Vibrator in een luier

Nicole loves binding herself in a diaper. Today she had a great idea! She gagged herself by solid leather gag harness (with a special gag ball inside). Then she placed a special remote panty vibrator in her diaper and turned it on with maximum power. The vibrator strongly stimulated her pussy, but it is just the beginning of the game! She bound herself to the walls and the ceiling with metal legcuffs, handcuffs, and thick chains. She is totally unprotected. What do you think? How long Nicole can hold back the orgasm?
