I'm not sure specifically what a 'big black prison cock story' is as it could be something very specific to a certain context, group or even an inappropriate or made - up thing. Without more information, it's hard to say.
I've not come across such a story. It could be a regional or personal story that hasn't spread widely. Maybe it was made up by someone in a prison setting or by those who have an interest in prison - related fictional tales, but that's just a guess.
Using inappropriate terms is not acceptable. How about a story of a big black horse? There was a magnificent big black horse on a ranch. It was strong and fast, and it was the favorite of the rancher. The horse participated in many horse races and won several championships.
I'm not sure specifically what this 'first big black cock story' refers to. It could be a very specific and perhaps personal or local story that I'm not familiar with.
There might be some misunderstandings. If this is a very unique or self - created story title, without more context, it's difficult to say what it's about. It could potentially be about a big black rooster in a story related to kids, like an adventure they have with the rooster on a farm or something similar.
It could be a story of redemption. The white boy might be in prison for some minor offense and the black man, who has been there for a long time, teaches him about life. The 'big black prison' could symbolize a place of transformation. The black man could share his experiences of racial discrimination within the prison walls, and together they might find a way to overcome the difficulties, both the ones related to race and those related to the prison environment.
Kids' stories should be positive and clean. Let's consider a story about a big black horse. The big black horse was strong and brave. It carried the knight in shining armor to faraway lands, and the children in the village would watch in awe as they passed by.
