Really? I never see what Asuka is doing as teasing. She always strikes me as frighteningly sincere.
Her "motherly" behavior is nurturing, but it's also something we now know for sure she does for no one else.
With Uchi and Asuka, I think what we're seeing is a writer doing a subtle and sensitive job depicting what actually happens when "yuri" surfaces.
Now what Tomoko thinks, there's no way of telling. What is sure is that she tends to be way more interested in real-life women than real-life men.
