Your bratty step daughter won't do her homework and is back talking you. You decide if she's gonna act like a bby then she'll get treated like one and you make her wear goodnites! She finally does what you say so that she doesn't get put in bby clothes too and starts to do her homework. But she gets distracted by the feeling of the pull ups and wets in them. Then she starts rubbing herself. You catch her in the act as she pulls out a vibrator toy. She yells at you at first, but then begs you not to tell her mom about the toy. You tell her you won't, but you want to see her play and she agrees. She pulls the goodnites to the side and fucks herself with the toy. She cums as she sucks your cock. She continues sucking and then lets you fuck her in the pull ups, calling you "Dad" and "Daddy". You cum all over her and her goodnites. Then suddenly she hears her mom is home and jumps up.
