A training record of how to lovingly discipline the rebellious niece Nana, who is not related by blood, and raise her to be an obedient beautiful pet. [Day 3 of her life as a pet] Nana attempts to run away from home, but is restrained with a collar and handcuffs and deprived of her freedom. Two days into her new life, Nana attempts to run away from home, but fails. She is confined with a collar and handcuffs. Naturally, she cannot go to the toilet, and she cannot take off her pants, so she spends the night in the pants she has wet herself in. While wiping her crotch, Nana lets out a moan. It seems that when she gets horny, her urge to urinate increases, and she wets herself even though she has just been cleaned up. After being cleaned up again, Nana is forced to wear a disposable diaper to prevent wetness. [Day 8 of captive life] Nana has become more accepting of sexual training. Now that she has calmed down a bit, she is allowed to remove the handcuffs. She removes her dirty diaper and licks her moist crotch to clean it. She has also become accustomed to sexual play, playing with and licking a penis like a toy. When she is stimulated with a vibrator through her diaper, her urge to urinate exceeds her limit and she loses control. [Day 15 of her life as a captive] A loving life with obedient pet Nana] Nana has become obedient as a diaper pet. She shows cute behavior and her desires as a woman seem to be getting stronger. As expected, when her crotch feels good, her urge to urinate increases, so toilet training is done so that she can use the pet toilet. After removing her diaper, Nana urinates in the pet toilet. Now that she can pee properly, she plays with the penis as if it were a cat toy. She scratches, nibbles, and fools around while earnestly servicing the penis.
