My older sister, with some secrets, asked me to take care of her niece, Hinano. Hinano was rebellious and planned to run away from home early, so I put a collar and handcuffs on her to restrict her freedom. The next morning, Hinano couldn't go to the toilet and wet the bed. When I changed her wet underwear, I found that her crotch was wet with mucus that wasn't urine. She continued to refuse to eat, so I forced her to eat. She was so disobedient that I scolded her and slapped her until she cried. As her emotions grew, so did her sexual desire, and I made her give me a blowjob. After about a week, Hinano began to open up. However, her bedwetting habit persisted, so I made her wear a diaper to bed. Hinano complained of constipation and stomach pain, but there was no medicine. When I tried to remove her stool, Hinano felt aroused by anal stimulation. Continued stimulation increased her urge to urinate, and she leaked urine. I put her on my lap and spanked her bottom to make her reflect on her actions. After about two weeks, Hinano was able to go to school. As a reward for going out in a diaper, Hina is given ears and a tail. The tail with an anal plug attached to it makes her pee. After wrapping her penis in the diaper and making her give a handjob, she is made to give a blowjob.
