Harley is plugged, diapered, and ready to submit to the twisted will of her sadistic diaper-wearing Mistress! The obedient slave bends over on the bed in anticipation, as her Mistress fetches a saline enema from the bedside table. Mistress opens up Harley's diaper, removes the plug from her ass, and empties the entire bottle inside of her, then taping the diaper back up to await the impending mess. Harley blushes, whines and fusses, feeling more and more desperate as the enema works its magic inside her belly. Soon, the poor girl can't hold it anymore, and Mistress encourages her to void her aching bowels into her diaper. Harley releases her enema in several stages, wailing and moaning as she does, resulting in the messiest diaper she's ever had! Mistress teases her stinky baby slave, patting and squishing her full diaper. As a final act of humiliation, Mistress holds a vibrating wand up against Harley's diapered pussy, giving her no choice but to cum in her own messy diaper! How embarrassing!
