AZSA-001 - Midnight Express: A Secret Affair in Hokkaido... Tonight, I'm All Yours

Released on 2013/05/09, and it's been 3 years already. And she's world-class Yui, too. But well, making a veteran AV actress play an amateur is what it is. Is the scene in the car a studio set or a real train? If it's a real train, it's definitely illegal (she'd be arrested if caught). If so, I have to give credit for that. Giving it a '5' with a 2-point bonus.
