Gymnastics Schoolgirl Punishment by Nureki Chimuo.
Minami Lumine, Aya Mitsui, and Ayano Katsuragi, dressed in white gym clothes and black bloomers, are each tightly bound, and creatively tormented and punished by Nureki Chimuo. Minami Lumine is forced to walk through a knotted crotch rope as it rubs her crotch and thighs for some tightrope humiliation. Aya Mitsui is tied up in a tight armbinder and her red headband is used to gag her. Both her bloomers and white shorts are lowered, exposing and embarrassing her as the ties become more elaborate more intense. Ayano Katsuragi is bound tightly and subjected to shame and humiliation.
