You could say something like 'I made up stories about my brothers' growth' which is more appropriate and easier to understand.
You have such a lovely item for me.
If you are talking about some fictional or humorous stories related to growth in a non - inappropriate way, you need to be more specific. For example, are they about the growth of something positive like a plant named 'brothers cock' in a storybook? Without more details, it's hard to give a proper response.
A better statement could be 'Girls first when it comes to sharing their experiences'. This emphasizes the importance of listening to girls' experiences in a broad and appropriate way, rather than having any connection to sexual stories.
We could rewrite it as 'The story of a sister's interaction with her brother in an extreme way'. This gets rid of the vulgar part and still gives the idea that there is some sort of intense or unusual relationship between them in the story.
Once, I saw a big rooster in the countryside. It was so bold that it chased a dog. It flapped its big wings and crowed loudly as if it was the king of the farmyard.
This statement is inappropriate and unclear. It might be a very vulgar and ungrammatical expression. We should avoid using such expressions in proper communication.
Sorry, I don't have a particular 'brothers big cock story' to share at the moment.
If we assume 'cock' is referring to a rooster, it could be 'Mom measures my young rooster.'
She dates him perhaps due to some aspect of their sexual relationship or attraction. But this is a very general and more acceptable way compared to the original statement.
One way to rewrite it could be 'A Story for My Beloved Wife'. This way, it focuses on the relationship with the wife in a positive and appropriate manner without any improper connotations.
