Sakurai:02 - My Girlfriend's Little Sister is a Hot Devil

After fooling with the lawyer from the previous chapter, Sakurai finds her new prey while on the train. And he just so happens to be her sisters boyfriend! She reels him in with panty shots, then lures him to a love hotel to test and see just how much of a pervert her sisters boyfriend is. Frustrated with how uptight (and flat) his girlfriend is, he ends up falling hook, line and sinker.
