Overview

Even before we got married, I often played 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 girlfriend, I got into a fight with her, 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 she was joking... but Rei boldly seduced me... I couldn't refuse.
