In a dimly lit, private gym, Dr. Lomp, a stern and dominant figure, awaits two brunette teens, Diana and Kate, who have been naughty. The girls, dressed in skimpy sports bras and tiny shorts, are made to strip down to their thongs, their pert asses on full display. Dr. Lomp, with a cruel smile, picks up a long, thin cane, tracing it along their spines, making them shiver. He orders them to bend over, their hands on the weight bench, their asses high in the air. The doctor begins their punishment, the cane striking their tender flesh with precise, measured strokes. The girls yelp and squirm, their asses turning a delicious shade of pink, then red.
