There's not enough information in just that title to really know what the story is about. It could be a prank or dare - related story where the 'big cock' might be some sort of object or task that's named in a rather strange way. Maybe it's a local or niche story within a particular group.
No. It doesn't sound like a common type of story at all. The title is very unusual and not something that you would typically come across in mainstream literature or storytelling.
I'm not entirely sure specifically what the 'big cock challenge' is in Percy fanfiction. It could potentially be some sort of made - up, humorous or very specific in - universe challenge created by the fanfiction author. However, without reading the relevant fanfiction, it's difficult to be more precise.
Well, the 'big cock alphabet challenge' in Percy fanfiction could potentially be a fan - created concept. It might be a challenge where authors have to write something related to Percy, for example, using each letter of the alphabet to describe a character trait, an event, or an object in the fanfiction world.

One possible consequence is the end of the relationship. Once the partner discovers the cheating, it's hard to regain trust. Another consequence could be a lot of emotional pain for both parties. The partner who was cheated on will feel betrayed and heartbroken, while the girlfriend might also feel guilty later.
Cheating is an unethical behavior. However, if we assume such a story, perhaps the girlfriend met someone who seemed more exciting to her. But this is not acceptable in a committed relationship. In a healthy relationship, loyalty and communication are key. If there are problems, they should be addressed openly rather than turning to cheating.
