Clip for new Nicole’s boyfriend

Nicole met an interesting man on Internet recently. They both like Diaper Lover and BDSM fetish. They often share fantasies by chatting. Nicole decided to record the scenario that they talked about recently. She cuffed herself to the stairs and after several minutes she tried to get herself free, but unfortunately, she doesn’t have the right key. In several minutes Nicole strongly wets her diaper. How can she escape if she has the wrong key?
