On the commuter train, Reiji was unable to resist the vile man who was groping her all over. She was so shocked and scared that she couldn't move or even make a sound. She just let him do whatever he wanted and ended up climaxing right there on the train, squirting juices... A few days later, Reiji returned to her daily life in an attempt to shake off the nightmare, but the experience kept flashing back to her. It was supposed to have been a humiliating experience, but all that came back to her mind was the pleasure that had been engraved into her body. She wanted to ride that train again. Reiji couldn't suppress the lustful desires that were welling up inside her.
