Before I got married, I often played with my wife's younger sister, Rei-chan. I thought she was cute... but I never thought of her as the opposite sex. Until that day... One day, three years after I got married to her wife, I got into a fight with her and left home. "Hey... Why did you marry your sister? Not me?" I thought it was a joke... Rei-chan boldly seduced me... I couldn't refuse.
