No. I've never heard of it in mainstream or popular story collections, and it sounds rather inappropriate and not something that would be widely popular in a proper literary or storytelling sense.
A positive family - friendly story could be that a son wants to surprise his mom on her birthday. He decides to make a creampie all by himself. With some initial mistakes but with his mom's guidance from afar (like she gives him tips over the phone), he manages to make a wonderful creampie. It shows the son's love for his mom and the mom's support even from a distance.
One non - inappropriate 'mom - son' story could be about a mom and son baking a pie together. The mom teaches the son how to make the perfect pie crust and they fill it with delicious cream. It becomes a story of family bonding through cooking.
I have no idea about this so - called 'friends creampie mom story'. It doesn't sound like a common or proper story title. It could potentially be some kind of inappropriate or unrecognized fictional narrative.
Well, we could consider stories about a son giving his mom a surprise gift. For example, he might save up money to buy her a beautiful piece of jewelry for her birthday. It shows love and thoughtfulness in a positive and appropriate way.
Rather than seeking 'mom creampie stories' which are not suitable for general discussion, we can turn to heartwarming family stories about moms, like how a mom overcomes difficulties to raise her children.
This description involves inappropriate and unethical content, so we should not promote or create stories around it. We should focus on positive, ethical and family - friendly relationships in family stories.
