The Watcher ~Haisetsu Gaman no Kanshisha~

It's the Autumn Festival. The event is packed. You happen to be in charge of overseeing the portable toilets. You've set up cameras inside the stalls, as you enjoy watching women piss, and unload their feces. Your other interest? Seeing women lose control, until they become incontinent. Here, you get to enjoy both, and record all the action on camera.
