A strange man approached me on my way home from school. He seems to want to practice a hypnotic spell. Yuka is an innocent girl who has no doubts. Through his hypnotic spell, she finds that he has become her best friend. At first she doesn't believe him, but then she realizes that her body doesn't listen to him and her as much as he wants. Yuka is made to pee, squirt a lot, have her anus twitch, get cum inside, and so on... She becomes his toy. What will happen to her when the hypnosis is broken?
