[VEC-459] Mother's best friend Yumi Sakurai

Despite being an examinee, I was stuck because I couldn't concentrate on my studies. I can't go back to study until I pull out once, thinking about lewd things right away. It was a study that was plagued by such troubles, but my mother's best friend Yumi came to play there. The study that was completely fascinated by the glossy adult incense drifting from Yumi is absorbed in the comfort of studying ... Yumi has been there to see how she is going.
