Centered around a commercial facility, Toilet-kun operates primarily in a remote, depopulating rural area. Several months ago, he set up a hidden camera in a strategic location. During this time, he captured a young woman in the midst of puberty. Even through her shirt, her full, mature breasts were clearly visible, and he watched with a racing heart. Later, as she began touching her chest with one hand while holding her smartphone, he couldn't help but throw his hands up in triumph. A thrilling and humorous voyeuristic experience filled with excitement and tension.
