She has magnificently large breasts that can be seen even through her clothes. When she gets on the train, the crowds and the swaying cause her voluptuous breasts to bump into the man, making him horny. Her shy gesture of holding her breasts further increases the man's excitement, and he can no longer contain himself and molests her. Her breasts, which don't fit in the palm of his hand, are fondled, her nipples are teased, and she has sex standing up. He then splashes his semen all over her big breasts!
