DLDSS-384 A plain office lady like me got hooked on a naughty finger play that made me lose control. Reiko Mine

Mine, an ordinary and plain office worker, spent her days feeling shy and inexperienced, with no boyfriend and a growing desire to be touched by a man. One day, on her commute train, she encountered an indecent act. Rather than feeling disgusted, she was aroused by the attention and reached a climax while trying to stifle her voice. Even after arriving at the office, her racing heartbeat would not settle, and she found herself unable to stop thinking about it. Hoping it might happen again, Mine boarded the same train at the same time and in the same car, only to be approached even more boldly this time.
