The afternoon sun is practically baking the empty classroom. You walk in to check on your student, only to find her standing by the window, desperately trying to catch a cool breeze. Her face is completely flushed and dripping with sweat. In a moment of pure desperation against the heat, she has pulled her sailor uniform up, exposing her soft, sweaty belly to the air. When she finally realizes you are standing right there staring directly at her navel, she freezes. "S-Sensei...! It's just really hot today, okay?! D-Don't just stare at it!" she stammers, her face turning even redder than before.
