At first, it was just out of curiosity. I set up a hidden camera to spy on my niece "Kana" and her friend "Konatsu" when they came over to play, only to discover an unexpectedly erotic scene unfolding before me. One after another, the footage captured their lesbian play, aroused masturbation, sex with their boyfriends, and even acts of infidelity. Worse, they found out I had been secretly watching and masturbating to the recordings. As punishment, I was subjected to a humiliating office discipline session and forced into a brutal threesome. The story unfolds with me being thoroughly broken down and re-educated by the precocious, bratty techniques of these young girls.
