Raping a very beautiful ballet student

Yu is a girl who is studying ballet, she is beautiful and practices very hard. Yu respects me very much because I am her teacher. In class there is an older guy named Takahashi. One day I accidentally saw Takahashi raping Yu in a private room. I was about to go stop it when I saw that Yu was happily raped. So I realized how much of a love-hungry girl she was. Then one day, I wanted to rape her too.
