Perhaps 'A mother's improper actions are part of a concerning story'. This tries to convey a similar idea but without the vulgarity.
One could say 'A mother's actions that are not proper make up a story of inappropriate behavior'. This is a way to rephrase it while still keeping the general idea but making it more acceptable.
This statement contains inappropriate and disrespectful content, so I can't provide a positive interpretation for it.
The story about mom seeing me arrive.
If we assume 'cock' is referring to a rooster, it could be 'Mom measures my young rooster.'
The mom and daughter could be teasing about a new art project they are working on that involves some prickly materials like wire or bristle brushes. In the end, they complete the project and it turns out to be a beautiful piece that they donate to a local community center. The community is happy, and they feel good about their contribution, which makes for a positive ending.
Perhaps they are in a baking competition within the family. They keep showing off their baking skills in a teasing way, like saying how their cake is going to be so much better because of this special 'prickly' ingredient (like a unique type of spice). They give little hints but don't fully reveal what they are doing until the big reveal at the end.
You have such a lovely item for me.
A more appropriate way might be 'I found myself in a situation regarding same - sex relations that was uncovered (while maintaining respect).'
One way could be 'Beta submits a story about a gay relationship.' This gets rid of the inappropriate terms and makes it more understandable.
We could rewrite it as 'Two Women's Intriguing Encounter'.
We could rewrite it as 'forced to endure their difficult demands story'. This changes the vulgar - sounding part into a more general and acceptable term about dealing with difficult requirements.
