A member of a film research club in the Faculty of Economics, 'Arisu' comes from a sheltered background as the daughter of a local government worker. A literature student known for her innocence, she agreed to participate in a reading session wearing "jumping panties" for the first time. With only three partners in her past, the sensation of the vibrator directly stimulating her shaved pussy was so intense that she involuntarily urinated. Despite one challenge after another, the young lady continued reading without stopping—even as her panties were removed, she was straddled, and before she realized it, penetration had already occurred. Can she really see the reading through to the end?
