A timer-programmed vibrator is secured beneath the girl's underwear. Initially, one-minute bursts of vibration leave her craving more, but as the intervals gradually lengthen to continuous stimulation, the intensity escalates. As time progresses—five, six, ten minutes—the girl is driven closer and closer to her limit. The highlight is watching Shizuku, a shy, modest A-cup girl with a strong sense of shame, react to this escalating situation. Additionally, fixed cameras capturing the girl's orgasm scenes feature new angles and enhanced production techniques designed to heighten excitement.
