Since this is such a strange and potentially inappropriate concept, it's difficult to give a proper story. However, if we were in a world of very strange and absurd fantasies, it might be part of a story about a mutant animal where the growth of this part of its body is a central and very odd plot point, but again, this is all very much in the realm of the inappropriate and strange.
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.
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 could be a fable. In a land where all the animals have special abilities based on their size. A small and meek cock is given a special gift by a fairy that makes it grow huge. At first, the other animals are scared and avoid it. But as time passes, the cock uses its new size to protect the other animals from a common enemy, teaching a lesson about how even the most unexpected changes can bring about positive outcomes.
I'm not entirely sure what a specific 'growing cock story' refers to. It could potentially be a story about the growth of a rooster perhaps? Without more context, it's difficult to say for sure.
