A girl who loves masturbating with a vibrator in her daily life, but this is her first experience with a 'timer vibrator'. She convulses as an extra-large penis attachment thrusts deep inside her, but due to the handcuff restraints, she's not allowed to stop midway—.'I'm cumming... I'm cumming again!' Her face contorts in ecstasy as she screams, and her hips unconsciously move. This is a non-stop 1-hour recording of maximum eroticism in the 'Aya' chapter. This series' first 4K compatible work.
