A training record of disciplining Nana, a defiant niece with no blood relation, with love and raising her into an obedient beautiful girl pet. [Day 3 of captivity] Just two days into her new life, Nana attempts to run away but is captured again. Restrained with a collar and handcuffs, deprived of freedom, she spends the night unable to use the toilet or pull down her pants. While wiping her crotch, she unconsciously lets out moans. Aroused and feeling sexually excited, her urge to urinate intensifies and she wets herself in her freshly cleaned panties. After cleaning her up again, she is forced to wear a disposable diaper to prevent further accidents. [Day 8 of captivity] Nana has become somewhat tamer and is allowed to have her handcuffs removed. Her soiled diaper is taken off and her sweaty crotch is licked clean. Growing accustomed to sexual play, she begins to fondle and lick the cock like a toy. Stimulated by a vibrator through the diaper, her bladder reaches its limit and she wets herself again. [Day 15 of captivity] Nana has matured into a submissive pet. She shows affectionate gestures and increasingly displays feminine desires. As her arousal increases her urge to urinate, toilet training for pets begins. Her diaper is removed and she learns to pee in a pet toilet. Once she masters it, she plays with the cock like a cat with a teaser toy, scratching and nibbling while desperately serving the cock.
