I was asked by my experienced older sister to take care of her niece, Hinano. Hinano is rebellious and quickly planned to run away from home, so I took away her freedom with a collar and handcuffs.
The next morning, Hinano couldn't go to the toilet and wet the bed. As I was changing her wet underwear, I found that her crotch was wet with a liquid that wasn't urine.
She continues to refuse food, so I force-feed her. She's being so unreasonable that I lecture her and slap her until she cries. As my emotions rise, so does my sex drive, and I make her give me head. After about a week, Hinano starts to open up. However, her bed-wetting habit doesn't improve, so I make her wear diapers at night.
Hinano complains of abdominal pain due to constipation, but there is no ●. When attempting to evacuate, Hinano gets aroused from the anal stimulation. Continuing the stimulation increases her urge to urinate, causing her to leak urine. She is made to sit on my lap and spanked as punishment.
After half a month, Hinano was able to go to school again.
As a reward for going out in diapers, I gave her ears and a tail. She intensely felt the anal plug tail and ended up wetting herself. After making her jerk me off while wrapped in a piss-soaked diaper, I made her give head.
