I came to my brother's and his wife's house during the summer vacation. Beautiful Chisato and her sister-in-law used to be a longing, kind and beautiful female announcer even though they had not met for a long time. The day I went to my brother's and his wife's house, Chi and my sister-in-law licked my injured finger. That night, when I was invited by my sister-in-law to have vaginal shot sex, my brother seduced me even though he was right next to me. I showed sex with my brother, and soon after, I played with my cock... and today I had rudimentary vaginal sex...
