Adult role-play based on U-Dash's popular indie series. Shame-addicted student council president Yuka Kimishima, played by Jun Suehiro, sinks into becoming a public gangbang toilet. No longer satisfied with exposing herself around the school, she roams a residential neighborhood indecently dressed, trembling under strangers' stares. A strange man approaches and the encounter leads to sex. Craving an even greater thrill, she binds herself naked in a park at night, and when a passerby discovers her, excitement makes her pussy overflow.
