KSBJ-137 Tempted by my lustful brother-in-law's wife... Miki Matsuzaka

My brother's wife with a strong sex drive. Every day, my tsundere sister-in-law tempts me, making my days miserable. As soon as my brother leaves for work, she starts playing tricks on me. Sometimes she deliberately shows me her masturbation, and other times she displays their marital acts. Then it finally happened. When I was about to go to sleep, she sneaked into my room...and we crossed a line that should not have been crossed.
