The urge to cum grew and grew. She wondered if she could make it to bathroom before the urge grew too strong. Her thoughts were interrupted as she heard a loud scream. Jenny looked over to see one of her classmates screaming in orgasm while fingering herself. Jenny realized that in this world, it must be acceptable for girls to get themselves to orgasm in public.
Jenny started to remove her skirt and moved a finger inside her panties. She felt nervous and embarrassed that she was about to masturbate in the middle of class. After what seemed like an eternity, she began to pleasure herself. It felt so good. That's when she remembered the vibrator her mother had given her. She reached for it and stuck it inside her wet pussy. She turned it on and began to moan in pleasure. There were more moans joining her's as other girls in the class started to pleasure themselves to form some sort of sick masturbation symphony.
Because the vibrator took care of her pussy, her hands were now free to fondle her breasts. After a few minutes, she achieved orgasm. By that time class was over.
