True anal virginity loss. Nanami, a high school girl with an orthodox ladylike appearance, is sexually curious and agrees to have her first ever anal fuck in front of the camera. As she gains experience, starting with anal gaping and then finger insertion, she bleeds as her anus is stretched, but she eventually has her first ever anal ejaculation and even experiences a sandwich fuck... This is a 6-part documentary of a loli anal first penetration and raw creampie, depicting the tension, anxiety, and anticipation of a young girl experiencing anal fuck for the first time.
