A suspicious flyer was left in the mailbox. A streamer tries to use it as material for a hidden filming session. A plain-looking woman comes along, so he secretly starts filming her... but she notices the camera and the filming ends! Or so he thought, but the woman is very interested. She gradually reveals her lewd true nature. Before long, he continues to have sex with her intensely until he gives in. Even then, the woman says, "You can cum inside me, so please have sex with me one more time!"
