Miyu, a high school girl who commutes by train, is a victim of molestation every day. "This guy is a molester!" How nice it would be if she was the type of person who could say that out loud. Timid and quiet, she could only endure the creepy sensation of someone caressing her buttocks in a lewd manner under her skirt. Biting her lip tightly, she stares at the electronic display board to her destination station. However... the molester that day was different. His touch was different. Her love juices unconsciously started to overflow. It felt... good. She even wished he would touch her more. Even though we were on a train, and there were many people around, I... had a strange man touch my private parts... and I was going to cum!
