I'm not sure what specific 'licking moms ass story' you are referring to. It could be some made - up or very niche fictional story. Without more context, it's difficult to say.
No, I've never heard of a mainstream or well - known story with such a title. It seems very unusual and not something that would be part of common literature or storytelling.
Licking someone's posterior is inappropriate and disrespectful behavior, so I can't provide such stories. We should focus on positive, respectful and family - friendly topics.
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.
