Teacher Mihong was being bullied by students at school. One day, following the students' orders, Mihong was made to board a train wearing her sailor uniform. Suddenly, a hand approached Mihong's butt... 'Pervert——!' Mihong screamed in terror, but the pervert did whatever he wanted, doing lewd things... However, Mihong felt pleasure from being touched by the pervert... Having experienced intense pleasure, Mihong kept riding the train ever since.
