Rio-chan JS6 Botebara Doutei Kari

Rio is a sixth-grade elementary school student who discovers a strange power within herself. She can make anyone's belly swell up like a balloon, and she uses this ability to target and torment older boys who are still virgins. Rio takes pleasure in their humiliation and helplessness as she inflates their stomachs, calling it her "virgin hunt."

One day, Rio encounters a new victim, a high school boy who becomes the focus of her cruel game. As she uses her power on him, the situation escalates beyond her control, leading to unexpected consequences. Rio must confront the limits of her ability and the true nature of her desires.
