Another way is to think of 'cock' as a misspelling or a creative name for something else. For example, it could be a character's nickname, and 'feeling cock' would then mean having an impression or intuition about this character. Maybe it's a character that gives off a certain vibe, like being confident or proud, and 'cock' is used as a unique identifier in the story.
Perhaps 'cock' is used as an abbreviation or a term within the story's own jargon. It could stand for something like 'Cockpit' if it's a story about aviation or flying machines. So 'feeling cock' would be about having a sense of the cockpit area, like the character feeling the controls or the confined space of the cockpit.
If we consider 'cock' as a bird, 'feeling cock in stories' could be about the awareness of a rooster within the narrative. It might be related to the role the rooster plays, such as being a symbol of the start of a new day, or it could be part of the scenery where the characters interact with the rooster on a farm or in a rural setting.
