What happens when a timer-programmed vibrator is fixed to a girl's pussy, delivering continuous vibrations at intervals of one to two minutes, gradually increasing the duration over time? As time passes—five, six, ten minutes—the situation becomes increasingly intense. Featuring three girls: "Mei," the climax machine; "Ringo," the mysteriously transformed oddball; and "Sakura," who cries tears of confusion. The setup, which captures their orgasmic moments in real time using fixed cameras, delivers an incredibly exciting experience.
