When I secretly placed a hidden camera in the room of the AD's younger sister (a high school girl), I was able to capture more extreme footage than I expected! Furthermore, when I borrowed the video of my sisters that was taken with my brother's camera, I found that it was taken from a surprisingly good angle, so I couldn't help but record that video as well.

Hunter AD's younger sister is a high school girl who is so beautiful and slender that she is actually a model for a magazine. There is information that such a younger sister invites several male and female friends to her room and is holding a sleepover party! (Maybe it's a party where an orgy is inevitable...?) HUNTER's lewd sensor is activated! So the AD himself secretly filmed the rumored sleepover party...! He also obtained video footage of the sleepover, which was probably taken by his sister as a souvenir.
