We turned our attention back to the overachiever character type after some time. She has the poised, dignified look of a student council president, giving off a strictly proper impression at first glance. When reviewing the footage at home, we confirmed she was indeed wearing modest, traditional panties just as expected, which came as a slight surprise. This type of character usually has a strong sense of justice, and though clearly nervous inside, I carefully began touching her. At the first station, I proceeded slowly to avoid detection; from the second station onward, I gradually grew bolder. As I started touching the crotch area, I could feel her legs twitch in response. Keeping quiet, I slipped my fingers inside her panties and continued stimulating her. She desperately tried to resist, but eventually, whether she gave up or simply gave in to pleasure, her resistance faded away. I made sure to thoroughly deliver pleasure until she got off the train.
