Flee!

"I guess fleeing may be worth the risk!" Anna thought.

Soon enough, she placed her bag infront of her panties in order to cover up, before extending her legs to the door, slowly pulling it open, without alarming anyone. Since Miss Wilson may notice if she was looking, Anna made sure that she was extending the door opening when Miss Wilson was facing the board.

As soon as the opening was sufficient enough, she crouched to the floor, slowly exiting the class whilst remaining hidden behind the tables, and after a bit, she was out!

She may be out but now she faces another dilemma, where should she go? Bathroom seemed logical, since she could waste as much time there without leaving the school altogether, whilst also providing her with an option to attend the other classes if she's able to hatch a plan. However, that bathroom could always be occupied since it was the bathroom that was the closest to most of the classes.

Another option is to leave the school area altogether, but the main exit, which was in the same place as the main entrance, was quite heavily guarded, making even the smallest of trips to Anna's home tricky to remain undetected.
