Vibrator under a chastity belt that turns on at random times, with random duration.
>At random times of the day and night she will be brought low by overwhelming stimulation she has no control over.
>When the vibration starts she never knows if it will last 1 minute of 1 hour.
>When it ends she never knows if it will come back the next day, in the middle of the night, or in 10 minutes.
>Only her handlers take off the chastity belt, while she's tied and blindfolded. They clean her and recharge the vibrator's battery.
After a few weeks she'll realize that other people know her body better than she does.
