What happens when a vibrator with timer-program function is fixed to a girl's underwear and continuous vibrations are delivered, gradually increasing in duration with intervals of one to two minutes? As time passes—five, six, ten minutes—the body grows increasingly sensitive. During this process, the girls gradually lose their rationality and are forced into climax, resulting in intensely realistic orgasm scenes. A fixed camera captures every detail, creating a vivid, immersive experience. The hypersensitive Ririka simultaneously pisses herself and climaxes, her experience unfolding like a scene from a movie. The progression toward complete mental breakdown unfolds dramatically, as if an uncontrollable incident is taking place.
