Does anyone know the JAV code for this?

I've had this video for quite awhile, but I've been able to track down the origin or JAV code. The full video depicts a young woman in a skirt and thigh high socks boarding a train. From there, she's seduced/fingered, before exiting the train while being followed into the train station bathroom stall where she and her seducer fuck doggystyle. Even based on that search criteria, I've been unable to locate the code. Can anyone help? Thanks.
