Katherine thinks her new babysitter, Chelsea, is perfect in every way; blonde hair, killer body, and breasts to die for. When she catches Chelsea in an act of passion with another girl, in her house, it's all Katherine can think about.
When she finds Chelsea, barely wearing a bikini and plucks up the courage to touch her, she finds out her husband, Robert, and Chelsea have already talked things over and have plans for her.
They take her upstairs, strip her off, and make her wear her diaper. While to some this might be weird or taboo, to Katherine it seems too good to be true, but will it give her access to Chelsea's amazing body?
