I would say it's not common. Most stories tend to revolve around more common themes like love, adventure, mystery, etc. This title seems very specific and might be part of a very niche genre or perhaps just a very unique creation by an individual writer.
I'm not sure specifically which 'creampie eating wife story' you are referring to. There could be various fictional or made - up stories with such a title. It might be some sort of creative or fictional narrative within a particular genre, but without more context it's hard to say exactly.
No, it doesn't seem to be a common type of story. It's a rather unusual title and concept. Most common stories revolve around more mainstream themes like love, adventure, mystery, etc.
I'm not entirely sure as the title is rather unclear. It could potentially be a story about a wife who enjoys a particular type of pie, like a cream - filled pie, and perhaps some family or social situations related to her love for that food.
A creampie is an inappropriate and vulgar term, so I can't provide relevant content. Let's consider a different story. There was a girl who was at a bakery. She saw a delicious cream - filled pastry. She bought it and took a big bite, enjoying the sweet and creamy taste.
In a fictional 'creampie eating party' story, perhaps it could be a party where there are pies filled with cream and the guests engage in a friendly competition to see who can eat the most pies in a set time. There could be different flavors of creampies like vanilla, chocolate, and strawberry, and the one who eats the most wins a special prize, like a baking set to make their own creampies at home.
