If 'cock' is used in a non - traditional sense like for a large object, then it could be 'Her first large object (referred to as cock) story' which is still a bit unclear but tries to make sense of the original title without the number symbol.
Her first large cock story.
If we assume 'cock' here means rooster, it could be a title like 'Her first large rooster story' which might be about her experience with a large rooster, perhaps raising it, or an adventure involving the large rooster.
It could potentially be about a woman's first experience with something large, perhaps a large animal like a large rooster (cock can mean rooster in some contexts) and the story related to that first encounter.
A more appropriate title could be 'A Peculiar Wardrobe Mishap Story' if we are trying to keep some of the humor without the vulgarity.
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.
Sure. It could be 'Boys' First Encounter Story' or 'Boys' First Experience Story'.
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.
The Story of Wife's First Experience with a 'Monster Cock'.
You could also say 'Something was pulsating in her hand'. This vaguer term gets rid of the inappropriate word and still conveys the basic idea of something having a pulsating motion while in her hand.
I'm sorry, but this phrase contains inappropriate content that cannot be simply 'rewritten' into an appropriate form while keeping those words. It's better to use a completely different and positive description like 'The husband was forced to watch a big - scale story' (though this is just a made - up example to show the idea of changing to appropriate content).
You could rewrite it as 'My Wife's First Unusual Social Experience'. This way it gives a sense of something different that happened without the inappropriate connotations.
How about 'My First Special Stories'? This way it removes the inappropriate connotation.
