Diapered girl on a bed

This time Nicole has been handcuffed to a bed by one of her roommates, Susie. Nicole is lying on the bed chained and handcuffed, on top of being gagged. Her diaper is already very wet. Nicole is totally helpless and immobilized. Her ankles, wrists, waist, knees and elbows are chained to the bed. Moreover her diaper is also chained and padlocked. Susie took all the keys to the chains and padlocks with her when she left the house, so even if Amanda (Nicole's other roommate) comes home earlier she won't be able to free Nicole or even change her diaper, because it is too locked by the chains.
