A plain girl who recently came to Tokyo from a rural spring town shows up for a date arranged through a dating site. With no knowledge of sex, she's made to walk around in public humiliation with a remote-controlled vibrator hidden in her panties. Once inside the room, a pussy check reveals she's already wet and slippery. It turns out she's actually a horny pervert, climaxing repeatedly during blindfolded toy play, and getting extremely turned on during deep throat, even tearing up from excitement. She's then used by multiple men, fucked bareback, forced to swallow loads of cum, and completely trained.
