A strange uncle called me on the way home from school. It seemed like she wanted to practice her magic for a certain event. Yuka was innocent and didn't know how to doubt. If you notice your uncle's charm, your uncle will become your best friend. At first I was skeptical and didn't believe it, but when I realized it, my body didn't listen to what I said and my uncle would do whatever I wanted. Yuka-chan was forced to pee, forced to pee a lot, fucked anally, ejaculated into her vagina, and turned into his toy. What will happen to her when the event is resolved?
