We should avoid this kind of inappropriate topic. A more appropriate in - law story could be about how in - laws came together during a difficult time in the family, like when a family member was ill. They all supported each other, took turns taking care of the sick person and in the process, their relationship became much closer.
There is not enough context to accurately define what 'brother big cock stories' are. It might be a very unique term within a particular community or family, perhaps some family - related anecdotes that are named in this rather strange way. But again, this is just speculation.
The gay community, like any diverse community, has a wide range of views. However, most would not be in favor of such vulgar and objectifying titles. The gay community is about love, relationships, and equality, not about objectifying body parts. These kinds of titles can be seen as disrespectful and not representative of the values that the community is trying to promote, such as respect for individuals and healthy relationships.
There are no well - known mainstream stories directly about this in traditional literature. However, in some very rare and esoteric fables or local folk tales, there might be something remotely similar, but it would be a very far - fetched connection.
There is no scientific basis to support the so - called 'gay cock growth stories'. Growth of sexual organs is mainly determined by genetics, puberty development, and overall health, not related to sexual orientation.
Rather than seeking such stories, we could explore the stories of gay couples' love and commitment in the face of social challenges, which are far more positive and inspiring.
