My younger brother's wife has a strong sexual desire. I am at the mercy of my younger brother's wife who seduces me almost every day. As soon as my younger brother goes to work, she starts to play pranks on me. Sometimes she purposely shows me how she masturbates, and other times she shows me how she and her husband have sex. And finally it happened. She sneaks in when I'm about to go to sleep... and we cross a line that should never be crossed...
