BF-611 I had a fight with my wife, and my wife's sister pretended to care about me and seduced me, but I couldn't resist and ended up cumming inside her many times. - Rei Kuruki

Even before we got married, the three of us often played together with my wife's younger sister, Rei. - I thought she was cute, but I never thought of her as a member of the opposite sex. - Until that day... - One day, three years after I married my wife, I got into a fight with her and left home, and ended up at Rei's house with no one to go to. - "Hey... why did you marry your sister? Isn't it okay for me?" I thought it was a joke... but Rei boldly seduced me... I couldn't refuse.
