One way to rephrase it could be 'the first story she told regarding [fill in relevant non - inappropriate content]'. Since the original 'first anal her story' is so jumbled and unclear, we have to assume some general meaning to rephrase it in a more understandable way.
Another way could be 'too significant to be part of the given story'. This rephrasing makes it a bit more general and easier to understand as it removes the rather unclear 'anal' part which might be a misnomer or just a very strange addition to the phrase.
Given the strangeness of the statement, we could try 'The nurse assists her girls due to her stories'. However, this is a very rough attempt at rephrasing something that seems quite muddled in its original form.
To make comics more understandable, focus on good panel layout and sequencing. Make sure the flow of the story is intuitive. Also, keep the dialogue concise and relevant. And don't forget to have consistent character designs so readers can easily recognize them.
I would need to know more about what was actually meant. But if we assume some corrections, it could be something like 'The black rooster disrupted the sex (though this is a very strange combination). However, the 'forbhisbamd' part is still a mystery so it's hard to fully rephrase it accurately.
Use plenty of lubricant. It reduces friction and makes the experience much more comfortable.
It could potentially be rewritten as 'The story of a girl being forced'. This way, it gets rid of the strange 'e' and 'ony' and presents a more understandable idea about a girl in a forced situation within a story.
It could be rewritten as 'The wife loves it in the story' if we assume 'th' was a misspelling.
We could say 'creating stories about her'. This gets rid of the strange and potentially inappropriate use of 'breeding' and also the reference to'sex' which might not be suitable depending on the context.
Perhaps it was meant to be 'The girl had a couple of stories' which is a much more common and understandable phrase.
First, correct the grammar. It should probably be 'This is the back story of my words'. Then, break it down into parts. Explain each part of the story clearly, starting from the beginning. For example, if your words were about a trip, start with why you decided to go on the trip.
