation as it doesn't exist in the real stories.
I'm not sure if there is a specific 'big cock harry neighbor she fanfiction' available. Fanfiction is a vast genre and there are many different works out there. You could try searching on major fanfiction websites like Archive of Our Own or FanFiction.net, but it's also possible that the title you mentioned might be very specific or not commonly found.
I haven't read the 'Big Cock Harry Wolf She' fanfiction. But in general, good fanfiction often takes the existing world or characters and adds something unique.
