Fluent in English... The lewd female teacher Ururu Jun, who straddles the world with sex, has come to a low-ranking school with a ranking of 35! Passionately guiding the students towards the event "SEX CULTURE WORLD EXPO" at the cultural festival held in autumn! Breasts, ass, mouth, lewd words, hip movements... I can't stop cumming at Ururu-sensei's body language! And then came the day of the cultural festival... A moving finale where the scattered class becomes one! Eroticism saves the world!!
