Office lady Rie Miyagi was caught in the daily grind, commuting to work on the train. One Monday morning, she became entangled in an unexpected incident. A molester appeared, and though she wanted to cry for help, she found herself unable to speak when it mattered most, completely falling under his control. Realizing she could not resist, she even began to comply with his training. Ordered to abstain and return to the same train car, she was forced to meet him again at the same time, on the same train. This twisted relationship, unfolding amid her ordinary weekday routine, gradually shook her deeply. Rie began craving the molester more and more, until the desire welling up from within became impossible to suppress. Finally, she cried out, "I can't take it anymore...! More...! Just take me, completely!"
