Lala's mother is a world-renowned ballerina who must leave home for over a month to perform in London. She isn't just an artist—she's also internationally famous as a dominant BDSM queen. Before departing, she arranges a special, strict stay-at-home regimen for Lala, combining discipline and affection to prepare her daughter for a proper debut into high society. Believing that Lala must overcome her habit of wetting herself to become a refined lady, her mother leaves behind a peculiar but devoted "uncle pet" to assist in her toilet training. This "uncle" has a fetish for diapers and is tasked with helping Lala practice bladder control. Curious and playfully naughty, Lala enjoys her time with the uncle while striving to follow her mother's strict rules. Scenes unfold of her desperately holding in urine while wearing a diaper, having her soiled crotch cleaned by the uncle with a bidet, licking a large cock until it spurts white cum, and using a vibrator while mimicking BDSM videos to resist the urge to pee. Witness the whimsical yet embarrassing daily life of Lala's toilet training and solo stay, captured like an intimate documentary.
