What happens when a vibrator equipped with a timer program fixes onto a girl's pussy, continuously vibrating at intervals starting from 1 to 2 minutes, gradually increasing the duration? As the vibration time extends to 5, 6, even 10 minutes, the tension and excitement grow intensely. This release features three alibis: Hikaru, the horny idol; Kanna, an 18-year-old beautiful girl; and Mana, a cool, sweaty older sister indulging in masturbation. Building upon the fixed camera setup used to capture orgasms, this production introduces new elements for a more powerful and immersive experience.
