Due to her parents' circumstances, she suddenly had to transfer schools, and her new uniform wouldn't arrive in time, so she had to keep wearing her old school uniform for a while. It was her first time living in the city, and the commute from home to school was quite long. She had to take the 7:23 train, reassuring herself that she wouldn't get lost or miss her transfer. But as she rode, she suddenly noticed, "Huh? Something's touching my butt?" No—she was being groped... This was it—molestation! So molesters really do exist in the city... What should she do? She was too scared to turn around, too frightened to speak. The groping only intensified. A finger slipped into her panties—this was bad, it felt good... She was about to make a strange noise. I have to endure it... I have to endure! He started groping her breasts too. Isn't this too bold? Isn't anyone noticing? I can't let anyone know I'm getting turned on... The molestation continued all the way to her stop. And the molester got off at the same station. More than fear, she was overwhelmed by pleasure. It had become a special, thrilling, exhilarating moment shared only between her and that man. During class, she found herself touching her pussy while remembering the groping. From the next day on, she began riding the train hoping to be molested again. At the same time, same car—it was him again... The same ring. There were fewer people today. Taking advantage of everyone sleeping, the molestation escalated even further. Wait! Are you seriously going to insert it here? That's too much... This is dangerous... But it's... too amazing. Having sex secretly with a stranger, unable to make a sound, with people all around, and getting creampie right there. Am I a total pervert for getting so excited? Her new uniform finally arrived. Once she started wearing it, the molestation suddenly stopped... Maybe he didn't like the new uniform? She found out the reason a little later. On the day her homeroom teacher was absent, she saw the substitute teacher for the first time. Ah—that ring... It was the substitute teacher who had molested her. He had no idea she was his own student. But when he saw her in the new uniform, he got scared and stopped. She called him out and begged him to keep quiet—instead, she asked him to have sex with her in the classroom. Sex on the train wasn't enough anymore. She craved even more excitement. The next day, she hoped once again that the substitute would molest her. He's here! He's here! That feeling of him pressing tightly against her back. Huh? But the way he's touching feels different... She glanced back slightly—w-who is this!? She was being molested by a completely unknown man. The teacher had run away, scared. He must have leaked her information to a molester circle. But at this point, it didn't matter who it was. As long as someone made her excited, anyone would do... Since then, every day at 7:23, in the third car from the front, she's been enjoying one molestation session after another with different men.
