Harley has been disobedient lately, asking for changes, begging to use the potty, and talking back to her Mistress. It's clear that she needs to be reminded of her place! Mistress bends Harley over her lap, opening up her diaper tapes to pull it aside and putting on her latex gloves work on her naughty slave. She fingers Harley's ass with her lubed up latex fingers, making her fussy slave whine and squirm in humiliated overstimulation. The stern Mistress then lubes up a dildo and slides it inside of Harley, fucking her with it thoroughly and making the bratty diaper girl moan reluctantly. Afterwards, Mistress bounces Harley on her knee with the dildo still inside of her, removing it only after she decides that Harley has learned her lesson, at least for now.
