Rihoko Sasagawa, Rui Hiizuki's first joint work!! Surrounded by my two proud older sisters, I was living a happy life. One day, my older sisters caught the eye of a notorious senior in our hometown... From the next day on, to save me from the DQN who barged into our home and used unreasonable violence, my older sisters became submissive and were exploited to the depths of their bodies... Though it should have been frustrating and unpleasant, gradually, a strange emotion welled up from the depths of my heart...
