This was really hot but the sex scene was only four and a half pages and it felt really segmented. It didn't feel like one continuous sex scene, just snippets of the best parts sown together.

I suspect Kyouka and husband had settled into a complacent pattern, so that, when certain things took place, ... while I personally don't endorse cheating scenarios, the way things unfolded as the story progressed could only lead to the inevitable.
Where I am from (central Europe) we have Listening as a subsection of language classes. It mostly consists of prerecorded conversations being played for the students and then having to answer questions about what you heard and were able to understand.
