My brother's wife with a strong sex drive. She tempts me every day, the tsundere sister-in-law who toys with me. 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. And finally, it happened. When I was about to go to sleep, she sneaked in…and we crossed the line that should not be crossed…
