Takeshi Karagi initiates a special project themed around sexual acts between relatives to fulfill clients' desires. A college student visits a massage parlor with her uncle, who invites her to receive treatment. Persuaded and feeling shy, she still accepts the massage, gradually seeking pleasure. Her body convulses from the vibrator stimulation, and as she surrenders to ecstasy, she is blindfolded and penetrated. She writhes in overwhelming pleasure, nearly losing consciousness. After her uncle finishes, she remains unaware that she has just engaged in incest. Craving the masseur's cock again, she climaxes repeatedly, loudly expressing her delight. This entire scene, secretly recorded, further emphasizes the plan's true purpose: fulfilling the client's request through hidden camera footage.
