I ended up living with my brother and my wife for a while. At first, I didn't see my brother's wife as a woman, but... My brother's wife, who hasn't had sex with me for over three years, seduces me from the start...I started to worry about my brother's wife... and finally, I couldn't hold it in and we ended up having sex on a business trip! It's so responsive I got carried away and thrust hard from underneath to a high-speed piston! I was so masturbated that I thought I'd blow my mind over and over again!
