I secretly took pictures of a girl's upskirt on the train with my smartphone. She was showing it off on purpose! I mustered up the courage to talk to Rio, a student, and she agreed to let me take pictures of her upskirt for free! At the hotel, I dressed Rio in her school uniform, knit sweater, and anime cosplay and took as many pictures of her upskirt as I wanted! As she was filmed in close-up, she got more and more excited and started asking for a dick, making her the ultimate upskirt doll.
