High school girls, driven to unbearable climax by a pervert on a crowded train (T28-347)

Unlike typical perverted behavior... a penis was inserted inside the train!? The target was a timid, adult-like high school girl, who, even when she mustered the courage to cry for help, received no response. In her shock, the intense thrusting and penetration overwhelmed the girls, who couldn't take it anymore, and their lewd sounds echoed throughout the train!
