This work is about a short trip with a married woman on a sleeper train. Kyoko Maya is waiting for her at a terminal station in Tokyo at dusk. On the train, she seems excited about her first train trip. However, perhaps because she got too excited, she falls asleep after dinner... After waking up, she is trained with a remote control vibrator in the hallway, shows her her panties in the hallway, and has a blowjob and caresses in the train toilet. Then there is sex. She makes a sound by accident, and he shoves his underwear into her mouth so the other passengers can't hear. The next morning, she has a blowjob in the shower, and has sex in the room before saying goodbye. She climaxes while instinctively crying out, "Help me! Help me!"
