Her nemesis

When Anna turned to see who was snickering she was greeted to the face of Jenny, her nemesis.

Jenny and Anna have been enemies since they first met. She showed jealousy towards Anna as she was smarter than her and outshined her at every moment.

Before Anna came around she was top of the class with no competition. When Anna arrived she showed her true feelings of hatred to her almost immediately in which Anna returned by making a fool out of her at several occasions.

....

"How brave and daring Anna!" said Jenny with a chuckle.

"It's not what it looks like at all! I swear!" flushed Anna.

"Oh by the way, nice pussy Anna." said a still laughing Jenny.

Anna, acting on impulse, raised her legs to cover her private spot while her panties fell to the ground.

Jenny, who was just beside her grabbed her panties when she noticed them on the ground.

"Looks like you won't be needing this anymore!" said Jenny while waving her panties.

"Give them back!" said Anna not wanting to cause a scene and catch the teacher's attention.
