When the senior Chemistry class arrived for their lecture on Tuesday morning, they were greeted with an unusual sight. Standing on top of one of the long black lab desks was senior cheerleader Susan Mitchell. She was naked, as usual, with her legs spread wide and tied with rope to the table top. Her hands were bound behind her back. Placed between her legs was a Bunsen burner stand and the flame from the burner itself flickered just a few inches from the girl's bare pussy. The students could sense Susan's discomfort as she wriggled in her bonds, the heat from the flame close enough to warm her, but not too close where it would burn her skin. The students had no idea how long the girl had been posed in this position.
