I'm not sure specifically what this 'xnxx mom seduc story' is as it's not a common or known mainstream story. It could be something very specific within a certain context or perhaps even something made - up.
Definitely not. There are no popular or mainstream stories with such a name. It might be something very specific to a small group or an individual's creation that hasn't gained wider recognition.
One of the main differences is that Hideo Azuma's manga might focus more on psychological depth and character introspection. Also, the visual aesthetics could be more avant-garde compared to typical manga.
