Bell and Star go to Mrs. Binkie's nursery for lessons in being good submissive babies for their caregivers. Mrs. Binkie puts Star in the crib in a baby straight jacket, to teach her not to wiggle and then uses a vibrator on her. Next, Mrs. Binkie wants to teach Bell to use her diapers, so she fills her tummy up with milk by breast feeding her and giving her a bottle. Then she shows Bell how to hump her stuffies before returning to help Star cum in her diaper with the vibrator. Once baby Star is all taken care of, Mrs. Binkie helps baby Bell cum in her wet diaper too.
