Lolly tried to sneak off to school wearing a skirt so short it showed off her panties to anyone bothering to look. As punishment, Step-Daddy decides to put her into a diaper, so anyone looking up her skirt will get a real show. When she tries to refuse the diaper, he pulls her over his knee for a long, hard spanking. When she finally relents to being diapered, he lets her up and tapes her into the most babyish diaper he can find.
