To those of you might not get what's going on the third panel: Senka's classmate is inhaling in preparation to calling attention to them.

She says as much. Translation revised.

Why in the Hell did they omit the 2nd-to-the-last-panel!?!?!?!
I got excited for nothing!!!

Why is she undressed?

Because it's sexier that way.

for the lazy and non kashiwamochi yomogi nuts (philistines!) post #666918 is likely the omitted panel.
