Schoolgirl Carissa has forged her step-father's signature. Her step-mother (played by Clare Fonda) has told her that her step-father would spank her, and spank her he does. First over her shorts (she had to change out of her school uniform because she peed in it) while her step-mother lectures her. Then her step-mother steps out to let step-dad spank Carissa over her panties.
