A Full Flash

The Teacher - Tanya - shifts her position a little and you use that as your opportunity. A simple movement with your finger and the jogging bottoms slide down her legs, all the way past her knees to rest around her ankles, all of the pupils suddenly wide eyed at the sight of their teachers furry bush.

You keep her unaware for a moment, and she calls out "into Warrior" and steps to the side.

It takes quick thinking on your part to finish the rip along the gusset of her jogging bottoms, allowing them to separate completely as she spreads her legs and stretches out her arms into the lunge.

You, and all five of the students are treated to the view of their teacher naked from the waist down, her legs spread in a lunge.
