This series focuses on high school girls with "hidden big breasts" that are bigger than they look. When they get close to each other, their large breasts are clearly visible against the man, and the more she tries to move away in embarrassment, the more her breasts end up rubbing against the man's body... The man, aroused, can no longer contain himself and begins molesting her. He forces her to expose the big breasts hidden under her uniform and continues to molest her, and although she is reluctant, she becomes excited...
