She was a good student, but Miki Igami's true heart was perverted. She was a masturbation addict.

"Even though it's wrong... I shouldn't do it here... but it feels so good!"

Miki removed her clothes and exposed her creamy skin as her fingers teased her clitoris.
It was thrilling to be watched by shocked and horny strangers.
She couldn't put the brakes on her behavior. It was getting worse and worse.

"I'm sick... I'm a sick girl... I'm such a bad girl... I don't care! I like being bad...!"
