Your step-mommy hired one of your classmates to be your babysitter tonight. The problem is, she's a mean one. While looking in your younger step-sister's things, she found a pack of pink and purple Goodnites, pullup diapers for little bedwetters. Why would your parents take your step-sister on a trip without bringing her diaper bag? They must be yours then. Your babysitter decides to have you put them on and invite some friends over to have a slumber party. If you comply, she might let you wear PJ pants over your embarrassing training pants.
