I came to Tokyo to attend university, but I spent a sleepless night with the panting voice of Yuka, a married woman who lived next door. I couldn't believe that this ferocious, beastly voice came from a neat and elegant-looking girl. One day, Yuka-san invited me into her room because I had trouble sleeping. Then, as soon as I entered, she turned into a female beast and wrapped her body around me...! Yuka-san's wet and relentless caresses made me unable to think, and I just continued to play with my erect cock.
