Masato goes to school in a crowded train every day. It is really hard, but he enjoys it because of Saya, who is always in the same train. He is in love with her though she is cold to him. One day, when he is in a crowded train as usual, he accidentally touches her breasts and bottom. Thanks to crowded train (?), he can't move at all and his erected dick keeps pushing her. Saya tries to resist it at first, but she gradually feels sexually aroused, "Oh, Masato.... Oh...." When they get off the train, he immediately says, "I'm really sorry!" "Oh, you don't need to apologize. I felt really comfortable...." Like this, their strange relationship starts....
