A strange uncle who called out to me on the way home from school. Yui-chan, an innocent and unsuspecting Yui-chan, decided to go with me because she said she would treat me to a meal. The uncle is good at events and is practicing it. He begged me to accompany him to practice, and I was going to follow him… At first, I was skeptical and didn’t believe it. However, when I noticed, my body didn’t do what I said, and Yui-chan ended up being fucked as much as she wanted by her uncle. Yui who is forced to pee, has a lot of tides, is played with anal, and is used as an uncle’s toy. What will happen to her when the event is solved?
