Girls and couples on the street stop by the Adbus's quick decision/quick payment ads running through the city. When they get on the bus, the windows are magic mirrors, and the girl says, "Would you like to try underwear monitoring?" The girl agrees, wanting money for a date, and leaves her boyfriend waiting outside the car to complete the naughty mission! Even though he's next to the window, she's so excited that she ends up having sex with another guy's dick.
