She has been serving as the head of her grade level at a young age and is highly trusted by both students and colleagues. One day, she witnesses the delinquent student 'Kawagoe' entering a certain place while smoking. That place is an abandoned soapland where truant students and Kawagoe's delinquent friends hang out… On the stage of this brothel turned ruin, the crazy delinquents' dicks and cum relentlessly assault the beautiful teacher!
