When the married masseuse arrives at the room, the client jokingly says, "One million yen♪" as a tease. Though she chats casually with this regular customer, they've actually been having a secret physical relationship for some time. While pretending to give a massage as usual, they start making love—despite her protests of "We'll get caught, it's dangerous!" In the end, she's taken hard from behind, her hair disheveled as she moans and climaxes intensely. This forbidden affair, culminating in creampie, is captured entirely by hidden camera.
