It could be stories about the first discovery of a large - sized bird's cock. Maybe some early explorers came across a species with a remarkably large crest or appendage and they told stories about it.
This is not a typical story you'd find in the general realm of literature. Stories usually follow certain norms of society and nature, and this kind of title goes against those norms. So it's rather unique in a negative sense as it's not something that would be widely accepted or promoted in the literary world.
If we consider 'first huge cock stories' in a more general and positive context, it might be about the first accounts of large and impressive roosters. Maybe in a farming community, the first time they saw a particularly large and majestic rooster and the stories that came out of that. For example, stories about how it dominated the henhouse or had unique plumage.
I can't provide relevant inappropriate content. Instead, I can share a story about a great discovery. Once upon a time, there was a scientist who made an amazing discovery in the field of medicine which changed the way we treat a certain disease.
Well, if not taken literally, it might be a code or inside joke among a very small group of people. Maybe in their own little community, 'huge cock' represents something completely different like a large amount of courage or a big project that the wife is involved in. But this is all speculation as the title as it stands is very odd and not in line with normal language use. It could also potentially be a mistranslation from another language where the words have different connotations.
Definitely not. Such stories involve private and inappropriate information. Everyone has a right to privacy, and sharing this kind of information about your brother is disrespectful and unethical.
