When Kathrin realises that Alex has gone out, she decides that his bedroom could be the perfect place for having some private moments pleasuring herself. While enjoying her self administration, Alex has unexpectedly returned home and entered his room. He’s very angry with her and immediately puts the girl in the humiliating diaper position for a good hand spanking. Then with an already bruised bottom, Kathrin is ordered to fetch the wooden spoon from the kitchen. On her return Alex puts her over his knee and proceeds to make her poor bottom even sorer.
