Mistress Kat is training to be the perfect diapered submissive. Bunnie seems reluctant to be molded by her mistress, but Kat’s strict diaper discipline is going to break down Bunnie’s pitiful attempts at resistance. Mistress is still training Bunnie to obediently suck on her baby bottle, or anything else that's put in her mouth, without a second thought. Mistress' Pet isn't quite ready to give in to being bottle trained, and when she tries to avoid drinking another bottle of milk, Mistress Kat quickly moves on to punishing the disobedient pet. After Kat undoes Bunnie's thick cloth diaper, and gives her a firm bare bottom spanking until her cheeks are pink, Bunnie is much more eager to suck on the baby bottle's nipple when it's pressed to her lips. Bunnie certainly doesn't want to make Mistress Kat displeased again, especially since she's still left completely exposed by her open diaper. Once Mistress is satisfied that Bunnie is exhibiting the desired behavior, she wraps Bunnie back up in her soft, fluffy, comforting diaper before helping her pet finish all the milk in her bottle.
