Step-Mommy Kat is worried about her little one, Nica, getting into trouble with boys. So, she takes her to the clinic to see Nurse Cara. Nurse Cara knows just what to do to make sure Nica won't be doing anything naughty with any boys! Once Step-Mommy gives her consent, Nurse Cara begins conditioning Nica to be totally diaper dependent. Nica won't be having any sex with anyone if she's stuck in diapers 24/7, and that's exactly what Step-Mommy Kat wants for her sweet little baby. Nica isn't so sure about all of this, but the decision isn't up to her and there's nothing she can do about it as Nurse Cara and her Step-Mommy work together to strip her naked and restrain her on the exam table. Nurse Cara gets a diaper under her right away and uses a special cream that makes Nica's princess parts extra sensitive, to help her learn to love diapers and diaper changes. While Nurse Cara is busy, Step-Mommy Kat distracts Nica by breastfeeding her to keep her calm. Before she knows it, Nica is powdered and wrapped up in her first diaper. Now she's ready to be transferred to the clinic's nursery, where she'll be staying until her diaper conditioning is complete.
