We purchased a collection of spy photography materials (multiple individual restroom images) taken by a spy photography enthusiast! They have set up super-compact high-definition cameras in various places from Japanese-style to Western-style toilets. The images of 12 carefully selected schoolgirls, female office workers, and even married women masturbating (urinating)! We can't hide our surprise and excitement at the succession of unexpected events! The reason why the women's restrooms are always crowded...the heat in the private restrooms was even greater than I had imagined.
