Newly appointed teacher Machiko Natsukawa finds herself in big trouble when one of her students gets blackmail material on her in the form of a signed pair of panties. Now she’s forced to participate in sex orgies with the male and female delinquints in school. Not only that, but her class is packed full of sadists, nymphomaniacs, a sexually deranged nerd, a girl with a very big secret hidden under her skirt, and a mysterious network of spy cameras that puts her exploits in the public eye. Machiko isn’t likely to get control of her class any time soon!
