Costume Fetish Chapter 1-3

An older brother's cruel blackmail scheme forces his reluctant sister into humiliating situations, starting with a deeply uncomfortable foot massage as she squirms under his lingering touch and makes him see her as a leotard. The humiliation escalates at school, where she must prance around a crowded gym in a tight leotard as leering teammates cheer her on for the 1600m run. Just when she thinks the torment is over, she discovers her brother's next twisted demand: a revealing latex costume sent to finish the job in front of the entire class.
