The first half of this movie is believable as we have a very pretty and unique looking Japanese babe take an "interest" in a young stud who is riding the train. The second half though is less believable as they move into a private toilet and proceed to have a suck and fuck fest. The camera films away during their "private" tryst negating any realism from the film. A possibility that he is talked into letting the camera film him in exchange for that tempting piece of sushi before him. Good sex and hot lady, but something about toilet sex that just doesn't do it for me.
