When they get on the bus, the windows turn into magic mirrors, asking, "Would you like to try being an underwear monitor?" Driven by the desire for a date fee, a girl agrees and waits for her boyfriend outside the bus, completing a naughty mission! Despite her boyfriend being right next to the window, her heart races as she ends up having sex with another guy.
