There are many other great stories to tell, such as heartwarming family moments, acts of kindness, or inspiring personal achievements that are much more worthy of sharing.
Stories about a mother's selfless love for her children are great replacements. For example, a mother who works multiple jobs to provide for her kids' education and still finds time to be there for them at every important moment in their lives.
I'm not sure specifically what a 'pussy cock story' would be as it's not a common or well - defined term. It could potentially be some sort of made - up or very specific local slang.
This is extremely inappropriate behavior. Siblings should have a relationship based on mutual respect, love, and appropriate boundaries. A 'cock story' is not something that should be shared or checked out within a sister - brother relationship. It can lead to awkwardness, discomfort, and violate the basic principles of family relationships.
