Iris is locked in the pillory after being repeatedly told to stop bothering her step-sister. Seeing an opportunity, Bunny comes in a few minutes later and sneaks a mini-enema into Iris' bottom. Iris can't see who is doing this and assumes Step-Daddy is adding to her punishment.

When Step-Daddy returns a few hours later, he discovers Iris has made quite the mess of her diaper. When he asks her about, she insists he made her do it. After a bit of deduction, Step-Daddy realizes what actually happened and sends Iris to take a shower.
