Riho Sasakawa and Rui Hizuki co-star for the first time!! I was living happily surrounded by my two proud older sisters. One day, my older sisters were noticed by a famous delinquent senior in the local area... The next day, he came into my house and started to use violence against me. In order to save me, I had to do as he said and let every inch of my body be devoured... I should have felt frustrated and disgusted, but gradually, a strange emotion started to well up from the depths of Kokoro...
