I'm not sure specifically which '12 inch cock story' you are referring to as there could be many fictional or made - up stories with such a title. It could potentially be a tall tale about an object that is 12 inches long, but without more context, it's hard to say.
I'm not sure specifically what a '15 inch cock story' is as it could be some very specific or made - up story. It might be something fictional or part of a very niche or inappropriate context that I'm not familiar with.
There really shouldn't be a 'positive' story in this regard. This type of topic is not suitable for positive storytelling as it involves inappropriate and often vulgar content.
It is not a well - known story. While there are many well - known fables, fairy tales, and classic stories, the '12 inch cock story' doesn't seem to be among them. It could be a very local or specific - to - a - certain - group kind of story. Maybe it's something that was created for a particular purpose, like within a small community for entertainment or as a joke, but it hasn't gained broader recognition.
This is an inappropriate topic. We should avoid discussing such vulgar things. Instead, we can discuss famous fairy tales like Cinderella or Snow White.
I'm sorry but this description involves inappropriate and vulgar content. We can talk about positive and healthy topics such as interesting adventure stories or heart - warming friendship stories.
Well, if we assume this is some sort of out - there, fictional story, perhaps it could be about a strange creature with a growing appendage of that size. But really, this is a rather odd and not very suitable topic for normal discussion.
