When Mary's Jane's step-mom Clare is about to leave, she tells her to make sure her adult step-brother Kade doesn't misbehave. And if he does, step-mom gives Mary Jane permission to spank her step-brother. Of course Mary Jane doesn't approve of Kade's behavior, so much to his chagrin, she makes him get over her knee for a long, hard spanking with her hand and hairbrush. He ends up humiliated and in pain! But he learns his lesson not to be a bad boy.
