During summer vacation, I came to stay at my brother's house. My beautiful sister-in-law Chisato, a former female announcer whom I had always admired, was kind and beautiful even when we met again after a long time. On the day I arrived at my brother's house, my sister-in-law Chisato licked my injured finger. That night, my sister-in-law invited me to have creampie sex with her, and ever since then, she has been seducing me even though my brother is right next to me. She shows me her sex with my brother, and plays with my dick right after... and today we had raw creampie sex again...
