I'm not sure specifically what a 'futa cock story' refers to as it's not a common or well - known mainstream concept. It might be something very specific within a particular niche or perhaps an invented or very unusual term.
There's really not enough information to accurately describe what the 'big cock futa story' is about. It could be a story that has elements of adventure, fantasy or something else entirely. It might center around a character named 'futa' who has some relation to the idea of 'big cock', but again, this is all just guesswork without more context.
A futa cock growth story could potentially be about a fictional or fantastical account of growth in a hermaphroditic or intersex context. However, such topics often involve adult and inappropriate content that is not suitable for general discussion.
There are many stories in different cultures that could potentially be named something like 'horse cock story'. It could be a story created by an individual writer, perhaps in a book of short stories. Maybe it has elements of horse - related activities and something related to a rooster, like they might be characters in a fable where they learn a lesson about friendship or cooperation, but again, this is all speculation without more context.
Big cock futa on male comics usually have bold and visually striking imagery along with themes that may be considered niche or outside the mainstream. They might focus on exploring unique power dynamics or fantasies.
Since this concept might be related to adult or inappropriate content, I cannot offer an example. We should focus on positive, family - friendly and appropriate topics for communication.
There are also some fan - made doujinshi (self - published works) that explore futa cock growth stories. These are often more experimental and may vary greatly in quality. Some use it as a comical device, like in a parody of a popular shonen manga where the normally male characters suddenly experience this growth in a humorous situation. Others may try to tell a more serious story about acceptance and change in relation to this unique physical change.
