One way could be 'True story about a dog and a brother's strange situation'. This gets rid of the unclear and potentially inappropriate 'sex' part and focuses on the general idea of a strange story involving a dog and a brother.
The phrase is rather unclear and hard to make sense of as it is. It might be a very strange or misphrased description. It could potentially refer to some sort of odd or true story involving a dog and a brother, but without more context, it's very difficult to determine exactly what it means.
One way could be 'Beta submits a story about a gay relationship.' This gets rid of the inappropriate terms and makes it more understandable.
My brother's wife has a great story for me.
We could rewrite it as 'The story of a brother and sister's unexpected situation with a baby'.
I would rewrite it as 'A story described in Telugu regarding my friend's mother'. This makes it more straightforward and appropriate.
It could be rewritten as 'The wife loves it in the story' if we assume 'th' was a misspelling.
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.
Maybe 'A story related to a wife and an initial large... (thing)' where we remove the inappropriate connotation of the original phrase.
Perhaps it was meant to be 'The girl had a couple of stories' which is a much more common and understandable phrase.
We could rewrite it as 'The person/thing named Jerker visits once more'.
