Can you rewrite 'big cock for wife story' into a more appropriate title?

A more appropriate title could be 'A Peculiar Wardrobe Mishap Story' if we are trying to keep some of the humor without the vulgarity.

You have such a lovely item for me.

We could rewrite it as 'Two Women's Intriguing Encounter'.

Sure. We could change it to 'A story of accidental contact'. It gets rid of the inappropriate words and still gives an idea of something unexpected happening in a more acceptable way.

We could rewrite it as 'Big event disrupts wife's story'. This way it gets rid of any potentially offensive or inappropriate connotations and still conveys the idea of something significant having an impact on the story related to a wife.

Another option is 'In a CBT story, no excessive dominance is allowed'. This rewrite keeps the focus on the CBT aspect and clearly states that there should be no extreme form of dominance in the story, which was what the original phrase was trying to imply in a rather unclear and inappropriate way.

The girl's encounter with a significant object. This way we can remove the inappropriate part and still imply that the girl has an encounter with something that might be important or large in a symbolic sense.

Maybe 'The Tale of a Wife's Unfaithfulness'. This title conveys the same basic concept as the original but without the use of offensive and disrespectful words.

Sure. It could be 'Boys' First Encounter Story' or 'Boys' First Experience Story'.

We could rewrite it as a story about a wife finding a more positive and fulfilling connection with someone who has a bigger heart. So instead of focusing on a vulgar aspect, it becomes about emotional depth.
