This statement is inappropriate and unclear. It could potentially be a very strange or misphrased expression. Maybe it's some sort of made - up or inside - joke within a specific context that we're not aware of.
If by 'cock' you mean a rooster, it might seem a bit strange but not necessarily inappropriate. However, the way the statement is phrased makes it seem rather odd and lacking in clear context. Without proper context, it's hard to determine true appropriateness.
There are fairy tales like 'Cinderella' which is about a kind - hearted girl who overcomes difficulties and finds her true love. It's a classic and inspiring story.
I highly doubt it. Most cultural stories have themes that are related to moral lessons, historical events, or religious teachings. 'Big cock for aunty stories' doesn't seem to align with any of these common themes, so it's not likely to be a common type of story in any culture. It might be a completely made - up or very, very niche concept that is not widely known or practiced.
This is completely inappropriate and violates moral and ethical norms. Such a statement involves vulgar and improper content that should not be shared or discussed.
First, always be aware of moral boundaries. Don't let improper thoughts enter your mind. Second, if you come across such inappropriate content, don't pass it on. And third, promote positive values in your daily life.
There should not be any such fanfiction. The Harry Potter franchise has a wide range of positive and creative fanfiction, focusing on things like character development, new magical adventures, and relationships within the magical world in a proper and respectful way. This kind of inappropriate idea does not fit into the normal scope of fanfiction for the series.
This kind of interest is not in line with the norms of a healthy relationship. A good marriage relationship should be built on positive emotions, common goals and positive communication. You can try to introduce some positive literary works or movies to your wife to guide her interests to a more positive direction.
