Olivia didn't do her house chores, so Nicole decided to punish her. She cuffed Olivia by chain handcuffs (behind her back), which were attached to ceiling mounted chain to prevent Olivia from escaping from her predicament. Nicole mounted a powerful vibrator to Olivia's leg for making her orgasms by her wet diaper. Nicole had to be sure, that Olivia doesn't free herself and will be properly punished (that she won't be able to turn off vibrator and take off diaper), therefore she applied additionally thumbcuffs.
