A man gets into a train car full of women. Not realizing that the man had pretended to be mistaken, his crotch brushes against his buttocks, and the woman, turned on by an unexpected kiss caused by the shaking of the train, reaches out to the man's body and gently teases him without being noticed by the people around. As she gives him a handjob and rubs her crotch against his erect penis, the woman becomes so excited that she even demands sex.
